3786 2005-10-17 John Gatewood Ham <zappaman@buraphalinux.org> (tiny change)
3788 * README: update email address for bug reports.
3790 2005-10-17 Gary V. Vaughan <gary@gnu.org>
3792 * doc/m4.info: Generated files are not kept in the repository.
3794 2005-05-01 Gary V. Vaughan <gary@gnu.org>
3796 The FSF are moving offices today. Changed their contact address
3797 in all files from `59 Temple Place, Suite 330, MA 02111-1307' to
3798 `51 Franklin Street, Fifth Floor, MA 02110-1301'.
3800 Also, some of the files here were never updated from the previous
3801 '675 Mass Ave, Cambridge, MA 02139', so changed those to the
3802 '51 Franklin Street, Fifth Floor, MA 02110-1301' address too.
3804 2005-03-31 Mike Frysinger <vapier@gentoo.org>

3817 * Makefile.maint (TSDEPS_DIST): Remove m4/libtool.m4.
3818 (cvs-news): Look 1 line further down for NEWS release number.

3822 (fetch): Get latest gendocs files.
3823 (web-manual): Rewritten to use gendoc for multiformat manuals.
3824 * doc/gendocs.sh: Don't save an old version in m4 CVS!
3825 * doc/m4.texinfo (Index): HFS+ (the file system on my Mac) is case
3826 preserving, but case insensitive, so generating html docs per node
3827 clashes between Index.html, the node file, and index.html, the
3828 top-level of the document tree...
3829 (Index macro): ...so renamed to this. Changed all references.

3852 from removing it accidentally again.
3853 * checks/get-them: Allow for trailing spaces tucked behind
3856 2005-03-31 Eric Blake <ebb9@byu.net> (tiny change)

3884 * src/freeze.c (produce_frozen_state): Use \n line-endings even
3885 on Windows, so that the frozen file reader will work.
3886 Reported by Josef T. Burger.
3888 * src/m4.c (main): Modernise the --version output.
3890 2005-02-03 Gary V. Vaughan <gary@gnu.org>
3892 Modernise the configury a little to prevent spurious errors from
3893 Autoconf-2.59's autoreconf:
3895 * config.h.in: Renamed to...
3896 * config-h.in: ...this to better support DOS 8.3 file systems.
3897 * acconfig.h: Removed.
3898 * configure.in: Renamed to...
3899 * configure.ac: ...this, and AC_DEFINE used to declare config.h
3900 entry comments. Slight reorganisation and reformatting.

3913 difference between PRODUCT="m4" and PACKAGE="GNU M4".
3914 * configure: Regenerated.
3916 2005-02-03 Noah Misch <noah@cs.caltech.edu>
3918 * src/output.c (mkstemp): Make non-static, and build regardless of
3919 HAVE_TMPFILE; src/builtin.c also needs this replacement.
3922 2004-09-09 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
3924 * configure.in (AC_CHECK_HEADERS): Commit works best when you save
3925 changes from your editor buffer first.
3927 * configure.in (AC_CHECK_HEADERS): Add signal.h, sys/signal.h.
3928 * src/m4.c: And include them as appropriate.
3931 2004-09-09 Andreas Schwab <schwab@suse.de>

3956 * src/output.c (insert_file): Don't assume errno has a valid
3957 value simply because fread returns zero. This fixes a
3958 portability bug reported by Marion Hakanson in
3959 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
3961 2004-06-09 Gary V. Vaughan <gary@gnu.org>

4006 empty file rather than to a nonexistent file. This closes a common
4008 * src/builtin.c (m4_maketemp): Implement the above, by using

4025 be opened, return immediately after producing the error message.
4026 Reported by Andreas Schwab.

4034 * src/macro.c (collect_arguments): Cast obstack arguments to
4035 (voidstar), so avoiding compiler warnings.
4036 Reported by Joseph E. Sacco.

4040 Reported by Joseph E. Sacco.
4042 * src/m4.c (main): Cast the argument to xfree to (voidstar).
4043 * src/symtab.c (free_symbol): Idem.

