2109 of $U, put underline in extensions rather than in basenames. Use
2110 implicit rules, now that regularity makes this possible.

2165 * src/stackovf.c: Declare the handler_t typedef earlier in the
2166 code, use it for stackovf_handler.
2167 (setup_stackovf_trap): Use RETSIGTYPE instead of void while
2168 casting sigsegv_handler.
2169 Reported by Robert Bernstein.
2171 * src/m4.c (main): Initialize program_name to argv[0] without

2183 (TAGS): Make in $(srcdir).
2185 * configure.in: Use `choke me' in test, like everywhere!
2187 * {doc,examples,lib,src}/Makefile.in (check): Deleted, as
2188 unreacheable and useless.
2190 * doc/Makefile.in (texclean): Deleted, merged in mostlyclean.

2198 * Makefile.in (distclean, realclean): Instead of recursively
2199 calling $(MAKE) for the -local part, allow parallel execution of
2200 -recursive and -local, only delay the removal of config.status,
2201 which is repeated in both goals.
2203 Tue Sep 13 19:21:05 1994 Francois Pinard (pinard@icule)
2206 * Makefile.in: Group all *clean-recursive goals in one, using sed
2207 to remove `-recursive' while calling make recursively. Also, use
2208 a subshell for each recursive $(MAKE).
2209 Reported by Jim Meyering.

2212 Reported by Kaveh R. Ghazi.
2214 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS

2275 * src/m4.h: Adjust declaration for prefix_all_buitins.
2276 * src/builtin.c (builtin_init): Merge in functionality from
2277 previous prefix_all_buitins function, while making entries in the
2278 symbol table, but not modifying the builtin description itself.
2280 * src/freeze.c (reload_frozen_state): Add a useless `break;',
2281 because *many* compilers do not accept an empty `default:'.
2282 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
2283 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
2285 * configure.in: Use AC_TYPE_SIGNAL.
2286 * src/stackovf.c (setup_stackovf_trap): Use RETSIGTYPE.

2303 * doc, src: New directories reorganizing the distribution.
2304 * doc/Makefile.in, src/Makefile.in, examples/Makefile.in: New
2306 * Makefile.in: Adjusted.
2307 * configure.in: Configure new Makefiles.
2309 * m4.h: Declare STRING typedef. Use it for comment and quote
2310 strings, adjusting all references. (This is the rudiments of a
2311 beginning for the eventual withdrawal of NUL terminated strings.)
2312 * output.c (shipout_text): Accept a length parameter, and use it.
2313 All callers adjusted.
2315 Mon Aug 29 12:27:19 1994 Francois Pinard (pinard@icule)

2338 * m4.h: Declare freeze_diversions.
2339 * freeze.c: Document frozen file format, revise it, call
2340 freeze_diversions to add diversions to frozen format, and code to
2341 reload them properly.
2342 * m4.c: Do not undivert automatically at end when status being
2343 frozen. Do not call builtin_init when reloading frozen state.
2345 Speed up diversion processing:
2346 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
2347 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
2348 structure and variables, cached variables out of output_diversion,
2349 reallocate_diversion_for and OUTPUT_CHARACTER.
2350 (shipout_text, make_diversion, insert_diversion): Adapted to new

2360 Sat Aug 27 14:32:45 1994 Francois Pinard (pinard@icule)
2362 * symtab.c (hack_all_symbols): Use hash_table_size instead of
2363 constant HASHMAX, for -H option to work better.
2365 * builtin.c (DECLARE): Simplify by using _ ().
2367 * freeze.c: New file.
2368 * Makefile.in: Compile it, distribute it.
2369 * m4.c: Recognize, document and process --freeze-state (-F) and
2370 --reload-state (-R) options. Pass a true flag to builtin_init
2371 only if no reloading some state.
2372 * builtin.c (define_builtin): Remove static specifier.
2373 (find_builtin_by_name): Remove static specifier.
2374 (builtin_init): Accept and obey a flag argument.

2386 Mon Aug 15 12:38:05 1994 Francois Pinard (pinard@icule)
2388 * m4.c (long_options): Use "error-output", the dash was missing.
2389 Reported by Akiko Matsushita.
2391 Fri Aug 12 16:38:01 1994 Francois Pinard (pinard@icule)
2393 * m4.h: Include <sys/types.h>.
2394 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
2395 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
2397 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
2399 * builtin.c (dump_args): Declare len as size_t, not int.
2401 * debug.c: Prototype the forward declaration of debug_set_file.
2403 * builtin.c (m4_undivert): Replace div by file, for avoiding the
2404 shadowing of this variable.

