932 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
933 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
934 works but the latter doesn't, then it's a valid type.
935 This lets people use function types and so forth.
936 For C++ there doesn't seem to be a simple solution, so leave it alone.
937 (AC_CHECK_SIZEOF): Allow argument to be a variable.
938 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

997 (Limitations of Usual Tools): Also list \< and \>, and mention that
998 HP-UX's grep, like the one from Solaris, does not support that syntax.
1000 2007-03-09 Stepan Kasal <kasal@ucw.cz>
1002 * doc/autoconf.texi (Specifying Names): `--host' does not

1008 suggests AC_CONFIG_HEADERS.
1009 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Warn if not using
1010 AC_CONFIG_HEADERS. Problem reported by
1011 Peter O'Gorman.

1018 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
1019 universal binaries. Problem reported by Elias Pipping.
1021 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
1023 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.

1027 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
1028 Reindent for sanity's sake.
1030 2007-02-24 Eric Blake <ebb9@byu.net>
1032 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update
1033 copyright.
1034 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
1035 * lib/autotest/general.m4 (AT_INIT): Likewise.
1036 (_AT_DECIDE_TRACEABLE): Fix syntax highlighting.
1038 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1040 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
1041 status of rm so we know when it failed.
1042 If cleaning of test dir failed before running the test, warn.
1043 Output the line separator in verbose mode before the warning
1044 to make clear the warning belongs to the following test.
1046 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
1048 * doc/autoconf.texi (Parentheses): Mention problem with (( in
1049 shells.

1055 errors introduced in last change.
1057 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
1059 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to
1060 an actual carriage return. Use "ac_cr" to contain the actual
1061 carriage return.
1062 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
1063 with traditional Awk and begin.
1064 * tests/torture.at (Limitations of Builtins): Document the problem
1065 with Bash 2.03 printf.
1066 (Substitute and define special characters):
1067 Remove trailing white space. Work around a bug in Solaris 8 /bin/bash.
1069 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
1071 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
1072 input from /dev/null in awk test, so even Solaris /usr/bin/awk
1073 will not wait for input with a script containing only a BEGIN
1074 rule.
1076 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
1078 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version

1098 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
1100 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
1101 latest version.
1102 (Shell Substitutions): Note problems with @{var:=value} etc.
1103 Add a new section for problems with @{#var} etc. Problem noted
1104 by Ralf Wildenhues. See:

1107 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1109 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
1110 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
1111 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
1112 substitution will still be done by the special code.
1113 Report by Jim Meyering.
1115 * doc/autoconf.texi (File System Conventions): Mention that
1116 $PATH_SEPARATOR is for the build system only.

1127 Test all 8 bit non-NUL characters.
1128 Report against Automake by Patrick Welche.
1130 2007-01-15 Stepan Kasal <kasal@ucw.cz>
1132 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
1134 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1136 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
1137 early on the reader side, drop stderr of the input to avoid
1138 `broken pipe' error output; this may happen even with shell
1139 builtin `echo' of some bash versions. Reports by Ian Macdonald
1140 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
1142 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1144 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
1145 separate items of `ac_user_opts', to avoid long lines.
1146 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
1148 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1150 * doc/autoconf.texi: Fix some typos.
1152 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
1154 Fix some wording problems noted by Paolo Bonzini in:
1155 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
1156 * doc/autoconf.texi (Signed Overflow Examples): Give more
1157 discussion about the allow_superuser_privileges example,
1158 and change it a bit to make things clearer.
1159 (Optimization and Wraparound): Clarify whether the compiler
1160 will generate an infinite loop for the example derived from
1161 Autoconf's mktime test.
1162 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
1163 Also, clarify unsigned multiplication overflow.
1165 2007-01-04 Eric Blake <ebb9@byu.net>
1167 * bin/Makefile.am (RELEASE_YEAR): New macro.
1168 (edit): Use it to supply correct copyright year to scripts.
1169 * bin/autoconf.as (version): Use it.
1170 * bin/autoheader.in ($version): Likewise.
1171 * bin/autom4te.in ($version): Likewise.
1172 * bin/autoreconf.in ($version): Likewise.
1173 * bin/autoscan.in ($version): Likewise.
1174 * bin/autoupdate.in ($version): Likewise.
1175 * bin/ifnames.in ($version): Likewise.
1177 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
1179 * doc/autoconf.texi (Integer Overflow): Revised based on today's
1180 feedback. The most important changes document what happens when
1181 you convert an out-of-range value to a signed integer type, and
1182 say that (sum < a) != (b < 0) reliably detects overflow when sum =
1183 a + b.
1185 * doc/autoconf.texi (Integer Overflow): Greatly expand and
1186 rewrite, taking notions from the recent discussion on the gcc and
1187 autoconf mailing lists; please see
1188 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
1189 and follow the many links.
1190 (Integer Overflow Basics, Signed Overflow Examples):
1191 (Optimization and Wraparound, Signed Overflow Advice):
1192 (Signed Integer Division): New sections.
1194 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
1196 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
1197 preprocessor macro arguments in traced name.
1198 * doc/autoconf.texi (Defining symbols): Document longstanding
1199 support for AC_DEFINE-ing macros with arguments, and document
1200 behavior when the same variable has multiple AC_DEFINEs.
1201 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
1202 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
1203 macros directly, giving much shorter and simpler code.
1205 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
1207 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
1208 space before "$ac_configure_args" to prevent a 'config.status
1209 --recheck' failure if ac_configure_args doesn't contain a leading
1210 space. This works around a problem with the XEmacs configure.ac,
1211 which uses the (undocumented) ac_configure_args variable
1212 inconsistently with Autoconf.
1214 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
1216 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
1217 Include <limits.h>, and use its INT_MAX to rewrite the
1218 j loop so that it does not overflow 'int'. Problem reported by
1219 Ralf Wildenhues in
1220 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
1221 Play it safe by shifting left by 1 rather than multiplying by 2,
1222 as GCC is less likely to optimize this away when the value
1223 is signed (when it assumes overflow leads to undefined behavior).
1224 Also, don't assume time_t uses two's complement.
1226 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1228 * tests/torture.at (Substitute a 2000-byte string): Avoid using
1229 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
1230 dumps core on it. Report by Tim Rice.
1232 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1234 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
1235 --disable-option-checking to --help output even when
1236 AC_PRESERVE_HELP_ORDER is not used.
1237 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
1238 --with argument, rather than argument with [-.] replaced by
1239 underscores.
1240 * NEWS: Fix typo in previous change; the news was in the
1241 wrong section.
1243 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
1245 * NEWS: Warnings are now generated by default for unknown
1246 --enable-* and --with-* options.
1247 * doc/autoconf.texi (Option Checking): Renamed from
1248 (Configure Option Checking). Tighten up the wording a bit.
1249 (External Software, Package Options): Cross-reference to Option
1250 Checking, and use this to shorten our section.
1251 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
1252 "$x" to test "x$foo" != x.
1253 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
1254 Don't warn if $enable_option_checking is "no".
1255 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
1256 ac_unrecognized_opts to the empty string.
1257 Don't echo the unrecognized opts, as this might mishandle
1258 backslashes or leading -.
1259 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
1260 usage next to the other --disable-FEATURE options in the
1261 help string.
1263 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1265 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
1266 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
1267 Print warning for unrecognized --with and --enable options
1268 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
1269 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
1270 Disable option checking when subdirs are configured.
1271 (AC_OUTPUT): If warnings are enabled, print warning about
1272 unrecognized --with and --enable options at the end of
1273 the configure output (as well as at the beginning).
1274 * doc/autoconf.texi (Option Checking): New node.
1275 Document new option warning functionality.
1277 2006-12-16 Eric Blake <ebb9@byu.net>
1279 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
1280 * NEWS: Start news for current version.
1282 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
1284 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1285 Define HAVE_GETMNTENT to 1, not to the empty string.
1286 Problem originally reported by Jochen Friedrich in
1287 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
1289 This change prompted by a problem report by Andrey Simonenko in
1290 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
1291 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
1292 object-like macros only, in the traditional portable character
1293 set.
1294 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
1295 Warn about attempts to define things that are not identifiers.
1296 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
1297 awful hack that AC_DEFINEd macro names containing parentheses.
1299 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
1301 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
1302 too drastic, even if Texinfo in theory requires it for info mode.
1304 (config.status Invocation): Renamed back from Recreating a
1305 Configuration).
1306 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
1307 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
1309 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1311 * NEWS: Version 2.61a.
1313 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1314 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1316 * NEWS: Document changes with echo and printf, and the lack
1317 of limits on the total size of multi-line values of substituted
1318 variables, and the AC_FUNC_FSEEKO fix.
1320 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
1322 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
1323 Writing configure.ac.
1324 (Autoconf Input Layout): Renamed from configure.ac Layout.
1325 (Recreating a Configuration): Renamed from config.status Invocation.
1326 (Obsolete Recreation): Renamed from Obsolete config.status Use.
1327 (acconfig Header): Renamed from acconfig.h.
1328 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
1329 (Writing Testsuites): Renamed from Writing testsuite.at.
1330 (Autom4te Cache): Renamed from autom4te.cache.
1332 * BUGS: Remove mention of VPATH problem, since it's now documented
1333 not to be a bug in the Autoconf build procedure itself, but rather
1334 a problem with the proprietary `make' programs.
1336 * doc/autoconf.texi (Build Directories): Add a cross reference
1337 to VPATH and Make.
1339 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
1340 * doc/standards.texi: Sync from gnulib.
1342 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
1343 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
1344 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
1345 generated automatically.
1347 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
1349 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
1350 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
1351 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
1353 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1355 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
1356 `CEOF$ac_eof' special marker, the awk script cannot contain a
1357 line matching `^CEOF', so this is not needed any more.
1358 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
1359 special marker in the test.
1361 2006-12-06 Stepan Kasal <kasal@ucw.cz>
1363 * tests/tools.at (autom4te preselections): Use `find -newer';
1364 remove one of the sleeps.
1366 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
1367 more readable, using ...
1368 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
1370 * doc/autoconf.texi (autoheader Invocation): Do not double-
1371 quote the parameter of `AH_BOTTOM' in the example.
1373 2006-12-05 Stepan Kasal <kasal@ucw.cz>
1375 * doc/autoconf.texi (Configuration Headers): Remove the
1376 example with multiple input files.
1377 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
1378 multiple input files.
1380 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1382 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
1383 creating the awk substitution script, handle one input line at a
1384 time, so that the maximum length of a substituted (multi-line)
1385 value is not limited by the size of the sed pattern space.
1386 The trade-off is a slightly repetitive sed script.
1387 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
1388 can only have up to 7 characters, due to Solaris 10 /bin/sed.
1389 * tests/torture.at (Substitute a 2000-byte string): Increase the
1390 test with several long lines, they should not be caught by sed
1391 limits any more.
1393 * tests/tools.at (autom4te preselections): New test, to flag
1394 entries missing from autom4te.cfg.
1395 Report by David Byron <dbyron@hheld.com>.
1397 * tests/torture.at (Substitute a 2000-byte string): Actually use
1398 AC_PROG_AWK, so the last change works as intended.
1399 (Substitute and define special characters): Likewise.
1400 (Substitute a newline): Likewise.
1402 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
1403 instead of `awk' consistently.
1404 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
1405 * tests/torture.at (Torturing config.status): Test both the
1406 result of AC_PROG_AWK and plain awk.
1407 (Substitute a 2000-byte string): Likewise.
1408 (Substitute and define special characters): Likewise.
1409 (Substitute a newline): Likewise.
1411 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
1413 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
1414 can be assigned to a function pointer. Problem reported by
1415 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
1416 part of a patch by Ralf Wildenhues in that same bug report.
1418 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
1420 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
1421 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
1423 2006-12-01 Eric Blake <ebb9@byu.net>
1425 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
1426 cross-compiling from cygwin to mingw.
1427 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
1428 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
1429 to lib/autoconf/c.m4.
1431 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1433 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
1434 string for more reliable failure. Wrap the entire test that
1435 causes the broken Solaris printf to dump core, in a subshell,
1436 so the segmentation fault message is reliably suppressed.
1437 Fix shell expansion errors by using /usr/ucb/echo always;
1438 avoid an error on systems without it by another subshell.
1439 Avoid m4 expansion of `$1'. Set the zeroth argument of the
1440 subshell-$as_echo to `as_echo', for better error message.
1442 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1444 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
1445 `BASH_SOURCE' contain a newline, set them to empty, as they may
1446 not be unset.
1448 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
1450 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
1451 years and is too hard to maintain now. The last straw was
1452 reported by Jerker Baeck in
1453 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
1454 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
1455 * doc/autoconf.texi (Particular Functions): Move
1456 AC_FUNC_SETVBUF_REVERSED from here...
1457 (Obsolete Macros): ... to here. Say that it does nothing now.
1458 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
1459 Turn into (almost) a no-op.
1461 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
1462 (AC_C_VOLATILE):
1463 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
1464 These macros are obsolescent and new applications shouldn't need them.

1475 @VAR1@VAR2 has unspecified behavior. Problem reported by
1476 Ralf Wildenhues.
1477 * NEWS: Mention this.
1479 * Makefile.am: Put only a single '#' into the copyright notice,
1480 so that it's also present in the output file. Standardize wording
1481 in makefile copyright notices to match GNU coding standards.

1495 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1497 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
1498 in the sed script that mangles the awk script: delete up to the
1499 first exclamation mark only.
1500 * tests/torture.at (Substitute and define special characters):
1501 Test '!' too.
1503 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1505 Rewrite config files generation: avoid quadratic growth in
1506 the number of substituted variables by using awk instead of sed
1507 for the bulk of the substitutions.
1508 * NEWS: Mention this.
1509 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
1510 forbidden in the output (and thus input) file.
1511 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
1512 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
1513 generate just one large awk script for substitutions,
1514 eliminating much of the earlier complexity, while adding some
1515 new complexity. Only expand the substitution templates at
1516 configure time, for smaller configure script size. If
1517 _AC_SUBST_FILES are used, test 'awk' for working getline support
1518 at config.status time. If absent, interpolate through the
1519 shell. The awk script was written with much help
1520 from Paolo Bonzini and Paul Eggert.

1526 * tests/torture.at (Substitute a 2000-byte string): Also
1527 substitute a line with 1000 words, and a variable with several
1528 long lines.
1529 (Substitute and define special characters): Test awk special
1530 characters, and put substitution input strings `@foo@' in the
1531 output, to test that no recursion happens; test several other
1532 combinations from Paolo Bonzini.
1534 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
1536 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
1537 that replaced echo with AS_ECHO where this wasn't necessary.
1538 Problem reportd by Ralf Wildenhues.
1539 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
1540 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
1541 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
1543 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1545 * lib/freeze.mk (GREP): Removed, no need to initialize this.
1547 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
1549 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
1550 that traditional Awk lacks 3-arg "split". It has it.
1551 Mention that FS must be a single character, and a few other
1552 99-byte limits of traditional Awk.
1553 Mention that if (i in a) doesn't work with traditional Awk.

1559 (Newline-CODE-BS-newline in command):
1560 (Single-quote-BS-newline in command):
1561 (Single-quote-newline-BS-newline in command):
1562 Use printf '%s\n' instead of echo, for portability to hosts
1563 where echo interprets backslashes. This will break on hosts
1564 that lack printf, but for now let's assume all such hosts
1565 are dead (if not, we should get reports of test failures).
1567 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
1569 'echo' has some portability problems, when given a first argument
1570 with a leading '-', or when given any argument containing '\'.
1571 Avoid using 'echo' in these cases.

1599 * lib/autotest/general.m4 (AT_INIT): Likewise.
1600 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
1601 Don't use ECHO_T, since ECHO_N is now reliable.
1602 * lib/autotest/general.m4 (AT_INIT): Likewise.
1603 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
1604 rather than using a here-document to put the script into a file.
1605 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
1606 use AS_ECHO.
1607 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
1608 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
1609 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any

1613 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

1615 operand, as AS_ECHO requires. Avoid double file name expansion.
1616 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
1617 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
1618 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
1619 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
1620 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
1621 Double-quote strings that would otherwise contain M4 comments.
1622 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
1624 * configure.ac (AC_INIT): Bump to 2.61a.

1632 * NEWS: Likewise.
1634 * tests/autotest.at (Macro with backslash in a test title):

1750 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
1751 and Stepan Kasal <kasal@ucw.cz>
1753 Handle special characters in test case titles correctly.

1761 Single-quote in a test title,
1762 Double-quote in a test title): Don't expect failure anymore.
1763 (Backslash in a test title): Put a non-whitespace character after the
1764 backslash so that Bourne shells might actually see it as an escape
1765 sequence.
1766 (Brackets in a test title,
1767 Pound in a test title,

1787 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
1788 5363) simply issues a warning when dividing by zero at compile
1789 time. Problem reported by Elias Pipping.
1791 2006-10-26 Eric Blake <ebb9@byu.net>

1825 reported by Nelson H. F. Beebe for Coreutils 6.4.
1827 * tests/tools.at (autoconf --trace: user macros): Remove test

1833 * bin/autom4te.in (handle_m4): Do not redirect stdin to
1834 /dev/null since the heuristics for interactive behaviour was
1835 fixed in CVS m4.

1910 directory. In some cases the unpatched install-sh could do the
1911 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
1912 system. We hope this is rare in practice, but it's clearly worth
1913 fixing. Problem reported by Alex Unleashed in
1914 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
1915 Also, don't bother to check for -m bugs unless we're using -m;
1916 suggested by Stepan Kasal.

1965 added to the template can get mangled.
1967 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1969 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
1970 include the default headers, and redefine obstack_chunk_alloc

1985 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
1987 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
1988 the NonStop platform.
1989 * doc/autoconf.texi (Posix Variants): Likewise.
1990 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
1992 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
1993 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
1994 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
1995 Use a better substitute, by inspecting the output of "ls"
1996 rather than just using ":".
1997 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
1998 rather than AS_EXECUTABLE_P, since we needn't worry about
1999 non-regular files here.
2001 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
2002 due to configuration hassles with this. See Tonya Underwood's report
2003 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
2004 * doc/autoconf.texi (Special Shell Variables): Likewise.
2006 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
2007 Stepan Kasal <kasal@ucw.cz>
2009 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
2010 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
2012 2006-10-11 Stepan Kasal <kasal@ucw.cz>
2014 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
2015 initialization which is not inherited through the environment
2016 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
2017 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
2019 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
2021 * doc/autoconf.texi (Limitations of Usual Tools): Describe
2022 problems with mkdir -p -m.
2024 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
2026 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
2027 comment about ac_cpp_err; it was incorrect, and anyway
2028 ac_cpp_err is being removed below.
2029 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
2030 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
2031 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
2032 nobody uses it.
2033 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
2034 with werror_flag and conftest.err and so forth. This is more
2035 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
2036 and anyway the user shouldn't normally want to see this gorp logged.
2037 Problem reported by Ralf Wildenhues.
2038 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
2039 empty, not 'no', since the rest of the code uses 'test -z'.
2041 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
2043 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2044 Use a single call to AC_DO_TOKENS rather than multiple, for
2045 efficiency.
2046 (_AC_LINK_IFELSE): Test that resulting file is executable.
2047 Problem reported by mwoehlke in
2048 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
2050 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
2051 than creating a file to use with test -x; this is much faster.
2053 2006-10-02 Bruno Haible <bruno@clisp.org>
2055 * lib/autom4te.in (Automake-preselections): Add
2056 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
2058 2006-09-27 Stepan Kasal <kasal@ucw.cz>
2060 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
2061 standard error, `experr' should be used, not `expout'.
2063 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
2065 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
2066 fseeko testing program twice; just use the earlier result.
2067 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2068 Set cache var to 'unknown' (not 'no') if leaving the macro unset
2069 still doesn't let the program compile.
2070 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
2071 failed.
2073 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
2074 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
2075 include it, without including anything else.
2076 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
2077 expressions.
2078 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
2080 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2082 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
2083 `error.h', and include it, for a `error_at_line' prototype.
2084 Use a nonempty format string in the link test.
2085 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
2086 for a declaration of wait3.
2088 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
2090 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
2091 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
2092 can apply to constants too, and that it checks for macro defns.
2093 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
2094 and simply cast the identifier to void. This handles structure
2095 values. Problem reported by Ralf Wildenhues.
2096 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
2098 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2152 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
2153 --error-output, to avoid warnings with M4 2.0.
2155 2006-09-19 Stepan Kasal <kasal@ucw.cz>
2157 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be

2168 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
2169 mistaken comment: the path has to be relative; do not use
2170 the path at runtime.
2172 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2174 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

2184 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
2185 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
2186 for the existence of the directory at configure-time. That's
2187 too late, anyway. Problem reported by Stefan Seefeld.
2189 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
2190 7.1.4 /usr/bin/posix/sh described by Tim Rice in
2191 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
2193 2006-09-11 Stepan Kasal <kasal@ucw.cz>
2195 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
2196 works with GNU M4 1.4.3 again; make the normalized form
2197 match the current m4 message; fix the description.
2198 * test/tools.at (autom4te cache): Adapt to the change.
2200 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
2202 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
2203 to catch glibc bug 2821
2204 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
2206 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
2207 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
2208 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
2209 assume C89.
2211 2006-09-08 Stepan Kasal <kasal@ucw.cz>
2213 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the

2231 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
2232 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
2233 accept files with extension `.f'. For consistency, also prefer
2234 xlf over f77.
2235 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
2236 from last patch.

2257 except the first two arguments are reversed.
2258 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
2259 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
2260 caches nor outputs a diagnostic. Suggested by Bruno Haible.
2261 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
2262 equivalent to the old AC_COMPUTE_INT.
2263 (AC_COMPUTE_INT): No longer caches or reports. New signature.
2264 All uses changed to AC_CACHE_CHECK_INT.
2265 * tests/base.at (AC_CACHE_CHECK_INT): New test.
2266 * tests/mktests.sh (ac_exclude_list): Add AC_CACHE_CHECK_INT.
2268 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
2270 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
2271 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
2272 programs should use their Gnulib counterparts.
2273 * doc/autoconf.texi (Particular Functions): Likewise.
2274 (Macro Names, testsuite Invocation): Replace uses of these
2275 obsolete macros with uses of non-obsolete macros.

2303 Fix Lex library problem reported to us by Julio Garvia.
2304 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
2305 for the default, which the user can override.
2306 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
2307 deal with LEXLIB.
2308 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
2309 didn't work if some values were cached but not others. Test for
2310 broken lex libraries like native ia64-hp-hpux11.22; see
2311 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
2312 work around the problem by preferring an empty LEXLIB to -lfl or
2313 -ll. Let the user set LEXLIB='' to indicate no library needed.
2315 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
2316 * README: Likewise.

2412 * lib/autoconf/c.m4 (_AC_PROG_CC_C99): Test varargs macros and
2413 64-bit preprocessor ints. Check for static initialization of
2414 long long. Remove unnecessary casts.
2416 2006-08-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2418 * doc/autoconf.texi (Particular Programs): Mention that
2419 @INSTALL@ and @MKDIR_P@ may vary for different output files.
2420 Reported by Alexandre Duret-Lutz.
2422 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
2424 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
2425 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
2426 Bill Northcott in
2427 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.

2431 * lib/autoconf/c.m4 (AC_C_CONST): Don't used shadowed vars, to
2432 pacify insanely picky compilers. Problem reported by Eric Blake.
2434 * doc/autoconf.texi (Posix Variants): INTERACTIVE Unix is no
2435 longer supported by Sun.
2437 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
2439 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
2440 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
2441 -Wundef -Werror". Problem reported by David Fang in
2442 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

2458 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
2459 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
2460 this.
2462 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
2464 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
2465 problems with arg script text that doesn't end in newline, and
2466 with '-e a...'. Problems reported by Ralf Wildenhues.
2468 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
2470 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
2471 check for libXt by a check for libX11.
2473 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2475 * doc/autoconf.texi (config.status Invocation): Adjust according
2476 to last change.
2478 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2480 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
2481 --help' should mention that `--version' outputs configuration
2482 settings. Report by Bruno Haible.
2484 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
2486 Fix test suite failures reported by Pierre in
2487 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
2488 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
2489 the compiler created a file "b.out" when it didn't create anything
2490 at all.

2492 Discard stderr too, when invoking the test script.
2494 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
2496 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
2497 in the restoring of the werror flag.
2499 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>

2502 less skeptical about "volatile", after discussion with
2503 Bruno Haible on bug-gnulib.
2504 (Limitations of Usual Tools): Warn about sed stripping
2505 leading white space from text. From Bruno Haible.
2507 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
2509 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
2510 compiler complains about it, even if things works after the
2511 complaint. Problem reported by Peter O'Gorman.
2513 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
2514 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
2515 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
2517 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
2519 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
2520 after -R regardless of host. Patrick Welche reports that this
2521 fixes things on NetBSD 3.99.

2529 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
2531 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
2532 under AC_C_VOLATILE.
2533 (Volatile Objects): Be a little less skeptical about what
2534 "volatile" means. Derived from thoughts by Ben Pfaff in
2535 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
2537 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2539 * doc/autoconf.texi: Fix some typos.
2541 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
2543 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2544 more globally, since the 2006-06-30 patch didn't suffice. Problem
2545 reported by Keith Marshall. Also, don't bother with builddir2,
2546 since it shouldn't be needed any more.
2548 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
2550 * doc/autoconf.texi (Generic compiler characteristics):
2551 Document AC_COMPUTE_INT. Fix wrong statements on Default
2552 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.