4057 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
4058 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler

4075 * aclocal.m4 (fp_C_PROTOTYPES): Substitute empty or ansi2knr for
4076 ANSI2KNR, depending on the fact the compiler is ANSI or not.
4077 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
4078 Remove the sed filter after ansi2knr for debug.c. Use $O instead
4079 of $U, put underline in extensions rather than in basenames. Use
4080 implicit rules, now that regularity makes this possible.
4081 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
4082 of ansi2knr whenever it is needed.
4083 * configure.in: Adjusted for correct STACKOVF substitution.
4084 * src/debug.c (trace_format): When not __STDC__, use (...) as a
4085 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.

4098 * Makefile.in: For actions invoking $(MAKE) from within compound
4099 sh statements, exit non-zero if the sub-make fails. Otherwise,
4100 the top-level make may exit successfully when it should fail.
4101 Reported by Jim Kingdon.
4103 * {,/*}Makefile.in: Use && after all cd, in case they fail.
4105 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.
4106 (dist): Use PRODUCT and VERSION instead of tricks on .fname.
4107 * configure.in: Substitute PRODUCT and VERSION.

4111 Thu Oct 27 22:32:58 1994 Francois Pinard (pinard@icule)
4113 * Makefile.in (mostlyclean-local): Do not remove *~.
4114 * */Makefile.in (mostlyclean): Idem.
4115 Reported by Robert E. Brown and Richard Stallman.
4117 Sun Oct 9 08:30:13 1994 Francois Pinard (pinard@icule)

4130 configure does it automatically.
4131 Reported by Jim Meyering.
4133 Fri Sep 23 08:16:58 1994 Francois Pinard (pinard@icule)
4135 * src/stackovf.c: Declare the handler_t typedef earlier in the

4138 casting sigsegv_handler.
4139 Reported by Robert Bernstein.

4164 (realclean): Remove it.
4165 * Makefile.in: Make TAGS in lib also, not just in src.
4166 Reported by Karl Berry.
4168 * Makefile.in (distclean, realclean): Instead of recursively
4169 calling $(MAKE) for the -local part, allow parallel execution of
4170 -recursive and -local, only delay the removal of config.status,
4171 which is repeated in both goals.
4173 Tue Sep 13 19:21:05 1994 Francois Pinard (pinard@icule)
4176 * Makefile.in: Group all *clean-recursive goals in one, using sed
4177 to remove `-recursive' while calling make recursively. Also, use
4178 a subshell for each recursive $(MAKE).
4179 Reported by Jim Meyering.
4181 * src/m4.h (memcpy): Define with bcopy for BSD systems.
4182 Reported by Kaveh R. Ghazi.
4184 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
4185 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
4188 * configure.in: Use date instead of touch for stamp-h.
4189 * Makefile.in (stamp-h.in): Idem.
4191 * Makefile.in (distclean, realclean): Force serial execution of
4192 both goals, in case parallel makes are being used.

4237 Reported by Jim Meyering and John David Anglin.
4239 * Makefile.in (distclean-local): Delete config.log.
4240 Reported by Jim Meyering.
4242 Solidify frozen files with respect to -P:

4244 calling a function by that name. Declare the variable.
4245 * src/m4.h: Adjust declaration for prefix_all_buitins.
4246 * src/builtin.c (builtin_init): Merge in functionality from
4247 previous prefix_all_buitins function, while making entries in the
4248 symbol table, but not modifying the builtin description itself.
4250 * src/freeze.c (reload_frozen_state): Add a useless `break;',
4251 because *many* compilers do not accept an empty `default:'.
4252 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
4253 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
4255 * configure.in: Use AC_TYPE_SIGNAL.

4277 * configure.in: Configure new Makefiles.
4279 * m4.h: Declare STRING typedef. Use it for comment and quote

4281 beginning for the eventual withdrawal of NUL terminated strings.)
4282 * output.c (shipout_text): Accept a length parameter, and use it.
4283 All callers adjusted.
4285 Mon Aug 29 12:27:19 1994 Francois Pinard (pinard@icule)

