1082 in all files from `59 Temple Place, Suite 330, MA 02111-1307' to
1083 `51 Franklin Street, Fifth Floor, MA 02110-1301'.
1085 Also, some of the files here were never updated from the previous
1086 '675 Mass Ave, Cambridge, MA 02139', so changed those to the
1087 '51 Franklin Street, Fifth Floor, MA 02110-1301' address too.
1089 2005-03-31 Mike Frysinger <vapier@gentoo.org>
1091 * Makefile.in (bindir, infodir): Substitute from configure rather
1093 * doc/Makefile.in (infodir): Ditto.
1094 * src/Makefile.in (bindir): Ditto.
1097 2005-03-31 Gary V. Vaughan <gary@gnu.org>
1099 Changes needed to automate the release process for 1.4.3:
1101 * Makefile.in (dist): Make .tar.bz2 tarball too.
1102 * Makefile.maint (TSDEPS_DIST): Remove m4/libtool.m4.
1103 (cvs-news): Look 1 line further down for NEWS release number.
1104 (cvs-dist): We don't use automake, so make dist is fine.
1105 Remove double . before suffixes.
1106 (cvs-release): Don't mention manual.html.
1107 (fetch): Get latest gendocs files.
1108 (web-manual): Rewritten to use gendoc for multiformat manuals.
1109 * doc/gendocs.sh: Don't save an old version in m4 CVS!
1110 * doc/m4.texinfo (Index): HFS+ (the file system on my Mac) is case
1111 preserving, but case insensitive, so generating html docs per node
1112 clashes between Index.html, the node file, and index.html, the
1113 top-level of the document tree...
1114 (Index macro): ...so renamed to this. Changed all references.

1137 checks/47.patsubst, with a redundant @comment to prevent emacs
1138 from removing it accidentally again.
1139 * checks/get-them: Allow for trailing spaces tucked behind
1142 2005-03-31 Eric Blake <ebb9@byu.net> (tiny change)

1170 * src/freeze.c (produce_frozen_state): Use \n line-endings even
1171 on Windows, so that the frozen file reader will work.
1172 Reported by Josef T. Burger.
1174 * src/m4.c (main): Modernise the --version output.
1176 2005-02-03 Gary V. Vaughan <gary@gnu.org>
1178 Modernise the configury a little to prevent spurious errors from
1179 Autoconf-2.59's autoreconf:
1181 * config.h.in: Renamed to...
1182 * config-h.in: ...this to better support DOS 8.3 file systems.
1183 * acconfig.h: Removed.
1184 * configure.in: Renamed to...
1185 * configure.ac: ...this, and AC_DEFINE used to declare config.h
1186 entry comments. Slight reorganisation and reformatting.

1198 * src/freeze.c (produce_frozen_state), src/m4.c (main): Adjust for
1199 difference between PRODUCT="m4" and PACKAGE="GNU M4".
1200 * configure: Regenerated.
1202 2005-02-03 Noah Misch <noah@cs.caltech.edu>
1204 * src/output.c (mkstemp): Make non-static, and build regardless of
1205 HAVE_TMPFILE; src/builtin.c also needs this replacement.
1208 2004-09-09 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
1210 * configure.in (AC_CHECK_HEADERS): Commit works best when you save
1211 changes from your editor buffer first.
1213 * configure.in (AC_CHECK_HEADERS): Add signal.h, sys/signal.h.
1214 * src/m4.c: And include them as appropriate.
1217 2004-09-09 Andreas Schwab <schwab@suse.de>

1220 20% speedup of M4 as typically used by autoconf:
1222 * src/input.c (next_char_1): Renamed from next_char.
1223 (next_char): New macro.

1241 * src/path.c (path_search): Don't let "free" trash errno when
1243 * src/output.c (insert_file): Don't assume errno has a valid
1244 value simply because fread returns zero. This fixes a
1245 portability bug reported by Marion Hakanson in
1246 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
1248 2004-06-09 Gary V. Vaughan <gary@gnu.org>

1293 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
1294 empty file rather than to a nonexistent file. This closes a common
1296 * src/builtin.c (m4_maketemp): Implement the above, by using

1314 be opened, return immediately after producing the error message.
1315 Reported by Andreas Schwab.

