1575 Also, some of the files here were never updated from the previous
1576 '675 Mass Ave, Cambridge, MA 02139', so changed those to the
1577 '51 Franklin Street, Fifth Floor, MA 02110-1301' address too.
1579 2005-03-31 Mike Frysinger <vapier@gentoo.org>

1591 * Makefile.in (dist): Make .tar.bz2 tarball too.
1592 * Makefile.maint (TSDEPS_DIST): Remove m4/libtool.m4.
1593 (cvs-news): Look 1 line further down for NEWS release number.
1594 (cvs-dist): We don't use automake, so make dist is fine.
1595 Remove double . before suffixes.
1596 (cvs-release): Don't mention manual.html.
1597 (fetch): Get latest gendocs files.
1598 (web-manual): Rewritten to use gendoc for multiformat manuals.

1600 * doc/m4.texinfo (Index): HFS+ (the file system on my Mac) is case
1601 preserving, but case insensitive, so generating html docs per node
1602 clashes between Index.html, the node file, and index.html, the
1603 top-level of the document tree...
1604 (Index macro): ...so renamed to this. Changed all references.
1606 2005-03-31 Gary V. Vaughan <gary@gnu.org> (tiny change)

1626 * doc/m4.texinfo (Patsubst): Re-add trailing space required by
1627 checks/47.patsubst, with a redundant @comment to prevent emacs
1628 from removing it accidentally again.
1629 * checks/get-them: Allow for trailing spaces tucked behind
1630 @comment marks.

1640 on Cygwin.
1641 Reported by Eric Blake.
1643 2005-02-04 Gary V. Vaughan <gary@gnu.org>
1645 * lib/regex.c, lib/regex.h: Updated from gnulib.

1659 recognition macros.
1660 * src/freeze.c (produce_frozen_state): Use \n line-endings even
1661 on Windows, so that the frozen file reader will work.
1662 Reported by Josef T. Burger.
1664 * src/m4.c (main): Modernise the --version output.
1666 2005-02-03 Gary V. Vaughan <gary@gnu.org>
1668 Modernise the configury a little to prevent spurious errors from
1669 Autoconf-2.59's autoreconf:
1671 * config.h.in: Renamed to...
1672 * config-h.in: ...this to better support DOS 8.3 file systems.
1673 * acconfig.h: Removed.
1674 * configure.in: Renamed to...
1675 * configure.ac: ...this, and AC_DEFINE used to declare config.h
1676 entry comments. Slight reorganisation and reformatting.
1677 * aclocal.m4: Use third argument to AC_DEFINE to declare config.h
1678 entry comments.
1679 (AC_INIT): Use a modern 3 argument call.

1682 s/PRODUCT/PACKAGE/g.
1683 * Makefile.in (DISTFILES): Removed acconfig.h, configure.in,
1684 config.h.in. Added configure.ac, config-h.in.
1685 (stamp-h.in): Removed acconfig.h from dependencies.
1686 (configure): Depends on configure.ac, not configure.in.
1687 * doc/Makefile.in (stamp-vti): Ditto.
1688 * src/freeze.c (produce_frozen_state), src/m4.c (main): Adjust for
1689 difference between PRODUCT="m4" and PACKAGE="GNU M4".
1690 * configure: Regenerated.
1692 2005-02-03 Noah Misch <noah@cs.caltech.edu>
1694 * src/output.c (mkstemp): Make non-static, and build regardless of
1695 HAVE_TMPFILE; src/builtin.c also needs this replacement.
1696 * NEWS: Update.
1698 2004-09-09 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
1700 * configure.in (AC_CHECK_HEADERS): Commit works best when you save

1728 relies on this.
1729 * src/builtin.c (m4_esyscmd): Clear errno before calling popen.
1730 (m4_maketemp): Clear errno before calling mkstemp.
1731 * src/path.c (path_search): Don't let "free" trash errno when
1732 returning NULL.
1733 * src/output.c (insert_file): Don't assume errno has a valid
1734 value simply because fread returns zero. This fixes a
1735 portability bug reported by Marion Hakanson in
1736 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.

1754 to pacify Texinfo 4.7.
1755 * doc/Makefile.in (info): Remove info-1, info-2, info-3.
1757 * src/m4.h, src/debug.c: Use #ifdef __STDC__, not #if __STDC__, to

1783 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
1784 empty file rather than to a nonexistent file. This closes a common
1785 security hole.
1786 * src/builtin.c (m4_maketemp): Implement the above, by using
1787 mkstemp rather than mktemp. (trivial change)
1789 2000-01-09 Akim Demaille <demaille@inf.enst.fr>
1791 * src/builtin.c (expand_ranges): Added break after trailing dash.

