504 * doc/autoconf.texi (Special Shell Variables): Warn about FPATH.
505 (Macro Names, Defining Directories): Don't mention PATH as a name
506 for a fully qualified file name, as this usage violates the GNU
507 coding standards and we shouldn't recommend it.
509 * lib/autotest/general.m4 (AT_INIT): Don't set PATH to the empty
510 string and then assume shell builtins like "test" will work.
512 2007-06-12 Noah Misch <noah@cs.caltech.edu>
514 * lib/autoconf/general.m4 (AC_SUBST): Raise a fatal error if VARIABLE is
515 not a valid shell variable name.
516 * tests/mktests.sh (ac_exclude_list): Add AC_ARG_VAR.

543 define HAVE_INT8_T, and likewise for similar macros.
544 Problem reported by Patrick Welche in

553 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp
554 choice, since that's what we do with --enable-largefile etc.
555 Redo indenting and assignments to simplify things a bit, and make
556 the parens work with Emacs.

640 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
642 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
644 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that

656 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
657 for a.* when searching for executables, as this prevents users

670 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
671 AC_CHECK_TYPE, AC_CHECK_TYPES.
672 * doc/autoconf.texi (Generic types): C types must be type-names
673 (the C terminology), not type-ids (the C++ term). C++ types
674 must not be anonymous.
675 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
676 for C++; this drops support for anonymous struct and union types,
677 which were problematic anyway.
678 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
679 for C++.
681 2007-04-12 Jim Meyering <jim@meyering.net>

693 * doc/autoconf.texi (Generic Types): Document the restrictions
694 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
695 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
696 with objects too. Document the restrictions on its use.
697 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
698 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
699 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
700 works but the latter doesn't, then it's a valid type.
701 This lets people use function types and so forth.
702 For C++ there doesn't seem to be a simple solution, so leave it alone.
703 (AC_CHECK_SIZEOF): Allow argument to be a variable.
704 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
705 AC_CHECK_TYPE; that wasn't documented or necessary.
707 2007-04-11 Stepan Kasal <kasal@ucw.cz>
709 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
710 when cross-compiling.

757 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
758 nonstandard grep R.E. escape sequences.
760 2007-03-17 Jim Meyering <jim@meyering.net>
762 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
763 (Limitations of Usual Tools): Also list \< and \>, and mention that
764 HP-UX's grep, like the one from Solaris, does not support that syntax.
766 2007-03-09 Stepan Kasal <kasal@ucw.cz>
768 * doc/autoconf.texi (Specifying Names): `--host' does not
769 change the build type.
771 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
773 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN

789 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
790 * doc/autoconf.texi (C Compiler): Document this. There is a new

875 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
876 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
877 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
878 substitution will still be done by the special code.

900 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
902 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
903 early on the reader side, drop stderr of the input to avoid
904 `broken pipe' error output; this may happen even with shell
905 builtin `echo' of some bash versions. Reports by Ian Macdonald
906 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
908 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

920 Fix some wording problems noted by Paolo Bonzini in:
921 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
922 * doc/autoconf.texi (Signed Overflow Examples): Give more
923 discussion about the allow_superuser_privileges example,
924 and change it a bit to make things clearer.
925 (Optimization and Wraparound): Clarify whether the compiler
926 will generate an infinite loop for the example derived from
927 Autoconf's mktime test.
928 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
929 Also, clarify unsigned multiplication overflow.
931 2007-01-04 Eric Blake <ebb9@byu.net>
933 * bin/Makefile.am (RELEASE_YEAR): New macro.
934 (edit): Use it to supply correct copyright year to scripts.

943 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
945 * doc/autoconf.texi (Integer Overflow): Revised based on today's
946 feedback. The most important changes document what happens when
947 you convert an out-of-range value to a signed integer type, and
948 say that (sum < a) != (b < 0) reliably detects overflow when sum =
949 a + b.
951 * doc/autoconf.texi (Integer Overflow): Greatly expand and
952 rewrite, taking notions from the recent discussion on the gcc and
953 autoconf mailing lists; please see
954 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
955 and follow the many links.
956 (Integer Overflow Basics, Signed Overflow Examples):
957 (Optimization and Wraparound, Signed Overflow Advice):
958 (Signed Integer Division): New sections.
960 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
962 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
963 preprocessor macro arguments in traced name.
964 * doc/autoconf.texi (Defining symbols): Document longstanding
965 support for AC_DEFINE-ing macros with arguments, and document
966 behavior when the same variable has multiple AC_DEFINEs.
967 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
968 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
969 macros directly, giving much shorter and simpler code.
971 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
973 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
974 space before "$ac_configure_args" to prevent a 'config.status
975 --recheck' failure if ac_configure_args doesn't contain a leading
976 space. This works around a problem with the XEmacs configure.ac,
977 which uses the (undocumented) ac_configure_args variable
978 inconsistently with Autoconf.
980 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
982 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
983 Include <limits.h>, and use its INT_MAX to rewrite the
984 j loop so that it does not overflow 'int'. Problem reported by
985 Ralf Wildenhues in
986 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
987 Play it safe by shifting left by 1 rather than multiplying by 2,
988 as GCC is less likely to optimize this away when the value
989 is signed (when it assumes overflow leads to undefined behavior).
990 Also, don't assume time_t uses two's complement.
992 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
994 * tests/torture.at (Substitute a 2000-byte string): Avoid using

996 dumps core on it. Report by Tim Rice.
998 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1000 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
1001 --disable-option-checking to --help output even when
1002 AC_PRESERVE_HELP_ORDER is not used.
1003 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
1004 --with argument, rather than argument with [-.] replaced by
1005 underscores.
1006 * NEWS: Fix typo in previous change; the news was in the
1007 wrong section.
1009 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
1011 * NEWS: Warnings are now generated by default for unknown
1012 --enable-* and --with-* options.
1013 * doc/autoconf.texi (Option Checking): Renamed from
1014 (Configure Option Checking). Tighten up the wording a bit.
1015 (External Software, Package Options): Cross-reference to Option
1016 Checking, and use this to shorten our section.
1017 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
1018 "$x" to test "x$foo" != x.
1019 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
1020 Don't warn if $enable_option_checking is "no".
1021 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
1022 ac_unrecognized_opts to the empty string.
1023 Don't echo the unrecognized opts, as this might mishandle
1024 backslashes or leading -.
1025 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
1026 usage next to the other --disable-FEATURE options in the
1027 help string.
1029 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1031 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
1032 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
1033 Print warning for unrecognized --with and --enable options
1034 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
1035 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
1036 Disable option checking when subdirs are configured.
1037 (AC_OUTPUT): If warnings are enabled, print warning about
1038 unrecognized --with and --enable options at the end of
1039 the configure output (as well as at the beginning).
1040 * doc/autoconf.texi (Option Checking): New node.
1041 Document new option warning functionality.
1043 2006-12-16 Eric Blake <ebb9@byu.net>
1045 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
1046 * NEWS: Start news for current version.
1048 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
1050 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1051 Define HAVE_GETMNTENT to 1, not to the empty string.
1052 Problem originally reported by Jochen Friedrich in
1053 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
1055 This change prompted by a problem report by Andrey Simonenko in
1056 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
1057 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
1058 object-like macros only, in the traditional portable character
1059 set.
1060 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
1061 Warn about attempts to define things that are not identifiers.
1062 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
1063 awful hack that AC_DEFINEd macro names containing parentheses.
1065 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
1067 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
1068 too drastic, even if Texinfo in theory requires it for info mode.
1070 (config.status Invocation): Renamed back from Recreating a
1071 Configuration).
1072 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
1073 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
1075 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1077 * NEWS: Version 2.61a.
1079 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1080 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1082 * NEWS: Document changes with echo and printf, and the lack
1083 of limits on the total size of multi-line values of substituted
1084 variables, and the AC_FUNC_FSEEKO fix.
1086 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
1088 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
1089 Writing configure.ac.
1090 (Autoconf Input Layout): Renamed from configure.ac Layout.
1091 (Recreating a Configuration): Renamed from config.status Invocation.
1092 (Obsolete Recreation): Renamed from Obsolete config.status Use.
1093 (acconfig Header): Renamed from acconfig.h.
1094 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
1095 (Writing Testsuites): Renamed from Writing testsuite.at.
1096 (Autom4te Cache): Renamed from autom4te.cache.
1098 * BUGS: Remove mention of VPATH problem, since it's now documented
1099 not to be a bug in the Autoconf build procedure itself, but rather
1100 a problem with the proprietary `make' programs.
1102 * doc/autoconf.texi (Build Directories): Add a cross reference
1103 to VPATH and Make.
1105 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
1106 * doc/standards.texi: Sync from gnulib.
1108 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
1109 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
1110 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
1111 generated automatically.
1113 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
1115 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
1116 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
1117 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
1119 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1121 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
1122 `CEOF$ac_eof' special marker, the awk script cannot contain a
1123 line matching `^CEOF', so this is not needed any more.
1124 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
1125 special marker in the test.
1127 2006-12-06 Stepan Kasal <kasal@ucw.cz>
1129 * tests/tools.at (autom4te preselections): Use `find -newer';
1130 remove one of the sleeps.
1132 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
1133 more readable, using ...
1134 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
1136 * doc/autoconf.texi (autoheader Invocation): Do not double-
1137 quote the parameter of `AH_BOTTOM' in the example.
1139 2006-12-05 Stepan Kasal <kasal@ucw.cz>
1141 * doc/autoconf.texi (Configuration Headers): Remove the
1142 example with multiple input files.
1143 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
1144 multiple input files.
1146 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1148 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
1149 creating the awk substitution script, handle one input line at a
1150 time, so that the maximum length of a substituted (multi-line)
1151 value is not limited by the size of the sed pattern space.
1152 The trade-off is a slightly repetitive sed script.
1153 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
1154 can only have up to 7 characters, due to Solaris 10 /bin/sed.
1155 * tests/torture.at (Substitute a 2000-byte string): Increase the
1156 test with several long lines, they should not be caught by sed
1157 limits any more.
1159 * tests/tools.at (autom4te preselections): New test, to flag
1160 entries missing from autom4te.cfg.
1161 Report by David Byron <dbyron@hheld.com>.
1163 * tests/torture.at (Substitute a 2000-byte string): Actually use
1164 AC_PROG_AWK, so the last change works as intended.
1165 (Substitute and define special characters): Likewise.
1166 (Substitute a newline): Likewise.
1168 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
1169 instead of `awk' consistently.
1170 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
1171 * tests/torture.at (Torturing config.status): Test both the
1172 result of AC_PROG_AWK and plain awk.
1173 (Substitute a 2000-byte string): Likewise.
1174 (Substitute and define special characters): Likewise.
1175 (Substitute a newline): Likewise.
1177 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
1179 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
1180 can be assigned to a function pointer. Problem reported by
1181 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
1182 part of a patch by Ralf Wildenhues in that same bug report.
1184 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
1186 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
1187 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
1189 2006-12-01 Eric Blake <ebb9@byu.net>
1191 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
1192 cross-compiling from cygwin to mingw.
1193 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
1194 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
1195 to lib/autoconf/c.m4.
1197 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1199 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
1200 string for more reliable failure. Wrap the entire test that
1201 causes the broken Solaris printf to dump core, in a subshell,
1202 so the segmentation fault message is reliably suppressed.
1203 Fix shell expansion errors by using /usr/ucb/echo always;
1204 avoid an error on systems without it by another subshell.
1205 Avoid m4 expansion of `$1'. Set the zeroth argument of the
1206 subshell-$as_echo to `as_echo', for better error message.
1208 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1210 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
1211 `BASH_SOURCE' contain a newline, set them to empty, as they may
1212 not be unset.
1214 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
1216 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
1217 years and is too hard to maintain now. The last straw was
1218 reported by Jerker Baeck in
1219 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
1220 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
1221 * doc/autoconf.texi (Particular Functions): Move
1222 AC_FUNC_SETVBUF_REVERSED from here...
1223 (Obsolete Macros): ... to here. Say that it does nothing now.
1224 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
1225 Turn into (almost) a no-op.
1227 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
1228 (AC_C_VOLATILE):
1229 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
1230 These macros are obsolescent and new applications shouldn't need them.
1231 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
1232 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
1233 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
1234 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
1235 (AC_FUNC_VPRINTF): Likewise.
1236 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
1237 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
1238 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
1240 * doc/autoconf.texi (Setting Output Variables): Mention that
1241 @VAR1@VAR2 has unspecified behavior. Problem reported by
1242 Ralf Wildenhues.
1243 * NEWS: Mention this.
1245 * Makefile.am: Put only a single '#' into the copyright notice,
1246 so that it's also present in the output file. Standardize wording
1247 in makefile copyright notices to match GNU coding standards.
1248 * bin/Makefile.am: Likewise.
1249 * doc/Makefile.am: Likewise.
1250 * lib/Makefile.am: Likewise.
1251 * lib/freeze.mk: Likewise.
1252 * lib/autoconf/Makefile.am: Likewise.
1253 * lib/autoscan/Makefile.am: Likewise.
1254 * lib/autotest/Makefile.am: Likewise.
1255 * lib/m4sugar/Makefile.am: Likewise.
1256 * man/Makefile.am: Likewise.
1257 * tests/Makefile.am: Likewise.
1258 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
1259 one-line file.
1261 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1263 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
1264 in the sed script that mangles the awk script: delete up to the
1265 first exclamation mark only.
1266 * tests/torture.at (Substitute and define special characters):
1267 Test '!' too.
1269 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1271 Rewrite config files generation: avoid quadratic growth in
1272 the number of substituted variables by using awk instead of sed
1273 for the bulk of the substitutions.
1274 * NEWS: Mention this.
1275 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
1276 forbidden in the output (and thus input) file.
1277 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
1278 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
1279 generate just one large awk script for substitutions,
1280 eliminating much of the earlier complexity, while adding some
1281 new complexity. Only expand the substitution templates at
1282 configure time, for smaller configure script size. If
1283 _AC_SUBST_FILES are used, test 'awk' for working getline support
1284 at config.status time. If absent, interpolate through the
1285 shell. The awk script was written with much help
1286 from Paolo Bonzini and Paul Eggert.
1287 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
1288 (_AC_SED_FRAG_NUM): Likewise.
1289 (_AC_SUBST_CMDS): Renamed from...
1290 (_AC_SED_CMDS): ...this.
1291 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
1292 * tests/torture.at (Substitute a 2000-byte string): Also
1293 substitute a line with 1000 words, and a variable with several
1294 long lines.
1295 (Substitute and define special characters): Test awk special
1296 characters, and put substitution input strings `@foo@' in the
1297 output, to test that no recursion happens; test several other
1298 combinations from Paolo Bonzini.
1300 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
1302 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
1303 that replaced echo with AS_ECHO where this wasn't necessary.
1304 Problem reportd by Ralf Wildenhues.
1305 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
1306 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
1307 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
1309 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1311 * lib/freeze.mk (GREP): Removed, no need to initialize this.
1313 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
1315 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
1316 that traditional Awk lacks 3-arg "split". It has it.
1317 Mention that FS must be a single character, and a few other
1318 99-byte limits of traditional Awk.
1319 Mention that if (i in a) doesn't work with traditional Awk.
1321 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
1323 * tests/autotest.at (BSx641-newline in command):
1324 (BS-BS-newline in command, BSx640-newline in command):
1325 (Newline-CODE-BS-newline in command):
1326 (Single-quote-BS-newline in command):
1327 (Single-quote-newline-BS-newline in command):
1328 Use printf '%s\n' instead of echo, for portability to hosts
1329 where echo interprets backslashes. This will break on hosts
1330 that lack printf, but for now let's assume all such hosts
1331 are dead (if not, we should get reports of test failures).
1333 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
1335 'echo' has some portability problems, when given a first argument
1336 with a leading '-', or when given any argument containing '\'.
1337 Avoid using 'echo' in these cases.
1338 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
1339 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
1340 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1341 * lib/autotest/general.m4 (AT_INIT): Likewise.
1342 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
1343 argument might be unportable.
1344 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
1345 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.

1347 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
1348 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
1349 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
1350 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):

1361 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
1362 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
1363 * bin/autoconf.as: Redo verbose flag implementation, as the old
1364 scheme wouldn't work with AS_ECHO.
1365 * lib/autotest/general.m4 (AT_INIT): Likewise.
1366 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
1367 Don't use ECHO_T, since ECHO_N is now reliable.
1368 * lib/autotest/general.m4 (AT_INIT): Likewise.
1369 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
1370 rather than using a here-document to put the script into a file.
1371 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
1372 use AS_ECHO.
1373 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
1374 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
1375 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
1376 bug, but we might as well stop using ECHO_N and ECHO_C internally.
1377 * lib/autotest/general.m4 (AT_SETUP): Likewise.
1378 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
1379 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1380 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
1381 operand, as AS_ECHO requires. Avoid double file name expansion.
1382 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
1383 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
1384 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
1385 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
1386 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
1387 Double-quote strings that would otherwise contain M4 comments.
1388 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
1390 * configure.ac (AC_INIT): Bump to 2.61a.
1391 * NEWS: Likewise.
1393 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
1395 Version 2.61.
1397 * configure.ac (AC_INIT): Bump to 2.61.
1398 * NEWS: Likewise.
1400 * tests/autotest.at (Macro with backslash in a test title):
1401 Comment out for now, as this tests neither fails nor passes
1402 reliably. Problem reported by Ralf Wildenhues.
1404 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
1406 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
1407 in previous change, which caused test failures.
1409 2006-11-16 Stepan Kasal <kasal@ucw.cz>
1411 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
1412 code for --enable, --disable, --with, and --without to...
1413 (_AC_INIT_PARSE_ENABLE): ... a new macro.
1414 * doc/autoconf.texi (Package Options):
1415 * NEWS: Document that AC_ARG_ENABLE allows dots, too.

1451 Both of these suggestions from Eugene Y. Vasserman.
1454 Import these changes from texinfo via gnulib:
1456 2006-11-08 Karl Berry <karl@gnu.org>
1458 * build-aux/texinfo.tex (\dopdfimage): look for png, jpg/jpeg/JPG, and

1482 non-working g++ installation.
1484 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1485 and Joel E. Denny <jdenny@ces.clemson.edu>

1494 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set

1496 Imported from a similar patch to gnulib by Bruno Haible.
1498 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
1500 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
1501 * doc/autoconf.texi (C Compiler): Document them.
1502 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
1503 New macros, taken from gnulib.
1505 2006-11-07 Paul Eggert <eggert@cs.ucla.edu>

1516 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
1517 and Stepan Kasal <kasal@ucw.cz>

1524 argument. Extend to check titles printed by ./micro-suite and
1525 ./micro-suite -l and the title in micro-suite.log.
1526 (Backquote in a test title,
1527 Single-quote in a test title,
1528 Double-quote in a test title): Don't expect failure anymore.
1529 (Backslash in a test title): Put a non-whitespace character after the
1530 backslash so that Bourne shells might actually see it as an escape
1531 sequence.
1532 (Brackets in a test title,
1533 Pound in a test title,
1534 Comma in a test title,
1535 Quoted Macro in a test title,
1536 Macro in a test title,

1539 Macro with double-quote in a test title,
1540 Macro with backslash in a test title): New tests expected to fail.
1541 * tests/torture.at (#define header templates): M4-quote this title in
1542 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
1543 The visible effect was a stray [] in the testsuite output.
1545 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1547 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
1548 `trap ... 0' inside a function, for AIX sh.
1550 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
1552 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
1553 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
1554 5363) simply issues a warning when dividing by zero at compile
1555 time. Problem reported by Elias Pipping.
1557 2006-10-26 Eric Blake <ebb9@byu.net>
1559 * THANKS: Update.
1560 * doc/autoconf.texi (Evaluation Macros): Improve the example to
1561 show effect on macros that expand with commas.
1562 Reported by Joel E. Denny.
1564 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
1565 Also work with M4 1.4.8.

1577 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
1579 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm

1586 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
1588 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1589 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
1590 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
1591 reported by Nelson H. F. Beebe for Coreutils 6.4.
1593 * tests/tools.at (autoconf --trace: user macros): Remove test
1594 for tracing multiline macros, since m4 1.4.7a uses a different
1595 way to number lines. Problem reported by Ralf Wildenhues.
1597 2006-10-24 Stepan Kasal <kasal@ucw.cz>
1599 * bin/autom4te.in (handle_m4): Do not redirect stdin to
1600 /dev/null since the heuristics for interactive behaviour was
1601 fixed in CVS m4.
1603 * bin/autom4te.in: With --force, always refresh the output
1604 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
1606 * bin/autoconf.as: Fix the verbose message at the end.
1608 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

1624 AC_CACHE_CHECK_INT, since it's no longer public.
1625 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
1626 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
1628 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1630 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
1632 2006-10-19 Eric Blake <ebb9@byu.net>
1634 * lib/m4sugar/m4sugar.m4 (m4_mkstemp): New macro.

1636 * lib/emacs/autoconf-mode.el (autoconf-font-lock-keywords): Color
1637 m4_mkstemp.
1638 * doc/autoconf.texi (Redefined M4 Macros): Document m4_mkstemp.

1654 2006-10-14 Stepan Kasal <kasal@ucw.cz>
1656 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
1657 looking for special shell characters.
1658 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
1659 macro defined by AS_VAR_PUSHDEF before passing it as a
1660 parameter.
1661 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
1662 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

1671 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1673 (Imported from Automake.)
1674 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
1675 which incorrectly sets the mode of an existing destination
1676 directory. In some cases the unpatched install-sh could do the
1677 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
1678 system. We hope this is rare in practice, but it's clearly worth
1679 fixing. Problem reported by Alex Unleashed in
1680 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
1681 Also, don't bother to check for -m bugs unless we're using -m;
1682 suggested by Stepan Kasal.
1684 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1686 Import this change from Automake:
1688 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
1689 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
1690 is enabled by default with gnu and gnits strictness.
1691 Report from Bruno Haible.
1693 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
1694 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
1695 gnu and gnits modes.
1697 Import this change from Config:
1699 2006-09-20 Ben Elliston <bje@gnu.org>
1700 * build-aux/config.sub (score, score-*): New.
1702 Import this change from Gnulib:
1704 2006-09-16 Karl Berry <karl@gnu.org>
1705 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
1706 to avoid sectioning errors.
1708 Import these changes from Texinfo:
1710 2006-10-04 Karl Berry <karl@gnu.org>
1711 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
1712 (\quoteexpand): rename to \rquoteexpand.
1713 (\codequoteleft): new def, to look for @set codequotebacktick.
1714 (\lquoteexpand, \quoteexpand): new defs.
1715 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
1716 (\code): must use new \...Char values, since now ` is active.
1718 2006-08-26 Karl Berry <karl@gnu.org>
1719 * build-aux/texinfo.tex (\textdegree): New command.
1721 2006-08-12 Karl Berry <karl@gnu.org>
1722 * build-aux/texinfo.tex (error \box0): smaller font.
1724 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1726 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
1728 2006-10-13 Stepan Kasal <kasal@ucw.cz>
1730 * doc/autoconf.texi (Autoheader Macros): Warn that the text
1731 added to the template can get mangled.
1733 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1735 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
1736 include the default headers, and redefine obstack_chunk_alloc
1737 and obstack_chunk_free. Fixes false failure with glibc.
1739 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
1741 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
1742 for backward compatibility with Libtool 1.5.22. Problem reported
1743 by Ralf Wildenhues.
1745 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1747 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
1748 AC_PROG_CC.
1749 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
1751 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
1753 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
1754 the NonStop platform.
1755 * doc/autoconf.texi (Posix Variants): Likewise.
1756 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
1758 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
1759 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
1760 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
1761 Use a better substitute, by inspecting the output of "ls"
1762 rather than just using ":".
1763 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
1764 rather than AS_EXECUTABLE_P, since we needn't worry about
1765 non-regular files here.
1767 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
1768 due to configuration hassles with this. See Tonya Underwood's report
1769 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
1770 * doc/autoconf.texi (Special Shell Variables): Likewise.
1772 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
1773 Stepan Kasal <kasal@ucw.cz>

1778 2006-10-11 Stepan Kasal <kasal@ucw.cz>
1780 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
1781 initialization which is not inherited through the environment
1782 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
1783 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
1785 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
1787 * doc/autoconf.texi (Limitations of Usual Tools): Describe
1788 problems with mkdir -p -m.
1790 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
1792 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
1793 comment about ac_cpp_err; it was incorrect, and anyway
1794 ac_cpp_err is being removed below.
1795 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
1796 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
1797 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
1798 nobody uses it.
1799 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
1800 with werror_flag and conftest.err and so forth. This is more
1801 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
1802 and anyway the user shouldn't normally want to see this gorp logged.
1803 Problem reported by Ralf Wildenhues.
1804 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
1805 empty, not 'no', since the rest of the code uses 'test -z'.
1807 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
1809 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1810 Use a single call to AC_DO_TOKENS rather than multiple, for
1811 efficiency.
1812 (_AC_LINK_IFELSE): Test that resulting file is executable.
1813 Problem reported by mwoehlke in
1814 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
1816 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
1817 than creating a file to use with test -x; this is much faster.
1819 2006-10-02 Bruno Haible <bruno@clisp.org>
1821 * lib/autom4te.in (Automake-preselections): Add
1822 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
1824 2006-09-27 Stepan Kasal <kasal@ucw.cz>
1826 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
1827 standard error, `experr' should be used, not `expout'.
1829 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1831 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
1832 fseeko testing program twice; just use the earlier result.
1833 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1834 Set cache var to 'unknown' (not 'no') if leaving the macro unset
1835 still doesn't let the program compile.
1836 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
1837 failed.
1839 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
1840 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
1841 include it, without including anything else.
1842 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
1843 expressions.
1844 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
1846 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1848 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
1849 `error.h', and include it, for a `error_at_line' prototype.
1850 Use a nonempty format string in the link test.
1851 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
1852 for a declaration of wait3.
1854 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1856 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
1857 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
1858 can apply to constants too, and that it checks for macro defns.
1859 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
1860 and simply cast the identifier to void. This handles structure
1861 values. Problem reported by Ralf Wildenhues.
1862 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
1864 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1883 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): Avoid `gcc -Wall'
1884 warnings (uninitialized value).
1885 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
1886 present.
1887 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add
1888 parentheses.

1973 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
1974 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now

1997 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
1998 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
1999 accept files with extension `.f'. For consistency, also prefer

2076 broken lex libraries like native ia64-hp-hpux11.22; see
2077 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
2078 work around the problem by preferring an empty LEXLIB to -lfl or
2079 -ll. Let the user set LEXLIB='' to indicate no library needed.
2081 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
2082 * README: Likewise.

