1723 xvasprintf.

1780 time with changequote. Document a traditional incompatibility
1781 with partial input spanning file boundaries.

2349 2005-02-03 Gary V. Vaughan <gary@gnu.org>

2516 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
2517 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
2518 defines __STDC__ to 0, for indicating it is *not* ANSI!
2519 Reported by Kaveh R. Ghazi.
2521 * configure.in: Added obsolescent tests for AIX and Minix.
2523 * doc/Makefile.in (mostlyclean): Remove texclean in dependencies,

2534 * aclocal.m4 (fp_C_PROTOTYPES): Substitute empty or ansi2knr for
2535 ANSI2KNR, depending on the fact the compiler is ANSI or not.
2536 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
2537 Remove the sed filter after ansi2knr for debug.c. Use $O instead
2538 of $U, put underline in extensions rather than in basenames. Use
2539 implicit rules, now that regularity makes this possible.
2540 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
2541 of ansi2knr whenever it is needed.
2542 * configure.in: Adjusted for correct STACKOVF substitution.
2543 * src/debug.c (trace_format): When not __STDC__, use (...) as a
2544 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.
2545 Reported by David MacKenzie.
2547 * Makefile.in: Remove binprefix. Use transform_name instead.
2548 Reported by David MacKenzie.
2550 * doc/Makefile.in: Create version.texi, use it, clean it.

2553 Fri Oct 28 20:33:55 1994 Francois Pinard (pinard@icule)
2555 * Makefile.in (all, install, uninstall): Depend on Makefile.
2557 * Makefile.in: For actions invoking $(MAKE) from within compound
2558 sh statements, exit non-zero if the sub-make fails. Otherwise,

2560 Reported by Jim Kingdon.
2562 * {,/*}Makefile.in: Use && after all cd, in case they fail.
2564 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.

2596 (setup_stackovf_trap): Use RETSIGTYPE instead of void while
2597 casting sigsegv_handler.
2598 Reported by Robert Bernstein.
2600 * src/m4.c (main): Initialize program_name to argv[0] without

2617 unreacheable and useless.
2619 * doc/Makefile.in (texclean): Deleted, merged in mostlyclean.
2621 * lib/Makefile.in (DISTFILES): Distribute TAGS.
2622 (distclean): Do not remove TAGS.
2623 (realclean): Remove it.
2624 * Makefile.in: Make TAGS in lib also, not just in src.
2625 Reported by Karl Berry.
2627 * Makefile.in (distclean, realclean): Instead of recursively
2628 calling $(MAKE) for the -local part, allow parallel execution of
2629 -recursive and -local, only delay the removal of config.status,
2630 which is repeated in both goals.
2631 \f
2632 Tue Sep 13 19:21:05 1994 Francois Pinard (pinard@icule)
2634 Release 1.3.
2635 * Makefile.in: Group all *clean-recursive goals in one, using sed
2636 to remove `-recursive' while calling make recursively. Also, use
2637 a subshell for each recursive $(MAKE).
2638 Reported by Jim Meyering.
2640 * src/m4.h (memcpy): Define with bcopy for BSD systems.
2641 Reported by Kaveh R. Ghazi.
2643 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
2644 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
2645 specify it.
2647 * configure.in: Use date instead of touch for stamp-h.
2648 * Makefile.in (stamp-h.in): Idem.
2650 * Makefile.in (distclean, realclean): Force serial execution of

2664 Thu Sep 8 15:07:27 1994 Francois Pinard (pinard@icule)
2666 * Makefile.in (MDEFINES): Remove INSTALL substitutions, for
2667 ./install.sh will not be correctly referred to in sub-Makefiles.
2668 Reported by John David Anglin.

2671 Reported by Eric Backus.
2673 * Makefile.in, checks/Makefile.in, doc/Makefile.in,
2674 examples/Makefile.in, lib/Makefile.in, src/Makefile.in: Limit

2678 Reported by Jim Meyering.
2680 Tue Sep 6 12:07:33 1994 Francois Pinard (pinard@icule)
2682 * configure.in: Correct stack overflow detection logic, taking
2683 care of systems having only incomplete implementations (like for
2684 Pyramid 9820 OSx 5.0d).
2685 Reported by Kaveh R. Ghazi.
2687 * src/Makefile.in (TAGS): Remote -t from etags call.
2689 Fri Sep 2 10:37:10 1994 Francois Pinard (pinard@icule)

