3821 `51 Franklin Street, Fifth Floor, MA 02110-1301'.
3823 Also, some of the files here were never updated from the previous
3824 '675 Mass Ave, Cambridge, MA 02139', so changed those to the
3825 '51 Franklin Street, Fifth Floor, MA 02110-1301' address too.

3845 (fetch): Get latest gendocs files.
3846 (web-manual): Rewritten to use gendoc for multiformat manuals.

3848 * doc/m4.texinfo (Index): HFS+ (the file system on my Mac) is case
3849 preserving, but case insensitive, so generating html docs per node
3850 clashes between Index.html, the node file, and index.html, the
3851 top-level of the document tree...
3852 (Index macro): ...so renamed to this. Changed all references.

3875 from removing it accidentally again.
3876 * checks/get-them: Allow for trailing spaces tucked behind
3879 2005-03-31 Eric Blake <ebb9@byu.net> (tiny change)

3908 on Windows, so that the frozen file reader will work.
3909 Reported by Josef T. Burger.
3911 * src/m4.c (main): Modernise the --version output.
3913 2005-02-03 Gary V. Vaughan <gary@gnu.org>
3915 Modernise the configury a little to prevent spurious errors from
3916 Autoconf-2.59's autoreconf:
3918 * config.h.in: Renamed to...
3919 * config-h.in: ...this to better support DOS 8.3 file systems.
3920 * acconfig.h: Removed.
3921 * configure.in: Renamed to...
3922 * configure.ac: ...this, and AC_DEFINE used to declare config.h
3923 entry comments. Slight reorganisation and reformatting.

3936 difference between PRODUCT="m4" and PACKAGE="GNU M4".
3937 * configure: Regenerated.
3939 2005-02-03 Noah Misch <noah@cs.caltech.edu>
3941 * src/output.c (mkstemp): Make non-static, and build regardless of
3942 HAVE_TMPFILE; src/builtin.c also needs this replacement.
3945 2004-09-09 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
3947 * configure.in (AC_CHECK_HEADERS): Commit works best when you save
3948 changes from your editor buffer first.
3950 * configure.in (AC_CHECK_HEADERS): Add signal.h, sys/signal.h.
3951 * src/m4.c: And include them as appropriate.
3954 2004-09-09 Andreas Schwab <schwab@suse.de>

3979 * src/output.c (insert_file): Don't assume errno has a valid
3980 value simply because fread returns zero. This fixes a
3981 portability bug reported by Marion Hakanson in
3982 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.

4029 empty file rather than to a nonexistent file. This closes a common
4031 * src/builtin.c (m4_maketemp): Implement the above, by using

4057 * src/macro.c (collect_arguments): Cast obstack arguments to
4058 (voidstar), so avoiding compiler warnings.
4059 Reported by Joseph E. Sacco.

4080 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
4081 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler

4098 * aclocal.m4 (fp_C_PROTOTYPES): Substitute empty or ansi2knr for
4099 ANSI2KNR, depending on the fact the compiler is ANSI or not.
4100 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
4101 Remove the sed filter after ansi2knr for debug.c. Use $O instead
4102 of $U, put underline in extensions rather than in basenames. Use
4103 implicit rules, now that regularity makes this possible.
4104 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
4105 of ansi2knr whenever it is needed.
4106 * configure.in: Adjusted for correct STACKOVF substitution.
4107 * src/debug.c (trace_format): When not __STDC__, use (...) as a

4124 Reported by Jim Kingdon.
4126 * {,/*}Makefile.in: Use && after all cd, in case they fail.
4128 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.
4129 (dist): Use PRODUCT and VERSION instead of tricks on .fname.
4130 * configure.in: Substitute PRODUCT and VERSION.