2329 * doc/autoconf.texi (Volatile Objects): New section.
2331 * NEWS: Document previous change.
2333 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
2335 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
2336 Require that long long int be at least 64 bits wide. C99 requires
2337 this and enough programs depend on it so we should check for it.
2338 Bruno Haible reports in
2339 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
2340 that long long int is 32 bits wide with some nonstandard compilers.
2341 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
2343 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
2345 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2346 to a nonexistent file, so that we don't have to worry about
2347 a local site configuration that doesn't use /usr/local.
2348 Problem reported by Keith Marshall in
2349 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
2351 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
2353 * doc/autoconf.texi: Be more consistent about using @acronym with
2354 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
2355 quite right (it talked about "OSF/Tru64", even though the
2356 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
2357 and it even mentioned "OSF 4"!) and at this point there's little
2358 reason to talk about OSF any more, since it died in 1994.
2359 (Specific Compiler Characteristics): Simplify example of
2360 negative-size array.
2361 (File Descriptors): Reorder to make the text flow better.
2362 Remove joke about "appreciate the various levels"; I didn't get it.
2363 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
2364 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
2365 (File Descriptors, Limitations of Usual Tools):
2366 Tone down the advice against renaming or removing open files.
2367 (Limitations of Usual Tools): Add a new section, on 'rm'.
2369 2006-06-26 Stepan Kasal <kasal@ucw.cz>
2371 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
2372 -lXt in LIBS, idea from Karsten Hopp; this was due since
2373 this change:
2375 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2376 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2377 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2378 (which belong to Xt, not X itself). See Debian bug 327655.
2380 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2382 * configure.ac (AC_INIT): Bump to 2.60a.
2383 * NEWS: Update.
2385 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2387 Version 2.60.
2389 * configure.ac, NEWS: Update.
2391 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2393 * config/texinfo.tex: Sync from upstream.
2395 * bin/autom4te.in (handle_traces): Transform the `@S|@'
2396 quadrigraph correctly in traces.
2398 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
2399 Fix typos.
2401 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
2402 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
2403 not defined.
2404 * doc/autoconf.texi (Changed Directory Variables): New node,
2405 to document the whole `datarootdir' business a bit better.
2406 * NEWS: Update.
2407 * tests/torture.at (datarootdir workaround): Extend test.
2408 Prompted by report by Alexandre Julliard.
2410 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
2412 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
2413 when using default mode of IBM C 6 for AIX. Problem and two-line
2414 fix reported by Larry Jones.
2416 2006-06-22 Alexandre Julliard <julliard@winehq.org>
2418 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
2419 about literal '${datarootdir}' if a definition is found in the
2420 output file.
2422 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
2424 * NEWS: Use "M4" rather than "m4" when appropriate.
2425 Problem reported by Eric Blake.
2426 * doc/autoconf.texi: Likewise.
2427 Use @acronym around BSD, GCC, and GNU when appropriate.
2428 (Why GNU M4): Renamed from "Why GNU m4".
2429 (Redefined M4 Macros): Mention that Posix
2430 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
2431 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
2432 to int.
2434 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2436 * bin/autom4te.in (handle_output): Do not forbid the empty
2437 pattern.
2438 * tests/tools.at (autoconf: the empty token): New test.
2440 2006-06-20 Stepan Kasal <kasal@ucw.cz>
2442 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
2443 calls, so that we do not care whether they are LIFO or FIFO;
2444 in the m4_wrap, do not check which diversion is the topmost
2445 one, just check that the stack is balanced at the end.
2446 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
2447 base diversion forever--pop the previous diversion before
2448 opening the new one; consequently, remove the m4_wrap call.
2449 * lib/autotest/general.m4 (AT_INIT): Likewise.
2450 * tests/m4sugar.at: Do not use
2451 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
2453 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
2454 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2456 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
2457 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
2458 Rework example of m4wrap token-pasting trouble so that it doesn't
2459 care whether it's LIFO or FIFO.
2460 Fix some "contrary to"s that are awkward in English.
2462 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2464 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
2465 to `yes' instead of `int$1_t' if the type is found, for more
2466 consistent configure output (where $1 is the number of bits).
2467 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
2468 Suggested by Bruno Haible.
2470 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
2471 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
2472 with system headers. Report by Bruno Haible.
2474 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2476 * config/config.guess, config/config.sub: Sync from upstream.
2478 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
2479 in order to avoid picking up an older installed frozen m4sh.m4f.
2480 Besides an outdated shell startup, this could have been created
2481 by an earlier M4 version with incompatible frozen file format.
2483 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
2485 * README: Recommend m4 1.4.4 instead of 1.4.3..
2486 * doc/autoconf.texi: Likewise.
2487 (Special Chars in Names): Say that $(.FOO) is portable, as
2488 suggested by Stepan Kasal.
2489 (Installation Directory Variables, Build Directories):
2490 (Automatic Remaking, Subdirectories, Fortran Compiler):
2491 (Making testsuite Scripts, Defining Directories):
2492 Quote variable usages better.
2493 (Making testsuite Scripts): Add clean-local rule to makefile
2494 snippet, by Eric Blake.
2495 (Installation Directory Variables): Fix table item font.
2496 Reword slightly to clarify. Generalize advice about
2497 not using special characters to include all file-related
2498 vars, not just VPATH.
2499 (Special Chars in Variables): Warn about special characters in
2500 $(srcdir) too.
2501 (Assignments): Clarify default-value example as suggested by
2502 Ralf Wildenhues in
2503 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
2504 (Special Shell Variables): Note leading ./ or ../, as suggested
2505 by Eric Blake.
2506 (Limitations of Builtins): Under cd, warn about CDPATH.
2507 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
2508 Ralf Wildenhues.
2510 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2512 * doc/autoconf.texi (Configuration Actions): Remove duplicate
2513 `@var', for texi2html.
2514 (Systemology): Some more word wrapping, for DVI output.
2515 (autom4te Invocation): The short option for `--melt' is `-M',
2516 not `-m'.
2518 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
2520 * doc/autoconf.texi: More formatting and English tweaks,
2521 many suggested by Ralf Wildenhues.
2522 Reword to avoid "@code{...}'s" and the like, since it's ugly
2523 with Emacs info mode. discontents -> woes.
2524 Put a few "will"s back. time stamp -> timestamp.
2525 side-effect -> side effect.
2527 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
2529 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
2530 Warn about $@ not persisting. Problem reported by Julien Danjou in
2531 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
2532 (Special Chars in Names): Renamed from Leading _ in Macro Names.
2533 Mention other special chars, too.
2535 2006-06-14 Eric Blake <ebb9@byu.net>
2537 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
2539 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
2541 * doc/autoconf.texi: Some systematic minor improvements, as
2542 follows. Use "makefile" when talking about makefiles
2543 generally (which might be named "makefile" or "Makefile" or even
2544 "foo.mk"), "Makefile" when talking about a specific makefile
2545 called "Makefile". This unclutters the text from weird quotes
2546 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
2547 values" rather than "@var{foo}s" and similar constructs containing
2548 "}s". Use "Make rules" rather than "Makefile rules". Minor
2549 English-language improvements. Change the prefix "sub-" to "sub"
2550 and "re-" to "re".
2551 Put blank lines around examples more consistently.
2552 Avoid "rather" and "very" as intensifiers.
2553 Avoid "will" as an auxiliary.
2554 (Limitations of Make): Split this node into....
2555 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
2556 (Leading _ in Macro Names, Backslash-Newline-Newline):
2557 (Backslash-Newline Comments, Long Lines in Makefiles):
2558 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
2559 (obj/ and Make, make -k Status, VPATH and Make):
2560 (VPATH and Double-colon, $< in Explicit Rules):
2561 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
2562 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
2563 New nodes, resulting from splitup of Limitations of Make.
2564 All cross-references changed. Raise the top node from
2565 a section to a chapter, and all subnodes accordingly.
2566 Redo the introductory wording to match the new organization.
2567 (Installation Directory Variables): Use an example that is
2568 closer to what Autoconf actually does. Mention that VPATH's
2569 value should not contain metacharacters or white space.
2570 (Fortran Compiler): Fix a VPATH bug in an example.
2571 (Leading _ in Macro Names): Mention that this problem is no longer
2572 of practical concern.
2573 (VPATH and Make): Reword the advice to make it clearer
2574 that Autoconf and Automake support VPATH in non-GNU make, but
2575 many packages have bugs in this area.
2576 ($< in Explicit Rules): Refer to Build Directories rather
2577 than using a (non-VPATH-safe) example.
2578 (Automatic Rule Rewriting): Mention the sort of disaster that
2579 can ensue with Solaris-style rule rewriting with VPATH.
2581 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2583 * doc/install.texi (Compilers and Options): Weaken the
2584 suggestion to use GNU make for VPATH builds.
2586 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
2587 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
2589 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
2590 in regular expression.
2592 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2594 * doc/autoconf.texi (Installation Directory Variables):
2595 Drop extra @samp from `@table @samp' item.
2596 (Limitations of Usual Tools): Comment fix.
2597 Do not nest @samp just to point to other table items.
2598 (Writing testsuite.at) <AT_CHECK>: The second argument to
2599 `@dvar' is already @samp'ed.
2600 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
2601 do not use @var in the second argument.
2603 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
2605 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
2606 $as_shell.exe too. Problem reported by Andreas Buening in
2607 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
2609 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2611 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
2612 `unused variable' compiler warning, for `-Wall -Werror'.
2613 Reported by Jaap Haitsma in
2614 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
2616 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
2618 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
2619 case the compiler dumps core. Problem reported for
2620 OpenServer 5.0.7 by Tim Rice in
2621 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
2622 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2623 Likewise.
2625 2006-06-06 Tim Rice <tim@multitalents.net>.
2627 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
2628 "ERROR" only shows up in "make check" output if there is an
2629 error.
2631 2006-06-06 Eric Blake <ebb9@byu.net>
2633 * tests/tools.at (automatically allowed tokens): Fix typo.
2635 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2637 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
2639 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
2640 typically overflows on x86 CPUs, even though the C standard
2641 requires otherwise.
2643 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2645 * configure.ac (AC_INIT): Bump to 2.59e.
2646 * NEWS: Update.
2648 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2650 Version 2.59d.
2652 * config/texinfo.tex: Sync from upstream.
2654 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
2655 seen, invoke libtoolize with `--ltdl' argument.
2656 * lib/autom4te.in (Autoreconf-preselections): Adjust.
2657 * NEWS: Update.
2658 Suggested by Eric Blake.
2660 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2662 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
2663 reported by Ralf Wildenhues.
2664 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
2666 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2670 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2672 * doc/autoconf.texi: Modernize some of the references to Solaris.
2674 2006-06-05 Stepan Kasal <kasal@ucw.cz>
2676 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
2677 message issued by AC_REQUIRE.
2678 * tests/m4sugar.at: Check m4_require's error message.
2679 * tests/base.at: Check AC_REQUIRE's error message.
2680 * tests/local.at (AT_CHECK_M4): New macro, almost identical
2681 to...
2682 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
2683 AT_CHECK_M4.
2684 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
2685 `expout' as the last parameter.
2686 * tests/tools.at: Adapt to the above change.
2688 2006-06-04 Stepan Kasal <kasal@ucw.cz>
2690 * doc/autoconf.texi (Limitations of Usual Tools): Correct
2691 information about race-free implementations of mkdir.
2693 2006-06-04 Eric Blake <ebb9@byu.net>
2695 * bin/autoreconf.in (help): Document M4 environment variable.
2696 * bin/autoconf.as (Usage): Likewise.
2697 * bin/autom4te.in (help): Likewise.
2698 * doc/autoconf.texi (autom4te Invocation): Likewise.
2700 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
2702 * NEWS: GNU make now recommended for VPATH builds.
2703 Mention that some macros are now documented to be obsolescent.
2704 * doc/autoconf.texi:
2705 Prefer "current" to "modern" to describe
2706 currently-used (albeit perhaps old-fashioned) hosts.
2707 Mention which ancient features no longer need to be worried about.
2708 setgid -> set-group-ID
2709 setuid -> set-user-ID (these are the Posix terms)
2710 Fix some misuses of "only".
2711 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
2712 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
2713 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
2714 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
2715 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
2716 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
2717 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
2718 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
2719 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
2720 Mention that these macros are obsolescent.
2721 (Installation Directory Variables): shall -> should
2722 (File Descriptors): Mention that 0, 1, 2 might get reopened.
2723 Mention that it's now safe to use 3 and 4.
2724 (Limitations of Usual Tools): cp -r is now specified by Posix.
2725 Omit longwinded and obsolescent discussion of cp -f.
2726 Modernize discussion of expr, ls.
2727 (Limitations of Make): Modernize discussion of VPATH builds.
2728 Mention $? as a workaround in some cases.
2729 * doc/install.texi (Basic Installation):
2730 Mention "./configure; make; make install" first. Be more
2731 specific about why this file is generic. Remove unnecessary
2732 parens. Remove misleading "only". Remove obsolete advice
2733 about csh. Don't say "configure" takes awhile; say it
2734 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
2735 and CC=c99 rather than CC=c89, as these are blessed by current
2736 Posix. Recommend GNU make if doing a VPATH build.
2738 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
2740 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
2741 examples involving shell prompts.
2743 2006-06-02 Stepan Kasal <kasal@ucw.cz>
2744 and Paul Eggert <eggert@cs.ucla.edu>
2746 * doc/autoconf.texi (Here-Documents): Add details about the
2747 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
2748 use "here-documents" instead of "here documents".
2750 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2752 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
2754 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
2756 * doc/autoconf.texi (File System Conventions): Warn about ":"
2757 anywhere in directory names.
2759 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
2761 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
2762 about quoting the case statement, just in case.
2763 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
2764 was fixed in ksh93g; reported by Ralf Wildenhues.
2766 2006-05-31 Stepan Kasal <kasal@ucw.cz>
2768 * doc/autoconf.texi (System Services): Do not document
2769 overriding EXEEXT via ac_cv_exeext=ext.
2770 (Particular Programs) <AC_PROG_MKDIR_P>:
2771 Document that ${MKDIR_P} understands --.
2772 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
2773 comment.
2775 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2777 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
2778 argument with leading hyphen. Problem reported by Paul Eggert.
2780 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2782 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
2783 about quoting ac_try: quote all of it, if any of it seems suspicious.
2784 This means we don't have to worry about ${ or sed any more.
2785 Also, double-quote the case statement, to work around misuses via
2786 underquoting as reported by Ralf Wildenhues in
2787 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
2788 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
2789 undocumented and dangerous macro.
2790 Problem reported by Ralf Wildenhues in
2791 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
2793 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2795 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
2796 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
2797 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
2799 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2801 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
2802 since evidently some packages rely on the old, broken behavior.
2803 Problem reported by Ralf Wildenhues in
2804 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
2805 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
2806 pre-2006-05-26 definitions, but leave in the comments that
2807 these macros are dangerous and should not be used.
2808 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
2809 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
2810 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
2811 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
2812 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
2814 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2816 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
2817 the use of 'tr', since this is our only use of 'tr'.
2819 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2820 and Paul Eggert <eggert@cs.ucla.edu>
2822 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2823 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2825 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2827 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2828 the output file in the `${datarootdir}' test.
2830 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2831 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2833 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2834 mention of `datarootdir' in the input file(s), but literal
2835 `${datarootdir}' in the output file, and we haven't warned yet,
2836 then warn as well: the user may have (erroneously) used
2837 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2838 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2839 * tests/torture.at (datarootdir workaround): Extend this test.
2840 * NEWS: Update.
2842 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2843 and Paul Eggert <eggert@cs.ucla.edu>
2845 * doc/autoconf.texi (autoheader Invocation): The first argument to
2846 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2847 alternatives and clear up the language a bit.
2849 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2851 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2852 ac_config_guess, ac_config_sub, ac_configure.
2853 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2854 Fix typo that prevented an unnecessary space from being removed.
2855 Problems reported by Ralf Wildenhues in:
2856 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2858 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2860 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2861 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2862 Don't use the term "thread-safe" to talk about mkdir race
2863 conditions, since the problem is more a process than a thread
2864 issue. Problem reported by Stepan Kasal in:
2865 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2866 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2867 the test for 'install' more closely. Look at MKDIR_P first.
2868 Look in the PATH, and at /opt/sfw/bin.
2869 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2870 Don't bother to try mkdir -p, since we already check mkdir --version;
2871 just look at the version number. (There's no easy way to check
2872 for race-free implementations.)
2873 * tests/tools.at (autoconf: subdirectories): Adjust to above
2874 changes, since MKDIR_P now might end in "/mkdir -p".
2876 * doc/autoconf.texi (autoheader Invocation): Mention that the
2877 first arg of AC_DEFINE_UNQUOTED must be a literal.
2878 Problem reported by Ben Pfaff in
2879 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2881 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2882 * doc/autoconf.texi (Special Chars in Variables): New section.
2883 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2884 (Installation Directory Variables): Quote $(datadir) better.
2885 (Limitations of Builtins): Describe some of eval's trickiness.
2887 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2888 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2889 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2890 in front of every arg, not just trailing args. Quote apostrophes.
2891 (_AC_EVAL_ECHO): New macro.
2892 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2893 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2894 removed.
2895 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2896 exposed by quoting of eval argument. Put the command on line line
2897 so it logs better.
2898 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2899 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2900 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2901 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2902 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2903 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2904 Use eval more safely.
2905 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2906 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2907 to be replaced.
2908 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2909 lines, exposed by quoting of eval argument.
2911 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2912 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2914 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2915 initialization of `ac_cv_exeext', do not override it if it was
2916 already set, unless it was set to `no', for compatibility with
2917 Autoconf-2.13, and comment this.
2918 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2919 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2920 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2921 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2922 Document that this test may be overridden by setting
2923 `ac_cv_exeext'.
2925 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2927 Revert these two patches:
2929 2006-04-06 Eric Blake <ebb9@byu.net>
2930 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2931 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2932 2006-04-01.
2934 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2935 Clean up _AC_COMPILER_EXEEXT* macros.
2936 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2937 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2938 ac_file to the name of the default output file and call
2939 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2940 initial `rm' of the candidate files...
2941 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2942 the same list in subsequent `rm' calls, and for the temporary
2943 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2944 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2945 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2946 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2947 no longer needed) by libtool. Make it a cache check.
2948 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2949 copied here by mistake.
2950 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2951 _AC_COMPILER_EXEEXT.
2952 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2953 _AC_COMPILER_OBJEXT directly.
2954 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2956 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2958 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2959 Fix description of how the buggy `sed' works.
2961 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2963 Sync from Automake:
2965 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2966 ENOLCK. Only mention `make -j' when applicable. Only raise
2967 fatal errors when `make -j' is involved. Improve error message.
2969 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2971 * doc/autoconf.texi (Here-Documents): We now know more about
2972 the variable expansion in here documents bug.
2973 Thanks to Tim Rice and Stepan Kasal.
2975 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2976 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2978 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2980 * tests/autotest.at (Multiline command from M4 expansion):
2981 No failure to be expected if the shell quotes newlines in
2982 commands in the `set -x' output. Report by Tim Rice.
2983 * THANKS: Update.
2985 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2987 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2988 expansion in the here-documents used by config.status, as that
2989 runs afoul of the Korn shell version M-12/28/93d bug described in
2990 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2991 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2992 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2994 2006-05-23 Jim Meyering <jim@meyering.net>
2996 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2997 Fix typo introduced with 2006-04-02 change. It reversed the sense
2998 of the test.
3000 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3002 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
3003 ac_dB slightly, to save bytes in the script.
3004 Max out at 50 lines, rather than 96; this is more likely
3005 (though not guaranteed) to avoid obscure 'sed' failures.
3007 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3009 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
3010 `tr -d -' as bad option argument. Work around this by deleting
3011 an unrelated character.
3012 Report by Tim Rice <tim@multitalents.net>.
3014 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
3015 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3016 Stepan Kasal <kasal@ucw.cz>
3018 * doc/autoconf.texi (Particular Programs): Do not promise that
3019 we always prefer the GNU version of the program, and that we
3020 search according to PATH; both rules can have exceptions.
3021 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
3022 AC_PROG_SED. Move descriptions of limitations
3023 to the Limitations of Usual Tools section.
3024 (Limitations of Usual Tools) <sed>: Mention script length
3025 limitations with Solaris /usr/ucb/sed.
3026 <grep>: Fix wording for empty alternative. Mention that -c and
3027 -l should not be combined, and that -E and -F should not be
3028 combined.
3030 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3031 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3033 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
3034 limits in Solaris 8 /usr/ucb/sed by testing a long script.
3036 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3038 * doc/autoconf.texi (Defining Symbols): Literal parameter of
3039 AC_DEFINE is now passed to m4_pattern_allow.
3040 * NEWS: Mention that; likewise for AC_SUBST.
3041 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
3042 the parameter to m4_pattern_allow.
3043 * tests/tools.at: Add a check for that.
3045 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3047 * lib/autoconf/status.m4: Fix typos.
3049 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3051 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
3052 only the files that this macro generates.
3054 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3056 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
3057 the HP-UX sed limitation of 99 commands, labels do not count.
3058 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
3059 in the comment.
3060 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
3062 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3064 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3065 Import the following fix from coreutils:
3067 2006-01-13 Jim Meyering <jim@meyering.net>
3069 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
3070 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
3071 not double-quote uses of that variable, to accommodate the rare
3072 case in which getmntent is available in none of the libraries
3073 checked. This happens at least on FreeBSD 5.0.
3075 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
3077 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
3078 ac_config_guess, ac_config_sub, and ac_configure, since evidently
3079 some other programs unwisely rely on these undocumented vars.
3080 But put in warning comments about them.
3081 Problem reported by Ralf Wildenhues in
3082 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
3083 * NEWS: Document that these variables are intended to go away.
3085 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3087 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
3088 and set the language to C++ (analogous to the equivalent Fortran
3089 tests).
3091 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
3092 * doc/autoconf.texi (C++ Compiler): Document it.
3093 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
3094 * NEWS: Update.
3096 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
3098 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
3099 that caused config.status to generate 100-command sed scripts; the
3100 portable limit is 99.
3102 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3104 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
3105 variable `ac_d' instead of `d' to avoid infringing namespace.
3106 Report by Ralf Menzel.
3108 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
3110 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
3111 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
3112 * tests/tools.at (autoconf: subdirectories): New test, taken from
3113 the corresponding problem report by Ralf Wildenhues in:
3114 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
3116 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
3117 Quote some uses of shell variables if they might suffer unexpected
3118 globbing. This doesn't fix all instances of quoting problems that
3119 I found, just the easy ones that look safe.
3120 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
3121 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
3122 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
3123 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
3124 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
3125 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
3126 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
3127 Likewise.
3128 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
3129 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
3131 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3133 * bin/autoreconf.in ($help): Reword according to the manual.
3134 Suggested by Olly Betts.
3136 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
3137 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3139 * bin/autoreconf.in: Pass the directory argument to
3140 `require_configure_ac'. Fix comment.
3141 * tests/torture.at (Configuring subdirectories): Expose this.
3142 Reported by Olly Betts.
3144 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3146 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
3147 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
3148 Automake as follows:
3150 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
3151 `$configure_in' instead of `configure.in', to preserve
3152 directory component.
3154 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3156 * config/config.guess, config/config.sub, config/texinfo.tex,
3157 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
3159 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
3161 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
3162 test for C99 conformance; (bool) 0.5 is an integer constant
3163 expression, but (bool) -0.5 is not. Problem reported by Fedor
3164 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
3166 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
3168 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
3169 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
3170 Warn about obsolete install-sh files. Remove stray sentence
3171 fragment and fix cross reference.
3172 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
3173 install -d; this undoes the 2006-05-10 change.
3174 (MKDIR_P): Mark with AN_MAKEVAR.
3175 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
3176 that we don't require $INSTALL to be thread-safe. Move comments
3177 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
3178 of AC_PROG_INSTALL. Output a message saying that we're checking
3179 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
3180 MKDIR_P instead of AC_SUBST.
3181 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
3182 Special magic for MKDIR_P, too.
3183 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
3184 a dnl.
3185 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
3187 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
3189 Sync from Automake, as follows:
3191 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3192 * config/install-sh: Initialize IFS, so field splitting isn't
3193 turned off later.
3194 * config/mkinstalldirs: Likewise.
3195 * config/missing: Remove superfluous quotes. Replace all uses of
3196 `[' by `test', for consistency, and for..
3197 * config/missing (sed_minuso, sed_output): New variables.
3198 (autom4te, help2man, makeinfo): Use them. Unifies detection of
3199 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
3200 Fixes `missing' to detect `--output' for help2man. Fixes
3201 PR automake/483. Report by Dennis J. Linse.
3202 (autom4te): Document in `missing --help'.
3204 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3206 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
3207 * config/install-sh: Don't use 'path' to talk about file names,
3208 as per GNU coding standards. Close a race condition reported by Ralf
3209 Wildenhues and Stepan Kasal. There is still a race condition
3210 on hosts that predate Posix 1003.1-1992, but we can't help this.
3211 Don't mishandle weird characters like space on pre-Posix hosts.
3212 Invoke mkdir at most once per dir arg on pre-Posix hosts.
3213 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
3214 AC_PROG_MKDIR_P from AS_MKDIR_P.
3215 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
3216 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
3217 earlier editions are not (including Automake 1.8.3).
3218 Do not suggest mkinstalldirs for thread-safety.
3219 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
3220 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
3221 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
3222 presence of special characters and race conditions.
3223 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
3224 in Autoconf's name space.
3226 2006-05-10 Bruno Haible <bruno@clisp.org>
3227 and Paul Eggert <eggert@cs.ucla.edu>
3229 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
3230 from Automake with minor changes.
3231 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
3233 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3235 * config/install-sh: Update to Automake CVS version, as follows:
3236 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3237 * lib/install-sh: Simplify the expr implementation of dirname.
3238 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
3239 * lib/install-sh: Handle --, and diagnose unknown options.
3241 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3243 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
3244 `./autom4te' to create `./testsuite', since the `all' target
3245 will ensure its presence, but `installcheck' should not create
3246 the uninstalled wrappers.
3248 * tests/torture.at (Unusual Automake input files): Skip if we
3249 detect automake < 1.8.
3251 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3253 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
3254 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
3255 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
3256 * NEWS: Update.
3258 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3260 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
3261 munge (multiple) white space and other oddities.
3262 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
3263 single quotes in variable assignment.
3264 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
3265 and similar failures by adding multiple spaces, tabs, and other
3266 special characters.
3267 Report and different test suggested by Francesco Romani
3268 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
3270 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
3271 single quotes, we only need to search for single quotes; this
3272 both simplifies the search pattern, and makes us less
3273 susceptible to `echo' variations for arguments not containing
3274 single quotes.
3275 (_AC_ARG_VAR_VALIDATE): Likewise.
3277 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3279 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
3280 `$*' and IFS concatenation issue with traditional shells and
3281 bash-2.04. Report by Seanster@Seanster.com.
3283 2006-05-03 Bruno Haible <bruno@clisp.org>
3285 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
3286 precisely which Mac OS X versions have the od problem.
3288 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3290 * doc/autoconf.texi: Use @option systematically.

