3759 empty file rather than to a nonexistent file. This closes a common
3761 * src/builtin.c (m4_maketemp): Implement the above, by using
3762 mkstemp rather than mktemp. (trivial change)
3764 2000-01-09 Akim Demaille <demaille@inf.enst.fr>
3766 * src/builtin.c (expand_ranges): Added break after trailing dash.

3778 be opened, return immediately after producing the error message.
3779 Reported by Andreas Schwab.
3781 * configure.in: Check for const only after having found possible
3782 ANSIfying compiler flags, this is of no use to check it before.
3783 Reported by Alexander Lehmann.
3785 Tue Nov 1 22:02:37 1994 Francois Pinard (pinard@icule)
3787 * src/macro.c (collect_arguments): Cast obstack arguments to
3788 (voidstar), so avoiding compiler warnings.
3789 Reported by Joseph E. Sacco.
3791 * src/freeze.c (produce_frozen_state): Cast printed lengths to
3792 (int) so they correspond to %d format items.
3793 Reported by Joseph E. Sacco.
3795 * src/m4.c (main): Cast the argument to xfree to (voidstar).
3796 * src/symtab.c (free_symbol): Idem.

3808 Sun Oct 30 08:13:03 1994 Francois Pinard (pinard@icule)
3810 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
3811 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
3812 defines __STDC__ to 0, for indicating it is *not* ANSI!
3813 Reported by Kaveh R. Ghazi.

3828 * aclocal.m4 (fp_C_PROTOTYPES): Substitute empty or ansi2knr for
3829 ANSI2KNR, depending on the fact the compiler is ANSI or not.
3830 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
3831 Remove the sed filter after ansi2knr for debug.c. Use $O instead
3832 of $U, put underline in extensions rather than in basenames. Use
3833 implicit rules, now that regularity makes this possible.
3834 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
3835 of ansi2knr whenever it is needed.
3836 * configure.in: Adjusted for correct STACKOVF substitution.
3837 * src/debug.c (trace_format): When not __STDC__, use (...) as a
3838 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.
3839 Reported by David MacKenzie.
3841 * Makefile.in: Remove binprefix. Use transform_name instead.
3842 Reported by David MacKenzie.

3849 * Makefile.in (all, install, uninstall): Depend on Makefile.
3851 * Makefile.in: For actions invoking $(MAKE) from within compound
3852 sh statements, exit non-zero if the sub-make fails. Otherwise,
3853 the top-level make may exit successfully when it should fail.
3854 Reported by Jim Kingdon.
3856 * {,/*}Makefile.in: Use && after all cd, in case they fail.
3858 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.

3864 Thu Oct 27 22:32:58 1994 Francois Pinard (pinard@icule)
3866 * Makefile.in (mostlyclean-local): Do not remove *~.
3867 * */Makefile.in (mostlyclean): Idem.

3923 -recursive and -local, only delay the removal of config.status,
3924 which is repeated in both goals.
3926 Tue Sep 13 19:21:05 1994 Francois Pinard (pinard@icule)
3929 * Makefile.in: Group all *clean-recursive goals in one, using sed
3930 to remove `-recursive' while calling make recursively. Also, use
3931 a subshell for each recursive $(MAKE).
3932 Reported by Jim Meyering.
3934 * src/m4.h (memcpy): Define with bcopy for BSD systems.
3935 Reported by Kaveh R. Ghazi.
3937 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
3938 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
3941 * configure.in: Use date instead of touch for stamp-h.
3942 * Makefile.in (stamp-h.in): Idem.
3944 * Makefile.in (distclean, realclean): Force serial execution of

3972 Reported by Jim Meyering.
3974 Tue Sep 6 12:07:33 1994 Francois Pinard (pinard@icule)
3976 * configure.in: Correct stack overflow detection logic, taking
3977 care of systems having only incomplete implementations (like for

3997 calling a function by that name. Declare the variable.
3998 * src/m4.h: Adjust declaration for prefix_all_buitins.
3999 * src/builtin.c (builtin_init): Merge in functionality from
4000 previous prefix_all_buitins function, while making entries in the
4001 symbol table, but not modifying the builtin description itself.
4003 * src/freeze.c (reload_frozen_state): Add a useless `break;',
4004 because *many* compilers do not accept an empty `default:'.
4005 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
4006 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
4008 * configure.in: Use AC_TYPE_SIGNAL.
4009 * src/stackovf.c (setup_stackovf_trap): Use RETSIGTYPE.

