1507 2005-10-17 John Gatewood Ham <zappaman@buraphalinux.org> (tiny change)
1509 * README: update email address for bug reports.
1511 2005-10-17 Gary V. Vaughan <gary@gnu.org>
1513 * doc/m4.info: Generated files are not kept in the repository.
1515 2005-05-01 Gary V. Vaughan <gary@gnu.org>
1517 The FSF are moving offices today. Changed their contact address
1518 in all files from `59 Temple Place, Suite 330, MA 02111-1307' to
1519 `51 Franklin Street, Fifth Floor, MA 02110-1301'.
1521 Also, some of the files here were never updated from the previous
1522 '675 Mass Ave, Cambridge, MA 02139', so changed those to the
1523 '51 Franklin Street, Fifth Floor, MA 02110-1301' address too.
1525 2005-03-31 Mike Frysinger <vapier@gentoo.org>
1527 * Makefile.in (bindir, infodir): Substitute from configure rather
1528 than hardcode.
1529 * doc/Makefile.in (infodir): Ditto.
1530 * src/Makefile.in (bindir): Ditto.
1531 * NEWS: Updated.
1533 2005-03-31 Gary V. Vaughan <gary@gnu.org>
1535 Changes needed to automate the release process for 1.4.3:
1537 * Makefile.in (dist): Make .tar.bz2 tarball too.
1538 * Makefile.maint (TSDEPS_DIST): Remove m4/libtool.m4.
1539 (cvs-news): Look 1 line further down for NEWS release number.
1540 (cvs-dist): We don't use automake, so make dist is fine.
1541 Remove double . before suffixes.
1542 (cvs-release): Don't mention manual.html.
1543 (fetch): Get latest gendocs files.
1544 (web-manual): Rewritten to use gendoc for multiformat manuals.
1545 * doc/gendocs.sh: Don't save an old version in m4 CVS!
1546 * doc/m4.texinfo (Index): HFS+ (the file system on my Mac) is case
1547 preserving, but case insensitive, so generating html docs per node
1548 clashes between Index.html, the node file, and index.html, the
1549 top-level of the document tree...
1550 (Index macro): ...so renamed to this. Changed all references.
1552 2005-03-31 Gary V. Vaughan <gary@gnu.org> (tiny change)

1568 canonical versions.
1570 2005-03-31 Eric Blake <ebb9@byu.net> (tiny change)
1572 * doc/m4.texinfo (Patsubst): Re-add trailing space required by
1573 checks/47.patsubst, with a redundant @comment to prevent emacs
1574 from removing it accidentally again.
1575 * checks/get-them: Allow for trailing spaces tucked behind
1576 @comment marks.
1578 2005-03-31 Eric Blake <ebb9@byu.net> (tiny change)

1604 * src/m4.h (__CYGWIN__, WIN32): Canonicalise Windows and Cygwin
1605 recognition macros.
1606 * src/freeze.c (produce_frozen_state): Use \n line-endings even
1607 on Windows, so that the frozen file reader will work.
1608 Reported by Josef T. Burger.
1610 * src/m4.c (main): Modernise the --version output.
1612 2005-02-03 Gary V. Vaughan <gary@gnu.org>
1614 Modernise the configury a little to prevent spurious errors from
1615 Autoconf-2.59's autoreconf:
1617 * config.h.in: Renamed to...
1618 * config-h.in: ...this to better support DOS 8.3 file systems.
1619 * acconfig.h: Removed.
1620 * configure.in: Renamed to...
1621 * configure.ac: ...this, and AC_DEFINE used to declare config.h
1622 entry comments. Slight reorganisation and reformatting.
1623 * aclocal.m4: Use third argument to AC_DEFINE to declare config.h
1624 entry comments.
1625 (AC_INIT): Use a modern 3 argument call.

1627 examples/Makefile.in, lib/Makefile.in, src/Makefile.in:
1628 s/PRODUCT/PACKAGE/g.
1629 * Makefile.in (DISTFILES): Removed acconfig.h, configure.in,
1630 config.h.in. Added configure.ac, config-h.in.
1631 (stamp-h.in): Removed acconfig.h from dependencies.
1632 (configure): Depends on configure.ac, not configure.in.
1633 * doc/Makefile.in (stamp-vti): Ditto.
1634 * src/freeze.c (produce_frozen_state), src/m4.c (main): Adjust for
1635 difference between PRODUCT="m4" and PACKAGE="GNU M4".
1636 * configure: Regenerated.
1638 2005-02-03 Noah Misch <noah@cs.caltech.edu>
1640 * src/output.c (mkstemp): Make non-static, and build regardless of
1641 HAVE_TMPFILE; src/builtin.c also needs this replacement.
1642 * NEWS: Update.
1644 2004-09-09 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
1646 * configure.in (AC_CHECK_HEADERS): Commit works best when you save
1647 changes from your editor buffer first.
1649 * configure.in (AC_CHECK_HEADERS): Add signal.h, sys/signal.h.
1650 * src/m4.c: And include them as appropriate.
1651 * NEWS: Updated.
1653 2004-09-09 Andreas Schwab <schwab@suse.de>
1655 Refactoring of the string read case in next_char provides about a
1656 20% speedup of M4 as typically used by autoconf:

1670 * configure.in (VERSION): Bump to 1.4.2.
1671 * News: Describe 1.4.2's changes.
1673 * src/m4.c (reference_error): Preserve errno, since M4ERROR
1674 relies on this.
1675 * src/builtin.c (m4_esyscmd): Clear errno before calling popen.
1676 (m4_maketemp): Clear errno before calling mkstemp.
1677 * src/path.c (path_search): Don't let "free" trash errno when
1678 returning NULL.
1679 * src/output.c (insert_file): Don't assume errno has a valid
1680 value simply because fread returns zero. This fixes a
1681 portability bug reported by Marion Hakanson in
1682 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
1684 2004-06-09 Gary V. Vaughan <gary@gnu.org>

1700 to pacify Texinfo 4.7.
1701 * doc/Makefile.in (info): Remove info-1, info-2, info-3.
1703 * src/m4.h, src/debug.c: Use #ifdef __STDC__, not #if __STDC__, to
1704 pacify Sun C compilers.
1706 2003-09-28 Akim Demaille <akim@epita.fr>
1708 * src/symtab.c (lookup_symbol): Fix an uninitialized-variable

1726 2001-02-01 Matt Kraai <kraai@debian.org>
1728 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=84416
1729 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
1730 empty file rather than to a nonexistent file. This closes a common
1731 security hole.
1732 * src/builtin.c (m4_maketemp): Implement the above, by using
1733 mkstemp rather than mktemp. (trivial change)
1735 2000-01-09 Akim Demaille <demaille@inf.enst.fr>
1737 * src/builtin.c (expand_ranges): Added break after trailing dash.
1738 This caused misbehaviors on some systems.

1750 be opened, return immediately after producing the error message.
1751 Reported by Andreas Schwab.
1753 * configure.in: Check for const only after having found possible
1754 ANSIfying compiler flags, this is of no use to check it before.
1755 Reported by Alexander Lehmann.
1757 Tue Nov 1 22:02:37 1994 Francois Pinard (pinard@icule)
1759 * src/macro.c (collect_arguments): Cast obstack arguments to
1760 (voidstar), so avoiding compiler warnings.
1761 Reported by Joseph E. Sacco.
1763 * src/freeze.c (produce_frozen_state): Cast printed lengths to
1764 (int) so they correspond to %d format items.
1765 Reported by Joseph E. Sacco.
1767 * src/m4.c (main): Cast the argument to xfree to (voidstar).
1768 * src/symtab.c (free_symbol): Idem.
1769 Reported by Karl Vogel.
1771 Mon Oct 31 02:11:19 1994 Francois Pinard (pinard@icule)

1780 Sun Oct 30 08:13:03 1994 Francois Pinard (pinard@icule)
1782 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
1783 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
1784 defines __STDC__ to 0, for indicating it is *not* ANSI!
1785 Reported by Kaveh R. Ghazi.
1787 * configure.in: Added obsolescent tests for AIX and Minix.
1789 * doc/Makefile.in (mostlyclean): Remove texclean in dependencies,
1790 which texclean does not exist anymore.
1791 Reported by Eric Backus, Jim Meyering, John David Anglin and
1792 Joseph E. Sacco.

1799 * src/ansi2knr.c: New version, sent by Peter Deutsch.
1800 * aclocal.m4 (fp_C_PROTOTYPES): Substitute empty or ansi2knr for
1801 ANSI2KNR, depending on the fact the compiler is ANSI or not.
1802 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
1803 Remove the sed filter after ansi2knr for debug.c. Use $O instead
1804 of $U, put underline in extensions rather than in basenames. Use
1805 implicit rules, now that regularity makes this possible.
1806 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
1807 of ansi2knr whenever it is needed.
1808 * configure.in: Adjusted for correct STACKOVF substitution.
1809 * src/debug.c (trace_format): When not __STDC__, use (...) as a
1810 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.
1811 Reported by David MacKenzie.
1813 * Makefile.in: Remove binprefix. Use transform_name instead.
1814 Reported by David MacKenzie.
1816 * doc/Makefile.in: Create version.texi, use it, clean it.

1821 * Makefile.in (all, install, uninstall): Depend on Makefile.
1823 * Makefile.in: For actions invoking $(MAKE) from within compound
1824 sh statements, exit non-zero if the sub-make fails. Otherwise,
1825 the top-level make may exit successfully when it should fail.
1826 Reported by Jim Kingdon.
1828 * {,/*}Makefile.in: Use && after all cd, in case they fail.
1830 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.
1831 (dist): Use PRODUCT and VERSION instead of tricks on .fname.
1832 * configure.in: Substitute PRODUCT and VERSION.
1834 * {,*/}Makefile.in (dist): Always try a hard link before a copy.
1836 Thu Oct 27 22:32:58 1994 Francois Pinard (pinard@icule)
1838 * Makefile.in (mostlyclean-local): Do not remove *~.
1839 * */Makefile.in (mostlyclean): Idem.
1840 Reported by Robert E. Brown and Richard Stallman.
1842 Sun Oct 9 08:30:13 1994 Francois Pinard (pinard@icule)

1850 Reported by David MacKenzie.
1852 Sat Oct 1 11:22:42 1994 Francois Pinard (pinard@icule)
1854 * configure.in: Do not add -O to CFLAGS for GNU C, now that
1855 configure does it automatically.
1856 Reported by Jim Meyering.
1858 Fri Sep 23 08:16:58 1994 Francois Pinard (pinard@icule)
1860 * src/stackovf.c: Declare the handler_t typedef earlier in the
1861 code, use it for stackovf_handler.
1862 (setup_stackovf_trap): Use RETSIGTYPE instead of void while
1863 casting sigsegv_handler.
1864 Reported by Robert Bernstein.
1866 * src/m4.c (main): Initialize program_name to argv[0] without
1867 basename'ing it.
1868 Reported by Karl Berry.
1870 Sun Sep 18 11:42:50 1994 Francois Pinard (pinard@icule)
1872 * src/Makefile.in (TAGS): Include a ../lib/TAGS reference.

