2170 in all files from `59 Temple Place, Suite 330, MA 02111-1307' to
2171 `51 Franklin Street, Fifth Floor, MA 02110-1301'.
2173 Also, some of the files here were never updated from the previous
2174 '675 Mass Ave, Cambridge, MA 02139', so changed those to the
2175 '51 Franklin Street, Fifth Floor, MA 02110-1301' address too.
2177 2005-03-31 Mike Frysinger <vapier@gentoo.org>

2194 (cvs-release): Don't mention manual.html.
2195 (fetch): Get latest gendocs files.
2196 (web-manual): Rewritten to use gendoc for multiformat manuals.
2197 * doc/gendocs.sh: Don't save an old version in m4 CVS!
2198 * doc/m4.texinfo (Index): HFS+ (the file system on my Mac) is case
2199 preserving, but case insensitive, so generating html docs per node
2200 clashes between Index.html, the node file, and index.html, the
2201 top-level of the document tree...
2202 (Index macro): ...so renamed to this. Changed all references.

2225 from removing it accidentally again.
2226 * checks/get-them: Allow for trailing spaces tucked behind
2229 2005-03-31 Eric Blake <ebb9@byu.net> (tiny change)

2257 * src/freeze.c (produce_frozen_state): Use \n line-endings even
2258 on Windows, so that the frozen file reader will work.
2259 Reported by Josef T. Burger.
2261 * src/m4.c (main): Modernise the --version output.
2263 2005-02-03 Gary V. Vaughan <gary@gnu.org>
2265 Modernise the configury a little to prevent spurious errors from
2266 Autoconf-2.59's autoreconf:
2268 * config.h.in: Renamed to...
2269 * config-h.in: ...this to better support DOS 8.3 file systems.
2270 * acconfig.h: Removed.
2271 * configure.in: Renamed to...
2272 * configure.ac: ...this, and AC_DEFINE used to declare config.h
2273 entry comments. Slight reorganisation and reformatting.
2274 * aclocal.m4: Use third argument to AC_DEFINE to declare config.h
2276 (AC_INIT): Use a modern 3 argument call.

2286 difference between PRODUCT="m4" and PACKAGE="GNU M4".
2287 * configure: Regenerated.
2289 2005-02-03 Noah Misch <noah@cs.caltech.edu>
2291 * src/output.c (mkstemp): Make non-static, and build regardless of
2292 HAVE_TMPFILE; src/builtin.c also needs this replacement.
2295 2004-09-09 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
2297 * configure.in (AC_CHECK_HEADERS): Commit works best when you save
2298 changes from your editor buffer first.
2300 * configure.in (AC_CHECK_HEADERS): Add signal.h, sys/signal.h.
2301 * src/m4.c: And include them as appropriate.
2304 2004-09-09 Andreas Schwab <schwab@suse.de>

2327 * src/path.c (path_search): Don't let "free" trash errno when
2329 * src/output.c (insert_file): Don't assume errno has a valid
2330 value simply because fread returns zero. This fixes a
2331 portability bug reported by Marion Hakanson in
2332 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
2334 2004-06-09 Gary V. Vaughan <gary@gnu.org>

2378 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
2379 empty file rather than to a nonexistent file. This closes a common
2381 * src/builtin.c (m4_maketemp): Implement the above, by using
2382 mkstemp rather than mktemp. (trivial change)
2384 2000-01-09 Akim Demaille <demaille@inf.enst.fr>
2386 * src/builtin.c (expand_ranges): Added break after trailing dash.

2398 be opened, return immediately after producing the error message.
2399 Reported by Andreas Schwab.

2407 * src/macro.c (collect_arguments): Cast obstack arguments to
2408 (voidstar), so avoiding compiler warnings.
2409 Reported by Joseph E. Sacco.
2411 * src/freeze.c (produce_frozen_state): Cast printed lengths to
2412 (int) so they correspond to %d format items.
2413 Reported by Joseph E. Sacco.
2415 * src/m4.c (main): Cast the argument to xfree to (voidstar).
2416 * src/symtab.c (free_symbol): Idem.

2430 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
2431 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
2432 defines __STDC__ to 0, for indicating it is *not* ANSI!