4029 * Makefile.in: Adjusted.
4030 * configure.in: Configure new Makefiles.
4032 * m4.h: Declare STRING typedef. Use it for comment and quote
4033 strings, adjusting all references. (This is the rudiments of a
4034 beginning for the eventual withdrawal of NUL terminated strings.)
4035 * output.c (shipout_text): Accept a length parameter, and use it.
4036 All callers adjusted.
4038 Mon Aug 29 12:27:19 1994 Francois Pinard (pinard@icule)

4061 * m4.h: Declare freeze_diversions.
4062 * freeze.c: Document frozen file format, revise it, call
4063 freeze_diversions to add diversions to frozen format, and code to
4064 reload them properly.
4065 * m4.c: Do not undivert automatically at end when status being
4066 frozen. Do not call builtin_init when reloading frozen state.
4068 Speed up diversion processing:
4069 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
4070 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
4071 structure and variables, cached variables out of output_diversion,
4072 reallocate_diversion_for and OUTPUT_CHARACTER.
4073 (shipout_text, make_diversion, insert_diversion): Adapted to new

4083 Sat Aug 27 14:32:45 1994 Francois Pinard (pinard@icule)
4085 * symtab.c (hack_all_symbols): Use hash_table_size instead of
4086 constant HASHMAX, for -H option to work better.
4088 * builtin.c (DECLARE): Simplify by using _ ().
4090 * freeze.c: New file.
4091 * Makefile.in: Compile it, distribute it.
4092 * m4.c: Recognize, document and process --freeze-state (-F) and
4093 --reload-state (-R) options. Pass a true flag to builtin_init
4094 only if no reloading some state.
4095 * builtin.c (define_builtin): Remove static specifier.
4096 (find_builtin_by_name): Remove static specifier.
4097 (builtin_init): Accept and obey a flag argument.

4160 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
4162 * configure.in: Check for sigaction and sigvec. Add a new delayed
4163 check for RLIMIT_STACK, combine in the checking for getrlimit.
4164 All those things are not universally available.
4165 * stackovf.c: Split setting up the trap handler and catching
4166 signals, for better taking care of various configure outcomes.
4167 * examples/stackovf.sh: Correct a typo.
4168 Reported by Eric Backus, Jim Avera and Jim Meyering.
4170 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)

4178 Reported by Jim Meyering.
4180 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
4182 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
4183 error message, for when no code possibility exists. Even if this
4184 line is completely #ifdef'ed out, it brings a syntax error.
4185 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
4187 * Makefile.in (install): Have install depend on all too, for lib
4188 to be remade as needed.
4190 * examples/stackovf.sh: Try ksh, bsh and bash for shells
4191 providing ulimit, instead of using only ksh.

4194 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
4196 * Makefile.in (check): Have it depend on all instead of m4. In
4197 this way, a change in lib will be detected and processed.
4199 * builtin.c (numeric_arg): Use strtol and verify the conversion,
4200 instead of using sscanf which stops as soon as there is a
4201 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
4202 and divert(1xyzzy) were all accepted without any warning or error
4204 * m4.h: Declare strtol as long if not including stdlib.h.
4205 * configure.in: Check for limits.h, and replace strtol if missing.
4206 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
4207 * lib/strtol.c: New file, from elsewhere.
4208 Reported by Andreas Schwab.