2699 Reported by Jim Meyering.
2701 Solidify frozen files with respect to -P:
2702 * src/m4.c: Have -P set prefix_all_buitins variable instead of
2703 calling a function by that name. Declare the variable.
2704 * src/m4.h: Adjust declaration for prefix_all_buitins.
2705 * src/builtin.c (builtin_init): Merge in functionality from
2706 previous prefix_all_buitins function, while making entries in the
2707 symbol table, but not modifying the builtin description itself.
2709 * src/freeze.c (reload_frozen_state): Add a useless `break;',
2710 because *many* compilers do not accept an empty `default:'.
2711 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
2712 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
2714 * configure.in: Use AC_TYPE_SIGNAL.
2715 * src/stackovf.c (setup_stackovf_trap): Use RETSIGTYPE.
2716 Reported by Robert Bernstein.
2718 * checks/Makefile.in (check): Modify PATH so check-them will find
2719 m4 in the src directory.
2720 * Makefile.in (check): Don't.
2721 Reported by Akiko Matsushita and Jim Meyering.
2723 * src/output.c (make_room_for, output_character_helper): New

2730 Tue Aug 30 01:44:29 1994 Francois Pinard (pinard@icule)
2732 * doc, src: New directories reorganizing the distribution.
2733 * doc/Makefile.in, src/Makefile.in, examples/Makefile.in: New
2734 files.
2735 * Makefile.in: Adjusted.
2736 * configure.in: Configure new Makefiles.
2738 * m4.h: Declare STRING typedef. Use it for comment and quote
2739 strings, adjusting all references. (This is the rudiments of a
2740 beginning for the eventual withdrawal of NUL terminated strings.)
2741 * output.c (shipout_text): Accept a length parameter, and use it.
2742 All callers adjusted.
2744 Mon Aug 29 12:27:19 1994 Francois Pinard (pinard@icule)
2746 * m4.h: Include <unistd.h> if it exists.

2766 * output.c (freeze_diversions): New function.
2767 * m4.h: Declare freeze_diversions.
2768 * freeze.c: Document frozen file format, revise it, call
2769 freeze_diversions to add diversions to frozen format, and code to
2770 reload them properly.
2771 * m4.c: Do not undivert automatically at end when status being
2772 frozen. Do not call builtin_init when reloading frozen state.
2774 Speed up diversion processing:
2775 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
2776 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
2777 structure and variables, cached variables out of output_diversion,
2778 reallocate_diversion_for and OUTPUT_CHARACTER.
2779 (shipout_text, make_diversion, insert_diversion): Adapted to new
2780 structures.
2781 (insert_file): Use better buffering.
2782 Reported by David MacKenzie.

2786 * Makefile.in, lib/Makefile.in, checks/Makefile.in: Arrange so
2787 dist works from another build directory.
2789 Sat Aug 27 14:32:45 1994 Francois Pinard (pinard@icule)
2791 * symtab.c (hack_all_symbols): Use hash_table_size instead of
2792 constant HASHMAX, for -H option to work better.
2794 * builtin.c (DECLARE): Simplify by using _ ().
2796 * freeze.c: New file.
2797 * Makefile.in: Compile it, distribute it.
2798 * m4.c: Recognize, document and process --freeze-state (-F) and
2799 --reload-state (-R) options. Pass a true flag to builtin_init
2800 only if no reloading some state.

2815 Mon Aug 15 12:38:05 1994 Francois Pinard (pinard@icule)
2817 * m4.c (long_options): Use "error-output", the dash was missing.
2818 Reported by Akiko Matsushita.
2820 Fri Aug 12 16:38:01 1994 Francois Pinard (pinard@icule)
2822 * m4.h: Include <sys/types.h>.
2823 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
2824 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
2825 int.
2826 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
2827 as size_t, not int.
2828 * builtin.c (dump_args): Declare len as size_t, not int.
2830 * debug.c: Prototype the forward declaration of debug_set_file.
2832 * builtin.c (m4_undivert): Replace div by file, for avoiding the

2844 * Makefile.in (distclean-local): Also delete config.cache.
2846 * m4.c (usage): Reorganize the --help output by topic. Include a
2847 description for debugging flags.
2849 Fri Jul 29 10:15:52 1994 Francois Pinard (pinard@icule)
2851 * configure.in: If sigaction is available and SA_ONSTACK defined,
2852 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
2853 defined, use sigvec. Else don't compile stackovf.c.
2854 * stackovf.c (setup_stackovf_trap): Idem.
2855 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
2856 and Simon Leinen.
2858 Thu Jul 21 22:43:17 1994 Francois Pinard (pinard@icule)
2860 * m4.c (usage): Replace printf par fputs.
2861 \f

