1641 `51 Franklin Street, Fifth Floor, MA 02110-1301'.
1643 Also, some of the files here were never updated from the previous
1644 '675 Mass Ave, Cambridge, MA 02139', so changed those to the

1665 (fetch): Get latest gendocs files.
1666 (web-manual): Rewritten to use gendoc for multiformat manuals.

1668 * doc/m4.texinfo (Index): HFS+ (the file system on my Mac) is case
1669 preserving, but case insensitive, so generating html docs per node
1670 clashes between Index.html, the node file, and index.html, the
1671 top-level of the document tree...
1672 (Index macro): ...so renamed to this. Changed all references.

1696 from removing it accidentally again.
1697 * checks/get-them: Allow for trailing spaces tucked behind
1700 2005-03-31 Eric Blake <ebb9@byu.net> (tiny change)

1729 on Windows, so that the frozen file reader will work.
1730 Reported by Josef T. Burger.
1732 * src/m4.c (main): Modernise the --version output.
1734 2005-02-03 Gary V. Vaughan <gary@gnu.org>
1736 Modernise the configury a little to prevent spurious errors from
1737 Autoconf-2.59's autoreconf:
1739 * config.h.in: Renamed to...
1740 * config-h.in: ...this to better support DOS 8.3 file systems.
1741 * acconfig.h: Removed.
1742 * configure.in: Renamed to...
1743 * configure.ac: ...this, and AC_DEFINE used to declare config.h
1744 entry comments. Slight reorganisation and reformatting.

1757 difference between PRODUCT="m4" and PACKAGE="GNU M4".
1758 * configure: Regenerated.
1760 2005-02-03 Noah Misch <noah@cs.caltech.edu>
1762 * src/output.c (mkstemp): Make non-static, and build regardless of
1763 HAVE_TMPFILE; src/builtin.c also needs this replacement.
1766 2004-09-09 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
1768 * configure.in (AC_CHECK_HEADERS): Commit works best when you save
1769 changes from your editor buffer first.
1771 * configure.in (AC_CHECK_HEADERS): Add signal.h, sys/signal.h.
1772 * src/m4.c: And include them as appropriate.
1775 2004-09-09 Andreas Schwab <schwab@suse.de>

1801 * src/output.c (insert_file): Don't assume errno has a valid
1802 value simply because fread returns zero. This fixes a
1803 portability bug reported by Marion Hakanson in
1804 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.

1881 * src/macro.c (collect_arguments): Cast obstack arguments to
1882 (voidstar), so avoiding compiler warnings.
1883 Reported by Joseph E. Sacco.

1923 ANSI2KNR, depending on the fact the compiler is ANSI or not.
1924 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
1925 Remove the sed filter after ansi2knr for debug.c. Use $O instead
1926 of $U, put underline in extensions rather than in basenames. Use
1927 implicit rules, now that regularity makes this possible.
1928 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
1929 of ansi2knr whenever it is needed.
1930 * configure.in: Adjusted for correct STACKOVF substitution.
1931 * src/debug.c (trace_format): When not __STDC__, use (...) as a

1948 Reported by Jim Kingdon.
1950 * {,/*}Makefile.in: Use && after all cd, in case they fail.
1952 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.

2012 * Makefile.in: Make TAGS in lib also, not just in src.
2013 Reported by Karl Berry.
2015 * Makefile.in (distclean, realclean): Instead of recursively
2016 calling $(MAKE) for the -local part, allow parallel execution of
2017 -recursive and -local, only delay the removal of config.status,
2018 which is repeated in both goals.
2020 Tue Sep 13 19:21:05 1994 Francois Pinard (pinard@icule)
2024 * Makefile.in: Group all *clean-recursive goals in one, using sed

2030 Reported by Kaveh R. Ghazi.
2032 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
2033 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
2036 * configure.in: Use date instead of touch for stamp-h.
2037 * Makefile.in (stamp-h.in): Idem.
2039 * Makefile.in (distclean, realclean): Force serial execution of

2087 * Makefile.in (distclean-local): Delete config.log.
2088 Reported by Jim Meyering.