1323 * src/macro.c (collect_arguments): Cast obstack arguments to
1324 (voidstar), so avoiding compiler warnings.
1325 Reported by Joseph E. Sacco.
1327 * src/freeze.c (produce_frozen_state): Cast printed lengths to

1329 Reported by Joseph E. Sacco.
1331 * src/m4.c (main): Cast the argument to xfree to (voidstar).
1332 * src/symtab.c (free_symbol): Idem.

1346 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
1347 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
1348 defines __STDC__ to 0, for indicating it is *not* ANSI!

1364 * aclocal.m4 (fp_C_PROTOTYPES): Substitute empty or ansi2knr for
1365 ANSI2KNR, depending on the fact the compiler is ANSI or not.
1366 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
1367 Remove the sed filter after ansi2knr for debug.c. Use $O instead
1368 of $U, put underline in extensions rather than in basenames. Use
1369 implicit rules, now that regularity makes this possible.
1370 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
1371 of ansi2knr whenever it is needed.
1372 * configure.in: Adjusted for correct STACKOVF substitution.
1373 * src/debug.c (trace_format): When not __STDC__, use (...) as a
1374 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.

1387 * Makefile.in: For actions invoking $(MAKE) from within compound
1388 sh statements, exit non-zero if the sub-make fails. Otherwise,
1389 the top-level make may exit successfully when it should fail.
1390 Reported by Jim Kingdon.
1392 * {,/*}Makefile.in: Use && after all cd, in case they fail.
1394 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.
1395 (dist): Use PRODUCT and VERSION instead of tricks on .fname.
1396 * configure.in: Substitute PRODUCT and VERSION.

1400 Thu Oct 27 22:32:58 1994 Francois Pinard (pinard@icule)
1402 * Makefile.in (mostlyclean-local): Do not remove *~.
1403 * */Makefile.in (mostlyclean): Idem.

1426 (setup_stackovf_trap): Use RETSIGTYPE instead of void while
1427 casting sigsegv_handler.
1428 Reported by Robert Bernstein.

1453 (realclean): Remove it.
1454 * Makefile.in: Make TAGS in lib also, not just in src.
1455 Reported by Karl Berry.
1457 * Makefile.in (distclean, realclean): Instead of recursively
1458 calling $(MAKE) for the -local part, allow parallel execution of
1459 -recursive and -local, only delay the removal of config.status,
1460 which is repeated in both goals.
1462 Tue Sep 13 19:21:05 1994 Francois Pinard (pinard@icule)
1466 * Makefile.in: Group all *clean-recursive goals in one, using sed
1467 to remove `-recursive' while calling make recursively. Also, use
1468 a subshell for each recursive $(MAKE).
1469 Reported by Jim Meyering.
1471 * src/m4.h (memcpy): Define with bcopy for BSD systems.
1472 Reported by Kaveh R. Ghazi.
1474 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
1475 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
1478 * configure.in: Use date instead of touch for stamp-h.
1479 * Makefile.in (stamp-h.in): Idem.
1481 * Makefile.in (distclean, realclean): Force serial execution of
1482 both goals, in case parallel makes are being used.

1514 care of systems having only incomplete implementations (like for
1515 Pyramid 9820 OSx 5.0d).
1516 Reported by Kaveh R. Ghazi.

1535 * src/m4.h: Adjust declaration for prefix_all_buitins.
1536 * src/builtin.c (builtin_init): Merge in functionality from
1537 previous prefix_all_buitins function, while making entries in the
1538 symbol table, but not modifying the builtin description itself.
1540 * src/freeze.c (reload_frozen_state): Add a useless `break;',
1541 because *many* compilers do not accept an empty `default:'.
1542 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
1543 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
1545 * configure.in: Use AC_TYPE_SIGNAL.