4187 (realclean): Remove it.
4188 * Makefile.in: Make TAGS in lib also, not just in src.
4189 Reported by Karl Berry.
4191 * Makefile.in (distclean, realclean): Instead of recursively
4192 calling $(MAKE) for the -local part, allow parallel execution of
4193 -recursive and -local, only delay the removal of config.status,
4194 which is repeated in both goals.
4196 Tue Sep 13 19:21:05 1994 Francois Pinard (pinard@icule)
4199 * Makefile.in: Group all *clean-recursive goals in one, using sed
4200 to remove `-recursive' while calling make recursively. Also, use
4201 a subshell for each recursive $(MAKE).
4202 Reported by Jim Meyering.
4204 * src/m4.h (memcpy): Define with bcopy for BSD systems.
4205 Reported by Kaveh R. Ghazi.
4207 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
4208 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
4211 * configure.in: Use date instead of touch for stamp-h.
4212 * Makefile.in (stamp-h.in): Idem.
4214 * Makefile.in (distclean, realclean): Force serial execution of
4215 both goals, in case parallel makes are being used.

4260 Reported by Jim Meyering and John David Anglin.
4262 * Makefile.in (distclean-local): Delete config.log.
4263 Reported by Jim Meyering.
4265 Solidify frozen files with respect to -P:

4267 calling a function by that name. Declare the variable.
4268 * src/m4.h: Adjust declaration for prefix_all_buitins.
4269 * src/builtin.c (builtin_init): Merge in functionality from
4270 previous prefix_all_buitins function, while making entries in the
4271 symbol table, but not modifying the builtin description itself.
4273 * src/freeze.c (reload_frozen_state): Add a useless `break;',
4274 because *many* compilers do not accept an empty `default:'.

4276 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
4278 * configure.in: Use AC_TYPE_SIGNAL.

4285 Reported by Akiko Matsushita and Jim Meyering.
4287 * src/output.c (make_room_for, output_character_helper): New

4289 a per buffer MAXIMUM_BUFFER_SIZE.
4291 * src/output.c (output_text): New function, for optimizing the
4292 output of strings of characters. Use it.

4296 * doc, src: New directories reorganizing the distribution.
4297 * doc/Makefile.in, src/Makefile.in, examples/Makefile.in: New
4299 * Makefile.in: Adjusted.
4300 * configure.in: Configure new Makefiles.
4302 * m4.h: Declare STRING typedef. Use it for comment and quote
4303 strings, adjusting all references. (This is the rudiments of a
4304 beginning for the eventual withdrawal of NUL terminated strings.)
4305 * output.c (shipout_text): Accept a length parameter, and use it.
4306 All callers adjusted.
4308 Mon Aug 29 12:27:19 1994 Francois Pinard (pinard@icule)
4310 * m4.h: Include <unistd.h> if it exists.
4311 * stackovf.c: Don't.
4313 Clean up for current_diversion variable:
4314 * output.c: Move current_diversion from builtin.c.
4315 * m4.h: Declare current_diversion so builtin.c can access it.
4316 * output.c (output_init, make_diversion): Initialize or update
4318 * builtin.c (builtin_init, m4_divert): Leave current_diversion
4321 Remove limit on number of diversions:
4322 * output.c: Replace ndiversion by diversions, declare it.
4323 (output_init): Allocate only diversion 0.
4324 (make_diversion): Allocate new diversions as needed.
4325 * m4.h, m4.c: Remove NDIVERSIONS and ndiversion related stuff.
4326 * m4.c: Still accept -N, but do nothing with it.
4327 Reported by David MacKenzie.
4330 * output.c (freeze_diversions): New function.
4331 * m4.h: Declare freeze_diversions.
4332 * freeze.c: Document frozen file format, revise it, call
4333 freeze_diversions to add diversions to frozen format, and code to
4334 reload them properly.
4335 * m4.c: Do not undivert automatically at end when status being
4336 frozen. Do not call builtin_init when reloading frozen state.
4338 Speed up diversion processing:
4339 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
4340 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
4341 structure and variables, cached variables out of output_diversion,
4342 reallocate_diversion_for and OUTPUT_CHARACTER.
4343 (shipout_text, make_diversion, insert_diversion): Adapted to new
4345 (insert_file): Use better buffering.
4346 Reported by David MacKenzie.
4348 Sun Aug 28 05:20:02 1994 Francois Pinard (pinard@icule)
4350 * Makefile.in, lib/Makefile.in, checks/Makefile.in: Arrange so
4351 dist works from another build directory.
4353 Sat Aug 27 14:32:45 1994 Francois Pinard (pinard@icule)
4355 * symtab.c (hack_all_symbols): Use hash_table_size instead of
4356 constant HASHMAX, for -H option to work better.
4358 * builtin.c (DECLARE): Simplify by using _ ().
4360 * freeze.c: New file.
4361 * Makefile.in: Compile it, distribute it.
4362 * m4.c: Recognize, document and process --freeze-state (-F) and
4363 --reload-state (-R) options. Pass a true flag to builtin_init
4364 only if no reloading some state.
4365 * builtin.c (define_builtin): Remove static specifier.
4366 (find_builtin_by_name): Remove static specifier.
4367 (builtin_init): Accept and obey a flag argument.

