523 define HAVE_INT8_T, and likewise for similar macros.
524 Problem reported by Patrick Welche in
525 <http://lists.gnu.org/archive/html/autoconf/2007-05/msg00062.html>.
527 2007-05-25 Noah Misch <noah@cs.caltech.edu>
529 * bin/Makefile.am ($(top_builddir)/bin/autom4te): New dependency.
531 2007-05-21 Paul Eggert <eggert@cs.ucla.edu>
533 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp
534 choice, since that's what we do with --enable-largefile etc.
535 Redo indenting and assignments to simplify things a bit, and make
536 the parens work with Emacs.
538 * doc/autoconf.texi (Generic Compiler Characteristics): Fix typo

615 section titles and other comments; no code change.
617 2007-05-01 Kevin Ryde <user42@zip.com.au>
619 * doc/autoconf.texi (Particular Programs): Typo
620 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
622 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
624 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that

634 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
636 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
637 for a.* when searching for executables, as this prevents users
638 from having files like a.c. Problem reported by Ralf Wildenhues in:
639 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html

650 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
651 AC_CHECK_TYPE, AC_CHECK_TYPES.
652 * doc/autoconf.texi (Generic types): C types must be type-names
653 (the C terminology), not type-ids (the C++ term). C++ types
654 must not be anonymous.
655 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
656 for C++; this drops support for anonymous struct and union types,
657 which were problematic anyway.
658 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
659 for C++.
661 2007-04-12 Jim Meyering <jim@meyering.net>

673 * doc/autoconf.texi (Generic Types): Document the restrictions
674 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
675 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
676 with objects too. Document the restrictions on its use.
677 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
678 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
679 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
680 works but the latter doesn't, then it's a valid type.
681 This lets people use function types and so forth.
682 For C++ there doesn't seem to be a simple solution, so leave it alone.
683 (AC_CHECK_SIZEOF): Allow argument to be a variable.
684 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
685 AC_CHECK_TYPE; that wasn't documented or necessary.
687 2007-04-11 Stepan Kasal <kasal@ucw.cz>
689 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
690 when cross-compiling.

710 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
711 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by

737 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
738 nonstandard grep R.E. escape sequences.
740 2007-03-17 Jim Meyering <jim@meyering.net>
742 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
743 (Limitations of Usual Tools): Also list \< and \>, and mention that
744 HP-UX's grep, like the one from Solaris, does not support that syntax.
746 2007-03-09 Stepan Kasal <kasal@ucw.cz>
748 * doc/autoconf.texi (Specifying Names): `--host' does not
749 change the build type.
751 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
753 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
754 suggests AC_CONFIG_HEADERS.

765 universal binaries. Problem reported by Elias Pipping.
767 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
769 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
770 * doc/autoconf.texi (C Compiler): Document this. There is a new
771 extra argument ACTION-IF-UNIVERSAL.
772 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
773 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
774 Reindent for sanity's sake.
776 2007-02-24 Eric Blake <ebb9@byu.net>

787 status of rm so we know when it failed.
788 If cleaning of test dir failed before running the test, warn.

801 errors introduced in last change.
803 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
805 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to

807 carriage return.
808 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
809 with traditional Awk and begin.
810 * tests/torture.at (Limitations of Builtins): Document the problem

842 * THANKS (people): Update.
844 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
846 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the

853 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
855 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
856 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
857 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
858 substitution will still be done by the special code.
859 Report by Jim Meyering.
861 * doc/autoconf.texi (File System Conventions): Mention that
862 $PATH_SEPARATOR is for the build system only.

880 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
882 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
883 early on the reader side, drop stderr of the input to avoid
884 `broken pipe' error output; this may happen even with shell
885 builtin `echo' of some bash versions. Reports by Ian Macdonald
886 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
888 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
890 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

900 Fix some wording problems noted by Paolo Bonzini in:
901 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
902 * doc/autoconf.texi (Signed Overflow Examples): Give more
903 discussion about the allow_superuser_privileges example,
904 and change it a bit to make things clearer.
905 (Optimization and Wraparound): Clarify whether the compiler
906 will generate an infinite loop for the example derived from
907 Autoconf's mktime test.
908 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
909 Also, clarify unsigned multiplication overflow.
911 2007-01-04 Eric Blake <ebb9@byu.net>
913 * bin/Makefile.am (RELEASE_YEAR): New macro.
914 (edit): Use it to supply correct copyright year to scripts.
915 * bin/autoconf.as (version): Use it.
916 * bin/autoheader.in ($version): Likewise.
917 * bin/autom4te.in ($version): Likewise.

919 * bin/autoscan.in ($version): Likewise.

923 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
925 * doc/autoconf.texi (Integer Overflow): Revised based on today's
926 feedback. The most important changes document what happens when
927 you convert an out-of-range value to a signed integer type, and
928 say that (sum < a) != (b < 0) reliably detects overflow when sum =
929 a + b.
931 * doc/autoconf.texi (Integer Overflow): Greatly expand and
932 rewrite, taking notions from the recent discussion on the gcc and
933 autoconf mailing lists; please see
934 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
935 and follow the many links.
936 (Integer Overflow Basics, Signed Overflow Examples):
937 (Optimization and Wraparound, Signed Overflow Advice):
938 (Signed Integer Division): New sections.
940 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
942 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
943 preprocessor macro arguments in traced name.
944 * doc/autoconf.texi (Defining symbols): Document longstanding
945 support for AC_DEFINE-ing macros with arguments, and document
946 behavior when the same variable has multiple AC_DEFINEs.
947 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
948 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
949 macros directly, giving much shorter and simpler code.
951 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
953 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
954 space before "$ac_configure_args" to prevent a 'config.status
955 --recheck' failure if ac_configure_args doesn't contain a leading
956 space. This works around a problem with the XEmacs configure.ac,
957 which uses the (undocumented) ac_configure_args variable
958 inconsistently with Autoconf.
960 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
962 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
963 Include <limits.h>, and use its INT_MAX to rewrite the
964 j loop so that it does not overflow 'int'. Problem reported by
965 Ralf Wildenhues in
966 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
967 Play it safe by shifting left by 1 rather than multiplying by 2,
968 as GCC is less likely to optimize this away when the value
969 is signed (when it assumes overflow leads to undefined behavior).
970 Also, don't assume time_t uses two's complement.
972 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
974 * tests/torture.at (Substitute a 2000-byte string): Avoid using
975 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
976 dumps core on it. Report by Tim Rice.
978 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
980 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
981 --disable-option-checking to --help output even when
982 AC_PRESERVE_HELP_ORDER is not used.
983 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
984 --with argument, rather than argument with [-.] replaced by
985 underscores.
986 * NEWS: Fix typo in previous change; the news was in the
987 wrong section.
989 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
991 * NEWS: Warnings are now generated by default for unknown
992 --enable-* and --with-* options.
993 * doc/autoconf.texi (Option Checking): Renamed from
994 (Configure Option Checking). Tighten up the wording a bit.
995 (External Software, Package Options): Cross-reference to Option
996 Checking, and use this to shorten our section.
997 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
998 "$x" to test "x$foo" != x.
999 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
1000 Don't warn if $enable_option_checking is "no".
1001 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
1002 ac_unrecognized_opts to the empty string.
1003 Don't echo the unrecognized opts, as this might mishandle
1004 backslashes or leading -.
1005 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
1006 usage next to the other --disable-FEATURE options in the
1007 help string.
1009 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1011 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
1012 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
1013 Print warning for unrecognized --with and --enable options
1014 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
1015 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
1016 Disable option checking when subdirs are configured.
1017 (AC_OUTPUT): If warnings are enabled, print warning about
1018 unrecognized --with and --enable options at the end of
1019 the configure output (as well as at the beginning).
1020 * doc/autoconf.texi (Option Checking): New node.
1021 Document new option warning functionality.
1023 2006-12-16 Eric Blake <ebb9@byu.net>
1025 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
1026 * NEWS: Start news for current version.
1028 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
1030 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1031 Define HAVE_GETMNTENT to 1, not to the empty string.
1032 Problem originally reported by Jochen Friedrich in
1033 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
1035 This change prompted by a problem report by Andrey Simonenko in
1036 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
1037 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
1038 object-like macros only, in the traditional portable character
1039 set.
1040 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
1041 Warn about attempts to define things that are not identifiers.
1042 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
1043 awful hack that AC_DEFINEd macro names containing parentheses.
1045 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
1047 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
1048 too drastic, even if Texinfo in theory requires it for info mode.
1050 (config.status Invocation): Renamed back from Recreating a
1051 Configuration).
1052 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
1053 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
1055 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1057 * NEWS: Version 2.61a.
1059 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1060 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1062 * NEWS: Document changes with echo and printf, and the lack
1063 of limits on the total size of multi-line values of substituted
1064 variables, and the AC_FUNC_FSEEKO fix.
1066 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
1068 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
1069 Writing configure.ac.
1070 (Autoconf Input Layout): Renamed from configure.ac Layout.
1071 (Recreating a Configuration): Renamed from config.status Invocation.
1072 (Obsolete Recreation): Renamed from Obsolete config.status Use.
1073 (acconfig Header): Renamed from acconfig.h.
1074 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
1075 (Writing Testsuites): Renamed from Writing testsuite.at.
1076 (Autom4te Cache): Renamed from autom4te.cache.
1078 * BUGS: Remove mention of VPATH problem, since it's now documented
1079 not to be a bug in the Autoconf build procedure itself, but rather
1080 a problem with the proprietary `make' programs.
1082 * doc/autoconf.texi (Build Directories): Add a cross reference
1083 to VPATH and Make.
1085 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
1086 * doc/standards.texi: Sync from gnulib.
1088 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
1089 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
1090 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
1091 generated automatically.
1093 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
1095 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
1096 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
1097 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
1099 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1101 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
1102 `CEOF$ac_eof' special marker, the awk script cannot contain a
1103 line matching `^CEOF', so this is not needed any more.
1104 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
1105 special marker in the test.
1107 2006-12-06 Stepan Kasal <kasal@ucw.cz>
1109 * tests/tools.at (autom4te preselections): Use `find -newer';
1110 remove one of the sleeps.
1112 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
1113 more readable, using ...
1114 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
1116 * doc/autoconf.texi (autoheader Invocation): Do not double-
1117 quote the parameter of `AH_BOTTOM' in the example.
1119 2006-12-05 Stepan Kasal <kasal@ucw.cz>
1121 * doc/autoconf.texi (Configuration Headers): Remove the
1122 example with multiple input files.
1123 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
1124 multiple input files.
1126 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1128 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
1129 creating the awk substitution script, handle one input line at a
1130 time, so that the maximum length of a substituted (multi-line)
1131 value is not limited by the size of the sed pattern space.
1132 The trade-off is a slightly repetitive sed script.
1133 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
1134 can only have up to 7 characters, due to Solaris 10 /bin/sed.
1135 * tests/torture.at (Substitute a 2000-byte string): Increase the
1136 test with several long lines, they should not be caught by sed
1137 limits any more.
1139 * tests/tools.at (autom4te preselections): New test, to flag
1140 entries missing from autom4te.cfg.
1141 Report by David Byron <dbyron@hheld.com>.
1143 * tests/torture.at (Substitute a 2000-byte string): Actually use
1144 AC_PROG_AWK, so the last change works as intended.
1145 (Substitute and define special characters): Likewise.
1146 (Substitute a newline): Likewise.
1148 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
1149 instead of `awk' consistently.
1150 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
1151 * tests/torture.at (Torturing config.status): Test both the
1152 result of AC_PROG_AWK and plain awk.
1153 (Substitute a 2000-byte string): Likewise.
1154 (Substitute and define special characters): Likewise.
1155 (Substitute a newline): Likewise.
1157 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
1159 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
1160 can be assigned to a function pointer. Problem reported by
1161 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
1162 part of a patch by Ralf Wildenhues in that same bug report.
1164 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
1166 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
1167 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
1169 2006-12-01 Eric Blake <ebb9@byu.net>
1171 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
1172 cross-compiling from cygwin to mingw.
1173 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
1174 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
1175 to lib/autoconf/c.m4.
1177 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1179 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
1180 string for more reliable failure. Wrap the entire test that
1181 causes the broken Solaris printf to dump core, in a subshell,
1182 so the segmentation fault message is reliably suppressed.
1183 Fix shell expansion errors by using /usr/ucb/echo always;
1184 avoid an error on systems without it by another subshell.
1185 Avoid m4 expansion of `$1'. Set the zeroth argument of the
1186 subshell-$as_echo to `as_echo', for better error message.
1188 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1190 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
1191 `BASH_SOURCE' contain a newline, set them to empty, as they may
1192 not be unset.
1194 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
1196 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
1197 years and is too hard to maintain now. The last straw was
1198 reported by Jerker Baeck in
1199 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
1200 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
1201 * doc/autoconf.texi (Particular Functions): Move
1202 AC_FUNC_SETVBUF_REVERSED from here...
1203 (Obsolete Macros): ... to here. Say that it does nothing now.
1204 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
1205 Turn into (almost) a no-op.
1207 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
1208 (AC_C_VOLATILE):
1209 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
1210 These macros are obsolescent and new applications shouldn't need them.
1211 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
1212 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
1213 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
1214 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
1215 (AC_FUNC_VPRINTF): Likewise.
1216 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
1217 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
1218 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
1220 * doc/autoconf.texi (Setting Output Variables): Mention that
1221 @VAR1@VAR2 has unspecified behavior. Problem reported by
1222 Ralf Wildenhues.
1223 * NEWS: Mention this.
1225 * Makefile.am: Put only a single '#' into the copyright notice,
1226 so that it's also present in the output file. Standardize wording
1227 in makefile copyright notices to match GNU coding standards.
1228 * bin/Makefile.am: Likewise.
1229 * doc/Makefile.am: Likewise.
1230 * lib/Makefile.am: Likewise.
1231 * lib/freeze.mk: Likewise.
1232 * lib/autoconf/Makefile.am: Likewise.
1233 * lib/autoscan/Makefile.am: Likewise.
1234 * lib/autotest/Makefile.am: Likewise.
1235 * lib/m4sugar/Makefile.am: Likewise.
1236 * man/Makefile.am: Likewise.
1237 * tests/Makefile.am: Likewise.
1238 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
1239 one-line file.
1241 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1243 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
1244 in the sed script that mangles the awk script: delete up to the
1245 first exclamation mark only.
1246 * tests/torture.at (Substitute and define special characters):
1247 Test '!' too.
1249 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1251 Rewrite config files generation: avoid quadratic growth in
1252 the number of substituted variables by using awk instead of sed
1253 for the bulk of the substitutions.
1254 * NEWS: Mention this.
1255 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
1256 forbidden in the output (and thus input) file.
1257 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
1258 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
1259 generate just one large awk script for substitutions,
1260 eliminating much of the earlier complexity, while adding some
1261 new complexity. Only expand the substitution templates at
1262 configure time, for smaller configure script size. If
1263 _AC_SUBST_FILES are used, test 'awk' for working getline support
1264 at config.status time. If absent, interpolate through the
1265 shell. The awk script was written with much help
1266 from Paolo Bonzini and Paul Eggert.
1267 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
1268 (_AC_SED_FRAG_NUM): Likewise.
1269 (_AC_SUBST_CMDS): Renamed from...
1270 (_AC_SED_CMDS): ...this.
1271 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
1272 * tests/torture.at (Substitute a 2000-byte string): Also
1273 substitute a line with 1000 words, and a variable with several
1274 long lines.
1275 (Substitute and define special characters): Test awk special
1276 characters, and put substitution input strings `@foo@' in the
1277 output, to test that no recursion happens; test several other
1278 combinations from Paolo Bonzini.
1280 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
1282 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
1283 that replaced echo with AS_ECHO where this wasn't necessary.
1284 Problem reportd by Ralf Wildenhues.
1285 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
1286 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
1287 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
1289 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1291 * lib/freeze.mk (GREP): Removed, no need to initialize this.
1293 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
1295 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
1296 that traditional Awk lacks 3-arg "split". It has it.
1297 Mention that FS must be a single character, and a few other
1298 99-byte limits of traditional Awk.
1299 Mention that if (i in a) doesn't work with traditional Awk.
1301 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
1303 * tests/autotest.at (BSx641-newline in command):
1304 (BS-BS-newline in command, BSx640-newline in command):
1305 (Newline-CODE-BS-newline in command):
1306 (Single-quote-BS-newline in command):
1307 (Single-quote-newline-BS-newline in command):
1308 Use printf '%s\n' instead of echo, for portability to hosts
1309 where echo interprets backslashes. This will break on hosts
1310 that lack printf, but for now let's assume all such hosts
1311 are dead (if not, we should get reports of test failures).
1313 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
1315 'echo' has some portability problems, when given a first argument
1316 with a leading '-', or when given any argument containing '\'.
1317 Avoid using 'echo' in these cases.
1318 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
1319 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
1320 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1321 * lib/autotest/general.m4 (AT_INIT): Likewise.
1322 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
1323 argument might be unportable.
1324 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
1325 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
1326 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
1327 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
1328 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
1329 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
1330 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
1331 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
1332 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.

1338 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
1339 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
1340 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
1341 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
1342 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
1343 * bin/autoconf.as: Redo verbose flag implementation, as the old
1344 scheme wouldn't work with AS_ECHO.
1345 * lib/autotest/general.m4 (AT_INIT): Likewise.
1346 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
1347 Don't use ECHO_T, since ECHO_N is now reliable.
1348 * lib/autotest/general.m4 (AT_INIT): Likewise.
1349 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
1350 rather than using a here-document to put the script into a file.
1351 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
1352 use AS_ECHO.
1353 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
1354 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
1355 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
1356 bug, but we might as well stop using ECHO_N and ECHO_C internally.
1357 * lib/autotest/general.m4 (AT_SETUP): Likewise.
1358 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
1359 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1360 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
1361 operand, as AS_ECHO requires. Avoid double file name expansion.
1362 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
1363 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
1364 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
1365 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
1366 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
1367 Double-quote strings that would otherwise contain M4 comments.
1368 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
1370 * configure.ac (AC_INIT): Bump to 2.61a.
1371 * NEWS: Likewise.
1373 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
1375 Version 2.61.
1377 * configure.ac (AC_INIT): Bump to 2.61.
1378 * NEWS: Likewise.
1380 * tests/autotest.at (Macro with backslash in a test title):
1381 Comment out for now, as this tests neither fails nor passes
1382 reliably. Problem reported by Ralf Wildenhues.
1384 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
1386 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
1387 in previous change, which caused test failures.
1389 2006-11-16 Stepan Kasal <kasal@ucw.cz>
1391 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
1392 code for --enable, --disable, --with, and --without to...
1393 (_AC_INIT_PARSE_ENABLE): ... a new macro.
1394 * doc/autoconf.texi (Package Options):
1395 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
1397 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
1399 Import these changes from config via gnulib:
1401 2006-11-15 Ben Elliston <bje@gnu.org>
1403 From Josselin Mouette <joss@debian.org>:

1434 Import these changes from texinfo via gnulib:
1436 2006-11-08 Karl Berry <karl@gnu.org>
1438 * build-aux/texinfo.tex (\dopdfimage): look for png, jpg/jpeg/JPG, and
1439 as well as pdf images, since they are supported in pdftex with
1440 no further ado.

1455 * doc/autoconf.texi (External Software): Document that AC_ARG_WITH's
1456 first argument may also contain dots.
1458 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
1460 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
1461 benefit of platforms like Solaris+GCC where it is common to have a
1462 non-working g++ installation.
1464 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1465 and Joel E. Denny <jdenny@ces.clemson.edu>
1466 and Paul Eggert <eggert@cs.ucla.edu>
1468 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs

1472 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
1474 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set

1476 Imported from a similar patch to gnulib by Bruno Haible.
1478 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
1480 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
1481 * doc/autoconf.texi (C Compiler): Document them.
1482 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
1483 New macros, taken from gnulib.
1485 2006-11-07 Paul Eggert <eggert@cs.ucla.edu>

1488 Tandem NonStop Kernel (OSS) cc -O circa 2004, reported by
1489 Matthew Woehlke.
1491 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1493 * tests/torture.at (Configuring subdirectories): Do not skip
1494 Automake 1.10 nor future Automake 11.1 (sic).
1496 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
1497 and Stepan Kasal <kasal@ucw.cz>
1499 Handle special characters in test case titles correctly.

1502 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
1503 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
1504 argument. Extend to check titles printed by ./micro-suite and
1505 ./micro-suite -l and the title in micro-suite.log.
1506 (Backquote in a test title,
1507 Single-quote in a test title,
1508 Double-quote in a test title): Don't expect failure anymore.
1509 (Backslash in a test title): Put a non-whitespace character after the
1510 backslash so that Bourne shells might actually see it as an escape
1511 sequence.
1512 (Brackets in a test title,
1513 Pound in a test title,
1514 Comma in a test title,
1515 Quoted Macro in a test title,

1521 * tests/torture.at (#define header templates): M4-quote this title in
1522 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
1523 The visible effect was a stray [] in the testsuite output.
1525 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1527 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
1528 `trap ... 0' inside a function, for AIX sh.
1530 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
1532 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
1533 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
1534 5363) simply issues a warning when dividing by zero at compile
1535 time. Problem reported by Elias Pipping.
1537 2006-10-26 Eric Blake <ebb9@byu.net>
1539 * THANKS: Update.
1540 * doc/autoconf.texi (Evaluation Macros): Improve the example to
1541 show effect on macros that expand with commas.
1542 Reported by Joel E. Denny.
1544 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
1545 Also work with M4 1.4.8.
1547 2006-10-25 Paul Eggert <eggert@cs.ucla.edu>

1550 Jim Meyering.
1552 2006-10-25 Stepan Kasal <kasal@ucw.cz>

1555 `--force' always rewrites the output file.
1557 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
1559 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm

1566 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
1568 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1569 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
1570 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
1571 reported by Nelson H. F. Beebe for Coreutils 6.4.
1573 * tests/tools.at (autoconf --trace: user macros): Remove test
1574 for tracing multiline macros, since m4 1.4.7a uses a different
1575 way to number lines. Problem reported by Ralf Wildenhues.
1577 2006-10-24 Stepan Kasal <kasal@ucw.cz>
1579 * bin/autom4te.in (handle_m4): Do not redirect stdin to
1580 /dev/null since the heuristics for interactive behaviour was
1581 fixed in CVS m4.
1583 * bin/autom4te.in: With --force, always refresh the output
1584 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
1586 * bin/autoconf.as: Fix the verbose message at the end.
1588 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

1602 * doc/autoconf.texi (Caching Results): Likewise.
1603 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
1604 AC_CACHE_CHECK_INT, since it's no longer public.
1605 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
1606 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
1608 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1610 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
1612 2006-10-19 Eric Blake <ebb9@byu.net>
1614 * lib/m4sugar/m4sugar.m4 (m4_mkstemp): New macro.
1615 (m4_maketemp): Avoid warnings with M4 1.9a.
1616 * lib/emacs/autoconf-mode.el (autoconf-font-lock-keywords): Color
1617 m4_mkstemp.
1618 * doc/autoconf.texi (Redefined M4 Macros): Document m4_mkstemp.

1634 2006-10-14 Stepan Kasal <kasal@ucw.cz>
1636 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
1637 looking for special shell characters.
1638 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
1639 macro defined by AS_VAR_PUSHDEF before passing it as a
1640 parameter.
1641 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
1642 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

1651 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1653 (Imported from Automake.)
1654 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
1655 which incorrectly sets the mode of an existing destination
1656 directory. In some cases the unpatched install-sh could do the
1657 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
1658 system. We hope this is rare in practice, but it's clearly worth
1659 fixing. Problem reported by Alex Unleashed in
1660 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
1661 Also, don't bother to check for -m bugs unless we're using -m;
1662 suggested by Stepan Kasal.
1664 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1666 Import this change from Automake:
1668 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
1669 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
1670 is enabled by default with gnu and gnits strictness.
1671 Report from Bruno Haible.
1673 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
1674 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
1675 gnu and gnits modes.
1677 Import this change from Config:
1679 2006-09-20 Ben Elliston <bje@gnu.org>
1680 * build-aux/config.sub (score, score-*): New.
1682 Import this change from Gnulib:
1684 2006-09-16 Karl Berry <karl@gnu.org>
1685 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
1686 to avoid sectioning errors.
1688 Import these changes from Texinfo:
1690 2006-10-04 Karl Berry <karl@gnu.org>
1691 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
1692 (\quoteexpand): rename to \rquoteexpand.
1693 (\codequoteleft): new def, to look for @set codequotebacktick.
1694 (\lquoteexpand, \quoteexpand): new defs.
1695 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
1696 (\code): must use new \...Char values, since now ` is active.
1698 2006-08-26 Karl Berry <karl@gnu.org>
1699 * build-aux/texinfo.tex (\textdegree): New command.
1701 2006-08-12 Karl Berry <karl@gnu.org>
1702 * build-aux/texinfo.tex (error \box0): smaller font.
1704 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1706 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
1708 2006-10-13 Stepan Kasal <kasal@ucw.cz>
1710 * doc/autoconf.texi (Autoheader Macros): Warn that the text
1711 added to the template can get mangled.
1713 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1715 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
1716 include the default headers, and redefine obstack_chunk_alloc
1717 and obstack_chunk_free. Fixes false failure with glibc.
1719 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
1721 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
1722 for backward compatibility with Libtool 1.5.22. Problem reported
1723 by Ralf Wildenhues.
1725 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1727 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
1728 AC_PROG_CC.
1729 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
1731 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
1733 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
1734 the NonStop platform.
1735 * doc/autoconf.texi (Posix Variants): Likewise.
1736 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
1738 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
1739 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
1740 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
1741 Use a better substitute, by inspecting the output of "ls"
1742 rather than just using ":".
1743 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
1744 rather than AS_EXECUTABLE_P, since we needn't worry about
1745 non-regular files here.
1747 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
1748 due to configuration hassles with this. See Tonya Underwood's report
1749 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
1750 * doc/autoconf.texi (Special Shell Variables): Likewise.
1752 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
1753 Stepan Kasal <kasal@ucw.cz>
1755 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
1756 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
1758 2006-10-11 Stepan Kasal <kasal@ucw.cz>
1760 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
1761 initialization which is not inherited through the environment
1762 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
1763 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
1765 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
1767 * doc/autoconf.texi (Limitations of Usual Tools): Describe
1768 problems with mkdir -p -m.
1770 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
1772 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
1773 comment about ac_cpp_err; it was incorrect, and anyway
1774 ac_cpp_err is being removed below.
1775 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
1776 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
1777 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
1778 nobody uses it.
1779 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
1780 with werror_flag and conftest.err and so forth. This is more
1781 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
1782 and anyway the user shouldn't normally want to see this gorp logged.
1783 Problem reported by Ralf Wildenhues.
1784 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
1785 empty, not 'no', since the rest of the code uses 'test -z'.
1787 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
1789 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1790 Use a single call to AC_DO_TOKENS rather than multiple, for
1791 efficiency.
1792 (_AC_LINK_IFELSE): Test that resulting file is executable.
1793 Problem reported by mwoehlke in
1794 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
1796 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
1797 than creating a file to use with test -x; this is much faster.
1799 2006-10-02 Bruno Haible <bruno@clisp.org>
1801 * lib/autom4te.in (Automake-preselections): Add
1802 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
1804 2006-09-27 Stepan Kasal <kasal@ucw.cz>
1806 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
1807 standard error, `experr' should be used, not `expout'.
1809 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1811 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
1812 fseeko testing program twice; just use the earlier result.
1813 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1814 Set cache var to 'unknown' (not 'no') if leaving the macro unset
1815 still doesn't let the program compile.
1816 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
1817 failed.
1819 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
1820 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
1821 include it, without including anything else.
1822 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
1823 expressions.
1824 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
1826 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1828 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
1829 `error.h', and include it, for a `error_at_line' prototype.
1830 Use a nonempty format string in the link test.
1831 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
1832 for a declaration of wait3.
1834 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1836 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
1837 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
1838 can apply to constants too, and that it checks for macro defns.
1839 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
1840 and simply cast the identifier to void. This handles structure
1841 values. Problem reported by Ralf Wildenhues.
1842 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
1844 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1846 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
1847 structure, and function symbols.
1849 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1851 * tests/semantics.at (AC_CHECK_MEMBERS): Also test with a struct
1852 member.

