711 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
713 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
714 early on the reader side, drop stderr of the input to avoid
715 `broken pipe' error output; this may happen even with shell
716 builtin `echo' of some bash versions. Reports by Ian Macdonald
717 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
719 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
721 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

731 Fix some wording problems noted by Paolo Bonzini in:
732 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
733 * doc/autoconf.texi (Signed Overflow Examples): Give more
734 discussion about the allow_superuser_privileges example,
735 and change it a bit to make things clearer.
736 (Optimization and Wraparound): Clarify whether the compiler
737 will generate an infinite loop for the example derived from
738 Autoconf's mktime test.
739 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
740 Also, clarify unsigned multiplication overflow.
742 2007-01-04 Eric Blake <ebb9@byu.net>
744 * bin/Makefile.am (RELEASE_YEAR): New macro.
745 (edit): Use it to supply correct copyright year to scripts.
746 * bin/autoconf.as (version): Use it.
747 * bin/autoheader.in ($version): Likewise.
748 * bin/autom4te.in ($version): Likewise.
749 * bin/autoreconf.in ($version): Likewise.
750 * bin/autoscan.in ($version): Likewise.

754 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
756 * doc/autoconf.texi (Integer Overflow): Revised based on today's
757 feedback. The most important changes document what happens when
758 you convert an out-of-range value to a signed integer type, and
759 say that (sum < a) != (b < 0) reliably detects overflow when sum =
762 * doc/autoconf.texi (Integer Overflow): Greatly expand and
763 rewrite, taking notions from the recent discussion on the gcc and
764 autoconf mailing lists; please see
765 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
766 and follow the many links.
767 (Integer Overflow Basics, Signed Overflow Examples):
768 (Optimization and Wraparound, Signed Overflow Advice):
769 (Signed Integer Division): New sections.
771 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
773 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
774 preprocessor macro arguments in traced name.
775 * doc/autoconf.texi (Defining symbols): Document longstanding
776 support for AC_DEFINE-ing macros with arguments, and document
777 behavior when the same variable has multiple AC_DEFINEs.
778 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
779 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
780 macros directly, giving much shorter and simpler code.
782 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
784 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
785 space before "$ac_configure_args" to prevent a 'config.status
786 --recheck' failure if ac_configure_args doesn't contain a leading
787 space. This works around a problem with the XEmacs configure.ac,
788 which uses the (undocumented) ac_configure_args variable
789 inconsistently with Autoconf.
791 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
793 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
794 Include <limits.h>, and use its INT_MAX to rewrite the
795 j loop so that it does not overflow 'int'. Problem reported by
797 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
798 Play it safe by shifting left by 1 rather than multiplying by 2,
799 as GCC is less likely to optimize this away when the value
800 is signed (when it assumes overflow leads to undefined behavior).
801 Also, don't assume time_t uses two's complement.
803 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
805 * tests/torture.at (Substitute a 2000-byte string): Avoid using
806 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
807 dumps core on it. Report by Tim Rice.
809 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
811 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
812 --disable-option-checking to --help output even when
813 AC_PRESERVE_HELP_ORDER is not used.
814 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
815 --with argument, rather than argument with [-.] replaced by
817 * NEWS: Fix typo in previous change; the news was in the
820 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
822 * NEWS: Warnings are now generated by default for unknown
823 --enable-* and --with-* options.
824 * doc/autoconf.texi (Option Checking): Renamed from
825 (Configure Option Checking). Tighten up the wording a bit.
826 (External Software, Package Options): Cross-reference to Option
827 Checking, and use this to shorten our section.
828 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
829 "$x" to test "x$foo" != x.
830 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
831 Don't warn if $enable_option_checking is "no".
832 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
833 ac_unrecognized_opts to the empty string.
834 Don't echo the unrecognized opts, as this might mishandle
835 backslashes or leading -.
836 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
837 usage next to the other --disable-FEATURE options in the
840 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
842 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
843 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
844 Print warning for unrecognized --with and --enable options
845 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
846 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
847 Disable option checking when subdirs are configured.
848 (AC_OUTPUT): If warnings are enabled, print warning about
849 unrecognized --with and --enable options at the end of
850 the configure output (as well as at the beginning).
851 * doc/autoconf.texi (Option Checking): New node.
852 Document new option warning functionality.
854 2006-12-16 Eric Blake <ebb9@byu.net>
856 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
857 * NEWS: Start news for current version.
859 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
861 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
862 Define HAVE_GETMNTENT to 1, not to the empty string.
863 Problem originally reported by Jochen Friedrich in
864 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
866 This change prompted by a problem report by Andrey Simonenko in
867 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
868 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
869 object-like macros only, in the traditional portable character
871 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
872 Warn about attempts to define things that are not identifiers.
873 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
874 awful hack that AC_DEFINEd macro names containing parentheses.
876 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
878 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
879 too drastic, even if Texinfo in theory requires it for info mode.
881 (config.status Invocation): Renamed back from Recreating a
883 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
884 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
886 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
888 * NEWS: Version 2.61a.
890 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
891 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
893 * NEWS: Document changes with echo and printf, and the lack
894 of limits on the total size of multi-line values of substituted
895 variables, and the AC_FUNC_FSEEKO fix.
897 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
899 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
900 Writing configure.ac.
901 (Autoconf Input Layout): Renamed from configure.ac Layout.
902 (Recreating a Configuration): Renamed from config.status Invocation.
903 (Obsolete Recreation): Renamed from Obsolete config.status Use.
904 (acconfig Header): Renamed from acconfig.h.
905 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
906 (Writing Testsuites): Renamed from Writing testsuite.at.
907 (Autom4te Cache): Renamed from autom4te.cache.
909 * BUGS: Remove mention of VPATH problem, since it's now documented
910 not to be a bug in the Autoconf build procedure itself, but rather
911 a problem with the proprietary `make' programs.
913 * doc/autoconf.texi (Build Directories): Add a cross reference
916 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
917 * doc/standards.texi: Sync from gnulib.
919 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
920 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
921 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
922 generated automatically.
924 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
926 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
927 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
928 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
930 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
932 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
933 `CEOF$ac_eof' special marker, the awk script cannot contain a
934 line matching `^CEOF', so this is not needed any more.
935 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
936 special marker in the test.
938 2006-12-06 Stepan Kasal <kasal@ucw.cz>
940 * tests/tools.at (autom4te preselections): Use `find -newer';
941 remove one of the sleeps.
943 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
944 more readable, using ...
945 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
947 * doc/autoconf.texi (autoheader Invocation): Do not double-
948 quote the parameter of `AH_BOTTOM' in the example.
950 2006-12-05 Stepan Kasal <kasal@ucw.cz>
952 * doc/autoconf.texi (Configuration Headers): Remove the
953 example with multiple input files.
954 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
955 multiple input files.
957 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
959 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
960 creating the awk substitution script, handle one input line at a
961 time, so that the maximum length of a substituted (multi-line)
962 value is not limited by the size of the sed pattern space.
963 The trade-off is a slightly repetitive sed script.
964 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
965 can only have up to 7 characters, due to Solaris 10 /bin/sed.
966 * tests/torture.at (Substitute a 2000-byte string): Increase the
967 test with several long lines, they should not be caught by sed
970 * tests/tools.at (autom4te preselections): New test, to flag
971 entries missing from autom4te.cfg.
972 Report by David Byron <dbyron@hheld.com>.
974 * tests/torture.at (Substitute a 2000-byte string): Actually use
975 AC_PROG_AWK, so the last change works as intended.
976 (Substitute and define special characters): Likewise.
977 (Substitute a newline): Likewise.
979 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
980 instead of `awk' consistently.
981 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
982 * tests/torture.at (Torturing config.status): Test both the
983 result of AC_PROG_AWK and plain awk.
984 (Substitute a 2000-byte string): Likewise.
985 (Substitute and define special characters): Likewise.
986 (Substitute a newline): Likewise.
988 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
990 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
991 can be assigned to a function pointer. Problem reported by
992 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
993 part of a patch by Ralf Wildenhues in that same bug report.
995 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
997 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
998 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
1000 2006-12-01 Eric Blake <ebb9@byu.net>
1002 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
1003 cross-compiling from cygwin to mingw.
1004 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
1005 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
1006 to lib/autoconf/c.m4.
1008 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1010 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
1011 string for more reliable failure. Wrap the entire test that
1012 causes the broken Solaris printf to dump core, in a subshell,
1013 so the segmentation fault message is reliably suppressed.
1014 Fix shell expansion errors by using /usr/ucb/echo always;
1015 avoid an error on systems without it by another subshell.
1016 Avoid m4 expansion of `$1'. Set the zeroth argument of the
1017 subshell-$as_echo to `as_echo', for better error message.
1019 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1021 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
1022 `BASH_SOURCE' contain a newline, set them to empty, as they may
1025 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
1027 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
1028 years and is too hard to maintain now. The last straw was
1029 reported by Jerker Baeck in
1030 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
1031 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
1032 * doc/autoconf.texi (Particular Functions): Move
1033 AC_FUNC_SETVBUF_REVERSED from here...
1034 (Obsolete Macros): ... to here. Say that it does nothing now.
1035 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
1036 Turn into (almost) a no-op.
1038 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
1040 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
1041 These macros are obsolescent and new applications shouldn't need them.
1042 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
1043 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
1044 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
1045 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
1046 (AC_FUNC_VPRINTF): Likewise.
1047 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
1048 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
1049 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
1051 * doc/autoconf.texi (Setting Output Variables): Mention that
1052 @VAR1@VAR2 has unspecified behavior. Problem reported by
1054 * NEWS: Mention this.
1056 * Makefile.am: Put only a single '#' into the copyright notice,
1057 so that it's also present in the output file. Standardize wording
1058 in makefile copyright notices to match GNU coding standards.
1059 * bin/Makefile.am: Likewise.

1072 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1074 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
1075 in the sed script that mangles the awk script: delete up to the
1076 first exclamation mark only.
1077 * tests/torture.at (Substitute and define special characters):
1080 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1082 Rewrite config files generation: avoid quadratic growth in
1083 the number of substituted variables by using awk instead of sed
1084 for the bulk of the substitutions.
1085 * NEWS: Mention this.
1086 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
1087 forbidden in the output (and thus input) file.
1088 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
1089 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
1090 generate just one large awk script for substitutions,
1091 eliminating much of the earlier complexity, while adding some
1092 new complexity. Only expand the substitution templates at
1093 configure time, for smaller configure script size. If
1094 _AC_SUBST_FILES are used, test 'awk' for working getline support
1095 at config.status time. If absent, interpolate through the
1096 shell. The awk script was written with much help
1097 from Paolo Bonzini and Paul Eggert.
1098 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
1099 (_AC_SED_FRAG_NUM): Likewise.
1100 (_AC_SUBST_CMDS): Renamed from...
1101 (_AC_SED_CMDS): ...this.
1102 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
1103 * tests/torture.at (Substitute a 2000-byte string): Also
1104 substitute a line with 1000 words, and a variable with several
1106 (Substitute and define special characters): Test awk special
1107 characters, and put substitution input strings `@foo@' in the
1108 output, to test that no recursion happens; test several other
1109 combinations from Paolo Bonzini.
1111 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
1113 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
1114 that replaced echo with AS_ECHO where this wasn't necessary.
1115 Problem reportd by Ralf Wildenhues.
1116 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
1117 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
1118 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
1120 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1122 * lib/freeze.mk (GREP): Removed, no need to initialize this.
1124 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
1126 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
1127 that traditional Awk lacks 3-arg "split". It has it.
1128 Mention that FS must be a single character, and a few other
1129 99-byte limits of traditional Awk.
1130 Mention that if (i in a) doesn't work with traditional Awk.
1132 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
1134 * tests/autotest.at (BSx641-newline in command):

1136 (Newline-CODE-BS-newline in command):
1137 (Single-quote-BS-newline in command):
1138 (Single-quote-newline-BS-newline in command):
1139 Use printf '%s\n' instead of echo, for portability to hosts
1140 where echo interprets backslashes. This will break on hosts
1141 that lack printf, but for now let's assume all such hosts
1142 are dead (if not, we should get reports of test failures).
1144 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
1146 'echo' has some portability problems, when given a first argument
1147 with a leading '-', or when given any argument containing '\'.
1148 Avoid using 'echo' in these cases.
1149 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

1152 * lib/autotest/general.m4 (AT_INIT): Likewise.
1153 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
1154 argument might be unportable.

1173 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
1174 * bin/autoconf.as: Redo verbose flag implementation, as the old
1175 scheme wouldn't work with AS_ECHO.
1176 * lib/autotest/general.m4 (AT_INIT): Likewise.
1177 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
1178 Don't use ECHO_T, since ECHO_N is now reliable.
1179 * lib/autotest/general.m4 (AT_INIT): Likewise.
1180 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
1181 rather than using a here-document to put the script into a file.
1182 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
1184 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
1185 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
1186 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
1187 bug, but we might as well stop using ECHO_N and ECHO_C internally.
1188 * lib/autotest/general.m4 (AT_SETUP): Likewise.
1189 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
1190 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1191 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
1192 operand, as AS_ECHO requires. Avoid double file name expansion.
1193 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
1194 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
1195 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
1196 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
1197 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
1198 Double-quote strings that would otherwise contain M4 comments.
1199 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
1201 * configure.ac (AC_INIT): Bump to 2.61a.
1204 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
1208 * configure.ac (AC_INIT): Bump to 2.61.
1211 * tests/autotest.at (Macro with backslash in a test title):
1212 Comment out for now, as this tests neither fails nor passes
1213 reliably. Problem reported by Ralf Wildenhues.
1215 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
1217 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
1218 in previous change, which caused test failures.

1222 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
1223 code for --enable, --disable, --with, and --without to...

1300 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
1303 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
1305 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
1306 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
1307 Imported from a similar patch to gnulib by Bruno Haible.
1309 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
1311 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

1328 and Stepan Kasal <kasal@ucw.cz>
1330 Handle special characters in test case titles correctly.
1331 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
1333 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
1334 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
1335 argument. Extend to check titles printed by ./micro-suite and
1336 ./micro-suite -l and the title in micro-suite.log.
1337 (Backquote in a test title,
1338 Single-quote in a test title,
1339 Double-quote in a test title): Don't expect failure anymore.
1340 (Backslash in a test title): Put a non-whitespace character after the
1341 backslash so that Bourne shells might actually see it as an escape
1343 (Brackets in a test title,
1344 Pound in a test title,
1345 Comma in a test title,
1346 Quoted Macro in a test title,
1347 Macro in a test title,

1350 Macro with double-quote in a test title,
1351 Macro with backslash in a test title): New tests expected to fail.
1352 * tests/torture.at (#define header templates): M4-quote this title in
1353 AT_SETUP call so that no M4 code is commented inadvertently somewhere.

1361 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
1363 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
1364 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
1365 5363) simply issues a warning when dividing by zero at compile
1366 time. Problem reported by Elias Pipping.
1368 2006-10-26 Eric Blake <ebb9@byu.net>
1371 * doc/autoconf.texi (Evaluation Macros): Improve the example to
1372 show effect on macros that expand with commas.

1397 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
1399 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1400 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
1401 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
1402 reported by Nelson H. F. Beebe for Coreutils 6.4.
1404 * tests/tools.at (autoconf --trace: user macros): Remove test
1405 for tracing multiline macros, since m4 1.4.7a uses a different
1406 way to number lines. Problem reported by Ralf Wildenhues.
1408 2006-10-24 Stepan Kasal <kasal@ucw.cz>
1410 * bin/autom4te.in (handle_m4): Do not redirect stdin to
1411 /dev/null since the heuristics for interactive behaviour was

1482 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1484 (Imported from Automake.)
1485 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
1486 which incorrectly sets the mode of an existing destination
1487 directory. In some cases the unpatched install-sh could do the
1488 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
1489 system. We hope this is rare in practice, but it's clearly worth
1490 fixing. Problem reported by Alex Unleashed in
1491 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
1492 Also, don't bother to check for -m bugs unless we're using -m;
1493 suggested by Stepan Kasal.

1567 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
1569 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
1570 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
1571 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
1572 Use a better substitute, by inspecting the output of "ls"
1573 rather than just using ":".
1574 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
1575 rather than AS_EXECUTABLE_P, since we needn't worry about
1576 non-regular files here.
1578 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
1579 due to configuration hassles with this. See Tonya Underwood's report
1580 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

1604 comment about ac_cpp_err; it was incorrect, and anyway
1605 ac_cpp_err is being removed below.
1606 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
1607 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
1608 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
1610 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
1611 with werror_flag and conftest.err and so forth. This is more
1612 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
1613 and anyway the user shouldn't normally want to see this gorp logged.
1614 Problem reported by Ralf Wildenhues.
1615 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
1616 empty, not 'no', since the rest of the code uses 'test -z'.

1620 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1621 Use a single call to AC_DO_TOKENS rather than multiple, for
1623 (_AC_LINK_IFELSE): Test that resulting file is executable.
1624 Problem reported by mwoehlke in
1625 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
1627 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
1628 than creating a file to use with test -x; this is much faster.

1642 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

1644 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):

1646 still doesn't let the program compile.

1650 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
1651 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just

1660 `error.h', and include it, for a `error_at_line' prototype.
1661 Use a nonempty format string in the link test.
1662 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
1663 for a declaration of wait3.

1668 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
1669 can apply to constants too, and that it checks for macro defns.
1670 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

1672 values. Problem reported by Ralf Wildenhues.

1887 broken lex libraries like native ia64-hp-hpux11.22; see
1888 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

2016 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
2017 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
2018 -Wundef -Werror". Problem reported by David Fang in
2019 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
2020 * doc/autoconf.texi (Header Templates, Default Includes):

2039 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
2041 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
2042 problems with arg script text that doesn't end in newline, and
2043 with '-e a...'. Problems reported by Ralf Wildenhues.
2045 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
2047 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
2048 check for libXt by a check for libX11.

2061 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
2063 Fix test suite failures reported by Pierre in
2064 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.

2066 the compiler created a file "b.out" when it didn't create anything
2068 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
2069 Discard stderr too, when invoking the test script.

2079 less skeptical about "volatile", after discussion with
2080 Bruno Haible on bug-gnulib.
2081 (Limitations of Usual Tools): Warn about sed stripping
2082 leading white space from text. From Bruno Haible.
2084 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
2086 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
2087 compiler complains about it, even if things works after the
2088 complaint. Problem reported by Peter O'Gorman.

2091 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
2092 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
2094 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
2096 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
2097 after -R regardless of host. Patrick Welche reports that this

2108 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
2109 under AC_C_VOLATILE.
2110 (Volatile Objects): Be a little less skeptical about what
2111 "volatile" means. Derived from thoughts by Ben Pfaff in
2112 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
2114 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2116 * doc/autoconf.texi: Fix some typos.
2118 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
2120 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2121 more globally, since the 2006-06-30 patch didn't suffice. Problem
2122 reported by Keith Marshall. Also, don't bother with builddir2,
2123 since it shouldn't be needed any more.
2125 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
2127 * doc/autoconf.texi (Generic compiler characteristics):
2128 Document AC_COMPUTE_INT. Fix wrong statements on Default
2129 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
2131 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.