4379 Mon Aug 15 12:38:05 1994 Francois Pinard (pinard@icule)
4381 * m4.c (long_options): Use "error-output", the dash was missing.
4382 Reported by Akiko Matsushita.
4384 Fri Aug 12 16:38:01 1994 Francois Pinard (pinard@icule)
4386 * m4.h: Include <sys/types.h>.
4387 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
4388 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
4390 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
4392 * builtin.c (dump_args): Declare len as size_t, not int.
4394 * debug.c: Prototype the forward declaration of debug_set_file.
4396 * builtin.c (m4_undivert): Replace div by file, for avoiding the
4397 shadowing of this variable.
4398 * output.c (insert_diversion): Idem.
4400 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
4401 (input_init): Duplicate default quote and comment strings.
4402 (set_quotes): Free previous quote strings in all cases. Duplicate
4403 even default quote strings.
4404 (set_comment): Free previous comment strings in all cases.
4405 Duplicate even default comment strings.
4407 * configure.in: Updated for Autoconf 2.0.
4408 * Makefile.in (distclean-local): Also delete config.cache.
4410 * m4.c (usage): Reorganize the --help output by topic. Include a
4411 description for debugging flags.
4413 Fri Jul 29 10:15:52 1994 Francois Pinard (pinard@icule)
4415 * configure.in: If sigaction is available and SA_ONSTACK defined,
4416 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
4417 defined, use sigvec. Else don't compile stackovf.c.
4418 * stackovf.c (setup_stackovf_trap): Idem.
4419 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
4422 Thu Jul 21 22:43:17 1994 Francois Pinard (pinard@icule)
4424 * m4.c (usage): Replace printf par fputs.
4426 Mon Jul 18 23:48:23 1994 Francois Pinard (pinard@icule)
4430 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
4432 * configure.in: Check for sigaction and sigvec. Add a new delayed
4433 check for RLIMIT_STACK, combine in the checking for getrlimit.
4434 All those things are not universally available.
4435 * stackovf.c: Split setting up the trap handler and catching
4436 signals, for better taking care of various configure outcomes.
4437 * examples/stackovf.sh: Correct a typo.
4438 Reported by Eric Backus, Jim Avera and Jim Meyering.
4440 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)
4442 * ansi2knr.c: New version sent by its author, Peter Deutsch.
4444 Fri Jul 15 14:36:21 1994 Francois Pinard (pinard@icule)
4446 * Makefile.in: Modify so parallel make will not try making
4447 lib/libm4.a twice simultaneously.
4448 Reported by Jim Meyering.
4450 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
4452 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
4453 error message, for when no code possibility exists. Even if this
4454 line is completely #ifdef'ed out, it brings a syntax error.
4455 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
4457 * Makefile.in (install): Have install depend on all too, for lib
4458 to be remade as needed.
4460 * examples/stackovf.sh: Try ksh, bsh and bash for shells
4461 providing ulimit, instead of using only ksh.
4462 Reported by Jim Avera and Joseph E. Sacco.
4464 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
4466 * Makefile.in (check): Have it depend on all instead of m4. In
4467 this way, a change in lib will be detected and processed.
4469 * builtin.c (numeric_arg): Use strtol and verify the conversion,
4470 instead of using sscanf which stops as soon as there is a
4471 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
4472 and divert(1xyzzy) were all accepted without any warning or error
4474 * m4.h: Declare strtol as long if not including stdlib.h.
4475 * configure.in: Check for limits.h, and replace strtol if missing.
4476 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
4477 * lib/strtol.c: New file, from elsewhere.
4478 Reported by Andreas Schwab.
4480 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
4482 * macro.c (expand_macro): Cast value to (boolean) prior to
4483 assigning it to traced.
4484 Reported by Tom McConnell.
4486 * Makefile.in (m4): Always make all in lib first.
4487 Reported by Jim Meyering.