2557 AC_COMPUTE_INT.
2559 * NEWS: Document change.
2561 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
2563 * doc/autoconf.texi (Volatile Objects): New section.
2565 * NEWS: Document previous change.
2567 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
2569 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
2570 Require that long long int be at least 64 bits wide. C99 requires
2571 this and enough programs depend on it so we should check for it.
2572 Bruno Haible reports in
2573 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
2574 that long long int is 32 bits wide with some nonstandard compilers.
2575 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
2577 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
2579 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2580 to a nonexistent file, so that we don't have to worry about
2581 a local site configuration that doesn't use /usr/local.
2582 Problem reported by Keith Marshall in
2583 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
2585 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
2587 * doc/autoconf.texi: Be more consistent about using @acronym with
2588 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
2589 quite right (it talked about "OSF/Tru64", even though the
2590 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
2591 and it even mentioned "OSF 4"!) and at this point there's little
2592 reason to talk about OSF any more, since it died in 1994.
2593 (Specific Compiler Characteristics): Simplify example of
2594 negative-size array.
2595 (File Descriptors): Reorder to make the text flow better.
2596 Remove joke about "appreciate the various levels"; I didn't get it.
2597 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
2598 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
2599 (File Descriptors, Limitations of Usual Tools):
2600 Tone down the advice against renaming or removing open files.
2601 (Limitations of Usual Tools): Add a new section, on 'rm'.
2603 2006-06-26 Stepan Kasal <kasal@ucw.cz>
2605 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
2606 -lXt in LIBS, idea from Karsten Hopp; this was due since
2607 this change:
2609 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2610 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2611 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2612 (which belong to Xt, not X itself). See Debian bug 327655.
2614 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2616 * configure.ac (AC_INIT): Bump to 2.60a.
2617 * NEWS: Update.
2619 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2621 Version 2.60.
2623 * configure.ac, NEWS: Update.
2625 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2627 * config/texinfo.tex: Sync from upstream.
2629 * bin/autom4te.in (handle_traces): Transform the `@S|@'
2630 quadrigraph correctly in traces.
2632 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
2633 Fix typos.
2635 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
2636 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
2637 not defined.
2638 * doc/autoconf.texi (Changed Directory Variables): New node,
2639 to document the whole `datarootdir' business a bit better.
2640 * NEWS: Update.
2641 * tests/torture.at (datarootdir workaround): Extend test.
2642 Prompted by report by Alexandre Julliard.
2644 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
2646 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
2647 when using default mode of IBM C 6 for AIX. Problem and two-line
2648 fix reported by Larry Jones.
2650 2006-06-22 Alexandre Julliard <julliard@winehq.org>
2652 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
2653 about literal '${datarootdir}' if a definition is found in the
2654 output file.
2656 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
2658 * NEWS: Use "M4" rather than "m4" when appropriate.
2659 Problem reported by Eric Blake.
2660 * doc/autoconf.texi: Likewise.
2661 Use @acronym around BSD, GCC, and GNU when appropriate.
2662 (Why GNU M4): Renamed from "Why GNU m4".
2663 (Redefined M4 Macros): Mention that Posix
2664 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
2665 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
2666 to int.
2668 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2670 * bin/autom4te.in (handle_output): Do not forbid the empty
2671 pattern.
2672 * tests/tools.at (autoconf: the empty token): New test.
2674 2006-06-20 Stepan Kasal <kasal@ucw.cz>
2676 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
2677 calls, so that we do not care whether they are LIFO or FIFO;
2678 in the m4_wrap, do not check which diversion is the topmost
2679 one, just check that the stack is balanced at the end.
2680 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
2681 base diversion forever--pop the previous diversion before
2682 opening the new one; consequently, remove the m4_wrap call.
2683 * lib/autotest/general.m4 (AT_INIT): Likewise.
2684 * tests/m4sugar.at: Do not use
2685 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
2687 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
2688 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2690 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
2691 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
2692 Rework example of m4wrap token-pasting trouble so that it doesn't
2693 care whether it's LIFO or FIFO.
2694 Fix some "contrary to"s that are awkward in English.
2696 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2698 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
2699 to `yes' instead of `int$1_t' if the type is found, for more
2700 consistent configure output (where $1 is the number of bits).
2701 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
2702 Suggested by Bruno Haible.
2704 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
2705 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
2706 with system headers. Report by Bruno Haible.
2708 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2710 * config/config.guess, config/config.sub: Sync from upstream.
2712 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
2713 in order to avoid picking up an older installed frozen m4sh.m4f.
2714 Besides an outdated shell startup, this could have been created
2715 by an earlier M4 version with incompatible frozen file format.
2717 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
2719 * README: Recommend m4 1.4.4 instead of 1.4.3..
2720 * doc/autoconf.texi: Likewise.
2721 (Special Chars in Names): Say that $(.FOO) is portable, as
2722 suggested by Stepan Kasal.
2723 (Installation Directory Variables, Build Directories):
2724 (Automatic Remaking, Subdirectories, Fortran Compiler):
2725 (Making testsuite Scripts, Defining Directories):
2726 Quote variable usages better.
2727 (Making testsuite Scripts): Add clean-local rule to makefile
2728 snippet, by Eric Blake.
2729 (Installation Directory Variables): Fix table item font.
2730 Reword slightly to clarify. Generalize advice about
2731 not using special characters to include all file-related
2732 vars, not just VPATH.
2733 (Special Chars in Variables): Warn about special characters in
2734 $(srcdir) too.
2735 (Assignments): Clarify default-value example as suggested by
2736 Ralf Wildenhues in
2737 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
2738 (Special Shell Variables): Note leading ./ or ../, as suggested
2739 by Eric Blake.
2740 (Limitations of Builtins): Under cd, warn about CDPATH.
2741 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
2742 Ralf Wildenhues.
2744 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2746 * doc/autoconf.texi (Configuration Actions): Remove duplicate
2747 `@var', for texi2html.
2748 (Systemology): Some more word wrapping, for DVI output.
2749 (autom4te Invocation): The short option for `--melt' is `-M',
2750 not `-m'.
2752 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
2754 * doc/autoconf.texi: More formatting and English tweaks,
2755 many suggested by Ralf Wildenhues.
2756 Reword to avoid "@code{...}'s" and the like, since it's ugly
2757 with Emacs info mode. discontents -> woes.
2758 Put a few "will"s back. time stamp -> timestamp.
2759 side-effect -> side effect.
2761 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
2763 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
2764 Warn about $@ not persisting. Problem reported by Julien Danjou in
2765 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
2766 (Special Chars in Names): Renamed from Leading _ in Macro Names.
2767 Mention other special chars, too.
2769 2006-06-14 Eric Blake <ebb9@byu.net>
2771 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
2773 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
2775 * doc/autoconf.texi: Some systematic minor improvements, as
2776 follows. Use "makefile" when talking about makefiles
2777 generally (which might be named "makefile" or "Makefile" or even
2778 "foo.mk"), "Makefile" when talking about a specific makefile
2779 called "Makefile". This unclutters the text from weird quotes
2780 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
2781 values" rather than "@var{foo}s" and similar constructs containing
2782 "}s". Use "Make rules" rather than "Makefile rules". Minor
2783 English-language improvements. Change the prefix "sub-" to "sub"
2784 and "re-" to "re".
2785 Put blank lines around examples more consistently.
2786 Avoid "rather" and "very" as intensifiers.
2787 Avoid "will" as an auxiliary.
2788 (Limitations of Make): Split this node into....
2789 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
2790 (Leading _ in Macro Names, Backslash-Newline-Newline):
2791 (Backslash-Newline Comments, Long Lines in Makefiles):
2792 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
2793 (obj/ and Make, make -k Status, VPATH and Make):
2794 (VPATH and Double-colon, $< in Explicit Rules):
2795 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
2796 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
2797 New nodes, resulting from splitup of Limitations of Make.
2798 All cross-references changed. Raise the top node from
2799 a section to a chapter, and all subnodes accordingly.
2800 Redo the introductory wording to match the new organization.
2801 (Installation Directory Variables): Use an example that is
2802 closer to what Autoconf actually does. Mention that VPATH's
2803 value should not contain metacharacters or white space.
2804 (Fortran Compiler): Fix a VPATH bug in an example.
2805 (Leading _ in Macro Names): Mention that this problem is no longer
2806 of practical concern.
2807 (VPATH and Make): Reword the advice to make it clearer
2808 that Autoconf and Automake support VPATH in non-GNU make, but
2809 many packages have bugs in this area.
2810 ($< in Explicit Rules): Refer to Build Directories rather
2811 than using a (non-VPATH-safe) example.
2812 (Automatic Rule Rewriting): Mention the sort of disaster that
2813 can ensue with Solaris-style rule rewriting with VPATH.
2815 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2817 * doc/install.texi (Compilers and Options): Weaken the
2818 suggestion to use GNU make for VPATH builds.
2820 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
2821 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
2823 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
2824 in regular expression.
2826 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2828 * doc/autoconf.texi (Installation Directory Variables):
2829 Drop extra @samp from `@table @samp' item.
2830 (Limitations of Usual Tools): Comment fix.
2831 Do not nest @samp just to point to other table items.
2832 (Writing testsuite.at) <AT_CHECK>: The second argument to
2833 `@dvar' is already @samp'ed.
2834 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
2835 do not use @var in the second argument.
2837 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
2839 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
2840 $as_shell.exe too. Problem reported by Andreas Buening in
2841 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
2843 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2845 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
2846 `unused variable' compiler warning, for `-Wall -Werror'.
2847 Reported by Jaap Haitsma in
2848 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
2850 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
2852 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
2853 case the compiler dumps core. Problem reported for
2854 OpenServer 5.0.7 by Tim Rice in
2855 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
2856 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2857 Likewise.
2859 2006-06-06 Tim Rice <tim@multitalents.net>.
2861 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
2862 "ERROR" only shows up in "make check" output if there is an
2863 error.
2865 2006-06-06 Eric Blake <ebb9@byu.net>
2867 * tests/tools.at (automatically allowed tokens): Fix typo.
2869 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2871 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
2873 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
2874 typically overflows on x86 CPUs, even though the C standard
2875 requires otherwise.
2877 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2879 * configure.ac (AC_INIT): Bump to 2.59e.
2880 * NEWS: Update.
2882 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2884 Version 2.59d.
2886 * config/texinfo.tex: Sync from upstream.
2888 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
2889 seen, invoke libtoolize with `--ltdl' argument.
2890 * lib/autom4te.in (Autoreconf-preselections): Adjust.
2891 * NEWS: Update.
2892 Suggested by Eric Blake.
2894 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2896 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
2897 reported by Ralf Wildenhues.
2898 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
2900 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2902 * THANKS: Update.
2904 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2906 * doc/autoconf.texi: Modernize some of the references to Solaris.
2908 2006-06-05 Stepan Kasal <kasal@ucw.cz>
2910 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
2911 message issued by AC_REQUIRE.
2912 * tests/m4sugar.at: Check m4_require's error message.
2913 * tests/base.at: Check AC_REQUIRE's error message.
2914 * tests/local.at (AT_CHECK_M4): New macro, almost identical
2915 to...
2916 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
2917 AT_CHECK_M4.
2918 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
2919 `expout' as the last parameter.
2920 * tests/tools.at: Adapt to the above change.
2922 2006-06-04 Stepan Kasal <kasal@ucw.cz>
2924 * doc/autoconf.texi (Limitations of Usual Tools): Correct
2925 information about race-free implementations of mkdir.

2932 * doc/autoconf.texi (autom4te Invocation): Likewise.
2934 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
2936 * NEWS: GNU make now recommended for VPATH builds.
2937 Mention that some macros are now documented to be obsolescent.
2938 * doc/autoconf.texi:
2939 Prefer "current" to "modern" to describe
2940 currently-used (albeit perhaps old-fashioned) hosts.
2941 Mention which ancient features no longer need to be worried about.
2942 setgid -> set-group-ID
2943 setuid -> set-user-ID (these are the Posix terms)
2944 Fix some misuses of "only".
2945 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
2946 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
2947 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
2948 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
2949 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
2950 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
2951 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
2952 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
2953 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
2954 Mention that these macros are obsolescent.
2955 (Installation Directory Variables): shall -> should
2956 (File Descriptors): Mention that 0, 1, 2 might get reopened.
2957 Mention that it's now safe to use 3 and 4.
2958 (Limitations of Usual Tools): cp -r is now specified by Posix.
2959 Omit longwinded and obsolescent discussion of cp -f.
2960 Modernize discussion of expr, ls.
2961 (Limitations of Make): Modernize discussion of VPATH builds.
2962 Mention $? as a workaround in some cases.
2963 * doc/install.texi (Basic Installation):
2964 Mention "./configure; make; make install" first. Be more
2965 specific about why this file is generic. Remove unnecessary
2966 parens. Remove misleading "only". Remove obsolete advice
2967 about csh. Don't say "configure" takes awhile; say it
2968 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
2969 and CC=c99 rather than CC=c89, as these are blessed by current
2970 Posix. Recommend GNU make if doing a VPATH build.
2972 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
2974 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
2975 examples involving shell prompts.
2977 2006-06-02 Stepan Kasal <kasal@ucw.cz>
2978 and Paul Eggert <eggert@cs.ucla.edu>
2980 * doc/autoconf.texi (Here-Documents): Add details about the
2981 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
2982 use "here-documents" instead of "here documents".
2984 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2986 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
2988 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
2990 * doc/autoconf.texi (File System Conventions): Warn about ":"
2991 anywhere in directory names.
2993 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
2995 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
2996 about quoting the case statement, just in case.
2997 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
2998 was fixed in ksh93g; reported by Ralf Wildenhues.
3000 2006-05-31 Stepan Kasal <kasal@ucw.cz>
3002 * doc/autoconf.texi (System Services): Do not document
3003 overriding EXEEXT via ac_cv_exeext=ext.
3004 (Particular Programs) <AC_PROG_MKDIR_P>:
3005 Document that ${MKDIR_P} understands --.
3006 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
3007 comment.
3009 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3011 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
3012 argument with leading hyphen. Problem reported by Paul Eggert.
3014 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3016 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
3017 about quoting ac_try: quote all of it, if any of it seems suspicious.
3018 This means we don't have to worry about ${ or sed any more.
3019 Also, double-quote the case statement, to work around misuses via
3020 underquoting as reported by Ralf Wildenhues in
3021 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
3022 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
3023 undocumented and dangerous macro.
3024 Problem reported by Ralf Wildenhues in
3025 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
3027 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3029 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
3030 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
3031 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
3033 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3035 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
3036 since evidently some packages rely on the old, broken behavior.
3037 Problem reported by Ralf Wildenhues in
3038 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
3039 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
3040 pre-2006-05-26 definitions, but leave in the comments that
3041 these macros are dangerous and should not be used.
3042 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
3043 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
3044 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
3045 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
3046 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
3048 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
3050 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
3051 the use of 'tr', since this is our only use of 'tr'.
3053 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3054 and Paul Eggert <eggert@cs.ucla.edu>
3056 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
3057 Don't assume 'grep' works on long lines, since AIX grep doesn't.
3059 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3061 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
3062 the output file in the `${datarootdir}' test.
3064 2005-05-28 Stepan Kasal <kasal@ucw.cz>
3065 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3067 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
3068 mention of `datarootdir' in the input file(s), but literal
3069 `${datarootdir}' in the output file, and we haven't warned yet,
3070 then warn as well: the user may have (erroneously) used
3071 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
3072 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
3073 * tests/torture.at (datarootdir workaround): Extend this test.
3074 * NEWS: Update.
3076 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3077 and Paul Eggert <eggert@cs.ucla.edu>
3079 * doc/autoconf.texi (autoheader Invocation): The first argument to
3080 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
3081 alternatives and clear up the language a bit.
3083 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
3085 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
3086 ac_config_guess, ac_config_sub, ac_configure.
3087 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3088 Fix typo that prevented an unnecessary space from being removed.
3089 Problems reported by Ralf Wildenhues in:
3090 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
3092 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
3094 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
3095 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
3096 Don't use the term "thread-safe" to talk about mkdir race
3097 conditions, since the problem is more a process than a thread
3098 issue. Problem reported by Stepan Kasal in:
3099 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
3100 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
3101 the test for 'install' more closely. Look at MKDIR_P first.
3102 Look in the PATH, and at /opt/sfw/bin.
3103 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
3104 Don't bother to try mkdir -p, since we already check mkdir --version;
3105 just look at the version number. (There's no easy way to check
3106 for race-free implementations.)
3107 * tests/tools.at (autoconf: subdirectories): Adjust to above
3108 changes, since MKDIR_P now might end in "/mkdir -p".
3110 * doc/autoconf.texi (autoheader Invocation): Mention that the
3111 first arg of AC_DEFINE_UNQUOTED must be a literal.
3112 Problem reported by Ben Pfaff in
3113 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
3115 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
3116 * doc/autoconf.texi (Special Chars in Variables): New section.
3117 (Preset Output Variables): Warn about special chars in CPPFLAGS.
3118 (Installation Directory Variables): Quote $(datadir) better.
3119 (Limitations of Builtins): Describe some of eval's trickiness.
3121 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
3122 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
3123 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
3124 in front of every arg, not just trailing args. Quote apostrophes.
3125 (_AC_EVAL_ECHO): New macro.
3126 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
3127 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
3128 removed.
3129 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
3130 exposed by quoting of eval argument. Put the command on line line
3131 so it logs better.
3132 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
3133 (_AC_PATH_X, AC_PATH_X): Quote more safely.
3134 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
3135 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
3136 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
3137 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
3138 Use eval more safely.
3139 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
3140 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
3141 to be replaced.
3142 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
3143 lines, exposed by quoting of eval argument.
3145 2006-05-26 Stepan Kasal <kasal@ucw.cz>
3146 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3148 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
3149 initialization of `ac_cv_exeext', do not override it if it was
3150 already set, unless it was set to `no', for compatibility with
3151 Autoconf-2.13, and comment this.
3152 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
3153 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
3154 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
3155 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
3156 Document that this test may be overridden by setting
3157 `ac_cv_exeext'.
3159 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3161 Revert these two patches:
3163 2006-04-06 Eric Blake <ebb9@byu.net>
3164 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3165 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3166 2006-04-01.
3168 2006-04-01 Stepan Kasal <kasal@ucw.cz>
3169 Clean up _AC_COMPILER_EXEEXT* macros.
3170 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3171 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3172 ac_file to the name of the default output file and call
3173 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3174 initial `rm' of the candidate files...
3175 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3176 the same list in subsequent `rm' calls, and for the temporary
3177 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3178 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3179 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3180 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3181 no longer needed) by libtool. Make it a cache check.
3182 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3183 copied here by mistake.
3184 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3185 _AC_COMPILER_EXEEXT.
3186 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
3187 _AC_COMPILER_OBJEXT directly.
3188 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3190 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3192 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
3193 Fix description of how the buggy `sed' works.
3195 2006-05-25 Noah Misch <noah@cs.caltech.edu>
3197 Sync from Automake:
3199 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
3200 ENOLCK. Only mention `make -j' when applicable. Only raise
3201 fatal errors when `make -j' is involved. Improve error message.
3203 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3205 * doc/autoconf.texi (Here-Documents): We now know more about
3206 the variable expansion in here documents bug.
3207 Thanks to Tim Rice and Stepan Kasal.
3209 * doc/autoconf.texi (Making testsuite Scripts): Add an example
3210 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
3212 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3214 * tests/autotest.at (Multiline command from M4 expansion):
3215 No failure to be expected if the shell quotes newlines in
3216 commands in the `set -x' output. Report by Tim Rice.
3217 * THANKS: Update.
3219 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3221 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
3222 expansion in the here-documents used by config.status, as that
3223 runs afoul of the Korn shell version M-12/28/93d bug described in
3224 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
3225 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
3226 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
3228 2006-05-23 Jim Meyering <jim@meyering.net>
3230 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
3231 Fix typo introduced with 2006-04-02 change. It reversed the sense
3232 of the test.
3234 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3236 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
3237 ac_dB slightly, to save bytes in the script.
3238 Max out at 50 lines, rather than 96; this is more likely
3239 (though not guaranteed) to avoid obscure 'sed' failures.
3241 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3243 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
3244 `tr -d -' as bad option argument. Work around this by deleting
3245 an unrelated character.
3246 Report by Tim Rice <tim@multitalents.net>.
3248 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
3249 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3250 Stepan Kasal <kasal@ucw.cz>
3252 * doc/autoconf.texi (Particular Programs): Do not promise that
3253 we always prefer the GNU version of the program, and that we
3254 search according to PATH; both rules can have exceptions.
3255 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
3256 AC_PROG_SED. Move descriptions of limitations
3257 to the Limitations of Usual Tools section.
3258 (Limitations of Usual Tools) <sed>: Mention script length
3259 limitations with Solaris /usr/ucb/sed.
3260 <grep>: Fix wording for empty alternative. Mention that -c and
3261 -l should not be combined, and that -E and -F should not be
3262 combined.
3264 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3265 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3267 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
3268 limits in Solaris 8 /usr/ucb/sed by testing a long script.
3270 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3272 * doc/autoconf.texi (Defining Symbols): Literal parameter of
3273 AC_DEFINE is now passed to m4_pattern_allow.
3274 * NEWS: Mention that; likewise for AC_SUBST.
3275 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
3276 the parameter to m4_pattern_allow.
3277 * tests/tools.at: Add a check for that.
3279 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3281 * lib/autoconf/status.m4: Fix typos.
3283 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3285 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
3286 only the files that this macro generates.
3288 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3290 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
3291 the HP-UX sed limitation of 99 commands, labels do not count.
3292 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
3293 in the comment.
3294 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
3296 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3298 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3299 Import the following fix from coreutils:
3301 2006-01-13 Jim Meyering <jim@meyering.net>
3303 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
3304 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
3305 not double-quote uses of that variable, to accommodate the rare
3306 case in which getmntent is available in none of the libraries
3307 checked. This happens at least on FreeBSD 5.0.
3309 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
3311 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
3312 ac_config_guess, ac_config_sub, and ac_configure, since evidently
3313 some other programs unwisely rely on these undocumented vars.
3314 But put in warning comments about them.
3315 Problem reported by Ralf Wildenhues in
3316 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
3317 * NEWS: Document that these variables are intended to go away.
3319 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3321 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
3322 and set the language to C++ (analogous to the equivalent Fortran
3323 tests).
3325 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
3326 * doc/autoconf.texi (C++ Compiler): Document it.
3327 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
3328 * NEWS: Update.
3330 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
3332 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
3333 that caused config.status to generate 100-command sed scripts; the
3334 portable limit is 99.
3336 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3338 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
3339 variable `ac_d' instead of `d' to avoid infringing namespace.
3340 Report by Ralf Menzel.
3342 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
3344 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
3345 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
3346 * tests/tools.at (autoconf: subdirectories): New test, taken from
3347 the corresponding problem report by Ralf Wildenhues in:
3348 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
3350 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
3351 Quote some uses of shell variables if they might suffer unexpected
3352 globbing. This doesn't fix all instances of quoting problems that
3353 I found, just the easy ones that look safe.
3354 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
3355 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
3356 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
3357 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
3358 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
3359 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
3360 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
3361 Likewise.
3362 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
3363 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
3365 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3367 * bin/autoreconf.in ($help): Reword according to the manual.
3368 Suggested by Olly Betts.
3370 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
3371 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3373 * bin/autoreconf.in: Pass the directory argument to
3374 `require_configure_ac'. Fix comment.
3375 * tests/torture.at (Configuring subdirectories): Expose this.
3376 Reported by Olly Betts.
3378 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3380 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
3381 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
3382 Automake as follows:
3384 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
3385 `$configure_in' instead of `configure.in', to preserve
3386 directory component.
3388 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3390 * config/config.guess, config/config.sub, config/texinfo.tex,
3391 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
3393 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
3395 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
3396 test for C99 conformance; (bool) 0.5 is an integer constant
3397 expression, but (bool) -0.5 is not. Problem reported by Fedor
3398 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
3400 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
3402 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
3403 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
3404 Warn about obsolete install-sh files. Remove stray sentence
3405 fragment and fix cross reference.
3406 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
3407 install -d; this undoes the 2006-05-10 change.
3408 (MKDIR_P): Mark with AN_MAKEVAR.
3409 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
3410 that we don't require $INSTALL to be thread-safe. Move comments
3411 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
3412 of AC_PROG_INSTALL. Output a message saying that we're checking
3413 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
3414 MKDIR_P instead of AC_SUBST.
3415 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
3416 Special magic for MKDIR_P, too.
3417 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
3418 a dnl.
3419 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
3421 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
3423 Sync from Automake, as follows:
3425 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3426 * config/install-sh: Initialize IFS, so field splitting isn't
3427 turned off later.
3428 * config/mkinstalldirs: Likewise.
3429 * config/missing: Remove superfluous quotes. Replace all uses of
3430 `[' by `test', for consistency, and for..
3431 * config/missing (sed_minuso, sed_output): New variables.
3432 (autom4te, help2man, makeinfo): Use them. Unifies detection of
3433 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
3434 Fixes `missing' to detect `--output' for help2man. Fixes
3435 PR automake/483. Report by Dennis J. Linse.
3436 (autom4te): Document in `missing --help'.
3438 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3440 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
3441 * config/install-sh: Don't use 'path' to talk about file names,
3442 as per GNU coding standards. Close a race condition reported by Ralf
3443 Wildenhues and Stepan Kasal. There is still a race condition
3444 on hosts that predate Posix 1003.1-1992, but we can't help this.
3445 Don't mishandle weird characters like space on pre-Posix hosts.
3446 Invoke mkdir at most once per dir arg on pre-Posix hosts.
3447 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
3448 AC_PROG_MKDIR_P from AS_MKDIR_P.
3449 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
3450 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
3451 earlier editions are not (including Automake 1.8.3).
3452 Do not suggest mkinstalldirs for thread-safety.
3453 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
3454 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
3455 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
3456 presence of special characters and race conditions.
3457 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
3458 in Autoconf's name space.
3460 2006-05-10 Bruno Haible <bruno@clisp.org>
3461 and Paul Eggert <eggert@cs.ucla.edu>
3463 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
3464 from Automake with minor changes.
3465 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
3467 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3469 * config/install-sh: Update to Automake CVS version, as follows:
3470 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3471 * lib/install-sh: Simplify the expr implementation of dirname.
3472 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
3473 * lib/install-sh: Handle --, and diagnose unknown options.
3475 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3477 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
3478 `./autom4te' to create `./testsuite', since the `all' target
3479 will ensure its presence, but `installcheck' should not create
3480 the uninstalled wrappers.
3482 * tests/torture.at (Unusual Automake input files): Skip if we
3483 detect automake < 1.8.
3485 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3487 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
3488 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
3489 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
3490 * NEWS: Update.
3492 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3494 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
3495 munge (multiple) white space and other oddities.
3496 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
3497 single quotes in variable assignment.
3498 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
3499 and similar failures by adding multiple spaces, tabs, and other
3500 special characters.
3501 Report and different test suggested by Francesco Romani
3502 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
3504 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
3505 single quotes, we only need to search for single quotes; this
3506 both simplifies the search pattern, and makes us less
3507 susceptible to `echo' variations for arguments not containing
3508 single quotes.
3509 (_AC_ARG_VAR_VALIDATE): Likewise.
3511 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3513 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
3514 `$*' and IFS concatenation issue with traditional shells and
3515 bash-2.04. Report by Seanster@Seanster.com.
3517 2006-05-03 Bruno Haible <bruno@clisp.org>
3519 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
3520 precisely which Mac OS X versions have the od problem.
3522 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3524 * doc/autoconf.texi: Use @option systematically.
3526 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3527 and Bruno Haible <bruno@clisp.org>
3529 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
3530 about 'od'.
3531 (Integer Overflow): Mention the special case of integer division
3532 overflow.
3534 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3536 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
3537 traditional shells like the Solaris one that do not use the
3538 first IFS character for assembling `$*'.
3539 Prompted by a related report from autoconf_bug@nro.ca.
3541 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
3542 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3544 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
3545 Mention more problems with the -e option.
3547 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3549 * NEWS: Typo.
3550 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
3552 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
3553 in URLs to improve DVI formatted output (requires texinfo 4.6).
3554 (System Services, Systemology, Shellology): Likewise.
3555 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
3556 output.
3558 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
3559 continuous text.
3560 (Runtime): Fix macro argument names to match description:
3561 `action-if-found' -> `action-if-true' and similarly.
3562 (Obsolete Macros): Likewise.
3563 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
3564 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
3565 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
3567 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3569 * doc/autoconf.texi (Limitations of Make): Clean up markup.
3571 * ChangeLog: Typo.
3572 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
3573 DVI output.
3575 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3580 * tests/local.at: Likewise.
3582 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
3584 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
3585 (Integer Overflow, Null Pointers, Buffer Overruns):
3586 (Floating Point Portability, Exiting Portably): New sections.
3587 (Writing Test Programs): Fix some langauge. Recommend exiting
3588 with status 1, not merely nonzero. Clarify exit declaration.
3589 (Run Time): Move C exit status stuff to new Exiting Portably section.
3590 (Systemology): Mention Posix and levenez. Update v7 reference.
3591 (Portable Shell): Mention the Posix shell.
3593 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3595 * bin/autoconf.as (me): Replace by as_me.
3597 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
3599 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
3600 since as_me isn't set yet.
3602 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3604 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
3605 a few minor bugs in this area.
3607 * doc/autoconf.texi (Programming in M4sh): Comment out the
3608 documentation of AS_BASENAME, for now.
3609 (Shell Substitutions): Do not use AS_DIRNAME in an example.
3610 (Limitations of Builtins) <basename>: Do not refer to
3611 AS_BASENAME.
3612 * bin/autoconf.as (me): Don't use AS_BASENAME.
3613 (dir): Remove the unused variable.
3614 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
3615 AS_DETECT_REQUIRED. All uses changed.

