        In order to attain the goal of having ranges act like they are
        always in the C locale, bit the bullet and did the work in
        the regex and dfa engines. The pre-processing routine was not
        handling too many cases that a full regexp parser would catch.

        Fatal error if end point is below start point ([z-a]),
        thanks to John Haque.  Don't repeat the last character in
        the expansion. Thanks to Arnold Robbins.

        * main.c (varinit): Give FPAT a reasonable default value.
        * field (get_field): Adjust test for at end of record to >=;
        fpat_parse_field can go beyond when matching null regexps.
        Thanks to Pat Rankin.

Fri May 20 11:00:17 2011  Arnold D. Robbins  <arnold@skeeve.com>

        * regex_internal.h (__attribute_warn_unused_result__): Always

                        > more awk statement(s)
                        > end
        p1, p2 are eval locals.
        Conditional break/watch point:
                break 1 "condition expression"
                        OR
                break 1

        Changes from August 2008 through February 2009 to add
        BEGINFILE and ENDFILE, originally against 3.1.6, merged into
        development version.

        * awk.h (in_beginfile_rule, in_endfile_rule): Add declarations.
        * awkgram.y (beginfile_block, endfile_block): Add declarations.
        (beginfile_or_endfile_rule, parsing_endfile_rule): New variables.
        (LEX_BEGINFILE, LEX_ENDFILE): New tokens, new rules for those tokens.
        (tokentab): Add new entries for BEGINFILE, ENDFILE.
        (LEX_NEXTFILE): Allow nextfile in BEGINFILE rule.
        (LEX_GETLINE): Allow only `getline var < file' inside BEGINFILE or
        ENDFILE.
        * eval.c (interpret): Check in_beginfile_rule and in_endfile_rule for
        errors for next and nextfile.
        (update_ERRNO_saved): When errno == 0, set to ERRNO to
        null string.
        (interpret): Allow nextfile in BEGINFILE rule.
        (update_ERRNO_saved): Check errcode paramater, not global errno.
        * io.c (beginfile_block, endfile_block, in_beginfile_rule,
        in_endfile_rule): New variables.
        (do_input): Set them.  Update ERRNO only if not do_traditional.
        Propogate error code down to fatal message.
        (run_beginfile_rule, run_endfile_rule): New functions.
        (iop_alloc): Use it instead of inline code.  Add fourth argument
        indicating that the open hooks should run. Adjust calls.  Point is
        to not call open hooks twice inside `nextfile'.
        (do_nextfile): Check it and also in_beginfile_rule and only longjump
        when both filebuf valid and not in a BEGINFILE rule.
        (nextfile): Call run_beginfile_rule and run_endfile_rule as
        appropriate.  Reorder the logic to set ERRNO and allow BEGINFILE
        to call nextfile to skip a bad data file.  Adjust calls to
        iop_open and find_open_hook.
        (nextfile): Call iop_alloc if there's a BEGINFILE block in case
        the hooks changed.
        (find_open_hook): New function.
        (get_a_record): On read error, just set *errcode and return. Let
        higher level logic decide if it's fatal.

        an ENDFILE rule.
        * profile.c (dump_prog): Add code for BEGINFILE / ENDFILE.
        * awk.h (dump_prog): Adjust declaration.
        * main.c (main): Adjust call to `dump_prog'.  Check beginfile_block and
        endfile_block also to be not NULL in order to call do_input. Thanks to
        Steffen Schuler for pointing out the bug.

Thu Feb 26 07:54:51 2009  Arnold D. Robbins  <arnold@skeeve.com>

        Per advice from BWK and my own feelings, nuke additions from 2001

        is called indirectly. Also get scoping right if called from a function.
        LOTS of work here to get this code right!
        (op_assign): Add ASSIGNED to flags.
        * awkgram.y (function_call, direct_function_call): New productions for
        creating indirect function calls. Only call func_use for direct call.
        (yylex): Add case for '@'. Only return it if not posix or traditional.
        * profile.c (tree_eval): Add case for Node_indirect_func_call.
        (pp_func_call): Check type and print '@' for indirect call.

        to turn it on.  New function  val = mark("/some/file")  to
        save start position of current record.  Use
        reset("/some/file", pos) to go back to it.  ONLY works
        with getline.

        * awk.h (IOBUF): New members save_start and rec_size.

Tue Sep 14 09:53:55 2010  Arnold D. Robbins  <arnold@skeeve.com>

        * node.c (str2wstr): Per advice from Ulrich Drepper, when converting,
        if the current byte is isprint, isgraph, iscntrl or zero, then it
        can't start a multibyte character. This can save many calls to
        `mbrtowcs', and speed up the conversion considerably.

Fri Aug 20 16:26:14 2010  Arnold D. Robbins  <arnold@skeeve.com>

        * profile.c (tree_eval): Always parenthesize Node_cond_exp.
        May add a few extra parens but guarantees the right semantics.
        Thanks to Hermann Peifer <peifer@gmx.eu> for the bug report.

Thu Aug 19 21:35:13 2010  Arnold D. Robbins  <arnold@skeeve.com>

        * re.c (make_regexp): Don't allocate rp->dfareg unless
        we're using dfa; causes a memory leak otherwise. Thanks to
        Antonio Columbo for reporting the bug.

        of other awks.
        (print_expression_list): Simplified so that something like

Fri Jun  4 15:56:59 2010  Arnold D. Robbins  <arnold@skeeve.com>

        * dfa.c: Further merges with GNU grep.

        * ltmain.sh: Removed.
        * builtin.c (do_mktime): Restored old code to match the
        documentation. We now have a warning that we just have to

        (format_tree): More code so that %'d acts like %d on systems
        without <locale.h>.
        * main.c (main): Add `&& #if defined(HAVE_LOCALE_H)' for

        Vinschen.
        * dfa.c: Enum body here.
        (in_coll_range): z/OS fix: Initialize array to all zeros and assign

        separator character, don't let `quote_flag' have an effect. Fixes

        * array.c (assoc_lookup): In lint warning, don't clobber
        the character at the end of the subscript; instead use the
        length to limit the number of characters printed. Thanks to
        Nick Hobson <nick.hobson@yahoo.com>.

        first make sure that <dig> is within the range of parentheses sets
        given, and then make sure that the subpattern start is not -1, meaning

Thu Apr 16 22:59:32 2009  Arnold D. Robbins  <arnold@skeeve.com>

        * eval.c (func_call): Save nloops_active; if after function returns
        the actual nloops_active is greater than the saved value, it means
        there was a return inside the loop body, so pop off the necessary
        number of loops.  Bug reported by Aleksey Cheusov <a.cheusov@gmail.com>.
        Gawk was not leaking memory - that is, things were still pointed
        to, but memory use could keep on growing.

Fri Mar 27 10:59:11 2009  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (format_tree): Add lint warnings for fieldwidth and/or

        (stackoverflow_context_t): Dummy typedef for use in prototypes;
        (stackoverflow_install_handler): Make macro expand to 0 rather

        * profile.c (pp_delete): Print tree->exec_count to actually get
        the value printed. Thanks to Hermann Peifer <peifer@gmx.eu>
        for reporting the bug.

Thu Feb 12 21:54:34 2009  Arnold D. Robbins  <arnold@skeeve.com>

        * re.c (reflags2str): Account for RE_SYNTAX_EMACS.
        * awk.h: If not VMS, define HAVE_SIGSEGV_H.
        * main.c: Check HAVE_SIGSEGV_H before including <sigsegv.h>. If not
        there, define dummy macros.
        (catchsegv, catchstackoverflow): Remove unneeded comment. Add return 0
        for compilers that care.

Mon Feb  9 05:24:52 2009  Arnold D. Robbins  <arnold@skeeve.com>

Sat Jan 31 23:14:00 2009  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (format_tree): For '%s', don't count the multibyte
        characters if we are just copying all the characters. Gives
        big speedup. Thanks to Hirofumi Saito <hi_saito@yk.rim.or.jp>
        for reporting the problem.

Thu Jan 29 21:14:30 2009  Arnold D. Robbins  <arnold@skeeve.com>

        * eval.c (interpret): Map exit value from `exit' statement into
        success / fail constants for VMS for exit_val variable.

Tue Jan 20 07:35:34 2009  Arnold D. Robbins  <arnold@skeeve.com>

        * regex.h: Define __USE_GNU if not _LIBC; needed for non-GLIBC
        systems such as, oh say, Mac OS X.

Tue Jan 13 09:23:40 2009  Arnold D. Robbins  <arnold@skeeve.com>

        * regex.c, regex_internal.h: Remove some changes that are no

Mon Jan  5 23:07:58 2009  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (devopen): Add a retry to calls to socketopen. Tunable
        via undocumented GAWK_SOCK_RETRIES environment variable. Based
        on code from Juergen Kahrs <Juergen.Kahrs@vr-web.de> after a
        suggestion from Hermann Peifer <peifer@gmx.eu>.

Mon Jan  5 22:48:39 2009  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (redirect): A getline from a directory is no longer
        fatal; instead it returns -1. Thanks to Paolo <oopla@users.sf.net>
        for the report.

Mon Dec 29 22:04:57 2008  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (format_tree): Case for 's', improve logic for setting
        the number of characters to copy, also at pr_tail. Based on
        bug report by Hermann Peifer <peifer@gmx.net>.

Thu Dec 11 21:23:50 2008  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (do_length): If the wide string has zero length
        but the bytes are more than zero, use the number of bytes.
        (do_index): Similar also: fall back to byte count if the
        bytes don't make a wide-character string.
        Bug reported by "Carlos G." <charlie.brown.uy@gmail.com>

        (do_substr): If defaulting to length of rest of the string,
        do it based on the wide char string if it's valid.

Thu Dec  4 22:35:05 2008  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (redirect): Only put the new struct redirect into
        the list if the file or pipe could actually be opened. Fixes
        a bug with the wrong return value of close, noticed by
        Seb <sbb@tuxfamily.org>.
        * dfa.c (parse_bracket_exp_mb): Don't zero out work_mbc->chars
        after we malloc'ed it. Fixes a leak found by valgrind when
        using UTF-8.  (Hmmm. This got fixed in January 2007; It seems
        to have crept back into the code in the August 2007 merge with
        GNU grep. Sigh.)

Mon Oct 20 11:47:59 2008  Arnold D. Robbins  <arnold@skeeve.com>

        * configure.ac: Add -g3 and -gdwarf-2 to CFLAGS if compiling with

Wed Jul 30 23:10:51 2008  Arnold D. Robbins  <arnold@skeeve.com>

        * re.c (research): Don't ever use DFA if need_start. It can
        break on some weird cases.  Reported by
         "T. X. G." <leopardie333@yahoo.com>.

Wed Jul 30 22:27:20 2008  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (do_match): Add MAYBE_NUM flag to elements of array
        created by `match' since data could come from user. Similar
        semantics to `split'. Thanks to Dr. Dirk Zimoch <dirk.zimoch@psi.ch>
        for reporting the bug.

Tue Jun 24 07:44:06 2008  Arnold D. Robbins  <arnold@skeeve.com>

        variables instead of a break. Thanks again to Hermann Peifer
        <peifer@gmx.eu> for finding the problem.

Sun Jun 22 23:08:14 2008  Arnold D. Robbins  <arnold@skeeve.com>

        * node.c (format_val): Restore old code to use %ld when the value
        is within the range of a long; improves performance noticably for
        applications that convert integers to strings.  Use %.0f only for
        integral values that are outside the range of a long. Thanks to
        Hermann Peifer <peifer@gmx.eu> for pointing out the existence
        of a problem.

Fri May 23 12:08:24 2008  Arnold D. Robbins  <arnold@skeeve.com>

        * dfa.c (epsclosure): Change type of `visited' from int to char for

        * main.c (main): Move call to catch SIGBUS to before installation of
        libsigsegv handler, since on some systems libsigsegv installs its
        own handler for SIGBUS.
        [STACK_SIZE]: Add a constant instead of inline. ADR.

Wed Apr 23 22:30:27 2008  Duncan Moore       <duncan.m00re@btinternet.com>

        * builtin.c (state): Do as an integer array for systems that need it.
        (do_rand, init_rand): Modify call to `initstate' as needed.

Wed Apr 23 22:22:06 2008  Arnold D. Robbins  <arnold@skeeve.com>

        * dfa.c (prednames): Add an extra zero to final initializer to
        silence a compiler warning. Reported by Duncan Moore
        <duncan.m00re@btinternet.com>.

        * builtin.c (mbc_char_count, mbc_byte_count): New functions to return
        the number of m.b. chars there are and the number of bytes needed to
        copy them.
        (format_tree): Use them for %s and %c cases to adjust precision and
        for copying characters at pr_tail label.

Thu Feb 14 14:05:01 2008  Arnold D. Robbins  <arnold@skeeve.com>

        * main.c (init_args): Adjust type of third arg to remove warning from
        GCC 4.2, add cast in call to make_string.  Bleah.

Tue Sep 25 23:27:41 2007  Arnold D. Robbins  <arnold@skeeve.com>

        * ChangeLog: Removed all leading spaces. Fixed up formatting of
        entries to have capital letter after the colon. Fixed a number of
        entries to have the '*' in the right place. ASCII instead of ascii.
        Capitalize Linux. (Is this anal-retentive or what? Sheesh.)

Tue Sep 25 08:24:11 2007  KIMURA Koichi      <kimura.koichi@canon.co.jp>

        * awk.h: Add include of <io.h> for Visual Studio.

        for pointing out the problem.

        Unrelated:

        array later.
        (grow_table): Use the saved code instead of recomputing each time.

        General capability suggested by Michael May <mmlpz@t-online.de>.

        * configure.ac: New option --disable-directories-fatal. Makes gawk
        silently skip directories on the command line.
        * io.c (iop_open): Add fourth parameter, pointer to flag which is set
        to true if the file is a directory. In this case, close the fd and
        return NULL.
        (nextfile): Modify call to iop_open. Add logic to check for directory
        and skip if --disable-directories-fatal was used. If the configure flag
        was not used, then if do_traditional also skip.
        (redirect): Modify call to iop_open and call fatal if isdir is true.

Mon May  7 14:51:54 2007  Arnold D. Robbins  <arnold@skeeve.com>

        the rule for "(...) in arr" to ...
        (non_post_simp_exp): ... here ...
        (simp_exp): ... and here, respectively. Fixes test/parsefld.awk/.
        (simp_exp_nc): New nonterminal, needed to fix the
        precedence of concatenation over "|getline".
        (common_exp): Can also start with simp_exp_nc.

Tue May  1 19:53:11 2007  Arnold D. Robbins  <arnold@skeeve.com>

        * dfa.c (dfainit): Initialize it to false.
        (lex): Set it if `minrep == maxrep && minrep == 0'.
        * re.c (avoid_dfa): Check flag and return TRUE if set.

Tue Apr 24 21:55:36 2007  Arnold D. Robbins  <arnold@skeeve.com>

        * re.c (research): In the multibyte case, fall back to the full
        matcher if need_start, since there are bugs in the dfa matcher
        in some obscure cases.  Sigh.
        * builtin.c (format_tree): When using %.0f instead of %d, assert
        that we're not malloc-ing zero.

Tue Apr 10 18:53:04 2007  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y, builtin.c, eval.c, ext.c, field.c, io.c,
        node.c: Added some sanity to the lint warnings, to only
        print them once if they are syntactic or of the type where
        they don't need to be repeated. Switch to `short' instead
        of `int', and in general use a variable named `warned', for
        consistency.

        Tandem, needed on some Unix systems.
        * awk.h, main.c, msg.c, awkgram.y: Move to use of CAN_USE_STDARG_H
        instead of continuously repeating check for header and defined STDC
        and STDC. Thanks to Pat Rankin.

Fri Apr  6 15:28:09 2007  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (do_length): Only print `length(array)' lint warning once.

        * node.c (is_ieee_magic_val): Don't rely on strncasecmp; it mishandles
        ASCII bytes in some locales.
        (get_ieee_magic_val): Use strtod if it works, relying on our handbuilt
        code only if it doesn't work.  This is more likely to do the right
        thing with strings like "-nan".

Tue Feb 27 20:51:29 2007  Arnold D. Robbins  <arnold@skeeve.com>

        * configure.ac (AM_PROG_CC_STDC): Removed, per email suggestion

        also. Avoids problems with empty regex and IGNORECASE on
        systems where `malloc(0)' returns a non-NULL pointer.
        From mail dated Wed, 26 Oct 2005 15:42:07 -0700.

        correct declarations of math functions.
        * configure.ac: If doing development, add -DYYDEBUG and also
        -fno-builtin for GCC.

Wed Feb 14 19:42:08 2007  Arnold D. Robbins  <arnold@skeeve.com>

        Add support for special infinity and NaN values in non-POSIX

Fri Jan 26 20:01:38 2007  Andrew J. Schorr <ajschorr@users.sourceforge.net>

        * node.c (format_val): Test whether a numeric value is integral
        simply by converting it to long and then back again, and checking
        if the value matches.  That's more robust than trying to test
        whether the floating-point value is representable as a long.
        * builtin.c (format_tree): Fix buffer overflow bug, off-by-one errors
        in checking snprintf return codes, and use "%.0f" to implement "%d"
        formatting.  For octal or hex formatting, test whether the value
        is integral by trying to convert back to floating point and seeing
        if the value matches.  This is more robust than trying to test
        whether the floating-point value is representable as an integer.

Tue Jan 23 17:49:28 2007  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (socketopen): Initialize socketfd to avoid "may be used
        uninitialized" warning.
        * regexec.c (regexec, re_search_stub): Removed unused variable `dfa'.
        * builtin.c (wide_tolower_toupper): Fix signedness of pointer in
        allocation calls and in call to make_str_node.

Mon Jan 22 12:57:19 2007  Kimura Koichi    <kimura.koichi@canon.co.jp>

        Deal with halfwidth katakana in SJIS locale inside character ranges.
        Based on http://sources.redhat.com/bugzilla/show_bug.cgi?id=1149.
        Changes affect non-__LIBC code only.

        * regcomp.c (re_compile_fastmap_iter): Handle half-size characters.
        * regexec.c (check_node_accept_bytes): Same.

        * regcomp.c (re_compile_fastmap_iter): Declare `dfa' to be
        be volatile. Fixes valgrind problem with the ignrcase test.
        Sheesh.  Gawk should now be valgrind-clean. We hope.

Mon Jan 15 14:28:04 2007  Arnold D. Robbins  <arnold@skeeve.com>

        Use getaddrinfo instead of gethostbyname, to handle IPV6

        * replace.c: Include getaddrinfo.c if necessary.

Sun Jan 14 12:19:53 2007  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y: For bad name in array subscripting, build a
        valid node anyway to avoid invalid reads reported by valgrind.
        * dfa.c (parse_bracket_exp_mb): Remove assignment of NULL
        to work_mbc->chars, was losing data malloc'ed earlier. Thanks
        to valgrind.
        (state_index): Alway initialize d->states[i].mbps elements to zero.
        (dfafree): Free allocated d->states[i].mbps.elems if needed.

        * node.c (str2wstr): For count of zero from mbrtowc, set count to 1
        and fall through to code that copies. Originally from Paul Eggert.

        Unrelated:
        * configure.ac: Add call to AC_USE_SYSTEM_EXTENSIONS, should help
        on Tandem. This lets us remove AC_AIX and AC_MINIX.

        From Matthew Woehlke <mwoehlke@tibco.com> for Tandem:

        * awk.h (_TANDEM_SOURCE): Also define _XOPEN_SOURCE_EXTENDED.

        `index in array' outside of for loops, multidimensional arrays.
        * field.c (set_FS): Warn about regex FS.
        * node.c (parse_escape): Warn about `\b', `\f', `\r'. 

Sat Jan 13 20:56:56 2007  Arnold D. Robbins  <arnold@skeeve.com>

        * node.c (wcasestrstr): Revert use of continue, reinstate goto.
        Thanks to Andrew Schorr.
        (free_wstr): Move zeroing of wsptr and wslen and clearing of flag
        back outside the if.
        * field.c (rebuild_record): In loop that copies fields to new record,
        add call to `free_wstr'. This ensures that flag values are correct
        and avoids double free later. Thanks to Karel Zak for pointing out
        the problem.

Fri Jan 12 14:01:51 2007  Dmitry V. Levin  <ldv@altlinux.org>

        * builtin.c (do_match): In addition to "gawk_mb_cur_max > 1" check,
        check for positive string length.

Fri Jan 12 13:57:20 2007  Arnold D. Robbins  <arnold@skeeve.com>

        * node.c (unref): Call `free_wstr' for fields also. Thanks to
        Andrew Schorr.

Tue Jul  4 22:43:05 2006  Arnold D. Robbins  <arnold@skeeve.com>

        * eval.c (interpret): Node_assign_concat case: Turn off NUMBER and
        NUMCUR flags in result.  Sheesh. Thanks to
        <Heiner.Marxen@DrB.Insel.DE> for finding the problem.

Mon Jul  3 22:49:44 2006        Pat Rankin      <rankin@pactechdata.com>

        * main.c (load_environ): When AWKPATH is missing from ENVIRON[],
        try to find it with getenv("AWKPATH") before resorting to DEFPATH.
        Suggested by Galen Tackett.

Mon Jul  3 00:27:59 2006  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (INTERNAL_HANDLE): New constant for use by `iop_alloc'
        when allocating an internal IOBUF.
        (pidopen, useropen): Use it.
        (iop_alloc): Add check for it and just return iop.

Fri Jun 23 15:48:34 2006  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y (subn): At end for `do_sprintf' check, verify
        that lnode is not NULL before using it to assign through.

Sun Jun 18 22:27:25 2006  Arnold D. Robbins  <arnold@skeeve.com>

        Repair internal names like /dev/user, /dev/pid, as well as /dev/fd/N,
        which have been broken for a long time but noone noticed.

        * io.c (is_internal): New macro to check for internal file like
        `/dev/user'.
        (spec_setup): Reduce to two parameters, allocate logic is always true.
        Add IOP_NO_FREE to flag.
        (pidopen, useropen): Return `IOBUF *' instead of int. Fix
        logic to test if `iop' parameter is NULL and if so to allocate it.
        (specfdopen,): Return `IOBUF *' instead of int. Fix
        logic to test if `iop' parameter is NULL and if so to allocate it.
        Don't set IOP_NO_FREE in flag.
        (iop_open): Remove `IOBUF iob' field from `struct internal' and its use
        and the use of `spec_setup' from the code here. Change the check in the
        call to the open function to look for NULL.
        (get_a_record): Use `is_internal' in initial check for filling the
        buffer to not try to call `read' on internal files. If true, set
        the IOP_AT_EOF in the flag and return EOF.

Fri Mar 24 13:05:56 2006  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y (get_src_buf): Remove function argument types from
        declaration of `readfunc' to avoid bugaboos with VMS declaration
        of `read' system call.

Fri Mar 10 06:28:23 2006  Arnold D. Robbins  <arnold@skeeve.com>

        * awk.h (free_wstr): New declaration if MBS_SUPPORT, empty macro
        otherwise.
        * node.c (free_wstr): New function, inside MBS_SUPPORT. Frees the wide
        string part of a node. Provided so that it can be used consistently
        everywhere.
        (format_val, r_dupnode, mk_number, make_str_node, unref): Use it.
        * builtin.c (sub_common): Call `free_wstr' instead of doing it manually.
        * eval.c (r_tree_eval): Same in Node_assign_concat case.
        * field.c (set_field, rebuild_record, set_record): Add calls to
        `free_wstr'.

Mon Feb 13 22:45:34 2006  Arnold D. Robbins  <arnold@skeeve.com>

        * eval.c (r_tree_eval): Node_assign_concat. Release any
        wide string value and reset the WSTRCUR flag. Based on
        bug report by Karel Zak.

2006-01-03  Paul Eggert  <eggert@cs.ucla.edu>

        * Makefile.am (awkgram.c): Use $(AWK), not awk, so that the rule
        works on Solaris too (e.g., Solaris 10).  Problem reported by
        Andrew J. Schorr.

Mon Dec 19 05:39:46 2005  Arnold D. Robbins  <arnold@skeeve.com>

        * node.c (format_val): Account for overlow of conversion
        from double to long. Shows up worse on 64-bit systems.

Wed Dec 14 18:57:34 2005  Arnold D. Robbins  <arnold@skeeve.com>

        * eval.c (set_BINMODE): Fix logic of test for no numeric value.
        Makes `gawk -v BINMODE=1 ...' work again. Thanks to Eli Zaretskii
        <eliz@gnu.org> for pointing out the problem.

Wed Oct 19 10:58:27 2005  Arnold D. Robbins  <arnold@skeeve.com>

        * main.c (main, arg_init): Only use the locale's decimal
        point if do_posix is set. Too many people the world over
        have complained about this.

Fri Oct  7 13:54:09 2005  Arnold D. Robbins  <arnold@skeeve.com>

        Enhancement to fix from 23 Sept 2005, suggested by Pat Rankin.

        * awkgram.y (one_line_close): New function, closes open FILE * used
        by `read_one_line'.
        (fp): Static FILE * used by `read_one_line' and `one_line_close'.
        * awkgram.y (read_one_line): Simplify check for call to `fdopen'.
        (get_src_buf): New variable `closefunc' which is a pointer to a
        function implementing the `close' system call interface.