3293 and Bruno Haible <bruno@clisp.org>
3295 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
3296 about 'od'.
3297 (Integer Overflow): Mention the special case of integer division
3298 overflow.
3300 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3302 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
3303 traditional shells like the Solaris one that do not use the
3304 first IFS character for assembling `$*'.
3305 Prompted by a related report from autoconf_bug@nro.ca.
3307 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
3308 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3310 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
3311 Mention more problems with the -e option.
3313 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3315 * NEWS: Typo.
3316 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
3318 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
3319 in URLs to improve DVI formatted output (requires texinfo 4.6).
3320 (System Services, Systemology, Shellology): Likewise.
3321 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
3322 output.
3324 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
3325 continuous text.
3326 (Runtime): Fix macro argument names to match description:
3327 `action-if-found' -> `action-if-true' and similarly.
3328 (Obsolete Macros): Likewise.
3329 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
3330 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
3331 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
3333 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3335 * doc/autoconf.texi (Limitations of Make): Clean up markup.
3337 * ChangeLog: Typo.
3338 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
3339 DVI output.
3341 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3344 /bin/sh set unsorted output.
3345 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
3346 * tests/local.at: Likewise.
3348 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
3350 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
3351 (Integer Overflow, Null Pointers, Buffer Overruns):
3352 (Floating Point Portability, Exiting Portably): New sections.
3353 (Writing Test Programs): Fix some langauge. Recommend exiting
3354 with status 1, not merely nonzero. Clarify exit declaration.
3355 (Run Time): Move C exit status stuff to new Exiting Portably section.
3356 (Systemology): Mention Posix and levenez. Update v7 reference.
3357 (Portable Shell): Mention the Posix shell.
3359 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3361 * bin/autoconf.as (me): Replace by as_me.
3363 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
3365 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
3366 since as_me isn't set yet.
3368 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3370 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
3371 a few minor bugs in this area.
3373 * doc/autoconf.texi (Programming in M4sh): Comment out the
3374 documentation of AS_BASENAME, for now.
3375 (Shell Substitutions): Do not use AS_DIRNAME in an example.
3376 (Limitations of Builtins) <basename>: Do not refer to
3377 AS_BASENAME.
3378 * bin/autoconf.as (me): Don't use AS_BASENAME.
3379 (dir): Remove the unused variable.
3380 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
3381 AS_DETECT_REQUIRED. All uses changed.
3382 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
3383 All uses changed.
3384 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
3385 (AS_BASENAME): Use "basename --" to protect against leading "-".
3386 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
3387 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
3388 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
3389 (_AS_DIRNAME_PREPARE): Likewise.
3390 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
3391 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
3392 (AS_DIRNAME): Use "dirname --".
3394 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3396 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
3397 of "run time" and "run-time" changed to "runtime", for consistency.
3398 * lib/autoconf/fortran.m4: Likewise (in comment).
3399 * lib/autoconf/functions.m4: Likewise.
3400 * lib/autoconf/general.m4: Likewise.
3401 * lib/autoconf/headers.m4: Likewise.
3403 * doc/autoconf.texi (Run Time): Document the exit status situation
3404 with more accuracy and detail.
3406 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3408 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
3409 Archive is not officially `GNU' any more. Update URL.
3410 (Defining Directories): Likewise
3411 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
3413 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3415 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
3416 newline from the `trap' code to finish `config.log'; the NetBSD
3417 /bin/sh resets the exit status after an empty command, as
3418 documented in doc/autoconf.texi.
3419 Reported by Dalibor Topic <robilad@kaffe.org>.
3421 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
3423 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
3424 Suggested by Bruno Haible.
3426 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
3428 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
3429 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
3430 Instead, just list the shells that we know work.
3431 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
3432 changed. Be more cautious about the _cv_ variable.
3433 * tests/tools.at (Syntax of the shell scripts): Check the
3434 _cv_ variable once, at first, to avoid an internal autoconf error
3435 when sh -n does not work.
3437 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3439 * lib/Autom4te/FileUtils.pm: Sync from Automake.
3441 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
3443 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
3444 use ">&-" since we're only 99.999% sure that this is portable,
3445 and since the MinGW bug is fixed in a different way.
3446 * lib/autotest/general.m4 (AT_INIT): Likewise.
3448 2006-04-16 Stepan Kasal <kasal@ucw.cz>
3450 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
3451 before opening config.log, to avoid hitting a bug on MinGW.
3453 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
3455 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
3456 AS_MESSAGE_LOG_FD before reopening it onto the log file.
3457 This works around a MinGW bug reported by Eric Paire.
3458 Make sure that all writes to the log file append to it,
3459 rather than possibly losing data.
3460 * lib/autotest/general.m4 (AT_INIT): Likewise.
3462 2006-04-14 Stepan Kasal <kasal@ucw.cz>
3464 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
3465 description.
3467 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3469 * NEWS: Update.
3471 * configure.ac (AC_INIT): Bump to 2.59d.
3473 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3475 Version 2.59c.
3477 * Makefile.maint (news-date-check): Do not require a leading `*'
3478 before the release date in NEWS.
3480 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3481 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3483 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
3484 the instantiated file do not contain the string 'datarootdir'
3485 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
3486 @mandir@, replace the reference '${datarootdir}' by the value.
3487 * tests/torture.at (datarootdir workaround): New test.
3488 * NEWS: Advertise this temporary fixup.
3489 Based on a patch by Bruno Haible, reported and analyzed by
3490 Paul Eggert and Noah Misch.
3492 2006-04-12 Eric Blake <ebb9@byu.net>
3494 * tests/autotest.at (Debugging a failed test): Fix comment.
3496 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3498 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
3499 all the changes since 2006-04-07.
3501 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3503 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
3504 succeeded, but `ln -s file dir' failed, take care to remove the
3505 leftover target before the next test, to prevent its spurious
3506 failure; also make sure `ln file dir' works before selecting it.
3507 Thanks to Keith Marshall for pointing this out.
3508 * THANKS: Update.
3510 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
3511 assignments in `at_debug_args', so that we put them correctly
3512 in the `run' script.
3513 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
3514 Reported by Eric Blake.
3516 2006-04-11 Eric Blake <ebb9@byu.net>
3518 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
3519 top-level tests after micro-suite has been run. Used in...
3520 (Debugging a successful test, Debugging script and environment),
3521 (Debugging a failed test): ...these new tests. The first of these
3522 is fixed by...
3523 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
3524 macro, split out from...
3525 (AT_INIT): ...here, so that using -d also generates a run script.
3526 Document that -d inhibits top-level logging.
3527 * doc/autoconf.texi (testsuite Invocation): Document that -d only
3528 inhibits top-level logging; debug scripts are created.
3530 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
3531 check.
3532 * tests/autotest.at (Empty test, Empty check): New test to check it.
3534 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
3535 from gcc.
3537 2006-04-10 Stepan Kasal <kasal@ucw.cz>
3539 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
3540 the files if a problem appears. Make the empty *.at files
3541 read-only, too. Proposed by Ralf Wildenhues.
3543 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3545 * config/Makefile.am: Add comment to force updated Makefile.in.
3547 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
3548 space only patch to this file, this patch causes the Makefile.in
3549 files that include freeze.mk to be updated, and thus have a
3550 newer time stamp again, which in turn makes a pristine CVS
3551 checkout have correct time stamps.
3553 * Makefile.maint (cvs-sv): New macro, to be used..
3554 (config.guess-url_prefix, config.sub-url_prefix)
3555 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
3556 point to CVS text checkout of Gnulib files.
3557 (copyright-check): Bump current year.
3558 (announcement): Do not hard-wire `./announce-gen'.
3559 (cvs-update): Propagate failures of `cvs' and `move-if-change'
3560 correctly.
3561 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
3562 `chmod +x'.
3563 (wget_files): Update config.guess, config.sub, texinfo.tex by
3564 `wget-update', now that their URLs work again.
3566 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3568 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
3569 Problem noted by Paul D. Smith.
3571 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3573 * doc/autoconf.texi: Remove unused words from word list.
3574 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
3575 .x-sc_trailing_space: New files.
3577 * doc/standards.texi: Sync from gnulib.
3579 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
3580 `LIBOBJDIR' as experimental.
3582 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
3583 with a target directory; it's internally implemented as `cp'
3584 anyway, but since Autoconf advertises the possibility to use
3585 a target directory when LN_S is `ln -s', we need to find out.
3586 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
3587 analyzed by Keith Marshall <keith.marshall@total.com>.
3589 * THANKS: Update.
3591 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3593 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
3594 confdefs.h as-is. In general, if it has backslash-newline or the
3595 like, then it doesn't work either to sort or to remove empty
3596 lines.
3598 2006-04-09 Stepan Kasal <kasal@ucw.cz>
3600 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
3602 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
3604 * lib/autom4te.in (Automake-preselections): Preselect
3605 _AM_SUBST_NOTMAKE.
3607 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3609 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
3610 apostrophe within a single-quoted string, as this is the usual
3611 tradition and is easier to read than '"'"'. Don't rely on the
3612 shell treating "$/" like '$/'. Use a more-consistent indenting
3613 style for the trap.
3615 2006-04-09 Eric Blake <ebb9@byu.net>
3617 * tests/autotest.at (Backquote command substitution),
3618 (Multiline backquote command substitution): Remove mistaken
3619 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
3620 applied...
3621 (Parenthetical command substitution, Multiline parenthetical
3622 command substitution): here.
3624 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3626 Import macros from gnulib (often changing their name).
3628 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
3629 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
3630 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
3631 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,
3632 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T,
3633 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
3634 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
3635 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
3636 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
3637 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
3638 The manual mentions Gnulib more prominently.
3639 * doc/autoconf.texi (Gnulib): New node.
3640 (Pointers): Add Gnulib URL.
3641 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
3642 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
3643 Gnulib section.
3644 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
3645 suggest a #define rather than a typedef for _Bool, and mention
3646 Gnulib rather than trying to substitute stdbool code.
3647 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
3648 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
3649 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
3650 AC_STRUCT_DIRENT_D_TYPE.
3651 (Particular Types): Mention stdint.h and inttypes.h as standard
3652 headers too.
3653 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
3654 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,

3701 Revert the patch from 2006-04-01 and only improve
3702 _AS_DETECT_BETTER_SHELL:
3704 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
3705 skip nonexistent directories.
3706 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
3707 only shell candidates which exist.
3708 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
3709 * lib/autotest/general.m4 (AT_INIT): No need to give three
3710 parameters to _AS_PATH_WALK.
3712 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
3713 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3715 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
3716 distinguish m4sugar macros.
3717 * tests/tools.at (autoupdating with aclocal and m4_include):
3718 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
3719 test case by Noah Misch <noah@cs.caltech.edu>.
3721 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3723 Revert my change from 2006-03-17, in other words:
3724 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
3725 and DUALCASE=1.
3726 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
3727 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
3728 it is set.
3730 2006-04-07 Eric Blake <ebb9@byu.net>
3732 * doc/autoconf.texi (Programming in M4sh): Document that
3733 AS_MKDIR_P exits the script on failure.
3734 * lib/autotest/general.m4: Remove redundant AS_ERROR.
3736 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3738 * config/elisp-comp, config/install-sh, config/mdate-sh,
3739 config/missing, config/mkinstalldirs: Sync from Automake.
3741 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
3742 from Automake.
3744 * doc/make-stds.texi: Sync from gnulib.

3748 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3749 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced

3755 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3757 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
3758 whether `set' quotes correctly: redirect stderr of the tested
3759 `set', and use a subshell, for Ultrix; use `sed' instead of
3760 `grep' for zsh `set' which may write binary output; match only
3761 at the beginning of a line, to avoid false positives.
3762 In order to avoid false positives by unrelated variables with
3763 multiline content, put the dump algorithm in a subshell and
3764 unset all variables containing newlines (except some which are
3765 special to the shell). Warn about cache variables that are
3766 unset.
3768 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3770 * config/config.guess, config/config.sub, config/texinfo.tex:

3779 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
3780 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
3781 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
3782 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
3784 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
3785 shell issue with double-quoted command substitutions of native
3786 commands.

3807 * tests/Makefile.am (maintainer-check-posix):
3808 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
3810 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
3811 ac_config_<foo>s again, sometimes normalized, sometimes not.
3812 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
3813 (AC_CONFIG_COMMANDS): Do not do so here.
3814 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
3815 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
3816 2005-07-25 rewrite. Noticed by Noah Misch.
3818 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
3819 _AC_PRESERVE_HELP_ORDER, ...
3820 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
3822 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
3823 inside m4_expand_once; it is redundant.
3825 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
3826 for --help from Cygnus `configure.'
3828 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

3838 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
3839 Noah Misch <noah@cs.caltech.edu>
3841 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
3842 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
3843 * doc/autoconf.texi (Help Formatting): New node.
3844 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
3846 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3848 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
3849 lib/autoconf/specific.m4, lib/autoconf/status.m4,
3850 lib/autoconf/types.m4, lib/autotest/general.m4,
3851 tests/mktests.sh, tests/torture.at: White space cleanup:

3861 empty test suite works.
3862 * tests/autotest.at (Empty test suite): Remove xfail.
3864 2006-04-05 Noah Misch <noah@cs.caltech.edu>

3867 TAGS to ac_config_<foo>s.
3868 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
3869 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
3870 normalizing it, consistent it with previous releases.
3871 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
3873 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3875 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
3876 Use simplified args that Eric Blake originally suggested.
3878 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
3880 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
3881 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
3882 Use 'comm' rather than N instances of grep; this also fixes a bug
3883 whereby substrings were incorrectly matched, causing us to not
3884 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
3885 (exclude_list): Exclude empty macros.
3886 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
3888 Use awk rather than grep -E or egrep, to avoid

3891 Switch from grep to awk syntax.
3892 (ac_exclude_script): Renamed from ac_exclude_egrep.
3893 (au_exclude_script): Renamed from au_exclude_egrep.
3895 2006-04-04 Noah Misch <noah@cs.caltech.edu>
3897 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
3898 a subdirectory subject to Cygnus `configure'.
3899 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
3901 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
3902 report request when we have no AC_PACKAGE_BUGREPORT.
3904 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3906 * THANKS: Update.

3912 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
3913 typedef'ed restricted pointer, to catch a compiler bug on
3914 HP-UX 11.x, and fix warnings so it passes with -Werror.
3915 (_AC_PROG_CC_C99): Likewise.
3916 Reported by Albert Chin <china@thewrittenword.com>.

3936 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
3937 to log, point to testsuite output tree.
3939 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>

3969 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3970 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3971 ac_file to the name of the default output file and call
3972 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3973 initial `rm' of the candidate files...
3974 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3975 the same list in subsequent `rm' calls, and for the temporary
3976 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3977 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3978 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3979 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3980 no longer needed) by libtool. Make it a cache check.
3981 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3982 copied here by mistake.
3983 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3984 _AC_COMPILER_EXEEXT.
3985 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

4018 Autoconf version number despite a zero- or one-argument AC_INIT.
4020 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
4021 subordinate tools.
4022 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
4023 * doc/autoconf.texi (autoreconf Invocation): Document it.
4025 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
4026 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.

4037 the correct lines of the input file by subtracting..
4038 (_au__first_line): ..this new definition.
4040 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
4041 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
4042 Remove stray newline in output.
4043 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
4044 AC_DEFUN this for autoconf, including the obsoletion diagnose.
4045 Fixes autoupdating of code where the replacement output contains
4046 m4sugar macros.
4047 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
4048 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

4050 * tests/tools.at: Several new tests for all of this.
4051 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
4052 hairy details.
4053 The AC_LANG_SAVE issue was reported against Libtool by
4054 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
4055 Kristian Kvilekval <kris@cs.ucsb.edu>.
4057 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4059 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
4060 switch all of them on and of when necessary. Fixes the bug when
4061 m4sugar macros (e.g., m4_define) were expanded after the first
4062 automatic update (e.g., after AC_PREREQ or AC_INIT).
4064 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

4611 (Coding Style): y is like s with respect to / and ,.
4612 (Limitations of Usual Tools): Document the weird restrictions
4613 that Posix has about { }. Use better quoting.

4701 Factor functionality to..
4702 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
4703 `AC_SUBST($1)' in the public version.
4704 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
4705 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

4758 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
4759 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
4760 by the function rather than ignoring it.
4761 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
4762 comparing its address. Intel's interprocedural optimization was
4763 outsmarting the old heuristic. Problem reported by
4764 Mikulas Patocka.

4768 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

4775 2005-10-04 Stepan Kasal <kasal@ucw.cz>
4777 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
4778 before removing it (chmod -R u+rwx); there are three instances of this.
4780 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4781 Stepan Kasal <kasal@ucw.cz>
4783 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
4784 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
4785 make its content writable before removing it. Remove an errorneous
4786 comment from the end, where the logs of the failed tests are copied
4787 to the main log file.
4789 2005-09-27 Stepan Kasal <kasal@ucw.cz>
4791 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
4792 in case the computer is too quick. Double quote the configure.ac
4793 snippets.
4795 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
4796 problems if the testsuite were running too fast.
4798 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4800 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4801 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4802 (which belong to Xt, not X itself). See Debian bug 327655.
4803 * NEWS: Mention this.
4805 2005-09-07 Stepan Kasal <kasal@ucw.cz>
4807 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
4809 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
4811 * config/move-if-change: Don't output "$2 is unchanged";
4812 suggested by Ben Elliston. Handle weird characters correctly.
4814 2005-09-06 Stepan Kasal <kasal@ucw.cz>
4816 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
4817 calls, so that the final expansion of this macro is shorter.
4818 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
4819 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
4820 the cleanup there. Use AS_VAR_* macros, to be more general.
4821 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
4823 * lib/autoconf/general.m4: Use AS_IF where appropriate.
4825 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
4827 2005-09-01 Stepan Kasal <kasal@ucw.cz>
4829 * doc/autoconf.texi (Configuration Headers): Add an index entry
4830 for AH_HEADER.
4832 2005-08-26 Pavel Roskin <proski@gnu.org>
4834 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
4835 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
4836 running xmkmf.
4838 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
4840 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4841 The previous patch didn't work, so try a better one.
4843 2005-08-26 Stepan Kasal <kasal@ucw.cz>
4845 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
4846 in the example. Reported by Bruno Haible.
4847 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
4848 "if $undefined_var;" succeeds with my shell.
4850 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
4851 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
4852 but change the m4_divert_text to m4_divert_once.
4854 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
4856 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4857 Work around bug in Solaris /usr/xpg4/bin/awk.
4858 The bug is present in at least Solaris 8 through 10.
4860 2005-08-24 Stepan Kasal <kasal@ucw.cz>
4862 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
4863 some evil values and relying on the fact that $* concatenates the
4864 parameters by the first character from IFS.
4866 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4867 Stepan Kasal <kasal@ucw.cz>
4869 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
4870 first header appears, define AH_HEADER.
4871 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
4872 Update limitations about when to call AC_CONFIG_HEADERS.
4873 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4874 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4875 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4876 ``Configuration Actions''; fix their index entries.
4878 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4879 options correctly. Process N-M as M-N if M is smaller than N.
4880 Process ranges correctly so that N-N will run only N.
4881 Sort and uniquify the tests that will be run. If there is more
4882 than one test, reinsert the banners for the tests.
4883 * tests/autotest.at (Keywords): Unmark XFAIL.
4885 2005-08-23 Stepan Kasal <kasal@ucw.cz>
4887 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
4888 before passing the macro name to AH_TEMPLATE.
4890 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
4891 now opens log after option processing; in particular, --version
4892 and --help do not touch config.log.
4894 * Makefile.maint: Revert the change from 2005-08-12.
4896 2005-08-22 Stepan Kasal <kasal@ucw.cz>

4902 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4904 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
4905 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
4906 Language cleanup.
4908 * doc/autoconf.texi (Defining Symbols, Changed Results):
4909 Prepend to LIBS, not append, in examples.
4911 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4913 When building in place, set srcdir="."; suggested by Tim Van Holder.
4915 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4916 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4917 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4918 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
4919 does not mean "no --srcdir option".
4921 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4923 * tests/autoscan.at (autoscan): New file.
4924 * tests/suite.at: Use it.
4925 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
4926 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
4928 * tests/autotest.at (Keywords): Test keywords combinations.
4930 2005-08-12 Stepan Kasal <kasal@ucw.cz>
4932 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
4933 add "2>&1"; gzip 1.2.4 prints help on stderr.
4935 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4937 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
4938 was pushdef'ed twice while popped only once. Push it only once.
4939 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
4941 2005-07-26 Stepan Kasal <kasal@ucw.cz>
4943 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

4948 * Makefile.maint: Update from Bison.
4950 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
4951 "<tab>" in comment, so that the point is understandable.
4953 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4955 Rewrite substantial part of lib/autoconf/status.m4.
4956 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4957 and CONFIG_COMMANDS are not processed in four separate loops.
4958 Instead, there is one main loop. This alows that the common code
4959 is expanded only once, thus config.status (and configure) is smaller.
4961 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4962 the AC_LIST_FILES and cousins macros are no longer used.
4964 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4965 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4966 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4967 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4968 contain the initialization, nor the for loop, nor the associated
4969 commands; all these go to ...
4970 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4971 _AC_OUTPUT_CONFIG_STATUS.
4972 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4973 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4974 (_AC_OUTPUT_FILE): The creation of the sed script ...
4975 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4976 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4977 _AC_OUTPUT_MAIN_LOOP.
4978 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4979 _AC_CONFIG_COMMANDS): Use ...
4980 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4981 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4982 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4983 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4984 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4985 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4986 ... new macros.
4987 (_AC_CONFIG_UNIQUE): Update.
4988 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4989 Replaced by this ...
4990 (_AC_LIST_TAGS): ... new common macro.
4991 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4992 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4993 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4994 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4995 this didn't belong to the `config commands' section.
4996 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4997 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4998 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4999 to the `config commands' section either.
5000 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
5001 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
5003 ... and many changes to the comments nearby.
5005 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
5006 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
5007 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5008 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
5009 (#define header templates): The comment at the top of the generated
5010 header now includes the name(s) of the source file(s).
5012 Several unrelated small changes:
5014 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
5015 parameter to AC_DIAGNOSE.
5016 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
5017 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
5018 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
5019 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
5020 with AU::AC_OUTPUT.
5021 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
5022 in AC_OUTPUT doesn't double-quote it either.
5023 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
5024 parameters.

5047 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
5048 change eliminates it. Problem reported by Alexandre Duret-Lutz.
5049 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
5050 (AC_ARG_VAR): ... here.
5051 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
5052 target_alias.

5061 a loop to assign all ac_env_* and ac_cv_env_* variables.
5062 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
5063 to INIT_PREPARE.
5064 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
5065 its value to shell variable ac_precious_vars and call
5066 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
5067 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call

5104 versions of autoconf.
5106 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
5108 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
5109 Problem reported by Patrick Welche.

5113 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
5114 sed substitution command, so that we allow | in program prefixes

5117 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
5118 configure_input, top_builddir, srcdir, etc.
5119 * lib/autotest/general.m4 (AT_INIT): Likewise, for
5120 PATH_SEPARATOR in AUTOTEST_PATH.
5122 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

5130 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
5131 directories with weird names. Apparently some people like living

5155 Likewise for --header; moreover, recognize --he and --h as shortcuts
5156 for --help in that case.
5158 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
5159 matches the order of execution. No code changed.

5181 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
5182 (AC_SUBST): Call it.
5183 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
5184 the directory specific variables; but don't call it for configure_input.
5186 2005-06-28 Derek Price <derek@ximbiot.com>
5188 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
5189 addition.
5191 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
5193 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
5194 directory have inherent problems with special characters like spaces,

5213 because we really don't support spaces and suchlike in dir names.
5214 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
5215 Don't worry about backslashes in srcdir; it can't happen now.

5243 b, t, r, w commands require single space, while : cannot have any.
5244 (Special Shell Variables): Fix sed code this in the example.
5245 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
5246 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
5248 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
5249 expand to the empty list. Don't use two pairs of m4_changequote,
5250 it's not necessary.
5252 2005-06-20 Derek Price <derek@ximbiot.com>
5254 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.

5258 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
5259 * doc/autoconf.texi:
5260 Don't mention Solaris versions so much, if a
5261 problem is common to all extant versions of Solaris. Say "SunOS
5262 4" instead of "SunOS" for SunOS 4.
5263 (awk): Mention more of the limitations of traditional Awk.
5264 (cat): Don't talk about cat -v.
5266 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

5277 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
5278 Use shell builtins rather than 'expr', to work around expr bug.
5280 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
5282 * doc/autoconf.texi: "filesystem" -> "file system".
5283 "behaviour" -> "behavior".

5296 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
5297 quotes and backslashes. Patch from Derek Price.

5302 AS_TR_SH.
5304 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
5306 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
5307 -u, since it outputs chatter if the input files are the same.
5308 Problem reported by Ralf Menzel.
5310 2005-06-08 Derek Price <derek@ximbiot.com>
5312 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
5313 renaming them since they are about to be redefined anyhow.
5315 2005-06-08 Derek Price <derek@ximbiot.com>
5317 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
5318 redefined M4 macros to this node. Document m4_include & m4_sinclude.
5319 Move m4_undefine to alphabetical order.
5321 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
5323 * README: Recommend GNU M4 1.4.3 or later.
5324 * doc/autoconf.texi (Introduction): Likewise.
5325 Reword to avoid some formatting glitches.
5326 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
5327 Clarify explanation of HP compiler bug.
5328 Redo example output tp match current CVS snapshot.
5329 Use @example.org in email addresses when the examples
5330 might get inadvertently cut-and-pasted into user code.
5331 Remove example of autom4te usage that doesn't seem to work now.
5332 Use modern AC_INIT (except when the example is meant to be
5333 shown with Autoconf 2.13).
5334 Update ksh info for Solaris 9 and later.
5335 KB -> kB.
5336 Modernize description of Automake versions a bit.
5337 Don't claim a future version of Autoconf is near.

5344 Reword to avoid some formatting glitches.
5345 * doc/installt.exi: Reword to avoid some formatting glitches.
5347 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
5348 Tru64 ksh pattern matching bug. Reported against Libtool by
5349 Albert Chin <libtool@mlists.thewrittenword.com> and
5350 Nicolas Joly <njoly@pasteur.fr>.
5352 2005-06-06 Stepan Kasal <kasal@ucw.cz>
5354 m4_cdr of one-member list was [[]] (one-member list containing an
5355 empty string) instead of [] (an empty list. Callers were skewed to
5356 match this misbehaviour. As a consequence of this:
5357 - m4_foreach([x], [], [foo]) expanded to `foo', while
5358 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
5359 This bug has been fixed:
5361 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
5362 expand to an empty string; print error msg if called without
5363 an argument list.
5364 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
5365 misbehaviour; handle [] and [[]] correctly.

5373 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
5375 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
5376 swallow records with more than 99 fields.
5377 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
5378 parse the long line.
5380 2005-06-04 Stepan Kasal <kasal@ucw.cz>
5382 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
5383 swallow literals longer than 399. Reported by Ralf Wildenhues.
5384 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

5387 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
5389 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
5390 to gfortran, and make these the first two compiler names
5391 checked (following the general autoconf preference for gcc).
5393 2005-06-03 Stepan Kasal <kasal@ucw.cz>
5395 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
5396 (DISTCLEANFILES): Remove $(check_SCRIPTS).
5397 (testsuite): Make sure autotest.m4f is up-to-date before using it.