2418 description for debugging flags.
2420 Fri Jul 29 10:15:52 1994 Francois Pinard (pinard@icule)
2422 * configure.in: If sigaction is available and SA_ONSTACK defined,
2423 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
2424 defined, use sigvec. Else don't compile stackovf.c.
2425 * stackovf.c (setup_stackovf_trap): Idem.
2426 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
2429 Thu Jul 21 22:43:17 1994 Francois Pinard (pinard@icule)
2431 * m4.c (usage): Replace printf par fputs.
2433 Mon Jul 18 23:48:23 1994 Francois Pinard (pinard@icule)
2437 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
2439 * configure.in: Check for sigaction and sigvec. Add a new delayed
2440 check for RLIMIT_STACK, combine in the checking for getrlimit.
2441 All those things are not universally available.
2442 * stackovf.c: Split setting up the trap handler and catching
2443 signals, for better taking care of various configure outcomes.
2444 * examples/stackovf.sh: Correct a typo.
2445 Reported by Eric Backus, Jim Avera and Jim Meyering.
2447 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)
2449 * ansi2knr.c: New version sent by its author, Peter Deutsch.
2451 Fri Jul 15 14:36:21 1994 Francois Pinard (pinard@icule)
2453 * Makefile.in: Modify so parallel make will not try making
2454 lib/libm4.a twice simultaneously.
2455 Reported by Jim Meyering.
2457 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
2459 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
2460 error message, for when no code possibility exists. Even if this
2461 line is completely #ifdef'ed out, it brings a syntax error.
2462 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
2464 * Makefile.in (install): Have install depend on all too, for lib
2465 to be remade as needed.
2467 * examples/stackovf.sh: Try ksh, bsh and bash for shells
2468 providing ulimit, instead of using only ksh.
2469 Reported by Jim Avera and Joseph E. Sacco.
2471 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
2473 * Makefile.in (check): Have it depend on all instead of m4. In
2474 this way, a change in lib will be detected and processed.
2476 * builtin.c (numeric_arg): Use strtol and verify the conversion,
2477 instead of using sscanf which stops as soon as there is a
2478 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
2479 and divert(1xyzzy) were all accepted without any warning or error
2481 * m4.h: Declare strtol as long if not including stdlib.h.
2482 * configure.in: Check for limits.h, and replace strtol if missing.
2483 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
2484 * lib/strtol.c: New file, from elsewhere.
2485 Reported by Andreas Schwab.
2487 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
2489 * macro.c (expand_macro): Cast value to (boolean) prior to
2490 assigning it to traced.
2491 Reported by Tom McConnell.
2493 * Makefile.in (m4): Always make all in lib first.
2494 Reported by Jim Meyering.
2496 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
2498 * stackovf.c: Isolated OS-dependent sections; Improved portability,
2499 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
2500 handlers), and a default error message if the fault address is not
2501 available (when neither siginfo.h nor BSD sigcontext are supported).
2502 * configure.in: Changes for stackovf.h: Check for sigcontext,
2503 sigaction, sigstack, and define rlim_t as int if necessary.
2504 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
2505 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
2506 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
2508 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
2510 * configure.in: Use AC_SET_MAKE.
2511 * Makefile.in: Use @SET_MAKE@.
2512 Reported by Jim Meyering.
2514 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
2515 Reported by Ian Taylor.
2517 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
2519 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
2520 because siginfo.h is unrelated to standard headers, and siginfo.h
2521 is already checked for.
2522 Reported by Joseph E. Sacco.
2524 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
2526 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
2529 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
2531 * builtin.c (substitute): Use \& to represent this part of the
2532 string which was matched by the whole regexp, instead of
2533 representing the whole string. Any usage of \0 issues a warning
2534 and acts like \&, it will disappear in some subsequent release.
2536 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
2538 * m4.c: Complete prototype for forwarded declaration of usage.
2540 * input.c (init_macro_token): Correct own reference in error
2541 message. Previous name get_macro_func was referred to instead.
2542 (next_char): Correct own reference in error message. Previous
2543 name advance_input was referred to instead.
2545 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
2546 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
2547 and_term, not_term, logical_not_term, cmp_term, shift_term,
2548 add_term, mult_term, exp_term, unary_term, simple_term): Add
2549 prototype to forwarded declarations. Declare parameter v1 as
2550 eval_t * instead of int *. Same for local variable v2 in dyadic
2551 functions. Same for result in exp_term.
2552 * builtin.c (m4_eval): Declare value as eval_t instead of int.
2553 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
2554 unsigned_eval_t instead of unsigned int. Change casts accordingly.
2555 (shipout_int): Cast first argument of ntoa to eval_t.
2556 Reported by Thorsten Ohl.
2558 * macro.c: Complete the prototypes of forwarded expand_macro and
2560 Reported by Thorsten Ohl.
2562 * m4.h: Define voidstar as void * or char * depending on __STDC__.
2563 The Ultrix 3.1 compiler cannot do much with void pointers.
2565 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
2566 * m4.c (xfree): Replace void * by voidstar.
2567 Reported by Tom McConnell.
2569 * ansi2knr.1: New, from elsewhere.
2570 * Makefile.in (DISTFILES): Distribute ansi2knr.1
2572 * Makefile.in (stamp-h.in): Avoid running ./config.status if
2573 stamp-h does not exist yet. This avoids running it a second time
2574 just after the initial ./configure.
2575 Reported by David MacKenzie and Tom McConnell.
2577 * m4.h: Replace the enum debug_info declaration with a series of
2578 #define's. The Ultrix 3.1 compiler would otherwise need casting
2579 (int) to most references, when used in expressions.
2580 Reported by Tom McConnell.
2582 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
2584 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
2585 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
2586 calls the compiler. Previously, FP_PROTOTYPES was only calling
2587 the preprocessor; by not being subject to CFLAGS, this was
2588 discouraging those flags asking for ANSI compilation.
2589 * acconfig.h: Document HAVE_PROTOTYPES.
2590 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
2591 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
2592 Reported by Eric Backus.
2594 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
2595 from the environment. Default CFLAGS to -g if not set.
2596 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
2597 * lib/Makefile.in: Have CFLAGS substituted from configure.
2598 Reported by Eric Backus and Tom McConnell.
2600 * configure.in: m4_undefine changeword before using AC_ENABLE.
2602 * m4.h: Declare prototypes for error (for ANSI compilers only),
2603 prefix_all_builtins and reference_error.
2604 Reported by Tom McConnell.
2606 * input.c (set_word_regexp): Do not try to initialize the array
2607 test from a string, this does not work with non-ANSI compilers.
2608 Reported by Eric Backus.
2610 * Makefile.in (dist): Clean examples/ before saving it.
2611 (distclean-local): Also remove stamp-h.
2612 Reported by Eric Backus.
2614 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
2616 Reported by Tom McConnell.
2618 * checks/Makefile.in (clean): Depends on mostlyclean.
2619 (mostlyclean): New goal.
2621 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
2623 * Makefile.in (DISTFILES): Distribute install.sh.
2624 * install.sh: New file, copied from elsewhere.
2625 Reported by Assar Westerlund and Kaveh R. Ghazi.
2627 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
2629 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
2630 * acconfig.h: Explain ENABLE_CHANGEWORD.
2632 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
2633 from code provided by Pete Chown]
2634 * m4.h: Add original_text field to u_t variant of union u.
2635 Declare TOKEN_DATA_FUNC macro.

