1507 Remove double . before suffixes.
1508 (cvs-release): Don't mention manual.html.
1509 (fetch): Get latest gendocs files.
1510 (web-manual): Rewritten to use gendoc for multiformat manuals.
1511 * doc/gendocs.sh: Don't save an old version in m4 CVS!
1512 * doc/m4.texinfo (Index): HFS+ (the file system on my Mac) is case
1513 preserving, but case insensitive, so generating html docs per node
1514 clashes between Index.html, the node file, and index.html, the
1515 top-level of the document tree...
1516 (Index macro): ...so renamed to this. Changed all references.

1538 * doc/m4.texinfo (Patsubst): Re-add trailing space required by
1539 checks/47.patsubst, with a redundant @comment to prevent emacs
1540 from removing it accidentally again.

1573 on Windows, so that the frozen file reader will work.
1574 Reported by Josef T. Burger.
1576 * src/m4.c (main): Modernise the --version output.
1578 2005-02-03 Gary V. Vaughan <gary@gnu.org>
1580 Modernise the configury a little to prevent spurious errors from
1581 Autoconf-2.59's autoreconf:

1584 * config-h.in: ...this to better support DOS 8.3 file systems.
1585 * acconfig.h: Removed.
1586 * configure.in: Renamed to...
1587 * configure.ac: ...this, and AC_DEFINE used to declare config.h
1588 entry comments. Slight reorganisation and reformatting.
1589 * aclocal.m4: Use third argument to AC_DEFINE to declare config.h
1590 entry comments.
1591 (AC_INIT): Use a modern 3 argument call.

1598 (configure): Depends on configure.ac, not configure.in.
1599 * doc/Makefile.in (stamp-vti): Ditto.
1600 * src/freeze.c (produce_frozen_state), src/m4.c (main): Adjust for
1601 difference between PRODUCT="m4" and PACKAGE="GNU M4".

1604 2005-02-03 Noah Misch <noah@cs.caltech.edu>
1606 * src/output.c (mkstemp): Make non-static, and build regardless of
1607 HAVE_TMPFILE; src/builtin.c also needs this replacement.
1608 * NEWS: Update.
1610 2004-09-09 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
1612 * configure.in (AC_CHECK_HEADERS): Commit works best when you save

1615 * configure.in (AC_CHECK_HEADERS): Add signal.h, sys/signal.h.
1616 * src/m4.c: And include them as appropriate.
1617 * NEWS: Updated.
1619 2004-09-09 Andreas Schwab <schwab@suse.de>

1640 relies on this.
1641 * src/builtin.c (m4_esyscmd): Clear errno before calling popen.
1642 (m4_maketemp): Clear errno before calling mkstemp.
1643 * src/path.c (path_search): Don't let "free" trash errno when
1644 returning NULL.
1645 * src/output.c (insert_file): Don't assume errno has a valid
1646 value simply because fread returns zero. This fixes a
1647 portability bug reported by Marion Hakanson in
1648 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
1650 2004-06-09 Gary V. Vaughan <gary@gnu.org>

1672 2003-09-28 Akim Demaille <akim@epita.fr>
1674 * src/symtab.c (lookup_symbol): Fix an uninitialized-variable

1695 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
1696 empty file rather than to a nonexistent file. This closes a common
1697 security hole.
1698 * src/builtin.c (m4_maketemp): Implement the above, by using
1699 mkstemp rather than mktemp. (trivial change)
1701 2000-01-09 Akim Demaille <demaille@inf.enst.fr>
1703 * src/builtin.c (expand_ranges): Added break after trailing dash.
1704 This caused misbehaviors on some systems.

1720 ANSIfying compiler flags, this is of no use to check it before.
1721 Reported by Alexander Lehmann.
1723 Tue Nov 1 22:02:37 1994 Francois Pinard (pinard@icule)
1725 * src/macro.c (collect_arguments): Cast obstack arguments to
1726 (voidstar), so avoiding compiler warnings.
1727 Reported by Joseph E. Sacco.
1729 * src/freeze.c (produce_frozen_state): Cast printed lengths to
1730 (int) so they correspond to %d format items.
1731 Reported by Joseph E. Sacco.
1733 * src/m4.c (main): Cast the argument to xfree to (voidstar).
1734 * src/symtab.c (free_symbol): Idem.