1883 unreacheable and useless.
1885 * doc/Makefile.in (texclean): Deleted, merged in mostlyclean.
1887 * lib/Makefile.in (DISTFILES): Distribute TAGS.
1888 (distclean): Do not remove TAGS.
1889 (realclean): Remove it.
1890 * Makefile.in: Make TAGS in lib also, not just in src.
1891 Reported by Karl Berry.
1893 * Makefile.in (distclean, realclean): Instead of recursively
1894 calling $(MAKE) for the -local part, allow parallel execution of
1895 -recursive and -local, only delay the removal of config.status,
1896 which is repeated in both goals.
1897 \f
1898 Tue Sep 13 19:21:05 1994 Francois Pinard (pinard@icule)
1900 * Release 1.3.
1902 * Makefile.in: Group all *clean-recursive goals in one, using sed
1903 to remove `-recursive' while calling make recursively. Also, use
1904 a subshell for each recursive $(MAKE).
1905 Reported by Jim Meyering.
1907 * src/m4.h (memcpy): Define with bcopy for BSD systems.
1908 Reported by Kaveh R. Ghazi.
1910 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
1911 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
1912 specify it.
1914 * configure.in: Use date instead of touch for stamp-h.
1915 * Makefile.in (stamp-h.in): Idem.
1917 * Makefile.in (distclean, realclean): Force serial execution of
1918 both goals, in case parallel makes are being used.
1919 Reported by Jim Meyering.

1934 ./install.sh will not be correctly referred to in sub-Makefiles.
1935 Reported by John David Anglin.
1937 * doc/Makefile.in (texclean): Remove *.cps and *.fns too.
1938 Reported by Eric Backus.
1940 * Makefile.in, checks/Makefile.in, doc/Makefile.in,
1941 examples/Makefile.in, lib/Makefile.in, src/Makefile.in: Limit

1945 Reported by Jim Meyering.
1947 Tue Sep 6 12:07:33 1994 Francois Pinard (pinard@icule)
1949 * configure.in: Correct stack overflow detection logic, taking
1950 care of systems having only incomplete implementations (like for
1951 Pyramid 9820 OSx 5.0d).
1952 Reported by Kaveh R. Ghazi.
1954 * src/Makefile.in (TAGS): Remote -t from etags call.
1956 Fri Sep 2 10:37:10 1994 Francois Pinard (pinard@icule)
1958 * lib/Makefile.in (install): Depend on all.

1962 * examples/Makefile.in (mostlyclean): Do not depend on texclean.
1963 Reported by Jim Meyering and John David Anglin.
1965 * Makefile.in (distclean-local): Delete config.log.
1966 Reported by Jim Meyering.
1968 Solidify frozen files with respect to -P:
1969 * src/m4.c: Have -P set prefix_all_buitins variable instead of
1970 calling a function by that name. Declare the variable.
1971 * src/m4.h: Adjust declaration for prefix_all_buitins.
1972 * src/builtin.c (builtin_init): Merge in functionality from
1973 previous prefix_all_buitins function, while making entries in the
1974 symbol table, but not modifying the builtin description itself.
1976 * src/freeze.c (reload_frozen_state): Add a useless `break;',
1977 because *many* compilers do not accept an empty `default:'.
1978 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
1979 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
1981 * configure.in: Use AC_TYPE_SIGNAL.
1982 * src/stackovf.c (setup_stackovf_trap): Use RETSIGTYPE.
1983 Reported by Robert Bernstein.
1985 * checks/Makefile.in (check): Modify PATH so check-them will find
1986 m4 in the src directory.
1987 * Makefile.in (check): Don't.
1988 Reported by Akiko Matsushita and Jim Meyering.
1990 * src/output.c (make_room_for, output_character_helper): New
1991 functions, for implementing a global MAXIMUM_TOTAL_SIZE instead of
1992 a per buffer MAXIMUM_BUFFER_SIZE.
1994 * src/output.c (output_text): New function, for optimizing the
1995 output of strings of characters. Use it.
1997 Tue Aug 30 01:44:29 1994 Francois Pinard (pinard@icule)
1999 * doc, src: New directories reorganizing the distribution.
2000 * doc/Makefile.in, src/Makefile.in, examples/Makefile.in: New
2001 files.
2002 * Makefile.in: Adjusted.
2003 * configure.in: Configure new Makefiles.
2005 * m4.h: Declare STRING typedef. Use it for comment and quote
2006 strings, adjusting all references. (This is the rudiments of a
2007 beginning for the eventual withdrawal of NUL terminated strings.)
2008 * output.c (shipout_text): Accept a length parameter, and use it.
2009 All callers adjusted.
2011 Mon Aug 29 12:27:19 1994 Francois Pinard (pinard@icule)
2013 * m4.h: Include <unistd.h> if it exists.
2014 * stackovf.c: Don't.
2016 Clean up for current_diversion variable:
2017 * output.c: Move current_diversion from builtin.c.