1808 ANSIfying compiler flags, this is of no use to check it before.
1809 Reported by Alexander Lehmann.
1811 Tue Nov 1 22:02:37 1994 Francois Pinard (pinard@icule)
1813 * src/macro.c (collect_arguments): Cast obstack arguments to
1814 (voidstar), so avoiding compiler warnings.
1815 Reported by Joseph E. Sacco.
1817 * src/freeze.c (produce_frozen_state): Cast printed lengths to
1818 (int) so they correspond to %d format items.
1819 Reported by Joseph E. Sacco.
1821 * src/m4.c (main): Cast the argument to xfree to (voidstar).
1822 * src/symtab.c (free_symbol): Idem.

1836 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
1837 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
1838 defines __STDC__ to 0, for indicating it is *not* ANSI!
1839 Reported by Kaveh R. Ghazi.
1841 * configure.in: Added obsolescent tests for AIX and Minix.
1843 * doc/Makefile.in (mostlyclean): Remove texclean in dependencies,
1844 which texclean does not exist anymore.
1845 Reported by Eric Backus, Jim Meyering, John David Anglin and
1846 Joseph E. Sacco.

1856 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
1857 Remove the sed filter after ansi2knr for debug.c. Use $O instead
1858 of $U, put underline in extensions rather than in basenames. Use
1859 implicit rules, now that regularity makes this possible.
1860 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
1861 of ansi2knr whenever it is needed.
1862 * configure.in: Adjusted for correct STACKOVF substitution.
1863 * src/debug.c (trace_format): When not __STDC__, use (...) as a
1864 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.

1867 * Makefile.in: Remove binprefix. Use transform_name instead.
1868 Reported by David MacKenzie.

1880 Reported by Jim Kingdon.
1882 * {,/*}Makefile.in: Use && after all cd, in case they fail.
1884 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.

1906 Sat Oct 1 11:22:42 1994 Francois Pinard (pinard@icule)
1908 * configure.in: Do not add -O to CFLAGS for GNU C, now that

1910 Reported by Jim Meyering.
1912 Fri Sep 23 08:16:58 1994 Francois Pinard (pinard@icule)
1914 * src/stackovf.c: Declare the handler_t typedef earlier in the
1915 code, use it for stackovf_handler.
1916 (setup_stackovf_trap): Use RETSIGTYPE instead of void while
1917 casting sigsegv_handler.
1918 Reported by Robert Bernstein.
1920 * src/m4.c (main): Initialize program_name to argv[0] without
1921 basename'ing it.
1922 Reported by Karl Berry.

1941 * lib/Makefile.in (DISTFILES): Distribute TAGS.
1942 (distclean): Do not remove TAGS.
1943 (realclean): Remove it.
1944 * Makefile.in: Make TAGS in lib also, not just in src.
1945 Reported by Karl Berry.
1947 * Makefile.in (distclean, realclean): Instead of recursively
1948 calling $(MAKE) for the -local part, allow parallel execution of
1949 -recursive and -local, only delay the removal of config.status,
1950 which is repeated in both goals.
1951 \f
1952 Tue Sep 13 19:21:05 1994 Francois Pinard (pinard@icule)
1954 * Release 1.3.
1956 * Makefile.in: Group all *clean-recursive goals in one, using sed
1957 to remove `-recursive' while calling make recursively. Also, use
1958 a subshell for each recursive $(MAKE).
1959 Reported by Jim Meyering.
1961 * src/m4.h (memcpy): Define with bcopy for BSD systems.
1962 Reported by Kaveh R. Ghazi.
1964 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
1965 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
1966 specify it.
1968 * configure.in: Use date instead of touch for stamp-h.
1969 * Makefile.in (stamp-h.in): Idem.
1971 * Makefile.in (distclean, realclean): Force serial execution of

2005 Pyramid 9820 OSx 5.0d).
2006 Reported by Kaveh R. Ghazi.
2008 * src/Makefile.in (TAGS): Remote -t from etags call.
2010 Fri Sep 2 10:37:10 1994 Francois Pinard (pinard@icule)

2031 because *many* compilers do not accept an empty `default:'.
2032 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
2033 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
2035 * configure.in: Use AC_TYPE_SIGNAL.
2036 * src/stackovf.c (setup_stackovf_trap): Use RETSIGTYPE.
2037 Reported by Robert Bernstein.
2039 * checks/Makefile.in (check): Modify PATH so check-them will find
2040 m4 in the src directory.
2041 * Makefile.in (check): Don't.
2042 Reported by Akiko Matsushita and Jim Meyering.

2055 files.
2056 * Makefile.in: Adjusted.
2057 * configure.in: Configure new Makefiles.
2059 * m4.h: Declare STRING typedef. Use it for comment and quote
2060 strings, adjusting all references. (This is the rudiments of a
2061 beginning for the eventual withdrawal of NUL terminated strings.)
2062 * output.c (shipout_text): Accept a length parameter, and use it.
2063 All callers adjusted.
2065 Mon Aug 29 12:27:19 1994 Francois Pinard (pinard@icule)
2067 * m4.h: Include <unistd.h> if it exists.
2068 * stackovf.c: Don't.