2142 * NEWS: Document previous change.
2144 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
2146 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
2147 Require that long long int be at least 64 bits wide. C99 requires
2148 this and enough programs depend on it so we should check for it.
2149 Bruno Haible reports in
2150 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
2151 that long long int is 32 bits wide with some nonstandard compilers.
2152 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
2154 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
2156 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2157 to a nonexistent file, so that we don't have to worry about
2158 a local site configuration that doesn't use /usr/local.
2159 Problem reported by Keith Marshall in
2160 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
2162 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
2164 * doc/autoconf.texi: Be more consistent about using @acronym with
2165 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
2166 quite right (it talked about "OSF/Tru64", even though the
2167 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
2168 and it even mentioned "OSF 4"!) and at this point there's little
2169 reason to talk about OSF any more, since it died in 1994.
2170 (Specific Compiler Characteristics): Simplify example of
2171 negative-size array.
2172 (File Descriptors): Reorder to make the text flow better.
2173 Remove joke about "appreciate the various levels"; I didn't get it.
2174 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
2175 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
2176 (File Descriptors, Limitations of Usual Tools):
2177 Tone down the advice against renaming or removing open files.
2178 (Limitations of Usual Tools): Add a new section, on 'rm'.
2180 2006-06-26 Stepan Kasal <kasal@ucw.cz>
2182 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
2183 -lXt in LIBS, idea from Karsten Hopp; this was due since
2186 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2187 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2188 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2189 (which belong to Xt, not X itself). See Debian bug 327655.
2191 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2193 * configure.ac (AC_INIT): Bump to 2.60a.
2196 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2200 * configure.ac, NEWS: Update.
2202 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2204 * config/texinfo.tex: Sync from upstream.
2206 * bin/autom4te.in (handle_traces): Transform the `@S|@'
2207 quadrigraph correctly in traces.
2209 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
2212 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
2213 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
2215 * doc/autoconf.texi (Changed Directory Variables): New node,
2216 to document the whole `datarootdir' business a bit better.
2218 * tests/torture.at (datarootdir workaround): Extend test.
2219 Prompted by report by Alexandre Julliard.
2221 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
2223 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
2224 when using default mode of IBM C 6 for AIX. Problem and two-line
2225 fix reported by Larry Jones.
2227 2006-06-22 Alexandre Julliard <julliard@winehq.org>
2229 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
2230 about literal '${datarootdir}' if a definition is found in the
2233 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
2235 * NEWS: Use "M4" rather than "m4" when appropriate.
2236 Problem reported by Eric Blake.
2237 * doc/autoconf.texi: Likewise.
2238 Use @acronym around BSD, GCC, and GNU when appropriate.
2239 (Why GNU M4): Renamed from "Why GNU m4".
2240 (Redefined M4 Macros): Mention that Posix
2241 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
2242 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
2245 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2247 * bin/autom4te.in (handle_output): Do not forbid the empty
2249 * tests/tools.at (autoconf: the empty token): New test.
2251 2006-06-20 Stepan Kasal <kasal@ucw.cz>
2253 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
2254 calls, so that we do not care whether they are LIFO or FIFO;
2255 in the m4_wrap, do not check which diversion is the topmost
2256 one, just check that the stack is balanced at the end.
2257 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
2258 base diversion forever--pop the previous diversion before
2259 opening the new one; consequently, remove the m4_wrap call.
2260 * lib/autotest/general.m4 (AT_INIT): Likewise.
2261 * tests/m4sugar.at: Do not use
2262 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
2264 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
2265 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2267 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
2268 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
2269 Rework example of m4wrap token-pasting trouble so that it doesn't
2270 care whether it's LIFO or FIFO.
2271 Fix some "contrary to"s that are awkward in English.
2273 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2275 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
2276 to `yes' instead of `int$1_t' if the type is found, for more
2277 consistent configure output (where $1 is the number of bits).
2278 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
2279 Suggested by Bruno Haible.
2281 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
2282 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
2283 with system headers. Report by Bruno Haible.
2285 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2287 * config/config.guess, config/config.sub: Sync from upstream.
2289 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
2290 in order to avoid picking up an older installed frozen m4sh.m4f.
2291 Besides an outdated shell startup, this could have been created
2292 by an earlier M4 version with incompatible frozen file format.
2294 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
2296 * README: Recommend m4 1.4.4 instead of 1.4.3..
2297 * doc/autoconf.texi: Likewise.
2298 (Special Chars in Names): Say that $(.FOO) is portable, as
2299 suggested by Stepan Kasal.
2300 (Installation Directory Variables, Build Directories):
2301 (Automatic Remaking, Subdirectories, Fortran Compiler):
2302 (Making testsuite Scripts, Defining Directories):
2303 Quote variable usages better.
2304 (Making testsuite Scripts): Add clean-local rule to makefile
2305 snippet, by Eric Blake.
2306 (Installation Directory Variables): Fix table item font.
2307 Reword slightly to clarify. Generalize advice about
2308 not using special characters to include all file-related
2309 vars, not just VPATH.
2310 (Special Chars in Variables): Warn about special characters in
2312 (Assignments): Clarify default-value example as suggested by
2314 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
2315 (Special Shell Variables): Note leading ./ or ../, as suggested
2317 (Limitations of Builtins): Under cd, warn about CDPATH.
2318 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
2321 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2323 * doc/autoconf.texi (Configuration Actions): Remove duplicate
2324 `@var', for texi2html.
2325 (Systemology): Some more word wrapping, for DVI output.
2326 (autom4te Invocation): The short option for `--melt' is `-M',
2329 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
2331 * doc/autoconf.texi: More formatting and English tweaks,
2332 many suggested by Ralf Wildenhues.
2333 Reword to avoid "@code{...}'s" and the like, since it's ugly
2334 with Emacs info mode. discontents -> woes.
2335 Put a few "will"s back. time stamp -> timestamp.
2336 side-effect -> side effect.
2338 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
2340 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
2341 Warn about $@ not persisting. Problem reported by Julien Danjou in
2342 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
2343 (Special Chars in Names): Renamed from Leading _ in Macro Names.
2344 Mention other special chars, too.
2346 2006-06-14 Eric Blake <ebb9@byu.net>
2348 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
2350 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
2352 * doc/autoconf.texi: Some systematic minor improvements, as
2353 follows. Use "makefile" when talking about makefiles
2354 generally (which might be named "makefile" or "Makefile" or even
2355 "foo.mk"), "Makefile" when talking about a specific makefile
2356 called "Makefile". This unclutters the text from weird quotes
2357 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
2358 values" rather than "@var{foo}s" and similar constructs containing
2359 "}s". Use "Make rules" rather than "Makefile rules". Minor
2360 English-language improvements. Change the prefix "sub-" to "sub"
2362 Put blank lines around examples more consistently.
2363 Avoid "rather" and "very" as intensifiers.
2364 Avoid "will" as an auxiliary.
2365 (Limitations of Make): Split this node into....
2366 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
2367 (Leading _ in Macro Names, Backslash-Newline-Newline):
2368 (Backslash-Newline Comments, Long Lines in Makefiles):
2369 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
2370 (obj/ and Make, make -k Status, VPATH and Make):
2371 (VPATH and Double-colon, $< in Explicit Rules):
2372 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
2373 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
2374 New nodes, resulting from splitup of Limitations of Make.
2375 All cross-references changed. Raise the top node from
2376 a section to a chapter, and all subnodes accordingly.
2377 Redo the introductory wording to match the new organization.
2378 (Installation Directory Variables): Use an example that is
2379 closer to what Autoconf actually does. Mention that VPATH's
2380 value should not contain metacharacters or white space.
2381 (Fortran Compiler): Fix a VPATH bug in an example.
2382 (Leading _ in Macro Names): Mention that this problem is no longer
2383 of practical concern.
2384 (VPATH and Make): Reword the advice to make it clearer
2385 that Autoconf and Automake support VPATH in non-GNU make, but
2386 many packages have bugs in this area.
2387 ($< in Explicit Rules): Refer to Build Directories rather
2388 than using a (non-VPATH-safe) example.
2389 (Automatic Rule Rewriting): Mention the sort of disaster that
2390 can ensue with Solaris-style rule rewriting with VPATH.
2392 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2394 * doc/install.texi (Compilers and Options): Weaken the
2395 suggestion to use GNU make for VPATH builds.
2397 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
2398 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
2400 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
2401 in regular expression.
2403 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2405 * doc/autoconf.texi (Installation Directory Variables):
2406 Drop extra @samp from `@table @samp' item.
2407 (Limitations of Usual Tools): Comment fix.
2408 Do not nest @samp just to point to other table items.
2409 (Writing testsuite.at) <AT_CHECK>: The second argument to
2410 `@dvar' is already @samp'ed.
2411 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
2412 do not use @var in the second argument.

2416 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
2417 $as_shell.exe too. Problem reported by Andreas Buening in
2418 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
2420 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2422 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
2423 `unused variable' compiler warning, for `-Wall -Werror'.
2424 Reported by Jaap Haitsma in
2425 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
2427 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
2429 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
2430 case the compiler dumps core. Problem reported for
2431 OpenServer 5.0.7 by Tim Rice in
2432 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
2433 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2436 2006-06-06 Tim Rice <tim@multitalents.net>.
2438 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
2439 "ERROR" only shows up in "make check" output if there is an

2463 * config/texinfo.tex: Sync from upstream.
2465 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
2466 seen, invoke libtoolize with `--ltdl' argument.
2467 * lib/autom4te.in (Autoreconf-preselections): Adjust.
2469 Suggested by Eric Blake.
2471 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

2481 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2483 * doc/autoconf.texi: Modernize some of the references to Solaris.
2485 2006-06-05 Stepan Kasal <kasal@ucw.cz>
2487 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
2488 message issued by AC_REQUIRE.
2489 * tests/m4sugar.at: Check m4_require's error message.
2490 * tests/base.at: Check AC_REQUIRE's error message.
2491 * tests/local.at (AT_CHECK_M4): New macro, almost identical
2493 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
2495 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
2496 `expout' as the last parameter.
2497 * tests/tools.at: Adapt to the above change.
2499 2006-06-04 Stepan Kasal <kasal@ucw.cz>
2501 * doc/autoconf.texi (Limitations of Usual Tools): Correct
2502 information about race-free implementations of mkdir.

2511 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
2513 * NEWS: GNU make now recommended for VPATH builds.
2514 Mention that some macros are now documented to be obsolescent.
2515 * doc/autoconf.texi:
2516 Prefer "current" to "modern" to describe
2517 currently-used (albeit perhaps old-fashioned) hosts.
2518 Mention which ancient features no longer need to be worried about.
2519 setgid -> set-group-ID
2520 setuid -> set-user-ID (these are the Posix terms)
2521 Fix some misuses of "only".
2522 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
2523 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
2524 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

2531 Mention that these macros are obsolescent.
2532 (Installation Directory Variables): shall -> should
2533 (File Descriptors): Mention that 0, 1, 2 might get reopened.
2534 Mention that it's now safe to use 3 and 4.
2535 (Limitations of Usual Tools): cp -r is now specified by Posix.
2536 Omit longwinded and obsolescent discussion of cp -f.
2537 Modernize discussion of expr, ls.
2538 (Limitations of Make): Modernize discussion of VPATH builds.
2539 Mention $? as a workaround in some cases.
2540 * doc/install.texi (Basic Installation):
2541 Mention "./configure; make; make install" first. Be more
2542 specific about why this file is generic. Remove unnecessary
2543 parens. Remove misleading "only". Remove obsolete advice
2544 about csh. Don't say "configure" takes awhile; say it
2545 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
2546 and CC=c99 rather than CC=c89, as these are blessed by current
2547 Posix. Recommend GNU make if doing a VPATH build.
2549 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
2551 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
2552 examples involving shell prompts.
2554 2006-06-02 Stepan Kasal <kasal@ucw.cz>
2555 and Paul Eggert <eggert@cs.ucla.edu>
2557 * doc/autoconf.texi (Here-Documents): Add details about the
2558 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
2559 use "here-documents" instead of "here documents".
2561 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2563 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

2567 * doc/autoconf.texi (File System Conventions): Warn about ":"
2568 anywhere in directory names.
2570 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
2572 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
2573 about quoting the case statement, just in case.
2574 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
2575 was fixed in ksh93g; reported by Ralf Wildenhues.
2577 2006-05-31 Stepan Kasal <kasal@ucw.cz>
2579 * doc/autoconf.texi (System Services): Do not document

2586 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2588 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
2589 argument with leading hyphen. Problem reported by Paul Eggert.
2591 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2593 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
2594 about quoting ac_try: quote all of it, if any of it seems suspicious.
2595 This means we don't have to worry about ${ or sed any more.
2596 Also, double-quote the case statement, to work around misuses via
2597 underquoting as reported by Ralf Wildenhues in
2598 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
2599 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
2600 undocumented and dangerous macro.

2612 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
2613 since evidently some packages rely on the old, broken behavior.
2614 Problem reported by Ralf Wildenhues in
2615 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
2616 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
2617 pre-2006-05-26 definitions, but leave in the comments that
2618 these macros are dangerous and should not be used.
2619 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
2620 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
2621 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
2622 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
2623 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
2625 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2627 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
2628 the use of 'tr', since this is our only use of 'tr'.
2630 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2631 and Paul Eggert <eggert@cs.ucla.edu>
2633 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2634 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2636 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2638 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2639 the output file in the `${datarootdir}' test.
2641 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2642 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2644 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2645 mention of `datarootdir' in the input file(s), but literal
2646 `${datarootdir}' in the output file, and we haven't warned yet,
2647 then warn as well: the user may have (erroneously) used
2648 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2649 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2650 * tests/torture.at (datarootdir workaround): Extend this test.
2653 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2654 and Paul Eggert <eggert@cs.ucla.edu>
2656 * doc/autoconf.texi (autoheader Invocation): The first argument to
2657 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2658 alternatives and clear up the language a bit.
2660 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2662 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2663 ac_config_guess, ac_config_sub, ac_configure.
2664 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2665 Fix typo that prevented an unnecessary space from being removed.
2666 Problems reported by Ralf Wildenhues in:
2667 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2669 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2671 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2672 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2673 Don't use the term "thread-safe" to talk about mkdir race
2674 conditions, since the problem is more a process than a thread
2675 issue. Problem reported by Stepan Kasal in:
2676 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2677 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2678 the test for 'install' more closely. Look at MKDIR_P first.
2679 Look in the PATH, and at /opt/sfw/bin.
2680 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2681 Don't bother to try mkdir -p, since we already check mkdir --version;
2682 just look at the version number. (There's no easy way to check
2683 for race-free implementations.)
2684 * tests/tools.at (autoconf: subdirectories): Adjust to above
2685 changes, since MKDIR_P now might end in "/mkdir -p".
2687 * doc/autoconf.texi (autoheader Invocation): Mention that the
2688 first arg of AC_DEFINE_UNQUOTED must be a literal.
2689 Problem reported by Ben Pfaff in
2690 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2692 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2693 * doc/autoconf.texi (Special Chars in Variables): New section.
2694 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2695 (Installation Directory Variables): Quote $(datadir) better.
2696 (Limitations of Builtins): Describe some of eval's trickiness.
2698 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2699 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2700 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2701 in front of every arg, not just trailing args. Quote apostrophes.
2702 (_AC_EVAL_ECHO): New macro.
2703 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2704 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2706 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2707 exposed by quoting of eval argument. Put the command on line line
2709 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2710 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2711 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2712 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2713 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2714 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2715 Use eval more safely.
2716 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2717 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2719 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2720 lines, exposed by quoting of eval argument.
2722 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2723 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2725 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2726 initialization of `ac_cv_exeext', do not override it if it was
2727 already set, unless it was set to `no', for compatibility with
2728 Autoconf-2.13, and comment this.
2729 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2730 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2731 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2732 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2733 Document that this test may be overridden by setting
2736 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2738 Revert these two patches:
2740 2006-04-06 Eric Blake <ebb9@byu.net>
2741 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2742 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2745 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2746 Clean up _AC_COMPILER_EXEEXT* macros.
2747 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2748 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2749 ac_file to the name of the default output file and call
2750 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2751 initial `rm' of the candidate files...
2752 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2753 the same list in subsequent `rm' calls, and for the temporary
2754 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2755 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2756 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2757 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2758 no longer needed) by libtool. Make it a cache check.
2759 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2760 copied here by mistake.
2761 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2762 _AC_COMPILER_EXEEXT.
2763 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2764 _AC_COMPILER_OBJEXT directly.
2765 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2767 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2769 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2770 Fix description of how the buggy `sed' works.
2772 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2776 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2777 ENOLCK. Only mention `make -j' when applicable. Only raise
2778 fatal errors when `make -j' is involved. Improve error message.
2780 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2782 * doc/autoconf.texi (Here-Documents): We now know more about
2783 the variable expansion in here documents bug.
2784 Thanks to Tim Rice and Stepan Kasal.
2786 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2787 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2789 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2791 * tests/autotest.at (Multiline command from M4 expansion):
2792 No failure to be expected if the shell quotes newlines in
2793 commands in the `set -x' output. Report by Tim Rice.
2796 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2798 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2799 expansion in the here-documents used by config.status, as that
2800 runs afoul of the Korn shell version M-12/28/93d bug described in
2801 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2802 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2803 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2805 2006-05-23 Jim Meyering <jim@meyering.net>
2807 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2808 Fix typo introduced with 2006-04-02 change. It reversed the sense
2811 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2813 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2814 ac_dB slightly, to save bytes in the script.
2815 Max out at 50 lines, rather than 96; this is more likely
2816 (though not guaranteed) to avoid obscure 'sed' failures.
2818 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2820 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2821 `tr -d -' as bad option argument. Work around this by deleting
2822 an unrelated character.
2823 Report by Tim Rice <tim@multitalents.net>.
2825 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2826 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2827 Stepan Kasal <kasal@ucw.cz>
2829 * doc/autoconf.texi (Particular Programs): Do not promise that
2830 we always prefer the GNU version of the program, and that we
2831 search according to PATH; both rules can have exceptions.
2832 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2833 AC_PROG_SED. Move descriptions of limitations
2834 to the Limitations of Usual Tools section.
2835 (Limitations of Usual Tools) <sed>: Mention script length
2836 limitations with Solaris /usr/ucb/sed.
2837 <grep>: Fix wording for empty alternative. Mention that -c and
2838 -l should not be combined, and that -E and -F should not be
2841 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2842 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2844 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2845 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2847 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2849 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2850 AC_DEFINE is now passed to m4_pattern_allow.
2851 * NEWS: Mention that; likewise for AC_SUBST.
2852 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2853 the parameter to m4_pattern_allow.
2854 * tests/tools.at: Add a check for that.
2856 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2858 * lib/autoconf/status.m4: Fix typos.
2860 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2862 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2863 only the files that this macro generates.
2865 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2867 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2868 the HP-UX sed limitation of 99 commands, labels do not count.
2869 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2871 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2873 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2875 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2876 Import the following fix from coreutils:
2878 2006-01-13 Jim Meyering <jim@meyering.net>
2880 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2881 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2882 not double-quote uses of that variable, to accommodate the rare
2883 case in which getmntent is available in none of the libraries
2884 checked. This happens at least on FreeBSD 5.0.
2886 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2888 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2889 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2890 some other programs unwisely rely on these undocumented vars.
2891 But put in warning comments about them.
2892 Problem reported by Ralf Wildenhues in
2893 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2894 * NEWS: Document that these variables are intended to go away.
2896 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2898 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2899 and set the language to C++ (analogous to the equivalent Fortran
2902 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2903 * doc/autoconf.texi (C++ Compiler): Document it.
2904 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2907 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2909 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2910 that caused config.status to generate 100-command sed scripts; the
2911 portable limit is 99.
2913 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2915 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2916 variable `ac_d' instead of `d' to avoid infringing namespace.
2917 Report by Ralf Menzel.
2919 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2921 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2922 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2923 * tests/tools.at (autoconf: subdirectories): New test, taken from
2924 the corresponding problem report by Ralf Wildenhues in:
2925 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2927 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2928 Quote some uses of shell variables if they might suffer unexpected
2929 globbing. This doesn't fix all instances of quoting problems that
2930 I found, just the easy ones that look safe.
2931 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2932 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2933 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2934 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2935 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.