3617 All uses changed.
3618 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
3619 (AS_BASENAME): Use "basename --" to protect against leading "-".
3620 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
3621 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
3622 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
3623 (_AS_DIRNAME_PREPARE): Likewise.
3624 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
3625 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
3626 (AS_DIRNAME): Use "dirname --".
3628 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3630 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
3631 of "run time" and "run-time" changed to "runtime", for consistency.

3638 with more accuracy and detail.
3640 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3642 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
3643 Archive is not officially `GNU' any more. Update URL.
3644 (Defining Directories): Likewise
3645 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
3647 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3649 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
3650 newline from the `trap' code to finish `config.log'; the NetBSD
3651 /bin/sh resets the exit status after an empty command, as
3652 documented in doc/autoconf.texi.
3653 Reported by Dalibor Topic <robilad@kaffe.org>.
3655 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
3657 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
3658 Suggested by Bruno Haible.
3660 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
3662 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
3663 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
3664 Instead, just list the shells that we know work.
3665 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
3666 changed. Be more cautious about the _cv_ variable.
3667 * tests/tools.at (Syntax of the shell scripts): Check the
3668 _cv_ variable once, at first, to avoid an internal autoconf error
3669 when sh -n does not work.
3671 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3673 * lib/Autom4te/FileUtils.pm: Sync from Automake.
3675 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
3677 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
3678 use ">&-" since we're only 99.999% sure that this is portable,
3679 and since the MinGW bug is fixed in a different way.
3680 * lib/autotest/general.m4 (AT_INIT): Likewise.
3682 2006-04-16 Stepan Kasal <kasal@ucw.cz>
3684 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
3685 before opening config.log, to avoid hitting a bug on MinGW.
3687 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
3689 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
3690 AS_MESSAGE_LOG_FD before reopening it onto the log file.
3691 This works around a MinGW bug reported by Eric Paire.
3692 Make sure that all writes to the log file append to it,
3693 rather than possibly losing data.
3694 * lib/autotest/general.m4 (AT_INIT): Likewise.
3696 2006-04-14 Stepan Kasal <kasal@ucw.cz>
3698 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
3699 description.
3701 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3703 * NEWS: Update.
3705 * configure.ac (AC_INIT): Bump to 2.59d.
3707 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3709 Version 2.59c.
3711 * Makefile.maint (news-date-check): Do not require a leading `*'
3712 before the release date in NEWS.
3714 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3715 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3717 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
3718 the instantiated file do not contain the string 'datarootdir'
3719 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
3720 @mandir@, replace the reference '${datarootdir}' by the value.
3721 * tests/torture.at (datarootdir workaround): New test.
3722 * NEWS: Advertise this temporary fixup.
3723 Based on a patch by Bruno Haible, reported and analyzed by
3724 Paul Eggert and Noah Misch.
3726 2006-04-12 Eric Blake <ebb9@byu.net>
3728 * tests/autotest.at (Debugging a failed test): Fix comment.
3730 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3732 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
3733 all the changes since 2006-04-07.
3735 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3737 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
3738 succeeded, but `ln -s file dir' failed, take care to remove the
3739 leftover target before the next test, to prevent its spurious
3740 failure; also make sure `ln file dir' works before selecting it.
3741 Thanks to Keith Marshall for pointing this out.
3742 * THANKS: Update.
3744 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
3745 assignments in `at_debug_args', so that we put them correctly
3746 in the `run' script.
3747 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
3748 Reported by Eric Blake.
3750 2006-04-11 Eric Blake <ebb9@byu.net>
3752 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
3753 top-level tests after micro-suite has been run. Used in...
3754 (Debugging a successful test, Debugging script and environment),
3755 (Debugging a failed test): ...these new tests. The first of these
3756 is fixed by...
3757 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
3758 macro, split out from...
3759 (AT_INIT): ...here, so that using -d also generates a run script.
3760 Document that -d inhibits top-level logging.
3761 * doc/autoconf.texi (testsuite Invocation): Document that -d only
3762 inhibits top-level logging; debug scripts are created.
3764 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
3765 check.
3766 * tests/autotest.at (Empty test, Empty check): New test to check it.
3768 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
3769 from gcc.
3771 2006-04-10 Stepan Kasal <kasal@ucw.cz>
3773 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
3774 the files if a problem appears. Make the empty *.at files
3775 read-only, too. Proposed by Ralf Wildenhues.
3777 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3779 * config/Makefile.am: Add comment to force updated Makefile.in.
3781 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
3782 space only patch to this file, this patch causes the Makefile.in
3783 files that include freeze.mk to be updated, and thus have a
3784 newer time stamp again, which in turn makes a pristine CVS
3785 checkout have correct time stamps.
3787 * Makefile.maint (cvs-sv): New macro, to be used..
3788 (config.guess-url_prefix, config.sub-url_prefix)
3789 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
3790 point to CVS text checkout of Gnulib files.
3791 (copyright-check): Bump current year.
3792 (announcement): Do not hard-wire `./announce-gen'.
3793 (cvs-update): Propagate failures of `cvs' and `move-if-change'
3794 correctly.
3795 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
3796 `chmod +x'.
3797 (wget_files): Update config.guess, config.sub, texinfo.tex by
3798 `wget-update', now that their URLs work again.
3800 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3802 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
3803 Problem noted by Paul D. Smith.
3805 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3807 * doc/autoconf.texi: Remove unused words from word list.
3808 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
3809 .x-sc_trailing_space: New files.
3811 * doc/standards.texi: Sync from gnulib.
3813 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
3814 `LIBOBJDIR' as experimental.
3816 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
3817 with a target directory; it's internally implemented as `cp'
3818 anyway, but since Autoconf advertises the possibility to use
3819 a target directory when LN_S is `ln -s', we need to find out.
3820 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
3821 analyzed by Keith Marshall <keith.marshall@total.com>.
3823 * THANKS: Update.
3825 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3827 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
3828 confdefs.h as-is. In general, if it has backslash-newline or the
3829 like, then it doesn't work either to sort or to remove empty
3830 lines.
3832 2006-04-09 Stepan Kasal <kasal@ucw.cz>
3834 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
3836 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
3838 * lib/autom4te.in (Automake-preselections): Preselect
3839 _AM_SUBST_NOTMAKE.
3841 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3843 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
3844 apostrophe within a single-quoted string, as this is the usual
3845 tradition and is easier to read than '"'"'. Don't rely on the
3846 shell treating "$/" like '$/'. Use a more-consistent indenting
3847 style for the trap.
3849 2006-04-09 Eric Blake <ebb9@byu.net>
3851 * tests/autotest.at (Backquote command substitution),
3852 (Multiline backquote command substitution): Remove mistaken
3853 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
3854 applied...
3855 (Parenthetical command substitution, Multiline parenthetical
3856 command substitution): here.
3858 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3860 Import macros from gnulib (often changing their name).
3862 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

3874 (Pointers): Add Gnulib URL.
3875 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
3876 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
3877 Gnulib section.
3878 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
3879 suggest a #define rather than a typedef for _Bool, and mention
3880 Gnulib rather than trying to substitute stdbool code.
3881 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
3882 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
3883 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
3884 AC_STRUCT_DIRENT_D_TYPE.
3885 (Particular Types): Mention stdint.h and inttypes.h as standard
3886 headers too.
3887 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
3888 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
3889 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
3890 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
3891 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
3892 (C Compiler): Move AC_C_LONG_DOUBLE to ...
3893 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
3894 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
3895 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
3896 (Coding Style). Don't mention m4_expand_once.
3897 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
3898 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
3899 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
3900 (AC_CHECK_FUNCS): Use it.
3901 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.

3904 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
3905 (AC_HEADER_ASSERT): New macro.
3906 (AC_HEADER_STDBOOL): Don't assume "#error" works.
3907 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
3908 Catch a bug in an HP-UX C compiler.
3909 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
3910 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
3911 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
3912 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):
3913 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
3914 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
3915 New macros.
3917 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
3918 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
3920 2006-04-08 Stepan Kasal <kasal@ucw.cz>
3922 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
3923 of the warning introduced by the 2001-08-28 change.
3925 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
3926 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3928 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
3929 variables shall be overriden by the cache.
3930 * tests/torture.at (AC_ARG_VAR): Test also with a first value
3931 that contains braces.
3933 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3935 Revert the patch from 2006-04-01 and only improve
3936 _AS_DETECT_BETTER_SHELL:
3938 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
3939 skip nonexistent directories.
3940 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
3941 only shell candidates which exist.
3942 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
3943 * lib/autotest/general.m4 (AT_INIT): No need to give three
3944 parameters to _AS_PATH_WALK.
3946 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
3947 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3949 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
3950 distinguish m4sugar macros.
3951 * tests/tools.at (autoupdating with aclocal and m4_include):
3952 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
3953 test case by Noah Misch <noah@cs.caltech.edu>.
3955 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3957 Revert my change from 2006-03-17, in other words:
3958 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
3959 and DUALCASE=1.
3960 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
3961 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
3962 it is set.
3964 2006-04-07 Eric Blake <ebb9@byu.net>
3966 * doc/autoconf.texi (Programming in M4sh): Document that
3967 AS_MKDIR_P exits the script on failure.
3968 * lib/autotest/general.m4: Remove redundant AS_ERROR.
3970 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3972 * config/elisp-comp, config/install-sh, config/mdate-sh,
3973 config/missing, config/mkinstalldirs: Sync from Automake.
3975 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
3976 from Automake.
3978 * doc/make-stds.texi: Sync from gnulib.
3980 2006-04-06 Eric Blake <ebb9@byu.net>
3982 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3983 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3984 2006-04-01.
3986 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
3987 Eric Blake <ebb9@byu.net>,
3988 Paul Eggert <eggert@cs.ucla.edu>,
3989 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3991 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
3992 whether `set' quotes correctly: redirect stderr of the tested
3993 `set', and use a subshell, for Ultrix; use `sed' instead of
3994 `grep' for zsh `set' which may write binary output; match only
3995 at the beginning of a line, to avoid false positives.
3996 In order to avoid false positives by unrelated variables with
3997 multiline content, put the dump algorithm in a subshell and
3998 unset all variables containing newlines (except some which are
3999 special to the shell). Warn about cache variables that are
4000 unset.
4002 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4004 * config/config.guess, config/config.sub, config/texinfo.tex:
4005 Sync from upstream.
4007 * tests/mktests.sh: Reword comments.
4009 * tests/mktests.sh: Only skip internal macros starting with
4010 `_AC_' or `__AC_'. Noted by Stepan Kasal.
4011 Update exclusion lists for the test suite to this end:
4012 (AC_ARG_VAR): Do test this now.
4013 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
4014 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
4015 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
4016 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
4018 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
4019 shell issue with double-quoted command substitutions of native
4020 commands.
4021 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
4022 Marshall.
4024 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
4025 no file matches the glob, discard the warning, set `nullglob'.
4026 (syntax-check): Likewise.
4027 (sc_cast_of_x_alloc_return_value): Likewise.
4028 (sc_cast_of_alloca_return_value, sc_error_exit_success)
4029 (sc_prohibit_jm_in_m4, .re-list, sc_unmarked_diagnostics)
4030 (m4-check): Likewise.
4031 (sc_system_h_headers): Do not print rule on execution.
4032 (sc_tight_scope): Do not fail for non-existing `src' directory.
4033 (sc_changelog): Skip the Copyright footer.
4034 * lib/autoconf/lang.m4: Remove trailing space.
4036 * lib/autoconf/status.m4: More replacements to
4037 <tab><space> where this makes sense.
4039 2006-04-06 Stepan Kasal <kasal@ucw.cz>
4041 * tests/Makefile.am (maintainer-check-posix):
4042 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
4044 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
4045 ac_config_<foo>s again, sometimes normalized, sometimes not.
4046 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
4047 (AC_CONFIG_COMMANDS): Do not do so here.
4048 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
4049 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
4050 2005-07-25 rewrite. Noticed by Noah Misch.
4052 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
4053 _AC_PRESERVE_HELP_ORDER, ...
4054 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
4056 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
4057 inside m4_expand_once; it is redundant.
4059 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
4060 for --help from Cygnus `configure.'
4062 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
4064 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
4065 on a patch proposed by Ralf Wildenhues.
4067 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
4069 * lib/autoconf/status.m4: Replace <space>''<tab> with
4070 <tab><space> where this makes sense.
4072 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
4073 Noah Misch <noah@cs.caltech.edu>
4075 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
4076 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
4077 * doc/autoconf.texi (Help Formatting): New node.
4078 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
4080 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4082 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
4083 lib/autoconf/specific.m4, lib/autoconf/status.m4,
4084 lib/autoconf/types.m4, lib/autotest/general.m4,
4085 tests/mktests.sh, tests/torture.at: White space cleanup:
4086 remove some SPACE before TAB, or add quoting ('' or @&t@).
4088 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
4090 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
4092 2006-04-05 Eric Blake <ebb9@byu.net>
4094 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
4095 empty test suite works.
4096 * tests/autotest.at (Empty test suite): Remove xfail.
4098 2006-04-05 Noah Misch <noah@cs.caltech.edu>
4100 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
4101 TAGS to ac_config_<foo>s.
4102 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
4103 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
4104 normalizing it, consistent it with previous releases.
4105 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
4107 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
4109 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
4110 Use simplified args that Eric Blake originally suggested.
4112 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
4114 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
4115 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
4116 Use 'comm' rather than N instances of grep; this also fixes a bug
4117 whereby substrings were incorrectly matched, causing us to not
4118 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
4119 (exclude_list): Exclude empty macros.
4120 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
4122 Use awk rather than grep -E or egrep, to avoid
4123 portability problems with regular expressions containing newlines.

4125 Switch from grep to awk syntax.
4126 (ac_exclude_script): Renamed from ac_exclude_egrep.
4127 (au_exclude_script): Renamed from au_exclude_egrep.

4203 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4204 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4205 ac_file to the name of the default output file and call
4206 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4207 initial `rm' of the candidate files...
4208 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4209 the same list in subsequent `rm' calls, and for the temporary
4210 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4211 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4212 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4213 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4214 no longer needed) by libtool. Make it a cache check.
4215 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4216 copied here by mistake.

4255 subordinate tools.
4256 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
4257 * doc/autoconf.texi (autoreconf Invocation): Document it.

4291 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4293 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
4294 switch all of them on and of when necessary. Fixes the bug when
4295 m4sugar macros (e.g., m4_define) were expanded after the first
4296 automatic update (e.g., after AC_PREREQ or AC_INIT).
4298 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>
4300 * doc/autoconf.texi (Programming in M4sh): Sharpen the descriptions

4327 * doc/autoconf.texi (Programming in M4sh): Mention AS_BASENAME.
4328 Give an example for AS_DIRNAME instead of referring to Posix..
4329 (File System Conventions): Put discussion of // versus / here, and
4330 modernize it a bit.

4345 * bin/autoscan.in: The value of find_configure_ac should be
4346 checked for existence, so we don't barf over a nonexisting
4347 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
4349 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4458 IFS even in case of empty `$PATH'.
4460 2006-03-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4462 * lib/autotest/general.m4 (AT_INIT) <at_optarg>: Optimize
4463 `expr' away if there is nothing to do.

4469 * doc/autoconf.texi (testsuite Invocation) < --keywords >:
4470 Update and fix the documentation accordingly.
4471 * tests/autotest.at (Keywords): Renamed to..
4472 (Keywords and ranges): .. this. Extended to make sure negated
4473 keywords, keywords taken from AT_SETUP arguments, and numeric
4474 test ranges work, and that matching is case-insensitive.

4491 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If we cannot enable C99
4492 nor C89 mode, set `$ac_cv_prog_cc_stdc' to `no' instead of
4493 trying to execute the command `no'.
4495 * lib/autoconf/lang.m4 (AC_LANG_CONFTEST): AC_DEFUN this, not
4496 m4_define, so that the requirements of `AC_INCLUDES_DEFAULT' are
4497 expanded outside.
4499 * doc/autoconf.texi (autoconf Invocation): Fix typos in trace
4500 example. Do not emphasize `$%', it is hardly new and special.
4501 Reported by Edouard Bechetoille <ebecheto@ens-lyon.fr>.
4503 * doc/autoconf.texi (Limitations of Usual Tools): Document
4504 OpenBSD and traditional `grep' failure to handle multiple

4524 Use more modern terminology for which standard is what.
4525 (AC_PROG_CC): Mention gcc first, and remove obsolete references to egcs
4526 and to ansi2knr.

4531 the obsolescent AC_HEADER_STDC.
4532 (AC_FOO_IFELSE vs AC_TRY_FOO): Don't use #error; test programs
4533 can't rely on it.
4535 2006-03-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4537 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):

4540 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
4542 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
4543 Require that /lib/cpp include stdio.h correctly. Solaris 10's
4544 doesn't. Problem reported by D'Arcy A MacIsaac and diagnosed by
4545 Ralf Wildenhues.
4547 2006-03-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4549 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): The limit for
4550 HP-UX sed is 99 commands, not 100.
4551 (_AC_OUTPUT_FILES_PREPARE): Do not count the `}' of an
4552 _AC_SUBST_FILES fragment. Separate `{' and `r' commands by
4553 newline for portability.
4554 * tests/torture.at (Torturing config.status): Also test 100
4555 AC_SUBST_FILE invocations. Fix test to actually verify the
4556 AC_CONFIG_FILES output.

5036 (which belong to Xt, not X itself). See Debian bug 327655.
5037 * NEWS: Mention this.
5039 2005-09-07 Stepan Kasal <kasal@ucw.cz>
5041 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
5043 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
5045 * config/move-if-change: Don't output "$2 is unchanged";
5046 suggested by Ben Elliston. Handle weird characters correctly.
5048 2005-09-06 Stepan Kasal <kasal@ucw.cz>
5050 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
5051 calls, so that the final expansion of this macro is shorter.
5052 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
5053 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
5054 the cleanup there. Use AS_VAR_* macros, to be more general.
5055 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
5057 * lib/autoconf/general.m4: Use AS_IF where appropriate.
5059 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
5061 2005-09-01 Stepan Kasal <kasal@ucw.cz>
5063 * doc/autoconf.texi (Configuration Headers): Add an index entry
5064 for AH_HEADER.
5066 2005-08-26 Pavel Roskin <proski@gnu.org>
5068 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
5069 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
5070 running xmkmf.
5072 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
5074 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
5075 The previous patch didn't work, so try a better one.
5077 2005-08-26 Stepan Kasal <kasal@ucw.cz>
5079 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
5080 in the example. Reported by Bruno Haible.
5081 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
5082 "if $undefined_var;" succeeds with my shell.
5084 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
5085 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
5086 but change the m4_divert_text to m4_divert_once.
5088 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
5090 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
5091 Work around bug in Solaris /usr/xpg4/bin/awk.
5092 The bug is present in at least Solaris 8 through 10.
5094 2005-08-24 Stepan Kasal <kasal@ucw.cz>
5096 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
5097 some evil values and relying on the fact that $* concatenates the
5098 parameters by the first character from IFS.
5100 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5101 Stepan Kasal <kasal@ucw.cz>
5103 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
5104 first header appears, define AH_HEADER.
5105 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
5106 Update limitations about when to call AC_CONFIG_HEADERS.
5107 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
5108 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
5109 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
5110 ``Configuration Actions''; fix their index entries.
5112 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
5113 options correctly. Process N-M as M-N if M is smaller than N.
5114 Process ranges correctly so that N-N will run only N.
5115 Sort and uniquify the tests that will be run. If there is more
5116 than one test, reinsert the banners for the tests.
5117 * tests/autotest.at (Keywords): Unmark XFAIL.
5119 2005-08-23 Stepan Kasal <kasal@ucw.cz>
5121 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
5122 before passing the macro name to AH_TEMPLATE.
5124 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
5125 now opens log after option processing; in particular, --version
5126 and --help do not touch config.log.
5128 * Makefile.maint: Revert the change from 2005-08-12.
5130 2005-08-22 Stepan Kasal <kasal@ucw.cz>
5132 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
5133 common code to...
5134 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.

5138 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
5139 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
5140 Language cleanup.
5142 * doc/autoconf.texi (Defining Symbols, Changed Results):
5143 Prepend to LIBS, not append, in examples.
5145 2005-08-16 Stepan Kasal <kasal@ucw.cz>
5147 When building in place, set srcdir="."; suggested by Tim Van Holder.
5149 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
5150 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
5151 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
5152 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
5153 does not mean "no --srcdir option".
5155 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5157 * tests/autoscan.at (autoscan): New file.
5158 * tests/suite.at: Use it.
5159 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
5160 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
5162 * tests/autotest.at (Keywords): Test keywords combinations.
5164 2005-08-12 Stepan Kasal <kasal@ucw.cz>
5166 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
5167 add "2>&1"; gzip 1.2.4 prints help on stderr.
5169 2005-07-27 Stepan Kasal <kasal@ucw.cz>
5171 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
5172 was pushdef'ed twice while popped only once. Push it only once.
5173 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
5175 2005-07-26 Stepan Kasal <kasal@ucw.cz>
5177 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

5182 * Makefile.maint: Update from Bison.
5184 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
5185 "<tab>" in comment, so that the point is understandable.
5187 2005-07-25 Stepan Kasal <kasal@ucw.cz>
5189 Rewrite substantial part of lib/autoconf/status.m4.
5190 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
5191 and CONFIG_COMMANDS are not processed in four separate loops.
5192 Instead, there is one main loop. This alows that the common code
5193 is expanded only once, thus config.status (and configure) is smaller.
5195 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
5196 the AC_LIST_FILES and cousins macros are no longer used.
5198 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
5199 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
5200 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
5201 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
5202 contain the initialization, nor the for loop, nor the associated
5203 commands; all these go to ...
5204 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
5205 _AC_OUTPUT_CONFIG_STATUS.
5206 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
5207 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
5208 (_AC_OUTPUT_FILE): The creation of the sed script ...
5209 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
5210 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
5211 _AC_OUTPUT_MAIN_LOOP.
5212 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
5213 _AC_CONFIG_COMMANDS): Use ...
5214 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
5215 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
5216 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
5217 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
5218 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
5219 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
5220 ... new macros.
5221 (_AC_CONFIG_UNIQUE): Update.
5222 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
5223 Replaced by this ...
5224 (_AC_LIST_TAGS): ... new common macro.
5225 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
5226 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
5227 (_AC_LIST_TAG_COMMANDS): ... new common macro.
5228 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
5229 this didn't belong to the `config commands' section.
5230 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
5231 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
5232 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
5233 to the `config commands' section either.
5234 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
5235 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
5237 ... and many changes to the comments nearby.
5239 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
5240 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
5241 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5242 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
5243 (#define header templates): The comment at the top of the generated
5244 header now includes the name(s) of the source file(s).
5246 Several unrelated small changes:
5248 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
5249 parameter to AC_DIAGNOSE.
5250 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
5251 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
5252 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
5253 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
5254 with AU::AC_OUTPUT.
5255 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
5256 in AC_OUTPUT doesn't double-quote it either.
5257 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
5258 parameters.
5260 2005-07-10 Stepan Kasal <kasal@ucw.cz>
5262 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
5263 versions of Portland Group compiler produce single- and double-quoted
5264 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
5265 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
5267 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
5269 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
5270 This is a corrected version of yesterday's patch.
5272 2005-07-07 Stepan Kasal <kasal@ucw.cz>
5274 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
5275 path, too; insert a "===" to emphasize the line.
5277 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
5278 ac_cv_build_alias to ac_build_alias.
5279 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
5281 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
5282 change eliminates it. Problem reported by Alexandre Duret-Lutz.
5283 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
5284 (AC_ARG_VAR): ... here.
5285 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
5286 target_alias.
5288 Keep a list of all precious variables and process them with one simple
5289 for loop, instead of expanding all commands, or, OTOH, complicated
5290 processing of output of "set".
5291 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
5292 variable names in new macro...
5293 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
5294 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
5295 a loop to assign all ac_env_* and ac_cv_env_* variables.
5296 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
5297 to INIT_PREPARE.
5298 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
5299 its value to shell variable ac_precious_vars and call
5300 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
5301 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
5302 _AC_ARG_VAR_VALIDATE.
5304 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
5305 and the AC_SUBSTs ...
5306 (AC_INIT): ... here.
5308 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
5309 the ac_subst_files section in config.log.
5311 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
5313 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>
5315 * NEWS: New macro AC_C_TYPEOF.
5316 * doc/autoconf.texi (C Compiler): Document AC_C_TYPEOF.

5318 * tests/c.at (C keywords): Test AC_C_TYPEOF.
5320 Fix problems reported by Nicolas Joly.
5321 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
5322 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
5323 They are generated by the Tru64 v5.1B shell.
5325 2005-07-05 Stepan Kasal <kasal@ucw.cz>
5327 Fix my changes from 2005-07-01; reported by Noah Misch.
5328 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
5329 description, the macro now accepts only a single tag.
5330 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
5332 Fix cases when the varsions of Autoconf and Autotest don't match.
5333 Reported by Noah Misch.
5334 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
5335 at_top_builddir, for compatibility with older autotest.
5336 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
5337 is not set, use at_top_builddir, for compatibility with older
5338 versions of autoconf.
5340 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
5342 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
5343 Problem reported by Patrick Welche.
5345 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
5347 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
5348 sed substitution command, so that we allow | in program prefixes
5349 and program suffixes. (& is a problem anyway; we're not fixing
5350 that here.)
5351 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
5352 configure_input, top_builddir, srcdir, etc.
5353 * lib/autotest/general.m4 (AT_INIT): Likewise, for
5354 PATH_SEPARATOR in AUTOTEST_PATH.
5356 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
5358 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
5359 for loop over config.site files using `set', to allow
5360 directory names containing IFS characters.
5362 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
5364 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
5365 directories with weird names. Apparently some people like living
5366 on the edge. However, improve the test that "pwd" actually does
5367 report a name for the working directory.
5368 * NEWS: Remove the claim that we test for funny chars in dir names.
5370 2005-07-01 Stepan Kasal <kasal@ucw.cz>
5372 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's

5382 about #include <config.h>.
5383 (Generic Functions): Mention the Gnulib project.
5384 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
5386 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
5387 document to output the default config_* lists to config.status.
5388 Don't recognize option --file, if the functionality is not there.
5389 Likewise for --header; moreover, recognize --he and --h as shortcuts
5390 for --help in that case.
5392 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
5393 matches the order of execution. No code changed.
5395 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5397 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for

5405 2005-06-29 Stepan Kasal <kasal@ucw.cz>
5407 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
5408 descriptors to child processes; reported by Norman Gray.