2081 (make_diversion): Allocate new diversions as needed.
2082 * m4.h, m4.c: Remove NDIVERSIONS and ndiversion related stuff.
2083 * m4.c: Still accept -N, but do nothing with it.
2084 Reported by David MacKenzie.
2086 Freeze diversions:
2087 * output.c (freeze_diversions): New function.
2088 * m4.h: Declare freeze_diversions.
2089 * freeze.c: Document frozen file format, revise it, call
2090 freeze_diversions to add diversions to frozen format, and code to
2091 reload them properly.
2092 * m4.c: Do not undivert automatically at end when status being
2093 frozen. Do not call builtin_init when reloading frozen state.
2095 Speed up diversion processing:
2096 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
2097 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
2098 structure and variables, cached variables out of output_diversion,
2099 reallocate_diversion_for and OUTPUT_CHARACTER.
2100 (shipout_text, make_diversion, insert_diversion): Adapted to new
2101 structures.
2102 (insert_file): Use better buffering.
2103 Reported by David MacKenzie.

2107 * Makefile.in, lib/Makefile.in, checks/Makefile.in: Arrange so
2108 dist works from another build directory.
2110 Sat Aug 27 14:32:45 1994 Francois Pinard (pinard@icule)
2112 * symtab.c (hack_all_symbols): Use hash_table_size instead of
2113 constant HASHMAX, for -H option to work better.
2115 * builtin.c (DECLARE): Simplify by using _ ().
2117 * freeze.c: New file.
2118 * Makefile.in: Compile it, distribute it.
2119 * m4.c: Recognize, document and process --freeze-state (-F) and
2120 --reload-state (-R) options. Pass a true flag to builtin_init
2121 only if no reloading some state.

2139 Reported by Akiko Matsushita.
2141 Fri Aug 12 16:38:01 1994 Francois Pinard (pinard@icule)
2143 * m4.h: Include <sys/types.h>.
2144 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
2145 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
2146 int.
2147 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
2148 as size_t, not int.
2149 * builtin.c (dump_args): Declare len as size_t, not int.
2151 * debug.c: Prototype the forward declaration of debug_set_file.
2153 * builtin.c (m4_undivert): Replace div by file, for avoiding the
2154 shadowing of this variable.
2155 * output.c (insert_diversion): Idem.
2157 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
2158 (input_init): Duplicate default quote and comment strings.