4302 * m4.h, m4.c: Remove NDIVERSIONS and ndiversion related stuff.
4303 * m4.c: Still accept -N, but do nothing with it.
4304 Reported by David MacKenzie.
4307 * output.c (freeze_diversions): New function.
4308 * m4.h: Declare freeze_diversions.
4309 * freeze.c: Document frozen file format, revise it, call
4310 freeze_diversions to add diversions to frozen format, and code to
4311 reload them properly.
4312 * m4.c: Do not undivert automatically at end when status being
4313 frozen. Do not call builtin_init when reloading frozen state.
4315 Speed up diversion processing:
4316 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
4317 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
4318 structure and variables, cached variables out of output_diversion,
4319 reallocate_diversion_for and OUTPUT_CHARACTER.
4320 (shipout_text, make_diversion, insert_diversion): Adapted to new
4322 (insert_file): Use better buffering.
4323 Reported by David MacKenzie.
4325 Sun Aug 28 05:20:02 1994 Francois Pinard (pinard@icule)
4327 * Makefile.in, lib/Makefile.in, checks/Makefile.in: Arrange so
4328 dist works from another build directory.
4330 Sat Aug 27 14:32:45 1994 Francois Pinard (pinard@icule)
4332 * symtab.c (hack_all_symbols): Use hash_table_size instead of
4333 constant HASHMAX, for -H option to work better.
4335 * builtin.c (DECLARE): Simplify by using _ ().
4337 * freeze.c: New file.
4338 * Makefile.in: Compile it, distribute it.
4339 * m4.c: Recognize, document and process --freeze-state (-F) and
4340 --reload-state (-R) options. Pass a true flag to builtin_init
4341 only if no reloading some state.
4342 * builtin.c (define_builtin): Remove static specifier.
4343 (find_builtin_by_name): Remove static specifier.
4344 (builtin_init): Accept and obey a flag argument.