2864 * Release 1.2
2866 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
2868 * configure.in: Check for sigaction and sigvec. Add a new delayed
2869 check for RLIMIT_STACK, combine in the checking for getrlimit.
2870 All those things are not universally available.
2871 * stackovf.c: Split setting up the trap handler and catching
2872 signals, for better taking care of various configure outcomes.
2873 * examples/stackovf.sh: Correct a typo.
2874 Reported by Eric Backus, Jim Avera and Jim Meyering.
2876 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)
2878 * ansi2knr.c: New version sent by its author, Peter Deutsch.
2880 Fri Jul 15 14:36:21 1994 Francois Pinard (pinard@icule)

2883 lib/libm4.a twice simultaneously.
2884 Reported by Jim Meyering.
2886 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
2888 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
2889 error message, for when no code possibility exists. Even if this
2890 line is completely #ifdef'ed out, it brings a syntax error.
2891 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
2893 * Makefile.in (install): Have install depend on all too, for lib
2894 to be remade as needed.
2896 * examples/stackovf.sh: Try ksh, bsh and bash for shells
2897 providing ulimit, instead of using only ksh.
2898 Reported by Jim Avera and Joseph E. Sacco.
2900 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
2902 * Makefile.in (check): Have it depend on all instead of m4. In
2903 this way, a change in lib will be detected and processed.
2905 * builtin.c (numeric_arg): Use strtol and verify the conversion,
2906 instead of using sscanf which stops as soon as there is a
2907 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
2908 and divert(1xyzzy) were all accepted without any warning or error
2909 messages.
2910 * m4.h: Declare strtol as long if not including stdlib.h.
2911 * configure.in: Check for limits.h, and replace strtol if missing.
2912 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
2913 * lib/strtol.c: New file, from elsewhere.
2914 Reported by Andreas Schwab.
2916 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
2918 * macro.c (expand_macro): Cast value to (boolean) prior to
2919 assigning it to traced.
2920 Reported by Tom McConnell.
2922 * Makefile.in (m4): Always make all in lib first.
2923 Reported by Jim Meyering.
2925 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
2927 * stackovf.c: Isolated OS-dependent sections; Improved portability,
2928 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
2929 handlers), and a default error message if the fault address is not
2930 available (when neither siginfo.h nor BSD sigcontext are supported).
2931 * configure.in: Changes for stackovf.h: Check for sigcontext,
2932 sigaction, sigstack, and define rlim_t as int if necessary.
2933 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
2934 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
2935 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
2937 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
2939 * configure.in: Use AC_SET_MAKE.
2940 * Makefile.in: Use @SET_MAKE@.
2941 Reported by Jim Meyering.
2943 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
2944 Reported by Ian Taylor.
2946 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
2948 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
2949 because siginfo.h is unrelated to standard headers, and siginfo.h
2950 is already checked for.
2951 Reported by Joseph E. Sacco.
2953 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
2954 PROTOTYPES.
2955 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
2956 AC_PROTOTYPES.
2958 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
2960 * builtin.c (substitute): Use \& to represent this part of the
2961 string which was matched by the whole regexp, instead of
2962 representing the whole string. Any usage of \0 issues a warning
2963 and acts like \&, it will disappear in some subsequent release.
2965 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
2967 * m4.c: Complete prototype for forwarded declaration of usage.
2969 * input.c (init_macro_token): Correct own reference in error
2970 message. Previous name get_macro_func was referred to instead.
2971 (next_char): Correct own reference in error message. Previous
2972 name advance_input was referred to instead.
2974 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
2975 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
2976 and_term, not_term, logical_not_term, cmp_term, shift_term,
2977 add_term, mult_term, exp_term, unary_term, simple_term): Add
2978 prototype to forwarded declarations. Declare parameter v1 as
2979 eval_t * instead of int *. Same for local variable v2 in dyadic
2980 functions. Same for result in exp_term.
2981 * builtin.c (m4_eval): Declare value as eval_t instead of int.
2982 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
2983 unsigned_eval_t instead of unsigned int. Change casts accordingly.
2984 (shipout_int): Cast first argument of ntoa to eval_t.
2985 Reported by Thorsten Ohl.
2987 * macro.c: Complete the prototypes of forwarded expand_macro and
2988 expand_token.
2989 Reported by Thorsten Ohl.
2991 * m4.h: Define voidstar as void * or char * depending on __STDC__.
2992 The Ultrix 3.1 compiler cannot do much with void pointers.
2994 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
2995 * m4.c (xfree): Replace void * by voidstar.
2996 Reported by Tom McConnell.
2998 * ansi2knr.1: New, from elsewhere.
2999 * Makefile.in (DISTFILES): Distribute ansi2knr.1
3001 * Makefile.in (stamp-h.in): Avoid running ./config.status if
3002 stamp-h does not exist yet. This avoids running it a second time
3003 just after the initial ./configure.
3004 Reported by David MacKenzie and Tom McConnell.
3006 * m4.h: Replace the enum debug_info declaration with a series of
3007 #define's. The Ultrix 3.1 compiler would otherwise need casting
3008 (int) to most references, when used in expressions.
3009 Reported by Tom McConnell.
3011 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
3013 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
3014 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
3015 calls the compiler. Previously, FP_PROTOTYPES was only calling
3016 the preprocessor; by not being subject to CFLAGS, this was
3017 discouraging those flags asking for ANSI compilation.
3018 * acconfig.h: Document HAVE_PROTOTYPES.
3019 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
3020 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
3021 Reported by Eric Backus.
3023 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
3024 from the environment. Default CFLAGS to -g if not set.
3025 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.