2167 * m4.c (usage): Reorganize the --help output by topic. Include a
2168 description for debugging flags.
2170 Fri Jul 29 10:15:52 1994 Francois Pinard (pinard@icule)
2172 * configure.in: If sigaction is available and SA_ONSTACK defined,
2173 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
2174 defined, use sigvec. Else don't compile stackovf.c.
2175 * stackovf.c (setup_stackovf_trap): Idem.
2176 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
2177 and Simon Leinen.
2179 Thu Jul 21 22:43:17 1994 Francois Pinard (pinard@icule)
2181 * m4.c (usage): Replace printf par fputs.
2182 \f
2183 Mon Jul 18 23:48:23 1994 Francois Pinard (pinard@icule)
2185 * Release 1.2
2187 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
2189 * configure.in: Check for sigaction and sigvec. Add a new delayed
2190 check for RLIMIT_STACK, combine in the checking for getrlimit.
2191 All those things are not universally available.
2192 * stackovf.c: Split setting up the trap handler and catching
2193 signals, for better taking care of various configure outcomes.
2194 * examples/stackovf.sh: Correct a typo.
2195 Reported by Eric Backus, Jim Avera and Jim Meyering.
2197 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)
2199 * ansi2knr.c: New version sent by its author, Peter Deutsch.
2201 Fri Jul 15 14:36:21 1994 Francois Pinard (pinard@icule)
2203 * Makefile.in: Modify so parallel make will not try making
2204 lib/libm4.a twice simultaneously.
2205 Reported by Jim Meyering.
2207 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
2209 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
2210 error message, for when no code possibility exists. Even if this
2211 line is completely #ifdef'ed out, it brings a syntax error.
2212 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
2214 * Makefile.in (install): Have install depend on all too, for lib
2215 to be remade as needed.
2217 * examples/stackovf.sh: Try ksh, bsh and bash for shells
2218 providing ulimit, instead of using only ksh.
2219 Reported by Jim Avera and Joseph E. Sacco.
2221 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
2223 * Makefile.in (check): Have it depend on all instead of m4. In
2224 this way, a change in lib will be detected and processed.
2226 * builtin.c (numeric_arg): Use strtol and verify the conversion,
2227 instead of using sscanf which stops as soon as there is a
2228 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
2229 and divert(1xyzzy) were all accepted without any warning or error
2230 messages.
2231 * m4.h: Declare strtol as long if not including stdlib.h.
2232 * configure.in: Check for limits.h, and replace strtol if missing.
2233 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
2234 * lib/strtol.c: New file, from elsewhere.
2235 Reported by Andreas Schwab.
2237 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
2239 * macro.c (expand_macro): Cast value to (boolean) prior to
2240 assigning it to traced.
2241 Reported by Tom McConnell.
2243 * Makefile.in (m4): Always make all in lib first.
2244 Reported by Jim Meyering.
2246 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
2248 * stackovf.c: Isolated OS-dependent sections; Improved portability,
2249 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
2250 handlers), and a default error message if the fault address is not
2251 available (when neither siginfo.h nor BSD sigcontext are supported).
2252 * configure.in: Changes for stackovf.h: Check for sigcontext,
2253 sigaction, sigstack, and define rlim_t as int if necessary.
2254 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
2255 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
2256 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
2258 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
2260 * configure.in: Use AC_SET_MAKE.
2261 * Makefile.in: Use @SET_MAKE@.
2262 Reported by Jim Meyering.
2264 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
2265 Reported by Ian Taylor.
2267 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
2269 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
2270 because siginfo.h is unrelated to standard headers, and siginfo.h
2271 is already checked for.
2272 Reported by Joseph E. Sacco.
2274 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
2275 PROTOTYPES.
2276 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
2277 AC_PROTOTYPES.
2279 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
2281 * builtin.c (substitute): Use \& to represent this part of the
2282 string which was matched by the whole regexp, instead of
2283 representing the whole string. Any usage of \0 issues a warning
2284 and acts like \&, it will disappear in some subsequent release.
2286 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
2288 * m4.c: Complete prototype for forwarded declaration of usage.
2290 * input.c (init_macro_token): Correct own reference in error
2291 message. Previous name get_macro_func was referred to instead.
2292 (next_char): Correct own reference in error message. Previous
2293 name advance_input was referred to instead.
2295 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
2296 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
2297 and_term, not_term, logical_not_term, cmp_term, shift_term,
2298 add_term, mult_term, exp_term, unary_term, simple_term): Add
2299 prototype to forwarded declarations. Declare parameter v1 as
2300 eval_t * instead of int *. Same for local variable v2 in dyadic
2301 functions. Same for result in exp_term.
2302 * builtin.c (m4_eval): Declare value as eval_t instead of int.
2303 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
2304 unsigned_eval_t instead of unsigned int. Change casts accordingly.
2305 (shipout_int): Cast first argument of ntoa to eval_t.
2306 Reported by Thorsten Ohl.
2308 * macro.c: Complete the prototypes of forwarded expand_macro and
2309 expand_token.
2310 Reported by Thorsten Ohl.
2312 * m4.h: Define voidstar as void * or char * depending on __STDC__.
2313 The Ultrix 3.1 compiler cannot do much with void pointers.
2315 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
2316 * m4.c (xfree): Replace void * by voidstar.
2317 Reported by Tom McConnell.
2319 * ansi2knr.1: New, from elsewhere.
2320 * Makefile.in (DISTFILES): Distribute ansi2knr.1
2322 * Makefile.in (stamp-h.in): Avoid running ./config.status if
2323 stamp-h does not exist yet. This avoids running it a second time
2324 just after the initial ./configure.
2325 Reported by David MacKenzie and Tom McConnell.
2327 * m4.h: Replace the enum debug_info declaration with a series of
2328 #define's. The Ultrix 3.1 compiler would otherwise need casting
2329 (int) to most references, when used in expressions.
2330 Reported by Tom McConnell.
2332 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
2334 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
2335 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
2336 calls the compiler. Previously, FP_PROTOTYPES was only calling
2337 the preprocessor; by not being subject to CFLAGS, this was
2338 discouraging those flags asking for ANSI compilation.
2339 * acconfig.h: Document HAVE_PROTOTYPES.
2340 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