5401 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
5402 expression of unbounded size when processing the --list
5403 option. This runs afoul of a limit of 399 bytes per regular
5404 expression on AIX. Problem reported by Ralf Wildenhues.

5413 Reword description of line replacement.
5415 2005-05-31 Dan Manthey <dan_manthey@partech.com>
5417 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
5418 now contain newlines, and substituted files must be referenced on
5419 a line alone; the sed scripts to substitute them are now very
5420 different.
5421 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
5422 commands can be put in a sed script portably.
5423 * doc/autoconf.texi (Setting Output Variables): Document above

5436 classes in shell scripts. The test was too brittle.
5438 2005-05-25 Stepan Kasal <kasal@ucw.cz>
5440 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
5441 * doc/autoconf.texi (Limitations of Builtins): Document this
5442 limitation.
5444 2005-05-24 Stepan Kasal <kasal@ucw.cz>

5471 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
5472 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
5473 (ac_top_builddir): ... this ...
5474 (ac_top_build_prefix): ... to this; the old name is also kept, for
5475 backward compatibility.
5476 (ac_top_builddir_sub): New variable, without the trailing slash,
5477 always nonempty.
5478 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
5479 * doc/autoconf.texi (Configuration Actions): Rename
5480 ac_top_builddir to ac_top_build_prefix.
5481 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
5482 at_top_builddir to at_top_build_prefix.
5483 * lib/autotest/general.m4 (AT_INIT): Likewise.
5485 2005-05-20 Stepan Kasal <kasal@ucw.cz>
5487 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
5488 of confdefs.h .
5490 2005-05-17 Stepan Kasal <kasal@ucw.cz>
5492 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
5493 argument to m4_foreach. I guess it was necessary in the past,
5494 but I think it's a no-op now.
5496 2005-05-17 Stepan Kasal <kasal@ucw.cz>
5498 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
5499 ``cat <<_ACEOF'' commands to one.
5500 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
5501 * lib/autoconf/status.m4: On various places, use expr instead of
5502 ``echo|sed.''
5503 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
5504 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
5505 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
5506 a range.
5507 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
5508 the wrong patterns between ``case'' and ``esac.'' The previous
5509 code had false positives.
5511 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
5513 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
5514 as on 2005-05-02.
5515 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
5516 Mention LIBOBJDIR.

5556 2005-05-13 Stepan Kasal <kasal@ucw.cz>
5558 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
5559 check.
5560 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
5561 enough arguments, similarly as in m4_bpatsubsts.
5563 2005-05-12 Stepan Kasal <kasal@ucw.cz>
5565 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
5566 of absolute paths.
5568 2005-05-11 Stepan Kasal <kasal@ucw.cz>
5570 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
5571 for absolute directory names in one loop.
5572 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
5573 abbreviations of --version and --debug.
5575 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
5577 * doc/autoconf.texi (Autoconf Language): Be more precise about
5578 quoting rules. Problems noted by Stepan Kasal.
5579 Also, throughout this document, be more careful about white space.
5580 "blank", "white space", and "space" all have different meanings
5581 and we should be careful to say what we mean.
5583 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
5585 Fix C++ related problems reported by Werner Lemberg.
5586 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
5587 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
5588 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
5589 avoid problems with C++ and throw.
5590 * tests/compile.at: .cpp, not .cc.
5592 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
5594 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5596 * doc/autoconf.texi (Generic Functions): Typos.
5598 2005-05-02 Gary V. Vaughan <gary@gnu.org>
5600 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
5601 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
5602 set by latest automake.
5604 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
5606 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
5607 outputs 0 on GNU/Linux these days.
5609 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
5611 * doc/autoconf.texi (Autoconf Language): Add more description
5612 about quoting heuristics.
5613 (Limitations of Builtins): Describe "set -" problems.
5615 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5617 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
5618 not newline.
5620 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
5621 by AC_DEFINE; it was a mistake.
5622 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
5624 2005-04-25 Stepan Kasal <kasal@ucw.cz>
5626 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
5628 2005-04-22 Stepan Kasal <kasal@ucw.cz>
5630 * doc/autoconf.texi (External Software): Quadrigraphs are not
5631 processed correctly in AS_HELP_STRING; avoid this in the examples.
5632 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
5633 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
5634 comment and reduce m4_default([foo], []) to [foo].
5635 (m4_strip): Update the explanation.
5637 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
5639 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
5640 Remove core.conftest.* too; it's generated by Tru64 5.1.
5641 Problem reported by Jennis Pruett.
5642 * lib/autoconf/functions.m4
5643 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
5644 Don't bother to remove core files; AC_RUN_IFELSE should do that
5645 for you.
5647 2005-04-19 Stepan Kasal <kasal@ucw.cz>
5649 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
5651 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
5653 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
5654 Report from Horst Wente.
5656 2005-04-15 Stepan Kasal <kasal@ucw.cz>
5658 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
5659 the comment.
5661 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
5663 * doc/autoconf.texi (External Software, Package Options): Add
5664 examples showing how to implement --with-* and --enable-* options.
5666 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
5668 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
5669 as well as configure.in. Problem reported by Gregorio Guidi.
5671 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
5673 * doc/autoconf.texi (Particular Functions): Use gnulib's current
5674 pattern for alloca snippet.
5676 2005-04-04 Stepan Kasal <kasal@ucw.cz>
5678 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
5680 2005-04-01 Stepan Kasal <kasal@ucw.cz>
5682 * doc/autoconf.texi (Generic Programs): Fix a typo.
5684 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
5686 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
5687 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
5689 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5691 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
5692 Merge `-z option' as well for the benefit of Solaris link flags. Pass
5693 whole-archive (-zallextract, -zdefaultextract) options in the hope of
5694 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
5695 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
5697 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
5699 * NEWS: The configure command now warns you if you attempt to use
5700 a directory whose name contains a special character like space,
5701 newline, or "\".
5702 * doc/autoconf.texi (Installation Directory Variables): Allow
5703 "," in file names. Do not use \@; it's not a portable regexp.
5704 * bin/Makefile.am (edit): Likewise.
5705 * lib/Makefile.am (edit): Likewise.
5706 * tests/Makefile.am (edit): Likewise.
5707 * tests/semantics.at: Likewise.
5708 * tests/torture.at: Likewise.
5709 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
5710 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
5711 * doc/autoconf.texi (File System Conventions): Warn about
5712 unportable file names.
5713 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
5714 (AC_INIT): Use it.
5715 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
5716 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
5717 ac_pwd, and quote srcdir.
5718 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
5720 * doc/autoconf.texi: Fix some systematic formatting problems.
5721 ".)" needs a following @: if not at the end of a sentence, and
5722 similarly for "!)". "etc." should be preceded by a comma.
5723 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
5725 2005-03-22 Bruno Haible <bruno@clisp.org>
5727 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
5728 argument is often called 'build-aux'.
5730 2005-03-07 Stepan Kasal <kasal@ucw.cz>
5732 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
5733 macro AC_TRY_LINK is obsolete.
5734 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
5735 `AC_CONFIG_FILES'.
5737 2005-02-24 Stepan Kasal <kasal@ucw.cz>
5739 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
5740 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
5741 from a Common Lisp's `cl'.
5742 (AC_PROG_CXX): Behave according to the documentation: don't
5743 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
5744 make the variable CCC precious; use `cl.exe', not `cl'.
5746 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5747 Alexandre Duret-Lutz <adl@gnu.org>
5749 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
5750 /dev/null, as "configure" shouldn't read stdin, and this insulates
5751 us from problems (e.g., when testing for "cl"). Also, do this
5752 redirection before invoking "hostname" or "uname", and keep the
5753 original input stream available via...
5754 (AS_ORIGINAL_STDIN_FD): ... this new macro.
5755 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
5756 bother with "</dev/null" since it's now done at the top of
5757 'configure'.
5758 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
5759 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5760 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5761 * doc/autoconf.texi (File Descriptor Macros): New section.
5762 (Printing Messages): Mention it.
5763 * tests/base.at (Input/Output): New test.
5765 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5767 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
5768 newline if neither \c nor -n work, as that would output two
5769 newlines. Prefer -n to \c. Reported by Stepan Kasal.
5771 2005-02-12 Stepan Kasal <kasal@ucw.cz>
5773 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
5774 This causes that any required macros inside will get before the if.
5775 * doc/autoconf.texi (autom4te.cache): A typo.
5777 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
5779 Undo previous change, except keep the change to
5780 lib/autoconf/programs.m4 that replaced grep with shell
5781 pattern-matching. This is because net-snmp configure reads stdin.
5782 Reported by Noah Misch.
5784 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
5786 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
5787 from /dev/null, as "configure" shouldn't read stdin, and this
5788 insulates us from problems (e.g., when testing for "cl").
5789 Suggested by Alexandre Duret-Lutz. Also, do this redirection
5790 before invoking "hostname" or "uname".
5791 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5792 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
5793 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
5794 "</dev/null" since it's now done at the top of 'configure'.
5795 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5796 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5797 Also, replace grep with shell pattern-matching, to save a process.
5799 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
5801 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5802 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
5803 avoid thinking that Allegro Common Lisp's "cl" command is a C++
5804 compiler.
5806 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
5808 * doc/autoconf.texi (Limitations of Usual Tools): Document that
5809 grep -q isn't portable. Improve grep -s explanation.
5810 Problem reported by Dan Manthey.
5812 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
5814 * doc/autoconf.texi (Special Shell Variables): Clarify
5815 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
5817 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
5819 * doc/autoconf.texi: Use @acronym for DJGPP.
5820 Fix some @code's that should have been @env's, and vice versa.
5821 Sort environment variable names.
5822 Mention that shells no longer inherit IFS.
5823 Don't recommend PATH_SEPARATOR=';' so strongly.
5824 Mention that $RANDOM might expand to the empty string.
5825 "symlink" and "soft link" -> "symbolic link".
5826 Improve mktemp description (reported by Bruno Haible).
5828 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
5830 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
5831 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
5832 Likewise.
5833 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
5834 Likewise.
5836 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
5838 * NEWS: Mention AT_COPYRIGHT.
5840 * tests/local.at (AT_CMP): Use diff directly on input files rather
5841 than copying them.
5843 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
5844 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
5846 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5847 and Paul Eggert <eggert@cs.ucla.edu>
5849 * tests/autotest.at (Empty test suite): New test.
5850 * tests/torture.at (Substitute and define special characters)
5851 (Substitute a 2000-byte string, Define to a 2000-byte string)
5852 (Substitute a newline, Define a newline): New tests.
5854 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5856 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
5857 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
5858 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
5859 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
5860 (Standard regular expressions): New test.
5861 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
5862 excess test name quoting.
5863 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
5864 CPPFLAGS to `configure' instead of setting it in `configure'.
5866 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
5867 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
5868 on some platforms.
5870 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
5871 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
5873 * tests/local.at (AT_CMP): New macro.
5874 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
5875 (AC_SAVE_STATE): Move environment grep...
5876 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
5877 (AT_CONFIG_CMP): New macro.
5878 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
5879 * tests/c.at (Extensions): Do not exit early.
5880 * tests/atlocal.in: Inherit $GREP.
5882 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
5883 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
5885 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
5886 (AC_COPYRIGHT): Factor header comment portion out and move into...
5887 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
5888 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
5889 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
5890 --version output.
5891 * tests/local.at: Add Autoconf test suite copyright notice.
5892 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
5894 2005-02-04 Bruno Haible <bruno@clisp.org>
5895 and Paul Eggert <eggert@cs.ucla.edu>
5897 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
5899 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
5901 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
5902 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

5965 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5966 Update the long comment explaining it.
5968 m4_require no longer writes an ``is required by'' line to the
5969 execution stack. It contains only one bit of non-redundant
5970 information: that the macro was required, not called. And even
5971 this bit is useless in most situations: have you ever met a macro
5972 which both calls and requires the same macro?
5974 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5975 (_m4_defun_pro_outer): ... only via this macro, for the outermost

5983 * tests/m4sugar.at (m4_require): Expect output without the
5984 ``is required by'' messages.
5986 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
5988 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
5989 rather than x for expr.
5991 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
5992 this is safe.
5993 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.

6020 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
6022 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
6023 Warn about newline stripping in `` and $(). Update Solaris
6024 version to 9.

6028 stripping.
6030 2005-01-19 Stepan Kasal <kasal@ucw.cz>

6052 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
6054 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

6078 otherwise.
6079 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
6080 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
6081 stored in _m4_divert_diversion or _m4_divert_dump.
6082 (m4_divert_pop): When the parameter is given, compare the symbolic
6083 name with the last diversion pushed on the stack. Previously, the
6084 current diversion was compared with the numeric value of the
6085 diversion given as the parameter.
6086 (m4_require): If the macro hasn't been expanded yet, call ...
6087 (_m4_require_call): this new macro.

6120 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

6122 not essential. Reported by Magnus Therning.
6123 * tests/torture.at (autoreconf.): New banner.
6124 (autoreconf and non-AC configure): Rename to `Non-Autoconf

6173 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
6174 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

6364 * tests/Makefile.am (installcheck-local): Add check-local dependencies.
6366 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
6368 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
6369 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
6370 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
6371 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
6373 2004-12-07 Stepan Kasal <kasal@ucw.cz>
6375 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous
6376 patch: extra "-l"s.
6378 2004-12-06 Paul Eggert <eggert@cs.ucla.edu>
6380 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Check libc before
6381 looking elsewhere for getmntent. Problem reported by Mark D. Baushke.
6382 * doc/autoconf.texi (Particular Functions): Mention new behavior.
6384 2004-12-03 Stepan Kasal <kasal@ucw.cz>
6386 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
6387 out the common code to ...
6388 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
6389 value of the #define--default to 1, iff the macro was called
6390 with exactly one parameter.
6392 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
6394 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
6395 "char c = '\200';" rather than "char c = 0x80;" as the
6396 latter doesn't conform to the strict C standard due to
6397 overflow on signed char hosts.
6399 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
6400 to -qlanglvl=ansi. We don't want to disable extensions.
6402 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
6404 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
6405 (Using Autotest, testsuite Scripts, Writing testsuite.at):
6406 Reword slightly to avoid some English-language problems noted

6418 along with some nearby cruft.
6419 * doc/autoconf.texi (Libtool): Libtool can be used without
6420 Automake (not without Autoconf).
6421 (Introduction): Mention lists.gnu.org.
6422 * BUGS: Don't mention bugs.gnu.org.
6423 Remove mention of ancient libtool compatibility problem.
6424 * NEWS: Mention that bugs.gnu.org is kaput.
6425 * README: Likewise. Mention where mailing list archives can be found.

6447 in my editing of the previous patch. Problem reported
6448 by Alexandre Duret-Lutz.
6450 2004-11-22 Stepan Kasal <kasal@ucw.cz>
6452 * doc/autoconf.texi (Autoconf Language): Explain that
6453 ``descriptions'' may not be double quotes.
6454 (Quotation Rule Of Thumb): Likewise.
6455 (Pretty Help Strings): Likewise; remove the wrong comment;
6456 simplify the examples and improve their quoting.
6458 2004-11-13 Stepan Kasal <kasal@ucw.cz>
6460 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
6461 the $1_found variable, don't test whether the file is executable;
6462 Both things are checked ...
6463 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
6464 the former ``test -f''.
6465 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
6467 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>
6469 * doc/autoconf.texi (Limitations of Usual Tools): Avoid cp -r;
6470 use cp -R instead.
6472 2004-11-10 Derek R. Price <derek@ximbiot.com>
6474 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
6475 limitations. Reorder paragraphs for clarity.
6477 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
6479 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
6480 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
6481 variants", "Unix", and some related minor wording fixups.
6483 (Shellology, Special Shell Variables): Document that the Zsh
6484 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
6485 to Alexandre Duret-Lutz for this info.

6494 of putenv. Problem reported by Michael Wardle.
6496 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
6498 * doc/autoconf.texi (auindex): New macro.
6499 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
6500 Problem reported by Stepan Kasal.
6502 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
6504 Fix problems reported by Andreas Buening in:
6505 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
6506 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
6507 in test makefile.
6508 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
6509 readable; it's not true in OS/2-emx.
6511 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
6513 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
6514 "/usr/include", clear ac_x_includes instead of leaving it as "no"
6515 (trivial change). Problem and patch reported by Andrew Church in:
6516 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
6518 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
6520 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
6521 three args in examples. Problem reported by Frederik Fouvry in:
6522 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
6523 Also, fix some minor spacing and punctuation bugs.
6525 2004-09-02 Akim Demaille <akim@epita.fr>
6527 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
6528 "case" to restore ordering.
6529 Reported by Stepan Kasal.
6531 2004-08-26 Akim Demaille <akim@epita.fr>
6533 * doc/autoconf.texi: Minor typos and stylos.

6537 * configure.ac (AC_INIT): Bump to 2.59c.
6539 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
6541 Version 2.59b.
6543 * README: Add advice about m4 1.4.2.
6545 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
6546 texinfo.tex for now (done by hand now).
6547 * Makefile.maint (wget_files, cvs_files):
6548 Remove ansi2knr.c; nobody uses it.
6549 (ansi2knr.c-url_prefix): Remove.
6550 (cvs-update): Fix test for failure. I don't know why it ever
6551 worked...
6553 * doc/autoconf.texi: Update URLs, some of which went stale.
6554 Use @uref rather than @href.
6556 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
6557 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
6559 * config/config.guess, config/config.sub, config/elisp-comp,
6560 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
6561 doc/fdl.texi, doc/standards.texi: Sync with master copy.
6563 * NEWS, TODO, configure.ac, bin/autoscan.in,
6564 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
6565 doc/install.texi, lib/Autom4te/Configure_ac.pm,

6569 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
6570 tests/tools.at, tests/torture.at:
6571 Use "file name" rather than "filename" or "path",
6572 to be consistent with the terminology of the GNU coding standards.
6574 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
6576 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
6577 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
6578 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
6579 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
6581 More fixes to support spaces in the name of the build directory.
6582 This isn't a complete fix but it's an improvement.
6584 * bin/autoconf.as (autom4te_options): New var.
6585 Use it instead of appending to AUTOM4TE, so that we can allow
6586 spaces in the build directory's absolute name.
6587 * bin/autoheader.in ($autoconf): Allow spaces in file names.
6588 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
6589 AT_CHECK_NOESCAPE): Likewise.
6590 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
6591 main program): Likewise.
6593 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
6595 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
6596 From Ralf Corsepius in:

6599 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
6601 * doc/autoconf.texi (Function Portability): Document isinf and
6602 and isnan. From a suggestion by Kevin Ryde.
6604 * lib/Autom4te/General.pm (END): Return correct exit status even
6605 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
6607 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
6609 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
6610 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
6611 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
6613 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
6615 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
6616 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
6617 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
6618 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
6619 * lib/autom4te.in (Automake-preselections): Preselect
6620 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
6622 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
6624 * lib/autom4te.in (Automake-preselections): Preselect
6625 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
6626 trace them.
6628 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
6630 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
6631 Tru64.
6632 * doc/autoconf.texi (Shellology): Mention BIN_SH.
6633 Document problem with "`""`" in pdksh POSIX mode.
6635 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
6637 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
6638 with pdksh, too. Problem reported by Patrick Welche via
6639 Gary V. Vaughan.
6640 * doc/autoconf.texi (Shellology): Note that set -o posix is
6641 useful for pkdsh, too.
6643 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
6645 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
6646 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
6647 Don't fail if ENV or BASH_ENV is readonly.
6648 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
6649 etc. are read only. Problem reported by Ludovic Courtes.
6651 2004-06-23 Noah Misch <noah@cs.caltech.edu>
6653 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
6654 zsh, disable GLOB_SUBST to avoid backslash handling problems.
6655 (trivial change)
6657 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
6659 * doc/autoconf.texi (File System Conventions): Warn about
6660 names like "aux". Problem reported by Eric Blake.
6662 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
6663 by zero instead of array size, so that we can use any arithmetic
6664 constant expression (instead of requiring an integer constant
6665 expression). This allows us to test expressions like DBL_MAX <
6666 LDBL_MAX, which didn't conform to the C standard using the old
6667 method.
6668 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
6669 now that we can do floating-point tests at compile time.
6671 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
6673 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
6674 and LDBL_EPSILON, as the resulting expression isn't an
6675 integer constant expression and violates the C standard.
6676 Problem reported by Nelson H. F. Beebe. Also, check
6677 for "L" suffix, and check that long double doesn't have
6678 worse range or precision than double, that mixed-mode
6679 arithmetic doesn't generate a diagnostic, that double
6680 constants fit in long double.
6682 2004-06-03 Kevin Ryde <user42@zip.com.au>
6684 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
6685 malloc(0) and realloc(NULL,size).
6687 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
6688 Bob Proulx.
6690 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
6692 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
6693 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
6694 by Jim Meyering.
6696 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
6698 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
6699 can be rewritten using if-then-else. Suggested by Bruno Haible.
6701 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
6703 * doc/autoconf.texi (testsuite Scripts): Fix typo.
6704 Problem reported by Stepan Kasal.
6706 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
6708 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
6709 change). Patch reported by Ralf Wildenhues in
6710 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
6712 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
6713 function F exists if the compiler and linker let you compile an
6714 expression like (F != 0). Recent versions of GCC optimize away
6715 the reference to F in that case, since every function address must
6716 be nonzero, so the link succeeds even if F does not exist.
6717 Problem reported by Manu in
6718 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
6720 * doc/autoconf.texi (Systemology): Standardize on the spelling of
6721 "Unix". Many uses changed.
6722 (Limitations of Builtins): Explain better why the ! command isn't
6723 portable.
6725 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
6727 * lib/autom4te.in (Automake-preselections): Preselect
6728 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
6730 2004-05-19 Kevin Ryde <user42@zip.com.au>
6732 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
6733 referencing AC_FUNC_STRERROR_R.
6735 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
6736 note pessimistic assumption when cross compiling.
6738 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
6740 * doc/autoconf.texi (Limitations of Make): Note that BSD make
6741 (until 2004) invoked subcommands with sh -e, contra POSIX.
6742 Reported by Kevin Ryde.
6744 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
6746 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
6747 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
6748 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
6749 `test -f " /usr/bin/grep"', which _always_ failed.
6750 (AC_PROG_SED): Ditto bogus PATH fix.
6751 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
6752 requires that grep correctly supports _multiple_ `-e' options, rather
6753 than stating only that grep should accept `-e'.
6755 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
6757 Port to C99, which requires that 'exit' be declared.
6759 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
6760 to ensure that stdlib.h is included.
6761 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
6762 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
6763 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
6764 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
6765 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
6766 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
6767 when using 'exit' in a test; C99 requires that 'exit' be declared.
6769 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
6771 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
6772 now prefers 'grep' implementations that accept -e.
6773 (Limitations of Usual Tools): Describe problems of traditional
6774 egrep and fgrep with long input lines, and of traditional grep
6775 with -e.
6776 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
6777 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
6778 All callers changed. Append /usr/xpg4/bin to the PATH, for
6779 Solaris.
6780 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
6781 the user with complaints about multiple -e options.
6782 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
6783 Define it with AC_PROG_GREP.
6784 * configure.ac (AC_PROG_GREP): Add.
6785 * lib/freeze.mk (GREP): New macro.
6787 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
6789 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
6790 a possible candidate only after all others fail, rather than
6791 consulting it first. This improves backward compatibility by
6792 better reflecting the way shell selection occurred in previous
6793 versions of Autoconf, and should help to avoid triggering latent
6794 problems in other packages, such as the one in Automake where zsh
6795 is not handled robustly:
6796 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
6797 Although it is not Autoconf's responsibility to work around
6798 problems in Automake, it nevertheless makes sense to avoid
6799 introducing unnecessary incompatibilites.
6801 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
6802 Gary V. Vaughan <gary@gnu.org>
6804 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
6805 how deeply nested we are when a suitable tool is found, set the
6806 ac_path_TOOL_found flag.
6807 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
6808 nested we are in this macro. Break out of all 3 nested loops if
6809 ac_path_TOOL_found is set.
6811 2004-04-21 Gary V. Vaughan <gary@gnu.org>
6813 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
6814 of the _AS_PATH_WALK loop too if GNU flavor is found.
6816 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
6818 * doc/autoconf.texi (Limitations of Make): Update documentation
6819 for `$<'. New entry `Long lines', based on a report from Simon
6820 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
6821 paragraph about DJGPP, based on a mail from Richard Dawe.
6823 2004-04-20 Paul Eggert <eggert@twinsun.com>
6825 * tests/c.at (C keywords): Don't assume that GCC supports
6826 "restrict" and "inline", as sufficiently-old GCC versions do not
6827 (also, GCC configured to be in pedantic C89 mode does not).
6828 Problem reported by Sumit Pandya in:
6829 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
6831 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
6832 consider -g to work if it generates warnings when plain compiles
6833 don't. Problem reported by Braden McDaniel in:
6834 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
6836 * doc/autoconf.texi (Slashes): New section, to document a problem

6845 2004-04-20 Gary V. Vaughan <gary@gnu.org>
6847 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
6848 best tool so far counter rely on the tool path variable name to
6849 avoid checks for one tool being affected by the results of running
6850 the length check on a previous tool.
6852 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
6853 match expression argument, as different greps have different
6854 regular expression flavours.
6855 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
6856 literals.
6857 (AC_PROG_EGREP): Pass 'EGREP$'.
6858 (AC_PROG_GREP): Pass 'GREP$'.
6860 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
6862 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
6863 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.

6868 Types, Specific Compiler Characteristics, System Services,
6869 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
6870 etc. consistently instead of 'long', 'short', 'unsigned' etc.
6871 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
6872 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

6883 2004-03-28 Paul Eggert <eggert@twinsun.com>
6885 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
6886 now defines HAVE_DECL_TZNAME if it is declared, when
6887 HAVE_STRUCT_TM_TM_ZONE is not defined.
6888 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
6889 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
6890 for HAVE_TZNAME.
6892 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
6894 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected

6900 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
6901 Fortran compiler is ifort, also added pghpf; thanks to Nelson
6902 H. F. Beebe for the bug report.
6904 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
6906 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
6907 quoted -cmdline argument in Portland Group compiler (bug
6908 reported by Jeffrey J. Barteet).
6910 2004-03-25 Kevin Ryde <user42@zip.com.au>
6912 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
6913 (Run Time): ... here, where it's now mentioned.

6934 AC_CHECK_TOOLS.
6935 (Specifying Names): Document the reason for these future
6936 behavioral changes.

6938 new macros.
6939 * NEWS: Document these changes.
6941 * doc/autoconf.texi: Avoid macros with unbraced arguments,
6942 they make TeX hang up.

6947 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
6948 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
6949 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
6950 vowel.