2668 Reported by Bengt Mertensson.
2670 * eval.c (evaluate): Diagnose excess characters in eval input.
2671 Things like `eval(08)' used to return 0 with no diagnostic.
2673 * m4.h: Capitalize first letter of all macro arguments in
2676 * m4.c: Declare warning_status, initialize it to 0. Add new

2692 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
2694 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
2695 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
2696 also tested it on a Sun Sparc workstation running SunOS 4.x.
2698 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
2699 49.format check, abusing a `union values' argument with sprintf
2700 without selecting the proper field. Now, save the formatting type
2701 first, delaying the fetch of the corresponding argument.
2702 Reported by Joseph E. Sacco and Tom Quinn.
2704 * format.c (format): Remove const from char *fmt declaration when
2705 not HAVE_EFGCVT, because a NUL may be forced into it.

2754 Reported by Jim Meyering.
2756 * builtin.c (m4_regexp): Reorganize the code for avoiding a
2757 warning from gcc about `repl' possibly used before defined.
2758 Reported by Jim Meyering.
2760 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
2761 Reported by Jim Meyering.
2763 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
2765 * m4.h: Move the conditional definition of volatile after the
2766 inclusion of system files, because they may define it first.
2768 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
2770 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to

2794 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
2795 syserr() macro. Delete errref, add reference_error and M4ERROR.
2796 * m4.c: Replace errref, which was returning an input reference
2797 string, with reference_error, which prints it on standard error.
2798 * builtin.c, output.c: Use errno as second parameter to error,
2799 instead of using syserr() with %s.
2800 * *.c: Use M4ERROR instead of error: no more errref() with %s.
2801 Doing so, the program name appears after the input reference
2802 instead of before, which eases M-x next-error processing.
2804 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
2806 * checks/get-them: Escape braces with backslashes in patterns,

2817 * m4.c: Delete error_message_prefix() function, add errref().
2818 * *.c: Use error() systematically in place of all error macros,
2819 now that error() flushes stdout first. Make needed adjustments.

2843 * input.c (input_init): Initialize quote and comment strings
2844 explicitely instead of calling set_quotes and set_comment: by

2848 expected is on the left and the obtained on the right.
2850 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
2851 macros. Delete declarations for m4error, warning, fatal and
2852 internal_error, add declaration for error_message_prefix.
2853 * m4.c: Delete m4error, warning, fatal and internal_error
2854 routines, add error_message_prefix routine.
2855 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
2856 warning with WARNING*, fatal with FATAL* and internal_error with
2858 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
2859 this is not needed anymore.
2861 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and

2865 Delete debug_print and debug_message routines, add
2866 debug_message_prefix routine.
2867 * builtin.c, debug.c: Replace debug_print routine calls with

2874 (trace_format): Use stdarg instead of varargs if __STDC__.
2876 * configure.in: Remove checks for vfprintf and _doprnt. These
2877 implementations use varargs tricks which are not portable enough.

3152 Reported by Jason Merrill.
3153 Reported by David MacKenzie.
3154 Reported by Skip Montanaro.
3155 Reported by Erez Zadok.