4213 assigning it to traced.
4214 Reported by Tom McConnell.
4216 * Makefile.in (m4): Always make all in lib first.
4217 Reported by Jim Meyering.
4219 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
4221 * stackovf.c: Isolated OS-dependent sections; Improved portability,
4222 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
4223 handlers), and a default error message if the fault address is not
4224 available (when neither siginfo.h nor BSD sigcontext are supported).
4225 * configure.in: Changes for stackovf.h: Check for sigcontext,
4226 sigaction, sigstack, and define rlim_t as int if necessary.
4227 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
4228 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
4229 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
4231 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
4233 * configure.in: Use AC_SET_MAKE.
4234 * Makefile.in: Use @SET_MAKE@.
4235 Reported by Jim Meyering.
4237 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
4238 Reported by Ian Taylor.
4240 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
4242 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
4243 because siginfo.h is unrelated to standard headers, and siginfo.h
4244 is already checked for.
4245 Reported by Joseph E. Sacco.
4247 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
4249 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
4252 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
4254 * builtin.c (substitute): Use \& to represent this part of the
4255 string which was matched by the whole regexp, instead of
4256 representing the whole string. Any usage of \0 issues a warning
4257 and acts like \&, it will disappear in some subsequent release.
4259 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
4261 * m4.c: Complete prototype for forwarded declaration of usage.
4263 * input.c (init_macro_token): Correct own reference in error
4264 message. Previous name get_macro_func was referred to instead.
4265 (next_char): Correct own reference in error message. Previous
4266 name advance_input was referred to instead.
4268 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
4269 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
4270 and_term, not_term, logical_not_term, cmp_term, shift_term,
4271 add_term, mult_term, exp_term, unary_term, simple_term): Add
4272 prototype to forwarded declarations. Declare parameter v1 as
4273 eval_t * instead of int *. Same for local variable v2 in dyadic
4274 functions. Same for result in exp_term.
4275 * builtin.c (m4_eval): Declare value as eval_t instead of int.
4276 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
4277 unsigned_eval_t instead of unsigned int. Change casts accordingly.
4278 (shipout_int): Cast first argument of ntoa to eval_t.
4279 Reported by Thorsten Ohl.
4281 * macro.c: Complete the prototypes of forwarded expand_macro and
4283 Reported by Thorsten Ohl.
4285 * m4.h: Define voidstar as void * or char * depending on __STDC__.
4286 The Ultrix 3.1 compiler cannot do much with void pointers.
4288 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
4289 * m4.c (xfree): Replace void * by voidstar.
4290 Reported by Tom McConnell.
4292 * ansi2knr.1: New, from elsewhere.
4293 * Makefile.in (DISTFILES): Distribute ansi2knr.1
4295 * Makefile.in (stamp-h.in): Avoid running ./config.status if
4296 stamp-h does not exist yet. This avoids running it a second time
4297 just after the initial ./configure.
4298 Reported by David MacKenzie and Tom McConnell.
4300 * m4.h: Replace the enum debug_info declaration with a series of
4301 #define's. The Ultrix 3.1 compiler would otherwise need casting
4302 (int) to most references, when used in expressions.
4303 Reported by Tom McConnell.
4305 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
4307 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
4308 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
4309 calls the compiler. Previously, FP_PROTOTYPES was only calling
4310 the preprocessor; by not being subject to CFLAGS, this was
4311 discouraging those flags asking for ANSI compilation.
4312 * acconfig.h: Document HAVE_PROTOTYPES.
4313 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
4314 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.

4317 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
4318 from the environment. Default CFLAGS to -g if not set.
4319 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
4320 * lib/Makefile.in: Have CFLAGS substituted from configure.
4321 Reported by Eric Backus and Tom McConnell.
4323 * configure.in: m4_undefine changeword before using AC_ENABLE.
4325 * m4.h: Declare prototypes for error (for ANSI compilers only),
4326 prefix_all_builtins and reference_error.
4327 Reported by Tom McConnell.
4329 * input.c (set_word_regexp): Do not try to initialize the array
4330 test from a string, this does not work with non-ANSI compilers.
4331 Reported by Eric Backus.
4333 * Makefile.in (dist): Clean examples/ before saving it.
4334 (distclean-local): Also remove stamp-h.
4335 Reported by Eric Backus.
4337 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
4339 Reported by Tom McConnell.
4341 * checks/Makefile.in (clean): Depends on mostlyclean.
4342 (mostlyclean): New goal.