6958 * bin/Makefile.am (edit): Don't use $< in a context where
6959 POSIX doesn't require support for it. Use $@.in instead.
6960 Problem reported by Anthony N. Frasso in
6961 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
6962 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
6964 2004-02-23 Gary V. Vaughan <gary@gnu.org>
6966 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
6967 from the next generation of Libtool.
6968 * lib/autom4te.in (Autoreconf-preselections): Ditto.
6970 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6972 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
6973 is not always thread-safe. Report from Nathanael Nerode.
6975 2004-02-18 Paul Eggert <eggert@twinsun.com>
6977 Fix a dependencies problem, stemming from a Autoconf 2.59 build
6978 problem on QNX reported by Stephen Rasku in
6979 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
6981 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
6982 $(m4sh_m4f_dependencies); this removes a FIXME.
6983 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
6984 (MAINTAINERCLEANFILES): Split into pieces,
6985 one per related section. Add $(srcdir)/wrapper.in.
6987 2004-02-09 Paul Eggert <eggert@twinsun.com>
6989 * doc/autoconf.texi (Setting Output Variables): Emphasize that
6990 AC_SUBST provides no portable way to escape literal newlines.
6992 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6993 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6994 Darwin uses -lcrt2.o and there's little point to cataloging all
6995 the system variants. Partial fix reported by Andreas Waechter in:
6996 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
6997 for bug reported by Nelson H. F. Beebe in:

7012 the behavior of the third argument.
7013 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
7014 correctly the behavior of the third argument. Document

7020 Eric Sunshine <sunshine@sunshineco.com>
7021 Paul Eggert <eggert@twinsun.com>
7023 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

7025 parameter. Expand _AS_SHELL_FN_SPY.
7026 (AS_INIT_WITH_SHELL_FN): Removed.
7027 (_AS_SHELL_FN_SPY): New macro.
7028 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
7029 macros.
7030 (AS_SHELL_SANITIZE): Remove loop to find better shell
7031 and documentation for the parameter.

7035 (AS_REQUIRE_SHELL_FN): Require shell functions when
7036 it is used.
7037 (_AS_LINENO_WORKS): Put around braces, we do not
7038 trigger the bash bug anymore.
7039 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
7040 use AS_INIT_WITH_SHELL_FN.
7041 * bin/autoconf.in, tests/wrapper.in: Regenerated.
7043 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
7045 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

7049 (AU_DEFUN): Honor the third parameter, create autoupdate
7050 macros with AU_DEFINE.
7051 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
7052 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

7071 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
7072 2003 (except 1997) to the list of copyright years. This undoes
7073 the 2003-05-22 change, which removed the older years from the list.
7074 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
7076 2004-01-27 Gary V. Vaughan <gary@gnu.org>

7087 _AC_PROG_GREP, and AC_PROG_SED.
7088 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
7089 longest input length accepted by a command.
7090 (AC_PROG_SED): Use it.
7091 * doc/autoconf.texi (Particular Programs): Document the changes.
7092 * NEWS: Updated.
7094 2004-01-27 Paul Eggert <eggert@twinsun.com>

7116 sources.
7118 2004-01-26 Paul Eggert <eggert@twinsun.com>
7120 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
7121 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
7122 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
7123 not <inttypes.h>. Problem reported by Tim Mooney in
7124 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
7125 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
7126 Likewise.
7128 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
7129 otherwise "make check" fails because it forbids cmp (I guess
7130 because cmp treats files as binary on DOS-like systems).
7132 * tests/mktests.sh: Update copyright date to 2004, since some tests
7133 have changed in 2004.
7135 2004-01-23 Gary V. Vaughan <gary@gnu.org>

7138 non-truncating sed or gsed program in PATH.
7139 * tests/acprograms.at: Add it.

7141 * NEWS: Updated.
7143 2004-01-15 Paul Eggert <eggert@twinsun.com>
7145 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
7146 -std1 disables some useful extensions on Tru64. Problem reported
7147 by N. Lichtmaier in
7148 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
7150 2004-01-14 Paul Eggert <eggert@twinsun.com>
7152 * doc/autoconf.texi (Programming in M4sh): Document that
7153 AS_MKDIR_P succeeds if the destination is a symbolic link
7154 to an existing directory.
7155 (Limitations of Usual Tools): Note that mkdir -p might not
7156 succeed on symlinks to directories.
7158 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
7160 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
7161 * bin/autoheader.in: Grammar fix in message.
7162 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
7163 Test for dir before calling mkdir -p. (trivial changes)
7165 2004-01-13 Eric Blake <ebb9@byu.net>
7167 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
7168 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
7170 2004-01-10 Jim Meyering <jim@meyering.net>
7172 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
7174 2004-01-09 Paul Eggert <eggert@twinsun.com>
7176 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
7177 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
7178 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
7179 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
7180 AC_COMPILE_IFELSE, since we now assume our caller invokes
7181 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
7182 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
7183 of AC_RUN_IFELSE; this avoids the warning mentioned above.
7184 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
7186 2004-01-07 Paul Eggert <eggert@twinsun.com>
7188 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
7189 `"'...'"`, as it's confusing (and I suspect it may not work on
7190 some platforms). The code was incorrect anyway, as it assumed
7191 that \$ evaluated to itself in that context. Reported by
7192 Alexandre Duret-Lutz.
7194 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
7196 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
7197 and _LT_AC_TAGCONFIG.
7199 2004-01-06 Paul Eggert <eggert@twinsun.com>
7201 * doc/autoconf.texi (One Macro Call): Fix an incorrect
7202 example, and add more examples. Reported by Eric Sunshine.
7204 2004-01-05 Paul Eggert <eggert@twinsun.com>
7206 * doc/autoconf.texi (Limitations of Usual Tools):
7207 Remove warning against "rm -fr" introduced yesterday; it
7208 was a false alarm.
7210 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
7211 autoscan, autoupdate, ifnames): Don't use chmod -w.
7212 * lib/Makefile.am (autom4te.cfg): Likewise.
7213 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
7214 "chmod -w".

7217 Paolo Bonzini <bonzini@gnu.org>
7219 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
7220 by doing lineno substitution only on lines containing "$LINENO".
7222 2004-01-04 Paul Eggert <eggert@twinsun.com>
7224 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
7225 Use "rm -f" to remove conftest.sed, not plain "rm".
7226 Bug reported by David Relson in
7227 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
7229 * Makefile.am (autom4te-update):
7230 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
7231 * Makefile.maint (my-distcheck, do-po-update): Likewise.
7232 * doc/autoconf.texi (Guidelines): Likewise.

7242 Warn against "rm -fr".
7244 2004-01-03 Paul Eggert <eggert@twinsun.com>
7246 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
7247 -c -o might not work. From a suggestion by Kevin Ryde.

7249 of Usual Tools, Limitations of Make, Making testsuite Scripts):
7250 Don't put '-o' after non-options, as POSIX doesn't allow this.
7251 Mention that cc's name might be gcc or c89 or whatever.

7318 * config/announce-gen (&print_locations, &print_signatures)
7319 (&sizes): New.
7320 Use them.
7321 No longer rely on Gnus to inline the list of signatures: compute
7322 them on the fly.
7324 2003-11-24 Akim Demaille <akim@epita.fr>
7326 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can
7327 override some files.
7328 (Input): AC_CONFIG_AUX_DIR(aux) is a bad idea on DOS.
7329 From Debian Autoconf 2.58.
7331 2003-11-24 Akim Demaille <akim@epita.fr>

7369 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
7370 than $target since the latter is not usual, add guidelines on when to

7375 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

7395 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

7530 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
7531 cross test.
7533 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
7535 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
7536 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

7541 --help output.

7548 Problems reported by Eric Sunshine.
7550 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
7552 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
7553 -mGLOB_options_string stuff for Intel ifc, which can cause
7554 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

7557 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
7559 * doc/autoconf.texi: Document new FC Fortran macros.

7573 -lcrt[01].o.
7575 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
7577 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
7578 cache variable instead of $G77 to decide whether to include -O2,
7579 since $G77 is specific to Fortran 77.
7581 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7583 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
7584 free" flag. Re-order flags tested into rough order of popularity.
7586 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7588 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
7589 arguments so that it can be used with syntax identical to
7590 AC_PROG_F77, and so that we can more easily decide to
7591 remove/deprecate the DIALECT optional argument in the future if it
7592 proves troublesome.
7593 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
7594 non-freeform-supporting compilers. Document freeform flags.
7596 2003-10-03 Akim Demaille <akim@epita.fr>
7598 * configure.ac: Look for emacs, not macs.
7599 Reported by Eric Sunshine.
7601 2003-10-03 Akim Demaille <akim@epita.fr>
7603 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
7604 * bin/autoreconf.in (autoreconf_current_directory): Create the

7606 Suggested by Alexandre Duret-Lutz.
7608 2003-10-03 Akim Demaille <akim@epita.fr>
7610 * configure.ac: Quotation and formatting changes.

7632 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
7633 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
7635 2003-09-30 Akim Demaille <akim@epita.fr>
7637 * config/announce-gen (&print_news_deltas): Extracted from...
7638 (&print_changelog_deltas): here.

7640 (@news_file): this.
7642 2003-09-30 Nicolas Joly <njoly@pasteur.fr>

7645 have been created when invoking the compiler.

7657 Problem reported by Lars J. Aas in
7658 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
7659 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
7660 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
7661 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
7663 2003-09-26 Akim Demaille <akim@epita.fr>
7665 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
7666 directory for AC_CONFIG_COMMANDS' first argument exists.
7667 This makes valid the invocation of _AC_SRCPATH that follows.
7668 Reported by Eric Sunshine.
7669 * doc/autoconf.texi (Configuration Commands): Adjust.
7671 2003-09-26 Akim Demaille <akim@epita.fr>
7673 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
7674 Reported by Ralf Corsepius.
7676 2003-09-26 Akim Demaille <akim@epita.fr>
7678 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
7679 arguments.
7680 Actually, use AU_ALIAS.
7681 From Bruno Haible.

7690 2003-09-26 Akim Demaille <akim@epita.fr>
7692 The test suite are sometimes assigning timings incorrectly.
7693 Reported by Henk Krus.
7694 Diagnosed by Nicolas Joly.
7696 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
7697 AT_help_all.
7698 Instead of making AT_help a sequence of assignments to grow
7699 $at_help_all, just make AT_help_all be the growing contents of
7700 $at_help_all, and make a single assignment in...
7701 (AT_INIT): here.
7702 (at_times_skip): Flip the meaning and rename as...
7703 (at_times_p): this.
7704 (AT_INIT): When summarizing the test that ran, remove
7705 $at_times_file after use, and check it is present before trying to
7706 use it.
7708 2003-09-25 Akim Demaille <akim@epita.fr>
7710 Version 2.57d.
7712 * bin/Makefile.am (edit): Handle '@configure_input@'.
7713 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
7714 (ifnames): chmod -w.
7715 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
7716 executables, not bin/ executables! Otherwise all the magic needed
7717 to find non installed files is turned off. This caused a failure
7718 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
7719 as found in its environment (sent by tests/autoreconf): pointing
7720 to bin/autom4te that could not find its files.
7721 * tests/mktests.sh: Force the replacement of generated files, for
7722 the sake of "mv" program that are interactive when overwriting a
7723 -w file.
7724 * config/install-sh: Upgrade from CVS Automake.
7726 2003-09-23 Paul Eggert <eggert@twinsun.com>

7731 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
7732 Paul Eggert <eggert@twinsun.com>
7734 Trivial change to support GCC's configuration procedure.
7735 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
7736 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
7737 about inconsistency if the preprocessor is set to give errors for
7738 any warning.

7863 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
7864 are defaulted by AT_CHECK anyway.

7951 2003-08-21 Akim Demaille <akim@epita.fr>
7953 First stab at preserving warnings between calls to autom4te,
7954 including when the cache is used.
7956 There are still several issues: (i) there are too many runs of m4
7957 (one for include, one for warnings, and some more), (ii) warnings
7958 spreading on several lines are not handled gracefully, (iii) the
7959 code meant to have the call stack display for errors does not work
7960 (its handling should move from m4 to autom4te).
7962 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7963 Use them.
7964 (@preselect): Add m4_warn.
7965 ($exit_status): Remove, use $exit_code.
7966 ($help): Use Autom4te::ChannelDefs::usage.
7967 (&handle_m4): No longer define the m4_warnings.
7968 At each run, extract and report the warnings.
7969 Always cache the result, including if the exit status is on
7970 failure, since if nothing changes, we should result in the same
7971 failure, hence we can use the cache.
7972 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7973 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7974 Remove.
7975 (m4_warn): Redefine as a do-nothing: it is its invocation that
7976 matters, as warnings are now reported via traces.
7977 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7978 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7979 the latter reveals calls to the former.
7981 Adjust the tests.
7983 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
7985 2003-08-21 Akim Demaille <akim@epita.fr>
7987 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
7988 Use them.
7990 2003-08-21 Akim Demaille <akim@epita.fr>
7992 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
7993 forward order.
7994 * lib/Autom4te/ChannelDefs.pm: Doc typos.
7995 (&parse_warnings): Accept a list of warning requests.
7996 (&usage): Return a string, not a side effect.
7997 (cross): New warning category.
7999 2003-08-21 Akim Demaille <akim@epita.fr>
8001 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
8002 (&require_configure_ac): Accept an optional directory argument.
8003 ($configure_ac): Remove.
8004 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
8005 (&catfile): Remove.
8006 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
8007 * bin/autoscan.in: Adjust.
8009 2003-08-20 Akim Demaille <akim@epita.fr>
8011 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
8012 Reported by Alexandre Duret-Lutz.
8014 2003-08-20 Akim Demaille <akim@epita.fr>
8016 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
8017 * bin/autom4te: Adjust.
8018 In particular, be Autoconf tools are really silent when properly
8019 working, bind the verbosity of the 'note' channel to $verbose.
8020 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
8021 (&xsystem, &contents): Remove, since they are exported by...
8022 * lib/Autom4te/FileUtils.pm: this.
8023 More perldoc.
8024 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
8025 * lib/Autom4te/FileUtils.pm: here.
8027 2003-08-20 Akim Demaille <akim@epita.fr>
8029 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
8030 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

8057 and m4_sinclude.
8059 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>

8082 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
8083 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
8084 shorter column three. Add DESCRIPTION to log file content.
8086 2003-08-13 Derek Price <derek@ximbiot.com>
8088 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

8100 (AT_CHECK_NOESCAPE): ...to this new macro.
8102 2003-07-31 Paul Eggert <eggert@twinsun.com>
8104 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
8105 in Bash 2.01. Problem reported by Brian Gough in
8106 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.

8116 inside '#ifndef __cplusplus'. Problem reported by
8117 Bob Friesenhahn.
8119 2003-07-06 Bill Clarke <llib@computer.org>
8121 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
8122 'long', not 'int', for benefit of Sun's recent C++ compilers
8123 (trivial change). See:
8124 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
8125 (This really should be 'intptr_t', not 'long', but that would
8126 take more work.)
8128 2003-06-25 Akim Demaille <akim@epita.fr>
8130 * lib/Makefile.am (autom4te.cfg): Make it read only.
8131 Depend on Makefile since it contains substitutions.

8140 From Gareth McCaughan.
8142 2003-06-23 Akim Demaille <akim@epita.fr>
8144 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
8145 not all of them. This fixes 1. the fact that when testing
8146 Autoconf there are many many config.log, 2. the incorrect use of
8147 top_srcdir to find config.log.
8148 Don't mix the detailed output of failed test with the summary of
8149 failures. Rather, append detailed log afterwards.
8151 2003-06-23 Akim Demaille <akim@epita.fr>
8153 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
8154 always run: output config.log on $at_group_log.

8223 2003-05-28 Paul Eggert <eggert@twinsun.com>
8225 * NEWS, doc/autoconf.texi (Particular Functions),
8226 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
8227 is the inverse of localtime.
8229 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
8231 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
8232 (handle_exec_errors): New function. Work around $! being
8233 altered by WEXITSTATUS.
8234 (xqx, xsystem): Use handle_exec_errors.
8236 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
8238 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
8239 Do not call `_exit()', simply modify `$?'.
8240 (xsystem): Reset $! before running system, and check it afterward.
8241 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
8242 63 for version mismatches.
8244 2003-05-23 Akim Demaille <akim@epita.fr>
8246 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
8247 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
8248 the middle of a line).
8249 * lib/m4sugar/m4sugar.m4: Likewise.
8250 Remove useless spaces in comments.
8252 2003-05-23 Akim Demaille <akim@epita.fr>
8254 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
8255 exit 63, so that we (or Automake's "missing") can tell the
8256 difference with a plain failure.
8257 * doc/autoconf.texi (Notices): Adjust.
8259 2003-05-23 Akim Demaille <akim@epita.fr>
8261 * Makefile.am, bin/Makefile.am, config/Makefile.am,
8262 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
8263 White spaces cleanup.
8265 2003-05-22 Jim Meyering <jim@meyering.net>
8266 Paul Eggert <eggert@twinsun.com>
8268 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
8269 Remove `#include <stdlib.h>' from the list; we should never
8270 make confdefs.h include <stdlib.h> or <cstdlib>, because the
8271 resulting namespace pollution would cause other tests to fail.
8272 Configure scripts run with some older versions of g++ and HP's
8273 aCC would fail due to such an #include. Problems reported by
8274 Matthew Mueller in <http://bugs.debian.org/120704> and by
8275 Keith Bostic in
8276 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
8277 In the test, use the test declaration before including <stdlib.h>,
8278 as that's closer to how it'll be used.
8280 2003-05-23 Akim Demaille <akim@epita.fr>
8282 * doc/autoconf.texi (Header Portability): ucred.h.
8283 From Ian Redfern.
8285 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8287 Overhaul Autotest's logging: generate separate log files
8288 in testsuite.dir/NNN/testsuite.log, and append them to
8289 testsuite.log instead of re-running the test verbosely.
8291 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
8292 file descriptor, write 0 to at_status_file instead of setting
8293 at_status=0, initialize some new variables (at_status_file,
8294 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
8295 to rerun the tests, instead append the at_group_log to the
8296 at_suite_log when a test fails.
8297 (AT_SETUP): pipe the test case's output into at_tee_pipe,
8298 with the AS_MESSAGE_LOG_FD redirected to stdout.
8299 (AT_CLEANUP): save the output status in $at_status_file
8300 and restore it, redirect the AS_MESSAGE_LOG_FD back to
8301 its original place.
8302 (AT_CHECK): since tests are run with a redirected stdout,
8303 and used to be re-run in verbose mode, turn some $at_verbose
8304 into echo, and don't redirect the output of testing stdout
8305 and stderr.
8307 * lib/autotest/autoconf.texi (testsuite Scripts): Update
8308 the name of the debugging directory and information about
8309 its contents.
8311 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8313 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
8314 parameter.

8384 Reported by Sander Niemeijer.
8385 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.

8387 AC_INCLUDES_DEFAULT.
8389 2003-05-17 Akim Demaille <akim@epita.fr>

8426 and truncate.
8428 2003-05-06 Akim Demaille <akim@epita.fr>
8430 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
8431 longer updates aclocal.m4 if useless, (ii) if a file m4_included
8432 by aclocal.m4 is changed it might require the importing of another
8433 m4 extension file, i.e., aclocal must be run.
8435 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
8436 (&parse_args): Use --force with aclocal if required and supported.
8437 (&autoreconf_current_directory): Use &run_aclocal.

8444 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
8445 argument instead of a file name, so that the request file remains
8446 open during the whole autom4te run.
8447 ($icache_file): New.
8448 (&freeze): Lock the $icache_file.
8450 2003-04-29 Derek Price <derek@ximbiot.com>
8452 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
8453 seperator with m4_append_uniq(). It doesn't work.
8454 (AT_CLEANUP): Add `;' to end of at_help_all.
8455 (AT_INIT): Allow --keywords to be specified more than once. When
8456 grepping $at_help_all for keywords, use the field and keyword
8457 seperators to ensure a complete keyword match. Alter at_prev handling
8458 to support the new --keywords behavior.
8460 2003-04-27 Karl Berry <karl@freefriends.org>
8462 * doc/autoconf.texi: Make the dir entries in the autoconf manual
8463 align better with others. I also made some of the individual
8464 entries on one line, for brevity and to make it easier for me to
8465 sort my dir-example file in the Texinfo distribution :).
8467 2003-04-12 Jim Meyering <jim@meyering.net>
8469 * NEWS: Mention the new macro.

8508 (TEXI2DVI): Make it --batch.
8510 2003-03-31 Derek Price <derek@ximbiot.com>
8512 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
8513 which removed the main loop.
8514 Thanks to Akim Demaille.
8516 2003-03-29 Akim Demaille <akim@epita.fr>

8519 that starts a GUI.
8520 From Ilya Zakharevich.
8522 2003-03-29 Akim Demaille <akim@epita.fr>

8526 Suggested by Paul Eggert.
8528 2003-03-28 Akim Demaille <akim@epita.fr>
8530 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
8531 reading the section "Present But Cannot Be Compiled" when the
8532 header causes problems.
8534 2003-03-28 Akim Demaille <akim@epita.fr>
8536 * tests/torture.at (Configuring subdirectories): Require aclocal
8537 1.4, otherwise the test fails, as it does support configure.ac.
8538 This fixes the "test 40 failed" bug reports.
8540 2003-03-28 Akim Demaille <akim@epita.fr>
8542 * doc/autoconf.texi (C Compiler): `#line' portability.

8609 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
8610 Tru64 make in the "target lookup" section.
8611 (Automake): Automake 1.5+ no longer requires special tools to be
8612 present on the developer's host.

8630 ${ac_make}.
8632 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
8633 When constructing paths with IFS=:, quote the path. If we're

8653 to fix a mismatch between example and discussion.
8655 2003-02-24 Kevin Ryde <user42@zip.com.au>
8657 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
8658 format starting with "-".
8660 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
8662 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
8663 is not portable inside Makefile.
8665 2003-02-20 Akim Demaille <akim@epita.fr>
8667 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
8668 compiler says yeah, but preproc says nope, compiler is right.
8669 Conversely, prompt the reader to send a bug report to the
8670 maintainers of the package, not of Autoconf.
8672 2003-02-20 Klee Dienes <kdienes@apple.com>
8674 * bin/autoreconf.in (autoreconf_current_directory): Properly

8685 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
8686 innocuous variant befor including <limits.h> or <assert.h>. This
8687 works around a bug reported by Albert Chin: HP-UX 11i
8688 (and earlier versions) have a <limits.h> that declares
8689 gettimeofday and many other functions.
8691 2002-12-03 Paul Eggert <eggert@twinsun.com>
8693 Version 2.57.
8695 * NEWS, configure.ac: Update version.

8699 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
8700 nontrivially in main's body, so that f's external declaration is
8701 not optimized away in AIX. This should fix the bug reported by
8702 Martin Frydl in
8703 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
8705 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
8706 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
8707 defined, to support freestanding compilers. This should fix the
8708 bug reported by Momchil Velkov in
8709 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
8711 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
8712 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

8725 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
8727 2002-11-15 Akim Demaille <akim@epita.fr>

8743 Update from masters.
8745 2002-11-14 Akim Demaille <akim@epita.fr>
8747 * Makefile.maint: Sync with Bison, i.e.:
8748 (po-check): Scan .l and .y files instead of the
8749 .c and the .h files that they generate. This fixes the bug
8750 reported by Tim Van Holder in:
8751 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
8752 Look for N_ as well as for _. Try to avoid matching #define for
8753 N_ and _.
8754 From Paul Eggert.
8756 2002-11-14 Akim Demaille <akim@epita.fr>
8758 * doc/autoconf.texi (C Compiler): Compiling several files at once.
8759 From Paul Eggert and Albert Chin-A-Young.

8766 2002-11-14 Kevin Ryde <user42@zip.com.au>
8768 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
8769 than assigning in main, to avoid HP cc +O3 optimizing it away.
8771 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
8773 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
8774 option. Process --recheck after parsing all options. Pass -q
8775 option to configure on --recheck.
8776 (AC_OUTPUT): Pass -q from configure to config.status.
8777 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
8778 arguments to record.
8779 * doc/autoconf.texi (config.status Invocation): Document
8780 config.status -q option.
8782 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

8785 Makefile.in if Makefile.am exists.

8807 Reported by Ezra Peisach.
8809 2002-11-05 Akim Demaille <akim@epita.fr>
8811 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
8812 Remove.
8813 We _have_ to stop using the old compatibility scheme that tried to
8814 avoid useless backslashes because Libtool 1.4.3 contains a
8815 AC_DEFINE([error_t], [int],
8816 [Define to a type to use for \`error_t' if it is not
8817 otherwise available.])
8818 We _have_ to quote the single quote and backslashes with \. The
8819 old compatibility scheme saw that ` was backslashed, and therefore
8820 did not quote the single quote. Hence before this patch, Autoconf
8821 was not compatible with Libtool.
8823 2002-11-04 Paul Eggert <eggert@twinsun.com>
8825 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

8842 (&autoreconf): here.
8843 ($help, $make, &parse_args, &autoreconf_current_directory):
8844 Support -m/--make.
8845 * doc/autoconf.texi (autoreconf Invocation): Adjust.