2092 calling a function by that name. Declare the variable.
2093 * src/m4.h: Adjust declaration for prefix_all_buitins.
2094 * src/builtin.c (builtin_init): Merge in functionality from
2095 previous prefix_all_buitins function, while making entries in the
2096 symbol table, but not modifying the builtin description itself.
2098 * src/freeze.c (reload_frozen_state): Add a useless `break;',
2099 because *many* compilers do not accept an empty `default:'.

2129 beginning for the eventual withdrawal of NUL terminated strings.)
2130 * output.c (shipout_text): Accept a length parameter, and use it.
2131 All callers adjusted.
2133 Mon Aug 29 12:27:19 1994 Francois Pinard (pinard@icule)
2135 * m4.h: Include <unistd.h> if it exists.
2136 * stackovf.c: Don't.
2138 Clean up for current_diversion variable:
2139 * output.c: Move current_diversion from builtin.c.
2140 * m4.h: Declare current_diversion so builtin.c can access it.
2141 * output.c (output_init, make_diversion): Initialize or update
2143 * builtin.c (builtin_init, m4_divert): Leave current_diversion
2146 Remove limit on number of diversions:
2147 * output.c: Replace ndiversion by diversions, declare it.
2148 (output_init): Allocate only diversion 0.
2149 (make_diversion): Allocate new diversions as needed.
2150 * m4.h, m4.c: Remove NDIVERSIONS and ndiversion related stuff.
2151 * m4.c: Still accept -N, but do nothing with it.
2152 Reported by David MacKenzie.
2155 * output.c (freeze_diversions): New function.
2156 * m4.h: Declare freeze_diversions.
2157 * freeze.c: Document frozen file format, revise it, call
2158 freeze_diversions to add diversions to frozen format, and code to
2159 reload them properly.
2160 * m4.c: Do not undivert automatically at end when status being
2161 frozen. Do not call builtin_init when reloading frozen state.
2163 Speed up diversion processing:
2164 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
2165 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
2166 structure and variables, cached variables out of output_diversion,
2167 reallocate_diversion_for and OUTPUT_CHARACTER.
2168 (shipout_text, make_diversion, insert_diversion): Adapted to new
2170 (insert_file): Use better buffering.
2171 Reported by David MacKenzie.
2173 Sun Aug 28 05:20:02 1994 Francois Pinard (pinard@icule)
2175 * Makefile.in, lib/Makefile.in, checks/Makefile.in: Arrange so
2176 dist works from another build directory.
2178 Sat Aug 27 14:32:45 1994 Francois Pinard (pinard@icule)
2180 * symtab.c (hack_all_symbols): Use hash_table_size instead of
2181 constant HASHMAX, for -H option to work better.
2183 * builtin.c (DECLARE): Simplify by using _ ().
2185 * freeze.c: New file.
2186 * Makefile.in: Compile it, distribute it.
2187 * m4.c: Recognize, document and process --freeze-state (-F) and
2188 --reload-state (-R) options. Pass a true flag to builtin_init
2189 only if no reloading some state.
2190 * builtin.c (define_builtin): Remove static specifier.
2191 (find_builtin_by_name): Remove static specifier.
2192 (builtin_init): Accept and obey a flag argument.

2204 Mon Aug 15 12:38:05 1994 Francois Pinard (pinard@icule)
2206 * m4.c (long_options): Use "error-output", the dash was missing.
2207 Reported by Akiko Matsushita.
2209 Fri Aug 12 16:38:01 1994 Francois Pinard (pinard@icule)
2211 * m4.h: Include <sys/types.h>.
2212 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
2213 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
2215 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
2217 * builtin.c (dump_args): Declare len as size_t, not int.
2219 * debug.c: Prototype the forward declaration of debug_set_file.
2221 * builtin.c (m4_undivert): Replace div by file, for avoiding the
2222 shadowing of this variable.
2223 * output.c (insert_diversion): Idem.
2225 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
2226 (input_init): Duplicate default quote and comment strings.
2227 (set_quotes): Free previous quote strings in all cases. Duplicate
2228 even default quote strings.
2229 (set_comment): Free previous comment strings in all cases.
2230 Duplicate even default comment strings.