1864 warnings (uninitialized value).
1865 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
1866 present.
1867 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add
1868 parentheses.

1953 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
1954 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now

1977 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
1978 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
1979 accept files with extension `.f'. For consistency, also prefer
1980 xlf over f77.
1981 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug

2056 broken lex libraries like native ia64-hp-hpux11.22; see
2057 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
2058 work around the problem by preferring an empty LEXLIB to -lfl or
2059 -ll. Let the user set LEXLIB='' to indicate no library needed.

2291 reported by Keith Marshall. Also, don't bother with builddir2,
2292 since it shouldn't be needed any more.

2333 * doc/autoconf.texi: Be more consistent about using @acronym with
2334 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
2335 quite right (it talked about "OSF/Tru64", even though the
2336 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
2337 and it even mentioned "OSF 4"!) and at this point there's little
2338 reason to talk about OSF any more, since it died in 1994.
2339 (Specific Compiler Characteristics): Simplify example of
2340 negative-size array.
2341 (File Descriptors): Reorder to make the text flow better.
2342 Remove joke about "appreciate the various levels"; I didn't get it.
2343 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
2344 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
2345 (File Descriptors, Limitations of Usual Tools):
2346 Tone down the advice against renaming or removing open files.
2347 (Limitations of Usual Tools): Add a new section, on 'rm'.
2349 2006-06-26 Stepan Kasal <kasal@ucw.cz>
2351 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
2352 -lXt in LIBS, idea from Karsten Hopp; this was due since
2353 this change:
2355 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2356 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2357 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2358 (which belong to Xt, not X itself). See Debian bug 327655.
2360 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2362 * configure.ac (AC_INIT): Bump to 2.60a.
2363 * NEWS: Update.
2365 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2367 Version 2.60.
2369 * configure.ac, NEWS: Update.
2371 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2373 * config/texinfo.tex: Sync from upstream.
2375 * bin/autom4te.in (handle_traces): Transform the `@S|@'
2376 quadrigraph correctly in traces.
2378 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
2379 Fix typos.
2381 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
2382 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
2383 not defined.
2384 * doc/autoconf.texi (Changed Directory Variables): New node,
2385 to document the whole `datarootdir' business a bit better.
2386 * NEWS: Update.
2387 * tests/torture.at (datarootdir workaround): Extend test.
2388 Prompted by report by Alexandre Julliard.
2390 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
2392 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
2393 when using default mode of IBM C 6 for AIX. Problem and two-line
2394 fix reported by Larry Jones.
2396 2006-06-22 Alexandre Julliard <julliard@winehq.org>
2398 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
2399 about literal '${datarootdir}' if a definition is found in the
2400 output file.
2402 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
2404 * NEWS: Use "M4" rather than "m4" when appropriate.
2405 Problem reported by Eric Blake.
2406 * doc/autoconf.texi: Likewise.
2407 Use @acronym around BSD, GCC, and GNU when appropriate.
2408 (Why GNU M4): Renamed from "Why GNU m4".
2409 (Redefined M4 Macros): Mention that Posix
2410 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
2411 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
2412 to int.
2414 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2416 * bin/autom4te.in (handle_output): Do not forbid the empty
2417 pattern.
2418 * tests/tools.at (autoconf: the empty token): New test.
2420 2006-06-20 Stepan Kasal <kasal@ucw.cz>
2422 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
2423 calls, so that we do not care whether they are LIFO or FIFO;
2424 in the m4_wrap, do not check which diversion is the topmost
2425 one, just check that the stack is balanced at the end.
2426 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
2427 base diversion forever--pop the previous diversion before
2428 opening the new one; consequently, remove the m4_wrap call.
2429 * lib/autotest/general.m4 (AT_INIT): Likewise.
2430 * tests/m4sugar.at: Do not use
2431 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
2433 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
2434 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2436 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
2437 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
2438 Rework example of m4wrap token-pasting trouble so that it doesn't
2439 care whether it's LIFO or FIFO.
2440 Fix some "contrary to"s that are awkward in English.
2442 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2444 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
2445 to `yes' instead of `int$1_t' if the type is found, for more
2446 consistent configure output (where $1 is the number of bits).
2447 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
2448 Suggested by Bruno Haible.
2450 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
2451 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
2452 with system headers. Report by Bruno Haible.
2454 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2456 * config/config.guess, config/config.sub: Sync from upstream.
2458 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
2459 in order to avoid picking up an older installed frozen m4sh.m4f.
2460 Besides an outdated shell startup, this could have been created
2461 by an earlier M4 version with incompatible frozen file format.
2463 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
2465 * README: Recommend m4 1.4.4 instead of 1.4.3..
2466 * doc/autoconf.texi: Likewise.
2467 (Special Chars in Names): Say that $(.FOO) is portable, as
2468 suggested by Stepan Kasal.
2469 (Installation Directory Variables, Build Directories):
2470 (Automatic Remaking, Subdirectories, Fortran Compiler):
2471 (Making testsuite Scripts, Defining Directories):
2472 Quote variable usages better.
2473 (Making testsuite Scripts): Add clean-local rule to makefile
2474 snippet, by Eric Blake.
2475 (Installation Directory Variables): Fix table item font.
2476 Reword slightly to clarify. Generalize advice about
2477 not using special characters to include all file-related
2478 vars, not just VPATH.
2479 (Special Chars in Variables): Warn about special characters in
2480 $(srcdir) too.
2481 (Assignments): Clarify default-value example as suggested by
2482 Ralf Wildenhues in
2483 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
2484 (Special Shell Variables): Note leading ./ or ../, as suggested
2485 by Eric Blake.
2486 (Limitations of Builtins): Under cd, warn about CDPATH.
2487 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
2488 Ralf Wildenhues.
2490 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2492 * doc/autoconf.texi (Configuration Actions): Remove duplicate
2493 `@var', for texi2html.
2494 (Systemology): Some more word wrapping, for DVI output.
2495 (autom4te Invocation): The short option for `--melt' is `-M',
2496 not `-m'.
2498 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
2500 * doc/autoconf.texi: More formatting and English tweaks,
2501 many suggested by Ralf Wildenhues.
2502 Reword to avoid "@code{...}'s" and the like, since it's ugly
2503 with Emacs info mode. discontents -> woes.
2504 Put a few "will"s back. time stamp -> timestamp.
2505 side-effect -> side effect.
2507 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
2509 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
2510 Warn about $@ not persisting. Problem reported by Julien Danjou in
2511 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
2512 (Special Chars in Names): Renamed from Leading _ in Macro Names.
2513 Mention other special chars, too.
2515 2006-06-14 Eric Blake <ebb9@byu.net>
2517 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
2519 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
2521 * doc/autoconf.texi: Some systematic minor improvements, as
2522 follows. Use "makefile" when talking about makefiles
2523 generally (which might be named "makefile" or "Makefile" or even
2524 "foo.mk"), "Makefile" when talking about a specific makefile
2525 called "Makefile". This unclutters the text from weird quotes
2526 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
2527 values" rather than "@var{foo}s" and similar constructs containing
2528 "}s". Use "Make rules" rather than "Makefile rules". Minor
2529 English-language improvements. Change the prefix "sub-" to "sub"
2530 and "re-" to "re".
2531 Put blank lines around examples more consistently.
2532 Avoid "rather" and "very" as intensifiers.
2533 Avoid "will" as an auxiliary.
2534 (Limitations of Make): Split this node into....
2535 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
2536 (Leading _ in Macro Names, Backslash-Newline-Newline):
2537 (Backslash-Newline Comments, Long Lines in Makefiles):
2538 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
2539 (obj/ and Make, make -k Status, VPATH and Make):
2540 (VPATH and Double-colon, $< in Explicit Rules):
2541 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
2542 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
2543 New nodes, resulting from splitup of Limitations of Make.
2544 All cross-references changed. Raise the top node from
2545 a section to a chapter, and all subnodes accordingly.
2546 Redo the introductory wording to match the new organization.
2547 (Installation Directory Variables): Use an example that is
2548 closer to what Autoconf actually does. Mention that VPATH's
2549 value should not contain metacharacters or white space.
2550 (Fortran Compiler): Fix a VPATH bug in an example.
2551 (Leading _ in Macro Names): Mention that this problem is no longer
2552 of practical concern.
2553 (VPATH and Make): Reword the advice to make it clearer
2554 that Autoconf and Automake support VPATH in non-GNU make, but
2555 many packages have bugs in this area.
2556 ($< in Explicit Rules): Refer to Build Directories rather
2557 than using a (non-VPATH-safe) example.
2558 (Automatic Rule Rewriting): Mention the sort of disaster that
2559 can ensue with Solaris-style rule rewriting with VPATH.
2561 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2563 * doc/install.texi (Compilers and Options): Weaken the
2564 suggestion to use GNU make for VPATH builds.
2566 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
2567 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
2569 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
2570 in regular expression.
2572 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2574 * doc/autoconf.texi (Installation Directory Variables):
2575 Drop extra @samp from `@table @samp' item.
2576 (Limitations of Usual Tools): Comment fix.
2577 Do not nest @samp just to point to other table items.
2578 (Writing testsuite.at) <AT_CHECK>: The second argument to
2579 `@dvar' is already @samp'ed.
2580 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
2581 do not use @var in the second argument.
2583 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
2585 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
2586 $as_shell.exe too. Problem reported by Andreas Buening in
2587 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
2589 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2591 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
2592 `unused variable' compiler warning, for `-Wall -Werror'.
2593 Reported by Jaap Haitsma in
2594 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
2596 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
2598 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
2599 case the compiler dumps core. Problem reported for
2600 OpenServer 5.0.7 by Tim Rice in
2601 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
2602 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2603 Likewise.
2605 2006-06-06 Tim Rice <tim@multitalents.net>.
2607 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
2608 "ERROR" only shows up in "make check" output if there is an
2609 error.
2611 2006-06-06 Eric Blake <ebb9@byu.net>
2613 * tests/tools.at (automatically allowed tokens): Fix typo.
2615 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2617 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
2619 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
2620 typically overflows on x86 CPUs, even though the C standard
2621 requires otherwise.
2623 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2625 * configure.ac (AC_INIT): Bump to 2.59e.
2626 * NEWS: Update.
2628 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2630 Version 2.59d.
2632 * config/texinfo.tex: Sync from upstream.
2634 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
2635 seen, invoke libtoolize with `--ltdl' argument.
2636 * lib/autom4te.in (Autoreconf-preselections): Adjust.
2637 * NEWS: Update.
2638 Suggested by Eric Blake.
2640 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2642 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
2643 reported by Ralf Wildenhues.
2644 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
2646 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2648 * THANKS: Update.
2650 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2652 * doc/autoconf.texi: Modernize some of the references to Solaris.
2654 2006-06-05 Stepan Kasal <kasal@ucw.cz>
2656 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
2657 message issued by AC_REQUIRE.
2658 * tests/m4sugar.at: Check m4_require's error message.
2659 * tests/base.at: Check AC_REQUIRE's error message.
2660 * tests/local.at (AT_CHECK_M4): New macro, almost identical
2661 to...
2662 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
2663 AT_CHECK_M4.
2664 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
2665 `expout' as the last parameter.
2666 * tests/tools.at: Adapt to the above change.
2668 2006-06-04 Stepan Kasal <kasal@ucw.cz>
2670 * doc/autoconf.texi (Limitations of Usual Tools): Correct
2671 information about race-free implementations of mkdir.
2673 2006-06-04 Eric Blake <ebb9@byu.net>
2675 * bin/autoreconf.in (help): Document M4 environment variable.
2676 * bin/autoconf.as (Usage): Likewise.
2677 * bin/autom4te.in (help): Likewise.
2678 * doc/autoconf.texi (autom4te Invocation): Likewise.
2680 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
2682 * NEWS: GNU make now recommended for VPATH builds.
2683 Mention that some macros are now documented to be obsolescent.
2684 * doc/autoconf.texi:
2685 Prefer "current" to "modern" to describe
2686 currently-used (albeit perhaps old-fashioned) hosts.
2687 Mention which ancient features no longer need to be worried about.
2688 setgid -> set-group-ID
2689 setuid -> set-user-ID (these are the Posix terms)
2690 Fix some misuses of "only".
2691 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
2692 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
2693 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
2694 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
2695 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
2696 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
2697 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
2698 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
2699 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
2700 Mention that these macros are obsolescent.
2701 (Installation Directory Variables): shall -> should
2702 (File Descriptors): Mention that 0, 1, 2 might get reopened.
2703 Mention that it's now safe to use 3 and 4.
2704 (Limitations of Usual Tools): cp -r is now specified by Posix.
2705 Omit longwinded and obsolescent discussion of cp -f.
2706 Modernize discussion of expr, ls.
2707 (Limitations of Make): Modernize discussion of VPATH builds.
2708 Mention $? as a workaround in some cases.
2709 * doc/install.texi (Basic Installation):
2710 Mention "./configure; make; make install" first. Be more
2711 specific about why this file is generic. Remove unnecessary
2712 parens. Remove misleading "only". Remove obsolete advice
2713 about csh. Don't say "configure" takes awhile; say it
2714 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
2715 and CC=c99 rather than CC=c89, as these are blessed by current
2716 Posix. Recommend GNU make if doing a VPATH build.
2718 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
2720 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
2721 examples involving shell prompts.
2723 2006-06-02 Stepan Kasal <kasal@ucw.cz>
2724 and Paul Eggert <eggert@cs.ucla.edu>
2726 * doc/autoconf.texi (Here-Documents): Add details about the
2727 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
2728 use "here-documents" instead of "here documents".
2730 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2732 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
2734 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
2736 * doc/autoconf.texi (File System Conventions): Warn about ":"
2737 anywhere in directory names.
2739 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
2741 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
2742 about quoting the case statement, just in case.
2743 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
2744 was fixed in ksh93g; reported by Ralf Wildenhues.
2746 2006-05-31 Stepan Kasal <kasal@ucw.cz>
2748 * doc/autoconf.texi (System Services): Do not document
2749 overriding EXEEXT via ac_cv_exeext=ext.
2750 (Particular Programs) <AC_PROG_MKDIR_P>:
2751 Document that ${MKDIR_P} understands --.
2752 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
2753 comment.
2755 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2757 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
2758 argument with leading hyphen. Problem reported by Paul Eggert.
2760 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2762 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
2763 about quoting ac_try: quote all of it, if any of it seems suspicious.
2764 This means we don't have to worry about ${ or sed any more.
2765 Also, double-quote the case statement, to work around misuses via
2766 underquoting as reported by Ralf Wildenhues in
2767 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
2768 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
2769 undocumented and dangerous macro.
2770 Problem reported by Ralf Wildenhues in
2771 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
2773 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2775 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
2776 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
2777 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
2779 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2781 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
2782 since evidently some packages rely on the old, broken behavior.
2783 Problem reported by Ralf Wildenhues in
2784 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
2785 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
2786 pre-2006-05-26 definitions, but leave in the comments that
2787 these macros are dangerous and should not be used.
2788 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
2789 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
2790 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
2791 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
2792 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
2794 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2796 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
2797 the use of 'tr', since this is our only use of 'tr'.
2799 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2800 and Paul Eggert <eggert@cs.ucla.edu>
2802 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2803 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2805 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2807 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2808 the output file in the `${datarootdir}' test.
2810 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2811 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2813 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2814 mention of `datarootdir' in the input file(s), but literal
2815 `${datarootdir}' in the output file, and we haven't warned yet,
2816 then warn as well: the user may have (erroneously) used
2817 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2818 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2819 * tests/torture.at (datarootdir workaround): Extend this test.
2820 * NEWS: Update.
2822 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2823 and Paul Eggert <eggert@cs.ucla.edu>
2825 * doc/autoconf.texi (autoheader Invocation): The first argument to
2826 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2827 alternatives and clear up the language a bit.
2829 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2831 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2832 ac_config_guess, ac_config_sub, ac_configure.
2833 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2834 Fix typo that prevented an unnecessary space from being removed.
2835 Problems reported by Ralf Wildenhues in:
2836 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2838 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2840 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2841 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2842 Don't use the term "thread-safe" to talk about mkdir race
2843 conditions, since the problem is more a process than a thread
2844 issue. Problem reported by Stepan Kasal in:
2845 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2846 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2847 the test for 'install' more closely. Look at MKDIR_P first.
2848 Look in the PATH, and at /opt/sfw/bin.
2849 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2850 Don't bother to try mkdir -p, since we already check mkdir --version;
2851 just look at the version number. (There's no easy way to check
2852 for race-free implementations.)
2853 * tests/tools.at (autoconf: subdirectories): Adjust to above
2854 changes, since MKDIR_P now might end in "/mkdir -p".
2856 * doc/autoconf.texi (autoheader Invocation): Mention that the
2857 first arg of AC_DEFINE_UNQUOTED must be a literal.
2858 Problem reported by Ben Pfaff in
2859 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2861 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2862 * doc/autoconf.texi (Special Chars in Variables): New section.
2863 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2864 (Installation Directory Variables): Quote $(datadir) better.
2865 (Limitations of Builtins): Describe some of eval's trickiness.
2867 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2868 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2869 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2870 in front of every arg, not just trailing args. Quote apostrophes.
2871 (_AC_EVAL_ECHO): New macro.
2872 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2873 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2874 removed.
2875 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2876 exposed by quoting of eval argument. Put the command on line line
2877 so it logs better.
2878 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2879 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2880 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2881 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2882 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2883 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2884 Use eval more safely.
2885 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2886 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2887 to be replaced.
2888 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2889 lines, exposed by quoting of eval argument.
2891 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2892 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2894 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2895 initialization of `ac_cv_exeext', do not override it if it was
2896 already set, unless it was set to `no', for compatibility with
2897 Autoconf-2.13, and comment this.
2898 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2899 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2900 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2901 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2902 Document that this test may be overridden by setting
2903 `ac_cv_exeext'.
2905 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2907 Revert these two patches:
2909 2006-04-06 Eric Blake <ebb9@byu.net>
2910 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2911 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2912 2006-04-01.
2914 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2915 Clean up _AC_COMPILER_EXEEXT* macros.
2916 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2917 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2918 ac_file to the name of the default output file and call
2919 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2920 initial `rm' of the candidate files...
2921 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2922 the same list in subsequent `rm' calls, and for the temporary
2923 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2924 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2925 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2926 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2927 no longer needed) by libtool. Make it a cache check.
2928 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2929 copied here by mistake.
2930 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2931 _AC_COMPILER_EXEEXT.
2932 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2933 _AC_COMPILER_OBJEXT directly.
2934 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2936 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2938 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2939 Fix description of how the buggy `sed' works.
2941 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2943 Sync from Automake:
2945 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2946 ENOLCK. Only mention `make -j' when applicable. Only raise
2947 fatal errors when `make -j' is involved. Improve error message.
2949 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2951 * doc/autoconf.texi (Here-Documents): We now know more about
2952 the variable expansion in here documents bug.
2953 Thanks to Tim Rice and Stepan Kasal.
2955 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2956 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2958 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2960 * tests/autotest.at (Multiline command from M4 expansion):
2961 No failure to be expected if the shell quotes newlines in
2962 commands in the `set -x' output. Report by Tim Rice.
2963 * THANKS: Update.
2965 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2967 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2968 expansion in the here-documents used by config.status, as that
2969 runs afoul of the Korn shell version M-12/28/93d bug described in
2970 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2971 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2972 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2974 2006-05-23 Jim Meyering <jim@meyering.net>
2976 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2977 Fix typo introduced with 2006-04-02 change. It reversed the sense
2978 of the test.
2980 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2982 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2983 ac_dB slightly, to save bytes in the script.
2984 Max out at 50 lines, rather than 96; this is more likely
2985 (though not guaranteed) to avoid obscure 'sed' failures.
2987 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2989 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2990 `tr -d -' as bad option argument. Work around this by deleting
2991 an unrelated character.
2992 Report by Tim Rice <tim@multitalents.net>.
2994 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2995 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2996 Stepan Kasal <kasal@ucw.cz>
2998 * doc/autoconf.texi (Particular Programs): Do not promise that
2999 we always prefer the GNU version of the program, and that we
3000 search according to PATH; both rules can have exceptions.
3001 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
3002 AC_PROG_SED. Move descriptions of limitations
3003 to the Limitations of Usual Tools section.
3004 (Limitations of Usual Tools) <sed>: Mention script length
3005 limitations with Solaris /usr/ucb/sed.
3006 <grep>: Fix wording for empty alternative. Mention that -c and
3007 -l should not be combined, and that -E and -F should not be
3008 combined.
3010 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3011 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3013 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
3014 limits in Solaris 8 /usr/ucb/sed by testing a long script.
3016 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3018 * doc/autoconf.texi (Defining Symbols): Literal parameter of
3019 AC_DEFINE is now passed to m4_pattern_allow.
3020 * NEWS: Mention that; likewise for AC_SUBST.
3021 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
3022 the parameter to m4_pattern_allow.
3023 * tests/tools.at: Add a check for that.
3025 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3027 * lib/autoconf/status.m4: Fix typos.
3029 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3031 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
3032 only the files that this macro generates.
3034 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3036 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
3037 the HP-UX sed limitation of 99 commands, labels do not count.
3038 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
3039 in the comment.
3040 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
3042 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3044 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3045 Import the following fix from coreutils:
3047 2006-01-13 Jim Meyering <jim@meyering.net>
3049 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
3050 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
3051 not double-quote uses of that variable, to accommodate the rare
3052 case in which getmntent is available in none of the libraries
3053 checked. This happens at least on FreeBSD 5.0.
3055 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
3057 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
3058 ac_config_guess, ac_config_sub, and ac_configure, since evidently
3059 some other programs unwisely rely on these undocumented vars.
3060 But put in warning comments about them.
3061 Problem reported by Ralf Wildenhues in
3062 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
3063 * NEWS: Document that these variables are intended to go away.
3065 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3067 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
3068 and set the language to C++ (analogous to the equivalent Fortran
3069 tests).
3071 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
3072 * doc/autoconf.texi (C++ Compiler): Document it.
3073 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
3074 * NEWS: Update.
3076 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
3078 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
3079 that caused config.status to generate 100-command sed scripts; the
3080 portable limit is 99.
3082 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3084 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
3085 variable `ac_d' instead of `d' to avoid infringing namespace.
3086 Report by Ralf Menzel.
3088 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
3090 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
3091 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
3092 * tests/tools.at (autoconf: subdirectories): New test, taken from
3093 the corresponding problem report by Ralf Wildenhues in:
3094 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
3096 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
3097 Quote some uses of shell variables if they might suffer unexpected
3098 globbing. This doesn't fix all instances of quoting problems that
3099 I found, just the easy ones that look safe.
3100 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
3101 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
3102 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
3103 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
3104 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
3105 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
3106 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
3107 Likewise.
3108 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
3109 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
3111 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3113 * bin/autoreconf.in ($help): Reword according to the manual.
3114 Suggested by Olly Betts.
3116 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
3117 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3119 * bin/autoreconf.in: Pass the directory argument to
3120 `require_configure_ac'. Fix comment.
3121 * tests/torture.at (Configuring subdirectories): Expose this.
3122 Reported by Olly Betts.
3124 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3126 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
3127 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
3128 Automake as follows:
3130 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
3131 `$configure_in' instead of `configure.in', to preserve
3132 directory component.
3134 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3136 * config/config.guess, config/config.sub, config/texinfo.tex,
3137 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
3139 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
3141 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
3142 test for C99 conformance; (bool) 0.5 is an integer constant
3143 expression, but (bool) -0.5 is not. Problem reported by Fedor
3144 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
3146 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
3148 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
3149 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
3150 Warn about obsolete install-sh files. Remove stray sentence
3151 fragment and fix cross reference.
3152 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
3153 install -d; this undoes the 2006-05-10 change.
3154 (MKDIR_P): Mark with AN_MAKEVAR.
3155 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
3156 that we don't require $INSTALL to be thread-safe. Move comments
3157 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
3158 of AC_PROG_INSTALL. Output a message saying that we're checking
3159 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
3160 MKDIR_P instead of AC_SUBST.
3161 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
3162 Special magic for MKDIR_P, too.
3163 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
3164 a dnl.
3165 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
3167 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
3169 Sync from Automake, as follows:
3171 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3172 * config/install-sh: Initialize IFS, so field splitting isn't
3173 turned off later.
3174 * config/mkinstalldirs: Likewise.
3175 * config/missing: Remove superfluous quotes. Replace all uses of
3176 `[' by `test', for consistency, and for..
3177 * config/missing (sed_minuso, sed_output): New variables.
3178 (autom4te, help2man, makeinfo): Use them. Unifies detection of
3179 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
3180 Fixes `missing' to detect `--output' for help2man. Fixes
3181 PR automake/483. Report by Dennis J. Linse.
3182 (autom4te): Document in `missing --help'.
3184 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3186 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
3187 * config/install-sh: Don't use 'path' to talk about file names,
3188 as per GNU coding standards. Close a race condition reported by Ralf
3189 Wildenhues and Stepan Kasal. There is still a race condition
3190 on hosts that predate Posix 1003.1-1992, but we can't help this.
3191 Don't mishandle weird characters like space on pre-Posix hosts.
3192 Invoke mkdir at most once per dir arg on pre-Posix hosts.
3193 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
3194 AC_PROG_MKDIR_P from AS_MKDIR_P.
3195 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
3196 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
3197 earlier editions are not (including Automake 1.8.3).
3198 Do not suggest mkinstalldirs for thread-safety.
3199 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
3200 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
3201 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
3202 presence of special characters and race conditions.
3203 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
3204 in Autoconf's name space.
3206 2006-05-10 Bruno Haible <bruno@clisp.org>
3207 and Paul Eggert <eggert@cs.ucla.edu>
3209 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
3210 from Automake with minor changes.
3211 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
3213 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3215 * config/install-sh: Update to Automake CVS version, as follows:
3216 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3217 * lib/install-sh: Simplify the expr implementation of dirname.
3218 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
3219 * lib/install-sh: Handle --, and diagnose unknown options.
3221 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3223 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
3224 `./autom4te' to create `./testsuite', since the `all' target
3225 will ensure its presence, but `installcheck' should not create
3226 the uninstalled wrappers.
3228 * tests/torture.at (Unusual Automake input files): Skip if we
3229 detect automake < 1.8.
3231 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3233 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
3234 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
3235 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
3236 * NEWS: Update.
3238 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3240 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
3241 munge (multiple) white space and other oddities.
3242 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
3243 single quotes in variable assignment.
3244 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
3245 and similar failures by adding multiple spaces, tabs, and other
3246 special characters.
3247 Report and different test suggested by Francesco Romani
3248 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
3250 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
3251 single quotes, we only need to search for single quotes; this
3252 both simplifies the search pattern, and makes us less
3253 susceptible to `echo' variations for arguments not containing
3254 single quotes.
3255 (_AC_ARG_VAR_VALIDATE): Likewise.
3257 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3259 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
3260 `$*' and IFS concatenation issue with traditional shells and
3261 bash-2.04. Report by Seanster@Seanster.com.
3263 2006-05-03 Bruno Haible <bruno@clisp.org>
3265 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
3266 precisely which Mac OS X versions have the od problem.
3268 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3270 * doc/autoconf.texi: Use @option systematically.
3272 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3273 and Bruno Haible <bruno@clisp.org>
3275 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
3276 about 'od'.
3277 (Integer Overflow): Mention the special case of integer division
3278 overflow.
3280 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3282 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
3283 traditional shells like the Solaris one that do not use the
3284 first IFS character for assembling `$*'.
3285 Prompted by a related report from autoconf_bug@nro.ca.
3287 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
3288 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3290 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
3291 Mention more problems with the -e option.
3293 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3295 * NEWS: Typo.
3296 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
3298 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
3299 in URLs to improve DVI formatted output (requires texinfo 4.6).
3300 (System Services, Systemology, Shellology): Likewise.
3301 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
3302 output.
3304 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
3305 continuous text.
3306 (Runtime): Fix macro argument names to match description:
3307 `action-if-found' -> `action-if-true' and similarly.
3308 (Obsolete Macros): Likewise.
3309 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
3310 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
3311 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
3313 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3315 * doc/autoconf.texi (Limitations of Make): Clean up markup.
3317 * ChangeLog: Typo.
3318 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
3319 DVI output.

