991 /bin/printf '%010000x' 123. Problem reported by Arto C. Nirkko
992 via Bruno Haible.
994 2007-04-12 Paul Eggert <eggert@cs.ucla.edu>
996 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
997 AC_CHECK_TYPE, AC_CHECK_TYPES.
998 * doc/autoconf.texi (Generic types): C types must be type-names
999 (the C terminology), not type-ids (the C++ term). C++ types
1000 must not be anonymous.
1001 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
1002 for C++; this drops support for anonymous struct and union types,
1003 which were problematic anyway.
1004 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
1005 for C++.
1007 2007-04-12 Jim Meyering <jim@meyering.net>
1009 * doc/autoconf.texi (Libraries): Typo fix: insert missing "in".

1013 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK): Fix AC_CONFIG_LINKS
1014 to prefer a link source from the build tree, if it exists.
1015 Report by Pallav Gupta <pallavgupta@gmail.com>.
1017 2007-04-11 Paul Eggert <eggert@cs.ucla.edu>
1019 * doc/autoconf.texi (Generic Types): Document the restrictions
1020 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
1021 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
1022 with objects too. Document the restrictions on its use.
1023 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
1024 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
1025 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
1026 works but the latter doesn't, then it's a valid type.
1027 This lets people use function types and so forth.
1028 For C++ there doesn't seem to be a simple solution, so leave it alone.
1029 (AC_CHECK_SIZEOF): Allow argument to be a variable.
1030 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
1031 AC_CHECK_TYPE; that wasn't documented or necessary.
1033 2007-04-11 Stepan Kasal <kasal@ucw.cz>
1035 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

1051 obsolescent. Suggested by Bruno Haible.
1052 * NEWS: Document this.
1054 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
1056 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
1057 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
1058 default still has the problem. Problem reported by Bruce Korb.
1060 2007-03-28 Stepan Kasal <kasal@ucw.cz>
1061 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1074 more pitfalls.
1076 2007-03-23 Paul Eggert <eggert@cs.ucla.edu>
1078 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
1079 checks for unsigned long long int.
1081 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
1083 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
1084 nonstandard grep R.E. escape sequences.
1086 2007-03-17 Jim Meyering <jim@meyering.net>
1088 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
1089 (Limitations of Usual Tools): Also list \< and \>, and mention that
1090 HP-UX's grep, like the one from Solaris, does not support that syntax.
1092 2007-03-09 Stepan Kasal <kasal@ucw.cz>
1094 * doc/autoconf.texi (Specifying Names): `--host' does not
1095 change the build type.
1097 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
1099 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
1100 suggests AC_CONFIG_HEADERS.
1101 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Warn if not using

1107 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Fix typo "__LITLE_ENDIAN__".
1108 Problem reported by Paolo Bonzini in:
1109 http://lists.gnu.org/archive/html/autoconf-patches/2007-02/msg00024.html
1110 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
1111 universal binaries. Problem reported by Elias Pipping.
1113 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
1115 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
1116 * doc/autoconf.texi (C Compiler): Document this. There is a new
1117 extra argument ACTION-IF-UNIVERSAL.
1118 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
1119 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
1120 Reindent for sanity's sake.
1122 2007-02-24 Eric Blake <ebb9@byu.net>
1124 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update
1125 copyright.
1126 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
1127 * lib/autotest/general.m4 (AT_INIT): Likewise.

1132 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
1133 status of rm so we know when it failed.
1134 If cleaning of test dir failed before running the test, warn.
1135 Output the line separator in verbose mode before the warning
1136 to make clear the warning belongs to the following test.
1138 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>

1153 carriage return.
1154 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
1155 with traditional Awk and begin.
1156 * tests/torture.at (Limitations of Builtins): Document the problem

1190 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
1192 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
1193 latest version.
1194 (Shell Substitutions): Note problems with @{var:=value} etc.
1195 Add a new section for problems with @{#var} etc. Problem noted
1196 by Ralf Wildenhues. See:

1199 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1201 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
1202 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
1203 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
1204 substitution will still be done by the special code.
1205 Report by Jim Meyering.
1207 * doc/autoconf.texi (File System Conventions): Mention that
1208 $PATH_SEPARATOR is for the build system only.

1220 Report against Automake by Patrick Welche.
1222 2007-01-15 Stepan Kasal <kasal@ucw.cz>
1224 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
1226 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1228 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
1229 early on the reader side, drop stderr of the input to avoid
1230 `broken pipe' error output; this may happen even with shell
1231 builtin `echo' of some bash versions. Reports by Ian Macdonald
1232 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
1234 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1236 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

1244 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
1246 Fix some wording problems noted by Paolo Bonzini in:
1247 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
1248 * doc/autoconf.texi (Signed Overflow Examples): Give more
1249 discussion about the allow_superuser_privileges example,
1250 and change it a bit to make things clearer.
1251 (Optimization and Wraparound): Clarify whether the compiler
1252 will generate an infinite loop for the example derived from
1253 Autoconf's mktime test.
1254 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
1255 Also, clarify unsigned multiplication overflow.
1257 2007-01-04 Eric Blake <ebb9@byu.net>
1259 * bin/Makefile.am (RELEASE_YEAR): New macro.
1260 (edit): Use it to supply correct copyright year to scripts.
1261 * bin/autoconf.as (version): Use it.
1262 * bin/autoheader.in ($version): Likewise.
1263 * bin/autom4te.in ($version): Likewise.
1264 * bin/autoreconf.in ($version): Likewise.
1265 * bin/autoscan.in ($version): Likewise.
1266 * bin/autoupdate.in ($version): Likewise.
1267 * bin/ifnames.in ($version): Likewise.
1269 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
1271 * doc/autoconf.texi (Integer Overflow): Revised based on today's
1272 feedback. The most important changes document what happens when
1273 you convert an out-of-range value to a signed integer type, and
1274 say that (sum < a) != (b < 0) reliably detects overflow when sum =
1275 a + b.
1277 * doc/autoconf.texi (Integer Overflow): Greatly expand and
1278 rewrite, taking notions from the recent discussion on the gcc and
1279 autoconf mailing lists; please see
1280 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
1281 and follow the many links.
1282 (Integer Overflow Basics, Signed Overflow Examples):
1283 (Optimization and Wraparound, Signed Overflow Advice):
1284 (Signed Integer Division): New sections.
1286 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
1288 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
1289 preprocessor macro arguments in traced name.
1290 * doc/autoconf.texi (Defining symbols): Document longstanding
1291 support for AC_DEFINE-ing macros with arguments, and document
1292 behavior when the same variable has multiple AC_DEFINEs.
1293 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
1294 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
1295 macros directly, giving much shorter and simpler code.
1297 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
1299 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
1300 space before "$ac_configure_args" to prevent a 'config.status
1301 --recheck' failure if ac_configure_args doesn't contain a leading
1302 space. This works around a problem with the XEmacs configure.ac,
1303 which uses the (undocumented) ac_configure_args variable
1304 inconsistently with Autoconf.
1306 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
1308 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
1309 Include <limits.h>, and use its INT_MAX to rewrite the
1310 j loop so that it does not overflow 'int'. Problem reported by
1311 Ralf Wildenhues in
1312 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
1313 Play it safe by shifting left by 1 rather than multiplying by 2,
1314 as GCC is less likely to optimize this away when the value
1315 is signed (when it assumes overflow leads to undefined behavior).
1316 Also, don't assume time_t uses two's complement.
1318 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1320 * tests/torture.at (Substitute a 2000-byte string): Avoid using
1321 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
1322 dumps core on it. Report by Tim Rice.
1324 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1326 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
1327 --disable-option-checking to --help output even when
1328 AC_PRESERVE_HELP_ORDER is not used.
1329 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
1330 --with argument, rather than argument with [-.] replaced by
1331 underscores.
1332 * NEWS: Fix typo in previous change; the news was in the
1333 wrong section.
1335 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
1337 * NEWS: Warnings are now generated by default for unknown
1338 --enable-* and --with-* options.
1339 * doc/autoconf.texi (Option Checking): Renamed from
1340 (Configure Option Checking). Tighten up the wording a bit.
1341 (External Software, Package Options): Cross-reference to Option
1342 Checking, and use this to shorten our section.
1343 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
1344 "$x" to test "x$foo" != x.
1345 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
1346 Don't warn if $enable_option_checking is "no".
1347 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
1348 ac_unrecognized_opts to the empty string.
1349 Don't echo the unrecognized opts, as this might mishandle
1350 backslashes or leading -.
1351 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
1352 usage next to the other --disable-FEATURE options in the
1353 help string.
1355 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1357 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
1358 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
1359 Print warning for unrecognized --with and --enable options
1360 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
1361 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
1362 Disable option checking when subdirs are configured.
1363 (AC_OUTPUT): If warnings are enabled, print warning about
1364 unrecognized --with and --enable options at the end of
1365 the configure output (as well as at the beginning).
1366 * doc/autoconf.texi (Option Checking): New node.
1367 Document new option warning functionality.
1369 2006-12-16 Eric Blake <ebb9@byu.net>
1371 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
1372 * NEWS: Start news for current version.
1374 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
1376 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1377 Define HAVE_GETMNTENT to 1, not to the empty string.
1378 Problem originally reported by Jochen Friedrich in
1379 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
1381 This change prompted by a problem report by Andrey Simonenko in
1382 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
1383 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
1384 object-like macros only, in the traditional portable character
1385 set.
1386 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
1387 Warn about attempts to define things that are not identifiers.
1388 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
1389 awful hack that AC_DEFINEd macro names containing parentheses.
1391 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
1393 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
1394 too drastic, even if Texinfo in theory requires it for info mode.
1396 (config.status Invocation): Renamed back from Recreating a
1397 Configuration).
1398 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
1399 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
1401 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1403 * NEWS: Version 2.61a.
1405 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1406 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1408 * NEWS: Document changes with echo and printf, and the lack
1409 of limits on the total size of multi-line values of substituted
1410 variables, and the AC_FUNC_FSEEKO fix.
1412 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
1414 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
1415 Writing configure.ac.
1416 (Autoconf Input Layout): Renamed from configure.ac Layout.
1417 (Recreating a Configuration): Renamed from config.status Invocation.
1418 (Obsolete Recreation): Renamed from Obsolete config.status Use.
1419 (acconfig Header): Renamed from acconfig.h.
1420 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
1421 (Writing Testsuites): Renamed from Writing testsuite.at.
1422 (Autom4te Cache): Renamed from autom4te.cache.
1424 * BUGS: Remove mention of VPATH problem, since it's now documented
1425 not to be a bug in the Autoconf build procedure itself, but rather
1426 a problem with the proprietary `make' programs.
1428 * doc/autoconf.texi (Build Directories): Add a cross reference
1429 to VPATH and Make.
1431 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
1432 * doc/standards.texi: Sync from gnulib.
1434 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
1435 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
1436 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
1437 generated automatically.
1439 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
1441 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
1442 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
1443 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
1445 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1447 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
1448 `CEOF$ac_eof' special marker, the awk script cannot contain a
1449 line matching `^CEOF', so this is not needed any more.
1450 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
1451 special marker in the test.
1453 2006-12-06 Stepan Kasal <kasal@ucw.cz>
1455 * tests/tools.at (autom4te preselections): Use `find -newer';
1456 remove one of the sleeps.
1458 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
1459 more readable, using ...
1460 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
1462 * doc/autoconf.texi (autoheader Invocation): Do not double-
1463 quote the parameter of `AH_BOTTOM' in the example.
1465 2006-12-05 Stepan Kasal <kasal@ucw.cz>
1467 * doc/autoconf.texi (Configuration Headers): Remove the
1468 example with multiple input files.
1469 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
1470 multiple input files.
1472 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1474 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
1475 creating the awk substitution script, handle one input line at a
1476 time, so that the maximum length of a substituted (multi-line)
1477 value is not limited by the size of the sed pattern space.
1478 The trade-off is a slightly repetitive sed script.
1479 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
1480 can only have up to 7 characters, due to Solaris 10 /bin/sed.
1481 * tests/torture.at (Substitute a 2000-byte string): Increase the
1482 test with several long lines, they should not be caught by sed
1483 limits any more.
1485 * tests/tools.at (autom4te preselections): New test, to flag
1486 entries missing from autom4te.cfg.
1487 Report by David Byron <dbyron@hheld.com>.
1489 * tests/torture.at (Substitute a 2000-byte string): Actually use
1490 AC_PROG_AWK, so the last change works as intended.
1491 (Substitute and define special characters): Likewise.
1492 (Substitute a newline): Likewise.
1494 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
1495 instead of `awk' consistently.
1496 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
1497 * tests/torture.at (Torturing config.status): Test both the
1498 result of AC_PROG_AWK and plain awk.
1499 (Substitute a 2000-byte string): Likewise.
1500 (Substitute and define special characters): Likewise.
1501 (Substitute a newline): Likewise.
1503 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
1505 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
1506 can be assigned to a function pointer. Problem reported by
1507 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
1508 part of a patch by Ralf Wildenhues in that same bug report.
1510 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
1512 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
1513 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
1515 2006-12-01 Eric Blake <ebb9@byu.net>
1517 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
1518 cross-compiling from cygwin to mingw.
1519 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
1520 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
1521 to lib/autoconf/c.m4.
1523 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1525 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
1526 string for more reliable failure. Wrap the entire test that
1527 causes the broken Solaris printf to dump core, in a subshell,
1528 so the segmentation fault message is reliably suppressed.
1529 Fix shell expansion errors by using /usr/ucb/echo always;
1530 avoid an error on systems without it by another subshell.
1531 Avoid m4 expansion of `$1'. Set the zeroth argument of the
1532 subshell-$as_echo to `as_echo', for better error message.
1534 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1536 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
1537 `BASH_SOURCE' contain a newline, set them to empty, as they may
1538 not be unset.
1540 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
1542 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
1543 years and is too hard to maintain now. The last straw was
1544 reported by Jerker Baeck in
1545 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
1546 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
1547 * doc/autoconf.texi (Particular Functions): Move
1548 AC_FUNC_SETVBUF_REVERSED from here...
1549 (Obsolete Macros): ... to here. Say that it does nothing now.
1550 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
1551 Turn into (almost) a no-op.
1553 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
1554 (AC_C_VOLATILE):
1555 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
1556 These macros are obsolescent and new applications shouldn't need them.
1557 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
1558 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
1559 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
1560 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
1561 (AC_FUNC_VPRINTF): Likewise.
1562 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
1563 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
1564 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
1566 * doc/autoconf.texi (Setting Output Variables): Mention that
1567 @VAR1@VAR2 has unspecified behavior. Problem reported by
1568 Ralf Wildenhues.
1569 * NEWS: Mention this.
1571 * Makefile.am: Put only a single '#' into the copyright notice,
1572 so that it's also present in the output file. Standardize wording
1573 in makefile copyright notices to match GNU coding standards.
1574 * bin/Makefile.am: Likewise.
1575 * doc/Makefile.am: Likewise.
1576 * lib/Makefile.am: Likewise.
1577 * lib/freeze.mk: Likewise.
1578 * lib/autoconf/Makefile.am: Likewise.
1579 * lib/autoscan/Makefile.am: Likewise.
1580 * lib/autotest/Makefile.am: Likewise.
1581 * lib/m4sugar/Makefile.am: Likewise.
1582 * man/Makefile.am: Likewise.
1583 * tests/Makefile.am: Likewise.
1584 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
1585 one-line file.
1587 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1589 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
1590 in the sed script that mangles the awk script: delete up to the
1591 first exclamation mark only.
1592 * tests/torture.at (Substitute and define special characters):
1593 Test '!' too.
1595 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1597 Rewrite config files generation: avoid quadratic growth in
1598 the number of substituted variables by using awk instead of sed
1599 for the bulk of the substitutions.
1600 * NEWS: Mention this.
1601 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
1602 forbidden in the output (and thus input) file.
1603 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
1604 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
1605 generate just one large awk script for substitutions,
1606 eliminating much of the earlier complexity, while adding some
1607 new complexity. Only expand the substitution templates at
1608 configure time, for smaller configure script size. If
1609 _AC_SUBST_FILES are used, test 'awk' for working getline support
1610 at config.status time. If absent, interpolate through the
1611 shell. The awk script was written with much help
1612 from Paolo Bonzini and Paul Eggert.
1613 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
1614 (_AC_SED_FRAG_NUM): Likewise.
1615 (_AC_SUBST_CMDS): Renamed from...
1616 (_AC_SED_CMDS): ...this.
1617 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
1618 * tests/torture.at (Substitute a 2000-byte string): Also
1619 substitute a line with 1000 words, and a variable with several
1620 long lines.
1621 (Substitute and define special characters): Test awk special
1622 characters, and put substitution input strings `@foo@' in the
1623 output, to test that no recursion happens; test several other
1624 combinations from Paolo Bonzini.
1626 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
1628 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
1629 that replaced echo with AS_ECHO where this wasn't necessary.
1630 Problem reportd by Ralf Wildenhues.
1631 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
1632 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
1633 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
1635 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1637 * lib/freeze.mk (GREP): Removed, no need to initialize this.
1639 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
1641 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
1642 that traditional Awk lacks 3-arg "split". It has it.
1643 Mention that FS must be a single character, and a few other
1644 99-byte limits of traditional Awk.
1645 Mention that if (i in a) doesn't work with traditional Awk.
1647 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
1649 * tests/autotest.at (BSx641-newline in command):
1650 (BS-BS-newline in command, BSx640-newline in command):
1651 (Newline-CODE-BS-newline in command):
1652 (Single-quote-BS-newline in command):
1653 (Single-quote-newline-BS-newline in command):
1654 Use printf '%s\n' instead of echo, for portability to hosts
1655 where echo interprets backslashes. This will break on hosts
1656 that lack printf, but for now let's assume all such hosts
1657 are dead (if not, we should get reports of test failures).
1659 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
1661 'echo' has some portability problems, when given a first argument
1662 with a leading '-', or when given any argument containing '\'.
1663 Avoid using 'echo' in these cases.
1664 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
1665 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.

1688 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
1689 * bin/autoconf.as: Redo verbose flag implementation, as the old
1690 scheme wouldn't work with AS_ECHO.
1691 * lib/autotest/general.m4 (AT_INIT): Likewise.
1692 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
1693 Don't use ECHO_T, since ECHO_N is now reliable.
1694 * lib/autotest/general.m4 (AT_INIT): Likewise.
1695 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
1696 rather than using a here-document to put the script into a file.
1697 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
1698 use AS_ECHO.
1699 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
1700 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
1701 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
1702 bug, but we might as well stop using ECHO_N and ECHO_C internally.
1703 * lib/autotest/general.m4 (AT_SETUP): Likewise.

1705 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1706 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
1707 operand, as AS_ECHO requires. Avoid double file name expansion.
1708 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
1709 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
1710 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
1711 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
1712 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
1713 Double-quote strings that would otherwise contain M4 comments.
1714 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
1716 * configure.ac (AC_INIT): Bump to 2.61a.
1717 * NEWS: Likewise.
1719 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
1721 Version 2.61.
1723 * configure.ac (AC_INIT): Bump to 2.61.
1724 * NEWS: Likewise.
1726 * tests/autotest.at (Macro with backslash in a test title):
1727 Comment out for now, as this tests neither fails nor passes
1728 reliably. Problem reported by Ralf Wildenhues.
1730 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
1732 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
1733 in previous change, which caused test failures.
1735 2006-11-16 Stepan Kasal <kasal@ucw.cz>
1737 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
1738 code for --enable, --disable, --with, and --without to...
1739 (_AC_INIT_PARSE_ENABLE): ... a new macro.
1740 * doc/autoconf.texi (Package Options):

1743 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
1745 Import these changes from config via gnulib:
1747 2006-11-15 Ben Elliston <bje@gnu.org>
1749 From Josselin Mouette <joss@debian.org>:

1804 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
1806 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
1807 benefit of platforms like Solaris+GCC where it is common to have a
1808 non-working g++ installation.
1810 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1811 and Joel E. Denny <jdenny@ces.clemson.edu>
1812 and Paul Eggert <eggert@cs.ucla.edu>
1814 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
1815 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
1816 ./micro-suite.
1818 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
1820 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
1821 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
1822 Imported from a similar patch to gnulib by Bruno Haible.
1824 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
1826 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

1834 Tandem NonStop Kernel (OSS) cc -O circa 2004, reported by
1835 Matthew Woehlke.
1837 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1839 * tests/torture.at (Configuring subdirectories): Do not skip
1840 Automake 1.10 nor future Automake 11.1 (sic).
1842 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
1843 and Stepan Kasal <kasal@ucw.cz>
1845 Handle special characters in test case titles correctly.
1846 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
1847 properly.
1848 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
1849 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
1850 argument. Extend to check titles printed by ./micro-suite and
1851 ./micro-suite -l and the title in micro-suite.log.
1852 (Backquote in a test title,
1853 Single-quote in a test title,
1854 Double-quote in a test title): Don't expect failure anymore.
1855 (Backslash in a test title): Put a non-whitespace character after the
1856 backslash so that Bourne shells might actually see it as an escape
1857 sequence.
1858 (Brackets in a test title,
1859 Pound in a test title,
1860 Comma in a test title,
1861 Quoted Macro in a test title,

1867 * tests/torture.at (#define header templates): M4-quote this title in
1868 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
1869 The visible effect was a stray [] in the testsuite output.
1871 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1873 * doc/autoconf.texi (Limitations of Builtins): Do not invoke

1876 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
1878 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
1879 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
1880 5363) simply issues a warning when dividing by zero at compile
1881 time. Problem reported by Elias Pipping.
1883 2006-10-26 Eric Blake <ebb9@byu.net>
1885 * THANKS: Update.
1886 * doc/autoconf.texi (Evaluation Macros): Improve the example to
1887 show effect on macros that expand with commas.
1888 Reported by Joel E. Denny.
1890 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
1891 Also work with M4 1.4.8.