8863 2002-10-31 Akim Demaille <akim@epita.fr>
8865 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
8866 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
8867 Make variable, not a shell variable.
8868 Suggested by Bruno Haible.
8870 2002-10-31 Akim Demaille <akim@epita.fr>
8872 * bin/autom4te.in (load_configuration): Reject #args out of any
8873 language.
8875 2002-10-31 Akim Demaille <akim@epita.fr>

8889 Suggested by Tim van Holder.
8891 2002-10-29 Paul Eggert <eggert@twinsun.com>
8893 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
8894 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
8895 Problem reported by Bruno Haible.
8897 2002-10-29 Akim Demaille <akim@epita.fr>
8899 * doc/autoconf.texi (Header Templates): Put also in words what the
8900 pictures says to assist free style readers.
8901 (Customizing autom4te): s/--cache=/--cache /.
8903 2002-10-29 Akim Demaille <akim@epita.fr>
8905 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and

9205 * Makefile.maint (wget_files): Remove ansi2knr.c.
9206 (ansi2knr.c-url_prefix): Remove.
9208 2002-10-16 Akim Demaille <akim@epita.fr>
9210 Because of caching, some files that no longer exist and are no
9211 longer required can still cause errors.
9212 Reported by Alexandre Duret-Lutz.
9214 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
9215 to frozen files in @ARGV, as @ARGV must remain being a list of
9216 files. Rather, at M4 call sites, use this...
9217 (&files_to_options): New function.
9218 (&freeze): Use &error.
9219 (&up_to_date): If a file that was included according to the cache
9220 is no longer there, then the output is out dated.
9221 (&main): Don't even check whether a file is up to date is anyway
9222 --force is given.
9223 * tests/tools.at (autom4te cache): New.
9225 2002-10-16 Akim Demaille <akim@epita.fr>
9227 * bin/autoconf.as: Kill dead options.
9228 * bin/autoupdate.in (&parse_args): Kill old options.
9229 * bin/autoreconf.in (&parse_args): Remove dead options.
9230 Factor some code.
9231 (&autoreconf): Report the directories we enter *and leave*, so
9232 that error messages can be easily located, and use GNU Make
9233 format, so that Emacs' compile mode understands us.
9234 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
9235 if some file was changed instead of `print'.
9236 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
9237 (&parse_args): Remove the dead options.
9238 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
9239 autoheader's quiet mode.
9240 (AT_CHECK_AUTOUPDATE): Likewise.
9241 * tests/tools.at (autoupdate): Adjust.
9242 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
9244 2002-10-11 Akim Demaille <akim@epita.fr>
9246 No longer use CPP to check for the existing of headers: use CC to
9247 check for compilability.
9249 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
9250 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
9251 (_AC_CHECK_HEADER_NEW): Rename as...
9252 (AC_CHECK_HEADER): this.
9254 * lib/autotest/general.m4 (AT_INIT): Include the failed test
9255 numbers in the Subject suggestion.
9257 2002-10-11 Akim Demaille <akim@epita.fr>
9259 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
9260 Suggest using AC_CHECK_DECLS instead.
9262 2002-10-11 Akim Demaille <akim@epita.fr>
9264 * tests/torture.at (AC_ARG_VAR): Have configure report the value
9265 of `precious'.
9267 2002-10-11 Akim Demaille <akim@epita.fr>
9269 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
9270 file name to enable parallel executions.
9271 From Sam Varshavchik.
9273 2002-10-08 Akim Demaille <akim@epita.fr>
9275 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
9276 aclocal invocation, as Gettext macros might not be visible to
9277 aclocal.
9278 Instead of blindly running autopoint, scan configure.ac (not the
9279 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
9280 Reported by Paul D. Smith.
9282 2002-10-08 Paul Eggert <eggert@twinsun.com>
9284 Work around problems found when POSIXLY_CORRECT=1 is set.
9285 None of this seems to have anything to do with POSIX, really,
9286 but it's how Perl getopt works.
9287 * bin/autom4te.in (parse_args): Configure GetOpt with
9288 "permute", too.
9289 * doc/autoconf.texi (Invoking autom4te):
9290 --warning -> --warnings.
9291 * lib/autom4te.in: --warning -> --warnings.
9293 2002-09-28 Akim Demaille <akim@epita.fr>
9295 * doc/autoconf.texi (autom4te.cache): New section.
9297 2002-09-28 Akim Demaille <akim@epita.fr>
9299 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
9300 (Automake-preselections): Update.
9301 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
9303 2002-09-28 Akim Demaille <akim@epita.fr>
9305 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
9306 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
9307 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9308 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
9310 2002-09-28 Akim Demaille <akim@epita.fr>
9312 * tests/torture.at (Configuring subdirectories): Be robust to
9313 users who use config.site to require for a cache: in this case,
9314 the two last configure runs, using two different sets of
9315 arguments, trigger a legitimate error.
9317 2002-09-28 Akim Demaille <akim@epita.fr>
9319 * tests/m4sh.at (Functions Support, Functions and return Support):
9320 New.
9322 2002-09-28 Akim Demaille <akim@epita.fr>
9324 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
9325 autoheader are Perl programs.
9326 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
9327 (autom4te): Specify that the sources are in the $srcdir.
9328 * doc/autoconf.texi (Installation Directory Variables): Adjust.
9330 2002-09-28 Akim Demaille <akim@epita.fr>
9332 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
9333 (tm_zone): Move their rules to...
9334 * lib/autoconf/types.m4: here, using AN_ macros.
9335 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
9336 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
9337 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
9338 * lib/autoconf/programs.m4: here.
9339 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
9340 (ETAGS_FOR_AUTOCONF): New.
9341 Use it.
9343 2002-09-28 Akim Demaille <akim@epita.fr>
9345 * lib/autoconf/autoscan.m4: New file.
9346 * lib/autoconf/autoconf.m4: Include it.
9347 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
9348 that were listed in the original autoscan.list.
9349 * lib/autoconf/headers.m4: Similarly with headers.
9350 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
9351 (.m4.m4f): Don't pass --prepend-include, since that's done by
9352 tests/autom4te itself.
9353 * lib/autoscan/Makefile.am: Include freeze.mk.
9354 (autoscan.list): New target --this file is no longer a source.
9355 (autoscan.pre): New file.
9357 2002-09-28 Akim Demaille <akim@epita.fr>
9359 * bin/autoscan.in (@kinds): Make them singular.
9360 Adjust all uses.
9361 (&init_tables): When --debug, report the list of rules to ease
9362 tracking changes in autoscan.list.
9363 * lib/autoscan/autoscan.list (function): Strip comments, sort.
9365 2002-09-28 Akim Demaille <akim@epita.fr>
9367 * lib/autoscan/functions, lib/autoscan/headers,
9368 * lib/autoscan/identifiers, lib/autoscan/makevars,
9369 * lib/autoscan/programs: Merge into...
9370 * lib/autoscan/autoscan.list: this.
9371 * bin/autoscan.in (&init_tables): Adjust.
9373 2002-09-28 Akim Demaille <akim@epita.fr>
9375 * lib/autoscan/functions, lib/autoscan/headers,
9376 * lib/autoscan/identifiers, lib/autoscan/makevars,
9377 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
9378 `functions' line is now prefixed with `function:'.
9379 * bin/autoscan.in (&init_tables): Adjust.
9381 2002-09-28 Akim Demaille <akim@epita.fr>
9383 From now on, autoscan files must always map a macro name to a
9384 word: there is no `default' macro for autoscan.
9386 * bin/autoscan.in (&init_tables): Reject entries with no macro at
9387 all.
9388 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
9389 explicit.
9391 2002-09-28 Akim Demaille <akim@epita.fr>
9393 * bin/autoscan.in (%c_keywords): Remove.
9394 (&used): Keep only track of the words we might be interested in.
9395 (&output_kind): It is no longer needed to look for non active
9396 checks.
9398 2002-09-27 Akim Demaille <akim@epita.fr>
9400 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
9401 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
9402 * lib/autoscan/functions: Adjust.
9403 * doc/autoconf.texi (Particular Functions): Adjust.
9405 2002-09-27 Akim Demaille <akim@epita.fr>
9407 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
9408 from /tmp.
9409 Thanks to Bill Moseley and Paul Eggert.
9410 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
9411 the tmpdir must be created.
9412 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
9413 dir be in the build tree, instead of $TMPDIR.
9415 2002-09-27 Akim Demaille <akim@epita.fr>
9417 * bin/autoscan.in: Improve the comments.
9418 (&parse_args): Drop obsolete undocumented options.
9419 (&output_kind): Output warnings.
9420 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
9421 (getwd): Trigger a warning.
9423 2002-09-26 Akim Demaille <akim@epita.fr>
9425 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
9426 Reported by Ralf Corsepius.
9427 * doc/autoconf.texi (autoreconf Invocation): Likewise.
9429 2002-09-26 Akim Demaille <akim@epita.fr>
9431 Single suffix rules and seperated dependencies are not portable.
9433 * doc/autoconf.texi (Installation Directory Variables): Update.
9434 (Limitations of Make): Some about `Single Suffix Rules and
9435 Separated Dependencies'.
9436 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9437 (ifnames, autoscan, autom4te): Un-factor into several rules.
9439 2002-09-25 Paul Eggert <eggert@twinsun.com>
9441 * BUGS (Interoperability bugs): New section. Mention libtool
9442 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
9444 2002-09-24 Paul Eggert <eggert@twinsun.com>
9446 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
9447 make handles suffix-rules differently from GNU make.
9449 * bin/Makefile.am (SUFFIXES, .in): Remove.
9450 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
9451 Move the body of the old .in rule here.
9453 2002-09-16 Akim Demaille <akim@epita.fr>
9455 i960 compilers create `b.out' files by default.
9456 Reported by Ralf Corsepius.
9458 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
9459 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
9461 2002-09-13 Paul Eggert <eggert@twinsun.com>
9463 * doc/autoconf.texi (Particular Headers): Remove obsolete
9464 reference to `struct timezone' in the description of
9465 AC_HEADER_TIME.
9467 2002-09-13 Akim Demaille <akim@epita.fr>
9469 Version 2.54.
9471 * config/config.sub, config/config.guess: Update.
9472 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
9473 * Makefile.am: Adjust.
9475 2002-09-13 Akim Demaille <akim@epita.fr>
9477 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
9478 reading config.log when the compiler is rejected.
9479 Suggested by Guido Draheim.
9481 2002-09-13 Akim Demaille <akim@epita.fr>
9483 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
9484 (chdir_init) might hang when stat'ing mounted directories.
9485 Reported by Vance Shipley.
9487 2002-09-12 Akim Demaille <akim@epita.fr>
9489 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
9490 the lists.
9492 2002-09-12 Akim Demaille <akim@epita.fr>
9494 * doc/autoconf.texi (Defining Symbols): Present two different
9495 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
9496 difference between 1 argument calls, and 2-3 argument calls.
9498 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
9500 * doc/autoconf.texi: Review grammar and punctuation.
9502 2002-09-11 Paul Eggert <eggert@twinsun.com>
9504 * doc/autoconf.texi: Fix minor formatting, spelling, and
9505 grammatical typos.
9506 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
9507 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
9508 is obsolescent.
9510 2002-09-11 Akim Demaille <akim@epita.fr>
9512 * doc/autoconf.texi (Questions): Rename as...
9513 (FAQ): this.
9514 (Defining Directories): New.
9516 2002-09-09 Akim Demaille <akim@epita.fr>
9518 * doc/autoconf.texi (Making testsuite Scripts): Update.
9519 Suggested by Nishio Futoshi.
9521 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
9523 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
9524 plain `@' is wanted.
9526 2002-09-09 Akim Demaille <akim@epita.fr>
9528 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
9529 `duplicates', since the algorithm was too naive and could keep
9530 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
9531 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
9532 Reported by Ralf Corsepius.
9533 * tests/torture.at (Configuring subdirectories): Exercise these
9534 cases.
9536 2002-09-09 Akim Demaille <akim@epita.fr>
9538 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
9539 looking for a replacement file.
9540 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
9541 directory is relative.
9542 * doc/autoconf.texi (Generic Functions): Clarify the replacement
9543 directory definition.
9544 Reported by Andreas Schwab and Jim Meyering.
9546 2002-09-06 Akim Demaille <akim@epita.fr>
9548 * doc/autoconf.texi (Setting Output Variables): Clarify what
9549 precious variables are.
9550 Suggested by Pontus Skoeld.
9552 2002-09-05 Akim Demaille <akim@epita.fr>
9554 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9555 (ifnames, autoscan, autom4te): Since we don't only depend on
9556 configure.ac variables (such as VERSION etc.), but also on prefix
9557 and so forth, depend on Makefile, not configure.ac.
9558 Reported by Alexandre Duret-Lutz.
9559 * doc/autoconf.texi (Installation Directory Variables): Adjust.
9561 2002-09-05 Kevin Ryde <user42@zip.com.au>
9563 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
9564 doesn't seem to be confined to ia64, just say "some versions".
9566 2002-09-04 Akim Demaille <akim@epita.fr>
9568 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
9569 Automake 1.6c.
9570 * Makefile.am (maintainer-clean-local): Remove.
9571 (MAINTAINERCLEANFILES): Remove COPYING.
9573 2002-09-03 Paul Eggert <eggert@twinsun.com>
9575 * doc/autoconf.texi (Configuration Commands): Remove obsolete
9576 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
9577 Brinkmann.
9579 2002-09-03 Akim Demaille <akim@epita.fr>
9581 * configure.ac: Bump to 2.53d.
9582 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
9583 as of today, on Automake's team suggestion.
9585 2002-09-03 Akim Demaille <akim@epita.fr>
9587 Version 2.53c.
9589 2002-09-02 Akim Demaille <akim@epita.fr>
9591 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
9592 SITE_MACRO_DIR.
9593 * configure.ac: Disable SITE_MACRO_DIR.
9595 2002-09-02 Jim Meyering <meyering@lucent.com>
9597 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
9598 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
9599 Also, tweak grammar: s/make sure to/be sure to/.
9601 2002-09-02 Paul Eggert <eggert@twinsun.com>
9603 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
9604 directory names are generally preferable to physical names.
9606 2002-09-02 Akim Demaille <akim@epita.fr>
9608 * lib/Autom4te/General.pm (&update_file): s/die/error/.
9609 Reported by Raja R. Harinath.
9610 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
9611 * bin/autoupdate.in: Use error instead of die.
9613 2002-09-01 Paul Eggert <eggert@twinsun.com>
9615 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
9616 ordinary shell concatenation rather than echo+tr+sed command that
9617 runs afoul of a long-line-related sed bug in Solaris 8.
9619 * bin/autoheader.in (parse_args): --warning -> --warnings.
9621 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
9622 stdout, as traditional "ls" does.
9623 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
9624 _AC_COMPILER_EXEEXT_O): Likewise.
9625 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
9627 * bin/autoconf.as: Add --prepend-include option. This patch was
9628 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
9629 but bin/autoconf.in is generated automatically from bin/autoconf.as.
9631 * bin/autoconf.in, configure: Regenerate.
9633 * doc/autoconf.texi (Special Shell Variables): Mention
9634 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
9636 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
9637 MAILPATH and set PS1, PS2, PS4 to default values, to work
9638 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
9639 For LC_ALL etc, first try to set to "C" as POSIX requires and as
9640 the Autoconf documentation specifies; fall back to "unset" only if
9641 this fails. Use a shell for-loop for this rather than an m4 loop,
9642 to shorten the output script.
9644 2002-08-30 Paul Eggert <eggert@twinsun.com>
9646 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
9647 1003.1-2001's requirements for CDPATH. Give a simpler workaround
9648 for the CDPATH problem. Document PWD.
9649 (Limitations of Builtins): Document the problem that "cd $foo" and
9650 "ls $foo" may refer to different directories in shells conforming
9651 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
9652 example, since the old example is now out of date.
9654 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
9655 FOO" and "ls FOO" talk about different directories; this catches
9656 problems when POSIX 1003.1-2001 "cd" fails due to symlink
9657 spaghetti.
9659 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
9660 of rolling our own unset.
9661 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
9662 in practice we needn't worry about CDPATH if unset doesn't work.
9664 * Makefile.in, aclocal.m4, bin/Makefile.in,
9665 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
9666 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
9667 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
9668 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
9669 tests/Makefile.in: Regenerate with Automake 1.6.3.
9671 * config/config.guess, config/config.sub, config/mkinstalldirs:
9672 Update.
9674 * configure: Regenerate with self.
9676 2002-08-30 Kevin Ryde <user42@zip.com.au>
9678 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
9679 default output.
9681 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
9683 * bin/autom4te.in (Request::load): Correctly test for "do" read
9684 failure.
9686 2002-08-29 Akim Demaille <akim@epita.fr>
9688 * lib/Autom4te/General.pm (&xqx): New.
9689 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
9690 hand, which is not portable.
9691 (&error): New.
9692 * bin/autom4te.in: Use them.
9693 Use &error instead of die.
9694 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
9695 Adjust.

9699 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
9700 default list of compilers to try, since it was long ago superseded
9701 by the ksh fc builtin. Suggested by Steven G. Johnson.
9703 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
9705 * doc/autoconf.texi (Invoking autom4te): End the option table,
9706 fixing a bug introduced by the previous patch.
9707 (Limitations of Make): Add a 'target lookup' subentry in the

9722 * doc/install.texi: Include copyright symbol in copyright notice.
9724 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
9725 Replace with:
9726 (AM_MAKEINFOFLAGS): New macro.
9727 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
9728 * Makefile.am (INSTALL): Use the new macros.
9729 Use -o rather than --output, since "missing" does not grok --output.
9731 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9733 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
9734 comments do not always work. Never trust the exit status of
9735 `make -k'.
9737 2002-07-24 Kevin Ryde <user42@zip.com.au>
9739 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
9740 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.

9744 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
9745 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
9746 apparently treats PATH="nonexistent" as if it contained ".".
9747 Bug reported by Stefan `Sec' Zehl.
9749 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>

9868 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
9869 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
9870 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
9871 so that Emacs setups GNU style for perl-mode and cperl-mode.
9873 2002-06-27 Paul Eggert <eggert@twinsun.com>
9875 * config/install-sh: Quote $src. Prefer || to test's -o option,
9876 as per "Limitations of Builtins".
9877 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
9878 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
9880 * tests/mktests.sh: Use grep instead of fgrep, as per
9881 "Limitations of Builtins".
9883 2002-06-15 Paul Eggert <eggert@twinsun.com>
9885 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
9886 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
9887 so that we consistently test the just-built programs.
9888 * tests/wrappl.as: Likewise.
9890 2002-06-12 Paul Eggert <eggert@twinsun.com>
9892 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
9893 name, so that symlinks to 'autoconf' work properly. Bug reported
9894 by Bruno Haible.
9895 * bin/autoheader.in (AUTOM4TE): Likewise.
9896 * bin/autoreconf.in (autoconf, autoheader): Likewise.
9897 * bin/autoscan.in (autom4te): Likewise.

9900 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
9901 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
9902 on Solaris 2.5.1.
9904 2002-06-11 Andreas Schwab <schwab@suse.de>
9906 * doc/autoconf.texi: Add more dir entries.
9908 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
9910 * bin/autom4te.in ($cache): Don't define using `$me', the name
9911 of the cache should not depend on the name under which autom4te
9912 was installed.
9914 2002-06-07 Akim Demaille <akim@epita.fr>
9916 * tests/tools.at (autoconf: forbidden tokens, basic)

9923 _AC_LANG_PROGRAM_C_F77_HOOKS.
9925 2002-06-07 Akim Demaille <akim@epita.fr>
9927 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
9928 rename as...
9929 (AC_REPLACE_FNMATCH): this.
9930 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
9931 AC_FUNC_FNMATCH_GNU.
9933 2002-06-07 Akim Demaille <akim@epita.fr>
9935 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
9936 Rosetta Stone for Unix.
9938 2002-06-07 Akim Demaille <akim@epita.fr>
9940 * bin/autom4te.in (warn_forbidden): When rejecting a token,
9941 suggest m4_pattern_allow.
9942 Suggested by Adam J. Richter.
9944 2002-06-07 Akim Demaille <akim@epita.fr>
9946 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
9947 ac_config_libobj_dir.
9948 (AC_CONFIG_LIBOBJ_DIR): New.
9949 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
9950 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
9951 Use ac_config_libobj_dir to find the replacement files.
9952 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
9953 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
9954 (AC_REPLACE_FNMATCH_GNU): these.
9955 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
9956 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
9957 * tests/mktests.sh (ac_exclude_list): Don't check

9960 2002-06-06 Paul Eggert <eggert@twinsun.com>
9962 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
9963 if ln doesn't work.
9964 * NEWS: Likewise.
9965 * doc/autoconf.texi (Configuration Links): Likewise.
9966 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
9968 2002-06-05 Paul Eggert <eggert@twinsun.com>
9970 * config/config.guess, config/config.sub, config/texinfo.tex:
9971 Update from masters.
9973 2002-05-29 Paul Eggert <eggert@twinsun.com>
9975 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
9976 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
9977 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):

9996 * NEWS, doc/autoconf.texi (Particular Types): Document it.
9997 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
9998 instead of AC_MBSTATE_T, which never existed.
10000 2002-05-23 Akim Demaille <akim@epita.fr>
10002 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
10003 version of Autoconf that is discussed.
10005 2002-05-22 Paul Eggert <eggert@twinsun.com>
10007 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
10008 from the default list of compilers to try. Suggested by
10009 Kate Hedstrom.
10010 * NEWS: Document the above.
10011 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
10013 2002-05-17 Paul Eggert <eggert@twinsun.com>
10015 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
10016 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
10017 This improves on an earlier suggestion by H. Peter Anvin.
10019 2002-05-16 Paul Eggert <eggert@twinsun.com>
10021 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
10022 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
10023 Both macros now accept an optional source-dir arg.
10024 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
10026 * NEWS: Document this.
10027 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
10029 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
10030 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
10031 not for GNU extensions; this undoes part of the 2000-11-03 change,
10032 reverting to 2.13-compatible behavior.
10033 Add new optional argument DIR.
10034 (AC_FUNC_FNMATCH_GNU): New macro.
10036 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
10038 2002-05-08 Paul Eggert <eggert@twinsun.com>
10040 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
10041 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
10042 and it causes a 'test' syntax error if it fails.
10043 Bug reported by Stephen Gildea.
10045 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
10046 If prototypes are supported, use them to check this at compile-time,
10047 instead of trying to check it at run-time. If we must do a run-time
10048 check, assume that setvbuf is standard when cross-compiling, as
10049 nonstandard setvbuf occurs only on ancient and unlikely hosts.
10050 Bug reported by Paul D. Smith.
10052 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
10053 argument specifying location of getloadavg.c. This removes a
10054 FIXME. This idea was taken from Jim Meyering's implementation in
10055 textutils.
10056 * doc/autoconf.texi (Particular Functions): Document this.
10057 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
10058 that's what the code does; this fixes a bug reported by
10059 Paul D. Smith.
10061 2002-05-03 Akim Demaille <akim@epita.fr>
10063 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
10064 autopoint instead of gettextize.
10065 ($uses_alocal): Rename as...
10066 ($uses_aclocal): this.
10067 * doc/autoconf.texi (autoreconf Invocation): Adjust.
10068 Suggested by Bruno Haible.
10070 2002-05-03 Akim Demaille <akim@epita.fr>
10072 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
10074 2002-04-29 Paul Eggert <eggert@twinsun.com>
10076 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
10077 files to be 1 second older; just set them to be the same time.
10078 Also, sleep 1 second after the first aclocal, to work around
10079 problems with sub-second time stamps on the input files.
10081 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
10083 * doc/autoconf.texi: Mention "set -e -x" lossage
10084 under node "Limitations of Builtins".
10086 2002-04-29 Akim Demaille <akim@epita.fr>
10088 * doc/install.texi: Better wording for setting variables when
10089 running configure.
10090 From Christian Cornelssen.
10092 2002-04-29 Akim Demaille <akim@epita.fr>
10094 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
10095 of lack of $LINENO support, then the test will compare the $LINENO
10096 in testsuite vs. the lineno in the test file. This is wrong, of
10097 course.
10098 Be sure to protect it.
10099 Reported by Patrick Welche.
10101 2002-04-25 Akim Demaille <akim@epita.fr>
10103 * doc/autoconf.texi (Obsolete Macros): Typo.
10104 Reported by Vladimir Volovich.
10106 2002-04-25 Akim Demaille <akim@epita.fr>
10108 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
10109 than some of the input files, hence, on the second run of aclocal,
10110 if some of its input are younger, make them older.
10111 Suggested by Paul Eggert.
10113 2002-04-25 Akim Demaille <akim@epita.fr>
10115 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
10116 Thanks to Paul Eggert.
10118 2002-04-25 Akim Demaille <akim@epita.fr>
10120 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
10121 and ac_subst_vars be sh variables containing the list of
10122 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
10123 DEFAULT diversion.
10124 (_AC_INIT_PREPARE): Use them to log them.
10125 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
10126 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
10127 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
10128 _AC_SUBST_FILES and _AC_SUBST_VARS.
10129 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
10131 2002-04-24 Akim Demaille <akim@epita.fr>
10133 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
10134 autoheader, so that automake does not complain about a missing
10135 config.h.in that was to be created.
10137 2002-04-23 Akim Demaille <akim@epita.fr>
10139 * bin/autoheader.in (parse_args): --warning takes an argument.
10140 Fixes PR/220.
10142 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
10144 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

10155 2002-04-22 Akim Demaille <akim@epita.fr>
10157 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
10158 comma.
10159 Reported by Gregory Giannoni.
10161 2002-04-22 Akim Demaille <akim@epita.fr>
10163 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
10164 Fixes false failures on Darwin.
10166 2002-04-21 Paul Eggert <eggert@twinsun.com>
10168 * TODO, bin/autoupdate.in, doc/autoconf.texi,
10169 lib/autoconf/general.m4, lib/autoconf/libs.m4,
10170 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,
10171 tests/tools.at: Minor spelling and grammar fixes.
10173 2002-04-20 Paul Eggert <eggert@twinsun.com>
10175 * doc/autoconf.texi (Shell Substitutions): Fix typos in yesterday's
10176 ZSH_VERSION fixes. Bug reported by Raja R Harinath.
10177 * lib/autotest/general.m4 (AT_INIT): Likewise.
10178 * tests/atgeneral.m4 (AT_INIT): Likewise.
10180 2002-04-19 Paul Eggert <eggert@twinsun.com>

10188 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
10189 Minor spelling and grammar fixes.
10191 * doc/autoconf.texi: Follow the outline suggested in the GNU
10192 Sample Texts sections of the Texinfo 4.2 manual. Most
10193 importantly, this makes sure that the copyright notices appear in
10194 all output formats. You probably need Texinfo 4.2 to generate
10195 the manual now.
10197 Fix some bugs when using "$@" when there might be zero positional
10198 arguments in cases where this matters.
10200 * bin/autoconf.as: Rewrite so that the problem does not come up.
10201 * lib/autoconf/programs.m4 (AC_CHECK_PROG): Likewise.