4489 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
4491 * stackovf.c: Isolated OS-dependent sections; Improved portability,
4492 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
4493 handlers), and a default error message if the fault address is not
4494 available (when neither siginfo.h nor BSD sigcontext are supported).
4495 * configure.in: Changes for stackovf.h: Check for sigcontext,
4496 sigaction, sigstack, and define rlim_t as int if necessary.
4497 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
4498 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
4499 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
4501 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
4503 * configure.in: Use AC_SET_MAKE.
4504 * Makefile.in: Use @SET_MAKE@.
4505 Reported by Jim Meyering.
4507 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
4508 Reported by Ian Taylor.
4510 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
4512 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
4513 because siginfo.h is unrelated to standard headers, and siginfo.h
4514 is already checked for.
4515 Reported by Joseph E. Sacco.
4517 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
4519 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
4522 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
4524 * builtin.c (substitute): Use \& to represent this part of the
4525 string which was matched by the whole regexp, instead of
4526 representing the whole string. Any usage of \0 issues a warning
4527 and acts like \&, it will disappear in some subsequent release.
4529 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
4531 * m4.c: Complete prototype for forwarded declaration of usage.
4533 * input.c (init_macro_token): Correct own reference in error
4534 message. Previous name get_macro_func was referred to instead.
4535 (next_char): Correct own reference in error message. Previous
4536 name advance_input was referred to instead.
4538 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
4539 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
4540 and_term, not_term, logical_not_term, cmp_term, shift_term,
4541 add_term, mult_term, exp_term, unary_term, simple_term): Add
4542 prototype to forwarded declarations. Declare parameter v1 as
4543 eval_t * instead of int *. Same for local variable v2 in dyadic
4544 functions. Same for result in exp_term.
4545 * builtin.c (m4_eval): Declare value as eval_t instead of int.
4546 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
4547 unsigned_eval_t instead of unsigned int. Change casts accordingly.
4548 (shipout_int): Cast first argument of ntoa to eval_t.
4549 Reported by Thorsten Ohl.
4551 * macro.c: Complete the prototypes of forwarded expand_macro and
4553 Reported by Thorsten Ohl.
4555 * m4.h: Define voidstar as void * or char * depending on __STDC__.
4556 The Ultrix 3.1 compiler cannot do much with void pointers.
4558 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
4559 * m4.c (xfree): Replace void * by voidstar.
4560 Reported by Tom McConnell.
4562 * ansi2knr.1: New, from elsewhere.
4563 * Makefile.in (DISTFILES): Distribute ansi2knr.1
4565 * Makefile.in (stamp-h.in): Avoid running ./config.status if
4566 stamp-h does not exist yet. This avoids running it a second time
4567 just after the initial ./configure.
4568 Reported by David MacKenzie and Tom McConnell.
4570 * m4.h: Replace the enum debug_info declaration with a series of
4571 #define's. The Ultrix 3.1 compiler would otherwise need casting
4572 (int) to most references, when used in expressions.
4573 Reported by Tom McConnell.
4575 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
4577 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
4578 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
4579 calls the compiler. Previously, FP_PROTOTYPES was only calling
4580 the preprocessor; by not being subject to CFLAGS, this was
4581 discouraging those flags asking for ANSI compilation.
4582 * acconfig.h: Document HAVE_PROTOTYPES.
4583 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
4584 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