1748 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
1749 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
1750 defines __STDC__ to 0, for indicating it is *not* ANSI!
1751 Reported by Kaveh R. Ghazi.
1753 * configure.in: Added obsolescent tests for AIX and Minix.
1755 * doc/Makefile.in (mostlyclean): Remove texclean in dependencies,
1756 which texclean does not exist anymore.
1757 Reported by Eric Backus, Jim Meyering, John David Anglin and

1767 ANSI2KNR, depending on the fact the compiler is ANSI or not.
1768 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
1769 Remove the sed filter after ansi2knr for debug.c. Use $O instead
1770 of $U, put underline in extensions rather than in basenames. Use
1771 implicit rules, now that regularity makes this possible.
1772 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
1773 of ansi2knr whenever it is needed.
1774 * configure.in: Adjusted for correct STACKOVF substitution.
1775 * src/debug.c (trace_format): When not __STDC__, use (...) as a
1776 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.
1777 Reported by David MacKenzie.
1779 * Makefile.in: Remove binprefix. Use transform_name instead.
1780 Reported by David MacKenzie.
1782 * doc/Makefile.in: Create version.texi, use it, clean it.

1792 Reported by Jim Kingdon.
1794 * {,/*}Makefile.in: Use && after all cd, in case they fail.
1796 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.

1802 Thu Oct 27 22:32:58 1994 Francois Pinard (pinard@icule)
1804 * Makefile.in (mostlyclean-local): Do not remove *~.
1805 * */Makefile.in (mostlyclean): Idem.

1818 Sat Oct 1 11:22:42 1994 Francois Pinard (pinard@icule)
1820 * configure.in: Do not add -O to CFLAGS for GNU C, now that

1822 Reported by Jim Meyering.
1824 Fri Sep 23 08:16:58 1994 Francois Pinard (pinard@icule)
1826 * src/stackovf.c: Declare the handler_t typedef earlier in the
1827 code, use it for stackovf_handler.
1828 (setup_stackovf_trap): Use RETSIGTYPE instead of void while
1829 casting sigsegv_handler.
1830 Reported by Robert Bernstein.
1832 * src/m4.c (main): Initialize program_name to argv[0] without
1833 basename'ing it.

1849 unreacheable and useless.
1851 * doc/Makefile.in (texclean): Deleted, merged in mostlyclean.

1854 (distclean): Do not remove TAGS.
1855 (realclean): Remove it.
1856 * Makefile.in: Make TAGS in lib also, not just in src.
1857 Reported by Karl Berry.
1859 * Makefile.in (distclean, realclean): Instead of recursively
1860 calling $(MAKE) for the -local part, allow parallel execution of
1861 -recursive and -local, only delay the removal of config.status,
1862 which is repeated in both goals.
1863 \f

1866 * Release 1.3.
1868 * Makefile.in: Group all *clean-recursive goals in one, using sed
1869 to remove `-recursive' while calling make recursively. Also, use

1871 Reported by Jim Meyering.
1873 * src/m4.h (memcpy): Define with bcopy for BSD systems.
1874 Reported by Kaveh R. Ghazi.
1876 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
1877 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
1878 specify it.
1880 * configure.in: Use date instead of touch for stamp-h.
1881 * Makefile.in (stamp-h.in): Idem.
1883 * Makefile.in (distclean, realclean): Force serial execution of

1911 Reported by Jim Meyering.
1913 Tue Sep 6 12:07:33 1994 Francois Pinard (pinard@icule)

1916 care of systems having only incomplete implementations (like for
1917 Pyramid 9820 OSx 5.0d).
1918 Reported by Kaveh R. Ghazi.
1920 * src/Makefile.in (TAGS): Remote -t from etags call.
1922 Fri Sep 2 10:37:10 1994 Francois Pinard (pinard@icule)
1924 * lib/Makefile.in (install): Depend on all.

1932 Reported by Jim Meyering.
1934 Solidify frozen files with respect to -P:
1935 * src/m4.c: Have -P set prefix_all_buitins variable instead of
1936 calling a function by that name. Declare the variable.
1937 * src/m4.h: Adjust declaration for prefix_all_buitins.
1938 * src/builtin.c (builtin_init): Merge in functionality from
1939 previous prefix_all_buitins function, while making entries in the
1940 symbol table, but not modifying the builtin description itself.
1942 * src/freeze.c (reload_frozen_state): Add a useless `break;',
1943 because *many* compilers do not accept an empty `default:'.
1944 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
1945 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
1947 * configure.in: Use AC_TYPE_SIGNAL.

