2156 empty file rather than to a nonexistent file. This closes a common
2158 * src/builtin.c (m4_maketemp): Implement the above, by using
2159 mkstemp rather than mktemp. (trivial change)
2161 2000-01-09 Akim Demaille <demaille@inf.enst.fr>

2184 * src/macro.c (collect_arguments): Cast obstack arguments to
2185 (voidstar), so avoiding compiler warnings.
2186 Reported by Joseph E. Sacco.

2207 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
2208 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler

2226 ANSI2KNR, depending on the fact the compiler is ANSI or not.
2227 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
2228 Remove the sed filter after ansi2knr for debug.c. Use $O instead
2229 of $U, put underline in extensions rather than in basenames. Use
2230 implicit rules, now that regularity makes this possible.
2231 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
2232 of ansi2knr whenever it is needed.
2233 * configure.in: Adjusted for correct STACKOVF substitution.
2234 * src/debug.c (trace_format): When not __STDC__, use (...) as a
2235 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.

2251 Reported by Jim Kingdon.
2253 * {,/*}Makefile.in: Use && after all cd, in case they fail.
2255 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.

2332 Reported by Kaveh R. Ghazi.
2334 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
2335 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
2338 * configure.in: Use date instead of touch for stamp-h.
2339 * Makefile.in (stamp-h.in): Idem.
2341 * Makefile.in (distclean, realclean): Force serial execution of

2394 calling a function by that name. Declare the variable.
2395 * src/m4.h: Adjust declaration for prefix_all_buitins.
2396 * src/builtin.c (builtin_init): Merge in functionality from
2397 previous prefix_all_buitins function, while making entries in the
2398 symbol table, but not modifying the builtin description itself.
2400 * src/freeze.c (reload_frozen_state): Add a useless `break;',
2401 because *many* compilers do not accept an empty `default:'.
2402 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
2403 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
2405 * configure.in: Use AC_TYPE_SIGNAL.

2427 * configure.in: Configure new Makefiles.
2429 * m4.h: Declare STRING typedef. Use it for comment and quote
2430 strings, adjusting all references. (This is the rudiments of a

2432 * output.c (shipout_text): Accept a length parameter, and use it.
2433 All callers adjusted.
2435 Mon Aug 29 12:27:19 1994 Francois Pinard (pinard@icule)

2463 frozen. Do not call builtin_init when reloading frozen state.
2465 Speed up diversion processing:

2487 * freeze.c: New file.
2488 * Makefile.in: Compile it, distribute it.
2489 * m4.c: Recognize, document and process --freeze-state (-F) and
2490 --reload-state (-R) options. Pass a true flag to builtin_init
2491 only if no reloading some state.

2557 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
2559 * configure.in: Check for sigaction and sigvec. Add a new delayed
2560 check for RLIMIT_STACK, combine in the checking for getrlimit.
2561 All those things are not universally available.
2562 * stackovf.c: Split setting up the trap handler and catching
2563 signals, for better taking care of various configure outcomes.

2579 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
2580 error message, for when no code possibility exists. Even if this
2581 line is completely #ifdef'ed out, it brings a syntax error.
2582 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
2584 * Makefile.in (install): Have install depend on all too, for lib
2585 to be remade as needed.
2587 * examples/stackovf.sh: Try ksh, bsh and bash for shells
2588 providing ulimit, instead of using only ksh.
2589 Reported by Jim Avera and Joseph E. Sacco.
2591 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
2593 * Makefile.in (check): Have it depend on all instead of m4. In
2594 this way, a change in lib will be detected and processed.
2596 * builtin.c (numeric_arg): Use strtol and verify the conversion,
2597 instead of using sscanf which stops as soon as there is a
2598 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
2599 and divert(1xyzzy) were all accepted without any warning or error
2601 * m4.h: Declare strtol as long if not including stdlib.h.
2602 * configure.in: Check for limits.h, and replace strtol if missing.
2603 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
2604 * lib/strtol.c: New file, from elsewhere.

2616 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
2618 * stackovf.c: Isolated OS-dependent sections; Improved portability,
2619 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
2620 handlers), and a default error message if the fault address is not
2621 available (when neither siginfo.h nor BSD sigcontext are supported).
2622 * configure.in: Changes for stackovf.h: Check for sigcontext,
2623 sigaction, sigstack, and define rlim_t as int if necessary.
2624 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
2625 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.