1915 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
1916 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
1917 reported by Nelson H. F. Beebe for Coreutils 6.4.
1919 * tests/tools.at (autoconf --trace: user macros): Remove test
1920 for tracing multiline macros, since m4 1.4.7a uses a different
1921 way to number lines. Problem reported by Ralf Wildenhues.
1923 2006-10-24 Stepan Kasal <kasal@ucw.cz>
1925 * bin/autom4te.in (handle_m4): Do not redirect stdin to
1926 /dev/null since the heuristics for interactive behaviour was
1927 fixed in CVS m4.
1929 * bin/autom4te.in: With --force, always refresh the output
1930 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

1949 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
1950 AC_CACHE_CHECK_INT, since it's no longer public.
1951 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
1952 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
1954 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1956 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
1958 2006-10-19 Eric Blake <ebb9@byu.net>

1980 2006-10-14 Stepan Kasal <kasal@ucw.cz>
1982 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
1983 looking for special shell characters.
1984 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
1985 macro defined by AS_VAR_PUSHDEF before passing it as a
1986 parameter.
1987 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
1988 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

1997 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1999 (Imported from Automake.)
2000 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
2001 which incorrectly sets the mode of an existing destination
2002 directory. In some cases the unpatched install-sh could do the
2003 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
2004 system. We hope this is rare in practice, but it's clearly worth
2005 fixing. Problem reported by Alex Unleashed in
2006 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
2007 Also, don't bother to check for -m bugs unless we're using -m;
2008 suggested by Stepan Kasal.
2010 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
2012 Import this change from Automake:
2014 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>

2016 is enabled by default with gnu and gnits strictness.
2017 Report from Bruno Haible.
2019 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
2020 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
2021 gnu and gnits modes.
2023 Import this change from Config:
2025 2006-09-20 Ben Elliston <bje@gnu.org>
2026 * build-aux/config.sub (score, score-*): New.
2028 Import this change from Gnulib:
2030 2006-09-16 Karl Berry <karl@gnu.org>
2031 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
2032 to avoid sectioning errors.
2034 Import these changes from Texinfo:
2036 2006-10-04 Karl Berry <karl@gnu.org>
2037 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
2038 (\quoteexpand): rename to \rquoteexpand.
2039 (\codequoteleft): new def, to look for @set codequotebacktick.
2040 (\lquoteexpand, \quoteexpand): new defs.
2041 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
2042 (\code): must use new \...Char values, since now ` is active.
2044 2006-08-26 Karl Berry <karl@gnu.org>
2045 * build-aux/texinfo.tex (\textdegree): New command.
2047 2006-08-12 Karl Berry <karl@gnu.org>
2048 * build-aux/texinfo.tex (error \box0): smaller font.

2052 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
2054 2006-10-13 Stepan Kasal <kasal@ucw.cz>
2056 * doc/autoconf.texi (Autoheader Macros): Warn that the text
2057 added to the template can get mangled.
2059 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2061 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
2062 include the default headers, and redefine obstack_chunk_alloc
2063 and obstack_chunk_free. Fixes false failure with glibc.
2065 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
2067 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
2068 for backward compatibility with Libtool 1.5.22. Problem reported
2069 by Ralf Wildenhues.
2071 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2073 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
2074 AC_PROG_CC.
2075 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
2077 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
2079 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
2080 the NonStop platform.
2081 * doc/autoconf.texi (Posix Variants): Likewise.
2082 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
2084 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
2085 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
2086 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
2087 Use a better substitute, by inspecting the output of "ls"
2088 rather than just using ":".
2089 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
2090 rather than AS_EXECUTABLE_P, since we needn't worry about
2091 non-regular files here.
2093 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
2094 due to configuration hassles with this. See Tonya Underwood's report
2095 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
2096 * doc/autoconf.texi (Special Shell Variables): Likewise.
2098 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
2099 Stepan Kasal <kasal@ucw.cz>

2102 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
2104 2006-10-11 Stepan Kasal <kasal@ucw.cz>
2106 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
2107 initialization which is not inherited through the environment
2108 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
2109 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
2111 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
2113 * doc/autoconf.texi (Limitations of Usual Tools): Describe
2114 problems with mkdir -p -m.
2116 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
2118 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
2119 comment about ac_cpp_err; it was incorrect, and anyway
2120 ac_cpp_err is being removed below.
2121 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
2122 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
2123 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
2124 nobody uses it.
2125 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
2126 with werror_flag and conftest.err and so forth. This is more
2127 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
2128 and anyway the user shouldn't normally want to see this gorp logged.
2129 Problem reported by Ralf Wildenhues.
2130 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
2131 empty, not 'no', since the rest of the code uses 'test -z'.
2133 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
2135 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2136 Use a single call to AC_DO_TOKENS rather than multiple, for
2137 efficiency.
2138 (_AC_LINK_IFELSE): Test that resulting file is executable.
2139 Problem reported by mwoehlke in
2140 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
2142 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
2143 than creating a file to use with test -x; this is much faster.
2145 2006-10-02 Bruno Haible <bruno@clisp.org>
2147 * lib/autom4te.in (Automake-preselections): Add
2148 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
2150 2006-09-27 Stepan Kasal <kasal@ucw.cz>
2152 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
2153 standard error, `experr' should be used, not `expout'.
2155 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
2157 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
2158 fseeko testing program twice; just use the earlier result.
2159 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2160 Set cache var to 'unknown' (not 'no') if leaving the macro unset
2161 still doesn't let the program compile.
2162 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
2163 failed.
2165 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
2166 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
2167 include it, without including anything else.
2168 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
2169 expressions.
2170 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
2172 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2174 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
2175 `error.h', and include it, for a `error_at_line' prototype.
2176 Use a nonempty format string in the link test.
2177 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
2178 for a declaration of wait3.
2180 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
2182 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
2183 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
2184 can apply to constants too, and that it checks for macro defns.
2185 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
2186 and simply cast the identifier to void. This handles structure
2187 values. Problem reported by Ralf Wildenhues.
2188 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
2190 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2192 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
2193 structure, and function symbols.
2195 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2197 * tests/semantics.at (AC_CHECK_MEMBERS): Also test with a struct
2198 member.

2210 warnings (uninitialized value).
2211 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
2212 present.
2213 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add

2243 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
2244 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
2245 --error-output, to avoid warnings with M4 2.0.
2247 2006-09-19 Stepan Kasal <kasal@ucw.cz>
2249 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be

2260 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
2261 mistaken comment: the path has to be relative; do not use
2262 the path at runtime.
2264 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2266 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

2270 for both changes.
2271 * doc/autoconf.texi (Setting Output Variables): Fix example to
2272 not show `--silent' being passed to a `configure' re-run.
2274 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
2276 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
2277 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
2278 for the existence of the directory at configure-time. That's
2279 too late, anyway. Problem reported by Stefan Seefeld.
2281 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
2282 7.1.4 /usr/bin/posix/sh described by Tim Rice in
2283 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
2285 2006-09-11 Stepan Kasal <kasal@ucw.cz>
2287 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
2288 works with GNU M4 1.4.3 again; make the normalized form
2289 match the current m4 message; fix the description.
2290 * test/tools.at (autom4te cache): Adapt to the change.
2292 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
2294 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
2295 to catch glibc bug 2821
2296 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
2298 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
2299 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
2300 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
2301 assume C89.
2303 2006-09-08 Stepan Kasal <kasal@ucw.cz>
2305 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the

2323 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
2324 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
2325 accept files with extension `.f'. For consistency, also prefer
2326 xlf over f77.
2327 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
2328 from last patch.

2345 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
2347 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
2348 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
2349 except the first two arguments are reversed.
2350 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
2351 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer

2360 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
2362 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
2363 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
2364 programs should use their Gnulib counterparts.
2365 * doc/autoconf.texi (Particular Functions): Likewise.
2366 (Macro Names, testsuite Invocation): Replace uses of these
2367 obsolete macros with uses of non-obsolete macros.

2396 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
2397 for the default, which the user can override.
2398 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
2399 deal with LEXLIB.
2400 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
2401 didn't work if some values were cached but not others. Test for
2402 broken lex libraries like native ia64-hp-hpux11.22; see
2403 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
2404 work around the problem by preferring an empty LEXLIB to -lfl or
2405 -ll. Let the user set LEXLIB='' to indicate no library needed.
2407 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
2408 * README: Likewise.
2409 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

2510 * doc/autoconf.texi (Particular Programs): Mention that
2511 @INSTALL@ and @MKDIR_P@ may vary for different output files.
2512 Reported by Alexandre Duret-Lutz.
2514 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
2516 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore

2534 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
2535 * doc/autoconf.texi (Header Templates, Default Includes):

2550 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
2551 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
2552 this.

2556 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
2557 problems with arg script text that doesn't end in newline, and

2560 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
2562 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

2572 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
2573 --help' should mention that `--version' outputs configuration
2574 settings. Report by Bruno Haible.
2576 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
2578 Fix test suite failures reported by Pierre in

2594 less skeptical about "volatile", after discussion with
2595 Bruno Haible on bug-gnulib.
2596 (Limitations of Usual Tools): Warn about sed stripping
2597 leading white space from text. From Bruno Haible.
2599 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
2601 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
2602 compiler complains about it, even if things works after the
2603 complaint. Problem reported by Peter O'Gorman.
2605 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
2606 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
2607 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
2609 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
2611 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

2619 to match M4 1.4.5.
2621 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
2623 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
2624 under AC_C_VOLATILE.
2625 (Volatile Objects): Be a little less skeptical about what
2626 "volatile" means. Derived from thoughts by Ben Pfaff in
2627 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
2629 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2631 * doc/autoconf.texi: Fix some typos.
2633 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
2635 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2636 more globally, since the 2006-06-30 patch didn't suffice. Problem
2637 reported by Keith Marshall. Also, don't bother with builddir2,
2638 since it shouldn't be needed any more.
2640 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
2642 * doc/autoconf.texi (Generic compiler characteristics):
2643 Document AC_COMPUTE_INT. Fix wrong statements on Default

2657 * NEWS: Document previous change.
2659 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
2661 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
2662 Require that long long int be at least 64 bits wide. C99 requires
2663 this and enough programs depend on it so we should check for it.
2664 Bruno Haible reports in
2665 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
2666 that long long int is 32 bits wide with some nonstandard compilers.
2667 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
2669 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
2671 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2672 to a nonexistent file, so that we don't have to worry about
2673 a local site configuration that doesn't use /usr/local.
2674 Problem reported by Keith Marshall in
2675 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
2677 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
2679 * doc/autoconf.texi: Be more consistent about using @acronym with
2680 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
2681 quite right (it talked about "OSF/Tru64", even though the
2682 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
2683 and it even mentioned "OSF 4"!) and at this point there's little
2684 reason to talk about OSF any more, since it died in 1994.
2685 (Specific Compiler Characteristics): Simplify example of
2686 negative-size array.
2687 (File Descriptors): Reorder to make the text flow better.
2688 Remove joke about "appreciate the various levels"; I didn't get it.
2689 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
2690 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
2691 (File Descriptors, Limitations of Usual Tools):
2692 Tone down the advice against renaming or removing open files.
2693 (Limitations of Usual Tools): Add a new section, on 'rm'.
2695 2006-06-26 Stepan Kasal <kasal@ucw.cz>
2697 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
2698 -lXt in LIBS, idea from Karsten Hopp; this was due since
2699 this change:
2701 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2702 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2703 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2704 (which belong to Xt, not X itself). See Debian bug 327655.
2706 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2708 * configure.ac (AC_INIT): Bump to 2.60a.

2725 Fix typos.
2727 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
2728 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
2729 not defined.
2730 * doc/autoconf.texi (Changed Directory Variables): New node,
2731 to document the whole `datarootdir' business a bit better.
2732 * NEWS: Update.
2733 * tests/torture.at (datarootdir workaround): Extend test.
2734 Prompted by report by Alexandre Julliard.
2736 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
2738 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility

2740 fix reported by Larry Jones.
2742 2006-06-22 Alexandre Julliard <julliard@winehq.org>
2744 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
2745 about literal '${datarootdir}' if a definition is found in the
2746 output file.
2748 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
2750 * NEWS: Use "M4" rather than "m4" when appropriate.
2751 Problem reported by Eric Blake.
2752 * doc/autoconf.texi: Likewise.
2753 Use @acronym around BSD, GCC, and GNU when appropriate.
2754 (Why GNU M4): Renamed from "Why GNU m4".
2755 (Redefined M4 Macros): Mention that Posix
2756 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
2757 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
2758 to int.
2760 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2762 * bin/autom4te.in (handle_output): Do not forbid the empty
2763 pattern.
2764 * tests/tools.at (autoconf: the empty token): New test.
2766 2006-06-20 Stepan Kasal <kasal@ucw.cz>
2768 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
2769 calls, so that we do not care whether they are LIFO or FIFO;
2770 in the m4_wrap, do not check which diversion is the topmost
2771 one, just check that the stack is balanced at the end.
2772 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
2773 base diversion forever--pop the previous diversion before
2774 opening the new one; consequently, remove the m4_wrap call.
2775 * lib/autotest/general.m4 (AT_INIT): Likewise.
2776 * tests/m4sugar.at: Do not use
2777 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
2779 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
2780 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2782 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
2783 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
2784 Rework example of m4wrap token-pasting trouble so that it doesn't
2785 care whether it's LIFO or FIFO.
2786 Fix some "contrary to"s that are awkward in English.
2788 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2790 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
2791 to `yes' instead of `int$1_t' if the type is found, for more
2792 consistent configure output (where $1 is the number of bits).
2793 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
2794 Suggested by Bruno Haible.
2796 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
2797 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
2798 with system headers. Report by Bruno Haible.
2800 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2802 * config/config.guess, config/config.sub: Sync from upstream.
2804 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
2805 in order to avoid picking up an older installed frozen m4sh.m4f.
2806 Besides an outdated shell startup, this could have been created
2807 by an earlier M4 version with incompatible frozen file format.
2809 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
2811 * README: Recommend m4 1.4.4 instead of 1.4.3..
2812 * doc/autoconf.texi: Likewise.
2813 (Special Chars in Names): Say that $(.FOO) is portable, as
2814 suggested by Stepan Kasal.
2815 (Installation Directory Variables, Build Directories):
2816 (Automatic Remaking, Subdirectories, Fortran Compiler):
2817 (Making testsuite Scripts, Defining Directories):
2818 Quote variable usages better.
2819 (Making testsuite Scripts): Add clean-local rule to makefile
2820 snippet, by Eric Blake.
2821 (Installation Directory Variables): Fix table item font.
2822 Reword slightly to clarify. Generalize advice about
2823 not using special characters to include all file-related
2824 vars, not just VPATH.
2825 (Special Chars in Variables): Warn about special characters in
2826 $(srcdir) too.
2827 (Assignments): Clarify default-value example as suggested by
2828 Ralf Wildenhues in
2829 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
2830 (Special Shell Variables): Note leading ./ or ../, as suggested
2831 by Eric Blake.
2832 (Limitations of Builtins): Under cd, warn about CDPATH.
2833 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
2834 Ralf Wildenhues.
2836 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2838 * doc/autoconf.texi (Configuration Actions): Remove duplicate
2839 `@var', for texi2html.
2840 (Systemology): Some more word wrapping, for DVI output.
2841 (autom4te Invocation): The short option for `--melt' is `-M',
2842 not `-m'.
2844 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
2846 * doc/autoconf.texi: More formatting and English tweaks,
2847 many suggested by Ralf Wildenhues.
2848 Reword to avoid "@code{...}'s" and the like, since it's ugly
2849 with Emacs info mode. discontents -> woes.
2850 Put a few "will"s back. time stamp -> timestamp.
2851 side-effect -> side effect.
2853 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
2855 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
2856 Warn about $@ not persisting. Problem reported by Julien Danjou in
2857 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
2858 (Special Chars in Names): Renamed from Leading _ in Macro Names.
2859 Mention other special chars, too.
2861 2006-06-14 Eric Blake <ebb9@byu.net>
2863 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
2865 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
2867 * doc/autoconf.texi: Some systematic minor improvements, as
2868 follows. Use "makefile" when talking about makefiles
2869 generally (which might be named "makefile" or "Makefile" or even
2870 "foo.mk"), "Makefile" when talking about a specific makefile
2871 called "Makefile". This unclutters the text from weird quotes
2872 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
2873 values" rather than "@var{foo}s" and similar constructs containing
2874 "}s". Use "Make rules" rather than "Makefile rules". Minor
2875 English-language improvements. Change the prefix "sub-" to "sub"
2876 and "re-" to "re".
2877 Put blank lines around examples more consistently.
2878 Avoid "rather" and "very" as intensifiers.
2879 Avoid "will" as an auxiliary.
2880 (Limitations of Make): Split this node into....
2881 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
2882 (Leading _ in Macro Names, Backslash-Newline-Newline):
2883 (Backslash-Newline Comments, Long Lines in Makefiles):
2884 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
2885 (obj/ and Make, make -k Status, VPATH and Make):
2886 (VPATH and Double-colon, $< in Explicit Rules):
2887 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
2888 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
2889 New nodes, resulting from splitup of Limitations of Make.
2890 All cross-references changed. Raise the top node from
2891 a section to a chapter, and all subnodes accordingly.
2892 Redo the introductory wording to match the new organization.
2893 (Installation Directory Variables): Use an example that is
2894 closer to what Autoconf actually does. Mention that VPATH's
2895 value should not contain metacharacters or white space.
2896 (Fortran Compiler): Fix a VPATH bug in an example.
2897 (Leading _ in Macro Names): Mention that this problem is no longer
2898 of practical concern.
2899 (VPATH and Make): Reword the advice to make it clearer
2900 that Autoconf and Automake support VPATH in non-GNU make, but
2901 many packages have bugs in this area.
2902 ($< in Explicit Rules): Refer to Build Directories rather
2903 than using a (non-VPATH-safe) example.
2904 (Automatic Rule Rewriting): Mention the sort of disaster that
2905 can ensue with Solaris-style rule rewriting with VPATH.
2907 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2909 * doc/install.texi (Compilers and Options): Weaken the
2910 suggestion to use GNU make for VPATH builds.
2912 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
2913 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
2915 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
2916 in regular expression.
2918 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2920 * doc/autoconf.texi (Installation Directory Variables):
2921 Drop extra @samp from `@table @samp' item.
2922 (Limitations of Usual Tools): Comment fix.
2923 Do not nest @samp just to point to other table items.
2924 (Writing testsuite.at) <AT_CHECK>: The second argument to
2925 `@dvar' is already @samp'ed.
2926 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
2927 do not use @var in the second argument.
2929 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
2931 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
2932 $as_shell.exe too. Problem reported by Andreas Buening in
2933 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
2935 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2937 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
2938 `unused variable' compiler warning, for `-Wall -Werror'.
2939 Reported by Jaap Haitsma in
2940 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
2942 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
2944 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
2945 case the compiler dumps core. Problem reported for
2946 OpenServer 5.0.7 by Tim Rice in
2947 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
2948 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2949 Likewise.
2951 2006-06-06 Tim Rice <tim@multitalents.net>.
2953 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
2954 "ERROR" only shows up in "make check" output if there is an
2955 error.
2957 2006-06-06 Eric Blake <ebb9@byu.net>
2959 * tests/tools.at (automatically allowed tokens): Fix typo.
2961 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2963 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
2965 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
2966 typically overflows on x86 CPUs, even though the C standard
2967 requires otherwise.
2969 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2971 * configure.ac (AC_INIT): Bump to 2.59e.
2972 * NEWS: Update.
2974 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2976 Version 2.59d.
2978 * config/texinfo.tex: Sync from upstream.
2980 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
2981 seen, invoke libtoolize with `--ltdl' argument.
2982 * lib/autom4te.in (Autoreconf-preselections): Adjust.
2983 * NEWS: Update.
2984 Suggested by Eric Blake.
2986 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2988 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
2989 reported by Ralf Wildenhues.
2990 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
2992 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2994 * THANKS: Update.
2996 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2998 * doc/autoconf.texi: Modernize some of the references to Solaris.
3000 2006-06-05 Stepan Kasal <kasal@ucw.cz>
3002 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
3003 message issued by AC_REQUIRE.
3004 * tests/m4sugar.at: Check m4_require's error message.
3005 * tests/base.at: Check AC_REQUIRE's error message.
3006 * tests/local.at (AT_CHECK_M4): New macro, almost identical
3007 to...
3008 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
3009 AT_CHECK_M4.
3010 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
3011 `expout' as the last parameter.
3012 * tests/tools.at: Adapt to the above change.
3014 2006-06-04 Stepan Kasal <kasal@ucw.cz>
3016 * doc/autoconf.texi (Limitations of Usual Tools): Correct
3017 information about race-free implementations of mkdir.
3019 2006-06-04 Eric Blake <ebb9@byu.net>
3021 * bin/autoreconf.in (help): Document M4 environment variable.
3022 * bin/autoconf.as (Usage): Likewise.
3023 * bin/autom4te.in (help): Likewise.
3024 * doc/autoconf.texi (autom4te Invocation): Likewise.
3026 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
3028 * NEWS: GNU make now recommended for VPATH builds.
3029 Mention that some macros are now documented to be obsolescent.
3030 * doc/autoconf.texi:
3031 Prefer "current" to "modern" to describe
3032 currently-used (albeit perhaps old-fashioned) hosts.
3033 Mention which ancient features no longer need to be worried about.
3034 setgid -> set-group-ID
3035 setuid -> set-user-ID (these are the Posix terms)
3036 Fix some misuses of "only".
3037 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
3038 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
3039 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
3040 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
3041 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
3042 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
3043 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
3044 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
3045 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
3046 Mention that these macros are obsolescent.
3047 (Installation Directory Variables): shall -> should
3048 (File Descriptors): Mention that 0, 1, 2 might get reopened.
3049 Mention that it's now safe to use 3 and 4.
3050 (Limitations of Usual Tools): cp -r is now specified by Posix.
3051 Omit longwinded and obsolescent discussion of cp -f.
3052 Modernize discussion of expr, ls.
3053 (Limitations of Make): Modernize discussion of VPATH builds.
3054 Mention $? as a workaround in some cases.
3055 * doc/install.texi (Basic Installation):
3056 Mention "./configure; make; make install" first. Be more
3057 specific about why this file is generic. Remove unnecessary
3058 parens. Remove misleading "only". Remove obsolete advice
3059 about csh. Don't say "configure" takes awhile; say it
3060 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
3061 and CC=c99 rather than CC=c89, as these are blessed by current
3062 Posix. Recommend GNU make if doing a VPATH build.
3064 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
3066 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
3067 examples involving shell prompts.
3069 2006-06-02 Stepan Kasal <kasal@ucw.cz>
3070 and Paul Eggert <eggert@cs.ucla.edu>
3072 * doc/autoconf.texi (Here-Documents): Add details about the
3073 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
3074 use "here-documents" instead of "here documents".
3076 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3078 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
3080 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
3082 * doc/autoconf.texi (File System Conventions): Warn about ":"
3083 anywhere in directory names.
3085 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
3087 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
3088 about quoting the case statement, just in case.
3089 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
3090 was fixed in ksh93g; reported by Ralf Wildenhues.
3092 2006-05-31 Stepan Kasal <kasal@ucw.cz>
3094 * doc/autoconf.texi (System Services): Do not document
3095 overriding EXEEXT via ac_cv_exeext=ext.
3096 (Particular Programs) <AC_PROG_MKDIR_P>:
3097 Document that ${MKDIR_P} understands --.
3098 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
3099 comment.
3101 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3103 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
3104 argument with leading hyphen. Problem reported by Paul Eggert.
3106 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3108 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
3109 about quoting ac_try: quote all of it, if any of it seems suspicious.
3110 This means we don't have to worry about ${ or sed any more.
3111 Also, double-quote the case statement, to work around misuses via
3112 underquoting as reported by Ralf Wildenhues in
3113 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
3114 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
3115 undocumented and dangerous macro.
3116 Problem reported by Ralf Wildenhues in
3117 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
3119 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3121 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
3122 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
3123 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
3125 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3127 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
3128 since evidently some packages rely on the old, broken behavior.
3129 Problem reported by Ralf Wildenhues in
3130 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
3131 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
3132 pre-2006-05-26 definitions, but leave in the comments that
3133 these macros are dangerous and should not be used.
3134 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
3135 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
3136 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
3137 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
3138 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
3140 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
3142 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
3143 the use of 'tr', since this is our only use of 'tr'.
3145 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3146 and Paul Eggert <eggert@cs.ucla.edu>
3148 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
3149 Don't assume 'grep' works on long lines, since AIX grep doesn't.
3151 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3153 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
3154 the output file in the `${datarootdir}' test.
3156 2005-05-28 Stepan Kasal <kasal@ucw.cz>
3157 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3159 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
3160 mention of `datarootdir' in the input file(s), but literal
3161 `${datarootdir}' in the output file, and we haven't warned yet,
3162 then warn as well: the user may have (erroneously) used
3163 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
3164 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
3165 * tests/torture.at (datarootdir workaround): Extend this test.
3166 * NEWS: Update.
3168 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3169 and Paul Eggert <eggert@cs.ucla.edu>
3171 * doc/autoconf.texi (autoheader Invocation): The first argument to
3172 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
3173 alternatives and clear up the language a bit.
3175 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
3177 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
3178 ac_config_guess, ac_config_sub, ac_configure.
3179 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3180 Fix typo that prevented an unnecessary space from being removed.
3181 Problems reported by Ralf Wildenhues in:
3182 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
3184 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
3186 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
3187 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
3188 Don't use the term "thread-safe" to talk about mkdir race
3189 conditions, since the problem is more a process than a thread
3190 issue. Problem reported by Stepan Kasal in:
3191 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
3192 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
3193 the test for 'install' more closely. Look at MKDIR_P first.
3194 Look in the PATH, and at /opt/sfw/bin.
3195 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
3196 Don't bother to try mkdir -p, since we already check mkdir --version;
3197 just look at the version number. (There's no easy way to check
3198 for race-free implementations.)
3199 * tests/tools.at (autoconf: subdirectories): Adjust to above
3200 changes, since MKDIR_P now might end in "/mkdir -p".
3202 * doc/autoconf.texi (autoheader Invocation): Mention that the
3203 first arg of AC_DEFINE_UNQUOTED must be a literal.
3204 Problem reported by Ben Pfaff in
3205 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
3207 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
3208 * doc/autoconf.texi (Special Chars in Variables): New section.
3209 (Preset Output Variables): Warn about special chars in CPPFLAGS.
3210 (Installation Directory Variables): Quote $(datadir) better.
3211 (Limitations of Builtins): Describe some of eval's trickiness.
3213 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
3214 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
3215 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
3216 in front of every arg, not just trailing args. Quote apostrophes.
3217 (_AC_EVAL_ECHO): New macro.
3218 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
3219 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
3220 removed.
3221 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
3222 exposed by quoting of eval argument. Put the command on line line
3223 so it logs better.
3224 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
3225 (_AC_PATH_X, AC_PATH_X): Quote more safely.
3226 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
3227 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
3228 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
3229 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
3230 Use eval more safely.
3231 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
3232 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
3233 to be replaced.
3234 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
3235 lines, exposed by quoting of eval argument.
3237 2006-05-26 Stepan Kasal <kasal@ucw.cz>
3238 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3240 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
3241 initialization of `ac_cv_exeext', do not override it if it was
3242 already set, unless it was set to `no', for compatibility with
3243 Autoconf-2.13, and comment this.
3244 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
3245 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
3246 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
3247 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
3248 Document that this test may be overridden by setting
3249 `ac_cv_exeext'.
3251 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3253 Revert these two patches:
3255 2006-04-06 Eric Blake <ebb9@byu.net>
3256 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3257 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3258 2006-04-01.
3260 2006-04-01 Stepan Kasal <kasal@ucw.cz>
3261 Clean up _AC_COMPILER_EXEEXT* macros.
3262 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3263 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3264 ac_file to the name of the default output file and call
3265 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3266 initial `rm' of the candidate files...
3267 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3268 the same list in subsequent `rm' calls, and for the temporary
3269 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3270 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3271 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3272 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3273 no longer needed) by libtool. Make it a cache check.
3274 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3275 copied here by mistake.
3276 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3277 _AC_COMPILER_EXEEXT.
3278 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
3279 _AC_COMPILER_OBJEXT directly.
3280 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3282 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3284 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
3285 Fix description of how the buggy `sed' works.
3287 2006-05-25 Noah Misch <noah@cs.caltech.edu>
3289 Sync from Automake:
3291 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
3292 ENOLCK. Only mention `make -j' when applicable. Only raise
3293 fatal errors when `make -j' is involved. Improve error message.
3295 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3297 * doc/autoconf.texi (Here-Documents): We now know more about
3298 the variable expansion in here documents bug.
3299 Thanks to Tim Rice and Stepan Kasal.
3301 * doc/autoconf.texi (Making testsuite Scripts): Add an example
3302 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
3304 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3306 * tests/autotest.at (Multiline command from M4 expansion):
3307 No failure to be expected if the shell quotes newlines in
3308 commands in the `set -x' output. Report by Tim Rice.
3309 * THANKS: Update.
3311 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3313 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
3314 expansion in the here-documents used by config.status, as that
3315 runs afoul of the Korn shell version M-12/28/93d bug described in
3316 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
3317 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
3318 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
3320 2006-05-23 Jim Meyering <jim@meyering.net>
3322 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
3323 Fix typo introduced with 2006-04-02 change. It reversed the sense
3324 of the test.
3326 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3328 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
3329 ac_dB slightly, to save bytes in the script.
3330 Max out at 50 lines, rather than 96; this is more likely
3331 (though not guaranteed) to avoid obscure 'sed' failures.
3333 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3335 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
3336 `tr -d -' as bad option argument. Work around this by deleting
3337 an unrelated character.
3338 Report by Tim Rice <tim@multitalents.net>.
3340 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
3341 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3342 Stepan Kasal <kasal@ucw.cz>
3344 * doc/autoconf.texi (Particular Programs): Do not promise that
3345 we always prefer the GNU version of the program, and that we
3346 search according to PATH; both rules can have exceptions.
3347 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
3348 AC_PROG_SED. Move descriptions of limitations
3349 to the Limitations of Usual Tools section.
3350 (Limitations of Usual Tools) <sed>: Mention script length
3351 limitations with Solaris /usr/ucb/sed.
3352 <grep>: Fix wording for empty alternative. Mention that -c and
3353 -l should not be combined, and that -E and -F should not be
3354 combined.
3356 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3357 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3359 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
3360 limits in Solaris 8 /usr/ucb/sed by testing a long script.
3362 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3364 * doc/autoconf.texi (Defining Symbols): Literal parameter of
3365 AC_DEFINE is now passed to m4_pattern_allow.
3366 * NEWS: Mention that; likewise for AC_SUBST.
3367 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
3368 the parameter to m4_pattern_allow.
3369 * tests/tools.at: Add a check for that.
3371 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3373 * lib/autoconf/status.m4: Fix typos.
3375 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3377 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
3378 only the files that this macro generates.
3380 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3382 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
3383 the HP-UX sed limitation of 99 commands, labels do not count.
3384 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
3385 in the comment.
3386 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
3388 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3390 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3391 Import the following fix from coreutils:
3393 2006-01-13 Jim Meyering <jim@meyering.net>
3395 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
3396 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
3397 not double-quote uses of that variable, to accommodate the rare
3398 case in which getmntent is available in none of the libraries
3399 checked. This happens at least on FreeBSD 5.0.
3401 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
3403 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
3404 ac_config_guess, ac_config_sub, and ac_configure, since evidently
3405 some other programs unwisely rely on these undocumented vars.
3406 But put in warning comments about them.
3407 Problem reported by Ralf Wildenhues in
3408 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
3409 * NEWS: Document that these variables are intended to go away.
3411 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3413 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
3414 and set the language to C++ (analogous to the equivalent Fortran
3415 tests).
3417 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
3418 * doc/autoconf.texi (C++ Compiler): Document it.
3419 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
3420 * NEWS: Update.
3422 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
3424 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
3425 that caused config.status to generate 100-command sed scripts; the
3426 portable limit is 99.
3428 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3430 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
3431 variable `ac_d' instead of `d' to avoid infringing namespace.
3432 Report by Ralf Menzel.
3434 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
3436 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
3437 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
3438 * tests/tools.at (autoconf: subdirectories): New test, taken from
3439 the corresponding problem report by Ralf Wildenhues in:
3440 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
3442 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
3443 Quote some uses of shell variables if they might suffer unexpected
3444 globbing. This doesn't fix all instances of quoting problems that
3445 I found, just the easy ones that look safe.
3446 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
3447 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
3448 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
3449 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
3450 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
3451 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
3452 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
3453 Likewise.
3454 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
3455 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
3457 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3459 * bin/autoreconf.in ($help): Reword according to the manual.
3460 Suggested by Olly Betts.
3462 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
3463 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3465 * bin/autoreconf.in: Pass the directory argument to
3466 `require_configure_ac'. Fix comment.
3467 * tests/torture.at (Configuring subdirectories): Expose this.
3468 Reported by Olly Betts.
3470 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3472 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
3473 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
3474 Automake as follows:
3476 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
3477 `$configure_in' instead of `configure.in', to preserve
3478 directory component.
3480 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3482 * config/config.guess, config/config.sub, config/texinfo.tex,
3483 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
3485 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
3487 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
3488 test for C99 conformance; (bool) 0.5 is an integer constant
3489 expression, but (bool) -0.5 is not. Problem reported by Fedor
3490 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
3492 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
3494 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
3495 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
3496 Warn about obsolete install-sh files. Remove stray sentence
3497 fragment and fix cross reference.
3498 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
3499 install -d; this undoes the 2006-05-10 change.
3500 (MKDIR_P): Mark with AN_MAKEVAR.
3501 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
3502 that we don't require $INSTALL to be thread-safe. Move comments
3503 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
3504 of AC_PROG_INSTALL. Output a message saying that we're checking
3505 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
3506 MKDIR_P instead of AC_SUBST.
3507 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
3508 Special magic for MKDIR_P, too.
3509 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
3510 a dnl.
3511 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
3513 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
3515 Sync from Automake, as follows:
3517 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3518 * config/install-sh: Initialize IFS, so field splitting isn't
3519 turned off later.
3520 * config/mkinstalldirs: Likewise.
3521 * config/missing: Remove superfluous quotes. Replace all uses of
3522 `[' by `test', for consistency, and for..
3523 * config/missing (sed_minuso, sed_output): New variables.
3524 (autom4te, help2man, makeinfo): Use them. Unifies detection of
3525 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
3526 Fixes `missing' to detect `--output' for help2man. Fixes
3527 PR automake/483. Report by Dennis J. Linse.
3528 (autom4te): Document in `missing --help'.
3530 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3532 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
3533 * config/install-sh: Don't use 'path' to talk about file names,
3534 as per GNU coding standards. Close a race condition reported by Ralf
3535 Wildenhues and Stepan Kasal. There is still a race condition
3536 on hosts that predate Posix 1003.1-1992, but we can't help this.
3537 Don't mishandle weird characters like space on pre-Posix hosts.
3538 Invoke mkdir at most once per dir arg on pre-Posix hosts.
3539 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
3540 AC_PROG_MKDIR_P from AS_MKDIR_P.
3541 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
3542 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
3543 earlier editions are not (including Automake 1.8.3).
3544 Do not suggest mkinstalldirs for thread-safety.
3545 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
3546 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
3547 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
3548 presence of special characters and race conditions.
3549 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
3550 in Autoconf's name space.
3552 2006-05-10 Bruno Haible <bruno@clisp.org>
3553 and Paul Eggert <eggert@cs.ucla.edu>
3555 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
3556 from Automake with minor changes.
3557 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
3559 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3561 * config/install-sh: Update to Automake CVS version, as follows:
3562 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3563 * lib/install-sh: Simplify the expr implementation of dirname.
3564 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
3565 * lib/install-sh: Handle --, and diagnose unknown options.
3567 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3569 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
3570 `./autom4te' to create `./testsuite', since the `all' target
3571 will ensure its presence, but `installcheck' should not create
3572 the uninstalled wrappers.
3574 * tests/torture.at (Unusual Automake input files): Skip if we
3575 detect automake < 1.8.
3577 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3579 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
3580 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
3581 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
3582 * NEWS: Update.
3584 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3586 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
3587 munge (multiple) white space and other oddities.
3588 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
3589 single quotes in variable assignment.
3590 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
3591 and similar failures by adding multiple spaces, tabs, and other
3592 special characters.
3593 Report and different test suggested by Francesco Romani
3594 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
3596 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
3597 single quotes, we only need to search for single quotes; this
3598 both simplifies the search pattern, and makes us less
3599 susceptible to `echo' variations for arguments not containing
3600 single quotes.
3601 (_AC_ARG_VAR_VALIDATE): Likewise.
3603 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3605 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
3606 `$*' and IFS concatenation issue with traditional shells and
3607 bash-2.04. Report by Seanster@Seanster.com.
3609 2006-05-03 Bruno Haible <bruno@clisp.org>
3611 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
3612 precisely which Mac OS X versions have the od problem.
3614 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3616 * doc/autoconf.texi: Use @option systematically.
3618 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3619 and Bruno Haible <bruno@clisp.org>
3621 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
3622 about 'od'.
3623 (Integer Overflow): Mention the special case of integer division
3624 overflow.
3626 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3628 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
3629 traditional shells like the Solaris one that do not use the
3630 first IFS character for assembling `$*'.
3631 Prompted by a related report from autoconf_bug@nro.ca.
3633 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
3634 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3636 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
3637 Mention more problems with the -e option.
3639 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3641 * NEWS: Typo.
3642 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
3644 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
3645 in URLs to improve DVI formatted output (requires texinfo 4.6).
3646 (System Services, Systemology, Shellology): Likewise.
3647 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
3648 output.
3650 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
3651 continuous text.
3652 (Runtime): Fix macro argument names to match description:
3653 `action-if-found' -> `action-if-true' and similarly.
3654 (Obsolete Macros): Likewise.
3655 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
3656 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
3657 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
3659 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3661 * doc/autoconf.texi (Limitations of Make): Clean up markup.
3663 * ChangeLog: Typo.
3664 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
3665 DVI output.
3667 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3669 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
3670 /bin/sh set unsorted output.
3671 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
3672 * tests/local.at: Likewise.
3674 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
3676 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
3677 (Integer Overflow, Null Pointers, Buffer Overruns):
3678 (Floating Point Portability, Exiting Portably): New sections.
3679 (Writing Test Programs): Fix some langauge. Recommend exiting
3680 with status 1, not merely nonzero. Clarify exit declaration.
3681 (Run Time): Move C exit status stuff to new Exiting Portably section.
3682 (Systemology): Mention Posix and levenez. Update v7 reference.
3683 (Portable Shell): Mention the Posix shell.
3685 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3687 * bin/autoconf.as (me): Replace by as_me.
3689 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
3691 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
3692 since as_me isn't set yet.
3694 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3696 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
3697 a few minor bugs in this area.
3699 * doc/autoconf.texi (Programming in M4sh): Comment out the
3700 documentation of AS_BASENAME, for now.
3701 (Shell Substitutions): Do not use AS_DIRNAME in an example.
3702 (Limitations of Builtins) <basename>: Do not refer to
3703 AS_BASENAME.
3704 * bin/autoconf.as (me): Don't use AS_BASENAME.
3705 (dir): Remove the unused variable.
3706 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
3707 AS_DETECT_REQUIRED. All uses changed.
3708 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
3709 All uses changed.
3710 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
3711 (AS_BASENAME): Use "basename --" to protect against leading "-".
3712 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
3713 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
3714 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".

3720 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3722 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
3723 of "run time" and "run-time" changed to "runtime", for consistency.
3724 * lib/autoconf/fortran.m4: Likewise (in comment).
3725 * lib/autoconf/functions.m4: Likewise.
3726 * lib/autoconf/general.m4: Likewise.
3727 * lib/autoconf/headers.m4: Likewise.
3729 * doc/autoconf.texi (Run Time): Document the exit status situation
3730 with more accuracy and detail.
3732 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3734 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
3735 Archive is not officially `GNU' any more. Update URL.
3736 (Defining Directories): Likewise
3737 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
3739 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3741 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
3742 newline from the `trap' code to finish `config.log'; the NetBSD
3743 /bin/sh resets the exit status after an empty command, as
3744 documented in doc/autoconf.texi.
3745 Reported by Dalibor Topic <robilad@kaffe.org>.
3747 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
3749 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
3750 Suggested by Bruno Haible.
3752 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
3754 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
3755 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
3756 Instead, just list the shells that we know work.
3757 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
3758 changed. Be more cautious about the _cv_ variable.
3759 * tests/tools.at (Syntax of the shell scripts): Check the
3760 _cv_ variable once, at first, to avoid an internal autoconf error
3761 when sh -n does not work.
3763 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3765 * lib/Autom4te/FileUtils.pm: Sync from Automake.
3767 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
3769 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
3770 use ">&-" since we're only 99.999% sure that this is portable,
3771 and since the MinGW bug is fixed in a different way.
3772 * lib/autotest/general.m4 (AT_INIT): Likewise.
3774 2006-04-16 Stepan Kasal <kasal@ucw.cz>
3776 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
3777 before opening config.log, to avoid hitting a bug on MinGW.
3779 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
3781 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
3782 AS_MESSAGE_LOG_FD before reopening it onto the log file.
3783 This works around a MinGW bug reported by Eric Paire.
3784 Make sure that all writes to the log file append to it,
3785 rather than possibly losing data.
3786 * lib/autotest/general.m4 (AT_INIT): Likewise.
3788 2006-04-14 Stepan Kasal <kasal@ucw.cz>
3790 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
3791 description.
3793 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3795 * NEWS: Update.
3797 * configure.ac (AC_INIT): Bump to 2.59d.
3799 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3801 Version 2.59c.
3803 * Makefile.maint (news-date-check): Do not require a leading `*'
3804 before the release date in NEWS.
3806 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3807 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3809 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
3810 the instantiated file do not contain the string 'datarootdir'
3811 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
3812 @mandir@, replace the reference '${datarootdir}' by the value.
3813 * tests/torture.at (datarootdir workaround): New test.
3814 * NEWS: Advertise this temporary fixup.
3815 Based on a patch by Bruno Haible, reported and analyzed by
3816 Paul Eggert and Noah Misch.
3818 2006-04-12 Eric Blake <ebb9@byu.net>
3820 * tests/autotest.at (Debugging a failed test): Fix comment.
3822 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3824 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
3825 all the changes since 2006-04-07.
3827 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3829 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
3830 succeeded, but `ln -s file dir' failed, take care to remove the
3831 leftover target before the next test, to prevent its spurious
3832 failure; also make sure `ln file dir' works before selecting it.
3833 Thanks to Keith Marshall for pointing this out.
3834 * THANKS: Update.
3836 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
3837 assignments in `at_debug_args', so that we put them correctly
3838 in the `run' script.
3839 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
3840 Reported by Eric Blake.
3842 2006-04-11 Eric Blake <ebb9@byu.net>
3844 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
3845 top-level tests after micro-suite has been run. Used in...
3846 (Debugging a successful test, Debugging script and environment),
3847 (Debugging a failed test): ...these new tests. The first of these
3848 is fixed by...
3849 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
3850 macro, split out from...
3851 (AT_INIT): ...here, so that using -d also generates a run script.
3852 Document that -d inhibits top-level logging.
3853 * doc/autoconf.texi (testsuite Invocation): Document that -d only
3854 inhibits top-level logging; debug scripts are created.
3856 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
3857 check.
3858 * tests/autotest.at (Empty test, Empty check): New test to check it.
3860 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
3861 from gcc.
3863 2006-04-10 Stepan Kasal <kasal@ucw.cz>
3865 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
3866 the files if a problem appears. Make the empty *.at files
3867 read-only, too. Proposed by Ralf Wildenhues.
3869 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3871 * config/Makefile.am: Add comment to force updated Makefile.in.
3873 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
3874 space only patch to this file, this patch causes the Makefile.in
3875 files that include freeze.mk to be updated, and thus have a
3876 newer time stamp again, which in turn makes a pristine CVS
3877 checkout have correct time stamps.
3879 * Makefile.maint (cvs-sv): New macro, to be used..
3880 (config.guess-url_prefix, config.sub-url_prefix)
3881 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
3882 point to CVS text checkout of Gnulib files.
3883 (copyright-check): Bump current year.
3884 (announcement): Do not hard-wire `./announce-gen'.
3885 (cvs-update): Propagate failures of `cvs' and `move-if-change'
3886 correctly.
3887 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
3888 `chmod +x'.
3889 (wget_files): Update config.guess, config.sub, texinfo.tex by
3890 `wget-update', now that their URLs work again.
3892 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3894 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
3895 Problem noted by Paul D. Smith.
3897 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3899 * doc/autoconf.texi: Remove unused words from word list.
3900 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
3901 .x-sc_trailing_space: New files.
3903 * doc/standards.texi: Sync from gnulib.
3905 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
3906 `LIBOBJDIR' as experimental.
3908 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
3909 with a target directory; it's internally implemented as `cp'
3910 anyway, but since Autoconf advertises the possibility to use
3911 a target directory when LN_S is `ln -s', we need to find out.
3912 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
3913 analyzed by Keith Marshall <keith.marshall@total.com>.
3915 * THANKS: Update.
3917 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3919 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
3920 confdefs.h as-is. In general, if it has backslash-newline or the
3921 like, then it doesn't work either to sort or to remove empty
3922 lines.
3924 2006-04-09 Stepan Kasal <kasal@ucw.cz>
3926 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
3928 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
3930 * lib/autom4te.in (Automake-preselections): Preselect
3931 _AM_SUBST_NOTMAKE.
3933 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3935 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
3936 apostrophe within a single-quoted string, as this is the usual
3937 tradition and is easier to read than '"'"'. Don't rely on the
3938 shell treating "$/" like '$/'. Use a more-consistent indenting
3939 style for the trap.
3941 2006-04-09 Eric Blake <ebb9@byu.net>
3943 * tests/autotest.at (Backquote command substitution),
3944 (Multiline backquote command substitution): Remove mistaken
3945 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
3946 applied...
3947 (Parenthetical command substitution, Multiline parenthetical
3948 command substitution): here.
3950 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3952 Import macros from gnulib (often changing their name).
3954 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

3966 (Pointers): Add Gnulib URL.
3967 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
3968 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
3969 Gnulib section.
3970 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
3971 suggest a #define rather than a typedef for _Bool, and mention
3972 Gnulib rather than trying to substitute stdbool code.
3973 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
3974 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
3975 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
3976 AC_STRUCT_DIRENT_D_TYPE.
3977 (Particular Types): Mention stdint.h and inttypes.h as standard
3978 headers too.
3979 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
3980 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
3981 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
3982 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
3983 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
3984 (C Compiler): Move AC_C_LONG_DOUBLE to ...
3985 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
3986 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
3987 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
3988 (Coding Style). Don't mention m4_expand_once.
3989 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
3990 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
3991 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
3992 (AC_CHECK_FUNCS): Use it.
3993 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
3994 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
3995 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
3996 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
3997 (AC_HEADER_ASSERT): New macro.
3998 (AC_HEADER_STDBOOL): Don't assume "#error" works.
3999 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
4000 Catch a bug in an HP-UX C compiler.
4001 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
4002 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
4003 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):

4005 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
4006 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
4007 New macros.
4009 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
4010 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
4012 2006-04-08 Stepan Kasal <kasal@ucw.cz>
4014 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
4015 of the warning introduced by the 2001-08-28 change.
4017 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
4018 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4020 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
4021 variables shall be overriden by the cache.
4022 * tests/torture.at (AC_ARG_VAR): Test also with a first value
4023 that contains braces.
4025 2006-04-07 Stepan Kasal <kasal@ucw.cz>
4027 Revert the patch from 2006-04-01 and only improve
4028 _AS_DETECT_BETTER_SHELL:
4030 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
4031 skip nonexistent directories.
4032 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
4033 only shell candidates which exist.
4034 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
4035 * lib/autotest/general.m4 (AT_INIT): No need to give three
4036 parameters to _AS_PATH_WALK.
4038 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
4039 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4041 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
4042 distinguish m4sugar macros.
4043 * tests/tools.at (autoupdating with aclocal and m4_include):
4044 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
4045 test case by Noah Misch <noah@cs.caltech.edu>.
4047 2006-04-07 Stepan Kasal <kasal@ucw.cz>
4049 Revert my change from 2006-03-17, in other words:
4050 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
4051 and DUALCASE=1.
4052 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
4053 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
4054 it is set.
4056 2006-04-07 Eric Blake <ebb9@byu.net>
4058 * doc/autoconf.texi (Programming in M4sh): Document that
4059 AS_MKDIR_P exits the script on failure.
4060 * lib/autotest/general.m4: Remove redundant AS_ERROR.
4062 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4064 * config/elisp-comp, config/install-sh, config/mdate-sh,
4065 config/missing, config/mkinstalldirs: Sync from Automake.
4067 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
4068 from Automake.
4070 * doc/make-stds.texi: Sync from gnulib.
4072 2006-04-06 Eric Blake <ebb9@byu.net>
4074 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4075 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
4076 2006-04-01.
4078 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
4079 Eric Blake <ebb9@byu.net>,
4080 Paul Eggert <eggert@cs.ucla.edu>,
4081 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4083 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
4084 whether `set' quotes correctly: redirect stderr of the tested
4085 `set', and use a subshell, for Ultrix; use `sed' instead of
4086 `grep' for zsh `set' which may write binary output; match only
4087 at the beginning of a line, to avoid false positives.
4088 In order to avoid false positives by unrelated variables with
4089 multiline content, put the dump algorithm in a subshell and
4090 unset all variables containing newlines (except some which are
4091 special to the shell). Warn about cache variables that are
4092 unset.
4094 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4096 * config/config.guess, config/config.sub, config/texinfo.tex:
4097 Sync from upstream.
4099 * tests/mktests.sh: Reword comments.
4101 * tests/mktests.sh: Only skip internal macros starting with
4102 `_AC_' or `__AC_'. Noted by Stepan Kasal.
4103 Update exclusion lists for the test suite to this end:
4104 (AC_ARG_VAR): Do test this now.
4105 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.