3158 Sat Dec 19 08:21:34 1992 Francois Pinard (pinard at icule)
3161 This is still a beta release for the future GNU m4 version 1.1.
3163 * lib/alloca.c: New, from elsewhere.
3164 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
3166 * m4.h: Do not define index/rindex if already defined. If
3167 FALSE/TRUE are already defined, do not redefine them, but merely
3168 define boolean typedef to int.
3170 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
3171 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
3172 because some C compilers do not like connectives with #ifdef.
3173 * m4.h: Define `volatile' only if __GNUC__, instead of once for
3174 __GNUC__ and once for __STDC__.
3175 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
3177 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
3178 Makefile dependencies. Without it, make keeps destroying and
3179 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
3181 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
3182 to diversion/DIVERSION, this was a spelling error.
3184 * m4.c: Declare version[], remove #include "version.h".
3185 * version.h: Deleted.
3186 * Makefile.in: Remove references to version.h.
3188 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
3189 production, by using a simpler and more robust algorithm. This
3190 solves the problem of synclines sometimes written in the middle of
3191 an output line. Delete sync_line() and output_lines variable.
3192 * m4.h: Remove sync_line prototype and output_lines declaration.
3193 * input.c (next_char), output.c (shipout_text): Remove references
3195 * input.c (push_file, pop_file): Merely put the value -1 in
3196 output_current_line instead of calling sync_line, for delaying a
3197 single `#line NUM FILE' before next output line. Do not test
3198 for sync_output, because this is unnecessary clutter.
3199 * output.c (make_divertion, insert_divertion): Idem.
3200 * input.c: Rename must_advance_line to start_of_input_line, for
3203 * debug.c (trace_header): Select a new debug line format, which
3204 better complies with GNU standards for formatting error messages.
3205 With option `-dfl', M-x next-error might be used on the output.
3206 * m4.c (vmesg): Adjust format of error output to GNU standards.
3207 * m4.texinfo: Adjust examples for `make check' to work.
3209 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
3210 case for enum debug_info constants, which were all lower case.
3212 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
3214 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
3215 collected patches. I tried a few times using newer regex.[ch], it
3216 mysteriously stopped aborting with this one. Insecure feeling...
3217 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
3219 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
3221 * m4.c: Change `--no-warnings' to `--silent'.
3222 Reported by David MacKenzie.
3224 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
3225 leave it off for now. See comment in m4.c for justification.
3226 Reported by David MacKenzie.
3228 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
3229 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
3231 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
3233 * Makefile.in: Ensure recursive cleaning is done before local
3234 cleaning for all clean goals.
3236 * builtin.c (ntoa): Ensure the value is always interpreted as a
3237 signed quantity, whatever the radix is.
3239 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
3241 * builtin.c, format.c, input.c: Split long lines.
3242 * m4.c: Use typedef macro_definition instead of struct
3244 * symtab.c: Use typedef symbol instead of struct symbol.
3246 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
3248 * *.[ch]: Remove all trailing whitespace, in code and comments.
3250 * configure.in: Find some awk.
3251 * Makefile.in: Add $(AWK) to MDEFINES.
3252 * checks/Makefile.in: Transmit $(AWK) to get_them.
3253 * checks/get_them: Use $AWK instead of gawk. Add a close in the
3254 awk script when switching files, because without this, mawk runs
3255 out of file descriptors.
3257 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
3259 * Makefile.in (realclean): Delete m4.info*.
3260 Reported by Jim Meyering.
3262 * Makefile.in: Adjust and link with checks/Makefile.
3263 * checks/Makefile.in: New.
3264 * configure.in: Output checks/Makefile.
3266 * checks/get_them: Have the dnl header of each test more
3267 recognizable by next-error, also use a better message.
3269 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
3271 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
3272 And use that only if __GNUC__ since we're using it's GCC-specific
3273 semantics that tell the compiler the associated function doesn't
3276 * builtin.c (substitute): Don't use character as an array index.
3277 (dumpdef_cmp): Make formal arguments `const void *' to avoid
3278 warnings with gcc -W -Wall on systems with qsort prototype.
3279 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
3282 * eval.c (most functions): Add parentheses to assignments used
3283 as truth values go avoid warnings from gcc -Wall.