2635 Reported by Ian Taylor.
2637 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
2639 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
2640 because siginfo.h is unrelated to standard headers, and siginfo.h
2641 is already checked for.
2642 Reported by Joseph E. Sacco.
2644 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
2646 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
2649 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
2651 * builtin.c (substitute): Use \& to represent this part of the
2652 string which was matched by the whole regexp, instead of
2653 representing the whole string. Any usage of \0 issues a warning
2654 and acts like \&, it will disappear in some subsequent release.
2656 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
2658 * m4.c: Complete prototype for forwarded declaration of usage.
2660 * input.c (init_macro_token): Correct own reference in error
2661 message. Previous name get_macro_func was referred to instead.
2662 (next_char): Correct own reference in error message. Previous
2663 name advance_input was referred to instead.
2665 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
2666 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
2667 and_term, not_term, logical_not_term, cmp_term, shift_term,
2668 add_term, mult_term, exp_term, unary_term, simple_term): Add
2669 prototype to forwarded declarations. Declare parameter v1 as
2670 eval_t * instead of int *. Same for local variable v2 in dyadic
2671 functions. Same for result in exp_term.
2672 * builtin.c (m4_eval): Declare value as eval_t instead of int.
2673 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
2674 unsigned_eval_t instead of unsigned int. Change casts accordingly.
2675 (shipout_int): Cast first argument of ntoa to eval_t.
2676 Reported by Thorsten Ohl.
2678 * macro.c: Complete the prototypes of forwarded expand_macro and
2680 Reported by Thorsten Ohl.
2682 * m4.h: Define voidstar as void * or char * depending on __STDC__.
2683 The Ultrix 3.1 compiler cannot do much with void pointers.
2685 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
2686 * m4.c (xfree): Replace void * by voidstar.
2687 Reported by Tom McConnell.
2689 * ansi2knr.1: New, from elsewhere.
2690 * Makefile.in (DISTFILES): Distribute ansi2knr.1
2692 * Makefile.in (stamp-h.in): Avoid running ./config.status if
2693 stamp-h does not exist yet. This avoids running it a second time
2694 just after the initial ./configure.
2695 Reported by David MacKenzie and Tom McConnell.
2697 * m4.h: Replace the enum debug_info declaration with a series of
2698 #define's. The Ultrix 3.1 compiler would otherwise need casting
2699 (int) to most references, when used in expressions.
2700 Reported by Tom McConnell.
2702 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
2704 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
2705 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
2706 calls the compiler. Previously, FP_PROTOTYPES was only calling
2707 the preprocessor; by not being subject to CFLAGS, this was
2708 discouraging those flags asking for ANSI compilation.
2709 * acconfig.h: Document HAVE_PROTOTYPES.
2710 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
2711 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
2712 Reported by Eric Backus.
2714 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
2715 from the environment. Default CFLAGS to -g if not set.
2716 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
2717 * lib/Makefile.in: Have CFLAGS substituted from configure.
2718 Reported by Eric Backus and Tom McConnell.
2720 * configure.in: m4_undefine changeword before using AC_ENABLE.
2722 * m4.h: Declare prototypes for error (for ANSI compilers only),
2723 prefix_all_builtins and reference_error.
2724 Reported by Tom McConnell.
2726 * input.c (set_word_regexp): Do not try to initialize the array
2727 test from a string, this does not work with non-ANSI compilers.
2728 Reported by Eric Backus.
2730 * Makefile.in (dist): Clean examples/ before saving it.
2731 (distclean-local): Also remove stamp-h.
2732 Reported by Eric Backus.
2734 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
2736 Reported by Tom McConnell.
2738 * checks/Makefile.in (clean): Depends on mostlyclean.
2739 (mostlyclean): New goal.
2741 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
2743 * Makefile.in (DISTFILES): Distribute install.sh.
2744 * install.sh: New file, copied from elsewhere.
2745 Reported by Assar Westerlund and Kaveh R. Ghazi.
2747 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
2749 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
2750 * acconfig.h: Explain ENABLE_CHANGEWORD.
2752 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
2753 from code provided by Pete Chown]
2754 * m4.h: Add original_text field to u_t variant of union u.
2755 Declare TOKEN_DATA_FUNC macro.
2756 * builtin.c: Declare changeword.
2757 (m4_changeword): New function.
2758 * input.c: Include "regex.h", define variables with word regexps.
2759 (input_init): Initialize the word regexp.
2760 (set_word_regexp): New.
2761 (next_token): Declare local variables, use the previous code if
2762 default_word_regexp is true. Else, match using a new code. Save
2764 * macro.c (expand_token): Ship out original text if not a macro
2766 Reported by Krste Asanovic and Pete Chown.
2768 [These modifs all depend upon ENABLE_CHANGEWORD]
2769 * m4.h: Declare external user_word_regexp.
2770 * m4.c: Declare user_word_regexp, and initialize it from
2771 --word-regexp or -W, or NULL if not specified.
2772 * input.c: Use user_word_regexp if specified, instead of
2773 DEFAULT_WORD_REGEXP.
2775 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
2778 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
2779 * checks/Makefile.in: Empty the suffix list.
2780 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
2782 * m4.c: Declare nesting_limit and initialize it to 250.
2783 Implement -LNUMBER or --nesting-limit=NUMBER to change its
2785 * m4.h: Declare nesting_limit as external.
2786 * macro.c (expand_macro): Stop execution whenever nesting limit
2788 Reported by Bengt Mertensson.
2790 * eval.c (evaluate): Diagnose excess characters in eval input.
2791 Things like `eval(08)' used to return 0 with no diagnostic.
2793 * m4.h: Capitalize first letter of all macro arguments in
2796 * m4.c: Declare warning_status, initialize it to 0. Add new
2797 option -E, or --fatal-warnings, which sets warning_status to
2798 EXIT_FAILURE instead.
2799 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
2800 EXIT_FAILURE if not otherwise done by header files.
2801 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
2802 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
2803 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
2804 argument of all M4ERROR calls.
2805 Reported by Noah Friedman.
2807 * examples/incl-test.m4: Renamed from incl_test.m4.
2808 * examples/include.m4: Include incl-test.m4 instead of
2810 * examples/multiquotes.m4: Renamed from multi-quotes.m.
2812 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
2814 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
2815 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
2816 also tested it on a Sun Sparc workstation running SunOS 4.x.
2818 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
2819 49.format check, abusing a `union values' argument with sprintf
2820 without selecting the proper field. Now, save the formatting type
2821 first, delaying the fetch of the corresponding argument.
2822 Reported by Joseph E. Sacco and Tom Quinn.
2824 * format.c (format): Remove const from char *fmt declaration when
2825 not HAVE_EFGCVT, because a NUL may be forced into it.
2827 * m4.h: Declare atof() when not STDC_HEADERS.
2828 Reported by Joseph E. Sacco.
2830 * Regenerate configure using Autoconf 1.11, this corrects a
2831 problem about an incorrect cpp seting on NeXT 3.1.
2832 Reported by Alexander Lehmann.
2834 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
2836 * m4.h (_): Change argument from `x' to `Args'.
2838 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
2840 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
2841 bringing more evil than good on a few systems.
2842 Reported by Greg A. Woods.
2844 Fri Apr 22 15:59:35 1994 Francois Pinard (pinard@icule)
2846 * m4.h: Rename Args() to _().