1556 a per buffer MAXIMUM_BUFFER_SIZE.
1558 * src/output.c (output_text): New function, for optimizing the

1571 beginning for the eventual withdrawal of NUL terminated strings.)
1572 * output.c (shipout_text): Accept a length parameter, and use it.
1573 All callers adjusted.
1575 Mon Aug 29 12:27:19 1994 Francois Pinard (pinard@icule)

1600 freeze_diversions to add diversions to frozen format, and code to
1601 reload them properly.
1602 * m4.c: Do not undivert automatically at end when status being
1603 frozen. Do not call builtin_init when reloading frozen state.
1605 Speed up diversion processing:
1606 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
1607 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion

1617 * Makefile.in, lib/Makefile.in, checks/Makefile.in: Arrange so
1618 dist works from another build directory.
1620 Sat Aug 27 14:32:45 1994 Francois Pinard (pinard@icule)
1622 * symtab.c (hack_all_symbols): Use hash_table_size instead of
1623 constant HASHMAX, for -H option to work better.
1625 * builtin.c (DECLARE): Simplify by using _ ().
1627 * freeze.c: New file.
1628 * Makefile.in: Compile it, distribute it.
1629 * m4.c: Recognize, document and process --freeze-state (-F) and
1630 --reload-state (-R) options. Pass a true flag to builtin_init
1631 only if no reloading some state.
1632 * builtin.c (define_builtin): Remove static specifier.
1633 (find_builtin_by_name): Remove static specifier.
1634 (builtin_init): Accept and obey a flag argument.