1969 * configure.in: Configure new Makefiles.
1971 * m4.h: Declare STRING typedef. Use it for comment and quote
1972 strings, adjusting all references. (This is the rudiments of a
1973 beginning for the eventual withdrawal of NUL terminated strings.)
1974 * output.c (shipout_text): Accept a length parameter, and use it.
1975 All callers adjusted.
1977 Mon Aug 29 12:27:19 1994 Francois Pinard (pinard@icule)
1979 * m4.h: Include <unistd.h> if it exists.

1999 * output.c (freeze_diversions): New function.
2000 * m4.h: Declare freeze_diversions.
2001 * freeze.c: Document frozen file format, revise it, call
2002 freeze_diversions to add diversions to frozen format, and code to
2003 reload them properly.
2004 * m4.c: Do not undivert automatically at end when status being
2005 frozen. Do not call builtin_init when reloading frozen state.
2007 Speed up diversion processing:
2008 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
2009 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion

2024 * symtab.c (hack_all_symbols): Use hash_table_size instead of
2025 constant HASHMAX, for -H option to work better.
2027 * builtin.c (DECLARE): Simplify by using _ ().
2029 * freeze.c: New file.
2030 * Makefile.in: Compile it, distribute it.
2031 * m4.c: Recognize, document and process --freeze-state (-F) and
2032 --reload-state (-R) options. Pass a true flag to builtin_init
2033 only if no reloading some state.
2034 * builtin.c (define_builtin): Remove static specifier.
2035 (find_builtin_by_name): Remove static specifier.
2036 (builtin_init): Accept and obey a flag argument.
2037 * m4.h: Add declarations for freeze.c, changes for builtin.c.
2039 Wed Aug 24 16:14:19 1994 Francois Pinard (pinard@icule)
2041 * builtin.c (dumpdef_cmp): Rewrite so the cast protect the const
2042 specifier.
2044 * configure.in: Implement --with-dmalloc.
2045 * acconfig.h: Document WITH_DMALLOC.
2046 * m4.h: Add code for when WITH_DMALLOC.
2048 Mon Aug 15 12:38:05 1994 Francois Pinard (pinard@icule)
2050 * m4.c (long_options): Use "error-output", the dash was missing.
2051 Reported by Akiko Matsushita.
2053 Fri Aug 12 16:38:01 1994 Francois Pinard (pinard@icule)
2055 * m4.h: Include <sys/types.h>.
2056 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
2057 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
2058 int.
2059 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
2060 as size_t, not int.
2061 * builtin.c (dump_args): Declare len as size_t, not int.
2063 * debug.c: Prototype the forward declaration of debug_set_file.
2065 * builtin.c (m4_undivert): Replace div by file, for avoiding the
2066 shadowing of this variable.
2067 * output.c (insert_diversion): Idem.
2069 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
2070 (input_init): Duplicate default quote and comment strings.
2071 (set_quotes): Free previous quote strings in all cases. Duplicate
2072 even default quote strings.
2073 (set_comment): Free previous comment strings in all cases.
2074 Duplicate even default comment strings.
2076 * configure.in: Updated for Autoconf 2.0.
2077 * Makefile.in (distclean-local): Also delete config.cache.
2079 * m4.c (usage): Reorganize the --help output by topic. Include a
2080 description for debugging flags.
2082 Fri Jul 29 10:15:52 1994 Francois Pinard (pinard@icule)
2084 * configure.in: If sigaction is available and SA_ONSTACK defined,
2085 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
2086 defined, use sigvec. Else don't compile stackovf.c.
2087 * stackovf.c (setup_stackovf_trap): Idem.
2088 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
2089 and Simon Leinen.
2091 Thu Jul 21 22:43:17 1994 Francois Pinard (pinard@icule)
2093 * m4.c (usage): Replace printf par fputs.
2094 \f
2095 Mon Jul 18 23:48:23 1994 Francois Pinard (pinard@icule)
2097 * Release 1.2
2099 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
2101 * configure.in: Check for sigaction and sigvec. Add a new delayed
2102 check for RLIMIT_STACK, combine in the checking for getrlimit.
2103 All those things are not universally available.
2104 * stackovf.c: Split setting up the trap handler and catching
2105 signals, for better taking care of various configure outcomes.
2106 * examples/stackovf.sh: Correct a typo.
2107 Reported by Eric Backus, Jim Avera and Jim Meyering.
2109 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)
2111 * ansi2knr.c: New version sent by its author, Peter Deutsch.
2113 Fri Jul 15 14:36:21 1994 Francois Pinard (pinard@icule)
2115 * Makefile.in: Modify so parallel make will not try making
2116 lib/libm4.a twice simultaneously.
2117 Reported by Jim Meyering.
2119 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
2121 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
2122 error message, for when no code possibility exists. Even if this
2123 line is completely #ifdef'ed out, it brings a syntax error.
2124 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
2126 * Makefile.in (install): Have install depend on all too, for lib
2127 to be remade as needed.
2129 * examples/stackovf.sh: Try ksh, bsh and bash for shells