2854 substitute ${U}stackovf.o for STACKOVF.
2855 * acconfig.h: Declare USE_STACKOVF.
2856 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
2857 * m4.h: Declare setup_stackovf_trap().
2858 * m4.c: Call setup_stackovf_trap().
2859 * tests/stackovf_test.sh: New file.

2863 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
2865 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
2867 Sun Jan 30 14:24:19 1994 (pinard at icule)
2869 * m4.h: Remove definition of volatile, not used anymore.
2870 Reported by Jim Meyering and Joseph E. Sacco.
2872 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
2873 of `if ... else /* nothing */' for if macros.
2874 Reported by Jim Meyering.
2876 * builtin.c (m4_regexp): Reorganize the code for avoiding a
2877 warning from gcc about `repl' possibly used before defined.
2878 Reported by Jim Meyering.
2880 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
2881 Reported by Jim Meyering.
2883 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
2885 * m4.h: Move the conditional definition of volatile after the
2886 inclusion of system files, because they may define it first.
2888 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
2890 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
2891 get around a problem with Alpha make seeing a syntax error, there.
2892 Reported by Vern Paxson.
2894 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
2896 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
2897 Reported by Richard Stallman.
2899 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)
2901 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
2902 instead of AC_HAVE_FUNCS.
2903 Reported by Noah Friedman.
2905 Wed Dec 1 09:37:53 1993 Francois Pinard (pinard@icule)
2907 * m4.c: Initialize show_help and show_version to zero.
2909 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
2910 Use them in exit() and usage() calls.
2912 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
2914 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
2915 syserr() macro. Delete errref, add reference_error and M4ERROR.
2916 * m4.c: Replace errref, which was returning an input reference
2917 string, with reference_error, which prints it on standard error.
2918 * builtin.c, output.c: Use errno as second parameter to error,
2919 instead of using syserr() with %s.
2920 * *.c: Use M4ERROR instead of error: no more errref() with %s.
2921 Doing so, the program name appears after the input reference
2922 instead of before, which eases M-x next-error processing.
2924 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
2926 * checks/get-them: Escape braces with backslashes in patterns,
2927 because HPUX-9.01 awk needs this.