4353 * acconfig.h: Document WITH_DMALLOC.
4354 * m4.h: Add code for when WITH_DMALLOC.
4356 Mon Aug 15 12:38:05 1994 Francois Pinard (pinard@icule)
4358 * m4.c (long_options): Use "error-output", the dash was missing.
4359 Reported by Akiko Matsushita.
4361 Fri Aug 12 16:38:01 1994 Francois Pinard (pinard@icule)
4363 * m4.h: Include <sys/types.h>.
4364 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
4365 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
4367 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
4369 * builtin.c (dump_args): Declare len as size_t, not int.
4371 * debug.c: Prototype the forward declaration of debug_set_file.
4373 * builtin.c (m4_undivert): Replace div by file, for avoiding the
4374 shadowing of this variable.
4375 * output.c (insert_diversion): Idem.
4377 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
4378 (input_init): Duplicate default quote and comment strings.
4379 (set_quotes): Free previous quote strings in all cases. Duplicate
4380 even default quote strings.
4381 (set_comment): Free previous comment strings in all cases.
4382 Duplicate even default comment strings.
4384 * configure.in: Updated for Autoconf 2.0.
4385 * Makefile.in (distclean-local): Also delete config.cache.
4387 * m4.c (usage): Reorganize the --help output by topic. Include a
4388 description for debugging flags.
4390 Fri Jul 29 10:15:52 1994 Francois Pinard (pinard@icule)
4392 * configure.in: If sigaction is available and SA_ONSTACK defined,
4393 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
4394 defined, use sigvec. Else don't compile stackovf.c.
4395 * stackovf.c (setup_stackovf_trap): Idem.
4396 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
4399 Thu Jul 21 22:43:17 1994 Francois Pinard (pinard@icule)
4401 * m4.c (usage): Replace printf par fputs.
4403 Mon Jul 18 23:48:23 1994 Francois Pinard (pinard@icule)
4407 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
4409 * configure.in: Check for sigaction and sigvec. Add a new delayed
4410 check for RLIMIT_STACK, combine in the checking for getrlimit.
4411 All those things are not universally available.
4412 * stackovf.c: Split setting up the trap handler and catching
4413 signals, for better taking care of various configure outcomes.
4414 * examples/stackovf.sh: Correct a typo.
4415 Reported by Eric Backus, Jim Avera and Jim Meyering.
4417 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)
4419 * ansi2knr.c: New version sent by its author, Peter Deutsch.
4421 Fri Jul 15 14:36:21 1994 Francois Pinard (pinard@icule)
4423 * Makefile.in: Modify so parallel make will not try making
4424 lib/libm4.a twice simultaneously.
4425 Reported by Jim Meyering.
4427 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
4429 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
4430 error message, for when no code possibility exists. Even if this
4431 line is completely #ifdef'ed out, it brings a syntax error.
4432 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
4434 * Makefile.in (install): Have install depend on all too, for lib
4435 to be remade as needed.
4437 * examples/stackovf.sh: Try ksh, bsh and bash for shells
4438 providing ulimit, instead of using only ksh.
4439 Reported by Jim Avera and Joseph E. Sacco.
4441 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
4443 * Makefile.in (check): Have it depend on all instead of m4. In
4444 this way, a change in lib will be detected and processed.
4446 * builtin.c (numeric_arg): Use strtol and verify the conversion,
4447 instead of using sscanf which stops as soon as there is a
4448 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
4449 and divert(1xyzzy) were all accepted without any warning or error
4451 * m4.h: Declare strtol as long if not including stdlib.h.
4452 * configure.in: Check for limits.h, and replace strtol if missing.
4453 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
4454 * lib/strtol.c: New file, from elsewhere.
4455 Reported by Andreas Schwab.
4457 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
4459 * macro.c (expand_macro): Cast value to (boolean) prior to
4460 assigning it to traced.
4461 Reported by Tom McConnell.
4463 * Makefile.in (m4): Always make all in lib first.
4464 Reported by Jim Meyering.
4466 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
4468 * stackovf.c: Isolated OS-dependent sections; Improved portability,
4469 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
4470 handlers), and a default error message if the fault address is not
4471 available (when neither siginfo.h nor BSD sigcontext are supported).
4472 * configure.in: Changes for stackovf.h: Check for sigcontext,
4473 sigaction, sigstack, and define rlim_t as int if necessary.
4474 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
4475 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
4476 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
4478 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
4480 * configure.in: Use AC_SET_MAKE.
4481 * Makefile.in: Use @SET_MAKE@.
4482 Reported by Jim Meyering.
4484 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
4485 Reported by Ian Taylor.
4487 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
4489 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
4490 because siginfo.h is unrelated to standard headers, and siginfo.h
4491 is already checked for.
4492 Reported by Joseph E. Sacco.
4494 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
4496 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
4499 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
4501 * builtin.c (substitute): Use \& to represent this part of the
4502 string which was matched by the whole regexp, instead of
4503 representing the whole string. Any usage of \0 issues a warning