2130 providing ulimit, instead of using only ksh.
2131 Reported by Jim Avera and Joseph E. Sacco.
2133 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
2135 * Makefile.in (check): Have it depend on all instead of m4. In
2136 this way, a change in lib will be detected and processed.
2138 * builtin.c (numeric_arg): Use strtol and verify the conversion,
2139 instead of using sscanf which stops as soon as there is a
2140 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
2141 and divert(1xyzzy) were all accepted without any warning or error
2142 messages.
2143 * m4.h: Declare strtol as long if not including stdlib.h.
2144 * configure.in: Check for limits.h, and replace strtol if missing.
2145 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
2146 * lib/strtol.c: New file, from elsewhere.
2147 Reported by Andreas Schwab.
2149 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
2151 * macro.c (expand_macro): Cast value to (boolean) prior to
2152 assigning it to traced.
2153 Reported by Tom McConnell.
2155 * Makefile.in (m4): Always make all in lib first.
2156 Reported by Jim Meyering.
2158 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
2160 * stackovf.c: Isolated OS-dependent sections; Improved portability,
2161 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
2162 handlers), and a default error message if the fault address is not
2163 available (when neither siginfo.h nor BSD sigcontext are supported).
2164 * configure.in: Changes for stackovf.h: Check for sigcontext,
2165 sigaction, sigstack, and define rlim_t as int if necessary.
2166 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
2167 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
2168 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
2170 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
2172 * configure.in: Use AC_SET_MAKE.
2173 * Makefile.in: Use @SET_MAKE@.
2174 Reported by Jim Meyering.
2176 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
2177 Reported by Ian Taylor.
2179 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
2181 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
2182 because siginfo.h is unrelated to standard headers, and siginfo.h
2183 is already checked for.
2184 Reported by Joseph E. Sacco.
2186 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
2187 PROTOTYPES.
2188 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
2189 AC_PROTOTYPES.
2191 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
2193 * builtin.c (substitute): Use \& to represent this part of the
2194 string which was matched by the whole regexp, instead of
2195 representing the whole string. Any usage of \0 issues a warning
2196 and acts like \&, it will disappear in some subsequent release.
2198 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
2200 * m4.c: Complete prototype for forwarded declaration of usage.
2202 * input.c (init_macro_token): Correct own reference in error
2203 message. Previous name get_macro_func was referred to instead.
2204 (next_char): Correct own reference in error message. Previous
2205 name advance_input was referred to instead.
2207 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
2208 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
2209 and_term, not_term, logical_not_term, cmp_term, shift_term,
2210 add_term, mult_term, exp_term, unary_term, simple_term): Add
2211 prototype to forwarded declarations. Declare parameter v1 as
2212 eval_t * instead of int *. Same for local variable v2 in dyadic
2213 functions. Same for result in exp_term.
2214 * builtin.c (m4_eval): Declare value as eval_t instead of int.
2215 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
2216 unsigned_eval_t instead of unsigned int. Change casts accordingly.
2217 (shipout_int): Cast first argument of ntoa to eval_t.
2218 Reported by Thorsten Ohl.
2220 * macro.c: Complete the prototypes of forwarded expand_macro and
2221 expand_token.
2222 Reported by Thorsten Ohl.
2224 * m4.h: Define voidstar as void * or char * depending on __STDC__.
2225 The Ultrix 3.1 compiler cannot do much with void pointers.
2227 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
2228 * m4.c (xfree): Replace void * by voidstar.
2229 Reported by Tom McConnell.
2231 * ansi2knr.1: New, from elsewhere.
2232 * Makefile.in (DISTFILES): Distribute ansi2knr.1
2234 * Makefile.in (stamp-h.in): Avoid running ./config.status if
2235 stamp-h does not exist yet. This avoids running it a second time
2236 just after the initial ./configure.
2237 Reported by David MacKenzie and Tom McConnell.
2239 * m4.h: Replace the enum debug_info declaration with a series of
2240 #define's. The Ultrix 3.1 compiler would otherwise need casting
2241 (int) to most references, when used in expressions.
2242 Reported by Tom McConnell.
2244 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
2246 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
2247 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
2248 calls the compiler. Previously, FP_PROTOTYPES was only calling
2249 the preprocessor; by not being subject to CFLAGS, this was
2250 discouraging those flags asking for ANSI compilation.