10212 * doc/autoconf.texi (Shell Substitutions): Document the problem.
10214 * lib/autotest/general.m4 (AT_INIT):
10215 Use Zsh alias to work around problem.
10216 * tests/atgeneral.m4 (AT_INIT): Likewise.
10218 * tests/c.at: We can't have zero arguments, so remove workaround
10219 that is not portable to Zsh.
10221 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
10223 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
10224 from aclocal.m4 too.
10226 2002-04-12 Akim Demaille <akim@epita.fr>

10230 2002-04-10 Akim Demaille <akim@epita.fr>
10232 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
10233 workaround for ${1+"$@"}.
10234 * doc/autoconf.texi (Shell Substitutions): Explain it.
10235 From Oliver Kiddle and Peter Stephenson.
10237 Have M4sh perform minimal shell sanitizing.
10239 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
10240 part into...
10241 (_AS_PREPARE): this new macro.
10242 (AS_PREPARE): New.
10243 (AS_INIT): Invoke AS_SHELL_SANITIZE.
10244 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
10246 Adjust Autoconf and Autotest.
10248 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
10249 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
10250 * lib/autotest/general.m4 (AT_INIT): Likewise.
10251 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10252 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
10253 AS_SHELL_SANITIZE.
10255 Use this M4sh to generate Autoconf's shell scripts.
10257 * tests/wrapsh.as: New, precursor of wrapsh.in.
10258 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
10259 on Autotest and M4sh.
10260 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
10261 (wrapsh.in): New target.
10262 * bin/autoconf.as: New, precursor of autoconf.in.
10263 (autoconf.in): New target.
10265 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
10267 * doc/autoconf.texi (Limitations of Make): Mention the issue
10268 with indented comments in rules.
10270 2002-04-09 Andreas Schwab <schwab@suse.de>
10272 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
10273 ac_top_builddir when setting ac_abs_top_builddir.
10275 2002-04-06 Kevin Ryde <user42@zip.com.au>
10277 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
10278 (Portable Shell): Cross reference to Systemology.
10280 2002-04-05 Akim Demaille <akim@epita.fr>
10282 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
10283 directories when descending in a SUBDIRS.
10284 Reported by Ezra Peisach.
10286 2002-04-04 Andreas Schwab <schwab@suse.de>
10288 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
10289 contains no literal separators.
10291 2002-04-03 Akim Demaille <akim@epita.fr>
10293 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
10294 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
10295 Use dnl, not the KILL diversion.
10296 Extracted from...
10297 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
10298 (AC_CONFIG_LINKS): here.
10299 Adjust.
10300 Don't use the KILL diversion, as it kills spurious output, which
10301 results in failures being hidden.
10302 Use m4_defn where appropriate.
10303 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
10304 after the second argument.
10305 Use m4_defn.
10306 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
10307 syntax, as it is provided by M4sugar.
10308 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
10310 2002-04-03 Andreas Schwab <schwab@suse.de>
10312 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
10313 expanded if $# <= 2.
10315 * bin/autoreconf.in (autoreconf): Run automake after rerunning
10316 aclocal.
10318 2002-04-03 Akim Demaille <akim@epita.fr>

10321 (_AC_COMPILER_EXEEXT_REJECT): New.
10322 Also recognize *.bb and *.bbg as compilation byproducts.
10323 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
10324 (_AC_COMPILER_OBJEXT): Use them.
10325 Fixes Debian #138666.
10327 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
10329 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
10331 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
10332 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
10333 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
10334 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
10335 (AC_C_CONST): Same.
10336 (AC_C_INLINE): Same.
10337 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
10338 * doc/autoconf.texi, NEWS: Document.
10339 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
10340 AC_C_CROSS.

10347 2002-03-28 Kevin Ryde <user42@zip.com.au>
10349 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
10350 to avoid versions of HP C which don't allow that.
10352 2002-03-27 Paul Eggert <eggert@twinsun.com>
10354 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
10355 (AS_SHELL_SANITIZE): Invoke it.
10356 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
10358 2002-03-26 Akim Demaille <akim@epita.fr>
10360 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
10362 2002-03-26 Akim Demaille <akim@epita.fr>
10364 * doc/autoconf.texi (Introduction): The GNATS base moved.
10366 2002-03-25 Paul Eggert <eggert@twinsun.com>
10368 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
10369 as POSIX requires, as it doesn't work with Zsh.
10370 * doc/autoconf.texi (Assignments): Document the problem.
10372 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
10374 * doc/autoconf.texi (Limitations of Make): Mention more issue
10375 about VPATH, overriding of macros in sub-makes, and handling of
10376 SHELL.
10378 2002-03-21 Paul Eggert <eggert@twinsun.com>
10380 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
10381 problem with here-document buffer boundaries.
10383 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
10384 when reinvoking the shell, to work around problems with installers
10385 who put strange things like "cd" commands in their environments.
10387 2002-03-19 Akim Demaille <akim@epita.fr>
10389 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
10390 From Aaron Ucko.
10392 2002-03-19 Akim Demaille <akim@epita.fr>
10394 * bin/autoscan.in (scan_file): Specify the location in `&used'
10395 invocations.
10396 From Nicolas Joly.
10398 2002-03-19 Akim Demaille <akim@epita.fr>
10400 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
10401 From Nishio Futoshi.
10403 2002-03-19 Akim Demaille <akim@epita.fr>
10405 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
10407 2002-03-18 Paul Eggert <eggert@twinsun.com>
10409 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
10410 (Limitations of Usual Tools): Add mkdir section.
10412 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
10413 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
10414 back on AS_DIRNAME to compute prefixes otherwise; this is
10415 roughly what mkinstalldirs does. That way, we need not have
10416 our own filename disassembler. The old disassembler did not
10417 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
10419 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
10420 Create at_test_all by a series of assignments,
10421 not by a single assignment of a long string. The latter causes ksh
10422 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
10423 presumably because of a buffer overrun.
10425 2002-03-14 Paul Eggert <eggert@twinsun.com>
10427 * lib/autotest/general.m4 (at_times_skip):
10428 Renamed from at_times. Now a boolean.
10429 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
10430 says 'times: not found'.
10432 2002-03-14 Akim Demaille <akim@epita.fr>
10434 * bin/autoreconf.in (&study_gettextize): New.
10435 (&autoreconf): Handle newest gettextize.
10436 Rerun aclocal if needed.
10437 Suggested by Andreas Schwab.
10439 2002-03-13 Akim Demaille <akim@epita.fr>
10441 * doc/autoconf.texi (Special Shell Variables): More about IFS.
10443 2002-03-13 Akim Demaille <akim@epita.fr>
10445 * doc/autoconf.texi (Header Portability): New.
10446 Add information about stdint.h and inttypes.h from Paul Eggert.
10448 2002-03-13 Akim Demaille <akim@epita.fr>
10450 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
10451 -p'.
10452 From Bob Proulx.
10454 2002-03-12 Akim Demaille <akim@epita.fr>
10456 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
10457 m4_require.
10459 2002-03-11 Andreas Schwab <schwab@suse.de>
10461 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
10462 does not do it if --with-lispdir is given.
10464 2002-03-08 Akim Demaille <akim@epita.fr>
10466 Version 2.53.
10468 2002-03-08 Akim Demaille <akim@epita.fr>
10470 * doc/autoconf.texi (Subdirectories): Clarify that the
10471 subdirectory should exist.
10473 2002-03-08 Akim Demaille <akim@epita.fr>
10475 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
10477 2002-03-08 Akim Demaille <akim@epita.fr>
10479 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
10480 aliases the actual variables, and modifications of the former
10481 affect the latter.
10483 2002-03-08 Akim Demaille <akim@epita.fr>
10485 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
10486 because of C-c: have m4 output in tmp files, then mv them.
10488 2002-03-08 Akim Demaille <akim@epita.fr>
10490 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
10491 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
10492 * bin/ifnames.in: Copyright update.
10494 2002-03-08 Akim Demaille <akim@epita.fr>
10496 * doc/autoconf.texi (Invoking autom4te): New.
10498 2002-03-05 Akim Demaille <akim@epita.fr>
10500 * doc/autoconf.texi (Specifying Names): Clarification suggested by
10501 Kevin Ryde.
10503 2002-03-05 Akim Demaille <akim@epita.fr>
10505 Version 2.52i.
10507 2002-03-04 Akim Demaille <akim@epita.fr>
10509 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
10510 * lib/autoconf/general.m4 (AC_INIT): More informative error
10511 message for LIBOBJ.
10513 2002-03-04 Akim Demaille <akim@epita.fr>
10515 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
10516 parallel builds.
10518 2002-03-04 Akim Demaille <akim@epita.fr>
10520 * doc/autoconf.texi (Transforming Names): Equality between target
10521 and host is irrelevant.
10522 (Specifying Names, Canonicalizing): Remove all references to the
10523 backward compatibility hooks. Rather, collect them all into...
10524 (Hosts and Cross-Compilation): this new section.
10525 * doc/install.texi (System Type): Ditto.
10526 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
10527 that `--host' implies cross-compilation.
10529 2002-03-04 Akim Demaille <akim@epita.fr>
10531 * doc/autoconf.texi (Evaluation Macros): New.
10532 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
10533 useless.
10534 (_m4_foreach): Define the variant with immediate evaluation so
10535 that it contains exactly the items, not an expression which
10536 evaluation is the current item.
10537 (m4_re_string, m4_re_word): Don't over quote them.
10539 2002-03-04 Akim Demaille <akim@epita.fr>
10541 Instead of having stacking `shift's evaluated at the end, let
10542 `foreach' loops immediately evaluate them.
10544 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
10545 $*. This is the n-th time I change my mind, but hopefully this is
10546 the last...
10547 (m4_lquote): New.
10548 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
10549 efficient.
10550 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
10551 it was only a hack for m4_text_wrap.
10552 (m4_car2): Remove, replaced by...
10553 (m4_cdr): New.
10554 (_m4_foreach): Adjust.
10555 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
10556 m4_bpatsubst for clarification.

10596 Version 2.52h.
10598 2002-02-07 Akim Demaille <akim@epita.fr>
10600 Fix Autoconf PR/209.
10601 Also reported by Frank Denis.
10603 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
10605 2002-02-07 Akim Demaille <akim@epita.fr>
10607 Fix Autoconf PR/207:
10608 AC_PREFIX_PROGRAM fails with dashed program names
10610 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
10611 variable when looking for the prefix program.
10612 Now it also works for shell variables.

10622 case/esac, some shells don't support it.
10623 Reported by Zack Weinberg.
10624 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
10626 2002-02-06 Akim Demaille <akim@epita.fr>

10642 not unsigned long.
10643 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
10644 cross-compilers, too. This undoes some of the most recent change
10645 to this file.
10647 2002-02-05 Akim Demaille <akim@epita.fr>
10649 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

10657 2002-02-05 Akim Demaille <akim@epita.fr>
10659 * lib/freeze.mk: New.
10661 2002-02-05 Akim Demaille <akim@epita.fr>
10663 Implement `autom4te --freeze'.
10665 * bin/autom4te.in (&freeze): New.
10666 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
10667 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
10669 2002-02-05 Akim Demaille <akim@epita.fr>
10671 * bin/autom4te.in (&parse_args): Implement `frozen files are
10672 optional are the sum of the previous files on the command line'.
10673 Also, pass `--reload-state=' on them, so...
10674 (handle_m4): don't.
10675 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
10676 (M4sh): Rely on M4sugar.
10677 (Autotest, M4sh, M4sugar): Use frozen files.
10679 2002-01-31 Akim Demaille <akim@epita.fr>
10681 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
10682 * doc/autoconf.texi (Initializing configure): Adjust.
10684 2002-01-30 Akim Demaille <akim@epita.fr>
10686 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
10687 alphanumeric to `-' instead of `_'.
10689 2002-01-30 Akim Demaille <akim@epita.fr>
10691 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
10692 for plain code, the other for cross-compilation code. The latter
10693 is now run with GCC only.
10694 * doc/autoconf.texi (Compilers and Preprocessors): New.
10696 2002-01-30 Akim Demaille <akim@epita.fr>
10698 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
10699 values.
10700 * doc/autoconf.texi (Initializing configure): Explain how to
10701 change AC_INIT default values.
10703 2002-01-29 Akim Demaille <akim@epita.fr>
10705 * tests/torture.at (Configuring subdirectories): Use configure.in,
10706 so that aclocal 1.4 works.
10707 Reported by Alexandre Duret-Lutz and Larry Schmitt.
10709 2002-01-28 Akim Demaille <akim@epita.fr>
10711 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
10712 needs an argument.
10714 2002-01-28 Akim Demaille <akim@epita.fr>
10716 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
10717 AUTOTEST_PATH *after* it was set.
10718 Don't put `.' in the PATH: the user should be precise and `./' if
10719 needed. In addition, given that the test suite does some `cd', if
10720 `.' is in the path, the `tested programs' sections will report
10721 programs found in the test suite's directory, while during the
10722 tests (performed in their own directory), these programs are no
10723 longer visible. In other words, the results is confusing and
10724 useless.
10725 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
10727 2002-01-24 Akim Demaille <akim@epita.fr>
10729 Version 2.52g.
10731 2002-01-24 Akim Demaille <akim@epita.fr>
10733 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
10734 * doc/autoconf.texi: Finally add Akim as an author.
10736 2002-01-24 Akim Demaille <akim@epita.fr>
10738 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
10739 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
10740 Bourne. Use /bin/sh.
10741 From Andreas Buening.
10743 2002-01-24 Akim Demaille <akim@epita.fr>
10745 * config/config.guess, config/config.sub, config/texinfo.tex:
10746 Update from masters.
10748 2002-01-24 Akim Demaille <akim@epita.fr>
10750 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.

10752 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
10753 * config/missing.m4, config/sanity.m4, config/select.m4,
10754 * config/strip.m4: Remove, to ease sync'ing with any version of
10755 Automake.
10757 2002-01-24 Akim Demaille <akim@epita.fr>
10759 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
10760 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
10761 Reported by Geir Ove Myhr.
10763 2002-01-21 Akim Demaille <akim@epita.fr>
10765 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
10767 2002-01-21 Akim Demaille <akim@epita.fr>
10769 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
10770 message on invalid options.
10771 * bin/autom4te.in (parse_args): Don't use
10772 Autoconf::General::getopt with non valid options.
10774 2002-01-17 Jim Meyering <meyering@lucent.com>
10776 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
10777 $ac_cv_exeext so we don't use an old, invalid, cached value.
10779 2002-01-11 Akim Demaille <akim@epita.fr>
10781 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
10782 Meyering.

10784 limitation.

10788 2002-01-06 Akim Demaille <akim@epita.fr>
10790 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
10791 package.m4, since is really depends upon configure.ac, not
10792 configure.
10793 * doc/autoconf.texi (testsuite Scripts): Adjust.
10794 * tests/Makefile.am (package.m4): New.
10795 EXTRA_DIST it since its a source.
10797 2002-01-06 Akim Demaille <akim@epita.fr>
10799 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
10800 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
10801 and PACKAGE_BUGREPORT from here...
10802 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
10803 arguments.
10804 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
10805 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
10806 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
10807 * tests/tools.at (autoheader): Adjust.
10808 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
10810 2002-01-06 Akim Demaille <akim@epita.fr>

10814 2002-01-03 Akim Demaille <akim@epita.fr>
10816 * doc/autoconf.texi (Output): Improved wording regarding use of
10817 AC_OUTPUT.
10818 From Olly Betts.
10820 2001-12-18 Kevin Ryde <user42@zip.com.au>
10822 * doc/autoconf.texi (Function Portability): Add notes on sscanf
10823 sometimes needing writable input.
10825 2001-12-17 Jim Meyering <meyering@lucent.com>
10827 * doc/autoconf.texi (New Macros): Tweak wording.
10829 2001-12-14 Akim Demaille <akim@epita.fr>
10831 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
10832 trailing files, don't apply `-rf' to files which might not be
10833 created by configure (core, core.*, and *.core), but just `rm -f'.
10834 Suggested by Jonathan Kamens.
10836 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
10838 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
10840 2001-12-14 Akim Demaille <akim@epita.fr>
10842 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
10844 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
10846 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
10847 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
10848 abs_srcdir, top_srcpath to abs_top_srcdir.
10849 (_AC_OUTPUT_FILES): Adjust.
10850 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
10851 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
10852 * tests/wrappl.in, tests/wrapsh.in: Adjust.
10854 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
10856 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
10857 C/Fortran linking on HP/UX, by extracting the Fortran library
10858 search path from the LPATH line in the $F77 -v output.
10860 2001-12-12 Kevin Ryde <user42@zip.com.au>
10862 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
10863 forbidden file descriptors table.
10865 2001-11-26 Akim Demaille <akim@epita.fr>
10867 * bin/autoscan.in (%c_keywords): Build it at top level.
10868 Map to 1 in order to simplify its uses.
10870 2001-11-26 Akim Demaille <akim@epita.fr>
10872 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
10873 Remove $filepath, useless.
10874 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10875 variables, they are really part of the tokens.
10876 Split the input line on spaces and then look for tokens.
10877 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10878 because of `lex$U.$(OBJEXT)'.
10879 (&scan_files): Use "@list" instead of join.
10880 * doc/Makefile.am (CLEANFILES): Add *.fns.
10882 2001-11-26 Akim Demaille <akim@epita.fr>
10884 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
10885 Remove, replaced by...
10886 * tests/wrappl.in: Be common for all the Perl executables.
10887 In particular autoscan and autoheader want -I.
10888 * configure.ac: Adjust.
10889 * lib/autoscan/headers: errno.h is portable.
10891 2001-11-26 Akim Demaille <akim@epita.fr>
10893 * bin/autoscan.in (used): New.
10894 Use it.
10896 2001-11-26 Akim Demaille <akim@epita.fr>
10898 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
10899 directives.
10900 (&scan_sh_file): Remove a duplicate pattern.
10901 (&check_configure_ac): Use long options.
10902 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
10904 2001-11-26 Akim Demaille <akim@epita.fr>
10906 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
10907 Before, having a line containing the opening of a multi line
10908 comment made the whole line be ignored.
10910 2001-11-26 Akim Demaille <akim@epita.fr>
10912 * doc/autoconf.texi (Using an Autotest Test Suite): New.
10913 (testsuite Scripts): Be one of its subsection.
10914 (Autotest Logs): New.
10916 2001-11-26 Akim Demaille <akim@epita.fr>
10918 Test groups are now run two directories deeper.
10920 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
10921 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
10922 at_top_builddir.
10923 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10924 top_srcdir, builddir and top_builddir.
10925 Use `at_*dir' relatively to the directory containing the
10926 suite, use `*dir' when relatively to the current group dir.
10928 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
10930 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
10931 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
10932 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
10933 spelling errors.
10935 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10937 * doc/autoconf.texi (Using System Type): Add an example of `case
10938 $host' usage so people quit using `case $target' everywhere.
10940 2001-11-22 Akim Demaille <akim@epita.fr>
10942 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10943 spotted by Jim Meyering.
10945 2001-11-16 Paul Eggert <eggert@twinsun.com>
10947 This patch implements a `long double' suggestion by Oliver Kiddle.
10949 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10950 static, to catch errors if the value isn't known at compile-time
10951 and the compiler supports dynamic arrays. Change its name from
10952 `_array_' to `test_array' to avoid potential name clashes.
10953 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10954 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10955 better than double. Catch a bug in GCC 2.95.2 x86.
10956 * doc/autoconf.texi (C Compiler): Document the above.
10957 * NEWS: Likewise.
10959 2001-11-13 Akim Demaille <akim@epita.fr>
10961 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10962 hand.
10963 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10965 2001-11-13 Akim Demaille <akim@epita.fr>
10967 * lib/autotest/general.m4 (AT_INIT): After having run the test
10968 group, go back to the initial directory, not to at_suite_dir.
10970 2001-11-13 Akim Demaille <akim@epita.fr>
10972 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10973 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10974 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10975 option.
10976 (AT_CHECK_CONFIGURE): Use absolute paths.
10977 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10978 The problem is still the old one: there is no means in M4 (that I
10979 know about) to create a defining macro, because there is no means
10980 to create `$1' etc., therefore, the defining macro ``swallows''
10981 all the arguments meant to the defined macro.
10983 2001-11-13 Akim Demaille <akim@epita.fr>
10985 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10986 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10987 configure.ac.
10988 * tests/aclocal.m4: Remove, as it is no longer used.
10990 2001-11-13 Akim Demaille <akim@epita.fr>
10992 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10993 variable names when referring to a single test group, or to
10994 `suite' when referring to the whole test suite.
10995 `at_last_test' is removed: m4 compute at_format itself.
10996 (at_stdout, at_stder1, at_stderr): New variables.
10997 (AT_CHECK): Use them.
10999 2001-11-13 Akim Demaille <akim@epita.fr>
11001 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
11002 in PATH.
11003 Create `testsuite.dir/003/run' instead of `testsuite.003'.
11004 Do it as soon as a test fails, don't wait till the end of the test
11005 suite.
11006 Don't remove $as_me.[0-9]*, since these files no longer exist.
11008 2001-11-13 Akim Demaille <akim@epita.fr>
11010 * tests/tools.at: Use absolute paths, since we are no longer run
11011 in place.
11013 2001-11-13 Akim Demaille <akim@epita.fr>
11015 Now that tests are running in their own private dir, there is no
11016 need to list the files to remove at the end of tests groups.
11018 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
11019 (AT_data_files, at_data_files): Remove.
11020 (AT_CLEANUP, AT_DATA): Simplify.
11021 (AT_INIT): Adjust.
11022 Remove the group dir if !debug && !failed.
11023 * tests/atspecific.m4: Adjust.
11025 2001-11-13 Akim Demaille <akim@epita.fr>
11027 Start a new layout for Autotest: `testsuite' creates
11028 `testsuite.dir' in which the at-check-line etc. files are to be
11029 found, and `testsuite.dir/003' where the test group 3 is run.
11031 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
11032 at_check_line_file, at_format, at_test_normalized, at_group_dir
11033 are new variables.
11034 Create the directories.
11035 Use absolute paths for at- files.
11036 (AT_CHECK): Adjust.
11038 2001-11-11 Michael Matz <matz@kde.org>
11040 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
11041 (m4_car2): New.
11042 (m4_car): Properly quote arguments.
11044 2001-11-13 Akim Demaille <akim@epita.fr>
11046 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
11047 with stricter rules on LIBOBJS.
11049 2001-11-12 Paul Eggert <eggert@twinsun.com>
11051 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
11052 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
11053 __PROTOTYPES too.
11055 2001-11-12 Akim Demaille <akim@epita.fr>
11057 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
11059 2001-11-12 Akim Demaille <akim@epita.fr>
11061 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
11062 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
11063 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11064 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
11065 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
11066 specify to what the macro should be defined (typically to 1).
11068 2001-11-12 Akim Demaille <akim@epita.fr>
11070 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
11071 From Jim Meyering.
11073 2001-11-12 Akim Demaille <akim@epita.fr>
11075 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11076 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
11077 definition used by Automake where LEX is +/- "${missing} lex" and
11078 `missing' itself contains variables.
11080 2001-11-12 Akim Demaille <akim@epita.fr>
11082 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
11083 Now that M4sh pushes BODY, the comments were output at the end of
11084 the test suites.
11086 2001-11-08 Akim Demaille <akim@epita.fr>
11088 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
11089 that we can trace macros from aclocal.m4.
11090 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
11091 obsoleted, and redirect to the former anyway.
11092 Reported by Ralf Corsepius.
11094 2001-11-08 Akim Demaille <akim@epita.fr>
11096 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
11097 processed only if present.
11098 * tests/torture.at (Configuring subdirectories): Use autoreconf
11099 instead of successive calls to autoconf.
11100 Add a nonexistent subdirectory to exercise the patch above.
11101 Reported by Ralf Corsepius.
11103 2001-11-08 Kevin Ryde <user42@zip.com.au>
11105 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
11106 doesn't accept .S files.
11108 2001-11-07 Akim Demaille <akim@epita.fr>
11110 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
11111 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
11112 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
11113 * bin/autom4te.in (warn_forbidden): New.
11114 (handle_output): Use it.
11115 Read m4_pattern_forbid with messages.
11117 2001-11-05 Akim Demaille <akim@epita.fr>
11119 * bin/autom4te.in (--normalize): Remove.
11120 * lib/autom4te.in: Adjust.
11122 2001-11-05 Akim Demaille <akim@epita.fr>
11124 * tests/Makefile.am (testsuite): Rename this target as...
11125 ($(TESTSUITE)): this.
11126 From Nicolas Joly.
11128 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
11130 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing

11144 * lib/Autom4te/General.pm: (&catfile, &canonfile)
11145 (&file_name_is_absolute): New, wrappers around routines from
11146 File::Spec.
11147 Use and export them.
11148 (&find_configure_ac): Optionally take a directory where to look at.
11149 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
11150 the arguments.
11151 Default @ARGV to `.', not find_configure_ac.
11152 (&autoreconf): Argument is a directory.

11159 (@export_forward_subs): New.
11160 Add basename, dirname, and fileparse.
11161 (@EXPORT): Adjust.
11162 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
11163 Don't look for aclocal flags if we already know aclocal is not
11164 used.
11165 Move aclocal.m4t only if it exists.
11166 Reported by Ezra Peisach.
11168 2001-11-03 Akim Demaille <akim@epita.fr>
11170 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
11171 passed on command line, defaulting to ./configure.ac if present.
11172 (&maybe_autoreconf, File::Find): Remove, unused.
11173 (&autoreconf): If autoconf is not used, don't try to trace.
11175 2001-11-02 Akim Demaille <akim@epita.fr>
11177 * configure.ac: Bump to 2.52g.
11179 2001-11-02 Akim Demaille <akim@epita.fr>
11181 Version 2.52f.
11183 2001-11-02 Akim Demaille <akim@epita.fr>
11185 * config/config.guess, config/config.sub, doc/standards.texi:
11186 * config/lispdir.m4: Update from masters.
11187 * configure.ac: Bump to 2.52f.
11189 2001-11-02 Akim Demaille <akim@epita.fr>
11191 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
11192 Don't run aclocal when aclocal.m4 is not from aclocal.
11193 From Ezra Peisach.
11194 Don't run libtoolize and gettextize if --install is not given.
11196 2001-11-01 Paul Eggert <eggert@twinsun.com>
11198 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
11199 be invoked before _AS_LINENO_PREPARE.
11200 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
11201 than character ranges.
11203 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
11204 invoking AS_BASENAME. Set the locale variables to 'C' if
11205 possible, as POSIX requires this to get the traditional
11206 behavior.
11207 * doc/autoconf.texi (Special Shell Variables): Describe the above.
11209 2001-10-31 Paul Eggert <eggert@twinsun.com>
11211 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
11212 with {}, as that triggers a bug in Bash 2.05.
11214 (_AS_LINENO_PREPARE): Use Sed rather than
11215 Awk. Fix the sed prepass to work even if there are multiple
11216 instances of $LINENO on the same line. Do not substitute for
11217 other variables like $LINENOT. Do not check file dates; such a
11218 check is unreliable on sufficiently fast machines, and removing
11219 the check makes the code simpler and more reliable. Check for
11220 output and chmod failures.
11222 * doc/autoconf.texi (Special Shell Variables): Document
11223 the above.
11225 2001-10-31 Akim Demaille <akim@epita.fr>
11227 * tests/Makefile.am (atconfig): Remove this target, Automake
11228 handles it now.
11230 2001-10-31 Akim Demaille <akim@epita.fr>
11232 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
11233 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
11234 provided, while it is optional.
11235 * configure.ac: Adjust.
11237 2001-10-26 Paul Eggert <eggert@twinsun.com>
11239 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
11240 lib/Autom4te/Struct.pm:
11241 Require Perl 5.005_03 instead of just 5.005, as some tests fail
11242 with 5.005_02.
11244 * doc/autoconf.texi (Special Shell Variables): Document some
11245 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
11247 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
11248 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
11249 eval $LINENO is not portable in practice.
11251 2001-10-24 Akim Demaille <akim@epita.fr>
11253 * lib/Autom4te/General.pm (backname): New.
11255 2001-10-24 Akim Demaille <akim@epita.fr>
11257 * m4/: Remove, merged into...
11258 * config/: here.
11260 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
11262 * doc/autoconf.texi (Shellology): Mention the problems with bash
11263 2.05's use of ANSI quoting in its `set' builtin.
11265 2001-10-22 Paul Eggert <eggert@twinsun.com>
11267 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
11268 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
11269 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
11270 POSIX decided to standardize on the int flavor of strerror_r.
11271 Always do char* test, as there's no reason not to.
11272 Assign to a char* var, to catch strerror_r that returns int*.
11274 * doc/autoconf.texi (Particular Functions):
11275 Document the above changes. Also, document the fact that
11276 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
11278 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
11280 2001-10-20 Akim Demaille <akim@epita.fr>
11282 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
11283 the executable was missing from the log.
11285 2001-10-20 Akim Demaille <akim@epita.fr>
11287 * lib/Autom4te/General.pm (&update_file): If destination is
11288 unchanged, remove the source.
11289 (&up_to_date_p): Don't be verbose, be debug.
11290 * bin/autoreconf.in: No longer support --m4dir.
11291 (&autoreconf): Display the full path of the configure.ac we are
11292 studying.
11293 Trace it only once.
11294 Be sure to honor --force with gettextize.
11295 Always run aclocal.
11296 * doc/autoconf.texi: Adjust.
11298 2001-10-20 Akim Demaille <akim@epita.fr>
11300 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
11301 Remove, dead.
11302 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
11303 `intl' is already present, as it refuses unless --force.
11304 (&parse_args): Use -I, --include instead of the old Autoconf
11305 options.
11306 ($localdir, $autoconf_dir): Remove.
11307 (@include): New.
11308 (&maybe_autoreconf): New, to preserve $_ for File::Find.
11310 2001-10-19 Jens Petersen <petersen@redhat.com>
11312 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

11317 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
11318 file in @configure_input@.
11319 Don't mention `automatically' in addition to `generated'.
11320 * tests/torture.at (#define header templates): Adjust.
11322 2001-10-19 Akim Demaille <akim@epita.fr>
11324 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
11325 comment, explain how to install automatic mode selection.
11326 From Russ Allbery.
11328 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
11330 * bin/autoreconf.in (autoreconf): Display the path to the
11331 configure.ac being studied.
11333 2001-10-18 Paul Eggert <eggert@twinsun.com>
11335 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
11336 long, to work around a bug in the HP C compiler version HP92453-01
11337 B.11.11.23709.GP.
11339 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
11340 (AS_BASENAME_EXPR): New macro.
11341 (AS_BASENAME_SED): Do not assume GNU sed semantics.
11342 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
11343 and fall back on 'sed' only if the other two fail. This makes
11344 AS_BASENAME act more like AS_DIRNAME.
11345 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
11346 contains white space.
11347 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
11348 Use AS_DIRNAME, since I think it's now DOS-friendly.
11349 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
11350 Allow "dirname //FOO" to return either / or //, as POSIX allows
11351 either behavior.
11353 2001-10-10 Akim Demaille <akim@epita.fr>
11355 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
11356 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
11357 From Eric Sharkey.
11359 2001-10-10 Akim Demaille <akim@epita.fr>
11361 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
11362 m4_define, since...
11363 (_AS_ECHO_N): AS_REQUIREs it.
11365 2001-10-10 Akim Demaille <akim@epita.fr>

11401 bother with $force since...
11402 * lib/Autom4te/General.pm: does.
11404 2001-10-08 Akim Demaille <akim@epita.fr>
11406 * bin/autoreconf.in: Rewrite in Perl.
11407 * configure.ac: Adjust.