2020 current_diversion.
2021 * builtin.c (builtin_init, m4_divert): Leave current_diversion
2022 alone.
2024 Remove limit on number of diversions:
2025 * output.c: Replace ndiversion by diversions, declare it.
2026 (output_init): Allocate only diversion 0.
2027 (make_diversion): Allocate new diversions as needed.
2028 * m4.h, m4.c: Remove NDIVERSIONS and ndiversion related stuff.
2029 * m4.c: Still accept -N, but do nothing with it.
2030 Reported by David MacKenzie.
2032 Freeze diversions:
2033 * output.c (freeze_diversions): New function.
2034 * m4.h: Declare freeze_diversions.
2035 * freeze.c: Document frozen file format, revise it, call
2036 freeze_diversions to add diversions to frozen format, and code to
2037 reload them properly.
2038 * m4.c: Do not undivert automatically at end when status being
2039 frozen. Do not call builtin_init when reloading frozen state.
2041 Speed up diversion processing:
2042 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
2043 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
2044 structure and variables, cached variables out of output_diversion,
2045 reallocate_diversion_for and OUTPUT_CHARACTER.
2046 (shipout_text, make_diversion, insert_diversion): Adapted to new
2047 structures.
2048 (insert_file): Use better buffering.
2049 Reported by David MacKenzie.
2051 Sun Aug 28 05:20:02 1994 Francois Pinard (pinard@icule)
2053 * Makefile.in, lib/Makefile.in, checks/Makefile.in: Arrange so
2054 dist works from another build directory.
2056 Sat Aug 27 14:32:45 1994 Francois Pinard (pinard@icule)
2058 * symtab.c (hack_all_symbols): Use hash_table_size instead of
2059 constant HASHMAX, for -H option to work better.
2061 * builtin.c (DECLARE): Simplify by using _ ().
2063 * freeze.c: New file.
2064 * Makefile.in: Compile it, distribute it.
2065 * m4.c: Recognize, document and process --freeze-state (-F) and
2066 --reload-state (-R) options. Pass a true flag to builtin_init
2067 only if no reloading some state.
2068 * builtin.c (define_builtin): Remove static specifier.
2069 (find_builtin_by_name): Remove static specifier.
2070 (builtin_init): Accept and obey a flag argument.

2073 Wed Aug 24 16:14:19 1994 Francois Pinard (pinard@icule)
2075 * builtin.c (dumpdef_cmp): Rewrite so the cast protect the const
2076 specifier.
2078 * configure.in: Implement --with-dmalloc.
2079 * acconfig.h: Document WITH_DMALLOC.
2080 * m4.h: Add code for when WITH_DMALLOC.
2082 Mon Aug 15 12:38:05 1994 Francois Pinard (pinard@icule)
2084 * m4.c (long_options): Use "error-output", the dash was missing.
2085 Reported by Akiko Matsushita.
2087 Fri Aug 12 16:38:01 1994 Francois Pinard (pinard@icule)
2089 * m4.h: Include <sys/types.h>.
2090 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
2091 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
2092 int.
2093 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
2094 as size_t, not int.
2095 * builtin.c (dump_args): Declare len as size_t, not int.
2097 * debug.c: Prototype the forward declaration of debug_set_file.
2099 * builtin.c (m4_undivert): Replace div by file, for avoiding the
2100 shadowing of this variable.
2101 * output.c (insert_diversion): Idem.
2103 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
2104 (input_init): Duplicate default quote and comment strings.