2251 * acconfig.h: Document HAVE_PROTOTYPES.
2252 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
2253 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
2254 Reported by Eric Backus.
2256 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
2257 from the environment. Default CFLAGS to -g if not set.
2258 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
2259 * lib/Makefile.in: Have CFLAGS substituted from configure.
2260 Reported by Eric Backus and Tom McConnell.
2262 * configure.in: m4_undefine changeword before using AC_ENABLE.
2264 * m4.h: Declare prototypes for error (for ANSI compilers only),
2265 prefix_all_builtins and reference_error.
2266 Reported by Tom McConnell.
2268 * input.c (set_word_regexp): Do not try to initialize the array
2269 test from a string, this does not work with non-ANSI compilers.
2270 Reported by Eric Backus.
2272 * Makefile.in (dist): Clean examples/ before saving it.
2273 (distclean-local): Also remove stamp-h.
2274 Reported by Eric Backus.
2276 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
2277 non ANSI compilers.
2278 Reported by Tom McConnell.
2280 * checks/Makefile.in (clean): Depends on mostlyclean.
2281 (mostlyclean): New goal.
2283 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
2285 * Makefile.in (DISTFILES): Distribute install.sh.
2286 * install.sh: New file, copied from elsewhere.
2287 Reported by Assar Westerlund and Kaveh R. Ghazi.
2289 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
2291 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
2292 * acconfig.h: Explain ENABLE_CHANGEWORD.
2294 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
2295 from code provided by Pete Chown]
2296 * m4.h: Add original_text field to u_t variant of union u.
2297 Declare TOKEN_DATA_FUNC macro.
2298 * builtin.c: Declare changeword.
2299 (m4_changeword): New function.
2300 * input.c: Include "regex.h", define variables with word regexps.
2301 (input_init): Initialize the word regexp.
2302 (set_word_regexp): New.
2303 (next_token): Declare local variables, use the previous code if
2304 default_word_regexp is true. Else, match using a new code. Save
2305 the original text.
2306 * macro.c (expand_token): Ship out original text if not a macro
2307 name.
2308 Reported by Krste Asanovic and Pete Chown.
2310 [These modifs all depend upon ENABLE_CHANGEWORD]
2311 * m4.h: Declare external user_word_regexp.
2312 * m4.c: Declare user_word_regexp, and initialize it from
2313 --word-regexp or -W, or NULL if not specified.
2314 * input.c: Use user_word_regexp if specified, instead of
2315 DEFAULT_WORD_REGEXP.
2317 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
2318 agree with it.
2320 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
2321 * checks/Makefile.in: Empty the suffix list.
2322 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
2324 * m4.c: Declare nesting_limit and initialize it to 250.
2325 Implement -LNUMBER or --nesting-limit=NUMBER to change its
2326 value.
2327 * m4.h: Declare nesting_limit as external.
2328 * macro.c (expand_macro): Stop execution whenever nesting limit
2329 is exceeded.
2330 Reported by Bengt Mertensson.
2332 * eval.c (evaluate): Diagnose excess characters in eval input.
2333 Things like `eval(08)' used to return 0 with no diagnostic.
2335 * m4.h: Capitalize first letter of all macro arguments in
2336 definitions.
2338 * m4.c: Declare warning_status, initialize it to 0. Add new
2339 option -E, or --fatal-warnings, which sets warning_status to
2340 EXIT_FAILURE instead.
2341 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
2342 EXIT_FAILURE if not otherwise done by header files.
2343 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
2344 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
2345 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
2346 argument of all M4ERROR calls.
2347 Reported by Noah Friedman.
2349 * examples/incl-test.m4: Renamed from incl_test.m4.
2350 * examples/include.m4: Include incl-test.m4 instead of
2351 incl_test.m4.
2352 * examples/multiquotes.m4: Renamed from multi-quotes.m.
2354 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
2356 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
2357 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
2358 also tested it on a Sun Sparc workstation running SunOS 4.x.
2360 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
2361 49.format check, abusing a `union values' argument with sprintf
2362 without selecting the proper field. Now, save the formatting type
2363 first, delaying the fetch of the corresponding argument.
2364 Reported by Joseph E. Sacco and Tom Quinn.
2366 * format.c (format): Remove const from char *fmt declaration when
2367 not HAVE_EFGCVT, because a NUL may be forced into it.
2369 * m4.h: Declare atof() when not STDC_HEADERS.
2370 Reported by Joseph E. Sacco.
2372 * Regenerate configure using Autoconf 1.11, this corrects a
2373 problem about an incorrect cpp seting on NeXT 3.1.
2374 Reported by Alexander Lehmann.
2376 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
2378 * m4.h (_): Change argument from `x' to `Args'.