3324 /bin/sh set unsorted output.
3325 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
3326 * tests/local.at: Likewise.
3328 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
3330 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
3331 (Integer Overflow, Null Pointers, Buffer Overruns):
3332 (Floating Point Portability, Exiting Portably): New sections.
3333 (Writing Test Programs): Fix some langauge. Recommend exiting
3334 with status 1, not merely nonzero. Clarify exit declaration.
3335 (Run Time): Move C exit status stuff to new Exiting Portably section.
3336 (Systemology): Mention Posix and levenez. Update v7 reference.
3337 (Portable Shell): Mention the Posix shell.
3339 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3341 * bin/autoconf.as (me): Replace by as_me.
3343 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
3345 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
3346 since as_me isn't set yet.
3348 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3350 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
3351 a few minor bugs in this area.
3353 * doc/autoconf.texi (Programming in M4sh): Comment out the
3354 documentation of AS_BASENAME, for now.
3355 (Shell Substitutions): Do not use AS_DIRNAME in an example.
3356 (Limitations of Builtins) <basename>: Do not refer to
3357 AS_BASENAME.
3358 * bin/autoconf.as (me): Don't use AS_BASENAME.
3359 (dir): Remove the unused variable.
3360 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
3361 AS_DETECT_REQUIRED. All uses changed.
3362 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
3363 All uses changed.
3364 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
3365 (AS_BASENAME): Use "basename --" to protect against leading "-".
3366 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
3367 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
3368 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
3369 (_AS_DIRNAME_PREPARE): Likewise.
3370 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
3371 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
3372 (AS_DIRNAME): Use "dirname --".
3374 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3376 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
3377 of "run time" and "run-time" changed to "runtime", for consistency.
3378 * lib/autoconf/fortran.m4: Likewise (in comment).
3379 * lib/autoconf/functions.m4: Likewise.
3380 * lib/autoconf/general.m4: Likewise.
3381 * lib/autoconf/headers.m4: Likewise.
3383 * doc/autoconf.texi (Run Time): Document the exit status situation
3384 with more accuracy and detail.
3386 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3388 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
3389 Archive is not officially `GNU' any more. Update URL.
3390 (Defining Directories): Likewise
3391 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
3393 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3395 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
3396 newline from the `trap' code to finish `config.log'; the NetBSD
3397 /bin/sh resets the exit status after an empty command, as
3398 documented in doc/autoconf.texi.
3399 Reported by Dalibor Topic <robilad@kaffe.org>.
3401 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
3403 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
3404 Suggested by Bruno Haible.
3406 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
3408 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
3409 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
3410 Instead, just list the shells that we know work.
3411 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
3412 changed. Be more cautious about the _cv_ variable.
3413 * tests/tools.at (Syntax of the shell scripts): Check the
3414 _cv_ variable once, at first, to avoid an internal autoconf error
3415 when sh -n does not work.
3417 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3419 * lib/Autom4te/FileUtils.pm: Sync from Automake.
3421 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
3423 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
3424 use ">&-" since we're only 99.999% sure that this is portable,
3425 and since the MinGW bug is fixed in a different way.
3426 * lib/autotest/general.m4 (AT_INIT): Likewise.
3428 2006-04-16 Stepan Kasal <kasal@ucw.cz>
3430 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
3431 before opening config.log, to avoid hitting a bug on MinGW.
3433 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
3435 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
3436 AS_MESSAGE_LOG_FD before reopening it onto the log file.
3437 This works around a MinGW bug reported by Eric Paire.
3438 Make sure that all writes to the log file append to it,
3439 rather than possibly losing data.
3440 * lib/autotest/general.m4 (AT_INIT): Likewise.
3442 2006-04-14 Stepan Kasal <kasal@ucw.cz>
3444 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
3445 description.
3447 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3449 * NEWS: Update.
3451 * configure.ac (AC_INIT): Bump to 2.59d.
3453 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3455 Version 2.59c.
3457 * Makefile.maint (news-date-check): Do not require a leading `*'
3458 before the release date in NEWS.
3460 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3461 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3463 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
3464 the instantiated file do not contain the string 'datarootdir'
3465 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
3466 @mandir@, replace the reference '${datarootdir}' by the value.
3467 * tests/torture.at (datarootdir workaround): New test.
3468 * NEWS: Advertise this temporary fixup.
3469 Based on a patch by Bruno Haible, reported and analyzed by
3470 Paul Eggert and Noah Misch.
3472 2006-04-12 Eric Blake <ebb9@byu.net>
3474 * tests/autotest.at (Debugging a failed test): Fix comment.
3476 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3478 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
3479 all the changes since 2006-04-07.
3481 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3483 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
3484 succeeded, but `ln -s file dir' failed, take care to remove the
3485 leftover target before the next test, to prevent its spurious
3486 failure; also make sure `ln file dir' works before selecting it.
3487 Thanks to Keith Marshall for pointing this out.
3488 * THANKS: Update.
3490 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
3491 assignments in `at_debug_args', so that we put them correctly
3492 in the `run' script.
3493 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
3494 Reported by Eric Blake.
3496 2006-04-11 Eric Blake <ebb9@byu.net>
3498 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
3499 top-level tests after micro-suite has been run. Used in...
3500 (Debugging a successful test, Debugging script and environment),
3501 (Debugging a failed test): ...these new tests. The first of these
3502 is fixed by...
3503 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
3504 macro, split out from...
3505 (AT_INIT): ...here, so that using -d also generates a run script.
3506 Document that -d inhibits top-level logging.
3507 * doc/autoconf.texi (testsuite Invocation): Document that -d only
3508 inhibits top-level logging; debug scripts are created.
3510 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
3511 check.
3512 * tests/autotest.at (Empty test, Empty check): New test to check it.
3514 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
3515 from gcc.
3517 2006-04-10 Stepan Kasal <kasal@ucw.cz>
3519 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
3520 the files if a problem appears. Make the empty *.at files
3521 read-only, too. Proposed by Ralf Wildenhues.
3523 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3525 * config/Makefile.am: Add comment to force updated Makefile.in.
3527 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
3528 space only patch to this file, this patch causes the Makefile.in
3529 files that include freeze.mk to be updated, and thus have a
3530 newer time stamp again, which in turn makes a pristine CVS
3531 checkout have correct time stamps.
3533 * Makefile.maint (cvs-sv): New macro, to be used..
3534 (config.guess-url_prefix, config.sub-url_prefix)
3535 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
3536 point to CVS text checkout of Gnulib files.
3537 (copyright-check): Bump current year.
3538 (announcement): Do not hard-wire `./announce-gen'.
3539 (cvs-update): Propagate failures of `cvs' and `move-if-change'
3540 correctly.
3541 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
3542 `chmod +x'.
3543 (wget_files): Update config.guess, config.sub, texinfo.tex by
3544 `wget-update', now that their URLs work again.
3546 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3548 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
3549 Problem noted by Paul D. Smith.
3551 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3553 * doc/autoconf.texi: Remove unused words from word list.
3554 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
3555 .x-sc_trailing_space: New files.
3557 * doc/standards.texi: Sync from gnulib.
3559 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
3560 `LIBOBJDIR' as experimental.
3562 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
3563 with a target directory; it's internally implemented as `cp'
3564 anyway, but since Autoconf advertises the possibility to use
3565 a target directory when LN_S is `ln -s', we need to find out.
3566 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
3567 analyzed by Keith Marshall <keith.marshall@total.com>.
3569 * THANKS: Update.
3571 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3573 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
3574 confdefs.h as-is. In general, if it has backslash-newline or the
3575 like, then it doesn't work either to sort or to remove empty
3576 lines.
3578 2006-04-09 Stepan Kasal <kasal@ucw.cz>
3580 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
3582 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
3584 * lib/autom4te.in (Automake-preselections): Preselect
3585 _AM_SUBST_NOTMAKE.
3587 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3589 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
3590 apostrophe within a single-quoted string, as this is the usual
3591 tradition and is easier to read than '"'"'. Don't rely on the
3592 shell treating "$/" like '$/'. Use a more-consistent indenting
3593 style for the trap.
3595 2006-04-09 Eric Blake <ebb9@byu.net>
3597 * tests/autotest.at (Backquote command substitution),
3598 (Multiline backquote command substitution): Remove mistaken
3599 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
3600 applied...
3601 (Parenthetical command substitution, Multiline parenthetical
3602 command substitution): here.
3604 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3606 Import macros from gnulib (often changing their name).
3608 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
3609 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
3610 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
3611 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,
3612 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T,
3613 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
3614 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
3615 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
3616 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
3617 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
3618 The manual mentions Gnulib more prominently.
3619 * doc/autoconf.texi (Gnulib): New node.
3620 (Pointers): Add Gnulib URL.
3621 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
3622 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
3623 Gnulib section.
3624 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
3625 suggest a #define rather than a typedef for _Bool, and mention
3626 Gnulib rather than trying to substitute stdbool code.
3627 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
3628 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
3629 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
3630 AC_STRUCT_DIRENT_D_TYPE.
3631 (Particular Types): Mention stdint.h and inttypes.h as standard
3632 headers too.
3633 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
3634 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
3635 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
3636 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
3637 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
3638 (C Compiler): Move AC_C_LONG_DOUBLE to ...
3639 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
3640 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
3641 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
3642 (Coding Style). Don't mention m4_expand_once.
3643 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
3644 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
3645 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
3646 (AC_CHECK_FUNCS): Use it.
3647 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
3648 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
3649 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
3650 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.

3681 Revert the patch from 2006-04-01 and only improve
3682 _AS_DETECT_BETTER_SHELL:
3684 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
3685 skip nonexistent directories.
3686 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
3687 only shell candidates which exist.
3688 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
3689 * lib/autotest/general.m4 (AT_INIT): No need to give three
3690 parameters to _AS_PATH_WALK.
3692 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
3693 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3695 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
3696 distinguish m4sugar macros.
3697 * tests/tools.at (autoupdating with aclocal and m4_include):
3698 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
3699 test case by Noah Misch <noah@cs.caltech.edu>.
3701 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3703 Revert my change from 2006-03-17, in other words:
3704 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
3705 and DUALCASE=1.
3706 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
3707 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
3708 it is set.
3710 2006-04-07 Eric Blake <ebb9@byu.net>
3712 * doc/autoconf.texi (Programming in M4sh): Document that
3713 AS_MKDIR_P exits the script on failure.
3714 * lib/autotest/general.m4: Remove redundant AS_ERROR.
3716 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3718 * config/elisp-comp, config/install-sh, config/mdate-sh,
3719 config/missing, config/mkinstalldirs: Sync from Automake.
3721 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
3722 from Automake.
3724 * doc/make-stds.texi: Sync from gnulib.
3726 2006-04-06 Eric Blake <ebb9@byu.net>
3728 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3729 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced

3733 Eric Blake <ebb9@byu.net>,
3734 Paul Eggert <eggert@cs.ucla.edu>,
3735 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3737 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
3738 whether `set' quotes correctly: redirect stderr of the tested
3739 `set', and use a subshell, for Ultrix; use `sed' instead of
3740 `grep' for zsh `set' which may write binary output; match only
3741 at the beginning of a line, to avoid false positives.
3742 In order to avoid false positives by unrelated variables with
3743 multiline content, put the dump algorithm in a subshell and
3744 unset all variables containing newlines (except some which are
3745 special to the shell). Warn about cache variables that are
3746 unset.
3748 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3750 * config/config.guess, config/config.sub, config/texinfo.tex:

3758 (AC_ARG_VAR): Do test this now.
3759 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
3760 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
3761 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
3762 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
3764 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
3765 shell issue with double-quoted command substitutions of native
3766 commands.

3768 Marshall.
3770 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

3787 * tests/Makefile.am (maintainer-check-posix):
3788 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
3790 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
3791 ac_config_<foo>s again, sometimes normalized, sometimes not.
3792 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
3793 (AC_CONFIG_COMMANDS): Do not do so here.
3794 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
3795 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
3796 2005-07-25 rewrite. Noticed by Noah Misch.
3798 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
3799 _AC_PRESERVE_HELP_ORDER, ...
3800 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
3802 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
3803 inside m4_expand_once; it is redundant.
3805 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
3806 for --help from Cygnus `configure.'
3808 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

3818 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
3819 Noah Misch <noah@cs.caltech.edu>
3821 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
3822 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
3823 * doc/autoconf.texi (Help Formatting): New node.
3824 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
3826 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3828 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
3829 lib/autoconf/specific.m4, lib/autoconf/status.m4,
3830 lib/autoconf/types.m4, lib/autotest/general.m4,
3831 tests/mktests.sh, tests/torture.at: White space cleanup:

3834 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
3836 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
3838 2006-04-05 Eric Blake <ebb9@byu.net>
3840 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
3841 empty test suite works.
3842 * tests/autotest.at (Empty test suite): Remove xfail.
3844 2006-04-05 Noah Misch <noah@cs.caltech.edu>

3847 TAGS to ac_config_<foo>s.
3848 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
3849 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
3850 normalizing it, consistent it with previous releases.
3851 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
3853 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3855 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
3856 Use simplified args that Eric Blake originally suggested.
3858 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
3860 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
3861 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
3862 Use 'comm' rather than N instances of grep; this also fixes a bug
3863 whereby substrings were incorrectly matched, causing us to not
3864 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
3865 (exclude_list): Exclude empty macros.
3866 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
3868 Use awk rather than grep -E or egrep, to avoid
3869 portability problems with regular expressions containing newlines.

3871 Switch from grep to awk syntax.
3872 (ac_exclude_script): Renamed from ac_exclude_egrep.
3873 (au_exclude_script): Renamed from au_exclude_egrep.
3875 2006-04-04 Noah Misch <noah@cs.caltech.edu>
3877 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
3878 a subdirectory subject to Cygnus `configure'.
3879 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
3881 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
3882 report request when we have no AC_PACKAGE_BUGREPORT.
3884 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3886 * THANKS: Update.

3889 generated files.
3891 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
3892 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
3893 typedef'ed restricted pointer, to catch a compiler bug on
3894 HP-UX 11.x, and fix warnings so it passes with -Werror.
3895 (_AC_PROG_CC_C99): Likewise.
3896 Reported by Albert Chin <china@thewrittenword.com>.
3897 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.

3912 * THANKS: Add myself.
3914 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3916 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
3917 to log, point to testsuite output tree.
3919 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>

3926 Remove; all uses removed.
3927 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

3947 Clean up _AC_COMPILER_EXEEXT* macros.
3949 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3950 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3951 ac_file to the name of the default output file and call
3952 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3953 initial `rm' of the candidate files...
3954 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3955 the same list in subsequent `rm' calls, and for the temporary
3956 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3957 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3958 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3959 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3960 no longer needed) by libtool. Make it a cache check.
3961 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3962 copied here by mistake.
3963 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3964 _AC_COMPILER_EXEEXT.
3965 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
3966 _AC_COMPILER_OBJEXT directly.

3997 * lib/autoconf/general.m4 (_AC_INIT_VERSION): Emit script name and
3998 Autoconf version number despite a zero- or one-argument AC_INIT.
4000 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
4001 subordinate tools.
4002 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
4003 * doc/autoconf.texi (autoreconf Invocation): Document it.
4005 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
4006 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.

4014 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4016 * bin/autoupdate.in: Redefine m4_location so that warnings print
4017 the correct lines of the input file by subtracting..
4018 (_au__first_line): ..this new definition.
4020 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
4021 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
4022 Remove stray newline in output.
4023 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
4024 AC_DEFUN this for autoconf, including the obsoletion diagnose.
4025 Fixes autoupdating of code where the replacement output contains
4026 m4sugar macros.
4027 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
4028 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

4030 * tests/tools.at: Several new tests for all of this.
4031 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
4032 hairy details.
4033 The AC_LANG_SAVE issue was reported against Libtool by
4034 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
4035 Kristian Kvilekval <kris@cs.ucsb.edu>.
4037 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4039 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
4040 switch all of them on and of when necessary. Fixes the bug when
4041 m4sugar macros (e.g., m4_define) were expanded after the first
4042 automatic update (e.g., after AC_PREREQ or AC_INIT).
4044 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

4066 2006-03-30 Chris Pickett <cpicke@cs.mcgill.ca> (tiny change)
4068 * doc/autoconf.texi (autoreconf Invocation): Mention that -I for
4069 aclocal cannot be given on the command line.
4071 2006-03-29 Paul Eggert <eggert@cs.ucla.edu>
4073 * doc/autoconf.texi (Programming in M4sh): Mention AS_BASENAME.
4074 Give an example for AS_DIRNAME instead of referring to Posix..
4075 (File System Conventions): Put discussion of // versus / here, and
4076 modernize it a bit.
4077 (Limitations of Usual Tools): Add basename. Remove verbiage
4078 after dirname, since it got moved to the above sections.
4079 All this was inspired by a patch proposed earlier by Eric Blake.
4081 2006-03-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4087 `$0', $as_me.
4089 2006-03-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4091 * bin/autoscan.in: The value of find_configure_ac should be
4092 checked for existence, so we don't barf over a nonexisting
4093 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
4095 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4681 Factor functionality to..
4682 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
4683 `AC_SUBST($1)' in the public version.
4684 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
4685 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
4686 ac_pt_* variables.

4710 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
4711 conftest.o, to see whether the compiler really obeys; rm the object
4712 file before and after the test and register it with ac_clean_files.
4713 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
4715 2005-10-21 Stepan Kasal <kasal@ucw.cz>

4738 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
4739 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
4740 by the function rather than ignoring it.
4741 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
4742 comparing its address. Intel's interprocedural optimization was
4743 outsmarting the old heuristic. Problem reported by
4744 Mikulas Patocka.
4746 2005-10-19 Stepan Kasal <kasal@ucw.cz>
4748 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

4755 2005-10-04 Stepan Kasal <kasal@ucw.cz>
4757 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
4758 before removing it (chmod -R u+rwx); there are three instances of this.
4760 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4761 Stepan Kasal <kasal@ucw.cz>
4763 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
4764 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
4765 make its content writable before removing it. Remove an errorneous
4766 comment from the end, where the logs of the failed tests are copied
4767 to the main log file.
4769 2005-09-27 Stepan Kasal <kasal@ucw.cz>
4771 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
4772 in case the computer is too quick. Double quote the configure.ac
4773 snippets.
4775 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
4776 problems if the testsuite were running too fast.
4778 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4780 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4781 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4782 (which belong to Xt, not X itself). See Debian bug 327655.
4783 * NEWS: Mention this.
4785 2005-09-07 Stepan Kasal <kasal@ucw.cz>
4787 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
4789 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
4791 * config/move-if-change: Don't output "$2 is unchanged";
4792 suggested by Ben Elliston. Handle weird characters correctly.
4794 2005-09-06 Stepan Kasal <kasal@ucw.cz>
4796 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
4797 calls, so that the final expansion of this macro is shorter.
4798 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
4799 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
4800 the cleanup there. Use AS_VAR_* macros, to be more general.
4801 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
4803 * lib/autoconf/general.m4: Use AS_IF where appropriate.
4805 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
4807 2005-09-01 Stepan Kasal <kasal@ucw.cz>
4809 * doc/autoconf.texi (Configuration Headers): Add an index entry
4810 for AH_HEADER.
4812 2005-08-26 Pavel Roskin <proski@gnu.org>
4814 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
4815 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
4816 running xmkmf.
4818 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
4820 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4821 The previous patch didn't work, so try a better one.
4823 2005-08-26 Stepan Kasal <kasal@ucw.cz>
4825 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
4826 in the example. Reported by Bruno Haible.
4827 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
4828 "if $undefined_var;" succeeds with my shell.
4830 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
4831 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
4832 but change the m4_divert_text to m4_divert_once.
4834 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
4836 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4837 Work around bug in Solaris /usr/xpg4/bin/awk.
4838 The bug is present in at least Solaris 8 through 10.
4840 2005-08-24 Stepan Kasal <kasal@ucw.cz>
4842 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
4843 some evil values and relying on the fact that $* concatenates the
4844 parameters by the first character from IFS.
4846 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4847 Stepan Kasal <kasal@ucw.cz>
4849 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
4850 first header appears, define AH_HEADER.
4851 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
4852 Update limitations about when to call AC_CONFIG_HEADERS.
4853 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4854 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4855 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4856 ``Configuration Actions''; fix their index entries.
4858 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4859 options correctly. Process N-M as M-N if M is smaller than N.
4860 Process ranges correctly so that N-N will run only N.
4861 Sort and uniquify the tests that will be run. If there is more
4862 than one test, reinsert the banners for the tests.
4863 * tests/autotest.at (Keywords): Unmark XFAIL.
4865 2005-08-23 Stepan Kasal <kasal@ucw.cz>
4867 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
4868 before passing the macro name to AH_TEMPLATE.
4870 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
4871 now opens log after option processing; in particular, --version
4872 and --help do not touch config.log.
4874 * Makefile.maint: Revert the change from 2005-08-12.
4876 2005-08-22 Stepan Kasal <kasal@ucw.cz>
4878 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
4879 common code to...
4880 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
4882 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4884 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
4885 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
4886 Language cleanup.
4888 * doc/autoconf.texi (Defining Symbols, Changed Results):
4889 Prepend to LIBS, not append, in examples.
4891 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4893 When building in place, set srcdir="."; suggested by Tim Van Holder.
4895 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4896 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4897 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4898 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
4899 does not mean "no --srcdir option".
4901 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4903 * tests/autoscan.at (autoscan): New file.
4904 * tests/suite.at: Use it.
4905 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
4906 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
4908 * tests/autotest.at (Keywords): Test keywords combinations.
4910 2005-08-12 Stepan Kasal <kasal@ucw.cz>
4912 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
4913 add "2>&1"; gzip 1.2.4 prints help on stderr.
4915 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4917 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
4918 was pushdef'ed twice while popped only once. Push it only once.
4919 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
4921 2005-07-26 Stepan Kasal <kasal@ucw.cz>
4923 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
4924 prefixed by mere "===", not "configure: === ".
4926 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
4928 * Makefile.maint: Update from Bison.
4930 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
4931 "<tab>" in comment, so that the point is understandable.
4933 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4935 Rewrite substantial part of lib/autoconf/status.m4.
4936 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4937 and CONFIG_COMMANDS are not processed in four separate loops.
4938 Instead, there is one main loop. This alows that the common code
4939 is expanded only once, thus config.status (and configure) is smaller.
4941 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4942 the AC_LIST_FILES and cousins macros are no longer used.
4944 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4945 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4946 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4947 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4948 contain the initialization, nor the for loop, nor the associated
4949 commands; all these go to ...
4950 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4951 _AC_OUTPUT_CONFIG_STATUS.
4952 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4953 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4954 (_AC_OUTPUT_FILE): The creation of the sed script ...
4955 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4956 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4957 _AC_OUTPUT_MAIN_LOOP.
4958 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4959 _AC_CONFIG_COMMANDS): Use ...
4960 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4961 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4962 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4963 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4964 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4965 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4966 ... new macros.
4967 (_AC_CONFIG_UNIQUE): Update.
4968 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4969 Replaced by this ...
4970 (_AC_LIST_TAGS): ... new common macro.
4971 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4972 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4973 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4974 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4975 this didn't belong to the `config commands' section.
4976 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4977 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4978 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4979 to the `config commands' section either.
4980 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4981 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4983 ... and many changes to the comments nearby.
4985 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4986 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4987 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4988 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4989 (#define header templates): The comment at the top of the generated
4990 header now includes the name(s) of the source file(s).
4992 Several unrelated small changes:
4994 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4995 parameter to AC_DIAGNOSE.
4996 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4997 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4998 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4999 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
5000 with AU::AC_OUTPUT.
5001 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
5002 in AC_OUTPUT doesn't double-quote it either.
5003 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
5004 parameters.
5006 2005-07-10 Stepan Kasal <kasal@ucw.cz>
5008 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
5009 versions of Portland Group compiler produce single- and double-quoted
5010 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
5011 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
5013 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
5015 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
5016 This is a corrected version of yesterday's patch.