5412 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
5414 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
5415 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
5416 (AC_SUBST): Call it.
5417 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
5418 the directory specific variables; but don't call it for configure_input.
5420 2005-06-28 Derek Price <derek@ximbiot.com>
5422 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
5423 addition.
5425 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
5427 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
5428 directory have inherent problems with special characters like spaces,
5429 due to limitations in Make syntax. Problem reported by Alexandre
5430 Duret-Lutz.
5431 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
5432 Also, fix Tru64 porting problem with shell patterns,

5443 Fix some more shell quoting problems. Prompted by a bug report
5444 from Justace Clutter.
5445 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
5446 variable into diagnostic. Make the diagnostic an error, not a warning,
5447 because we really don't support spaces and suchlike in dir names.
5448 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
5449 Don't worry about backslashes in srcdir; it can't happen now.
5450 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
5451 Simplify ac_optarg handling.
5452 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

5459 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
5460 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
5462 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
5463 that '\|' is not allowed in BREs; recommend using newline separated
5464 list of patterns instead of multiple -e options.
5466 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
5468 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.
5470 2005-06-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5472 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
5474 2005-06-21 Stepan Kasal <kasal@ucw.cz>
5476 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
5477 b, t, r, w commands require single space, while : cannot have any.
5478 (Special Shell Variables): Fix sed code this in the example.
5479 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
5480 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
5482 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
5483 expand to the empty list. Don't use two pairs of m4_changequote,
5484 it's not necessary.
5486 2005-06-20 Derek Price <derek@ximbiot.com>

5490 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
5492 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
5493 * doc/autoconf.texi:
5494 Don't mention Solaris versions so much, if a
5495 problem is common to all extant versions of Solaris. Say "SunOS
5496 4" instead of "SunOS" for SunOS 4.
5497 (awk): Mention more of the limitations of traditional Awk.
5498 (cat): Don't talk about cat -v.

5503 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
5504 but the implementation is entirely different and is designed
5505 to be compatible with glibc strverscmp.
5506 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
5508 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
5509 on Mac OS X 10.4 reported by Peter O'Gorman in:
5510 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
5511 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):

5520 as per POSIX.
5521 * lib/m4sugar/m4sh.m4: Likewise.
5522 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
5523 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
5525 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
5526 (.x.1): Ignore the time stamp in the .TH line when deciding whether
5527 to update the man page. That way, we don't have to check in new
5528 man pages every month.
5530 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
5531 quotes and backslashes. Patch from Derek Price.

5540 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
5541 -u, since it outputs chatter if the input files are the same.
5542 Problem reported by Ralf Menzel.
5544 2005-06-08 Derek Price <derek@ximbiot.com>
5546 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
5547 renaming them since they are about to be redefined anyhow.
5549 2005-06-08 Derek Price <derek@ximbiot.com>
5551 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
5552 redefined M4 macros to this node. Document m4_include & m4_sinclude.
5553 Move m4_undefine to alphabetical order.
5555 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
5557 * README: Recommend GNU M4 1.4.3 or later.
5558 * doc/autoconf.texi (Introduction): Likewise.
5559 Reword to avoid some formatting glitches.
5560 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
5561 Clarify explanation of HP compiler bug.
5562 Redo example output tp match current CVS snapshot.
5563 Use @example.org in email addresses when the examples
5564 might get inadvertently cut-and-pasted into user code.
5565 Remove example of autom4te usage that doesn't seem to work now.
5566 Use modern AC_INIT (except when the example is meant to be
5567 shown with Autoconf 2.13).
5568 Update ksh info for Solaris 9 and later.
5569 KB -> kB.
5570 Modernize description of Automake versions a bit.
5571 Don't claim a future version of Autoconf is near.

5574 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5576 * doc/autoconf.texi: Add [] to examples, so that the manual
5577 follows its own advice about quoting better.
5578 Reword to avoid some formatting glitches.
5579 * doc/installt.exi: Reword to avoid some formatting glitches.
5581 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
5582 Tru64 ksh pattern matching bug. Reported against Libtool by
5583 Albert Chin <libtool@mlists.thewrittenword.com> and
5584 Nicolas Joly <njoly@pasteur.fr>.
5586 2005-06-06 Stepan Kasal <kasal@ucw.cz>
5588 m4_cdr of one-member list was [[]] (one-member list containing an
5589 empty string) instead of [] (an empty list. Callers were skewed to
5590 match this misbehaviour. As a consequence of this:
5591 - m4_foreach([x], [], [foo]) expanded to `foo', while
5592 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
5593 This bug has been fixed:
5595 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
5596 expand to an empty string; print error msg if called without
5597 an argument list.
5598 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
5599 misbehaviour; handle [] and [[]] correctly.
5601 2005-06-06 Stepan Kasal <kasal@ucw.cz>
5603 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

5605 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
5607 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
5609 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
5610 swallow records with more than 99 fields.
5611 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
5612 parse the long line.
5614 2005-06-04 Stepan Kasal <kasal@ucw.cz>
5616 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
5617 swallow literals longer than 399. Reported by Ralf Wildenhues.
5618 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
5619 to workaround this limitation.
5621 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
5623 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
5624 to gfortran, and make these the first two compiler names
5625 checked (following the general autoconf preference for gcc).
5627 2005-06-03 Stepan Kasal <kasal@ucw.cz>
5629 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
5630 (DISTCLEANFILES): Remove $(check_SCRIPTS).
5631 (testsuite): Make sure autotest.m4f is up-to-date before using it.
5633 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
5635 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
5636 expression of unbounded size when processing the --list
5637 option. This runs afoul of a limit of 399 bytes per regular
5638 expression on AIX. Problem reported by Ralf Wildenhues.
5640 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
5642 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
5643 * doc/autoconf.texi (Particular Headers): Reword example
5644 for multiline stdbool replacement.
5645 (Setting Output Variables): Reword text a bit. Don't
5646 give all the details about |#_!!_#|.
5647 Reword description of line replacement.
5649 2005-05-31 Dan Manthey <dan_manthey@partech.com>
5651 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
5652 now contain newlines, and substituted files must be referenced on
5653 a line alone; the sed scripts to substitute them are now very
5654 different.
5655 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
5656 commands can be put in a sed script portably.
5657 * doc/autoconf.texi (Setting Output Variables): Document above
5658 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
5659 use of multiline substitution.

5669 * tests/local.at: Don't attempt to check for negated character
5670 classes in shell scripts. The test was too brittle.
5672 2005-05-25 Stepan Kasal <kasal@ucw.cz>
5674 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
5675 * doc/autoconf.texi (Limitations of Builtins): Document this
5676 limitation.
5678 2005-05-24 Stepan Kasal <kasal@ucw.cz>
5680 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
5681 common code; used in many places in the tree.

5688 messages when ac_unique_file is not found.
5689 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
5690 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
5691 commands, for consistency with AC_MSG_ERROR and such.
5693 * bin/autoconf.as: Make more use of "shift 2" in option processing.

5703 2005-05-20 Stepan Kasal <kasal@ucw.cz>
5705 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
5706 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
5707 (ac_top_builddir): ... this ...
5708 (ac_top_build_prefix): ... to this; the old name is also kept, for
5709 backward compatibility.
5710 (ac_top_builddir_sub): New variable, without the trailing slash,
5711 always nonempty.
5712 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
5713 * doc/autoconf.texi (Configuration Actions): Rename
5714 ac_top_builddir to ac_top_build_prefix.
5715 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

5722 of confdefs.h .
5724 2005-05-17 Stepan Kasal <kasal@ucw.cz>
5726 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
5727 argument to m4_foreach. I guess it was necessary in the past,
5728 but I think it's a no-op now.
5730 2005-05-17 Stepan Kasal <kasal@ucw.cz>
5732 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
5733 ``cat <<_ACEOF'' commands to one.
5734 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
5735 * lib/autoconf/status.m4: On various places, use expr instead of
5736 ``echo|sed.''
5737 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
5738 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
5739 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
5740 a range.
5741 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for

5747 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
5748 as on 2005-05-02.
5749 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
5750 Mention LIBOBJDIR.

5813 Also, throughout this document, be more careful about white space.
5814 "blank", "white space", and "space" all have different meanings
5815 and we should be careful to say what we mean.

5876 * lib/autoconf/functions.m4
5877 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):

5879 for you.
5881 2005-04-19 Stepan Kasal <kasal@ucw.cz>

5935 newline, or "\".
5936 * doc/autoconf.texi (Installation Directory Variables): Allow
5937 "," in file names. Do not use \@; it's not a portable regexp.
5938 * bin/Makefile.am (edit): Likewise.
5939 * lib/Makefile.am (edit): Likewise.
5940 * tests/Makefile.am (edit): Likewise.
5941 * tests/semantics.at: Likewise.

5945 * doc/autoconf.texi (File System Conventions): Warn about
5946 unportable file names.
5947 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
5948 (AC_INIT): Use it.
5949 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
5950 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
5951 ac_pwd, and quote srcdir.
5952 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
5954 * doc/autoconf.texi: Fix some systematic formatting problems.
5955 ".)" needs a following @: if not at the end of a sentence, and
5956 similarly for "!)". "etc." should be preceded by a comma.
5957 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
5959 2005-03-22 Bruno Haible <bruno@clisp.org>
5961 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
5962 argument is often called 'build-aux'.
5964 2005-03-07 Stepan Kasal <kasal@ucw.cz>
5966 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
5967 macro AC_TRY_LINK is obsolete.
5968 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
5969 `AC_CONFIG_FILES'.
5971 2005-02-24 Stepan Kasal <kasal@ucw.cz>
5973 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
5974 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
5975 from a Common Lisp's `cl'.
5976 (AC_PROG_CXX): Behave according to the documentation: don't
5977 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
5978 make the variable CCC precious; use `cl.exe', not `cl'.
5980 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5981 Alexandre Duret-Lutz <adl@gnu.org>
5983 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
5984 /dev/null, as "configure" shouldn't read stdin, and this insulates
5985 us from problems (e.g., when testing for "cl"). Also, do this
5986 redirection before invoking "hostname" or "uname", and keep the
5987 original input stream available via...
5988 (AS_ORIGINAL_STDIN_FD): ... this new macro.
5989 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
5990 bother with "</dev/null" since it's now done at the top of
5991 'configure'.
5992 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
5993 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

5999 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6001 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
6002 newline if neither \c nor -n work, as that would output two
6003 newlines. Prefer -n to \c. Reported by Stepan Kasal.
6005 2005-02-12 Stepan Kasal <kasal@ucw.cz>
6007 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
6008 This causes that any required macros inside will get before the if.
6009 * doc/autoconf.texi (autom4te.cache): A typo.
6011 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
6013 Undo previous change, except keep the change to
6014 lib/autoconf/programs.m4 that replaced grep with shell
6015 pattern-matching. This is because net-snmp configure reads stdin.
6016 Reported by Noah Misch.
6018 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
6020 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
6021 from /dev/null, as "configure" shouldn't read stdin, and this
6022 insulates us from problems (e.g., when testing for "cl").
6023 Suggested by Alexandre Duret-Lutz. Also, do this redirection
6024 before invoking "hostname" or "uname".
6025 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6026 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
6027 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
6028 "</dev/null" since it's now done at the top of 'configure'.
6029 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6030 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
6031 Also, replace grep with shell pattern-matching, to save a process.
6033 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
6035 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6036 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
6037 avoid thinking that Allegro Common Lisp's "cl" command is a C++
6038 compiler.
6040 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
6042 * doc/autoconf.texi (Limitations of Usual Tools): Document that
6043 grep -q isn't portable. Improve grep -s explanation.
6044 Problem reported by Dan Manthey.
6046 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
6048 * doc/autoconf.texi (Special Shell Variables): Clarify
6049 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
6051 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
6053 * doc/autoconf.texi: Use @acronym for DJGPP.
6054 Fix some @code's that should have been @env's, and vice versa.
6055 Sort environment variable names.
6056 Mention that shells no longer inherit IFS.
6057 Don't recommend PATH_SEPARATOR=';' so strongly.
6058 Mention that $RANDOM might expand to the empty string.
6059 "symlink" and "soft link" -> "symbolic link".
6060 Improve mktemp description (reported by Bruno Haible).
6062 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
6064 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
6065 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
6066 Likewise.
6067 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
6068 Likewise.
6070 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
6072 * NEWS: Mention AT_COPYRIGHT.
6074 * tests/local.at (AT_CMP): Use diff directly on input files rather
6075 than copying them.
6077 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
6078 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
6080 2005-02-04 Noah Misch <noah@cs.caltech.edu>
6081 and Paul Eggert <eggert@cs.ucla.edu>

6090 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
6091 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
6092 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
6093 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
6094 (Standard regular expressions): New test.
6095 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
6096 excess test name quoting.
6097 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
6098 CPPFLAGS to `configure' instead of setting it in `configure'.
6100 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
6101 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
6102 on some platforms.
6104 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
6105 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

6108 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.

6113 * tests/c.at (Extensions): Do not exit early.

6133 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
6135 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
6136 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
6138 Try not to generated lines of unlimited length, as POSIX places a
6139 2047-byte limit on line length of portable text files.
6140 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
6141 Use newline as a separator, not space.
6142 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
6143 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
6144 space.
6146 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6148 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
6149 as_func_*. Add test to check whether positional parameters
6150 are restored after function return.
6152 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
6154 * doc/autoconf.texi (Special Shell Variables): Mention _,
6155 BIN_SH, DUALCASE. Say that variables other than "status" are safe
6156 if they contain a lower-case letter. The DUALCASE problem was
6157 reported by Ralf Wildenhues.
6159 * bin/autoconf.as: Don't exit with status 0 after write failure
6160 with --help or --version.
6161 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

6167 Unicos 9 sed limitations.
6168 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
6169 to get the option-enhanced interface on older Crays. Try ftn for
6170 Fortran 95 (newer Crays).
6172 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
6174 * man/Makefile.am (.x.1): Go back to the simple solution, but take
6175 care to echo the commands, so the user knows what's going on.
6176 Modified from a suggestion by Stepan Kasal.
6178 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

6185 * doc/install.texi (Defining Variables): Likewise.
6186 Based on a proposed patch by Ralf Wildenhues.
6188 * man/Makefile.am (.x.1): Make sure the required generated files
6189 are up to date. Problem and original solution proposed by Stepan Kasal.
6190 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
6191 implicit-man-prerequisites): New rules, used by the above.

6197 2005-01-29 Stepan Kasal <kasal@ucw.cz>
6199 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
6200 Update the long comment explaining it.
6202 m4_require no longer writes an ``is required by'' line to the
6203 execution stack. It contains only one bit of non-redundant
6204 information: that the macro was required, not called. And even
6205 this bit is useless in most situations: have you ever met a macro
6206 which both calls and requires the same macro?
6208 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
6209 (_m4_defun_pro_outer): ... only via this macro, for the outermost
6210 macro.
6211 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
6212 (m4_expansion_stack_pop): Remove the misplaced comment.
6213 (m4_require): Don't put the ``is required by'' line to the
6214 execution stack; slightly improve the out-of-a-defun error message.
6215 (_m4_divert_grow): New macro, counter for the temporary diversions.
6216 (_m4_require_call): Use it.
6217 * tests/m4sugar.at (m4_require): Expect output without the
6218 ``is required by'' messages.
6220 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
6222 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
6223 rather than x for expr.
6225 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
6226 this is safe.
6227 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
6228 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

6238 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
6239 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
6240 from masters, so that FileUtils.pm's update_file provide --force
6241 support.
6242 * bin/autoheader.in: Pass $force to update_file so that
6243 config.h.in is always recreated when --force.
6245 2005-01-24 Stepan Kasal <kasal@ucw.cz>
6247 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
6249 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
6251 * doc/autoconf.texi (Limitations of Builtins): Clarify that
6252 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
6254 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
6256 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
6257 Warn about newline stripping in `` and $(). Update Solaris
6258 version to 9.
6259 (Limitations of Builtins): Use expr "X...", not expr "x...", as
6260 X insulates us from future changes to Posix.
6261 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
6262 stripping.
6264 2005-01-19 Stepan Kasal <kasal@ucw.cz>
6266 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
6267 you cannot use AC_DEFINE to define macros containing `[' or `]'.
6269 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
6271 * doc/autoconf.texi (Limitations of Usual Tools): Document bug
6272 in Solaris 8 join. Problem reported by Tomohiro Suzuki on

6279 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
6281 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C)): Declare longval and
6282 ulongval to be static, to avoid unwanted GCC warning. Problem
6283 reported by Michael Jennings via Daniel Reed; see
6284 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
6286 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
6288 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
6289 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update
6290 datadir, infodir, and mandir. Adjust argument parsing code.
6291 (_AC_INIT_HELP): Update help text.

6293 new variables.
6295 2005-01-04 Noah Misch <noah@cs.caltech.edu>
6297 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
6298 not seem to work, assume it does set $(MAKE).
6299 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
6301 2005-01-03 Stepan Kasal <kasal@ucw.cz>
6303 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.

6309 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
6310 (_m4_divert_n_stack): New macro; the expansion is
6311 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
6312 otherwise.
6313 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
6314 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
6315 stored in _m4_divert_diversion or _m4_divert_dump.
6316 (m4_divert_pop): When the parameter is given, compare the symbolic
6317 name with the last diversion pushed on the stack. Previously, the
6318 current diversion was compared with the numeric value of the
6319 diversion given as the parameter.
6320 (m4_require): If the macro hasn't been expanded yet, call ...
6321 (_m4_require_call): this new macro.
6323 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6325 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_ARG_VAR_VALIDATE):

6354 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
6355 signals that the package uses Automake; a `Makefile.am' is typical but
6356 not essential. Reported by Magnus Therning.
6357 * tests/torture.at (autoreconf.): New banner.
6358 (autoreconf and non-AC configure): Rename to `Non-Autoconf
6359 AC_CONFIG_SUBDIRS'.

6628 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
6629 "char c = '\200';" rather than "char c = 0x80;" as the

6631 overflow on signed char hosts.

6634 to -qlanglvl=ansi. We don't want to disable extensions.

6747 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
6748 "/usr/include", clear ac_x_includes instead of leaving it as "no"

6839 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
6841 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
6843 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
6844 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
6845 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
6847 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
6849 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
6850 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
6851 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
6852 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
6853 * lib/autom4te.in (Automake-preselections): Preselect
6854 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
6856 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
6858 * lib/autom4te.in (Automake-preselections): Preselect
6859 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
6860 trace them.
6862 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
6864 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
6865 Tru64.
6866 * doc/autoconf.texi (Shellology): Mention BIN_SH.
6867 Document problem with "`""`" in pdksh POSIX mode.
6869 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
6871 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
6872 with pdksh, too. Problem reported by Patrick Welche via
6873 Gary V. Vaughan.
6874 * doc/autoconf.texi (Shellology): Note that set -o posix is
6875 useful for pkdsh, too.
6877 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
6879 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
6880 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
6881 Don't fail if ENV or BASH_ENV is readonly.
6882 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
6883 etc. are read only. Problem reported by Ludovic Courtes.
6885 2004-06-23 Noah Misch <noah@cs.caltech.edu>
6887 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
6888 zsh, disable GLOB_SUBST to avoid backslash handling problems.
6889 (trivial change)
6891 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
6893 * doc/autoconf.texi (File System Conventions): Warn about
6894 names like "aux". Problem reported by Eric Blake.
6896 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
6897 by zero instead of array size, so that we can use any arithmetic
6898 constant expression (instead of requiring an integer constant
6899 expression). This allows us to test expressions like DBL_MAX <
6900 LDBL_MAX, which didn't conform to the C standard using the old
6901 method.
6902 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
6903 now that we can do floating-point tests at compile time.
6905 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
6907 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
6908 and LDBL_EPSILON, as the resulting expression isn't an
6909 integer constant expression and violates the C standard.
6910 Problem reported by Nelson H. F. Beebe. Also, check
6911 for "L" suffix, and check that long double doesn't have
6912 worse range or precision than double, that mixed-mode
6913 arithmetic doesn't generate a diagnostic, that double
6914 constants fit in long double.
6916 2004-06-03 Kevin Ryde <user42@zip.com.au>
6918 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
6919 malloc(0) and realloc(NULL,size).
6921 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
6922 Bob Proulx.
6924 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
6926 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
6927 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
6928 by Jim Meyering.
6930 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
6932 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
6933 can be rewritten using if-then-else. Suggested by Bruno Haible.
6935 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
6937 * doc/autoconf.texi (testsuite Scripts): Fix typo.
6938 Problem reported by Stepan Kasal.
6940 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
6942 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
6943 change). Patch reported by Ralf Wildenhues in
6944 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
6946 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
6947 function F exists if the compiler and linker let you compile an
6948 expression like (F != 0). Recent versions of GCC optimize away
6949 the reference to F in that case, since every function address must
6950 be nonzero, so the link succeeds even if F does not exist.
6951 Problem reported by Manu in
6952 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
6954 * doc/autoconf.texi (Systemology): Standardize on the spelling of
6955 "Unix". Many uses changed.
6956 (Limitations of Builtins): Explain better why the ! command isn't
6957 portable.
6959 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
6961 * lib/autom4te.in (Automake-preselections): Preselect
6962 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
6964 2004-05-19 Kevin Ryde <user42@zip.com.au>
6966 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
6967 referencing AC_FUNC_STRERROR_R.
6969 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
6970 note pessimistic assumption when cross compiling.
6972 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
6974 * doc/autoconf.texi (Limitations of Make): Note that BSD make
6975 (until 2004) invoked subcommands with sh -e, contra POSIX.
6976 Reported by Kevin Ryde.
6978 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
6980 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
6981 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
6982 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
6983 `test -f " /usr/bin/grep"', which _always_ failed.
6984 (AC_PROG_SED): Ditto bogus PATH fix.
6985 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
6986 requires that grep correctly supports _multiple_ `-e' options, rather
6987 than stating only that grep should accept `-e'.
6989 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
6991 Port to C99, which requires that 'exit' be declared.
6993 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
6994 to ensure that stdlib.h is included.
6995 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
6996 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
6997 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
6998 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
6999 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
7000 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
7001 when using 'exit' in a test; C99 requires that 'exit' be declared.
7003 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
7005 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
7006 now prefers 'grep' implementations that accept -e.
7007 (Limitations of Usual Tools): Describe problems of traditional
7008 egrep and fgrep with long input lines, and of traditional grep
7009 with -e.
7010 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
7011 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
7012 All callers changed. Append /usr/xpg4/bin to the PATH, for
7013 Solaris.
7014 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
7015 the user with complaints about multiple -e options.
7016 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
7017 Define it with AC_PROG_GREP.
7018 * configure.ac (AC_PROG_GREP): Add.
7019 * lib/freeze.mk (GREP): New macro.
7021 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
7023 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
7024 a possible candidate only after all others fail, rather than
7025 consulting it first. This improves backward compatibility by
7026 better reflecting the way shell selection occurred in previous
7027 versions of Autoconf, and should help to avoid triggering latent
7028 problems in other packages, such as the one in Automake where zsh
7029 is not handled robustly:
7030 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
7031 Although it is not Autoconf's responsibility to work around
7032 problems in Automake, it nevertheless makes sense to avoid
7033 introducing unnecessary incompatibilites.
7035 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
7036 Gary V. Vaughan <gary@gnu.org>
7038 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
7039 how deeply nested we are when a suitable tool is found, set the
7040 ac_path_TOOL_found flag.
7041 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
7042 nested we are in this macro. Break out of all 3 nested loops if
7043 ac_path_TOOL_found is set.
7045 2004-04-21 Gary V. Vaughan <gary@gnu.org>
7047 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
7048 of the _AS_PATH_WALK loop too if GNU flavor is found.
7050 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
7052 * doc/autoconf.texi (Limitations of Make): Update documentation
7053 for `$<'. New entry `Long lines', based on a report from Simon
7054 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
7055 paragraph about DJGPP, based on a mail from Richard Dawe.
7057 2004-04-20 Paul Eggert <eggert@twinsun.com>
7059 * tests/c.at (C keywords): Don't assume that GCC supports
7060 "restrict" and "inline", as sufficiently-old GCC versions do not
7061 (also, GCC configured to be in pedantic C89 mode does not).
7062 Problem reported by Sumit Pandya in:
7063 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
7065 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
7066 consider -g to work if it generates warnings when plain compiles
7067 don't. Problem reported by Braden McDaniel in:
7068 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
7070 * doc/autoconf.texi (Slashes): New section, to document a problem
7071 reported by Jim Meyering in:
7072 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
7074 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
7075 linker output files before linking, to work around IRIX 6 linker bug.
7076 Problem reported by Rainer Orth in:
7077 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
7079 2004-04-20 Gary V. Vaughan <gary@gnu.org>
7081 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
7082 best tool so far counter rely on the tool path variable name to
7083 avoid checks for one tool being affected by the results of running
7084 the length check on a previous tool.
7086 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
7087 match expression argument, as different greps have different
7088 regular expression flavours.
7089 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
7090 literals.
7091 (AC_PROG_EGREP): Pass 'EGREP$'.
7092 (AC_PROG_GREP): Pass 'GREP$'.
7094 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
7096 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
7097 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
7099 2004-03-29 Paul Eggert <eggert@twinsun.com>
7101 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
7102 Types, Specific Compiler Characteristics, System Services,
7103 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
7104 etc. consistently instead of 'long', 'short', 'unsigned' etc.
7105 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
7106 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
7107 Likewise.
7108 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
7109 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
7110 AC_TYPE_OFF_T): Likewise.
7111 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
7112 Likewise.
7114 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
7115 pacify libtool 1.5.2. Fix quoting problems in sed command.
7117 2004-03-28 Paul Eggert <eggert@twinsun.com>
7119 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
7120 now defines HAVE_DECL_TZNAME if it is declared, when
7121 HAVE_STRUCT_TM_TM_ZONE is not defined.
7122 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
7123 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
7124 for HAVE_TZNAME.
7126 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
7128 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
7129 superfluous backslashing of quotes (") in sed expressions;
7130 thanks to Paul Eggert.
7132 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
7134 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
7135 Fortran compiler is ifort, also added pghpf; thanks to Nelson
7136 H. F. Beebe for the bug report.
7138 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
7140 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
7141 quoted -cmdline argument in Portland Group compiler (bug
7142 reported by Jeffrey J. Barteet).
7144 2004-03-25 Kevin Ryde <user42@zip.com.au>
7146 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
7147 (Run Time): ... here, where it's now mentioned.
7149 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
7151 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
7152 inherits from language Autoconf-without-aclocal-m4.
7153 (Customizing autom4te): Adjust example; the cache must now be
7154 disabled for language Autoconf-without-aclocal-m4.
7156 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
7157 Nathanael Nerode <neroden@twcny.rr.com>
7159 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
7160 AC_CHECK_TOOLS): Warn if a cross-tool is found without
7161 a prefix.