4346 * Makefile.in (DISTFILES): Distribute install.sh.
4347 * install.sh: New file, copied from elsewhere.
4348 Reported by Assar Westerlund and Kaveh R. Ghazi.

4352 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
4353 * acconfig.h: Explain ENABLE_CHANGEWORD.
4355 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
4356 from code provided by Pete Chown]
4357 * m4.h: Add original_text field to u_t variant of union u.
4358 Declare TOKEN_DATA_FUNC macro.
4359 * builtin.c: Declare changeword.
4360 (m4_changeword): New function.
4361 * input.c: Include "regex.h", define variables with word regexps.
4362 (input_init): Initialize the word regexp.
4363 (set_word_regexp): New.
4364 (next_token): Declare local variables, use the previous code if
4365 default_word_regexp is true. Else, match using a new code. Save
4367 * macro.c (expand_token): Ship out original text if not a macro
4369 Reported by Krste Asanovic and Pete Chown.
4371 [These modifs all depend upon ENABLE_CHANGEWORD]
4372 * m4.h: Declare external user_word_regexp.
4373 * m4.c: Declare user_word_regexp, and initialize it from
4374 --word-regexp or -W, or NULL if not specified.
4375 * input.c: Use user_word_regexp if specified, instead of
4376 DEFAULT_WORD_REGEXP.
4378 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
4381 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
4382 * checks/Makefile.in: Empty the suffix list.
4383 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.

4386 Implement -LNUMBER or --nesting-limit=NUMBER to change its
4388 * m4.h: Declare nesting_limit as external.
4389 * macro.c (expand_macro): Stop execution whenever nesting limit
4391 Reported by Bengt Mertensson.
4393 * eval.c (evaluate): Diagnose excess characters in eval input.
4394 Things like `eval(08)' used to return 0 with no diagnostic.
4396 * m4.h: Capitalize first letter of all macro arguments in
4399 * m4.c: Declare warning_status, initialize it to 0. Add new
4400 option -E, or --fatal-warnings, which sets warning_status to
4401 EXIT_FAILURE instead.
4402 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
4403 EXIT_FAILURE if not otherwise done by header files.
4404 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
4405 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
4406 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
4407 argument of all M4ERROR calls.
4408 Reported by Noah Friedman.
4410 * examples/incl-test.m4: Renamed from incl_test.m4.
4411 * examples/include.m4: Include incl-test.m4 instead of
4413 * examples/multiquotes.m4: Renamed from multi-quotes.m.
4415 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
4417 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
4418 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
4419 also tested it on a Sun Sparc workstation running SunOS 4.x.
4421 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
4422 49.format check, abusing a `union values' argument with sprintf
4423 without selecting the proper field. Now, save the formatting type
4424 first, delaying the fetch of the corresponding argument.
4425 Reported by Joseph E. Sacco and Tom Quinn.
4427 * format.c (format): Remove const from char *fmt declaration when
4428 not HAVE_EFGCVT, because a NUL may be forced into it.
4430 * m4.h: Declare atof() when not STDC_HEADERS.
4431 Reported by Joseph E. Sacco.
4433 * Regenerate configure using Autoconf 1.11, this corrects a
4434 problem about an incorrect cpp seting on NeXT 3.1.
4435 Reported by Alexander Lehmann.
4437 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
4439 * m4.h (_): Change argument from `x' to `Args'.
4441 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
4443 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
4444 bringing more evil than good on a few systems.

4457 substitute ${U}stackovf.o for STACKOVF.
4458 * acconfig.h: Declare USE_STACKOVF.
4459 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
4460 * m4.h: Declare setup_stackovf_trap().
4461 * m4.c: Call setup_stackovf_trap().
4462 * tests/stackovf_test.sh: New file.