4585 Reported by Eric Backus.
4587 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
4588 from the environment. Default CFLAGS to -g if not set.
4589 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
4590 * lib/Makefile.in: Have CFLAGS substituted from configure.
4591 Reported by Eric Backus and Tom McConnell.
4593 * configure.in: m4_undefine changeword before using AC_ENABLE.
4595 * m4.h: Declare prototypes for error (for ANSI compilers only),
4596 prefix_all_builtins and reference_error.
4597 Reported by Tom McConnell.
4599 * input.c (set_word_regexp): Do not try to initialize the array
4600 test from a string, this does not work with non-ANSI compilers.
4601 Reported by Eric Backus.
4603 * Makefile.in (dist): Clean examples/ before saving it.
4604 (distclean-local): Also remove stamp-h.
4605 Reported by Eric Backus.
4607 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
4609 Reported by Tom McConnell.
4611 * checks/Makefile.in (clean): Depends on mostlyclean.
4612 (mostlyclean): New goal.
4614 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
4616 * Makefile.in (DISTFILES): Distribute install.sh.
4617 * install.sh: New file, copied from elsewhere.
4618 Reported by Assar Westerlund and Kaveh R. Ghazi.
4620 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
4622 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
4623 * acconfig.h: Explain ENABLE_CHANGEWORD.
4625 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
4626 from code provided by Pete Chown]
4627 * m4.h: Add original_text field to u_t variant of union u.
4628 Declare TOKEN_DATA_FUNC macro.
4629 * builtin.c: Declare changeword.
4630 (m4_changeword): New function.
4631 * input.c: Include "regex.h", define variables with word regexps.
4632 (input_init): Initialize the word regexp.
4633 (set_word_regexp): New.
4634 (next_token): Declare local variables, use the previous code if
4635 default_word_regexp is true. Else, match using a new code. Save
4637 * macro.c (expand_token): Ship out original text if not a macro
4639 Reported by Krste Asanovic and Pete Chown.
4641 [These modifs all depend upon ENABLE_CHANGEWORD]
4642 * m4.h: Declare external user_word_regexp.
4643 * m4.c: Declare user_word_regexp, and initialize it from
4644 --word-regexp or -W, or NULL if not specified.
4645 * input.c: Use user_word_regexp if specified, instead of
4646 DEFAULT_WORD_REGEXP.
4648 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
4651 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
4652 * checks/Makefile.in: Empty the suffix list.
4653 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
4655 * m4.c: Declare nesting_limit and initialize it to 250.
4656 Implement -LNUMBER or --nesting-limit=NUMBER to change its
4658 * m4.h: Declare nesting_limit as external.
4659 * macro.c (expand_macro): Stop execution whenever nesting limit
4661 Reported by Bengt Mertensson.
4663 * eval.c (evaluate): Diagnose excess characters in eval input.
4664 Things like `eval(08)' used to return 0 with no diagnostic.
4666 * m4.h: Capitalize first letter of all macro arguments in
4669 * m4.c: Declare warning_status, initialize it to 0. Add new
4670 option -E, or --fatal-warnings, which sets warning_status to
4671 EXIT_FAILURE instead.
4672 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
4673 EXIT_FAILURE if not otherwise done by header files.
4674 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
4675 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
4676 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
4677 argument of all M4ERROR calls.
4678 Reported by Noah Friedman.
4680 * examples/incl-test.m4: Renamed from incl_test.m4.
4681 * examples/include.m4: Include incl-test.m4 instead of
4683 * examples/multiquotes.m4: Renamed from multi-quotes.m.
4685 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
4687 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
4688 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
4689 also tested it on a Sun Sparc workstation running SunOS 4.x.
4691 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
4692 49.format check, abusing a `union values' argument with sprintf