3027 Reported by Eric Backus and Tom McConnell.
3029 * configure.in: m4_undefine changeword before using AC_ENABLE.
3031 * m4.h: Declare prototypes for error (for ANSI compilers only),
3032 prefix_all_builtins and reference_error.
3033 Reported by Tom McConnell.
3035 * input.c (set_word_regexp): Do not try to initialize the array
3036 test from a string, this does not work with non-ANSI compilers.
3037 Reported by Eric Backus.
3039 * Makefile.in (dist): Clean examples/ before saving it.
3040 (distclean-local): Also remove stamp-h.
3041 Reported by Eric Backus.
3043 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
3044 non ANSI compilers.
3045 Reported by Tom McConnell.
3047 * checks/Makefile.in (clean): Depends on mostlyclean.
3048 (mostlyclean): New goal.
3050 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)

3062 from code provided by Pete Chown]
3063 * m4.h: Add original_text field to u_t variant of union u.
3064 Declare TOKEN_DATA_FUNC macro.
3065 * builtin.c: Declare changeword.
3066 (m4_changeword): New function.
3067 * input.c: Include "regex.h", define variables with word regexps.
3068 (input_init): Initialize the word regexp.
3069 (set_word_regexp): New.
3070 (next_token): Declare local variables, use the previous code if
3071 default_word_regexp is true. Else, match using a new code. Save
3072 the original text.
3073 * macro.c (expand_token): Ship out original text if not a macro
3074 name.
3075 Reported by Krste Asanovic and Pete Chown.
3077 [These modifs all depend upon ENABLE_CHANGEWORD]
3078 * m4.h: Declare external user_word_regexp.
3079 * m4.c: Declare user_word_regexp, and initialize it from
3080 --word-regexp or -W, or NULL if not specified.

3085 agree with it.
3087 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
3088 * checks/Makefile.in: Empty the suffix list.
3089 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.

3093 value.
3094 * m4.h: Declare nesting_limit as external.
3095 * macro.c (expand_macro): Stop execution whenever nesting limit
3096 is exceeded.
3097 Reported by Bengt Mertensson.
3099 * eval.c (evaluate): Diagnose excess characters in eval input.
3100 Things like `eval(08)' used to return 0 with no diagnostic.
3102 * m4.h: Capitalize first letter of all macro arguments in
3103 definitions.
3105 * m4.c: Declare warning_status, initialize it to 0. Add new
3106 option -E, or --fatal-warnings, which sets warning_status to
3107 EXIT_FAILURE instead.
3108 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
3109 EXIT_FAILURE if not otherwise done by header files.
3110 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.

3117 * examples/include.m4: Include incl-test.m4 instead of
3118 incl_test.m4.
3119 * examples/multiquotes.m4: Renamed from multi-quotes.m.
3121 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
3123 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
3124 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
3125 also tested it on a Sun Sparc workstation running SunOS 4.x.
3127 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
3128 49.format check, abusing a `union values' argument with sprintf
3129 without selecting the proper field. Now, save the formatting type
3130 first, delaying the fetch of the corresponding argument.
3131 Reported by Joseph E. Sacco and Tom Quinn.
3133 * format.c (format): Remove const from char *fmt declaration when
3134 not HAVE_EFGCVT, because a NUL may be forced into it.
3136 * m4.h: Declare atof() when not STDC_HEADERS.
3137 Reported by Joseph E. Sacco.
3139 * Regenerate configure using Autoconf 1.11, this corrects a
3140 problem about an incorrect cpp seting on NeXT 3.1.
3141 Reported by Alexander Lehmann.
3143 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
3145 * m4.h (_): Change argument from `x' to `Args'.
3147 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
3149 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
3150 bringing more evil than good on a few systems.