4466 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
4468 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
4470 Sun Jan 30 14:24:19 1994 (pinard at icule)
4472 * m4.h: Remove definition of volatile, not used anymore.
4473 Reported by Jim Meyering and Joseph E. Sacco.
4475 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
4476 of `if ... else /* nothing */' for if macros.
4477 Reported by Jim Meyering.
4479 * builtin.c (m4_regexp): Reorganize the code for avoiding a
4480 warning from gcc about `repl' possibly used before defined.
4481 Reported by Jim Meyering.
4483 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
4484 Reported by Jim Meyering.
4486 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
4488 * m4.h: Move the conditional definition of volatile after the
4489 inclusion of system files, because they may define it first.
4491 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
4493 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
4494 get around a problem with Alpha make seeing a syntax error, there.
4495 Reported by Vern Paxson.
4497 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
4499 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
4500 Reported by Richard Stallman.
4502 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)

4505 instead of AC_HAVE_FUNCS.
4506 Reported by Noah Friedman.
4508 Wed Dec 1 09:37:53 1993 Francois Pinard (pinard@icule)
4510 * m4.c: Initialize show_help and show_version to zero.
4512 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
4513 Use them in exit() and usage() calls.
4515 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
4517 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
4518 syserr() macro. Delete errref, add reference_error and M4ERROR.
4519 * m4.c: Replace errref, which was returning an input reference
4520 string, with reference_error, which prints it on standard error.
4521 * builtin.c, output.c: Use errno as second parameter to error,
4522 instead of using syserr() with %s.
4523 * *.c: Use M4ERROR instead of error: no more errref() with %s.
4524 Doing so, the program name appears after the input reference
4525 instead of before, which eases M-x next-error processing.
4527 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
4529 * checks/get-them: Escape braces with backslashes in patterns,
4530 because HPUX-9.01 awk needs this.

4539 Declare xrealloc, for use in errref().
4540 * m4.c: Delete error_message_prefix() function, add errref().
4541 * *.c: Use error() systematically in place of all error macros,
4542 now that error() flushes stdout first. Make needed adjustments.
4544 * m4.h: Remove const in sys_errlist[] declaration, it creates
4545 conflicts on SGI and Alpha.
4546 Reported by Kaveh R. Ghazi.
4548 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)

4564 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
4566 * input.c (input_init): Initialize quote and comment strings
4567 explicitely instead of calling set_quotes and set_comment: by
4568 doing so, we ensure we do not free uninitialized variables.
4570 * checks/check-them: Reverse arguments to both diff, so the
4571 expected is on the left and the obtained on the right.
4573 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
4574 macros. Delete declarations for m4error, warning, fatal and
4575 internal_error, add declaration for error_message_prefix.
4576 * m4.c: Delete m4error, warning, fatal and internal_error
4577 routines, add error_message_prefix routine.
4578 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
4579 warning with WARNING*, fatal with FATAL* and internal_error with
4581 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
4582 this is not needed anymore.
4584 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
4585 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
4586 and debug_message, add declaration for debug_message_prefix.

4588 Delete debug_print and debug_message routines, add
4589 debug_message_prefix routine.
4590 * builtin.c, debug.c: Replace debug_print routine calls with
4591 DEBUG_PRINT* macro calls.

4597 (trace_format): Use stdarg instead of varargs if __STDC__.
4599 * configure.in: Remove checks for vfprintf and _doprnt. These
4600 implementations use varargs tricks which are not portable enough.
4601 * lib/vfprintf.c: Deleted.
4602 * lib/_doprnt.c: Deleted.
4603 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.
4604 Reported by Joel Sherrill.

4623 Reported by Joel Sherrill.
4625 * builtin.c (prefix_all_builtins): Instead of the table size, use
4626 the null entry at end for stopping the loop. It was overwritten.
4627 Reported by Andreas Schwab and Jim Meyering.
4629 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
4630 Reported by Kaveh R. Ghazi.