2341 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
2342 Reported by Eric Backus.
2344 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
2345 from the environment. Default CFLAGS to -g if not set.
2346 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
2347 * lib/Makefile.in: Have CFLAGS substituted from configure.
2348 Reported by Eric Backus and Tom McConnell.
2350 * configure.in: m4_undefine changeword before using AC_ENABLE.
2352 * m4.h: Declare prototypes for error (for ANSI compilers only),
2353 prefix_all_builtins and reference_error.
2354 Reported by Tom McConnell.
2356 * input.c (set_word_regexp): Do not try to initialize the array
2357 test from a string, this does not work with non-ANSI compilers.
2358 Reported by Eric Backus.
2360 * Makefile.in (dist): Clean examples/ before saving it.
2361 (distclean-local): Also remove stamp-h.
2362 Reported by Eric Backus.
2364 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
2365 non ANSI compilers.
2366 Reported by Tom McConnell.
2368 * checks/Makefile.in (clean): Depends on mostlyclean.
2369 (mostlyclean): New goal.
2371 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
2373 * Makefile.in (DISTFILES): Distribute install.sh.
2374 * install.sh: New file, copied from elsewhere.
2375 Reported by Assar Westerlund and Kaveh R. Ghazi.
2377 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
2379 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
2380 * acconfig.h: Explain ENABLE_CHANGEWORD.
2382 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
2383 from code provided by Pete Chown]
2384 * m4.h: Add original_text field to u_t variant of union u.
2385 Declare TOKEN_DATA_FUNC macro.
2386 * builtin.c: Declare changeword.
2387 (m4_changeword): New function.
2388 * input.c: Include "regex.h", define variables with word regexps.
2389 (input_init): Initialize the word regexp.
2390 (set_word_regexp): New.
2391 (next_token): Declare local variables, use the previous code if
2392 default_word_regexp is true. Else, match using a new code. Save
2393 the original text.
2394 * macro.c (expand_token): Ship out original text if not a macro
2395 name.
2396 Reported by Krste Asanovic and Pete Chown.
2398 [These modifs all depend upon ENABLE_CHANGEWORD]
2399 * m4.h: Declare external user_word_regexp.
2400 * m4.c: Declare user_word_regexp, and initialize it from
2401 --word-regexp or -W, or NULL if not specified.
2402 * input.c: Use user_word_regexp if specified, instead of
2403 DEFAULT_WORD_REGEXP.
2405 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
2406 agree with it.
2408 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
2409 * checks/Makefile.in: Empty the suffix list.
2410 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
2412 * m4.c: Declare nesting_limit and initialize it to 250.
2413 Implement -LNUMBER or --nesting-limit=NUMBER to change its
2414 value.
2415 * m4.h: Declare nesting_limit as external.
2416 * macro.c (expand_macro): Stop execution whenever nesting limit
2417 is exceeded.
2418 Reported by Bengt Mertensson.
2420 * eval.c (evaluate): Diagnose excess characters in eval input.
2421 Things like `eval(08)' used to return 0 with no diagnostic.
2423 * m4.h: Capitalize first letter of all macro arguments in
2424 definitions.
2426 * m4.c: Declare warning_status, initialize it to 0. Add new
2427 option -E, or --fatal-warnings, which sets warning_status to
2428 EXIT_FAILURE instead.
2429 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
2430 EXIT_FAILURE if not otherwise done by header files.
2431 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
2432 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
2433 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
2434 argument of all M4ERROR calls.
2435 Reported by Noah Friedman.
2437 * examples/incl-test.m4: Renamed from incl_test.m4.
2438 * examples/include.m4: Include incl-test.m4 instead of
2439 incl_test.m4.
2440 * examples/multiquotes.m4: Renamed from multi-quotes.m.
2442 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
2444 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
2445 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
2446 also tested it on a Sun Sparc workstation running SunOS 4.x.
2448 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
2449 49.format check, abusing a `union values' argument with sprintf
2450 without selecting the proper field. Now, save the formatting type
2451 first, delaying the fetch of the corresponding argument.
2452 Reported by Joseph E. Sacco and Tom Quinn.
2454 * format.c (format): Remove const from char *fmt declaration when
2455 not HAVE_EFGCVT, because a NUL may be forced into it.
2457 * m4.h: Declare atof() when not STDC_HEADERS.
2458 Reported by Joseph E. Sacco.
2460 * Regenerate configure using Autoconf 1.11, this corrects a
2461 problem about an incorrect cpp seting on NeXT 3.1.
2462 Reported by Alexander Lehmann.
2464 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
2466 * m4.h (_): Change argument from `x' to `Args'.
2468 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
2470 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
2471 bringing more evil than good on a few systems.
2472 Reported by Greg A. Woods.
2474 Fri Apr 22 15:59:35 1994 Francois Pinard (pinard@icule)
2476 * m4.h: Rename Args() to _().
2477 * m4.h: Remove extern specifier from all function declarations.
2479 Fri Apr 22 15:51:21 1994 Jim Avera (jima@netcom.com)
2481 * stackovf.c: New file implementing stack-overflow detection.
2482 * configure.in: Check for getrlimit, sigaction. If all of
2483 standard headers, getrlimit and sigaction, define USE_STACKOVF and
2484 substitute ${U}stackovf.o for STACKOVF.
2485 * acconfig.h: Declare USE_STACKOVF.
2486 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
2487 * m4.h: Declare setup_stackovf_trap().
2488 * m4.c: Call setup_stackovf_trap().
2489 * tests/stackovf_test.sh: New file.
2491 Wed Apr 13 14:10:30 1994 Francois Pinard (pinard@icule)
2493 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
2495 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
2497 Sun Jan 30 14:24:19 1994 (pinard at icule)
2499 * m4.h: Remove definition of volatile, not used anymore.
2500 Reported by Jim Meyering and Joseph E. Sacco.
2502 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
2503 of `if ... else /* nothing */' for if macros.
2504 Reported by Jim Meyering.
2506 * builtin.c (m4_regexp): Reorganize the code for avoiding a
2507 warning from gcc about `repl' possibly used before defined.
2508 Reported by Jim Meyering.
2510 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
2511 Reported by Jim Meyering.
2513 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
2515 * m4.h: Move the conditional definition of volatile after the
2516 inclusion of system files, because they may define it first.
2518 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
2520 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
2521 get around a problem with Alpha make seeing a syntax error, there.
2522 Reported by Vern Paxson.
2524 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
2526 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
2527 Reported by Richard Stallman.
2529 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)