4504 and acts like \&, it will disappear in some subsequent release.
4506 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
4508 * m4.c: Complete prototype for forwarded declaration of usage.
4510 * input.c (init_macro_token): Correct own reference in error
4511 message. Previous name get_macro_func was referred to instead.
4512 (next_char): Correct own reference in error message. Previous
4513 name advance_input was referred to instead.
4515 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
4516 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
4517 and_term, not_term, logical_not_term, cmp_term, shift_term,
4518 add_term, mult_term, exp_term, unary_term, simple_term): Add
4519 prototype to forwarded declarations. Declare parameter v1 as
4520 eval_t * instead of int *. Same for local variable v2 in dyadic
4521 functions. Same for result in exp_term.
4522 * builtin.c (m4_eval): Declare value as eval_t instead of int.
4523 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
4524 unsigned_eval_t instead of unsigned int. Change casts accordingly.
4525 (shipout_int): Cast first argument of ntoa to eval_t.
4526 Reported by Thorsten Ohl.
4528 * macro.c: Complete the prototypes of forwarded expand_macro and
4530 Reported by Thorsten Ohl.
4532 * m4.h: Define voidstar as void * or char * depending on __STDC__.
4533 The Ultrix 3.1 compiler cannot do much with void pointers.
4535 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
4536 * m4.c (xfree): Replace void * by voidstar.
4537 Reported by Tom McConnell.
4539 * ansi2knr.1: New, from elsewhere.
4540 * Makefile.in (DISTFILES): Distribute ansi2knr.1
4542 * Makefile.in (stamp-h.in): Avoid running ./config.status if
4543 stamp-h does not exist yet. This avoids running it a second time
4544 just after the initial ./configure.
4545 Reported by David MacKenzie and Tom McConnell.
4547 * m4.h: Replace the enum debug_info declaration with a series of
4548 #define's. The Ultrix 3.1 compiler would otherwise need casting
4549 (int) to most references, when used in expressions.
4550 Reported by Tom McConnell.
4552 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
4554 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
4555 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
4556 calls the compiler. Previously, FP_PROTOTYPES was only calling
4557 the preprocessor; by not being subject to CFLAGS, this was
4558 discouraging those flags asking for ANSI compilation.
4559 * acconfig.h: Document HAVE_PROTOTYPES.
4560 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
4561 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
4562 Reported by Eric Backus.
4564 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
4565 from the environment. Default CFLAGS to -g if not set.
4566 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
4567 * lib/Makefile.in: Have CFLAGS substituted from configure.
4568 Reported by Eric Backus and Tom McConnell.
4570 * configure.in: m4_undefine changeword before using AC_ENABLE.
4572 * m4.h: Declare prototypes for error (for ANSI compilers only),
4573 prefix_all_builtins and reference_error.
4574 Reported by Tom McConnell.
4576 * input.c (set_word_regexp): Do not try to initialize the array
4577 test from a string, this does not work with non-ANSI compilers.
4578 Reported by Eric Backus.
4580 * Makefile.in (dist): Clean examples/ before saving it.
4581 (distclean-local): Also remove stamp-h.
4582 Reported by Eric Backus.
4584 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
4586 Reported by Tom McConnell.
4588 * checks/Makefile.in (clean): Depends on mostlyclean.
4589 (mostlyclean): New goal.
4591 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
4593 * Makefile.in (DISTFILES): Distribute install.sh.
4594 * install.sh: New file, copied from elsewhere.
4595 Reported by Assar Westerlund and Kaveh R. Ghazi.
4597 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
4599 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
4600 * acconfig.h: Explain ENABLE_CHANGEWORD.
4602 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
4603 from code provided by Pete Chown]
4604 * m4.h: Add original_text field to u_t variant of union u.
4605 Declare TOKEN_DATA_FUNC macro.
4606 * builtin.c: Declare changeword.
4607 (m4_changeword): New function.
4608 * input.c: Include "regex.h", define variables with word regexps.
4609 (input_init): Initialize the word regexp.
4610 (set_word_regexp): New.
4611 (next_token): Declare local variables, use the previous code if
4612 default_word_regexp is true. Else, match using a new code. Save
4614 * macro.c (expand_token): Ship out original text if not a macro
4616 Reported by Krste Asanovic and Pete Chown.
4618 [These modifs all depend upon ENABLE_CHANGEWORD]
4619 * m4.h: Declare external user_word_regexp.
4620 * m4.c: Declare user_word_regexp, and initialize it from
4621 --word-regexp or -W, or NULL if not specified.
4622 * input.c: Use user_word_regexp if specified, instead of
4623 DEFAULT_WORD_REGEXP.
4625 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
4628 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
4629 * checks/Makefile.in: Empty the suffix list.
4630 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
4632 * m4.c: Declare nesting_limit and initialize it to 250.
4633 Implement -LNUMBER or --nesting-limit=NUMBER to change its
4635 * m4.h: Declare nesting_limit as external.
4636 * macro.c (expand_macro): Stop execution whenever nesting limit
4638 Reported by Bengt Mertensson.
4640 * eval.c (evaluate): Diagnose excess characters in eval input.
4641 Things like `eval(08)' used to return 0 with no diagnostic.
4643 * m4.h: Capitalize first letter of all macro arguments in
4646 * m4.c: Declare warning_status, initialize it to 0. Add new
4647 option -E, or --fatal-warnings, which sets warning_status to