2233 * Makefile.in (distclean-local): Also delete config.cache.
2235 * m4.c (usage): Reorganize the --help output by topic. Include a
2236 description for debugging flags.
2238 Fri Jul 29 10:15:52 1994 Francois Pinard (pinard@icule)
2240 * configure.in: If sigaction is available and SA_ONSTACK defined,
2241 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
2242 defined, use sigvec. Else don't compile stackovf.c.
2243 * stackovf.c (setup_stackovf_trap): Idem.
2244 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
2247 Thu Jul 21 22:43:17 1994 Francois Pinard (pinard@icule)
2249 * m4.c (usage): Replace printf par fputs.
2251 Mon Jul 18 23:48:23 1994 Francois Pinard (pinard@icule)
2255 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
2257 * configure.in: Check for sigaction and sigvec. Add a new delayed
2258 check for RLIMIT_STACK, combine in the checking for getrlimit.
2259 All those things are not universally available.
2260 * stackovf.c: Split setting up the trap handler and catching
2261 signals, for better taking care of various configure outcomes.
2262 * examples/stackovf.sh: Correct a typo.
2263 Reported by Eric Backus, Jim Avera and Jim Meyering.
2265 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)
2267 * ansi2knr.c: New version sent by its author, Peter Deutsch.
2269 Fri Jul 15 14:36:21 1994 Francois Pinard (pinard@icule)
2271 * Makefile.in: Modify so parallel make will not try making
2272 lib/libm4.a twice simultaneously.
2273 Reported by Jim Meyering.
2275 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
2277 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
2278 error message, for when no code possibility exists. Even if this
2279 line is completely #ifdef'ed out, it brings a syntax error.
2280 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
2282 * Makefile.in (install): Have install depend on all too, for lib
2283 to be remade as needed.
2285 * examples/stackovf.sh: Try ksh, bsh and bash for shells
2286 providing ulimit, instead of using only ksh.
2287 Reported by Jim Avera and Joseph E. Sacco.
2289 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
2291 * Makefile.in (check): Have it depend on all instead of m4. In
2292 this way, a change in lib will be detected and processed.
2294 * builtin.c (numeric_arg): Use strtol and verify the conversion,
2295 instead of using sscanf which stops as soon as there is a
2296 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
2297 and divert(1xyzzy) were all accepted without any warning or error
2299 * m4.h: Declare strtol as long if not including stdlib.h.
2300 * configure.in: Check for limits.h, and replace strtol if missing.
2301 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
2302 * lib/strtol.c: New file, from elsewhere.
2303 Reported by Andreas Schwab.
2305 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
2307 * macro.c (expand_macro): Cast value to (boolean) prior to
2308 assigning it to traced.
2309 Reported by Tom McConnell.
2311 * Makefile.in (m4): Always make all in lib first.
2312 Reported by Jim Meyering.
2314 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
2316 * stackovf.c: Isolated OS-dependent sections; Improved portability,
2317 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
2318 handlers), and a default error message if the fault address is not
2319 available (when neither siginfo.h nor BSD sigcontext are supported).
2320 * configure.in: Changes for stackovf.h: Check for sigcontext,
2321 sigaction, sigstack, and define rlim_t as int if necessary.
2322 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
2323 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
2324 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
2326 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
2328 * configure.in: Use AC_SET_MAKE.
2329 * Makefile.in: Use @SET_MAKE@.
2330 Reported by Jim Meyering.
2332 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
2333 Reported by Ian Taylor.
2335 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
2337 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
2338 because siginfo.h is unrelated to standard headers, and siginfo.h
2339 is already checked for.
2340 Reported by Joseph E. Sacco.
2342 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
2344 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
2347 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
2349 * builtin.c (substitute): Use \& to represent this part of the
2350 string which was matched by the whole regexp, instead of
2351 representing the whole string. Any usage of \0 issues a warning
2352 and acts like \&, it will disappear in some subsequent release.
2354 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
2356 * m4.c: Complete prototype for forwarded declaration of usage.
2358 * input.c (init_macro_token): Correct own reference in error
2359 message. Previous name get_macro_func was referred to instead.
2360 (next_char): Correct own reference in error message. Previous
2361 name advance_input was referred to instead.
2363 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
2364 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
2365 and_term, not_term, logical_not_term, cmp_term, shift_term,
2366 add_term, mult_term, exp_term, unary_term, simple_term): Add
2367 prototype to forwarded declarations. Declare parameter v1 as