Fri Oct  7 13:23:29 2005  Arnold D. Robbins  <arnold@skeeve.com>

        * field.c (set_FIELDWIDTHS): Fix off-by-one error in assignment
        of sentinel value at end of FIELDWIDTHS array.

Fri Sep 23 16:05:13 2005  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y (read_one_line): New function, mainly for debugging,
        that reads one line of data at a time to pass back as a buffer.
        Emulates the variable-length record filesystem of VMS, where
        we first saw the problem fixed here.
        (get_src_buf): New variable `readfunc' which is a pointer to a
        function implementing the `read' system call interface. Based on
        an environment variable, use `read_one_line' instead of `read'
        for testing.   Make the test for expanding the buffer smarter,
        so that it doesn't grow unnecessarily.

        Thanks to Galen Tackett (tackett_galen@bah.com) for reporting
        the problem and to Anders Wallin and Pat Rankin for help
        tracing and reproducing the problem and testing the fix.

Fri Sep  9 15:06:07 2005  Arnold D. Robbins  <arnold@skeeve.com>

        * hard-locale.h (xmalloc): Move declaration to file scope
        for non-glibc systems and gcc 4. Thanks to Kito Danya Dietrich
        <kito@gentoo.org>.

Thu Aug 25 22:40:40 2005  Arnold D. Robbins  <arnold@skeeve.com>

        * regcomp.c (build_range_exp): Avoid `btowc' for single-byte
        characters. Fedora Core 2, maybe others, have a broken version
        that can't handle values > 127.

Fri Aug 19 16:13:28 2005  Arnold D. Robbins  <arnold@skeeve.com>

        * regexec.c (proceed_next_node): Added a band-aid check at the
        top of the first `if' to make sure that `mctx->state_log[*pidx]'
        isn't NULL.

Fri Aug 12 13:10:33 2005  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (iop_alloc): Only free `iop' if it was malloc'ed in
        the first place.

Tue Jul 26 21:46:16 2005  Arnold D. Robbins  <arnold@skeeve.com>

        * Release 3.1.5: Release tar file made.

        Copyright dates on all relevant files updated to 2005.

Wed Jul  6 17:09:02 2005  Arnold D. Robbins  <arnold@skeeve.com>

        Minor cleanups:

        * io.c (do_index): Remove unused variables `mbclen', `mbs1' and `mbs2'.
        * node.c (wstrstr): Remove unsed variable `j'.
        (dump_wstr): `#ifdef' out, not currently needed.
        * eval.c (op_assign): Move decl of `t1' and `t2' into a separate block
        for the `! HAVE_FMOD' case. Keeps the compiler quiet. Similar for
        `ltemp'.

Wed Jul  6 16:51:31 2005  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (close_io): Now takes pointer to boolean parameter indicating
        if there was a problem closing standard output or standard error.
        Update it in the right places.
        * awk.h (close_io): Update the declaration.
        * main.c (main): New variable `stdio_problem'. Pass it to `close_io'.
        Check the result and exit non-zero if there was a problem.
        (usage, version): Print warning message if problems with stdout.

        Unrelated:

        * main.c (main): For call to `setlocale' for LC_MESSAGES, just use
        `#ifdef LC_MESSAGES'.  Per Bruno Haible <bruno@clisp.org>.

Wed Jul  6 16:44:58 2005  Jim Meyering  <jim@meyering.net>

        * main.c (init_fds): If any of the STDIN_FILENO, STDOUT_FILENO,
        STDERR_FILENO are initially closed, reopen them with permissions
        contrary to common usage so that any reasonable attempt to use
        them will evoke the same sort of error as reading or writing to
        a closed file descriptor would.

        * regex_internal.c (build_wcs_upper_buffer): Label `offsets_needed'
        should not be inside `#ifdef _LIBC'.
        * regcomp.c (build_charclass): Fix declaration of `class_name' in
        prototype to not be unsigned.

Thu Jun 30 11:52:34 2005  Arnold D. Robbins  <arnold@skeeve.com>

        * profile.c (tree_eval): Node_not: Remember to print the exclamation
        point!  Thanks to Dan Nielsen <Dan.Nielsen@corporate.ge.com>
        for the bug report.
        * mbsupport.h: Fix spelling of HAVE_ISWUPPER. Thanks to
        Kimura Koichi, <kimura.koichi@canon.co.jp>.

        Unrelated changes:

        * builtin.c (do_length): Allow array argument to length().
        Returns number of elements in array.

        * awkgram.y (yylex): Ignore carriage returns in source code. Sigh.

        * node.c (isnondecimal): Check loc.decimal_point before using it.
        Avoids problems with command line assignment when locale info may
        not be set up all the way yet.

Wed Jun 15 21:59:54 2005  Arnold D. Robbins    <arnold@skeeve.com>

        * node.c (make_str_node): If working with multibyte characters, while
        parsing string constants, keep multibyte characters together. This
        avoids problems in cases where one of the bytes is backslash. Initial
        patch supplied by Kimura Koichi, <kimura.koichi@canon.co.jp>.

Tue Jun 14 21:50:37 2005  Andrew J. Schorr     <ajschorr@users.sourceforge.net>

        Use Exponentiation By Squaring for integer powers for ^ and ^=.

        * eval.c (calc_exp, cal_exp_posint): New functions.
        (r_tree_eval): Use them.

Fri Jun  3 12:15:54 2005  Arnold D. Robbins    <arnold@skeeve.com>

        * configure.ac: Further change the hack at the end so that
        it works on Mac OS X `sed'. Sigh.

Thu Jun  2 22:44:01 2005  Arnold D. Robbins    <arnold@skeeve.com>

        * configure.ac (TYPE_SOCKLEN_T): Use `int' as default type if can't
        figure one out.
        * awkgram.y: Warn that `//' is not a C++ comment. (:-)

Thu Jun  2 20:55:27 2005  Arnold D. Robbins    <arnold@skeeve.com>

        From: Benno Schulenberg <benno@nietvergeten.nl>

        * eval.c (func_call): Take message out of gettext call since it's for
        debugging.
        * ext.c (get_actual_argument): Fix formatting of message.

Wed May 25 09:19:37 2005  Arnold D. Robbins    <arnold@skeeve.com>

        * configure.ac: Change hack at end that fixes Makefile to keep
        version.c to use `sed' and not `ed'. More portable to OS/2, probably
        other systems.

Mon May 23 09:01:26 2005  Arnold D. Robbins    <arnold@skeeve.com>

        Portability help from Jim Meyering.

        * io.c: Rework ifdefs for <inttypes.h> and <stdint.h>. Test them
        individually.
        * configure.ac: Add AC_C_RESTRICT and code for socklen_t from rsync.
        Check for isascii and btowc for regex.

Sat May 14 22:49:54 2005  Arnold D. Robbins    <arnold@skeeve.com>

        * wait_any (errno): Remove decl.
        * gawk_popen: The pipe-simulated but not VMS or DOS version. Remove
        decl/use of `strdup' in favor of `emalloc' and `strcpy'.

Wed May 11 18:33:30 2005  Arnold D. Robbins    <arnold@skeeve.com>

        All files: Updated address of FSF to:

        51 Franklin Street, Fifth Floor
        Cambridge, MA  02110-1301

Wed May 11 18:19:03 2005  Jim Meyering  <jim@meyering.net>

        * configure.ac: Use AM_GNU_GETTEXT([external]).
        Reflect upgrade to gettext-0.14.4.
        Reflect renaming of `jm_'-prefixed macros.
        (AC_CONFIG_FILES): Remove intl/Makefile.

        * Makefile.am (SUBDIRS): Remove intl.
        (AM_CPPFLAGS): Remove -Iintl.

Wed May 11 11:42:06 2005  Arnold D. Robbins    <arnold@skeeve.com>

        Straighten out mess with `isblank' which is C99 <ctype.h> function.

        * configure.ac: Remove check for `isblank' in call to AC_CHECK_FUNCS.
        * regex_internal.h: #ifdef out definition of `isblank' and provide
        `is_blank' function a la dfa.c.
        * field.c: Ditto.
        * regcomp.c: #ifdef use of `isblank' and add `is_blank' use instead.

Mon May  9 08:29:37 2005  Arnold D. Robbins    <arnold@skeeve.com>

        * configure.ac: Add type check for `socklen_t', fixes compile
        warning on AMD/64 Linux.
        * io.c (socketopen): Change type of socket length variables
        to `socklen_t' from `size_t'.

Thu May  5 22:00:03 2005  John E. Haque <j.eh@mchsi.com>

        * io.c (iop_alloc): Let an input processor hook installed via
        `register_open_hooks' open its own fd in case gawk does not know
        how to open it.
        (iop_open): Call `os_close_on_exec' after `iop_alloc'.
        ADR: If `iop_alloc' returns NULL but the fd is valid, close
        the fd to avoid an fd leak.

Mon May  2 08:05:59 2005  Arnold D. Robbins    <arnold@skeeve.com>

        * eval.c (update_ERRNO): Don't use `return' in a `void' function.
        * awk.h (AWKNUM): Back out use of `long double' based on LDBL_MANT_DIG.
        * builtin.c (tmp_integer): Back out extra ifdefs.

Fri Apr 29 13:01:05 2005  Arnold D. Robbins    <arnold@skeeve.com>

        * configure.ac: Look for `isblank' function.
        * field.c: Add define for `isblank' if we don't have it.

Fri Apr 29 12:01:33 2005  Julian Foad  <julianfoad@btopenworld.com>

        From grep.  Doesn't seem to affect awk.

        * dfa.c (lex): Fix bug #9519: "echo do^re | grep do^re" was
        failing to find a match. [Towards end, set `lasttok' before
        returning `c'.]

Fri Apr 29 00:28:46 2005  Arnold D. Robbins    <arnold@skeeve.com>

        * configure.ac: Jump through an amazingly convoluted hoop to get
        config.status to keep version.c upon `make distclean'. Seems to
        work though.

Thu Apr 28 23:40:02 2005  Stepan Kasal  <kasal@ucw.cz>

        * configure.ac (PRINTF_HAS_F_FORMAT): Some cosmetic changes.
        (custom.h): Don't cat custom.h at the end of config.h; instead, use
        AH_BOTTOM([#include "custom.h"])
        * awklib/Makefile.am (AM_CPPFLAGS): Add $(top_srcdir) so that
        custom.h can be found.

Thu Apr 28 23:21:22 2005  Jim Meyering  <jim@meyering.net>

        * field.c (set_FIELDWIDTHS): Tighten up the code to accept FIELDWIDTHS
        values in [1..INT_MAX], e.g., detect overflow and invalid strings,
        and reject strings starting with `-'.

Thu Apr 28 23:05:33 2005  Stepan Kasal  <kasal@ucw.cz>

        * dfa.c (parse_bracket_exp_mb): Shorten one part of the code, to get
        closer to grep's copy.

Thu Apr 28 23:00:58 2005  Pat Rankin    <rankin@pactechdata.com>

        * builtin.c (format_tree) [#if VAXCRTL]:  For floating point
        formatting, reject zero_flag if using old VAXCRTL run-time
        library to avoid getting erroneous results which appear as if
        numerically incorrect (due to an embedded space in some cases,
        extra trailing zeroes in others) rather than just misformatted.
        `hsprint' test still fails, but not as badly.

Thu Apr 28 19:12:03 2005  Arnold D. Robbins    <arnold@skeeve.com>

        * re.c (reflags2str): Add three new RE_ flags from current regex.h
        to bring the table up to date.

        * builtin.c (format_tree): Save 2 spare bytes instead of one. Suggested
        by Stepan Kasal.

Thu Apr 28 18:16:09 2005  Andrew J. Schorr     <ajschorr@users.sourceforge.net>

        * awk.h (IOBUF): Add new fields `opaque', `get_record', and
        *close_func', to support insertion of an alternate input processor.
        This is used by the XML extension.
        (register_deferred_variable, register_open_hook, update_ERRNO_saved):
        Declare new functions.
        (load_environ, load_procinfo): Remove declarations -- these functions
        are no longer global, since we use register_deferred_variable instead.
        * awkgram.y (register_deferred_variable): New function to allow
        calling code to register special variable names that trigger a callback
        upon the first reference.  This is now used to implement ENVIRON
        and PROCINFO.
        (variable): Search the list of deferred variables instead of hardcoded
        tests for ENVIRON and PROCINFO.
        * eval.c (set_BINMODE): Fix spelling of "arbitrary" in warning message.
        (update_ERRNO_saved): New function that allows the caller to specify
        the errno value instead of using the current value.
        (update_ERRNO): Implement by calling update_ERRNO_saved(errno).
        * io.c (iop_close): Call `iop->close_func' if non-NULL.
        (close_redir): Should save `errno' value, otherwise `lintwarn' messages
        might update it.  Then use `update_ERRNO_saved' to set ERRNO.
        (do_getline): Call `update_ERRNO_saved' to set ERRNO based on the
        error code returned by the redirect function (instead of the current
        value of errno).  Similarly, use `update_ERRNO_saved' to set ERRNO
        based on the value returned by `get_a_record'.  But add a special
        check to avoid updating ERRNO if `get_a_record' returns an error
        code value of -1 (this is used by the XML extension which already
        sets ERRNO before returning).
        (register_open_hook): New function to register a function to be
        called whenever a new data file is opened.  This can be used to
        install a special input processor (as in the XML extension).
        (iop_alloc): Call registered open hook.
        (get_a_record): If a `get_record' method has been set, call that instead.
        * main.c (init_vars): Use `register_deferred_variable' to implement
        ENVIRON and PROCINFO.
        (load_environ, load_procinfo): Now static instead of global.
        * doc/gawk.texi: Document new internal functions `update_ERRNO_saved',
        `register_deferred_variable', and `register_open_hook'.

Thu Apr 28 10:50:10 2005  Arnold D. Robbins    <arnold@skeeve.com>

        * array.c (assoc_find, do_delete): Change incorrect uses of STREQN
        to memcmp.
        * builtin.c (do_index): Same.
        * field.c (set_FS): Same.
        * io.c (redirect, getredirect, do_close, set_RS): Same.
        * re.c (reisstring): Same.

Wed Apr 27 21:35:57 2005  Arnold D. Robbins    <arnold@skeeve.com>

        Allow for long double. Initial changes from  Jean-Marc Saffroy
        <jean-marc.saffroy@ext.bull.net>.

        * awk.h (AWKNUM): If have long doubles (LDBL_MANT_DIG), define AWKNUM
        as long double, otherwise just use double.
        * builtin.c (format_tree): Change type of tmpval to double.
        (do_strtonum): Same for `d' and types used in casts.
        (tmp_integer): Don't do bit shifting if have long doubles.

        Unrelated, from Andrew J. Schorr:

        * io.c (close_one): Check for RED_FILE|RED_WRITE, not just RED_FILE.

Mon Apr 25 12:23:18 2005   Andrew J. Schorr     <aschorr@telemetry-investments.com>

        * eval.c (r_tree_eval): In Node_assign_concat case, when copying string
        constants, include the terminating zero byte.

Fri Apr  1 06:26:31 2005   Arnold D. Robbins    <arnold@skeeve.com>

        Update to Automake 1.9.5.

        * INSTALL, aclocal.m4, depcomp, install-sh, missing,
        mkinstalldirs, ylwrap: Updated.

        Unrelated:

        * builtin.c (do_tolower, do_toupper): Remove old code
        based on 8-bit character table.

Wed Feb 23 08:23:22 2005   Arnold D. Robbins    <arnold@skeeve.com>

        * bisonfix.awk: New file, fixes continued #ifdef for dumb compilers.
        * Makefile.am (awkgram.c): Fix rule to use it.
        (EXTRA_DIST): Include bisonfix.awk.

Tue Feb 22 21:18:50 2005   Arnold D. Robbins    <arnold@skeeve.com>

        * random.h: Remove include of config.h and move it to ...
        * random.c: Here.  Move include of random.h back to where it was.

        * regcomp.c, regex.c, regexec.c: NUKED all use of alloca not inside
        `_LIBC' ifdef. Hooray!

Sat Feb 19 20:13:28 2005   Pat Rankin    <rankin@pactechdata.com>

        Workarounds for bugs and missing C89 features in old VAX C compiler.

        * regex_internal.h "mbsupport.h": Suppress inclusion if NO_MBSUPPORT
          is defined.
        [MB_CUR_MAX]: Define as 1 if mbsupport.h hasn't defined it.
        [ER_ERRMSG, ERRMSG_TYPE, ERRMSG_OFFSET, ERRMSG_SEPARATOR]: New macros
          conditionalized upon gawk's NO_TOKEN_PASTING macro.
        * regcomp.c: Use them.
        (parse_dup_op): Use alternate initialization of start_token if
          RE_TOKEN_INIT_BUG is defined.
        * regexec.c (proceed_next_node): Compare push_fail_stack() result
          explicitly against REG_NOERROR rather than implicitly against 0.

Sat Feb 19 20:05:50 2005   Pat Rankin    <rankin@pactechdata.com>

        * dfa.c "mbsupport.h": Suppress inclusion if NO_MBSUPPORT is defined.

Wed Feb 16 20:43:07 2005   Pat Rankin    <rankin@pactechdata.com>

        * awk.h "mbsupport.h": Suppress inclusion if NO_MBSUPPORT is defined.

        * random.c "random.h": Include this first to get config.h setup.
          <fcntl.h>: Guard inclusion with HAVE_FCNTL_H.
          <unistd.h>: Guard inclusion with HAVE_UNISTD_H.
        * io.c [#if defined(MSDOS) ||... defined(__CYGWIN__)]: Splice the
          backslash continuation back into one long line.

Wed Feb 16 10:11:21 2005   Arnold D. Robbins    <arnold@skeeve.com>

        * node.c (unref, format_val): Add assertions checking that both
        `tmp->wstptr != NULL' and `(tmp->flags & WSTRCUR) != 0' before
        freeing `tmp->wstptr'. Thanks to kimura.koichi@canon.co.jp.

        * random.c (HAVE_UNISTD_H): Conditionalize include of <unistd.h>.
        Thanks to Scott Deifik <scottd@amgen.com>.

Sun Feb 13 18:24:50 2005   Arnold D. Robbins    <arnold@skeeve.com>

        * io.c (socketopen): Move `#ifdef MSG_PEEK' up to above
        declarations too.  Thanks to Michal Jaegermann.

        * config.guess, config.sub: Updated from Savannah.

Thu Feb 10 15:48:48 2005   Arnold D. Robbins    <arnold@skeeve.com>

        * regex_internal.c (re_dfa_add_node): Remove variable `type'
        and just use `token.type' directly in RE_ENABLE_I18N code below.
        Saves a compiler warning, and a good compiler will handle it anyway.
        * regexec.c (check_arrival_add_next_nodes): Move decl of `err'
        inside #ifdef RE_ENABLE_I18N code where it's used.
        * awkgram.y (yylex): Add casts to int before use of `strlen' results
        for printf-style precision. Avoid a compiler warning.

        Thanks to Michal Jaegermann <michal@harddata.com>.

Wed Feb  9 10:19:15 2005   Stepan Kasal  <kasal@ucw.cz>

        * Makefile.am (datadir, libexecdir): Removed.
        (awkdatadir): Renamed to pkgdatadir.
        (pkgdatadir, LDADD): Use the make syntax to refer to other variables,
        not @...@.

Wed Feb  9 10:05:46 2005   Arnold D. Robbins    <arnold@skeeve.com>

        * node.c (r_dupnode): Assign NULL to r->wstr after `getnode'.
        Fix count of bytes to copy in call to `memcpy'.
        Thanks to Kimura Koichi, <kimura.koichi@canon.co.jp>.

Tue Feb  8 19:26:22 2005   Pat Rankin  <rankin@pactechdata.com>

        * regcomp.c (init_dfa): Avoid strcasecmp() since regex.c doesn't
        use awk.h and none of the assorted other included header files
        are guaranteed to declare it.
        (parse_expression): Modify casts for the string arguments passed to
        build_charclass_op() to fix char * vs unsigned char * mismatch.
        (parse_bracket_exp): Likewise add cast for the string argument
        passed to build_charclass().

Mon Feb  7 15:04:09 2005   Arnold D. Robbins    <arnold@skeeve.com>

        * eval.c (make_scalar): Don't use P() macro in definition.

Wed Feb  2 16:36:19 2005   Arnold D. Robbins    <arnold@skeeve.com>

        * main.c (main):  Call `close_io', without its result affecting
        the exit status.  Super small, super dark corner.

        See test/exitval2.awk.

Tue Feb  1 11:58:29 2005   Arnold D. Robbins    <arnold@skeeve.com>

        * regex.h (__APPLE_CC__): Removed test and definition of __restrict.
        Not needed for current MacOS X compiler.

Sun Jan 30 13:56:37 2005   Arnold D. Robbins    <arnold@skeeve.com>

        Fresh merge with CVS regex routines. Fixes handling of \B.

Sat Jan 22 22:30:40 2005   Arnold D. Robbins    <arnold@skeeve.com>

        Reinstate patch of 18 Nov 2001, for VMS, at least:

        * random.c (srandomdev): ifdef-out.  Lots of compile time
          problems on multiple platforms, and gawk doesn't even
          use the routine.  The heck with fine-grained solutions.

Thu Jan 20 14:15:32 2005   Arnold D. Robbins    <arnold@skeeve.com>

        * awkgram.y (LEX_FOR): Free NAME tokens in transformation of
        `for (iggy in foo) delete foo[iggy]' into `delete foo'.
        Thanks and a tip of the hatlo to Valgrind.

        * dfa.c (_): Clean up stuff here by just including "gettext.h".
        Per Bruno Haible.

Wed Jan 19 18:29:23 2005   Arnold D. Robbins    <arnold@skeeve.com>

        * awkgram.y (yylex): Improve parsing of numeric constants
        and hex values, via a push from Paul Eggert. See test/hex.awk.

        * regex_internal.c (re_node_set_alloc): If `size' is 0, just
        zero out the structure. From valgrind.

Tue Jan 18 17:23:25 2005   Arnold D. Robbins    <arnold@skeeve.com>

        Make gawk multibyte aware.  This means that index(), length(),
        substr() and match() all work in terms of characters, not bytes.

        * awk.h (NODE): Add `wsp' and `wslen' elements to value for wide
        string.
        (WSTRCUR, wstptr, wstlen, force_wstring): New macros.
        (str2wstr, wstrstr, wcasestrstr): New declarations.
        * builtin.c (do_index, do_length, do_substr, do_match): Handle wide
        strings.
        * eval.c (flags2str): Add WSTRCUR.
        * node.c (format_val, r_dupnode, mk_number, make_str_node, unref):
        Add code to deal with wide strings.
        (str2wstr, dump_wstr, wstrstr, wcasestrstr): New functions.

Sun Jan 16 15:10:35 2005   Arnold D. Robbins    <arnold@skeeve.com>

        * random.h (int32_t): Define this type.

Thu Jan 13 14:38:13 2005   Arnold D. Robbins    <arnold@skeeve.com>

        Cause `configure --disable-nls' to still allow locale-correct
        formating of numeric values.

        * builtin.c (format_tree): Change #ifdefs to only test HAVE_LOCALE_H.
        Improve code for ' flag so that extraneous separator is not included if
        number of digits is multiple of locale separater count (3, 6, 9, etc.)
        * dfa.c (dfaparse): Change ifdef to only test #ifdef LC_COLLATE.
        * eval.c (fmt_ok): Remove ENABLE_NLS from #ifdef test.
        * gettext.h: Include <locale.h> on both sides of test. Should really
        be factored out.
        * main.c (loc): Remove ENABLE_NLS from #ifdef test.
        (main): Same in call to localeconv().
        * node.c (isnondecimal): Remove ENABLE_NLS from #ifdef test.

        Unrelated:

        * regcomp.c (init_dfa): Change `codeset' to `codeset_name' in two
        places.

        install-sh, missing, ylwrap: Updated.

Mon Jan  3 11:23:36 2005   Arnold D. Robbins    <arnold@skeeve.com>

        Fix obscure issue. ^ in RS should only match at the very
        beginning of the input.  Essentially, the file is one long
        string.  To do this, use the `not_bol' flag in the `struct
        pattern_buffer'.  Thanks to Stepan Kasal for pointing out the
        problem and to Andreas Schwab for pointing out the mechanism
        for a solution.

        * awk.h (RE_NEED_START, RE_NO_BOL): New flags for `research'.
        (IOP_AT_START): New flag for IOBUF.
        (research): Last parameter is now `flags'.
        * builtin.c (do_match, sub_common): Change calls to `research'.
        * eval.c (interpret, match_op): Same.
        * field.c (re_parse_field): Same.
        * io.c (spec_setup): Add IOP_AT_START flag.
        (iop_alloc): Same.
        (rsrescan): Modify logic to check IOP_AT_START and if not on to
        add RE_NO_BOL to flags value in call to `research'.
        (get_a_record): Clear IOP_AT_START upon return from `*matchrec'.
        (iopflags2str): Add IOP_AT_START to table.  Also IOP_CLOSED,
        which was missing. (Ooops.)
        * re.c (research): Last paramater is now flags.  Modify logic to
        handle RE_NO_BOL case by setting the right bit initially. Clean
        up control flow so that it's cleared before returning.  If RE_NO_BOL,
        don't bother with the dfa matcher, as it doesn't have an analogous
        capability.