2942 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2944 * bin/autoreconf.in ($help): Reword according to the manual.
2945 Suggested by Olly Betts.
2947 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2948 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2950 * bin/autoreconf.in: Pass the directory argument to
2951 `require_configure_ac'. Fix comment.
2952 * tests/torture.at (Configuring subdirectories): Expose this.
2953 Reported by Olly Betts.
2955 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2957 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2958 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2959 Automake as follows:
2961 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2962 `$configure_in' instead of `configure.in', to preserve
2963 directory component.
2965 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2967 * config/config.guess, config/config.sub, config/texinfo.tex,
2968 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2970 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2972 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2973 test for C99 conformance; (bool) 0.5 is an integer constant
2974 expression, but (bool) -0.5 is not. Problem reported by Fedor
2975 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2977 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2979 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2980 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2981 Warn about obsolete install-sh files. Remove stray sentence
2982 fragment and fix cross reference.
2983 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2984 install -d; this undoes the 2006-05-10 change.
2985 (MKDIR_P): Mark with AN_MAKEVAR.
2986 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2987 that we don't require $INSTALL to be thread-safe. Move comments
2988 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2989 of AC_PROG_INSTALL. Output a message saying that we're checking
2990 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2991 MKDIR_P instead of AC_SUBST.
2992 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2993 Special magic for MKDIR_P, too.
2994 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2996 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2998 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
3000 Sync from Automake, as follows:
3002 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3003 * config/install-sh: Initialize IFS, so field splitting isn't
3005 * config/mkinstalldirs: Likewise.
3006 * config/missing: Remove superfluous quotes. Replace all uses of
3007 `[' by `test', for consistency, and for..
3008 * config/missing (sed_minuso, sed_output): New variables.
3009 (autom4te, help2man, makeinfo): Use them. Unifies detection of
3010 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
3011 Fixes `missing' to detect `--output' for help2man. Fixes
3012 PR automake/483. Report by Dennis J. Linse.
3013 (autom4te): Document in `missing --help'.
3015 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3017 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
3018 * config/install-sh: Don't use 'path' to talk about file names,
3019 as per GNU coding standards. Close a race condition reported by Ralf
3020 Wildenhues and Stepan Kasal. There is still a race condition
3021 on hosts that predate Posix 1003.1-1992, but we can't help this.
3022 Don't mishandle weird characters like space on pre-Posix hosts.
3023 Invoke mkdir at most once per dir arg on pre-Posix hosts.
3024 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
3025 AC_PROG_MKDIR_P from AS_MKDIR_P.
3026 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
3027 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
3028 earlier editions are not (including Automake 1.8.3).
3029 Do not suggest mkinstalldirs for thread-safety.
3030 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
3031 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
3032 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
3033 presence of special characters and race conditions.
3034 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
3035 in Autoconf's name space.
3037 2006-05-10 Bruno Haible <bruno@clisp.org>
3038 and Paul Eggert <eggert@cs.ucla.edu>
3040 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
3041 from Automake with minor changes.
3042 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
3044 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3046 * config/install-sh: Update to Automake CVS version, as follows:
3047 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3048 * lib/install-sh: Simplify the expr implementation of dirname.
3049 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
3050 * lib/install-sh: Handle --, and diagnose unknown options.
3052 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3054 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
3055 `./autom4te' to create `./testsuite', since the `all' target
3056 will ensure its presence, but `installcheck' should not create
3057 the uninstalled wrappers.
3059 * tests/torture.at (Unusual Automake input files): Skip if we
3060 detect automake < 1.8.
3062 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3064 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
3065 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
3066 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
3069 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3071 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
3072 munge (multiple) white space and other oddities.
3073 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
3074 single quotes in variable assignment.
3075 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
3076 and similar failures by adding multiple spaces, tabs, and other
3078 Report and different test suggested by Francesco Romani
3079 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
3081 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
3082 single quotes, we only need to search for single quotes; this
3083 both simplifies the search pattern, and makes us less
3084 susceptible to `echo' variations for arguments not containing
3086 (_AC_ARG_VAR_VALIDATE): Likewise.
3088 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3090 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
3091 `$*' and IFS concatenation issue with traditional shells and
3092 bash-2.04. Report by Seanster@Seanster.com.
3094 2006-05-03 Bruno Haible <bruno@clisp.org>
3096 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
3097 precisely which Mac OS X versions have the od problem.
3099 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3101 * doc/autoconf.texi: Use @option systematically.

3104 and Bruno Haible <bruno@clisp.org>
3106 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
3108 (Integer Overflow): Mention the special case of integer division
3111 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3113 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
3114 traditional shells like the Solaris one that do not use the
3115 first IFS character for assembling `$*'.
3116 Prompted by a related report from autoconf_bug@nro.ca.
3118 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
3119 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3121 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
3122 Mention more problems with the -e option.

3127 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
3129 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
3130 in URLs to improve DVI formatted output (requires texinfo 4.6).
3131 (System Services, Systemology, Shellology): Likewise.
3132 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
3135 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
3137 (Runtime): Fix macro argument names to match description:
3138 `action-if-found' -> `action-if-true' and similarly.
3139 (Obsolete Macros): Likewise.
3140 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
3141 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
3142 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
3144 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3146 * doc/autoconf.texi (Limitations of Make): Clean up markup.
3149 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

3176 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
3177 since as_me isn't set yet.
3179 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3181 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
3182 a few minor bugs in this area.
3184 * doc/autoconf.texi (Programming in M4sh): Comment out the
3185 documentation of AS_BASENAME, for now.
3186 (Shell Substitutions): Do not use AS_DIRNAME in an example.
3187 (Limitations of Builtins) <basename>: Do not refer to
3189 * bin/autoconf.as (me): Don't use AS_BASENAME.
3190 (dir): Remove the unused variable.
3191 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
3192 AS_DETECT_REQUIRED. All uses changed.

3215 with more accuracy and detail.
3217 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3219 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
3220 Archive is not officially `GNU' any more. Update URL.
3221 (Defining Directories): Likewise
3222 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
3224 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3226 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
3227 newline from the `trap' code to finish `config.log'; the NetBSD
3228 /bin/sh resets the exit status after an empty command, as
3229 documented in doc/autoconf.texi.
3230 Reported by Dalibor Topic <robilad@kaffe.org>.
3232 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
3234 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
3235 Suggested by Bruno Haible.
3237 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
3239 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
3240 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
3241 Instead, just list the shells that we know work.
3242 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
3243 changed. Be more cautious about the _cv_ variable.
3244 * tests/tools.at (Syntax of the shell scripts): Check the
3245 _cv_ variable once, at first, to avoid an internal autoconf error
3246 when sh -n does not work.
3248 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3250 * lib/Autom4te/FileUtils.pm: Sync from Automake.
3252 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
3254 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
3255 use ">&-" since we're only 99.999% sure that this is portable,
3256 and since the MinGW bug is fixed in a different way.
3257 * lib/autotest/general.m4 (AT_INIT): Likewise.
3259 2006-04-16 Stepan Kasal <kasal@ucw.cz>
3261 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
3262 before opening config.log, to avoid hitting a bug on MinGW.
3264 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
3266 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
3267 AS_MESSAGE_LOG_FD before reopening it onto the log file.
3268 This works around a MinGW bug reported by Eric Paire.
3269 Make sure that all writes to the log file append to it,
3270 rather than possibly losing data.
3271 * lib/autotest/general.m4 (AT_INIT): Likewise.
3273 2006-04-14 Stepan Kasal <kasal@ucw.cz>
3275 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the

3284 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3288 * Makefile.maint (news-date-check): Do not require a leading `*'
3289 before the release date in NEWS.
3291 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3292 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3294 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
3295 the instantiated file do not contain the string 'datarootdir'
3296 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
3297 @mandir@, replace the reference '${datarootdir}' by the value.
3298 * tests/torture.at (datarootdir workaround): New test.
3299 * NEWS: Advertise this temporary fixup.
3300 Based on a patch by Bruno Haible, reported and analyzed by
3301 Paul Eggert and Noah Misch.
3303 2006-04-12 Eric Blake <ebb9@byu.net>
3305 * tests/autotest.at (Debugging a failed test): Fix comment.
3307 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3309 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
3310 all the changes since 2006-04-07.
3312 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3314 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
3315 succeeded, but `ln -s file dir' failed, take care to remove the
3316 leftover target before the next test, to prevent its spurious
3317 failure; also make sure `ln file dir' works before selecting it.
3318 Thanks to Keith Marshall for pointing this out.
3321 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
3322 assignments in `at_debug_args', so that we put them correctly
3323 in the `run' script.
3324 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
3325 Reported by Eric Blake.
3327 2006-04-11 Eric Blake <ebb9@byu.net>
3329 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
3330 top-level tests after micro-suite has been run. Used in...
3331 (Debugging a successful test, Debugging script and environment),
3332 (Debugging a failed test): ...these new tests. The first of these
3334 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
3335 macro, split out from...
3336 (AT_INIT): ...here, so that using -d also generates a run script.
3337 Document that -d inhibits top-level logging.
3338 * doc/autoconf.texi (testsuite Invocation): Document that -d only
3339 inhibits top-level logging; debug scripts are created.
3341 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
3343 * tests/autotest.at (Empty test, Empty check): New test to check it.
3345 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
3348 2006-04-10 Stepan Kasal <kasal@ucw.cz>
3350 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
3351 the files if a problem appears. Make the empty *.at files
3352 read-only, too. Proposed by Ralf Wildenhues.
3354 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3356 * config/Makefile.am: Add comment to force updated Makefile.in.
3358 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
3359 space only patch to this file, this patch causes the Makefile.in
3360 files that include freeze.mk to be updated, and thus have a
3361 newer time stamp again, which in turn makes a pristine CVS
3362 checkout have correct time stamps.
3364 * Makefile.maint (cvs-sv): New macro, to be used..
3365 (config.guess-url_prefix, config.sub-url_prefix)
3366 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
3367 point to CVS text checkout of Gnulib files.
3368 (copyright-check): Bump current year.
3369 (announcement): Do not hard-wire `./announce-gen'.
3370 (cvs-update): Propagate failures of `cvs' and `move-if-change'
3372 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
3374 (wget_files): Update config.guess, config.sub, texinfo.tex by
3375 `wget-update', now that their URLs work again.
3377 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3379 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
3380 Problem noted by Paul D. Smith.
3382 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3384 * doc/autoconf.texi: Remove unused words from word list.
3385 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
3386 .x-sc_trailing_space: New files.
3388 * doc/standards.texi: Sync from gnulib.
3390 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
3391 `LIBOBJDIR' as experimental.
3393 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
3394 with a target directory; it's internally implemented as `cp'
3395 anyway, but since Autoconf advertises the possibility to use
3396 a target directory when LN_S is `ln -s', we need to find out.
3397 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
3398 analyzed by Keith Marshall <keith.marshall@total.com>.
3402 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3404 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
3405 confdefs.h as-is. In general, if it has backslash-newline or the
3406 like, then it doesn't work either to sort or to remove empty
3409 2006-04-09 Stepan Kasal <kasal@ucw.cz>
3411 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
3413 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
3415 * lib/autom4te.in (Automake-preselections): Preselect
3418 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3420 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
3421 apostrophe within a single-quoted string, as this is the usual
3422 tradition and is easier to read than '"'"'. Don't rely on the
3423 shell treating "$/" like '$/'. Use a more-consistent indenting
3426 2006-04-09 Eric Blake <ebb9@byu.net>
3428 * tests/autotest.at (Backquote command substitution),
3429 (Multiline backquote command substitution): Remove mistaken
3430 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
3432 (Parenthetical command substitution, Multiline parenthetical
3433 command substitution): here.
3435 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

3468 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
3469 (C Compiler): Move AC_C_LONG_DOUBLE to ...
3470 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
3471 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
3472 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
3473 (Coding Style). Don't mention m4_expand_once.

3495 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
3497 2006-04-08 Stepan Kasal <kasal@ucw.cz>
3499 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
3500 of the warning introduced by the 2001-08-28 change.

3510 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3512 Revert the patch from 2006-04-01 and only improve
3513 _AS_DETECT_BETTER_SHELL:
3515 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
3516 skip nonexistent directories.
3517 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
3518 only shell candidates which exist.
3519 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
3520 * lib/autotest/general.m4 (AT_INIT): No need to give three
3521 parameters to _AS_PATH_WALK.
3523 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
3524 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3526 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
3527 distinguish m4sugar macros.
3528 * tests/tools.at (autoupdating with aclocal and m4_include):
3529 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
3530 test case by Noah Misch <noah@cs.caltech.edu>.
3532 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3534 Revert my change from 2006-03-17, in other words:
3535 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
3537 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
3538 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
3541 2006-04-07 Eric Blake <ebb9@byu.net>
3543 * doc/autoconf.texi (Programming in M4sh): Document that
3544 AS_MKDIR_P exits the script on failure.
3545 * lib/autotest/general.m4: Remove redundant AS_ERROR.
3547 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3549 * config/elisp-comp, config/install-sh, config/mdate-sh,
3550 config/missing, config/mkinstalldirs: Sync from Automake.

3565 Paul Eggert <eggert@cs.ucla.edu>,
3566 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3568 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
3569 whether `set' quotes correctly: redirect stderr of the tested
3570 `set', and use a subshell, for Ultrix; use `sed' instead of
3571 `grep' for zsh `set' which may write binary output; match only
3572 at the beginning of a line, to avoid false positives.
3573 In order to avoid false positives by unrelated variables with
3574 multiline content, put the dump algorithm in a subshell and
3575 unset all variables containing newlines (except some which are
3576 special to the shell). Warn about cache variables that are
3579 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3622 ac_config_<foo>s again, sometimes normalized, sometimes not.
3623 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
3624 (AC_CONFIG_COMMANDS): Do not do so here.
3625 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
3626 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
3627 2005-07-25 rewrite. Noticed by Noah Misch.
3629 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
3630 _AC_PRESERVE_HELP_ORDER, ...
3631 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
3633 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
3634 inside m4_expand_once; it is redundant.
3636 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
3637 for --help from Cygnus `configure.'
3639 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

3652 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
3653 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
3654 * doc/autoconf.texi (Help Formatting): New node.
3655 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
3657 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3659 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
3660 lib/autoconf/specific.m4, lib/autoconf/status.m4,
3661 lib/autoconf/types.m4, lib/autotest/general.m4,
3662 tests/mktests.sh, tests/torture.at: White space cleanup:
3663 remove some SPACE before TAB, or add quoting ('' or @&t@).
3665 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
3667 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
3669 2006-04-05 Eric Blake <ebb9@byu.net>
3671 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
3672 empty test suite works.

3681 normalizing it, consistent it with previous releases.
3682 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
3684 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3686 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
3687 Use simplified args that Eric Blake originally suggested.
3689 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
3691 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
3692 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
3693 Use 'comm' rather than N instances of grep; this also fixes a bug
3694 whereby substrings were incorrectly matched, causing us to not
3695 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
3696 (exclude_list): Exclude empty macros.
3697 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

3710 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
3712 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
3713 report request when we have no AC_PACKAGE_BUGREPORT.
3715 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3719 * tests/mktests.sh: Update copyright year in the header of the
3722 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
3723 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
3724 typedef'ed restricted pointer, to catch a compiler bug on
3725 HP-UX 11.x, and fix warnings so it passes with -Werror.

3747 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
3748 to log, point to testsuite output tree.
3750 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
3752 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.

4570 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
4571 by the function rather than ignoring it.
4572 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
4573 comparing its address. Intel's interprocedural optimization was

4625 2005-09-06 Stepan Kasal <kasal@ucw.cz>
4627 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
4628 calls, so that the final expansion of this macro is shorter.
4629 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
4630 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
4631 the cleanup there. Use AS_VAR_* macros, to be more general.
4632 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.

4661 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
4662 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

4683 Update limitations about when to call AC_CONFIG_HEADERS.
4684 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4685 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4686 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4687 ``Configuration Actions''; fix their index entries.
4689 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4690 options correctly. Process N-M as M-N if M is smaller than N.
4691 Process ranges correctly so that N-N will run only N.
4692 Sort and uniquify the tests that will be run. If there is more
4693 than one test, reinsert the banners for the tests.

4699 before passing the macro name to AH_TEMPLATE.