2445 Reported by John David Anglin.
2447 * src/ansi2knr.c: New version, sent by Peter Deutsch.
2448 * aclocal.m4 (fp_C_PROTOTYPES): Substitute empty or ansi2knr for
2449 ANSI2KNR, depending on the fact the compiler is ANSI or not.
2450 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
2451 Remove the sed filter after ansi2knr for debug.c. Use $O instead
2452 of $U, put underline in extensions rather than in basenames. Use
2453 implicit rules, now that regularity makes this possible.
2454 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
2455 of ansi2knr whenever it is needed.
2456 * configure.in: Adjusted for correct STACKOVF substitution.
2457 * src/debug.c (trace_format): When not __STDC__, use (...) as a
2458 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.

2469 * Makefile.in (all, install, uninstall): Depend on Makefile.
2471 * Makefile.in: For actions invoking $(MAKE) from within compound
2472 sh statements, exit non-zero if the sub-make fails. Otherwise,
2473 the top-level make may exit successfully when it should fail.
2474 Reported by Jim Kingdon.
2476 * {,/*}Makefile.in: Use && after all cd, in case they fail.
2478 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.
2479 (dist): Use PRODUCT and VERSION instead of tricks on .fname.
2480 * configure.in: Substitute PRODUCT and VERSION.
2482 * {,*/}Makefile.in (dist): Always try a hard link before a copy.
2484 Thu Oct 27 22:32:58 1994 Francois Pinard (pinard@icule)
2486 * Makefile.in (mostlyclean-local): Do not remove *~.
2487 * */Makefile.in (mostlyclean): Idem.
2488 Reported by Robert E. Brown and Richard Stallman.
2490 Sun Oct 9 08:30:13 1994 Francois Pinard (pinard@icule)

2498 Reported by David MacKenzie.
2500 Sat Oct 1 11:22:42 1994 Francois Pinard (pinard@icule)

2503 configure does it automatically.
2504 Reported by Jim Meyering.
2506 Fri Sep 23 08:16:58 1994 Francois Pinard (pinard@icule)
2508 * src/stackovf.c: Declare the handler_t typedef earlier in the

2510 (setup_stackovf_trap): Use RETSIGTYPE instead of void while
2511 casting sigsegv_handler.
2512 Reported by Robert Bernstein.
2514 * src/m4.c (main): Initialize program_name to argv[0] without

2535 * lib/Makefile.in (DISTFILES): Distribute TAGS.
2536 (distclean): Do not remove TAGS.
2537 (realclean): Remove it.
2538 * Makefile.in: Make TAGS in lib also, not just in src.
2539 Reported by Karl Berry.
2541 * Makefile.in (distclean, realclean): Instead of recursively
2542 calling $(MAKE) for the -local part, allow parallel execution of
2543 -recursive and -local, only delay the removal of config.status,
2544 which is repeated in both goals.
2546 Tue Sep 13 19:21:05 1994 Francois Pinard (pinard@icule)
2549 * Makefile.in: Group all *clean-recursive goals in one, using sed
2550 to remove `-recursive' while calling make recursively. Also, use
2551 a subshell for each recursive $(MAKE).
2552 Reported by Jim Meyering.
2554 * src/m4.h (memcpy): Define with bcopy for BSD systems.
2555 Reported by Kaveh R. Ghazi.
2557 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
2558 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
2561 * configure.in: Use date instead of touch for stamp-h.
2562 * Makefile.in (stamp-h.in): Idem.
2564 * Makefile.in (distclean, realclean): Force serial execution of
2565 both goals, in case parallel makes are being used.

2578 Thu Sep 8 15:07:27 1994 Francois Pinard (pinard@icule)
2580 * Makefile.in (MDEFINES): Remove INSTALL substitutions, for
2581 ./install.sh will not be correctly referred to in sub-Makefiles.
2582 Reported by John David Anglin.

2597 care of systems having only incomplete implementations (like for
2598 Pyramid 9820 OSx 5.0d).
2599 Reported by Kaveh R. Ghazi.
2601 * src/Makefile.in (TAGS): Remote -t from etags call.