Wed Dec 22 12:33:48 2004   Arnold D. Robbins    <arnold@skeeve.com>

        For --exec, don't allow x=y assignments where filenames would be.
        Do allow -v.  This is because we assume --exec is used mainly for
        CGI stuff and we don't want var assigns to affect the code.

        Suggested by Stepan Kasal; motivated by reading about web security.

        * main.c (disallow_var_assigns): New variable.
        (main): Set the var for --exec.
        (arg_assign): Check it appropriately.

Sun Dec 19 17:27:09 2004   Arnold D. Robbins    <arnold@skeeve.com>

        * builtin.c (do_gensub): Make `global' flag smarter, such that
        a string numeric constant (e.g., "3") acts like a numeric
        constant.
        * node.c (r_force_number): Not really related: Only set NUMCUR
        if we actually convert some digits.

Sun Dec 19 16:08:50 2004   Arnold D. Robbins    <arnold@skeeve.com>

        * dfa.h, dfa.c: Synchronize with what's happening in GNU grep
        development.  Effectively only minor whitespace changes and some
        slight code motion of ifdefs and includes.
        * hard-locale.h: New file, extracted from old dfa.c.
        * Makefile.am (base_sources): Add hard-locale.h.

Sun Dec 19 11:13:45 2004   Arnold D. Robbins    <arnold@skeeve.com>

        * io.c (socketopen): Change type of `readle' and `namelen'
        variables to size_t.  For QNX, but a good idea anyway. Thanks
        to `Anthony' (rz1a@mail.ru).

Mon Dec  6 11:11:22 2004   Arnold D. Robbins    <arnold@skeeve.com>

        Undid change of Mar 9 2004, to add gofast patch.  It gets things
        wrong for gawk.  This removes the bandaid of ifdef-ing out the
        main check.  Eventually this'll all get straightened out in the
        GNU grep code.

        * dfa.c (buf_offset): Removed.
        (SKIP_REMAINS_MB_IF_INITIAL_STATE): Removed use of buf_offset, do
        free `mblen_buf', `inputwcs'.
        (match_anychar, match_mb_charset, transit_state_consume_1char,
        transit_state): Remove use of buf_offset in mblen_buf.
        (dfaexec): Use `free' and `malloc', not `realloc'.

Mon Dec  6 10:55:37 2004   Fumitoshi UKAI       <ukai@debian.or.jp>

        Forwarded from james@nocrew.org, the Debian contact.

        * dfa.c (parse_bracket_exp_mb): 
        1. Build range correctly when IGNORECASE for [a-a] to also get 'A'.
        2. For [:lower:] and [:upper:], if ignoring case, set type string
           to "alpha".  This parallels code in the regex routines.
        3. Reset wc1 to EOF when parsing bracket expressions.

Mon Nov 29 18:36:25 2004   Arnold D. Robbins    <arnold@skeeve.com>

        * io.c (redirect): When allocating a new struct redirect, set
        rp->pid to -1, not 0, so that code checking for EOF on an
        input pipe works correctly.

Thu Nov 25 14:22:41 2004  Stepan Kasal  <kasal@ucw.cz>

        * Makefile.am (MAINTAINERCLEANFILES): Add.
        * version.in (version_string): Use PACKAGE_STRING.

Tue Nov 23 17:27:38 2004  Stepan Kasal  <kasal@ucw.cz>

        * re.c: Fix a typo in a comment.

Mon Nov 22 16:47:00 2004   Arnold D. Robbins    <arnold@skeeve.com>

        * awkgram.y (yylex): Add lint check for tawk style modifiers on
        regexes, /.../i and /.../s.  Not that it'll help anyone.

Wed Oct 27 14:25:18 2004  Stepan Kasal  <kasal@ucw.cz>

        * builtin.c (do_tolower, do_toupper): Fix the wide char handling,
          especially when the lowercased char doesn't ocuppy the same
          number of bytes as its uppercase equivalent.  Make use of ...
        (wide_tolower_toupper): ... this new static function.

Mon Oct 25 11:51:14 2004   Arnold D. Robbins    <arnold@skeeve.com>

        * builtin.c (bchunk, bchunk_one, cksize): Change type of `olen'
        to size_t from long.  It is the 21st century now, after all...
        Thanks to Stepan Kasal.

Mon Oct 11 10:49:09 2004   Arnold D. Robbins    <arnold@skeeve.com>

        * awkgram.y (yylex): Improve lint warnings for non-decimal constants.
        * node.c (isnondecimal): Made a little smarter, thanks to Stepan Kasal.

Thu Oct  7 21:59:38 2004   Arnold D. Robbins    <arnold@skeeve.com>

        * dfa.c (dfamust): Redo fix of 22 Sep to match code from
        current GNU grep.

Sun Oct  3 23:06:00 2004   Arnold D. Robbins    <arnold@skeeve.com>

        * node.c (isnondecimal): Made smarter, so that 0xEE does
        register as non-decimal. Added parameter to indicate use of
        locale's decimal point and changed declaration and callers.

Tue Sep 28 18:38:17 2004   Arnold D. Robbins    <arnold@skeeve.com>

        * node.c (isnondecimal): New function, now smarter.
        * awk.h (isnondecimal): Changed from macro to function.

Wed Sep 22 11:24:46 2004   Arnold D. Robbins    <arnold@skeeve.com>

        * dfa.c (dfamust): At end, check results of `malloc'.
        Based on bug report from Sorav Bansal <sbansal@stanford.edu>
        for grep.

Mon Sep 20 13:18:18 2004   Arnold D. Robbins    <arnold@skeeve.com>

        New --exec option.  Needed for gawk CGI scripts to prevent
        arbitrary options and/or source getting passed in from the web.

        * main.c (optab): New long option, --exec.
        (main): Catch it.  Like -f but end option processing.
        (usage): Add it to the usage message.

        Thanks to John DuBois and Don Stokes for their input.

        Unrelated:

        * dfa.c (dfaexec): Disabled caching into buffer that bypasses
        multibyte initialization, since it can get things wrong. Thanks
        to Andreas Schwab <schwab@suse.de>.

Mon Sep 20 12:59:42 2004   Andreas Schwab  <schwab@suse.de>

        * awkgram.y (nextc): Check for end of lexer buffer before
        advancing ring buffer index.

Wed Sep  8 09:54:53 2004   Arnold D. Robbins    <arnold@skeeve.com>

        * main.c (main): Force LC_NUMERIC locale to "C" before parsing
        the program, since a variable assignment with -v can leave the 
        locale set incorrectly.

        Thanks to Sirix <sirix@poczta.onet.pl> for reporting the problem.

Wed Aug 25 18:55:30 2004   Arnold D. Robbins    <arnold@skeeve.com>

        * main.c (UPDATE_YEAR): New constant at top of file, where we
        won't miss it.
        (copyleft): Use it.

Sun Aug 22 17:26:39 2004   Stepan Kasal  <kasal@ucw.cz>

        Define gawk_mb_cur_max even if there is no mbs support, as
        ``const int'' and assign 1 to it.
        This fixes a bug in re.c where #ifdef MBS_SUPPORT was missing.

        * awk.h (gawk_mb_cur_max): Declare.
        * main.c (gawk_mb_cur_max): Define.
        * awkgram.y (nextc_is_1stbyte): Without mbs support, define to 1.
        * builtin.c (index_multibyte_buffer): Define a dummy function
          when there is no mbs support.
        * awkgram.y, builtin.c, re.c: Remove some `#ifdef MBS_SUPPORT'.

Sun Aug 15 22:08:04 2004   Arnold D. Robbins    <arnold@skeeve.com>

        Import current FreeBSD random.c.  Make it work for gawk.
        Needed for cases where long is more than 32 bits.

        * random.c: Imported from FreeBSD. Header includes tweaked.
        * random.h: Typdef gawk_uint32_t appropriately and #define uint32_t
          to it.
        * configure.ac: Add calls to AC_CHECK_SIZEOF for unsigned int
        and unsigned long.

        Started with
        http://www.freebsd.org/cgi/cvsweb.cgi/src/lib/libc/stdlib/random.c
        Thanks to Andreas Schwab <schwab@suse.de> for the pointer.

Thu Aug 12 13:09:53 2004   Arnold D. Robbins    <arnold@skeeve.com>

        * main.c (copyleft): Fix copyright year.

Mon Aug  2 12:18:15 2004   Arnold D. Robbins    <arnold@skeeve.com>

        * Release 3.1.4: Release tar file made.

Mon Aug  2 12:17:40 2004   Arnold D. Robbins    <arnold@skeeve.com>

        * configure.ac: Fix the hack. Do the sed on `Makefile',
        not `Makefile.in'.  Sigh.

Sun Aug  1 14:48:30 2004   Arnold D. Robbins    <arnold@skeeve.com>

        * configure.ac: MAJOR HACK: At end, remove version.c from Makefile.in
        variable `CONFIG_CLEAN_FILES' so that `make distclean' doesn't
        remove version.c.

Mon Jul 19 17:07:27 2004   Arnold D. Robbins    <arnold@skeeve.com>

        * config.guess, config.sub: Updated from Savannah CVS.

Fri Jul 16 10:59:07 2004   Arnold D. Robbins    <arnold@skeeve.com>

        * re.c (make_regexp): Bracket code using `gawk_mb_cur_max'
        inside `#ifdef MBS_SUPPORT'.

Thu Jul 15 12:36:25 2004   Arnold D. Robbins    <arnold@skeeve.com>

        * dfa.c (parse_bracket_exp_mb):  If doing case folding,
        include the other case for regular characters inside [...].

        * re.c (make_regexp): Smarten up handling of IGNORECASE,
        particularly for multibyte character sets. Sigh.

Wed Jul 14 16:25:23 2004  John Haque  <mary1john8@earthlink.net>

        * eval.c (interpret): For `Node_K_return', use `copynode'
        and not `dupnode' for non-PERM, non-TEMP values.
        (func_call): Don't add TEMP flag to returned value.

        These two fix a problem uncovered by the July 8 change in
        `assoc_lookup'.

Wed Jul 14 16:14:09 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y (node_common): Add check `lexeme >= lexptr_begin',
        from valgrind run.

Wed Jul 14 16:00:51 2004  John Haque  <mary1john8@earthlink.net>

        * io.c (rsrescan): Fix off by one error at end of record.

Thu Jul  8 16:59:51 2004  Stepan Kasal  <kasal@ucw.cz>

        * awkgram.y (output_redir): Make sure not to dereference NULL
          pointer.  The bug was triggered by the following code:

                gawk 'BEGIN{print "date" |& getline}'

        No test case created, beacuse of the following:
        Correct interpretation involves executing "1" or "0" -- as the user
        may have defined this, we would have to override this in the test
        script.  It's not worth the hassle.

Thu Jul  8 12:59:49 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * awk.h (load_casetable): Name changed from `load_ignorecase'.
        * eval.c (load_casetable): Name changed from `load_ignorecase'.
        Fix all uses.

Thu Jul  8 12:32:13 2004  John Haque  <mary1john8@earthlink.net>

        * awkgram.y (get_src_buf): Fix off-by-one error to avoid "does not end
        in newline" messages.
        * array.c (assoc_lookup): Small performance hack: for TEMP subs nodes,
        use its string memory for ahname.
        * ext.c (get_actual_argument): Minor code cleanup.
        * builtin.c (do_lshift, do_rshift, do_and, do_or, do_xor, do_compl):
        fixed to issue "non-numeric argument" lint warnings before using
        `force_number'.

Mon Jun 21 16:53:35 2004  Arnold D. Robbins  <arnold@skeeve.com>

        More changes from John Haque to rationalize extension functions.

        * awk.h (get_curfunc_arg_count): Name changed from
        `get_curfunc_parm_count'.
        * eval.c (get_curfunc_arg_count): Ditto, body redone to count actual
        args passed at call time.
        * ext.c (get_argument): Update range check.
        (get_actual_argument): Simplify the code.

Mon Jun 14 14:01:16 2004  Arnold D. Robbins  <arnold@skeeve.com>

        Changes from John Haque and ADR to rationalize extension functions.

        new function declarations.
        (get_scalar_argument, get_array_argument): New macros.
        * awkgram.y (check_special): New function.
        (yylex): Use `check_special' to search `tokentab'.
        (dump_funcs): Always count functions, in order to get dynamic ones.
        Removed bogus use of `static' on `tab' variable.
        * eval.c (struct fcall): Change type of `count' to `size_t'.
        (get_curfunc_parm_count): New function.
        (push_args): Set `r->rnode' to NULL for local variable.
        * ext.c (make_builtin): Add sanity checking for presence and
        name of new function, and that it's not a redefinition.
        (get_argument): Check that requested arg is within range of actual
        number of parameters.  Also clean up logic for Node_var_new,
        Node_var_array, Node_array_ref.
        (get_actual_argument): New function.
        * profile.c (pp_builtin): Better handling of dynamic extension function.

Sun Jun 13 14:32:22 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (redirect): Conditionalize checking for process recovery
        on `#ifdef PIPES_SIMULATED'.  Needed for MS-DOS and VMS.
        * builtin.c (tmp_integer): Change bracketing of magic test to
        `#ifdef HAVE_UINTMAX_T' which is more general and more correct.

Wed Jun  9 21:36:01 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * re.c (make_regexp): Add dfa matching into IGNORECASE handling.

        * awk.h (casetable): Remove `const'.
        * eval.c (casetable): Remove `const'.
        (load_ignorecase): New function.  Loads locale-correct values in
        upper 128 bytes.
        (set_IGNORECASE): Call `load_ignorecase'.

Tue Jun  8 14:04:19 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y (get_src_buf): Make sure that value from
        `optimal_bufsize' is reasonable.  Increase it if not.

Tue Jun  8 13:54:28 2004  John E. Haque      <mary1john8@earthlink.net>

        * awkgram.y (statement:LEX_FOR): Fix bug in loop to `delete a'
        optimization.
        * io.c (format_tree): Check for out of range values for
        positional specifiers.

Mon Jun  7 17:02:48 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (tmp_integer): Bracket the magic test inside
        `#ifndef VMS'.

        * awk.h (child_catcher): Remove declaration.
        * main.c (main): Remove `signal' calls for SIGCLD, SIGCHLD.
        * io.c (child_died, child_signo, child_catcher): Removed.
        (get_a_record): Remove code checking for death of child.
        (redirect): If `rp' matches and is at EOF and type is input
        pipe, and `rp->pid' is not -1, call `wait_any' to reap the
        child.  This is a heuristic, but it works pretty well.

Sun Jun  6 18:35:17 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (get_a_record): Restore use of `memmove' instead of
        memcpy. Otherwise some tests break on some systems. We think.
        (child_died): Don't reset signal handler; breaks on some S5 systems.
        (get_a_record): Reset handler if child_died. Still flaky on Solaris.
        * configure.ac (version.c): Made from version.in again, for
        non-Unix systems.
        * Makefile.am (base_sources): Add version.c back.
        * version.in: Include config.h for definition of const.
        * main.c (version_string): Add back declaration, don't
        include "version.i".
        (main): Don't install child_catcher on Sun. (HACK)

Thu Jun  3 14:06:06 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * main.c (version_string): Removed declaration, since
        version.i is included directly.
        * version.in: Removed test for definition of const.

Tue Jun  1 19:23:53 2004  Stepan Kasal  <kasal@ucw.cz>

        * Makefile.am (base_sources): Don't mention version.c, so that
        it doesn't get distributed.
        * po/POTFILES.in: Remove version.c
        * configure.ac: Create version.i from version.in.
        * main.c: Include version.i.

Tue Jun  1 18:33:32 2004  Arnold D. Robbins  <arnold@skeeve.com>

        Fix problem reported by Stephen Marchant <Stephen.Marchant@Cognex.com>
        on Thu, 30 Oct 2003 13:11:42 -0500.

        * regex_internal.h (re_realloc): Allow for SunOS pre-Standard C
        `realloc' which doesn't accept NULL pointers.
        * awk.h (erealloc): Same.

        Unrelated. Change suggested by Peter Sobisch <petersob@gmx.net>, have
        PROCINFO["version"] be the version of gawk:

        * main.c (load_procinfo): Add in version.

        Unrelated: Avoid warning:

        * main.c (main): Cast calls to `bindtextdomain' and `textdomain' to
        void.  Avoids diagnostic with `configure --disable-nls'.
        * dfa.c (check_matching_with_multibyte_ops): Remove unneeded nested
        #ifdef, per Scott Deifik (scottd@amgen.com).  Also fix some spelling
        errors in comments.

Tue Jun  1 18:26:45 2004  Paul Eggert  <eggert@twinsun.com>

        Fix a bug reported by Mike Romaniw <msr@micromonumental.com>
        to bug-gnu-utils on 2003-09-27: compl(compl(0xf0f)) returned 0xfff
        on hosts with 64-bit uintmax_t and 64-bit IEEE-764 double, due to
        rounding errors.

        * doc/gawk.texi (Bitwise Functions): Leading nonzero bits are
        removed in order to fit the result into a C 'double' without rounding
        error.
        * builtin.c: Include <float.h> if available.
        (FLT_RADIX, FLT_MANT_DIG, DBL_MANT_DIG): Define if not already defined.
        (AWKSMALL_MANT_DIG, AWKNUM_MANT_DIG, AWKNUM_FRACTION_BITS): New macros.
        (tmp_integer): New function.
        (do_lshift, do_rshift, do_and, do_or, do_xor, do_compl): Use them.

Tue Jun  1 17:40:47 2004  Stepan Kasal  <kasal@ucw.cz>

        * eval.c (push_args): Set var_value to Nnull_string for
        local variables.

Mon May 31 11:49:20 2004  Stepan Kasal  <kasal@ucw.cz>

        * replace.c: #undef DEBUG before including mktime.c, it has
          different meaning there.

Mon May 31 08:25:30 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * array.c (get_actual): Add extra error message for `delete f'
        inside body of function `f'.

Mon May  3 09:53:34 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * Makefile.in, */Makefile.in: Updated to automake 1.8.4.
        * config.guess, config.sub: Same.
        * aclocal.m4, depcomp, install-sh: Same.

Mon May  3 09:24:45 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * configure.ac: Look for missing `strtoul'.
        * replace.c: Include missing_d/stroul.c if not HAVE_STRTOUL.
        * io.c (devopen): Use `strtoul' instead of `strtod' for
          extracting fd number from "/dev/fd/N".  (Thanks to Jim Meyering.)
        * field.c (set_FIELDWIDTHS): Use `strtoul' instead of `strtod'
          when parsing FIELDWIDTHS values.  (Thanks to Jim Meyering.)

Mon Apr 19 20:12:57 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * Makefile.in, */Makefile.in: Updated to automake 1.8.3.
        * config.guess, config.sub: Same.

2004-03-18  Stepan Kasal  <kasal@ucw.cz>

        * eval.c (make_scalar): Comment clarification.

        * array.c (get_actual): Remove the condition ``canfatal''
          before ``cant_happen()''; if the data are consistent, we
          simply cannot get there with a non-func Node_param_list,
          no matter whether we are called via get_array or not.

        * awkgram.y (variable): Make one longer message, to help translators.

Tue Mar  9 17:34:10 2004  Arnold D. Robbins  <arnold@skeeve.com>

        Adapted `gofast' patch from Redhat Enterprise version of grep
        to current dfa.c.

        * dfa.c (buf_offset): New variable.
        (SKIP_REMAINS_MB_IF_INITIAL_STATE): Modified to use it, don't
        free `mblen_buf', `inputwcs'.
        (match_anychar, match_mb_charset, transit_state_consume_1char,
        transit_state): Use buf_offset in mblen_buf.
        (dfaexec): Realloc things instead of free and malloc.

Thu Mar  4 16:46:55 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * configure.ac (AC_FUNC_MBRTOWC): Added.
        (AC_CHECK_FUNCS): Removed `mbrtwoc'.
        (REGEX_MALLOC): Removed. Not needed for new regex* routines.

        * re.c (research): Removed comment and check for return of -2
        since that was for old regex using alloca or REGEX_MALLOC.

Wed Mar  3 17:10:16 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (close_one): Don't close stdout or stderr; can happen if
        /dev/stdout or /dev/stderr are used in redirection and all the
        open files get used.

Sun Feb 29 12:17:37 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * regcomp.c (build_charclass, build_charclass_op): Change type of
        `class_name' parameter to `const char *' from `const unsigned char *'
        and adjust callers.

Thu Feb 26 15:20:22 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y (get_src_buf): Rewritten to better manage input and
        supplying newlines on command line programs.  Fixes problems reading
        source files on Cygwin.

        Unrelated fixes from mary1john8@earthlink.net:

        * node.c (format_val): For no malloc case, free s->stptr if necessary.
        * io.c (nextfile): Add missing call to `unref(FILENAME_node->var_value)'
        for no files case.
        (close_redir): Remove file from redirection list even if fp is
        stdout or stderr.

Tue Feb 24 12:11:34 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * regex_internal.c (build_wcs_upper_buffer): Enclose `offsets_needed'
        label in `#ifdef _LIBC' to silence `unused label' compiler warning.

Tue Feb 24 11:57:18 2004  Nelson H.F. Beebe  <beebe@math.utah.edu>

        * regcomp.c (parse_expression): Add cast to (unsigned char *) in calls
        to `build_charclass_op'.
        * regex_internal.c (build_wcs_buffer): Add cast to char* in call to
        `wcrtomb'.
        * regex_internal.h (bitset_not, bitset_merge, bitset_not_merge,
        bitset_mask, re_string_char_size_a, re_string_wchar_at,
        re_string_elem_size_at): Change to use prototypes.
        (re_string_char_size_at, re_string_wchar_at, re_string_elem_size_at):
        Declare as `internal_function'.

        * Makefile.am: Add rule to make .i files.  This assists in debugging.
        * awk.h (m_tree_eval): Add casts to NULL.  (Some compilers are just
        dumb. ADR)

Mon Feb 23 15:58:39 2004  Arnold D. Robbins  <arnold@skeeve.com>

        Clean up occupied process slots of children that have died:

        * awk.h (child_catcher): New function, declare it.
        * main.c (main): Catch SIGCHLD/SIGCLD with `child_catcher'.
        * io.c (child_died): New static variable.
        (child_catcher): New function, sets `child_died', reinstalls self
        as signal handler.
        (close_rp): New function: isolates actual fp/iop closing logic.
        (close_redir): Call `close_rp'.
        (get_a_record): Check `child_died' and call `wait_any(0)' if so.
        Add descriptive comment.

        Unrelated clean up:

        * eval.c (fcalls): Renamed from `fcall_list'. All uses changed.
        (pop_fcall, push_args, dump_fcall_stack): Adjusted to use indexing
        on `fcalls' instead of a pointer into it. Avoids hassles if `fcalls'
        is realloc-ed during recursive tree_evals. Thanks to BWK.

        * config.guess, config.sub: Updated from Savannah.

2004-02-19  gettextize  <bug-gnu-gettext@gnu.org>

        * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.14.1.

Wed Feb 18 12:40:09 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y (rule): Use `msg' not `warning' for `must have an
        an action part' message.  `warning' is wrong, since it's a real error.

Mon Feb 16 12:17:39 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * main.c, eval.c, builtin.c: Change test for `#ifdef HAVE_LOCALE_H'
        to `#if ENABLE_NLS && defined(HAVE_LOCALE_H)' so that builds with
        `configure --disable-nls' will actually work on non-glibc systems.

Thu Feb 12 02:05:34 2004  Stepan Kasal  <kasal@ucw.cz>

        Lots of misc changes from Stepan Kasal integrated.

        * array.c: Various variables and parameters of static functions
        changed from int to long, in order to prevent overflow.

        * eval.c (make_scalar): New function; takes care of everything
        that has to be done when a node of type Node_var_new or
        Node_array_ref changes to a scalar variable.
        (tree_eval, get_lhs): Call it.
        (tree_eval): From now on, tree_eval(NULL) doesn't work;
        it reports an internal error.
        * awk.h (m_tree_eval): Likewise for the two macro versions.
        * awkgram.y (statement): Make sure the Node_K_return's lnode is
        always the return value, never NULL.

        * Makefile.am (install-exec-hook, uninstall-links): Make use of
        $(VERSION).
        (INCLUDES): Renamed to AM_CPPFLAGS.
        (AM_CPPFLAGS): The file libintl.h is generated in the
        build subdirectory intl, not in the directory $(srcdir)/intl.
        (diffout): New target is an alias for ``make -C test diffout.''
        * awklib/Makefile.am (INCLUDES): Renamed to AM_CPPFLAGS.

        * README_d/README.hpux: Change the whitespace in the appended patch,
        so that it applies to the current source.
        * posix/gawkmisc.c: Change a tab to a space (needed for the above).

        Make version control more in the style of current autotools:

        * configure.ac: Remove obsolete versions of macros:
        AM_INIT_AUTOMAKE doesn't need any parameters.
        AC_OUTPUT shouldn't have any parameters either.
        Its parameters go to a new macro: AC_CONFIG_FILES.
        AC_CONFIG_HEADERS moved near the end of the file.
        * configure.ac: Add [version.c:version.in] to AC_CONFIG_FILES
        * version.in: Modify for autoconf substitutions.
        * version.c: Remove, it's generated at configure time now.
        * fixvers, patchlev.h, unsupported/tandem/ptchlvl.h: Nuke and ...
        * Makefile.am, main.c: ... forget them.