4648 EXIT_FAILURE instead.
4649 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
4650 EXIT_FAILURE if not otherwise done by header files.
4651 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
4652 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
4653 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
4654 argument of all M4ERROR calls.
4655 Reported by Noah Friedman.
4657 * examples/incl-test.m4: Renamed from incl_test.m4.
4658 * examples/include.m4: Include incl-test.m4 instead of
4660 * examples/multiquotes.m4: Renamed from multi-quotes.m.
4662 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
4664 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
4665 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
4666 also tested it on a Sun Sparc workstation running SunOS 4.x.
4668 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
4669 49.format check, abusing a `union values' argument with sprintf
4670 without selecting the proper field. Now, save the formatting type
4671 first, delaying the fetch of the corresponding argument.
4672 Reported by Joseph E. Sacco and Tom Quinn.
4674 * format.c (format): Remove const from char *fmt declaration when
4675 not HAVE_EFGCVT, because a NUL may be forced into it.
4677 * m4.h: Declare atof() when not STDC_HEADERS.
4678 Reported by Joseph E. Sacco.
4680 * Regenerate configure using Autoconf 1.11, this corrects a
4681 problem about an incorrect cpp seting on NeXT 3.1.
4682 Reported by Alexander Lehmann.
4684 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
4686 * m4.h (_): Change argument from `x' to `Args'.
4688 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
4690 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
4691 bringing more evil than good on a few systems.
4692 Reported by Greg A. Woods.
4694 Fri Apr 22 15:59:35 1994 Francois Pinard (pinard@icule)
4696 * m4.h: Rename Args() to _().
4697 * m4.h: Remove extern specifier from all function declarations.
4699 Fri Apr 22 15:51:21 1994 Jim Avera (jima@netcom.com)
4701 * stackovf.c: New file implementing stack-overflow detection.
4702 * configure.in: Check for getrlimit, sigaction. If all of
4703 standard headers, getrlimit and sigaction, define USE_STACKOVF and
4704 substitute ${U}stackovf.o for STACKOVF.
4705 * acconfig.h: Declare USE_STACKOVF.
4706 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
4707 * m4.h: Declare setup_stackovf_trap().
4708 * m4.c: Call setup_stackovf_trap().
4709 * tests/stackovf_test.sh: New file.
4711 Wed Apr 13 14:10:30 1994 Francois Pinard (pinard@icule)
4713 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
4715 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
4717 Sun Jan 30 14:24:19 1994 (pinard at icule)
4719 * m4.h: Remove definition of volatile, not used anymore.
4720 Reported by Jim Meyering and Joseph E. Sacco.
4722 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
4723 of `if ... else /* nothing */' for if macros.
4724 Reported by Jim Meyering.
4726 * builtin.c (m4_regexp): Reorganize the code for avoiding a
4727 warning from gcc about `repl' possibly used before defined.
4728 Reported by Jim Meyering.
4730 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
4731 Reported by Jim Meyering.
4733 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
4735 * m4.h: Move the conditional definition of volatile after the
4736 inclusion of system files, because they may define it first.
4738 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
4740 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
4741 get around a problem with Alpha make seeing a syntax error, there.
4742 Reported by Vern Paxson.
4744 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
4746 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
4747 Reported by Richard Stallman.
4749 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)
4751 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
4752 instead of AC_HAVE_FUNCS.
4753 Reported by Noah Friedman.
4755 Wed Dec 1 09:37:53 1993 Francois Pinard (pinard@icule)
4757 * m4.c: Initialize show_help and show_version to zero.
4759 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
4760 Use them in exit() and usage() calls.
4762 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
4764 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
4765 syserr() macro. Delete errref, add reference_error and M4ERROR.
4766 * m4.c: Replace errref, which was returning an input reference
4767 string, with reference_error, which prints it on standard error.
4768 * builtin.c, output.c: Use errno as second parameter to error,
4769 instead of using syserr() with %s.
4770 * *.c: Use M4ERROR instead of error: no more errref() with %s.
4771 Doing so, the program name appears after the input reference
4772 instead of before, which eases M-x next-error processing.
4774 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
4776 * checks/get-them: Escape braces with backslashes in patterns,
4777 because HPUX-9.01 awk needs this.
4778 Reported by Jim Meyering.
4780 Mon Nov 22 10:55:52 1993 Francois Pinard (pinard@icule)
4782 * builtin.c: Declare "FILE *popen ();".
4784 * m4.h: Remove MESSAGE{,1,2}, WARNING1, FATAL{,1}, INTERNAL_ERROR
4785 macros, replace error_message_prefix() declaration by errref()'s.
4786 Declare xrealloc, for use in errref().
4787 * m4.c: Delete error_message_prefix() function, add errref().
4788 * *.c: Use error() systematically in place of all error macros,
4789 now that error() flushes stdout first. Make needed adjustments.
4791 * m4.h: Remove const in sys_errlist[] declaration, it creates
4792 conflicts on SGI and Alpha.
4793 Reported by Kaveh R. Ghazi.
4795 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)
4797 * m4.c: Include <getopt.h> instead of "getopt.h".