4693 without selecting the proper field. Now, save the formatting type
4694 first, delaying the fetch of the corresponding argument.
4695 Reported by Joseph E. Sacco and Tom Quinn.
4697 * format.c (format): Remove const from char *fmt declaration when
4698 not HAVE_EFGCVT, because a NUL may be forced into it.
4700 * m4.h: Declare atof() when not STDC_HEADERS.
4701 Reported by Joseph E. Sacco.
4703 * Regenerate configure using Autoconf 1.11, this corrects a
4704 problem about an incorrect cpp seting on NeXT 3.1.
4705 Reported by Alexander Lehmann.
4707 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
4709 * m4.h (_): Change argument from `x' to `Args'.
4711 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
4713 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
4714 bringing more evil than good on a few systems.
4715 Reported by Greg A. Woods.
4717 Fri Apr 22 15:59:35 1994 Francois Pinard (pinard@icule)
4719 * m4.h: Rename Args() to _().
4720 * m4.h: Remove extern specifier from all function declarations.
4722 Fri Apr 22 15:51:21 1994 Jim Avera (jima@netcom.com)
4724 * stackovf.c: New file implementing stack-overflow detection.
4725 * configure.in: Check for getrlimit, sigaction. If all of
4726 standard headers, getrlimit and sigaction, define USE_STACKOVF and
4727 substitute ${U}stackovf.o for STACKOVF.
4728 * acconfig.h: Declare USE_STACKOVF.
4729 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
4730 * m4.h: Declare setup_stackovf_trap().
4731 * m4.c: Call setup_stackovf_trap().
4732 * tests/stackovf_test.sh: New file.
4734 Wed Apr 13 14:10:30 1994 Francois Pinard (pinard@icule)
4736 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
4738 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
4740 Sun Jan 30 14:24:19 1994 (pinard at icule)
4742 * m4.h: Remove definition of volatile, not used anymore.
4743 Reported by Jim Meyering and Joseph E. Sacco.
4745 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
4746 of `if ... else /* nothing */' for if macros.
4747 Reported by Jim Meyering.
4749 * builtin.c (m4_regexp): Reorganize the code for avoiding a
4750 warning from gcc about `repl' possibly used before defined.
4751 Reported by Jim Meyering.
4753 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
4754 Reported by Jim Meyering.
4756 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
4758 * m4.h: Move the conditional definition of volatile after the
4759 inclusion of system files, because they may define it first.
4761 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
4763 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
4764 get around a problem with Alpha make seeing a syntax error, there.
4765 Reported by Vern Paxson.
4767 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
4769 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
4770 Reported by Richard Stallman.
4772 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)
4774 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
4775 instead of AC_HAVE_FUNCS.
4776 Reported by Noah Friedman.
4778 Wed Dec 1 09:37:53 1993 Francois Pinard (pinard@icule)
4780 * m4.c: Initialize show_help and show_version to zero.
4782 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
4783 Use them in exit() and usage() calls.
4785 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
4787 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
4788 syserr() macro. Delete errref, add reference_error and M4ERROR.
4789 * m4.c: Replace errref, which was returning an input reference
4790 string, with reference_error, which prints it on standard error.
4791 * builtin.c, output.c: Use errno as second parameter to error,
4792 instead of using syserr() with %s.
4793 * *.c: Use M4ERROR instead of error: no more errref() with %s.
4794 Doing so, the program name appears after the input reference
4795 instead of before, which eases M-x next-error processing.
4797 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
4799 * checks/get-them: Escape braces with backslashes in patterns,
4800 because HPUX-9.01 awk needs this.
4801 Reported by Jim Meyering.
4803 Mon Nov 22 10:55:52 1993 Francois Pinard (pinard@icule)
4805 * builtin.c: Declare "FILE *popen ();".