2936 Declare xrealloc, for use in errref().
2937 * m4.c: Delete error_message_prefix() function, add errref().
2938 * *.c: Use error() systematically in place of all error macros,
2939 now that error() flushes stdout first. Make needed adjustments.
2941 * m4.h: Remove const in sys_errlist[] declaration, it creates
2942 conflicts on SGI and Alpha.
2943 Reported by Kaveh R. Ghazi.
2945 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)

2961 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
2963 * input.c (input_init): Initialize quote and comment strings
2964 explicitely instead of calling set_quotes and set_comment: by
2965 doing so, we ensure we do not free uninitialized variables.
2967 * checks/check-them: Reverse arguments to both diff, so the
2968 expected is on the left and the obtained on the right.
2970 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
2971 macros. Delete declarations for m4error, warning, fatal and
2972 internal_error, add declaration for error_message_prefix.
2973 * m4.c: Delete m4error, warning, fatal and internal_error
2974 routines, add error_message_prefix routine.
2975 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
2976 warning with WARNING*, fatal with FATAL* and internal_error with
2978 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
2979 this is not needed anymore.
2981 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
2982 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
2983 and debug_message, add declaration for debug_message_prefix.
2984 * debug.c: Remove static specifier for FILE *debug declaration.
2985 Delete debug_print and debug_message routines, add
2986 debug_message_prefix routine.
2987 * builtin.c, debug.c: Replace debug_print routine calls with
2988 DEBUG_PRINT* macro calls.

2994 (trace_format): Use stdarg instead of varargs if __STDC__.
2996 * configure.in: Remove checks for vfprintf and _doprnt. These
2997 implementations use varargs tricks which are not portable enough.
2998 * lib/vfprintf.c: Deleted.
2999 * lib/_doprnt.c: Deleted.
3000 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.
3001 Reported by Joel Sherrill.

3020 Reported by Joel Sherrill.
3022 * builtin.c (prefix_all_builtins): Instead of the table size, use
3023 the null entry at end for stopping the loop. It was overwritten.
3024 Reported by Andreas Schwab and Jim Meyering.
3026 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
3027 Reported by Kaveh R. Ghazi.

3049 Reported by Tom McConnell.
3051 Mon Nov 8 12:45:34 1993 Francois Pinard (pinard@icule)
3055 * configure.in: Do not copy check files in the build hierarchy.

3226 Fri Jan 15 16:07:00 1993 Francois Pinard (pinard@icule)
3228 * lib/vfprintf.c: Stolen from Oleo distribution and adapted. The

3244 * Makefile.in: Add DEFS to MDEFINES.
3245 * lib/Makefile.in (.c.o): Remove $(CPPFLAGS).
3246 (libm4.a): Remove the library before creating it.
3247 (distclean): Remove tags and TAGS too.
3249 Wed Dec 23 12:46:55 1992 Francois Pinard (pinard at icule)
3251 * Makefile.in (dvi, m4.dvi): New goals.

3254 macro.c, output.c, path.c, symtab.c: Change Copyright from
3255 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.
3257 * examples/divert.m4: Deleted, this bug has been corrected.
3259 * Makefile.in (texclean, mostlyclean): New goals.
3261 * Makefile.in (clean): Remove clutter from ansi2knr.
3262 Reported by Pierre Gaumond.
3263 Reported by Greg A. Woods.
3265 Sun Dec 20 10:40:20 1992 Francois Pinard (pinard at icule)
3267 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user