4800 * acconfig.h: New, for documenting HAVE_EFGCVT.
4801 * Makefile.in: Distribute acconfig.h, .stamp-h.in and config.h.in,
4802 use them wherever appropriate. Also use -I. for compilations.
4803 * lib/Makefile.in: Use -I.. for compilations.
4804 * *.c: Include <config.h> or "config.h".
4806 * m4.h: Test for HAVE_MEMORY_H instead of NEED_MEMORY_H.

4811 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
4813 * input.c (input_init): Initialize quote and comment strings
4814 explicitely instead of calling set_quotes and set_comment: by
4815 doing so, we ensure we do not free uninitialized variables.
4817 * checks/check-them: Reverse arguments to both diff, so the
4818 expected is on the left and the obtained on the right.
4820 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
4821 macros. Delete declarations for m4error, warning, fatal and
4822 internal_error, add declaration for error_message_prefix.

4826 warning with WARNING*, fatal with FATAL* and internal_error with
4828 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
4829 this is not needed anymore.

4870 Reported by Joel Sherrill.
4872 * builtin.c (prefix_all_builtins): Instead of the table size, use
4873 the null entry at end for stopping the loop. It was overwritten.
4874 Reported by Andreas Schwab and Jim Meyering.
4876 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
4877 Reported by Kaveh R. Ghazi.

4906 * checks/check-them: Identify the m4 version being checked. For
4907 finding m4, look in $PATH instead of in the parent directory.
4908 * Makefile.in (check): Prepend `pwd` to $PATH before checking.
4909 * checks/Makefile.in (.all-stamp): Always create check files in
4910 the source hierarchy, not anymore in the build hierarchy.

5076 Fri Jan 15 16:07:00 1993 Francois Pinard (pinard@icule)
5078 * lib/vfprintf.c: Stolen from Oleo distribution and adapted. The

5094 * Makefile.in: Add DEFS to MDEFINES.
5095 * lib/Makefile.in (.c.o): Remove $(CPPFLAGS).
5096 (libm4.a): Remove the library before creating it.
5097 (distclean): Remove tags and TAGS too.

5104 macro.c, output.c, path.c, symtab.c: Change Copyright from
5105 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.
5107 * examples/divert.m4: Deleted, this bug has been corrected.
5109 * Makefile.in (texclean, mostlyclean): New goals.
5111 * Makefile.in (clean): Remove clutter from ansi2knr.
5112 Reported by Pierre Gaumond.
5113 Reported by Greg A. Woods.
5115 Sun Dec 20 10:40:20 1992 Francois Pinard (pinard at icule)
5117 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user
5118 might well use CFLAGS is s/he needs it.
5120 * Makefile.in: Allow installation of info files from a separate