4817 Sat Feb 6 14:59:22 1993 Francois Pinard (pinard@icule)
4819 * Makefile.in, lib/Makefile.in, check/Makefile.in: In dist goals,
4820 ensure 777 mode for directories, so older tar's will restore file
4823 Sun Jan 17 15:38:05 1993 Francois Pinard (pinard@icule)
4825 * Makefile.in, lib/Makefile.in: Put $(CFLAGS) after $(CPPFLAGS),
4826 so the installer can override automatically configured choices.
4827 Reported by Karl Berry.
4829 Fri Jan 15 16:07:00 1993 Francois Pinard (pinard@icule)
4831 * lib/vfprintf.c: Stolen from Oleo distribution and adapted. The
4832 previous version was not working properly on m68k-hp-bsd4.3.
4833 Reported by Roland McGrath.
4835 * lib/_doprnt.c: Stolen from Oleo distribution.
4836 * configure.in: Check for _doprnt.c if vfprintf.c selected.
4837 * lib/Makefile.in: Distribute _doprnt.c.
4838 Do not distribute regex.[ch].old anymore.
4840 Fri Jan 1 19:42:23 1993 Francois Pinard (pinard at icule)
4842 * Makefile.in, lib/Makefile.in: Reinstate $(CPPFLAGS), use it.
4843 Richard wants it there.
4845 Sun Dec 27 07:01:54 1992 Francois Pinard (pinard at icule)
4847 * Makefile.in: Add DEFS to MDEFINES.
4848 * lib/Makefile.in (.c.o): Remove $(CPPFLAGS).
4849 (libm4.a): Remove the library before creating it.
4850 (distclean): Remove tags and TAGS too.
4852 Wed Dec 23 12:46:55 1992 Francois Pinard (pinard at icule)
4854 * Makefile.in (dvi, m4.dvi): New goals.
4856 * builtin.c, eval.c, format.c, input.c, m4.[ch], m4.texinfo,
4857 macro.c, output.c, path.c, symtab.c: Change Copyright from
4858 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.
4860 * examples/divert.m4: Deleted, this bug has been corrected.
4862 * Makefile.in (texclean, mostlyclean): New goals.
4864 * Makefile.in (clean): Remove clutter from ansi2knr.
4865 Reported by Pierre Gaumond.
4866 Reported by Greg A. Woods.
4868 Sun Dec 20 10:40:20 1992 Francois Pinard (pinard at icule)
4870 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user
4871 might well use CFLAGS is s/he needs it.
4873 * Makefile.in: Allow installation of info files from a separate
4875 Reported by Jason Merrill.
4876 Reported by David MacKenzie.
4877 Reported by Skip Montanaro.
4878 Reported by Erez Zadok.