Mon Feb  9 12:57:00 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * awk.h builtin.c eval.c field.c (HUGE): Changed to `UNLIMITED'.
        Avoids possible conflict with constant in svid-mode math.h. Thanks to
        Roman.Putanowicz@iecn.u-nancy.fr for pointing out the problem.

Fri Feb  6 12:09:55 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * configure.ac: Check for `wctype', `wcscoll' and `iswctype'.
        * mbsupport.h: New file. Merges and centralizes testing for MBS support.
        * Makefile.am (base_sources): Add mbsupport.h to list.
        * dfa.c, dfa.h, awk.h (MBS_SUPPORT): Include "mbsupport.h" and use the
        test there.
        * regex_internal (RE_ENABLE_I18N): Same.

        * Makefile.am (CLEANFILES): Added.

Thu Feb  5 18:05:12 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * configure.ac (HAVE_WCTYPE_T): New test code added.
        * dfa.h (wctype_t): Define if system doesn't. Needed here too
        for other files that include dfa.h.
        * dfa.c (wctype_t): Define if system doesn't.
        (lex): Manually fill in arrays used for char class range testing
        so will work on c89 and older compilers.
        (parse_bracket_exp_mb): Split up an assignment to avoid type complaints.

        * main.c (main): When checking for `close_io' failure, only set
        `exit_val' to 1 if not already exiting.

        * regcomp.c (regerror): Remove use of mempcpy.  Generates too
        many compiler warnings.
        * configure.ac (AC_CHECK_FUNCS): Don't bother checking for it.

Wed Feb  4 17:34:47 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * getopt.h (__THROW): Only define it if C++. The __GNU_PREREQ
        macro is a major headache.

2004-02-02  Paolo Bonzini  <bonzini@gnu.org>

        * regexec.c (check_matching): Add P_MATCH_FIRST parameter.
        (re_search_internal): Pass new parameter to check_matching.
        (check_matching): Unless a parenthesized group is found at the
        beginning of the regexp, advance P_MATCH_FIRST until we entered
        a state different from the initial state.

Mon Feb  2 15:52:37 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * re.c (research): Change last param to re_search to pass
        NULL if `need_start' is false.  May give us a marginal speed gain.

Thu Jan 29 17:04:51 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (sub_common): Fix logic for `&' in replacement for
        multibyte case.  Simplify code a bit.

Tue Jan 20 10:41:45 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * configure.ac: Add check for `memmove'.
        * replace.c: Include missing_d/memmove.c if don't have `memmove'.

Sun Jan 18 12:01:29 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (sub_common): Add comment and support for 2001 POSIX
        behavior when --posix in effect.  The masses have been
        clamoring for this one.

2004-01-16  gettextize  <bug-gnu-gettext@gnu.org>

        * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.13.1.
        * intl/*: Updated to 0.13.1.

Fri Jan 16 08:16:38 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * getopt.h, getopt.c, getopt1.c: Synced to GLIBC version:
        getopt.c:       1.51
        getopt.h:       1.18
        getopt1.c:      1.9

Thu Jan 15 15:28:48 2004  Arnold D. Robbins  <arnold@skeeve.com>

        Here we go again:

        * regcomp.c, regex.h, regex.c, regex_internal.h, regex_internal.c,
        regexec.c: Sync to GLIBC version, but with bug fixes.  GLIBC
        CVS versions:

        regcomp.c: 1.76
        regexec.c: 1.55
        regex.c: 1.125
        regex.h: 1.30
        regex_internal.c: 1.39
        regex_internal.h: 1.45
        regexec.c: 1.55

        * acinclude.m4: Removed, not needed for automake 1.8.x.
        * configure.ac: Updated to autoconf 2.59.

        Everything else updated to automake 1.8x and autoconf 2.59.

Wed Jan 14 14:26:36 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * dfa.c, dfa.h: Updated manually with most of the changes in
        grep 2.5.1.  That version lost the ability to match newlines
        in the data, so the merge had to be done by hand.  Sigh.

2004-01-12  Paolo Bonzini  <bonzini@gnu.org>

        ALLOCA patch from
        http://sources.redhat.com/ml/libc-alpha/2004-01/msg00099.html
        added.

        * regcomp.c [_LIBC && !RE_ENABLE_I18N]:
        Drop code to support this, it is never true.
        (build_range_exp) [!_LIBC]: Do not create a range
        in MBCSET for a single-byte character set.
        (build_range_exp) [_LIBC]: Do not create a range
        in MBCSET for a single-byte character set without
        collation elements.
        (init_dfa): Do not conditionalize on _LIBC, it
        just makes the code less clear.
        (parse_bracket_exp): Use NON_MATCH variable in
        addition to "mbcset->non_match", not as an
        alternative.
        (build_charclass_op): Rename NOT parameter to
        NON_MATCH, use it instead of declaring a variable. 
        (parse_bracket_exp) [!_LIBC]: Pass NULL for MBCSET
        if the character set is single-byte.

Wed Jan  7 15:23:04 2004  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y (mk_rexp): Set n->re_cnt to 1. Makes reinstated
        dfa code actually take effect!  Don't know how I missed this.

        Unrelated: sync regex code to glibc.

        * regcomp.c, regex.h, regex.c, regex_internal.h, regex_internal.c,
        regexec.c: Sync to GLIBC version, but with bug fixes.  GLIBC
        CVS versions:

        regcomp.c: 1.74
        regex.c: 1.124
        regex.h: 1.30
        regex_internal.c: 1.39
        regex_internal.h: 1.43
        regexec.c: 1.55

        * regcomp.c (peek_token): Temporarily, we hope, disable \s and \S
        operators.  Too much trouble to document right now.
        * dfa.c (lex): Add code for \s and \S but disable it until
        next release.

Wed Dec 24 15:28:57 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * eval.c (r_tree_eval): For Node_assign_concat, add
        call `free_temp(r)'. Thanks to mary1john8@earthlink.net.

Mon Dec  1 10:25:52 2003  Arnold D. Robbins  <arnold@skeeve.com>

        CONSTVAL not needed if we test PERM instead. Thanks to
        mary1john8@earthlink.net. See test/concat3.awk.

        * awk.h [CONSTVAL]: Removed.
        * eval.c (flag2str): Removed CONSTVAL from table.
        (r_tree_eval): For Node_assign_concat, it's enough to check
        if l->flags has PERM clear.
        * awkgram.y (yylex): Removed use of CONSTVAL for YSTRING and YNUMBER.

Mon Nov  3 16:33:26 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y (get_src_buf): Replace `memmove' with `memcpy' for
        marginal portability gain to older systems.
        * io.c (get_a_record): Ditto.

Sun Nov  2 15:59:27 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * awk.h [CONSTVAL]: Renamed from `STRCONST'.
        * eval.c (flags2str): Fix in table.
        (r_tree_eval): For Node_assign_concat, check for the flag for
        both left and right hand sides.  Also add a `force_string' call
        for the right hand side and the left hand side.
        * awkgram.y (yylex): Change flag value for YSTRING and add use
        of flag for YNUMBER.

Wed Oct 29 14:23:29 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * awk.h [STRCONST]: New flag value.
        * eval.c (flags2str): Add it to table.
        (r_tree_eval): For Node_assign_concat, check for the flag so that
        we don't clobber string constants given:
                s = ""
                s = s something
        * awkgram.y (yylex): For YSTRING, set STRCONST flag.

Tue Oct 28 18:00:00 2003  Arnold D. Robbins  <arnold@skeeve.com>

        Force SUBSEP to always have a string value. Per bug report
        from mary1john8@earthlink.net.

        * awk.h (NODETYPE): New type, Node_SUBSEP.
        (set_SUBSEP): Add declaration.
        * awkgram.y (isnoeffect, isassignable): Add Node_SUBSPEP case.
        * array.c (set_SUBSEP): New function.
        * eval.c (nodetypes): Add Node_SUBSEP.
        (r_tree_eval, r_get_lhs): Add code for Node_SUBSEP.
        * main.c (varinit): Use Node_SUBSEP as type for SUBSEP.
        * profile.c (tree_eval, pp_lhs, is_scalar, prec_level): Handle
        Node_SUBSEP.

Tue Oct  7 09:26:33 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * awk.h (NODETYPE): New member `Node_assign_concat'.
        * awkgram.y (exp): Look for case of `x = x y' and if so, create a
        Node_assign_concat.
        * eval.c (interpret): Add case for Node_assign_concat.
        * profile.c (prec_level): Ditto.
        (tree_eval): Ditto.  For variables, call new function `vname' to
        print name; handles varname field for -v variables, which end up
        including the value.
        (vname): New function.

Wed Sep 24 17:32:31 2003  Arnold D. Robbins  <arnold@skeeve.com>

        Speed up `avoid_dfa' kludge, at least a little:

        * awk.h (struct Regexp): Add `has_anchor' member.  Make it and
        `dfa' member shorts; keeps space the same.
        * re.c (make_regexp): Set `has_anchor' member correctly.
        (avoid_dfa): Test for `has_anchor' member instead of searching
        for it each time.

Sun Sep 21 18:34:32 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (state): Only needs to be 256 bytes, initstate() can't
        use any more than that.  Well whadayaknow.
        (do_rand, do_srand): Call `setstate' after calling `initstate'.

Tue Sep 16 15:44:29 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * eval.c (interpret): For Node_K_switch, add kludge_need_start stuff
        as used in `match_op'.  Sigh.
        * re.c (make_regexp): Add `no_dfa' variable, which is true if
        GAWK_NO_DFA exists in the environment.  This enables run time
        testing of things with/without the dfa matcher.

Mon Sep 15 18:36:38 2003  Arnold D. Robbins  <arnold@skeeve.com>

        After much soul searching, reinstated old dfa code. The performance
        of the new regex is just disastrous.  Sigh.

        * awk.h (re_cnt): Reinstated old definition.
        (struct Regexp): Added `dfareg' and `dfa' members.
        (make_regexp): New last parameter in function, changed decl.
        (avoid_dfa): Added declaration.
        * awkgram.y (regexp, mk_rexp): Added use of `re_cnt'.  Fixed call
        to `make_regexp'.
        * Makefile.am: Add dfa.h and dfa.c.
        * eval.c (match_op): Complexified: added call to `avoid_dfa' and
        `kludge_need_start' variable where used to pass FALSE as last parameter
        of research().
        * field.c (set_FS): Fixed call to `make_regexp'.
        * io.c (get_a_record, set_RS): Fixed calls to `make_regexp'.
        * re.c (make_regexp): Added last paramter (`dfa') to function.
        Complexified the code.
        (re_update): Fixed call to `make_regexp'.
        (research): Complexified the code, added calls to dfa stuff.
        (dfaerror): New function.
        (re_update): Fixed call to `make_regexp'.
        (avoid_dfa): New function.

Tue Sep  9 15:57:38 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y (get_src_buf): Fix calculation of `offset' when shifting
        source lines around.  In general, improve handling of things when
        moving the source code line around.  What a mess this code is.

Mon Sep  8 19:08:55 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * eval.c (fmt_ok): Make provision for %F format and printf %'f flag
        here too.

2003-07-23  Christophe Bisiere  <bisiere@univ-tlse1.fr>  (tiny change)

        * posix/regex.h (RE_TRANSLATE_TYPE): Define it to "unsigned char,"
          to avoid problems at hosts with signed char.
        * posix/regexec.c (re_search_internal): Don't say
          "unsigned RE_TRANSLATE_TYPE."

Thu Aug 28 11:09:41 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (nextfile): Change use of variable `files' to make it
        clearer that it's a boolean flag.

Tue Aug 26 22:58:15 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (useropen): Add `defined (HAVE_GETGROUPS)' as first test
        in `#ifdef'.  Brings things in sync with same test in main.c and awk.h.

Tue Aug 26 22:49:37 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * dbug.h: New file.

        * array.c, awkgram.y, builtin.c, eval.c, ext.c, field.c, io.c,
        main.c, msg.c, node.c, profile.c, re.c: Converted to use
        Fred Fish's `dbug' library.  By default compiled out, thus
        not affecting speed.

        For the nonce, the `dbug' library itself is not shipped with
        gawk, since I expect no-one else but me to be using it.

Thu Aug 21 23:15:36 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y (numfiles): Change extern decl to long, to match what's
        in main.c.  Keeps things working on 64-bit systems.  Thanks to bug
        report from Jan Oravec <jan.oravec@6com.sk>.

Wed Aug 20 14:53:47 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * eval.c (genflags2str): Move test for out-of-space inside test
        for is the bit set.

Mon Aug 11 11:26:51 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * regcomp.c (parse_bracket_exp): If `build_charclass' fails, just pass
        its value on as the return value.

Sun Aug 10 16:59:14 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * regcomp.c (build_range_exp): Make sure we don't
        get WEOF on range characters.

Tue Aug  5 21:49:32 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * array.c (get_actual): In `case Node_param_list' add test for
        `&& (symbol->flags & FUNC) == 0' to the if.

Sun Jul 13 18:28:38 2003  Arnold D. Robbins  <arnold@skeeve.com>

        Further bug fix:

        * awkgram.y (variable): Give the new variable an lnode
        of Nnull_string if it's not an array, even if it is
        a Node_var_new.

Fri Jul 11 09:32:21 2003  Arnold D. Robbins  <arnold@skeeve.com>

        Bug fix:

        * eval.c (r_tree_eval): For Node_array_ref, set
        tree->orig_array->var_value to Nnull_string too.

        Unrelated i18n and POSIX change:

        * configure.ac: Add check for local printf supporting %F format.
        * awk.h (loc): New variable declaration.
        * main.c (loc): Defined.
        (main): Call `localeconv' to set loc.
        * io.c (format_tree): Add support for printf quote flag, %'d for
        decimal formats (not %e, %E), adds thousand separator into value.

2003-07-10  Paul Eggert  <eggert@twinsun.com>

        * io.c (two_way_open): If /bin/sh cannot be executed, exit
        with status 126 consistently.

Mon Jul  7 11:01:43 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * Release 3.1.3: Release tar file made.

Mon Jul  7 09:55:49 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * main.c (copyleft, usage): Make sure to fflush output fp. Per Jim
        Meyering, if error, exit non-zero.
        * ext.c (get_argument): Fix array paramater handling.

2003-07-06  Paul Eggert  <eggert@twinsun.com>

        * builtin.c (do_substr): Issue better diagnostics when
        d_substr and d_length are NaN, or when 0 < d_length < 1.
        Be careful when comparing double to SIZE_MAX, as
        the comparison might return the "wrong" answer when
        `(double) SIZE_MAX' is a number that is not equal to
        SIZE_MAX.
        (do_gensub): Watch out for HOW values that are out of range
        or are NaN.
        (do_dcngettext): dcngettext wants an argument of type
        unsigned long, not long, so use a value of that type.

Fri Jul  4 10:58:02 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * main.c (main): Make option letter 'D' fall through into default
        unknown case if not debugging. Let's us have just one version of
        `optlist'.

Thu Jun 26 15:25:57 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * array.c (get_actual): Undo Stepan Kasal change of 2003-06-17.
        See test/match2.awk.

Wed Jun 25 15:26:08 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (do_rand): Change calculation so that result
        obeys constraint:  0 <= N < 1.  This is per history and POSIX.
        Thanks to Nelson Beebe (beebe@math.utah.edu) for reporting
        this issue.

Mon Jun 23 15:13:39 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (rs1scan): Per advice from Bruno Haible, it's safe
        to skip the multibyte checking code if RS is '\n'. See
        the comment in the code.  Big performance improvement for
        multibyte locales.

2003-06-20  Stepan Kasal  <kasal@ucw.cz>

        * eval.c (comp_func): If memcmp returns 0, we have to compare
          the lengths.

2003-06-19  Stepan Kasal  <kasal@ucw.cz>

        * eval.c (interpret) <Node_K_arrayfor>: Use NULL, not 0, to
          initialize the variable list.
          (comp_func): Array indices no longer are string values,
          you have to use ahname_str, ahname_len.

Tue Jun 17 11:53:46 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * array.c (get_actual): Make check for isparam
        smarter: also check for FUNC flag.

2003-06-17  Stepan Kasal  <kasal@ucw.cz>

        * array.c (get_actual): Even if canfatal is FALSE, don't
          tolerate existence of things which can't happen.

Mon Jun 16 16:21:44 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * configure.ac: Removed m4/Makefile.
        * m4/Makefile.am: Removed.

2003-06-16  gettextize  <bug-gnu-gettext@gnu.org>

        * configure.ac (AC_OUTPUT): Add m4/Makefile.
        (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.

Sun Jun 15 20:45:43 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (get_a_record): Enhance logic to fill buffers to include
        `|| no_data_left(iop)'.
        (rs1scan): Fix logic for setting recm fields for multibyte
        character case.

2003-06-10  Stepan Kasal  <kasal@ucw.cz>

        * awkgram.y (release_all_vars): Do not try to release a value of
          Node_var_new; after get_lhs, use the lhs directly, do not try
          to do (*lhs)->var_value; the Node_var case doesn't need
          special treatment.
        * builtin.c (do_match): `get_param' is successful iff it returns
          Node_var_array---if the variable was new, get_param has already
          changed the type.
        * field.c (do_split): Likewise.

Sun Jun 15 19:36:35 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * node.c (r_dupnode): Typo fix in hash tables: stptr -> ahname_str.
        Thanks to mary1john8@earthlink.net.
        * array.c (get_actual): Add `if (canfatal)' before call to
        `cant_happen'.

Sun Jun 15 19:25:49 2003  Patrick T.J. McPhee   <ptjm@interlog.com>

        * awk.h (memcpy_ulong): Add ! WIN32 to ifdefs.

Mon Jun  9 18:38:20 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * custom.h (hpux): Added stuff to (hopefully) get `tzset'
        declared on HP/UX 10 and up.

Mon Jun  9 17:12:24 2003  Patrick T.J. McPhee   <ptjm@interlog.com>

        * awk.h (ATTRIBUTE_EXPORTED): New macro for dynamic libs on Windows32.
        * CONVMFTidx, stack_ptr, do_lint, lintfunc: Now have this attribute.

Mon Jun  9 13:11:33 2003  Arnold D. Robbins  <arnold@skeeve.com>

        Clean up of Stepan's patches.

        * array.c (get_actual): Renamed from r_get_array. Added second
        param canfatal if routine should print fatal message when not an array.
        (get_actual): Renamed 'prm' to `isparam'.
        (array_vname): Add static msglen var; only realloc string if it grows.
        Don't use `s += sprintf(...)'. No good on old systems where sprintf
        returns char *.  Minor formatting cleanups.
        (do_adump): Restored separate `a' and `r' variables; helps for debugging.

        * awk.h (SCALAR, UNINITIALIZED): Removed entirely, renumbered other flags.
        (get_array, get_param): New macros, calls get_actual.
        (get_actual): Declaration changed from that of r_get_array.

        * awkgram.y (release_all_vars): Restored previous version of code; new
        version isn't right for Node_xx variables.
        (variable): Minor code cleanup for readability.

        * builtin.c (do_match): Use get_param and print our own message when
        third parameter is not an array.

        * eval.c: Added a few comments here and there, removed some no longer
        needed comments.

        * field.c (do_split): Use get_param and print our own message when
        second parameter is not an array.

Mon Jun  9 11:46:21 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * array.c (do_delete): Initialize hash1 and last to keep gcc -Wall happy.
        * io.c (rsnullscan): Comment out label skip_leading for same reason.

Wed May 28 08:31:23 CEST 2003  Stepan Kasal  <kasal@math.cas.cz>

        * eval.c (forloops_active, in_function): Nuked.
        (pop_all_forloops, pop_fcall_stack): Are now inline.

Wed May 28 07:58:35 2003  Stepan Kasal  <kasal@math.cas.cz>

        * field.c, awk.h (Null_field): No longer static.
        * field.c (init_fields): Initial value of $0 can be Nnull_string,
          no need to copy it.
        * eval.c (r_get_lhs) <Node_field_spec>: Test for uninitialized field,
          which is Nnull_string for $0 and Null_field for $(>0).
        * builtin.c (do_print_rec): Test for uninitialized $0.

Tue May 27 17:03:02 2003  Stepan Kasal  <kasal@math.cas.cz>

        * awk.h (Node_var_new): New node type for variables which can be
        either scalar or array.  From now on, Node_var is always scalar.
        (Node_gvar_ref): Nuked, its role can be taken by Node_array_ref.
        (orig_var): Removed, orig_array is enough.
        (SCALAR, UNINITIALIZED): Flags nuked.
        (var_uninitialized): New macro to distinguish uninitialized vars;
        used in several other macros.
        * array.c (r_get_array, array_vname, do_adump): Adapt to the
        above changes.
        * awkgram.y, eval.c, field.c, main.c, node.c, profile.c: Ditto.

Tue May 27 14:27:50 2003  Stepan Kasal  <kasal@math.cas.cz>

        * array.c (r_get_array): New function, which goes all the way
        through Node_param_list to actual Node_var_array; if it encounters
        non scalar Node_var, it changes it to Node_var_array.
        (in_array, do_delete, do_delete_loop, do_adump, assoc_sort_inplace):
                Use get_array.
        (assoc_lookup): The parameter must be a Node_var_array.
        * awk.h (get_array, r_get_array): Declare the new function and define
        a macro to speed it up.
        * builtin.c (do_match): Use get_array.
        * eval.c (interpret) <Node_K_arrayfor>: Ditto.
        (r_get_lhs) <Node_K_arrayfor>: Ditto.
        * field.c (do_split): Ditto.

Tue May 27 08:23:51 2003  Stepan Kasal  <kasal@math.cas.cz>

        Changed node->vname meaning for type Node_array_ref and Node_gvar_ref.
        It contains only the reference name; one has to (recursively) follow
        node->prev_array to find out the call history for the array.

        * array.c (array_vname): New function to print the array name.
        (assoc_lookup, do_delete): Use array_vname.
        * eval.c (interpret, r_tree_eval, r_get_lhs): Use array_vname.
        (push_args, pop_fcall): Things have simplified.
        * awk.h (array_vname): Declare.
        (prev_array): Define.

Sun Jun  8 11:25:36 2003  Stepan Kasal  <kasal@ucw.cz>

        * awkgram.y (append_right): When using savetail, remember that it
        is not necessarily the tail of the list---it's just a pointer to
        the last chunk appended.

Thu Jun  5 12:01:41 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (do_strtonum): Make `strtonum(13)' work.

Wed Jun  4 17:07:06 2003  Corinna Vinschen  <vinschen@redhat.com>

        * io.c (binmode): Include function for __CYGWIN__ too.

Tue Jun  3 12:40:50 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * eval.c (interpret): Node_K_switch.  For regex case, don't
        call `free_temp' on the result of `force_string' if it's equal to
        switch_value. Thanks to John DuBois <spcecdt@armory.com>
        for finding the problem.

Sun Jun  1 13:08:22 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (format_tree): For %c, force precision to 1.

Wed May 28 11:55:48 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y (isnoeffect, isassignable): Add Node_TEXTDOMAIN to
        switches in both functions.

Wed May 28 11:38:59 2003  Stepan Kasal  <kasal@math.cas.cz>

        * awkgram.y (switch_body): Remove rule ``switch_body:/*empty/''
        as ``switch_body:case_statements'' covers it---this disambiguation
        fixes a reduce/reduce conflict.

Sun May 25 16:23:43 2003  Corinna Vinschen  <vinschen@redhat.com>

        * configure.ac: Remove linking against /usr/lib/automode.o.
        * configure: Regenerate.

Sun May 25 15:19:19 2003  Stepan Kasal  <kasal@math.cas.cz>

        * awk.h (get_lhs): For an initialized Node_var, you may return
        the address of var_value pointer, no matter whether reference
        bit was set or not.  We were silly slowing down most of the
        assignements.

        * (get_a_record): After grow_iop_buffer, move recm.rt_start even
        if recm.len == 0.

Mon May 19 16:55:59 2003  Arnold D. Robbins  <arnold@skeeve.com>

        Code for C-style switch statements. Initial version contributed by
        Michael Benzinger <Michael.Benzinger@sabre-holdings.com>.

        Disabled by default, use `configure --enable-switch' to turn it on.

        * configure.ac: New AC_ARG_ENABLE for switch statements.
        * awk.h (NODETYPE): New types for switch, case, default keywords
        and respective lists.
        * awkgram.y: New productions for switch statement. Does checking to
        avoid duplicate cases.
        * eval.c (nodetypes): New entries for new NODETYPEs.
        (interpret): New code to do switch execution.
        * profile.c (pprint): New code to print switch statements.

Mon May 19 15:05:43 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * configure.ac: Renamed from configure.in.
        * fixvers: Now looks in configure.ac.
        * Makefile.am: Now cites configure.ac.

        * Misc other: Updated to Automake 1.7.5.

Sun May 18 12:03:56 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * array.c (do_delete_loop): Fix bracing of logic for
        tests.