3285 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
3286 any functions that don't need external scope.
3288 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
3289 (many functions and arrays): Declare `const'.
3291 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
3293 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
3294 removing the declaration from m4.h. Also rename false to FALSE
3297 * lib/Makefile.in (Makefile): New goal.
3299 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
3300 so heavily loaded. It gets more easily overridable, calling make.
3301 Reported by Jim Meyering.
3303 * Makefile.in (dist): Get .fname from the current directory name,
3304 instead of from version.h. I need updating many files manually,
3305 when the version changes, version.h is just one of them.
3307 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
3309 * m4.h: Remove the tag `boolean' on the enum introducing typedef
3310 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
3311 Reported by Tom McConnell.
3313 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
3315 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
3316 39.cleardiv, which were describing missing or spurious newlines.
3317 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
3318 do not depend on machine word size, `/bin/false' implementation,
3319 or `wc' output format. `make check' is more dependable, now.
3321 * checks/check_them: Summarize the failed tests by listing their
3322 name, at end. If none, issue `All checks successful'. Output
3323 `Checking' instead of `Input file:'.
3325 * checks/get_them, checks/check_them: Reindented.
3327 * Makefile.in (dist): chmod a+r before making the tar file.
3329 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
3331 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
3333 * input.c (next_token): Reinitialize token_buttom just after using
3334 it as a watermark with obstack_free. Or else, a future token, big
3335 enough for triggering reallocation of the obstack chunk, could
3336 void the initialized value of token_buttom, later causing panic in
3337 obstack_free. Rename token_buttom to token_bottom everywhere.
3339 * m4.h: Before declaring errno, first include <errno.h> and
3340 ensure that it does not define errno.
3341 Reported by Richard Stallman.
3343 Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule)
3345 * builtin.c: Define and use DECLARE macro for builtins.
3347 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
3348 argument, this is a common idiom for introducing long comments.
3350 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
3351 arguments. The last argument was silently ignored.
3353 * m4.c (cmd_error): Add a missing semicolon before va_end().
3355 Tue Nov 10 08:57:05 1992 Francois Pinard (pinard at icule)
3357 * Makefile.in: Now handle protoized sources. Define and use U.
3358 Compile and use ansi2knr with old compilers. Update DISTFILES.
3359 Add `aclocal.m4' to `configure' dependencies.
3360 * ansi2knr.c: New, from Ghostscript distribution.
3361 * configure.in: Define U through FP_PROTOTYPES for old compilers.
3362 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
3363 * aclocal.m4: New, provide FP_PROTOTYPES.
3364 * m4.h: Conditionnaly protoized through Args, save for varags.
3365 * builtin.c: Protoized. Then:
3366 Include <sys/types.h> if size_t is not defined, before "regex.h".
3367 (m4_ifelse): Fetch built-in name properly for diagnostic.
3368 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
3369 (m4_regexp): Add const to `msg' declaration.
3370 (m4_patsubst): Add const to `msg' declaration.
3371 * debug.c: Protoized, save for varargs.
3372 * eval.c: Protoized.
3373 * format.c: Protoized.
3374 * input.c: Protoized.
3375 * m4.c: Protoized, save for varargs. Then:
3376 (xfree): Accept void * instead of char *.
3377 (xmalloc): Return void * instead of char *.
3378 (xrealloc): Accept and return void * instead of char *.
3379 * macro.c: Protoized.
3380 * output.c: Protoized.
3381 * path.c: Protoized. Then cast some (char *) over xmalloc's.
3382 * symtab.c: Protoized.
3384 Fri Nov 6 02:05:21 1992 Francois Pinard (pinard at icule)
3386 * m4.texinfo: Remove directory from diagnostics in 30.include,
3387 51.eval, 56.errprint and 57.m4exit tests.
3389 * m4.h: Remove declarations for int or void system functions, they
3390 cause more conflicting trouble than they make good.
3392 * configure.in: Avoid configuration header file. Add some tests.
3393 * m4.h: Remove #include "config.h".
3394 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
3395 Then, rewritten for better compliance with GNU standards.
3397 Thu Nov 5 12:37:13 1992 Francois Pinard (pinard at icule)
3399 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
3400 because of a misplaced #endif.
3402 * Many *.[hc] files: Correct intra-line spacing here and there,
3403 according to GNU indent 1.6 advice.
3405 * configure.in: New, using Autoconf 1.2.
3406 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.
3407 * Delete old configure.in, configure, etc/configure.in,
3408 etc/configure, lib/configure.in, lib/configure and config/*.
3409 Reported by Jason Merrill.