5025 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
5027 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
5028 change eliminates it. Problem reported by Alexandre Duret-Lutz.
5029 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
5030 (AC_ARG_VAR): ... here.
5031 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
5032 target_alias.
5034 Keep a list of all precious variables and process them with one simple
5035 for loop, instead of expanding all commands, or, OTOH, complicated
5036 processing of output of "set".
5037 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
5038 variable names in new macro...

5041 a loop to assign all ac_env_* and ac_cv_env_* variables.
5042 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
5043 to INIT_PREPARE.
5044 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
5045 its value to shell variable ac_precious_vars and call
5046 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.

5071 2005-07-05 Stepan Kasal <kasal@ucw.cz>
5073 Fix my changes from 2005-07-01; reported by Noah Misch.

5088 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

5093 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
5094 sed substitution command, so that we allow | in program prefixes
5095 and program suffixes. (& is a problem anyway; we're not fixing
5096 that here.)
5097 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
5098 configure_input, top_builddir, srcdir, etc.
5099 * lib/autotest/general.m4 (AT_INIT): Likewise, for
5100 PATH_SEPARATOR in AUTOTEST_PATH.
5102 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
5104 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the

5110 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
5111 directories with weird names. Apparently some people like living

5135 Likewise for --header; moreover, recognize --he and --h as shortcuts
5136 for --help in that case.
5138 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
5139 matches the order of execution. No code changed.

5161 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
5162 (AC_SUBST): Call it.
5163 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
5164 the directory specific variables; but don't call it for configure_input.
5166 2005-06-28 Derek Price <derek@ximbiot.com>
5168 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
5169 addition.
5171 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
5173 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
5174 directory have inherent problems with special characters like spaces,
5175 due to limitations in Make syntax. Problem reported by Alexandre
5176 Duret-Lutz.
5177 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

5190 from Justace Clutter.
5191 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
5192 variable into diagnostic. Make the diagnostic an error, not a warning,
5193 because we really don't support spaces and suchlike in dir names.
5194 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
5195 Don't worry about backslashes in srcdir; it can't happen now.

5209 that '\|' is not allowed in BREs; recommend using newline separated
5210 list of patterns instead of multiple -e options.
5212 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
5214 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

5222 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
5223 b, t, r, w commands require single space, while : cannot have any.
5224 (Special Shell Variables): Fix sed code this in the example.
5225 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
5226 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
5228 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
5229 expand to the empty list. Don't use two pairs of m4_changequote,
5230 it's not necessary.
5232 2005-06-20 Derek Price <derek@ximbiot.com>
5234 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.

5238 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
5239 * doc/autoconf.texi:
5240 Don't mention Solaris versions so much, if a
5241 problem is common to all extant versions of Solaris. Say "SunOS
5242 4" instead of "SunOS" for SunOS 4.
5243 (awk): Mention more of the limitations of traditional Awk.
5244 (cat): Don't talk about cat -v.
5246 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

5251 to be compatible with glibc strverscmp.
5252 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
5254 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
5255 on Mac OS X 10.4 reported by Peter O'Gorman in:

5257 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
5258 Use shell builtins rather than 'expr', to work around expr bug.
5260 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
5262 * doc/autoconf.texi: "filesystem" -> "file system".
5263 "behaviour" -> "behavior".

5282 AS_TR_SH.
5284 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
5286 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
5287 -u, since it outputs chatter if the input files are the same.
5288 Problem reported by Ralf Menzel.
5290 2005-06-08 Derek Price <derek@ximbiot.com>
5292 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
5293 renaming them since they are about to be redefined anyhow.
5295 2005-06-08 Derek Price <derek@ximbiot.com>
5297 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
5298 redefined M4 macros to this node. Document m4_include & m4_sinclude.
5299 Move m4_undefine to alphabetical order.
5301 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
5303 * README: Recommend GNU M4 1.4.3 or later.
5304 * doc/autoconf.texi (Introduction): Likewise.
5305 Reword to avoid some formatting glitches.
5306 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
5307 Clarify explanation of HP compiler bug.
5308 Redo example output tp match current CVS snapshot.
5309 Use @example.org in email addresses when the examples
5310 might get inadvertently cut-and-pasted into user code.
5311 Remove example of autom4te usage that doesn't seem to work now.
5312 Use modern AC_INIT (except when the example is meant to be
5313 shown with Autoconf 2.13).
5314 Update ksh info for Solaris 9 and later.
5315 KB -> kB.
5316 Modernize description of Automake versions a bit.
5317 Don't claim a future version of Autoconf is near.

5324 Reword to avoid some formatting glitches.
5325 * doc/installt.exi: Reword to avoid some formatting glitches.
5327 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
5328 Tru64 ksh pattern matching bug. Reported against Libtool by
5329 Albert Chin <libtool@mlists.thewrittenword.com> and
5330 Nicolas Joly <njoly@pasteur.fr>.
5332 2005-06-06 Stepan Kasal <kasal@ucw.cz>
5334 m4_cdr of one-member list was [[]] (one-member list containing an
5335 empty string) instead of [] (an empty list. Callers were skewed to
5336 match this misbehaviour. As a consequence of this:
5337 - m4_foreach([x], [], [foo]) expanded to `foo', while
5338 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
5339 This bug has been fixed:
5341 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
5342 expand to an empty string; print error msg if called without
5343 an argument list.
5344 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
5345 misbehaviour; handle [] and [[]] correctly.

5353 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
5355 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
5356 swallow records with more than 99 fields.
5357 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
5358 parse the long line.
5360 2005-06-04 Stepan Kasal <kasal@ucw.cz>
5362 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
5363 swallow literals longer than 399. Reported by Ralf Wildenhues.

5367 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
5369 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
5370 to gfortran, and make these the first two compiler names
5371 checked (following the general autoconf preference for gcc).
5373 2005-06-03 Stepan Kasal <kasal@ucw.cz>
5375 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
5376 (DISTCLEANFILES): Remove $(check_SCRIPTS).
5377 (testsuite): Make sure autotest.m4f is up-to-date before using it.

5381 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
5382 expression of unbounded size when processing the --list
5383 option. This runs afoul of a limit of 399 bytes per regular
5384 expression on AIX. Problem reported by Ralf Wildenhues.

5393 Reword description of line replacement.
5395 2005-05-31 Dan Manthey <dan_manthey@partech.com>
5397 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
5398 now contain newlines, and substituted files must be referenced on
5399 a line alone; the sed scripts to substitute them are now very
5400 different.
5401 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
5402 commands can be put in a sed script portably.
5403 * doc/autoconf.texi (Setting Output Variables): Document above

5415 * tests/local.at: Don't attempt to check for negated character
5416 classes in shell scripts. The test was too brittle.
5418 2005-05-25 Stepan Kasal <kasal@ucw.cz>
5420 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
5421 * doc/autoconf.texi (Limitations of Builtins): Document this
5422 limitation.
5424 2005-05-24 Stepan Kasal <kasal@ucw.cz>

5434 messages when ac_unique_file is not found.
5435 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
5436 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo

5452 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
5453 (ac_top_builddir): ... this ...
5454 (ac_top_build_prefix): ... to this; the old name is also kept, for
5455 backward compatibility.
5456 (ac_top_builddir_sub): New variable, without the trailing slash,
5457 always nonempty.
5458 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

5472 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
5473 argument to m4_foreach. I guess it was necessary in the past,
5474 but I think it's a no-op now.
5476 2005-05-17 Stepan Kasal <kasal@ucw.cz>
5478 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
5479 ``cat <<_ACEOF'' commands to one.
5480 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
5481 * lib/autoconf/status.m4: On various places, use expr instead of
5482 ``echo|sed.''
5483 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
5484 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
5485 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
5486 a range.
5487 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
5488 the wrong patterns between ``case'' and ``esac.'' The previous
5489 code had false positives.
5491 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
5493 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
5494 as on 2005-05-02.
5495 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
5496 Mention LIBOBJDIR.

5539 check.
5540 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
5541 enough arguments, similarly as in m4_bpatsubsts.
5543 2005-05-12 Stepan Kasal <kasal@ucw.cz>
5545 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation

5548 2005-05-11 Stepan Kasal <kasal@ucw.cz>
5550 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
5551 for absolute directory names in one loop.
5552 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
5553 abbreviations of --version and --debug.
5555 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
5557 * doc/autoconf.texi (Autoconf Language): Be more precise about
5558 quoting rules. Problems noted by Stepan Kasal.
5559 Also, throughout this document, be more careful about white space.
5560 "blank", "white space", and "space" all have different meanings
5561 and we should be careful to say what we mean.
5563 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
5565 Fix C++ related problems reported by Werner Lemberg.
5566 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
5567 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
5568 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
5569 avoid problems with C++ and throw.
5570 * tests/compile.at: .cpp, not .cc.
5572 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
5574 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5576 * doc/autoconf.texi (Generic Functions): Typos.
5578 2005-05-02 Gary V. Vaughan <gary@gnu.org>
5580 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
5581 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
5582 set by latest automake.
5584 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
5586 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
5587 outputs 0 on GNU/Linux these days.
5589 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
5591 * doc/autoconf.texi (Autoconf Language): Add more description
5592 about quoting heuristics.
5593 (Limitations of Builtins): Describe "set -" problems.
5595 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5597 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
5598 not newline.
5600 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
5601 by AC_DEFINE; it was a mistake.
5602 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
5604 2005-04-25 Stepan Kasal <kasal@ucw.cz>
5606 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
5608 2005-04-22 Stepan Kasal <kasal@ucw.cz>
5610 * doc/autoconf.texi (External Software): Quadrigraphs are not
5611 processed correctly in AS_HELP_STRING; avoid this in the examples.
5612 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
5613 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
5614 comment and reduce m4_default([foo], []) to [foo].
5615 (m4_strip): Update the explanation.
5617 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
5619 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
5620 Remove core.conftest.* too; it's generated by Tru64 5.1.
5621 Problem reported by Jennis Pruett.
5622 * lib/autoconf/functions.m4
5623 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
5624 Don't bother to remove core files; AC_RUN_IFELSE should do that
5625 for you.
5627 2005-04-19 Stepan Kasal <kasal@ucw.cz>
5629 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
5631 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>

5636 2005-04-15 Stepan Kasal <kasal@ucw.cz>
5638 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
5639 the comment.
5641 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
5643 * doc/autoconf.texi (External Software, Package Options): Add
5644 examples showing how to implement --with-* and --enable-* options.
5646 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
5648 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
5649 as well as configure.in. Problem reported by Gregorio Guidi.
5651 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
5653 * doc/autoconf.texi (Particular Functions): Use gnulib's current
5654 pattern for alloca snippet.
5656 2005-04-04 Stepan Kasal <kasal@ucw.cz>
5658 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
5660 2005-04-01 Stepan Kasal <kasal@ucw.cz>
5662 * doc/autoconf.texi (Generic Programs): Fix a typo.
5664 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
5666 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
5667 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
5669 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5671 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
5672 Merge `-z option' as well for the benefit of Solaris link flags. Pass
5673 whole-archive (-zallextract, -zdefaultextract) options in the hope of
5674 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
5675 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
5677 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
5679 * NEWS: The configure command now warns you if you attempt to use
5680 a directory whose name contains a special character like space,
5681 newline, or "\".
5682 * doc/autoconf.texi (Installation Directory Variables): Allow
5683 "," in file names. Do not use \@; it's not a portable regexp.
5684 * bin/Makefile.am (edit): Likewise.
5685 * lib/Makefile.am (edit): Likewise.
5686 * tests/Makefile.am (edit): Likewise.
5687 * tests/semantics.at: Likewise.
5688 * tests/torture.at: Likewise.
5689 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
5690 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
5691 * doc/autoconf.texi (File System Conventions): Warn about
5692 unportable file names.
5693 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
5694 (AC_INIT): Use it.
5695 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
5696 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
5697 ac_pwd, and quote srcdir.
5698 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
5700 * doc/autoconf.texi: Fix some systematic formatting problems.
5701 ".)" needs a following @: if not at the end of a sentence, and
5702 similarly for "!)". "etc." should be preceded by a comma.
5703 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
5705 2005-03-22 Bruno Haible <bruno@clisp.org>
5707 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
5708 argument is often called 'build-aux'.
5710 2005-03-07 Stepan Kasal <kasal@ucw.cz>
5712 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
5713 macro AC_TRY_LINK is obsolete.
5714 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
5715 `AC_CONFIG_FILES'.
5717 2005-02-24 Stepan Kasal <kasal@ucw.cz>
5719 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
5720 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
5721 from a Common Lisp's `cl'.
5722 (AC_PROG_CXX): Behave according to the documentation: don't
5723 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
5724 make the variable CCC precious; use `cl.exe', not `cl'.
5726 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5727 Alexandre Duret-Lutz <adl@gnu.org>
5729 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
5730 /dev/null, as "configure" shouldn't read stdin, and this insulates
5731 us from problems (e.g., when testing for "cl"). Also, do this
5732 redirection before invoking "hostname" or "uname", and keep the
5733 original input stream available via...
5734 (AS_ORIGINAL_STDIN_FD): ... this new macro.
5735 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
5736 bother with "</dev/null" since it's now done at the top of
5737 'configure'.
5738 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
5739 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5740 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5741 * doc/autoconf.texi (File Descriptor Macros): New section.
5742 (Printing Messages): Mention it.
5743 * tests/base.at (Input/Output): New test.
5745 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5747 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
5748 newline if neither \c nor -n work, as that would output two
5749 newlines. Prefer -n to \c. Reported by Stepan Kasal.
5751 2005-02-12 Stepan Kasal <kasal@ucw.cz>
5753 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
5754 This causes that any required macros inside will get before the if.
5755 * doc/autoconf.texi (autom4te.cache): A typo.
5757 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
5759 Undo previous change, except keep the change to
5760 lib/autoconf/programs.m4 that replaced grep with shell
5761 pattern-matching. This is because net-snmp configure reads stdin.
5762 Reported by Noah Misch.
5764 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
5766 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
5767 from /dev/null, as "configure" shouldn't read stdin, and this
5768 insulates us from problems (e.g., when testing for "cl").
5769 Suggested by Alexandre Duret-Lutz. Also, do this redirection
5770 before invoking "hostname" or "uname".
5771 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5772 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
5773 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
5774 "</dev/null" since it's now done at the top of 'configure'.
5775 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5776 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5777 Also, replace grep with shell pattern-matching, to save a process.
5779 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
5781 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5782 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
5783 avoid thinking that Allegro Common Lisp's "cl" command is a C++
5784 compiler.
5786 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
5788 * doc/autoconf.texi (Limitations of Usual Tools): Document that
5789 grep -q isn't portable. Improve grep -s explanation.
5790 Problem reported by Dan Manthey.
5792 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
5794 * doc/autoconf.texi (Special Shell Variables): Clarify
5795 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
5797 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
5799 * doc/autoconf.texi: Use @acronym for DJGPP.
5800 Fix some @code's that should have been @env's, and vice versa.
5801 Sort environment variable names.
5802 Mention that shells no longer inherit IFS.
5803 Don't recommend PATH_SEPARATOR=';' so strongly.
5804 Mention that $RANDOM might expand to the empty string.
5805 "symlink" and "soft link" -> "symbolic link".
5806 Improve mktemp description (reported by Bruno Haible).
5808 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
5810 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
5811 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
5812 Likewise.
5813 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
5814 Likewise.
5816 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
5818 * NEWS: Mention AT_COPYRIGHT.
5820 * tests/local.at (AT_CMP): Use diff directly on input files rather
5821 than copying them.
5823 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
5824 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
5826 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5827 and Paul Eggert <eggert@cs.ucla.edu>
5829 * tests/autotest.at (Empty test suite): New test.
5830 * tests/torture.at (Substitute and define special characters)
5831 (Substitute a 2000-byte string, Define to a 2000-byte string)
5832 (Substitute a newline, Define a newline): New tests.
5834 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5836 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
5837 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
5838 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
5839 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
5840 (Standard regular expressions): New test.
5841 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
5842 excess test name quoting.
5843 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
5844 CPPFLAGS to `configure' instead of setting it in `configure'.
5846 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
5847 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
5848 on some platforms.
5850 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
5851 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
5853 * tests/local.at (AT_CMP): New macro.
5854 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
5855 (AC_SAVE_STATE): Move environment grep...
5856 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
5857 (AT_CONFIG_CMP): New macro.
5858 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
5859 * tests/c.at (Extensions): Do not exit early.
5860 * tests/atlocal.in: Inherit $GREP.
5862 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
5863 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
5865 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
5866 (AC_COPYRIGHT): Factor header comment portion out and move into...
5867 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
5868 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
5869 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
5870 --version output.
5871 * tests/local.at: Add Autoconf test suite copyright notice.
5872 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
5874 2005-02-04 Bruno Haible <bruno@clisp.org>
5875 and Paul Eggert <eggert@cs.ucla.edu>
5877 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
5879 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
5881 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
5882 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
5884 Try not to generated lines of unlimited length, as POSIX places a
5885 2047-byte limit on line length of portable text files.
5886 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
5887 Use newline as a separator, not space.
5888 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
5889 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
5890 space.
5892 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5894 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
5895 as_func_*. Add test to check whether positional parameters
5896 are restored after function return.
5898 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
5900 * doc/autoconf.texi (Special Shell Variables): Mention _,
5901 BIN_SH, DUALCASE. Say that variables other than "status" are safe
5902 if they contain a lower-case letter. The DUALCASE problem was
5903 reported by Ralf Wildenhues.
5905 * bin/autoconf.as: Don't exit with status 0 after write failure
5906 with --help or --version.
5907 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

5945 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5946 Update the long comment explaining it.
5948 m4_require no longer writes an ``is required by'' line to the
5949 execution stack. It contains only one bit of non-redundant
5950 information: that the macro was required, not called. And even
5951 this bit is useless in most situations: have you ever met a macro
5952 which both calls and requires the same macro?
5954 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5955 (_m4_defun_pro_outer): ... only via this macro, for the outermost

5963 * tests/m4sugar.at (m4_require): Expect output without the
5964 ``is required by'' messages.
5966 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
5968 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
5969 rather than x for expr.
5971 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
5972 this is safe.
5973 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.

5987 support.
5988 * bin/autoheader.in: Pass $force to update_file so that
5989 config.h.in is always recreated when --force.

5993 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
5995 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
5997 * doc/autoconf.texi (Limitations of Builtins): Clarify that

6000 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
6002 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
6003 Warn about newline stripping in `` and $(). Update Solaris
6004 version to 9.

6006 X insulates us from future changes to Posix.
6007 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
6008 stripping.
6010 2005-01-19 Stepan Kasal <kasal@ucw.cz>

6030 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
6032 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
6034 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

6056 (_m4_divert_n_stack): New macro; the expansion is
6057 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
6058 otherwise.
6059 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
6060 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
6061 stored in _m4_divert_diversion or _m4_divert_dump.
6062 (m4_divert_pop): When the parameter is given, compare the symbolic
6063 name with the last diversion pushed on the stack. Previously, the
6064 current diversion was compared with the numeric value of the
6065 diversion given as the parameter.
6066 (m4_require): If the macro hasn't been expanded yet, call ...
6067 (_m4_require_call): this new macro.

6100 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

6102 not essential. Reported by Magnus Therning.
6103 * tests/torture.at (autoreconf.): New banner.
6104 (autoreconf and non-AC configure): Rename to `Non-Autoconf

6153 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
6154 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

6281 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

6368 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
6369 value of the #define--default to 1, iff the macro was called
6370 with exactly one parameter.
6372 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
6374 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
6375 "char c = '\200';" rather than "char c = 0x80;" as the
6376 latter doesn't conform to the strict C standard due to
6377 overflow on signed char hosts.
6379 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
6380 to -qlanglvl=ansi. We don't want to disable extensions.
6382 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
6384 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
6385 (Using Autotest, testsuite Scripts, Writing testsuite.at):
6386 Reword slightly to avoid some English-language problems noted

6436 simplify the examples and improve their quoting.
6438 2004-11-13 Stepan Kasal <kasal@ucw.cz>
6440 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
6441 the $1_found variable, don't test whether the file is executable;
6442 Both things are checked ...
6443 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
6444 the former ``test -f''.
6445 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
6447 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

6450 use cp -R instead.
6452 2004-11-10 Derek R. Price <derek@ximbiot.com>
6454 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
6455 limitations. Reorder paragraphs for clarity.
6457 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
6459 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
6460 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
6461 variants", "Unix", and some related minor wording fixups.
6463 (Shellology, Special Shell Variables): Document that the Zsh
6464 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks

6476 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
6478 * doc/autoconf.texi (auindex): New macro.
6479 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
6480 Problem reported by Stepan Kasal.
6482 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
6484 Fix problems reported by Andreas Buening in:
6485 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
6486 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
6487 in test makefile.
6488 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
6489 readable; it's not true in OS/2-emx.
6491 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
6493 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
6494 "/usr/include", clear ac_x_includes instead of leaving it as "no"
6495 (trivial change). Problem and patch reported by Andrew Church in:
6496 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
6498 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

6503 Also, fix some minor spacing and punctuation bugs.
6505 2004-09-02 Akim Demaille <akim@epita.fr>
6507 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and

6521 Version 2.59b.
6523 * README: Add advice about m4 1.4.2.
6525 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
6526 texinfo.tex for now (done by hand now).
6527 * Makefile.maint (wget_files, cvs_files):
6528 Remove ansi2knr.c; nobody uses it.
6529 (ansi2knr.c-url_prefix): Remove.
6530 (cvs-update): Fix test for failure. I don't know why it ever
6531 worked...
6533 * doc/autoconf.texi: Update URLs, some of which went stale.
6534 Use @uref rather than @href.
6536 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
6537 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
6539 * config/config.guess, config/config.sub, config/elisp-comp,
6540 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
6541 doc/fdl.texi, doc/standards.texi: Sync with master copy.
6543 * NEWS, TODO, configure.ac, bin/autoscan.in,
6544 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
6545 doc/install.texi, lib/Autom4te/Configure_ac.pm,

6549 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
6550 tests/tools.at, tests/torture.at:
6551 Use "file name" rather than "filename" or "path",
6552 to be consistent with the terminology of the GNU coding standards.
6554 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
6556 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
6557 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
6558 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
6559 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
6561 More fixes to support spaces in the name of the build directory.
6562 This isn't a complete fix but it's an improvement.
6564 * bin/autoconf.as (autom4te_options): New var.
6565 Use it instead of appending to AUTOM4TE, so that we can allow
6566 spaces in the build directory's absolute name.
6567 * bin/autoheader.in ($autoconf): Allow spaces in file names.
6568 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
6569 AT_CHECK_NOESCAPE): Likewise.
6570 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
6571 main program): Likewise.
6573 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
6575 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
6576 From Ralf Corsepius in:

6579 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
6581 * doc/autoconf.texi (Function Portability): Document isinf and
6582 and isnan. From a suggestion by Kevin Ryde.
6584 * lib/Autom4te/General.pm (END): Return correct exit status even
6585 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
6587 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
6589 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
6590 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
6591 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
6593 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
6595 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
6596 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
6597 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
6598 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
6599 * lib/autom4te.in (Automake-preselections): Preselect
6600 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
6602 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
6604 * lib/autom4te.in (Automake-preselections): Preselect
6605 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
6606 trace them.
6608 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
6610 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
6611 Tru64.
6612 * doc/autoconf.texi (Shellology): Mention BIN_SH.
6613 Document problem with "`""`" in pdksh POSIX mode.
6615 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
6617 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
6618 with pdksh, too. Problem reported by Patrick Welche via
6619 Gary V. Vaughan.
6620 * doc/autoconf.texi (Shellology): Note that set -o posix is
6621 useful for pkdsh, too.
6623 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
6625 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
6626 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
6627 Don't fail if ENV or BASH_ENV is readonly.
6628 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
6629 etc. are read only. Problem reported by Ludovic Courtes.
6631 2004-06-23 Noah Misch <noah@cs.caltech.edu>
6633 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
6634 zsh, disable GLOB_SUBST to avoid backslash handling problems.
6635 (trivial change)
6637 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
6639 * doc/autoconf.texi (File System Conventions): Warn about
6640 names like "aux". Problem reported by Eric Blake.
6642 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
6643 by zero instead of array size, so that we can use any arithmetic
6644 constant expression (instead of requiring an integer constant
6645 expression). This allows us to test expressions like DBL_MAX <
6646 LDBL_MAX, which didn't conform to the C standard using the old
6647 method.
6648 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
6649 now that we can do floating-point tests at compile time.
6651 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
6653 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
6654 and LDBL_EPSILON, as the resulting expression isn't an
6655 integer constant expression and violates the C standard.
6656 Problem reported by Nelson H. F. Beebe. Also, check
6657 for "L" suffix, and check that long double doesn't have
6658 worse range or precision than double, that mixed-mode
6659 arithmetic doesn't generate a diagnostic, that double
6660 constants fit in long double.
6662 2004-06-03 Kevin Ryde <user42@zip.com.au>
6664 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
6665 malloc(0) and realloc(NULL,size).
6667 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
6668 Bob Proulx.
6670 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
6672 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
6673 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
6674 by Jim Meyering.
6676 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
6678 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
6679 can be rewritten using if-then-else. Suggested by Bruno Haible.
6681 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
6683 * doc/autoconf.texi (testsuite Scripts): Fix typo.
6684 Problem reported by Stepan Kasal.
6686 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
6688 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
6689 change). Patch reported by Ralf Wildenhues in
6690 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
6692 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
6693 function F exists if the compiler and linker let you compile an
6694 expression like (F != 0). Recent versions of GCC optimize away
6695 the reference to F in that case, since every function address must
6696 be nonzero, so the link succeeds even if F does not exist.
6697 Problem reported by Manu in
6698 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
6700 * doc/autoconf.texi (Systemology): Standardize on the spelling of
6701 "Unix". Many uses changed.
6702 (Limitations of Builtins): Explain better why the ! command isn't
6703 portable.
6705 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
6707 * lib/autom4te.in (Automake-preselections): Preselect
6708 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
6710 2004-05-19 Kevin Ryde <user42@zip.com.au>
6712 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
6713 referencing AC_FUNC_STRERROR_R.
6715 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
6716 note pessimistic assumption when cross compiling.
6718 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
6720 * doc/autoconf.texi (Limitations of Make): Note that BSD make
6721 (until 2004) invoked subcommands with sh -e, contra POSIX.
6722 Reported by Kevin Ryde.
6724 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
6726 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
6727 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
6728 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
6729 `test -f " /usr/bin/grep"', which _always_ failed.
6730 (AC_PROG_SED): Ditto bogus PATH fix.
6731 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
6732 requires that grep correctly supports _multiple_ `-e' options, rather
6733 than stating only that grep should accept `-e'.
6735 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
6737 Port to C99, which requires that 'exit' be declared.
6739 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
6740 to ensure that stdlib.h is included.
6741 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
6742 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
6743 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
6744 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
6745 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
6746 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
6747 when using 'exit' in a test; C99 requires that 'exit' be declared.
6749 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
6751 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
6752 now prefers 'grep' implementations that accept -e.
6753 (Limitations of Usual Tools): Describe problems of traditional
6754 egrep and fgrep with long input lines, and of traditional grep
6755 with -e.
6756 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
6757 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
6758 All callers changed. Append /usr/xpg4/bin to the PATH, for
6759 Solaris.
6760 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
6761 the user with complaints about multiple -e options.
6762 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
6763 Define it with AC_PROG_GREP.
6764 * configure.ac (AC_PROG_GREP): Add.
6765 * lib/freeze.mk (GREP): New macro.
6767 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
6769 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
6770 a possible candidate only after all others fail, rather than
6771 consulting it first. This improves backward compatibility by
6772 better reflecting the way shell selection occurred in previous
6773 versions of Autoconf, and should help to avoid triggering latent
6774 problems in other packages, such as the one in Automake where zsh
6775 is not handled robustly:
6776 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
6777 Although it is not Autoconf's responsibility to work around
6778 problems in Automake, it nevertheless makes sense to avoid
6779 introducing unnecessary incompatibilites.
6781 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
6782 Gary V. Vaughan <gary@gnu.org>
6784 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
6785 how deeply nested we are when a suitable tool is found, set the
6786 ac_path_TOOL_found flag.
6787 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
6788 nested we are in this macro. Break out of all 3 nested loops if
6789 ac_path_TOOL_found is set.
6791 2004-04-21 Gary V. Vaughan <gary@gnu.org>
6793 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
6794 of the _AS_PATH_WALK loop too if GNU flavor is found.
6796 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
6798 * doc/autoconf.texi (Limitations of Make): Update documentation
6799 for `$<'. New entry `Long lines', based on a report from Simon
6800 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
6801 paragraph about DJGPP, based on a mail from Richard Dawe.
6803 2004-04-20 Paul Eggert <eggert@twinsun.com>
6805 * tests/c.at (C keywords): Don't assume that GCC supports
6806 "restrict" and "inline", as sufficiently-old GCC versions do not
6807 (also, GCC configured to be in pedantic C89 mode does not).
6808 Problem reported by Sumit Pandya in:
6809 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
6811 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
6812 consider -g to work if it generates warnings when plain compiles
6813 don't. Problem reported by Braden McDaniel in:
6814 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
6816 * doc/autoconf.texi (Slashes): New section, to document a problem

6827 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
6828 best tool so far counter rely on the tool path variable name to
6829 avoid checks for one tool being affected by the results of running
6830 the length check on a previous tool.
6832 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
6833 match expression argument, as different greps have different
6834 regular expression flavours.
6835 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
6836 literals.
6837 (AC_PROG_EGREP): Pass 'EGREP$'.
6838 (AC_PROG_GREP): Pass 'GREP$'.
6840 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>

6847 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
6848 Types, Specific Compiler Characteristics, System Services,
6849 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
6850 etc. consistently instead of 'long', 'short', 'unsigned' etc.
6851 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
6852 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

6865 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
6866 now defines HAVE_DECL_TZNAME if it is declared, when
6867 HAVE_STRUCT_TM_TM_ZONE is not defined.
6868 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
6869 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
6870 for HAVE_TZNAME.

6882 H. F. Beebe for the bug report.
6884 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
6886 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
6887 quoted -cmdline argument in Portland Group compiler (bug
6888 reported by Jeffrey J. Barteet).

6918 new macros.
6919 * NEWS: Document these changes.
6921 * doc/autoconf.texi: Avoid macros with unbraced arguments,
6922 they make TeX hang up.

6927 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
6928 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
6929 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
6930 vowel.

6950 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6952 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'

6955 2004-02-18 Paul Eggert <eggert@twinsun.com>
6957 Fix a dependencies problem, stemming from a Autoconf 2.59 build
6958 problem on QNX reported by Stephen Rasku in
6959 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
6961 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
6962 $(m4sh_m4f_dependencies); this removes a FIXME.
6963 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
6964 (MAINTAINERCLEANFILES): Split into pieces,
6965 one per related section. Add $(srcdir)/wrapper.in.
6967 2004-02-09 Paul Eggert <eggert@twinsun.com>
6969 * doc/autoconf.texi (Setting Output Variables): Emphasize that
6970 AC_SUBST provides no portable way to escape literal newlines.
6972 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6973 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6974 Darwin uses -lcrt2.o and there's little point to cataloging all
6975 the system variants. Partial fix reported by Andreas Waechter in:
6976 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

7007 (_AS_SHELL_FN_SPY): New macro.
7008 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New

7016 it is used.
7017 (_AS_LINENO_WORKS): Put around braces, we do not
7018 trigger the bash bug anymore.
7019 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
7020 use AS_INIT_WITH_SHELL_FN.
7021 * bin/autoconf.in, tests/wrapper.in: Regenerated.
7023 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

7051 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

7053 the 2003-05-22 change, which removed the older years from the list.
7054 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
7056 2004-01-27 Gary V. Vaughan <gary@gnu.org>

7096 sources.
7098 2004-01-26 Paul Eggert <eggert@twinsun.com>
7100 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
7101 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
7102 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
7103 not <inttypes.h>. Problem reported by Tim Mooney in
7104 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
7105 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
7106 Likewise.
7108 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
7109 otherwise "make check" fails because it forbids cmp (I guess
7110 because cmp treats files as binary on DOS-like systems).
7112 * tests/mktests.sh: Update copyright date to 2004, since some tests
7113 have changed in 2004.
7115 2004-01-23 Gary V. Vaughan <gary@gnu.org>

7121 * NEWS: Updated.
7123 2004-01-15 Paul Eggert <eggert@twinsun.com>
7125 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
7126 -std1 disables some useful extensions on Tru64. Problem reported
7127 by N. Lichtmaier in
7128 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
7130 2004-01-14 Paul Eggert <eggert@twinsun.com>
7132 * doc/autoconf.texi (Programming in M4sh): Document that
7133 AS_MKDIR_P succeeds if the destination is a symbolic link
7134 to an existing directory.
7135 (Limitations of Usual Tools): Note that mkdir -p might not
7136 succeed on symlinks to directories.
7138 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
7140 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
7141 * bin/autoheader.in: Grammar fix in message.
7142 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):

7150 2004-01-10 Jim Meyering <jim@meyering.net>
7152 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
7154 2004-01-09 Paul Eggert <eggert@twinsun.com>
7156 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
7157 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
7158 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
7159 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
7160 AC_COMPILE_IFELSE, since we now assume our caller invokes
7161 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
7162 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
7163 of AC_RUN_IFELSE; this avoids the warning mentioned above.
7164 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
7166 2004-01-07 Paul Eggert <eggert@twinsun.com>
7168 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
7169 `"'...'"`, as it's confusing (and I suspect it may not work on
7170 some platforms). The code was incorrect anyway, as it assumed
7171 that \$ evaluated to itself in that context. Reported by
7172 Alexandre Duret-Lutz.
7174 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
7176 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
7177 and _LT_AC_TAGCONFIG.
7179 2004-01-06 Paul Eggert <eggert@twinsun.com>
7181 * doc/autoconf.texi (One Macro Call): Fix an incorrect
7182 example, and add more examples. Reported by Eric Sunshine.
7184 2004-01-05 Paul Eggert <eggert@twinsun.com>
7186 * doc/autoconf.texi (Limitations of Usual Tools):
7187 Remove warning against "rm -fr" introduced yesterday; it
7188 was a false alarm.
7190 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
7191 autoscan, autoupdate, ifnames): Don't use chmod -w.
7192 * lib/Makefile.am (autom4te.cfg): Likewise.
7193 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
7194 "chmod -w".

7197 Paolo Bonzini <bonzini@gnu.org>
7199 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
7200 by doing lineno substitution only on lines containing "$LINENO".
7202 2004-01-04 Paul Eggert <eggert@twinsun.com>
7204 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
7205 Use "rm -f" to remove conftest.sed, not plain "rm".
7206 Bug reported by David Relson in
7207 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
7209 * Makefile.am (autom4te-update):
7210 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
7211 * Makefile.maint (my-distcheck, do-po-update): Likewise.
7212 * doc/autoconf.texi (Guidelines): Likewise.

7222 Warn against "rm -fr".
7224 2004-01-03 Paul Eggert <eggert@twinsun.com>
7226 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
7227 -c -o might not work. From a suggestion by Kevin Ryde.
7228 (C Compiler, Generating Sources, Limitations
7229 of Usual Tools, Limitations of Make, Making testsuite Scripts):
7230 Don't put '-o' after non-options, as POSIX doesn't allow this.
7231 Mention that cc's name might be gcc or c89 or whatever.
7233 2004-01-04 Kevin Ryde <user42@zip.com.au>
7235 * doc/autoconf.texi: Add various further index entries.
7237 2003-12-29 Paul Eggert <eggert@twinsun.com>
7239 * bin/autoreconf.in (autoreconf_current_directory):
7240 Fix typo: mkdir without umask arg.
7242 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
7244 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
7245 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
7246 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
7247 explanation clearer.
7249 2003-12-24 Andreas Schwab <schwab@suse.de>
7251 * doc/autoconf.texi (Default Includes): Fix misspelling of
7252 AC_INCLUDES_DEFAULT.
7254 2003-12-03 Paolo Bonzini <bonzini@gnu.org>

7298 * config/announce-gen (&print_locations, &print_signatures)
7299 (&sizes): New.
7300 Use them.

7302 them on the fly.
7304 2003-11-24 Akim Demaille <akim@epita.fr>
7306 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can
7307 override some files.
7308 (Input): AC_CONFIG_AUX_DIR(aux) is a bad idea on DOS.
7309 From Debian Autoconf 2.58.

7349 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
7350 than $target since the latter is not usual, add guidelines on when to

7355 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

7375 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

7510 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
7511 cross test.
7513 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
7515 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
7516 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

7528 Problems reported by Eric Sunshine.
7530 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
7532 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
7533 -mGLOB_options_string stuff for Intel ifc, which can cause

7539 * doc/autoconf.texi: Document new FC Fortran macros.

7557 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
7558 cache variable instead of $G77 to decide whether to include -O2,
7559 since $G77 is specific to Fortran 77.

7563 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

7566 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7568 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
7569 arguments so that it can be used with syntax identical to
7570 AC_PROG_F77, and so that we can more easily decide to
7571 remove/deprecate the DIALECT optional argument in the future if it
7572 proves troublesome.
7573 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
7574 non-freeform-supporting compilers. Document freeform flags.
7576 2003-10-03 Akim Demaille <akim@epita.fr>
7578 * configure.ac: Look for emacs, not macs.
7579 Reported by Eric Sunshine.
7581 2003-10-03 Akim Demaille <akim@epita.fr>
7583 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
7584 * bin/autoreconf.in (autoreconf_current_directory): Create the

7586 Suggested by Alexandre Duret-Lutz.
7588 2003-10-03 Akim Demaille <akim@epita.fr>
7590 * configure.ac: Quotation and formatting changes.

7612 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
7613 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.

7620 (@news_file): this.
7622 2003-09-30 Nicolas Joly <njoly@pasteur.fr>

7625 have been created when invoking the compiler.

7639 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
7640 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
7641 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
7643 2003-09-26 Akim Demaille <akim@epita.fr>
7645 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
7646 directory for AC_CONFIG_COMMANDS' first argument exists.
7647 This makes valid the invocation of _AC_SRCPATH that follows.
7648 Reported by Eric Sunshine.
7649 * doc/autoconf.texi (Configuration Commands): Adjust.
7651 2003-09-26 Akim Demaille <akim@epita.fr>
7653 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
7654 Reported by Ralf Corsepius.
7656 2003-09-26 Akim Demaille <akim@epita.fr>
7658 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
7659 arguments.
7660 Actually, use AU_ALIAS.
7661 From Bruno Haible.

7670 2003-09-26 Akim Demaille <akim@epita.fr>
7672 The test suite are sometimes assigning timings incorrectly.
7673 Reported by Henk Krus.
7674 Diagnosed by Nicolas Joly.
7676 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
7677 AT_help_all.
7678 Instead of making AT_help a sequence of assignments to grow
7679 $at_help_all, just make AT_help_all be the growing contents of
7680 $at_help_all, and make a single assignment in...
7681 (AT_INIT): here.
7682 (at_times_skip): Flip the meaning and rename as...
7683 (at_times_p): this.
7684 (AT_INIT): When summarizing the test that ran, remove
7685 $at_times_file after use, and check it is present before trying to
7686 use it.

7694 (ifnames): chmod -w.
7695 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
7696 executables, not bin/ executables! Otherwise all the magic needed
7697 to find non installed files is turned off. This caused a failure
7698 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
7699 as found in its environment (sent by tests/autoreconf): pointing
7700 to bin/autom4te that could not find its files.
7701 * tests/mktests.sh: Force the replacement of generated files, for
7702 the sake of "mv" program that are interactive when overwriting a
7703 -w file.
7704 * config/install-sh: Upgrade from CVS Automake.
7706 2003-09-23 Paul Eggert <eggert@twinsun.com>

7712 Paul Eggert <eggert@twinsun.com>
7714 Trivial change to support GCC's configuration procedure.
7715 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
7716 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
7717 about inconsistency if the preprocessor is set to give errors for
7718 any warning.
7719 * doc/autoconf.texi (C Compiler Characteristics): Document this.
7721 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

7737 2003-09-12 Akim Demaille <akim@epita.fr>
7739 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
7740 not asm/types.h.
7742 2003-09-11 Akim Demaille <akim@epita.fr>
7744 * doc/autoconf.texi (Header Portability): linux/random.h.
7745 From Peter Hendrickson.
7747 2003-09-10 Akim Demaille <akim@epita.fr>

7777 2003-09-05 Paul Eggert <eggert@twinsun.com>
7779 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
7780 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
7782 2003-09-04 Akim Demaille <akim@epita.fr>
7784 * tests/mktests.sh (ac_exclude_list): Fix the filtering of

7800 unchanged, and continues to support Fortran 77. New FC macros
7801 correspond to all the old F77 macros, with output variables FC,
7802 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
7803 available dialect, but older dialects can be specified. There are
7804 new macros AC_FC_SRCEXT to set the source extension, and
7805 AC_FC_FREEFORM to accept free-form source files.

7835 Document problems with timestamp resolution that 'make', 'cp -p', and
7836 'touch -r' have.
7838 2003-08-27 Akim Demaille <akim@epita.fr>
7840 * tests/m4sugar.at (cross_warning): Make sure to enable the
7841 output, so that we can track spurious m4sugar output.

7843 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
7844 are defaulted by AT_CHECK anyway.
7845 Use AT_CHECK_AUTOM4TE.
7846 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
7847 missing dnl.
7849 2003-08-27 Akim Demaille <akim@epita.fr>
7851 * bin/autoheader.in: Issue the "Using auxiliary..." message only

7898 2003-08-22 Akim Demaille <akim@epita.fr>
7900 Output stack traces in warnings.
7902 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.

7904 (m4_warn): Pass the call stack to _m4_warn.
7905 * bin/autom4te.in: Adjust to output the call stack.
7906 * tests/m4sugar.at (m4@&t@_warn): Adjust.
7908 2003-08-22 Akim Demaille <akim@epita.fr>

7915 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
7916 (&verbose): Remove.
7917 (&getopt): Adjust the note and verb channels, depending upon
7918 --verbose.

7920 * bin/autoupdate.in: Adjust.
7921 Use &verb, not &verbose.
7923 2003-08-21 Akim Demaille <akim@epita.fr>
7925 * bin/autoheader.in (&parse_args): Use &parse_warnings and

7929 * lib/Autom4te/General.pm: Don't export error: you don't own it.
7931 2003-08-21 Akim Demaille <akim@epita.fr>
7933 First stab at preserving warnings between calls to autom4te,
7934 including when the cache is used.
7936 There are still several issues: (i) there are too many runs of m4
7937 (one for include, one for warnings, and some more), (ii) warnings
7938 spreading on several lines are not handled gracefully, (iii) the
7939 code meant to have the call stack display for errors does not work
7940 (its handling should move from m4 to autom4te).
7942 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7943 Use them.
7944 (@preselect): Add m4_warn.
7945 ($exit_status): Remove, use $exit_code.
7946 ($help): Use Autom4te::ChannelDefs::usage.
7947 (&handle_m4): No longer define the m4_warnings.
7948 At each run, extract and report the warnings.
7949 Always cache the result, including if the exit status is on
7950 failure, since if nothing changes, we should result in the same
7951 failure, hence we can use the cache.
7952 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7953 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7954 Remove.
7955 (m4_warn): Redefine as a do-nothing: it is its invocation that
7956 matters, as warnings are now reported via traces.
7957 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7958 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7959 the latter reveals calls to the former.
7961 Adjust the tests.
7963 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
7965 2003-08-21 Akim Demaille <akim@epita.fr>
7967 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
7968 Use them.
7970 2003-08-21 Akim Demaille <akim@epita.fr>
7972 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
7973 forward order.
7974 * lib/Autom4te/ChannelDefs.pm: Doc typos.
7975 (&parse_warnings): Accept a list of warning requests.
7976 (&usage): Return a string, not a side effect.
7977 (cross): New warning category.
7979 2003-08-21 Akim Demaille <akim@epita.fr>
7981 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
7982 (&require_configure_ac): Accept an optional directory argument.
7983 ($configure_ac): Remove.
7984 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
7985 (&catfile): Remove.
7986 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
7987 * bin/autoscan.in: Adjust.
7989 2003-08-20 Akim Demaille <akim@epita.fr>
7991 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
7992 Reported by Alexandre Duret-Lutz.
7994 2003-08-20 Akim Demaille <akim@epita.fr>
7996 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7997 * bin/autom4te: Adjust.
7998 In particular, be Autoconf tools are really silent when properly
7999 working, bind the verbosity of the 'note' channel to $verbose.
8000 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
8001 (&xsystem, &contents): Remove, since they are exported by...
8002 * lib/Autom4te/FileUtils.pm: this.
8003 More perldoc.
8004 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
8005 * lib/Autom4te/FileUtils.pm: here.
8007 2003-08-20 Akim Demaille <akim@epita.fr>
8009 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
8010 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

8062 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
8063 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
8064 shorter column three. Add DESCRIPTION to log file content.
8066 2003-08-13 Derek Price <derek@ximbiot.com>
8068 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
8069 output.

8077 2003-08-07 Derek Price <derek@ximbiot.com>
8079 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
8080 (AT_CHECK_NOESCAPE): ...to this new macro.
8082 2003-07-31 Paul Eggert <eggert@twinsun.com>
8084 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
8085 in Bash 2.01. Problem reported by Brian Gough in
8086 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.

8096 inside '#ifndef __cplusplus'. Problem reported by
8097 Bob Friesenhahn.
8099 2003-07-06 Bill Clarke <llib@computer.org>
8101 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
8102 'long', not 'int', for benefit of Sun's recent C++ compilers
8103 (trivial change). See:
8104 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
8105 (This really should be 'intptr_t', not 'long', but that would
8106 take more work.)
8108 2003-06-25 Akim Demaille <akim@epita.fr>
8110 * lib/Makefile.am (autom4te.cfg): Make it read only.
8111 Depend on Makefile since it contains substitutions.

8124 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
8125 not all of them. This fixes 1. the fact that when testing
8126 Autoconf there are many many config.log, 2. the incorrect use of
8127 top_srcdir to find config.log.
8128 Don't mix the detailed output of failed test with the summary of
8129 failures. Rather, append detailed log afterwards.
8131 2003-06-23 Akim Demaille <akim@epita.fr>
8133 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

8216 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
8218 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
8219 Do not call `_exit()', simply modify `$?'.

8227 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
8228 the middle of a line).
8229 * lib/m4sugar/m4sugar.m4: Likewise.
8230 Remove useless spaces in comments.
8232 2003-05-23 Akim Demaille <akim@epita.fr>
8234 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
8235 exit 63, so that we (or Automake's "missing") can tell the
8236 difference with a plain failure.
8237 * doc/autoconf.texi (Notices): Adjust.
8239 2003-05-23 Akim Demaille <akim@epita.fr>
8241 * Makefile.am, bin/Makefile.am, config/Makefile.am,
8242 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
8243 White spaces cleanup.
8245 2003-05-22 Jim Meyering <jim@meyering.net>
8246 Paul Eggert <eggert@twinsun.com>
8248 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
8249 Remove `#include <stdlib.h>' from the list; we should never
8250 make confdefs.h include <stdlib.h> or <cstdlib>, because the
8251 resulting namespace pollution would cause other tests to fail.
8252 Configure scripts run with some older versions of g++ and HP's
8253 aCC would fail due to such an #include. Problems reported by
8254 Matthew Mueller in <http://bugs.debian.org/120704> and by
8255 Keith Bostic in
8256 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
8257 In the test, use the test declaration before including <stdlib.h>,
8258 as that's closer to how it'll be used.
8260 2003-05-23 Akim Demaille <akim@epita.fr>
8262 * doc/autoconf.texi (Header Portability): ucred.h.
8263 From Ian Redfern.
8265 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8267 Overhaul Autotest's logging: generate separate log files
8268 in testsuite.dir/NNN/testsuite.log, and append them to
8269 testsuite.log instead of re-running the test verbosely.
8271 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
8272 file descriptor, write 0 to at_status_file instead of setting
8273 at_status=0, initialize some new variables (at_status_file,
8274 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
8275 to rerun the tests, instead append the at_group_log to the
8276 at_suite_log when a test fails.
8277 (AT_SETUP): pipe the test case's output into at_tee_pipe,
8278 with the AS_MESSAGE_LOG_FD redirected to stdout.
8279 (AT_CLEANUP): save the output status in $at_status_file
8280 and restore it, redirect the AS_MESSAGE_LOG_FD back to
8281 its original place.
8282 (AT_CHECK): since tests are run with a redirected stdout,
8283 and used to be re-run in verbose mode, turn some $at_verbose
8284 into echo, and don't redirect the output of testing stdout
8285 and stderr.
8287 * lib/autotest/autoconf.texi (testsuite Scripts): Update
8288 the name of the debugging directory and information about
8289 its contents.
8291 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8293 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
8294 parameter.
8296 2003-05-22 Akim Demaille <akim@epita.fr>
8298 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4

8363 memcmp be declared before being tested.
8364 Reported by Sander Niemeijer.
8365 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.

8367 AC_INCLUDES_DEFAULT.
8369 2003-05-17 Akim Demaille <akim@epita.fr>

8378 user name space clashes.
8379 Reported by Bruno Haible.

8401 From Matthias Andree.
8403 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>

8406 and truncate.
8408 2003-05-06 Akim Demaille <akim@epita.fr>
8410 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
8411 longer updates aclocal.m4 if useless, (ii) if a file m4_included
8412 by aclocal.m4 is changed it might require the importing of another
8413 m4 extension file, i.e., aclocal must be run.
8415 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
8416 (&parse_args): Use --force with aclocal if required and supported.
8417 (&autoreconf_current_directory): Use &run_aclocal.

8424 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
8425 argument instead of a file name, so that the request file remains
8426 open during the whole autom4te run.
8427 ($icache_file): New.
8428 (&freeze): Lock the $icache_file.
8430 2003-04-29 Derek Price <derek@ximbiot.com>
8432 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
8433 seperator with m4_append_uniq(). It doesn't work.
8434 (AT_CLEANUP): Add `;' to end of at_help_all.
8435 (AT_INIT): Allow --keywords to be specified more than once. When
8436 grepping $at_help_all for keywords, use the field and keyword
8437 seperators to ensure a complete keyword match. Alter at_prev handling
8438 to support the new --keywords behavior.
8440 2003-04-27 Karl Berry <karl@freefriends.org>
8442 * doc/autoconf.texi: Make the dir entries in the autoconf manual
8443 align better with others. I also made some of the individual
8444 entries on one line, for brevity and to make it easier for me to
8445 sort my dir-example file in the Texinfo distribution :).
8447 2003-04-12 Jim Meyering <jim@meyering.net>
8449 * NEWS: Mention the new macro.

8485 New.
8486 Use them.

8488 (TEXI2DVI): Make it --batch.
8490 2003-03-31 Derek Price <derek@ximbiot.com>
8492 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
8493 which removed the main loop.
8494 Thanks to Akim Demaille.
8496 2003-03-29 Akim Demaille <akim@epita.fr>

8499 that starts a GUI.
8500 From Ilya Zakharevich.
8502 2003-03-29 Akim Demaille <akim@epita.fr>

8506 Suggested by Paul Eggert.
8508 2003-03-28 Akim Demaille <akim@epita.fr>
8510 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest

8512 header causes problems.
8514 2003-03-28 Akim Demaille <akim@epita.fr>
8516 * tests/torture.at (Configuring subdirectories): Require aclocal
8517 1.4, otherwise the test fails, as it does support configure.ac.
8518 This fixes the "test 40 failed" bug reports.

8532 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
8533 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
8534 use new diversions in preparation for accepting new arguments and

8587 * doc/autoconf.texi (Limitations of Make): Remove the section
8588 about `$<' in inference rules, it was a bogus interpretation of
8589 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
8590 Tru64 make in the "target lookup" section.
8591 (Automake): Automake 1.5+ no longer requires special tools to be
8592 present on the developer's host.