4295 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4296 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4297 ac_file to the name of the default output file and call
4298 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4299 initial `rm' of the candidate files...
4300 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4301 the same list in subsequent `rm' calls, and for the temporary
4302 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4303 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4304 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4305 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4306 no longer needed) by libtool. Make it a cache check.
4307 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4308 copied here by mistake.
4309 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4310 _AC_COMPILER_EXEEXT.

4347 subordinate tools.
4348 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
4349 * doc/autoconf.texi (autoreconf Invocation): Document it.
4351 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

4439 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
4441 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5022 ac_clean_files and LIBOBJS.
5024 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5026 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
5027 Factor functionality to..
5028 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
5029 `AC_SUBST($1)' in the public version.
5030 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
5031 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
5032 ac_pt_* variables.
5034 2005-11-01 Stepan Kasal <kasal@ucw.cz>
5036 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
5037 filesystems.
5039 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5041 * NEWS: Move AH_HEADER mention to right place.
5043 2005-10-27 Stepan Kasal <kasal@ucw.cz>
5045 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
5046 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
5048 2005-10-25 Stepan Kasal <kasal@ucw.cz>
5050 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
5051 conftst2.$ac_objext.
5052 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
5054 2005-10-24 Stepan Kasal <kasal@ucw.cz>
5056 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
5057 conftest.o, to see whether the compiler really obeys; rm the object
5058 file before and after the test and register it with ac_clean_files.
5059 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
5061 2005-10-21 Stepan Kasal <kasal@ucw.cz>
5063 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
5064 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
5065 code so that the most common case requires less forks.
5067 2005-10-20 Stepan Kasal <kasal@ucw.cz>
5069 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
5070 not portable; thanks to Paul Eggert and Alexandre.
5072 * NEWS: Fix an old typo.
5074 2005-10-20 Jim Meyering <jim@meyering.net>
5076 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
5077 the latter'', in two places.
5079 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
5081 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
5082 AC_LANG_PROGRAM, fixing a typo. Don't give details about
5083 the inner workings of AC_LANG_FUNC_LINK_TRY.
5084 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
5085 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
5086 by the function rather than ignoring it.
5087 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
5088 comparing its address. Intel's interprocedural optimization was
5089 outsmarting the old heuristic. Problem reported by
5090 Mikulas Patocka.
5092 2005-10-19 Stepan Kasal <kasal@ucw.cz>
5094 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
5096 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
5098 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

5101 2005-10-04 Stepan Kasal <kasal@ucw.cz>
5103 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
5104 before removing it (chmod -R u+rwx); there are three instances of this.
5106 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5107 Stepan Kasal <kasal@ucw.cz>
5109 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
5110 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
5111 make its content writable before removing it. Remove an errorneous
5112 comment from the end, where the logs of the failed tests are copied
5113 to the main log file.
5115 2005-09-27 Stepan Kasal <kasal@ucw.cz>
5117 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
5118 in case the computer is too quick. Double quote the configure.ac
5119 snippets.
5121 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
5122 problems if the testsuite were running too fast.
5124 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5126 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5127 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5128 (which belong to Xt, not X itself). See Debian bug 327655.
5129 * NEWS: Mention this.
5131 2005-09-07 Stepan Kasal <kasal@ucw.cz>
5133 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
5135 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
5137 * config/move-if-change: Don't output "$2 is unchanged";
5138 suggested by Ben Elliston. Handle weird characters correctly.
5140 2005-09-06 Stepan Kasal <kasal@ucw.cz>
5142 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
5143 calls, so that the final expansion of this macro is shorter.
5144 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
5145 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
5146 the cleanup there. Use AS_VAR_* macros, to be more general.
5147 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
5149 * lib/autoconf/general.m4: Use AS_IF where appropriate.
5151 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
5153 2005-09-01 Stepan Kasal <kasal@ucw.cz>
5155 * doc/autoconf.texi (Configuration Headers): Add an index entry
5156 for AH_HEADER.
5158 2005-08-26 Pavel Roskin <proski@gnu.org>
5160 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
5161 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
5162 running xmkmf.
5164 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
5166 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
5167 The previous patch didn't work, so try a better one.
5169 2005-08-26 Stepan Kasal <kasal@ucw.cz>
5171 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
5172 in the example. Reported by Bruno Haible.
5173 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
5174 "if $undefined_var;" succeeds with my shell.
5176 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
5177 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
5178 but change the m4_divert_text to m4_divert_once.
5180 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
5182 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
5183 Work around bug in Solaris /usr/xpg4/bin/awk.
5184 The bug is present in at least Solaris 8 through 10.
5186 2005-08-24 Stepan Kasal <kasal@ucw.cz>
5188 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
5189 some evil values and relying on the fact that $* concatenates the
5190 parameters by the first character from IFS.
5192 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5193 Stepan Kasal <kasal@ucw.cz>
5195 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
5196 first header appears, define AH_HEADER.
5197 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
5198 Update limitations about when to call AC_CONFIG_HEADERS.
5199 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
5200 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
5201 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
5202 ``Configuration Actions''; fix their index entries.
5204 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
5205 options correctly. Process N-M as M-N if M is smaller than N.
5206 Process ranges correctly so that N-N will run only N.
5207 Sort and uniquify the tests that will be run. If there is more
5208 than one test, reinsert the banners for the tests.
5209 * tests/autotest.at (Keywords): Unmark XFAIL.
5211 2005-08-23 Stepan Kasal <kasal@ucw.cz>
5213 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
5214 before passing the macro name to AH_TEMPLATE.
5216 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
5217 now opens log after option processing; in particular, --version
5218 and --help do not touch config.log.
5220 * Makefile.maint: Revert the change from 2005-08-12.
5222 2005-08-22 Stepan Kasal <kasal@ucw.cz>
5224 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
5225 common code to...
5226 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
5228 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5230 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
5231 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
5232 Language cleanup.
5234 * doc/autoconf.texi (Defining Symbols, Changed Results):
5235 Prepend to LIBS, not append, in examples.
5237 2005-08-16 Stepan Kasal <kasal@ucw.cz>
5239 When building in place, set srcdir="."; suggested by Tim Van Holder.
5241 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
5242 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
5243 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
5244 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
5245 does not mean "no --srcdir option".
5247 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5249 * tests/autoscan.at (autoscan): New file.
5250 * tests/suite.at: Use it.
5251 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
5252 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
5254 * tests/autotest.at (Keywords): Test keywords combinations.
5256 2005-08-12 Stepan Kasal <kasal@ucw.cz>
5258 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
5259 add "2>&1"; gzip 1.2.4 prints help on stderr.
5261 2005-07-27 Stepan Kasal <kasal@ucw.cz>
5263 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
5264 was pushdef'ed twice while popped only once. Push it only once.
5265 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
5267 2005-07-26 Stepan Kasal <kasal@ucw.cz>
5269 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

5274 * Makefile.maint: Update from Bison.
5276 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
5277 "<tab>" in comment, so that the point is understandable.
5279 2005-07-25 Stepan Kasal <kasal@ucw.cz>
5281 Rewrite substantial part of lib/autoconf/status.m4.
5282 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
5283 and CONFIG_COMMANDS are not processed in four separate loops.
5284 Instead, there is one main loop. This alows that the common code
5285 is expanded only once, thus config.status (and configure) is smaller.
5287 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
5288 the AC_LIST_FILES and cousins macros are no longer used.
5290 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
5291 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
5292 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
5293 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
5294 contain the initialization, nor the for loop, nor the associated
5295 commands; all these go to ...
5296 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
5297 _AC_OUTPUT_CONFIG_STATUS.
5298 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
5299 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
5300 (_AC_OUTPUT_FILE): The creation of the sed script ...
5301 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
5302 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
5303 _AC_OUTPUT_MAIN_LOOP.
5304 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
5305 _AC_CONFIG_COMMANDS): Use ...
5306 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
5307 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
5308 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
5309 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
5310 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
5311 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
5312 ... new macros.
5313 (_AC_CONFIG_UNIQUE): Update.
5314 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
5315 Replaced by this ...
5316 (_AC_LIST_TAGS): ... new common macro.
5317 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
5318 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
5319 (_AC_LIST_TAG_COMMANDS): ... new common macro.
5320 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
5321 this didn't belong to the `config commands' section.
5322 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
5323 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
5324 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
5325 to the `config commands' section either.
5326 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
5327 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
5329 ... and many changes to the comments nearby.
5331 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
5332 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
5333 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5334 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
5335 (#define header templates): The comment at the top of the generated
5336 header now includes the name(s) of the source file(s).
5338 Several unrelated small changes:
5340 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
5341 parameter to AC_DIAGNOSE.
5342 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
5343 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
5344 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
5345 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
5346 with AU::AC_OUTPUT.
5347 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
5348 in AC_OUTPUT doesn't double-quote it either.
5349 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
5350 parameters.
5352 2005-07-10 Stepan Kasal <kasal@ucw.cz>
5354 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
5355 versions of Portland Group compiler produce single- and double-quoted
5356 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
5357 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
5359 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
5361 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
5362 This is a corrected version of yesterday's patch.
5364 2005-07-07 Stepan Kasal <kasal@ucw.cz>
5366 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
5367 path, too; insert a "===" to emphasize the line.
5369 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
5370 ac_cv_build_alias to ac_build_alias.
5371 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
5373 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
5374 change eliminates it. Problem reported by Alexandre Duret-Lutz.
5375 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
5376 (AC_ARG_VAR): ... here.
5377 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
5378 target_alias.
5380 Keep a list of all precious variables and process them with one simple
5381 for loop, instead of expanding all commands, or, OTOH, complicated
5382 processing of output of "set".
5383 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
5384 variable names in new macro...
5385 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
5386 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
5387 a loop to assign all ac_env_* and ac_cv_env_* variables.
5388 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
5389 to INIT_PREPARE.
5390 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
5391 its value to shell variable ac_precious_vars and call
5392 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
5393 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
5394 _AC_ARG_VAR_VALIDATE.
5396 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
5397 and the AC_SUBSTs ...
5398 (AC_INIT): ... here.
5400 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
5401 the ac_subst_files section in config.log.
5403 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
5405 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

5410 * tests/c.at (C keywords): Test AC_C_TYPEOF.
5412 Fix problems reported by Nicolas Joly.
5413 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
5414 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
5415 They are generated by the Tru64 v5.1B shell.
5417 2005-07-05 Stepan Kasal <kasal@ucw.cz>
5419 Fix my changes from 2005-07-01; reported by Noah Misch.
5420 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
5421 description, the macro now accepts only a single tag.
5422 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
5424 Fix cases when the varsions of Autoconf and Autotest don't match.
5425 Reported by Noah Misch.
5426 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
5427 at_top_builddir, for compatibility with older autotest.
5428 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
5429 is not set, use at_top_builddir, for compatibility with older
5430 versions of autoconf.
5432 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
5434 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
5435 Problem reported by Patrick Welche.
5437 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
5439 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
5440 sed substitution command, so that we allow | in program prefixes
5441 and program suffixes. (& is a problem anyway; we're not fixing
5442 that here.)
5443 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
5444 configure_input, top_builddir, srcdir, etc.
5445 * lib/autotest/general.m4 (AT_INIT): Likewise, for
5446 PATH_SEPARATOR in AUTOTEST_PATH.
5448 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
5450 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
5451 for loop over config.site files using `set', to allow
5452 directory names containing IFS characters.
5454 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
5456 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
5457 directories with weird names. Apparently some people like living
5458 on the edge. However, improve the test that "pwd" actually does
5459 report a name for the working directory.
5460 * NEWS: Remove the claim that we test for funny chars in dir names.
5462 2005-07-01 Stepan Kasal <kasal@ucw.cz>
5464 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
5465 replaced ...

5474 about #include <config.h>.
5475 (Generic Functions): Mention the Gnulib project.
5476 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
5478 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
5479 document to output the default config_* lists to config.status.
5480 Don't recognize option --file, if the functionality is not there.
5481 Likewise for --header; moreover, recognize --he and --h as shortcuts
5482 for --help in that case.
5484 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
5485 matches the order of execution. No code changed.

5507 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
5508 (AC_SUBST): Call it.
5509 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
5510 the directory specific variables; but don't call it for configure_input.
5512 2005-06-28 Derek Price <derek@ximbiot.com>
5514 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
5515 addition.
5517 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
5519 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
5520 directory have inherent problems with special characters like spaces,
5521 due to limitations in Make syntax. Problem reported by Alexandre
5522 Duret-Lutz.
5523 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
5524 Also, fix Tru64 porting problem with shell patterns,

5536 from Justace Clutter.
5537 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
5538 variable into diagnostic. Make the diagnostic an error, not a warning,
5539 because we really don't support spaces and suchlike in dir names.
5540 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
5541 Don't worry about backslashes in srcdir; it can't happen now.
5542 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
5543 Simplify ac_optarg handling.
5544 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

5554 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
5555 that '\|' is not allowed in BREs; recommend using newline separated
5556 list of patterns instead of multiple -e options.

5566 2005-06-21 Stepan Kasal <kasal@ucw.cz>
5568 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
5569 b, t, r, w commands require single space, while : cannot have any.
5570 (Special Shell Variables): Fix sed code this in the example.
5571 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
5572 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
5574 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
5575 expand to the empty list. Don't use two pairs of m4_changequote,
5576 it's not necessary.
5578 2005-06-20 Derek Price <derek@ximbiot.com>
5580 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
5582 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
5584 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
5585 * doc/autoconf.texi:
5586 Don't mention Solaris versions so much, if a
5587 problem is common to all extant versions of Solaris. Say "SunOS
5588 4" instead of "SunOS" for SunOS 4.
5589 (awk): Mention more of the limitations of traditional Awk.
5590 (cat): Don't talk about cat -v.
5592 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
5594 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
5595 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
5596 but the implementation is entirely different and is designed
5597 to be compatible with glibc strverscmp.
5598 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
5600 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
5601 on Mac OS X 10.4 reported by Peter O'Gorman in:
5602 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
5603 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
5604 Use shell builtins rather than 'expr', to work around expr bug.
5606 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
5608 * doc/autoconf.texi: "filesystem" -> "file system".
5609 "behaviour" -> "behavior".

5611 * lib/autoconf/general.m4: Omit blank after ":" sed command,
5612 as per POSIX.
5613 * lib/m4sugar/m4sh.m4: Likewise.
5614 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
5615 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
5617 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
5618 (.x.1): Ignore the time stamp in the .TH line when deciding whether
5619 to update the man page. That way, we don't have to check in new
5620 man pages every month.
5622 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
5623 quotes and backslashes. Patch from Derek Price.

5628 AS_TR_SH.
5630 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
5632 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
5633 -u, since it outputs chatter if the input files are the same.
5634 Problem reported by Ralf Menzel.
5636 2005-06-08 Derek Price <derek@ximbiot.com>
5638 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
5639 renaming them since they are about to be redefined anyhow.
5641 2005-06-08 Derek Price <derek@ximbiot.com>
5643 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
5644 redefined M4 macros to this node. Document m4_include & m4_sinclude.
5645 Move m4_undefine to alphabetical order.
5647 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
5649 * README: Recommend GNU M4 1.4.3 or later.
5650 * doc/autoconf.texi (Introduction): Likewise.
5651 Reword to avoid some formatting glitches.
5652 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
5653 Clarify explanation of HP compiler bug.
5654 Redo example output tp match current CVS snapshot.
5655 Use @example.org in email addresses when the examples
5656 might get inadvertently cut-and-pasted into user code.
5657 Remove example of autom4te usage that doesn't seem to work now.
5658 Use modern AC_INIT (except when the example is meant to be
5659 shown with Autoconf 2.13).
5660 Update ksh info for Solaris 9 and later.
5661 KB -> kB.
5662 Modernize description of Automake versions a bit.
5663 Don't claim a future version of Autoconf is near.
5664 * doc/install.texi: Reword to avoid some formatting glitches.
5666 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5668 * doc/autoconf.texi: Add [] to examples, so that the manual
5669 follows its own advice about quoting better.
5670 Reword to avoid some formatting glitches.
5671 * doc/installt.exi: Reword to avoid some formatting glitches.
5673 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
5674 Tru64 ksh pattern matching bug. Reported against Libtool by
5675 Albert Chin <libtool@mlists.thewrittenword.com> and
5676 Nicolas Joly <njoly@pasteur.fr>.
5678 2005-06-06 Stepan Kasal <kasal@ucw.cz>
5680 m4_cdr of one-member list was [[]] (one-member list containing an
5681 empty string) instead of [] (an empty list. Callers were skewed to
5682 match this misbehaviour. As a consequence of this:
5683 - m4_foreach([x], [], [foo]) expanded to `foo', while
5684 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
5685 This bug has been fixed:
5687 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
5688 expand to an empty string; print error msg if called without
5689 an argument list.
5690 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
5691 misbehaviour; handle [] and [[]] correctly.
5693 2005-06-06 Stepan Kasal <kasal@ucw.cz>
5695 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

5697 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
5699 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
5701 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
5702 swallow records with more than 99 fields.
5703 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
5704 parse the long line.
5706 2005-06-04 Stepan Kasal <kasal@ucw.cz>
5708 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
5709 swallow literals longer than 399. Reported by Ralf Wildenhues.
5710 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
5711 to workaround this limitation.
5713 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
5715 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
5716 to gfortran, and make these the first two compiler names
5717 checked (following the general autoconf preference for gcc).
5719 2005-06-03 Stepan Kasal <kasal@ucw.cz>
5721 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
5722 (DISTCLEANFILES): Remove $(check_SCRIPTS).
5723 (testsuite): Make sure autotest.m4f is up-to-date before using it.
5725 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
5727 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
5728 expression of unbounded size when processing the --list
5729 option. This runs afoul of a limit of 399 bytes per regular
5730 expression on AIX. Problem reported by Ralf Wildenhues.
5732 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
5734 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
5735 * doc/autoconf.texi (Particular Headers): Reword example
5736 for multiline stdbool replacement.
5737 (Setting Output Variables): Reword text a bit. Don't
5738 give all the details about |#_!!_#|.
5739 Reword description of line replacement.
5741 2005-05-31 Dan Manthey <dan_manthey@partech.com>
5743 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
5744 now contain newlines, and substituted files must be referenced on
5745 a line alone; the sed scripts to substitute them are now very
5746 different.
5747 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
5748 commands can be put in a sed script portably.
5749 * doc/autoconf.texi (Setting Output Variables): Document above
5750 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
5751 use of multiline substitution.

5761 * tests/local.at: Don't attempt to check for negated character
5762 classes in shell scripts. The test was too brittle.
5764 2005-05-25 Stepan Kasal <kasal@ucw.cz>
5766 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
5767 * doc/autoconf.texi (Limitations of Builtins): Document this
5768 limitation.
5770 2005-05-24 Stepan Kasal <kasal@ucw.cz>
5772 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
5773 common code; used in many places in the tree.

5775 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
5777 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
5779 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
5780 messages when ac_unique_file is not found.
5781 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
5782 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
5783 commands, for consistency with AC_MSG_ERROR and such.
5785 * bin/autoconf.as: Make more use of "shift 2" in option processing.
5787 * bin/Makefile.am: Merge the two rules for creating scripts.

5795 2005-05-20 Stepan Kasal <kasal@ucw.cz>
5797 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
5798 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
5799 (ac_top_builddir): ... this ...
5800 (ac_top_build_prefix): ... to this; the old name is also kept, for
5801 backward compatibility.
5802 (ac_top_builddir_sub): New variable, without the trailing slash,
5803 always nonempty.
5804 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
5805 * doc/autoconf.texi (Configuration Actions): Rename
5806 ac_top_builddir to ac_top_build_prefix.
5807 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

5816 2005-05-17 Stepan Kasal <kasal@ucw.cz>
5818 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
5819 argument to m4_foreach. I guess it was necessary in the past,
5820 but I think it's a no-op now.
5822 2005-05-17 Stepan Kasal <kasal@ucw.cz>
5824 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
5825 ``cat <<_ACEOF'' commands to one.
5826 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
5827 * lib/autoconf/status.m4: On various places, use expr instead of
5828 ``echo|sed.''
5829 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
5830 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
5831 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
5832 a range.
5833 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
5834 the wrong patterns between ``case'' and ``esac.'' The previous
5835 code had false positives.
5837 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
5839 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
5840 as on 2005-05-02.
5841 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
5842 Mention LIBOBJDIR.