2368 eval_t * instead of int *. Same for local variable v2 in dyadic
2369 functions. Same for result in exp_term.
2370 * builtin.c (m4_eval): Declare value as eval_t instead of int.
2371 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
2372 unsigned_eval_t instead of unsigned int. Change casts accordingly.
2373 (shipout_int): Cast first argument of ntoa to eval_t.
2374 Reported by Thorsten Ohl.
2376 * macro.c: Complete the prototypes of forwarded expand_macro and
2378 Reported by Thorsten Ohl.
2380 * m4.h: Define voidstar as void * or char * depending on __STDC__.
2381 The Ultrix 3.1 compiler cannot do much with void pointers.
2383 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
2384 * m4.c (xfree): Replace void * by voidstar.
2385 Reported by Tom McConnell.
2387 * ansi2knr.1: New, from elsewhere.
2388 * Makefile.in (DISTFILES): Distribute ansi2knr.1
2390 * Makefile.in (stamp-h.in): Avoid running ./config.status if
2391 stamp-h does not exist yet. This avoids running it a second time
2392 just after the initial ./configure.
2393 Reported by David MacKenzie and Tom McConnell.
2395 * m4.h: Replace the enum debug_info declaration with a series of
2396 #define's. The Ultrix 3.1 compiler would otherwise need casting
2397 (int) to most references, when used in expressions.
2398 Reported by Tom McConnell.
2400 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
2402 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
2403 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
2404 calls the compiler. Previously, FP_PROTOTYPES was only calling
2405 the preprocessor; by not being subject to CFLAGS, this was
2406 discouraging those flags asking for ANSI compilation.
2407 * acconfig.h: Document HAVE_PROTOTYPES.
2408 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
2409 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
2410 Reported by Eric Backus.
2412 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
2413 from the environment. Default CFLAGS to -g if not set.
2414 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
2415 * lib/Makefile.in: Have CFLAGS substituted from configure.
2416 Reported by Eric Backus and Tom McConnell.
2418 * configure.in: m4_undefine changeword before using AC_ENABLE.
2420 * m4.h: Declare prototypes for error (for ANSI compilers only),
2421 prefix_all_builtins and reference_error.
2422 Reported by Tom McConnell.
2424 * input.c (set_word_regexp): Do not try to initialize the array
2425 test from a string, this does not work with non-ANSI compilers.
2426 Reported by Eric Backus.
2428 * Makefile.in (dist): Clean examples/ before saving it.
2429 (distclean-local): Also remove stamp-h.
2430 Reported by Eric Backus.
2432 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
2434 Reported by Tom McConnell.
2436 * checks/Makefile.in (clean): Depends on mostlyclean.
2437 (mostlyclean): New goal.
2439 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
2441 * Makefile.in (DISTFILES): Distribute install.sh.
2442 * install.sh: New file, copied from elsewhere.
2443 Reported by Assar Westerlund and Kaveh R. Ghazi.
2445 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
2447 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
2448 * acconfig.h: Explain ENABLE_CHANGEWORD.
2450 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
2451 from code provided by Pete Chown]
2452 * m4.h: Add original_text field to u_t variant of union u.
2453 Declare TOKEN_DATA_FUNC macro.
2454 * builtin.c: Declare changeword.
2455 (m4_changeword): New function.
2456 * input.c: Include "regex.h", define variables with word regexps.
2457 (input_init): Initialize the word regexp.
2458 (set_word_regexp): New.
2459 (next_token): Declare local variables, use the previous code if
2460 default_word_regexp is true. Else, match using a new code. Save
2462 * macro.c (expand_token): Ship out original text if not a macro
2464 Reported by Krste Asanovic and Pete Chown.
2466 [These modifs all depend upon ENABLE_CHANGEWORD]
2467 * m4.h: Declare external user_word_regexp.
2468 * m4.c: Declare user_word_regexp, and initialize it from
2469 --word-regexp or -W, or NULL if not specified.
2470 * input.c: Use user_word_regexp if specified, instead of
2471 DEFAULT_WORD_REGEXP.
2473 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
2476 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
2477 * checks/Makefile.in: Empty the suffix list.
2478 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
2480 * m4.c: Declare nesting_limit and initialize it to 250.
2481 Implement -LNUMBER or --nesting-limit=NUMBER to change its
2483 * m4.h: Declare nesting_limit as external.
2484 * macro.c (expand_macro): Stop execution whenever nesting limit
2486 Reported by Bengt Mertensson.
2488 * eval.c (evaluate): Diagnose excess characters in eval input.
2489 Things like `eval(08)' used to return 0 with no diagnostic.
2491 * m4.h: Capitalize first letter of all macro arguments in
2494 * m4.c: Declare warning_status, initialize it to 0. Add new
2495 option -E, or --fatal-warnings, which sets warning_status to
2496 EXIT_FAILURE instead.
2497 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
2498 EXIT_FAILURE if not otherwise done by header files.
2499 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
2500 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
2501 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