8610 ${ac_make}.
8612 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
8613 When constructing paths with IFS=:, quote the path. If we're

8633 to fix a mismatch between example and discussion.
8635 2003-02-24 Kevin Ryde <user42@zip.com.au>
8637 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
8638 format starting with "-".
8640 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
8642 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
8643 is not portable inside Makefile.
8645 2003-02-20 Akim Demaille <akim@epita.fr>
8647 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
8648 compiler says yeah, but preproc says nope, compiler is right.
8649 Conversely, prompt the reader to send a bug report to the
8650 maintainers of the package, not of Autoconf.
8652 2003-02-20 Klee Dienes <kdienes@apple.com>
8654 * bin/autoreconf.in (autoreconf_current_directory): Properly

8665 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
8666 innocuous variant befor including <limits.h> or <assert.h>. This
8667 works around a bug reported by Albert Chin: HP-UX 11i
8668 (and earlier versions) have a <limits.h> that declares
8669 gettimeofday and many other functions.
8671 2002-12-03 Paul Eggert <eggert@twinsun.com>
8673 Version 2.57.
8675 * NEWS, configure.ac: Update version.

8679 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
8680 nontrivially in main's body, so that f's external declaration is
8681 not optimized away in AIX. This should fix the bug reported by
8682 Martin Frydl in
8683 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
8685 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
8686 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
8687 defined, to support freestanding compilers. This should fix the
8688 bug reported by Momchil Velkov in
8689 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
8691 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
8692 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
8693 obsolete AC_CHECK_TYPE. The missing empty arg was reported
8694 by Simon Josefsson in
8695 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
8697 * Makefile.maint (www-gnu): New macro.
8698 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
8699 the location has moved.
8701 2002-12-02 Martin Frydl <martin@systinet.com>
8703 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
8704 \(.*\) match is too long and there is something more to be checked.
8705 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

8723 Update from masters.
8725 2002-11-14 Akim Demaille <akim@epita.fr>
8727 * Makefile.maint: Sync with Bison, i.e.:
8728 (po-check): Scan .l and .y files instead of the
8729 .c and the .h files that they generate. This fixes the bug
8730 reported by Tim Van Holder in:
8731 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
8732 Look for N_ as well as for _. Try to avoid matching #define for
8733 N_ and _.
8734 From Paul Eggert.
8736 2002-11-14 Akim Demaille <akim@epita.fr>
8738 * doc/autoconf.texi (C Compiler): Compiling several files at once.

8746 2002-11-14 Kevin Ryde <user42@zip.com.au>
8748 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
8749 than assigning in main, to avoid HP cc +O3 optimizing it away.
8751 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
8753 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
8754 option. Process --recheck after parsing all options. Pass -q
8755 option to configure on --recheck.
8756 (AC_OUTPUT): Pass -q from configure to config.status.
8757 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from

8759 * doc/autoconf.texi (config.status Invocation): Document
8760 config.status -q option.
8762 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

8789 2002-11-05 Akim Demaille <akim@epita.fr>
8791 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
8792 Remove.
8793 We _have_ to stop using the old compatibility scheme that tried to
8794 avoid useless backslashes because Libtool 1.4.3 contains a
8795 AC_DEFINE([error_t], [int],
8796 [Define to a type to use for \`error_t' if it is not
8797 otherwise available.])
8798 We _have_ to quote the single quote and backslashes with \. The
8799 old compatibility scheme saw that ` was backslashed, and therefore
8800 did not quote the single quote. Hence before this patch, Autoconf
8801 was not compatible with Libtool.
8803 2002-11-04 Paul Eggert <eggert@twinsun.com>
8805 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

8843 2002-10-31 Akim Demaille <akim@epita.fr>
8845 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
8846 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
8847 Make variable, not a shell variable.
8848 Suggested by Bruno Haible.
8850 2002-10-31 Akim Demaille <akim@epita.fr>
8852 * bin/autom4te.in (load_configuration): Reject #args out of any
8853 language.

8869 Suggested by Tim van Holder.

8874 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
8875 Problem reported by Bruno Haible.
8877 2002-10-29 Akim Demaille <akim@epita.fr>
8879 * doc/autoconf.texi (Header Templates): Put also in words what the
8880 pictures says to assist free style readers.
8881 (Customizing autom4te): s/--cache=/--cache /.
8883 2002-10-29 Akim Demaille <akim@epita.fr>

9192 Reported by Alexandre Duret-Lutz.
9194 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

9211 (&autoreconf): Report the directories we enter *and leave*, so
9212 that error messages can be easily located, and use GNU Make
9213 format, so that Emacs' compile mode understands us.
9214 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
9215 if some file was changed instead of `print'.
9216 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
9217 (&parse_args): Remove the dead options.
9218 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
9219 autoheader's quiet mode.
9220 (AT_CHECK_AUTOUPDATE): Likewise.
9221 * tests/tools.at (autoupdate): Adjust.
9222 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
9224 2002-10-11 Akim Demaille <akim@epita.fr>
9226 No longer use CPP to check for the existing of headers: use CC to
9227 check for compilability.
9229 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
9230 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
9231 (_AC_CHECK_HEADER_NEW): Rename as...
9232 (AC_CHECK_HEADER): this.
9234 * lib/autotest/general.m4 (AT_INIT): Include the failed test
9235 numbers in the Subject suggestion.
9237 2002-10-11 Akim Demaille <akim@epita.fr>
9239 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
9240 Suggest using AC_CHECK_DECLS instead.
9242 2002-10-11 Akim Demaille <akim@epita.fr>
9244 * tests/torture.at (AC_ARG_VAR): Have configure report the value
9245 of `precious'.
9247 2002-10-11 Akim Demaille <akim@epita.fr>
9249 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
9250 file name to enable parallel executions.
9251 From Sam Varshavchik.
9253 2002-10-08 Akim Demaille <akim@epita.fr>
9255 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
9256 aclocal invocation, as Gettext macros might not be visible to
9257 aclocal.
9258 Instead of blindly running autopoint, scan configure.ac (not the
9259 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
9260 Reported by Paul D. Smith.
9262 2002-10-08 Paul Eggert <eggert@twinsun.com>
9264 Work around problems found when POSIXLY_CORRECT=1 is set.
9265 None of this seems to have anything to do with POSIX, really,
9266 but it's how Perl getopt works.
9267 * bin/autom4te.in (parse_args): Configure GetOpt with
9268 "permute", too.
9269 * doc/autoconf.texi (Invoking autom4te):
9270 --warning -> --warnings.
9271 * lib/autom4te.in: --warning -> --warnings.
9273 2002-09-28 Akim Demaille <akim@epita.fr>
9275 * doc/autoconf.texi (autom4te.cache): New section.
9277 2002-09-28 Akim Demaille <akim@epita.fr>
9279 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
9280 (Automake-preselections): Update.
9281 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
9283 2002-09-28 Akim Demaille <akim@epita.fr>
9285 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
9286 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
9287 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9288 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
9290 2002-09-28 Akim Demaille <akim@epita.fr>
9292 * tests/torture.at (Configuring subdirectories): Be robust to
9293 users who use config.site to require for a cache: in this case,
9294 the two last configure runs, using two different sets of
9295 arguments, trigger a legitimate error.
9297 2002-09-28 Akim Demaille <akim@epita.fr>
9299 * tests/m4sh.at (Functions Support, Functions and return Support):
9300 New.
9302 2002-09-28 Akim Demaille <akim@epita.fr>
9304 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
9305 autoheader are Perl programs.
9306 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
9307 (autom4te): Specify that the sources are in the $srcdir.
9308 * doc/autoconf.texi (Installation Directory Variables): Adjust.
9310 2002-09-28 Akim Demaille <akim@epita.fr>
9312 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
9313 (tm_zone): Move their rules to...
9314 * lib/autoconf/types.m4: here, using AN_ macros.
9315 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
9316 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
9317 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
9318 * lib/autoconf/programs.m4: here.
9319 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
9320 (ETAGS_FOR_AUTOCONF): New.
9321 Use it.
9323 2002-09-28 Akim Demaille <akim@epita.fr>
9325 * lib/autoconf/autoscan.m4: New file.
9326 * lib/autoconf/autoconf.m4: Include it.
9327 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
9328 that were listed in the original autoscan.list.
9329 * lib/autoconf/headers.m4: Similarly with headers.
9330 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
9331 (.m4.m4f): Don't pass --prepend-include, since that's done by
9332 tests/autom4te itself.
9333 * lib/autoscan/Makefile.am: Include freeze.mk.
9334 (autoscan.list): New target --this file is no longer a source.
9335 (autoscan.pre): New file.
9337 2002-09-28 Akim Demaille <akim@epita.fr>
9339 * bin/autoscan.in (@kinds): Make them singular.
9340 Adjust all uses.
9341 (&init_tables): When --debug, report the list of rules to ease
9342 tracking changes in autoscan.list.
9343 * lib/autoscan/autoscan.list (function): Strip comments, sort.
9345 2002-09-28 Akim Demaille <akim@epita.fr>
9347 * lib/autoscan/functions, lib/autoscan/headers,
9348 * lib/autoscan/identifiers, lib/autoscan/makevars,
9349 * lib/autoscan/programs: Merge into...
9350 * lib/autoscan/autoscan.list: this.
9351 * bin/autoscan.in (&init_tables): Adjust.
9353 2002-09-28 Akim Demaille <akim@epita.fr>
9355 * lib/autoscan/functions, lib/autoscan/headers,
9356 * lib/autoscan/identifiers, lib/autoscan/makevars,
9357 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
9358 `functions' line is now prefixed with `function:'.
9359 * bin/autoscan.in (&init_tables): Adjust.
9361 2002-09-28 Akim Demaille <akim@epita.fr>
9363 From now on, autoscan files must always map a macro name to a
9364 word: there is no `default' macro for autoscan.
9366 * bin/autoscan.in (&init_tables): Reject entries with no macro at
9367 all.
9368 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
9369 explicit.
9371 2002-09-28 Akim Demaille <akim@epita.fr>
9373 * bin/autoscan.in (%c_keywords): Remove.
9374 (&used): Keep only track of the words we might be interested in.
9375 (&output_kind): It is no longer needed to look for non active
9376 checks.
9378 2002-09-27 Akim Demaille <akim@epita.fr>
9380 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
9381 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
9382 * lib/autoscan/functions: Adjust.
9383 * doc/autoconf.texi (Particular Functions): Adjust.
9385 2002-09-27 Akim Demaille <akim@epita.fr>
9387 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
9388 from /tmp.
9389 Thanks to Bill Moseley and Paul Eggert.
9390 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
9391 the tmpdir must be created.
9392 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
9393 dir be in the build tree, instead of $TMPDIR.
9395 2002-09-27 Akim Demaille <akim@epita.fr>
9397 * bin/autoscan.in: Improve the comments.
9398 (&parse_args): Drop obsolete undocumented options.
9399 (&output_kind): Output warnings.
9400 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
9401 (getwd): Trigger a warning.
9403 2002-09-26 Akim Demaille <akim@epita.fr>
9405 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
9406 Reported by Ralf Corsepius.
9407 * doc/autoconf.texi (autoreconf Invocation): Likewise.
9409 2002-09-26 Akim Demaille <akim@epita.fr>
9411 Single suffix rules and seperated dependencies are not portable.
9413 * doc/autoconf.texi (Installation Directory Variables): Update.
9414 (Limitations of Make): Some about `Single Suffix Rules and
9415 Separated Dependencies'.
9416 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9417 (ifnames, autoscan, autom4te): Un-factor into several rules.
9419 2002-09-25 Paul Eggert <eggert@twinsun.com>
9421 * BUGS (Interoperability bugs): New section. Mention libtool
9422 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
9424 2002-09-24 Paul Eggert <eggert@twinsun.com>
9426 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
9427 make handles suffix-rules differently from GNU make.
9429 * bin/Makefile.am (SUFFIXES, .in): Remove.
9430 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
9431 Move the body of the old .in rule here.
9433 2002-09-16 Akim Demaille <akim@epita.fr>
9435 i960 compilers create `b.out' files by default.
9436 Reported by Ralf Corsepius.
9438 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
9439 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
9441 2002-09-13 Paul Eggert <eggert@twinsun.com>
9443 * doc/autoconf.texi (Particular Headers): Remove obsolete
9444 reference to `struct timezone' in the description of
9445 AC_HEADER_TIME.
9447 2002-09-13 Akim Demaille <akim@epita.fr>
9449 Version 2.54.
9451 * config/config.sub, config/config.guess: Update.
9452 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
9453 * Makefile.am: Adjust.
9455 2002-09-13 Akim Demaille <akim@epita.fr>
9457 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
9458 reading config.log when the compiler is rejected.
9459 Suggested by Guido Draheim.
9461 2002-09-13 Akim Demaille <akim@epita.fr>
9463 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
9464 (chdir_init) might hang when stat'ing mounted directories.
9465 Reported by Vance Shipley.
9467 2002-09-12 Akim Demaille <akim@epita.fr>
9469 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
9470 the lists.
9472 2002-09-12 Akim Demaille <akim@epita.fr>
9474 * doc/autoconf.texi (Defining Symbols): Present two different
9475 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
9476 difference between 1 argument calls, and 2-3 argument calls.
9478 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
9480 * doc/autoconf.texi: Review grammar and punctuation.
9482 2002-09-11 Paul Eggert <eggert@twinsun.com>
9484 * doc/autoconf.texi: Fix minor formatting, spelling, and
9485 grammatical typos.
9486 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
9487 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
9488 is obsolescent.
9490 2002-09-11 Akim Demaille <akim@epita.fr>
9492 * doc/autoconf.texi (Questions): Rename as...
9493 (FAQ): this.
9494 (Defining Directories): New.
9496 2002-09-09 Akim Demaille <akim@epita.fr>
9498 * doc/autoconf.texi (Making testsuite Scripts): Update.
9499 Suggested by Nishio Futoshi.
9501 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
9503 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
9504 plain `@' is wanted.
9506 2002-09-09 Akim Demaille <akim@epita.fr>
9508 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
9509 `duplicates', since the algorithm was too naive and could keep
9510 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
9511 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
9512 Reported by Ralf Corsepius.
9513 * tests/torture.at (Configuring subdirectories): Exercise these
9514 cases.
9516 2002-09-09 Akim Demaille <akim@epita.fr>
9518 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
9519 looking for a replacement file.
9520 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
9521 directory is relative.
9522 * doc/autoconf.texi (Generic Functions): Clarify the replacement
9523 directory definition.
9524 Reported by Andreas Schwab and Jim Meyering.
9526 2002-09-06 Akim Demaille <akim@epita.fr>
9528 * doc/autoconf.texi (Setting Output Variables): Clarify what
9529 precious variables are.
9530 Suggested by Pontus Skoeld.
9532 2002-09-05 Akim Demaille <akim@epita.fr>
9534 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9535 (ifnames, autoscan, autom4te): Since we don't only depend on
9536 configure.ac variables (such as VERSION etc.), but also on prefix
9537 and so forth, depend on Makefile, not configure.ac.
9538 Reported by Alexandre Duret-Lutz.
9539 * doc/autoconf.texi (Installation Directory Variables): Adjust.
9541 2002-09-05 Kevin Ryde <user42@zip.com.au>
9543 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
9544 doesn't seem to be confined to ia64, just say "some versions".
9546 2002-09-04 Akim Demaille <akim@epita.fr>
9548 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
9549 Automake 1.6c.
9550 * Makefile.am (maintainer-clean-local): Remove.
9551 (MAINTAINERCLEANFILES): Remove COPYING.
9553 2002-09-03 Paul Eggert <eggert@twinsun.com>
9555 * doc/autoconf.texi (Configuration Commands): Remove obsolete
9556 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
9557 Brinkmann.
9559 2002-09-03 Akim Demaille <akim@epita.fr>
9561 * configure.ac: Bump to 2.53d.
9562 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
9563 as of today, on Automake's team suggestion.
9565 2002-09-03 Akim Demaille <akim@epita.fr>
9567 Version 2.53c.
9569 2002-09-02 Akim Demaille <akim@epita.fr>
9571 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
9572 SITE_MACRO_DIR.
9573 * configure.ac: Disable SITE_MACRO_DIR.
9575 2002-09-02 Jim Meyering <meyering@lucent.com>
9577 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
9578 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
9579 Also, tweak grammar: s/make sure to/be sure to/.
9581 2002-09-02 Paul Eggert <eggert@twinsun.com>
9583 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
9584 directory names are generally preferable to physical names.
9586 2002-09-02 Akim Demaille <akim@epita.fr>
9588 * lib/Autom4te/General.pm (&update_file): s/die/error/.
9589 Reported by Raja R. Harinath.
9590 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
9591 * bin/autoupdate.in: Use error instead of die.
9593 2002-09-01 Paul Eggert <eggert@twinsun.com>
9595 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
9596 ordinary shell concatenation rather than echo+tr+sed command that
9597 runs afoul of a long-line-related sed bug in Solaris 8.
9599 * bin/autoheader.in (parse_args): --warning -> --warnings.
9601 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
9602 stdout, as traditional "ls" does.
9603 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
9604 _AC_COMPILER_EXEEXT_O): Likewise.
9605 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
9607 * bin/autoconf.as: Add --prepend-include option. This patch was
9608 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
9609 but bin/autoconf.in is generated automatically from bin/autoconf.as.
9611 * bin/autoconf.in, configure: Regenerate.
9613 * doc/autoconf.texi (Special Shell Variables): Mention
9614 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
9616 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
9617 MAILPATH and set PS1, PS2, PS4 to default values, to work
9618 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
9619 For LC_ALL etc, first try to set to "C" as POSIX requires and as
9620 the Autoconf documentation specifies; fall back to "unset" only if
9621 this fails. Use a shell for-loop for this rather than an m4 loop,
9622 to shorten the output script.
9624 2002-08-30 Paul Eggert <eggert@twinsun.com>
9626 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
9627 1003.1-2001's requirements for CDPATH. Give a simpler workaround
9628 for the CDPATH problem. Document PWD.
9629 (Limitations of Builtins): Document the problem that "cd $foo" and
9630 "ls $foo" may refer to different directories in shells conforming
9631 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
9632 example, since the old example is now out of date.
9634 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
9635 FOO" and "ls FOO" talk about different directories; this catches
9636 problems when POSIX 1003.1-2001 "cd" fails due to symlink
9637 spaghetti.
9639 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
9640 of rolling our own unset.
9641 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
9642 in practice we needn't worry about CDPATH if unset doesn't work.
9644 * Makefile.in, aclocal.m4, bin/Makefile.in,
9645 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
9646 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
9647 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
9648 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
9649 tests/Makefile.in: Regenerate with Automake 1.6.3.
9651 * config/config.guess, config/config.sub, config/mkinstalldirs:
9652 Update.
9654 * configure: Regenerate with self.
9656 2002-08-30 Kevin Ryde <user42@zip.com.au>
9658 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
9659 default output.
9661 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
9663 * bin/autom4te.in (Request::load): Correctly test for "do" read
9664 failure.
9666 2002-08-29 Akim Demaille <akim@epita.fr>
9668 * lib/Autom4te/General.pm (&xqx): New.
9669 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
9670 hand, which is not portable.
9671 (&error): New.
9672 * bin/autom4te.in: Use them.
9673 Use &error instead of die.
9674 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
9675 Adjust.
9677 2002-08-17 Paul Eggert <eggert@twinsun.com>
9679 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
9680 default list of compilers to try, since it was long ago superseded
9681 by the ksh fc builtin. Suggested by Steven G. Johnson.
9683 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
9685 * doc/autoconf.texi (Invoking autom4te): End the option table,
9686 fixing a bug introduced by the previous patch.
9687 (Limitations of Make): Add a 'target lookup' subentry in the
9688 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
9690 2002-07-29 Mark D. Roth <roth@feep.net>
9692 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
9693 options and use $AUTOM4TE_PATH.
9694 * doc/autoconf.texi: Remove documentation of autom4te
9695 --include-envvar and --site-macro-subdir options and document
9696 use of $AUTOM4TE_PATH.
9697 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir

9706 (AM_MAKEINFOFLAGS): New macro.
9707 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
9708 * Makefile.am (INSTALL): Use the new macros.
9709 Use -o rather than --output, since "missing" does not grok --output.
9711 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9713 * doc/autoconf.texi (Limitations of Make): Escaped newlines in

9719 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):

9724 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):

9853 2002-06-27 Paul Eggert <eggert@twinsun.com>
9855 * config/install-sh: Quote $src. Prefer || to test's -o option,
9856 as per "Limitations of Builtins".
9857 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
9858 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
9860 * tests/mktests.sh: Use grep instead of fgrep, as per
9861 "Limitations of Builtins".
9863 2002-06-15 Paul Eggert <eggert@twinsun.com>
9865 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,

9882 on Solaris 2.5.1.
9884 2002-06-11 Andreas Schwab <schwab@suse.de>
9886 * doc/autoconf.texi: Add more dir entries.
9888 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
9890 * bin/autom4te.in ($cache): Don't define using `$me', the name

9892 was installed.
9894 2002-06-07 Akim Demaille <akim@epita.fr>

9903 _AC_LANG_PROGRAM_C_F77_HOOKS.
9905 2002-06-07 Akim Demaille <akim@epita.fr>
9907 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
9908 rename as...
9909 (AC_REPLACE_FNMATCH): this.
9910 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
9911 AC_FUNC_FNMATCH_GNU.
9913 2002-06-07 Akim Demaille <akim@epita.fr>
9915 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the

9918 2002-06-07 Akim Demaille <akim@epita.fr>
9920 * bin/autom4te.in (warn_forbidden): When rejecting a token,

9922 Suggested by Adam J. Richter.
9924 2002-06-07 Akim Demaille <akim@epita.fr>
9926 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize

9929 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
9930 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
9931 Use ac_config_libobj_dir to find the replacement files.

9933 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
9934 (AC_REPLACE_FNMATCH_GNU): these.

9936 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.

9951 Update from masters.
9953 2002-05-29 Paul Eggert <eggert@twinsun.com>
9955 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
9956 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.

9988 from the default list of compilers to try. Suggested by
9989 Kate Hedstrom.
9990 * NEWS: Document the above.

9993 2002-05-17 Paul Eggert <eggert@twinsun.com>
9995 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
9996 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
9997 This improves on an earlier suggestion by H. Peter Anvin.
9999 2002-05-16 Paul Eggert <eggert@twinsun.com>
10001 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
10002 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
10003 Both macros now accept an optional source-dir arg.
10004 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
10006 * NEWS: Document this.
10007 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
10009 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
10010 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
10011 not for GNU extensions; this undoes part of the 2000-11-03 change,
10012 reverting to 2.13-compatible behavior.
10013 Add new optional argument DIR.
10014 (AC_FUNC_FNMATCH_GNU): New macro.
10016 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
10018 2002-05-08 Paul Eggert <eggert@twinsun.com>
10020 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
10021 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
10022 and it causes a 'test' syntax error if it fails.
10023 Bug reported by Stephen Gildea.
10025 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
10026 If prototypes are supported, use them to check this at compile-time,
10027 instead of trying to check it at run-time. If we must do a run-time
10028 check, assume that setvbuf is standard when cross-compiling, as
10029 nonstandard setvbuf occurs only on ancient and unlikely hosts.
10030 Bug reported by Paul D. Smith.
10032 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
10033 argument specifying location of getloadavg.c. This removes a
10034 FIXME. This idea was taken from Jim Meyering's implementation in
10035 textutils.
10036 * doc/autoconf.texi (Particular Functions): Document this.
10037 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
10038 that's what the code does; this fixes a bug reported by
10039 Paul D. Smith.
10041 2002-05-03 Akim Demaille <akim@epita.fr>
10043 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
10044 autopoint instead of gettextize.
10045 ($uses_alocal): Rename as...
10046 ($uses_aclocal): this.
10047 * doc/autoconf.texi (autoreconf Invocation): Adjust.
10048 Suggested by Bruno Haible.
10050 2002-05-03 Akim Demaille <akim@epita.fr>
10052 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
10054 2002-04-29 Paul Eggert <eggert@twinsun.com>
10056 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
10057 files to be 1 second older; just set them to be the same time.
10058 Also, sleep 1 second after the first aclocal, to work around
10059 problems with sub-second time stamps on the input files.
10061 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
10063 * doc/autoconf.texi: Mention "set -e -x" lossage
10064 under node "Limitations of Builtins".
10066 2002-04-29 Akim Demaille <akim@epita.fr>
10068 * doc/install.texi: Better wording for setting variables when
10069 running configure.
10070 From Christian Cornelssen.
10072 2002-04-29 Akim Demaille <akim@epita.fr>
10074 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
10075 of lack of $LINENO support, then the test will compare the $LINENO
10076 in testsuite vs. the lineno in the test file. This is wrong, of
10077 course.
10078 Be sure to protect it.
10079 Reported by Patrick Welche.
10081 2002-04-25 Akim Demaille <akim@epita.fr>
10083 * doc/autoconf.texi (Obsolete Macros): Typo.
10084 Reported by Vladimir Volovich.
10086 2002-04-25 Akim Demaille <akim@epita.fr>
10088 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
10089 than some of the input files, hence, on the second run of aclocal,
10090 if some of its input are younger, make them older.
10091 Suggested by Paul Eggert.
10093 2002-04-25 Akim Demaille <akim@epita.fr>
10095 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
10096 Thanks to Paul Eggert.
10098 2002-04-25 Akim Demaille <akim@epita.fr>
10100 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
10101 and ac_subst_vars be sh variables containing the list of
10102 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
10103 DEFAULT diversion.
10104 (_AC_INIT_PREPARE): Use them to log them.
10105 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
10106 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
10107 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
10108 _AC_SUBST_FILES and _AC_SUBST_VARS.
10109 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
10111 2002-04-24 Akim Demaille <akim@epita.fr>
10113 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
10114 autoheader, so that automake does not complain about a missing
10115 config.h.in that was to be created.
10117 2002-04-23 Akim Demaille <akim@epita.fr>
10119 * bin/autoheader.in (parse_args): --warning takes an argument.

10141 2002-04-22 Akim Demaille <akim@epita.fr>
10143 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.

10173 importantly, this makes sure that the copyright notices appear in
10174 all output formats. You probably need Texinfo 4.2 to generate
10175 the manual now.