2607 Wed Aug 31 11:17:21 1994 Francois Pinard (pinard@icule)
2609 * examples/Makefile.in (mostlyclean): Do not depend on texclean.
2610 Reported by Jim Meyering and John David Anglin.
2612 * Makefile.in (distclean-local): Delete config.log.
2613 Reported by Jim Meyering.
2615 Solidify frozen files with respect to -P:
2616 * src/m4.c: Have -P set prefix_all_buitins variable instead of
2617 calling a function by that name. Declare the variable.
2618 * src/m4.h: Adjust declaration for prefix_all_buitins.
2619 * src/builtin.c (builtin_init): Merge in functionality from
2620 previous prefix_all_buitins function, while making entries in the
2621 symbol table, but not modifying the builtin description itself.
2623 * src/freeze.c (reload_frozen_state): Add a useless `break;',
2624 because *many* compilers do not accept an empty `default:'.
2625 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
2626 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
2628 * configure.in: Use AC_TYPE_SIGNAL.
2629 * src/stackovf.c (setup_stackovf_trap): Use RETSIGTYPE.

2635 Reported by Akiko Matsushita and Jim Meyering.
2637 * src/output.c (make_room_for, output_character_helper): New

2639 a per buffer MAXIMUM_BUFFER_SIZE.
2641 * src/output.c (output_text): New function, for optimizing the
2642 output of strings of characters. Use it.

2649 * Makefile.in: Adjusted.
2650 * configure.in: Configure new Makefiles.
2652 * m4.h: Declare STRING typedef. Use it for comment and quote
2653 strings, adjusting all references. (This is the rudiments of a
2654 beginning for the eventual withdrawal of NUL terminated strings.)

2665 * m4.h: Declare current_diversion so builtin.c can access it.
2666 * output.c (output_init, make_diversion): Initialize or update
2668 * builtin.c (builtin_init, m4_divert): Leave current_diversion
2671 Remove limit on number of diversions:
2672 * output.c: Replace ndiversion by diversions, declare it.
2673 (output_init): Allocate only diversion 0.
2674 (make_diversion): Allocate new diversions as needed.
2675 * m4.h, m4.c: Remove NDIVERSIONS and ndiversion related stuff.

2681 * m4.h: Declare freeze_diversions.
2682 * freeze.c: Document frozen file format, revise it, call
2683 freeze_diversions to add diversions to frozen format, and code to
2684 reload them properly.
2685 * m4.c: Do not undivert automatically at end when status being
2686 frozen. Do not call builtin_init when reloading frozen state.
2688 Speed up diversion processing:
2689 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
2690 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
2691 structure and variables, cached variables out of output_diversion,
2692 reallocate_diversion_for and OUTPUT_CHARACTER.
2693 (shipout_text, make_diversion, insert_diversion): Adapted to new

2703 Sat Aug 27 14:32:45 1994 Francois Pinard (pinard@icule)
2705 * symtab.c (hack_all_symbols): Use hash_table_size instead of
2706 constant HASHMAX, for -H option to work better.
2708 * builtin.c (DECLARE): Simplify by using _ ().
2710 * freeze.c: New file.
2711 * Makefile.in: Compile it, distribute it.
2712 * m4.c: Recognize, document and process --freeze-state (-F) and

2729 Mon Aug 15 12:38:05 1994 Francois Pinard (pinard@icule)
2731 * m4.c (long_options): Use "error-output", the dash was missing.
2732 Reported by Akiko Matsushita.
2734 Fri Aug 12 16:38:01 1994 Francois Pinard (pinard@icule)
2736 * m4.h: Include <sys/types.h>.
2737 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
2738 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
2740 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
2742 * builtin.c (dump_args): Declare len as size_t, not int.
2744 * debug.c: Prototype the forward declaration of debug_set_file.
2746 * builtin.c (m4_undivert): Replace div by file, for avoiding the
2747 shadowing of this variable.

2750 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
2751 (input_init): Duplicate default quote and comment strings.
2752 (set_quotes): Free previous quote strings in all cases. Duplicate
2753 even default quote strings.