2502 argument of all M4ERROR calls.
2503 Reported by Noah Friedman.
2505 * examples/incl-test.m4: Renamed from incl_test.m4.
2506 * examples/include.m4: Include incl-test.m4 instead of
2508 * examples/multiquotes.m4: Renamed from multi-quotes.m.
2510 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
2512 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
2513 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
2514 also tested it on a Sun Sparc workstation running SunOS 4.x.
2516 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
2517 49.format check, abusing a `union values' argument with sprintf
2518 without selecting the proper field. Now, save the formatting type
2519 first, delaying the fetch of the corresponding argument.
2520 Reported by Joseph E. Sacco and Tom Quinn.
2522 * format.c (format): Remove const from char *fmt declaration when
2523 not HAVE_EFGCVT, because a NUL may be forced into it.
2525 * m4.h: Declare atof() when not STDC_HEADERS.
2526 Reported by Joseph E. Sacco.
2528 * Regenerate configure using Autoconf 1.11, this corrects a
2529 problem about an incorrect cpp seting on NeXT 3.1.
2530 Reported by Alexander Lehmann.
2532 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
2534 * m4.h (_): Change argument from `x' to `Args'.
2536 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
2538 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
2539 bringing more evil than good on a few systems.
2540 Reported by Greg A. Woods.
2542 Fri Apr 22 15:59:35 1994 Francois Pinard (pinard@icule)
2544 * m4.h: Rename Args() to _().
2545 * m4.h: Remove extern specifier from all function declarations.
2547 Fri Apr 22 15:51:21 1994 Jim Avera (jima@netcom.com)
2549 * stackovf.c: New file implementing stack-overflow detection.
2550 * configure.in: Check for getrlimit, sigaction. If all of
2551 standard headers, getrlimit and sigaction, define USE_STACKOVF and
2552 substitute ${U}stackovf.o for STACKOVF.
2553 * acconfig.h: Declare USE_STACKOVF.
2554 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
2555 * m4.h: Declare setup_stackovf_trap().
2556 * m4.c: Call setup_stackovf_trap().
2557 * tests/stackovf_test.sh: New file.
2559 Wed Apr 13 14:10:30 1994 Francois Pinard (pinard@icule)
2561 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
2563 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
2565 Sun Jan 30 14:24:19 1994 (pinard at icule)
2567 * m4.h: Remove definition of volatile, not used anymore.
2568 Reported by Jim Meyering and Joseph E. Sacco.
2570 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
2571 of `if ... else /* nothing */' for if macros.
2572 Reported by Jim Meyering.
2574 * builtin.c (m4_regexp): Reorganize the code for avoiding a
2575 warning from gcc about `repl' possibly used before defined.
2576 Reported by Jim Meyering.
2578 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
2579 Reported by Jim Meyering.
2581 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
2583 * m4.h: Move the conditional definition of volatile after the
2584 inclusion of system files, because they may define it first.
2586 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
2588 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
2589 get around a problem with Alpha make seeing a syntax error, there.
2590 Reported by Vern Paxson.
2592 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
2594 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
2595 Reported by Richard Stallman.
2597 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)
2599 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
2600 instead of AC_HAVE_FUNCS.
2601 Reported by Noah Friedman.
2603 Wed Dec 1 09:37:53 1993 Francois Pinard (pinard@icule)
2605 * m4.c: Initialize show_help and show_version to zero.
2607 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
2608 Use them in exit() and usage() calls.
2610 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
2612 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
2613 syserr() macro. Delete errref, add reference_error and M4ERROR.
2614 * m4.c: Replace errref, which was returning an input reference
2615 string, with reference_error, which prints it on standard error.
2616 * builtin.c, output.c: Use errno as second parameter to error,
2617 instead of using syserr() with %s.
2618 * *.c: Use M4ERROR instead of error: no more errref() with %s.
2619 Doing so, the program name appears after the input reference
2620 instead of before, which eases M-x next-error processing.
2622 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
2624 * checks/get-them: Escape braces with backslashes in patterns,
2625 because HPUX-9.01 awk needs this.
2626 Reported by Jim Meyering.
2628 Mon Nov 22 10:55:52 1993 Francois Pinard (pinard@icule)
2630 * builtin.c: Declare "FILE *popen ();".
2632 * m4.h: Remove MESSAGE{,1,2}, WARNING1, FATAL{,1}, INTERNAL_ERROR
2633 macros, replace error_message_prefix() declaration by errref()'s.
2634 Declare xrealloc, for use in errref().
2635 * m4.c: Delete error_message_prefix() function, add errref().
2636 * *.c: Use error() systematically in place of all error macros,
2637 now that error() flushes stdout first. Make needed adjustments.
2639 * m4.h: Remove const in sys_errlist[] declaration, it creates
2640 conflicts on SGI and Alpha.
2641 Reported by Kaveh R. Ghazi.