3163 substitute ${U}stackovf.o for STACKOVF.
3164 * acconfig.h: Declare USE_STACKOVF.
3165 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
3166 * m4.h: Declare setup_stackovf_trap().
3167 * m4.c: Call setup_stackovf_trap().
3168 * tests/stackovf_test.sh: New file.
3170 Wed Apr 13 14:10:30 1994 Francois Pinard (pinard@icule)
3172 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
3174 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
3176 Sun Jan 30 14:24:19 1994 (pinard at icule)
3178 * m4.h: Remove definition of volatile, not used anymore.
3179 Reported by Jim Meyering and Joseph E. Sacco.
3181 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
3182 of `if ... else /* nothing */' for if macros.
3183 Reported by Jim Meyering.
3185 * builtin.c (m4_regexp): Reorganize the code for avoiding a
3186 warning from gcc about `repl' possibly used before defined.
3187 Reported by Jim Meyering.
3189 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
3190 Reported by Jim Meyering.
3192 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
3194 * m4.h: Move the conditional definition of volatile after the
3195 inclusion of system files, because they may define it first.
3197 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
3199 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
3200 get around a problem with Alpha make seeing a syntax error, there.
3201 Reported by Vern Paxson.
3203 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
3205 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.

3216 * m4.c: Initialize show_help and show_version to zero.
3218 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
3219 Use them in exit() and usage() calls.
3221 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
3223 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
3224 syserr() macro. Delete errref, add reference_error and M4ERROR.
3225 * m4.c: Replace errref, which was returning an input reference
3226 string, with reference_error, which prints it on standard error.
3227 * builtin.c, output.c: Use errno as second parameter to error,
3228 instead of using syserr() with %s.
3229 * *.c: Use M4ERROR instead of error: no more errref() with %s.
3230 Doing so, the program name appears after the input reference
3231 instead of before, which eases M-x next-error processing.
3233 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
3235 * checks/get-them: Escape braces with backslashes in patterns,
3236 because HPUX-9.01 awk needs this.

3239 Mon Nov 22 10:55:52 1993 Francois Pinard (pinard@icule)
3241 * builtin.c: Declare "FILE *popen ();".

3245 Declare xrealloc, for use in errref().
3246 * m4.c: Delete error_message_prefix() function, add errref().
3247 * *.c: Use error() systematically in place of all error macros,
3248 now that error() flushes stdout first. Make needed adjustments.
3250 * m4.h: Remove const in sys_errlist[] declaration, it creates
3251 conflicts on SGI and Alpha.
3252 Reported by Kaveh R. Ghazi.
3254 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)
3256 * m4.c: Include <getopt.h> instead of "getopt.h".

3270 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
3272 * input.c (input_init): Initialize quote and comment strings
3273 explicitely instead of calling set_quotes and set_comment: by
3274 doing so, we ensure we do not free uninitialized variables.
3276 * checks/check-them: Reverse arguments to both diff, so the
3277 expected is on the left and the obtained on the right.
3279 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
3280 macros. Delete declarations for m4error, warning, fatal and
3281 internal_error, add declaration for error_message_prefix.
3282 * m4.c: Delete m4error, warning, fatal and internal_error
3283 routines, add error_message_prefix routine.
3284 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
3285 warning with WARNING*, fatal with FATAL* and internal_error with
3286 INTERNAL_ERROR*.
3287 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
3288 this is not needed anymore.
3290 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
3291 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
3292 and debug_message, add declaration for debug_message_prefix.

3294 Delete debug_print and debug_message routines, add
3295 debug_message_prefix routine.
3296 * builtin.c, debug.c: Replace debug_print routine calls with
3297 DEBUG_PRINT* macro calls.

3303 (trace_format): Use stdarg instead of varargs if __STDC__.
3305 * configure.in: Remove checks for vfprintf and _doprnt. These
3306 implementations use varargs tricks which are not portable enough.
3307 * lib/vfprintf.c: Deleted.
3308 * lib/_doprnt.c: Deleted.
3309 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.
3310 Reported by Joel Sherrill.

3328 * Makefile.in (m4.dvi): Use m4.texinfo instead of m4.texi.
3329 Reported by Joel Sherrill.
3331 * builtin.c (prefix_all_builtins): Instead of the table size, use
3332 the null entry at end for stopping the loop. It was overwritten.
3333 Reported by Andreas Schwab and Jim Meyering.
3335 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
3336 Reported by Kaveh R. Ghazi.