1643 * acconfig.h: Document WITH_DMALLOC.
1644 * m4.h: Add code for when WITH_DMALLOC.
1646 Mon Aug 15 12:38:05 1994 Francois Pinard (pinard@icule)
1648 * m4.c (long_options): Use "error-output", the dash was missing.
1649 Reported by Akiko Matsushita.
1651 Fri Aug 12 16:38:01 1994 Francois Pinard (pinard@icule)
1653 * m4.h: Include <sys/types.h>.
1654 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
1655 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
1657 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
1659 * builtin.c (dump_args): Declare len as size_t, not int.
1661 * debug.c: Prototype the forward declaration of debug_set_file.
1663 * builtin.c (m4_undivert): Replace div by file, for avoiding the
1664 shadowing of this variable.
1665 * output.c (insert_diversion): Idem.
1667 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
1668 (input_init): Duplicate default quote and comment strings.
1669 (set_quotes): Free previous quote strings in all cases. Duplicate
1670 even default quote strings.
1671 (set_comment): Free previous comment strings in all cases.
1672 Duplicate even default comment strings.
1674 * configure.in: Updated for Autoconf 2.0.
1675 * Makefile.in (distclean-local): Also delete config.cache.
1677 * m4.c (usage): Reorganize the --help output by topic. Include a
1678 description for debugging flags.
1680 Fri Jul 29 10:15:52 1994 Francois Pinard (pinard@icule)
1682 * configure.in: If sigaction is available and SA_ONSTACK defined,
1683 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
1684 defined, use sigvec. Else don't compile stackovf.c.
1685 * stackovf.c (setup_stackovf_trap): Idem.
1686 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
1689 Thu Jul 21 22:43:17 1994 Francois Pinard (pinard@icule)
1691 * m4.c (usage): Replace printf par fputs.
1693 Mon Jul 18 23:48:23 1994 Francois Pinard (pinard@icule)
1697 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
1699 * configure.in: Check for sigaction and sigvec. Add a new delayed
1700 check for RLIMIT_STACK, combine in the checking for getrlimit.
1701 All those things are not universally available.
1702 * stackovf.c: Split setting up the trap handler and catching
1703 signals, for better taking care of various configure outcomes.
1704 * examples/stackovf.sh: Correct a typo.
1705 Reported by Eric Backus, Jim Avera and Jim Meyering.
1707 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)
1709 * ansi2knr.c: New version sent by its author, Peter Deutsch.
1711 Fri Jul 15 14:36:21 1994 Francois Pinard (pinard@icule)
1713 * Makefile.in: Modify so parallel make will not try making
1714 lib/libm4.a twice simultaneously.
1715 Reported by Jim Meyering.
1717 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
1719 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
1720 error message, for when no code possibility exists. Even if this
1721 line is completely #ifdef'ed out, it brings a syntax error.
1722 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
1724 * Makefile.in (install): Have install depend on all too, for lib
1725 to be remade as needed.
1727 * examples/stackovf.sh: Try ksh, bsh and bash for shells
1728 providing ulimit, instead of using only ksh.
1729 Reported by Jim Avera and Joseph E. Sacco.
1731 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
1733 * Makefile.in (check): Have it depend on all instead of m4. In
1734 this way, a change in lib will be detected and processed.
1736 * builtin.c (numeric_arg): Use strtol and verify the conversion,
1737 instead of using sscanf which stops as soon as there is a
1738 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
1739 and divert(1xyzzy) were all accepted without any warning or error
1741 * m4.h: Declare strtol as long if not including stdlib.h.
1742 * configure.in: Check for limits.h, and replace strtol if missing.
1743 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
1744 * lib/strtol.c: New file, from elsewhere.
1745 Reported by Andreas Schwab.
1747 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
1749 * macro.c (expand_macro): Cast value to (boolean) prior to
1750 assigning it to traced.
1751 Reported by Tom McConnell.
1753 * Makefile.in (m4): Always make all in lib first.
1754 Reported by Jim Meyering.
1756 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
1758 * stackovf.c: Isolated OS-dependent sections; Improved portability,
1759 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
1760 handlers), and a default error message if the fault address is not
1761 available (when neither siginfo.h nor BSD sigcontext are supported).
1762 * configure.in: Changes for stackovf.h: Check for sigcontext,