4720 Prepend to LIBS, not append, in examples.
4722 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4724 When building in place, set srcdir="."; suggested by Tim Van Holder.
4726 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4727 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4728 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4729 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
4730 does not mean "no --srcdir option".
4732 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4734 * tests/autoscan.at (autoscan): New file.
4735 * tests/suite.at: Use it.
4736 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
4737 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
4739 * tests/autotest.at (Keywords): Test keywords combinations.
4741 2005-08-12 Stepan Kasal <kasal@ucw.cz>
4743 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
4744 add "2>&1"; gzip 1.2.4 prints help on stderr.
4746 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4748 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
4749 was pushdef'ed twice while popped only once. Push it only once.
4750 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
4752 2005-07-26 Stepan Kasal <kasal@ucw.cz>
4754 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
4755 prefixed by mere "===", not "configure: === ".
4757 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
4759 * Makefile.maint: Update from Bison.
4761 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
4762 "<tab>" in comment, so that the point is understandable.
4764 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4766 Rewrite substantial part of lib/autoconf/status.m4.
4767 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4768 and CONFIG_COMMANDS are not processed in four separate loops.
4769 Instead, there is one main loop. This alows that the common code
4770 is expanded only once, thus config.status (and configure) is smaller.
4772 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4773 the AC_LIST_FILES and cousins macros are no longer used.
4775 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4776 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4777 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4778 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4779 contain the initialization, nor the for loop, nor the associated
4780 commands; all these go to ...
4781 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4782 _AC_OUTPUT_CONFIG_STATUS.
4783 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4784 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4785 (_AC_OUTPUT_FILE): The creation of the sed script ...
4786 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4787 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4788 _AC_OUTPUT_MAIN_LOOP.
4789 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4790 _AC_CONFIG_COMMANDS): Use ...
4791 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4792 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4793 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4794 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4795 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4796 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4798 (_AC_CONFIG_UNIQUE): Update.
4799 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4800 Replaced by this ...
4801 (_AC_LIST_TAGS): ... new common macro.
4802 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4803 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4804 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4805 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4806 this didn't belong to the `config commands' section.
4807 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4808 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4809 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4810 to the `config commands' section either.
4811 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4812 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4814 ... and many changes to the comments nearby.
4816 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4817 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4818 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4819 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4820 (#define header templates): The comment at the top of the generated
4821 header now includes the name(s) of the source file(s).
4823 Several unrelated small changes:
4825 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4826 parameter to AC_DIAGNOSE.
4827 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4828 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4829 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4830 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4832 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
4833 in AC_OUTPUT doesn't double-quote it either.
4834 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
4837 2005-07-10 Stepan Kasal <kasal@ucw.cz>
4839 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
4840 versions of Portland Group compiler produce single- and double-quoted
4841 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
4842 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
4844 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
4846 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4847 This is a corrected version of yesterday's patch.
4849 2005-07-07 Stepan Kasal <kasal@ucw.cz>
4851 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full

4854 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
4855 ac_cv_build_alias to ac_build_alias.
4856 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
4858 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
4859 change eliminates it. Problem reported by Alexandre Duret-Lutz.
4860 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
4861 (AC_ARG_VAR): ... here.
4862 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
4865 Keep a list of all precious variables and process them with one simple
4866 for loop, instead of expanding all commands, or, OTOH, complicated
4867 processing of output of "set".
4868 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
4869 variable names in new macro...
4870 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
4871 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
4872 a loop to assign all ac_env_* and ac_cv_env_* variables.
4873 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
4875 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4876 its value to shell variable ac_precious_vars and call
4877 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
4878 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
4879 _AC_ARG_VAR_VALIDATE.
4881 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

4899 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4900 They are generated by the Tru64 v5.1B shell.
4902 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4904 Fix my changes from 2005-07-01; reported by Noah Misch.
4905 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
4906 description, the macro now accepts only a single tag.

4909 Fix cases when the varsions of Autoconf and Autotest don't match.
4910 Reported by Noah Misch.
4911 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
4912 at_top_builddir, for compatibility with older autotest.
4913 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
4914 is not set, use at_top_builddir, for compatibility with older
4915 versions of autoconf.
4917 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4919 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
4920 Problem reported by Patrick Welche.
4922 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4924 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4925 sed substitution command, so that we allow | in program prefixes
4926 and program suffixes. (& is a problem anyway; we're not fixing
4928 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4929 configure_input, top_builddir, srcdir, etc.
4930 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4931 PATH_SEPARATOR in AUTOTEST_PATH.
4933 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
4935 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
4936 for loop over config.site files using `set', to allow

4939 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
4941 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
4942 directories with weird names. Apparently some people like living
4943 on the edge. However, improve the test that "pwd" actually does
4944 report a name for the working directory.
4945 * NEWS: Remove the claim that we test for funny chars in dir names.
4947 2005-07-01 Stepan Kasal <kasal@ucw.cz>

4964 document to output the default config_* lists to config.status.
4965 Don't recognize option --file, if the functionality is not there.
4966 Likewise for --header; moreover, recognize --he and --h as shortcuts
4967 for --help in that case.
4969 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4970 matches the order of execution. No code changed.

4992 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4993 (AC_SUBST): Call it.
4994 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4995 the directory specific variables; but don't call it for configure_input.
4997 2005-06-28 Derek Price <derek@ximbiot.com>
4999 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
5002 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
5004 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
5005 directory have inherent problems with special characters like spaces,
5006 due to limitations in Make syntax. Problem reported by Alexandre
5008 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
5009 Also, fix Tru64 porting problem with shell patterns,

5021 from Justace Clutter.
5022 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
5023 variable into diagnostic. Make the diagnostic an error, not a warning,
5024 because we really don't support spaces and suchlike in dir names.
5025 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
5026 Don't worry about backslashes in srcdir; it can't happen now.
5027 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
5028 Simplify ac_optarg handling.
5029 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

5043 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
5045 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

5051 2005-06-21 Stepan Kasal <kasal@ucw.cz>
5053 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
5054 b, t, r, w commands require single space, while : cannot have any.
5055 (Special Shell Variables): Fix sed code this in the example.
5056 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
5057 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
5059 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

5069 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
5070 * doc/autoconf.texi:
5071 Don't mention Solaris versions so much, if a
5072 problem is common to all extant versions of Solaris. Say "SunOS
5073 4" instead of "SunOS" for SunOS 4.
5074 (awk): Mention more of the limitations of traditional Awk.
5075 (cat): Don't talk about cat -v.
5077 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
5079 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
5080 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

5085 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
5086 on Mac OS X 10.4 reported by Peter O'Gorman in:

5088 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
5089 Use shell builtins rather than 'expr', to work around expr bug.
5091 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
5093 * doc/autoconf.texi: "filesystem" -> "file system".
5094 "behaviour" -> "behavior".
5095 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
5096 * lib/autoconf/general.m4: Omit blank after ":" sed command,
5098 * lib/m4sugar/m4sh.m4: Likewise.
5099 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
5100 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
5102 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
5103 (.x.1): Ignore the time stamp in the .TH line when deciding whether
5104 to update the man page. That way, we don't have to check in new
5105 man pages every month.
5107 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
5108 quotes and backslashes. Patch from Derek Price.

5115 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
5117 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
5118 -u, since it outputs chatter if the input files are the same.
5119 Problem reported by Ralf Menzel.
5121 2005-06-08 Derek Price <derek@ximbiot.com>
5123 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
5124 renaming them since they are about to be redefined anyhow.
5126 2005-06-08 Derek Price <derek@ximbiot.com>
5128 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
5129 redefined M4 macros to this node. Document m4_include & m4_sinclude.
5130 Move m4_undefine to alphabetical order.
5132 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
5134 * README: Recommend GNU M4 1.4.3 or later.
5135 * doc/autoconf.texi (Introduction): Likewise.
5136 Reword to avoid some formatting glitches.
5137 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
5138 Clarify explanation of HP compiler bug.
5139 Redo example output tp match current CVS snapshot.
5140 Use @example.org in email addresses when the examples
5141 might get inadvertently cut-and-pasted into user code.
5142 Remove example of autom4te usage that doesn't seem to work now.
5143 Use modern AC_INIT (except when the example is meant to be
5144 shown with Autoconf 2.13).
5145 Update ksh info for Solaris 9 and later.
5147 Modernize description of Automake versions a bit.
5148 Don't claim a future version of Autoconf is near.
5149 * doc/install.texi: Reword to avoid some formatting glitches.
5151 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5154 follows its own advice about quoting better.
5155 Reword to avoid some formatting glitches.
5156 * doc/installt.exi: Reword to avoid some formatting glitches.
5158 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
5159 Tru64 ksh pattern matching bug. Reported against Libtool by
5160 Albert Chin <libtool@mlists.thewrittenword.com> and
5161 Nicolas Joly <njoly@pasteur.fr>.
5163 2005-06-06 Stepan Kasal <kasal@ucw.cz>
5165 m4_cdr of one-member list was [[]] (one-member list containing an
5166 empty string) instead of [] (an empty list. Callers were skewed to
5167 match this misbehaviour. As a consequence of this:
5168 - m4_foreach([x], [], [foo]) expanded to `foo', while
5169 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
5170 This bug has been fixed:
5172 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
5173 expand to an empty string; print error msg if called without
5175 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
5176 misbehaviour; handle [] and [[]] correctly.
5178 2005-06-06 Stepan Kasal <kasal@ucw.cz>
5180 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
5181 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
5182 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
5184 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
5186 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
5187 swallow records with more than 99 fields.
5188 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
5189 parse the long line.
5191 2005-06-04 Stepan Kasal <kasal@ucw.cz>
5193 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
5194 swallow literals longer than 399. Reported by Ralf Wildenhues.
5195 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
5196 to workaround this limitation.
5198 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
5200 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
5201 to gfortran, and make these the first two compiler names
5202 checked (following the general autoconf preference for gcc).
5204 2005-06-03 Stepan Kasal <kasal@ucw.cz>
5206 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
5207 (DISTCLEANFILES): Remove $(check_SCRIPTS).
5208 (testsuite): Make sure autotest.m4f is up-to-date before using it.
5210 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
5212 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
5213 expression of unbounded size when processing the --list
5214 option. This runs afoul of a limit of 399 bytes per regular
5215 expression on AIX. Problem reported by Ralf Wildenhues.
5217 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
5219 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
5220 * doc/autoconf.texi (Particular Headers): Reword example
5221 for multiline stdbool replacement.
5222 (Setting Output Variables): Reword text a bit. Don't
5223 give all the details about |#_!!_#|.
5224 Reword description of line replacement.
5226 2005-05-31 Dan Manthey <dan_manthey@partech.com>
5228 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
5229 now contain newlines, and substituted files must be referenced on
5230 a line alone; the sed scripts to substitute them are now very
5232 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
5233 commands can be put in a sed script portably.
5234 * doc/autoconf.texi (Setting Output Variables): Document above
5235 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
5236 use of multiline substitution.
5237 * tests/torture.at: No longer expect substitution of newline to fail.
5239 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
5241 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
5242 From Ralf Menzel (trivial change).
5244 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
5246 * tests/local.at: Don't attempt to check for negated character
5247 classes in shell scripts. The test was too brittle.
5249 2005-05-25 Stepan Kasal <kasal@ucw.cz>
5251 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
5252 * doc/autoconf.texi (Limitations of Builtins): Document this
5255 2005-05-24 Stepan Kasal <kasal@ucw.cz>
5257 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
5258 common code; used in many places in the tree.
5259 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
5260 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
5262 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
5264 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
5265 messages when ac_unique_file is not found.
5266 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
5267 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
5268 commands, for consistency with AC_MSG_ERROR and such.
5270 * bin/autoconf.as: Make more use of "shift 2" in option processing.
5272 * bin/Makefile.am: Merge the two rules for creating scripts.
5274 2005-05-23 Stepan Kasal <kasal@ucw.cz>
5276 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
5277 obsolete; it was never documented.
5278 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
5280 2005-05-20 Stepan Kasal <kasal@ucw.cz>
5282 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
5283 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
5284 (ac_top_builddir): ... this ...
5285 (ac_top_build_prefix): ... to this; the old name is also kept, for
5286 backward compatibility.
5287 (ac_top_builddir_sub): New variable, without the trailing slash,
5289 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
5290 * doc/autoconf.texi (Configuration Actions): Rename
5291 ac_top_builddir to ac_top_build_prefix.
5292 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
5293 at_top_builddir to at_top_build_prefix.
5294 * lib/autotest/general.m4 (AT_INIT): Likewise.
5296 2005-05-20 Stepan Kasal <kasal@ucw.cz>
5298 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
5301 2005-05-17 Stepan Kasal <kasal@ucw.cz>
5303 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
5304 argument to m4_foreach. I guess it was necessary in the past,
5305 but I think it's a no-op now.
5307 2005-05-17 Stepan Kasal <kasal@ucw.cz>
5309 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
5310 ``cat <<_ACEOF'' commands to one.
5311 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
5312 * lib/autoconf/status.m4: On various places, use expr instead of
5314 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
5315 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
5316 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
5318 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
5319 the wrong patterns between ``case'' and ``esac.'' The previous
5320 code had false positives.
5322 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
5324 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

5367 2005-05-13 Stepan Kasal <kasal@ucw.cz>
5369 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
5371 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
5372 enough arguments, similarly as in m4_bpatsubsts.
5374 2005-05-12 Stepan Kasal <kasal@ucw.cz>
5376 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
5379 2005-05-11 Stepan Kasal <kasal@ucw.cz>
5381 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
5382 for absolute directory names in one loop.
5383 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
5384 abbreviations of --version and --debug.
5386 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
5388 * doc/autoconf.texi (Autoconf Language): Be more precise about
5389 quoting rules. Problems noted by Stepan Kasal.
5390 Also, throughout this document, be more careful about white space.
5391 "blank", "white space", and "space" all have different meanings
5392 and we should be careful to say what we mean.
5394 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
5396 Fix C++ related problems reported by Werner Lemberg.
5397 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
5398 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
5399 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
5400 avoid problems with C++ and throw.
5401 * tests/compile.at: .cpp, not .cc.
5403 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
5405 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5407 * doc/autoconf.texi (Generic Functions): Typos.
5409 2005-05-02 Gary V. Vaughan <gary@gnu.org>
5411 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
5412 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
5413 set by latest automake.
5415 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
5417 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
5418 outputs 0 on GNU/Linux these days.
5420 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
5422 * doc/autoconf.texi (Autoconf Language): Add more description
5423 about quoting heuristics.
5424 (Limitations of Builtins): Describe "set -" problems.
5426 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5428 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
5431 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
5432 by AC_DEFINE; it was a mistake.
5433 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
5435 2005-04-25 Stepan Kasal <kasal@ucw.cz>
5437 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
5439 2005-04-22 Stepan Kasal <kasal@ucw.cz>
5441 * doc/autoconf.texi (External Software): Quadrigraphs are not
5442 processed correctly in AS_HELP_STRING; avoid this in the examples.
5443 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
5444 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
5445 comment and reduce m4_default([foo], []) to [foo].
5446 (m4_strip): Update the explanation.
5448 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
5450 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
5451 Remove core.conftest.* too; it's generated by Tru64 5.1.
5452 Problem reported by Jennis Pruett.
5453 * lib/autoconf/functions.m4
5454 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
5455 Don't bother to remove core files; AC_RUN_IFELSE should do that
5458 2005-04-19 Stepan Kasal <kasal@ucw.cz>
5460 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
5462 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
5464 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
5465 Report from Horst Wente.
5467 2005-04-15 Stepan Kasal <kasal@ucw.cz>
5469 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
5472 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
5474 * doc/autoconf.texi (External Software, Package Options): Add
5475 examples showing how to implement --with-* and --enable-* options.
5477 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
5479 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
5480 as well as configure.in. Problem reported by Gregorio Guidi.
5482 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
5484 * doc/autoconf.texi (Particular Functions): Use gnulib's current
5485 pattern for alloca snippet.
5487 2005-04-04 Stepan Kasal <kasal@ucw.cz>
5489 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

5497 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
5498 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
5500 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5502 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
5503 Merge `-z option' as well for the benefit of Solaris link flags. Pass
5504 whole-archive (-zallextract, -zdefaultextract) options in the hope of
5505 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
5506 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
5508 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
5510 * NEWS: The configure command now warns you if you attempt to use
5511 a directory whose name contains a special character like space,
5513 * doc/autoconf.texi (Installation Directory Variables): Allow
5514 "," in file names. Do not use \@; it's not a portable regexp.
5515 * bin/Makefile.am (edit): Likewise.
5516 * lib/Makefile.am (edit): Likewise.
5517 * tests/Makefile.am (edit): Likewise.
5518 * tests/semantics.at: Likewise.
5519 * tests/torture.at: Likewise.
5520 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
5521 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
5522 * doc/autoconf.texi (File System Conventions): Warn about
5523 unportable file names.
5524 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
5526 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
5527 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
5528 ac_pwd, and quote srcdir.
5529 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
5531 * doc/autoconf.texi: Fix some systematic formatting problems.
5532 ".)" needs a following @: if not at the end of a sentence, and
5533 similarly for "!)". "etc." should be preceded by a comma.
5534 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
5536 2005-03-22 Bruno Haible <bruno@clisp.org>
5538 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
5539 argument is often called 'build-aux'.
5541 2005-03-07 Stepan Kasal <kasal@ucw.cz>
5543 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
5544 macro AC_TRY_LINK is obsolete.
5545 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
5548 2005-02-24 Stepan Kasal <kasal@ucw.cz>
5550 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
5551 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
5552 from a Common Lisp's `cl'.
5553 (AC_PROG_CXX): Behave according to the documentation: don't
5554 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
5555 make the variable CCC precious; use `cl.exe', not `cl'.
5557 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5558 Alexandre Duret-Lutz <adl@gnu.org>
5560 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
5561 /dev/null, as "configure" shouldn't read stdin, and this insulates
5562 us from problems (e.g., when testing for "cl"). Also, do this
5563 redirection before invoking "hostname" or "uname", and keep the
5564 original input stream available via...
5565 (AS_ORIGINAL_STDIN_FD): ... this new macro.
5566 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
5567 bother with "</dev/null" since it's now done at the top of
5569 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
5570 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5571 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5572 * doc/autoconf.texi (File Descriptor Macros): New section.
5573 (Printing Messages): Mention it.
5574 * tests/base.at (Input/Output): New test.
5576 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5578 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
5579 newline if neither \c nor -n work, as that would output two
5580 newlines. Prefer -n to \c. Reported by Stepan Kasal.
5582 2005-02-12 Stepan Kasal <kasal@ucw.cz>
5584 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
5585 This causes that any required macros inside will get before the if.
5586 * doc/autoconf.texi (autom4te.cache): A typo.
5588 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
5590 Undo previous change, except keep the change to
5591 lib/autoconf/programs.m4 that replaced grep with shell
5592 pattern-matching. This is because net-snmp configure reads stdin.
5593 Reported by Noah Misch.
5595 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
5597 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
5598 from /dev/null, as "configure" shouldn't read stdin, and this
5599 insulates us from problems (e.g., when testing for "cl").
5600 Suggested by Alexandre Duret-Lutz. Also, do this redirection
5601 before invoking "hostname" or "uname".
5602 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5603 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
5604 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
5605 "</dev/null" since it's now done at the top of 'configure'.
5606 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5607 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5608 Also, replace grep with shell pattern-matching, to save a process.
5610 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
5612 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5613 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
5614 avoid thinking that Allegro Common Lisp's "cl" command is a C++
5617 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
5619 * doc/autoconf.texi (Limitations of Usual Tools): Document that
5620 grep -q isn't portable. Improve grep -s explanation.
5621 Problem reported by Dan Manthey.
5623 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
5625 * doc/autoconf.texi (Special Shell Variables): Clarify

5776 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5777 Update the long comment explaining it.
5779 m4_require no longer writes an ``is required by'' line to the
5780 execution stack. It contains only one bit of non-redundant
5781 information: that the macro was required, not called. And even
5782 this bit is useless in most situations: have you ever met a macro
5783 which both calls and requires the same macro?
5785 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5786 (_m4_defun_pro_outer): ... only via this macro, for the outermost

5833 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
5834 Warn about newline stripping in `` and $(). Update Solaris
5836 (Limitations of Builtins): Use expr "X...", not expr "x...", as
5837 X insulates us from future changes to Posix.
5838 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline

5865 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

5891 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
5892 stored in _m4_divert_diversion or _m4_divert_dump.
5893 (m4_divert_pop): When the parameter is given, compare the symbolic
5894 name with the last diversion pushed on the stack. Previously, the
5895 current diversion was compared with the numeric value of the
5896 diversion given as the parameter.
5897 (m4_require): If the macro hasn't been expanded yet, call ...
5898 (_m4_require_call): this new macro.