2760 * m4.c (usage): Reorganize the --help output by topic. Include a
2761 description for debugging flags.
2763 Fri Jul 29 10:15:52 1994 Francois Pinard (pinard@icule)
2765 * configure.in: If sigaction is available and SA_ONSTACK defined,
2766 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
2767 defined, use sigvec. Else don't compile stackovf.c.
2768 * stackovf.c (setup_stackovf_trap): Idem.
2769 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
2772 Thu Jul 21 22:43:17 1994 Francois Pinard (pinard@icule)
2774 * m4.c (usage): Replace printf par fputs.
2776 Mon Jul 18 23:48:23 1994 Francois Pinard (pinard@icule)
2780 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
2782 * configure.in: Check for sigaction and sigvec. Add a new delayed
2783 check for RLIMIT_STACK, combine in the checking for getrlimit.
2784 All those things are not universally available.
2785 * stackovf.c: Split setting up the trap handler and catching
2786 signals, for better taking care of various configure outcomes.
2787 * examples/stackovf.sh: Correct a typo.
2788 Reported by Eric Backus, Jim Avera and Jim Meyering.
2790 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)
2792 * ansi2knr.c: New version sent by its author, Peter Deutsch.
2794 Fri Jul 15 14:36:21 1994 Francois Pinard (pinard@icule)
2796 * Makefile.in: Modify so parallel make will not try making
2797 lib/libm4.a twice simultaneously.
2798 Reported by Jim Meyering.
2800 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
2802 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
2803 error message, for when no code possibility exists. Even if this
2804 line is completely #ifdef'ed out, it brings a syntax error.
2805 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
2807 * Makefile.in (install): Have install depend on all too, for lib
2808 to be remade as needed.
2810 * examples/stackovf.sh: Try ksh, bsh and bash for shells
2811 providing ulimit, instead of using only ksh.
2812 Reported by Jim Avera and Joseph E. Sacco.
2814 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
2816 * Makefile.in (check): Have it depend on all instead of m4. In
2817 this way, a change in lib will be detected and processed.
2819 * builtin.c (numeric_arg): Use strtol and verify the conversion,
2820 instead of using sscanf which stops as soon as there is a
2821 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
2822 and divert(1xyzzy) were all accepted without any warning or error
2824 * m4.h: Declare strtol as long if not including stdlib.h.
2825 * configure.in: Check for limits.h, and replace strtol if missing.
2826 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
2827 * lib/strtol.c: New file, from elsewhere.
2828 Reported by Andreas Schwab.
2830 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
2832 * macro.c (expand_macro): Cast value to (boolean) prior to
2833 assigning it to traced.
2834 Reported by Tom McConnell.
2836 * Makefile.in (m4): Always make all in lib first.
2837 Reported by Jim Meyering.
2839 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
2841 * stackovf.c: Isolated OS-dependent sections; Improved portability,
2842 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
2843 handlers), and a default error message if the fault address is not
2844 available (when neither siginfo.h nor BSD sigcontext are supported).
2845 * configure.in: Changes for stackovf.h: Check for sigcontext,
2846 sigaction, sigstack, and define rlim_t as int if necessary.
2847 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
2848 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
2849 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
2851 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
2853 * configure.in: Use AC_SET_MAKE.
2854 * Makefile.in: Use @SET_MAKE@.
2855 Reported by Jim Meyering.
2857 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
2858 Reported by Ian Taylor.
2860 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
2862 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
2863 because siginfo.h is unrelated to standard headers, and siginfo.h
2864 is already checked for.
2865 Reported by Joseph E. Sacco.
2867 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
2869 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
2872 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
2874 * builtin.c (substitute): Use \& to represent this part of the
2875 string which was matched by the whole regexp, instead of
2876 representing the whole string. Any usage of \0 issues a warning
2877 and acts like \&, it will disappear in some subsequent release.
2879 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
2881 * m4.c: Complete prototype for forwarded declaration of usage.
2883 * input.c (init_macro_token): Correct own reference in error
2884 message. Previous name get_macro_func was referred to instead.
2885 (next_char): Correct own reference in error message. Previous
2886 name advance_input was referred to instead.
2888 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
2889 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
2890 and_term, not_term, logical_not_term, cmp_term, shift_term,
2891 add_term, mult_term, exp_term, unary_term, simple_term): Add
2892 prototype to forwarded declarations. Declare parameter v1 as
2893 eval_t * instead of int *. Same for local variable v2 in dyadic
2894 functions. Same for result in exp_term.
2895 * builtin.c (m4_eval): Declare value as eval_t instead of int.
2896 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
2897 unsigned_eval_t instead of unsigned int. Change casts accordingly.
2898 (shipout_int): Cast first argument of ntoa to eval_t.
2899 Reported by Thorsten Ohl.
2901 * macro.c: Complete the prototypes of forwarded expand_macro and
2903 Reported by Thorsten Ohl.
2905 * m4.h: Define voidstar as void * or char * depending on __STDC__.
2906 The Ultrix 3.1 compiler cannot do much with void pointers.
2908 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
2909 * m4.c (xfree): Replace void * by voidstar.
2910 Reported by Tom McConnell.
2912 * ansi2knr.1: New, from elsewhere.