2380 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
2382 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
2383 bringing more evil than good on a few systems.
2384 Reported by Greg A. Woods.
2386 Fri Apr 22 15:59:35 1994 Francois Pinard (pinard@icule)
2388 * m4.h: Rename Args() to _().
2389 * m4.h: Remove extern specifier from all function declarations.
2391 Fri Apr 22 15:51:21 1994 Jim Avera (jima@netcom.com)
2393 * stackovf.c: New file implementing stack-overflow detection.
2394 * configure.in: Check for getrlimit, sigaction. If all of
2395 standard headers, getrlimit and sigaction, define USE_STACKOVF and
2396 substitute ${U}stackovf.o for STACKOVF.
2397 * acconfig.h: Declare USE_STACKOVF.
2398 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
2399 * m4.h: Declare setup_stackovf_trap().
2400 * m4.c: Call setup_stackovf_trap().
2401 * tests/stackovf_test.sh: New file.
2403 Wed Apr 13 14:10:30 1994 Francois Pinard (pinard@icule)
2405 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
2407 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
2409 Sun Jan 30 14:24:19 1994 (pinard at icule)
2411 * m4.h: Remove definition of volatile, not used anymore.
2412 Reported by Jim Meyering and Joseph E. Sacco.
2414 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
2415 of `if ... else /* nothing */' for if macros.
2416 Reported by Jim Meyering.
2418 * builtin.c (m4_regexp): Reorganize the code for avoiding a
2419 warning from gcc about `repl' possibly used before defined.
2420 Reported by Jim Meyering.
2422 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
2423 Reported by Jim Meyering.
2425 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
2427 * m4.h: Move the conditional definition of volatile after the
2428 inclusion of system files, because they may define it first.
2430 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
2432 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
2433 get around a problem with Alpha make seeing a syntax error, there.
2434 Reported by Vern Paxson.
2436 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
2438 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
2439 Reported by Richard Stallman.
2441 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)
2443 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
2444 instead of AC_HAVE_FUNCS.
2445 Reported by Noah Friedman.
2447 Wed Dec 1 09:37:53 1993 Francois Pinard (pinard@icule)
2449 * m4.c: Initialize show_help and show_version to zero.
2451 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
2452 Use them in exit() and usage() calls.
2454 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
2456 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
2457 syserr() macro. Delete errref, add reference_error and M4ERROR.
2458 * m4.c: Replace errref, which was returning an input reference
2459 string, with reference_error, which prints it on standard error.
2460 * builtin.c, output.c: Use errno as second parameter to error,
2461 instead of using syserr() with %s.
2462 * *.c: Use M4ERROR instead of error: no more errref() with %s.
2463 Doing so, the program name appears after the input reference
2464 instead of before, which eases M-x next-error processing.
2466 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
2468 * checks/get-them: Escape braces with backslashes in patterns,
2469 because HPUX-9.01 awk needs this.
2470 Reported by Jim Meyering.
2472 Mon Nov 22 10:55:52 1993 Francois Pinard (pinard@icule)
2474 * builtin.c: Declare "FILE *popen ();".
2476 * m4.h: Remove MESSAGE{,1,2}, WARNING1, FATAL{,1}, INTERNAL_ERROR
2477 macros, replace error_message_prefix() declaration by errref()'s.
2478 Declare xrealloc, for use in errref().
2479 * m4.c: Delete error_message_prefix() function, add errref().
2480 * *.c: Use error() systematically in place of all error macros,
2481 now that error() flushes stdout first. Make needed adjustments.
2483 * m4.h: Remove const in sys_errlist[] declaration, it creates
2484 conflicts on SGI and Alpha.
2485 Reported by Kaveh R. Ghazi.
2487 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)
2489 * m4.c: Include <getopt.h> instead of "getopt.h".
2491 * configure.in: Output to config.h. Use HAVE_FUNCS preferably.
2492 * acconfig.h: New, for documenting HAVE_EFGCVT.
2493 * Makefile.in: Distribute acconfig.h, .stamp-h.in and config.h.in,
2494 use them wherever appropriate. Also use -I. for compilations.
2495 * lib/Makefile.in: Use -I.. for compilations.
2496 * *.c: Include <config.h> or "config.h".
2498 * m4.h: Test for HAVE_MEMORY_H instead of NEED_MEMORY_H.
2499 * configure.in: Use AC_HAVE_HEADERS(memory.h), delete AC_MEMORY_H.
2501 Wed Nov 17 09:34:55 1993 Francois Pinard (pinard@icule)
2503 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
2505 * input.c (input_init): Initialize quote and comment strings
2506 explicitely instead of calling set_quotes and set_comment: by
2507 doing so, we ensure we do not free uninitialized variables.
2509 * checks/check-them: Reverse arguments to both diff, so the
2510 expected is on the left and the obtained on the right.