6177 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
6179 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
6180 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
6181 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.

6203 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
6205 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
6206 "char c = '\200';" rather than "char c = 0x80;" as the
6207 latter doesn't conform to the strict C standard due to
6208 overflow on signed char hosts.
6210 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
6211 to -qlanglvl=ansi. We don't want to disable extensions.

6267 simplify the examples and improve their quoting.
6269 2004-11-13 Stepan Kasal <kasal@ucw.cz>
6271 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
6272 the $1_found variable, don't test whether the file is executable;

6324 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
6325 "/usr/include", clear ac_x_includes instead of leaving it as "no"
6326 (trivial change). Problem and patch reported by Andrew Church in:

6356 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
6357 texinfo.tex for now (done by hand now).
6358 * Makefile.maint (wget_files, cvs_files):
6359 Remove ansi2knr.c; nobody uses it.
6360 (ansi2knr.c-url_prefix): Remove.
6361 (cvs-update): Fix test for failure. I don't know why it ever
6364 * doc/autoconf.texi: Update URLs, some of which went stale.
6365 Use @uref rather than @href.
6367 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
6368 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
6370 * config/config.guess, config/config.sub, config/elisp-comp,
6371 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
6372 doc/fdl.texi, doc/standards.texi: Sync with master copy.

6381 tests/tools.at, tests/torture.at:
6382 Use "file name" rather than "filename" or "path",
6383 to be consistent with the terminology of the GNU coding standards.
6385 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
6387 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),

6392 More fixes to support spaces in the name of the build directory.
6393 This isn't a complete fix but it's an improvement.
6395 * bin/autoconf.as (autom4te_options): New var.
6396 Use it instead of appending to AUTOM4TE, so that we can allow
6397 spaces in the build directory's absolute name.
6398 * bin/autoheader.in ($autoconf): Allow spaces in file names.
6399 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

6413 and isnan. From a suggestion by Kevin Ryde.
6415 * lib/Autom4te/General.pm (END): Return correct exit status even
6416 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
6418 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
6420 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
6421 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
6422 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.

6430 * lib/autom4te.in (Automake-preselections): Preselect
6431 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
6433 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
6435 * lib/autom4te.in (Automake-preselections): Preselect
6436 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
6439 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
6441 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for

6448 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
6449 with pdksh, too. Problem reported by Patrick Welche via
6451 * doc/autoconf.texi (Shellology): Note that set -o posix is
6452 useful for pkdsh, too.
6454 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
6456 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
6457 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
6458 Don't fail if ENV or BASH_ENV is readonly.
6459 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
6460 etc. are read only. Problem reported by Ludovic Courtes.
6462 2004-06-23 Noah Misch <noah@cs.caltech.edu>
6464 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is

6468 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
6470 * doc/autoconf.texi (File System Conventions): Warn about
6471 names like "aux". Problem reported by Eric Blake.
6473 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
6474 by zero instead of array size, so that we can use any arithmetic
6475 constant expression (instead of requiring an integer constant
6476 expression). This allows us to test expressions like DBL_MAX <
6477 LDBL_MAX, which didn't conform to the C standard using the old
6479 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
6480 now that we can do floating-point tests at compile time.
6482 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
6484 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
6485 and LDBL_EPSILON, as the resulting expression isn't an
6486 integer constant expression and violates the C standard.
6487 Problem reported by Nelson H. F. Beebe. Also, check
6488 for "L" suffix, and check that long double doesn't have
6489 worse range or precision than double, that mixed-mode
6490 arithmetic doesn't generate a diagnostic, that double
6491 constants fit in long double.
6493 2004-06-03 Kevin Ryde <user42@zip.com.au>
6495 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
6496 malloc(0) and realloc(NULL,size).

6501 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
6503 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
6504 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
6507 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
6509 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND

6520 change). Patch reported by Ralf Wildenhues in
6521 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
6523 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
6524 function F exists if the compiler and linker let you compile an
6525 expression like (F != 0). Recent versions of GCC optimize away
6526 the reference to F in that case, since every function address must
6527 be nonzero, so the link succeeds even if F does not exist.
6528 Problem reported by Manu in
6529 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
6531 * doc/autoconf.texi (Systemology): Standardize on the spelling of
6532 "Unix". Many uses changed.
6533 (Limitations of Builtins): Explain better why the ! command isn't

6539 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
6541 2004-05-19 Kevin Ryde <user42@zip.com.au>
6543 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
6544 referencing AC_FUNC_STRERROR_R.
6546 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
6547 note pessimistic assumption when cross compiling.
6549 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
6551 * doc/autoconf.texi (Limitations of Make): Note that BSD make
6552 (until 2004) invoked subcommands with sh -e, contra POSIX.
6553 Reported by Kevin Ryde.
6555 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
6557 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
6558 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
6559 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
6560 `test -f " /usr/bin/grep"', which _always_ failed.
6561 (AC_PROG_SED): Ditto bogus PATH fix.
6562 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
6563 requires that grep correctly supports _multiple_ `-e' options, rather
6564 than stating only that grep should accept `-e'.
6566 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
6568 Port to C99, which requires that 'exit' be declared.
6570 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
6571 to ensure that stdlib.h is included.
6572 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
6573 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
6574 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
6575 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
6576 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
6577 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
6578 when using 'exit' in a test; C99 requires that 'exit' be declared.
6580 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
6582 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
6583 now prefers 'grep' implementations that accept -e.
6584 (Limitations of Usual Tools): Describe problems of traditional
6585 egrep and fgrep with long input lines, and of traditional grep
6587 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
6588 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
6589 All callers changed. Append /usr/xpg4/bin to the PATH, for
6591 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
6592 the user with complaints about multiple -e options.
6593 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
6594 Define it with AC_PROG_GREP.
6595 * configure.ac (AC_PROG_GREP): Add.
6596 * lib/freeze.mk (GREP): New macro.
6598 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
6600 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
6601 a possible candidate only after all others fail, rather than
6602 consulting it first. This improves backward compatibility by
6603 better reflecting the way shell selection occurred in previous
6604 versions of Autoconf, and should help to avoid triggering latent
6605 problems in other packages, such as the one in Automake where zsh
6606 is not handled robustly:
6607 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
6608 Although it is not Autoconf's responsibility to work around
6609 problems in Automake, it nevertheless makes sense to avoid
6610 introducing unnecessary incompatibilites.
6612 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
6613 Gary V. Vaughan <gary@gnu.org>
6615 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
6616 how deeply nested we are when a suitable tool is found, set the
6617 ac_path_TOOL_found flag.
6618 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
6619 nested we are in this macro. Break out of all 3 nested loops if
6620 ac_path_TOOL_found is set.
6622 2004-04-21 Gary V. Vaughan <gary@gnu.org>
6624 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
6625 of the _AS_PATH_WALK loop too if GNU flavor is found.
6627 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
6629 * doc/autoconf.texi (Limitations of Make): Update documentation
6630 for `$<'. New entry `Long lines', based on a report from Simon
6631 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
6632 paragraph about DJGPP, based on a mail from Richard Dawe.
6634 2004-04-20 Paul Eggert <eggert@twinsun.com>
6636 * tests/c.at (C keywords): Don't assume that GCC supports
6637 "restrict" and "inline", as sufficiently-old GCC versions do not
6638 (also, GCC configured to be in pedantic C89 mode does not).
6639 Problem reported by Sumit Pandya in:
6640 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
6642 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
6643 consider -g to work if it generates warnings when plain compiles
6644 don't. Problem reported by Braden McDaniel in:
6645 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
6647 * doc/autoconf.texi (Slashes): New section, to document a problem

6651 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
6652 linker output files before linking, to work around IRIX 6 linker bug.
6653 Problem reported by Rainer Orth in:
6654 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
6656 2004-04-20 Gary V. Vaughan <gary@gnu.org>
6658 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
6659 best tool so far counter rely on the tool path variable name to
6660 avoid checks for one tool being affected by the results of running
6661 the length check on a previous tool.
6663 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
6664 match expression argument, as different greps have different
6665 regular expression flavours.
6666 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
6668 (AC_PROG_EGREP): Pass 'EGREP$'.
6669 (AC_PROG_GREP): Pass 'GREP$'.
6671 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
6673 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
6674 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.

6678 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
6679 Types, Specific Compiler Characteristics, System Services,
6680 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
6681 etc. consistently instead of 'long', 'short', 'unsigned' etc.
6682 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
6683 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

6694 2004-03-28 Paul Eggert <eggert@twinsun.com>
6696 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
6697 now defines HAVE_DECL_TZNAME if it is declared, when
6698 HAVE_STRUCT_TM_TM_ZONE is not defined.
6699 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
6700 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

6707 thanks to Paul Eggert.
6709 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
6711 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
6712 Fortran compiler is ifort, also added pghpf; thanks to Nelson
6713 H. F. Beebe for the bug report.
6715 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
6717 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
6718 quoted -cmdline argument in Portland Group compiler (bug
6719 reported by Jeffrey J. Barteet).

6748 * tests/mktests.sh: Do not generate tests for the
6750 * NEWS: Document these changes.
6752 * doc/autoconf.texi: Avoid macros with unbraced arguments,
6753 they make TeX hang up.

6769 * bin/Makefile.am (edit): Don't use $< in a context where
6770 POSIX doesn't require support for it. Use $@.in instead.
6771 Problem reported by Anthony N. Frasso in
6772 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
6773 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.

6777 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
6778 from the next generation of Libtool.
6779 * lib/autom4te.in (Autoreconf-preselections): Ditto.
6781 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6783 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
6784 is not always thread-safe. Report from Nathanael Nerode.
6786 2004-02-18 Paul Eggert <eggert@twinsun.com>
6788 Fix a dependencies problem, stemming from a Autoconf 2.59 build
6789 problem on QNX reported by Stephen Rasku in
6790 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
6792 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
6793 $(m4sh_m4f_dependencies); this removes a FIXME.
6794 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
6795 (MAINTAINERCLEANFILES): Split into pieces,
6796 one per related section. Add $(srcdir)/wrapper.in.
6798 2004-02-09 Paul Eggert <eggert@twinsun.com>
6800 * doc/autoconf.texi (Setting Output Variables): Emphasize that
6801 AC_SUBST provides no portable way to escape literal newlines.
6803 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6804 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6805 Darwin uses -lcrt2.o and there's little point to cataloging all
6806 the system variants. Partial fix reported by Andreas Waechter in:
6807 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

6823 the behavior of the third argument.
6824 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
6825 correctly the behavior of the third argument. Document
6826 what the three macros that AU_DEFUN defines do. Fix
6827 warning message when the third argument includes $0

6880 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
6882 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
6883 2003 (except 1997) to the list of copyright years. This undoes
6884 the 2003-05-22 change, which removed the older years from the list.
6885 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

6896 egrep and fgrep respectively if $GREP -E/-F don't work.
6897 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
6898 _AC_PROG_GREP, and AC_PROG_SED.

6929 2004-01-26 Paul Eggert <eggert@twinsun.com>
6931 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6932 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6933 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6934 not <inttypes.h>. Problem reported by Tim Mooney in
6935 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6936 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6939 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6940 otherwise "make check" fails because it forbids cmp (I guess
6941 because cmp treats files as binary on DOS-like systems).
6943 * tests/mktests.sh: Update copyright date to 2004, since some tests
6944 have changed in 2004.
6946 2004-01-23 Gary V. Vaughan <gary@gnu.org>
6948 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
6949 non-truncating sed or gsed program in PATH.

6951 * doc/autoconf.texi (Particular Programs): Document it.
6954 2004-01-15 Paul Eggert <eggert@twinsun.com>
6956 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6957 -std1 disables some useful extensions on Tru64. Problem reported
6959 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6961 2004-01-14 Paul Eggert <eggert@twinsun.com>
6963 * doc/autoconf.texi (Programming in M4sh): Document that
6964 AS_MKDIR_P succeeds if the destination is a symbolic link
6965 to an existing directory.
6966 (Limitations of Usual Tools): Note that mkdir -p might not
6967 succeed on symlinks to directories.
6969 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6971 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

6981 2004-01-10 Jim Meyering <jim@meyering.net>
6983 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6985 2004-01-09 Paul Eggert <eggert@twinsun.com>
6987 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6988 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6989 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6990 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6991 AC_COMPILE_IFELSE, since we now assume our caller invokes
6992 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6993 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6994 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6995 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.

7523 * bin/Makefile.am (edit): Handle '@configure_input@'.
7524 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
7525 (ifnames): chmod -w.
7526 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
7527 executables, not bin/ executables! Otherwise all the magic needed
7528 to find non installed files is turned off. This caused a failure
7529 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
7530 as found in its environment (sent by tests/autoreconf): pointing
7531 to bin/autom4te that could not find its files.
7532 * tests/mktests.sh: Force the replacement of generated files, for
7533 the sake of "mv" program that are interactive when overwriting a

7611 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.

7624 2003-09-04 Akim Demaille <akim@epita.fr>
7626 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
7628 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
7630 Add support for newer Fortran dialects. The F77 interface is
7631 unchanged, and continues to support Fortran 77. New FC macros
7632 correspond to all the old F77 macros, with output variables FC,
7633 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
7634 available dialect, but older dialects can be specified. There are
7635 new macros AC_FC_SRCEXT to set the source extension, and
7636 AC_FC_FREEFORM to accept free-form source files.

7758 ($help): Use Autom4te::ChannelDefs::usage.
7759 * bin/autoscan.in: Use Autom4te::ChannelDefs.
7760 * lib/Autom4te/General.pm: Don't export error: you don't own it.
7762 2003-08-21 Akim Demaille <akim@epita.fr>
7764 First stab at preserving warnings between calls to autom4te,
7765 including when the cache is used.
7767 There are still several issues: (i) there are too many runs of m4
7768 (one for include, one for warnings, and some more), (ii) warnings
7769 spreading on several lines are not handled gracefully, (iii) the
7770 code meant to have the call stack display for errors does not work
7771 (its handling should move from m4 to autom4te).
7773 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7775 (@preselect): Add m4_warn.
7776 ($exit_status): Remove, use $exit_code.
7777 ($help): Use Autom4te::ChannelDefs::usage.
7778 (&handle_m4): No longer define the m4_warnings.
7779 At each run, extract and report the warnings.
7780 Always cache the result, including if the exit status is on
7781 failure, since if nothing changes, we should result in the same
7782 failure, hence we can use the cache.
7783 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7784 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7786 (m4_warn): Redefine as a do-nothing: it is its invocation that
7787 matters, as warnings are now reported via traces.
7788 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7789 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7790 the latter reveals calls to the former.
7794 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
7796 2003-08-21 Akim Demaille <akim@epita.fr>
7798 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

7806 (&parse_warnings): Accept a list of warning requests.
7807 (&usage): Return a string, not a side effect.
7808 (cross): New warning category.

7817 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
7818 * bin/autoscan.in: Adjust.
7820 2003-08-20 Akim Demaille <akim@epita.fr>
7822 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
7823 Reported by Alexandre Duret-Lutz.
7825 2003-08-20 Akim Demaille <akim@epita.fr>
7827 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7828 * bin/autom4te: Adjust.
7829 In particular, be Autoconf tools are really silent when properly
7830 working, bind the verbosity of the 'note' channel to $verbose.
7831 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
7832 (&xsystem, &contents): Remove, since they are exported by...
7833 * lib/Autom4te/FileUtils.pm: this.