3523 Sat Feb 6 14:59:22 1993 Francois Pinard (pinard@icule)
3525 * Makefile.in, lib/Makefile.in, check/Makefile.in: In dist goals,
3526 ensure 777 mode for directories, so older tar's will restore file
3527 modes properly.
3529 Sun Jan 17 15:38:05 1993 Francois Pinard (pinard@icule)
3531 * Makefile.in, lib/Makefile.in: Put $(CFLAGS) after $(CPPFLAGS),
3532 so the installer can override automatically configured choices.
3533 Reported by Karl Berry.
3535 Fri Jan 15 16:07:00 1993 Francois Pinard (pinard@icule)
3537 * lib/vfprintf.c: Stolen from Oleo distribution and adapted. The
3538 previous version was not working properly on m68k-hp-bsd4.3.
3539 Reported by Roland McGrath.
3541 * lib/_doprnt.c: Stolen from Oleo distribution.
3542 * configure.in: Check for _doprnt.c if vfprintf.c selected.
3543 * lib/Makefile.in: Distribute _doprnt.c.
3544 Do not distribute regex.[ch].old anymore.
3546 Fri Jan 1 19:42:23 1993 Francois Pinard (pinard at icule)
3548 * Makefile.in, lib/Makefile.in: Reinstate $(CPPFLAGS), use it.
3549 Richard wants it there.
3551 Sun Dec 27 07:01:54 1992 Francois Pinard (pinard at icule)
3553 * Makefile.in: Add DEFS to MDEFINES.
3554 * lib/Makefile.in (.c.o): Remove $(CPPFLAGS).
3555 (libm4.a): Remove the library before creating it.
3556 (distclean): Remove tags and TAGS too.
3558 Wed Dec 23 12:46:55 1992 Francois Pinard (pinard at icule)
3560 * Makefile.in (dvi, m4.dvi): New goals.
3562 * builtin.c, eval.c, format.c, input.c, m4.[ch], m4.texinfo,
3563 macro.c, output.c, path.c, symtab.c: Change Copyright from
3564 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.
3566 * examples/divert.m4: Deleted, this bug has been corrected.
3568 * Makefile.in (texclean, mostlyclean): New goals.
3570 * Makefile.in (clean): Remove clutter from ansi2knr.
3571 Reported by Pierre Gaumond.
3572 Reported by Greg A. Woods.
3574 Sun Dec 20 10:40:20 1992 Francois Pinard (pinard at icule)
3576 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user
3577 might well use CFLAGS is s/he needs it.
3579 * Makefile.in: Allow installation of info files from a separate
3580 build directory.
3581 Reported by Jason Merrill.
3582 Reported by David MacKenzie.
3583 Reported by Skip Montanaro.
3584 Reported by Erez Zadok.