2516 routines, add error_message_prefix routine.
2517 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
2518 warning with WARNING*, fatal with FATAL* and internal_error with
2519 INTERNAL_ERROR*.

2562 Reported by Joel Sherrill.
2564 * builtin.c (prefix_all_builtins): Instead of the table size, use
2565 the null entry at end for stopping the loop. It was overwritten.

2759 ensure 777 mode for directories, so older tar's will restore file
2760 modes properly.
2762 Sun Jan 17 15:38:05 1993 Francois Pinard (pinard@icule)
2764 * Makefile.in, lib/Makefile.in: Put $(CFLAGS) after $(CPPFLAGS),

2796 macro.c, output.c, path.c, symtab.c: Change Copyright from
2797 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.

2807 Sun Dec 20 10:40:20 1992 Francois Pinard (pinard at icule)
2809 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user
2810 might well use CFLAGS is s/he needs it.
2812 * Makefile.in: Allow installation of info files from a separate
2813 build directory.
2814 Reported by Jason Merrill.
2815 Reported by David MacKenzie.
2816 Reported by Skip Montanaro.
2817 Reported by Erez Zadok.
2818 Reported by Assar Westerlund.
2819 \f
2820 Sat Dec 19 08:21:34 1992 Francois Pinard (pinard at icule)
2822 * Release 1.0.3
2823 This is still a beta release for the future GNU m4 version 1.1.
2825 * lib/alloca.c: New, from elsewhere.
2826 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
2828 * m4.h: Do not define index/rindex if already defined. If
2829 FALSE/TRUE are already defined, do not redefine them, but merely
2830 define boolean typedef to int.
2832 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
2833 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
2834 because some C compilers do not like connectives with #ifdef.
2835 * m4.h: Define `volatile' only if __GNUC__, instead of once for
2836 __GNUC__ and once for __STDC__.
2837 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
2839 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
2840 Makefile dependencies. Without it, make keeps destroying and
2841 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
2843 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
2844 to diversion/DIVERSION, this was a spelling error.
2846 * m4.c: Declare version[], remove #include "version.h".
2847 * version.h: Deleted.
2848 * Makefile.in: Remove references to version.h.
2850 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
2851 production, by using a simpler and more robust algorithm. This
2852 solves the problem of synclines sometimes written in the middle of
2853 an output line. Delete sync_line() and output_lines variable.
2854 * m4.h: Remove sync_line prototype and output_lines declaration.
2855 * input.c (next_char), output.c (shipout_text): Remove references
2856 to output_lines.
2857 * input.c (push_file, pop_file): Merely put the value -1 in
2858 output_current_line instead of calling sync_line, for delaying a
2859 single `#line NUM FILE' before next output line. Do not test
2860 for sync_output, because this is unnecessary clutter.
2861 * output.c (make_divertion, insert_divertion): Idem.
2862 * input.c: Rename must_advance_line to start_of_input_line, for
2863 consistency.
2865 * debug.c (trace_header): Select a new debug line format, which
2866 better complies with GNU standards for formatting error messages.
2867 With option `-dfl', M-x next-error might be used on the output.
2868 * m4.c (vmesg): Adjust format of error output to GNU standards.
2869 * m4.texinfo: Adjust examples for `make check' to work.
2871 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
2872 case for enum debug_info constants, which were all lower case.
2874 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
2875 re_search_2.
2876 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
2877 collected patches. I tried a few times using newer regex.[ch], it
2878 mysteriously stopped aborting with this one. Insecure feeling...
2879 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
2881 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
2883 * m4.c: Change `--no-warnings' to `--silent'.
2884 Reported by David MacKenzie.
2886 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
2887 leave it off for now. See comment in m4.c for justification.
2888 Reported by David MacKenzie.
2890 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
2891 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
2893 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
2895 * Makefile.in: Ensure recursive cleaning is done before local
2896 cleaning for all clean goals.
2898 * builtin.c (ntoa): Ensure the value is always interpreted as a