Wed May 14 09:01:16 2003  Stepan Kasal  <kasal@math.cas.cz>

        Misc patches:

        * builtin.c (do_match): If third parameter to `match' is supplied,
        store all subexpressions which are applicable, even though there
        are some unused between them.

        * awkgram.y (yylex): When returning from unterminated REGEXP
        (which is /* kludge */), take care to fake a yylval, to
        prevent ``internal error'' later.

Sun May 11 15:51:00 2003  Stepan Kasal  <kasal@math.cas.cz>

        * io.c (rsnullscan, get_a_record): Boundary condition bug fixes.

Sun May 11 15:15:20 2003  Scott Deifik  <scottd@amgen.com>

        * awk.h: Add decls for `memcpy_ulong', `memset_ulong', and
        MSC defines.
        * regex.c: Include <stdio.h> if MSC for size_t.

Mon May  5 15:11:06 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (get_a_record): Only tweak RT's value in place if the current
        RS scanner is the same as the last one. Bug report submitted by
        John DuBois (<spcecdt@armory.com>).

Fri May  2 14:39:48 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (get_a_record): Add logic at end to be smart about setting
        RT.  Saves considerable time, esp for default case where RS = "\n".

Wed Apr 30 11:44:38 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * field.c (do_split): Add check and code for Node_gvar_ref.
        * array.c (in_array, do_delete, asort_actual): Same.
        * builtin.c (do_split): Same for 3rd arg array parameter.
        * eval.c (interpret): Same for Node_K_array_for.
        (push_args): Same for evaluating extra args.

Tue Apr 29 15:54:28 2003  Arnold D. Robbins  <arnold@skeeve.com>

        Record reading code redone/simplified considerably.

        * awk.h (IOBUF): Removed total field, no longer used.
        * io.c (at_eof, has_data, no_data_left): New macros.
        (RECVALUE, SCANSTATE): New enumerated types.
        (rs1get_a_record, rsnull_get_a_record, rsre_get_a_record): Removed.
        (get_a_record): Rewritten, again. Now contains just buffer and
        record code; searching code moved into these functions:
        (rs1scan, rsnullscan, rsrescan): New functions to scan a buffer
        for record contents and terminator. Fill in values in:
        (struct recmatch): Holds found record and terminator.
        (spec_setup): Set iop->dataend to indicate data is already in buffer.
        (nextfile, inrec): Use new macros instead of flag and pointer tests.
        (set_RS): Set scanning function instead of record function.

        FWIW, it all passes `make test'.

Sun Apr 27 21:02:39 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (do_close): At end, if do_posix return 0. See comment in code.

Tue Apr 15 09:56:03 2003  Isamu Hasegawa  <isamu@yamato.ibm.com>

        * configure.in: Check existence of wcrtomb, and wcscoll.
        * configh.in: Likewise.
        * configure: Re-generate.
        Thanks to Kimura Koichi <kimura.koichi@canon.co.jp> for reporting.

Sun Apr 13 16:02:10 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * main.c (main): Add call to `setlocale' for LC_NUMERIC after program is
        parsed.
        (arg_assign): Switch back to "C" locale for LC_NUMERIC for command
        line assignments; this is per POSIX that period is decimal point for
        program and command line assignments and the locale's separator
        applies for input, output, and string to number conversion.

2003-03-26  Paul Eggert  <eggert@twinsun.com>

        * builtin.c [HAVE_INTTYPES_H]: Include <inttypes.h>.
        [!HAVE_INTTYPES_H && HAVE_STDINT_H]: Include <stdint.h>.
        (CHAR_BIT, INTMAX_MIN, UINTMAX_MAX): Define if the system does not.
        (TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM): New macros, taken from
        coreutils and many other GNU utilities.
        (format_tree): When formatting, use widest possible integers
        rather than settling with 'long'.
        (do_lshift, do_rshift, do_and, do_or, do_xor, do_compl): Likewise,
        when doing bitwise operations.
        * configure.in (jm_AC_TYPE_LONG_LONG, jm_AC_TYPE_UNSIGNED_LONG_LONG,
        jm_AC_TYPE_INTMAX_T, jm_AC_TYPE_UINTMAX_T): Add, since the mainline
        code now needs this.
        * doc/gawk.texi (Control Letters, Bitwise Functions): Document this.
        * m4/intmax_t.m4: New file, taken from coreutils (but renamed to
        avoid collision with our m4/inttypes.m4).
        * m4/longlong.m4: New file, taken from coreutils.
        * m4/uintmax_t.m4, m4/ulonglong.m4: Remove; superseded by the above
        new m4 files.

        * builtin.c (BITS_PER_BYTE): Remove; use CHAR_BIT instead, since
        it's the standard name.
        (do_lshift, do_rshift): Complain if the shift width is exactly equal
        to the word size, too.

Thu Mar 27 10:44:11 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (rs1_get_a_record, rsnull_get_a_record, rsre_get_a_record):
        Enhance check for no data left in file to be only if file has
        non-zero size.  Linux files such as /proc/filesystems stat as a
        regular file of size 0, but actually have contents. Ugh.
        Thanks to Martin Schlemmer <azarah@gentoo.org> for the bug report.

Wed Mar 26 12:19:32 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (format_tree): Add a lint warning at label `out_of_range'.

Tue Mar 25 12:24:38 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y (variable): For array subscript, if NAME is in the
        symbol table, but not a variable, array, or parameter, generate
        a syntax error.
        (isarray): New function, tests if a symbol can be an array.

        * custom.h: Add check for HP/UX, needed for GCC.

Mon Mar 17 09:21:09 2003  Arnold D. Robbins  <arnold@skeeve.com>

        Allow simultaneous manipulation of a global array directly
        and when passed as a parameter.

        * awk.h (Node_gvar_ref): New nodetype.
        [orig_var]: New macro.
        * array.c (do_delete_loop, do_delete): Add logic to handle
        seeing Node_gvar_ref.
        * eval.c (nodetypes): Add Node_gvar_ref.
        (r_tree_eval, r_get_lhs): Add Node_gvar_ref case.

Wed Mar 19 14:10:31 2003  Arnold D. Robbins  <arnold@skeeve.com>

        This time for sure.
                -- Bullwinkle

        * Release 3.1.2: Release tar file made.

Wed Mar 19 14:08:11 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y: Production `program --> program error'. Add a return so
        that we don't produce an infinite stream of error messages.
        Thanks to Michael Mauch <michael.mauch@gmx.de> for pointing this out.

Wed Mar 19 13:45:50 2003  Corinna Vinschen  <vinschen@redhat.com>

        * regex.c [RE_ENBABLE_I18N]: Remove definition; the one in
        regex_internal.h is better and makes things work with Cygwin.

Tue Mar 11 11:54:20 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * regex_internal.h: Don't include <limits.h> after <regex.h> was
        included in regex.c, since it could redefine RE_DUP_MAX to a lower
        value.
        (bitset_set, bitset_clear, bitset_contain): Use 1UL instead of 1 in
        left shift operations.
        * regex.c: Include <limits.h> before <regex.h>
        * regcomp.c (re_compile_fastmap_iter, init_word_char, parse_expression):
        Use 1UL instead of 1 in left shift operations.

Mon Mar 10 15:45:37 2003  Corinna Vinschen  <vinschen@redhat.com>

        Updated to automake 1.7.3.

        * config.guess, config.sub: Updated from prep.
        * Makefile.am (AUTOMAKE_OPTIONS): Add dist-bzip2 to get .bz2 files.

Tue Mar  4 10:40:46 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * version.in: Added goop for K&R compilers; forgot that I have to fix
        this file which then is used to create version.c.

Mon Mar  3 17:00:44 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * configure.in: New option --disable-lint.
        * awk.h (do_lint, do_lint_old): Conditionally declare based on NO_LINT.
        * eval.c (set_LINT): Ifdef out body if NO_LINT.
        * main.c (do_lint, do_lint_old): Conditionally compile properly.
        (main): Handle --lint argument code.

Fri Feb 28 10:43:07 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * main.c (main): Add LC_TIME to the things that get set with
        setlocale().
        * builtin.c (format_tree): Change test of `n0-- <= 0' to ==, avoids
        VMS diagnostic.

Thu Feb 27 17:48:29 2003  Pat Rankin  <rankin@pactechdata.com>

        * regexec.c (proceed_next_node): Cast re_string_get_buffer to char *.
        (get_subexp): Likewise.

Tue Feb 25 12:33:41 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * regex_internal.h, regex_internal.c, regcomp.c, regexec.c:
        Make MB_CUR_MAX into thread local variable re_mb_cur_max.

        Unrelated, from Scott Deifik:

        * io.c (grow_iop_buffer): Add checks for overflow of new buffer size.

Mon Feb 24 13:30:59 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * awk.h (gawk_mb_cur_max): Declared:
        * main.c (gawk_mb_cur_max): Defined, init to 1.
        (main): Initialize gawk_mb_cur_max.
        * awkgram.y, builtin.c, eval.c, field.c, io.c, re.c (mb_cur_max):
        Replaces all instances of MB_CUR_MAX, which is a function call (!)
        in glibc.  Big speed up, especially for -Fx case, where x is a
        single character.

        Unrelated:

        * awkgram.y (rule): For non-existent action, use a Node_K_print_rec
        node.

Sun Feb 23 15:45:20 2003  Arnold D. Robbins  <arnold@skeeve.com>

        Speed up plain `print' and `print $0':

        * awk.h (Node_K_print_rec): New node type.
        (do_print_rec): Declare function.
        * awkgram.y (simple_stmt): Create humongous test for plain `print'
        or `print $0', and if so, use a Node_K_print_rec for it.  Modify
        test for lint message.
        * builtin.c (redirect_to_fp): New function for common code to get fp
        and rp for do_print{,f,_rec} functions.
        (do_print): Use redirect_to_fp().
        (do_printf): Use redirect_to_fp().
        (do_print_rec): New function to just print $0 from field_arr[0]
        directly; will rebuild the record first if necessary.

        Unrelated:

        * regex_internal.h: Add ENABLE_NLS to the condition for using
        gettext so that --disable-nls really disables it.

Sat Feb 23 22:46:00 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (rs1_get_a_record, rsnull_get_a_record, rsre_get_a_record):
        Modify buffer-filling algorithm to always read one or more multiples
        of the blocksize (iop->readsize).
        (grow_iop_buffer): Make sure there's room for the current partially
        read record and one disk block buffer.

Thu Feb 20 22:02:00 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * re.c (research): Fix typo in cast of precision value to int.
        * regex.h, regex.c, re_internal.h, re_internal.c, regcomp.c, regexec.c:
        synced to GLIBC source, maintaining K&R portability changes, and bug
        fixes, although losing ability to compile each file separately.
        * Makefile.am (SOURCES): Moved placement of regex source files from here ...
        (EXTRA_DIST): ... to here.

Tue Feb 18 14:17:33 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * re.c (research): Cast precision value to int.
        * builtin.c (format_tree): For toofew, cast field width value to int.
        * io.c (rsre_get_a_record): Initialize restart and reend. Add a variable
        to make sure they're set before used at end of function.
        (iopflags2str): Removed decl at top and made not static so that GCC
        stops complaining that it's defined but not used. Bleah.

Mon Feb 17 11:02:34 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * config.guess, config.sub: Updated from prep.

Sun Feb 16 15:47:15 2003  Scott Deifik  <scottd@amgen.com>

        * awk.h (format_tree, make_str_node): Changed decls to match how
        they are called.
        * builtin.c (format_tree, sub_common): Same.
        * node.c (make_str_node): Same.

Wed Feb  5 14:18:01 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * awk.h: Removed duplicate decl of set_prof_file(). Removed
        undef of const for non-ANSI C; config.h should handle it.
        * msg.c (set_loc): Use srcfile and srcline in regular code to shut up
        stupid SGI compiler.

Tue Feb  4 14:28:06 2003  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y (builtin_func): New string for use in rationalizing
        function parsing and installation code.

Sun Feb  2 16:00:55 2003  Arnold D. Robbins  <arnold@skeeve.com>

        Cache function body code pointer so that only have to find it the
        first time a function is called.  This potential for optimization
        brought to my attention by Stepan Kasal.

        * awk.h [funcbody]: New macro.
        * awkgram.y (FUNC_CALL): Set $$->funcbody to NULL.
        * eval.c (func_call): Changed to take top-level Node_func_call as the
        single parameter.  Do the lookup and caching.
        (r_tree_eval): Change how func_call() is called in switch.
        * profile.c (pp_func_call): Similar changes.
        (tree_eval): Ditto.

Sun Feb  2 15:32:42 2003  Stepan Kasal  <kasal@math.cas.cz>

        ADR: More grammar rationalization/repair from Stepan.

        * awkgram.y (common_exp, simp_exp): The rule from getline (without
          pipe) has been moved from common_exp to simp_exp.

        The redirection of print statements reworked.  The idea comes from
        mawk-1.3.3; much thanks to Michael Brennan!

        * awkgram.y (IO_OUT, IO_IN): New tokens.
          (APPEND_OP, TWOWAYIO): Swallowed by the above ones.
          (in_print, in_parens): New static variables, to trace whether
          IO_OUT is expected.
          (yylex): Emit the new tokens, update in_parens on '(' and ')'.
          (exp): The print command(s) reworked.
          (oputput_redir): Reworked.
          (print_expression_list): New non-terminal.
          (rexp, rexpression_list opt_rexpression_list): Nuked.
          (exp, simp_exp): ``cmd|getline'' rule changed to
          ``cmd IO_IN getline'' and moved from exp to simp_exp.

        Unrelated:

        * awkgram.y (variable): Don't return Node_func, issue a fatal
          error instead.
        * eval.c (r_tree_eval, r_get_lhs): Omit special checks for Node_func,
          nodes of this type cannot get into the program tree.
        * profile.c (tree_eval, pp_lhs): Likewise.

Thu Jan 30 17:42:05 2003  Stepan Kasal  <kasal@math.cas.cz>

        ADR: Applied lots of patches from Stepan.

        * array.c (do_delete_loop): Call after_assign for the loop index.
        * field.c (do_split): The third argument to split(), sep, has to be
          evaluated and the result dupnoded before assoc_clear is called,
          similarily as src.  And we needn't to evaluate the third argument
          if it's CONSTant regex and the first parameter is null string.
        * awk.h (dupnode): Changed to macro, function renamed to r_dupnode.
        * node.c (dupnode, r_dupnode): Rename.
        * awkgram.y (parms_shadow): Return bool value, ...
          (shadow_funcs): ... which will enable us to end the program if
          lintfunc is fatal.
          (program): Cleanup of the rules defining the ``program'' non-terminal.
          (start, program, rule): No value associated,
          expression_value is now treated similarily as begin_block and end_block.
          (pattern, rule): Bison actions for non-terminal `pattern' now
          add a new rule to the appropriate Node_rule_list, action for
          non-terminal `rule' now only adds the associated code block

          (statements): Don't call isnoeffect($2->type) if
          $2 happens to be NULL.

        * io.c (iop_close): Based on report by Stepan Kasal and because of
        his changes, don't call reset_record() when saving a copy of contents
        of $0.
        * awkgram.y: Improved function parsing error messages for case where
        user uses a builtin name as a function name.  Based on error report
        by Stepan Kasal.
        * ext.c (make_builtin): Set FUNC flag for new function.  Based on error
        report by Stepan Kasal.

        * builtin.c (do_match): Use it in loop that fills in subpattern info.
        * eval.c (r_tree_eval): For Node_assign, don't call free_temp(),
          as assign_val() contains dupnode(), which would clear the TEMP
          flag. From Stepan Kasal <kasal@math.cas.cz>.
        * config.sub: Updated from prep.

Sun Jan 19 22:34:01 2003  Arnold D. Robbins  <arnold@skeeve.com>

Sun Nov 24 18:23:29 2002  Arnold D. Robbins  <arnold@skeeve.com>

        From Paul Eggert, with some edits by me.

        * builtin.c (do_substr): Consistently use floating point
        values for lint messages, so they should be printed pretty
        much as the user saw them.  Check for overflow before
        converting floating point to integer.  Do the right thing with
        NaNs.

        Check for index out-of-range before checking for length
        out-of-range, to avoid some nasty effects if address
        arithmetic overflows (e.g., indx + length < index).

        Allow zero-length substrings when checking for lint if
        do_lint == LINT_INVALID.

        work for GCC 3.2 and later.
        * io.c (PIPES_SIMULATED): Don't define if on AIX, which
        does define TANDEM in one of its header files. Ugh.

Tue Nov 19 15:33:55 2002  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (do_substr): Use %lu in warnings instead of %d.

Mon Nov 18 14:42:53 2002  Arnold D. Robbins  <arnold@skeeve.com>

        * config.guess: Synced from ftp.gnu.org.

Mon Oct 28 13:21:20 2002  Arnold D. Robbins   <arnold@skeeve.com>

        Applied lots of patches from Stepan Kasal, tweaked as needed
        for current code base.

        * node.c (dupnode): When n->stref overfows, flag the node as PERM.
        Same for n->ahname_ref.
        (unref): Remove the check for n->stref == LONG_MAX and
        n->ahname_ref == LONG_MAX.
        * awk.h (make_string): The third argument to make_str_node changed
        from FALSE to 0, it's not Boolean.
        (free_temp): Evaluate the argument only once, so that we
        can call free_temp(tree_eval(n)) for achieving side effects.
        (load_environ, load_procinfo): Changed return type to NODE *.
        * main.c (load_environ): The ENVIRON_node should be created with type
        Node_var_array and lnode set to NULL.  Return pointer to the created node
        and create an empty hash even on TANDEM.
        (load_procinfo): Same mods for PROCINFO_node.
        (init_args): ARGV_node should also have lnode set to NULL.
        * eval.c (r_tree_eval): case Node_assign moved just above the other
        assignment cases.
        (op_assign): ++ and -- cases merged with += and -=, respectively.
        (push_args): Evaluate all args, even in cases where more args are
        supplied then required.
        (interpret): In case Node_K_forarray, flag the variable
        num_elems also as volatile, so that it survives longjmp() and
        can be trusted when linting code.
        (r_get_lhs): Case Node_param_list was unreachable (unless
        something breaks really badly), remove it;
        (r_tree_eval): Case Node_var_array removed from the last switch,
        it was caught in the first switch above.
        * profile.c (tree_eval): Again, case Node_var_array was caught above.
        * awkgram.y (variable): Code simplified, making use of the above
        changes.
        * field.c (sc_parse_field): IGNORECASE only applies to regex based
        field-splitting, so remove code that pays attention to it.
        (do_split): Don't use parse_field if RS_is_null.
        (set_FS): Beware of FS == "\\" even if RS_is_null.

        Code changes to make things work better:
        * field.c (set_FS): Don't use cmp_nodes() to compare old and new
        value of FS, that uses IGNORECASE, which is a bad idea. Improve
        logic for choosing sc_parse_field.  Ensure that when RS_is_null
        but using a single character, that we do pay attention to
        case when doing regex splitting.
        * io.c (set_RS): Don't use cmp_nodes() to compare old and new
        value of RS, that uses IGNORECASE, which is a bad idea.

Mon Oct 28 09:43:14 2002  Arnold D. Robbins   <arnold@skeeve.com>

        * recomp.c (parse_expression): Change return statement into
        two so it'll compile for SGI cc.

        * awk.h (STR, CUR): Changed to STRCUR and NUMCUR respectively,
        to avoid conflict with STR on some System V systems.  Changed
        in all source files.

Thu Oct 24 16:14:34 2002  Arnold D. Robbins   <arnold@skeeve.com>

        * array.c (AVG_CHAIN_MAX): Now a variable, to allow easy experimentation.
        (array_init): Pulls a new value from env var AVG_CHAIN_MAX if it
        exists and sets the variable.
        * awk.h: Add declaration for array_init().
        * main.c (main): Call array_init().

Tue Oct 22 11:23:56 2002  Arnold D. Robbins   <arnold@skeeve.com>

Tue Oct 15 14:18:53 2002  Arnold D. Robbins   <arnold@skeeve.com>

        * eval.c (set_IGNORECASE): Call set_RS() instead of
        set_FS_if_not_FIELDWIDTHS().  The former calls the latter
        for us, and also makes IGNORECASE affect RS like it's supposed to.
        * field.c (FS_re_yes_case, FS_re_no_case): New variables.
        (set_FS): Smarten up routine to not recompile FS_regexp if all
        that's changed is IGNORECASE or if switching back to FS from
        FIELDWIDTHS.  Significant speed-up for cases where IGNORECASE
        is assigned to for every record.
        * io.c (RS_re_yes_case, RS_re_no_case): New variables.
        (set_RS): Similar changes as to set_FS().  In particular,
        IGNORECASE changing now affects record splitting too.
        * re.c (refree): Set rp->pat.tranaslate to NULL. It comes
        from casetable and shouldn't be freed. (Strictly necessary
        only for old regex, but a good idea anyway).
        Also, call regfree(& rp->pat) instead of manually free()ing
        things, since there's dynamically allocated stuff hiding in
        the buffer. Avoids a memory leak.

Mon Oct 14 12:02:39 2002  Arnold D. Robbins  <arnold@skeeve.com>

        Major space reduction in array management.  Overhead reduced
        to two NODE's per element from three.

        (ahnext): New definition into hash union.
        (ahvalue): New definition into hash union.
        (ahname_str): New member, points into hash union.
        (ahname_len): New member, points into hash union.
        (ahname_ref): New member, points into hash union.
        * array.c: Replaces uses of ahname member with string and
        length.  Set the reference count correctly to 1 on new nodes.
        * eval.c (interpret): Case for Node_K_arrayfor.  dupnode() the
        array indices, and set loop variable to new value made via
        make_string().
        * node.c (unref, dupnode): Node_ahash nodes are now also
        reference counted, a la strings.  Similar code is used to
        increment/decrement the counts, and/or copy nodes as
        needed.

        Unrelated:
        * awk.h (forsub): Removed. Not used.

Sun Oct 13 16:58:27 2002  Stepan Kasal  <kasal@math.cas.cz>

        * profile.c (pprint): #undef the temporary defines at the end
        of the case.
        * eval.c (interpret): Likewise.
        (assign_val): We can unref() before doing dupnode().
        Also, move the check for NF < 0 from here ...
        * field.c (set_NF): ... to here.
        * main.c (varinit): No need to call set_NF().
        * awkgram.y (statements): Don't be so generous when concatenating
        `statements' with a `statement'.

        with a comment that it's internally the same as `delete array'.
        * eval.c (Node_K_delete_loop): Increment the exec_count. Ooops.

        Saves 16 bytes per NODE.
        * eval.c: Changed use of `vname' to `varname' to avoid new
        macro.
        * main.c (lintfunc): Made ifdefed decls match awk.h.
        * eval.c (comp_func): Use memcmp instead of strcmp.
        * configure.in (AC_CONFIG_HEADER): Physically append custom.h
        to config.h to avoid subdir compiliation problems.

        (output_redir): Can contain only common_exp, not exp in general.

        (mblen_buf): New variable contains the amount of remain byte
        of corresponding multibyte character in the input string.

Fri Apr 20 06:28:59 2001  Isamu Hasegawa  <isamu@yamato.ibm.com>

        Handle a multibyte character followed by '*', '+', and '{n,m}'
        correctly.

        * dfa.c (update_mb_len_index): New function.
        Support for multibyte string.
        (FETCH): Call update_mb_len_index.

        * awk.h (MBS_SUPPORT): New flag, means supporting multibyte strings.
        * configure.in : Add check for wchar.h, wctype.h, mbrtowc, and mbrlen.

Wed Jan 16 16:32:40 2002  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (do_strtonum): Simplified.  Check first if the
          value matches a non-decimal number, and if so convert it.
          Otherwise do a regular force_number.

Mon Jan  7 22:12:15 2002  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y (statement): Moved delete, print, and expressions into
          new non-terminal `simple_stmt'.  Allow opt_simple_stmt in the
          first and third part of a for loop, per latest POSIX, which documents
          an otherwise undocumented historical oddity in Unix awk.  This has
          the pleasant side effect of making line numbers more accurate for
          messages involving delete statements.
          (opt_simple_stmt, simple_stmt): New non-terminals.

          Based on bug report from drj@pobox.com.

        * acconfig.h (TIME_T_IN_SYS_TYPES_H): Added.

Wed Dec 19 16:01:58 2001  Peter J. Farley III  <pjfarley@dorsai.org>

        * configure.in: Add MS-DOS to getpgrp special case.
        * dfa.c, getopt.c, regex.c: Fix code to work with --disable-nls.

Wed Dec 19 15:59:25 2001  Eli Zaretskii  <eliz@is.elta.co.il>

        * profile.c (init_profiling_signals) [__DJGPP__]: Use SIGINT
        instead of SIGHUP and SIGQUIT instead of SIGUSR1.

Tue Dec 18 20:56:07 2001  Andreas Buening    <andreas.buening@nexgo.de>

        More OS/2 stuff.

        * awk.h (O_BINARY): Don't redefine for EMX.
        * io.c (gawk_popen): Add __EMX__ in case compiling DOS executable.
        * configure.in: Add OS/2 to case for manual GETPGRP_VOID.

Tue Dec  4 17:54:30 2001  Arnold D. Robbins  <arnold@skeeve.com>

        New configure time option, --with-whiny-user-strftime.