3587 Sat Dec 19 08:21:34 1992 Francois Pinard (pinard at icule)
3589 * Release 1.0.3
3590 This is still a beta release for the future GNU m4 version 1.1.
3592 * lib/alloca.c: New, from elsewhere.
3593 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
3595 * m4.h: Do not define index/rindex if already defined. If
3596 FALSE/TRUE are already defined, do not redefine them, but merely
3597 define boolean typedef to int.
3599 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
3600 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
3601 because some C compilers do not like connectives with #ifdef.
3602 * m4.h: Define `volatile' only if __GNUC__, instead of once for
3603 __GNUC__ and once for __STDC__.
3604 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
3606 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
3607 Makefile dependencies. Without it, make keeps destroying and
3608 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
3610 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
3611 to diversion/DIVERSION, this was a spelling error.
3613 * m4.c: Declare version[], remove #include "version.h".
3614 * version.h: Deleted.
3615 * Makefile.in: Remove references to version.h.
3617 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
3618 production, by using a simpler and more robust algorithm. This
3619 solves the problem of synclines sometimes written in the middle of
3620 an output line. Delete sync_line() and output_lines variable.
3621 * m4.h: Remove sync_line prototype and output_lines declaration.
3622 * input.c (next_char), output.c (shipout_text): Remove references
3623 to output_lines.
3624 * input.c (push_file, pop_file): Merely put the value -1 in
3625 output_current_line instead of calling sync_line, for delaying a
3626 single `#line NUM FILE' before next output line. Do not test
3627 for sync_output, because this is unnecessary clutter.
3628 * output.c (make_divertion, insert_divertion): Idem.
3629 * input.c: Rename must_advance_line to start_of_input_line, for
3630 consistency.
3632 * debug.c (trace_header): Select a new debug line format, which
3633 better complies with GNU standards for formatting error messages.
3634 With option `-dfl', M-x next-error might be used on the output.
3635 * m4.c (vmesg): Adjust format of error output to GNU standards.
3636 * m4.texinfo: Adjust examples for `make check' to work.
3638 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
3639 case for enum debug_info constants, which were all lower case.
3641 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
3642 re_search_2.
3643 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
3644 collected patches. I tried a few times using newer regex.[ch], it
3645 mysteriously stopped aborting with this one. Insecure feeling...
3646 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
3648 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
3650 * m4.c: Change `--no-warnings' to `--silent'.
3651 Reported by David MacKenzie.
3653 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
3654 leave it off for now. See comment in m4.c for justification.
3655 Reported by David MacKenzie.
3657 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
3658 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
3660 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
3662 * Makefile.in: Ensure recursive cleaning is done before local
3663 cleaning for all clean goals.
3665 * builtin.c (ntoa): Ensure the value is always interpreted as a
3666 signed quantity, whatever the radix is.
3668 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
3670 * builtin.c, format.c, input.c: Split long lines.
3671 * m4.c: Use typedef macro_definition instead of struct
3672 macro_definition.
3673 * symtab.c: Use typedef symbol instead of struct symbol.
3675 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
3677 * *.[ch]: Remove all trailing whitespace, in code and comments.
3679 * configure.in: Find some awk.
3680 * Makefile.in: Add $(AWK) to MDEFINES.
3681 * checks/Makefile.in: Transmit $(AWK) to get_them.
3682 * checks/get_them: Use $AWK instead of gawk. Add a close in the
3683 awk script when switching files, because without this, mawk runs
3684 out of file descriptors.
3686 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
3688 * Makefile.in (realclean): Delete m4.info*.
3689 Reported by Jim Meyering.
3691 * Makefile.in: Adjust and link with checks/Makefile.
3692 * checks/Makefile.in: New.
3693 * configure.in: Output checks/Makefile.
3695 * checks/get_them: Have the dnl header of each test more
3696 recognizable by next-error, also use a better message.
3698 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
3700 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
3701 And use that only if __GNUC__ since we're using it's GCC-specific
3702 semantics that tell the compiler the associated function doesn't
3703 return.
3705 * builtin.c (substitute): Don't use character as an array index.
3706 (dumpdef_cmp): Make formal arguments `const void *' to avoid
3707 warnings with gcc -W -Wall on systems with qsort prototype.
3708 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
3709 from gcc -W -Wall.
3711 * eval.c (most functions): Add parentheses to assignments used
3712 as truth values go avoid warnings from gcc -Wall.
3714 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
3715 any functions that don't need external scope.
3717 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
3718 (many functions and arrays): Declare `const'.
3720 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
3722 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
3723 removing the declaration from m4.h. Also rename false to FALSE
3724 and true to TRUE.
3726 * lib/Makefile.in (Makefile): New goal.
3728 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
3729 so heavily loaded. It gets more easily overridable, calling make.
3730 Reported by Jim Meyering.
3732 * Makefile.in (dist): Get .fname from the current directory name,
3733 instead of from version.h. I need updating many files manually,
3734 when the version changes, version.h is just one of them.
3736 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
3738 * m4.h: Remove the tag `boolean' on the enum introducing typedef
3739 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
3740 Reported by Tom McConnell.
3742 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
3744 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
3745 39.cleardiv, which were describing missing or spurious newlines.
3746 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
3747 do not depend on machine word size, `/bin/false' implementation,
3748 or `wc' output format. `make check' is more dependable, now.
3750 * checks/check_them: Summarize the failed tests by listing their
3751 name, at end. If none, issue `All checks successful'. Output
3752 `Checking' instead of `Input file:'.
3754 * checks/get_them, checks/check_them: Reindented.
3756 * Makefile.in (dist): chmod a+r before making the tar file.
3758 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
3760 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
3762 * input.c (next_token): Reinitialize token_buttom just after using
3763 it as a watermark with obstack_free. Or else, a future token, big
3764 enough for triggering reallocation of the obstack chunk, could
3765 void the initialized value of token_buttom, later causing panic in
3766 obstack_free. Rename token_buttom to token_bottom everywhere.
3768 * m4.h: Before declaring errno, first include <errno.h> and
3769 ensure that it does not define errno.
3770 Reported by Richard Stallman.
3772 Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule)
3774 * builtin.c: Define and use DECLARE macro for builtins.
3776 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
3777 argument, this is a common idiom for introducing long comments.
3779 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
3780 arguments. The last argument was silently ignored.
3782 * m4.c (cmd_error): Add a missing semicolon before va_end().
3784 Tue Nov 10 08:57:05 1992 Francois Pinard (pinard at icule)
3786 * Makefile.in: Now handle protoized sources. Define and use U.
3787 Compile and use ansi2knr with old compilers. Update DISTFILES.
3788 Add `aclocal.m4' to `configure' dependencies.
3789 * ansi2knr.c: New, from Ghostscript distribution.
3790 * configure.in: Define U through FP_PROTOTYPES for old compilers.
3791 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
3792 * aclocal.m4: New, provide FP_PROTOTYPES.
3793 * m4.h: Conditionnaly protoized through Args, save for varags.
3794 * builtin.c: Protoized. Then:
3795 Include <sys/types.h> if size_t is not defined, before "regex.h".
3796 (m4_ifelse): Fetch built-in name properly for diagnostic.
3797 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
3798 (m4_regexp): Add const to `msg' declaration.
3799 (m4_patsubst): Add const to `msg' declaration.
3800 * debug.c: Protoized, save for varargs.
3801 * eval.c: Protoized.
3802 * format.c: Protoized.
3803 * input.c: Protoized.
3804 * m4.c: Protoized, save for varargs. Then:
3805 (xfree): Accept void * instead of char *.
3806 (xmalloc): Return void * instead of char *.
3807 (xrealloc): Accept and return void * instead of char *.
3808 * macro.c: Protoized.
3809 * output.c: Protoized.
3810 * path.c: Protoized. Then cast some (char *) over xmalloc's.
3811 * symtab.c: Protoized.
3813 Fri Nov 6 02:05:21 1992 Francois Pinard (pinard at icule)
3815 * m4.texinfo: Remove directory from diagnostics in 30.include,
3816 51.eval, 56.errprint and 57.m4exit tests.
3818 * m4.h: Remove declarations for int or void system functions, they
3819 cause more conflicting trouble than they make good.
3821 * configure.in: Avoid configuration header file. Add some tests.
3822 * m4.h: Remove #include "config.h".
3823 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
3824 Then, rewritten for better compliance with GNU standards.
3826 Thu Nov 5 12:37:13 1992 Francois Pinard (pinard at icule)
3828 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
3829 because of a misplaced #endif.
3831 * Many *.[hc] files: Correct intra-line spacing here and there,
3832 according to GNU indent 1.6 advice.
3834 * configure.in: New, using Autoconf 1.2.
3835 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.