2913 * Makefile.in (DISTFILES): Distribute ansi2knr.1
2915 * Makefile.in (stamp-h.in): Avoid running ./config.status if
2916 stamp-h does not exist yet. This avoids running it a second time
2917 just after the initial ./configure.
2918 Reported by David MacKenzie and Tom McConnell.
2920 * m4.h: Replace the enum debug_info declaration with a series of
2921 #define's. The Ultrix 3.1 compiler would otherwise need casting
2922 (int) to most references, when used in expressions.
2923 Reported by Tom McConnell.
2925 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
2927 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
2928 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
2929 calls the compiler. Previously, FP_PROTOTYPES was only calling
2930 the preprocessor; by not being subject to CFLAGS, this was
2931 discouraging those flags asking for ANSI compilation.
2932 * acconfig.h: Document HAVE_PROTOTYPES.
2933 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
2934 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
2935 Reported by Eric Backus.
2937 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
2938 from the environment. Default CFLAGS to -g if not set.
2939 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
2940 * lib/Makefile.in: Have CFLAGS substituted from configure.
2941 Reported by Eric Backus and Tom McConnell.
2943 * configure.in: m4_undefine changeword before using AC_ENABLE.
2945 * m4.h: Declare prototypes for error (for ANSI compilers only),
2946 prefix_all_builtins and reference_error.
2947 Reported by Tom McConnell.
2949 * input.c (set_word_regexp): Do not try to initialize the array
2950 test from a string, this does not work with non-ANSI compilers.
2951 Reported by Eric Backus.
2953 * Makefile.in (dist): Clean examples/ before saving it.
2954 (distclean-local): Also remove stamp-h.
2955 Reported by Eric Backus.
2957 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
2959 Reported by Tom McConnell.
2961 * checks/Makefile.in (clean): Depends on mostlyclean.
2962 (mostlyclean): New goal.
2964 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
2966 * Makefile.in (DISTFILES): Distribute install.sh.
2967 * install.sh: New file, copied from elsewhere.
2968 Reported by Assar Westerlund and Kaveh R. Ghazi.
2970 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
2972 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
2973 * acconfig.h: Explain ENABLE_CHANGEWORD.
2975 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
2976 from code provided by Pete Chown]
2977 * m4.h: Add original_text field to u_t variant of union u.
2978 Declare TOKEN_DATA_FUNC macro.
2979 * builtin.c: Declare changeword.
2980 (m4_changeword): New function.
2981 * input.c: Include "regex.h", define variables with word regexps.
2982 (input_init): Initialize the word regexp.
2983 (set_word_regexp): New.
2984 (next_token): Declare local variables, use the previous code if
2985 default_word_regexp is true. Else, match using a new code. Save
2987 * macro.c (expand_token): Ship out original text if not a macro
2989 Reported by Krste Asanovic and Pete Chown.
2991 [These modifs all depend upon ENABLE_CHANGEWORD]
2992 * m4.h: Declare external user_word_regexp.
2993 * m4.c: Declare user_word_regexp, and initialize it from
2994 --word-regexp or -W, or NULL if not specified.
2995 * input.c: Use user_word_regexp if specified, instead of
2996 DEFAULT_WORD_REGEXP.
2998 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
3001 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
3002 * checks/Makefile.in: Empty the suffix list.
3003 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
3005 * m4.c: Declare nesting_limit and initialize it to 250.
3006 Implement -LNUMBER or --nesting-limit=NUMBER to change its
3008 * m4.h: Declare nesting_limit as external.
3009 * macro.c (expand_macro): Stop execution whenever nesting limit
3011 Reported by Bengt Mertensson.
3013 * eval.c (evaluate): Diagnose excess characters in eval input.
3014 Things like `eval(08)' used to return 0 with no diagnostic.
3016 * m4.h: Capitalize first letter of all macro arguments in
3019 * m4.c: Declare warning_status, initialize it to 0. Add new
3020 option -E, or --fatal-warnings, which sets warning_status to
3021 EXIT_FAILURE instead.
3022 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
3023 EXIT_FAILURE if not otherwise done by header files.
3024 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
3025 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
3026 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
3027 argument of all M4ERROR calls.
3028 Reported by Noah Friedman.
3030 * examples/incl-test.m4: Renamed from incl_test.m4.
3031 * examples/include.m4: Include incl-test.m4 instead of
3033 * examples/multiquotes.m4: Renamed from multi-quotes.m.
3035 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
3037 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
3038 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
3039 also tested it on a Sun Sparc workstation running SunOS 4.x.
3041 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
3042 49.format check, abusing a `union values' argument with sprintf
3043 without selecting the proper field. Now, save the formatting type
3044 first, delaying the fetch of the corresponding argument.
3045 Reported by Joseph E. Sacco and Tom Quinn.
3047 * format.c (format): Remove const from char *fmt declaration when
3048 not HAVE_EFGCVT, because a NUL may be forced into it.
3050 * m4.h: Declare atof() when not STDC_HEADERS.
3051 Reported by Joseph E. Sacco.
3053 * Regenerate configure using Autoconf 1.11, this corrects a
3054 problem about an incorrect cpp seting on NeXT 3.1.
3055 Reported by Alexander Lehmann.
3057 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
3059 * m4.h (_): Change argument from `x' to `Args'.
3061 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
3063 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
3064 bringing more evil than good on a few systems.
3065 Reported by Greg A. Woods.
3067 Fri Apr 22 15:59:35 1994 Francois Pinard (pinard@icule)
3069 * m4.h: Rename Args() to _().