1763 sigaction, sigstack, and define rlim_t as int if necessary.
1764 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
1765 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
1766 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
1768 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
1770 * configure.in: Use AC_SET_MAKE.
1771 * Makefile.in: Use @SET_MAKE@.
1772 Reported by Jim Meyering.
1774 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
1775 Reported by Ian Taylor.
1777 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
1779 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
1780 because siginfo.h is unrelated to standard headers, and siginfo.h
1781 is already checked for.
1782 Reported by Joseph E. Sacco.
1784 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
1786 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
1789 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
1791 * builtin.c (substitute): Use \& to represent this part of the
1792 string which was matched by the whole regexp, instead of
1793 representing the whole string. Any usage of \0 issues a warning
1794 and acts like \&, it will disappear in some subsequent release.
1796 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
1798 * m4.c: Complete prototype for forwarded declaration of usage.
1800 * input.c (init_macro_token): Correct own reference in error
1801 message. Previous name get_macro_func was referred to instead.
1802 (next_char): Correct own reference in error message. Previous
1803 name advance_input was referred to instead.
1805 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
1806 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
1807 and_term, not_term, logical_not_term, cmp_term, shift_term,
1808 add_term, mult_term, exp_term, unary_term, simple_term): Add
1809 prototype to forwarded declarations. Declare parameter v1 as
1810 eval_t * instead of int *. Same for local variable v2 in dyadic
1811 functions. Same for result in exp_term.
1812 * builtin.c (m4_eval): Declare value as eval_t instead of int.
1813 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
1814 unsigned_eval_t instead of unsigned int. Change casts accordingly.
1815 (shipout_int): Cast first argument of ntoa to eval_t.
1816 Reported by Thorsten Ohl.
1818 * macro.c: Complete the prototypes of forwarded expand_macro and
1820 Reported by Thorsten Ohl.
1822 * m4.h: Define voidstar as void * or char * depending on __STDC__.
1823 The Ultrix 3.1 compiler cannot do much with void pointers.
1825 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
1826 * m4.c (xfree): Replace void * by voidstar.
1827 Reported by Tom McConnell.
1829 * ansi2knr.1: New, from elsewhere.
1830 * Makefile.in (DISTFILES): Distribute ansi2knr.1
1832 * Makefile.in (stamp-h.in): Avoid running ./config.status if
1833 stamp-h does not exist yet. This avoids running it a second time
1834 just after the initial ./configure.
1835 Reported by David MacKenzie and Tom McConnell.
1837 * m4.h: Replace the enum debug_info declaration with a series of
1838 #define's. The Ultrix 3.1 compiler would otherwise need casting
1839 (int) to most references, when used in expressions.
1840 Reported by Tom McConnell.
1842 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
1844 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
1845 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
1846 calls the compiler. Previously, FP_PROTOTYPES was only calling
1847 the preprocessor; by not being subject to CFLAGS, this was
1848 discouraging those flags asking for ANSI compilation.
1849 * acconfig.h: Document HAVE_PROTOTYPES.
1850 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
1851 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
1852 Reported by Eric Backus.
1854 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
1855 from the environment. Default CFLAGS to -g if not set.
1856 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
1857 * lib/Makefile.in: Have CFLAGS substituted from configure.
1858 Reported by Eric Backus and Tom McConnell.
1860 * configure.in: m4_undefine changeword before using AC_ENABLE.
1862 * m4.h: Declare prototypes for error (for ANSI compilers only),
1863 prefix_all_builtins and reference_error.
1864 Reported by Tom McConnell.
1866 * input.c (set_word_regexp): Do not try to initialize the array
1867 test from a string, this does not work with non-ANSI compilers.
1868 Reported by Eric Backus.
1870 * Makefile.in (dist): Clean examples/ before saving it.
1871 (distclean-local): Also remove stamp-h.
1872 Reported by Eric Backus.
1874 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
1876 Reported by Tom McConnell.