        * configure.in (AC_ARG_WITH): Add appropriate code for autoconf.
        * accondig.h (USE_INCLUDED_STRFTIME): Add #undef for it.

        Mongo patch for updated OS/2 support.

        * awk.h (TOUPPER, TOLOWER): Define only if not already defined.
        * awkgram.y (extproc feature): Add ifdef for __EMX__.
        * gawkmisc.c (__EMX__): Include pc/gawkmisc.c directly.
        * io.c (__EMX__): Added for a number of places in addition to OS2 def.
          (two_way_open): Added OS/2 specific code added that uses spawn.
          (gawk_popen): Ditto.

Mon Dec  3 14:07:56 2001  Arnold D. Robbins  <arnold@skeeve.com>

        Fix use of getgroups to use dynamic memory, solves
        problem of systems where NGROUPS_MAX lies.

        * awk.h (groupset, ngroups): New extern variables.
        * configure.in (AC_CHECK_FUNCS): Add getgroups to list.
        * io.c (user_open): Use global ngroups and groupset variables,
          don't call getgroups here.
        * main.c (init_groupset): New function to init global
          vars using malloc.  Declare it at top.
          (main): Call init_groupset().
          (load_procinfo): Use global ngroups and groupset variables.

Sun Nov 18 11:56:01 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * random.c (srandomdev): ifdef-out.  Lots of compile time
          problems on multiple platforms, and gawk doesn't even
          use the routine.  The heck with fine-grained solutions.

Wed Nov 14 16:12:40 2001  Pat Rankin  <rankin@eql.caltech.edu>

        * builtin.c (bchunk_one): Use `ofre < 1' instead of `ofre <= 0'
          to avoid compiler complaint about suspicious comparison for
          unsigned variable.  (`ofre == 0' ought to suffice...)

Tue Nov 13 17:27:52 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y (yyerror): Fix the code to behave like it
          used to.  Keep "no arbitrary limits" by mallocing the
          buffer and freeing it.

Wed Nov  7 16:46:20 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y (yyerror): Remove dependency upon buf[] to
          hold prepended space and `^' pointer.  Avoids core dumps
          for long source lines.

Sat Nov  3 22:27:21 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * m4/strtod.m4: Add missing `#endif'. Oops.

Mon Oct 29 14:53:57 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y: Add semicolons in calls to count_args().
          Apparently bisoon adds a semicolon to each body
          automatically and byacc doesn't.

Sun Oct 28 16:53:18 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (format_tree): Fix off-by-one error in "ran out
          for this one" diagnostic.  Also fix lint check for too many
          arguments vs. count in format string.

Wed Oct 10 11:01:47 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * fixvers: Check that files exist before doing `cmp', in
          case they're in a source code system and aren't there.
          Fix from Grant Erickson (gerickson@brocade.com).

Thu Oct  4 18:20:36 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * eval.c (r_tree_eval): For comparison, dupnode() results of
          evaluation so that we can hang on to them and avoid memory
          corruption.  Change calls to free_temp() to unref().

Tue Sep 25 15:19:53 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (iop_open): Only call os_close_on_exec() for
          fd > fileno(stderr).

2001-09-07  Paul Eggert  <eggert@twinsun.com>

        * io.c (redirect): When deciding to use the fdopen bug hack,
          use "__sun" rather than "solaris".  No compilers predefine
          "solaris", but both GCC and Sun C predefine "__sun".

Thu Aug 30 15:17:12 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * main.c (copyleft): Use a printf %d for last year of update
          to avoid translation strings changing when the file
          is updated from now on.  Suggestion from Ulrich Drepper.

Thu Aug 23 14:01:14 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y (unary minus production): Add check that value
          isn't a string. Based on bug report from drj@pobox.com.
        * profile.c (tree_eval): For node_val, only test NUMBER
          to see if value is numeric, not NUM|NUMBER.

Thu Aug 16 12:21:28 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * configure.in (ALL_LINGUAS): Added `fr' and `tr'.
        * po/fr.po, po/tr.fo: New files.

2001-08-13  Paul Eggert  <eggert@twinsun.com>

        This patch fixes a bug that causes gawk to rewind standard
        input incorrectly.  It also removes all instances of fseek,
        from the gawk source proper, which should make gawk a bit
        more portable.

        (The original patch removed off_t & lseek too, but I need
        that for something else. ADR.)

        * posix/gawkmisc.c (optimal_bufsize):
        Don't use lseek on the input, because that might change
        its state.  Instead, just check whether it is a regular file.
        This obviates the need to invoke isatty.
        (Also, fix a spelling error in the first line of the source.)
        * pc/gawkmisc.pc, unsupported/atari/gawkmisc.atr: Likewise.

        * awk.h (S_ISREG): Move this macro here ...
        * io.c (S_ISREG): from here.

        * protos.h (fseek): Remove prototype; no longer used.

Fri Aug  3 13:38:54 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * array.c (assoc_lookup): Change assert test on type to real test
          to protect against FS[1] = "x" kinds of things.  It'd be better
          to do this in the grammar, but this is easier and just as
          effective.

        Undid BECAMEARRAY changes of 25 June 2001 in favor of correct code:
        * eval.c (pop_fcall): Change test and comment for freeing n->vname.
          (flags2str): Removed BECAMEARRAY entry.
        * awk.h (BECAMEARRAY): Removed define.
        * array.c (assoc_lookup): Removed setting of BECAMEARRAY flag.

Mon Jul 23 17:33:13 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (get_a_record): Handle case where RS = "" and input file
          is only newlines.  See test/onlynl.   Bug report by
          Michel Jouvin <jouvin@lal.in2p3.fr>.

Wed Jul  4 18:34:19 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * eval.c (assign_val): Don't allow negative values for NF.
        * field.c (set_NF): Robustify field-freeing code to make sure
          values are always positive.

Sun Jul  1 19:15:01 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (do_index): If second string is "", return 1.

Mon Jun 25 19:34:24 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y (mk_rexp): Use Node_dynregex.
        * eval.c (nodetypes): Add Node_dynregex.
          (r_tree_eval): Add Node_dynregex to case for match_op().
        * profile.c (tree_eval): Add Node_dynregex to case for pp_match_op().
          (pp_match_op): Handle Node_dynregex, simplify cases for ~ and !~.
        * re.c (re_update): Add assertion that type is Node_regex when flags
          indicate CONST.

        New lint warning.

        * awkgram.y (yylex): Added lint warning that constant with leading
          zero is treated as octal or hex.

        Generalized code for those who are Strong In The Ways of the Source.

        * awk.h: New boolean variable.
        * main.c (main): Set it.
        * eval.c (interpret): For arrays, check it. Remove variable 'first',
          not needed anymore.
        * profile.c (pp_string_fp): Enable printing of non-ASCII characters
          verbatim if variable set.

        Fix memory corruption on SCO for array vars as params changed globally.

        * awk.h (BECAMEARRAY): New flag.
        * array.c (assoc_lookup): Set the flag as appropriate.
        * eval.c (flags2str): Add the flag.
          (pop_fcall): Check the flag, don't free memory if set.

Wed Jun 13 18:07:06 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * eval.c (fmt_index): Actually call erealloc() to grow fmt_list
          if that's really necessary.  Bug report from David Jones,
          djones@zoonami.com.

Sun Jun 10 14:24:48 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * profile.c (pp_match_op): Rationalized the code.

Thu Jun  7 11:54:36 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * awk.h (O_BINARY): Don't define if already defined
          (as is true for cygwin/gcc --- oops).

Sun Jun  3 13:04:44 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * Release 3.1.0: Release tar file made.  And there was
          rejoicing.

Wed Apr 25 11:44:07 2001  Arnold Robbins  <arnold@skeeve.com>

        * Makefile.am (AM_MAKEFLAGS): Add definition per advice from
          Nelson Beebe.

        * io.c (devopen): Patch from Jeurgen to robustify pulling
          out hostname, port numbers, etc, to avoid any buffer overrun
          problems.

Mon Apr 23 10:26:38 2001  Arnold Robbins  <arnold@skeeve.com>

        * awkgram.y: Fix grammar so that `print ... |& ".." |& getline'
          dies with a parse-time error message.

Sun Apr 22 16:46:48 2001  Arnold Robbins  <arnold@skeeve.com>

        * io.c (socketopen): Fix from Juergen in recursive call.

        * random.c: Remove decl of random().

Mon Apr  9 11:41:58 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * dfa.c (dfainit): Initialize more members in the structure,
          based on bug report in bug.gnu.utils by aaronl@vitelus.com
          (Aaron Lehmann).
        * awk.h: Fix logic around include of <sys/types.h>.

Thu Apr  5 20:12:05 2001  Pat Rankin  <rankin@eql.caltech.edu>

        * dfa.c: For VMS, #include <stddef.h> instead of <sys/types.h>.
        * missing_d/mktime.c: Likewise.

        * random.c: Reorder include directives to get gawk config info
          from random.h sooner.
          [fcntl.h]: Guard #include with HAVE_FCNTL_H test.
          [unistd.h]: Guard #include with HAVE_UNISTD_H test.

        * random.c (srandomdev): Skip /dev/urandom usage if O_RDONLY

          if the pipe died with a signal.

Wed Mar  7 11:28:52 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (get_a_record): Correctly handle the case of a leading
          single newline at the front of the file when RS = "".

2001-02-26  Paul Eggert  <eggert@twinsun.com>

        * COPYING: Incorporate latest version from FSF, which fixes a Y2k bug.

        * builtin.c (do_mktime): Allow the user to specify the
          tm_isdst member as an optional trailing integer, and to
          specify "out-of-range" members.  Check for overflow when
          subtracting 1 from month or 1900 from year.  Allow years just
          past INT_MAX, as they work on some hosts when INT_MAX - 1900
          is representable as an int.

        * doc/gawk.1, doc/gawk.texi: Document the above changes.
          Also, document that the origin-zero Gregorian calendar is used.
          Fix confusing wording about "midnight" by replacing it with 00:00
          ("midnight" is also 24:00, the end of the day).
          Mention the typical range for time stamps.
          Do not assume that years are nonnegative and are less than 10,000.
          Suggest TZ=UTC0 instead of TZ=GMT0, as that's how recent versions
          of GNU date behave.
          GMT is not always the time of day in Greenwich these days.
          Fix typos: "Emporer/Era", "1980's", "1970's".

        * m4/largefile.m4: Synchronized with latest version.

Tue Feb 27 12:10:11 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * profile.c (pp_in_array): Change test to tree->type == Node_expression_list.

Wed Feb  7 14:46:50 2001  Arnold D. Robbins  <arnold@skeeve.com>

        * awkgram.y (LEX_FOR): Allow newline after `;' in for loops.
          Per bug report from Brian Kernighan, bwk@research.bell-labs.com.

Tue Feb  6 18:35:27 2001  Martin C. Brown    <mc@whoever.com>

        * io.c (socket_open): Conditionalize various options based on
          ifdef. Needed for BeOS port.

Tue Feb  6 18:17:13 2001  Michal Jaegermann  <michal@ellpspace.math.ualberta.ca>

        * regex.c (re_match_2_internal): Case maybe_pop_jump, for
          charset and not_charset: Change cast from (unsigned char)
          to (unsigned).  Catches last 8 chars with high bit set
          if backtracking. See test/rebt8b1.awk, test/rebt8b2.awk.

        Have `for (iggy in foo)' save the elements and loop over them.
        Make sorted for loops a dynamic test instead of a compile time test.

        * Makefile.am, */Makefile.am: Moved directories that don't need
          the automake machinery into EXTRA_DIST as appropriate and
          removed the Makefile{,.am,.in} files as needed.
        * eval_p.c, profile_p.c: New files to make it easier with automake
          to compile pgawk.

        * array.c (assoc_lookup): Reverted change that did dupnode of
          array indices.  Creates significant problems if index is
          numeric value and CONVFMT changes.  Added fix to set
          bucket->ahname->stfmt to -1 so that force_string never recalculates
          the string value, and also turned off NUM and turned on STR.
          See test/arynasty.awk.

Mon Oct 16 12:21:26 2000  Arnold D. Robbins  <arnold@skeeve.com>

          rp from list if either closing both ends or both ends
          have been closed separately. Add exitwarn message for
          co-process.
          (flush_io): Add warning message if fflush of co-process
          fails.  Rationalize return value to either 0 or -1.
        * builtin.c (do_gensub): 3rd arg of zero generates a
          warning.
          (do_fflush): Rationalize return value: -1 for unopen or read-only

        * io.c (do_close): Make close(x) for non-open x return -1
          and update ERRNO.  close(FILENAME) no longer does anything
          magic; this is all for better consistency with other awks
          and is more logical, anyway.

Thu Sep 28 17:27:16 2000  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (close_one): Added a lint warning if it becomes

          (gawk_pclose): Check that rp->iop != NULL before closing,
          all three versions.

          chars or after embedded newline, for --gen-po.
          Fix the calls to it everywhere for new boolean option
          to yes/no break lines.
        * m4/strtod.m4: New file, defines GAWK_AC_FUNC_STRTOD_C89.
        * configure.in: GAWK_AC_FUNC_STRTOD_C89 call added
        * acinclude.m4: Include strtod.m4.
        * acconfig.h: Add entry for STRTOD_NOT_C89.
          Remove entries for BITOPS and NON_DEC_DATA.

          if set.
        * missing/strtod.c: Make smarter for input like 0x345.
        * awk.h: [STRTOD_NOT_C89]: Define strtod gawk_strtod to get
          our version.  Avoids linker weirdness.

Mon Sep  4 09:16:43 2000  Arnold D. Robbins  <arnold@skeeve.com>

        * field.c (set_record): Fix from Utz-Uwe Haus
          <haus@saturn.Math.Uni-Magdeburg.DE> to make sure there's
          always enough room in the record.
        * builtin.c (nondec2awknum): Fix octal conversions to exit
          when hitting a non-digit, and not go to decimal.  Make
          check for non-octal better.  Based on bug report from
          Morris_Lee@tvratings.com.

Sun Sep  3 13:52:11 2000  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (format_tree): Allow positional parameters for
          %*.* kinds of things.

        Made octal/hex constants and strtonum on by default. Made
        --enable-non-decimal-data a runtime switch `--non-decimal-data'.

        * configure.in: Removed AC_ARG_ENABLE for --enable-bitops and
          --enable-non-decimal-data.
          In .developing check, remove the AC_DEFINEs.
        * awk.h: Decls for bitwise functions now there by default.
          Add decl of `do_non_decimal_data'.
        * main.c (do_non_decimal_data): New variable
          (optlist): Add new entry for `--non-decimal-data'.
          (main): Turn off `do_non_decimal_data' if `do_traditional'.
          (usage): Add the new option.
        * node.c (r_force_number): Make check for non-decimal data a
          runtime check based on do_non_decimal_data.

          nondec2awknum.

Tue Aug 29 18:45:56 2000  Arnold D. Robbins  <arnold@skeeve.com>

        * configure.in: Go back to ARRAYDEBUG if .developing set.
        * awkgram.y: Use ARRAYDEBUG for adump(), use multiple tests
          for stopme().

Mon Aug 28 17:09:06 2000  Arnold D. Robbins  <arnold@skeeve.com>

        * field.c (do_split): Add check for first arg is null string,
          if so, skip the work and return zero.

Mon Aug 14 23:01:55 2000  Arnold D. Robbins  <arnold@skeeve.com>

        Add %COUNT$... handling to printf.

        * awk.h (printf_count): New define in NODE structure.
          (format_tree): Added decl.

                a node.
          [print productions]: Call the function.
        * (snode): For do_sprintf, call count_args, set the count
                in the lnode.

Sun Aug 13 11:10:41 2000  Arnold D. Robbins  <arnold@skeeve.com>

        Changes from Alan J. Broder (ajb@woti.com):
        - Array third arg to match puts subtexts into the array:

        * awk.y (tokentab): "match" gets third arg, and lint warning
        * builtin.c (do_match): If third arg there, fill it with subtexts

        - New builtin sort function:

        * awk.h (do_sort): Declared.
        * array.c (do_sort, dup_table, merge, merge_sort, assoc_from_list,
          assoc_sort_inplace): New functions.

        * eval.c (tree_eval): In debug code, make uninitialized var
          a warning, not a fatal error.  Breaks too many things.

Wed Aug  9 10:51:41 2000  Arnold D. Robbins  <arnold@skeeve.com>

        * eval.c (func_call): Increment the exec_count on the
          function's node; this allows printing a call count for
          functions.
          profile.c (pp_func): Print the count for functions.
        * ALL: Changed DEBUG to GAWKDEBUG in all gawk files, so that
          I don't get regex/dfa debugging.  In some cases, changed
          memory-related stuff to MEMDEBUG.  Still have work to do.
        * awk.h, node.c, profile.c: Removed exec_count_init variable;
          code has been cleaned up to not need different values for
          profiling/not profiling.

Thu Jul  5 21:10:59 2000  Arnold D. Robbins  <arnold@skeeve.com>

        * eval.c (casetable): Removed the USE_PURE_ASCII stuff; it
          was never documented.  Latin 1 forever.
        * main.c (main): Only call `init_profiling' after arg parsing
          if `do_profiling' is still false.  Avoids resetting `prof_fp'
          back to stderr.

2000-02-17  Akim Demaille  <akim@epita.fr>

        * m4: New directory.

        not GAWK_FUNC_MKTIME.
        * acconfig.h: Removed _FILE_OFFSET_BITS, _LARGEFILE_SOURCE and
        _LARGE_FILES now templated by m4/largefile.m4.

2000-02-15  Arnold Robbins  <arnold@skeeve.com>

        * MOVED TO AUTOMAKE AND GETTEXT.
          Just about every file touched.  Work done by Arno Peters.

Sun Jan  2 14:48:23 2000  Arnold D. Robbins  <arnold@skeeve.com>

        First edit of the new millenium!

        * awk.h (NODE): exec_count now in #ifndef NO_PROFILING.
        * Makefile.in: Changes to only recompile eval.c and profile.c to a
          special version for profiling.
        * custom.h [MSC_VER]: Turn on NO_PROFILING to omit the exec_count
          and save space.
        * node.c (more_nodes): Move setting of exec_count to
          #ifndef NO_PROFILING.

Thu Jul  1 12:12:05 1999  Arnold D. Robbins  <arnold@skeeve.com>

        * configure.in (AC_PREREQ): Update to 2.13.
          GAWK_AC_C_STRINGIZE: convert to AC_C_STRINGIZE.
        * aclocal.m4 (GAWK_AC_C_STRINGIZE): Remove definition, now
          part of autoconf.
        * acconfig.h (HAVE_STRINGIZE): Ditto.

        * array.c (assoc_lookup): Fix call to fatal to lintwarn instead.
        * node.c (r_force_number): Use `0 &&' to disable warnings about
          conversions: they're overzealous, methinks.

Thu Apr  8 14:27:58 1999  Arnold D. Robbins  <arnold@skeeve.com>

          New features for profiling:

        * awk.h (NODE): Add `exec_count' member.

Wed Mar 10 21:38:14 1999  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (close_redir): Use update_ERRNO() instead of manually
          doing it.

Mon Dec 21 15:58:21 1998  Arnold D. Robbins  <arnold@skeeve.com>

        * configure.in: Add BeOS to list of cases where we hardwire
          GETPGRP_VOID.
          custom.h: Remove the #define from __be_os case. Cleaner to
          do it all in configure. Based on email from Martin C. Brown,
          mc@whoever.com.

Mon Nov 30 20:52:52 1998  Arnold D. Robbins  <arnold@skeeve.com>

        * eval.c (update_ERRNO): New function, mainly for use by
          extension functions.
        * awk.h: Add decl.

          - ability to load a dynamic library to add built-ins
          - VERSION variable (may or may not stay)
          Additional change:
          - --lint=fatal makes lint errors become fatal
          - LINT="fatal" has the same effect, any other positive
            value makes lint errors be just warnings
        * Makefile.in (includedir): New variable for gawk header files
          (ext.c, ext.o): New source and object files
          (OTHERS, extension): New directory for macro with example extension
          (install): Install header files
        * acconfig.h (DYNAMIC): New macro, true if can do dynamic loading
        * array.c (assoc_lookup): New parameter `reference' is true if we
          want to do reference  checking. Add appropriate reference checking
          code.
        * awk.h (UNITITIALIZED): New flag
          (lintfunc): Function pointer for correct function to use
          (lintwarn): New macro to produce warnings
          (result): New macro for func call result, used in commented out
          code in eval.c.
          (getnode, freenode): Revised to set UNINITIALIZED.
          (get_lhs): Third arg for reference checking, change all calls
          -- Add appropriate decls of new/changed functions
        * awk.y (tokentab): New builtin "extension" for adding extensions
          (node_common): Set flags to UNINITIALIZED for Node_var.
        * configure.in (dynamic linking): New check. Probably should
          be a separate macro.

          (main): Add case in option processing for --lint.
          (varinit): Add entries for VERSION and EXTENSION.
        * node.c (r_force_number): Checks that string really is a number.
          (morenodes): Set UNITIALIZED in the flags.
        * re.c (all): Change `result' to `res' globally to avoid conflict
          with new macro.
        * GLOBAL: Change lint calls to warning() to  lintwarn().
        * GLOBAL: Change all calls to get_lhs() to have 3rd arg.
        * GLOBAL: Change all calls to assoc_lookup() to have 3rd arg.

Sun Nov 22 17:07:39 1998  Arnold D. Robbins  <arnold@skeeve.com>

        * patchlev.h: Renamed from patchlevel.h to make life
          easier for the PC guys.

          (Makefile.in): Changed to ref patchlev.h where needed.

Sat Nov  7 21:29:52 1998  Arnold D. Robbins  <arnold@skeeve.com>

        * eval.c (r_get_lhs): case Node_field_spec.  Fix the lint
          warnings for field reference of null string or non-numeric value.
          When turned on, $0 generated a warning!  Oops.

Thu Nov  5 16:58:38 1998 Arnold D. Robbins  <arnold@skeeve.com>

        * main.c (init_fds): New function to pre-open 0, 1, and 2 on
          /dev/null if they're not open. Robustness, more or less.
          (main): Call init_fds.
        * io.c (str2mode): Add smarts for two-letter strings
          such as "rw", "r+", "wr", "w+" and "a+".

Mon Nov  2 16:55:46 1998 Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (do_*): Added lint checks for non-numeric
          and/or non-string arguments, as appropriate. This should
          have been done long ago.

Tue Oct 20 21:56:06 1998  Arnold D. Robbins  <arnold@skeeve.com>

        * awk.h (LINT_node): New variable for LINT special var

        * eval.c (nodetypes): New entry for Node_LINT.
          (r_get_lhs): Case added for Node_LINT.
          (set_LINT): Set do_lint from LINT variable.

Mon Oct 19 22:35:46 1998  Arnold D. Robbins  <arnold@skeeve.com>

        * configure.in: For GCC, add -Wall to get warnings for development.
        * Makefile.in (awktab.c): Move sed stuff to separate script.
        * bisonfix.sed: New script, with old fix and Solaris x86 fix.
        * awk.h (nodetype2str): Add declaration.
          (load_procinfo): Add declaration.

Tue Oct 13 22:28:56 1998  Arnold D. Robbins  <arnold@skeeve.com>

          Changes to make PROCINFO["FS"] reflect the use of FIELDWIDTHS or FS.

        * eval.c (assign_val): New function that does the mechanics of
                 assignment
        * main.c (load_procinfo): Add setting of PROCINFO["FS"] to "FS".
        * field.c (update_PROCINFO): New function to update the array.
          (set_FS): Call update_PROCINFO.
          (set_FIELDWIDTHS): Ditto.

Sun Sep 27 10:18:05 1998  Arnold D. Robbins  <arnold@skeeve.com>

        * awk.h (reisstring): New prototype.
        * re.c (reisstring): New function, returns true if the re did
          a simple string match. This is rather simplistic in its logic.
        * io.c (get_a_record): In the case that RS is a regexp, AND
          the re matched at the exact end of the buffer, add a call to
          `reisstring' in case it's a simple string match. If so, we
          don't need to read more into the buffer because we don't
          have a regex like `x.*y' that might extend longer.
          This should be very helpful for interactive /inet clients
          where something like `RS = "\r\n"' happens.

Thu Aug 13 22:07:40 1998  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (socketopen): Fixes from Juergen Kahrs to socket
          opening code for "any host".

Tue Jul 14 19:02:33 1998  Arnold D. Robbins  <arnold@skeeve.com>

        * aclocal.m4 (GAWK_AC_LIB_SOCKETS): Removed the caching;
          configure gave different results the second time it was run!

Fri Jul 10 09:11:06 1998  Arnold D. Robbins  <arnold@skeeve.com>

        * eval.c (interpret): Minor cleanups: add variable name to
          fatal error Node_K_array_for and other minor changes.

Mon Jun 22 16:53:34 1998  Arnold D. Robbins  <arnold@skeeve.com>

        * Makefile.in (tags, TAGS): Add $(LIBSRC).

Tue Jun  2 15:23:05 1998  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (devopen): Relax previous change, don't require "any",
          just that a port be there. The user can put 0 if they
          don't care.