7956 not all of them. This fixes 1. the fact that when testing
7957 Autoconf there are many many config.log, 2. the incorrect use of
7958 top_srcdir to find config.log.
7959 Don't mix the detailed output of failed test with the summary of

8021 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
8022 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
8023 (AT_INIT): Support for expected failures.
8025 2003-06-02 Akim Demaille <akim@epita.fr>
8027 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
8029 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
8030 Autoconf nor Automake.
8031 (&contents): New, from Automake.
8034 2003-05-28 Paul Eggert <eggert@twinsun.com>
8036 * NEWS, doc/autoconf.texi (Particular Functions),
8037 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
8038 is the inverse of localtime.
8040 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
8042 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
8043 (handle_exec_errors): New function. Work around $! being
8044 altered by WEXITSTATUS.
8045 (xqx, xsystem): Use handle_exec_errors.
8047 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
8049 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
8050 Do not call `_exit()', simply modify `$?'.
8051 (xsystem): Reset $! before running system, and check it afterward.
8052 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
8053 63 for version mismatches.
8055 2003-05-23 Akim Demaille <akim@epita.fr>
8057 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
8058 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
8059 the middle of a line).
8060 * lib/m4sugar/m4sugar.m4: Likewise.
8061 Remove useless spaces in comments.
8063 2003-05-23 Akim Demaille <akim@epita.fr>
8065 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
8066 exit 63, so that we (or Automake's "missing") can tell the
8067 difference with a plain failure.
8068 * doc/autoconf.texi (Notices): Adjust.
8070 2003-05-23 Akim Demaille <akim@epita.fr>
8072 * Makefile.am, bin/Makefile.am, config/Makefile.am,
8073 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:

8076 2003-05-22 Jim Meyering <jim@meyering.net>
8077 Paul Eggert <eggert@twinsun.com>
8079 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
8080 Remove `#include <stdlib.h>' from the list; we should never
8081 make confdefs.h include <stdlib.h> or <cstdlib>, because the
8082 resulting namespace pollution would cause other tests to fail.
8083 Configure scripts run with some older versions of g++ and HP's
8084 aCC would fail due to such an #include. Problems reported by
8085 Matthew Mueller in <http://bugs.debian.org/120704> and by
8087 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
8088 In the test, use the test declaration before including <stdlib.h>,
8089 as that's closer to how it'll be used.
8091 2003-05-23 Akim Demaille <akim@epita.fr>
8093 * doc/autoconf.texi (Header Portability): ucred.h.
8096 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8098 Overhaul Autotest's logging: generate separate log files
8099 in testsuite.dir/NNN/testsuite.log, and append them to
8100 testsuite.log instead of re-running the test verbosely.
8102 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
8103 file descriptor, write 0 to at_status_file instead of setting
8104 at_status=0, initialize some new variables (at_status_file,
8105 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
8106 to rerun the tests, instead append the at_group_log to the
8107 at_suite_log when a test fails.
8108 (AT_SETUP): pipe the test case's output into at_tee_pipe,
8109 with the AS_MESSAGE_LOG_FD redirected to stdout.
8110 (AT_CLEANUP): save the output status in $at_status_file
8111 and restore it, redirect the AS_MESSAGE_LOG_FD back to
8113 (AT_CHECK): since tests are run with a redirected stdout,
8114 and used to be re-run in verbose mode, turn some $at_verbose
8115 into echo, and don't redirect the output of testing stdout
8118 * lib/autotest/autoconf.texi (testsuite Scripts): Update
8119 the name of the debugging directory and information about
8122 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

8156 2003-05-22 Akim Demaille <akim@epita.fr>
8158 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

8195 Reported by Sander Niemeijer.
8196 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.

8234 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
8236 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
8239 2003-05-06 Akim Demaille <akim@epita.fr>
8241 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
8242 longer updates aclocal.m4 if useless, (ii) if a file m4_included
8243 by aclocal.m4 is changed it might require the importing of another
8244 m4 extension file, i.e., aclocal must be run.
8246 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
8247 (&parse_args): Use --force with aclocal if required and supported.
8248 (&autoreconf_current_directory): Use &run_aclocal.
8250 2003-05-06 Akim Demaille <akim@epita.fr>
8252 Lock autom4te's cache.
8254 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
8255 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
8256 argument instead of a file name, so that the request file remains
8257 open during the whole autom4te run.
8258 ($icache_file): New.
8259 (&freeze): Lock the $icache_file.
8261 2003-04-29 Derek Price <derek@ximbiot.com>
8263 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
8264 seperator with m4_append_uniq(). It doesn't work.
8265 (AT_CLEANUP): Add `;' to end of at_help_all.
8266 (AT_INIT): Allow --keywords to be specified more than once. When
8267 grepping $at_help_all for keywords, use the field and keyword
8268 seperators to ensure a complete keyword match. Alter at_prev handling
8269 to support the new --keywords behavior.
8271 2003-04-27 Karl Berry <karl@freefriends.org>
8273 * doc/autoconf.texi: Make the dir entries in the autoconf manual
8274 align better with others. I also made some of the individual
8275 entries on one line, for brevity and to make it easier for me to
8276 sort my dir-example file in the Texinfo distribution :).
8278 2003-04-12 Jim Meyering <jim@meyering.net>

8333 2003-03-29 Akim Demaille <akim@epita.fr>
8335 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The

8337 Suggested by Paul Eggert.
8339 2003-03-28 Akim Demaille <akim@epita.fr>
8341 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
8342 reading the section "Present But Cannot Be Compiled" when the
8343 header causes problems.
8345 2003-03-28 Akim Demaille <akim@epita.fr>
8347 * tests/torture.at (Configuring subdirectories): Require aclocal
8348 1.4, otherwise the test fails, as it does support configure.ac.
8349 This fixes the "test 40 failed" bug reports.
8351 2003-03-28 Akim Demaille <akim@epita.fr>
8353 * doc/autoconf.texi (C Compiler): `#line' portability.

8363 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
8364 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
8365 use new diversions in preparation for accepting new arguments and
8366 allowing scripting around tests.
8367 (OPTIONS,TAIL): Remove these diversions to make way for the ones above.
8369 2003-03-26 Derek Price <derek@ximbiot.com>

8419 about `$<' in inference rules, it was a bogus interpretation of
8420 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
8421 Tru64 make in the "target lookup" section.
8422 (Automake): Automake 1.5+ no longer requires special tools to be
8423 present on the developer's host.

8451 2003-02-25 Pavel Roskin <proski@gnu.org>
8453 * bin/autoheader.in: Add missing newline when printing

8469 format starting with "-".
8471 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>

8474 is not portable inside Makefile.
8476 2003-02-20 Akim Demaille <akim@epita.fr>
8478 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
8479 compiler says yeah, but preproc says nope, compiler is right.
8480 Conversely, prompt the reader to send a bug report to the
8481 maintainers of the package, not of Autoconf.
8483 2003-02-20 Klee Dienes <kdienes@apple.com>
8485 * bin/autoreconf.in (autoreconf_current_directory): Properly

8496 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
8497 innocuous variant befor including <limits.h> or <assert.h>. This
8498 works around a bug reported by Albert Chin: HP-UX 11i
8499 (and earlier versions) have a <limits.h> that declares
8500 gettimeofday and many other functions.
8502 2002-12-03 Paul Eggert <eggert@twinsun.com>
8506 * NEWS, configure.ac: Update version.
8508 * doc/fdl.texi: Upgrade to FDL version 1.2.
8510 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
8511 nontrivially in main's body, so that f's external declaration is
8512 not optimized away in AIX. This should fix the bug reported by
8514 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
8516 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
8517 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
8518 defined, to support freestanding compilers. This should fix the
8519 bug reported by Momchil Velkov in
8520 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
8522 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
8523 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

8558 * Makefile.maint: Sync with Bison, i.e.:
8559 (po-check): Scan .l and .y files instead of the
8560 .c and the .h files that they generate. This fixes the bug
8561 reported by Tim Van Holder in:

8584 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q

8622 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
8624 We _have_ to stop using the old compatibility scheme that tried to
8625 avoid useless backslashes because Libtool 1.4.3 contains a
8626 AC_DEFINE([error_t], [int],
8627 [Define to a type to use for \`error_t' if it is not
8628 otherwise available.])
8629 We _have_ to quote the single quote and backslashes with \. The
8630 old compatibility scheme saw that ` was backslashed, and therefore
8631 did not quote the single quote. Hence before this patch, Autoconf
8632 was not compatible with Libtool.

9050 autoheader's quiet mode.
9051 (AT_CHECK_AUTOUPDATE): Likewise.
9052 * tests/tools.at (autoupdate): Adjust.
9053 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
9055 2002-10-11 Akim Demaille <akim@epita.fr>
9057 No longer use CPP to check for the existing of headers: use CC to
9058 check for compilability.
9060 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
9061 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
9062 (_AC_CHECK_HEADER_NEW): Rename as...
9063 (AC_CHECK_HEADER): this.
9065 * lib/autotest/general.m4 (AT_INIT): Include the failed test
9066 numbers in the Subject suggestion.
9068 2002-10-11 Akim Demaille <akim@epita.fr>
9070 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
9071 Suggest using AC_CHECK_DECLS instead.
9073 2002-10-11 Akim Demaille <akim@epita.fr>
9075 * tests/torture.at (AC_ARG_VAR): Have configure report the value
9078 2002-10-11 Akim Demaille <akim@epita.fr>
9080 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
9081 file name to enable parallel executions.
9082 From Sam Varshavchik.
9084 2002-10-08 Akim Demaille <akim@epita.fr>
9086 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
9087 aclocal invocation, as Gettext macros might not be visible to
9089 Instead of blindly running autopoint, scan configure.ac (not the
9090 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
9091 Reported by Paul D. Smith.
9093 2002-10-08 Paul Eggert <eggert@twinsun.com>
9095 Work around problems found when POSIXLY_CORRECT=1 is set.
9096 None of this seems to have anything to do with POSIX, really,
9097 but it's how Perl getopt works.
9098 * bin/autom4te.in (parse_args): Configure GetOpt with
9100 * doc/autoconf.texi (Invoking autom4te):
9101 --warning -> --warnings.
9102 * lib/autom4te.in: --warning -> --warnings.
9104 2002-09-28 Akim Demaille <akim@epita.fr>
9106 * doc/autoconf.texi (autom4te.cache): New section.
9108 2002-09-28 Akim Demaille <akim@epita.fr>
9110 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
9111 (Automake-preselections): Update.
9112 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
9114 2002-09-28 Akim Demaille <akim@epita.fr>

9118 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9119 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
9121 2002-09-28 Akim Demaille <akim@epita.fr>
9123 * tests/torture.at (Configuring subdirectories): Be robust to
9124 users who use config.site to require for a cache: in this case,
9125 the two last configure runs, using two different sets of
9126 arguments, trigger a legitimate error.
9128 2002-09-28 Akim Demaille <akim@epita.fr>
9130 * tests/m4sh.at (Functions Support, Functions and return Support):
9133 2002-09-28 Akim Demaille <akim@epita.fr>
9135 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
9136 autoheader are Perl programs.

9147 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
9148 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
9149 * lib/autoconf/programs.m4: here.

9158 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
9159 that were listed in the original autoscan.list.
9160 * lib/autoconf/headers.m4: Similarly with headers.
9161 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
9162 (.m4.m4f): Don't pass --prepend-include, since that's done by
9163 tests/autom4te itself.
9164 * lib/autoscan/Makefile.am: Include freeze.mk.
9165 (autoscan.list): New target --this file is no longer a source.
9166 (autoscan.pre): New file.
9168 2002-09-28 Akim Demaille <akim@epita.fr>
9170 * bin/autoscan.in (@kinds): Make them singular.
9172 (&init_tables): When --debug, report the list of rules to ease
9173 tracking changes in autoscan.list.
9174 * lib/autoscan/autoscan.list (function): Strip comments, sort.
9176 2002-09-28 Akim Demaille <akim@epita.fr>
9178 * lib/autoscan/functions, lib/autoscan/headers,
9179 * lib/autoscan/identifiers, lib/autoscan/makevars,
9180 * lib/autoscan/programs: Merge into...
9181 * lib/autoscan/autoscan.list: this.
9182 * bin/autoscan.in (&init_tables): Adjust.
9184 2002-09-28 Akim Demaille <akim@epita.fr>
9186 * lib/autoscan/functions, lib/autoscan/headers,
9187 * lib/autoscan/identifiers, lib/autoscan/makevars,
9188 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
9189 `functions' line is now prefixed with `function:'.
9190 * bin/autoscan.in (&init_tables): Adjust.
9192 2002-09-28 Akim Demaille <akim@epita.fr>
9194 From now on, autoscan files must always map a macro name to a
9195 word: there is no `default' macro for autoscan.
9197 * bin/autoscan.in (&init_tables): Reject entries with no macro at
9199 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
9202 2002-09-28 Akim Demaille <akim@epita.fr>
9204 * bin/autoscan.in (%c_keywords): Remove.
9205 (&used): Keep only track of the words we might be interested in.
9206 (&output_kind): It is no longer needed to look for non active
9209 2002-09-27 Akim Demaille <akim@epita.fr>

9212 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
9213 * lib/autoscan/functions: Adjust.
9214 * doc/autoconf.texi (Particular Functions): Adjust.
9216 2002-09-27 Akim Demaille <akim@epita.fr>
9218 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
9220 Thanks to Bill Moseley and Paul Eggert.
9221 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
9222 the tmpdir must be created.
9223 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
9224 dir be in the build tree, instead of $TMPDIR.
9226 2002-09-27 Akim Demaille <akim@epita.fr>
9228 * bin/autoscan.in: Improve the comments.
9229 (&parse_args): Drop obsolete undocumented options.
9230 (&output_kind): Output warnings.
9231 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
9232 (getwd): Trigger a warning.
9234 2002-09-26 Akim Demaille <akim@epita.fr>
9236 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
9237 Reported by Ralf Corsepius.
9238 * doc/autoconf.texi (autoreconf Invocation): Likewise.
9240 2002-09-26 Akim Demaille <akim@epita.fr>
9242 Single suffix rules and seperated dependencies are not portable.
9244 * doc/autoconf.texi (Installation Directory Variables): Update.
9245 (Limitations of Make): Some about `Single Suffix Rules and
9246 Separated Dependencies'.
9247 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9248 (ifnames, autoscan, autom4te): Un-factor into several rules.
9250 2002-09-25 Paul Eggert <eggert@twinsun.com>
9252 * BUGS (Interoperability bugs): New section. Mention libtool
9253 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
9255 2002-09-24 Paul Eggert <eggert@twinsun.com>
9257 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
9258 make handles suffix-rules differently from GNU make.
9260 * bin/Makefile.am (SUFFIXES, .in): Remove.
9261 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
9262 Move the body of the old .in rule here.
9264 2002-09-16 Akim Demaille <akim@epita.fr>
9266 i960 compilers create `b.out' files by default.
9267 Reported by Ralf Corsepius.
9269 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
9270 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
9272 2002-09-13 Paul Eggert <eggert@twinsun.com>
9274 * doc/autoconf.texi (Particular Headers): Remove obsolete
9275 reference to `struct timezone' in the description of
9278 2002-09-13 Akim Demaille <akim@epita.fr>
9282 * config/config.sub, config/config.guess: Update.
9283 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
9284 * Makefile.am: Adjust.
9286 2002-09-13 Akim Demaille <akim@epita.fr>
9288 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
9289 reading config.log when the compiler is rejected.
9290 Suggested by Guido Draheim.
9292 2002-09-13 Akim Demaille <akim@epita.fr>
9294 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
9295 (chdir_init) might hang when stat'ing mounted directories.
9296 Reported by Vance Shipley.
9298 2002-09-12 Akim Demaille <akim@epita.fr>
9300 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
9303 2002-09-12 Akim Demaille <akim@epita.fr>
9305 * doc/autoconf.texi (Defining Symbols): Present two different
9306 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
9307 difference between 1 argument calls, and 2-3 argument calls.
9309 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
9311 * doc/autoconf.texi: Review grammar and punctuation.
9313 2002-09-11 Paul Eggert <eggert@twinsun.com>
9315 * doc/autoconf.texi: Fix minor formatting, spelling, and
9317 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
9318 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
9321 2002-09-11 Akim Demaille <akim@epita.fr>
9323 * doc/autoconf.texi (Questions): Rename as...
9325 (Defining Directories): New.
9327 2002-09-09 Akim Demaille <akim@epita.fr>
9329 * doc/autoconf.texi (Making testsuite Scripts): Update.
9330 Suggested by Nishio Futoshi.
9332 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
9334 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
9335 plain `@' is wanted.
9337 2002-09-09 Akim Demaille <akim@epita.fr>
9339 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
9340 `duplicates', since the algorithm was too naive and could keep
9341 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
9342 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
9343 Reported by Ralf Corsepius.
9344 * tests/torture.at (Configuring subdirectories): Exercise these
9347 2002-09-09 Akim Demaille <akim@epita.fr>
9349 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
9350 looking for a replacement file.
9351 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
9352 directory is relative.
9353 * doc/autoconf.texi (Generic Functions): Clarify the replacement
9354 directory definition.
9355 Reported by Andreas Schwab and Jim Meyering.
9357 2002-09-06 Akim Demaille <akim@epita.fr>
9359 * doc/autoconf.texi (Setting Output Variables): Clarify what
9360 precious variables are.
9361 Suggested by Pontus Skoeld.
9363 2002-09-05 Akim Demaille <akim@epita.fr>
9365 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9366 (ifnames, autoscan, autom4te): Since we don't only depend on
9367 configure.ac variables (such as VERSION etc.), but also on prefix
9368 and so forth, depend on Makefile, not configure.ac.
9369 Reported by Alexandre Duret-Lutz.
9370 * doc/autoconf.texi (Installation Directory Variables): Adjust.
9372 2002-09-05 Kevin Ryde <user42@zip.com.au>
9374 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
9375 doesn't seem to be confined to ia64, just say "some versions".
9377 2002-09-04 Akim Demaille <akim@epita.fr>
9379 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
9381 * Makefile.am (maintainer-clean-local): Remove.
9382 (MAINTAINERCLEANFILES): Remove COPYING.
9384 2002-09-03 Paul Eggert <eggert@twinsun.com>
9386 * doc/autoconf.texi (Configuration Commands): Remove obsolete
9387 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
9390 2002-09-03 Akim Demaille <akim@epita.fr>
9392 * configure.ac: Bump to 2.53d.
9393 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
9394 as of today, on Automake's team suggestion.
9396 2002-09-03 Akim Demaille <akim@epita.fr>
9400 2002-09-02 Akim Demaille <akim@epita.fr>
9402 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
9404 * configure.ac: Disable SITE_MACRO_DIR.
9406 2002-09-02 Jim Meyering <meyering@lucent.com>
9408 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
9409 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
9410 Also, tweak grammar: s/make sure to/be sure to/.
9412 2002-09-02 Paul Eggert <eggert@twinsun.com>
9414 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
9415 directory names are generally preferable to physical names.
9417 2002-09-02 Akim Demaille <akim@epita.fr>
9419 * lib/Autom4te/General.pm (&update_file): s/die/error/.
9420 Reported by Raja R. Harinath.
9421 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
9422 * bin/autoupdate.in: Use error instead of die.
9424 2002-09-01 Paul Eggert <eggert@twinsun.com>
9426 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
9427 ordinary shell concatenation rather than echo+tr+sed command that
9428 runs afoul of a long-line-related sed bug in Solaris 8.
9430 * bin/autoheader.in (parse_args): --warning -> --warnings.
9432 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
9433 stdout, as traditional "ls" does.
9434 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
9435 _AC_COMPILER_EXEEXT_O): Likewise.
9436 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
9438 * bin/autoconf.as: Add --prepend-include option. This patch was
9439 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
9440 but bin/autoconf.in is generated automatically from bin/autoconf.as.
9442 * bin/autoconf.in, configure: Regenerate.
9444 * doc/autoconf.texi (Special Shell Variables): Mention
9445 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
9447 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
9448 MAILPATH and set PS1, PS2, PS4 to default values, to work
9449 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
9450 For LC_ALL etc, first try to set to "C" as POSIX requires and as
9451 the Autoconf documentation specifies; fall back to "unset" only if
9452 this fails. Use a shell for-loop for this rather than an m4 loop,
9453 to shorten the output script.
9455 2002-08-30 Paul Eggert <eggert@twinsun.com>
9457 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
9458 1003.1-2001's requirements for CDPATH. Give a simpler workaround
9459 for the CDPATH problem. Document PWD.
9460 (Limitations of Builtins): Document the problem that "cd $foo" and
9461 "ls $foo" may refer to different directories in shells conforming
9462 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
9463 example, since the old example is now out of date.
9465 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
9466 FOO" and "ls FOO" talk about different directories; this catches
9467 problems when POSIX 1003.1-2001 "cd" fails due to symlink
9470 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
9471 of rolling our own unset.
9472 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
9473 in practice we needn't worry about CDPATH if unset doesn't work.
9475 * Makefile.in, aclocal.m4, bin/Makefile.in,
9476 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
9477 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
9478 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
9479 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
9480 tests/Makefile.in: Regenerate with Automake 1.6.3.
9482 * config/config.guess, config/config.sub, config/mkinstalldirs:
9485 * configure: Regenerate with self.
9487 2002-08-30 Kevin Ryde <user42@zip.com.au>
9489 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
9492 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
9494 * bin/autom4te.in (Request::load): Correctly test for "do" read
9497 2002-08-29 Akim Demaille <akim@epita.fr>
9499 * lib/Autom4te/General.pm (&xqx): New.
9500 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
9501 hand, which is not portable.
9503 * bin/autom4te.in: Use them.
9504 Use &error instead of die.
9505 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
9508 2002-08-17 Paul Eggert <eggert@twinsun.com>
9510 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
9511 default list of compilers to try, since it was long ago superseded
9512 by the ksh fc builtin. Suggested by Steven G. Johnson.
9514 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
9516 * doc/autoconf.texi (Invoking autom4te): End the option table,
9517 fixing a bug introduced by the previous patch.
9518 (Limitations of Make): Add a 'target lookup' subentry in the
9519 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
9521 2002-07-29 Mark D. Roth <roth@feep.net>
9523 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
9524 options and use $AUTOM4TE_PATH.
9525 * doc/autoconf.texi: Remove documentation of autom4te
9526 --include-envvar and --site-macro-subdir options and document
9527 use of $AUTOM4TE_PATH.
9528 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
9529 arguments from each language section.
9531 2002-07-29 Paul Eggert <eggert@twinsun.com>
9533 * doc/install.texi: Include copyright symbol in copyright notice.
9535 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
9537 (AM_MAKEINFOFLAGS): New macro.
9538 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
9539 * Makefile.am (INSTALL): Use the new macros.
9540 Use -o rather than --output, since "missing" does not grok --output.
9542 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9544 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
9545 comments do not always work. Never trust the exit status of
9548 2002-07-24 Kevin Ryde <user42@zip.com.au>
9550 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
9551 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
9553 2002-07-23 Paul Eggert <eggert@twinsun.com>
9555 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
9556 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
9557 apparently treats PATH="nonexistent" as if it contained ".".