11479 * tests/base.at: Adjust the tests to use AS_INIT.
11480 * tests/tools.at (AT_DATA_FORBIDDEN): New.

11491 empty, and if we can find a shell that does support LINENO,

11493 ourselves with CONFIG_SHELL.
11495 2001-10-05 Paul Eggert <eggert@twinsun.com>
11497 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
11498 doesn't exist. Remove *.tmp, as a .tmp file is created during the
11499 build of $(TESTSUITE).
11501 2001-10-05 Akim Demaille <akim@epita.fr>
11503 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

11568 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
11569 Don't use nested parenthesization. This patch was originally
11570 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
11571 but somehow it didn't get incorporated then.
11572 * doc/autoconf.texi (Limitations of Usual Tools):
11573 Clarify remark about sed and nested parenthesization.
11575 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
11576 Report an error if the size cannot be determined even though
11577 the type exists.
11578 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11579 Check for `expr' arithmetic overflow, and for compilation failure,
11580 and invoke a new argument $4 if either is discovered.
11581 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
11582 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
11584 2001-09-28 Akim Demaille <akim@epita.fr>

11649 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
11650 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
11651 builddir, buildpath, top_builddir, and top_buildpath.

11723 * tests/Makefile.am (package.m4): Remove.
11725 2001-09-22 Akim Demaille <akim@epita.fr>
11727 Rely on `$LINENO' when possible instead of `__oline__'.
11729 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
11730 `$LINENO' support replacement when not supported.
11731 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
11732 them explicitly to be sure they are not output before this section

11741 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
11742 character (u: -> ue) in a code comment.
11743 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
11744 it works.
11746 2001-09-21 Akim Demaille <akim@epita.fr>
11748 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
11749 Suggested by Jim Meyering.
11751 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11753 * lib/autoconf/programs.m4: Use extensions listed in
11754 $ac_executable_extensions when looking for programs.

11766 PATH_SEPARATOR.
11767 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

11770 * lib/autotest/general.m4: Replace occurrences of ':' in

11773 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

11776 arguments. Fixed a typo.
11778 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11780 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
11781 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
11783 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11785 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
11786 * bin/autoupdate.in: Ditto.
11787 * bin/autoheader.in: Reworded a few comments.
11788 * bin/autoconf.in: Reworded help text for a few options.

11792 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11794 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
11795 already have $file). Set output files to binary mode (helps avoid
11796 CR issues on DOSish systems).
11798 2001-09-19 Akim Demaille <akim@epita.fr>
11800 * lib/autotest/general.m4: Englishoes.
11801 From Tim Van Holder and Alexey Mahotkin.
11803 2001-09-18 Paul Eggert <eggert@twinsun.com>
11805 * doc/autoconf.texi (Common Shell Constructs): New node,
11806 documenting AS_DIRNAME.
11807 (Limitations of Usual Tools): Refer to it when discussing dirname.
11808 Also, update discussion of POSIX standard to reflect latest draft.
11810 * lib/autoconf/c.m4:
11811 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
11813 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11814 Do not pass a first argument with leading '-'
11815 to expr, by parenthesizing initial integers that might be negative.
11817 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
11818 now merely checks whether it is an error to pass an argument
11819 to getpgrp.
11821 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
11822 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
11823 whether it is a (compile-time) error to pass an argument to
11824 getpgrp. This simpler test supports the revised documentation,
11825 and is all that AC_FUNC_GETPGRP's users really need.
11827 2001-09-18 Akim Demaille <akim@epita.fr>
11829 * doc/autoconf.texi (Limitations of Make) <$<>: New.
11831 2001-09-18 Akim Demaille <akim@epita.fr>

11839 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
11840 correctly.
11841 Add test for AS_BASENAME.
11842 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
11843 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11844 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11845 * tests/base.at: Fixed the expected responses. The old ones were
11846 one line out...
11847 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11848 the documentation claims it should (and how it behaved in 2.13).
11850 2001-09-18 Akim Demaille <akim@epita.fr>
11852 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
11853 the AC_CONFIG_COMMANDS invocation.
11854 This also solves the name clash problems.
11855 Don't set the package's ID.
11856 * lib/m4sugar/Makefile.am (version.m4): Revamp.
11857 No longer to be shipped.
11858 (version.in): Remove.
11859 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
11860 * lib/autoconf/status.m4: Adjust.
11861 Use `m4_PACKAGE_STRING'.
11862 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11863 the only optional argument is the name of the test suite.
11864 Expect `package.m4' to define the package signature.
11865 * lib/autom4te.in (Autotest): Add `package.m4?'.
11866 * tests/Makefile.am (package.m4): New.
11867 * tests/suite.at: ifnames is a victim.
11869 2001-09-18 Akim Demaille <akim@epita.fr>
11871 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
11872 AC_LIBSOURCE, AC_CONFIG_FILES.
11873 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
11874 program version string doesn't match the package's.
11875 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
11876 after `(cached)'.

11880 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11881 Allow expression to return any value that can fit into unsigned long
11882 (not int, as before). Check for output errors.
11884 2001-09-17 Bruno Haible <haible@ilog.fr>
11886 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11887 Always include <stdio.h> and <stdlib.h>. Evaluate
11888 the expression in an extra function before these includes. Call
11889 fprintf "%d" only after ensuring the argument is of type 'int'.
11890 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11892 2001-09-17 Paul Eggert <eggert@twinsun.com>
11894 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11895 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11896 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11897 when they don't exist.
11899 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11900 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11901 need it.
11903 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11904 version with the version used by fileutils 4.1, except use
11905 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
11906 we don't need it.
11908 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
11910 2001-09-13 Akim Demaille <akim@epita.fr>
11912 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
11913 _first_.
11914 Reported by Gerrit P. Haase.
11916 2001-09-13 Akim Demaille <akim@epita.fr>
11918 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

11931 (m4_re_escape): New.
11932 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER): Use it.
11933 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
11934 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
11935 Likewise.
11936 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
11937 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
11938 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
11939 AT_tests_all for consistency.
11940 Set at_victims.
11941 (AT_VICTIMS): Similar to AT_KEYWORDS.
11942 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
11944 2001-09-13 Akim Demaille <akim@epita.fr>
11946 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
11948 2001-09-13 Akim Demaille <akim@epita.fr>
11950 * lib/autotest/general.m4 (AT_INIT): Create and remove
11951 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
11952 test suites can cohabit.
11954 2001-09-13 Akim Demaille <akim@epita.fr>
11956 * tests/mktests.sh: Don't output banners for empty test files.
11958 2001-09-13 Akim Demaille <akim@epita.fr>
11960 Test suites can be run independently of configure.
11962 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.
11963 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.

11975 (Syntax of the shell scripts): Don't check ifnames.
11976 (AT_CHECK_PERL_SYNTAX): New.
11977 (Syntax of the Perl scripts): Check ifnames.
11978 * tests/ifnames: New.

11997 (_AT_CLEANUP_FILE_IF): Simplify the regexp.
11998 (AT_SETUP): Reset AT_line, AT_keywords, AT_description.
11999 No longer fill the HELP diversion.
12000 (AT_CLEANUP): Use them.
12001 * lib/m4sugar/m4sugar.m4 (m4_append): Support a separator.
12002 (m4_list_append): Remove.
12004 Spread a few keywords in the Autoconf test suite.
12006 2001-09-10 Akim Demaille <akim@epita.fr>
12008 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

12026 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
12027 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
12028 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
12029 related variables into `at_package_*'.
12030 * lib/autotest/general.m4 (AT_VICTIMS): New.
12031 (AT_INIT): Adjust for stand-alone/embedded test suites.
12032 (AS_MESSAGE_LOG_FD): Define and use it.
12033 * tests/suite.at (AT_VICTIMS): Use it.
12034 * tests/tools.at (autoupdating AC_PREREQ): Don't depend upon
12035 at_version.
12037 2001-09-07 Akim Demaille <akim@epita.fr>
12039 Move toward possibly stand-alone test suites.
12041 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
12042 in addition, it introduces useless differences in logs.
12043 (AT_INIT): Let atconfig and atlocal be both optional.
12044 Adjust PATH computation.
12045 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.
12047 2001-09-07 Akim Demaille <akim@epita.fr>
12049 * lib/autoconf/Makefile.am (autoconf.m4f): Depends upon

12052 2001-09-05 Akim Demaille <akim@epita.fr>
12054 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'

12056 From Uwe Seimet.
12058 2001-09-05 Akim Demaille <akim@epita.fr>
12060 * bin/autom4te.in: --language is -l, not -s.
12062 2001-09-05 Akim Demaille <akim@epita.fr>
12064 Be ready to handle filenames as stupid as `dnl.at', for if even
12065 the maintainer is dumb enough to do that...
12067 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
12068 excellence in M4 quotation: consider `__file__' is active.
12070 And BTW, when invoking m4, pass the --include in the right order:
12071 the wrong one.
12073 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
12074 4m.
12076 2001-09-05 Akim Demaille <akim@epita.fr>
12078 * lib/Autom4te/XFile.pm: New lib file.
12079 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
12080 * bin/autoheader.in: Use it.
12082 2001-09-05 Akim Demaille <akim@epita.fr>
12084 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff
12085 defined.
12087 2001-09-05 Akim Demaille <akim@epita.fr>

12093 Add -I, --include support.
12094 * doc/autoconf.texi (autoscan Invocation): Adjust.
12096 2001-09-05 Akim Demaille <akim@epita.fr>
12098 CVS GNU M4 doesn't like `undefine(undefined)'.
12100 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
12101 New, extracted from main.
12102 Use IO::File wherever possible.
12103 (input.m4): Be constant, use -I instead of hard coding $tmp.
12104 Therefore be a quoted heredoc.
12105 Don't invoke `_au_disable', since ac was not loaded, but just
12106 `unm4.m4'.
12108 2001-08-31 Akim Demaille <akim@epita.fr>
12110 Version 2.52d.
12112 2001-08-31 Akim Demaille <akim@epita.fr>
12114 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the
12115 previous patch.
12116 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Can create `config.hin~'.
12118 2001-08-31 Akim Demaille <akim@epita.fr>
12120 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
12121 serious problems handling heredocs in heredocs.
12122 Reported by Nicolas Joly.
12124 2001-08-31 Akim Demaille <akim@epita.fr>
12126 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
12127 (Making testsuite Scripts): Update.
12129 2001-08-31 Akim Demaille <akim@epita.fr>
12131 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
12133 2001-08-31 Akim Demaille <akim@epita.fr>
12135 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
12136 (testsuite Scripts): There is no such thing as `atconfig.in'.
12137 And actually one diagram is missing: test suite runtime.
12139 2001-08-31 Akim Demaille <akim@epita.fr>
12141 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
12142 inverse order.
12144 2001-08-31 Akim Demaille <akim@epita.fr>
12146 * bin/autoupdate.in (@include): `installcheck' revealed the path
12147 to m4sugar was lacking!
12149 2001-08-31 Akim Demaille <akim@epita.fr>
12151 * man/Makefile.am (.x.1): We really have to pass
12152 autom4te_perllibdir.
12154 2001-08-31 Akim Demaille <akim@epita.fr>
12156 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
12157 debug scripts, in particular passing explicitly listed tests to
12158 run is stupid.
12160 2001-08-31 Akim Demaille <akim@epita.fr>
12162 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
12163 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
12164 Use directly autom4te, not autoconf.
12165 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
12167 2001-08-31 Akim Demaille <akim@epita.fr>
12169 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
12170 * bin/autoheader.in (%symbol): Strip arguments of macros.

12176 2001-08-31 Akim Demaille <akim@epita.fr>
12178 * bin/autom4te.in (&parse_args): Die on unknown languages.
12179 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
12180 need for autoconf.
12181 Promote --include over --macrodir and other obsolete options.
12183 2001-08-31 Akim Demaille <akim@epita.fr>
12185 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
12186 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
12187 * bin/autom4te.in ($autoconf): Pass --force.
12188 `print $out' doesn't print `$_' but `$out'.
12189 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
12190 (autoheader): Pass --force since the test suite goes too fast for
12191 the time stamps.
12192 Adjust to the new autoheader messages.
12194 2001-08-31 Akim Demaille <akim@epita.fr>
12196 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
12197 Check the completeness of the #template.
12198 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
12199 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
12200 invocation.
12202 2001-08-31 Akim Demaille <akim@epita.fr>
12204 * lib/Autom4te/General.pm (&find_file, &update_file): New.
12205 * bin/autoupdate.in, bin/autoheader.in: Adjust.
12206 Drop AC_MACRODIR dead for real.
12207 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
12208 `autoheader: `config.hin' is created'.
12209 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
12211 2001-08-31 Akim Demaille <akim@epita.fr>
12213 * bin/autoheader.in: Rewrite in Perl.
12214 * tests/autoheader: Adjust.
12216 2001-08-31 Akim Demaille <akim@epita.fr>
12218 * bin/autoconf.in (--include, -I): New option.
12219 Map --localdir, --autoconf-dir onto it.
12220 Forward autom4te's options instead of interpreting them.
12221 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
12222 There is no such envvar since the inception of autom4te.cfg.
12223 * bin/autom4te.in (&parse_args): Uniquify `@include'.
12224 * bin/autoupdate.in: Adjust, and perform more control.
12225 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
12226 * tests/autoconf: Dittowise.
12228 2001-08-31 Akim Demaille <akim@epita.fr>
12230 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
12231 * bin/autom4te.in (&find_file): Support `FILE?' standing for
12232 optionally `FILE'.
12233 Use -e, not -f, since /dev/null for instance is OK.
12234 (&parse_args): Adjust.
12235 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
12237 2001-08-31 Akim Demaille <akim@epita.fr>
12239 * configure.ac: Also find tested executables in bin.
12240 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
12241 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
12242 installed peer executables, only PATH is allowed to resolve it.
12243 Pass `autoconf_dir' via options, not via invisible envvars.
12244 * lib/Autom4te/General.pm (&find_peer): Remove.
12245 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
12246 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
12247 * man/Makefile.am: Let help2man rely on PATH instead of trying to
12248 find the executables for it.
12249 * tests/Makefile.am: Major cleanup. Too lazy to document...
12250 * tests/atlocal.in: Remove all the obscure envvar manipulations.
12251 We only need PERL.
12252 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
12253 indeed related to running the test suite, while passing
12254 --autoconf-dir and others is related to running non installed
12255 Autoconf executables. So don't do that, leave it to...
12256 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
12257 * tests/autoscan: New.
12258 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
12259 refer to library files: rely on --language.
12261 2001-08-29 Akim Demaille <akim@epita.fr>
12263 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
12264 s/--set/--language/.
12266 2001-08-29 Akim Demaille <akim@epita.fr>
12268 * doc/autoconf.texi: Strip the @nodes.
12269 Suggested by Paul Eggert.
12270 (Initializing configure): Typo.
12272 2001-08-29 Akim Demaille <akim@epita.fr>
12274 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
12275 Suggested by Paul Eggert.
12277 2001-08-29 Akim Demaille <akim@epita.fr>
12279 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
12280 download in a tmp dir.
12282 2001-08-29 Akim Demaille <akim@epita.fr>
12284 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
12285 case insensitive OSes out there :(
12286 From Tim Van Holder.
12288 2001-08-29 Akim Demaille <akim@epita.fr>
12290 * lib/autom4te.in: New.
12291 * lib/Makefile.am (edit, autom4te.cfg): New.
12292 * bin/autom4te.in (BEGIN): Simplify.
12293 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
12294 (&load_configuration): New. Use it.
12295 (&parse_args): Support --mode, --set, and --melt.
12296 * bin/autoconf.in: Simplify and adjust.
12297 * tests/Makefile.am (AUTOMAKE): Use --set.
12298 * tests/atlocal.in: Adjust.
12299 * BUGS: distcheck and check are weak.
12301 2001-08-29 Akim Demaille <akim@epita.fr>
12303 * lib/autotest/general.m4: Use
12304 foo=`(command) 2>/dev/null`
12305 not
12306 foo=`command` 2>/dev/null
12307 (at-devnull): Rename as...
12308 (AT-devnull): this.
12309 (--clean): Remove AT-* files too.
12310 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
12311 Reported by Nicolas Joly.
12313 2001-08-28 Akim Demaille <akim@epita.fr>
12315 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
12316 quotes inside single quotes.
12317 Reported by Nicolas Joly.
12319 2001-08-28 Kevin Ryde <user42@zip.com.au>
12321 * doc/autoconf.texi (Function Portability): Mention C right shifts.
12323 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
12325 * lib/autotest/general.m4: Reword some messages.
12326 (AT_INIT): Check for the `times' builtin before using it.
12327 Support test ranges as arguments to the testsuite.
12328 Have -e imply -d as the help text suggested.
12330 2001-08-27 Akim Demaille <akim@epita.fr>
12332 * Makefile.maint: Formatting changes.
12333 (do-po-update, po-update, cvs-update, update): New targets.
12334 (AMTAR): Remove.
12336 2001-08-27 Akim Demaille <akim@epita.fr>
12338 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

12343 2001-08-27 Akim Demaille <akim@epita.fr>
12345 * lib/autotest/general.m4 (AT_INIT): Log the command line.
12346 Support `VAR=VAL' as arguments.
12347 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
12348 may be set via the command line.
12350 2001-08-27 Akim Demaille <akim@epita.fr>
12352 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
12353 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
12354 first the build dirs, then the src dirs.
12355 * configure.ac (AC_CONFIG_TESTDIR): Adjust.
12357 2001-08-27 Akim Demaille <akim@epita.fr>

12364 2001-08-27 Akim Demaille <akim@epita.fr>
12366 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
12367 `ac_top_builddir' to mimic Automake's vocabulary, which much more
12368 readable.
12369 Adjust callers.
12370 * doc/autoconf.texi (Configuration Actions): Document the vars
12371 available in commands.
12372 Emphasize the risks of collisions in init-cmds.

12376 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
12377 (Initializing configure): this new node.
12379 2001-08-27 Akim Demaille <akim@epita.fr>

12392 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move
12393 to...
12394 * lib/autoconf/autoheader.m4: this new file.
12395 * lib/autoconf/general.m4 (AH_OUTPUT, AH_VERBATIM)

12402 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
12403 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
12404 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
12405 -> ac_dir).
12406 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
12407 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
12409 2001-08-27 Akim Demaille <akim@epita.fr>
12411 * lib/autoconf/autoconf.m4 (AC_CONFIG_COMMANDS)

12434 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
12435 (AMTAR): Help automake define it.
12436 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
12437 needed, 1.5 can have a macro and a target with the same name.
12438 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
12439 * m4/strip.m4: New.

12452 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
12453 Adjust callers.
12454 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
12455 the name of the directory they're in, instead of the filename,
12456 since version.m4 is now in m4sugar, but m4_acversion must not be
12457 classified as an Autoconf macro.
12458 ($input_m4): Don't qualify the path to m4sugar.
12459 Rather, pass autoconf_dir to m4.
12460 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
12461 * tests/suite.at: Require 2.52c.
12463 2001-08-27 Akim Demaille <akim@epita.fr>

12544 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
12545 * NEWS, README, README-alpha, TODO, tests/README: This package is
12546 `Autoconf', not `autoconf' (the executable).
12548 2001-08-20 Akim Demaille <akim@epita.fr>
12550 Info readers seem to need `Index' in the index node title :(
12552 * doc/autoconf.texi: Reverse the 2001-08-15 change which
12553 simplified index node names.

12597 2001-08-20 Akim Demaille <akim@epita.fr>
12599 Huh!?!?! There are still some user EOF tags used, which prevents
12600 their use in AC_CONFIG_COMMANDS for instance...
12602 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
12603 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

12666 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
12667 `$0.log' as for projects where testsuite is in src, we'd have

12682 2001-08-17 Akim Demaille <akim@epita.fr>
12684 * doc/autoconf.texi: Work around Texinfo buglets.
12685 (Transformation Rules): One example is enough, users are expected
12686 to have their brains on. And BTW, use DESTDIR.
12687 (dvar): New macro. Use it.
12689 2001-08-17 Akim Demaille <akim@epita.fr>
12691 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

12731 value.
12732 From Kevin Ryde.
12734 2001-08-15 Akim Demaille <akim@epita.fr>
12736 * Makefile.maint (CVS): New.
12737 (local-check): Run changelog-check. last.
12738 (alpha): Don't depend upon local-check, since...
12739 (cvs-dist): depends upon it.
12741 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
12743 * tests/Makefile.am: Use a clean-local rule to remove
12744 autom4te.cache (it's a directory, not a file.
12745 * Makefile.am: Ditto (but maintainer-clean-local).
12747 2001-08-15 Akim Demaille <akim@epita.fr>
12749 * bin/autom4te.in (@m4_warning): New.
12750 (&handle_m4): Use it.
12751 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
12752 warnings are issued at each run.
12753 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
12754 is in the src tree.
12756 2001-08-15 Akim Demaille <akim@epita.fr>
12758 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
12759 don't waste time running `autoupdate --version' works.
12760 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
12762 2001-08-13 Akim Demaille <akim@epita.fr>
12764 * doc/autoconf.texi (ma): Rename this index as...
12765 (ac): this.

12787 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
12788 to the INSTALL file.

12815 * tests/mktests.sh: Update year in copyright notice.
12817 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
12819 * tests/semantics.at (AC_C_BIGENDIAN): New test.
12821 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12823 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
12824 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
12825 * doc/autoconf.texi (C Compiler Characteristics): Update
12826 documentation for AC_C_BIGENDIAN.
12828 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12830 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
12831 magic values from an object file when cross-compiling.
12832 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12834 2001-08-10 Akim Demaille <akim@epita.fr>
12836 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12837 effects.
12838 Suggested by Russ Allbery.
12840 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12842 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12843 current $prefix to the sub-configures.
12845 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12847 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12848 extension (needed on BeOS). Reported by Guido van Rossum.
12850 2001-08-09 Akim Demaille <akim@epita.fr>
12852 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12854 2001-08-07 Akim Demaille <akim@epita.fr>
12856 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12857 removed.
12858 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12859 No need to remove the files before and after the each test, before
12860 each test and at the end of the suite is enough.
12861 Display only the children `times', not the shell's.
12862 If the test failed or was skipped, at-times is not available.
12864 2001-08-07 Akim Demaille <akim@epita.fr>
12866 Always produce testsuite.log, including when there are no
12867 failures. This helps getting information on skipped tests, and
12868 duration of the tests. Err, implement the latter btw.
12870 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12871 Dump information on the first run of each test.
12872 (AT_CLEANUP): Create `at-times' containing the duration of the
12873 test group.
12875 2001-08-07 Akim Demaille <akim@epita.fr>
12877 The use of `dumpstat' revealed that `len' was used although it
12878 should not. m4_text_wrap was using it, but in the Autoconf world
12879 where it is legal. Hence (i) test M4sh in its own world, not
12880 Autoconf's, and (ii), ahem, fix the bug :)
12882 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12883 does not like `' instead of [].
12884 (AT_INIT): Forbid `^_?AT_'.
12885 And don't output such tokens.
12886 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12887 `script.as', and `autom4te.cache'.
12888 Remove `empty' and `macro' which are no longer used.
12889 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12890 * tests/m4sugar.at: Use it.
12891 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
12893 2001-08-07 Akim Demaille <akim@epita.fr>
12895 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
12897 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
12899 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
12901 2001-08-04 Akim Demaille <akim@epita.fr>
12903 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
12904 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
12905 AC_TRY_LINK.
12906 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
12907 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
12908 (AC_F77_MAIN): Likewise.
12910 2001-08-04 Akim Demaille <akim@epita.fr>
12912 Don't rely on M4sugar outputting the patterns in files, since we
12913 might process the output _without_ running m4, hence without these
12914 files.
12916 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12917 * bin/autom4te.in (@Request::includes): Remove, unused.
12918 (@Request::source): Rename as...
12919 (@Request::input): this.
12920 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
12921 (&handle_output): Fetch the patterns from the traces.