3416 * version.h: De-automatize, force value in.
3418 * m4.c: Changes in order to use a newer getopt.h.
3419 Reported by David MacKenzie.
3421 * checks/: New name for examples/.
3422 * checks/get_them: New location for etc/get_examples.
3423 * checks/check_them: New location for etc/check_examples.
3424 * Makefile.in, checks/get_them, checks/check_them: Adjust.

3426 * Delete empty etc/.
3427 * examples/: New name for test/.
3429 Tue Mar 10 00:29:46 1992 Francois Pinard (pinard at icule)
3431 * Makefile.in (check): Add m4 as dependency.
3433 * m4.c: Accept --no-warnings instead of --no_warnings, and
3434 --no-gnu-extensions instead of --no_gnu_extensions. Make the
3435 usage message more informative.
3436 Reported by David MacKenzie.

3452 Reported by Richard Stallman.
3454 * config/hmake-unicos, config/s-unicos.h: New files.
3455 Reported by Hal Peterson.
3457 * eval.c (exp_term): Have N^0 return 1.
3458 Reported by Michael Fetterman.
3460 * eval.c, input.c, m4.h: Remove last comma in enums.

3479 * The built-in format can now be configured to use sprintf as
3480 the formatting engine, for systems without [efg]cvt(3).
3482 * GNU library code is moved to the ./lib subdirectory; other
3483 utility files are now in ./etc.

3490 Francois Pinard and Roland H. Pesch for providing me with reports.
3492 * The builtins incr and decr are now implemented without use of
3495 * The builtin indir is added, to allow for indirect macro calls
3496 (allows use of "illegal" macro names).
3498 * The debugging and tracing facilities has been enhanced
3499 considerably. See the manual for details.
3501 * The -tMACRO option is added, marks MACRO for tracing as soon
3504 * Builtins are traced after renaming iff they were before.

3517 * A bug in dnl is fixed.
3519 * A bug in the multi-character quoting code is fixed.
3521 * Several typos in the manual has been corrected. More probably