9830 2002-05-16 Paul Eggert <eggert@twinsun.com>
9832 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9833 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9834 Both macros now accept an optional source-dir arg.
9835 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9837 * NEWS: Document this.
9838 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9840 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9841 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,

9853 and it causes a 'test' syntax error if it fails.
9854 Bug reported by Stephen Gildea.
9856 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9857 If prototypes are supported, use them to check this at compile-time,
9858 instead of trying to check it at run-time. If we must do a run-time
9859 check, assume that setvbuf is standard when cross-compiling, as
9860 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9861 Bug reported by Paul D. Smith.
9863 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9864 argument specifying location of getloadavg.c. This removes a
9865 FIXME. This idea was taken from Jim Meyering's implementation in
9867 * doc/autoconf.texi (Particular Functions): Document this.
9868 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9869 that's what the code does; this fixes a bug reported by

9874 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9875 autopoint instead of gettextize.
9876 ($uses_alocal): Rename as...
9877 ($uses_aclocal): this.

9887 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9888 files to be 1 second older; just set them to be the same time.
9889 Also, sleep 1 second after the first aclocal, to work around
9890 problems with sub-second time stamps on the input files.
9892 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9894 * doc/autoconf.texi: Mention "set -e -x" lossage

9903 2002-04-29 Akim Demaille <akim@epita.fr>
9905 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9906 of lack of $LINENO support, then the test will compare the $LINENO
9907 in testsuite vs. the lineno in the test file. This is wrong, of
9909 Be sure to protect it.
9910 Reported by Patrick Welche.

9914 * doc/autoconf.texi (Obsolete Macros): Typo.
9915 Reported by Vladimir Volovich.
9917 2002-04-25 Akim Demaille <akim@epita.fr>
9919 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9920 than some of the input files, hence, on the second run of aclocal,
9921 if some of its input are younger, make them older.
9922 Suggested by Paul Eggert.
9924 2002-04-25 Akim Demaille <akim@epita.fr>
9926 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

9936 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9937 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the

9946 config.h.in that was to be created.
9948 2002-04-23 Akim Demaille <akim@epita.fr>

10060 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
10061 * lib/autotest/general.m4 (AT_INIT): Likewise.
10062 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10063 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
10066 Use this M4sh to generate Autoconf's shell scripts.
10068 * tests/wrapsh.as: New, precursor of wrapsh.in.
10069 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
10070 on Autotest and M4sh.
10071 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
10072 (wrapsh.in): New target.
10073 * bin/autoconf.as: New, precursor of autoconf.in.
10074 (autoconf.in): New target.
10076 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

10079 with indented comments in rules.

10095 Reported by Ezra Peisach.
10097 2002-04-04 Andreas Schwab <schwab@suse.de>
10099 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
10100 contains no literal separators.
10102 2002-04-03 Akim Demaille <akim@epita.fr>
10104 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
10105 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
10106 Use dnl, not the KILL diversion.
10108 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
10109 (AC_CONFIG_LINKS): here.
10111 Don't use the KILL diversion, as it kills spurious output, which
10112 results in failures being hidden.
10113 Use m4_defn where appropriate.
10114 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
10115 after the second argument.
10117 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
10118 syntax, as it is provided by M4sugar.
10119 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
10121 2002-04-03 Andreas Schwab <schwab@suse.de>
10123 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
10124 expanded if $# <= 2.
10126 * bin/autoreconf.in (autoreconf): Run automake after rerunning
10129 2002-04-03 Akim Demaille <akim@epita.fr>
10131 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)

10134 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
10135 (_AC_COMPILER_OBJEXT): Use them.
10136 Fixes Debian #138666.
10138 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
10140 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
10142 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
10143 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
10144 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
10145 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
10146 (AC_C_CONST): Same.
10147 (AC_C_INLINE): Same.
10148 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.

10156 _AS_MKDIR_P_PREPARE.
10158 2002-03-28 Kevin Ryde <user42@zip.com.au>
10160 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
10161 to avoid versions of HP C which don't allow that.
10163 2002-03-27 Paul Eggert <eggert@twinsun.com>
10165 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
10166 (AS_SHELL_SANITIZE): Invoke it.
10167 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

10171 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
10173 2002-03-26 Akim Demaille <akim@epita.fr>
10175 * doc/autoconf.texi (Introduction): The GNATS base moved.
10177 2002-03-25 Paul Eggert <eggert@twinsun.com>
10179 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
10180 as POSIX requires, as it doesn't work with Zsh.
10181 * doc/autoconf.texi (Assignments): Document the problem.
10183 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
10185 * doc/autoconf.texi (Limitations of Make): Mention more issue
10186 about VPATH, overriding of macros in sub-makes, and handling of
10189 2002-03-21 Paul Eggert <eggert@twinsun.com>
10191 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
10192 problem with here-document buffer boundaries.
10194 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
10195 when reinvoking the shell, to work around problems with installers
10196 who put strange things like "cd" commands in their environments.
10198 2002-03-19 Akim Demaille <akim@epita.fr>
10200 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.

10205 * bin/autoscan.in (scan_file): Specify the location in `&used'
10209 2002-03-19 Akim Demaille <akim@epita.fr>
10211 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
10212 From Nishio Futoshi.
10214 2002-03-19 Akim Demaille <akim@epita.fr>
10216 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

10220 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
10221 (Limitations of Usual Tools): Add mkdir section.
10223 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
10224 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
10225 back on AS_DIRNAME to compute prefixes otherwise; this is
10226 roughly what mkinstalldirs does. That way, we need not have
10227 our own filename disassembler. The old disassembler did not
10228 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
10230 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
10231 Create at_test_all by a series of assignments,
10232 not by a single assignment of a long string. The latter causes ksh
10233 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
10234 presumably because of a buffer overrun.
10236 2002-03-14 Paul Eggert <eggert@twinsun.com>
10238 * lib/autotest/general.m4 (at_times_skip):
10239 Renamed from at_times. Now a boolean.
10240 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
10241 says 'times: not found'.
10243 2002-03-14 Akim Demaille <akim@epita.fr>
10245 * bin/autoreconf.in (&study_gettextize): New.
10246 (&autoreconf): Handle newest gettextize.

10270 2002-03-11 Andreas Schwab <schwab@suse.de>
10272 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
10273 does not do it if --with-lispdir is given.
10275 2002-03-08 Akim Demaille <akim@epita.fr>

10282 subdirectory should exist.
10284 2002-03-08 Akim Demaille <akim@epita.fr>
10286 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
10288 2002-03-08 Akim Demaille <akim@epita.fr>
10290 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
10291 aliases the actual variables, and modifications of the former
10294 2002-03-08 Akim Demaille <akim@epita.fr>
10296 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
10297 because of C-c: have m4 output in tmp files, then mv them.
10299 2002-03-08 Akim Demaille <akim@epita.fr>

10318 2002-03-04 Akim Demaille <akim@epita.fr>
10320 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
10321 * lib/autoconf/general.m4 (AC_INIT): More informative error
10322 message for LIBOBJ.
10324 2002-03-04 Akim Demaille <akim@epita.fr>
10326 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
10329 2002-03-04 Akim Demaille <akim@epita.fr>
10331 * doc/autoconf.texi (Transforming Names): Equality between target
10332 and host is irrelevant.
10333 (Specifying Names, Canonicalizing): Remove all references to the
10334 backward compatibility hooks. Rather, collect them all into...
10335 (Hosts and Cross-Compilation): this new section.
10336 * doc/install.texi (System Type): Ditto.
10337 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
10338 that `--host' implies cross-compilation.
10340 2002-03-04 Akim Demaille <akim@epita.fr>
10342 * doc/autoconf.texi (Evaluation Macros): New.
10343 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
10345 (_m4_foreach): Define the variant with immediate evaluation so
10346 that it contains exactly the items, not an expression which
10347 evaluation is the current item.
10348 (m4_re_string, m4_re_word): Don't over quote them.
10350 2002-03-04 Akim Demaille <akim@epita.fr>
10352 Instead of having stacking `shift's evaluated at the end, let
10353 `foreach' loops immediately evaluate them.
10355 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
10356 $*. This is the n-th time I change my mind, but hopefully this is
10359 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
10361 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
10362 it was only a hack for m4_text_wrap.
10363 (m4_car2): Remove, replaced by...
10365 (_m4_foreach): Adjust.
10366 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
10367 m4_bpatsubst for clarification.

10418 Fix Autoconf PR/207:
10419 AC_PREFIX_PROGRAM fails with dashed program names
10421 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
10422 variable when looking for the prefix program.

10458 2002-02-05 Akim Demaille <akim@epita.fr>
10460 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

10484 Also, pass `--reload-state=' on them, so...
10485 (handle_m4): don't.

10487 (M4sh): Rely on M4sugar.
10488 (Autotest, M4sh, M4sugar): Use frozen files.

10525 2002-01-28 Akim Demaille <akim@epita.fr>
10527 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
10528 AUTOTEST_PATH *after* it was set.
10529 Don't put `.' in the PATH: the user should be precise and `./' if
10530 needed. In addition, given that the test suite does some `cd', if
10531 `.' is in the path, the `tested programs' sections will report
10532 programs found in the test suite's directory, while during the
10533 tests (performed in their own directory), these programs are no
10534 longer visible. In other words, the results is confusing and

10574 2002-01-21 Akim Demaille <akim@epita.fr>
10576 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
10578 2002-01-21 Akim Demaille <akim@epita.fr>
10580 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
10581 message on invalid options.
10582 * bin/autom4te.in (parse_args): Don't use
10583 Autoconf::General::getopt with non valid options.

10601 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
10602 package.m4, since is really depends upon configure.ac, not
10604 * doc/autoconf.texi (testsuite Scripts): Adjust.
10605 * tests/Makefile.am (package.m4): New.
10606 EXTRA_DIST it since its a source.
10608 2002-01-06 Akim Demaille <akim@epita.fr>
10610 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
10611 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
10612 and PACKAGE_BUGREPORT from here...
10613 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
10615 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
10616 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
10617 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.

10636 2001-12-17 Jim Meyering <meyering@lucent.com>
10638 * doc/autoconf.texi (New Macros): Tweak wording.
10640 2001-12-14 Akim Demaille <akim@epita.fr>
10642 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
10643 trailing files, don't apply `-rf' to files which might not be
10644 created by configure (core, core.*, and *.core), but just `rm -f'.
10645 Suggested by Jonathan Kamens.
10647 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
10649 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
10651 2001-12-14 Akim Demaille <akim@epita.fr>
10653 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
10655 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
10657 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
10658 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
10659 abs_srcdir, top_srcpath to abs_top_srcdir.
10660 (_AC_OUTPUT_FILES): Adjust.
10661 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
10662 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
10663 * tests/wrappl.in, tests/wrapsh.in: Adjust.
10665 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
10667 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
10668 C/Fortran linking on HP/UX, by extracting the Fortran library
10669 search path from the LPATH line in the $F77 -v output.
10671 2001-12-12 Kevin Ryde <user42@zip.com.au>
10673 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
10674 forbidden file descriptors table.
10676 2001-11-26 Akim Demaille <akim@epita.fr>
10678 * bin/autoscan.in (%c_keywords): Build it at top level.
10679 Map to 1 in order to simplify its uses.
10681 2001-11-26 Akim Demaille <akim@epita.fr>
10683 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
10684 Remove $filepath, useless.
10685 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10686 variables, they are really part of the tokens.
10687 Split the input line on spaces and then look for tokens.
10688 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10689 because of `lex$U.$(OBJEXT)'.
10690 (&scan_files): Use "@list" instead of join.
10691 * doc/Makefile.am (CLEANFILES): Add *.fns.
10693 2001-11-26 Akim Demaille <akim@epita.fr>
10695 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
10696 Remove, replaced by...
10697 * tests/wrappl.in: Be common for all the Perl executables.
10698 In particular autoscan and autoheader want -I.
10699 * configure.ac: Adjust.
10700 * lib/autoscan/headers: errno.h is portable.
10702 2001-11-26 Akim Demaille <akim@epita.fr>
10704 * bin/autoscan.in (used): New.
10707 2001-11-26 Akim Demaille <akim@epita.fr>
10709 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
10711 (&scan_sh_file): Remove a duplicate pattern.
10712 (&check_configure_ac): Use long options.
10713 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
10715 2001-11-26 Akim Demaille <akim@epita.fr>
10717 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
10718 Before, having a line containing the opening of a multi line
10719 comment made the whole line be ignored.
10721 2001-11-26 Akim Demaille <akim@epita.fr>
10723 * doc/autoconf.texi (Using an Autotest Test Suite): New.
10724 (testsuite Scripts): Be one of its subsection.
10725 (Autotest Logs): New.
10727 2001-11-26 Akim Demaille <akim@epita.fr>
10729 Test groups are now run two directories deeper.
10731 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
10732 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
10734 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10735 top_srcdir, builddir and top_builddir.
10736 Use `at_*dir' relatively to the directory containing the
10737 suite, use `*dir' when relatively to the current group dir.
10739 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
10741 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
10742 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
10743 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
10746 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10748 * doc/autoconf.texi (Using System Type): Add an example of `case
10749 $host' usage so people quit using `case $target' everywhere.
10751 2001-11-22 Akim Demaille <akim@epita.fr>
10753 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10754 spotted by Jim Meyering.
10756 2001-11-16 Paul Eggert <eggert@twinsun.com>
10758 This patch implements a `long double' suggestion by Oliver Kiddle.
10760 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10761 static, to catch errors if the value isn't known at compile-time
10762 and the compiler supports dynamic arrays. Change its name from
10763 `_array_' to `test_array' to avoid potential name clashes.
10764 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10765 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10766 better than double. Catch a bug in GCC 2.95.2 x86.
10767 * doc/autoconf.texi (C Compiler): Document the above.
10770 2001-11-13 Akim Demaille <akim@epita.fr>
10772 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10774 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10776 2001-11-13 Akim Demaille <akim@epita.fr>
10778 * lib/autotest/general.m4 (AT_INIT): After having run the test
10779 group, go back to the initial directory, not to at_suite_dir.
10781 2001-11-13 Akim Demaille <akim@epita.fr>
10783 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10784 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10785 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10787 (AT_CHECK_CONFIGURE): Use absolute paths.
10788 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10789 The problem is still the old one: there is no means in M4 (that I
10790 know about) to create a defining macro, because there is no means
10791 to create `$1' etc., therefore, the defining macro ``swallows''
10792 all the arguments meant to the defined macro.
10794 2001-11-13 Akim Demaille <akim@epita.fr>
10796 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10797 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10799 * tests/aclocal.m4: Remove, as it is no longer used.
10801 2001-11-13 Akim Demaille <akim@epita.fr>
10803 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10804 variable names when referring to a single test group, or to
10805 `suite' when referring to the whole test suite.
10806 `at_last_test' is removed: m4 compute at_format itself.
10807 (at_stdout, at_stder1, at_stderr): New variables.
10808 (AT_CHECK): Use them.
10810 2001-11-13 Akim Demaille <akim@epita.fr>
10812 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10814 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10815 Do it as soon as a test fails, don't wait till the end of the test
10817 Don't remove $as_me.[0-9]*, since these files no longer exist.
10819 2001-11-13 Akim Demaille <akim@epita.fr>
10821 * tests/tools.at: Use absolute paths, since we are no longer run
10824 2001-11-13 Akim Demaille <akim@epita.fr>
10826 Now that tests are running in their own private dir, there is no
10827 need to list the files to remove at the end of tests groups.
10829 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10830 (AT_data_files, at_data_files): Remove.
10831 (AT_CLEANUP, AT_DATA): Simplify.
10833 Remove the group dir if !debug && !failed.
10834 * tests/atspecific.m4: Adjust.
10836 2001-11-13 Akim Demaille <akim@epita.fr>
10838 Start a new layout for Autotest: `testsuite' creates
10839 `testsuite.dir' in which the at-check-line etc. files are to be
10840 found, and `testsuite.dir/003' where the test group 3 is run.
10842 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10843 at_check_line_file, at_format, at_test_normalized, at_group_dir
10845 Create the directories.
10846 Use absolute paths for at- files.
10847 (AT_CHECK): Adjust.
10849 2001-11-11 Michael Matz <matz@kde.org>
10851 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10853 (m4_car): Properly quote arguments.
10855 2001-11-13 Akim Demaille <akim@epita.fr>
10857 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10858 with stricter rules on LIBOBJS.
10860 2001-11-12 Paul Eggert <eggert@twinsun.com>
10862 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10863 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10866 2001-11-12 Akim Demaille <akim@epita.fr>
10868 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10870 2001-11-12 Akim Demaille <akim@epita.fr>
10872 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
10873 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
10874 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10875 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10876 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10877 specify to what the macro should be defined (typically to 1).
10879 2001-11-12 Akim Demaille <akim@epita.fr>
10881 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10884 2001-11-12 Akim Demaille <akim@epita.fr>
10886 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10887 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10888 definition used by Automake where LEX is +/- "${missing} lex" and
10889 `missing' itself contains variables.
10891 2001-11-12 Akim Demaille <akim@epita.fr>
10893 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10894 Now that M4sh pushes BODY, the comments were output at the end of
10897 2001-11-08 Akim Demaille <akim@epita.fr>
10899 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10900 that we can trace macros from aclocal.m4.
10901 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10902 obsoleted, and redirect to the former anyway.
10903 Reported by Ralf Corsepius.
10905 2001-11-08 Akim Demaille <akim@epita.fr>
10907 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10908 processed only if present.
10909 * tests/torture.at (Configuring subdirectories): Use autoreconf
10910 instead of successive calls to autoconf.
10911 Add a nonexistent subdirectory to exercise the patch above.
10912 Reported by Ralf Corsepius.
10914 2001-11-08 Kevin Ryde <user42@zip.com.au>
10916 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10917 doesn't accept .S files.
10919 2001-11-07 Akim Demaille <akim@epita.fr>
10921 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
10922 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
10923 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10924 * bin/autom4te.in (warn_forbidden): New.
10925 (handle_output): Use it.
10926 Read m4_pattern_forbid with messages.
10928 2001-11-05 Akim Demaille <akim@epita.fr>
10930 * bin/autom4te.in (--normalize): Remove.
10931 * lib/autom4te.in: Adjust.
10933 2001-11-05 Akim Demaille <akim@epita.fr>
10935 * tests/Makefile.am (testsuite): Rename this target as...
10936 ($(TESTSUITE)): this.
10939 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10941 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10942 the --prefix option, also remove it's argument.
10944 2001-11-05 Akim Demaille <akim@epita.fr>
10946 * doc/autoconf.texi (testsuite Invocation): Update.
10947 (Writing testsuite.at): Update.
10949 2001-11-03 Akim Demaille <akim@epita.fr>
10951 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10953 2001-11-03 Akim Demaille <akim@epita.fr>
10955 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10956 (&file_name_is_absolute): New, wrappers around routines from
10958 Use and export them.
10959 (&find_configure_ac): Optionally take a directory where to look at.
10960 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10962 Default @ARGV to `.', not find_configure_ac.
10963 (&autoreconf): Argument is a directory.
10964 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10965 * doc/autoconf.texi (autoreconf Invocation): Update.
10967 2001-11-03 Akim Demaille <akim@epita.fr>
10969 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10970 (@export_forward_subs): New.
10971 Add basename, dirname, and fileparse.
10973 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10974 Don't look for aclocal flags if we already know aclocal is not
10976 Move aclocal.m4t only if it exists.
10977 Reported by Ezra Peisach.
10979 2001-11-03 Akim Demaille <akim@epita.fr>
10981 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10982 passed on command line, defaulting to ./configure.ac if present.
10983 (&maybe_autoreconf, File::Find): Remove, unused.
10984 (&autoreconf): If autoconf is not used, don't try to trace.
10986 2001-11-02 Akim Demaille <akim@epita.fr>
10988 * configure.ac: Bump to 2.52g.
10990 2001-11-02 Akim Demaille <akim@epita.fr>
10994 2001-11-02 Akim Demaille <akim@epita.fr>
10996 * config/config.guess, config/config.sub, doc/standards.texi:
10997 * config/lispdir.m4: Update from masters.
10998 * configure.ac: Bump to 2.52f.
11000 2001-11-02 Akim Demaille <akim@epita.fr>
11002 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
11003 Don't run aclocal when aclocal.m4 is not from aclocal.
11005 Don't run libtoolize and gettextize if --install is not given.
11007 2001-11-01 Paul Eggert <eggert@twinsun.com>
11009 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
11010 be invoked before _AS_LINENO_PREPARE.
11011 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
11012 than character ranges.
11014 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
11015 invoking AS_BASENAME. Set the locale variables to 'C' if
11016 possible, as POSIX requires this to get the traditional
11018 * doc/autoconf.texi (Special Shell Variables): Describe the above.
11020 2001-10-31 Paul Eggert <eggert@twinsun.com>
11022 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
11023 with {}, as that triggers a bug in Bash 2.05.
11025 (_AS_LINENO_PREPARE): Use Sed rather than
11026 Awk. Fix the sed prepass to work even if there are multiple
11027 instances of $LINENO on the same line. Do not substitute for
11028 other variables like $LINENOT. Do not check file dates; such a
11029 check is unreliable on sufficiently fast machines, and removing
11030 the check makes the code simpler and more reliable. Check for
11031 output and chmod failures.
11033 * doc/autoconf.texi (Special Shell Variables): Document
11036 2001-10-31 Akim Demaille <akim@epita.fr>
11038 * tests/Makefile.am (atconfig): Remove this target, Automake
11041 2001-10-31 Akim Demaille <akim@epita.fr>
11043 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
11044 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
11045 provided, while it is optional.
11046 * configure.ac: Adjust.
11048 2001-10-26 Paul Eggert <eggert@twinsun.com>
11050 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
11051 lib/Autom4te/Struct.pm:
11052 Require Perl 5.005_03 instead of just 5.005, as some tests fail
11055 * doc/autoconf.texi (Special Shell Variables): Document some
11056 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
11058 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
11059 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
11060 eval $LINENO is not portable in practice.
11062 2001-10-24 Akim Demaille <akim@epita.fr>
11064 * lib/Autom4te/General.pm (backname): New.