4881 Sat Dec 19 08:21:34 1992 Francois Pinard (pinard at icule)
4884 This is still a beta release for the future GNU m4 version 1.1.
4886 * lib/alloca.c: New, from elsewhere.
4887 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
4889 * m4.h: Do not define index/rindex if already defined. If
4890 FALSE/TRUE are already defined, do not redefine them, but merely
4891 define boolean typedef to int.
4893 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
4894 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
4895 because some C compilers do not like connectives with #ifdef.
4896 * m4.h: Define `volatile' only if __GNUC__, instead of once for
4897 __GNUC__ and once for __STDC__.
4898 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
4900 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
4901 Makefile dependencies. Without it, make keeps destroying and
4902 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
4904 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
4905 to diversion/DIVERSION, this was a spelling error.
4907 * m4.c: Declare version[], remove #include "version.h".
4908 * version.h: Deleted.
4909 * Makefile.in: Remove references to version.h.
4911 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
4912 production, by using a simpler and more robust algorithm. This
4913 solves the problem of synclines sometimes written in the middle of
4914 an output line. Delete sync_line() and output_lines variable.
4915 * m4.h: Remove sync_line prototype and output_lines declaration.
4916 * input.c (next_char), output.c (shipout_text): Remove references
4918 * input.c (push_file, pop_file): Merely put the value -1 in
4919 output_current_line instead of calling sync_line, for delaying a
4920 single `#line NUM FILE' before next output line. Do not test
4921 for sync_output, because this is unnecessary clutter.
4922 * output.c (make_divertion, insert_divertion): Idem.
4923 * input.c: Rename must_advance_line to start_of_input_line, for
4926 * debug.c (trace_header): Select a new debug line format, which
4927 better complies with GNU standards for formatting error messages.
4928 With option `-dfl', M-x next-error might be used on the output.
4929 * m4.c (vmesg): Adjust format of error output to GNU standards.
4930 * m4.texinfo: Adjust examples for `make check' to work.
4932 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
4933 case for enum debug_info constants, which were all lower case.
4935 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
4937 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
4938 collected patches. I tried a few times using newer regex.[ch], it
4939 mysteriously stopped aborting with this one. Insecure feeling...
4940 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
4942 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
4944 * m4.c: Change `--no-warnings' to `--silent'.
4945 Reported by David MacKenzie.
4947 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
4948 leave it off for now. See comment in m4.c for justification.
4949 Reported by David MacKenzie.
4951 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
4952 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
4954 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
4956 * Makefile.in: Ensure recursive cleaning is done before local
4957 cleaning for all clean goals.
4959 * builtin.c (ntoa): Ensure the value is always interpreted as a
4960 signed quantity, whatever the radix is.
4962 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
4964 * builtin.c, format.c, input.c: Split long lines.
4965 * m4.c: Use typedef macro_definition instead of struct
4967 * symtab.c: Use typedef symbol instead of struct symbol.
4969 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
4971 * *.[ch]: Remove all trailing whitespace, in code and comments.
4973 * configure.in: Find some awk.
4974 * Makefile.in: Add $(AWK) to MDEFINES.
4975 * checks/Makefile.in: Transmit $(AWK) to get_them.
4976 * checks/get_them: Use $AWK instead of gawk. Add a close in the
4977 awk script when switching files, because without this, mawk runs
4978 out of file descriptors.
4980 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
4982 * Makefile.in (realclean): Delete m4.info*.
4983 Reported by Jim Meyering.
4985 * Makefile.in: Adjust and link with checks/Makefile.
4986 * checks/Makefile.in: New.
4987 * configure.in: Output checks/Makefile.
4989 * checks/get_them: Have the dnl header of each test more
4990 recognizable by next-error, also use a better message.
4992 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
4994 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
4995 And use that only if __GNUC__ since we're using it's GCC-specific
4996 semantics that tell the compiler the associated function doesn't
4999 * builtin.c (substitute): Don't use character as an array index.
5000 (dumpdef_cmp): Make formal arguments `const void *' to avoid
5001 warnings with gcc -W -Wall on systems with qsort prototype.
5002 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
5005 * eval.c (most functions): Add parentheses to assignments used
5006 as truth values go avoid warnings from gcc -Wall.
5008 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
5009 any functions that don't need external scope.
5011 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
5012 (many functions and arrays): Declare `const'.
5014 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
5016 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