5903 * doc/autoconf.texi (Autoconf Language): Be more precise about
5904 quoting rules. Problems noted by Stepan Kasal.
5905 Also, throughout this document, be more careful about white space.
5906 "blank", "white space", and "space" all have different meanings
5907 and we should be careful to say what we mean.
5909 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
5911 Fix C++ related problems reported by Werner Lemberg.
5912 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

5928 set by latest automake.
5930 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
5932 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
5933 outputs 0 on GNU/Linux these days.
5935 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
5937 * doc/autoconf.texi (Autoconf Language): Add more description
5938 about quoting heuristics.
5939 (Limitations of Builtins): Describe "set -" problems.
5941 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5943 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
5944 not newline.
5946 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
5947 by AC_DEFINE; it was a mistake.
5948 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
5950 2005-04-25 Stepan Kasal <kasal@ucw.cz>
5952 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
5954 2005-04-22 Stepan Kasal <kasal@ucw.cz>
5956 * doc/autoconf.texi (External Software): Quadrigraphs are not
5957 processed correctly in AS_HELP_STRING; avoid this in the examples.
5958 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
5959 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the

5961 (m4_strip): Update the explanation.
5963 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
5965 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
5966 Remove core.conftest.* too; it's generated by Tru64 5.1.
5967 Problem reported by Jennis Pruett.
5968 * lib/autoconf/functions.m4
5969 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):

6017 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
6018 Merge `-z option' as well for the benefit of Solaris link flags. Pass
6019 whole-archive (-zallextract, -zdefaultextract) options in the hope of
6020 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
6021 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
6023 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
6025 * NEWS: The configure command now warns you if you attempt to use
6026 a directory whose name contains a special character like space,
6027 newline, or "\".
6028 * doc/autoconf.texi (Installation Directory Variables): Allow
6029 "," in file names. Do not use \@; it's not a portable regexp.
6030 * bin/Makefile.am (edit): Likewise.
6031 * lib/Makefile.am (edit): Likewise.
6032 * tests/Makefile.am (edit): Likewise.

6042 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
6043 ac_pwd, and quote srcdir.
6044 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
6046 * doc/autoconf.texi: Fix some systematic formatting problems.
6047 ".)" needs a following @: if not at the end of a sentence, and
6048 similarly for "!)". "etc." should be preceded by a comma.
6049 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
6051 2005-03-22 Bruno Haible <bruno@clisp.org>
6053 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
6054 argument is often called 'build-aux'.
6056 2005-03-07 Stepan Kasal <kasal@ucw.cz>
6058 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
6059 macro AC_TRY_LINK is obsolete.
6060 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
6061 `AC_CONFIG_FILES'.
6063 2005-02-24 Stepan Kasal <kasal@ucw.cz>
6065 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
6066 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
6067 from a Common Lisp's `cl'.
6068 (AC_PROG_CXX): Behave according to the documentation: don't
6069 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
6070 make the variable CCC precious; use `cl.exe', not `cl'.
6072 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6073 Alexandre Duret-Lutz <adl@gnu.org>
6075 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
6076 /dev/null, as "configure" shouldn't read stdin, and this insulates
6077 us from problems (e.g., when testing for "cl"). Also, do this
6078 redirection before invoking "hostname" or "uname", and keep the
6079 original input stream available via...
6080 (AS_ORIGINAL_STDIN_FD): ... this new macro.
6081 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
6082 bother with "</dev/null" since it's now done at the top of
6083 'configure'.
6084 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
6085 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

6091 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6093 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
6094 newline if neither \c nor -n work, as that would output two
6095 newlines. Prefer -n to \c. Reported by Stepan Kasal.
6097 2005-02-12 Stepan Kasal <kasal@ucw.cz>
6099 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
6100 This causes that any required macros inside will get before the if.
6101 * doc/autoconf.texi (autom4te.cache): A typo.
6103 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
6105 Undo previous change, except keep the change to
6106 lib/autoconf/programs.m4 that replaced grep with shell
6107 pattern-matching. This is because net-snmp configure reads stdin.
6108 Reported by Noah Misch.
6110 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
6112 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
6113 from /dev/null, as "configure" shouldn't read stdin, and this
6114 insulates us from problems (e.g., when testing for "cl").
6115 Suggested by Alexandre Duret-Lutz. Also, do this redirection
6116 before invoking "hostname" or "uname".
6117 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6118 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
6119 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
6120 "</dev/null" since it's now done at the top of 'configure'.
6121 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6122 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
6123 Also, replace grep with shell pattern-matching, to save a process.
6125 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
6127 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6128 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
6129 avoid thinking that Allegro Common Lisp's "cl" command is a C++
6130 compiler.
6132 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
6134 * doc/autoconf.texi (Limitations of Usual Tools): Document that
6135 grep -q isn't portable. Improve grep -s explanation.
6136 Problem reported by Dan Manthey.
6138 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
6140 * doc/autoconf.texi (Special Shell Variables): Clarify
6141 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
6143 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
6145 * doc/autoconf.texi: Use @acronym for DJGPP.
6146 Fix some @code's that should have been @env's, and vice versa.
6147 Sort environment variable names.
6148 Mention that shells no longer inherit IFS.
6149 Don't recommend PATH_SEPARATOR=';' so strongly.
6150 Mention that $RANDOM might expand to the empty string.
6151 "symlink" and "soft link" -> "symbolic link".
6152 Improve mktemp description (reported by Bruno Haible).
6154 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
6156 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
6157 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
6158 Likewise.

6164 * NEWS: Mention AT_COPYRIGHT.
6166 * tests/local.at (AT_CMP): Use diff directly on input files rather
6167 than copying them.
6169 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
6170 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
6172 2005-02-04 Noah Misch <noah@cs.caltech.edu>

6183 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
6184 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.

6188 excess test name quoting.
6189 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
6190 CPPFLAGS to `configure' instead of setting it in `configure'.
6192 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
6193 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
6194 on some platforms.
6196 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
6197 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

6225 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
6227 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
6228 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
6230 Try not to generated lines of unlimited length, as POSIX places a
6231 2047-byte limit on line length of portable text files.
6232 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
6233 Use newline as a separator, not space.

6244 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
6246 * doc/autoconf.texi (Special Shell Variables): Mention _,

6248 if they contain a lower-case letter. The DUALCASE problem was
6249 reported by Ralf Wildenhues.
6251 * bin/autoconf.as: Don't exit with status 0 after write failure

6291 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
6292 Update the long comment explaining it.
6294 m4_require no longer writes an ``is required by'' line to the
6295 execution stack. It contains only one bit of non-redundant
6296 information: that the macro was required, not called. And even
6297 this bit is useless in most situations: have you ever met a macro
6298 which both calls and requires the same macro?
6300 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
6301 (_m4_defun_pro_outer): ... only via this macro, for the outermost
6302 macro.
6303 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
6304 (m4_expansion_stack_pop): Remove the misplaced comment.
6305 (m4_require): Don't put the ``is required by'' line to the
6306 execution stack; slightly improve the out-of-a-defun error message.
6307 (_m4_divert_grow): New macro, counter for the temporary diversions.
6308 (_m4_require_call): Use it.
6309 * tests/m4sugar.at (m4_require): Expect output without the
6310 ``is required by'' messages.
6312 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
6314 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
6315 rather than x for expr.
6317 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
6318 this is safe.

6331 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
6332 from masters, so that FileUtils.pm's update_file provide --force
6333 support.
6334 * bin/autoheader.in: Pass $force to update_file so that
6335 config.h.in is always recreated when --force.

6339 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
6341 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
6343 * doc/autoconf.texi (Limitations of Builtins): Clarify that
6344 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
6346 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
6348 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
6349 Warn about newline stripping in `` and $(). Update Solaris
6350 version to 9.
6351 (Limitations of Builtins): Use expr "X...", not expr "x...", as
6352 X insulates us from future changes to Posix.
6353 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
6354 stripping.
6356 2005-01-19 Stepan Kasal <kasal@ucw.cz>

6720 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
6721 "char c = '\200';" rather than "char c = 0x80;" as the

6831 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
6832 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
6833 in test makefile.
6834 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
6835 readable; it's not true in OS/2-emx.
6837 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
6839 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
6840 "/usr/include", clear ac_x_includes instead of leaving it as "no"
6841 (trivial change). Problem and patch reported by Andrew Church in:
6842 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
6844 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
6846 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED

6849 Also, fix some minor spacing and punctuation bugs.
6851 2004-09-02 Akim Demaille <akim@epita.fr>
6853 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
6854 "case" to restore ordering.
6855 Reported by Stepan Kasal.

6871 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
6872 texinfo.tex for now (done by hand now).
6873 * Makefile.maint (wget_files, cvs_files):
6874 Remove ansi2knr.c; nobody uses it.
6875 (ansi2knr.c-url_prefix): Remove.
6876 (cvs-update): Fix test for failure. I don't know why it ever
6877 worked...
6879 * doc/autoconf.texi: Update URLs, some of which went stale.
6880 Use @uref rather than @href.
6882 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
6883 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
6885 * config/config.guess, config/config.sub, config/elisp-comp,
6886 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
6887 doc/fdl.texi, doc/standards.texi: Sync with master copy.
6889 * NEWS, TODO, configure.ac, bin/autoscan.in,
6890 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
6891 doc/install.texi, lib/Autom4te/Configure_ac.pm,
6892 lib/Autom4te/FileUtils.pm, lib/autoconf/general.m4,
6893 lib/autoconf/programs.m4, lib/autoconf/status.m4,
6894 lib/autotest/general.m4, lib/m4sugar/m4sh.m4,
6895 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
6896 tests/tools.at, tests/torture.at:
6897 Use "file name" rather than "filename" or "path",
6898 to be consistent with the terminology of the GNU coding standards.
6900 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
6902 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
6903 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
6904 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
6905 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
6907 More fixes to support spaces in the name of the build directory.
6908 This isn't a complete fix but it's an improvement.
6910 * bin/autoconf.as (autom4te_options): New var.
6911 Use it instead of appending to AUTOM4TE, so that we can allow
6912 spaces in the build directory's absolute name.
6913 * bin/autoheader.in ($autoconf): Allow spaces in file names.
6914 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
6915 AT_CHECK_NOESCAPE): Likewise.
6916 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
6917 main program): Likewise.
6919 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
6921 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
6922 From Ralf Corsepius in:
6923 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
6925 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
6927 * doc/autoconf.texi (Function Portability): Document isinf and
6928 and isnan. From a suggestion by Kevin Ryde.
6930 * lib/Autom4te/General.pm (END): Return correct exit status even
6931 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
6933 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
6935 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
6936 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
6937 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
6939 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
6941 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
6942 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
6943 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
6944 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
6945 * lib/autom4te.in (Automake-preselections): Preselect
6946 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
6948 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
6950 * lib/autom4te.in (Automake-preselections): Preselect
6951 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
6952 trace them.
6954 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
6956 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
6957 Tru64.
6958 * doc/autoconf.texi (Shellology): Mention BIN_SH.
6959 Document problem with "`""`" in pdksh POSIX mode.
6961 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
6963 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
6964 with pdksh, too. Problem reported by Patrick Welche via
6965 Gary V. Vaughan.
6966 * doc/autoconf.texi (Shellology): Note that set -o posix is
6967 useful for pkdsh, too.
6969 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
6971 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
6972 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
6973 Don't fail if ENV or BASH_ENV is readonly.
6974 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
6975 etc. are read only. Problem reported by Ludovic Courtes.
6977 2004-06-23 Noah Misch <noah@cs.caltech.edu>
6979 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
6980 zsh, disable GLOB_SUBST to avoid backslash handling problems.
6981 (trivial change)
6983 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
6985 * doc/autoconf.texi (File System Conventions): Warn about
6986 names like "aux". Problem reported by Eric Blake.
6988 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
6989 by zero instead of array size, so that we can use any arithmetic
6990 constant expression (instead of requiring an integer constant
6991 expression). This allows us to test expressions like DBL_MAX <
6992 LDBL_MAX, which didn't conform to the C standard using the old
6993 method.
6994 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
6995 now that we can do floating-point tests at compile time.
6997 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
6999 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
7000 and LDBL_EPSILON, as the resulting expression isn't an
7001 integer constant expression and violates the C standard.
7002 Problem reported by Nelson H. F. Beebe. Also, check
7003 for "L" suffix, and check that long double doesn't have
7004 worse range or precision than double, that mixed-mode
7005 arithmetic doesn't generate a diagnostic, that double
7006 constants fit in long double.
7008 2004-06-03 Kevin Ryde <user42@zip.com.au>
7010 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
7011 malloc(0) and realloc(NULL,size).
7013 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
7014 Bob Proulx.
7016 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
7018 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
7019 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
7020 by Jim Meyering.
7022 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
7024 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
7025 can be rewritten using if-then-else. Suggested by Bruno Haible.
7027 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
7029 * doc/autoconf.texi (testsuite Scripts): Fix typo.
7030 Problem reported by Stepan Kasal.
7032 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
7034 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
7035 change). Patch reported by Ralf Wildenhues in
7036 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
7038 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
7039 function F exists if the compiler and linker let you compile an
7040 expression like (F != 0). Recent versions of GCC optimize away
7041 the reference to F in that case, since every function address must
7042 be nonzero, so the link succeeds even if F does not exist.
7043 Problem reported by Manu in
7044 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
7046 * doc/autoconf.texi (Systemology): Standardize on the spelling of
7047 "Unix". Many uses changed.
7048 (Limitations of Builtins): Explain better why the ! command isn't
7049 portable.
7051 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
7053 * lib/autom4te.in (Automake-preselections): Preselect
7054 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
7056 2004-05-19 Kevin Ryde <user42@zip.com.au>
7058 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
7059 referencing AC_FUNC_STRERROR_R.
7061 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
7062 note pessimistic assumption when cross compiling.
7064 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
7066 * doc/autoconf.texi (Limitations of Make): Note that BSD make
7067 (until 2004) invoked subcommands with sh -e, contra POSIX.
7068 Reported by Kevin Ryde.
7070 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
7072 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
7073 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
7074 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
7075 `test -f " /usr/bin/grep"', which _always_ failed.
7076 (AC_PROG_SED): Ditto bogus PATH fix.
7077 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
7078 requires that grep correctly supports _multiple_ `-e' options, rather
7079 than stating only that grep should accept `-e'.
7081 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
7083 Port to C99, which requires that 'exit' be declared.
7085 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
7086 to ensure that stdlib.h is included.
7087 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
7088 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
7089 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
7090 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
7091 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
7092 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
7093 when using 'exit' in a test; C99 requires that 'exit' be declared.
7095 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
7097 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
7098 now prefers 'grep' implementations that accept -e.
7099 (Limitations of Usual Tools): Describe problems of traditional
7100 egrep and fgrep with long input lines, and of traditional grep
7101 with -e.
7102 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
7103 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
7104 All callers changed. Append /usr/xpg4/bin to the PATH, for
7105 Solaris.
7106 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
7107 the user with complaints about multiple -e options.
7108 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
7109 Define it with AC_PROG_GREP.
7110 * configure.ac (AC_PROG_GREP): Add.
7111 * lib/freeze.mk (GREP): New macro.
7113 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
7115 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
7116 a possible candidate only after all others fail, rather than
7117 consulting it first. This improves backward compatibility by
7118 better reflecting the way shell selection occurred in previous
7119 versions of Autoconf, and should help to avoid triggering latent
7120 problems in other packages, such as the one in Automake where zsh
7121 is not handled robustly:
7122 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
7123 Although it is not Autoconf's responsibility to work around
7124 problems in Automake, it nevertheless makes sense to avoid
7125 introducing unnecessary incompatibilites.
7127 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
7128 Gary V. Vaughan <gary@gnu.org>
7130 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
7131 how deeply nested we are when a suitable tool is found, set the
7132 ac_path_TOOL_found flag.
7133 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
7134 nested we are in this macro. Break out of all 3 nested loops if
7135 ac_path_TOOL_found is set.
7137 2004-04-21 Gary V. Vaughan <gary@gnu.org>
7139 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
7140 of the _AS_PATH_WALK loop too if GNU flavor is found.
7142 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
7144 * doc/autoconf.texi (Limitations of Make): Update documentation
7145 for `$<'. New entry `Long lines', based on a report from Simon
7146 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
7147 paragraph about DJGPP, based on a mail from Richard Dawe.
7149 2004-04-20 Paul Eggert <eggert@twinsun.com>
7151 * tests/c.at (C keywords): Don't assume that GCC supports
7152 "restrict" and "inline", as sufficiently-old GCC versions do not
7153 (also, GCC configured to be in pedantic C89 mode does not).
7154 Problem reported by Sumit Pandya in:
7155 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
7157 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
7158 consider -g to work if it generates warnings when plain compiles
7159 don't. Problem reported by Braden McDaniel in:
7160 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
7162 * doc/autoconf.texi (Slashes): New section, to document a problem
7163 reported by Jim Meyering in:
7164 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
7166 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
7167 linker output files before linking, to work around IRIX 6 linker bug.
7168 Problem reported by Rainer Orth in:
7169 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
7171 2004-04-20 Gary V. Vaughan <gary@gnu.org>
7173 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
7174 best tool so far counter rely on the tool path variable name to
7175 avoid checks for one tool being affected by the results of running
7176 the length check on a previous tool.
7178 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
7179 match expression argument, as different greps have different
7180 regular expression flavours.
7181 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
7182 literals.
7183 (AC_PROG_EGREP): Pass 'EGREP$'.
7184 (AC_PROG_GREP): Pass 'GREP$'.
7186 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
7188 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
7189 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
7191 2004-03-29 Paul Eggert <eggert@twinsun.com>
7193 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
7194 Types, Specific Compiler Characteristics, System Services,
7195 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
7196 etc. consistently instead of 'long', 'short', 'unsigned' etc.
7197 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
7198 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
7199 Likewise.
7200 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
7201 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
7202 AC_TYPE_OFF_T): Likewise.
7203 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
7204 Likewise.
7206 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
7207 pacify libtool 1.5.2. Fix quoting problems in sed command.
7209 2004-03-28 Paul Eggert <eggert@twinsun.com>
7211 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
7212 now defines HAVE_DECL_TZNAME if it is declared, when
7213 HAVE_STRUCT_TM_TM_ZONE is not defined.
7214 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
7215 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
7216 for HAVE_TZNAME.
7218 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
7220 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
7221 superfluous backslashing of quotes (") in sed expressions;
7222 thanks to Paul Eggert.
7224 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
7226 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
7227 Fortran compiler is ifort, also added pghpf; thanks to Nelson
7228 H. F. Beebe for the bug report.
7230 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
7232 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
7233 quoted -cmdline argument in Portland Group compiler (bug
7234 reported by Jeffrey J. Barteet).
7236 2004-03-25 Kevin Ryde <user42@zip.com.au>
7238 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
7239 (Run Time): ... here, where it's now mentioned.
7241 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
7243 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
7244 inherits from language Autoconf-without-aclocal-m4.
7245 (Customizing autom4te): Adjust example; the cache must now be
7246 disabled for language Autoconf-without-aclocal-m4.
7248 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
7249 Nathanael Nerode <neroden@twcny.rr.com>
7251 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
7252 AC_CHECK_TOOLS): Warn if a cross-tool is found without
7253 a prefix.
7254 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
7255 AC_CHECK_TARGET_TOOLS): New macros.
7256 * doc/autoconf.texi (Generic Programs): Document
7257 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
7258 AC_CHECK_TARGET_TOOLS, and warn for future changes
7259 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
7260 AC_CHECK_TOOLS.
7261 (Specifying Names): Document the reason for these future
7262 behavioral changes.
7263 * tests/mktests.sh: Do not generate tests for the
7264 new macros.
7265 * NEWS: Document these changes.
7267 * doc/autoconf.texi: Avoid macros with unbraced arguments,
7268 they make TeX hang up.
7270 2004-03-15 Paul Eggert <eggert@bogus.example.com>
7272 * NEWS: New macro AC_CHECK_ALIGNOF.
7273 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
7274 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
7275 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
7276 vowel.
7277 (AC_CHECK_ALIGNOF): New macro.
7278 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
7279 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
7280 those for sizeof.
7282 2004-03-03 Paul Eggert <eggert@twinsun.com>
7284 * bin/Makefile.am (edit): Don't use $< in a context where
7285 POSIX doesn't require support for it. Use $@.in instead.
7286 Problem reported by Anthony N. Frasso in
7287 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
7288 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
7290 2004-02-23 Gary V. Vaughan <gary@gnu.org>
7292 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
7293 from the next generation of Libtool.
7294 * lib/autom4te.in (Autoreconf-preselections): Ditto.
7296 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7298 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
7299 is not always thread-safe. Report from Nathanael Nerode.
7301 2004-02-18 Paul Eggert <eggert@twinsun.com>
7303 Fix a dependencies problem, stemming from a Autoconf 2.59 build
7304 problem on QNX reported by Stephen Rasku in
7305 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
7307 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
7308 $(m4sh_m4f_dependencies); this removes a FIXME.
7309 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
7310 (MAINTAINERCLEANFILES): Split into pieces,
7311 one per related section. Add $(srcdir)/wrapper.in.
7313 2004-02-09 Paul Eggert <eggert@twinsun.com>
7315 * doc/autoconf.texi (Setting Output Variables): Emphasize that
7316 AC_SUBST provides no portable way to escape literal newlines.
7318 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
7319 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
7320 Darwin uses -lcrt2.o and there's little point to cataloging all
7321 the system variants. Partial fix reported by Andreas Waechter in:
7322 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
7323 for bug reported by Nelson H. F. Beebe in:
7324 http://mail.gnu.org/archive/html/bug-autoconf/2003-12/msg00090.html
7326 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
7328 * doc/autoconf.texi (AU_DEFUN): Fix English,
7329 suggested by Paul Eggert.
7330 * lib/autoconf/autoupdate.m4: Correct reference to
7331 acobsolete.m4, suggested by Alexandre Duret-Lutz.
7333 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
7335 * bin/autoupdate.in: Define __file__ so that warnings
7336 refer to the correct file.
7337 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
7338 the behavior of the third argument.
7339 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
7340 correctly the behavior of the third argument. Document
7341 what the three macros that AU_DEFUN defines do. Fix
7342 warning message when the third argument includes $0
7343 (reported by Alexandre Duret-Lutz).
7345 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
7346 Eric Sunshine <sunshine@sunshineco.com>
7347 Paul Eggert <eggert@twinsun.com>
7349 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
7350 (AS_INIT): Output shell initialization there. Removed optional
7351 parameter. Expand _AS_SHELL_FN_SPY.
7352 (AS_INIT_WITH_SHELL_FN): Removed.
7353 (_AS_SHELL_FN_SPY): New macro.
7354 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
7355 macros.
7356 (AS_SHELL_SANITIZE): Remove loop to find better shell
7357 and documentation for the parameter.
7358 (_AS_DETECT_BETTER_SHELL): Move it here.
7359 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
7360 (_AS_RUN): Move it here, support testing with eval.
7361 (AS_REQUIRE_SHELL_FN): Require shell functions when
7362 it is used.
7363 (_AS_LINENO_WORKS): Put around braces, we do not
7364 trigger the bash bug anymore.
7365 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
7366 use AS_INIT_WITH_SHELL_FN.
7367 * bin/autoconf.in, tests/wrapper.in: Regenerated.
7369 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
7371 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
7372 * doc/autoconf.texi: Don't say that the third parameter
7373 is broken.
7374 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
7375 (AU_DEFUN): Honor the third parameter, create autoupdate
7376 macros with AU_DEFINE.
7377 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
7378 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
7379 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
7380 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
7381 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,
7382 AC_ARG_ARRAY, AC_CYGWIN, AC_EMXOS2, AC_MINGW32,
7383 AC_XENIX_DIR): Likewise.
7384 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS,
7385 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
7386 * lib/autoconf/status.m4: Remove FIXME.
7387 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
7388 that the macro is not present anymore in the updated
7389 configure.ac.
7390 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
7391 of autoupdate.
7393 2004-01-28 Paul Eggert <eggert@twinsun.com>
7395 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
7396 copyright years.
7397 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
7398 2003 (except 1997) to the list of copyright years. This undoes
7399 the 2003-05-22 change, which removed the older years from the list.
7400 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
7402 2004-01-27 Gary V. Vaughan <gary@gnu.org>
7403 Albert Chin-A-Young <china@thewrittenword.com>
7405 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
7406 grep or ggrep program in PATH that accepts as long lines as
7407 possible.
7408 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
7409 AC_PROG_GREP.
7410 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
7411 egrep and fgrep respectively if $GREP -E/-F don't work.
7412 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
7413 _AC_PROG_GREP, and AC_PROG_SED.
7414 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
7415 longest input length accepted by a command.
7416 (AC_PROG_SED): Use it.
7417 * doc/autoconf.texi (Particular Programs): Document the changes.
7418 * NEWS: Updated.
7420 2004-01-27 Paul Eggert <eggert@twinsun.com>
7422 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
7423 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
7424 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
7425 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
7427 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
7428 bin/autoconf.in, config/Makefile.in, config/config.guess,
7429 config/config.sub, config/install-sh, config/mdate-sh,