11079 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
11080 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since

11083 Assign to a char* var, to catch strerror_r that returns int*.
11085 * doc/autoconf.texi (Particular Functions):

11534 * tests/Makefile.am (package.m4): Remove.
11536 2001-09-22 Akim Demaille <akim@epita.fr>
11538 Rely on `$LINENO' when possible instead of `__oline__'.
11540 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
11541 `$LINENO' support replacement when not supported.
11542 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
11543 them explicitly to be sure they are not output before this section
11544 (via m4_require). Cosmetic only.

11546 * lib/autoconf/programs.m4: Replace all the occurrences of
11547 `__oline__' with `$LINENO'.

11557 2001-09-21 Akim Demaille <akim@epita.fr>
11559 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
11560 Suggested by Jim Meyering.
11562 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

11571 setting up ac_dir_suffix and ac_top_builddir.
11572 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.

11578 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
11579 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
11580 be used instead of ':'.
11581 * lib/autotest/general.m4: Replace occurrences of ':' in
11582 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
11584 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11586 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
11587 arguments. Fixed a typo.
11589 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11591 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
11592 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
11594 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11596 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

11603 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11605 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
11606 already have $file). Set output files to binary mode (helps avoid
11607 CR issues on DOSish systems).
11609 2001-09-19 Akim Demaille <akim@epita.fr>
11611 * lib/autotest/general.m4: Englishoes.
11612 From Tim Van Holder and Alexey Mahotkin.
11614 2001-09-18 Paul Eggert <eggert@twinsun.com>
11616 * doc/autoconf.texi (Common Shell Constructs): New node,
11617 documenting AS_DIRNAME.
11618 (Limitations of Usual Tools): Refer to it when discussing dirname.
11619 Also, update discussion of POSIX standard to reflect latest draft.
11621 * lib/autoconf/c.m4:
11622 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
11624 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11625 Do not pass a first argument with leading '-'
11626 to expr, by parenthesizing initial integers that might be negative.
11628 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
11629 now merely checks whether it is an error to pass an argument
11632 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
11633 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
11634 whether it is a (compile-time) error to pass an argument to
11635 getpgrp. This simpler test supports the revised documentation,
11636 and is all that AC_FUNC_GETPGRP's users really need.
11638 2001-09-18 Akim Demaille <akim@epita.fr>
11640 * doc/autoconf.texi (Limitations of Make) <$<>: New.

11648 2001-09-18 Paul Wagland <paul@wagland.net>
11650 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
11652 Add test for AS_BASENAME.
11653 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
11654 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11655 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11656 * tests/base.at: Fixed the expected responses. The old ones were
11658 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11659 the documentation claims it should (and how it behaved in 2.13).
11661 2001-09-18 Akim Demaille <akim@epita.fr>
11663 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
11664 the AC_CONFIG_COMMANDS invocation.
11665 This also solves the name clash problems.
11666 Don't set the package's ID.
11667 * lib/m4sugar/Makefile.am (version.m4): Revamp.
11668 No longer to be shipped.
11669 (version.in): Remove.
11670 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
11671 * lib/autoconf/status.m4: Adjust.
11672 Use `m4_PACKAGE_STRING'.
11673 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11674 the only optional argument is the name of the test suite.
11675 Expect `package.m4' to define the package signature.
11676 * lib/autom4te.in (Autotest): Add `package.m4?'.
11677 * tests/Makefile.am (package.m4): New.
11678 * tests/suite.at: ifnames is a victim.
11680 2001-09-18 Akim Demaille <akim@epita.fr>
11682 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
11683 AC_LIBSOURCE, AC_CONFIG_FILES.
11684 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
11685 program version string doesn't match the package's.
11686 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
11689 2001-09-17 Paul Eggert <eggert@twinsun.com>
11691 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11692 Allow expression to return any value that can fit into unsigned long
11693 (not int, as before). Check for output errors.
11695 2001-09-17 Bruno Haible <haible@ilog.fr>
11697 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11698 Always include <stdio.h> and <stdlib.h>. Evaluate
11699 the expression in an extra function before these includes. Call
11700 fprintf "%d" only after ensuring the argument is of type 'int'.
11701 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11703 2001-09-17 Paul Eggert <eggert@twinsun.com>
11705 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11706 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11707 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11708 when they don't exist.
11710 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11711 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11714 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11715 version with the version used by fileutils 4.1, except use
11716 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
11719 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
11721 2001-09-13 Akim Demaille <akim@epita.fr>

11761 * lib/autotest/general.m4 (AT_INIT): Create and remove
11762 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
11763 test suites can cohabit.
11765 2001-09-13 Akim Demaille <akim@epita.fr>
11767 * tests/mktests.sh: Don't output banners for empty test files.

11819 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

11822 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

11873 2001-09-05 Akim Demaille <akim@epita.fr>
11875 Be ready to handle filenames as stupid as `dnl.at', for if even
11876 the maintainer is dumb enough to do that...
11878 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11879 excellence in M4 quotation: consider `__file__' is active.
11881 And BTW, when invoking m4, pass the --include in the right order:
11884 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

11958 to m4sugar was lacking!
11960 2001-08-31 Akim Demaille <akim@epita.fr>
11962 * man/Makefile.am (.x.1): We really have to pass
11963 autom4te_perllibdir.
11965 2001-08-31 Akim Demaille <akim@epita.fr>
11967 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11968 debug scripts, in particular passing explicitly listed tests to

12017 Drop AC_MACRODIR dead for real.
12018 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
12019 `autoheader: `config.hin' is created'.
12020 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
12022 2001-08-31 Akim Demaille <akim@epita.fr>
12024 * bin/autoheader.in: Rewrite in Perl.

12029 * bin/autoconf.in (--include, -I): New option.
12030 Map --localdir, --autoconf-dir onto it.
12031 Forward autom4te's options instead of interpreting them.
12032 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
12033 There is no such envvar since the inception of autom4te.cfg.
12034 * bin/autom4te.in (&parse_args): Uniquify `@include'.
12035 * bin/autoupdate.in: Adjust, and perform more control.
12036 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
12037 * tests/autoconf: Dittowise.
12039 2001-08-31 Akim Demaille <akim@epita.fr>

12056 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

12058 * man/Makefile.am: Let help2man rely on PATH instead of trying to
12059 find the executables for it.

12061 * tests/atlocal.in: Remove all the obscure envvar manipulations.
12063 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
12064 indeed related to running the test suite, while passing
12065 --autoconf-dir and others is related to running non installed
12066 Autoconf executables. So don't do that, leave it to...

12068 * tests/autoscan: New.
12069 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

12086 Suggested by Paul Eggert.
12088 2001-08-29 Akim Demaille <akim@epita.fr>

12093 2001-08-29 Akim Demaille <akim@epita.fr>

12495 * doc/autoconf.texi: Work around Texinfo buglets.
12496 (Transformation Rules): One example is enough, users are expected

12555 autom4te.cache (it's a directory, not a file.
12556 * Makefile.am: Ditto (but maintainer-clean-local).
12558 2001-08-15 Akim Demaille <akim@epita.fr>
12560 * bin/autom4te.in (@m4_warning): New.
12561 (&handle_m4): Use it.
12562 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
12563 warnings are issued at each run.
12564 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
12565 is in the src tree.
12567 2001-08-15 Akim Demaille <akim@epita.fr>

12634 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
12635 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
12636 * doc/autoconf.texi (C Compiler Characteristics): Update

12642 magic values from an object file when cross-compiling.
12643 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12645 2001-08-10 Akim Demaille <akim@epita.fr>
12647 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12649 Suggested by Russ Allbery.
12651 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12653 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12654 current $prefix to the sub-configures.
12656 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12658 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12659 extension (needed on BeOS). Reported by Guido van Rossum.
12661 2001-08-09 Akim Demaille <akim@epita.fr>
12663 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12665 2001-08-07 Akim Demaille <akim@epita.fr>
12667 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12669 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12670 No need to remove the files before and after the each test, before
12671 each test and at the end of the suite is enough.
12672 Display only the children `times', not the shell's.
12673 If the test failed or was skipped, at-times is not available.
12675 2001-08-07 Akim Demaille <akim@epita.fr>
12677 Always produce testsuite.log, including when there are no
12678 failures. This helps getting information on skipped tests, and
12679 duration of the tests. Err, implement the latter btw.
12681 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12682 Dump information on the first run of each test.
12683 (AT_CLEANUP): Create `at-times' containing the duration of the
12686 2001-08-07 Akim Demaille <akim@epita.fr>
12688 The use of `dumpstat' revealed that `len' was used although it
12689 should not. m4_text_wrap was using it, but in the Autoconf world
12690 where it is legal. Hence (i) test M4sh in its own world, not
12691 Autoconf's, and (ii), ahem, fix the bug :)
12693 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12694 does not like `' instead of [].
12695 (AT_INIT): Forbid `^_?AT_'.
12696 And don't output such tokens.
12697 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12698 `script.as', and `autom4te.cache'.
12699 Remove `empty' and `macro' which are no longer used.
12700 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12701 * tests/m4sugar.at: Use it.
12702 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
12704 2001-08-07 Akim Demaille <akim@epita.fr>
12706 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
12708 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
12710 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
12712 2001-08-04 Akim Demaille <akim@epita.fr>
12714 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
12715 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
12717 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
12718 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
12719 (AC_F77_MAIN): Likewise.
12721 2001-08-04 Akim Demaille <akim@epita.fr>
12723 Don't rely on M4sugar outputting the patterns in files, since we
12724 might process the output _without_ running m4, hence without these
12727 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12728 * bin/autom4te.in (@Request::includes): Remove, unused.
12729 (@Request::source): Rename as...
12730 (@Request::input): this.
12731 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
12732 (&handle_output): Fetch the patterns from the traces.
12733 `$forbidden' and `$allowed' are constant: use m//o.
12734 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
12735 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
12737 2001-08-04 Akim Demaille <akim@epita.fr>
12739 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
12740 autoconf', i.e., in addition to caching traces, cache the output.
12742 * bin/autom4te.in (Request::cache): Rename as...
12743 (Request::id): this.
12744 ($cache, $icache, $tcache, $ocache): New.
12745 (&handle_m4): Save M4 output in the cache instead of $tmp.
12746 (&handle_output): Adjust.
12747 (&up_to_date_p): Check that the output cache is up to date too.
12748 (top level): Run `&handle_m4' iff force or the cache is invalid.
12749 Run `&handle_output' if the output cache is more recent.
12751 2001-08-04 Akim Demaille <akim@epita.fr>
12753 * bin/autom4te.in ($force): New.
12754 (&parse_args, &print_usage): -f, --force is a new option.
12755 (&handle_output): CPP directives might have spaces after `#'.
12756 (&parse_args): The first file only can be frozen.
12758 2001-08-04 Akim Demaille <akim@epita.fr>
12760 Don't let autom4te compute the `include' traces several times:
12761 first check that the trace cache file is up to date, and then
12762 compare its timestamp with that of the output.
12764 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
12765 the preamble. Don't require 5.005 as Autom4te::General does it,
12766 and better yet (use `use', not `require'!).
12767 * lib/Autom4te/Struct.pm: Rename the last occurrences of
12768 Class::Struct as Autom4te::Struct.
12769 * lib/Autom4te/General.pm (File::stat): Use it.
12770 (&mtime): New, export it.
12771 * bin/autom4te.in: Use it.
12772 Declare `$req' is invalid if it is outdated.
12773 Don't declare it valid before saving it if something went wrong.
12775 2001-08-04 Akim Demaille <akim@epita.fr>
12777 Autom4te shall not encode Autoconf data, and preselecting traces
12778 must be proposed to the users.
12780 * bin/autom4te.in (@required_trace): Remove.
12782 (&parse_args, &print_usage): -p, --preselect is a new option.
12783 (&up_to_date_p): Adjust.

12786 2001-08-04 Akim Demaille <akim@epita.fr>
12788 * tests/tools.at (autoconf --trace: user macros): Check traces on
12789 macros invoked without arguments, and macros invoked with multiple

12799 * bin/autoconf.in ($@): Work around the usual sh bug.
12802 2001-08-03 Akim Demaille <akim@epita.fr>
12804 Clean up the handling of the M4 builtins tracing exception.
12806 * bin/autom4te.in (Request::request): Don't complete M4 builtins

12809 (@m4_builtin): this.
12810 (%m4_builtin_alternate_name): New.
12811 (&parse_args): Complete the trace requests with alternate names.

12817 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
12818 m4_if, and m4_wrap.

12822 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
12823 (m4_divert_pop): Dump the whole diversion stack when a diversion
12825 * bin/autom4te.in (&handle_output): Remember of the first
12826 occurrence of a possibly undefined macro, not the last.
12827 Complain about the possibly undefined macros in the same order as
12828 the appear in the output.
12829 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
12830 * tests/tools.at (autoconf: forbidden tokens, basic)
12831 (autoconf: forbidden tokens, exceptions): No longer sort
12832 autoconf's stderr, as it is now deterministic.
12833 Check that `dnl' is caught.
12835 2001-08-01 Akim Demaille <akim@epita.fr>
12837 * configure.ac: Bump to 2.52c.

12854 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
12855 `END', as `Autom4te::General::END' will be triggered.
12856 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
12857 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
12858 system to run `mv', `rm', and `cmp'.