7167 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
7168 AC_CHECK_TOOLS.
7169 (Specifying Names): Document the reason for these future
7170 behavioral changes.
7171 * tests/mktests.sh: Do not generate tests for the
7172 new macros.
7173 * NEWS: Document these changes.
7175 * doc/autoconf.texi: Avoid macros with unbraced arguments,
7176 they make TeX hang up.
7178 2004-03-15 Paul Eggert <eggert@bogus.example.com>
7180 * NEWS: New macro AC_CHECK_ALIGNOF.
7181 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
7182 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
7183 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
7184 vowel.
7185 (AC_CHECK_ALIGNOF): New macro.
7186 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
7187 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
7188 those for sizeof.
7190 2004-03-03 Paul Eggert <eggert@twinsun.com>
7192 * bin/Makefile.am (edit): Don't use $< in a context where
7193 POSIX doesn't require support for it. Use $@.in instead.
7194 Problem reported by Anthony N. Frasso in
7195 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
7196 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
7198 2004-02-23 Gary V. Vaughan <gary@gnu.org>
7200 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
7201 from the next generation of Libtool.
7202 * lib/autom4te.in (Autoreconf-preselections): Ditto.
7204 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7206 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
7207 is not always thread-safe. Report from Nathanael Nerode.
7209 2004-02-18 Paul Eggert <eggert@twinsun.com>
7211 Fix a dependencies problem, stemming from a Autoconf 2.59 build
7212 problem on QNX reported by Stephen Rasku in
7213 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
7215 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
7216 $(m4sh_m4f_dependencies); this removes a FIXME.
7217 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
7218 (MAINTAINERCLEANFILES): Split into pieces,
7219 one per related section. Add $(srcdir)/wrapper.in.
7221 2004-02-09 Paul Eggert <eggert@twinsun.com>
7223 * doc/autoconf.texi (Setting Output Variables): Emphasize that
7224 AC_SUBST provides no portable way to escape literal newlines.
7226 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
7227 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
7228 Darwin uses -lcrt2.o and there's little point to cataloging all
7229 the system variants. Partial fix reported by Andreas Waechter in:
7230 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
7231 for bug reported by Nelson H. F. Beebe in:

7239 acobsolete.m4, suggested by Alexandre Duret-Lutz.
7241 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
7243 * bin/autoupdate.in: Define __file__ so that warnings
7244 refer to the correct file.
7245 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
7246 the behavior of the third argument.
7247 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
7248 correctly the behavior of the third argument. Document
7249 what the three macros that AU_DEFUN defines do. Fix
7250 warning message when the third argument includes $0
7251 (reported by Alexandre Duret-Lutz).
7253 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
7254 Eric Sunshine <sunshine@sunshineco.com>
7255 Paul Eggert <eggert@twinsun.com>
7257 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
7258 (AS_INIT): Output shell initialization there. Removed optional
7259 parameter. Expand _AS_SHELL_FN_SPY.
7260 (AS_INIT_WITH_SHELL_FN): Removed.
7261 (_AS_SHELL_FN_SPY): New macro.
7262 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
7263 macros.
7264 (AS_SHELL_SANITIZE): Remove loop to find better shell
7265 and documentation for the parameter.
7266 (_AS_DETECT_BETTER_SHELL): Move it here.
7267 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
7268 (_AS_RUN): Move it here, support testing with eval.
7269 (AS_REQUIRE_SHELL_FN): Require shell functions when
7270 it is used.
7271 (_AS_LINENO_WORKS): Put around braces, we do not
7272 trigger the bash bug anymore.
7273 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
7274 use AS_INIT_WITH_SHELL_FN.
7275 * bin/autoconf.in, tests/wrapper.in: Regenerated.
7277 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
7279 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
7280 * doc/autoconf.texi: Don't say that the third parameter
7281 is broken.
7282 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
7283 (AU_DEFUN): Honor the third parameter, create autoupdate
7284 macros with AU_DEFINE.
7285 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,

7294 * lib/autoconf/status.m4: Remove FIXME.

7305 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

7307 the 2003-05-22 change, which removed the older years from the list.
7308 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
7310 2004-01-27 Gary V. Vaughan <gary@gnu.org>

7315 possible.
7316 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
7317 AC_PROG_GREP.
7318 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
7319 egrep and fgrep respectively if $GREP -E/-F don't work.
7320 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
7321 _AC_PROG_GREP, and AC_PROG_SED.
7322 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
7323 longest input length accepted by a command.
7324 (AC_PROG_SED): Use it.
7325 * doc/autoconf.texi (Particular Programs): Document the changes.
7326 * NEWS: Updated.
7328 2004-01-27 Paul Eggert <eggert@twinsun.com>
7330 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

7332 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
7333 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
7335 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
7336 bin/autoconf.in, config/Makefile.in, config/config.guess,
7337 config/config.sub, config/install-sh, config/mdate-sh,

7352 2004-01-26 Paul Eggert <eggert@twinsun.com>
7354 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
7355 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
7356 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
7357 not <inttypes.h>. Problem reported by Tim Mooney in
7358 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
7359 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
7360 Likewise.
7362 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
7363 otherwise "make check" fails because it forbids cmp (I guess
7364 because cmp treats files as binary on DOS-like systems).
7366 * tests/mktests.sh: Update copyright date to 2004, since some tests
7367 have changed in 2004.
7369 2004-01-23 Gary V. Vaughan <gary@gnu.org>

7372 non-truncating sed or gsed program in PATH.
7373 * tests/acprograms.at: Add it.

7375 * NEWS: Updated.
7377 2004-01-15 Paul Eggert <eggert@twinsun.com>
7379 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
7380 -std1 disables some useful extensions on Tru64. Problem reported
7381 by N. Lichtmaier in
7382 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
7384 2004-01-14 Paul Eggert <eggert@twinsun.com>
7386 * doc/autoconf.texi (Programming in M4sh): Document that
7387 AS_MKDIR_P succeeds if the destination is a symbolic link
7388 to an existing directory.
7389 (Limitations of Usual Tools): Note that mkdir -p might not
7390 succeed on symlinks to directories.
7392 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
7394 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
7395 * bin/autoheader.in: Grammar fix in message.
7396 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
7397 Test for dir before calling mkdir -p. (trivial changes)
7399 2004-01-13 Eric Blake <ebb9@byu.net>
7401 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
7402 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
7404 2004-01-10 Jim Meyering <jim@meyering.net>
7406 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
7408 2004-01-09 Paul Eggert <eggert@twinsun.com>
7410 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
7411 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
7412 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
7413 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
7414 AC_COMPILE_IFELSE, since we now assume our caller invokes
7415 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
7416 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
7417 of AC_RUN_IFELSE; this avoids the warning mentioned above.
7418 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
7420 2004-01-07 Paul Eggert <eggert@twinsun.com>
7422 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
7423 `"'...'"`, as it's confusing (and I suspect it may not work on
7424 some platforms). The code was incorrect anyway, as it assumed
7425 that \$ evaluated to itself in that context. Reported by
7426 Alexandre Duret-Lutz.
7428 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
7430 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
7431 and _LT_AC_TAGCONFIG.

7435 * doc/autoconf.texi (One Macro Call): Fix an incorrect
7436 example, and add more examples. Reported by Eric Sunshine.
7438 2004-01-05 Paul Eggert <eggert@twinsun.com>
7440 * doc/autoconf.texi (Limitations of Usual Tools):
7441 Remove warning against "rm -fr" introduced yesterday; it
7442 was a false alarm.
7444 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
7445 autoscan, autoupdate, ifnames): Don't use chmod -w.
7446 * lib/Makefile.am (autom4te.cfg): Likewise.
7447 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
7448 "chmod -w".

7451 Paolo Bonzini <bonzini@gnu.org>
7453 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
7454 by doing lineno substitution only on lines containing "$LINENO".
7456 2004-01-04 Paul Eggert <eggert@twinsun.com>
7458 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
7459 Use "rm -f" to remove conftest.sed, not plain "rm".
7460 Bug reported by David Relson in
7461 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
7463 * Makefile.am (autom4te-update):
7464 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
7465 * Makefile.maint (my-distcheck, do-po-update): Likewise.
7466 * doc/autoconf.texi (Guidelines): Likewise.
7467 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

7472 * tests/Makefile.am (clean-local): Likewise.
7473 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
7474 srcdir): Likewise.
7475 * doc/autoconf.texi (Limitations of Usual Tools):
7476 Warn against "rm -fr".
7478 2004-01-03 Paul Eggert <eggert@twinsun.com>
7480 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
7481 -c -o might not work. From a suggestion by Kevin Ryde.
7482 (C Compiler, Generating Sources, Limitations
7483 of Usual Tools, Limitations of Make, Making testsuite Scripts):
7484 Don't put '-o' after non-options, as POSIX doesn't allow this.
7485 Mention that cc's name might be gcc or c89 or whatever.
7487 2004-01-04 Kevin Ryde <user42@zip.com.au>
7489 * doc/autoconf.texi: Add various further index entries.
7491 2003-12-29 Paul Eggert <eggert@twinsun.com>
7493 * bin/autoreconf.in (autoreconf_current_directory):
7494 Fix typo: mkdir without umask arg.
7496 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
7498 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
7499 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
7500 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
7501 explanation clearer.
7503 2003-12-24 Andreas Schwab <schwab@suse.de>
7505 * doc/autoconf.texi (Default Includes): Fix misspelling of
7506 AC_INCLUDES_DEFAULT.

7510 * configure.ac: Test if sh -n works.
7511 * configure: Regenerate.
7512 * tests/atlocal.in: Store the result here.
7513 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
7514 tools.at, looking in atlocal's ac_cv_sh_n_works instead
7515 of explicitly testing.
7516 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
7517 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
7518 * tests/tools.at (Syntax of the shell scripts): Simplify
7519 using AT_CHECK_SHELL_SYNTAX.

7532 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
7533 Extracted from AS_SHELL_SANITIZE.
7534 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
7535 macros.
7536 (AS_SHELL_SANITIZE): Move reinvocation code from
7537 _AS_LINENO_WORKS, use it to find out if shell
7538 functions work.
7539 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
7540 does not work.
7541 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
7542 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

7556 them on the fly.
7558 2003-11-24 Akim Demaille <akim@epita.fr>
7560 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

7588 parameter of AU_DEFUN.

7603 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
7604 than $target since the latter is not usual, add guidelines on when to

7686 2003-10-28 Akim Demaille <akim@epita.fr>
7688 * Makefile.cfg (local_updates, executable-update): Tweak to be

7750 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug in
7751 pdksh 5.2.14. Bug reported by Ralf Corsepius.
7752 * doc/autoconf.texi (Shellology): Mention the Korn shell and pdksh.
7753 Mention /usr/dt/bin/dtksh on Solaris.

7755 (Parentheses): New section.
7757 2003-10-15 Kevin Ryde <user42@zip.com.au>
7759 * doc/autoconf.texi (Function Portability): Add @prindex for exit.
7760 Add putenv and unsetenv. Add sysconf _SC_PAGE_SIZE.
7762 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
7764 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
7765 cross test.
7767 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
7769 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
7770 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
7772 2003-10-10 Andreas Schwab <schwab@suse.de>
7774 * bin/autoheader.in: Avoid empty first line in --version and
7775 --help output.
7776 * bin/ifnames.in: Likewise.
7778 2003-10-09 Paul Eggert <eggert@twinsun.com>
7780 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
7781 Issue a more-informative diagnostic.
7782 Problems reported by Eric Sunshine.
7784 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
7786 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
7787 -mGLOB_options_string stuff for Intel ifc, which can cause
7788 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
7789 pattern-matching instead of grep.
7791 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
7793 * doc/autoconf.texi: Document new FC Fortran macros.
7795 2003-10-08 Gary V. Vaughan <gary@gnu.org>
7797 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
7798 that future autopoint/aclocal/automake/autoreconf will be able
7799 to trace to find where to install local m4 macros.
7800 * doc/autoconf.texi (Input): Document it.
7801 * NEWS: Updated.
7803 2003-10-06 Gary V. Vaughan <gary@gnu.org>
7805 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
7806 -lcrtbegin.o to list of ignored flags and fix underquoting of
7807 -lcrt[01].o.
7809 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
7811 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
7812 cache variable instead of $G77 to decide whether to include -O2,
7813 since $G77 is specific to Fortran 77.
7815 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7817 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
7818 free" flag. Re-order flags tested into rough order of popularity.
7820 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7822 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
7823 arguments so that it can be used with syntax identical to
7824 AC_PROG_F77, and so that we can more easily decide to
7825 remove/deprecate the DIALECT optional argument in the future if it
7826 proves troublesome.
7827 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
7828 non-freeform-supporting compilers. Document freeform flags.
7830 2003-10-03 Akim Demaille <akim@epita.fr>
7832 * configure.ac: Look for emacs, not macs.
7833 Reported by Eric Sunshine.
7835 2003-10-03 Akim Demaille <akim@epita.fr>
7837 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
7838 * bin/autoreconf.in (autoreconf_current_directory): Create the
7839 AUX_DIR if needed, for sake of automake --add-missing etc.
7840 Suggested by Alexandre Duret-Lutz.
7842 2003-10-03 Akim Demaille <akim@epita.fr>
7844 * configure.ac: Quotation and formatting changes.
7845 (EMACS): Don't set it if it is not recent enough to support
7846 autoconf-mode.el.
7847 From Eric Sunshine.
7849 2003-10-02 Akim Demaille <akim@epita.fr>
7851 * bin/ifnames.in (&scan_file): Skip C++ comments.

7863 2003-09-30 Paul Eggert <eggert@twinsun.com>
7865 * lib/Autom4te/XFile.pm: Use Errno.
7866 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
7867 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
7869 2003-09-30 Akim Demaille <akim@epita.fr>
7871 * config/announce-gen (&print_news_deltas): Extracted from...
7872 (&print_changelog_deltas): here.
7873 (&news_file): Rename as...
7874 (@news_file): this.
7876 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
7878 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
7879 have been created when invoking the compiler.
7880 * tests/fortran.at (GNU Fortran 77): Quote $G77.

7884 Version 2.57e.
7886 * config/mkinstalldirs: Upgrade.
7888 2003-09-28 Paul Eggert <eggert@twinsun.com>
7890 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
7891 Problem reported by Lars J. Aas in
7892 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
7893 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
7894 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
7895 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
7897 2003-09-26 Akim Demaille <akim@epita.fr>
7899 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
7900 directory for AC_CONFIG_COMMANDS' first argument exists.
7901 This makes valid the invocation of _AC_SRCPATH that follows.
7902 Reported by Eric Sunshine.
7903 * doc/autoconf.texi (Configuration Commands): Adjust.
7905 2003-09-26 Akim Demaille <akim@epita.fr>
7907 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
7908 Reported by Ralf Corsepius.
7910 2003-09-26 Akim Demaille <akim@epita.fr>
7912 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
7913 arguments.
7914 Actually, use AU_ALIAS.
7915 From Bruno Haible.
7917 2003-09-26 Paul Eggert <eggert@twinsun.com>
7919 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
7920 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
7921 Problem reported by Eric Sunshine in:
7922 http://mail.gnu.org/archive/html/autoconf-patches/2002-12/msg00014.html
7924 2003-09-26 Akim Demaille <akim@epita.fr>
7926 The test suite are sometimes assigning timings incorrectly.
7927 Reported by Henk Krus.
7928 Diagnosed by Nicolas Joly.
7930 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
7931 AT_help_all.
7932 Instead of making AT_help a sequence of assignments to grow
7933 $at_help_all, just make AT_help_all be the growing contents of
7934 $at_help_all, and make a single assignment in...
7935 (AT_INIT): here.
7936 (at_times_skip): Flip the meaning and rename as...
7937 (at_times_p): this.
7938 (AT_INIT): When summarizing the test that ran, remove
7939 $at_times_file after use, and check it is present before trying to
7940 use it.
7942 2003-09-25 Akim Demaille <akim@epita.fr>
7944 Version 2.57d.
7946 * bin/Makefile.am (edit): Handle '@configure_input@'.
7947 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
7948 (ifnames): chmod -w.
7949 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
7950 executables, not bin/ executables! Otherwise all the magic needed
7951 to find non installed files is turned off. This caused a failure
7952 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
7953 as found in its environment (sent by tests/autoreconf): pointing
7954 to bin/autom4te that could not find its files.
7955 * tests/mktests.sh: Force the replacement of generated files, for
7956 the sake of "mv" program that are interactive when overwriting a
7957 -w file.
7958 * config/install-sh: Upgrade from CVS Automake.
7960 2003-09-23 Paul Eggert <eggert@twinsun.com>
7962 * doc/autoconf.texi (Limitations of Builtins): Document test -h
7963 versus test -L issues.
7965 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
7966 Paul Eggert <eggert@twinsun.com>
7968 Trivial change to support GCC's configuration procedure.
7969 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
7970 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
7971 about inconsistency if the preprocessor is set to give errors for
7972 any warning.
7973 * doc/autoconf.texi (C Compiler Characteristics): Document this.
7975 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
7977 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
7978 and XFile.pm from Automake.

7985 2003-09-12 Akim Demaille <akim@epita.fr>
7987 * config/config.guess, config/config.sub, config/missing,
7988 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
7989 from masters.
7991 2003-09-12 Akim Demaille <akim@epita.fr>
7993 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
7994 not asm/types.h.
7996 2003-09-11 Akim Demaille <akim@epita.fr>
7998 * doc/autoconf.texi (Header Portability): linux/random.h.
7999 From Peter Hendrickson.
8001 2003-09-10 Akim Demaille <akim@epita.fr>
8003 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
8004 willing to edit the output files.
8006 2003-09-10 Akim Demaille <akim@epita.fr>
8008 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
8009 and AC_FC_FREEFORM.
8010 * tests/mktests.sh: Skip AC_FC_SRCEXT.
8011 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
8013 2003-09-09 Akim Demaille <akim@epita.fr>
8015 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
8016 Reported by Gary Vaughan.

8019 2003-09-09 Akim Demaille <akim@epita.fr>
8021 * lib/Autom4te/FileUtils.pm (&update_file): Be sure not to leave
8022 trailing files.
8024 2003-09-07 Paul Eggert <eggert@twinsun.com>
8026 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
8027 Improve the accuracy of the wording about obsolescence.
8028 From a suggestion by Ian Lance Taylor in
8029 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
8031 2003-09-05 Paul Eggert <eggert@twinsun.com>
8033 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
8034 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
8036 2003-09-04 Akim Demaille <akim@epita.fr>
8038 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
8039 AC_FUNC_WAIT3.
8041 2003-09-04 Akim Demaille <akim@epita.fr>
8043 * bin/autom4te.in: Use &fatal where more appropriate than &error.
8044 (freeze): When exiting, use $exit_code.
8045 * lib/autoconf/fortran.m4: Comment changes.
8047 2003-09-04 Akim Demaille <akim@epita.fr>
8049 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
8051 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
8053 Add support for newer Fortran dialects. The F77 interface is
8054 unchanged, and continues to support Fortran 77. New FC macros
8055 correspond to all the old F77 macros, with output variables FC,
8056 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
8057 available dialect, but older dialects can be specified. There are
8058 new macros AC_FC_SRCEXT to set the source extension, and
8059 AC_FC_FREEFORM to accept free-form source files.
8061 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
8062 New macros.
8063 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
8064 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
8065 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
8066 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

8074 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
8075 AC_FC_SRCEXT, AC_FC_FREEFORM):
8076 New macros.
8077 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
8078 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
8079 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
8080 Rewrite in terms of the above.
8081 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
8082 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
8083 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
8084 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
8086 2003-09-02 Paul Eggert <eggert@twinsun.com>
8088 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
8089 Document problems with timestamp resolution that 'make', 'cp -p', and
8090 'touch -r' have.
8092 2003-08-27 Akim Demaille <akim@epita.fr>
8094 * tests/m4sugar.at (cross_warning): Make sure to enable the
8095 output, so that we can track spurious m4sugar output.
8096 * tests/local.at: Require 2.57.
8097 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
8098 are defaulted by AT_CHECK anyway.
8099 Use AT_CHECK_AUTOM4TE.
8100 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
8101 missing dnl.
8103 2003-08-27 Akim Demaille <akim@epita.fr>
8105 * bin/autoheader.in: Issue the "Using auxiliary..." message only
8106 when -Wobsolete is set.
8107 Set it on by default.
8108 Suggested by Klee Dienes.
8110 2003-08-27 Akim Demaille <akim@epita.fr>
8112 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
8113 documentation.
8114 From Guido Draheim.
8116 2003-08-26 Akim Demaille <akim@epita.fr>
8118 * doc/autoconf.texi (Output): Make clear that one can run code
8119 after AC_OUTPUT.
8121 2003-08-25 Akim Demaille <akim@epita.fr>
8123 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
8124 CVS Bison.
8126 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
8128 * bin/autoreconf.in (parse_args): Do not pass --no-force to

8145 * Makefile.maint (local-check): Rename as...
8146 (local-checks-available): this.
8147 (local-check): New.
8149 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
8150 * configure.ac: Require Automake 1.7.6.
8152 2003-08-22 Akim Demaille <akim@epita.fr>
8154 Output stack traces in warnings.
8156 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
8157 Replace the former...
8158 (m4_warn): Pass the call stack to _m4_warn.
8159 * bin/autom4te.in: Adjust to output the call stack.
8160 * tests/m4sugar.at (m4@&t@_warn): Adjust.
8162 2003-08-22 Akim Demaille <akim@epita.fr>
8164 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
8165 * bin/autom4te.in: Adjust.
8167 2003-08-21 Akim Demaille <akim@epita.fr>
8169 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
8170 (&verbose): Remove.
8171 (&getopt): Adjust the note and verb channels, depending upon
8172 --verbose.
8173 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
8174 * bin/autoupdate.in: Adjust.
8175 Use &verb, not &verbose.
8177 2003-08-21 Akim Demaille <akim@epita.fr>
8179 * bin/autoheader.in (&parse_args): Use &parse_warnings and
8180 &parse_WARNINGS.
8181 ($help): Use Autom4te::ChannelDefs::usage.
8182 * bin/autoscan.in: Use Autom4te::ChannelDefs.
8183 * lib/Autom4te/General.pm: Don't export error: you don't own it.
8185 2003-08-21 Akim Demaille <akim@epita.fr>
8187 First stab at preserving warnings between calls to autom4te,
8188 including when the cache is used.
8190 There are still several issues: (i) there are too many runs of m4
8191 (one for include, one for warnings, and some more), (ii) warnings
8192 spreading on several lines are not handled gracefully, (iii) the
8193 code meant to have the call stack display for errors does not work
8194 (its handling should move from m4 to autom4te).
8196 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
8197 Use them.
8198 (@preselect): Add m4_warn.
8199 ($exit_status): Remove, use $exit_code.
8200 ($help): Use Autom4te::ChannelDefs::usage.
8201 (&handle_m4): No longer define the m4_warnings.
8202 At each run, extract and report the warnings.
8203 Always cache the result, including if the exit status is on
8204 failure, since if nothing changes, we should result in the same
8205 failure, hence we can use the cache.
8206 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
8207 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
8208 Remove.
8209 (m4_warn): Redefine as a do-nothing: it is its invocation that
8210 matters, as warnings are now reported via traces.
8211 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
8212 the contents of m4_warn: make it _call_ m4_warn, so that tracing
8213 the latter reveals calls to the former.
8215 Adjust the tests.

8254 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
8255 (&xsystem, &contents): Remove, since they are exported by...
8256 * lib/Autom4te/FileUtils.pm: this.
8257 More perldoc.
8258 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
8259 * lib/Autom4te/FileUtils.pm: here.
8261 2003-08-20 Akim Demaille <akim@epita.fr>
8263 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
8264 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

8317 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
8318 shorter column three. Add DESCRIPTION to log file content.
8320 2003-08-13 Derek Price <derek@ximbiot.com>
8322 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
8323 output.
8325 2003-08-12 Derek Price <derek@ximbiot.com>
8327 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
8328 (AT_CHECK_NOESCAPE): Move core functionality to...
8329 (_AT_CHECK): ...this new macro.
8331 2003-08-07 Derek Price <derek@ximbiot.com>
8333 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
8334 (AT_CHECK_NOESCAPE): ...to this new macro.
8336 2003-07-31 Paul Eggert <eggert@twinsun.com>
8338 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
8339 in Bash 2.01. Problem reported by Brian Gough in
8340 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
8342 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
8344 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
8345 -lcrt1.o, for OS X. (trivial change)
8347 2003-07-07 Paul Eggert <eggert@twinsun.com>
8349 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
8350 inside '#ifndef __cplusplus'. Problem reported by
8351 Bob Friesenhahn.
8353 2003-07-06 Bill Clarke <llib@computer.org>
8355 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
8356 'long', not 'int', for benefit of Sun's recent C++ compilers
8357 (trivial change). See:
8358 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
8359 (This really should be 'intptr_t', not 'long', but that would
8360 take more work.)
8362 2003-06-25 Akim Demaille <akim@epita.fr>
8364 * lib/Makefile.am (autom4te.cfg): Make it read only.
8365 Depend on Makefile since it contains substitutions.
8366 From Paolo Bonzini.

8368 This change was made on autom4te.cfg which is generated.
8369 Reported by Raja R. Harinath.
8371 2003-06-25 Akim Demaille <akim@epita.fr>

8374 From Gareth McCaughan.
8376 2003-06-23 Akim Demaille <akim@epita.fr>
8378 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
8379 not all of them. This fixes 1. the fact that when testing
8380 Autoconf there are many many config.log, 2. the incorrect use of
8381 top_srcdir to find config.log.
8382 Don't mix the detailed output of failed test with the summary of
8383 failures. Rather, append detailed log afterwards.
8385 2003-06-23 Akim Demaille <akim@epita.fr>
8387 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
8388 always run: output config.log on $at_group_log.
8390 2003-06-23 Akim Demaille <akim@epita.fr>
8392 * tests/torture.at (#define header templates): Don't use quotes in

8395 2003-06-23 Akim Demaille <akim@epita.fr>
8397 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
8398 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
8399 * tests/atspecific.m4: Rename as...