2108 Duplicate even default comment strings.
2110 * configure.in: Updated for Autoconf 2.0.
2111 * Makefile.in (distclean-local): Also delete config.cache.
2113 * m4.c (usage): Reorganize the --help output by topic. Include a
2114 description for debugging flags.
2116 Fri Jul 29 10:15:52 1994 Francois Pinard (pinard@icule)
2118 * configure.in: If sigaction is available and SA_ONSTACK defined,
2119 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
2120 defined, use sigvec. Else don't compile stackovf.c.
2121 * stackovf.c (setup_stackovf_trap): Idem.
2122 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
2123 and Simon Leinen.
2125 Thu Jul 21 22:43:17 1994 Francois Pinard (pinard@icule)
2127 * m4.c (usage): Replace printf par fputs.
2128 \f
2129 Mon Jul 18 23:48:23 1994 Francois Pinard (pinard@icule)
2131 * Release 1.2
2133 Sun Jul 17 08:08:25 1994 Francois Pinard (pinard@icule)
2135 * configure.in: Check for sigaction and sigvec. Add a new delayed
2136 check for RLIMIT_STACK, combine in the checking for getrlimit.
2137 All those things are not universally available.
2138 * stackovf.c: Split setting up the trap handler and catching
2139 signals, for better taking care of various configure outcomes.
2140 * examples/stackovf.sh: Correct a typo.
2141 Reported by Eric Backus, Jim Avera and Jim Meyering.
2143 Sat Jul 16 20:36:19 1994 Francois Pinard (pinard@icule)
2145 * ansi2knr.c: New version sent by its author, Peter Deutsch.
2147 Fri Jul 15 14:36:21 1994 Francois Pinard (pinard@icule)
2149 * Makefile.in: Modify so parallel make will not try making
2150 lib/libm4.a twice simultaneously.
2151 Reported by Jim Meyering.
2153 Thu Jul 14 17:23:17 1994 Francois Pinard (pinard@icule)
2155 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
2156 error message, for when no code possibility exists. Even if this
2157 line is completely #ifdef'ed out, it brings a syntax error.
2158 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
2160 * Makefile.in (install): Have install depend on all too, for lib
2161 to be remade as needed.
2163 * examples/stackovf.sh: Try ksh, bsh and bash for shells
2164 providing ulimit, instead of using only ksh.
2165 Reported by Jim Avera and Joseph E. Sacco.
2167 Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
2169 * Makefile.in (check): Have it depend on all instead of m4. In
2170 this way, a change in lib will be detected and processed.
2172 * builtin.c (numeric_arg): Use strtol and verify the conversion,
2173 instead of using sscanf which stops as soon as there is a
2174 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
2175 and divert(1xyzzy) were all accepted without any warning or error
2176 messages.
2177 * m4.h: Declare strtol as long if not including stdlib.h.
2178 * configure.in: Check for limits.h, and replace strtol if missing.
2179 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
2180 * lib/strtol.c: New file, from elsewhere.
2181 Reported by Andreas Schwab.
2183 Thu Jul 7 22:38:10 1994 Francois Pinard (pinard@icule)
2185 * macro.c (expand_macro): Cast value to (boolean) prior to
2186 assigning it to traced.
2187 Reported by Tom McConnell.
2189 * Makefile.in (m4): Always make all in lib first.
2190 Reported by Jim Meyering.
2192 Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com)
2194 * stackovf.c: Isolated OS-dependent sections; Improved portability,
2195 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
2196 handlers), and a default error message if the fault address is not
2197 available (when neither siginfo.h nor BSD sigcontext are supported).
2198 * configure.in: Changes for stackovf.h: Check for sigcontext,
2199 sigaction, sigstack, and define rlim_t as int if necessary.
2200 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
2201 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
2202 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
2204 Tue Jul 5 19:13:54 1994 Francois Pinard (pinard@icule)
2206 * configure.in: Use AC_SET_MAKE.
2207 * Makefile.in: Use @SET_MAKE@.
2208 Reported by Jim Meyering.
2210 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
2211 Reported by Ian Taylor.
2213 Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
2215 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
2216 because siginfo.h is unrelated to standard headers, and siginfo.h
2217 is already checked for.
2218 Reported by Joseph E. Sacco.
2220 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
2221 PROTOTYPES.
2222 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
2223 AC_PROTOTYPES.
2225 Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
2227 * builtin.c (substitute): Use \& to represent this part of the
2228 string which was matched by the whole regexp, instead of
2229 representing the whole string. Any usage of \0 issues a warning
2230 and acts like \&, it will disappear in some subsequent release.
2232 Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
2234 * m4.c: Complete prototype for forwarded declaration of usage.
2236 * input.c (init_macro_token): Correct own reference in error
2237 message. Previous name get_macro_func was referred to instead.
2238 (next_char): Correct own reference in error message. Previous
2239 name advance_input was referred to instead.
2241 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
2242 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
2243 and_term, not_term, logical_not_term, cmp_term, shift_term,
2244 add_term, mult_term, exp_term, unary_term, simple_term): Add
2245 prototype to forwarded declarations. Declare parameter v1 as
2246 eval_t * instead of int *. Same for local variable v2 in dyadic
2247 functions. Same for result in exp_term.
2248 * builtin.c (m4_eval): Declare value as eval_t instead of int.
2249 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
2250 unsigned_eval_t instead of unsigned int. Change casts accordingly.
2251 (shipout_int): Cast first argument of ntoa to eval_t.
2252 Reported by Thorsten Ohl.
2254 * macro.c: Complete the prototypes of forwarded expand_macro and
2255 expand_token.
2256 Reported by Thorsten Ohl.
2258 * m4.h: Define voidstar as void * or char * depending on __STDC__.
2259 The Ultrix 3.1 compiler cannot do much with void pointers.
2261 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
2262 * m4.c (xfree): Replace void * by voidstar.
2263 Reported by Tom McConnell.
2265 * ansi2knr.1: New, from elsewhere.
2266 * Makefile.in (DISTFILES): Distribute ansi2knr.1
2268 * Makefile.in (stamp-h.in): Avoid running ./config.status if
2269 stamp-h does not exist yet. This avoids running it a second time
2270 just after the initial ./configure.
2271 Reported by David MacKenzie and Tom McConnell.
2273 * m4.h: Replace the enum debug_info declaration with a series of
2274 #define's. The Ultrix 3.1 compiler would otherwise need casting
2275 (int) to most references, when used in expressions.
2276 Reported by Tom McConnell.
2278 Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
2280 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
2281 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
2282 calls the compiler. Previously, FP_PROTOTYPES was only calling
2283 the preprocessor; by not being subject to CFLAGS, this was
2284 discouraging those flags asking for ANSI compilation.
2285 * acconfig.h: Document HAVE_PROTOTYPES.
2286 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
2287 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
2288 Reported by Eric Backus.
2290 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
2291 from the environment. Default CFLAGS to -g if not set.
2292 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
2293 * lib/Makefile.in: Have CFLAGS substituted from configure.
2294 Reported by Eric Backus and Tom McConnell.
2296 * configure.in: m4_undefine changeword before using AC_ENABLE.
2298 * m4.h: Declare prototypes for error (for ANSI compilers only),
2299 prefix_all_builtins and reference_error.
2300 Reported by Tom McConnell.
2302 * input.c (set_word_regexp): Do not try to initialize the array
2303 test from a string, this does not work with non-ANSI compilers.
2304 Reported by Eric Backus.
2306 * Makefile.in (dist): Clean examples/ before saving it.
2307 (distclean-local): Also remove stamp-h.
2308 Reported by Eric Backus.