3841 Reported by Jason Merrill.
3843 * Delete .vers, etc/newdist.sh, etc/newvers.sh and
3844 etc/nextvers.sh. Release numbers will be edited `by hand'.
3845 * version.h: De-automatize, force value in.
3847 * m4.c: Changes in order to use a newer getopt.h.
3848 Reported by David MacKenzie.
3850 * checks/: New name for examples/.
3851 * checks/get_them: New location for etc/get_examples.
3852 * checks/check_them: New location for etc/check_examples.
3853 * Makefile.in, checks/get_them, checks/check_them: Adjust.
3854 * lib/vfprintf.c: New location for etc/vfprintf.c.
3855 * Delete empty etc/.
3856 * examples/: New name for test/.
3858 Tue Mar 10 00:29:46 1992 Francois Pinard (pinard at icule)
3860 * Makefile.in (check): Add m4 as dependency.
3862 * m4.c: Accept --no-warnings instead of --no_warnings, and
3863 --no-gnu-extensions instead of --no_gnu_extensions. Make the
3864 usage message more informative.
3865 Reported by David MacKenzie.

3881 Reported by Richard Stallman.
3883 * config/hmake-unicos, config/s-unicos.h: New files.
3884 Reported by Hal Peterson.
3886 * eval.c (exp_term): Have N^0 return 1.
3887 Reported by Michael Fetterman.
3889 * eval.c, input.c, m4.h: Remove last comma in enums.
3890 Reported by Mike Lijewski.

3919 Francois Pinard and Roland H. Pesch for providing me with reports.
3921 * The builtins incr and decr are now implemented without use of
3922 eval.
3924 * The builtin indir is added, to allow for indirect macro calls
3925 (allows use of "illegal" macro names).
3927 * The debugging and tracing facilities has been enhanced
3928 considerably. See the manual for details.
3930 * The -tMACRO option is added, marks MACRO for tracing as soon
3931 as it is defined.
3933 * Builtins are traced after renaming iff they were before.
3935 * Named files can now be undiverted.
3937 * The -Nnum option can be used to increase the number of
3938 divertions available.
3940 * Calling changecom without arguments now disables all comment