3278 Sat Dec 19 08:21:34 1992 Francois Pinard (pinard at icule)
3281 This is still a beta release for the future GNU m4 version 1.1.
3283 * lib/alloca.c: New, from elsewhere.
3284 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
3286 * m4.h: Do not define index/rindex if already defined. If
3287 FALSE/TRUE are already defined, do not redefine them, but merely
3288 define boolean typedef to int.
3290 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
3291 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
3292 because some C compilers do not like connectives with #ifdef.
3293 * m4.h: Define `volatile' only if __GNUC__, instead of once for
3294 __GNUC__ and once for __STDC__.
3295 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
3297 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
3298 Makefile dependencies. Without it, make keeps destroying and
3299 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
3301 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
3302 to diversion/DIVERSION, this was a spelling error.
3304 * m4.c: Declare version[], remove #include "version.h".
3305 * version.h: Deleted.
3306 * Makefile.in: Remove references to version.h.
3308 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
3309 production, by using a simpler and more robust algorithm. This
3310 solves the problem of synclines sometimes written in the middle of
3311 an output line. Delete sync_line() and output_lines variable.
3312 * m4.h: Remove sync_line prototype and output_lines declaration.
3313 * input.c (next_char), output.c (shipout_text): Remove references
3315 * input.c (push_file, pop_file): Merely put the value -1 in
3316 output_current_line instead of calling sync_line, for delaying a
3317 single `#line NUM FILE' before next output line. Do not test
3318 for sync_output, because this is unnecessary clutter.
3319 * output.c (make_divertion, insert_divertion): Idem.
3320 * input.c: Rename must_advance_line to start_of_input_line, for
3323 * debug.c (trace_header): Select a new debug line format, which
3324 better complies with GNU standards for formatting error messages.
3325 With option `-dfl', M-x next-error might be used on the output.
3326 * m4.c (vmesg): Adjust format of error output to GNU standards.
3327 * m4.texinfo: Adjust examples for `make check' to work.
3329 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
3330 case for enum debug_info constants, which were all lower case.
3332 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
3334 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
3335 collected patches. I tried a few times using newer regex.[ch], it
3336 mysteriously stopped aborting with this one. Insecure feeling...
3337 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
3339 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
3341 * m4.c: Change `--no-warnings' to `--silent'.
3342 Reported by David MacKenzie.
3344 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
3345 leave it off for now. See comment in m4.c for justification.
3346 Reported by David MacKenzie.
3348 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
3349 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
3351 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
3353 * Makefile.in: Ensure recursive cleaning is done before local
3354 cleaning for all clean goals.
3356 * builtin.c (ntoa): Ensure the value is always interpreted as a
3357 signed quantity, whatever the radix is.
3359 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
3361 * builtin.c, format.c, input.c: Split long lines.
3362 * m4.c: Use typedef macro_definition instead of struct
3364 * symtab.c: Use typedef symbol instead of struct symbol.
3366 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
3368 * *.[ch]: Remove all trailing whitespace, in code and comments.
3370 * configure.in: Find some awk.
3371 * Makefile.in: Add $(AWK) to MDEFINES.
3372 * checks/Makefile.in: Transmit $(AWK) to get_them.
3373 * checks/get_them: Use $AWK instead of gawk. Add a close in the
3374 awk script when switching files, because without this, mawk runs
3375 out of file descriptors.
3377 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
3379 * Makefile.in (realclean): Delete m4.info*.
3380 Reported by Jim Meyering.
3382 * Makefile.in: Adjust and link with checks/Makefile.
3383 * checks/Makefile.in: New.
3384 * configure.in: Output checks/Makefile.
3386 * checks/get_them: Have the dnl header of each test more
3387 recognizable by next-error, also use a better message.
3389 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
3391 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
3392 And use that only if __GNUC__ since we're using it's GCC-specific
3393 semantics that tell the compiler the associated function doesn't
3396 * builtin.c (substitute): Don't use character as an array index.
3397 (dumpdef_cmp): Make formal arguments `const void *' to avoid
3398 warnings with gcc -W -Wall on systems with qsort prototype.
3399 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
3402 * eval.c (most functions): Add parentheses to assignments used
3403 as truth values go avoid warnings from gcc -Wall.
3405 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
3406 any functions that don't need external scope.
3408 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
3409 (many functions and arrays): Declare `const'.
3411 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
3413 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
3414 removing the declaration from m4.h. Also rename false to FALSE
3417 * lib/Makefile.in (Makefile): New goal.
3419 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
3420 so heavily loaded. It gets more easily overridable, calling make.
3421 Reported by Jim Meyering.
3423 * Makefile.in (dist): Get .fname from the current directory name,
3424 instead of from version.h. I need updating many files manually,
3425 when the version changes, version.h is just one of them.
3427 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
3429 * m4.h: Remove the tag `boolean' on the enum introducing typedef
3430 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
3431 Reported by Tom McConnell.
3433 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
3435 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
3436 39.cleardiv, which were describing missing or spurious newlines.
3437 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
3438 do not depend on machine word size, `/bin/false' implementation,
3439 or `wc' output format. `make check' is more dependable, now.
3441 * checks/check_them: Summarize the failed tests by listing their
3442 name, at end. If none, issue `All checks successful'. Output
3443 `Checking' instead of `Input file:'.
3445 * checks/get_them, checks/check_them: Reindented.
3447 * Makefile.in (dist): chmod a+r before making the tar file.
3449 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
3451 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
3453 * input.c (next_token): Reinitialize token_buttom just after using
3454 it as a watermark with obstack_free. Or else, a future token, big
3455 enough for triggering reallocation of the obstack chunk, could
3456 void the initialized value of token_buttom, later causing panic in
3457 obstack_free. Rename token_buttom to token_bottom everywhere.
3459 * m4.h: Before declaring errno, first include <errno.h> and
3460 ensure that it does not define errno.
3461 Reported by Richard Stallman.
3463 Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule)
3465 * builtin.c: Define and use DECLARE macro for builtins.
3467 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
3468 argument, this is a common idiom for introducing long comments.
3470 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
3471 arguments. The last argument was silently ignored.
3473 * m4.c (cmd_error): Add a missing semicolon before va_end().
3475 Tue Nov 10 08:57:05 1992 Francois Pinard (pinard at icule)
3477 * Makefile.in: Now handle protoized sources. Define and use U.
3478 Compile and use ansi2knr with old compilers. Update DISTFILES.
3479 Add `aclocal.m4' to `configure' dependencies.
3480 * ansi2knr.c: New, from Ghostscript distribution.
3481 * configure.in: Define U through FP_PROTOTYPES for old compilers.
3482 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
3483 * aclocal.m4: New, provide FP_PROTOTYPES.
3484 * m4.h: Conditionnaly protoized through Args, save for varags.
3485 * builtin.c: Protoized. Then:
3486 Include <sys/types.h> if size_t is not defined, before "regex.h".