2532 instead of AC_HAVE_FUNCS.
2533 Reported by Noah Friedman.
2535 Wed Dec 1 09:37:53 1993 Francois Pinard (pinard@icule)
2537 * m4.c: Initialize show_help and show_version to zero.
2539 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
2540 Use them in exit() and usage() calls.
2542 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
2544 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
2545 syserr() macro. Delete errref, add reference_error and M4ERROR.
2546 * m4.c: Replace errref, which was returning an input reference
2547 string, with reference_error, which prints it on standard error.
2548 * builtin.c, output.c: Use errno as second parameter to error,
2549 instead of using syserr() with %s.
2550 * *.c: Use M4ERROR instead of error: no more errref() with %s.
2551 Doing so, the program name appears after the input reference
2552 instead of before, which eases M-x next-error processing.
2554 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
2556 * checks/get-them: Escape braces with backslashes in patterns,
2557 because HPUX-9.01 awk needs this.

2560 Mon Nov 22 10:55:52 1993 Francois Pinard (pinard@icule)
2562 * builtin.c: Declare "FILE *popen ();".

2566 Declare xrealloc, for use in errref().
2567 * m4.c: Delete error_message_prefix() function, add errref().
2568 * *.c: Use error() systematically in place of all error macros,
2569 now that error() flushes stdout first. Make needed adjustments.
2571 * m4.h: Remove const in sys_errlist[] declaration, it creates
2572 conflicts on SGI and Alpha.
2573 Reported by Kaveh R. Ghazi.
2575 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)

2581 * Makefile.in: Distribute acconfig.h, .stamp-h.in and config.h.in,
2582 use them wherever appropriate. Also use -I. for compilations.
2583 * lib/Makefile.in: Use -I.. for compilations.
2584 * *.c: Include <config.h> or "config.h".
2586 * m4.h: Test for HAVE_MEMORY_H instead of NEED_MEMORY_H.
2587 * configure.in: Use AC_HAVE_HEADERS(memory.h), delete AC_MEMORY_H.
2589 Wed Nov 17 09:34:55 1993 Francois Pinard (pinard@icule)
2591 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
2593 * input.c (input_init): Initialize quote and comment strings
2594 explicitely instead of calling set_quotes and set_comment: by
2595 doing so, we ensure we do not free uninitialized variables.
2597 * checks/check-them: Reverse arguments to both diff, so the
2598 expected is on the left and the obtained on the right.
2600 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
2601 macros. Delete declarations for m4error, warning, fatal and
2602 internal_error, add declaration for error_message_prefix.
2603 * m4.c: Delete m4error, warning, fatal and internal_error
2604 routines, add error_message_prefix routine.
2605 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
2606 warning with WARNING*, fatal with FATAL* and internal_error with
2607 INTERNAL_ERROR*.
2608 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
2609 this is not needed anymore.
2611 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
2612 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
2613 and debug_message, add declaration for debug_message_prefix.
2614 * debug.c: Remove static specifier for FILE *debug declaration.
2615 Delete debug_print and debug_message routines, add
2616 debug_message_prefix routine.
2617 * builtin.c, debug.c: Replace debug_print routine calls with
2618 DEBUG_PRINT* macro calls.

2623 * debug.c: Include <stdarg.h> or <varargs.h>.
2624 (trace_format): Use stdarg instead of varargs if __STDC__.
2626 * configure.in: Remove checks for vfprintf and _doprnt. These
2627 implementations use varargs tricks which are not portable enough.
2628 * lib/vfprintf.c: Deleted.
2629 * lib/_doprnt.c: Deleted.
2630 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.
2631 Reported by Joel Sherrill.

2647 Fri Nov 12 10:02:26 1993 Francois Pinard (pinard@icule)
2649 * Makefile.in (m4.dvi): Use m4.texinfo instead of m4.texi.
2650 Reported by Joel Sherrill.
2652 * builtin.c (prefix_all_builtins): Instead of the table size, use
2653 the null entry at end for stopping the loop. It was overwritten.
2654 Reported by Andreas Schwab and Jim Meyering.
2656 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
2657 Reported by Kaveh R. Ghazi.

2674 * m4.h: Define strchr and strrchr in terms of index and rindex,
2675 instead of the other way around.

2679 Reported by Tom McConnell.
2680 \f
2681 Mon Nov 8 12:45:34 1993 Francois Pinard (pinard@icule)
2683 * Release 1.1
2685 * configure.in: Do not copy check files in the build hierarchy.