1878 * checks/Makefile.in (clean): Depends on mostlyclean.
1879 (mostlyclean): New goal.
1881 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
1883 * Makefile.in (DISTFILES): Distribute install.sh.
1884 * install.sh: New file, copied from elsewhere.
1885 Reported by Assar Westerlund and Kaveh R. Ghazi.
1887 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
1889 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
1890 * acconfig.h: Explain ENABLE_CHANGEWORD.
1892 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
1893 from code provided by Pete Chown]
1894 * m4.h: Add original_text field to u_t variant of union u.
1895 Declare TOKEN_DATA_FUNC macro.
1896 * builtin.c: Declare changeword.
1897 (m4_changeword): New function.
1898 * input.c: Include "regex.h", define variables with word regexps.
1899 (input_init): Initialize the word regexp.
1900 (set_word_regexp): New.
1901 (next_token): Declare local variables, use the previous code if
1902 default_word_regexp is true. Else, match using a new code. Save
1904 * macro.c (expand_token): Ship out original text if not a macro
1906 Reported by Krste Asanovic and Pete Chown.
1908 [These modifs all depend upon ENABLE_CHANGEWORD]
1909 * m4.h: Declare external user_word_regexp.
1910 * m4.c: Declare user_word_regexp, and initialize it from
1911 --word-regexp or -W, or NULL if not specified.
1912 * input.c: Use user_word_regexp if specified, instead of
1913 DEFAULT_WORD_REGEXP.
1915 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
1918 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
1919 * checks/Makefile.in: Empty the suffix list.
1920 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
1922 * m4.c: Declare nesting_limit and initialize it to 250.
1923 Implement -LNUMBER or --nesting-limit=NUMBER to change its
1925 * m4.h: Declare nesting_limit as external.
1926 * macro.c (expand_macro): Stop execution whenever nesting limit
1928 Reported by Bengt Mertensson.
1930 * eval.c (evaluate): Diagnose excess characters in eval input.
1931 Things like `eval(08)' used to return 0 with no diagnostic.
1933 * m4.h: Capitalize first letter of all macro arguments in
1936 * m4.c: Declare warning_status, initialize it to 0. Add new
1937 option -E, or --fatal-warnings, which sets warning_status to
1938 EXIT_FAILURE instead.
1939 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
1940 EXIT_FAILURE if not otherwise done by header files.
1941 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
1942 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
1943 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
1944 argument of all M4ERROR calls.
1945 Reported by Noah Friedman.
1947 * examples/incl-test.m4: Renamed from incl_test.m4.
1948 * examples/include.m4: Include incl-test.m4 instead of
1950 * examples/multiquotes.m4: Renamed from multi-quotes.m.
1952 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
1954 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
1955 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
1956 also tested it on a Sun Sparc workstation running SunOS 4.x.
1958 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
1959 49.format check, abusing a `union values' argument with sprintf
1960 without selecting the proper field. Now, save the formatting type
1961 first, delaying the fetch of the corresponding argument.
1962 Reported by Joseph E. Sacco and Tom Quinn.
1964 * format.c (format): Remove const from char *fmt declaration when
1965 not HAVE_EFGCVT, because a NUL may be forced into it.
1967 * m4.h: Declare atof() when not STDC_HEADERS.
1968 Reported by Joseph E. Sacco.
1970 * Regenerate configure using Autoconf 1.11, this corrects a
1971 problem about an incorrect cpp seting on NeXT 3.1.
1972 Reported by Alexander Lehmann.
1974 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
1976 * m4.h (_): Change argument from `x' to `Args'.
1978 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
1980 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
1981 bringing more evil than good on a few systems.
1982 Reported by Greg A. Woods.
1984 Fri Apr 22 15:59:35 1994 Francois Pinard (pinard@icule)
1986 * m4.h: Rename Args() to _().
1987 * m4.h: Remove extern specifier from all function declarations.
1989 Fri Apr 22 15:51:21 1994 Jim Avera (jima@netcom.com)
1991 * stackovf.c: New file implementing stack-overflow detection.
1992 * configure.in: Check for getrlimit, sigaction. If all of
1993 standard headers, getrlimit and sigaction, define USE_STACKOVF and
1994 substitute ${U}stackovf.o for STACKOVF.
1995 * acconfig.h: Declare USE_STACKOVF.
1996 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
1997 * m4.h: Declare setup_stackovf_trap().