3072 Fri Apr 22 15:51:21 1994 Jim Avera (jima@netcom.com)
3074 * stackovf.c: New file implementing stack-overflow detection.
3075 * configure.in: Check for getrlimit, sigaction. If all of
3076 standard headers, getrlimit and sigaction, define USE_STACKOVF and
3077 substitute ${U}stackovf.o for STACKOVF.
3078 * acconfig.h: Declare USE_STACKOVF.
3079 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
3080 * m4.h: Declare setup_stackovf_trap().
3081 * m4.c: Call setup_stackovf_trap().
3082 * tests/stackovf_test.sh: New file.
3084 Wed Apr 13 14:10:30 1994 Francois Pinard (pinard@icule)
3086 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
3088 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
3090 Sun Jan 30 14:24:19 1994 (pinard at icule)
3092 * m4.h: Remove definition of volatile, not used anymore.
3093 Reported by Jim Meyering and Joseph E. Sacco.
3095 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
3096 of `if ... else /* nothing */' for if macros.
3097 Reported by Jim Meyering.
3099 * builtin.c (m4_regexp): Reorganize the code for avoiding a
3100 warning from gcc about `repl' possibly used before defined.
3101 Reported by Jim Meyering.
3103 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
3104 Reported by Jim Meyering.
3106 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
3108 * m4.h: Move the conditional definition of volatile after the
3109 inclusion of system files, because they may define it first.
3111 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
3113 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
3114 get around a problem with Alpha make seeing a syntax error, there.
3115 Reported by Vern Paxson.
3117 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
3119 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
3120 Reported by Richard Stallman.
3122 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)
3124 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
3125 instead of AC_HAVE_FUNCS.
3126 Reported by Noah Friedman.
3128 Wed Dec 1 09:37:53 1993 Francois Pinard (pinard@icule)
3130 * m4.c: Initialize show_help and show_version to zero.
3132 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
3133 Use them in exit() and usage() calls.
3135 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
3137 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
3138 syserr() macro. Delete errref, add reference_error and M4ERROR.
3139 * m4.c: Replace errref, which was returning an input reference
3140 string, with reference_error, which prints it on standard error.
3141 * builtin.c, output.c: Use errno as second parameter to error,
3142 instead of using syserr() with %s.
3143 * *.c: Use M4ERROR instead of error: no more errref() with %s.
3144 Doing so, the program name appears after the input reference
3145 instead of before, which eases M-x next-error processing.
3147 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
3149 * checks/get-them: Escape braces with backslashes in patterns,
3150 because HPUX-9.01 awk needs this.
3151 Reported by Jim Meyering.
3153 Mon Nov 22 10:55:52 1993 Francois Pinard (pinard@icule)
3155 * builtin.c: Declare "FILE *popen ();".
3157 * m4.h: Remove MESSAGE{,1,2}, WARNING1, FATAL{,1}, INTERNAL_ERROR
3158 macros, replace error_message_prefix() declaration by errref()'s.
3159 Declare xrealloc, for use in errref().
3160 * m4.c: Delete error_message_prefix() function, add errref().
3161 * *.c: Use error() systematically in place of all error macros,
3162 now that error() flushes stdout first. Make needed adjustments.
3164 * m4.h: Remove const in sys_errlist[] declaration, it creates
3165 conflicts on SGI and Alpha.