4808 macros, replace error_message_prefix() declaration by errref()'s.
4809 Declare xrealloc, for use in errref().
4810 * m4.c: Delete error_message_prefix() function, add errref().
4811 * *.c: Use error() systematically in place of all error macros,
4812 now that error() flushes stdout first. Make needed adjustments.
4814 * m4.h: Remove const in sys_errlist[] declaration, it creates
4815 conflicts on SGI and Alpha.
4816 Reported by Kaveh R. Ghazi.
4818 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)

4834 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
4836 * input.c (input_init): Initialize quote and comment strings
4837 explicitely instead of calling set_quotes and set_comment: by
4838 doing so, we ensure we do not free uninitialized variables.

4841 expected is on the left and the obtained on the right.
4843 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR

4867 (trace_format): Use stdarg instead of varargs if __STDC__.
4869 * configure.in: Remove checks for vfprintf and _doprnt. These
4870 implementations use varargs tricks which are not portable enough.

4892 * Makefile.in (m4.dvi): Use m4.texinfo instead of m4.texi.
4893 Reported by Joel Sherrill.
4895 * builtin.c (prefix_all_builtins): Instead of the table size, use
4896 the null entry at end for stopping the loop. It was overwritten.
4897 Reported by Andreas Schwab and Jim Meyering.
4899 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
4900 Reported by Kaveh R. Ghazi.

4922 Reported by Tom McConnell.
4924 Mon Nov 8 12:45:34 1993 Francois Pinard (pinard@icule)
4928 * configure.in: Do not copy check files in the build hierarchy.
4929 * checks/check-them: Identify the m4 version being checked. For
4930 finding m4, look in $PATH instead of in the parent directory.
4931 * Makefile.in (check): Prepend `pwd` to $PATH before checking.
4932 * checks/Makefile.in (.all-stamp): Always create check files in
4933 the source hierarchy, not anymore in the build hierarchy.

5099 Fri Jan 15 16:07:00 1993 Francois Pinard (pinard@icule)
5101 * lib/vfprintf.c: Stolen from Oleo distribution and adapted. The