7440 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
7441 tests/actypes.at: Regenerate and/or sync with original
7442 sources.
7444 2004-01-26 Paul Eggert <eggert@twinsun.com>
7446 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
7447 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
7448 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
7449 not <inttypes.h>. Problem reported by Tim Mooney in
7450 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
7451 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
7452 Likewise.
7454 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
7455 otherwise "make check" fails because it forbids cmp (I guess
7456 because cmp treats files as binary on DOS-like systems).
7458 * tests/mktests.sh: Update copyright date to 2004, since some tests
7459 have changed in 2004.
7461 2004-01-23 Gary V. Vaughan <gary@gnu.org>
7463 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
7464 non-truncating sed or gsed program in PATH.
7465 * tests/acprograms.at: Add it.
7466 * doc/autoconf.texi (Particular Programs): Document it.
7467 * NEWS: Updated.
7469 2004-01-15 Paul Eggert <eggert@twinsun.com>
7471 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
7472 -std1 disables some useful extensions on Tru64. Problem reported
7473 by N. Lichtmaier in
7474 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
7476 2004-01-14 Paul Eggert <eggert@twinsun.com>
7478 * doc/autoconf.texi (Programming in M4sh): Document that
7479 AS_MKDIR_P succeeds if the destination is a symbolic link
7480 to an existing directory.
7481 (Limitations of Usual Tools): Note that mkdir -p might not
7482 succeed on symlinks to directories.
7484 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
7486 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
7487 * bin/autoheader.in: Grammar fix in message.
7488 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
7489 Test for dir before calling mkdir -p. (trivial changes)
7491 2004-01-13 Eric Blake <ebb9@byu.net>
7493 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
7494 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
7496 2004-01-10 Jim Meyering <jim@meyering.net>
7498 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
7500 2004-01-09 Paul Eggert <eggert@twinsun.com>
7502 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
7503 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
7504 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
7505 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
7506 AC_COMPILE_IFELSE, since we now assume our caller invokes
7507 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
7508 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
7509 of AC_RUN_IFELSE; this avoids the warning mentioned above.
7510 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
7512 2004-01-07 Paul Eggert <eggert@twinsun.com>
7514 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
7515 `"'...'"`, as it's confusing (and I suspect it may not work on
7516 some platforms). The code was incorrect anyway, as it assumed
7517 that \$ evaluated to itself in that context. Reported by
7518 Alexandre Duret-Lutz.
7520 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
7522 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
7523 and _LT_AC_TAGCONFIG.
7525 2004-01-06 Paul Eggert <eggert@twinsun.com>
7527 * doc/autoconf.texi (One Macro Call): Fix an incorrect
7528 example, and add more examples. Reported by Eric Sunshine.
7530 2004-01-05 Paul Eggert <eggert@twinsun.com>
7532 * doc/autoconf.texi (Limitations of Usual Tools):
7533 Remove warning against "rm -fr" introduced yesterday; it
7534 was a false alarm.
7536 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
7537 autoscan, autoupdate, ifnames): Don't use chmod -w.
7538 * lib/Makefile.am (autom4te.cfg): Likewise.
7539 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
7540 "chmod -w".
7542 2004-01-04 Paul Eggert <eggert@twinsun.com>
7543 Paolo Bonzini <bonzini@gnu.org>
7545 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
7546 by doing lineno substitution only on lines containing "$LINENO".
7548 2004-01-04 Paul Eggert <eggert@twinsun.com>
7550 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
7551 Use "rm -f" to remove conftest.sed, not plain "rm".
7552 Bug reported by David Relson in
7553 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
7555 * Makefile.am (autom4te-update):
7556 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
7557 * Makefile.maint (my-distcheck, do-po-update): Likewise.
7558 * doc/autoconf.texi (Guidelines): Likewise.
7559 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

7564 * tests/Makefile.am (clean-local): Likewise.
7565 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
7566 srcdir): Likewise.
7567 * doc/autoconf.texi (Limitations of Usual Tools):
7568 Warn against "rm -fr".
7570 2004-01-03 Paul Eggert <eggert@twinsun.com>
7572 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
7573 -c -o might not work. From a suggestion by Kevin Ryde.
7574 (C Compiler, Generating Sources, Limitations
7575 of Usual Tools, Limitations of Make, Making testsuite Scripts):
7576 Don't put '-o' after non-options, as POSIX doesn't allow this.
7577 Mention that cc's name might be gcc or c89 or whatever.
7579 2004-01-04 Kevin Ryde <user42@zip.com.au>
7581 * doc/autoconf.texi: Add various further index entries.
7583 2003-12-29 Paul Eggert <eggert@twinsun.com>
7585 * bin/autoreconf.in (autoreconf_current_directory):
7586 Fix typo: mkdir without umask arg.
7588 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
7590 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
7591 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
7592 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
7593 explanation clearer.
7595 2003-12-24 Andreas Schwab <schwab@suse.de>
7597 * doc/autoconf.texi (Default Includes): Fix misspelling of
7598 AC_INCLUDES_DEFAULT.
7600 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
7602 * configure.ac: Test if sh -n works.
7603 * configure: Regenerate.
7604 * tests/atlocal.in: Store the result here.
7605 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
7606 tools.at, looking in atlocal's ac_cv_sh_n_works instead
7607 of explicitly testing.
7608 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
7609 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
7610 * tests/tools.at (Syntax of the shell scripts): Simplify
7611 using AT_CHECK_SHELL_SYNTAX.
7612 (Syntax of the Perl scripts): Remove definition of
7613 AT_CHECK_PERL_SYNTAX.
7615 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
7617 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
7618 stderr to /dev/null.
7619 * bin/autoconf.in: Regenerate.
7620 * bin/wrapper.in: Regenerate.
7622 2003-11-26 Paolo Bonzini <bonzini@gnu.org>
7624 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
7625 Extracted from AS_SHELL_SANITIZE.
7626 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
7627 macros.
7628 (AS_SHELL_SANITIZE): Move reinvocation code from
7629 _AS_LINENO_WORKS, use it to find out if shell
7630 functions work.
7631 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
7632 does not work.
7633 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
7634 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN
7635 was called.

7645 (&sizes): New.
7646 Use them.

7648 them on the fly.
7650 2003-11-24 Akim Demaille <akim@epita.fr>
7652 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

7680 parameter of AU_DEFUN.
7681 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.
7682 (AU_DEFUN): Remove the third parameter, it was not used.
7683 Use AC_DEFUN directly, not AU_DEFINE.

7685 the expanded body, consistently with other macros such as AC_USG.
7687 2003-11-17 Paul Eggert <eggert@twinsun.com>
7689 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
7690 into the initial confdefs.h, to work around a bug in NextStep 3.3
7691 patch 3 reported by Eric Sunshine.
7693 2003-11-15 Kevin Ryde <user42@zip.com.au>
7695 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
7696 than $target since the latter is not usual, add guidelines on when to
7697 use or not use the system type.
7699 2003-11-12 Derek Price <derek@ximbiot.com>
7701 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
7702 typo misrepaired by an auto-spellcheck.
7704 2003-11-12 Akim Demaille <akim@epita.fr>

7707 --force-missing unless it actually supports it.
7708 From Debian #219336.
7710 2003-11-12 Akim Demaille <akim@epita.fr>

7778 2003-10-28 Akim Demaille <akim@epita.fr>
7780 * Makefile.cfg (local_updates, executable-update): Tweak to be

7854 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
7856 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
7857 cross test.
7859 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
7861 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
7862 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

7873 Issue a more-informative diagnostic.
7874 Problems reported by Eric Sunshine.
7876 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
7878 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
7879 -mGLOB_options_string stuff for Intel ifc, which can cause

7889 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
7890 that future autopoint/aclocal/automake/autoreconf will be able

7899 -lcrt[01].o.
7901 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
7903 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
7904 cache variable instead of $G77 to decide whether to include -O2,
7905 since $G77 is specific to Fortran 77.
7907 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7909 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
7910 free" flag. Re-order flags tested into rough order of popularity.
7912 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7914 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
7915 arguments so that it can be used with syntax identical to
7916 AC_PROG_F77, and so that we can more easily decide to
7917 remove/deprecate the DIALECT optional argument in the future if it
7918 proves troublesome.
7919 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
7920 non-freeform-supporting compilers. Document freeform flags.
7922 2003-10-03 Akim Demaille <akim@epita.fr>
7924 * configure.ac: Look for emacs, not macs.
7925 Reported by Eric Sunshine.
7927 2003-10-03 Akim Demaille <akim@epita.fr>
7929 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
7930 * bin/autoreconf.in (autoreconf_current_directory): Create the

7934 2003-10-03 Akim Demaille <akim@epita.fr>
7936 * configure.ac: Quotation and formatting changes.

7958 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
7959 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
7961 2003-09-30 Akim Demaille <akim@epita.fr>
7963 * config/announce-gen (&print_news_deltas): Extracted from...
7964 (&print_changelog_deltas): here.
7965 (&news_file): Rename as...
7966 (@news_file): this.

7983 Problem reported by Lars J. Aas in
7984 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
7985 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
7986 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
7987 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
7989 2003-09-26 Akim Demaille <akim@epita.fr>
7991 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
7992 directory for AC_CONFIG_COMMANDS' first argument exists.
7993 This makes valid the invocation of _AC_SRCPATH that follows.
7994 Reported by Eric Sunshine.
7995 * doc/autoconf.texi (Configuration Commands): Adjust.
7997 2003-09-26 Akim Demaille <akim@epita.fr>
7999 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
8000 Reported by Ralf Corsepius.
8002 2003-09-26 Akim Demaille <akim@epita.fr>
8004 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
8005 arguments.
8006 Actually, use AU_ALIAS.
8007 From Bruno Haible.
8009 2003-09-26 Paul Eggert <eggert@twinsun.com>
8011 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
8012 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
8013 Problem reported by Eric Sunshine in:

8016 2003-09-26 Akim Demaille <akim@epita.fr>
8018 The test suite are sometimes assigning timings incorrectly.
8019 Reported by Henk Krus.
8020 Diagnosed by Nicolas Joly.
8022 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
8023 AT_help_all.
8024 Instead of making AT_help a sequence of assignments to grow
8025 $at_help_all, just make AT_help_all be the growing contents of
8026 $at_help_all, and make a single assignment in...
8027 (AT_INIT): here.
8028 (at_times_skip): Flip the meaning and rename as...
8029 (at_times_p): this.
8030 (AT_INIT): When summarizing the test that ran, remove
8031 $at_times_file after use, and check it is present before trying to
8032 use it.
8034 2003-09-25 Akim Demaille <akim@epita.fr>
8036 Version 2.57d.
8038 * bin/Makefile.am (edit): Handle '@configure_input@'.
8039 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
8040 (ifnames): chmod -w.
8041 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
8042 executables, not bin/ executables! Otherwise all the magic needed
8043 to find non installed files is turned off. This caused a failure
8044 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
8045 as found in its environment (sent by tests/autoreconf): pointing
8046 to bin/autom4te that could not find its files.
8047 * tests/mktests.sh: Force the replacement of generated files, for
8048 the sake of "mv" program that are interactive when overwriting a
8049 -w file.
8050 * config/install-sh: Upgrade from CVS Automake.
8052 2003-09-23 Paul Eggert <eggert@twinsun.com>
8054 * doc/autoconf.texi (Limitations of Builtins): Document test -h
8055 versus test -L issues.
8057 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
8058 Paul Eggert <eggert@twinsun.com>
8060 Trivial change to support GCC's configuration procedure.
8061 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
8062 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
8063 about inconsistency if the preprocessor is set to give errors for
8064 any warning.
8065 * doc/autoconf.texi (C Compiler Characteristics): Document this.
8067 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
8069 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
8070 and XFile.pm from Automake.

8083 2003-09-12 Akim Demaille <akim@epita.fr>
8085 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
8086 not asm/types.h.
8088 2003-09-11 Akim Demaille <akim@epita.fr>
8090 * doc/autoconf.texi (Header Portability): linux/random.h.
8091 From Peter Hendrickson.
8093 2003-09-10 Akim Demaille <akim@epita.fr>
8095 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
8096 willing to edit the output files.
8098 2003-09-10 Akim Demaille <akim@epita.fr>
8100 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
8101 and AC_FC_FREEFORM.
8102 * tests/mktests.sh: Skip AC_FC_SRCEXT.
8103 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
8105 2003-09-09 Akim Demaille <akim@epita.fr>

8118 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
8119 Improve the accuracy of the wording about obsolescence.
8120 From a suggestion by Ian Lance Taylor in
8121 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
8123 2003-09-05 Paul Eggert <eggert@twinsun.com>
8125 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
8126 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
8128 2003-09-04 Akim Demaille <akim@epita.fr>
8130 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
8131 AC_FUNC_WAIT3.
8133 2003-09-04 Akim Demaille <akim@epita.fr>
8135 * bin/autom4te.in: Use &fatal where more appropriate than &error.
8136 (freeze): When exiting, use $exit_code.

8143 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
8145 Add support for newer Fortran dialects. The F77 interface is
8146 unchanged, and continues to support Fortran 77. New FC macros
8147 correspond to all the old F77 macros, with output variables FC,
8148 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
8149 available dialect, but older dialects can be specified. There are
8150 new macros AC_FC_SRCEXT to set the source extension, and
8151 AC_FC_FREEFORM to accept free-form source files.
8153 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
8154 New macros.
8155 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

8171 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
8172 Rewrite in terms of the above.
8173 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
8174 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

8178 2003-09-02 Paul Eggert <eggert@twinsun.com>
8180 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
8181 Document problems with timestamp resolution that 'make', 'cp -p', and
8182 'touch -r' have.
8184 2003-08-27 Akim Demaille <akim@epita.fr>
8186 * tests/m4sugar.at (cross_warning): Make sure to enable the
8187 output, so that we can track spurious m4sugar output.
8188 * tests/local.at: Require 2.57.
8189 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
8190 are defaulted by AT_CHECK anyway.
8191 Use AT_CHECK_AUTOM4TE.
8192 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
8193 missing dnl.
8195 2003-08-27 Akim Demaille <akim@epita.fr>
8197 * bin/autoheader.in: Issue the "Using auxiliary..." message only
8198 when -Wobsolete is set.
8199 Set it on by default.
8200 Suggested by Klee Dienes.
8202 2003-08-27 Akim Demaille <akim@epita.fr>
8204 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
8205 documentation.
8206 From Guido Draheim.
8208 2003-08-26 Akim Demaille <akim@epita.fr>
8210 * doc/autoconf.texi (Output): Make clear that one can run code
8211 after AC_OUTPUT.
8213 2003-08-25 Akim Demaille <akim@epita.fr>
8215 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
8216 CVS Bison.
8218 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
8220 * bin/autoreconf.in (parse_args): Do not pass --no-force to
8221 Automake versions prior to 1.8.
8223 2003-08-25 Akim Demaille <akim@epita.fr>
8225 * doc/autoconf.texi (Header Portability): netinet/if_ether.h.

8230 * configure.ac: Bump to 2.57c.
8232 2003-08-22 Akim Demaille <akim@epita.fr>
8234 Version 2.57b.
8236 * Makefile.cfg (local-checks-to-skip): New.
8237 * Makefile.maint (local-check): Rename as...
8238 (local-checks-available): this.
8239 (local-check): New.
8241 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
8242 * configure.ac: Require Automake 1.7.6.
8244 2003-08-22 Akim Demaille <akim@epita.fr>
8246 Output stack traces in warnings.
8248 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
8249 Replace the former...
8250 (m4_warn): Pass the call stack to _m4_warn.
8251 * bin/autom4te.in: Adjust to output the call stack.
8252 * tests/m4sugar.at (m4@&t@_warn): Adjust.
8254 2003-08-22 Akim Demaille <akim@epita.fr>
8256 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
8257 * bin/autom4te.in: Adjust.
8259 2003-08-21 Akim Demaille <akim@epita.fr>
8261 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
8262 (&verbose): Remove.
8263 (&getopt): Adjust the note and verb channels, depending upon
8264 --verbose.
8265 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
8266 * bin/autoupdate.in: Adjust.
8267 Use &verb, not &verbose.
8269 2003-08-21 Akim Demaille <akim@epita.fr>
8271 * bin/autoheader.in (&parse_args): Use &parse_warnings and
8272 &parse_WARNINGS.
8273 ($help): Use Autom4te::ChannelDefs::usage.
8274 * bin/autoscan.in: Use Autom4te::ChannelDefs.
8275 * lib/Autom4te/General.pm: Don't export error: you don't own it.
8277 2003-08-21 Akim Demaille <akim@epita.fr>
8279 First stab at preserving warnings between calls to autom4te,
8280 including when the cache is used.
8282 There are still several issues: (i) there are too many runs of m4
8283 (one for include, one for warnings, and some more), (ii) warnings
8284 spreading on several lines are not handled gracefully, (iii) the
8285 code meant to have the call stack display for errors does not work
8286 (its handling should move from m4 to autom4te).
8288 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
8289 Use them.
8290 (@preselect): Add m4_warn.
8291 ($exit_status): Remove, use $exit_code.
8292 ($help): Use Autom4te::ChannelDefs::usage.
8293 (&handle_m4): No longer define the m4_warnings.
8294 At each run, extract and report the warnings.
8295 Always cache the result, including if the exit status is on
8296 failure, since if nothing changes, we should result in the same
8297 failure, hence we can use the cache.
8298 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
8299 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
8300 Remove.
8301 (m4_warn): Redefine as a do-nothing: it is its invocation that
8302 matters, as warnings are now reported via traces.
8303 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
8304 the contents of m4_warn: make it _call_ m4_warn, so that tracing
8305 the latter reveals calls to the former.
8307 Adjust the tests.
8309 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
8311 2003-08-21 Akim Demaille <akim@epita.fr>
8313 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
8314 Use them.
8316 2003-08-21 Akim Demaille <akim@epita.fr>
8318 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
8319 forward order.
8320 * lib/Autom4te/ChannelDefs.pm: Doc typos.
8321 (&parse_warnings): Accept a list of warning requests.
8322 (&usage): Return a string, not a side effect.
8323 (cross): New warning category.
8325 2003-08-21 Akim Demaille <akim@epita.fr>
8327 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
8328 (&require_configure_ac): Accept an optional directory argument.
8329 ($configure_ac): Remove.
8330 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
8331 (&catfile): Remove.
8332 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
8333 * bin/autoscan.in: Adjust.
8335 2003-08-20 Akim Demaille <akim@epita.fr>
8337 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
8338 Reported by Alexandre Duret-Lutz.
8340 2003-08-20 Akim Demaille <akim@epita.fr>
8342 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
8343 * bin/autom4te: Adjust.
8344 In particular, be Autoconf tools are really silent when properly
8345 working, bind the verbosity of the 'note' channel to $verbose.
8346 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
8347 (&xsystem, &contents): Remove, since they are exported by...
8348 * lib/Autom4te/FileUtils.pm: this.
8349 More perldoc.
8350 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
8351 * lib/Autom4te/FileUtils.pm: here.
8353 2003-08-20 Akim Demaille <akim@epita.fr>
8355 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
8356 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
8357 from CVS Automake.
8359 2003-08-20 Akim Demaille <akim@epita.fr>
8361 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
8362 (autom4te-update): New.
8363 * Makefile.cfg (update): Bind autom4te-update.
8365 2003-08-19 Derek Price <derek@ximbiot.com>
8367 * lib/autotest/general.m4: Comment various HELP_* diversions.
8368 (PARSE_ARGS_BEGIN): New section for option parsing related
8369 initialization.
8370 (AT_ARG_OPTION,AT_ARG_OPTION_ARG,_AT_ARG_OPTION): New macros to define
8371 package specific options and associated help.
8373 2003-08-19 Akim Demaille <akim@epita.fr>
8375 * config/announce-gen, Makefile.cfg: New.
8376 * Makefile.am: Adjust.
8377 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
8379 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
8381 * lib/autom4te.in (Automake-preselections): Preselect
8382 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
8383 and m4_sinclude.
8385 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
8387 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
8388 (Autoconf-without-aclocal-m4): ... this new language.
8389 * doc/autoconf.texi (autom4te Invocation): Mention
8390 Autoconf-without-aclocal-m4.