5017 removing the declaration from m4.h. Also rename false to FALSE
5020 * lib/Makefile.in (Makefile): New goal.
5022 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
5023 so heavily loaded. It gets more easily overridable, calling make.
5024 Reported by Jim Meyering.
5026 * Makefile.in (dist): Get .fname from the current directory name,
5027 instead of from version.h. I need updating many files manually,
5028 when the version changes, version.h is just one of them.
5030 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
5032 * m4.h: Remove the tag `boolean' on the enum introducing typedef
5033 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
5034 Reported by Tom McConnell.
5036 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
5038 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
5039 39.cleardiv, which were describing missing or spurious newlines.
5040 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
5041 do not depend on machine word size, `/bin/false' implementation,
5042 or `wc' output format. `make check' is more dependable, now.
5044 * checks/check_them: Summarize the failed tests by listing their
5045 name, at end. If none, issue `All checks successful'. Output
5046 `Checking' instead of `Input file:'.
5048 * checks/get_them, checks/check_them: Reindented.
5050 * Makefile.in (dist): chmod a+r before making the tar file.
5052 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
5054 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
5056 * input.c (next_token): Reinitialize token_buttom just after using
5057 it as a watermark with obstack_free. Or else, a future token, big
5058 enough for triggering reallocation of the obstack chunk, could
5059 void the initialized value of token_buttom, later causing panic in
5060 obstack_free. Rename token_buttom to token_bottom everywhere.
5062 * m4.h: Before declaring errno, first include <errno.h> and
5063 ensure that it does not define errno.
5064 Reported by Richard Stallman.
5066 Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule)
5068 * builtin.c: Define and use DECLARE macro for builtins.
5070 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
5071 argument, this is a common idiom for introducing long comments.
5073 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
5074 arguments. The last argument was silently ignored.
5076 * m4.c (cmd_error): Add a missing semicolon before va_end().
5078 Tue Nov 10 08:57:05 1992 Francois Pinard (pinard at icule)
5080 * Makefile.in: Now handle protoized sources. Define and use U.
5081 Compile and use ansi2knr with old compilers. Update DISTFILES.
5082 Add `aclocal.m4' to `configure' dependencies.
5083 * ansi2knr.c: New, from Ghostscript distribution.
5084 * configure.in: Define U through FP_PROTOTYPES for old compilers.
5085 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
5086 * aclocal.m4: New, provide FP_PROTOTYPES.
5087 * m4.h: Conditionnaly protoized through Args, save for varags.
5088 * builtin.c: Protoized. Then:
5089 Include <sys/types.h> if size_t is not defined, before "regex.h".
5090 (m4_ifelse): Fetch built-in name properly for diagnostic.
5091 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
5092 (m4_regexp): Add const to `msg' declaration.
5093 (m4_patsubst): Add const to `msg' declaration.
5094 * debug.c: Protoized, save for varargs.
5095 * eval.c: Protoized.
5096 * format.c: Protoized.
5097 * input.c: Protoized.
5098 * m4.c: Protoized, save for varargs. Then:
5099 (xfree): Accept void * instead of char *.
5100 (xmalloc): Return void * instead of char *.
5101 (xrealloc): Accept and return void * instead of char *.
5102 * macro.c: Protoized.
5103 * output.c: Protoized.
5104 * path.c: Protoized. Then cast some (char *) over xmalloc's.
5105 * symtab.c: Protoized.
5107 Fri Nov 6 02:05:21 1992 Francois Pinard (pinard at icule)
5109 * m4.texinfo: Remove directory from diagnostics in 30.include,
5110 51.eval, 56.errprint and 57.m4exit tests.
5112 * m4.h: Remove declarations for int or void system functions, they
5113 cause more conflicting trouble than they make good.
5115 * configure.in: Avoid configuration header file. Add some tests.
5116 * m4.h: Remove #include "config.h".
5117 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
5118 Then, rewritten for better compliance with GNU standards.
5120 Thu Nov 5 12:37:13 1992 Francois Pinard (pinard at icule)
5122 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
5123 because of a misplaced #endif.
5125 * Many *.[hc] files: Correct intra-line spacing here and there,
5126 according to GNU indent 1.6 advice.
5128 * configure.in: New, using Autoconf 1.2.
5129 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.

5139 * version.h: De-automatize, force value in.
5141 * m4.c: Changes in order to use a newer getopt.h.
5142 Reported by David MacKenzie.
5144 * checks/: New name for examples/.
5145 * checks/get_them: New location for etc/get_examples.
5146 * checks/check_them: New location for etc/check_examples.

5154 * Makefile.in (check): Add m4 as dependency.
5156 * m4.c: Accept --no-warnings instead of --no_warnings, and
5157 --no-gnu-extensions instead of --no_gnu_extensions. Make the
5158 usage message more informative.
5159 Reported by David MacKenzie.

5175 Reported by Richard Stallman.
5177 * config/hmake-unicos, config/s-unicos.h: New files.
5178 Reported by Hal Peterson.
5180 * eval.c (exp_term): Have N^0 return 1.
5181 Reported by Michael Fetterman.