Wed May 27 21:33:45 1998  Arnold D. Robbins  <arnold@skeeve.com>

        * io.c (devopen): For /inet, require that local and remote
          ports and the remote hostname be there, and that `any'
          be used for a port if they don't care.

Thu May 21 14:13:46 1998  Arnold D. Robbins  <arnold@skeeve.com>

        * node.c (parse_escape): Add warning that is always on
          for \q for any unknown q inside string or regex constant.
          I got bit by this myself once too often. Or else I'm
          just getting old and senile.

Mon May  4 12:42:49 1998  Arnold D. Robbins  <arnold@skeeve.com>

        * awk.h (NODETYPE): Sorted the Node_xxx entries for the
          builtin variables. Gotta look nice, don't we?
        * eval.c (nodetypes): Ditto.
          (genflags2str): Added code to check that we don't
          overflow the static buffer. This is just a debugging
          routine, not worth the hassle of dynamic allocation.

Mon Mar  2 16:06:16 1998  Arnold D. Robbins  <arnold@skeeve.com>

        * Makefile.in (dist): Remove any embedded copied RCS or CVS
          directories.

Mon Feb 23 00:09:52 1998  Arnold D. Robbins  <arnold@skeeve.com>

        * awk.h (genflags2str): Add declaration.
        * eval.c (genflags2str): New function.
          (flags2str): Use new general purpose function.
        * io.c (redflags2str): Same.

Sun Feb 22 23:57:29 1998  Arnold D. Robbins  <arnold@skeeve.com>

        Significant changes to add two-way i/o and sockets!!!

        * Makefile.in: Add @SOCKET_LIBS@ to LIBS variable.
        * acconfig.h: Add HAVE_SOCKETS and HAVE_PORTALS defs.
        * aclocal.m4: New macro GAWK_AC_LIB_SOCKETS.
        * awk.h: New node type, Node_redirect_twoway, and new redirection
          flags: RED_TWOWAY, and RED_SOCKET.
        * awk.y (parser): Add TWOWAYIO token and appropriate productions.

        work around glibc 2.1.3 bug.

        * awk.y (yylex): Made ']' not one of the characters
          that sets `want_assign' to false.  `a[i] /= 2' was
          broken.  Per bug report from Kristofer T. Karas
          <ktk@ktk.bidmc.harvard.edu>.

Wed Dec 22 15:06:37 1999  Arnold D. Robbins  <arnold@skeeve.com>

        * awk.y: Removed declarations of functions before
          definition of `tokentab[]'.  They're redundant with
          what's in awk.h.

Thu Dec  9 17:01:07 1999  Arnold D. Robbins  <arnold@skeeve.com>

        * node.c (parse_escape): Add lint warning for unrecognized
          escape sequences.

Mon Dec  6 15:17:34 1999  Arnold D. Robbins  <arnold@skeeve.com>

        * main.c (usage): Changed bug reporting email addresses to
          be a reference to `Bugs' node in the online and printed
          doc, instead.

Thu Dec  2 13:08:18 1999  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (do_compl): Test `d' for negative inside the do_lint
          test, not uval.  Ooops.

Fri Nov 26 10:58:36 1999  Arnold D. Robbins  <arnold@skeeve.com>

        * array.c (assoc_find):  ALWAYS compare indexes as strings,
          don't use cmp_nodes in case they are numeric.  Oh my.
          Talk about a Day 1 bug!

Tue Nov 23 11:58:53 1999  Arnold D. Robbins  <arnold@skeeve.com>

        * regex.c (SYNTAX): Cast argument to `unsigned char' instead of
          &-ing with 0xFF.  Hopefully somewhat more portable, ala 21 Nov 99
          changes to awk.y.

Sun Nov 21 22:25:27 1999  Paul Eggert  <eggert@twinsun.com>

        * aclocal.m4 (AC_SYS_LARGEFILE_FLAGS): Work around a
          problem with the QNX 4.25 shell, which doesn't propagate exit
          status of failed commands inside shell assignments.

Sun Nov 21 20:33:35 1999 Arnold D. Robbins  <arnold@skeeve.com>

        * awk.h (nextc): Remove declaration, don't need it here.
          awk.y (nextc): Cast values to unsigned char so that latin-1
          characters in strings don't turn themselves into EOF.
          Most notably y-umlaut, which is decimal 255.

Mon Nov  1 20:00:25 1999  Arnold D. Robbins  <arnold@skeeve.com>

        * regex.c (init_syntax_once): Move below definition of
          ISALNUM etc., then use ISALNUM to init the table, so that
          the word ops will work if i18n'ed.
          (SYNTAX): And subscript with 0xFF for Latin-1 characters.

Mon Oct 25 18:37:13 1999  Arnold D. Robbins  <arnold@skeeve.com>

        * awk.h, main.c, io.c: Undo previous changes (22 Oct 1999).
        * main.c (main): Move call to `init_fields()' to before
          arg parsing.  This allows `-v NF=blah' to work ok.

Fri Oct 22 17:43:40 1999  Arnold D. Robbins  <arnold@skeeve.com>

        * main.c (arg_assign): Add new arg, `initing' for icky special
          casing of -v of special variables.  Use it to check for NF.
          May need to add other cases later.
          (pre_assign): Change call arg_assign, passing initing=TRUE;
          io.c (nextfile): Change call arg_assign, passing initing=FALSE;
          awk.h: Change prototype for arg_assign.

Tue Oct 19 16:06:48 1999  Paul Eggert  <eggert@twinsun.com>

        * io.c (close_redir): Don't munge errno between setting it and
          using it.

Wed Oct  6 17:47:47 1999  Arnold D. Robbins  <arnold@skeeve.com>

        * main.c (arg_assign): Return NULL on bad variable.  Allows
          things like `./3x=stuff' to work as a filename.

Thu Sep 23 21:35:46 1999  Paul Eggert  <eggert@twinsun.com>

        * aclocal.m4 (GAWK_AC_SYS_LARGEFILE_FLAGS): Work around GCC
          2.95.1 bug in HP-UX 10.20 or later. (Had to fix the fix. ADR. :-)

Tue Sep 21 13:31:36 1999  Arnold D. Robbins  <arnold@skeeve.com>

        * builtin.c (format_tree): For '0', only set zero_flag if we
          haven't seen the field width or precision yet.

Mon Aug  9 13:06:01 1999  Arnold D. Robbins  <arnold@skeeve.com>

        * array.c (assoc_lookup): Removed code that gave each array
          a private copy of each index.  Balloons memory usage for
          no good reason that I can see.  Just use dupnode in all
          cases.
        * configure.in: Check for $srcdir/.developing adds extra
          defines for my testing/debugging use.  Yes, hack alert.

Sun Aug  1 11:02:02 1999  Arnold D. Robbins  <arnold@skeeve.com>

        * node.c (dupnode): Turn off FIELD when copying nodes.
        * array.c (do_adump, assoc_dump): New functions for array debugging.
        * awk.y (tokentab): Conditionally add "adump" function for debugging.
        * awk.h: Delcare new functions.

Thu Jul 29 23:26:40 1999  Arnold D. Robbins  <arnold@skeeve.com>

        From wsanchez@apple.com:
        * Makefile.in (install-strip): New target, coding stds. compatibility.
        * config.guess, config.sub: Add MacOS X recognition.

Thu Jul 29 19:09:19 1999  Arnold D. Robbins  <arnold@skeeve.com>

        * awk.y (func_install): Make `function foo(foo)' a fatal error.
          eval.c (r_tree_eval): Diagnose use of a function name as a
          variable inside the function.

Sun Jul  4 16:53:14 1999  Arnold D. Robbins  <arnold@skeeve.com>

        * eval.c (eval_condition): Add extra braces to avoid
          gcc warning.  I'm not going to bother for the library
          code like dfa and regex.

Wed Jun 30 16:14:36 1999  Arnold D. Robbins  <arnold@gnu.org>

        * Release 3.0.4: Release tar file made.  This time for sure.

Wed Jun 30 16:10:11 1999  Arnold D. Robbins  <arnold@gnu.org>

        * awk.h: Add include of <assert.h>, and comment about config.h
          having to be included before any system headers.  Otherwise,
          with egcs-2.91.66 and later on Linux systems, and possibly
          others, things break badly, due to the LFS macros.
        * awk.y, builtin.c, eval.c, field.c, io.c: Removed include
          of assert.h

Wed Jun  9 11:39:19 1999  Paul Eggert  <eggert@twinsun.com>

        Port the large-file code to AIX, HP-UX, and IRIX.
        Add cross-compilation support for large files.

        * config.guess, config.sub: New files.

        * configure.in (AC_CANONICAL_HOST):
          Add; GAWK_AC_SYS_LARGEFILE needs this.
          (GAWK_AC_SYS_LARGEFILE): Renamed from GAWK_AC_LARGE_FILES.

        * aclocal.m4 (GAWK_AC_SYS_LARGEFILE): Renamed from GAWK_AC_LARGE_FILES.
          Add support for AIX and HP-UX.
          (GAWK_AC_SYS_LARGEFILE_FLAGS, GAWK_AC_SYS_LARGEFILE_SPACE_APPEND,
          GAWK_AC_SYS_LARGEFILE_MACRO_VALUE): New macros.

        * acconfig.h (_FILE_OFFSET_BITS, _LARGEFILE_SOURCE, _LARGE_FILES):
          New macros.

        * Makefile.in (MISC): Add config.guess and config.sub so they get
          included in the distribution.

Wed Jun  9 11:29:29 1999  Paul Eggert  <eggert@twinsun.com>

        * io.c (iop_alloc): Don't mmap files whose sizes don't fit in `int'.
          [ This isn't really needed, as HAVE_MMAP is #undef'ed at the top,
          but it's there in case people want to take their life in their hands. ]

Sun Jun  6 11:28:07 1999  Arnold D. Robbins  <arnold@gnu.org>

        * BETA Release 3.0.46: Release tar file made.

Wed Jun  2 14:36:24 1999  Arnold D. Robbins  <arnold@gnu.org>

        * PORTS: Updated with a more recent list of systems
          that gawk compiles and tests ok on.

Tue Jun  1 14:24:59 1999  Arnold D. Robbins  <arnold@gnu.org>

        * BETA Release 3.0.45: Release tar file made.

Tue May 25 16:32:37 1999  Arnold D. Robbins  <arnold@gnu.org>

        * builtin.c (format_tree): More smarts for weird cases, such as
          zero precisions and zero values used with the `#' flag.
          Thanks to Andreas Schwab (schwab@gnu.org) for pointing these out.

Wed May 19 14:02:54 1999  Arnold D. Robbins  <arnold@gnu.org>

        * io.c (do_close): Move test for `close(FILENAME)' to after
          loop through all open redirections. Fixes problems in obscure
          cases with redirections in END rules.

Sun May 16 14:08:39 1999  Arnold D. Robbins  <arnold@gnu.org>

        * awk.y (yylex): Fix group of characters including ',' to
          set want_assign = FALSE.  Fixes bizarre parsing problems in
          function call lists, for example.
        * io.c (get_a_record): Repair logic for single-leading-newline
          case.

Tue May 11 16:48:11 1999  Arnold D. Robbins  <arnold@gnu.org>

        * aclocal.m4 (GAWK_AC_AIX_TWEAK): New macro.
        * configure.in: Call it
        * Makefile.in: (awklib/all): Pass CFLAGS on to sub-make so
          that password programs will get AIX magic defines. Avoids
          having to tweak program code for those in doc/gawk.texi.

Mon May  3 16:56:23 1999  Arnold D. Robbins  <arnold@gnu.org>

        * array.c (do_delete): Don't free_temp(subs) until after all
          references to it are finished.

Mon May  3 13:41:16 1999  Arnold D. Robbins  <arnold@gnu.org>

        * BETA Release 3.0.44: Release tar file made.

Sun May  2 18:25:43 1999  Arnold D. Robbins  <arnold@gnu.org>

        * io.c (get_a_record): Do a really good job of stripping newlines
          from the front of records when RS = "" and there's only one
          newline at the front of the file, which the regex didn't catch.

Wed Apr 28 12:27:49 1999  Arnold D. Robbins  <arnold@gnu.org>

        * configure.in: More HP stuff: fix the manual alloca code so that
          gawk will compile and link on HP systems. See the comments.

Sun Apr 25 13:39:16 1999  Arnold D. Robbins  <arnold@gnu.org>

        * Makefile.in (gawk): Add $(CFLAGS) to linking step.
        * configure.in: Correctly do AC_FUNC_GETPGRP on HP systems too.

Tue Apr 13 20:21:00 1999  Arnold D. Robbins  <arnold@gnu.org>

        * BETA Release 3.0.43: Release tar file made.

Tue Apr 13 19:02:20 1999  Arnold D. Robbins  <arnold@gnu.org>

        * io.c (useropen, pidopen): Add casts to int on arguments to
          silence gcc warnings.
        * regex.c (regcomp,regexec,regfree): Add ifdef for APPLE.

Thu Feb  4 10:38:02 1999  Arnold D. Robbins  <arnold@gnu.org>

        * custom.h: Hacks for BeOS. Not documented in the manual right now.
        * configure.in: Hacks for BeOS.  Check for HP-UX and define C_ALLOCA
          if not using gcc.  I wish they'd just fix bison already.

Sun Dec 20 16:57:38 1998  Arnold D. Robbins  <arnold@gnu.org>

        * BETA Release 3.0.42: Release tar file made.

Sun Nov 15 21:05:39 1998  Arnold D. Robbins  <arnold@gnu.org>

        * io.c (gawk_popen): Add WIN32 to list of systems that use
          the non-real-pipe version. From the PC gawk guys.

Wed Nov  4 11:32:24 1998  Arnold D. Robbins  <arnold@gnu.org>

        * BETA Release 3.0.41: Release tar file made.

Tue Nov  3 16:24:35 1998  Arnold D. Robbins  <arnold@gnu.org>

        * eval.c (r_get_lhs): Fix the cases for the special variables,
          don't unref their current value if it's the same as the internal
          copy; perhaps the current one is used in a concatenation or some
          other expression somewhere higher up in the call chain.  Ouch.
          See test/getnr2tm.awk.

Sun Nov  1 15:24:52 1998  Arnold D. Robbins  <arnold@gnu.org>

        * builtin.c (format_tree): Improve handling of zero-fill
          when a precision is present. See test/zeroflag.awk.

Wed Oct 28 20:40:17 1998  Arnold D. Robbins  <arnold@gnu.org>

        * eval.c (r_tree_eval): Case for Node_concat. Get lengths
          separately, in case one expression has a side effect that
          that changes another. Ugly, but it keeps gawk from core
          dumping. See test/nasty.awk.

Sun Oct 18 21:27:24 1998  Arnold D. Robbins  <arnold@gnu.org>

        * awk.y (append_right): Bug fix, if `list' or `new' are NULL,
          return `list', so that things don't break too badly.
        * regex.c (re_compile_fastmap): Remove unused variable `num_regs'.

Thu Oct  8 19:36:57 1998  Arnold D. Robbins  <arnold@gnu.org>

        * BETA Release 3.0.40: Release tar file made.

Mon Jul 27 10:14:33 1998  Arnold D. Robbins  <arnold@gnu.org>

        * node.c (parse_escape): Remove assignment with side effects
          from ISXDIGIT test. Thanks to "Mihai T. LAZARESCU"
          <mihai@ccmserv.polito.it> for pointing this out.

Mon Apr 27 11:31:32 1998  Arnold D. Robbins  <arnold@gnu.org>

        * main.c (usage): Fix the email address for the bug list.
          (copyleft): Update the copyright year.

Mon Mar 23 21:22:32 1998  Arnold D. Robbins  <arnold@gnu.org>

        * eval.c (r_get_lhs): Make sure that values of type
          Node_param_list don't have the FUNC flag set. This means
          we don't allow the use of a function name as a variable or
          array from within the function.

Sun Mar 22 19:12:32 1998  Paul Eggert  <eggert@twinsun.com>

        * aclocal.m4 (GAWK_AC_LARGE_FILES): New macro that checks for
          large file support, and updates CPPFLAGS, LDFLAGS, LIBS as
          needed.
        * configure.in: Call GAWK_AC_LARGE_FILES.
        * Makefile.in (CPPFLAGS, LDFLAGS): Let autoconf configure.
        (COMPFLAGS): Add $(CPPFLAGS).

Mon Mar 16 14:06:41 1998  Arnold D. Robbins  <arnold@gnu.org>

        * field.c (using_FIELDWIDTHS): New macro.
          (using_fieldwidths): Use new macro.
          (do_split): In case for FS_DFLT, also check that
          we're not using FIELDWIDTHS. Otherwise, split() would use
          FIELDWIDTHS, not current value of FS. Oops.

Sun Nov 16 20:08:59 1997  Arnold D. Robbins  <arnold@gnu.org>

        * builtin.c (sub_common): Fix for count of matches in gsub
          from Geert.Debyser@esat.kuleuven.ac.be.

Wed Oct 15 03:38:12 1997  Arnold D. Robbins  <arnold@gnu.org>

        * field.c (set_FS): Use `sc_parsefield' if the value of FS is not
          alphabetic OR if not ignoring case. Bug fix if IGNORECASE
          is true and FS happens to be '^'. Sheesh, talk about obscure.
          (rebuild_record): Add more smarts to the code that sets up the
          fields. Thanks to Alan J. Broder (ajb@dtmr.com).

Sun Oct  5 11:56:52 1997  Arnold D. Robbins  <arnold@gnu.org>

        * configure.in: If ISC add -D_SYSV3 to CFLAGS, per email from
          Mario Vanoni (vanonim@dial.eunet.ch).

Fri Sep 26 00:57:49 1997  Arnold D. Robbins  <arnold@gnu.org>

        * awk.y (append_right): Return if either list is NULL. Prevents
          syntax errors from causing core dumps.

Wed Sep 17 15:34:15 1997  Arnold D. Robbins  <arnold@gnu.org>

        * field.c (rebuild_record): Set things up so that all fields point
          into the new record and release any changed fields without
          causing memory leaks.  Avoids problems when fields are extended
          with the value of $0 or other fields and then $0 is assigned to.

Mon Sep 15 16:12:55 1997  Arnold D. Robbins  <arnold@gnu.org>

        * builtin.c (do_print): When testing for NUMBER, make sure
          it's not a string too. Thanks to Michael Brennan for
          clarifying the semantics.

Sun Sep 14 19:55:12 1997  Arnold D. Robbins  <arnold@gnu.org>

        * node.c (format_val): Always format values ourselves: avoids
          problems if OFMT is bizarre, like %s.

Sun Sep 14 00:08:53 1997  Arnold D. Robbins  <arnold@gnu.org>

        * io.c (get_a_record): Replace all occurrences of the test
          `grRS == FALSE' with `RS_is_null' which makes ` RS = "\0" '
          actually work, is clearer code, and actually makes use of
          the `RS_is_null' variable!

Sun Aug 17 07:15:12 1997  Arnold D. Robbins  <arnold@gnu.org>

        * field.c (set_FS): Change logic to always set parse_field, even
          if FS hasn't changed. Thanks to Igor Sheyn for catching this.

Wed Aug  6 21:04:37 1997  Arnold D. Robbins  <arnold@gnu.org>

        * io.c (VMS et al gawk_popen): Use pclose, not fclose, if
          iop_alloc fails.

Wed Jul 30 19:53:52 1997  Arnold D. Robbins  <arnold@gnu.org>

        * awk.y [variable]: Fix case for subscript if $3 == NULL.

Sun Jul 27 22:47:30 1997  Arnold D. Robbins  <arnold@gnu.org>

        * awk.y (get_src_buf): Don't close file if it's stdin.

Sun Jul 27 22:47:15 1997  Pat Rankin  <rankin@eql.caltech.edu>

        * io.c (#if VMS: vmsrtl_fileno): New routine.
          (#if VMS: fileno): New macro substituted for stdio one.

Thu Jul 17 20:05:59 1997  Arnold D. Robbins  <arnold@gnu.org>

        * builtin.c (do_print): When OFMT != CONVFMT, create a new
          temporary node with just the numeric value valid and format it,
          and use that for printing. Avoids memory corruption.

Wed Jul 16 10:01:16 1997  Arnold D. Robbins  <arnold@gnu.org>

        * regex.c: When SYNTAX_TABLE is defined, but not emacs, then
          CHAR_SET_SIZE is not defined, though used in regcomp.  It should
          be taken out of #ifdef SYNTAX_TABLE. Fix from bug group, from
          Akim Demaille, demaille@inf.enst.fr.
        * awk.h (isnondecimal): Make test a little smarter.
        * builtin.c (nondec2awknum): Add bailout for decimal numbers, e.g.
          `00.1'. Fix from Larry Schwimmer <rosebud@cyclone.Stanford.EDU>.

Thu Jun 19 19:00:40 1997  Arnold D. Robbins  <arnold@gnu.org>

        * eval.c (interpret): case Node_K_next, Node_K_nextfile: fatal
          error if called from BEGIN or END.
          (Fixed completely Mon May  3 13:31:42 1999.)

Mon Jun  9 22:40:04 1997  Arnold D. Robbins  <arnold@gnu.org>

        * builtin.c (nondec2awknum): Allow `f' and `F' in hexadecimal numbers.
          Gotta get more sleep...
        * array.c (assoc_lookup): Fix from Tom Karzes (karzes@equator.com)
          for memory leak when forcing type to Node_var_array.

Thu May 15 12:49:08 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * Release 3.0.3: Release tar file made.

Wed May 14 08:06:08 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * io.c (do_close): Add lint warning if closing something that
          isn't open.

Tue May 13 12:14:12 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * random.c, builtin.c: Remove __GLIBC__ tests, since it breaks
          `make test'. I prefer consistency across platforms.
        * Makefile.in (gawk): Undid April 25 changes and added comment.
          Putting COMPLAGS in breaks with -g on VMS POSIX.

          digit day of month should not be zero padded on the 1st through
          the 9th.

Mon May  5 06:33:47 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * io.c (nextfile): Move the check for null return from iop_open
          in the normal case and add one for the "no args" case.

Fri Apr 25 16:52:33 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * array.c (grow_table): Add a bunch more large primes so arrays
          can get really big. Thanks to christos@deshaw.com.
        * all files: Remove ifdef'ed out code and update copyrights.
        * Makefile.in (gawk): Add $(COMPFLAGS) to command line.
        * eval.c (flags2str): Added case for FIELD.

        * COPYING: Changed to current official version from FSF.
        * regex.c: Merge with GLIBC version.
        * awk.h [_GNU_SOURCE]: Bracket definition inside ifdef.
          (NODE.source_line): Move name member out of `x' union and
          into `nodep'; avoids problems doing diagnostics.
          (nondec2num): Put decl into #if BITOPS || NONDECDATA
        * posix/gawkmisc.c, missing/system.c, missing/strtod.c,

        * builtin.c (nondec2num): Put into #if BITOPS || NONDECDATA

Wed Apr 23 22:14:14 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * dfa.c: Misc changes for really pedantic SGI compilers.
        * builtin.c: Bracket defs of random() etc for GLIBC.
        * random.c: Bracket whole file for GLIBC.

Fri Apr 18 07:55:47 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * BETA Release 3.0.34: Release tar file made.

Tue Apr 15 21:35:45 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        NEW UNDOCUMENTED FEATURE. USE THE SOURCE LUKE!
        * acconfig.h [NONDECDATA]: New macro.
        * awk.h: Add decl of do_strtonum.
        * awk.y (tokentab): Add entry for strtonum function.
        * builtin.c (do_strtonum): New function.
        * configure.in (non-decimal-data): New --enable-* option.
        * node.c (r_force_number): Change to allow non-decimal data inside
          ifdef NONDECDATA.

Tue Apr 15 06:32:50 1997  Pat Rankin  <rankin@eql.caltech.edu>

        * missing/strftime.c (malloc, realloc, getenv, strchr): Only
          declare these when STDC_HEADERS is not defined.
          <stdlib.h, string.h>: Include these when STDC_HEADERS is defined.
        * awk.h (freenode, tree_eval, m_tree_eval): Reorganize definitions.
        * alloca.c (malloc): If malloc is already defined as a macro,
          presumeably by config.h, don't define or declare it.

Wed Apr  9 22:45:27 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * Makefile.in [COMPFLAGS]: Per suggestion from Karl Berry, put
          $(CFLAGS) last.

Tue Apr  8 23:54:46 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * eval.c (interpret): For Node_K_break and Node_K_continue, if
          treating them like `next', also check the function call stack
          and pop it if necessary.

Mon Apr  7 18:22:37 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * awk.h: Add decls of new routines do_compl() and set_loc().
        * awk.y (tokentab): Add entry for "compl" function.
        * builtin.c (do_compl): New function to do ones complement.
          (do_substr): Rationalized yet again, now notices negative start
          and length parameters.
        * eval.c (push_args): Fix if call_list gets realloc'ed in the
          middle of things. Avoids crash for deeply nested function calls.
        * main.c (catch_sig): Add call to set_loc().
        * msg.c (set_loc, srcfile, srcline): New function and private
          variables to help out in tracing down source of error messages.

Fri Mar 28 08:42:27 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * io.c (iop_alloc, iop_close): Undo changes of Feb 11, apparently
          other cleanups in io.c made mmap stuff start working again.
          BAH! It's a mess, the test suite still fails. I'm leaving the
          mmap stuff undefined for now. It'll probably get ripped out in 3.1.