8394 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
8395 RUN-IF-PASS optional arguments.
8397 2003-08-18 Derek Price <derek@ximbiot.com>

8404 STDOUT & STDERR arguments.
8406 2003-08-14 Derek Price <derek@ximbiot.com>
8408 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
8409 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
8410 shorter column three. Add DESCRIPTION to log file content.
8412 2003-08-13 Derek Price <derek@ximbiot.com>
8414 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
8415 output.
8417 2003-08-12 Derek Price <derek@ximbiot.com>
8419 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
8420 (AT_CHECK_NOESCAPE): Move core functionality to...
8421 (_AT_CHECK): ...this new macro.
8423 2003-08-07 Derek Price <derek@ximbiot.com>
8425 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
8426 (AT_CHECK_NOESCAPE): ...to this new macro.
8428 2003-07-31 Paul Eggert <eggert@twinsun.com>
8430 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
8431 in Bash 2.01. Problem reported by Brian Gough in
8432 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
8434 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
8436 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
8437 -lcrt1.o, for OS X. (trivial change)
8439 2003-07-07 Paul Eggert <eggert@twinsun.com>
8441 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
8442 inside '#ifndef __cplusplus'. Problem reported by
8443 Bob Friesenhahn.
8445 2003-07-06 Bill Clarke <llib@computer.org>
8447 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
8448 'long', not 'int', for benefit of Sun's recent C++ compilers
8449 (trivial change). See:
8450 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
8451 (This really should be 'intptr_t', not 'long', but that would
8452 take more work.)
8454 2003-06-25 Akim Demaille <akim@epita.fr>
8456 * lib/Makefile.am (autom4te.cfg): Make it read only.
8457 Depend on Makefile since it contains substitutions.
8458 From Paolo Bonzini.
8459 * lib/autom4te.in (args): Add local.at? for Autotest args.
8460 This change was made on autom4te.cfg which is generated.
8461 Reported by Raja R. Harinath.
8463 2003-06-25 Akim Demaille <akim@epita.fr>
8465 * doc/autoconf.texi (Header Portability): sys/mount.h.
8466 From Gareth McCaughan.
8468 2003-06-23 Akim Demaille <akim@epita.fr>
8470 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
8471 not all of them. This fixes 1. the fact that when testing
8472 Autoconf there are many many config.log, 2. the incorrect use of
8473 top_srcdir to find config.log.
8474 Don't mix the detailed output of failed test with the summary of
8475 failures. Rather, append detailed log afterwards.
8477 2003-06-23 Akim Demaille <akim@epita.fr>
8479 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
8480 always run: output config.log on $at_group_log.
8482 2003-06-23 Akim Demaille <akim@epita.fr>
8484 * tests/torture.at (#define header templates): Don't use quotes in
8485 C++ comments as it puzzles Emacs' sh font-lock-mode.
8487 2003-06-23 Akim Demaille <akim@epita.fr>
8489 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
8490 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
8491 * tests/atspecific.m4: Rename as...
8492 * tests/local.at: This.
8493 * tests/suite.at: Move the globals into...
8494 * tests/local.at: here.
8495 * tests/Makefile.am: Adjust.
8496 * doc/autoconf.texi (testsuite Scripts): Adjust.
8498 2003-06-21 Kevin Ryde <user42@zip.com.au>
8500 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
8501 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
8502 ensuring we add -std1 for full-ANSI.
8504 * doc/autoconf.texi (hdrindex): New macro.
8505 Add index entries for portability of various standard header files.
8507 2003-06-20 Akim Demaille <akim@epita.fr>
8509 * configure.ac: Bump to 2.57b.
8511 2003-06-20 Akim Demaille <akim@epita.fr>
8513 Version 2.57a.
8515 2003-06-20 Akim Demaille <akim@epita.fr>
8517 * bin/autom4te.in: Don't rely on $HOME being defined.
8518 Reported by Marc Espie as PR/233.
8520 2003-06-20 Akim Demaille <akim@epita.fr>
8522 * lib/autotest/general.m4: Use at_times_file only if used.
8523 From Nicolas Joly.
8525 2003-06-20 Akim Demaille <akim@epita.fr>
8527 * config/config.guess, config/config.sub, config/elisp-comp,
8528 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
8529 Update from masters.
8531 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
8533 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
8534 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
8535 (TEST_SCRIPT): New diversion.
8536 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
8537 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
8538 (AT_INIT): Support for expected failures.
8540 2003-06-02 Akim Demaille <akim@epita.fr>
8542 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
8543 changes.
8544 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
8545 Autoconf nor Automake.
8546 (&contents): New, from Automake.
8547 PODify.
8549 2003-05-28 Paul Eggert <eggert@twinsun.com>
8551 * NEWS, doc/autoconf.texi (Particular Functions),
8552 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
8553 is the inverse of localtime.
8555 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
8557 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
8558 (handle_exec_errors): New function. Work around $! being
8559 altered by WEXITSTATUS.
8560 (xqx, xsystem): Use handle_exec_errors.
8562 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
8564 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
8565 Do not call `_exit()', simply modify `$?'.
8566 (xsystem): Reset $! before running system, and check it afterward.
8567 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
8568 63 for version mismatches.
8570 2003-05-23 Akim Demaille <akim@epita.fr>
8572 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
8573 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
8574 the middle of a line).
8575 * lib/m4sugar/m4sugar.m4: Likewise.
8576 Remove useless spaces in comments.
8578 2003-05-23 Akim Demaille <akim@epita.fr>
8580 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
8581 exit 63, so that we (or Automake's "missing") can tell the
8582 difference with a plain failure.
8583 * doc/autoconf.texi (Notices): Adjust.
8585 2003-05-23 Akim Demaille <akim@epita.fr>
8587 * Makefile.am, bin/Makefile.am, config/Makefile.am,
8588 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
8589 White spaces cleanup.
8591 2003-05-22 Jim Meyering <jim@meyering.net>
8592 Paul Eggert <eggert@twinsun.com>
8594 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
8595 Remove `#include <stdlib.h>' from the list; we should never
8596 make confdefs.h include <stdlib.h> or <cstdlib>, because the
8597 resulting namespace pollution would cause other tests to fail.
8598 Configure scripts run with some older versions of g++ and HP's
8599 aCC would fail due to such an #include. Problems reported by
8600 Matthew Mueller in <http://bugs.debian.org/120704> and by
8601 Keith Bostic in
8602 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
8603 In the test, use the test declaration before including <stdlib.h>,
8604 as that's closer to how it'll be used.
8606 2003-05-23 Akim Demaille <akim@epita.fr>
8608 * doc/autoconf.texi (Header Portability): ucred.h.
8609 From Ian Redfern.
8611 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8613 Overhaul Autotest's logging: generate separate log files
8614 in testsuite.dir/NNN/testsuite.log, and append them to
8615 testsuite.log instead of re-running the test verbosely.
8617 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
8618 file descriptor, write 0 to at_status_file instead of setting
8619 at_status=0, initialize some new variables (at_status_file,
8620 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
8621 to rerun the tests, instead append the at_group_log to the
8622 at_suite_log when a test fails.
8623 (AT_SETUP): pipe the test case's output into at_tee_pipe,
8624 with the AS_MESSAGE_LOG_FD redirected to stdout.
8625 (AT_CLEANUP): save the output status in $at_status_file
8626 and restore it, redirect the AS_MESSAGE_LOG_FD back to
8627 its original place.
8628 (AT_CHECK): since tests are run with a redirected stdout,
8629 and used to be re-run in verbose mode, turn some $at_verbose
8630 into echo, and don't redirect the output of testing stdout
8631 and stderr.
8633 * lib/autotest/autoconf.texi (testsuite Scripts): Update
8634 the name of the debugging directory and information about
8635 its contents.
8637 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8639 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
8640 parameter.

8669 Reported by Jim Meyering.
8671 2003-05-22 Akim Demaille <akim@epita.fr>

8752 and truncate.
8754 2003-05-06 Akim Demaille <akim@epita.fr>
8756 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
8757 longer updates aclocal.m4 if useless, (ii) if a file m4_included
8758 by aclocal.m4 is changed it might require the importing of another
8759 m4 extension file, i.e., aclocal must be run.
8761 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
8762 (&parse_args): Use --force with aclocal if required and supported.
8763 (&autoreconf_current_directory): Use &run_aclocal.

8770 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
8771 argument instead of a file name, so that the request file remains
8772 open during the whole autom4te run.
8773 ($icache_file): New.
8774 (&freeze): Lock the $icache_file.
8776 2003-04-29 Derek Price <derek@ximbiot.com>
8778 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
8779 seperator with m4_append_uniq(). It doesn't work.
8780 (AT_CLEANUP): Add `;' to end of at_help_all.
8781 (AT_INIT): Allow --keywords to be specified more than once. When
8782 grepping $at_help_all for keywords, use the field and keyword
8783 seperators to ensure a complete keyword match. Alter at_prev handling
8784 to support the new --keywords behavior.
8786 2003-04-27 Karl Berry <karl@freefriends.org>
8788 * doc/autoconf.texi: Make the dir entries in the autoconf manual
8789 align better with others. I also made some of the individual
8790 entries on one line, for brevity and to make it easier for me to
8791 sort my dir-example file in the Texinfo distribution :).

8858 header causes problems.
8860 2003-03-28 Akim Demaille <akim@epita.fr>
8862 * tests/torture.at (Configuring subdirectories): Require aclocal
8863 1.4, otherwise the test fails, as it does support configure.ac.

8868 * doc/autoconf.texi (C Compiler): `#line' portability.

8874 layout in order to allow scripting around test groups.
8876 2003-03-27 Derek Price <derek@ximbiot.com>

8888 (AC_HELP_STRING): AU_DEFUN to...
8889 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
8890 * tests/m4sh.at (AS_HELP_STRING): New test.
8892 * tests/acgeneral.at: Regenerated.
8894 2003-03-26 Derek Price <derek@ximbiot.com>
8896 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
8897 sense. Verbosify the diversion definitions comment.

8901 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to

8936 Tru64 make in the "target lookup" section.
8937 (Automake): Automake 1.5+ no longer requires special tools to be
8938 present on the developer's host.

8954 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
8955 to cope with DOS-style absolute paths, when constructing
8956 ${ac_make}.
8958 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
8959 When constructing paths with IFS=:, quote the path. If we're
8960 constructing a DOS-style absolute path, we don't want to split it
8961 on the colon.
8963 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
8964 in description.
8966 2003-02-25 Pavel Roskin <proski@gnu.org>

8978 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
8979 to fix a mismatch between example and discussion.
8981 2003-02-24 Kevin Ryde <user42@zip.com.au>
8983 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
8984 format starting with "-".
8986 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
8988 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
8989 is not portable inside Makefile.
8991 2003-02-20 Akim Demaille <akim@epita.fr>
8993 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
8994 compiler says yeah, but preproc says nope, compiler is right.
8995 Conversely, prompt the reader to send a bug report to the
8996 maintainers of the package, not of Autoconf.
8998 2003-02-20 Klee Dienes <kdienes@apple.com>
9000 * bin/autoreconf.in (autoreconf_current_directory): Properly
9001 handle an empty aclocal.m4.

9005 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Quote
9006 $ac_prefix_program.
9007 From Larry Jones.
9009 2002-12-23 Paul Eggert <eggert@twinsun.com>
9011 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
9012 innocuous variant befor including <limits.h> or <assert.h>. This
9013 works around a bug reported by Albert Chin: HP-UX 11i
9014 (and earlier versions) have a <limits.h> that declares
9015 gettimeofday and many other functions.
9017 2002-12-03 Paul Eggert <eggert@twinsun.com>
9019 Version 2.57.
9021 * NEWS, configure.ac: Update version.
9023 * doc/fdl.texi: Upgrade to FDL version 1.2.
9025 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
9026 nontrivially in main's body, so that f's external declaration is
9027 not optimized away in AIX. This should fix the bug reported by
9028 Martin Frydl in
9029 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
9031 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
9032 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
9033 defined, to support freestanding compilers. This should fix the
9034 bug reported by Momchil Velkov in
9035 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
9037 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
9038 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
9039 obsolete AC_CHECK_TYPE. The missing empty arg was reported
9040 by Simon Josefsson in

9043 * Makefile.maint (www-gnu): New macro.
9044 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
9045 the location has moved.
9047 2002-12-02 Martin Frydl <martin@systinet.com>
9049 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
9050 \(.*\) match is too long and there is something more to be checked.
9051 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
9053 2002-11-15 Akim Demaille <akim@epita.fr>

9058 From Paul Eggert.
9059 * config/move-if-change: Indenting changes.
9060 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
9061 * configure.ac (AM_INIT_AUTOMAKE): here.
9062 Require 1.7.1.
9064 2002-11-14 Akim Demaille <akim@epita.fr>
9066 Version 2.55.
9068 * config/config.guess, config/config.sub, config/install-sh:
9069 Update from masters.
9071 2002-11-14 Akim Demaille <akim@epita.fr>
9073 * Makefile.maint: Sync with Bison, i.e.:
9074 (po-check): Scan .l and .y files instead of the
9075 .c and the .h files that they generate. This fixes the bug
9076 reported by Tim Van Holder in:
9077 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
9078 Look for N_ as well as for _. Try to avoid matching #define for
9079 N_ and _.
9080 From Paul Eggert.
9082 2002-11-14 Akim Demaille <akim@epita.fr>
9084 * doc/autoconf.texi (C Compiler): Compiling several files at once.
9085 From Paul Eggert and Albert Chin-A-Young.
9087 2002-11-14 Akim Demaille <akim@epita.fr>
9089 * doc/autoconf.texi (C Compiler): Solitary backslashes.
9090 From Paul Eggert and Albert Chin-A-Young.
9092 2002-11-14 Kevin Ryde <user42@zip.com.au>
9094 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
9095 than assigning in main, to avoid HP cc +O3 optimizing it away.
9097 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
9099 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
9100 option. Process --recheck after parsing all options. Pass -q
9101 option to configure on --recheck.
9102 (AC_OUTPUT): Pass -q from configure to config.status.
9103 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
9104 arguments to record.
9105 * doc/autoconf.texi (config.status Invocation): Document
9106 config.status -q option.
9108 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
9110 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
9111 Makefile.in if Makefile.am exists.
9112 (output): Strip `.am' from Makefiles. Don't
9113 output AC_CONFIG_FILES if no Makefiles were found.
9115 2002-11-07 Akim Demaille <akim@epita.fr>
9117 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
9118 (local_updates): New.
9119 * Makefile.maint: Update, from CVS Bison.
9120 (local_updates): New.
9122 2002-11-06 Akim Demaille <akim@epita.fr>
9124 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
9125 declaration in extern "C" too.
9126 Reported by Roberto Bagnara.
9128 2002-11-06 Akim Demaille <akim@epita.fr>
9130 * tests/torture.at (Configuring subdirectories): Don't use grep
9131 -w.
9132 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
9133 Reported by Ezra Peisach.
9135 2002-11-05 Akim Demaille <akim@epita.fr>
9137 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
9138 Remove.
9139 We _have_ to stop using the old compatibility scheme that tried to
9140 avoid useless backslashes because Libtool 1.4.3 contains a
9141 AC_DEFINE([error_t], [int],
9142 [Define to a type to use for \`error_t' if it is not
9143 otherwise available.])
9144 We _have_ to quote the single quote and backslashes with \. The
9145 old compatibility scheme saw that ` was backslashed, and therefore
9146 did not quote the single quote. Hence before this patch, Autoconf
9147 was not compatible with Libtool.
9149 2002-11-04 Paul Eggert <eggert@twinsun.com>
9151 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
9152 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
9153 LC_NAME, LC_PAPER, LC_TELEPHONE.
9154 * doc/autoconf.texi (Special Shell Variables): Mention those vars.
9156 2002-11-04 Akim Demaille <akim@epita.fr>
9158 Version 2.54c.
9160 * Makefile.maint (update, cvs-update, po-update, do-po-update):
9161 New.
9162 * config/texinfo.tex: Update.
9164 2002-11-03 Akim Demaille <akim@epita.fr>
9166 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
9167 from...
9168 (&autoreconf): here.
9169 ($help, $make, &parse_args, &autoreconf_current_directory):
9170 Support -m/--make.
9171 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9173 2002-10-31 Bruno Haible <bruno@clisp.org>

9245 * tests/torture.at (Deep Package): New test.

9479 2002-10-22 Akim Demaille <akim@epita.fr>
9481 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

9485 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
9486 strings.
9488 2002-10-22 Akim Demaille <akim@epita.fr>
9490 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

9537 longer required can still cause errors.
9538 Reported by Alexandre Duret-Lutz.
9540 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
9541 to frozen files in @ARGV, as @ARGV must remain being a list of

9543 (&files_to_options): New function.
9544 (&freeze): Use &error.
9545 (&up_to_date): If a file that was included according to the cache
9546 is no longer there, then the output is out dated.
9547 (&main): Don't even check whether a file is up to date is anyway
9548 --force is given.
9549 * tests/tools.at (autom4te cache): New.
9551 2002-10-16 Akim Demaille <akim@epita.fr>

9556 Factor some code.
9557 (&autoreconf): Report the directories we enter *and leave*, so
9558 that error messages can be easily located, and use GNU Make
9559 format, so that Emacs' compile mode understands us.
9560 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
9561 if some file was changed instead of `print'.
9562 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

9596 file name to enable parallel executions.
9597 From Sam Varshavchik.
9599 2002-10-08 Akim Demaille <akim@epita.fr>
9601 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
9602 aclocal invocation, as Gettext macros might not be visible to
9603 aclocal.
9604 Instead of blindly running autopoint, scan configure.ac (not the
9605 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
9606 Reported by Paul D. Smith.
9608 2002-10-08 Paul Eggert <eggert@twinsun.com>
9610 Work around problems found when POSIXLY_CORRECT=1 is set.
9611 None of this seems to have anything to do with POSIX, really,
9612 but it's how Perl getopt works.
9613 * bin/autom4te.in (parse_args): Configure GetOpt with
9614 "permute", too.
9615 * doc/autoconf.texi (Invoking autom4te):
9616 --warning -> --warnings.

9638 * tests/torture.at (Configuring subdirectories): Be robust to
9639 users who use config.site to require for a cache: in this case,
9640 the two last configure runs, using two different sets of
9641 arguments, trigger a legitimate error.
9643 2002-09-28 Akim Demaille <akim@epita.fr>
9645 * tests/m4sh.at (Functions Support, Functions and return Support):
9646 New.

9659 (tm_zone): Move their rules to...
9660 * lib/autoconf/types.m4: here, using AN_ macros.
9661 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
9662 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
9663 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
9664 * lib/autoconf/programs.m4: here.

9669 2002-09-28 Akim Demaille <akim@epita.fr>
9671 * lib/autoconf/autoscan.m4: New file.
9672 * lib/autoconf/autoconf.m4: Include it.
9673 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
9674 that were listed in the original autoscan.list.
9675 * lib/autoconf/headers.m4: Similarly with headers.
9676 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
9677 (.m4.m4f): Don't pass --prepend-include, since that's done by
9678 tests/autom4te itself.
9679 * lib/autoscan/Makefile.am: Include freeze.mk.
9680 (autoscan.list): New target --this file is no longer a source.
9681 (autoscan.pre): New file.
9683 2002-09-28 Akim Demaille <akim@epita.fr>
9685 * bin/autoscan.in (@kinds): Make them singular.
9686 Adjust all uses.
9687 (&init_tables): When --debug, report the list of rules to ease
9688 tracking changes in autoscan.list.
9689 * lib/autoscan/autoscan.list (function): Strip comments, sort.
9691 2002-09-28 Akim Demaille <akim@epita.fr>
9693 * lib/autoscan/functions, lib/autoscan/headers,
9694 * lib/autoscan/identifiers, lib/autoscan/makevars,
9695 * lib/autoscan/programs: Merge into...
9696 * lib/autoscan/autoscan.list: this.
9697 * bin/autoscan.in (&init_tables): Adjust.
9699 2002-09-28 Akim Demaille <akim@epita.fr>
9701 * lib/autoscan/functions, lib/autoscan/headers,
9702 * lib/autoscan/identifiers, lib/autoscan/makevars,
9703 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
9704 `functions' line is now prefixed with `function:'.
9705 * bin/autoscan.in (&init_tables): Adjust.
9707 2002-09-28 Akim Demaille <akim@epita.fr>
9709 From now on, autoscan files must always map a macro name to a
9710 word: there is no `default' macro for autoscan.
9712 * bin/autoscan.in (&init_tables): Reject entries with no macro at
9713 all.
9714 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
9715 explicit.
9717 2002-09-28 Akim Demaille <akim@epita.fr>
9719 * bin/autoscan.in (%c_keywords): Remove.
9720 (&used): Keep only track of the words we might be interested in.
9721 (&output_kind): It is no longer needed to look for non active
9722 checks.
9724 2002-09-27 Akim Demaille <akim@epita.fr>
9726 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
9727 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
9728 * lib/autoscan/functions: Adjust.
9729 * doc/autoconf.texi (Particular Functions): Adjust.
9731 2002-09-27 Akim Demaille <akim@epita.fr>
9733 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
9734 from /tmp.
9735 Thanks to Bill Moseley and Paul Eggert.
9736 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
9737 the tmpdir must be created.
9738 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
9739 dir be in the build tree, instead of $TMPDIR.
9741 2002-09-27 Akim Demaille <akim@epita.fr>
9743 * bin/autoscan.in: Improve the comments.
9744 (&parse_args): Drop obsolete undocumented options.
9745 (&output_kind): Output warnings.
9746 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