3488 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
3489 (m4_regexp): Add const to `msg' declaration.
3490 (m4_patsubst): Add const to `msg' declaration.
3491 * debug.c: Protoized, save for varargs.
3492 * eval.c: Protoized.
3493 * format.c: Protoized.
3494 * input.c: Protoized.
3495 * m4.c: Protoized, save for varargs. Then:
3496 (xfree): Accept void * instead of char *.
3497 (xmalloc): Return void * instead of char *.
3498 (xrealloc): Accept and return void * instead of char *.
3499 * macro.c: Protoized.
3500 * output.c: Protoized.
3501 * path.c: Protoized. Then cast some (char *) over xmalloc's.
3502 * symtab.c: Protoized.
3504 Fri Nov 6 02:05:21 1992 Francois Pinard (pinard at icule)
3506 * m4.texinfo: Remove directory from diagnostics in 30.include,
3507 51.eval, 56.errprint and 57.m4exit tests.
3509 * m4.h: Remove declarations for int or void system functions, they
3510 cause more conflicting trouble than they make good.
3512 * configure.in: Avoid configuration header file. Add some tests.
3513 * m4.h: Remove #include "config.h".
3514 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
3515 Then, rewritten for better compliance with GNU standards.
3517 Thu Nov 5 12:37:13 1992 Francois Pinard (pinard at icule)
3519 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
3520 because of a misplaced #endif.
3522 * Many *.[hc] files: Correct intra-line spacing here and there,
3523 according to GNU indent 1.6 advice.

3536 * version.h: De-automatize, force value in.
3538 * m4.c: Changes in order to use a newer getopt.h.
3539 Reported by David MacKenzie.
3541 * checks/: New name for examples/.
3542 * checks/get_them: New location for etc/get_examples.

3551 * Makefile.in (check): Add m4 as dependency.
3553 * m4.c: Accept --no-warnings instead of --no_warnings, and
3554 --no-gnu-extensions instead of --no_gnu_extensions. Make the
3555 usage message more informative.

3572 Reported by Richard Stallman.
3574 * config/hmake-unicos, config/s-unicos.h: New files.
3575 Reported by Hal Peterson.
3577 * eval.c (exp_term): Have N^0 return 1.
3578 Reported by Michael Fetterman.