3184 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
3186 * input.c (input_init): Initialize quote and comment strings
3187 explicitely instead of calling set_quotes and set_comment: by

3191 expected is on the left and the obtained on the right.
3193 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR

3243 Reported by Joel Sherrill.
3245 * builtin.c (prefix_all_builtins): Instead of the table size, use
3246 the null entry at end for stopping the loop. It was overwritten.
3247 Reported by Andreas Schwab and Jim Meyering.
3249 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
3250 Reported by Kaveh R. Ghazi.

3272 Reported by Tom McConnell.
3274 Mon Nov 8 12:45:34 1993 Francois Pinard (pinard@icule)
3278 * configure.in: Do not copy check files in the build hierarchy.
3279 * checks/check-them: Identify the m4 version being checked. For
3280 finding m4, look in $PATH instead of in the parent directory.
3281 * Makefile.in (check): Prepend `pwd` to $PATH before checking.
3282 * checks/Makefile.in (.all-stamp): Always create check files in
3283 the source hierarchy, not anymore in the build hierarchy.

3449 Fri Jan 15 16:07:00 1993 Francois Pinard (pinard@icule)
3451 * lib/vfprintf.c: Stolen from Oleo distribution and adapted. The

3478 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.
3480 * examples/divert.m4: Deleted, this bug has been corrected.
3482 * Makefile.in (texclean, mostlyclean): New goals.
3484 * Makefile.in (clean): Remove clutter from ansi2knr.
3485 Reported by Pierre Gaumond.