2310 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
2311 non ANSI compilers.
2312 Reported by Tom McConnell.
2314 * checks/Makefile.in (clean): Depends on mostlyclean.
2315 (mostlyclean): New goal.
2317 Fri Jun 24 23:30:31 1994 Francois Pinard (pinard@icule)
2319 * Makefile.in (DISTFILES): Distribute install.sh.
2320 * install.sh: New file, copied from elsewhere.
2321 Reported by Assar Westerlund and Kaveh R. Ghazi.
2323 Thu Jun 23 00:00:30 1994 Francois Pinard (pinard@icule)
2325 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
2326 * acconfig.h: Explain ENABLE_CHANGEWORD.
2328 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
2329 from code provided by Pete Chown]
2330 * m4.h: Add original_text field to u_t variant of union u.
2331 Declare TOKEN_DATA_FUNC macro.
2332 * builtin.c: Declare changeword.
2333 (m4_changeword): New function.
2334 * input.c: Include "regex.h", define variables with word regexps.
2335 (input_init): Initialize the word regexp.
2336 (set_word_regexp): New.
2337 (next_token): Declare local variables, use the previous code if
2338 default_word_regexp is true. Else, match using a new code. Save
2339 the original text.
2340 * macro.c (expand_token): Ship out original text if not a macro
2341 name.
2342 Reported by Krste Asanovic and Pete Chown.
2344 [These modifs all depend upon ENABLE_CHANGEWORD]
2345 * m4.h: Declare external user_word_regexp.
2346 * m4.c: Declare user_word_regexp, and initialize it from
2347 --word-regexp or -W, or NULL if not specified.
2348 * input.c: Use user_word_regexp if specified, instead of
2349 DEFAULT_WORD_REGEXP.
2351 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
2352 agree with it.
2354 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
2355 * checks/Makefile.in: Empty the suffix list.
2356 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
2358 * m4.c: Declare nesting_limit and initialize it to 250.
2359 Implement -LNUMBER or --nesting-limit=NUMBER to change its
2360 value.
2361 * m4.h: Declare nesting_limit as external.
2362 * macro.c (expand_macro): Stop execution whenever nesting limit
2363 is exceeded.
2364 Reported by Bengt Mertensson.
2366 * eval.c (evaluate): Diagnose excess characters in eval input.
2367 Things like `eval(08)' used to return 0 with no diagnostic.
2369 * m4.h: Capitalize first letter of all macro arguments in
2370 definitions.
2372 * m4.c: Declare warning_status, initialize it to 0. Add new
2373 option -E, or --fatal-warnings, which sets warning_status to
2374 EXIT_FAILURE instead.
2375 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
2376 EXIT_FAILURE if not otherwise done by header files.
2377 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
2378 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
2379 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
2380 argument of all M4ERROR calls.
2381 Reported by Noah Friedman.
2383 * examples/incl-test.m4: Renamed from incl_test.m4.
2384 * examples/include.m4: Include incl-test.m4 instead of
2385 incl_test.m4.
2386 * examples/multiquotes.m4: Renamed from multi-quotes.m.
2388 Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule)
2390 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
2391 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
2392 also tested it on a Sun Sparc workstation running SunOS 4.x.
2394 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
2395 49.format check, abusing a `union values' argument with sprintf
2396 without selecting the proper field. Now, save the formatting type
2397 first, delaying the fetch of the corresponding argument.
2398 Reported by Joseph E. Sacco and Tom Quinn.
2400 * format.c (format): Remove const from char *fmt declaration when
2401 not HAVE_EFGCVT, because a NUL may be forced into it.
2403 * m4.h: Declare atof() when not STDC_HEADERS.
2404 Reported by Joseph E. Sacco.
2406 * Regenerate configure using Autoconf 1.11, this corrects a
2407 problem about an incorrect cpp seting on NeXT 3.1.
2408 Reported by Alexander Lehmann.
2410 Sun Jun 5 16:25:19 1994 Francois Pinard (pinard@icule)
2412 * m4.h (_): Change argument from `x' to `Args'.
2414 Wed May 4 23:59:39 1994 Francois Pinard (pinard@icule)
2416 * Makefile.in: Remove all occurrences of $(MFLAGS), which were
2417 bringing more evil than good on a few systems.
2418 Reported by Greg A. Woods.
2420 Fri Apr 22 15:59:35 1994 Francois Pinard (pinard@icule)
2422 * m4.h: Rename Args() to _().
2423 * m4.h: Remove extern specifier from all function declarations.
2425 Fri Apr 22 15:51:21 1994 Jim Avera (jima@netcom.com)
2427 * stackovf.c: New file implementing stack-overflow detection.
2428 * configure.in: Check for getrlimit, sigaction. If all of
2429 standard headers, getrlimit and sigaction, define USE_STACKOVF and
2430 substitute ${U}stackovf.o for STACKOVF.
2431 * acconfig.h: Declare USE_STACKOVF.
2432 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
2433 * m4.h: Declare setup_stackovf_trap().
2434 * m4.c: Call setup_stackovf_trap().
2435 * tests/stackovf_test.sh: New file.
2437 Wed Apr 13 14:10:30 1994 Francois Pinard (pinard@icule)
2439 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
2441 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
2443 Sun Jan 30 14:24:19 1994 (pinard at icule)
2445 * m4.h: Remove definition of volatile, not used anymore.
2446 Reported by Jim Meyering and Joseph E. Sacco.
2448 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
2449 of `if ... else /* nothing */' for if macros.
2450 Reported by Jim Meyering.
2452 * builtin.c (m4_regexp): Reorganize the code for avoiding a
2453 warning from gcc about `repl' possibly used before defined.
2454 Reported by Jim Meyering.
2456 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
2457 Reported by Jim Meyering.
2459 Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)
2461 * m4.h: Move the conditional definition of volatile after the
2462 inclusion of system files, because they may define it first.
2464 Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
2466 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
2467 get around a problem with Alpha make seeing a syntax error, there.
2468 Reported by Vern Paxson.
2470 Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)
2472 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
2473 Reported by Richard Stallman.
2475 Sat Dec 25 08:06:05 1993 Francois Pinard (pinard@icule)
2477 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
2478 instead of AC_HAVE_FUNCS.
2479 Reported by Noah Friedman.
2481 Wed Dec 1 09:37:53 1993 Francois Pinard (pinard@icule)
2483 * m4.c: Initialize show_help and show_version to zero.
2485 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
2486 Use them in exit() and usage() calls.
2488 Sat Nov 27 10:43:24 1993 Francois Pinard (pinard@icule)
2490 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
2491 syserr() macro. Delete errref, add reference_error and M4ERROR.
2492 * m4.c: Replace errref, which was returning an input reference
2493 string, with reference_error, which prints it on standard error.
2494 * builtin.c, output.c: Use errno as second parameter to error,
2495 instead of using syserr() with %s.
2496 * *.c: Use M4ERROR instead of error: no more errref() with %s.
2497 Doing so, the program name appears after the input reference
2498 instead of before, which eases M-x next-error processing.
2500 Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
2502 * checks/get-them: Escape braces with backslashes in patterns,
2503 because HPUX-9.01 awk needs this.
2504 Reported by Jim Meyering.
2506 Mon Nov 22 10:55:52 1993 Francois Pinard (pinard@icule)
2508 * builtin.c: Declare "FILE *popen ();".
2510 * m4.h: Remove MESSAGE{,1,2}, WARNING1, FATAL{,1}, INTERNAL_ERROR
2511 macros, replace error_message_prefix() declaration by errref()'s.
2512 Declare xrealloc, for use in errref().
2513 * m4.c: Delete error_message_prefix() function, add errref().
2514 * *.c: Use error() systematically in place of all error macros,
2515 now that error() flushes stdout first. Make needed adjustments.
2517 * m4.h: Remove const in sys_errlist[] declaration, it creates
2518 conflicts on SGI and Alpha.
2519 Reported by Kaveh R. Ghazi.
2521 Sat Nov 20 08:26:15 1993 Francois Pinard (pinard@icule)