Thu Mar 27 08:48:57 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * custom.h [_SEQUENT_]: Undef HAVE_MMAP.

Mon Mar 24 23:09:07 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * field.c (init_fields, etc..): More clean up use of Null_field
          and the various flags.
        * node.c (unref): If a field, free the node itself. Fixes
          memory leak problems.

Sun Mar 23 22:51:09 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * awk.h [FIELD]: New flag for node->flags field.
        * builtin.c (sub_common): If FIELD is set, dup the string.
        * field.c (init_fields): Set up a new Null_field global var.
          (init_fields, set_field, set_record) use the FIELD flag.
          (getfield): Use Null_field instead of private variable.
        * io.c (wait_any): Comment out calls to pclose and iop_close,
          caused weird race conditions. See test/pipeio1.awk. Thanks
          to Darrell Hankerson for tracing this one down.

Tue Mar 18 20:57:18 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * dfa.c (inboth): Free templist; plugs memory leak.
        * field.c (init_fields, grow_fields_arr, set_field, rebuild_record,
          set_record): Remove PERM flag from entries in fields_arr[]. Fixes
          nasty memory leak.

Tue Mar 18 06:33:00 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * awk.y (dup_parms): Robustified against parameter errors.

Sun Mar 16 21:31:40 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        NEW UNDOCUMENTED FEATURE. USE THE SOURCE LUKE!
        * acconfig.h [BITOPS]: New macro. If set, do octal & hex and bit ops.
        * awk.h [isnondecimal]: New macro, and decl of new functions.
        * awk.y (yylex): Add recognition of octal and hex constants.
        * builtin.c (do_and, do_or, do_xor, do_lshift, do_rshift): New
          functions that do bit operations.
          (nondec2awknum): New function to convert octal or hex to double.
        * configure.in: Add AC_ARG_ENABLE for bit operations.
        * node.c (r_force_number): Add octal and hex conversion.

Sun Mar 16 21:28:56 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * awk.h [IOP_NOFREE_OBJ]: New macro.
        * io.c (iop_open, iop_alloc): Add new third parameter, which is
          either NULL, meaning allocate a new IOP, or the address of one
          already allocated.  Have a static one in the `nextfile'
          routine, and use the IOP_NOFREE_OBJ flag for it.  All of this
          keeps us from reading freed memory. The `swaplns' test fails
          otherwise.
          (iop_close): If IOP_NOFREE_OBJ is set, don't free the IOBUF.

Wed Feb 26 06:21:02 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * eval.c (in_function, pop_fcall_stack, pop_fcall, push_args):
          New functions. These manage "frames" of awk function call arguments.
          The problem is that a `next' or a `nextfile' from a function
          leaks memory. These changes allow us to free up that memory.
          (interpret): for Node_K_next and Node_K_nextfile, check if in
          a function call and free all function call frames.

Fri Feb 21 06:23:19 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        Misc changes from Katsuyuki Okabe <HGC02147@niftyserve.or.jp>:

        * builtin.c (do_substr): Change a %d to %ld in warning message.
        * eval.c (op_assign): Fix format string for warning about %=.

Wed Feb 19 23:29:02 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * main.c (main): Add do_intervals to condition that causes
          resetup() to be called again. Makes the --re-interval option
          actually work. What a concept.

Fri Feb 14 09:47:31 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * io.c [#include "awk.h"]: Undef HAVE_MMAP to just use the old code.
          Something is causing a file descriptor leak, and this is getting to
          be just too much hair. I reserve the right to rip out the mmap
          code entirely at a future date.

Tue Feb 11 06:28:29 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * io.c (iop_alloc): For an mmap'ed file, close the file descriptor,
          and then touch each page to get a private copy. Fixes nasty case
          of truncating our input file.
          (iop_close): Don't call close on mmap'ed file.

Wed Feb  5 17:59:04 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * eval.c (interpret): For Node_K_delete, just call do_delete; let
          it handle the case of `delete array'.
        * array.c (do_delete): Changed to handle case of `delete array',
          and made smarter if the array is actually an uninitialized
          parameter.

Sun Jan 26 22:58:29 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * getopt.h, getopt.c, getopt1.c: Replaced with new versions from
          GLIBC 2.

Sun Jan 19 23:37:03 1997  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * eval.c (nodetype2str): Not static, for debugging.
          (flags2str): New function for debugging.
        * field.c (get_field): Add new var that is like Nnull_string but
          does not have numeric attributes, so that new fields are strings.
          (set_record): Turn off PERM flag before unrefing fields and field 0.
        * array.c (in_array): Always evaluate subscript, could have
          side effects.
        * builtin.c (do_strftime): Way increase size of buffer to make sure
          we don't have overflow problem. Keeps Paul Eggert happy.
        * custom.h [__amigaos__]: Define fork to vfork. From Fred Fish.
        * dfa.c: Move include of config.h to top, for RSXNT. From Kai
          Uwe Rommel.
          (ISALPHA, etc): Change from Jacob Engelbrecht (jaen@novo.dk)
          to better handle non-ASCII environments.
        * gawkmisc.c: Remove amigados case, posix should now work fine.
        * amiga/*: Nuked per previous entry.
        * Makefile.in: Removed all references to amiga
        * io.c [HAVE_SYS_PARAM_H]: Add #undef RE_DUP_MAX to avoid
          spurious conflict with regex.h.
          (flush_io): Remove amiga ifdefs, not needed anymore.
          (spec_setup): Set getrec field for special files. Fix from
          Mark Gray (markgray@pdt.net).
        * node.c (more_nodes): Fix to get the last entry in the array.

Wed Jan  8 17:42:37 1997  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

        * io.c (mmap_get_record): Fix return value if file ends without
          record separator.

Fri Jan  3 19:57:16 1997  Pat Rankin  <rankin@eql.caltech.edu>

        * awk.y (get_src_buf):  Test for an empty source file by detecting
          an initial read of 0 bytes rather than by relying on info from
          stat().

Wed Dec 25 11:25:22 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * Release 3.0.2: Release tar file made.

Wed Dec 25 11:17:32 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * Makefile.in (install, uninstall): Use $(srcdir)/patchlevel.h.
          Thanks to Richard Levitte, LeViMS@stacken.kth.se.
          (install): Remove chmod command; let $(INSTALL_PROGRAM) use -m.

Mon Dec 23 20:36:59 1996  Pat Rankin  <rankin@eql.caltech.edu>

        * custom.h (#if VMS_POSIX):  Define GETPGRP_VOID.

Fri Dec 20 08:59:55 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * getopt.c, getopt1.c: Comment out the `#if defined (_LIBC) ||
          !defined (__GNU_LIBRARY__)' and `#endif' to force use of this
          getopt, even on systems like Linux.  This will be handled
          better in 3.1 / glibc 2.

Thu Dec 19 22:52:39 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * awk.y (yylex): In several places, after yyerror(), add call to
          exit(). Otherwise, infinite messages. This should probably
          be handled better.

Wed Dec 18 22:42:10 1996  Darrel Hankerson  <hankedr@mail.auburn.edu>

        * getopt.c (_getopt_internal): If 'W' and ';', if optind == argc,
          return c, don't fall through.

        * configure.in [AC_PREREQ]: Update to 2.12 in order to switch to
          autoconf 2.12. Lots of other files will be rebuilt automatically.
          [AM_SANITY_CHECK_CC]: Removed, autoconf does it now.
        * aclocal.m4 [AM_SANITY_CHECK_CC]: Removed, autoconf does it now.

Tue Dec 17 22:23:16 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * builtin.c (do_strftime): Fix case if format string is "".
          Also fix it if format is not "" but result of strftime is "".
          See comments in code.

Tue Dec 10 23:09:26 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * Release 3.0.1: Release tar file made.

Tue Dec 10 22:39:41 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * Makefile.in (dist): Add dependency on `info'. Remove line that
          does makeinfo.
          (install): Use $(LN) not $(LN_S) to link gawk gawk-version.

Sun Dec  8 07:53:44 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * Makefile.in (gawk): Took COMPFLAGS out of link line for help
          on VMS posix. Shouldn't (I hope) affect anything else.

Thu Nov 28 11:52:24 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * configure.in (AC_PROG_INSTALL): Set INSTALL to install-sh.

Tue Nov 26 22:42:00 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * PORTS: Updated list of systems.
        * Makefile.in (install): Fix some typos and add some improvements
          for Ultrix.

Sun Nov 24 22:16:26 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * builtin.c (do_printf): If no args, fatal error. Return silently
          if --traditional.

Thu Nov  7 20:54:43 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * io.c (inrec): Make sure EOF hasn't already happened before
          trying to read; prevents accessing freed buffer. Thanks to
          Michal Jaegermann.
        * Makefile.in [AWKSRC]: Add random.h.
        * random.h: New file, redefines names of the `random' functions.

        * awk.y (snode): Undo 4 Oct change, put do_split code back.
        * field.c (do_split): Restore old code; add test for CONST, so
          that re_parse_field is used if third arg to split is a regexp
          constant.

Mon Nov  4 12:57:11 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * main.c (main): Research -m[fr] options don't need literal '='
          characters. Brian's documentation was confusing.  Fixed, not
          that anyone actually uses these options with gawk.

Sun Nov  3 11:23:21 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * field.c (def_parse_field): Add \n to list of acceptable white space.
          (posix_def_parse_field): New routine, just like def_parse_field(),
          but only allows space and tab as separators.

Tue Oct 22 21:27:52 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * builtin.c [GAWK_RANDOM_MAX]: Try to make definition a bit
          smarter; don't use RAND_MAX if it's equal to SHRT_MAX, blows
          things up.

Tue Oct 22 08:49:20 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * main.c (copyleft): Update copyright date to 1996.
        * Too many files to list: Update copyright date to 1996.

Sun Oct 20 12:21:09 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * awk.y, dfa.c, eval.c, io.c, re.c: Added various FIXME comments.

Sat Oct 19 22:06:42 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * eval.c (nodetype2str): Make static, add prototype.
        * field.c (sc_parse_field): Cast array subscripts to int to
          shut up gcc warnings.
        * gawkmisc.c: Add prototype for xmalloc.
        * awk.h: Add prototype for getredirect.
        * builtin.c (do_fflush): Remove extern decl of getredirect.
        * io.c (get_a_record, mmap_get_record): Change decl of rs to int,
          to shut up gcc warnings.
        * awk.y (isassignable): Add a default to switch to quiet gcc.
        * getopt.c (_getopt_internal): Give default value to `indfound'.

Fri Oct 18 09:00:49 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * regex.h [RE_SYNTAX_AWK]: Add RE_CONTEXT_INDEP_ANCHORS.

Thu Oct 17 22:32:55 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * aclocal.m4 [AM_SANITY_CHECK_CC]: Added.
        * configure.in: Use it.

Thu Oct 17 21:43:25 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * configure.in: Add checks for locale.h and setlocale().
        * awk.h: Include locale.h and define out setlocale() if not available.
        * main.c (main): Call setlocale().
        * builtin.c (do_tolower, do_toupper): Use unsigned char pointers,
          to get other charsets right in different locales.

Wed Oct 16 21:32:53 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * builtin.c (format_tree): Change initial buffer size to 512
          and use a constant. Allows large values of %f per bug report
          from sheyn@cs.bu.edu.

Wed Oct 16 21:22:08 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * Makefile.in [MISC]: Removed TAGS and tags.
          (local-distclean): Added TAGS and tags.
          (maintainer-clean): Removed TAGS and tags.

Wed Oct 16 12:28:43 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * main.c (version): Add call to copyleft(), per new standards.
          version.c: Fix text of version string to match new standards.

Sun Oct  6 22:19:45 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * regex.c: Updated to Emacs 19.34b base.

Sun Oct  6 21:57:34 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * re.c (make_regexp): Fixed to handle \8 and \9 in the middle
          of a regexp.

Fri Oct  4 10:26:16 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * awk.y (snode): Remove case for do_split; always making the
          third arg a Node_regex is wrong.
        * field.c (do_split): Rationalized to distinguish `/ /' from `" "'.
          Generally fixed up.
        * node.c (parse_escape): Allow single digit \x escapes.

1996-10-02  Paul Eggert  <eggert@twinsun.com>

        * builtin.c (format_tree): Fix bug in %d and %i format: NaNs, and
          values in the range LONG_MAX+1 .. ULONG_MAX, were mishandled.
          Don't assume that double values <= -1 are converted to unsigned
          long in the expected way; the C Standard doesn't guarantee this.

1996-10-02  Paul Eggert  <eggert@twinsun.com>

        * awk.h (INT_MAX): Remove unused symbol.

Mon Sep 30 22:19:11 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * getopt.c (_getopt_internal): If 'W' is in the optstring followed
          by a ';' then search through the long opts table. This makes
          `-W foo=bar' same as `--foo=bar'.
        * main.c (main): 'W' now prints an error message.
          (gawk_option): Deleted the routine.

Sun Sep 29 23:04:54 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * builtin.c (sub_common): Fix several bugs with gsub when
          matching null strings. See test/gsubtest.awk.

Fri Sep 20 17:35:54 1996  Pat Rankin  <rankin@eql.caltech.edu>

        * alloca.c (NULL): Don't define if <config.h> has already done so.

Fri Sep 20 11:54:31 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * builtin.c (do_print): Evaluate all the expressions first and
          then print them. Avoids surprising behavior. See test/prtoeval.awk
          for an example.

Tue Sep 10 06:21:40 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * awk.h [FUNC]: New flag, marks a Node_parameter_list as really
          being the function name; allows more checking in awk.y.
        * awk.y (isassignable): Now takes a NODE * instead of a type, to
          check if a function parameter is marked FUNC, then it's the function
          name, which is not assignable. Fix call from snode().
          (function_prologue): Mark function name as FUNC.
          (yyerror): Don't call exit() anymore; gawk will now report
          all syntax errors.

Sun Sep  1 19:36:30 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * field.c (rebuild_record): After building new field 0, go through
          all old fields, and if they used to point into the old one,
          have them point into the new one.  Then turn off PERM flag before
          unref-ing field 0.

Wed Aug 28 19:13:34 1996  Arnold D. Robbins  <arnold@math.utah.edu>

        * eval.c (set_IGNORECASE): Correctly parenthesize bit operations
          in test and fix logic for string value.

Wed Aug 28 22:06:33 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * main.c (usage): Add email addresses for bug reporting, per
          change in GNU Coding Standards from RMS.

Sun Aug 11 23:13:22 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * Makefile.in (install): Correct use of $(INSTALL_PROGRAM).

Thu Aug  8 23:29:43 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * parse.y (isassignable): New function, checks in type can
          be assigned to.
          (snode): Changed checking for 3rd arg of gsub to be more
          general, supersedes earlier change.

Thu Aug  8 13:58:26 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * parse.y (snode): If third arg to sub or gsub is builtin
          function, complain, since can't substitute into result.
        * eval.c (r_get_lhs): Diagnose Node_builtin as an error, instead
          of falling through into default case and using cant_happen().

Thu Aug  1 07:13:14 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * regex.h [RE_DEBUG]: New macro.
          [RE_SYNTAX_GNU_AWK]: Add RE_DEBUG.
          [RE_SYNTAX_POSIX_AWK]: Add RE_INTERVALS.
        * regex.c (re_set_syntax): Add #ifdef DEBUG code to turn on `debug'
          flag if RE_DEBUG set, and turn off debug if not set and debug
          was on.
        * main.c (main): Remove `do_intervals = TRUE' from `if (do_posix)',
          it's now handled in the definition of RE_SYNTAX_POSIX_AWK.

Mon Jul 29 17:49:07 1996  Pat Rankin  <rankin@eql.caltech.edu>

        * io.c (O_ACCMODE): Define it if <fcntl.h> doesn't.

Mon Jul 29 12:02:48 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * eval.c (set_IGNORECASE): Made somewhat smarter. gawk -v IGNORECASE=0
          was acting the same as -v IGNORECASE=1. Thanks to Darrell Hankerson
          for the bug report.

Fri Jul 26 12:04:43 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * awk.h (format_val): Add declaration of new routine.
        * node.c (format_val): New routine, abstracts old guts of
          r_forcestring; accepts format string and index as additional params.
          (r_force_string): Changed to call format_val.
        * builtin.c (do_print):  Don't tree_eval the tree twice in case
          OFMTidx != CONVFMTidx; doing so could cause side effects
          (from bug report by Tobias Rettstadt, xassp@ipds.uni-kiel.de).
          Instead, call format_val.

Mon Jul 22 21:59:15 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * io.c (iop_close): Change check for "is $0 in the input buffer"
          to use `< (iop->buf + iop->secsiz + iop->size)' instead of
          `< iop->end'. The latter is bogus if EOF has been hit on the
          file.  Fix from Darrel Hankerson based on bug report by
          Charles Howes (howes@grid.direct.ca).  See test/eofsplit.awk.

Thu Jul 18 19:43:20 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * builtin.c (sub_common): Backed out change of Feb 14 in favor of:
          (do_gensub): Changed to use make_string and then to |= TEMP
          flag, based on bug report and patch from Katsuyuki Okabe,
          hgc02147@niftyserve.or.jp.

Thu Jul 18 19:23:53 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * custom.h: Added ifdef for QNX, based on bug report from
          Michael Hunter, mphunter@qnx.com.

Mon Jul 15 09:31:01 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * io.c (redirect): When finding the rp pointer, if it's not
          NULL, set str = rp->value. This gets the '\0' terminated
          version. Motivated by bug report from John Hawkinson
          (jhawk@bbnplanet.com).

Sun Jul 14 18:40:26 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * configure.in: Added call to AC_CHECK_LIB(m, fmod), since
          apparently some systems have fmod in the math library.
          Portability: The Holy Grail.  Sigh.

Sun Jul 14 18:08:01 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * awk.h: Add Jim Meyerings ISASCII etc hacks for ctype macros.
        * builtin.c (do_toupper, do_tolower, sub_common): Changed to use
          upper-case versions of ctype macros.
        * main.c (main): Ditto.
        * node.c (r_force_number, parse_escape): Ditto.

Sun Jul 14 06:34:18 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * field.c (set_record): Made it always do the PERM flag.
          Fixes cases where $0 is assigned to, e.g. by gsub, keeps
          the fields valid.
          (get_field): Removed the call to reset_record in
          case where ! field0_valid. We want to leave the fields alone
          if they've been changed.

Thu Jul 11 23:04:20 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * io.c (devopen): Change tests of (flag & O_fooONLY) to
          (flag & O_ACCMODE) == O_fooONLY. Per (long standing) bug
          report from Chapman Flack.
          (close_redir): Change final conditional to just (status != 0)
          so that ERRNO always set; the warning had its own `if (do_lint)'
          anyway.
        * eval.c (do_split): Force type of array to be Node_var_array
          instead of Node_var.  Per (long standing) bug report from
          Chapman Flack.

Thu Jul 11 22:17:14 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * Makefile.in (install): Added symlink of gawk to awk if
          no awk in $(bindir).
          (LN_S): New variable for symlinking.
          (uninstall): Remove awk if it's the same gawk.
        * Configure.in: Added call to AC_PROG_LN_S for Makefile.in.

Sun Jul  7 15:47:13 1996  Arnold D. Robbins  <arnold@infographix.com>

        * main.c (main): Made `--posix' turn on interval expressions.
          Gawk now matches its documentation. (What a concept!)

Wed Jul  3 15:02:48 1996  Arnold D. Robbins  <arnold@infographix.com>

        * regex.h, regex.c: Upgraded to changes from Emacs 19.31.

Fri May 17 08:46:07 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * io.c (get_a_record): Added `continued' flag. Fix from
          Darrell Hankerson for when RS = "\n|something".

Wed May 15 02:34:55 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * Makefile.in (awklib/all): Now depends on gawk, fixes problem
          with parallel make.

Tue May 14 15:02:52 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * builtin.c (format_tree): Fix handling of '*' to deal with
          negative value for fieldwidth -- make positive and turn on
          left justify. Per bug report from Michael Brennan.

Sun May 12 20:42:06 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * eval.c (r_get_lhs): case Node_subscript. Check if array name
          is actually a function, fatal error if so.

Sun May  5 10:11:52 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * io.c (redirect): Call flush_io() before creating a new output pipe,
          per bug report from Brian Kernighan (bwk@research.bell-labs.com).

Fri Mar 15 06:38:33 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * Makefile.in (install): Use $(INSTALL_PROGRAM), not $(INSTALL).
          (local-distclean): Add `*~' to list of files to be removed.
          (CFLAGS): Now contains just @CFLAGS@.
          (COMPFLAGS): Replaces use of CFLAGS, has CFLAGS plus all the
          other stuff.

Wed Mar 13 14:19:38 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * io.c (mmap_get_record): Fixed to not place sentinel at end
          of mmap'ed object. Won't work if file is exact multiple of
          disk block size. See comments in code for more info.
          Thanks to Rick Adams (rick@uunet.uu.net) for help in testing.

Sun Mar 10 22:50:23 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * io.c (do_close): Notice if we were called as `close(FILENAME)'
          and arrange to close the current input file. This turns out
          to be easy to do, just call `nextfile(TRUE)'. Based on bug report
          from Pascal A. Dupuis, <dupuis@lei.ucl.ac.be>.

Thu Mar  7 08:08:51 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * field.c (init_fields, grow_fields, set_field, rebuild_record):
          Nuke the `nodes' array everywhere.  Anytime a field is unref'ed,
          allocate a new node that is a copy of Nnull_string. This avoids
          subtle memory management problems when doing a lot of assignment
          to fields, and tweaking of NF. Make sure that fields_arr[0] always
          has a type of Node_val!
        * field.c (set_NF): If NF is decremented, clear fields between
          NF and parse_high_water, otherwise if NF incremented, clear
          fields between parse_high_water and NF.
        * eval.c (nodetype2str): New function, used for diagnostics.
          (interpret): Use nodetype2str when finding invalid node.

Mon Mar  4 09:02:28 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * builtin.c (do_toupper, do_tolower): Use isascii along with
          isupper/islower before changing case, in case characters have
          the high bit set. This is a hack.

Mon Feb 26 22:24:44 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * builtin.c (sub_common): If no match, and called from gensub,
          don't free the temporary string, since the tmp_number then
          writes over it.

Sun Feb 25 23:13:01 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * builtin.c (format_tree): Fixed %c to treat user input as
          numeric also by adding test for MAYBE_NUM.

Tue Feb 20 12:25:50 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * configure.in: Added AC_FUNC_MMAP call and add madvise to
          list of functions to look for.
        * awk.h [IOP_ISMAPPED]: New flag value for mmap support and new
          `getrec' structure member in struct iobuf.
        * io.c (iop_alloc, iop_close): Changed to map/unmap input file
          into memory if possible.
          (mmap_get_record): New function to actually retrieve the
          record from mmaped file.

Thu Feb  1 08:56:46 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * builtin.c (do_substr): Fixed lint message to use indx+1 when
          start position is past end of string.

Sun Jan 28 07:00:56 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * builtin.c (do_substr): Rationalized handling of missing length
          argument, as well as various accompanying lint warnings. Previous
          code was slightly bogus. Talk about your Day 1 bugs.

Thu Jan 25 14:09:11 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * builtin.c (do_substr): If length exceeds length of actual
          string, do computation of needed substring length *after*
          the lint warning.

Wed Jan 24 10:06:16 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * Makefile.in (gawk): Add $(CFLAGS) to link line.
          (Makefile): Target depends on the Makefile.in files.
          (OTHERS): Added TAGS and tags to the distribution.
          (local-distclean): New rule.
          (distclean): Use it.
          (maintainer-clean): Don't `make distclean' before running submakes,
          since that removes makefiles needed for the submakes.
        * builtin.c (do_strftime): Remove hard coded limit on length of result.
          Based on code from Paul Eggert (eggert@twinsun.com).

Mon Jan 22 13:16:37 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * main.c (usage): Takes new fp parameter which is either
          stdout for `--help' (per the GNU Coding Standards) or stderr
          if an error occurs. Fix all calls.
          (version): Prints to stdout per the coding stds.
          (copyleft): Prints to stdout now, not stderr, and exits.

Fri Jan 19 08:10:29 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * regex.h [RE_GNU_AWK]: Added RE_CONTEXT_INDEP_OPS to set of
          bits we turn off for regular operation. Breaks things like
          /^+[0-9]+/ to match a literal `+' at the beginning of, say,
          a phone number.

Wed Jan 10 23:19:36 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * 3.0.0 polished up and release tar file made.

Wed Dec 27 11:46:16 1995  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * 2.94.0 released to porting group (no, I haven't been good
          about this file; I'll do better once 3.0 is released).

Mon Aug 28 23:04:30 1995  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * awk.h updated for NeXT - bracket TRUE/FALSE
        * io.c (get_a_record): Removed shadowing of 'start' in
        * Makefile.in and doc/Makefile.in: Fixed to use gawk.1 and gawk.texi,
          instead of gawk.1.in and gawk.texi.in.

Mon Aug 25 11:04:30 1995  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

        * 2.90.0 released to porting group.

Fri Aug 18 12:43:31 1995  Arnold D. Robbins  <arnold@puny.ssc.com>

        * ChangeLog created.