2693 Reported by Tom McConnell.
2695 * Makefile.in (Makefile): Use $(SHELL).
2696 (config.status): Use $(SHELL). Use "config.status --recheck"
2697 instead of "configure --no-create", which is obsolete.
2698 Reported by Tom McConnell.
2700 Fri Nov 5 09:49:30 1993 Francois Pinard (pinard@compy.IRO.UMontreal.CA)

2736 Reported by Jim Avera.
2738 * builtin.c (m4_ifelse): Diagnose excess arguments if 5, 8, 11,

2847 ensure 777 mode for directories, so older tar's will restore file
2848 modes properly.
2850 Sun Jan 17 15:38:05 1993 Francois Pinard (pinard@icule)
2852 * Makefile.in, lib/Makefile.in: Put $(CFLAGS) after $(CPPFLAGS),

2913 * lib/alloca.c: New, from elsewhere.
2914 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
2916 * m4.h: Do not define index/rindex if already defined. If
2917 FALSE/TRUE are already defined, do not redefine them, but merely
2918 define boolean typedef to int.
2920 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
2921 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
2922 because some C compilers do not like connectives with #ifdef.
2923 * m4.h: Define `volatile' only if __GNUC__, instead of once for
2924 __GNUC__ and once for __STDC__.
2925 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
2927 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
2928 Makefile dependencies. Without it, make keeps destroying and
2929 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
2931 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
2932 to diversion/DIVERSION, this was a spelling error.
2934 * m4.c: Declare version[], remove #include "version.h".
2935 * version.h: Deleted.
2936 * Makefile.in: Remove references to version.h.
2938 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
2939 production, by using a simpler and more robust algorithm. This
2940 solves the problem of synclines sometimes written in the middle of
2941 an output line. Delete sync_line() and output_lines variable.
2942 * m4.h: Remove sync_line prototype and output_lines declaration.
2943 * input.c (next_char), output.c (shipout_text): Remove references
2944 to output_lines.
2945 * input.c (push_file, pop_file): Merely put the value -1 in
2946 output_current_line instead of calling sync_line, for delaying a
2947 single `#line NUM FILE' before next output line. Do not test
2948 for sync_output, because this is unnecessary clutter.
2949 * output.c (make_divertion, insert_divertion): Idem.
2950 * input.c: Rename must_advance_line to start_of_input_line, for
2951 consistency.
2953 * debug.c (trace_header): Select a new debug line format, which
2954 better complies with GNU standards for formatting error messages.
2955 With option `-dfl', M-x next-error might be used on the output.
2956 * m4.c (vmesg): Adjust format of error output to GNU standards.
2957 * m4.texinfo: Adjust examples for `make check' to work.
2959 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
2960 case for enum debug_info constants, which were all lower case.
2962 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
2963 re_search_2.
2964 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
2965 collected patches. I tried a few times using newer regex.[ch], it
2966 mysteriously stopped aborting with this one. Insecure feeling...
2967 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
2969 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
2971 * m4.c: Change `--no-warnings' to `--silent'.
2972 Reported by David MacKenzie.
2974 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
2975 leave it off for now. See comment in m4.c for justification.
2976 Reported by David MacKenzie.
2978 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
2979 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
2981 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
2983 * Makefile.in: Ensure recursive cleaning is done before local
2984 cleaning for all clean goals.
2986 * builtin.c (ntoa): Ensure the value is always interpreted as a
2987 signed quantity, whatever the radix is.
2989 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
2991 * builtin.c, format.c, input.c: Split long lines.
2992 * m4.c: Use typedef macro_definition instead of struct
2993 macro_definition.
2994 * symtab.c: Use typedef symbol instead of struct symbol.
2996 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
2998 * *.[ch]: Remove all trailing whitespace, in code and comments.
3000 * configure.in: Find some awk.
3001 * Makefile.in: Add $(AWK) to MDEFINES.
3002 * checks/Makefile.in: Transmit $(AWK) to get_them.
3003 * checks/get_them: Use $AWK instead of gawk. Add a close in the
3004 awk script when switching files, because without this, mawk runs
3005 out of file descriptors.
3007 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
3009 * Makefile.in (realclean): Delete m4.info*.
3010 Reported by Jim Meyering.
3012 * Makefile.in: Adjust and link with checks/Makefile.
3013 * checks/Makefile.in: New.
3014 * configure.in: Output checks/Makefile.
3016 * checks/get_them: Have the dnl header of each test more
3017 recognizable by next-error, also use a better message.
3019 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
3021 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
3022 And use that only if __GNUC__ since we're using it's GCC-specific
3023 semantics that tell the compiler the associated function doesn't
3024 return.
3026 * builtin.c (substitute): Don't use character as an array index.
3027 (dumpdef_cmp): Make formal arguments `const void *' to avoid
3028 warnings with gcc -W -Wall on systems with qsort prototype.
3029 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
3030 from gcc -W -Wall.
3032 * eval.c (most functions): Add parentheses to assignments used
3033 as truth values go avoid warnings from gcc -Wall.
3035 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
3036 any functions that don't need external scope.
3038 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
3039 (many functions and arrays): Declare `const'.
3041 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
3043 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
3044 removing the declaration from m4.h. Also rename false to FALSE
3045 and true to TRUE.
3047 * lib/Makefile.in (Makefile): New goal.
3049 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
3050 so heavily loaded. It gets more easily overridable, calling make.
3051 Reported by Jim Meyering.
3053 * Makefile.in (dist): Get .fname from the current directory name,
3054 instead of from version.h. I need updating many files manually,
3055 when the version changes, version.h is just one of them.
3057 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
3059 * m4.h: Remove the tag `boolean' on the enum introducing typedef
3060 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
3061 Reported by Tom McConnell.
3063 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
3065 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
3066 39.cleardiv, which were describing missing or spurious newlines.
3067 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
3068 do not depend on machine word size, `/bin/false' implementation,
3069 or `wc' output format. `make check' is more dependable, now.
3071 * checks/check_them: Summarize the failed tests by listing their
3072 name, at end. If none, issue `All checks successful'. Output
3073 `Checking' instead of `Input file:'.
3075 * checks/get_them, checks/check_them: Reindented.
3077 * Makefile.in (dist): chmod a+r before making the tar file.
3079 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
3081 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
3083 * input.c (next_token): Reinitialize token_buttom just after using
3084 it as a watermark with obstack_free. Or else, a future token, big
3085 enough for triggering reallocation of the obstack chunk, could
3086 void the initialized value of token_buttom, later causing panic in
3087 obstack_free. Rename token_buttom to token_bottom everywhere.
3089 * m4.h: Before declaring errno, first include <errno.h> and
3090 ensure that it does not define errno.
3091 Reported by Richard Stallman.
3093 Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule)
3095 * builtin.c: Define and use DECLARE macro for builtins.
3097 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
3098 argument, this is a common idiom for introducing long comments.
3100 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
3101 arguments. The last argument was silently ignored.
3103 * m4.c (cmd_error): Add a missing semicolon before va_end().
3105 Tue Nov 10 08:57:05 1992 Francois Pinard (pinard at icule)
3107 * Makefile.in: Now handle protoized sources. Define and use U.
3108 Compile and use ansi2knr with old compilers. Update DISTFILES.
3109 Add `aclocal.m4' to `configure' dependencies.
3110 * ansi2knr.c: New, from Ghostscript distribution.
3111 * configure.in: Define U through FP_PROTOTYPES for old compilers.
3112 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
3113 * aclocal.m4: New, provide FP_PROTOTYPES.
3114 * m4.h: Conditionnaly protoized through Args, save for varags.
3115 * builtin.c: Protoized. Then:
3116 Include <sys/types.h> if size_t is not defined, before "regex.h".