2659 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
2661 * input.c (input_init): Initialize quote and comment strings
2662 explicitely instead of calling set_quotes and set_comment: by

2666 expected is on the left and the obtained on the right.
2668 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR

2718 Reported by Joel Sherrill.
2720 * builtin.c (prefix_all_builtins): Instead of the table size, use
2721 the null entry at end for stopping the loop. It was overwritten.
2722 Reported by Andreas Schwab and Jim Meyering.
2724 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
2725 Reported by Kaveh R. Ghazi.

2754 * checks/check-them: Identify the m4 version being checked. For
2755 finding m4, look in $PATH instead of in the parent directory.
2756 * Makefile.in (check): Prepend `pwd` to $PATH before checking.
2757 * checks/Makefile.in (.all-stamp): Always create check files in
2758 the source hierarchy, not anymore in the build hierarchy.

2979 This is still a beta release for the future GNU m4 version 1.1.
2981 * lib/alloca.c: New, from elsewhere.
2982 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
2984 * m4.h: Do not define index/rindex if already defined. If
2985 FALSE/TRUE are already defined, do not redefine them, but merely
2986 define boolean typedef to int.
2988 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
2989 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
2990 because some C compilers do not like connectives with #ifdef.
2991 * m4.h: Define `volatile' only if __GNUC__, instead of once for
2992 __GNUC__ and once for __STDC__.
2993 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
2995 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
2996 Makefile dependencies. Without it, make keeps destroying and
2997 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
2999 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
3000 to diversion/DIVERSION, this was a spelling error.
3002 * m4.c: Declare version[], remove #include "version.h".
3003 * version.h: Deleted.
3004 * Makefile.in: Remove references to version.h.
3006 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
3007 production, by using a simpler and more robust algorithm. This
3008 solves the problem of synclines sometimes written in the middle of
3009 an output line. Delete sync_line() and output_lines variable.
3010 * m4.h: Remove sync_line prototype and output_lines declaration.
3011 * input.c (next_char), output.c (shipout_text): Remove references
3013 * input.c (push_file, pop_file): Merely put the value -1 in
3014 output_current_line instead of calling sync_line, for delaying a
3015 single `#line NUM FILE' before next output line. Do not test
3016 for sync_output, because this is unnecessary clutter.
3017 * output.c (make_divertion, insert_divertion): Idem.
3018 * input.c: Rename must_advance_line to start_of_input_line, for
3021 * debug.c (trace_header): Select a new debug line format, which
3022 better complies with GNU standards for formatting error messages.
3023 With option `-dfl', M-x next-error might be used on the output.
3024 * m4.c (vmesg): Adjust format of error output to GNU standards.
3025 * m4.texinfo: Adjust examples for `make check' to work.
3027 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
3028 case for enum debug_info constants, which were all lower case.
3030 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
3032 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
3033 collected patches. I tried a few times using newer regex.[ch], it
3034 mysteriously stopped aborting with this one. Insecure feeling...
3035 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
3037 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
3039 * m4.c: Change `--no-warnings' to `--silent'.
3040 Reported by David MacKenzie.
3042 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
3043 leave it off for now. See comment in m4.c for justification.
3044 Reported by David MacKenzie.
3046 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
3047 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
3049 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