1998 * m4.c: Call setup_stackovf_trap().
1999 * tests/stackovf_test.sh: New file.
2001 Wed Apr 13 14:10:30 1994 Francois Pinard (pinard@icule)
2003 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
2005 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
2007 Sun Jan 30 14:24:19 1994 (pinard at icule)
2009 * m4.h: Remove definition of volatile, not used anymore.
2010 Reported by Jim Meyering and Joseph E. Sacco.
2012 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
2013 of `if ... else /* nothing */' for if macros.
2014 Reported by Jim Meyering.
2016 * builtin.c (m4_regexp): Reorganize the code for avoiding a
2017 warning from gcc about `repl' possibly used before defined.
2018 Reported by Jim Meyering.
2020 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
2021 Reported by Jim Meyering.
2023 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
2025 * m4.h: Move the conditional definition of volatile after the
2026 inclusion of system files, because they may define it first.
2028 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
2030 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
2031 get around a problem with Alpha make seeing a syntax error, there.
2032 Reported by Vern Paxson.
2034 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
2036 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
2037 Reported by Richard Stallman.
2039 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)
2041 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
2042 instead of AC_HAVE_FUNCS.
2043 Reported by Noah Friedman.
2045 Wed Dec 1 09:37:53 1993 Francois Pinard (pinard@icule)
2047 * m4.c: Initialize show_help and show_version to zero.
2049 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
2050 Use them in exit() and usage() calls.
2052 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
2054 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
2055 syserr() macro. Delete errref, add reference_error and M4ERROR.
2056 * m4.c: Replace errref, which was returning an input reference
2057 string, with reference_error, which prints it on standard error.
2058 * builtin.c, output.c: Use errno as second parameter to error,
2059 instead of using syserr() with %s.
2060 * *.c: Use M4ERROR instead of error: no more errref() with %s.
2061 Doing so, the program name appears after the input reference
2062 instead of before, which eases M-x next-error processing.
2064 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
2066 * checks/get-them: Escape braces with backslashes in patterns,
2067 because HPUX-9.01 awk needs this.
2068 Reported by Jim Meyering.
2070 Mon Nov 22 10:55:52 1993 Francois Pinard (pinard@icule)
2072 * builtin.c: Declare "FILE *popen ();".
2074 * m4.h: Remove MESSAGE{,1,2}, WARNING1, FATAL{,1}, INTERNAL_ERROR
2075 macros, replace error_message_prefix() declaration by errref()'s.
2076 Declare xrealloc, for use in errref().
2077 * m4.c: Delete error_message_prefix() function, add errref().
2078 * *.c: Use error() systematically in place of all error macros,
2079 now that error() flushes stdout first. Make needed adjustments.
2081 * m4.h: Remove const in sys_errlist[] declaration, it creates
2082 conflicts on SGI and Alpha.
2083 Reported by Kaveh R. Ghazi.
2085 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)
2087 * m4.c: Include <getopt.h> instead of "getopt.h".
2089 * configure.in: Output to config.h. Use HAVE_FUNCS preferably.
2090 * acconfig.h: New, for documenting HAVE_EFGCVT.
2091 * Makefile.in: Distribute acconfig.h, .stamp-h.in and config.h.in,
2092 use them wherever appropriate. Also use -I. for compilations.
2093 * lib/Makefile.in: Use -I.. for compilations.
2094 * *.c: Include <config.h> or "config.h".
2096 * m4.h: Test for HAVE_MEMORY_H instead of NEED_MEMORY_H.
2097 * configure.in: Use AC_HAVE_HEADERS(memory.h), delete AC_MEMORY_H.
2099 Wed Nov 17 09:34:55 1993 Francois Pinard (pinard@icule)
2101 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
2103 * input.c (input_init): Initialize quote and comment strings
2104 explicitely instead of calling set_quotes and set_comment: by
2105 doing so, we ensure we do not free uninitialized variables.
2107 * checks/check-them: Reverse arguments to both diff, so the
2108 expected is on the left and the obtained on the right.
2110 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
2111 macros. Delete declarations for m4error, warning, fatal and
2112 internal_error, add declaration for error_message_prefix.
2113 * m4.c: Delete m4error, warning, fatal and internal_error
2114 routines, add error_message_prefix routine.
2115 * *.c: Replace m4error routine calls with MESSAGE* macro calls,