10213 workaround for ${1+"$@"}.
10214 * doc/autoconf.texi (Shell Substitutions): Explain it.
10215 From Oliver Kiddle and Peter Stephenson.
10217 Have M4sh perform minimal shell sanitizing.
10219 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
10220 part into...
10221 (_AS_PREPARE): this new macro.
10222 (AS_PREPARE): New.
10223 (AS_INIT): Invoke AS_SHELL_SANITIZE.
10224 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
10226 Adjust Autoconf and Autotest.
10228 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
10229 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
10230 * lib/autotest/general.m4 (AT_INIT): Likewise.
10231 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10232 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
10233 AS_SHELL_SANITIZE.
10235 Use this M4sh to generate Autoconf's shell scripts.
10237 * tests/wrapsh.as: New, precursor of wrapsh.in.
10238 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
10239 on Autotest and M4sh.

10241 (wrapsh.in): New target.
10242 * bin/autoconf.as: New, precursor of autoconf.in.
10243 (autoconf.in): New target.
10245 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
10247 * doc/autoconf.texi (Limitations of Make): Mention the issue
10248 with indented comments in rules.
10250 2002-04-09 Andreas Schwab <schwab@suse.de>
10252 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
10253 ac_top_builddir when setting ac_abs_top_builddir.
10255 2002-04-06 Kevin Ryde <user42@zip.com.au>
10257 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.

10264 Reported by Ezra Peisach.

10268 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
10269 contains no literal separators.
10271 2002-04-03 Akim Demaille <akim@epita.fr>
10273 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
10274 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
10275 Use dnl, not the KILL diversion.
10276 Extracted from...
10277 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
10278 (AC_CONFIG_LINKS): here.
10279 Adjust.
10280 Don't use the KILL diversion, as it kills spurious output, which
10281 results in failures being hidden.
10282 Use m4_defn where appropriate.
10283 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
10284 after the second argument.
10285 Use m4_defn.
10286 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
10287 syntax, as it is provided by M4sugar.
10288 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
10290 2002-04-03 Andreas Schwab <schwab@suse.de>

10307 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
10309 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
10311 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.

10329 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
10330 to avoid versions of HP C which don't allow that.
10332 2002-03-27 Paul Eggert <eggert@twinsun.com>
10334 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
10335 (AS_SHELL_SANITIZE): Invoke it.
10336 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
10338 2002-03-26 Akim Demaille <akim@epita.fr>
10340 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
10342 2002-03-26 Akim Demaille <akim@epita.fr>
10344 * doc/autoconf.texi (Introduction): The GNATS base moved.
10346 2002-03-25 Paul Eggert <eggert@twinsun.com>
10348 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
10349 as POSIX requires, as it doesn't work with Zsh.
10350 * doc/autoconf.texi (Assignments): Document the problem.
10352 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
10354 * doc/autoconf.texi (Limitations of Make): Mention more issue
10355 about VPATH, overriding of macros in sub-makes, and handling of
10356 SHELL.
10358 2002-03-21 Paul Eggert <eggert@twinsun.com>
10360 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
10361 problem with here-document buffer boundaries.
10363 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
10364 when reinvoking the shell, to work around problems with installers
10365 who put strange things like "cd" commands in their environments.
10367 2002-03-19 Akim Demaille <akim@epita.fr>
10369 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
10370 From Aaron Ucko.
10372 2002-03-19 Akim Demaille <akim@epita.fr>
10374 * bin/autoscan.in (scan_file): Specify the location in `&used'
10375 invocations.
10376 From Nicolas Joly.
10378 2002-03-19 Akim Demaille <akim@epita.fr>
10380 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
10381 From Nishio Futoshi.
10383 2002-03-19 Akim Demaille <akim@epita.fr>
10385 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

10389 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
10390 (Limitations of Usual Tools): Add mkdir section.
10392 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
10393 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
10394 back on AS_DIRNAME to compute prefixes otherwise; this is
10395 roughly what mkinstalldirs does. That way, we need not have
10396 our own filename disassembler. The old disassembler did not
10397 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
10399 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
10400 Create at_test_all by a series of assignments,
10401 not by a single assignment of a long string. The latter causes ksh
10402 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
10403 presumably because of a buffer overrun.
10405 2002-03-14 Paul Eggert <eggert@twinsun.com>
10407 * lib/autotest/general.m4 (at_times_skip):
10408 Renamed from at_times. Now a boolean.
10409 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
10410 says 'times: not found'.
10412 2002-03-14 Akim Demaille <akim@epita.fr>
10414 * bin/autoreconf.in (&study_gettextize): New.
10415 (&autoreconf): Handle newest gettextize.
10416 Rerun aclocal if needed.
10417 Suggested by Andreas Schwab.
10419 2002-03-13 Akim Demaille <akim@epita.fr>
10421 * doc/autoconf.texi (Special Shell Variables): More about IFS.
10423 2002-03-13 Akim Demaille <akim@epita.fr>
10425 * doc/autoconf.texi (Header Portability): New.
10426 Add information about stdint.h and inttypes.h from Paul Eggert.
10428 2002-03-13 Akim Demaille <akim@epita.fr>
10430 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
10431 -p'.
10432 From Bob Proulx.
10434 2002-03-12 Akim Demaille <akim@epita.fr>
10436 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
10437 m4_require.
10439 2002-03-11 Andreas Schwab <schwab@suse.de>
10441 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
10442 does not do it if --with-lispdir is given.
10444 2002-03-08 Akim Demaille <akim@epita.fr>
10446 Version 2.53.
10448 2002-03-08 Akim Demaille <akim@epita.fr>
10450 * doc/autoconf.texi (Subdirectories): Clarify that the
10451 subdirectory should exist.
10453 2002-03-08 Akim Demaille <akim@epita.fr>
10455 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
10457 2002-03-08 Akim Demaille <akim@epita.fr>
10459 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
10460 aliases the actual variables, and modifications of the former
10461 affect the latter.
10463 2002-03-08 Akim Demaille <akim@epita.fr>
10465 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
10466 because of C-c: have m4 output in tmp files, then mv them.
10468 2002-03-08 Akim Demaille <akim@epita.fr>
10470 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
10471 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
10472 * bin/ifnames.in: Copyright update.

10476 * doc/autoconf.texi (Invoking autom4te): New.
10478 2002-03-05 Akim Demaille <akim@epita.fr>

10481 Kevin Ryde.
10483 2002-03-05 Akim Demaille <akim@epita.fr>
10485 Version 2.52i.
10487 2002-03-04 Akim Demaille <akim@epita.fr>
10489 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
10490 * lib/autoconf/general.m4 (AC_INIT): More informative error
10491 message for LIBOBJ.
10493 2002-03-04 Akim Demaille <akim@epita.fr>
10495 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
10496 parallel builds.
10498 2002-03-04 Akim Demaille <akim@epita.fr>
10500 * doc/autoconf.texi (Transforming Names): Equality between target
10501 and host is irrelevant.
10502 (Specifying Names, Canonicalizing): Remove all references to the
10503 backward compatibility hooks. Rather, collect them all into...
10504 (Hosts and Cross-Compilation): this new section.
10505 * doc/install.texi (System Type): Ditto.
10506 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
10507 that `--host' implies cross-compilation.
10509 2002-03-04 Akim Demaille <akim@epita.fr>
10511 * doc/autoconf.texi (Evaluation Macros): New.
10512 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
10513 useless.
10514 (_m4_foreach): Define the variant with immediate evaluation so
10515 that it contains exactly the items, not an expression which
10516 evaluation is the current item.
10517 (m4_re_string, m4_re_word): Don't over quote them.
10519 2002-03-04 Akim Demaille <akim@epita.fr>
10521 Instead of having stacking `shift's evaluated at the end, let
10522 `foreach' loops immediately evaluate them.
10524 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
10525 $*. This is the n-th time I change my mind, but hopefully this is
10526 the last...
10527 (m4_lquote): New.
10528 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
10529 efficient.
10530 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
10531 it was only a hack for m4_text_wrap.
10532 (m4_car2): Remove, replaced by...
10533 (m4_cdr): New.
10534 (_m4_foreach): Adjust.
10535 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
10536 m4_bpatsubst for clarification.

10580 Fix Autoconf PR/209.
10581 Also reported by Frank Denis.
10583 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
10585 2002-02-07 Akim Demaille <akim@epita.fr>
10587 Fix Autoconf PR/207:
10588 AC_PREFIX_PROGRAM fails with dashed program names
10590 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
10591 variable when looking for the prefix program.

10629 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

10649 2002-02-05 Akim Demaille <akim@epita.fr>
10651 * bin/autom4te.in (&parse_args): Implement `frozen files are
10652 optional are the sum of the previous files on the command line'.
10653 Also, pass `--reload-state=' on them, so...
10654 (handle_m4): don't.
10655 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
10656 (M4sh): Rely on M4sugar.
10657 (Autotest, M4sh, M4sugar): Use frozen files.
10659 2002-01-31 Akim Demaille <akim@epita.fr>
10661 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
10662 * doc/autoconf.texi (Initializing configure): Adjust.

10666 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
10667 alphanumeric to `-' instead of `_'.
10669 2002-01-30 Akim Demaille <akim@epita.fr>
10671 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
10672 for plain code, the other for cross-compilation code. The latter
10673 is now run with GCC only.
10674 * doc/autoconf.texi (Compilers and Preprocessors): New.
10676 2002-01-30 Akim Demaille <akim@epita.fr>
10678 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
10679 values.
10680 * doc/autoconf.texi (Initializing configure): Explain how to
10681 change AC_INIT default values.
10683 2002-01-29 Akim Demaille <akim@epita.fr>
10685 * tests/torture.at (Configuring subdirectories): Use configure.in,
10686 so that aclocal 1.4 works.
10687 Reported by Alexandre Duret-Lutz and Larry Schmitt.
10689 2002-01-28 Akim Demaille <akim@epita.fr>
10691 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
10692 needs an argument.
10694 2002-01-28 Akim Demaille <akim@epita.fr>
10696 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
10697 AUTOTEST_PATH *after* it was set.
10698 Don't put `.' in the PATH: the user should be precise and `./' if
10699 needed. In addition, given that the test suite does some `cd', if
10700 `.' is in the path, the `tested programs' sections will report
10701 programs found in the test suite's directory, while during the
10702 tests (performed in their own directory), these programs are no
10703 longer visible. In other words, the results is confusing and
10704 useless.
10705 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
10707 2002-01-24 Akim Demaille <akim@epita.fr>
10709 Version 2.52g.
10711 2002-01-24 Akim Demaille <akim@epita.fr>
10713 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
10714 * doc/autoconf.texi: Finally add Akim as an author.
10716 2002-01-24 Akim Demaille <akim@epita.fr>
10718 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
10719 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
10720 Bourne. Use /bin/sh.
10721 From Andreas Buening.
10723 2002-01-24 Akim Demaille <akim@epita.fr>
10725 * config/config.guess, config/config.sub, config/texinfo.tex:

10733 * config/missing.m4, config/sanity.m4, config/select.m4,
10734 * config/strip.m4: Remove, to ease sync'ing with any version of
10735 Automake.
10737 2002-01-24 Akim Demaille <akim@epita.fr>
10739 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
10740 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
10741 Reported by Geir Ove Myhr.
10743 2002-01-21 Akim Demaille <akim@epita.fr>
10745 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
10747 2002-01-21 Akim Demaille <akim@epita.fr>
10749 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
10750 message on invalid options.
10751 * bin/autom4te.in (parse_args): Don't use
10752 Autoconf::General::getopt with non valid options.
10754 2002-01-17 Jim Meyering <meyering@lucent.com>
10756 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
10757 $ac_cv_exeext so we don't use an old, invalid, cached value.
10759 2002-01-11 Akim Demaille <akim@epita.fr>
10761 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
10762 Meyering.

10770 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
10771 package.m4, since is really depends upon configure.ac, not
10772 configure.
10773 * doc/autoconf.texi (testsuite Scripts): Adjust.
10774 * tests/Makefile.am (package.m4): New.
10775 EXTRA_DIST it since its a source.
10777 2002-01-06 Akim Demaille <akim@epita.fr>
10779 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
10780 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
10781 and PACKAGE_BUGREPORT from here...
10782 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
10783 arguments.
10784 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
10785 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
10786 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
10787 * tests/tools.at (autoheader): Adjust.
10788 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
10790 2002-01-06 Akim Demaille <akim@epita.fr>

10796 * doc/autoconf.texi (Output): Improved wording regarding use of
10797 AC_OUTPUT.
10798 From Olly Betts.
10800 2001-12-18 Kevin Ryde <user42@zip.com.au>
10802 * doc/autoconf.texi (Function Portability): Add notes on sscanf
10803 sometimes needing writable input.
10805 2001-12-17 Jim Meyering <meyering@lucent.com>
10807 * doc/autoconf.texi (New Macros): Tweak wording.
10809 2001-12-14 Akim Demaille <akim@epita.fr>
10811 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
10812 trailing files, don't apply `-rf' to files which might not be
10813 created by configure (core, core.*, and *.core), but just `rm -f'.
10814 Suggested by Jonathan Kamens.
10816 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
10818 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
10820 2001-12-14 Akim Demaille <akim@epita.fr>
10822 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
10824 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
10826 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
10827 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
10828 abs_srcdir, top_srcpath to abs_top_srcdir.
10829 (_AC_OUTPUT_FILES): Adjust.
10830 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
10831 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
10832 * tests/wrappl.in, tests/wrapsh.in: Adjust.
10834 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
10836 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
10837 C/Fortran linking on HP/UX, by extracting the Fortran library
10838 search path from the LPATH line in the $F77 -v output.
10840 2001-12-12 Kevin Ryde <user42@zip.com.au>
10842 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
10843 forbidden file descriptors table.
10845 2001-11-26 Akim Demaille <akim@epita.fr>
10847 * bin/autoscan.in (%c_keywords): Build it at top level.
10848 Map to 1 in order to simplify its uses.
10850 2001-11-26 Akim Demaille <akim@epita.fr>
10852 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
10853 Remove $filepath, useless.
10854 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10855 variables, they are really part of the tokens.
10856 Split the input line on spaces and then look for tokens.
10857 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10858 because of `lex$U.$(OBJEXT)'.
10859 (&scan_files): Use "@list" instead of join.
10860 * doc/Makefile.am (CLEANFILES): Add *.fns.
10862 2001-11-26 Akim Demaille <akim@epita.fr>
10864 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
10865 Remove, replaced by...
10866 * tests/wrappl.in: Be common for all the Perl executables.
10867 In particular autoscan and autoheader want -I.
10868 * configure.ac: Adjust.
10869 * lib/autoscan/headers: errno.h is portable.
10871 2001-11-26 Akim Demaille <akim@epita.fr>
10873 * bin/autoscan.in (used): New.
10874 Use it.
10876 2001-11-26 Akim Demaille <akim@epita.fr>

10879 directives.
10880 (&scan_sh_file): Remove a duplicate pattern.
10881 (&check_configure_ac): Use long options.
10882 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
10884 2001-11-26 Akim Demaille <akim@epita.fr>
10886 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
10887 Before, having a line containing the opening of a multi line
10888 comment made the whole line be ignored.
10890 2001-11-26 Akim Demaille <akim@epita.fr>
10892 * doc/autoconf.texi (Using an Autotest Test Suite): New.
10893 (testsuite Scripts): Be one of its subsection.
10894 (Autotest Logs): New.
10896 2001-11-26 Akim Demaille <akim@epita.fr>
10898 Test groups are now run two directories deeper.
10900 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
10901 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
10902 at_top_builddir.
10903 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10904 top_srcdir, builddir and top_builddir.
10905 Use `at_*dir' relatively to the directory containing the
10906 suite, use `*dir' when relatively to the current group dir.
10908 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
10910 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
10911 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
10912 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
10913 spelling errors.
10915 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10917 * doc/autoconf.texi (Using System Type): Add an example of `case
10918 $host' usage so people quit using `case $target' everywhere.
10920 2001-11-22 Akim Demaille <akim@epita.fr>
10922 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10923 spotted by Jim Meyering.
10925 2001-11-16 Paul Eggert <eggert@twinsun.com>
10927 This patch implements a `long double' suggestion by Oliver Kiddle.
10929 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10930 static, to catch errors if the value isn't known at compile-time
10931 and the compiler supports dynamic arrays. Change its name from
10932 `_array_' to `test_array' to avoid potential name clashes.
10933 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10934 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10935 better than double. Catch a bug in GCC 2.95.2 x86.
10936 * doc/autoconf.texi (C Compiler): Document the above.
10937 * NEWS: Likewise.
10939 2001-11-13 Akim Demaille <akim@epita.fr>
10941 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10942 hand.
10943 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10945 2001-11-13 Akim Demaille <akim@epita.fr>
10947 * lib/autotest/general.m4 (AT_INIT): After having run the test
10948 group, go back to the initial directory, not to at_suite_dir.
10950 2001-11-13 Akim Demaille <akim@epita.fr>
10952 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10953 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10954 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10955 option.
10956 (AT_CHECK_CONFIGURE): Use absolute paths.
10957 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10958 The problem is still the old one: there is no means in M4 (that I
10959 know about) to create a defining macro, because there is no means
10960 to create `$1' etc., therefore, the defining macro ``swallows''
10961 all the arguments meant to the defined macro.
10963 2001-11-13 Akim Demaille <akim@epita.fr>
10965 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10966 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10967 configure.ac.
10968 * tests/aclocal.m4: Remove, as it is no longer used.
10970 2001-11-13 Akim Demaille <akim@epita.fr>
10972 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10973 variable names when referring to a single test group, or to
10974 `suite' when referring to the whole test suite.
10975 `at_last_test' is removed: m4 compute at_format itself.
10976 (at_stdout, at_stder1, at_stderr): New variables.
10977 (AT_CHECK): Use them.
10979 2001-11-13 Akim Demaille <akim@epita.fr>
10981 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10982 in PATH.
10983 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10984 Do it as soon as a test fails, don't wait till the end of the test
10985 suite.
10986 Don't remove $as_me.[0-9]*, since these files no longer exist.
10988 2001-11-13 Akim Demaille <akim@epita.fr>
10990 * tests/tools.at: Use absolute paths, since we are no longer run
10991 in place.
10993 2001-11-13 Akim Demaille <akim@epita.fr>
10995 Now that tests are running in their own private dir, there is no
10996 need to list the files to remove at the end of tests groups.
10998 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10999 (AT_data_files, at_data_files): Remove.
11000 (AT_CLEANUP, AT_DATA): Simplify.
11001 (AT_INIT): Adjust.
11002 Remove the group dir if !debug && !failed.
11003 * tests/atspecific.m4: Adjust.
11005 2001-11-13 Akim Demaille <akim@epita.fr>
11007 Start a new layout for Autotest: `testsuite' creates
11008 `testsuite.dir' in which the at-check-line etc. files are to be
11009 found, and `testsuite.dir/003' where the test group 3 is run.
11011 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
11012 at_check_line_file, at_format, at_test_normalized, at_group_dir
11013 are new variables.
11014 Create the directories.
11015 Use absolute paths for at- files.
11016 (AT_CHECK): Adjust.
11018 2001-11-11 Michael Matz <matz@kde.org>
11020 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
11021 (m4_car2): New.
11022 (m4_car): Properly quote arguments.
11024 2001-11-13 Akim Demaille <akim@epita.fr>
11026 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
11027 with stricter rules on LIBOBJS.
11029 2001-11-12 Paul Eggert <eggert@twinsun.com>
11031 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
11032 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
11033 __PROTOTYPES too.
11035 2001-11-12 Akim Demaille <akim@epita.fr>
11037 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
11039 2001-11-12 Akim Demaille <akim@epita.fr>
11041 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
11042 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
11043 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11044 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
11045 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
11046 specify to what the macro should be defined (typically to 1).
11048 2001-11-12 Akim Demaille <akim@epita.fr>
11050 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
11051 From Jim Meyering.
11053 2001-11-12 Akim Demaille <akim@epita.fr>
11055 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11056 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
11057 definition used by Automake where LEX is +/- "${missing} lex" and
11058 `missing' itself contains variables.
11060 2001-11-12 Akim Demaille <akim@epita.fr>
11062 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
11063 Now that M4sh pushes BODY, the comments were output at the end of
11064 the test suites.
11066 2001-11-08 Akim Demaille <akim@epita.fr>
11068 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
11069 that we can trace macros from aclocal.m4.
11070 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
11071 obsoleted, and redirect to the former anyway.
11072 Reported by Ralf Corsepius.
11074 2001-11-08 Akim Demaille <akim@epita.fr>
11076 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
11077 processed only if present.
11078 * tests/torture.at (Configuring subdirectories): Use autoreconf
11079 instead of successive calls to autoconf.
11080 Add a nonexistent subdirectory to exercise the patch above.
11081 Reported by Ralf Corsepius.
11083 2001-11-08 Kevin Ryde <user42@zip.com.au>
11085 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
11086 doesn't accept .S files.
11088 2001-11-07 Akim Demaille <akim@epita.fr>
11090 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
11091 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
11092 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
11093 * bin/autom4te.in (warn_forbidden): New.
11094 (handle_output): Use it.
11095 Read m4_pattern_forbid with messages.
11097 2001-11-05 Akim Demaille <akim@epita.fr>
11099 * bin/autom4te.in (--normalize): Remove.
11100 * lib/autom4te.in: Adjust.
11102 2001-11-05 Akim Demaille <akim@epita.fr>
11104 * tests/Makefile.am (testsuite): Rename this target as...
11105 ($(TESTSUITE)): this.
11106 From Nicolas Joly.
11108 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
11110 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
11111 the --prefix option, also remove it's argument.
11113 2001-11-05 Akim Demaille <akim@epita.fr>
11115 * doc/autoconf.texi (testsuite Invocation): Update.
11116 (Writing testsuite.at): Update.
11118 2001-11-03 Akim Demaille <akim@epita.fr>
11120 * doc/autoconf.texi: s/@code/@command/ where appropriate.
11122 2001-11-03 Akim Demaille <akim@epita.fr>
11124 * lib/Autom4te/General.pm: (&catfile, &canonfile)
11125 (&file_name_is_absolute): New, wrappers around routines from
11126 File::Spec.
11127 Use and export them.
11128 (&find_configure_ac): Optionally take a directory where to look at.
11129 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
11130 the arguments.
11131 Default @ARGV to `.', not find_configure_ac.
11132 (&autoreconf): Argument is a directory.

11139 (@export_forward_subs): New.
11140 Add basename, dirname, and fileparse.
11141 (@EXPORT): Adjust.
11142 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
11143 Don't look for aclocal flags if we already know aclocal is not
11144 used.
11145 Move aclocal.m4t only if it exists.
11146 Reported by Ezra Peisach.
11148 2001-11-03 Akim Demaille <akim@epita.fr>
11150 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
11151 passed on command line, defaulting to ./configure.ac if present.
11152 (&maybe_autoreconf, File::Find): Remove, unused.
11153 (&autoreconf): If autoconf is not used, don't try to trace.
11155 2001-11-02 Akim Demaille <akim@epita.fr>
11157 * configure.ac: Bump to 2.52g.
11159 2001-11-02 Akim Demaille <akim@epita.fr>
11161 Version 2.52f.
11163 2001-11-02 Akim Demaille <akim@epita.fr>
11165 * config/config.guess, config/config.sub, doc/standards.texi:
11166 * config/lispdir.m4: Update from masters.
11167 * configure.ac: Bump to 2.52f.
11169 2001-11-02 Akim Demaille <akim@epita.fr>
11171 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
11172 Don't run aclocal when aclocal.m4 is not from aclocal.
11173 From Ezra Peisach.
11174 Don't run libtoolize and gettextize if --install is not given.
11176 2001-11-01 Paul Eggert <eggert@twinsun.com>
11178 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
11179 be invoked before _AS_LINENO_PREPARE.
11180 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
11181 than character ranges.
11183 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
11184 invoking AS_BASENAME. Set the locale variables to 'C' if
11185 possible, as POSIX requires this to get the traditional
11186 behavior.
11187 * doc/autoconf.texi (Special Shell Variables): Describe the above.
11189 2001-10-31 Paul Eggert <eggert@twinsun.com>
11191 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
11192 with {}, as that triggers a bug in Bash 2.05.
11194 (_AS_LINENO_PREPARE): Use Sed rather than
11195 Awk. Fix the sed prepass to work even if there are multiple
11196 instances of $LINENO on the same line. Do not substitute for
11197 other variables like $LINENOT. Do not check file dates; such a
11198 check is unreliable on sufficiently fast machines, and removing
11199 the check makes the code simpler and more reliable. Check for
11200 output and chmod failures.
11202 * doc/autoconf.texi (Special Shell Variables): Document
11203 the above.
11205 2001-10-31 Akim Demaille <akim@epita.fr>
11207 * tests/Makefile.am (atconfig): Remove this target, Automake
11208 handles it now.
11210 2001-10-31 Akim Demaille <akim@epita.fr>
11212 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
11213 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
11214 provided, while it is optional.
11215 * configure.ac: Adjust.
11217 2001-10-26 Paul Eggert <eggert@twinsun.com>
11219 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
11220 lib/Autom4te/Struct.pm:
11221 Require Perl 5.005_03 instead of just 5.005, as some tests fail
11222 with 5.005_02.
11224 * doc/autoconf.texi (Special Shell Variables): Document some
11225 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
11227 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
11228 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
11229 eval $LINENO is not portable in practice.
11231 2001-10-24 Akim Demaille <akim@epita.fr>
11233 * lib/Autom4te/General.pm (backname): New.
11235 2001-10-24 Akim Demaille <akim@epita.fr>
11237 * m4/: Remove, merged into...
11238 * config/: here.
11240 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
11242 * doc/autoconf.texi (Shellology): Mention the problems with bash
11243 2.05's use of ANSI quoting in its `set' builtin.
11245 2001-10-22 Paul Eggert <eggert@twinsun.com>
11247 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
11248 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
11249 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
11250 POSIX decided to standardize on the int flavor of strerror_r.
11251 Always do char* test, as there's no reason not to.
11252 Assign to a char* var, to catch strerror_r that returns int*.
11254 * doc/autoconf.texi (Particular Functions):
11255 Document the above changes. Also, document the fact that
11256 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
11258 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
11260 2001-10-20 Akim Demaille <akim@epita.fr>
11262 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
11263 the executable was missing from the log.