5128 Sat Dec 19 08:21:34 1992 Francois Pinard (pinard at icule)
5131 This is still a beta release for the future GNU m4 version 1.1.
5133 * lib/alloca.c: New, from elsewhere.
5134 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
5136 * m4.h: Do not define index/rindex if already defined. If
5137 FALSE/TRUE are already defined, do not redefine them, but merely
5138 define boolean typedef to int.
5140 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
5141 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
5142 because some C compilers do not like connectives with #ifdef.
5143 * m4.h: Define `volatile' only if __GNUC__, instead of once for
5144 __GNUC__ and once for __STDC__.
5145 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
5147 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
5148 Makefile dependencies. Without it, make keeps destroying and
5149 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
5151 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
5152 to diversion/DIVERSION, this was a spelling error.
5154 * m4.c: Declare version[], remove #include "version.h".
5155 * version.h: Deleted.
5156 * Makefile.in: Remove references to version.h.
5158 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
5159 production, by using a simpler and more robust algorithm. This
5160 solves the problem of synclines sometimes written in the middle of
5161 an output line. Delete sync_line() and output_lines variable.
5162 * m4.h: Remove sync_line prototype and output_lines declaration.
5163 * input.c (next_char), output.c (shipout_text): Remove references
5165 * input.c (push_file, pop_file): Merely put the value -1 in
5166 output_current_line instead of calling sync_line, for delaying a
5167 single `#line NUM FILE' before next output line. Do not test
5168 for sync_output, because this is unnecessary clutter.
5169 * output.c (make_divertion, insert_divertion): Idem.
5170 * input.c: Rename must_advance_line to start_of_input_line, for
5173 * debug.c (trace_header): Select a new debug line format, which
5174 better complies with GNU standards for formatting error messages.
5175 With option `-dfl', M-x next-error might be used on the output.
5176 * m4.c (vmesg): Adjust format of error output to GNU standards.
5177 * m4.texinfo: Adjust examples for `make check' to work.
5179 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
5180 case for enum debug_info constants, which were all lower case.
5182 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
5184 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
5185 collected patches. I tried a few times using newer regex.[ch], it
5186 mysteriously stopped aborting with this one. Insecure feeling...
5187 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
5189 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
5191 * m4.c: Change `--no-warnings' to `--silent'.
5192 Reported by David MacKenzie.
5194 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
5195 leave it off for now. See comment in m4.c for justification.
5196 Reported by David MacKenzie.
5198 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
5199 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
5201 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
5203 * Makefile.in: Ensure recursive cleaning is done before local
5204 cleaning for all clean goals.
5206 * builtin.c (ntoa): Ensure the value is always interpreted as a
5207 signed quantity, whatever the radix is.
5209 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
5211 * builtin.c, format.c, input.c: Split long lines.
5212 * m4.c: Use typedef macro_definition instead of struct
5214 * symtab.c: Use typedef symbol instead of struct symbol.
5216 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
5218 * *.[ch]: Remove all trailing whitespace, in code and comments.
5220 * configure.in: Find some awk.
5221 * Makefile.in: Add $(AWK) to MDEFINES.
5222 * checks/Makefile.in: Transmit $(AWK) to get_them.
5223 * checks/get_them: Use $AWK instead of gawk. Add a close in the
5224 awk script when switching files, because without this, mawk runs
5225 out of file descriptors.
5227 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
5229 * Makefile.in (realclean): Delete m4.info*.
5230 Reported by Jim Meyering.
5232 * Makefile.in: Adjust and link with checks/Makefile.
5233 * checks/Makefile.in: New.
5234 * configure.in: Output checks/Makefile.
5236 * checks/get_them: Have the dnl header of each test more
5237 recognizable by next-error, also use a better message.
5239 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
5241 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
5242 And use that only if __GNUC__ since we're using it's GCC-specific
5243 semantics that tell the compiler the associated function doesn't
5246 * builtin.c (substitute): Don't use character as an array index.
5247 (dumpdef_cmp): Make formal arguments `const void *' to avoid
5248 warnings with gcc -W -Wall on systems with qsort prototype.
5249 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
5252 * eval.c (most functions): Add parentheses to assignments used
5253 as truth values go avoid warnings from gcc -Wall.
5255 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
5256 any functions that don't need external scope.
5258 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
5259 (many functions and arrays): Declare `const'.
5261 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
5263 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
5264 removing the declaration from m4.h. Also rename false to FALSE
5267 * lib/Makefile.in (Makefile): New goal.
5269 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
5270 so heavily loaded. It gets more easily overridable, calling make.
5271 Reported by Jim Meyering.
5273 * Makefile.in (dist): Get .fname from the current directory name,
5274 instead of from version.h. I need updating many files manually,
5275 when the version changes, version.h is just one of them.
5277 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
5279 * m4.h: Remove the tag `boolean' on the enum introducing typedef
5280 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
5281 Reported by Tom McConnell.
5283 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
5285 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
5286 39.cleardiv, which were describing missing or spurious newlines.
5287 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
5288 do not depend on machine word size, `/bin/false' implementation,
5289 or `wc' output format. `make check' is more dependable, now.
5291 * checks/check_them: Summarize the failed tests by listing their
5292 name, at end. If none, issue `All checks successful'. Output
5293 `Checking' instead of `Input file:'.
5295 * checks/get_them, checks/check_them: Reindented.
5297 * Makefile.in (dist): chmod a+r before making the tar file.
5299 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
5301 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
5303 * input.c (next_token): Reinitialize token_buttom just after using
5304 it as a watermark with obstack_free. Or else, a future token, big
5305 enough for triggering reallocation of the obstack chunk, could
5306 void the initialized value of token_buttom, later causing panic in
5307 obstack_free. Rename token_buttom to token_bottom everywhere.
5309 * m4.h: Before declaring errno, first include <errno.h> and
5310 ensure that it does not define errno.
5311 Reported by Richard Stallman.
5313 Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule)
5315 * builtin.c: Define and use DECLARE macro for builtins.
5317 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
5318 argument, this is a common idiom for introducing long comments.