3501 Sat Dec 19 08:21:34 1992 Francois Pinard (pinard at icule)
3504 This is still a beta release for the future GNU m4 version 1.1.
3506 * lib/alloca.c: New, from elsewhere.
3507 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
3509 * m4.h: Do not define index/rindex if already defined. If
3510 FALSE/TRUE are already defined, do not redefine them, but merely
3511 define boolean typedef to int.
3513 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
3514 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
3515 because some C compilers do not like connectives with #ifdef.
3516 * m4.h: Define `volatile' only if __GNUC__, instead of once for
3517 __GNUC__ and once for __STDC__.
3518 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
3520 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
3521 Makefile dependencies. Without it, make keeps destroying and
3522 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
3524 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
3525 to diversion/DIVERSION, this was a spelling error.
3527 * m4.c: Declare version[], remove #include "version.h".
3528 * version.h: Deleted.
3529 * Makefile.in: Remove references to version.h.
3531 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
3532 production, by using a simpler and more robust algorithm. This
3533 solves the problem of synclines sometimes written in the middle of
3534 an output line. Delete sync_line() and output_lines variable.
3535 * m4.h: Remove sync_line prototype and output_lines declaration.
3536 * input.c (next_char), output.c (shipout_text): Remove references
3538 * input.c (push_file, pop_file): Merely put the value -1 in
3539 output_current_line instead of calling sync_line, for delaying a
3540 single `#line NUM FILE' before next output line. Do not test
3541 for sync_output, because this is unnecessary clutter.
3542 * output.c (make_divertion, insert_divertion): Idem.
3543 * input.c: Rename must_advance_line to start_of_input_line, for
3546 * debug.c (trace_header): Select a new debug line format, which
3547 better complies with GNU standards for formatting error messages.
3548 With option `-dfl', M-x next-error might be used on the output.
3549 * m4.c (vmesg): Adjust format of error output to GNU standards.
3550 * m4.texinfo: Adjust examples for `make check' to work.
3552 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
3553 case for enum debug_info constants, which were all lower case.
3555 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
3557 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
3558 collected patches. I tried a few times using newer regex.[ch], it
3559 mysteriously stopped aborting with this one. Insecure feeling...
3560 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
3562 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
3564 * m4.c: Change `--no-warnings' to `--silent'.
3565 Reported by David MacKenzie.
3567 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
3568 leave it off for now. See comment in m4.c for justification.
3569 Reported by David MacKenzie.
3571 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
3572 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
3574 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
3576 * Makefile.in: Ensure recursive cleaning is done before local
3577 cleaning for all clean goals.
3579 * builtin.c (ntoa): Ensure the value is always interpreted as a
3580 signed quantity, whatever the radix is.
3582 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
3584 * builtin.c, format.c, input.c: Split long lines.
3585 * m4.c: Use typedef macro_definition instead of struct
3587 * symtab.c: Use typedef symbol instead of struct symbol.
3589 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
3591 * *.[ch]: Remove all trailing whitespace, in code and comments.
3593 * configure.in: Find some awk.
3594 * Makefile.in: Add $(AWK) to MDEFINES.
3595 * checks/Makefile.in: Transmit $(AWK) to get_them.
3596 * checks/get_them: Use $AWK instead of gawk. Add a close in the
3597 awk script when switching files, because without this, mawk runs
3598 out of file descriptors.
3600 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
3602 * Makefile.in (realclean): Delete m4.info*.
3603 Reported by Jim Meyering.
3605 * Makefile.in: Adjust and link with checks/Makefile.
3606 * checks/Makefile.in: New.
3607 * configure.in: Output checks/Makefile.
3609 * checks/get_them: Have the dnl header of each test more
3610 recognizable by next-error, also use a better message.
3612 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
3614 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
3615 And use that only if __GNUC__ since we're using it's GCC-specific
3616 semantics that tell the compiler the associated function doesn't
3619 * builtin.c (substitute): Don't use character as an array index.
3620 (dumpdef_cmp): Make formal arguments `const void *' to avoid
3621 warnings with gcc -W -Wall on systems with qsort prototype.
3622 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
3625 * eval.c (most functions): Add parentheses to assignments used
3626 as truth values go avoid warnings from gcc -Wall.
3628 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
3629 any functions that don't need external scope.
3631 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
3632 (many functions and arrays): Declare `const'.
3634 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
3636 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
3637 removing the declaration from m4.h. Also rename false to FALSE
3640 * lib/Makefile.in (Makefile): New goal.
3642 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
3643 so heavily loaded. It gets more easily overridable, calling make.
3644 Reported by Jim Meyering.
3646 * Makefile.in (dist): Get .fname from the current directory name,
3647 instead of from version.h. I need updating many files manually,
3648 when the version changes, version.h is just one of them.
3650 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
3652 * m4.h: Remove the tag `boolean' on the enum introducing typedef
3653 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
3654 Reported by Tom McConnell.
3656 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
3658 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
3659 39.cleardiv, which were describing missing or spurious newlines.
3660 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
3661 do not depend on machine word size, `/bin/false' implementation,
3662 or `wc' output format. `make check' is more dependable, now.
3664 * checks/check_them: Summarize the failed tests by listing their
3665 name, at end. If none, issue `All checks successful'. Output
3666 `Checking' instead of `Input file:'.
3668 * checks/get_them, checks/check_them: Reindented.
3670 * Makefile.in (dist): chmod a+r before making the tar file.
3672 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
3674 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
3676 * input.c (next_token): Reinitialize token_buttom just after using
3677 it as a watermark with obstack_free. Or else, a future token, big
3678 enough for triggering reallocation of the obstack chunk, could
3679 void the initialized value of token_buttom, later causing panic in
3680 obstack_free. Rename token_buttom to token_bottom everywhere.