2394 macro.c, output.c, path.c, symtab.c: Change Copyright from
2395 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.
2397 * examples/divert.m4: Deleted, this bug has been corrected.

2401 * Makefile.in (clean): Remove clutter from ansi2knr.
2402 Reported by Pierre Gaumond.

2418 Sat Dec 19 08:21:34 1992 Francois Pinard (pinard at icule)
2421 This is still a beta release for the future GNU m4 version 1.1.
2423 * lib/alloca.c: New, from elsewhere.
2424 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
2426 * m4.h: Do not define index/rindex if already defined. If
2427 FALSE/TRUE are already defined, do not redefine them, but merely
2428 define boolean typedef to int.
2430 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
2431 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
2432 because some C compilers do not like connectives with #ifdef.
2433 * m4.h: Define `volatile' only if __GNUC__, instead of once for
2434 __GNUC__ and once for __STDC__.
2435 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
2437 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
2438 Makefile dependencies. Without it, make keeps destroying and
2439 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
2441 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
2442 to diversion/DIVERSION, this was a spelling error.
2444 * m4.c: Declare version[], remove #include "version.h".
2445 * version.h: Deleted.
2446 * Makefile.in: Remove references to version.h.
2448 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
2449 production, by using a simpler and more robust algorithm. This
2450 solves the problem of synclines sometimes written in the middle of
2451 an output line. Delete sync_line() and output_lines variable.
2452 * m4.h: Remove sync_line prototype and output_lines declaration.
2453 * input.c (next_char), output.c (shipout_text): Remove references
2455 * input.c (push_file, pop_file): Merely put the value -1 in
2456 output_current_line instead of calling sync_line, for delaying a
2457 single `#line NUM FILE' before next output line. Do not test
2458 for sync_output, because this is unnecessary clutter.
2459 * output.c (make_divertion, insert_divertion): Idem.
2460 * input.c: Rename must_advance_line to start_of_input_line, for
2463 * debug.c (trace_header): Select a new debug line format, which
2464 better complies with GNU standards for formatting error messages.
2465 With option `-dfl', M-x next-error might be used on the output.
2466 * m4.c (vmesg): Adjust format of error output to GNU standards.
2467 * m4.texinfo: Adjust examples for `make check' to work.
2469 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
2470 case for enum debug_info constants, which were all lower case.
2472 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
2474 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
2475 collected patches. I tried a few times using newer regex.[ch], it
2476 mysteriously stopped aborting with this one. Insecure feeling...
2477 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
2479 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
2481 * m4.c: Change `--no-warnings' to `--silent'.
2482 Reported by David MacKenzie.
2484 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
2485 leave it off for now. See comment in m4.c for justification.
2486 Reported by David MacKenzie.
2488 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
2489 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
2491 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
2493 * Makefile.in: Ensure recursive cleaning is done before local
2494 cleaning for all clean goals.
2496 * builtin.c (ntoa): Ensure the value is always interpreted as a
2497 signed quantity, whatever the radix is.
2499 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
2501 * builtin.c, format.c, input.c: Split long lines.
2502 * m4.c: Use typedef macro_definition instead of struct
2504 * symtab.c: Use typedef symbol instead of struct symbol.
2506 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
2508 * *.[ch]: Remove all trailing whitespace, in code and comments.
2510 * configure.in: Find some awk.
2511 * Makefile.in: Add $(AWK) to MDEFINES.
2512 * checks/Makefile.in: Transmit $(AWK) to get_them.
2513 * checks/get_them: Use $AWK instead of gawk. Add a close in the
2514 awk script when switching files, because without this, mawk runs
2515 out of file descriptors.
2517 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
2519 * Makefile.in (realclean): Delete m4.info*.
2520 Reported by Jim Meyering.
2522 * Makefile.in: Adjust and link with checks/Makefile.
2523 * checks/Makefile.in: New.
2524 * configure.in: Output checks/Makefile.
2526 * checks/get_them: Have the dnl header of each test more
2527 recognizable by next-error, also use a better message.
2529 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
2531 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
2532 And use that only if __GNUC__ since we're using it's GCC-specific
2533 semantics that tell the compiler the associated function doesn't
2536 * builtin.c (substitute): Don't use character as an array index.
2537 (dumpdef_cmp): Make formal arguments `const void *' to avoid
2538 warnings with gcc -W -Wall on systems with qsort prototype.
2539 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
2542 * eval.c (most functions): Add parentheses to assignments used
2543 as truth values go avoid warnings from gcc -Wall.
2545 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
2546 any functions that don't need external scope.
2548 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
2549 (many functions and arrays): Declare `const'.
2551 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
2553 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
2554 removing the declaration from m4.h. Also rename false to FALSE
2557 * lib/Makefile.in (Makefile): New goal.
2559 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
2560 so heavily loaded. It gets more easily overridable, calling make.
2561 Reported by Jim Meyering.
2563 * Makefile.in (dist): Get .fname from the current directory name,
2564 instead of from version.h. I need updating many files manually,
2565 when the version changes, version.h is just one of them.
2567 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
2569 * m4.h: Remove the tag `boolean' on the enum introducing typedef
2570 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
2571 Reported by Tom McConnell.
2573 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
2575 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
2576 39.cleardiv, which were describing missing or spurious newlines.
2577 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
2578 do not depend on machine word size, `/bin/false' implementation,
2579 or `wc' output format. `make check' is more dependable, now.
2581 * checks/check_them: Summarize the failed tests by listing their
2582 name, at end. If none, issue `All checks successful'. Output
2583 `Checking' instead of `Input file:'.
2585 * checks/get_them, checks/check_them: Reindented.
2587 * Makefile.in (dist): chmod a+r before making the tar file.
2589 Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
2591 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
2593 * input.c (next_token): Reinitialize token_buttom just after using
2594 it as a watermark with obstack_free. Or else, a future token, big
2595 enough for triggering reallocation of the obstack chunk, could
2596 void the initialized value of token_buttom, later causing panic in
2597 obstack_free. Rename token_buttom to token_bottom everywhere.
2599 * m4.h: Before declaring errno, first include <errno.h> and
2600 ensure that it does not define errno.
2601 Reported by Richard Stallman.
2603 Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule)
2605 * builtin.c: Define and use DECLARE macro for builtins.
2607 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
2608 argument, this is a common idiom for introducing long comments.
2610 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
2611 arguments. The last argument was silently ignored.
2613 * m4.c (cmd_error): Add a missing semicolon before va_end().
2615 Tue Nov 10 08:57:05 1992 Francois Pinard (pinard at icule)
2617 * Makefile.in: Now handle protoized sources. Define and use U.
2618 Compile and use ansi2knr with old compilers. Update DISTFILES.
2619 Add `aclocal.m4' to `configure' dependencies.
2620 * ansi2knr.c: New, from Ghostscript distribution.
2621 * configure.in: Define U through FP_PROTOTYPES for old compilers.
2622 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
2623 * aclocal.m4: New, provide FP_PROTOTYPES.
2624 * m4.h: Conditionnaly protoized through Args, save for varags.
2625 * builtin.c: Protoized. Then:
2626 Include <sys/types.h> if size_t is not defined, before "regex.h".
2627 (m4_ifelse): Fetch built-in name properly for diagnostic.
2628 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
2629 (m4_regexp): Add const to `msg' declaration.