3051 * Makefile.in: Ensure recursive cleaning is done before local
3052 cleaning for all clean goals.
3054 * builtin.c (ntoa): Ensure the value is always interpreted as a
3055 signed quantity, whatever the radix is.
3057 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
3059 * builtin.c, format.c, input.c: Split long lines.
3060 * m4.c: Use typedef macro_definition instead of struct
3062 * symtab.c: Use typedef symbol instead of struct symbol.
3064 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
3066 * *.[ch]: Remove all trailing whitespace, in code and comments.
3068 * configure.in: Find some awk.
3069 * Makefile.in: Add $(AWK) to MDEFINES.
3070 * checks/Makefile.in: Transmit $(AWK) to get_them.
3071 * checks/get_them: Use $AWK instead of gawk. Add a close in the
3072 awk script when switching files, because without this, mawk runs
3073 out of file descriptors.
3075 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
3077 * Makefile.in (realclean): Delete m4.info*.
3078 Reported by Jim Meyering.
3080 * Makefile.in: Adjust and link with checks/Makefile.
3081 * checks/Makefile.in: New.
3082 * configure.in: Output checks/Makefile.
3084 * checks/get_them: Have the dnl header of each test more
3085 recognizable by next-error, also use a better message.
3087 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
3089 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
3090 And use that only if __GNUC__ since we're using it's GCC-specific
3091 semantics that tell the compiler the associated function doesn't
3094 * builtin.c (substitute): Don't use character as an array index.
3095 (dumpdef_cmp): Make formal arguments `const void *' to avoid
3096 warnings with gcc -W -Wall on systems with qsort prototype.
3097 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
3100 * eval.c (most functions): Add parentheses to assignments used
3101 as truth values go avoid warnings from gcc -Wall.
3103 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
3104 any functions that don't need external scope.
3106 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
3107 (many functions and arrays): Declare `const'.
3109 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
3111 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
3112 removing the declaration from m4.h. Also rename false to FALSE
3115 * lib/Makefile.in (Makefile): New goal.
3117 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
3118 so heavily loaded. It gets more easily overridable, calling make.
3119 Reported by Jim Meyering.
3121 * Makefile.in (dist): Get .fname from the current directory name,
3122 instead of from version.h. I need updating many files manually,
3123 when the version changes, version.h is just one of them.
3125 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
3127 * m4.h: Remove the tag `boolean' on the enum introducing typedef
3128 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
3129 Reported by Tom McConnell.
3131 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
3133 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
3134 39.cleardiv, which were describing missing or spurious newlines.
3135 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
3136 do not depend on machine word size, `/bin/false' implementation,
3137 or `wc' output format. `make check' is more dependable, now.
3139 * checks/check_them: Summarize the failed tests by listing their
3140 name, at end. If none, issue `All checks successful'. Output
3141 `Checking' instead of `Input file:'.
3143 * checks/get_them, checks/check_them: Reindented.
3145 * Makefile.in (dist): chmod a+r before making the tar file.

3149 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
3151 * input.c (next_token): Reinitialize token_buttom just after using
3152 it as a watermark with obstack_free. Or else, a future token, big
3153 enough for triggering reallocation of the obstack chunk, could
3154 void the initialized value of token_buttom, later causing panic in
3155 obstack_free. Rename token_buttom to token_bottom everywhere.
3157 * m4.h: Before declaring errno, first include <errno.h> and
3158 ensure that it does not define errno.