3118 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
3119 (m4_regexp): Add const to `msg' declaration.
3120 (m4_patsubst): Add const to `msg' declaration.
3121 * debug.c: Protoized, save for varargs.
3122 * eval.c: Protoized.
3123 * format.c: Protoized.
3124 * input.c: Protoized.
3125 * m4.c: Protoized, save for varargs. Then:
3126 (xfree): Accept void * instead of char *.
3127 (xmalloc): Return void * instead of char *.
3128 (xrealloc): Accept and return void * instead of char *.
3129 * macro.c: Protoized.
3130 * output.c: Protoized.
3131 * path.c: Protoized. Then cast some (char *) over xmalloc's.
3132 * symtab.c: Protoized.
3134 Fri Nov 6 02:05:21 1992 Francois Pinard (pinard at icule)
3136 * m4.texinfo: Remove directory from diagnostics in 30.include,
3137 51.eval, 56.errprint and 57.m4exit tests.
3139 * m4.h: Remove declarations for int or void system functions, they
3140 cause more conflicting trouble than they make good.
3142 * configure.in: Avoid configuration header file. Add some tests.
3143 * m4.h: Remove #include "config.h".
3144 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
3145 Then, rewritten for better compliance with GNU standards.
3147 Thu Nov 5 12:37:13 1992 Francois Pinard (pinard at icule)
3149 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
3150 because of a misplaced #endif.

3166 * version.h: De-automatize, force value in.
3168 * m4.c: Changes in order to use a newer getopt.h.
3169 Reported by David MacKenzie.

3172 * checks/get_them: New location for etc/get_examples.
3173 * checks/check_them: New location for etc/check_examples.

3179 Tue Mar 10 00:29:46 1992 Francois Pinard (pinard at icule)
3181 * Makefile.in (check): Add m4 as dependency.
3183 * m4.c: Accept --no-warnings instead of --no_warnings, and