2537 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
2539 * input.c (input_init): Initialize quote and comment strings
2540 explicitely instead of calling set_quotes and set_comment: by
2541 doing so, we ensure we do not free uninitialized variables.
2543 * checks/check-them: Reverse arguments to both diff, so the
2544 expected is on the left and the obtained on the right.
2546 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR

2550 routines, add error_message_prefix routine.
2551 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
2552 warning with WARNING*, fatal with FATAL* and internal_error with
2553 INTERNAL_ERROR*.

2570 (trace_format): Use stdarg instead of varargs if __STDC__.
2572 * configure.in: Remove checks for vfprintf and _doprnt. These

2595 * Makefile.in (m4.dvi): Use m4.texinfo instead of m4.texi.
2596 Reported by Joel Sherrill.
2598 * builtin.c (prefix_all_builtins): Instead of the table size, use
2599 the null entry at end for stopping the loop. It was overwritten.
2600 Reported by Andreas Schwab and Jim Meyering.
2602 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
2603 Reported by Kaveh R. Ghazi.

2629 * Release 1.1
2631 * configure.in: Do not copy check files in the build hierarchy.

2793 ensure 777 mode for directories, so older tar's will restore file
2794 modes properly.
2796 Sun Jan 17 15:38:05 1993 Francois Pinard (pinard@icule)
2798 * Makefile.in, lib/Makefile.in: Put $(CFLAGS) after $(CPPFLAGS),

2830 macro.c, output.c, path.c, symtab.c: Change Copyright from
2831 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.

2841 Sun Dec 20 10:40:20 1992 Francois Pinard (pinard at icule)
2843 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user
2844 might well use CFLAGS is s/he needs it.
2846 * Makefile.in: Allow installation of info files from a separate
2847 build directory.
2848 Reported by Jason Merrill.
2849 Reported by David MacKenzie.
2850 Reported by Skip Montanaro.