8402 * tests/local.at: here.
8403 * tests/Makefile.am: Adjust.
8404 * doc/autoconf.texi (testsuite Scripts): Adjust.
8406 2003-06-21 Kevin Ryde <user42@zip.com.au>
8408 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
8409 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
8410 ensuring we add -std1 for full-ANSI.
8412 * doc/autoconf.texi (hdrindex): New macro.
8413 Add index entries for portability of various standard header files.
8415 2003-06-20 Akim Demaille <akim@epita.fr>
8417 * configure.ac: Bump to 2.57b.
8419 2003-06-20 Akim Demaille <akim@epita.fr>
8421 Version 2.57a.
8423 2003-06-20 Akim Demaille <akim@epita.fr>
8425 * bin/autom4te.in: Don't rely on $HOME being defined.
8426 Reported by Marc Espie as PR/233.
8428 2003-06-20 Akim Demaille <akim@epita.fr>
8430 * lib/autotest/general.m4: Use at_times_file only if used.
8431 From Nicolas Joly.
8433 2003-06-20 Akim Demaille <akim@epita.fr>
8435 * config/config.guess, config/config.sub, config/elisp-comp,
8436 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
8437 Update from masters.
8439 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
8441 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
8442 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
8443 (TEST_SCRIPT): New diversion.
8444 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
8445 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
8446 (AT_INIT): Support for expected failures.
8448 2003-06-02 Akim Demaille <akim@epita.fr>
8450 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
8451 changes.
8452 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
8453 Autoconf nor Automake.
8454 (&contents): New, from Automake.
8455 PODify.
8457 2003-05-28 Paul Eggert <eggert@twinsun.com>
8459 * NEWS, doc/autoconf.texi (Particular Functions),
8460 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
8461 is the inverse of localtime.
8463 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
8465 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
8466 (handle_exec_errors): New function. Work around $! being
8467 altered by WEXITSTATUS.
8468 (xqx, xsystem): Use handle_exec_errors.
8470 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
8472 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
8473 Do not call `_exit()', simply modify `$?'.
8474 (xsystem): Reset $! before running system, and check it afterward.
8475 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
8476 63 for version mismatches.
8478 2003-05-23 Akim Demaille <akim@epita.fr>
8480 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
8481 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
8482 the middle of a line).
8483 * lib/m4sugar/m4sugar.m4: Likewise.
8484 Remove useless spaces in comments.
8486 2003-05-23 Akim Demaille <akim@epita.fr>
8488 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
8489 exit 63, so that we (or Automake's "missing") can tell the
8490 difference with a plain failure.
8491 * doc/autoconf.texi (Notices): Adjust.
8493 2003-05-23 Akim Demaille <akim@epita.fr>
8495 * Makefile.am, bin/Makefile.am, config/Makefile.am,
8496 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
8497 White spaces cleanup.
8499 2003-05-22 Jim Meyering <jim@meyering.net>
8500 Paul Eggert <eggert@twinsun.com>
8502 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
8503 Remove `#include <stdlib.h>' from the list; we should never
8504 make confdefs.h include <stdlib.h> or <cstdlib>, because the
8505 resulting namespace pollution would cause other tests to fail.
8506 Configure scripts run with some older versions of g++ and HP's
8507 aCC would fail due to such an #include. Problems reported by
8508 Matthew Mueller in <http://bugs.debian.org/120704> and by
8509 Keith Bostic in
8510 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
8511 In the test, use the test declaration before including <stdlib.h>,
8512 as that's closer to how it'll be used.
8514 2003-05-23 Akim Demaille <akim@epita.fr>
8516 * doc/autoconf.texi (Header Portability): ucred.h.
8517 From Ian Redfern.
8519 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8521 Overhaul Autotest's logging: generate separate log files
8522 in testsuite.dir/NNN/testsuite.log, and append them to
8523 testsuite.log instead of re-running the test verbosely.
8525 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
8526 file descriptor, write 0 to at_status_file instead of setting
8527 at_status=0, initialize some new variables (at_status_file,
8528 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
8529 to rerun the tests, instead append the at_group_log to the
8530 at_suite_log when a test fails.
8531 (AT_SETUP): pipe the test case's output into at_tee_pipe,
8532 with the AS_MESSAGE_LOG_FD redirected to stdout.
8533 (AT_CLEANUP): save the output status in $at_status_file
8534 and restore it, redirect the AS_MESSAGE_LOG_FD back to
8535 its original place.
8536 (AT_CHECK): since tests are run with a redirected stdout,
8537 and used to be re-run in verbose mode, turn some $at_verbose
8538 into echo, and don't redirect the output of testing stdout
8539 and stderr.
8541 * lib/autotest/autoconf.texi (testsuite Scripts): Update
8542 the name of the debugging directory and information about
8543 its contents.
8545 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8547 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
8548 parameter.
8550 2003-05-22 Akim Demaille <akim@epita.fr>
8552 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4
8553 * lib/autoconf/fortran.m4 lib/autoconf/general.m4
8554 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4

8571 Suggested by Jim Meyering.
8573 2003-05-22 Akim Demaille <akim@epita.fr>
8575 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
8576 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
8577 Reported by Jim Meyering.
8579 2003-05-22 Akim Demaille <akim@epita.fr>
8581 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

8600 * bin/autoupdate.in ($m4): Fix quotation.

8603 2003-05-19 Paul Eggert <eggert@twinsun.com>
8605 * ChangeLog, ChangeLog.2, THANKS, lib/m4sugar/m4sugar.m4:

8612 AC_CHECK_HEADERS_NEW): New tests.
8614 2003-05-17 Akim Demaille <akim@epita.fr>
8616 * lib/autoconf/functions.m4: Use the default includes so that
8617 memcmp be declared before being tested.
8618 Reported by Sander Niemeijer.
8619 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
8620 * doc/autoconf.texi (Default Includes): Document
8621 AC_INCLUDES_DEFAULT.
8623 2003-05-17 Akim Demaille <akim@epita.fr>
8625 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
8626 * doc/autoconf.texi (Obsolete Macros): Adjust.
8627 Reported by Werner LEMBERG and Debian Bug 190886.
8629 2003-05-16 Akim Demaille <akim@epita.fr>
8631 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
8632 user name space clashes.
8633 Reported by Bruno Haible.
8635 2003-05-16 Akim Demaille <akim@epita.fr>
8637 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
8638 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
8639 them uniform, and more robust to Perl special characters.
8640 Reported by Martin Mokrejs.
8642 2003-05-14 Akim Demaille <akim@epita.fr>
8644 * tests/foreign.at (Libtool): Skip all Libtools pre 1.4.
8646 2003-05-14 Akim Demaille <akim@epita.fr>
8648 * doc/autoconf.texi (Header Portability): X11/extensions/scrnsaver.h,

8653 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Improve the
8654 message.
8655 From Matthias Andree.
8657 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
8659 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
8660 and truncate.
8662 2003-05-06 Akim Demaille <akim@epita.fr>
8664 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
8665 longer updates aclocal.m4 if useless, (ii) if a file m4_included
8666 by aclocal.m4 is changed it might require the importing of another
8667 m4 extension file, i.e., aclocal must be run.
8669 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
8670 (&parse_args): Use --force with aclocal if required and supported.
8671 (&autoreconf_current_directory): Use &run_aclocal.
8673 2003-05-06 Akim Demaille <akim@epita.fr>
8675 Lock autom4te's cache.
8677 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
8678 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
8679 argument instead of a file name, so that the request file remains
8680 open during the whole autom4te run.
8681 ($icache_file): New.
8682 (&freeze): Lock the $icache_file.
8684 2003-04-29 Derek Price <derek@ximbiot.com>
8686 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
8687 seperator with m4_append_uniq(). It doesn't work.
8688 (AT_CLEANUP): Add `;' to end of at_help_all.
8689 (AT_INIT): Allow --keywords to be specified more than once. When
8690 grepping $at_help_all for keywords, use the field and keyword
8691 seperators to ensure a complete keyword match. Alter at_prev handling
8692 to support the new --keywords behavior.
8694 2003-04-27 Karl Berry <karl@freefriends.org>
8696 * doc/autoconf.texi: Make the dir entries in the autoconf manual
8697 align better with others. I also made some of the individual
8698 entries on one line, for brevity and to make it easier for me to
8699 sort my dir-example file in the Texinfo distribution :).
8701 2003-04-12 Jim Meyering <jim@meyering.net>

8862 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
8863 to cope with DOS-style absolute paths, when constructing
8864 ${ac_make}.
8866 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
8867 When constructing paths with IFS=:, quote the path. If we're
8868 constructing a DOS-style absolute path, we don't want to split it
8869 on the colon.
8871 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
8872 in description.
8874 2003-02-25 Pavel Roskin <proski@gnu.org>

8886 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
8887 to fix a mismatch between example and discussion.

8891 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
8892 format starting with "-".
8894 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
8896 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
8897 is not portable inside Makefile.
8899 2003-02-20 Akim Demaille <akim@epita.fr>
8901 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
8902 compiler says yeah, but preproc says nope, compiler is right.
8903 Conversely, prompt the reader to send a bug report to the
8904 maintainers of the package, not of Autoconf.
8906 2003-02-20 Klee Dienes <kdienes@apple.com>
8908 * bin/autoreconf.in (autoreconf_current_directory): Properly

8914 $ac_prefix_program.
8915 From Larry Jones.
8917 2002-12-23 Paul Eggert <eggert@twinsun.com>
8919 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
8920 innocuous variant befor including <limits.h> or <assert.h>. This
8921 works around a bug reported by Albert Chin: HP-UX 11i
8922 (and earlier versions) have a <limits.h> that declares
8923 gettimeofday and many other functions.
8925 2002-12-03 Paul Eggert <eggert@twinsun.com>
8927 Version 2.57.
8929 * NEWS, configure.ac: Update version.
8931 * doc/fdl.texi: Upgrade to FDL version 1.2.
8933 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
8934 nontrivially in main's body, so that f's external declaration is
8935 not optimized away in AIX. This should fix the bug reported by
8936 Martin Frydl in
8937 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
8939 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
8940 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
8941 defined, to support freestanding compilers. This should fix the
8942 bug reported by Momchil Velkov in
8943 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
8945 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
8946 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

8957 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
8958 \(.*\) match is too long and there is something more to be checked.
8959 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
8961 2002-11-15 Akim Demaille <akim@epita.fr>

8968 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
8969 * configure.ac (AM_INIT_AUTOMAKE): here.
8970 Require 1.7.1.
8972 2002-11-14 Akim Demaille <akim@epita.fr>
8974 Version 2.55.
8976 * config/config.guess, config/config.sub, config/install-sh:
8977 Update from masters.
8979 2002-11-14 Akim Demaille <akim@epita.fr>
8981 * Makefile.maint: Sync with Bison, i.e.:
8982 (po-check): Scan .l and .y files instead of the
8983 .c and the .h files that they generate. This fixes the bug
8984 reported by Tim Van Holder in:
8985 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
8986 Look for N_ as well as for _. Try to avoid matching #define for
8987 N_ and _.
8988 From Paul Eggert.
8990 2002-11-14 Akim Demaille <akim@epita.fr>
8992 * doc/autoconf.texi (C Compiler): Compiling several files at once.
8993 From Paul Eggert and Albert Chin-A-Young.
8995 2002-11-14 Akim Demaille <akim@epita.fr>

8998 From Paul Eggert and Albert Chin-A-Young.
9000 2002-11-14 Kevin Ryde <user42@zip.com.au>
9002 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
9003 than assigning in main, to avoid HP cc +O3 optimizing it away.
9005 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
9007 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
9008 option. Process --recheck after parsing all options. Pass -q
9009 option to configure on --recheck.
9010 (AC_OUTPUT): Pass -q from configure to config.status.
9011 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
9012 arguments to record.
9013 * doc/autoconf.texi (config.status Invocation): Document
9014 config.status -q option.
9016 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

9019 Makefile.in if Makefile.am exists.
9020 (output): Strip `.am' from Makefiles. Don't
9021 output AC_CONFIG_FILES if no Makefiles were found.
9023 2002-11-07 Akim Demaille <akim@epita.fr>

9030 2002-11-06 Akim Demaille <akim@epita.fr>
9032 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
9033 declaration in extern "C" too.

9038 * tests/torture.at (Configuring subdirectories): Don't use grep
9039 -w.
9040 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
9041 Reported by Ezra Peisach.
9043 2002-11-05 Akim Demaille <akim@epita.fr>
9045 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
9046 Remove.
9047 We _have_ to stop using the old compatibility scheme that tried to
9048 avoid useless backslashes because Libtool 1.4.3 contains a
9049 AC_DEFINE([error_t], [int],
9050 [Define to a type to use for \`error_t' if it is not
9051 otherwise available.])
9052 We _have_ to quote the single quote and backslashes with \. The
9053 old compatibility scheme saw that ` was backslashed, and therefore
9054 did not quote the single quote. Hence before this patch, Autoconf
9055 was not compatible with Libtool.
9057 2002-11-04 Paul Eggert <eggert@twinsun.com>
9059 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

9064 2002-11-04 Akim Demaille <akim@epita.fr>
9066 Version 2.54c.
9068 * Makefile.maint (update, cvs-update, po-update, do-po-update):
9069 New.
9070 * config/texinfo.tex: Update.
9072 2002-11-03 Akim Demaille <akim@epita.fr>
9074 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
9075 from...
9076 (&autoreconf): here.
9077 ($help, $make, &parse_args, &autoreconf_current_directory):
9078 Support -m/--make.
9079 * doc/autoconf.texi (autoreconf Invocation): Adjust.

9094 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
9095 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
9097 2002-10-31 Akim Demaille <akim@epita.fr>
9099 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
9100 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
9101 Make variable, not a shell variable.
9102 Suggested by Bruno Haible.
9104 2002-10-31 Akim Demaille <akim@epita.fr>
9106 * bin/autom4te.in (load_configuration): Reject #args out of any
9107 language.
9109 2002-10-31 Akim Demaille <akim@epita.fr>
9111 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
9112 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
9113 (_AC_RUN_IFELSE): Use it.
9114 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
9115 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
9116 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
9117 inline it.

9123 Suggested by Tim van Holder.
9125 2002-10-29 Paul Eggert <eggert@twinsun.com>
9127 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
9128 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
9129 Problem reported by Bruno Haible.
9131 2002-10-29 Akim Demaille <akim@epita.fr>
9133 * doc/autoconf.texi (Header Templates): Put also in words what the
9134 pictures says to assist free style readers.
9135 (Customizing autom4te): s/--cache=/--cache /.
9137 2002-10-29 Akim Demaille <akim@epita.fr>
9139 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
9140 sys/wait.h.
9141 sparc_address_test returns void.
9142 Use it with an argument, as prototyped.
9143 From Bruno Haible.
9145 2002-10-29 Akim Demaille <akim@epita.fr>
9147 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

9153 * tests/torture.at (Deep Package): New test.

9159 * bin/autoreconf.in (&parse_args, $help): Support --warnings.
9160 * doc/autoconf.texi (Invoking autom4te): Rename as...
9161 (autom4te Invocation): this, for consistency with the other nodes.
9163 2002-10-29 Akim Demaille <akim@epita.fr>
9165 * lib/autom4te.in (Autoconf): s/automate/autom4te/.
9166 Reported by Ralf Corsepius.

9176 * configure.ac: Bump to 2.54c.

9387 2002-10-22 Akim Demaille <akim@epita.fr>
9389 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

9393 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
9394 strings.
9396 2002-10-22 Akim Demaille <akim@epita.fr>
9398 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

9445 longer required can still cause errors.
9446 Reported by Alexandre Duret-Lutz.
9448 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
9449 to frozen files in @ARGV, as @ARGV must remain being a list of

9451 (&files_to_options): New function.
9452 (&freeze): Use &error.
9453 (&up_to_date): If a file that was included according to the cache
9454 is no longer there, then the output is out dated.
9455 (&main): Don't even check whether a file is up to date is anyway
9456 --force is given.
9457 * tests/tools.at (autom4te cache): New.

9464 Factor some code.
9465 (&autoreconf): Report the directories we enter *and leave*, so
9466 that error messages can be easily located, and use GNU Make
9467 format, so that Emacs' compile mode understands us.
9468 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
9469 if some file was changed instead of `print'.
9470 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

9504 file name to enable parallel executions.
9505 From Sam Varshavchik.
9507 2002-10-08 Akim Demaille <akim@epita.fr>
9509 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
9510 aclocal invocation, as Gettext macros might not be visible to
9511 aclocal.
9512 Instead of blindly running autopoint, scan configure.ac (not the
9513 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
9514 Reported by Paul D. Smith.
9516 2002-10-08 Paul Eggert <eggert@twinsun.com>
9518 Work around problems found when POSIXLY_CORRECT=1 is set.
9519 None of this seems to have anything to do with POSIX, really,
9520 but it's how Perl getopt works.
9521 * bin/autom4te.in (parse_args): Configure GetOpt with
9522 "permute", too.
9523 * doc/autoconf.texi (Invoking autom4te):

9546 * tests/torture.at (Configuring subdirectories): Be robust to
9547 users who use config.site to require for a cache: in this case,
9548 the two last configure runs, using two different sets of
9549 arguments, trigger a legitimate error.
9551 2002-09-28 Akim Demaille <akim@epita.fr>

9570 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
9571 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

9586 tests/autom4te itself.
9587 * lib/autoscan/Makefile.am: Include freeze.mk.
9588 (autoscan.list): New target --this file is no longer a source.
9589 (autoscan.pre): New file.

9596 tracking changes in autoscan.list.
9597 * lib/autoscan/autoscan.list (function): Strip comments, sort.
9599 2002-09-28 Akim Demaille <akim@epita.fr>

9613 * bin/autoscan.in (&init_tables): Adjust.
9615 2002-09-28 Akim Demaille <akim@epita.fr>
9617 From now on, autoscan files must always map a macro name to a
9618 word: there is no `default' macro for autoscan.
9620 * bin/autoscan.in (&init_tables): Reject entries with no macro at
9621 all.
9622 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
9623 explicit.
9625 2002-09-28 Akim Demaille <akim@epita.fr>
9627 * bin/autoscan.in (%c_keywords): Remove.

9693 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
9695 2002-09-13 Paul Eggert <eggert@twinsun.com>
9697 * doc/autoconf.texi (Particular Headers): Remove obsolete
9698 reference to `struct timezone' in the description of
9699 AC_HEADER_TIME.
9701 2002-09-13 Akim Demaille <akim@epita.fr>
9703 Version 2.54.
9705 * config/config.sub, config/config.guess: Update.
9706 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
9707 * Makefile.am: Adjust.
9709 2002-09-13 Akim Demaille <akim@epita.fr>
9711 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
9712 reading config.log when the compiler is rejected.
9713 Suggested by Guido Draheim.
9715 2002-09-13 Akim Demaille <akim@epita.fr>
9717 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
9718 (chdir_init) might hang when stat'ing mounted directories.
9719 Reported by Vance Shipley.
9721 2002-09-12 Akim Demaille <akim@epita.fr>
9723 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
9724 the lists.
9726 2002-09-12 Akim Demaille <akim@epita.fr>
9728 * doc/autoconf.texi (Defining Symbols): Present two different
9729 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
9730 difference between 1 argument calls, and 2-3 argument calls.
9732 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
9734 * doc/autoconf.texi: Review grammar and punctuation.
9736 2002-09-11 Paul Eggert <eggert@twinsun.com>
9738 * doc/autoconf.texi: Fix minor formatting, spelling, and
9739 grammatical typos.
9740 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
9741 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
9742 is obsolescent.
9744 2002-09-11 Akim Demaille <akim@epita.fr>
9746 * doc/autoconf.texi (Questions): Rename as...
9747 (FAQ): this.
9748 (Defining Directories): New.
9750 2002-09-09 Akim Demaille <akim@epita.fr>
9752 * doc/autoconf.texi (Making testsuite Scripts): Update.
9753 Suggested by Nishio Futoshi.
9755 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
9757 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
9758 plain `@' is wanted.
9760 2002-09-09 Akim Demaille <akim@epita.fr>
9762 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
9763 `duplicates', since the algorithm was too naive and could keep
9764 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
9765 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
9766 Reported by Ralf Corsepius.
9767 * tests/torture.at (Configuring subdirectories): Exercise these
9768 cases.
9770 2002-09-09 Akim Demaille <akim@epita.fr>
9772 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
9773 looking for a replacement file.
9774 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
9775 directory is relative.
9776 * doc/autoconf.texi (Generic Functions): Clarify the replacement
9777 directory definition.
9778 Reported by Andreas Schwab and Jim Meyering.
9780 2002-09-06 Akim Demaille <akim@epita.fr>
9782 * doc/autoconf.texi (Setting Output Variables): Clarify what
9783 precious variables are.
9784 Suggested by Pontus Skoeld.
9786 2002-09-05 Akim Demaille <akim@epita.fr>
9788 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9789 (ifnames, autoscan, autom4te): Since we don't only depend on
9790 configure.ac variables (such as VERSION etc.), but also on prefix
9791 and so forth, depend on Makefile, not configure.ac.
9792 Reported by Alexandre Duret-Lutz.
9793 * doc/autoconf.texi (Installation Directory Variables): Adjust.
9795 2002-09-05 Kevin Ryde <user42@zip.com.au>
9797 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
9798 doesn't seem to be confined to ia64, just say "some versions".
9800 2002-09-04 Akim Demaille <akim@epita.fr>
9802 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
9803 Automake 1.6c.
9804 * Makefile.am (maintainer-clean-local): Remove.
9805 (MAINTAINERCLEANFILES): Remove COPYING.
9807 2002-09-03 Paul Eggert <eggert@twinsun.com>
9809 * doc/autoconf.texi (Configuration Commands): Remove obsolete
9810 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
9811 Brinkmann.
9813 2002-09-03 Akim Demaille <akim@epita.fr>
9815 * configure.ac: Bump to 2.53d.
9816 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
9817 as of today, on Automake's team suggestion.
9819 2002-09-03 Akim Demaille <akim@epita.fr>
9821 Version 2.53c.
9823 2002-09-02 Akim Demaille <akim@epita.fr>
9825 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
9826 SITE_MACRO_DIR.
9827 * configure.ac: Disable SITE_MACRO_DIR.
9829 2002-09-02 Jim Meyering <meyering@lucent.com>
9831 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
9832 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
9833 Also, tweak grammar: s/make sure to/be sure to/.
9835 2002-09-02 Paul Eggert <eggert@twinsun.com>
9837 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
9838 directory names are generally preferable to physical names.
9840 2002-09-02 Akim Demaille <akim@epita.fr>
9842 * lib/Autom4te/General.pm (&update_file): s/die/error/.
9843 Reported by Raja R. Harinath.
9844 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
9845 * bin/autoupdate.in: Use error instead of die.
9847 2002-09-01 Paul Eggert <eggert@twinsun.com>
9849 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
9850 ordinary shell concatenation rather than echo+tr+sed command that
9851 runs afoul of a long-line-related sed bug in Solaris 8.
9853 * bin/autoheader.in (parse_args): --warning -> --warnings.
9855 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
9856 stdout, as traditional "ls" does.
9857 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
9858 _AC_COMPILER_EXEEXT_O): Likewise.
9859 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
9861 * bin/autoconf.as: Add --prepend-include option. This patch was
9862 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
9863 but bin/autoconf.in is generated automatically from bin/autoconf.as.
9865 * bin/autoconf.in, configure: Regenerate.
9867 * doc/autoconf.texi (Special Shell Variables): Mention
9868 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
9870 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
9871 MAILPATH and set PS1, PS2, PS4 to default values, to work
9872 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
9873 For LC_ALL etc, first try to set to "C" as POSIX requires and as
9874 the Autoconf documentation specifies; fall back to "unset" only if
9875 this fails. Use a shell for-loop for this rather than an m4 loop,
9876 to shorten the output script.
9878 2002-08-30 Paul Eggert <eggert@twinsun.com>
9880 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
9881 1003.1-2001's requirements for CDPATH. Give a simpler workaround
9882 for the CDPATH problem. Document PWD.
9883 (Limitations of Builtins): Document the problem that "cd $foo" and
9884 "ls $foo" may refer to different directories in shells conforming
9885 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
9886 example, since the old example is now out of date.
9888 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
9889 FOO" and "ls FOO" talk about different directories; this catches
9890 problems when POSIX 1003.1-2001 "cd" fails due to symlink
9891 spaghetti.
9893 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
9894 of rolling our own unset.
9895 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
9896 in practice we needn't worry about CDPATH if unset doesn't work.
9898 * Makefile.in, aclocal.m4, bin/Makefile.in,
9899 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
9900 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
9901 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
9902 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
9903 tests/Makefile.in: Regenerate with Automake 1.6.3.
9905 * config/config.guess, config/config.sub, config/mkinstalldirs:
9906 Update.
9908 * configure: Regenerate with self.
9910 2002-08-30 Kevin Ryde <user42@zip.com.au>
9912 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
9913 default output.
9915 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
9917 * bin/autom4te.in (Request::load): Correctly test for "do" read
9918 failure.
9920 2002-08-29 Akim Demaille <akim@epita.fr>
9922 * lib/Autom4te/General.pm (&xqx): New.
9923 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
9924 hand, which is not portable.
9925 (&error): New.
9926 * bin/autom4te.in: Use them.
9927 Use &error instead of die.
9928 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
9929 Adjust.
9931 2002-08-17 Paul Eggert <eggert@twinsun.com>
9933 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
9934 default list of compilers to try, since it was long ago superseded
9935 by the ksh fc builtin. Suggested by Steven G. Johnson.
9937 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
9939 * doc/autoconf.texi (Invoking autom4te): End the option table,
9940 fixing a bug introduced by the previous patch.
9941 (Limitations of Make): Add a 'target lookup' subentry in the
9942 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
9944 2002-07-29 Mark D. Roth <roth@feep.net>
9946 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
9947 options and use $AUTOM4TE_PATH.
9948 * doc/autoconf.texi: Remove documentation of autom4te
9949 --include-envvar and --site-macro-subdir options and document
9950 use of $AUTOM4TE_PATH.
9951 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
9952 arguments from each language section.
9954 2002-07-29 Paul Eggert <eggert@twinsun.com>
9956 * doc/install.texi: Include copyright symbol in copyright notice.
9958 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
9959 Replace with:
9960 (AM_MAKEINFOFLAGS): New macro.
9961 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
9962 * Makefile.am (INSTALL): Use the new macros.
9963 Use -o rather than --output, since "missing" does not grok --output.
9965 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9967 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
9968 comments do not always work. Never trust the exit status of
9969 `make -k'.
9971 2002-07-24 Kevin Ryde <user42@zip.com.au>
9973 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
9974 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
9976 2002-07-23 Paul Eggert <eggert@twinsun.com>
9978 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
9979 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
9980 apparently treats PATH="nonexistent" as if it contained ".".
9981 Bug reported by Stefan `Sec' Zehl.
9983 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9985 * doc/autoconf.texi (Limitations of Make): Mention the special
9986 handling of the obj/ directory by BSD make.