11267 * lib/Autom4te/General.pm (&update_file): If destination is
11268 unchanged, remove the source.
11269 (&up_to_date_p): Don't be verbose, be debug.
11270 * bin/autoreconf.in: No longer support --m4dir.
11271 (&autoreconf): Display the full path of the configure.ac we are
11272 studying.
11273 Trace it only once.
11274 Be sure to honor --force with gettextize.
11275 Always run aclocal.
11276 * doc/autoconf.texi: Adjust.
11278 2001-10-20 Akim Demaille <akim@epita.fr>
11280 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
11281 Remove, dead.
11282 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
11283 `intl' is already present, as it refuses unless --force.
11284 (&parse_args): Use -I, --include instead of the old Autoconf
11285 options.
11286 ($localdir, $autoconf_dir): Remove.
11287 (@include): New.
11288 (&maybe_autoreconf): New, to preserve $_ for File::Find.
11290 2001-10-19 Jens Petersen <petersen@redhat.com>
11292 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

11298 file in @configure_input@.
11299 Don't mention `automatically' in addition to `generated'.
11300 * tests/torture.at (#define header templates): Adjust.
11302 2001-10-19 Akim Demaille <akim@epita.fr>
11304 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
11305 comment, explain how to install automatic mode selection.
11306 From Russ Allbery.
11308 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
11310 * bin/autoreconf.in (autoreconf): Display the path to the
11311 configure.ac being studied.
11313 2001-10-18 Paul Eggert <eggert@twinsun.com>
11315 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
11316 long, to work around a bug in the HP C compiler version HP92453-01
11317 B.11.11.23709.GP.
11319 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
11320 (AS_BASENAME_EXPR): New macro.
11321 (AS_BASENAME_SED): Do not assume GNU sed semantics.
11322 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
11323 and fall back on 'sed' only if the other two fail. This makes
11324 AS_BASENAME act more like AS_DIRNAME.
11325 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
11326 contains white space.
11327 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
11328 Use AS_DIRNAME, since I think it's now DOS-friendly.
11329 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
11330 Allow "dirname //FOO" to return either / or //, as POSIX allows
11331 either behavior.
11333 2001-10-10 Akim Demaille <akim@epita.fr>
11335 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
11336 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
11337 From Eric Sharkey.
11339 2001-10-10 Akim Demaille <akim@epita.fr>
11341 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
11342 m4_define, since...

11381 bother with $force since...
11382 * lib/Autom4te/General.pm: does.
11384 2001-10-08 Akim Demaille <akim@epita.fr>
11386 * bin/autoreconf.in: Rewrite in Perl.
11387 * configure.ac: Adjust.

11436 2001-10-08 Akim Demaille <akim@epita.fr>
11438 Use `add-log-current-defun-function' for ChangeLog creation.

11459 * tests/base.at: Adjust the tests to use AS_INIT.
11460 * tests/tools.at (AT_DATA_FORBIDDEN): New.

11466 * doc/autoconf.texi (config.status Invocation):

11471 empty, and if we can find a shell that does support LINENO,
11472 then set CONFIG_SHELL to that shell and then re-execute
11473 ourselves with CONFIG_SHELL.
11475 2001-10-05 Paul Eggert <eggert@twinsun.com>
11477 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
11478 doesn't exist. Remove *.tmp, as a .tmp file is created during the
11479 build of $(TESTSUITE).
11481 2001-10-05 Akim Demaille <akim@epita.fr>
11483 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

11520 compatibility with POSIX shells.

11525 instead of exec'ing to preserve $0 and $@.
11527 2001-10-01 Akim Demaille <akim@epita.fr>
11529 * tests/testsuite (AT_INIT) <at_pass_list>: New.

11548 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
11549 Don't use nested parenthesization. This patch was originally
11550 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
11551 but somehow it didn't get incorporated then.
11552 * doc/autoconf.texi (Limitations of Usual Tools):
11553 Clarify remark about sed and nested parenthesization.
11555 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
11556 Report an error if the size cannot be determined even though
11557 the type exists.
11558 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11559 Check for `expr' arithmetic overflow, and for compilation failure,
11560 and invoke a new argument $4 if either is discovered.
11561 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
11562 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
11564 2001-09-28 Akim Demaille <akim@epita.fr>

11584 status when executing the ACTION-IF-FALSE.

11604 Raja R Harinath:

11705 2001-09-22 Akim Demaille <akim@epita.fr>
11707 Rely on `$LINENO' when possible instead of `__oline__'.
11709 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
11710 `$LINENO' support replacement when not supported.
11711 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
11712 them explicitly to be sure they are not output before this section
11713 (via m4_require). Cosmetic only.

11722 character (u: -> ue) in a code comment.
11723 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
11724 it works.
11726 2001-09-21 Akim Demaille <akim@epita.fr>

11733 * lib/autoconf/programs.m4: Use extensions listed in
11734 $ac_executable_extensions when looking for programs.

11738 * lib/autoconf/general.m4: Fix a small Englisho.

11746 PATH_SEPARATOR.
11747 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

11753 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11755 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
11756 arguments. Fixed a typo.
11758 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11760 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
11761 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
11763 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11765 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
11766 * bin/autoupdate.in: Ditto.
11767 * bin/autoheader.in: Reworded a few comments.
11768 * bin/autoconf.in: Reworded help text for a few options.

11772 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11774 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
11775 already have $file). Set output files to binary mode (helps avoid
11776 CR issues on DOSish systems).
11778 2001-09-19 Akim Demaille <akim@epita.fr>
11780 * lib/autotest/general.m4: Englishoes.
11781 From Tim Van Holder and Alexey Mahotkin.
11783 2001-09-18 Paul Eggert <eggert@twinsun.com>
11785 * doc/autoconf.texi (Common Shell Constructs): New node,
11786 documenting AS_DIRNAME.
11787 (Limitations of Usual Tools): Refer to it when discussing dirname.
11788 Also, update discussion of POSIX standard to reflect latest draft.
11790 * lib/autoconf/c.m4:
11791 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
11793 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11794 Do not pass a first argument with leading '-'
11795 to expr, by parenthesizing initial integers that might be negative.
11797 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
11798 now merely checks whether it is an error to pass an argument
11799 to getpgrp.
11801 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
11802 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
11803 whether it is a (compile-time) error to pass an argument to
11804 getpgrp. This simpler test supports the revised documentation,
11805 and is all that AC_FUNC_GETPGRP's users really need.
11807 2001-09-18 Akim Demaille <akim@epita.fr>
11809 * doc/autoconf.texi (Limitations of Make) <$<>: New.
11811 2001-09-18 Akim Demaille <akim@epita.fr>

11819 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
11820 correctly.
11821 Add test for AS_BASENAME.
11822 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
11823 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11824 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11825 * tests/base.at: Fixed the expected responses. The old ones were
11826 one line out...
11827 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11828 the documentation claims it should (and how it behaved in 2.13).
11830 2001-09-18 Akim Demaille <akim@epita.fr>
11832 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
11833 the AC_CONFIG_COMMANDS invocation.
11834 This also solves the name clash problems.
11835 Don't set the package's ID.
11836 * lib/m4sugar/Makefile.am (version.m4): Revamp.
11837 No longer to be shipped.
11838 (version.in): Remove.
11839 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
11840 * lib/autoconf/status.m4: Adjust.
11841 Use `m4_PACKAGE_STRING'.
11842 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11843 the only optional argument is the name of the test suite.
11844 Expect `package.m4' to define the package signature.
11845 * lib/autom4te.in (Autotest): Add `package.m4?'.
11846 * tests/Makefile.am (package.m4): New.
11847 * tests/suite.at: ifnames is a victim.
11849 2001-09-18 Akim Demaille <akim@epita.fr>
11851 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
11852 AC_LIBSOURCE, AC_CONFIG_FILES.
11853 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
11854 program version string doesn't match the package's.
11855 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
11856 after `(cached)'.

11860 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11861 Allow expression to return any value that can fit into unsigned long
11862 (not int, as before). Check for output errors.
11864 2001-09-17 Bruno Haible <haible@ilog.fr>
11866 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11867 Always include <stdio.h> and <stdlib.h>. Evaluate
11868 the expression in an extra function before these includes. Call
11869 fprintf "%d" only after ensuring the argument is of type 'int'.
11870 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11872 2001-09-17 Paul Eggert <eggert@twinsun.com>
11874 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11875 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11876 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11877 when they don't exist.
11879 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11880 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11881 need it.
11883 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11884 version with the version used by fileutils 4.1, except use
11885 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
11886 we don't need it.
11888 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
11890 2001-09-13 Akim Demaille <akim@epita.fr>
11892 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
11893 _first_.
11894 Reported by Gerrit P. Haase.

11898 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

11914 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
11915 Likewise.

11930 * lib/autotest/general.m4 (AT_INIT): Create and remove
11931 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
11932 test suites can cohabit.
11934 2001-09-13 Akim Demaille <akim@epita.fr>
11936 * tests/mktests.sh: Don't output banners for empty test files.
11938 2001-09-13 Akim Demaille <akim@epita.fr>

11986 2001-09-10 Akim Demaille <akim@epita.fr>
11988 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

12004 2001-09-07 Akim Demaille <akim@epita.fr>
12006 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
12007 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
12008 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
12009 related variables into `at_package_*'.

12034 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'

12036 From Uwe Seimet.
12038 2001-09-05 Akim Demaille <akim@epita.fr>
12040 * bin/autom4te.in: --language is -l, not -s.
12042 2001-09-05 Akim Demaille <akim@epita.fr>
12044 Be ready to handle filenames as stupid as `dnl.at', for if even
12045 the maintainer is dumb enough to do that...
12047 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
12048 excellence in M4 quotation: consider `__file__' is active.
12050 And BTW, when invoking m4, pass the --include in the right order:
12051 the wrong one.
12053 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
12054 4m.
12056 2001-09-05 Akim Demaille <akim@epita.fr>
12058 * lib/Autom4te/XFile.pm: New lib file.
12059 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
12060 * bin/autoheader.in: Use it.
12062 2001-09-05 Akim Demaille <akim@epita.fr>
12064 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff

12072 * bin/autoscan.in: Use `getopt' and `find_files' etc.
12073 Add -I, --include support.
12074 * doc/autoconf.texi (autoscan Invocation): Adjust.
12076 2001-09-05 Akim Demaille <akim@epita.fr>
12078 CVS GNU M4 doesn't like `undefine(undefined)'.
12080 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
12081 New, extracted from main.
12082 Use IO::File wherever possible.
12083 (input.m4): Be constant, use -I instead of hard coding $tmp.
12084 Therefore be a quoted heredoc.
12085 Don't invoke `_au_disable', since ac was not loaded, but just
12086 `unm4.m4'.
12088 2001-08-31 Akim Demaille <akim@epita.fr>
12090 Version 2.52d.
12092 2001-08-31 Akim Demaille <akim@epita.fr>
12094 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the
12095 previous patch.
12096 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Can create `config.hin~'.
12098 2001-08-31 Akim Demaille <akim@epita.fr>
12100 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
12101 serious problems handling heredocs in heredocs.
12102 Reported by Nicolas Joly.
12104 2001-08-31 Akim Demaille <akim@epita.fr>
12106 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
12107 (Making testsuite Scripts): Update.
12109 2001-08-31 Akim Demaille <akim@epita.fr>
12111 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
12113 2001-08-31 Akim Demaille <akim@epita.fr>
12115 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
12116 (testsuite Scripts): There is no such thing as `atconfig.in'.
12117 And actually one diagram is missing: test suite runtime.
12119 2001-08-31 Akim Demaille <akim@epita.fr>
12121 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
12122 inverse order.
12124 2001-08-31 Akim Demaille <akim@epita.fr>
12126 * bin/autoupdate.in (@include): `installcheck' revealed the path
12127 to m4sugar was lacking!
12129 2001-08-31 Akim Demaille <akim@epita.fr>
12131 * man/Makefile.am (.x.1): We really have to pass
12132 autom4te_perllibdir.
12134 2001-08-31 Akim Demaille <akim@epita.fr>
12136 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
12137 debug scripts, in particular passing explicitly listed tests to
12138 run is stupid.
12140 2001-08-31 Akim Demaille <akim@epita.fr>
12142 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
12143 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
12144 Use directly autom4te, not autoconf.
12145 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
12147 2001-08-31 Akim Demaille <akim@epita.fr>
12149 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
12150 * bin/autoheader.in (%symbol): Strip arguments of macros.

12156 2001-08-31 Akim Demaille <akim@epita.fr>
12158 * bin/autom4te.in (&parse_args): Die on unknown languages.
12159 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
12160 need for autoconf.
12161 Promote --include over --macrodir and other obsolete options.
12163 2001-08-31 Akim Demaille <akim@epita.fr>
12165 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
12166 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
12167 * bin/autom4te.in ($autoconf): Pass --force.
12168 `print $out' doesn't print `$_' but `$out'.
12169 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
12170 (autoheader): Pass --force since the test suite goes too fast for
12171 the time stamps.
12172 Adjust to the new autoheader messages.
12174 2001-08-31 Akim Demaille <akim@epita.fr>
12176 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
12177 Check the completeness of the #template.
12178 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
12179 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
12180 invocation.
12182 2001-08-31 Akim Demaille <akim@epita.fr>
12184 * lib/Autom4te/General.pm (&find_file, &update_file): New.
12185 * bin/autoupdate.in, bin/autoheader.in: Adjust.
12186 Drop AC_MACRODIR dead for real.
12187 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
12188 `autoheader: `config.hin' is created'.
12189 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
12191 2001-08-31 Akim Demaille <akim@epita.fr>
12193 * bin/autoheader.in: Rewrite in Perl.
12194 * tests/autoheader: Adjust.
12196 2001-08-31 Akim Demaille <akim@epita.fr>
12198 * bin/autoconf.in (--include, -I): New option.
12199 Map --localdir, --autoconf-dir onto it.
12200 Forward autom4te's options instead of interpreting them.
12201 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
12202 There is no such envvar since the inception of autom4te.cfg.
12203 * bin/autom4te.in (&parse_args): Uniquify `@include'.
12204 * bin/autoupdate.in: Adjust, and perform more control.
12205 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
12206 * tests/autoconf: Dittowise.
12208 2001-08-31 Akim Demaille <akim@epita.fr>
12210 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
12211 * bin/autom4te.in (&find_file): Support `FILE?' standing for
12212 optionally `FILE'.
12213 Use -e, not -f, since /dev/null for instance is OK.
12214 (&parse_args): Adjust.
12215 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
12217 2001-08-31 Akim Demaille <akim@epita.fr>
12219 * configure.ac: Also find tested executables in bin.
12220 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
12221 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
12222 installed peer executables, only PATH is allowed to resolve it.
12223 Pass `autoconf_dir' via options, not via invisible envvars.
12224 * lib/Autom4te/General.pm (&find_peer): Remove.
12225 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
12226 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
12227 * man/Makefile.am: Let help2man rely on PATH instead of trying to
12228 find the executables for it.
12229 * tests/Makefile.am: Major cleanup. Too lazy to document...
12230 * tests/atlocal.in: Remove all the obscure envvar manipulations.
12231 We only need PERL.
12232 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
12233 indeed related to running the test suite, while passing
12234 --autoconf-dir and others is related to running non installed
12235 Autoconf executables. So don't do that, leave it to...
12236 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
12237 * tests/autoscan: New.
12238 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
12239 refer to library files: rely on --language.
12241 2001-08-29 Akim Demaille <akim@epita.fr>
12243 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
12244 s/--set/--language/.
12246 2001-08-29 Akim Demaille <akim@epita.fr>
12248 * doc/autoconf.texi: Strip the @nodes.
12249 Suggested by Paul Eggert.
12250 (Initializing configure): Typo.
12252 2001-08-29 Akim Demaille <akim@epita.fr>
12254 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
12255 Suggested by Paul Eggert.
12257 2001-08-29 Akim Demaille <akim@epita.fr>
12259 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
12260 download in a tmp dir.
12262 2001-08-29 Akim Demaille <akim@epita.fr>
12264 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
12265 case insensitive OSes out there :(
12266 From Tim Van Holder.
12268 2001-08-29 Akim Demaille <akim@epita.fr>
12270 * lib/autom4te.in: New.
12271 * lib/Makefile.am (edit, autom4te.cfg): New.
12272 * bin/autom4te.in (BEGIN): Simplify.
12273 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
12274 (&load_configuration): New. Use it.
12275 (&parse_args): Support --mode, --set, and --melt.
12276 * bin/autoconf.in: Simplify and adjust.
12277 * tests/Makefile.am (AUTOMAKE): Use --set.
12278 * tests/atlocal.in: Adjust.
12279 * BUGS: distcheck and check are weak.
12281 2001-08-29 Akim Demaille <akim@epita.fr>
12283 * lib/autotest/general.m4: Use
12284 foo=`(command) 2>/dev/null`
12285 not
12286 foo=`command` 2>/dev/null
12287 (at-devnull): Rename as...
12288 (AT-devnull): this.
12289 (--clean): Remove AT-* files too.
12290 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
12291 Reported by Nicolas Joly.
12293 2001-08-28 Akim Demaille <akim@epita.fr>
12295 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
12296 quotes inside single quotes.
12297 Reported by Nicolas Joly.
12299 2001-08-28 Kevin Ryde <user42@zip.com.au>
12301 * doc/autoconf.texi (Function Portability): Mention C right shifts.
12303 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
12305 * lib/autotest/general.m4: Reword some messages.
12306 (AT_INIT): Check for the `times' builtin before using it.
12307 Support test ranges as arguments to the testsuite.
12308 Have -e imply -d as the help text suggested.
12310 2001-08-27 Akim Demaille <akim@epita.fr>
12312 * Makefile.maint: Formatting changes.
12313 (do-po-update, po-update, cvs-update, update): New targets.
12314 (AMTAR): Remove.
12316 2001-08-27 Akim Demaille <akim@epita.fr>
12318 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

12321 <AUTOTEST_PATH>: May contain absolute dir names.
12323 2001-08-27 Akim Demaille <akim@epita.fr>
12325 * lib/autotest/general.m4 (AT_INIT): Log the command line.
12326 Support `VAR=VAL' as arguments.
12327 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
12328 may be set via the command line.
12330 2001-08-27 Akim Demaille <akim@epita.fr>
12332 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
12333 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
12334 first the build dirs, then the src dirs.
12335 * configure.ac (AC_CONFIG_TESTDIR): Adjust.
12337 2001-08-27 Akim Demaille <akim@epita.fr>
12339 * lib/autotest/general.m4 (AT_INIT): Output the definition of
12340 at_data_files earlier.
12341 (--clean, -c): New option.
12342 * tests/Makefile.am: Use this option.
12344 2001-08-27 Akim Demaille <akim@epita.fr>
12346 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
12347 `ac_top_builddir' to mimic Automake's vocabulary, which much more
12348 readable.
12349 Adjust callers.
12350 * doc/autoconf.texi (Configuration Actions): Document the vars
12351 available in commands.
12352 Emphasize the risks of collisions in init-cmds.

12356 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
12357 (Initializing configure): this new node.
12359 2001-08-27 Akim Demaille <akim@epita.fr>

12372 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move
12373 to...
12374 * lib/autoconf/autoheader.m4: this new file.
12375 * lib/autoconf/general.m4 (AH_OUTPUT, AH_VERBATIM)

12382 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
12383 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
12384 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
12385 -> ac_dir).
12386 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
12387 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
12389 2001-08-27 Akim Demaille <akim@epita.fr>
12391 * lib/autoconf/autoconf.m4 (AC_CONFIG_COMMANDS)

12414 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
12415 (AMTAR): Help automake define it.
12416 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
12417 needed, 1.5 can have a macro and a target with the same name.
12418 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
12419 * m4/strip.m4: New.

12432 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
12433 Adjust callers.
12434 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
12435 the name of the directory they're in, instead of the filename,
12436 since version.m4 is now in m4sugar, but m4_acversion must not be
12437 classified as an Autoconf macro.
12438 ($input_m4): Don't qualify the path to m4sugar.
12439 Rather, pass autoconf_dir to m4.
12440 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
12441 * tests/suite.at: Require 2.52c.
12443 2001-08-27 Akim Demaille <akim@epita.fr>

12455 of config.log on traps.
12456 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
12457 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
12458 for config.status'.
12459 Open the log as soon as possible.
12460 Use the same log introduction as configure's.
12462 2001-08-22 Paul Eggert <eggert@twinsun.com>
12464 * doc/autoconf.texi (Indices): New node.
12465 Move indices out of the top level menu and into this submenu.
12467 2001-08-22 Akim Demaille <akim@epita.fr>
12469 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
12470 AC_TRY_COMMAND.
12471 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.
12473 2001-08-22 Akim Demaille <akim@epita.fr>

12524 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
12525 * NEWS, README, README-alpha, TODO, tests/README: This package is
12526 `Autoconf', not `autoconf' (the executable).
12528 2001-08-20 Akim Demaille <akim@epita.fr>
12530 Info readers seem to need `Index' in the index node title :(
12532 * doc/autoconf.texi: Reverse the 2001-08-15 change which
12533 simplified index node names.
12535 2001-08-20 Akim Demaille <akim@epita.fr>

12577 2001-08-20 Akim Demaille <akim@epita.fr>
12579 Huh!?!?! There are still some user EOF tags used, which prevents
12580 their use in AC_CONFIG_COMMANDS for instance...
12582 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
12583 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

12646 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
12647 `$0.log' as for projects where testsuite is in src, we'd have
12648 testsuite.log created in src.

12662 2001-08-17 Akim Demaille <akim@epita.fr>
12664 * doc/autoconf.texi: Work around Texinfo buglets.
12665 (Transformation Rules): One example is enough, users are expected
12666 to have their brains on. And BTW, use DESTDIR.
12667 (dvar): New macro. Use it.
12669 2001-08-17 Akim Demaille <akim@epita.fr>
12671 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

12677 * bin/autom4te.in: --normalize is a new option.
12678 * bin/autoconf.in: Use it.

12704 * doc/install.texi: Use @command.

12711 value.
12712 From Kevin Ryde.
12714 2001-08-15 Akim Demaille <akim@epita.fr>
12716 * Makefile.maint (CVS): New.
12717 (local-check): Run changelog-check. last.
12718 (alpha): Don't depend upon local-check, since...
12719 (cvs-dist): depends upon it.
12721 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
12723 * tests/Makefile.am: Use a clean-local rule to remove
12724 autom4te.cache (it's a directory, not a file.
12725 * Makefile.am: Ditto (but maintainer-clean-local).
12727 2001-08-15 Akim Demaille <akim@epita.fr>
12729 * bin/autom4te.in (@m4_warning): New.
12730 (&handle_m4): Use it.
12731 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
12732 warnings are issued at each run.
12733 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
12734 is in the src tree.
12736 2001-08-15 Akim Demaille <akim@epita.fr>
12738 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
12739 don't waste time running `autoupdate --version' works.
12740 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
12742 2001-08-13 Akim Demaille <akim@epita.fr>
12744 * doc/autoconf.texi (ma): Rename this index as...

12758 duration of the test suite.
12760 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>

12763 endianness for comparison instead of relying on AT_CHECK_ENV.
12765 2001-08-11 Paul Eggert <eggert@twinsun.com>
12767 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
12768 to the INSTALL file.
12770 2001-08-11 Paul Eggert <eggert@twinsun.com>

12797 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
12799 * tests/semantics.at (AC_C_BIGENDIAN): New test.
12801 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12803 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
12804 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
12805 * doc/autoconf.texi (C Compiler Characteristics): Update
12806 documentation for AC_C_BIGENDIAN.
12808 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12810 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
12811 magic values from an object file when cross-compiling.
12812 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12814 2001-08-10 Akim Demaille <akim@epita.fr>
12816 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12817 effects.
12818 Suggested by Russ Allbery.
12820 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12822 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12823 current $prefix to the sub-configures.
12825 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12827 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12828 extension (needed on BeOS). Reported by Guido van Rossum.
12830 2001-08-09 Akim Demaille <akim@epita.fr>
12832 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12834 2001-08-07 Akim Demaille <akim@epita.fr>
12836 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12837 removed.
12838 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12839 No need to remove the files before and after the each test, before
12840 each test and at the end of the suite is enough.
12841 Display only the children `times', not the shell's.
12842 If the test failed or was skipped, at-times is not available.
12844 2001-08-07 Akim Demaille <akim@epita.fr>
12846 Always produce testsuite.log, including when there are no
12847 failures. This helps getting information on skipped tests, and
12848 duration of the tests. Err, implement the latter btw.
12850 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12851 Dump information on the first run of each test.
12852 (AT_CLEANUP): Create `at-times' containing the duration of the
12853 test group.
12855 2001-08-07 Akim Demaille <akim@epita.fr>
12857 The use of `dumpstat' revealed that `len' was used although it
12858 should not. m4_text_wrap was using it, but in the Autoconf world
12859 where it is legal. Hence (i) test M4sh in its own world, not
12860 Autoconf's, and (ii), ahem, fix the bug :)
12862 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12863 does not like `' instead of [].
12864 (AT_INIT): Forbid `^_?AT_'.
12865 And don't output such tokens.
12866 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12867 `script.as', and `autom4te.cache'.
12868 Remove `empty' and `macro' which are no longer used.
12869 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12870 * tests/m4sugar.at: Use it.
12871 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
12873 2001-08-07 Akim Demaille <akim@epita.fr>
12875 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
12877 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
12879 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
12881 2001-08-04 Akim Demaille <akim@epita.fr>
12883 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
12884 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
12885 AC_TRY_LINK.
12886 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
12887 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
12888 (AC_F77_MAIN): Likewise.
12890 2001-08-04 Akim Demaille <akim@epita.fr>
12892 Don't rely on M4sugar outputting the patterns in files, since we
12893 might process the output _without_ running m4, hence without these
12894 files.
12896 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12897 * bin/autom4te.in (@Request::includes): Remove, unused.
12898 (@Request::source): Rename as...
12899 (@Request::input): this.
12900 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
12901 (&handle_output): Fetch the patterns from the traces.
12902 `$forbidden' and `$allowed' are constant: use m//o.
12903 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
12904 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
12906 2001-08-04 Akim Demaille <akim@epita.fr>
12908 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
12909 autoconf', i.e., in addition to caching traces, cache the output.
12911 * bin/autom4te.in (Request::cache): Rename as...
12912 (Request::id): this.
12913 ($cache, $icache, $tcache, $ocache): New.
12914 (&handle_m4): Save M4 output in the cache instead of $tmp.
12915 (&handle_output): Adjust.
12916 (&up_to_date_p): Check that the output cache is up to date too.
12917 (top level): Run `&handle_m4' iff force or the cache is invalid.
12918 Run `&handle_output' if the output cache is more recent.
12920 2001-08-04 Akim Demaille <akim@epita.fr>
12922 * bin/autom4te.in ($force): New.
12923 (&parse_args, &print_usage): -f, --force is a new option.