2857 This is still a beta release for the future GNU m4 version 1.1.
2859 * lib/alloca.c: New, from elsewhere.
2860 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
2862 * m4.h: Do not define index/rindex if already defined. If
2863 FALSE/TRUE are already defined, do not redefine them, but merely
2864 define boolean typedef to int.
2866 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
2867 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
2868 because some C compilers do not like connectives with #ifdef.
2869 * m4.h: Define `volatile' only if __GNUC__, instead of once for
2870 __GNUC__ and once for __STDC__.
2871 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
2873 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
2874 Makefile dependencies. Without it, make keeps destroying and
2875 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
2877 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
2878 to diversion/DIVERSION, this was a spelling error.
2880 * m4.c: Declare version[], remove #include "version.h".
2881 * version.h: Deleted.
2882 * Makefile.in: Remove references to version.h.
2884 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
2885 production, by using a simpler and more robust algorithm. This
2886 solves the problem of synclines sometimes written in the middle of
2887 an output line. Delete sync_line() and output_lines variable.
2888 * m4.h: Remove sync_line prototype and output_lines declaration.
2889 * input.c (next_char), output.c (shipout_text): Remove references
2890 to output_lines.
2891 * input.c (push_file, pop_file): Merely put the value -1 in
2892 output_current_line instead of calling sync_line, for delaying a
2893 single `#line NUM FILE' before next output line. Do not test
2894 for sync_output, because this is unnecessary clutter.
2895 * output.c (make_divertion, insert_divertion): Idem.
2896 * input.c: Rename must_advance_line to start_of_input_line, for
2897 consistency.
2899 * debug.c (trace_header): Select a new debug line format, which
2900 better complies with GNU standards for formatting error messages.
2901 With option `-dfl', M-x next-error might be used on the output.
2902 * m4.c (vmesg): Adjust format of error output to GNU standards.
2903 * m4.texinfo: Adjust examples for `make check' to work.
2905 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
2906 case for enum debug_info constants, which were all lower case.
2908 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
2909 re_search_2.
2910 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
2911 collected patches. I tried a few times using newer regex.[ch], it
2912 mysteriously stopped aborting with this one. Insecure feeling...
2913 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
2915 Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
2917 * m4.c: Change `--no-warnings' to `--silent'.
2918 Reported by David MacKenzie.
2920 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
2921 leave it off for now. See comment in m4.c for justification.
2922 Reported by David MacKenzie.
2924 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
2925 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
2927 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
2929 * Makefile.in: Ensure recursive cleaning is done before local
2930 cleaning for all clean goals.
2932 * builtin.c (ntoa): Ensure the value is always interpreted as a
2933 signed quantity, whatever the radix is.
2935 Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
2937 * builtin.c, format.c, input.c: Split long lines.
2938 * m4.c: Use typedef macro_definition instead of struct
2939 macro_definition.
2940 * symtab.c: Use typedef symbol instead of struct symbol.
2942 Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
2944 * *.[ch]: Remove all trailing whitespace, in code and comments.
2946 * configure.in: Find some awk.
2947 * Makefile.in: Add $(AWK) to MDEFINES.
2948 * checks/Makefile.in: Transmit $(AWK) to get_them.
2949 * checks/get_them: Use $AWK instead of gawk. Add a close in the
2950 awk script when switching files, because without this, mawk runs
2951 out of file descriptors.
2953 Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
2955 * Makefile.in (realclean): Delete m4.info*.
2956 Reported by Jim Meyering.
2958 * Makefile.in: Adjust and link with checks/Makefile.
2959 * checks/Makefile.in: New.
2960 * configure.in: Output checks/Makefile.
2962 * checks/get_them: Have the dnl header of each test more
2963 recognizable by next-error, also use a better message.
2965 Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
2967 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
2968 And use that only if __GNUC__ since we're using it's GCC-specific
2969 semantics that tell the compiler the associated function doesn't
2970 return.
2972 * builtin.c (substitute): Don't use character as an array index.
2973 (dumpdef_cmp): Make formal arguments `const void *' to avoid
2974 warnings with gcc -W -Wall on systems with qsort prototype.
2975 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
2976 from gcc -W -Wall.
2978 * eval.c (most functions): Add parentheses to assignments used
2979 as truth values go avoid warnings from gcc -Wall.
2981 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
2982 any functions that don't need external scope.
2984 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
2985 (many functions and arrays): Declare `const'.
2987 Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
2989 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
2990 removing the declaration from m4.h. Also rename false to FALSE
2991 and true to TRUE.
2993 * lib/Makefile.in (Makefile): New goal.
2995 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
2996 so heavily loaded. It gets more easily overridable, calling make.
2997 Reported by Jim Meyering.
2999 * Makefile.in (dist): Get .fname from the current directory name,
3000 instead of from version.h. I need updating many files manually,
3001 when the version changes, version.h is just one of them.
3003 Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
3005 * m4.h: Remove the tag `boolean' on the enum introducing typedef
3006 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
3007 Reported by Tom McConnell.
3009 Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
3011 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
3012 39.cleardiv, which were describing missing or spurious newlines.
3013 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
3014 do not depend on machine word size, `/bin/false' implementation,
3015 or `wc' output format. `make check' is more dependable, now.
3017 * checks/check_them: Summarize the failed tests by listing their
3018 name, at end. If none, issue `All checks successful'. Output
3019 `Checking' instead of `Input file:'.

3029 * input.c (next_token): Reinitialize token_buttom just after using
3030 it as a watermark with obstack_free. Or else, a future token, big
3031 enough for triggering reallocation of the obstack chunk, could
3032 void the initialized value of token_buttom, later causing panic in
3033 obstack_free. Rename token_buttom to token_bottom everywhere.
3035 * m4.h: Before declaring errno, first include <errno.h> and
3036 ensure that it does not define errno.