10002 2002-07-18 Akim Demaille <akim@epita.fr>
10004 Version 2.53b.
10006 2002-07-18 Akim Demaille <akim@epita.fr>
10008 * config/config.guess, config/config.sub: Update.
10010 2002-07-18 Akim Demaille <akim@epita.fr>
10012 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and

10016 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
10017 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
10019 2002-07-18 Akim Demaille <akim@epita.fr>,
10020 Alexandre Duret-Lutz <duret_g@epita.fr>
10022 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install

10032 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
10033 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
10034 latter was not run.

10038 * lib/Autom4te/General.pm (find_file): Browse the directories in
10039 the order they are given.

10062 * tests/wrapsh.in: Use --prepend-include instead of --include.
10064 2002-07-17 Akim Demaille <akim@epita.fr>

10107 2002-06-27 Paul Eggert <eggert@twinsun.com>
10109 * config/install-sh: Quote $src. Prefer || to test's -o option,
10110 as per "Limitations of Builtins".
10111 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
10112 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
10114 * tests/mktests.sh: Use grep instead of fgrep, as per
10115 "Limitations of Builtins".
10117 2002-06-15 Paul Eggert <eggert@twinsun.com>
10119 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
10120 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
10121 so that we consistently test the just-built programs.
10122 * tests/wrappl.as: Likewise.
10124 2002-06-12 Paul Eggert <eggert@twinsun.com>
10126 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
10127 name, so that symlinks to 'autoconf' work properly. Bug reported
10128 by Bruno Haible.
10129 * bin/autoheader.in (AUTOM4TE): Likewise.
10130 * bin/autoreconf.in (autoconf, autoheader): Likewise.
10131 * bin/autoscan.in (autom4te): Likewise.
10132 * bin/autoupdate.in (autom4te): Likewise.
10134 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
10135 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
10136 on Solaris 2.5.1.
10138 2002-06-11 Andreas Schwab <schwab@suse.de>
10140 * doc/autoconf.texi: Add more dir entries.
10142 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
10144 * bin/autom4te.in ($cache): Don't define using `$me', the name
10145 of the cache should not depend on the name under which autom4te
10146 was installed.
10148 2002-06-07 Akim Demaille <akim@epita.fr>
10150 * tests/tools.at (autoconf: forbidden tokens, basic)
10151 (autoconf: forbidden tokens, exceptions): Adjust to the change of
10152 words in autom4te.in.

10182 (AC_CONFIG_LIBOBJ_DIR): New.
10183 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
10184 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
10185 Use ac_config_libobj_dir to find the replacement files.
10186 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
10187 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
10188 (AC_REPLACE_FNMATCH_GNU): these.
10189 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
10190 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
10191 * tests/mktests.sh (ac_exclude_list): Don't check
10192 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
10194 2002-06-06 Paul Eggert <eggert@twinsun.com>
10196 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
10197 if ln doesn't work.
10198 * NEWS: Likewise.
10199 * doc/autoconf.texi (Configuration Links): Likewise.
10200 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
10202 2002-06-05 Paul Eggert <eggert@twinsun.com>
10204 * config/config.guess, config/config.sub, config/texinfo.tex:
10205 Update from masters.
10207 2002-05-29 Paul Eggert <eggert@twinsun.com>

10230 * NEWS, doc/autoconf.texi (Particular Types): Document it.
10231 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it

10234 2002-05-23 Akim Demaille <akim@epita.fr>

10237 version of Autoconf that is discussed.
10239 2002-05-22 Paul Eggert <eggert@twinsun.com>
10241 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
10242 from the default list of compilers to try. Suggested by
10243 Kate Hedstrom.
10244 * NEWS: Document the above.
10245 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
10247 2002-05-17 Paul Eggert <eggert@twinsun.com>
10249 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
10250 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
10251 This improves on an earlier suggestion by H. Peter Anvin.
10253 2002-05-16 Paul Eggert <eggert@twinsun.com>
10255 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
10256 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
10257 Both macros now accept an optional source-dir arg.
10258 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
10260 * NEWS: Document this.
10261 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
10263 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
10264 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
10265 not for GNU extensions; this undoes part of the 2000-11-03 change,
10266 reverting to 2.13-compatible behavior.
10267 Add new optional argument DIR.
10268 (AC_FUNC_FNMATCH_GNU): New macro.
10270 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
10272 2002-05-08 Paul Eggert <eggert@twinsun.com>
10274 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
10275 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
10276 and it causes a 'test' syntax error if it fails.
10277 Bug reported by Stephen Gildea.
10279 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
10280 If prototypes are supported, use them to check this at compile-time,
10281 instead of trying to check it at run-time. If we must do a run-time
10282 check, assume that setvbuf is standard when cross-compiling, as
10283 nonstandard setvbuf occurs only on ancient and unlikely hosts.
10284 Bug reported by Paul D. Smith.
10286 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
10287 argument specifying location of getloadavg.c. This removes a
10288 FIXME. This idea was taken from Jim Meyering's implementation in
10289 textutils.
10290 * doc/autoconf.texi (Particular Functions): Document this.
10291 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
10292 that's what the code does; this fixes a bug reported by
10293 Paul D. Smith.
10295 2002-05-03 Akim Demaille <akim@epita.fr>
10297 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
10298 autopoint instead of gettextize.
10299 ($uses_alocal): Rename as...
10300 ($uses_aclocal): this.
10301 * doc/autoconf.texi (autoreconf Invocation): Adjust.
10302 Suggested by Bruno Haible.
10304 2002-05-03 Akim Demaille <akim@epita.fr>
10306 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
10308 2002-04-29 Paul Eggert <eggert@twinsun.com>
10310 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
10311 files to be 1 second older; just set them to be the same time.
10312 Also, sleep 1 second after the first aclocal, to work around
10313 problems with sub-second time stamps on the input files.
10315 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
10317 * doc/autoconf.texi: Mention "set -e -x" lossage
10318 under node "Limitations of Builtins".
10320 2002-04-29 Akim Demaille <akim@epita.fr>
10322 * doc/install.texi: Better wording for setting variables when
10323 running configure.
10324 From Christian Cornelssen.
10326 2002-04-29 Akim Demaille <akim@epita.fr>
10328 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
10329 of lack of $LINENO support, then the test will compare the $LINENO
10330 in testsuite vs. the lineno in the test file. This is wrong, of
10331 course.
10332 Be sure to protect it.
10333 Reported by Patrick Welche.
10335 2002-04-25 Akim Demaille <akim@epita.fr>
10337 * doc/autoconf.texi (Obsolete Macros): Typo.
10338 Reported by Vladimir Volovich.
10340 2002-04-25 Akim Demaille <akim@epita.fr>
10342 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
10343 than some of the input files, hence, on the second run of aclocal,
10344 if some of its input are younger, make them older.
10345 Suggested by Paul Eggert.
10347 2002-04-25 Akim Demaille <akim@epita.fr>
10349 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
10350 Thanks to Paul Eggert.
10352 2002-04-25 Akim Demaille <akim@epita.fr>
10354 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
10355 and ac_subst_vars be sh variables containing the list of
10356 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
10357 DEFAULT diversion.
10358 (_AC_INIT_PREPARE): Use them to log them.
10359 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
10360 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
10361 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
10362 _AC_SUBST_FILES and _AC_SUBST_VARS.
10363 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
10365 2002-04-24 Akim Demaille <akim@epita.fr>
10367 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
10368 autoheader, so that automake does not complain about a missing
10369 config.h.in that was to be created.
10371 2002-04-23 Akim Demaille <akim@epita.fr>
10373 * bin/autoheader.in (parse_args): --warning takes an argument.
10374 Fixes PR/220.

10393 Reported by Gregory Giannoni.
10395 2002-04-22 Akim Demaille <akim@epita.fr>
10397 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
10398 Fixes false failures on Darwin.

10423 Minor spelling and grammar fixes.
10425 * doc/autoconf.texi: Follow the outline suggested in the GNU
10426 Sample Texts sections of the Texinfo 4.2 manual. Most
10427 importantly, this makes sure that the copyright notices appear in
10428 all output formats. You probably need Texinfo 4.2 to generate
10429 the manual now.
10431 Fix some bugs when using "$@" when there might be zero positional
10432 arguments in cases where this matters.

10457 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

10478 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
10480 Adjust Autoconf and Autotest.
10482 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
10483 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
10484 * lib/autotest/general.m4 (AT_INIT): Likewise.
10485 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

10532 (AC_CONFIG_LINKS): here.
10533 Adjust.
10534 Don't use the KILL diversion, as it kills spurious output, which
10535 results in failures being hidden.
10536 Use m4_defn where appropriate.
10537 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
10538 after the second argument.
10539 Use m4_defn.
10540 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning

10646 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
10647 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
10648 back on AS_DIRNAME to compute prefixes otherwise; this is
10649 roughly what mkinstalldirs does. That way, we need not have
10650 our own filename disassembler. The old disassembler did not
10651 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
10653 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
10654 Create at_test_all by a series of assignments,
10655 not by a single assignment of a long string. The latter causes ksh
10656 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
10657 presumably because of a buffer overrun.
10659 2002-03-14 Paul Eggert <eggert@twinsun.com>
10661 * lib/autotest/general.m4 (at_times_skip):
10662 Renamed from at_times. Now a boolean.
10663 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
10664 says 'times: not found'.
10666 2002-03-14 Akim Demaille <akim@epita.fr>
10668 * bin/autoreconf.in (&study_gettextize): New.
10669 (&autoreconf): Handle newest gettextize.
10670 Rerun aclocal if needed.
10671 Suggested by Andreas Schwab.
10673 2002-03-13 Akim Demaille <akim@epita.fr>

10677 2002-03-13 Akim Demaille <akim@epita.fr>
10679 * doc/autoconf.texi (Header Portability): New.

10684 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
10685 -p'.
10686 From Bob Proulx.
10688 2002-03-12 Akim Demaille <akim@epita.fr>
10690 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
10691 m4_require.
10693 2002-03-11 Andreas Schwab <schwab@suse.de>
10695 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
10696 does not do it if --with-lispdir is given.
10698 2002-03-08 Akim Demaille <akim@epita.fr>
10700 Version 2.53.
10702 2002-03-08 Akim Demaille <akim@epita.fr>
10704 * doc/autoconf.texi (Subdirectories): Clarify that the
10705 subdirectory should exist.
10707 2002-03-08 Akim Demaille <akim@epita.fr>
10709 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
10711 2002-03-08 Akim Demaille <akim@epita.fr>
10713 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
10714 aliases the actual variables, and modifications of the former
10715 affect the latter.
10717 2002-03-08 Akim Demaille <akim@epita.fr>
10719 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
10720 because of C-c: have m4 output in tmp files, then mv them.
10722 2002-03-08 Akim Demaille <akim@epita.fr>
10724 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
10725 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,

10732 2002-03-05 Akim Demaille <akim@epita.fr>
10734 * doc/autoconf.texi (Specifying Names): Clarification suggested by
10735 Kevin Ryde.
10737 2002-03-05 Akim Demaille <akim@epita.fr>
10739 Version 2.52i.
10741 2002-03-04 Akim Demaille <akim@epita.fr>
10743 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
10744 * lib/autoconf/general.m4 (AC_INIT): More informative error
10745 message for LIBOBJ.
10747 2002-03-04 Akim Demaille <akim@epita.fr>
10749 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
10750 parallel builds.
10752 2002-03-04 Akim Demaille <akim@epita.fr>
10754 * doc/autoconf.texi (Transforming Names): Equality between target
10755 and host is irrelevant.
10756 (Specifying Names, Canonicalizing): Remove all references to the
10757 backward compatibility hooks. Rather, collect them all into...
10758 (Hosts and Cross-Compilation): this new section.
10759 * doc/install.texi (System Type): Ditto.
10760 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
10761 that `--host' implies cross-compilation.
10763 2002-03-04 Akim Demaille <akim@epita.fr>
10765 * doc/autoconf.texi (Evaluation Macros): New.
10766 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
10767 useless.
10768 (_m4_foreach): Define the variant with immediate evaluation so
10769 that it contains exactly the items, not an expression which
10770 evaluation is the current item.
10771 (m4_re_string, m4_re_word): Don't over quote them.
10773 2002-03-04 Akim Demaille <akim@epita.fr>
10775 Instead of having stacking `shift's evaluated at the end, let
10776 `foreach' loops immediately evaluate them.
10778 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
10779 $*. This is the n-th time I change my mind, but hopefully this is
10780 the last...
10781 (m4_lquote): New.
10782 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
10783 efficient.
10784 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
10785 it was only a hack for m4_text_wrap.
10786 (m4_car2): Remove, replaced by...
10787 (m4_cdr): New.
10788 (_m4_foreach): Adjust.
10789 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
10790 m4_bpatsubst for clarification.
10792 2002-03-04 Akim Demaille <akim@epita.fr>
10794 * doc/autoconf.texi (Changequote is Evil): New.
10796 2002-03-03 Kevin Ryde <user42@zip.com.au>
10798 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
10799 on old systems like SunOS.
10801 2002-03-01 Peter Eisentraut <peter_e@gmx.net>

10821 From Akinori Musha.
10823 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
10825 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
10826 translate \r\n to \n.
10828 2002-02-07 Akim Demaille <akim@epita.fr>
10830 Version 2.52h.
10832 2002-02-07 Akim Demaille <akim@epita.fr>
10834 Fix Autoconf PR/209.
10835 Also reported by Frank Denis.
10837 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
10839 2002-02-07 Akim Demaille <akim@epita.fr>
10841 Fix Autoconf PR/207:
10842 AC_PREFIX_PROGRAM fails with dashed program names
10844 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
10845 variable when looking for the prefix program.
10846 Now it also works for shell variables.
10848 2002-02-07 Akim Demaille <akim@epita.fr>
10850 * doc/autoconf.texi (Limitations of Builtins): More about
10851 case/esac.

10855 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
10856 case/esac, some shells don't support it.
10857 Reported by Zack Weinberg.
10858 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
10860 2002-02-06 Akim Demaille <akim@epita.fr>
10862 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
10863 sure not to introduce newlines in at_groups.
10864 * lib/autotest/Makefile.am (autotest.m4f): Typo.
10866 2002-02-06 Akim Demaille <akim@epita.fr>
10868 * tests/torture.at (Configuring subdirectories): Skip if aclocal
10869 is not available.
10871 2002-02-05 Paul Eggert <eggert@twinsun.com>
10873 * doc/autoconf.texi (Specific Compiler Characteristics):
10874 Describe HP-UX cc bug workaround more accurately.
10875 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
10876 not unsigned long.
10877 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
10878 cross-compilers, too. This undoes some of the most recent change
10879 to this file.
10881 2002-02-05 Akim Demaille <akim@epita.fr>
10883 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
10884 to make sure they are up to date when `check' is run.
10886 2002-02-05 Akim Demaille <akim@epita.fr>
10888 * doc/autoconf.texi (Making testsuite Scripts): Document

10891 2002-02-05 Akim Demaille <akim@epita.fr>
10893 * lib/freeze.mk: New.
10895 2002-02-05 Akim Demaille <akim@epita.fr>
10897 Implement `autom4te --freeze'.
10899 * bin/autom4te.in (&freeze): New.
10900 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
10901 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
10903 2002-02-05 Akim Demaille <akim@epita.fr>
10905 * bin/autom4te.in (&parse_args): Implement `frozen files are
10906 optional are the sum of the previous files on the command line'.
10907 Also, pass `--reload-state=' on them, so...
10908 (handle_m4): don't.
10909 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
10910 (M4sh): Rely on M4sugar.
10911 (Autotest, M4sh, M4sugar): Use frozen files.
10913 2002-01-31 Akim Demaille <akim@epita.fr>
10915 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
10916 * doc/autoconf.texi (Initializing configure): Adjust.
10918 2002-01-30 Akim Demaille <akim@epita.fr>
10920 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
10921 alphanumeric to `-' instead of `_'.
10923 2002-01-30 Akim Demaille <akim@epita.fr>
10925 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
10926 for plain code, the other for cross-compilation code. The latter
10927 is now run with GCC only.
10928 * doc/autoconf.texi (Compilers and Preprocessors): New.
10930 2002-01-30 Akim Demaille <akim@epita.fr>
10932 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
10933 values.
10934 * doc/autoconf.texi (Initializing configure): Explain how to
10935 change AC_INIT default values.
10937 2002-01-29 Akim Demaille <akim@epita.fr>

10940 so that aclocal 1.4 works.
10941 Reported by Alexandre Duret-Lutz and Larry Schmitt.
10943 2002-01-28 Akim Demaille <akim@epita.fr>
10945 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
10946 needs an argument.
10948 2002-01-28 Akim Demaille <akim@epita.fr>
10950 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
10951 AUTOTEST_PATH *after* it was set.
10952 Don't put `.' in the PATH: the user should be precise and `./' if
10953 needed. In addition, given that the test suite does some `cd', if
10954 `.' is in the path, the `tested programs' sections will report
10955 programs found in the test suite's directory, while during the
10956 tests (performed in their own directory), these programs are no
10957 longer visible. In other words, the results is confusing and
10958 useless.
10959 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
10961 2002-01-24 Akim Demaille <akim@epita.fr>

10970 2002-01-24 Akim Demaille <akim@epita.fr>
10972 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.

10989 Automake.
10991 2002-01-24 Akim Demaille <akim@epita.fr>
10993 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
10994 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
10995 Reported by Geir Ove Myhr.
10997 2002-01-21 Akim Demaille <akim@epita.fr>
10999 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
11001 2002-01-21 Akim Demaille <akim@epita.fr>
11003 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
11004 message on invalid options.
11005 * bin/autom4te.in (parse_args): Don't use
11006 Autoconf::General::getopt with non valid options.
11008 2002-01-17 Jim Meyering <meyering@lucent.com>
11010 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
11011 $ac_cv_exeext so we don't use an old, invalid, cached value.
11013 2002-01-11 Akim Demaille <akim@epita.fr>
11015 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
11016 Meyering.

11018 limitation.
11019 (Particular Functions): Document AC_FUNC_STRNLEN.

11022 2002-01-06 Akim Demaille <akim@epita.fr>
11024 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
11025 package.m4, since is really depends upon configure.ac, not
11026 configure.
11027 * doc/autoconf.texi (testsuite Scripts): Adjust.
11028 * tests/Makefile.am (package.m4): New.
11029 EXTRA_DIST it since its a source.
11031 2002-01-06 Akim Demaille <akim@epita.fr>
11033 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
11034 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
11035 and PACKAGE_BUGREPORT from here...
11036 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
11037 arguments.
11038 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
11039 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
11040 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
11041 * tests/tools.at (autoheader): Adjust.
11042 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
11044 2002-01-06 Akim Demaille <akim@epita.fr>

11050 * doc/autoconf.texi (Output): Improved wording regarding use of
11051 AC_OUTPUT.

11056 * doc/autoconf.texi (Function Portability): Add notes on sscanf
11057 sometimes needing writable input.
11059 2001-12-17 Jim Meyering <meyering@lucent.com>
11061 * doc/autoconf.texi (New Macros): Tweak wording.
11063 2001-12-14 Akim Demaille <akim@epita.fr>
11065 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
11066 trailing files, don't apply `-rf' to files which might not be
11067 created by configure (core, core.*, and *.core), but just `rm -f'.
11068 Suggested by Jonathan Kamens.
11070 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
11072 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
11074 2001-12-14 Akim Demaille <akim@epita.fr>
11076 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
11078 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