2899 signed quantity, whatever the radix is.
2901 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
2903 * builtin.c, format.c, input.c: Split long lines.
2904 * m4.c: Use typedef macro_definition instead of struct
2905 macro_definition.
2906 * symtab.c: Use typedef symbol instead of struct symbol.
2908 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
2910 * *.[ch]: Remove all trailing whitespace, in code and comments.
2912 * configure.in: Find some awk.
2913 * Makefile.in: Add $(AWK) to MDEFINES.
2914 * checks/Makefile.in: Transmit $(AWK) to get_them.
2915 * checks/get_them: Use $AWK instead of gawk. Add a close in the
2916 awk script when switching files, because without this, mawk runs
2917 out of file descriptors.
2919 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
2921 * Makefile.in (realclean): Delete m4.info*.
2922 Reported by Jim Meyering.
2924 * Makefile.in: Adjust and link with checks/Makefile.
2925 * checks/Makefile.in: New.
2926 * configure.in: Output checks/Makefile.
2928 * checks/get_them: Have the dnl header of each test more
2929 recognizable by next-error, also use a better message.
2931 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
2933 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
2934 And use that only if __GNUC__ since we're using it's GCC-specific
2935 semantics that tell the compiler the associated function doesn't
2936 return.
2938 * builtin.c (substitute): Don't use character as an array index.
2939 (dumpdef_cmp): Make formal arguments `const void *' to avoid
2940 warnings with gcc -W -Wall on systems with qsort prototype.
2941 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
2942 from gcc -W -Wall.
2944 * eval.c (most functions): Add parentheses to assignments used
2945 as truth values go avoid warnings from gcc -Wall.
2947 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
2948 any functions that don't need external scope.
2950 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
2951 (many functions and arrays): Declare `const'.
2953 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
2955 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
2956 removing the declaration from m4.h. Also rename false to FALSE
2957 and true to TRUE.
2959 * lib/Makefile.in (Makefile): New goal.
2961 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
2962 so heavily loaded. It gets more easily overridable, calling make.
2963 Reported by Jim Meyering.
2965 * Makefile.in (dist): Get .fname from the current directory name,
2966 instead of from version.h. I need updating many files manually,
2967 when the version changes, version.h is just one of them.
2969 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
2971 * m4.h: Remove the tag `boolean' on the enum introducing typedef
2972 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
2973 Reported by Tom McConnell.
2975 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
2977 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
2978 39.cleardiv, which were describing missing or spurious newlines.
2979 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
2980 do not depend on machine word size, `/bin/false' implementation,
2981 or `wc' output format. `make check' is more dependable, now.
2983 * checks/check_them: Summarize the failed tests by listing their
2984 name, at end. If none, issue `All checks successful'. Output
2985 `Checking' instead of `Input file:'.
2987 * checks/get_them, checks/check_them: Reindented.
2989 * Makefile.in (dist): chmod a+r before making the tar file.
2991 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
2993 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
2995 * input.c (next_token): Reinitialize token_buttom just after using
2996 it as a watermark with obstack_free. Or else, a future token, big
2997 enough for triggering reallocation of the obstack chunk, could
2998 void the initialized value of token_buttom, later causing panic in
2999 obstack_free. Rename token_buttom to token_bottom everywhere.
3001 * m4.h: Before declaring errno, first include <errno.h> and
3002 ensure that it does not define errno.
3003 Reported by Richard Stallman.
3005 Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule)
3007 * builtin.c: Define and use DECLARE macro for builtins.
3009 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
3010 argument, this is a common idiom for introducing long comments.
3012 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
3013 arguments. The last argument was silently ignored.
3015 * m4.c (cmd_error): Add a missing semicolon before va_end().