5151 Sat Dec 19 08:21:34 1992 Francois Pinard (pinard at icule)
5154 This is still a beta release for the future GNU m4 version 1.1.
5156 * lib/alloca.c: New, from elsewhere.
5157 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
5159 * m4.h: Do not define index/rindex if already defined. If
5160 FALSE/TRUE are already defined, do not redefine them, but merely
5161 define boolean typedef to int.
5163 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
5164 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
5165 because some C compilers do not like connectives with #ifdef.
5166 * m4.h: Define `volatile' only if __GNUC__, instead of once for
5167 __GNUC__ and once for __STDC__.
5168 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
5170 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
5171 Makefile dependencies. Without it, make keeps destroying and
5172 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
5174 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
5175 to diversion/DIVERSION, this was a spelling error.
5177 * m4.c: Declare version[], remove #include "version.h".
5178 * version.h: Deleted.
5179 * Makefile.in: Remove references to version.h.
5181 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
5182 production, by using a simpler and more robust algorithm. This
5183 solves the problem of synclines sometimes written in the middle of
5184 an output line. Delete sync_line() and output_lines variable.
5185 * m4.h: Remove sync_line prototype and output_lines declaration.
5186 * input.c (next_char), output.c (shipout_text): Remove references
5188 * input.c (push_file, pop_file): Merely put the value -1 in
5189 output_current_line instead of calling sync_line, for delaying a
5190 single `#line NUM FILE' before next output line. Do not test
5191 for sync_output, because this is unnecessary clutter.
5192 * output.c (make_divertion, insert_divertion): Idem.
5193 * input.c: Rename must_advance_line to start_of_input_line, for
5196 * debug.c (trace_header): Select a new debug line format, which
5197 better complies with GNU standards for formatting error messages.
5198 With option `-dfl', M-x next-error might be used on the output.
5199 * m4.c (vmesg): Adjust format of error output to GNU standards.
5200 * m4.texinfo: Adjust examples for `make check' to work.
5202 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
5203 case for enum debug_info constants, which were all lower case.
5205 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
5207 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
5208 collected patches. I tried a few times using newer regex.[ch], it
5209 mysteriously stopped aborting with this one. Insecure feeling...
5210 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
5212 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
5214 * m4.c: Change `--no-warnings' to `--silent'.
5215 Reported by David MacKenzie.
5217 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
5218 leave it off for now. See comment in m4.c for justification.
5219 Reported by David MacKenzie.
5221 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
5222 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
5224 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
5226 * Makefile.in: Ensure recursive cleaning is done before local
5227 cleaning for all clean goals.
5229 * builtin.c (ntoa): Ensure the value is always interpreted as a
5230 signed quantity, whatever the radix is.
5232 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
5234 * builtin.c, format.c, input.c: Split long lines.
5235 * m4.c: Use typedef macro_definition instead of struct
5237 * symtab.c: Use typedef symbol instead of struct symbol.
5239 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
5241 * *.[ch]: Remove all trailing whitespace, in code and comments.
5243 * configure.in: Find some awk.
5244 * Makefile.in: Add $(AWK) to MDEFINES.
5245 * checks/Makefile.in: Transmit $(AWK) to get_them.
5246 * checks/get_them: Use $AWK instead of gawk. Add a close in the
5247 awk script when switching files, because without this, mawk runs
5248 out of file descriptors.
5250 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
5252 * Makefile.in (realclean): Delete m4.info*.
5253 Reported by Jim Meyering.
5255 * Makefile.in: Adjust and link with checks/Makefile.
5256 * checks/Makefile.in: New.
5257 * configure.in: Output checks/Makefile.
5259 * checks/get_them: Have the dnl header of each test more
5260 recognizable by next-error, also use a better message.
5262 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
5264 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
5265 And use that only if __GNUC__ since we're using it's GCC-specific
5266 semantics that tell the compiler the associated function doesn't
5269 * builtin.c (substitute): Don't use character as an array index.
5270 (dumpdef_cmp): Make formal arguments `const void *' to avoid
5271 warnings with gcc -W -Wall on systems with qsort prototype.
5272 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
5275 * eval.c (most functions): Add parentheses to assignments used
5276 as truth values go avoid warnings from gcc -Wall.
5278 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
5279 any functions that don't need external scope.
5281 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
5282 (many functions and arrays): Declare `const'.
5284 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
5286 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
5287 removing the declaration from m4.h. Also rename false to FALSE
5290 * lib/Makefile.in (Makefile): New goal.
5292 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
5293 so heavily loaded. It gets more easily overridable, calling make.
5294 Reported by Jim Meyering.
5296 * Makefile.in (dist): Get .fname from the current directory name,
5297 instead of from version.h. I need updating many files manually,
5298 when the version changes, version.h is just one of them.
5300 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
5302 * m4.h: Remove the tag `boolean' on the enum introducing typedef
5303 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
5304 Reported by Tom McConnell.
5306 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
5308 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
5309 39.cleardiv, which were describing missing or spurious newlines.
5310 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
5311 do not depend on machine word size, `/bin/false' implementation,
5312 or `wc' output format. `make check' is more dependable, now.
5314 * checks/check_them: Summarize the failed tests by listing their
5315 name, at end. If none, issue `All checks successful'. Output
5316 `Checking' instead of `Input file:'.

5328 enough for triggering reallocation of the obstack chunk, could
5329 void the initialized value of token_buttom, later causing panic in
5330 obstack_free. Rename token_buttom to token_bottom everywhere.
5332 * m4.h: Before declaring errno, first include <errno.h> and
5333 ensure that it does not define errno.