11094 2001-12-12 Kevin Ryde <user42@zip.com.au>
11096 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
11097 forbidden file descriptors table.
11099 2001-11-26 Akim Demaille <akim@epita.fr>
11101 * bin/autoscan.in (%c_keywords): Build it at top level.
11102 Map to 1 in order to simplify its uses.
11104 2001-11-26 Akim Demaille <akim@epita.fr>
11106 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
11107 Remove $filepath, useless.
11108 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
11109 variables, they are really part of the tokens.
11110 Split the input line on spaces and then look for tokens.
11111 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
11112 because of `lex$U.$(OBJEXT)'.
11113 (&scan_files): Use "@list" instead of join.
11114 * doc/Makefile.am (CLEANFILES): Add *.fns.
11116 2001-11-26 Akim Demaille <akim@epita.fr>
11118 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
11119 Remove, replaced by...
11120 * tests/wrappl.in: Be common for all the Perl executables.
11121 In particular autoscan and autoheader want -I.
11122 * configure.ac: Adjust.
11123 * lib/autoscan/headers: errno.h is portable.
11125 2001-11-26 Akim Demaille <akim@epita.fr>
11127 * bin/autoscan.in (used): New.
11128 Use it.
11130 2001-11-26 Akim Demaille <akim@epita.fr>
11132 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
11133 directives.
11134 (&scan_sh_file): Remove a duplicate pattern.
11135 (&check_configure_ac): Use long options.
11136 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
11138 2001-11-26 Akim Demaille <akim@epita.fr>
11140 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
11141 Before, having a line containing the opening of a multi line
11142 comment made the whole line be ignored.
11144 2001-11-26 Akim Demaille <akim@epita.fr>
11146 * doc/autoconf.texi (Using an Autotest Test Suite): New.
11147 (testsuite Scripts): Be one of its subsection.
11148 (Autotest Logs): New.
11150 2001-11-26 Akim Demaille <akim@epita.fr>
11152 Test groups are now run two directories deeper.
11154 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
11155 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
11156 at_top_builddir.
11157 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
11158 top_srcdir, builddir and top_builddir.
11159 Use `at_*dir' relatively to the directory containing the
11160 suite, use `*dir' when relatively to the current group dir.
11162 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
11164 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
11165 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
11166 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
11167 spelling errors.
11169 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
11171 * doc/autoconf.texi (Using System Type): Add an example of `case
11172 $host' usage so people quit using `case $target' everywhere.
11174 2001-11-22 Akim Demaille <akim@epita.fr>
11176 * doc/autoconf.texi (Installation Directory Variables): Englishoes
11177 spotted by Jim Meyering.
11179 2001-11-16 Paul Eggert <eggert@twinsun.com>
11181 This patch implements a `long double' suggestion by Oliver Kiddle.
11183 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
11184 static, to catch errors if the value isn't known at compile-time
11185 and the compiler supports dynamic arrays. Change its name from
11186 `_array_' to `test_array' to avoid potential name clashes.
11187 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
11188 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
11189 better than double. Catch a bug in GCC 2.95.2 x86.
11190 * doc/autoconf.texi (C Compiler): Document the above.
11191 * NEWS: Likewise.
11193 2001-11-13 Akim Demaille <akim@epita.fr>
11195 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
11196 hand.
11197 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
11199 2001-11-13 Akim Demaille <akim@epita.fr>
11201 * lib/autotest/general.m4 (AT_INIT): After having run the test
11202 group, go back to the initial directory, not to at_suite_dir.
11204 2001-11-13 Akim Demaille <akim@epita.fr>
11206 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
11207 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
11208 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
11209 option.
11210 (AT_CHECK_CONFIGURE): Use absolute paths.
11211 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
11212 The problem is still the old one: there is no means in M4 (that I
11213 know about) to create a defining macro, because there is no means
11214 to create `$1' etc., therefore, the defining macro ``swallows''
11215 all the arguments meant to the defined macro.
11217 2001-11-13 Akim Demaille <akim@epita.fr>
11219 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
11220 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
11221 configure.ac.
11222 * tests/aclocal.m4: Remove, as it is no longer used.
11224 2001-11-13 Akim Demaille <akim@epita.fr>
11226 * lib/autotest/general.m4: Change `tests?' into `groups?' in
11227 variable names when referring to a single test group, or to
11228 `suite' when referring to the whole test suite.
11229 `at_last_test' is removed: m4 compute at_format itself.
11230 (at_stdout, at_stder1, at_stderr): New variables.
11231 (AT_CHECK): Use them.
11233 2001-11-13 Akim Demaille <akim@epita.fr>
11235 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
11236 in PATH.
11237 Create `testsuite.dir/003/run' instead of `testsuite.003'.
11238 Do it as soon as a test fails, don't wait till the end of the test
11239 suite.
11240 Don't remove $as_me.[0-9]*, since these files no longer exist.
11242 2001-11-13 Akim Demaille <akim@epita.fr>
11244 * tests/tools.at: Use absolute paths, since we are no longer run
11245 in place.
11247 2001-11-13 Akim Demaille <akim@epita.fr>
11249 Now that tests are running in their own private dir, there is no
11250 need to list the files to remove at the end of tests groups.
11252 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
11253 (AT_data_files, at_data_files): Remove.
11254 (AT_CLEANUP, AT_DATA): Simplify.
11255 (AT_INIT): Adjust.
11256 Remove the group dir if !debug && !failed.
11257 * tests/atspecific.m4: Adjust.
11259 2001-11-13 Akim Demaille <akim@epita.fr>
11261 Start a new layout for Autotest: `testsuite' creates
11262 `testsuite.dir' in which the at-check-line etc. files are to be
11263 found, and `testsuite.dir/003' where the test group 3 is run.
11265 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
11266 at_check_line_file, at_format, at_test_normalized, at_group_dir
11267 are new variables.
11268 Create the directories.
11269 Use absolute paths for at- files.
11270 (AT_CHECK): Adjust.
11272 2001-11-11 Michael Matz <matz@kde.org>
11274 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
11275 (m4_car2): New.
11276 (m4_car): Properly quote arguments.
11278 2001-11-13 Akim Demaille <akim@epita.fr>
11280 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
11281 with stricter rules on LIBOBJS.
11283 2001-11-12 Paul Eggert <eggert@twinsun.com>
11285 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
11286 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
11287 __PROTOTYPES too.
11289 2001-11-12 Akim Demaille <akim@epita.fr>
11291 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
11293 2001-11-12 Akim Demaille <akim@epita.fr>
11295 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
11296 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
11297 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11298 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
11299 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
11300 specify to what the macro should be defined (typically to 1).
11302 2001-11-12 Akim Demaille <akim@epita.fr>
11304 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
11305 From Jim Meyering.
11307 2001-11-12 Akim Demaille <akim@epita.fr>
11309 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11310 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
11311 definition used by Automake where LEX is +/- "${missing} lex" and
11312 `missing' itself contains variables.
11314 2001-11-12 Akim Demaille <akim@epita.fr>
11316 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
11317 Now that M4sh pushes BODY, the comments were output at the end of
11318 the test suites.
11320 2001-11-08 Akim Demaille <akim@epita.fr>
11322 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
11323 that we can trace macros from aclocal.m4.
11324 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
11325 obsoleted, and redirect to the former anyway.
11326 Reported by Ralf Corsepius.
11328 2001-11-08 Akim Demaille <akim@epita.fr>
11330 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
11331 processed only if present.
11332 * tests/torture.at (Configuring subdirectories): Use autoreconf
11333 instead of successive calls to autoconf.
11334 Add a nonexistent subdirectory to exercise the patch above.
11335 Reported by Ralf Corsepius.
11337 2001-11-08 Kevin Ryde <user42@zip.com.au>
11339 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
11340 doesn't accept .S files.
11342 2001-11-07 Akim Demaille <akim@epita.fr>
11344 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
11345 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
11346 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
11347 * bin/autom4te.in (warn_forbidden): New.
11348 (handle_output): Use it.
11349 Read m4_pattern_forbid with messages.
11351 2001-11-05 Akim Demaille <akim@epita.fr>
11353 * bin/autom4te.in (--normalize): Remove.
11354 * lib/autom4te.in: Adjust.
11356 2001-11-05 Akim Demaille <akim@epita.fr>
11358 * tests/Makefile.am (testsuite): Rename this target as...
11359 ($(TESTSUITE)): this.
11360 From Nicolas Joly.
11362 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
11364 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
11365 the --prefix option, also remove it's argument.
11367 2001-11-05 Akim Demaille <akim@epita.fr>
11369 * doc/autoconf.texi (testsuite Invocation): Update.
11370 (Writing testsuite.at): Update.
11372 2001-11-03 Akim Demaille <akim@epita.fr>
11374 * doc/autoconf.texi: s/@code/@command/ where appropriate.
11376 2001-11-03 Akim Demaille <akim@epita.fr>
11378 * lib/Autom4te/General.pm: (&catfile, &canonfile)
11379 (&file_name_is_absolute): New, wrappers around routines from
11380 File::Spec.
11381 Use and export them.
11382 (&find_configure_ac): Optionally take a directory where to look at.
11383 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
11384 the arguments.
11385 Default @ARGV to `.', not find_configure_ac.
11386 (&autoreconf): Argument is a directory.
11387 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
11388 * doc/autoconf.texi (autoreconf Invocation): Update.
11390 2001-11-03 Akim Demaille <akim@epita.fr>
11392 * lib/Autom4te/General.pm (@export_vars, @export_subs)
11393 (@export_forward_subs): New.
11394 Add basename, dirname, and fileparse.
11395 (@EXPORT): Adjust.
11396 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
11397 Don't look for aclocal flags if we already know aclocal is not
11398 used.
11399 Move aclocal.m4t only if it exists.
11400 Reported by Ezra Peisach.
11402 2001-11-03 Akim Demaille <akim@epita.fr>
11404 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
11405 passed on command line, defaulting to ./configure.ac if present.
11406 (&maybe_autoreconf, File::Find): Remove, unused.
11407 (&autoreconf): If autoconf is not used, don't try to trace.
11409 2001-11-02 Akim Demaille <akim@epita.fr>
11411 * configure.ac: Bump to 2.52g.
11413 2001-11-02 Akim Demaille <akim@epita.fr>
11415 Version 2.52f.
11417 2001-11-02 Akim Demaille <akim@epita.fr>
11419 * config/config.guess, config/config.sub, doc/standards.texi:
11420 * config/lispdir.m4: Update from masters.
11421 * configure.ac: Bump to 2.52f.
11423 2001-11-02 Akim Demaille <akim@epita.fr>
11425 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
11426 Don't run aclocal when aclocal.m4 is not from aclocal.
11427 From Ezra Peisach.
11428 Don't run libtoolize and gettextize if --install is not given.
11430 2001-11-01 Paul Eggert <eggert@twinsun.com>
11432 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
11433 be invoked before _AS_LINENO_PREPARE.
11434 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
11435 than character ranges.
11437 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
11438 invoking AS_BASENAME. Set the locale variables to 'C' if
11439 possible, as POSIX requires this to get the traditional
11440 behavior.
11441 * doc/autoconf.texi (Special Shell Variables): Describe the above.
11443 2001-10-31 Paul Eggert <eggert@twinsun.com>
11445 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
11446 with {}, as that triggers a bug in Bash 2.05.
11448 (_AS_LINENO_PREPARE): Use Sed rather than
11449 Awk. Fix the sed prepass to work even if there are multiple
11450 instances of $LINENO on the same line. Do not substitute for
11451 other variables like $LINENOT. Do not check file dates; such a
11452 check is unreliable on sufficiently fast machines, and removing
11453 the check makes the code simpler and more reliable. Check for
11454 output and chmod failures.
11456 * doc/autoconf.texi (Special Shell Variables): Document
11457 the above.
11459 2001-10-31 Akim Demaille <akim@epita.fr>
11461 * tests/Makefile.am (atconfig): Remove this target, Automake
11462 handles it now.
11464 2001-10-31 Akim Demaille <akim@epita.fr>
11466 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
11467 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
11468 provided, while it is optional.
11469 * configure.ac: Adjust.
11471 2001-10-26 Paul Eggert <eggert@twinsun.com>
11473 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
11474 lib/Autom4te/Struct.pm:
11475 Require Perl 5.005_03 instead of just 5.005, as some tests fail
11476 with 5.005_02.
11478 * doc/autoconf.texi (Special Shell Variables): Document some
11479 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
11481 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
11482 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
11483 eval $LINENO is not portable in practice.
11485 2001-10-24 Akim Demaille <akim@epita.fr>
11487 * lib/Autom4te/General.pm (backname): New.
11489 2001-10-24 Akim Demaille <akim@epita.fr>
11491 * m4/: Remove, merged into...
11492 * config/: here.
11494 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
11496 * doc/autoconf.texi (Shellology): Mention the problems with bash
11497 2.05's use of ANSI quoting in its `set' builtin.
11499 2001-10-22 Paul Eggert <eggert@twinsun.com>
11501 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
11502 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
11503 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
11504 POSIX decided to standardize on the int flavor of strerror_r.
11505 Always do char* test, as there's no reason not to.
11506 Assign to a char* var, to catch strerror_r that returns int*.
11508 * doc/autoconf.texi (Particular Functions):
11509 Document the above changes. Also, document the fact that
11510 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
11512 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
11514 2001-10-20 Akim Demaille <akim@epita.fr>
11516 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
11517 the executable was missing from the log.
11519 2001-10-20 Akim Demaille <akim@epita.fr>
11521 * lib/Autom4te/General.pm (&update_file): If destination is
11522 unchanged, remove the source.
11523 (&up_to_date_p): Don't be verbose, be debug.
11524 * bin/autoreconf.in: No longer support --m4dir.
11525 (&autoreconf): Display the full path of the configure.ac we are
11526 studying.
11527 Trace it only once.
11528 Be sure to honor --force with gettextize.
11529 Always run aclocal.
11530 * doc/autoconf.texi: Adjust.
11532 2001-10-20 Akim Demaille <akim@epita.fr>
11534 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
11535 Remove, dead.
11536 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
11537 `intl' is already present, as it refuses unless --force.
11538 (&parse_args): Use -I, --include instead of the old Autoconf
11539 options.
11540 ($localdir, $autoconf_dir): Remove.
11541 (@include): New.
11542 (&maybe_autoreconf): New, to preserve $_ for File::Find.
11544 2001-10-19 Jens Petersen <petersen@redhat.com>
11546 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
11547 * doc/autoconf.texi (Particular Programs): Likewise.
11549 2001-10-19 Akim Demaille <akim@epita.fr>
11551 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
11552 file in @configure_input@.
11553 Don't mention `automatically' in addition to `generated'.
11554 * tests/torture.at (#define header templates): Adjust.
11556 2001-10-19 Akim Demaille <akim@epita.fr>
11558 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
11559 comment, explain how to install automatic mode selection.
11560 From Russ Allbery.
11562 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
11564 * bin/autoreconf.in (autoreconf): Display the path to the
11565 configure.ac being studied.
11567 2001-10-18 Paul Eggert <eggert@twinsun.com>
11569 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
11570 long, to work around a bug in the HP C compiler version HP92453-01
11571 B.11.11.23709.GP.
11573 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
11574 (AS_BASENAME_EXPR): New macro.
11575 (AS_BASENAME_SED): Do not assume GNU sed semantics.
11576 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
11577 and fall back on 'sed' only if the other two fail. This makes
11578 AS_BASENAME act more like AS_DIRNAME.
11579 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
11580 contains white space.
11581 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
11582 Use AS_DIRNAME, since I think it's now DOS-friendly.
11583 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
11584 Allow "dirname //FOO" to return either / or //, as POSIX allows
11585 either behavior.
11587 2001-10-10 Akim Demaille <akim@epita.fr>
11589 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
11590 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
11591 From Eric Sharkey.
11593 2001-10-10 Akim Demaille <akim@epita.fr>
11595 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

11850 * tests/fortran.at (GNU Fortran 77): there.
11851 * doc/autoconf.texi (autoconf Invocation): Fix the example:

11861 enough.

12048 Do not pass a first argument with leading '-'
12049 to expr, by parenthesizing initial integers that might be negative.
12051 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
12052 now merely checks whether it is an error to pass an argument
12053 to getpgrp.
12055 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
12056 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
12057 whether it is a (compile-time) error to pass an argument to
12058 getpgrp. This simpler test supports the revised documentation,
12059 and is all that AC_FUNC_GETPGRP's users really need.
12061 2001-09-18 Akim Demaille <akim@epita.fr>
12063 * doc/autoconf.texi (Limitations of Make) <$<>: New.
12065 2001-09-18 Akim Demaille <akim@epita.fr>
12067 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
12068 `{}'.
12069 * lib/autotest/general.m4 (AT_INIT): Adjust.
12071 2001-09-18 Paul Wagland <paul@wagland.net>
12073 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
12074 correctly.
12075 Add test for AS_BASENAME.
12076 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
12077 added test. It now correctly handles /1/2/3/, returning '3' not ''.
12078 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
12079 * tests/base.at: Fixed the expected responses. The old ones were
12080 one line out...
12081 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
12082 the documentation claims it should (and how it behaved in 2.13).
12084 2001-09-18 Akim Demaille <akim@epita.fr>
12086 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
12087 the AC_CONFIG_COMMANDS invocation.
12088 This also solves the name clash problems.
12089 Don't set the package's ID.
12090 * lib/m4sugar/Makefile.am (version.m4): Revamp.
12091 No longer to be shipped.
12092 (version.in): Remove.
12093 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
12094 * lib/autoconf/status.m4: Adjust.
12095 Use `m4_PACKAGE_STRING'.
12096 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
12097 the only optional argument is the name of the test suite.
12098 Expect `package.m4' to define the package signature.
12099 * lib/autom4te.in (Autotest): Add `package.m4?'.
12100 * tests/Makefile.am (package.m4): New.
12101 * tests/suite.at: ifnames is a victim.
12103 2001-09-18 Akim Demaille <akim@epita.fr>
12105 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
12106 AC_LIBSOURCE, AC_CONFIG_FILES.
12107 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
12108 program version string doesn't match the package's.
12109 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
12110 after `(cached)'.
12112 2001-09-17 Paul Eggert <eggert@twinsun.com>
12114 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12115 Allow expression to return any value that can fit into unsigned long
12116 (not int, as before). Check for output errors.
12118 2001-09-17 Bruno Haible <haible@ilog.fr>
12120 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12121 Always include <stdio.h> and <stdlib.h>. Evaluate
12122 the expression in an extra function before these includes. Call
12123 fprintf "%d" only after ensuring the argument is of type 'int'.
12124 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
12126 2001-09-17 Paul Eggert <eggert@twinsun.com>
12128 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
12129 or CFLAGS=-O5. In that case, the linker has a relaxed view of
12130 fatal errors, and AC_CHECK_LIB causes it to include libraries even
12131 when they don't exist.
12133 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
12134 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
12135 need it.
12137 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
12138 version with the version used by fileutils 4.1, except use
12139 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
12140 we don't need it.
12142 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
12144 2001-09-13 Akim Demaille <akim@epita.fr>
12146 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
12147 _first_.
12148 Reported by Gerrit P. Haase.
12150 2001-09-13 Akim Demaille <akim@epita.fr>
12152 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
12153 m4_defn'ing is valid.

12159 Use it.

12168 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
12169 Likewise.
12170 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
12171 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
12172 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
12173 AT_tests_all for consistency.
12174 Set at_victims.
12175 (AT_VICTIMS): Similar to AT_KEYWORDS.
12176 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
12178 2001-09-13 Akim Demaille <akim@epita.fr>
12180 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
12182 2001-09-13 Akim Demaille <akim@epita.fr>
12184 * lib/autotest/general.m4 (AT_INIT): Create and remove
12185 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
12186 test suites can cohabit.
12188 2001-09-13 Akim Demaille <akim@epita.fr>
12190 * tests/mktests.sh: Don't output banners for empty test files.
12192 2001-09-13 Akim Demaille <akim@epita.fr>
12194 Test suites can be run independently of configure.

12197 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.
12198 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust: AC_SUBST

12229 (AT_CLEANUP_FILE_IFELSE, AT_CLEANUP_FILE): Rename as...

12236 (m4_list_append): Remove.
12238 Spread a few keywords in the Autoconf test suite.
12240 2001-09-10 Akim Demaille <akim@epita.fr>
12242 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

12245 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

12256 (AC_CHECK_PROG & AC_CHECK_PROGS): Use PATH_SEPARATOR.
12258 2001-09-07 Akim Demaille <akim@epita.fr>
12260 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
12261 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
12262 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
12263 related variables into `at_package_*'.

12273 Move toward possibly stand-alone test suites.
12275 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
12276 in addition, it introduces useless differences in logs.
12277 (AT_INIT): Let atconfig and atlocal be both optional.
12278 Adjust PATH computation.
12279 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.
12281 2001-09-07 Akim Demaille <akim@epita.fr>
12283 * lib/autoconf/Makefile.am (autoconf.m4f): Depends upon

12288 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'

12290 From Uwe Seimet.
12292 2001-09-05 Akim Demaille <akim@epita.fr>
12294 * bin/autom4te.in: --language is -l, not -s.
12296 2001-09-05 Akim Demaille <akim@epita.fr>
12298 Be ready to handle filenames as stupid as `dnl.at', for if even
12299 the maintainer is dumb enough to do that...
12301 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
12302 excellence in M4 quotation: consider `__file__' is active.
12304 And BTW, when invoking m4, pass the --include in the right order:
12305 the wrong one.
12307 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
12308 4m.
12310 2001-09-05 Akim Demaille <akim@epita.fr>
12312 * lib/Autom4te/XFile.pm: New lib file.
12313 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
12314 * bin/autoheader.in: Use it.
12316 2001-09-05 Akim Demaille <akim@epita.fr>
12318 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff

12328 * doc/autoconf.texi (autoscan Invocation): Adjust.
12330 2001-09-05 Akim Demaille <akim@epita.fr>
12332 CVS GNU M4 doesn't like `undefine(undefined)'.
12334 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
12335 New, extracted from main.
12336 Use IO::File wherever possible.
12337 (input.m4): Be constant, use -I instead of hard coding $tmp.
12338 Therefore be a quoted heredoc.
12339 Don't invoke `_au_disable', since ac was not loaded, but just
12340 `unm4.m4'.
12342 2001-08-31 Akim Demaille <akim@epita.fr>
12344 Version 2.52d.
12346 2001-08-31 Akim Demaille <akim@epita.fr>

12349 previous patch.

12356 Reported by Nicolas Joly.
12358 2001-08-31 Akim Demaille <akim@epita.fr>
12360 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
12361 (Making testsuite Scripts): Update.
12363 2001-08-31 Akim Demaille <akim@epita.fr>
12365 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
12367 2001-08-31 Akim Demaille <akim@epita.fr>
12369 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
12370 (testsuite Scripts): There is no such thing as `atconfig.in'.
12371 And actually one diagram is missing: test suite runtime.
12373 2001-08-31 Akim Demaille <akim@epita.fr>
12375 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
12376 inverse order.
12378 2001-08-31 Akim Demaille <akim@epita.fr>
12380 * bin/autoupdate.in (@include): `installcheck' revealed the path
12381 to m4sugar was lacking!
12383 2001-08-31 Akim Demaille <akim@epita.fr>
12385 * man/Makefile.am (.x.1): We really have to pass
12386 autom4te_perllibdir.
12388 2001-08-31 Akim Demaille <akim@epita.fr>
12390 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
12391 debug scripts, in particular passing explicitly listed tests to
12392 run is stupid.
12394 2001-08-31 Akim Demaille <akim@epita.fr>
12396 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
12397 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
12398 Use directly autom4te, not autoconf.
12399 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
12401 2001-08-31 Akim Demaille <akim@epita.fr>
12403 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
12404 * bin/autoheader.in (%symbol): Strip arguments of macros.

12410 2001-08-31 Akim Demaille <akim@epita.fr>
12412 * bin/autom4te.in (&parse_args): Die on unknown languages.
12413 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
12414 need for autoconf.
12415 Promote --include over --macrodir and other obsolete options.
12417 2001-08-31 Akim Demaille <akim@epita.fr>
12419 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
12420 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
12421 * bin/autom4te.in ($autoconf): Pass --force.
12422 `print $out' doesn't print `$_' but `$out'.
12423 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
12424 (autoheader): Pass --force since the test suite goes too fast for
12425 the time stamps.
12426 Adjust to the new autoheader messages.
12428 2001-08-31 Akim Demaille <akim@epita.fr>
12430 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
12431 Check the completeness of the #template.
12432 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
12433 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
12434 invocation.
12436 2001-08-31 Akim Demaille <akim@epita.fr>
12438 * lib/Autom4te/General.pm (&find_file, &update_file): New.
12439 * bin/autoupdate.in, bin/autoheader.in: Adjust.
12440 Drop AC_MACRODIR dead for real.
12441 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
12442 `autoheader: `config.hin' is created'.
12443 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
12445 2001-08-31 Akim Demaille <akim@epita.fr>
12447 * bin/autoheader.in: Rewrite in Perl.
12448 * tests/autoheader: Adjust.
12450 2001-08-31 Akim Demaille <akim@epita.fr>
12452 * bin/autoconf.in (--include, -I): New option.
12453 Map --localdir, --autoconf-dir onto it.
12454 Forward autom4te's options instead of interpreting them.
12455 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
12456 There is no such envvar since the inception of autom4te.cfg.
12457 * bin/autom4te.in (&parse_args): Uniquify `@include'.
12458 * bin/autoupdate.in: Adjust, and perform more control.
12459 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
12460 * tests/autoconf: Dittowise.
12462 2001-08-31 Akim Demaille <akim@epita.fr>
12464 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
12465 * bin/autom4te.in (&find_file): Support `FILE?' standing for
12466 optionally `FILE'.
12467 Use -e, not -f, since /dev/null for instance is OK.
12468 (&parse_args): Adjust.
12469 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
12471 2001-08-31 Akim Demaille <akim@epita.fr>
12473 * configure.ac: Also find tested executables in bin.
12474 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
12475 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
12476 installed peer executables, only PATH is allowed to resolve it.
12477 Pass `autoconf_dir' via options, not via invisible envvars.
12478 * lib/Autom4te/General.pm (&find_peer): Remove.
12479 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
12480 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
12481 * man/Makefile.am: Let help2man rely on PATH instead of trying to
12482 find the executables for it.
12483 * tests/Makefile.am: Major cleanup. Too lazy to document...
12484 * tests/atlocal.in: Remove all the obscure envvar manipulations.
12485 We only need PERL.
12486 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
12487 indeed related to running the test suite, while passing
12488 --autoconf-dir and others is related to running non installed
12489 Autoconf executables. So don't do that, leave it to...

12688 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
12689 the name of the directory they're in, instead of the filename,

13064 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
13065 magic values from an object file when cross-compiling.
13066 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
13068 2001-08-10 Akim Demaille <akim@epita.fr>
13070 * bin/autom4te.in (&handle_output): Don't use `grep' with side
13071 effects.
13072 Suggested by Russ Allbery.
13074 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
13076 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
13077 current $prefix to the sub-configures.
13079 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
13081 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
13082 extension (needed on BeOS). Reported by Guido van Rossum.
13084 2001-08-09 Akim Demaille <akim@epita.fr>
13086 * bin/autom4te.in ($icache): Load it only if older than autom4te.
13088 2001-08-07 Akim Demaille <akim@epita.fr>
13090 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
13091 removed.
13092 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
13093 No need to remove the files before and after the each test, before
13094 each test and at the end of the suite is enough.
13095 Display only the children `times', not the shell's.
13096 If the test failed or was skipped, at-times is not available.
13098 2001-08-07 Akim Demaille <akim@epita.fr>
13100 Always produce testsuite.log, including when there are no
13101 failures. This helps getting information on skipped tests, and
13102 duration of the tests. Err, implement the latter btw.
13104 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
13105 Dump information on the first run of each test.
13106 (AT_CLEANUP): Create `at-times' containing the duration of the
13107 test group.
13109 2001-08-07 Akim Demaille <akim@epita.fr>
13111 The use of `dumpstat' revealed that `len' was used although it
13112 should not. m4_text_wrap was using it, but in the Autoconf world
13113 where it is legal. Hence (i) test M4sh in its own world, not
13114 Autoconf's, and (ii), ahem, fix the bug :)
13116 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
13117 does not like `' instead of [].
13118 (AT_INIT): Forbid `^_?AT_'.
13119 And don't output such tokens.
13120 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
13121 `script.as', and `autom4te.cache'.
13122 Remove `empty' and `macro' which are no longer used.
13123 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
13124 * tests/m4sugar.at: Use it.
13125 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
13127 2001-08-07 Akim Demaille <akim@epita.fr>
13129 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
13131 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
13133 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
13135 2001-08-04 Akim Demaille <akim@epita.fr>
13137 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
13138 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
13139 AC_TRY_LINK.
13140 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
13141 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
13142 (AC_F77_MAIN): Likewise.
13144 2001-08-04 Akim Demaille <akim@epita.fr>
13146 Don't rely on M4sugar outputting the patterns in files, since we
13147 might process the output _without_ running m4, hence without these
13148 files.
13150 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
13151 * bin/autom4te.in (@Request::includes): Remove, unused.
13152 (@Request::source): Rename as...
13153 (@Request::input): this.
13154 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
13155 (&handle_output): Fetch the patterns from the traces.
13156 `$forbidden' and `$allowed' are constant: use m//o.
13157 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
13158 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
13160 2001-08-04 Akim Demaille <akim@epita.fr>
13162 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
13163 autoconf', i.e., in addition to caching traces, cache the output.
13165 * bin/autom4te.in (Request::cache): Rename as...
13166 (Request::id): this.
13167 ($cache, $icache, $tcache, $ocache): New.
13168 (&handle_m4): Save M4 output in the cache instead of $tmp.
13169 (&handle_output): Adjust.
13170 (&up_to_date_p): Check that the output cache is up to date too.
13171 (top level): Run `&handle_m4' iff force or the cache is invalid.
13172 Run `&handle_output' if the output cache is more recent.
13174 2001-08-04 Akim Demaille <akim@epita.fr>
13176 * bin/autom4te.in ($force): New.
13177 (&parse_args, &print_usage): -f, --force is a new option.
13178 (&handle_output): CPP directives might have spaces after `#'.
13179 (&parse_args): The first file only can be frozen.
13181 2001-08-04 Akim Demaille <akim@epita.fr>
13183 Don't let autom4te compute the `include' traces several times:
13184 first check that the trace cache file is up to date, and then
13185 compare its timestamp with that of the output.
13187 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
13188 the preamble. Don't require 5.005 as Autom4te::General does it,
13189 and better yet (use `use', not `require'!).
13190 * lib/Autom4te/Struct.pm: Rename the last occurrences of
13191 Class::Struct as Autom4te::Struct.
13192 * lib/Autom4te/General.pm (File::stat): Use it.
13193 (&mtime): New, export it.
13194 * bin/autom4te.in: Use it.
13195 Declare `$req' is invalid if it is outdated.
13196 Don't declare it valid before saving it if something went wrong.
13198 2001-08-04 Akim Demaille <akim@epita.fr>
13200 Autom4te shall not encode Autoconf data, and preselecting traces
13201 must be proposed to the users.
13203 * bin/autom4te.in (@required_trace): Remove.
13204 (@preselect): New.
13205 (&parse_args, &print_usage): -p, --preselect is a new option.
13206 (&up_to_date_p): Adjust.
13207 * bin/autoconf.in: Preselect some Autoconf macros.
13209 2001-08-04 Akim Demaille <akim@epita.fr>
13211 * tests/tools.at (autoconf --trace: user macros): Check traces on
13212 macros invoked without arguments, and macros invoked with multiple
13213 lines arguments.
13215 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
13217 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
13218 arguments.
13220 2001-08-03 Akim Demaille <akim@epita.fr>
13222 * bin/autoconf.in ($@): Work around the usual sh bug.
13223 From Nicolas Joly.
13225 2001-08-03 Akim Demaille <akim@epita.fr>
13227 Clean up the handling of the M4 builtins tracing exception.
13229 * bin/autom4te.in (Request::request): Don't complete M4 builtins
13230 trace requests.
13231 (@m4_builtins): Rename as...
13232 (@m4_builtin): this.
13233 (%m4_builtin_alternate_name): New.
13234 (&parse_args): Complete the trace requests with alternate names.
13235 (&handle_traces): Hence no longer do it here.
13236 (&trace_requests): Remove, unused.
13238 2001-08-03 Akim Demaille <akim@epita.fr>
13240 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
13241 m4_if, and m4_wrap.
13243 2001-08-03 Akim Demaille <akim@epita.fr>
13245 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
13246 (m4_divert_pop): Dump the whole diversion stack when a diversion
13247 mismatch happens.
13248 * bin/autom4te.in (&handle_output): Remember of the first
13249 occurrence of a possibly undefined macro, not the last.
13250 Complain about the possibly undefined macros in the same order as
13251 the appear in the output.
13252 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
13253 * tests/tools.at (autoconf: forbidden tokens, basic)
13254 (autoconf: forbidden tokens, exceptions): No longer sort
13255 autoconf's stderr, as it is now deterministic.
13256 Check that `dnl' is caught.
13258 2001-08-01 Akim Demaille <akim@epita.fr>
13260 * configure.ac: Bump to 2.52c.
13262 2001-08-01 Akim Demaille <akim@epita.fr>

13272 2001-08-01 Akim Demaille <akim@epita.fr>
13274 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
13275 `die'.
13276 (&END): New.
13277 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
13278 `END', as `Autom4te::General::END' will be triggered.
13279 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
13280 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

13672 compiler, not the preprocessor.

13677 earlier if there are.
13679 2001-07-03 Akim Demaille <akim@epita.fr>

13712 provide an alternate 'main' function name, using the 'main' from
13713 the Fortran libraries.

13715 cross-language link tests can be performed successfully.
13716 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
13717 after $LIBS, for consistency; this should be the general rule since

13724 at-stdout and at-stderr instead of removing the newline
13725 from the echo output, which is not guaranteed to work.
13727 2001-06-28 Jens Petersen <petersen@redhat.com>

13793 * doc/autoconf.texi (Redefined M4 Macros): New.
13795 2001-06-23 Akim Demaille <akim@epita.fr>
13797 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): Consider
13798 inttypes.h is missing if it conflicts with sys/types.h, as on IRIX

13836 ./configure --program-suffix=foo produces `transform=s,$$,foo,;',
13837 but some sed choke on multiple `;', and other tools (e.g.,
13838 Automake), include the separator themselves.
13840 * acgeneral.m4 (AC_ARG_VAR): Be sure not to leave extra `;'.
13842 2001-06-19 Tim Van Holder <tim.van.holder@pandora.be>