9752 Reported by Ralf Corsepius.
9753 * doc/autoconf.texi (autoreconf Invocation): Likewise.
9755 2002-09-26 Akim Demaille <akim@epita.fr>
9757 Single suffix rules and seperated dependencies are not portable.
9759 * doc/autoconf.texi (Installation Directory Variables): Update.
9760 (Limitations of Make): Some about `Single Suffix Rules and
9761 Separated Dependencies'.
9762 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9763 (ifnames, autoscan, autom4te): Un-factor into several rules.
9765 2002-09-25 Paul Eggert <eggert@twinsun.com>
9767 * BUGS (Interoperability bugs): New section. Mention libtool
9768 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
9770 2002-09-24 Paul Eggert <eggert@twinsun.com>
9772 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
9773 make handles suffix-rules differently from GNU make.
9775 * bin/Makefile.am (SUFFIXES, .in): Remove.
9776 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
9777 Move the body of the old .in rule here.
9779 2002-09-16 Akim Demaille <akim@epita.fr>
9781 i960 compilers create `b.out' files by default.
9782 Reported by Ralf Corsepius.
9784 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
9785 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
9787 2002-09-13 Paul Eggert <eggert@twinsun.com>
9789 * doc/autoconf.texi (Particular Headers): Remove obsolete
9790 reference to `struct timezone' in the description of
9791 AC_HEADER_TIME.
9793 2002-09-13 Akim Demaille <akim@epita.fr>
9795 Version 2.54.
9797 * config/config.sub, config/config.guess: Update.
9798 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
9799 * Makefile.am: Adjust.
9801 2002-09-13 Akim Demaille <akim@epita.fr>
9803 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
9804 reading config.log when the compiler is rejected.
9805 Suggested by Guido Draheim.
9807 2002-09-13 Akim Demaille <akim@epita.fr>
9809 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
9810 (chdir_init) might hang when stat'ing mounted directories.
9811 Reported by Vance Shipley.
9813 2002-09-12 Akim Demaille <akim@epita.fr>
9815 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
9816 the lists.
9818 2002-09-12 Akim Demaille <akim@epita.fr>
9820 * doc/autoconf.texi (Defining Symbols): Present two different
9821 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
9822 difference between 1 argument calls, and 2-3 argument calls.
9824 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
9826 * doc/autoconf.texi: Review grammar and punctuation.
9828 2002-09-11 Paul Eggert <eggert@twinsun.com>
9830 * doc/autoconf.texi: Fix minor formatting, spelling, and
9831 grammatical typos.
9832 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
9833 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
9834 is obsolescent.
9836 2002-09-11 Akim Demaille <akim@epita.fr>
9838 * doc/autoconf.texi (Questions): Rename as...
9839 (FAQ): this.
9840 (Defining Directories): New.
9842 2002-09-09 Akim Demaille <akim@epita.fr>
9844 * doc/autoconf.texi (Making testsuite Scripts): Update.
9845 Suggested by Nishio Futoshi.
9847 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
9849 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
9850 plain `@' is wanted.
9852 2002-09-09 Akim Demaille <akim@epita.fr>
9854 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
9855 `duplicates', since the algorithm was too naive and could keep
9856 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
9857 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
9858 Reported by Ralf Corsepius.
9859 * tests/torture.at (Configuring subdirectories): Exercise these
9860 cases.
9862 2002-09-09 Akim Demaille <akim@epita.fr>
9864 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
9865 looking for a replacement file.
9866 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
9867 directory is relative.
9868 * doc/autoconf.texi (Generic Functions): Clarify the replacement
9869 directory definition.
9870 Reported by Andreas Schwab and Jim Meyering.
9872 2002-09-06 Akim Demaille <akim@epita.fr>
9874 * doc/autoconf.texi (Setting Output Variables): Clarify what
9875 precious variables are.
9876 Suggested by Pontus Skoeld.
9878 2002-09-05 Akim Demaille <akim@epita.fr>
9880 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9881 (ifnames, autoscan, autom4te): Since we don't only depend on
9882 configure.ac variables (such as VERSION etc.), but also on prefix
9883 and so forth, depend on Makefile, not configure.ac.
9884 Reported by Alexandre Duret-Lutz.
9885 * doc/autoconf.texi (Installation Directory Variables): Adjust.
9887 2002-09-05 Kevin Ryde <user42@zip.com.au>
9889 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
9890 doesn't seem to be confined to ia64, just say "some versions".
9892 2002-09-04 Akim Demaille <akim@epita.fr>
9894 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
9895 Automake 1.6c.
9896 * Makefile.am (maintainer-clean-local): Remove.
9897 (MAINTAINERCLEANFILES): Remove COPYING.
9899 2002-09-03 Paul Eggert <eggert@twinsun.com>
9901 * doc/autoconf.texi (Configuration Commands): Remove obsolete
9902 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
9903 Brinkmann.
9905 2002-09-03 Akim Demaille <akim@epita.fr>
9907 * configure.ac: Bump to 2.53d.
9908 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
9909 as of today, on Automake's team suggestion.
9911 2002-09-03 Akim Demaille <akim@epita.fr>
9913 Version 2.53c.
9915 2002-09-02 Akim Demaille <akim@epita.fr>
9917 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
9918 SITE_MACRO_DIR.
9919 * configure.ac: Disable SITE_MACRO_DIR.
9921 2002-09-02 Jim Meyering <meyering@lucent.com>
9923 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
9924 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
9925 Also, tweak grammar: s/make sure to/be sure to/.
9927 2002-09-02 Paul Eggert <eggert@twinsun.com>
9929 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
9930 directory names are generally preferable to physical names.
9932 2002-09-02 Akim Demaille <akim@epita.fr>
9934 * lib/Autom4te/General.pm (&update_file): s/die/error/.
9935 Reported by Raja R. Harinath.
9936 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
9937 * bin/autoupdate.in: Use error instead of die.
9939 2002-09-01 Paul Eggert <eggert@twinsun.com>
9941 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
9942 ordinary shell concatenation rather than echo+tr+sed command that
9943 runs afoul of a long-line-related sed bug in Solaris 8.
9945 * bin/autoheader.in (parse_args): --warning -> --warnings.
9947 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
9948 stdout, as traditional "ls" does.
9949 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
9950 _AC_COMPILER_EXEEXT_O): Likewise.
9951 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
9953 * bin/autoconf.as: Add --prepend-include option. This patch was
9954 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
9955 but bin/autoconf.in is generated automatically from bin/autoconf.as.
9957 * bin/autoconf.in, configure: Regenerate.
9959 * doc/autoconf.texi (Special Shell Variables): Mention
9960 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
9962 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
9963 MAILPATH and set PS1, PS2, PS4 to default values, to work
9964 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
9965 For LC_ALL etc, first try to set to "C" as POSIX requires and as
9966 the Autoconf documentation specifies; fall back to "unset" only if
9967 this fails. Use a shell for-loop for this rather than an m4 loop,
9968 to shorten the output script.
9970 2002-08-30 Paul Eggert <eggert@twinsun.com>
9972 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
9973 1003.1-2001's requirements for CDPATH. Give a simpler workaround
9974 for the CDPATH problem. Document PWD.
9975 (Limitations of Builtins): Document the problem that "cd $foo" and
9976 "ls $foo" may refer to different directories in shells conforming
9977 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
9978 example, since the old example is now out of date.
9980 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
9981 FOO" and "ls FOO" talk about different directories; this catches
9982 problems when POSIX 1003.1-2001 "cd" fails due to symlink
9983 spaghetti.
9985 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
9986 of rolling our own unset.
9987 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
9988 in practice we needn't worry about CDPATH if unset doesn't work.
9990 * Makefile.in, aclocal.m4, bin/Makefile.in,
9991 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
9992 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
9993 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
9994 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
9995 tests/Makefile.in: Regenerate with Automake 1.6.3.
9997 * config/config.guess, config/config.sub, config/mkinstalldirs:
9998 Update.
10000 * configure: Regenerate with self.
10002 2002-08-30 Kevin Ryde <user42@zip.com.au>
10004 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
10005 default output.
10007 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
10009 * bin/autom4te.in (Request::load): Correctly test for "do" read
10010 failure.
10012 2002-08-29 Akim Demaille <akim@epita.fr>
10014 * lib/Autom4te/General.pm (&xqx): New.
10015 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
10016 hand, which is not portable.
10017 (&error): New.
10018 * bin/autom4te.in: Use them.
10019 Use &error instead of die.
10020 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
10021 Adjust.
10023 2002-08-17 Paul Eggert <eggert@twinsun.com>
10025 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
10026 default list of compilers to try, since it was long ago superseded
10027 by the ksh fc builtin. Suggested by Steven G. Johnson.
10029 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
10031 * doc/autoconf.texi (Invoking autom4te): End the option table,
10032 fixing a bug introduced by the previous patch.
10033 (Limitations of Make): Add a 'target lookup' subentry in the
10034 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
10036 2002-07-29 Mark D. Roth <roth@feep.net>
10038 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
10039 options and use $AUTOM4TE_PATH.
10040 * doc/autoconf.texi: Remove documentation of autom4te
10041 --include-envvar and --site-macro-subdir options and document
10042 use of $AUTOM4TE_PATH.
10043 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
10044 arguments from each language section.
10046 2002-07-29 Paul Eggert <eggert@twinsun.com>
10048 * doc/install.texi: Include copyright symbol in copyright notice.
10050 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
10051 Replace with:
10052 (AM_MAKEINFOFLAGS): New macro.
10053 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
10054 * Makefile.am (INSTALL): Use the new macros.
10055 Use -o rather than --output, since "missing" does not grok --output.
10057 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
10059 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
10060 comments do not always work. Never trust the exit status of
10061 `make -k'.
10063 2002-07-24 Kevin Ryde <user42@zip.com.au>
10065 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
10066 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
10068 2002-07-23 Paul Eggert <eggert@twinsun.com>
10070 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
10071 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
10072 apparently treats PATH="nonexistent" as if it contained ".".
10073 Bug reported by Stefan `Sec' Zehl.
10075 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10077 * doc/autoconf.texi (Limitations of Make): Mention the special
10078 handling of the obj/ directory by BSD make.
10080 2002-07-20 Kevin Ryde <user42@zip.com.au>
10082 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
10083 backslashes.
10085 2002-07-19 Akim Demaille <akim@epita.fr>
10087 * doc/autoconf.texi (Function Portability): `exit'.
10088 (Programming in M4sh): Ethymology of M4sh.
10090 2002-07-19 Akim Demaille <akim@epita.fr>
10092 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
10094 2002-07-18 Akim Demaille <akim@epita.fr>
10096 Version 2.53b.
10098 2002-07-18 Akim Demaille <akim@epita.fr>
10100 * config/config.guess, config/config.sub: Update.
10102 2002-07-18 Akim Demaille <akim@epita.fr>
10104 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
10105 Automake's parts.
10107 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
10108 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
10109 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
10111 2002-07-18 Akim Demaille <akim@epita.fr>,
10112 Alexandre Duret-Lutz <duret_g@epita.fr>
10114 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
10115 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
10117 2002-07-17 Russ Allbery <rra@stanford.edu>
10119 * doc/autoconf.texi (Initializing configure): Clarify the
10120 description of the tarname default.
10122 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
10124 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
10125 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
10126 latter was not run.
10128 2002-07-17 Akim Demaille <akim@epita.fr>
10130 * lib/Autom4te/General.pm (find_file): Browse the directories in
10131 the order they are given.
10133 2002-07-17 Akim Demaille <akim@epita.fr>
10135 * tests/wrapsh.as, tests/wrappl.as: Merge into...
10136 * tests/wrapper.as: this.
10137 * tests/Makefile.am, configure.ac: Adjust.
10139 2002-07-17 Mark D. Roth <roth@feep.net>
10141 * configure.ac: Add --enable-site-macro-dir option.
10142 * bin/Makefile.am: Expand @SITE_MACRO_DIR@.
10143 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
10144 --site-macro-subdir options.
10145 * bin/autoconf.in: Add --prepend-include option.
10146 * bin/autoheader.in: Add --prepend-include option.
10147 * bin/autoreconf.in: Add --prepend-include option.
10148 * bin/autoscan.in: Add --prepend-include option.
10149 * bin/autoupdate.in: Add --prepend-include option.
10150 * doc/autoconf.texi: Document use of $AC_MACRO_PATH and site
10151 macro directory, remove note that include path directories are
10152 used in reverse order, and document --prepend-include option.

10234 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>

10238 was installed.

10266 * bin/autom4te.in (warn_forbidden): When rejecting a token,
10267 suggest m4_pattern_allow.
10268 Suggested by Adam J. Richter.
10270 2002-06-07 Akim Demaille <akim@epita.fr>
10272 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
10273 ac_config_libobj_dir.
10274 (AC_CONFIG_LIBOBJ_DIR): New.
10275 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

10333 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
10334 from the default list of compilers to try. Suggested by
10335 Kate Hedstrom.
10336 * NEWS: Document the above.
10337 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
10339 2002-05-17 Paul Eggert <eggert@twinsun.com>
10341 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
10342 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
10343 This improves on an earlier suggestion by H. Peter Anvin.
10345 2002-05-16 Paul Eggert <eggert@twinsun.com>
10347 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
10348 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
10349 Both macros now accept an optional source-dir arg.
10350 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
10352 * NEWS: Document this.
10353 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
10355 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
10356 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
10357 not for GNU extensions; this undoes part of the 2000-11-03 change,
10358 reverting to 2.13-compatible behavior.
10359 Add new optional argument DIR.
10360 (AC_FUNC_FNMATCH_GNU): New macro.
10362 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
10364 2002-05-08 Paul Eggert <eggert@twinsun.com>
10366 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
10367 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
10368 and it causes a 'test' syntax error if it fails.
10369 Bug reported by Stephen Gildea.
10371 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
10372 If prototypes are supported, use them to check this at compile-time,
10373 instead of trying to check it at run-time. If we must do a run-time
10374 check, assume that setvbuf is standard when cross-compiling, as
10375 nonstandard setvbuf occurs only on ancient and unlikely hosts.
10376 Bug reported by Paul D. Smith.
10378 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
10379 argument specifying location of getloadavg.c. This removes a
10380 FIXME. This idea was taken from Jim Meyering's implementation in
10381 textutils.
10382 * doc/autoconf.texi (Particular Functions): Document this.
10383 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
10384 that's what the code does; this fixes a bug reported by
10385 Paul D. Smith.
10387 2002-05-03 Akim Demaille <akim@epita.fr>
10389 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
10390 autopoint instead of gettextize.
10391 ($uses_alocal): Rename as...
10392 ($uses_aclocal): this.
10393 * doc/autoconf.texi (autoreconf Invocation): Adjust.
10394 Suggested by Bruno Haible.
10396 2002-05-03 Akim Demaille <akim@epita.fr>
10398 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
10400 2002-04-29 Paul Eggert <eggert@twinsun.com>
10402 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
10403 files to be 1 second older; just set them to be the same time.
10404 Also, sleep 1 second after the first aclocal, to work around
10405 problems with sub-second time stamps on the input files.
10407 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
10409 * doc/autoconf.texi: Mention "set -e -x" lossage
10410 under node "Limitations of Builtins".
10412 2002-04-29 Akim Demaille <akim@epita.fr>
10414 * doc/install.texi: Better wording for setting variables when
10415 running configure.
10416 From Christian Cornelssen.
10418 2002-04-29 Akim Demaille <akim@epita.fr>
10420 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
10421 of lack of $LINENO support, then the test will compare the $LINENO
10422 in testsuite vs. the lineno in the test file. This is wrong, of
10423 course.
10424 Be sure to protect it.
10425 Reported by Patrick Welche.
10427 2002-04-25 Akim Demaille <akim@epita.fr>
10429 * doc/autoconf.texi (Obsolete Macros): Typo.
10430 Reported by Vladimir Volovich.
10432 2002-04-25 Akim Demaille <akim@epita.fr>
10434 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
10435 than some of the input files, hence, on the second run of aclocal,
10436 if some of its input are younger, make them older.
10437 Suggested by Paul Eggert.
10439 2002-04-25 Akim Demaille <akim@epita.fr>
10441 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
10442 Thanks to Paul Eggert.
10444 2002-04-25 Akim Demaille <akim@epita.fr>
10446 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
10447 and ac_subst_vars be sh variables containing the list of
10448 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
10449 DEFAULT diversion.
10450 (_AC_INIT_PREPARE): Use them to log them.
10451 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
10452 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
10453 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
10454 _AC_SUBST_FILES and _AC_SUBST_VARS.
10455 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
10457 2002-04-24 Akim Demaille <akim@epita.fr>
10459 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
10460 autoheader, so that automake does not complain about a missing
10461 config.h.in that was to be created.
10463 2002-04-23 Akim Demaille <akim@epita.fr>
10465 * bin/autoheader.in (parse_args): --warning takes an argument.
10466 Fixes PR/220.
10468 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
10470 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

10517 * doc/autoconf.texi: Follow the outline suggested in the GNU
10518 Sample Texts sections of the Texinfo 4.2 manual. Most
10519 importantly, this makes sure that the copyright notices appear in
10520 all output formats. You probably need Texinfo 4.2 to generate
10521 the manual now.

10572 Adjust Autoconf and Autotest.

10576 * lib/autotest/general.m4 (AT_INIT): Likewise.
10577 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

10619 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
10620 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
10621 Use dnl, not the KILL diversion.
10622 Extracted from...
10623 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
10624 (AC_CONFIG_LINKS): here.
10625 Adjust.
10626 Don't use the KILL diversion, as it kills spurious output, which
10627 results in failures being hidden.
10628 Use m4_defn where appropriate.
10629 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
10630 after the second argument.
10631 Use m4_defn.
10632 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
10633 syntax, as it is provided by M4sugar.
10634 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
10636 2002-04-03 Andreas Schwab <schwab@suse.de>
10638 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
10639 expanded if $# <= 2.
10641 * bin/autoreconf.in (autoreconf): Run automake after rerunning
10642 aclocal.
10644 2002-04-03 Akim Demaille <akim@epita.fr>
10646 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
10647 (_AC_COMPILER_EXEEXT_REJECT): New.
10648 Also recognize *.bb and *.bbg as compilation byproducts.
10649 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
10650 (_AC_COMPILER_OBJEXT): Use them.
10651 Fixes Debian #138666.
10653 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
10655 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
10657 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
10658 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
10659 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
10660 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
10661 (AC_C_CONST): Same.
10662 (AC_C_INLINE): Same.
10663 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
10664 * doc/autoconf.texi, NEWS: Document.
10665 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
10666 AC_C_CROSS.
10668 2002-04-02 Akim Demaille <akim@epita.fr>
10670 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
10671 _AS_MKDIR_P_PREPARE.
10673 2002-03-28 Kevin Ryde <user42@zip.com.au>
10675 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
10676 to avoid versions of HP C which don't allow that.
10678 2002-03-27 Paul Eggert <eggert@twinsun.com>
10680 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
10681 (AS_SHELL_SANITIZE): Invoke it.
10682 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
10684 2002-03-26 Akim Demaille <akim@epita.fr>
10686 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
10688 2002-03-26 Akim Demaille <akim@epita.fr>
10690 * doc/autoconf.texi (Introduction): The GNATS base moved.
10692 2002-03-25 Paul Eggert <eggert@twinsun.com>
10694 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
10695 as POSIX requires, as it doesn't work with Zsh.
10696 * doc/autoconf.texi (Assignments): Document the problem.
10698 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
10700 * doc/autoconf.texi (Limitations of Make): Mention more issue
10701 about VPATH, overriding of macros in sub-makes, and handling of
10702 SHELL.
10704 2002-03-21 Paul Eggert <eggert@twinsun.com>
10706 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
10707 problem with here-document buffer boundaries.
10709 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
10710 when reinvoking the shell, to work around problems with installers
10711 who put strange things like "cd" commands in their environments.
10713 2002-03-19 Akim Demaille <akim@epita.fr>
10715 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
10716 From Aaron Ucko.
10718 2002-03-19 Akim Demaille <akim@epita.fr>
10720 * bin/autoscan.in (scan_file): Specify the location in `&used'
10721 invocations.
10722 From Nicolas Joly.
10724 2002-03-19 Akim Demaille <akim@epita.fr>
10726 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
10727 From Nishio Futoshi.
10729 2002-03-19 Akim Demaille <akim@epita.fr>
10731 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
10733 2002-03-18 Paul Eggert <eggert@twinsun.com>
10735 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
10736 (Limitations of Usual Tools): Add mkdir section.
10738 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
10739 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
10740 back on AS_DIRNAME to compute prefixes otherwise; this is
10741 roughly what mkinstalldirs does. That way, we need not have
10742 our own filename disassembler. The old disassembler did not
10743 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
10745 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
10746 Create at_test_all by a series of assignments,
10747 not by a single assignment of a long string. The latter causes ksh
10748 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
10749 presumably because of a buffer overrun.
10751 2002-03-14 Paul Eggert <eggert@twinsun.com>
10753 * lib/autotest/general.m4 (at_times_skip):
10754 Renamed from at_times. Now a boolean.
10755 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
10756 says 'times: not found'.
10758 2002-03-14 Akim Demaille <akim@epita.fr>
10760 * bin/autoreconf.in (&study_gettextize): New.
10761 (&autoreconf): Handle newest gettextize.
10762 Rerun aclocal if needed.
10763 Suggested by Andreas Schwab.
10765 2002-03-13 Akim Demaille <akim@epita.fr>
10767 * doc/autoconf.texi (Special Shell Variables): More about IFS.
10769 2002-03-13 Akim Demaille <akim@epita.fr>
10771 * doc/autoconf.texi (Header Portability): New.
10772 Add information about stdint.h and inttypes.h from Paul Eggert.
10774 2002-03-13 Akim Demaille <akim@epita.fr>
10776 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
10777 -p'.
10778 From Bob Proulx.
10780 2002-03-12 Akim Demaille <akim@epita.fr>
10782 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
10783 m4_require.
10785 2002-03-11 Andreas Schwab <schwab@suse.de>
10787 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
10788 does not do it if --with-lispdir is given.
10790 2002-03-08 Akim Demaille <akim@epita.fr>
10792 Version 2.53.
10794 2002-03-08 Akim Demaille <akim@epita.fr>
10796 * doc/autoconf.texi (Subdirectories): Clarify that the
10797 subdirectory should exist.
10799 2002-03-08 Akim Demaille <akim@epita.fr>
10801 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
10803 2002-03-08 Akim Demaille <akim@epita.fr>
10805 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
10806 aliases the actual variables, and modifications of the former
10807 affect the latter.
10809 2002-03-08 Akim Demaille <akim@epita.fr>
10811 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
10812 because of C-c: have m4 output in tmp files, then mv them.
10814 2002-03-08 Akim Demaille <akim@epita.fr>
10816 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
10817 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
10818 * bin/ifnames.in: Copyright update.
10820 2002-03-08 Akim Demaille <akim@epita.fr>
10822 * doc/autoconf.texi (Invoking autom4te): New.
10824 2002-03-05 Akim Demaille <akim@epita.fr>
10826 * doc/autoconf.texi (Specifying Names): Clarification suggested by
10827 Kevin Ryde.
10829 2002-03-05 Akim Demaille <akim@epita.fr>
10831 Version 2.52i.
10833 2002-03-04 Akim Demaille <akim@epita.fr>
10835 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
10836 * lib/autoconf/general.m4 (AC_INIT): More informative error
10837 message for LIBOBJ.
10839 2002-03-04 Akim Demaille <akim@epita.fr>
10841 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
10842 parallel builds.
10844 2002-03-04 Akim Demaille <akim@epita.fr>
10846 * doc/autoconf.texi (Transforming Names): Equality between target
10847 and host is irrelevant.
10848 (Specifying Names, Canonicalizing): Remove all references to the
10849 backward compatibility hooks. Rather, collect them all into...
10850 (Hosts and Cross-Compilation): this new section.
10851 * doc/install.texi (System Type): Ditto.
10852 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
10853 that `--host' implies cross-compilation.
10855 2002-03-04 Akim Demaille <akim@epita.fr>
10857 * doc/autoconf.texi (Evaluation Macros): New.
10858 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
10859 useless.
10860 (_m4_foreach): Define the variant with immediate evaluation so
10861 that it contains exactly the items, not an expression which
10862 evaluation is the current item.
10863 (m4_re_string, m4_re_word): Don't over quote them.
10865 2002-03-04 Akim Demaille <akim@epita.fr>
10867 Instead of having stacking `shift's evaluated at the end, let
10868 `foreach' loops immediately evaluate them.
10870 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
10871 $*. This is the n-th time I change my mind, but hopefully this is
10872 the last...
10873 (m4_lquote): New.
10874 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
10875 efficient.
10876 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
10877 it was only a hack for m4_text_wrap.
10878 (m4_car2): Remove, replaced by...
10879 (m4_cdr): New.
10880 (_m4_foreach): Adjust.
10881 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
10882 m4_bpatsubst for clarification.
10884 2002-03-04 Akim Demaille <akim@epita.fr>
10886 * doc/autoconf.texi (Changequote is Evil): New.
10888 2002-03-03 Kevin Ryde <user42@zip.com.au>
10890 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
10891 on old systems like SunOS.
10893 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
10895 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,

10899 of messages.
10901 2002-02-28 Akim Demaille <akim@epita.fr>
10903 * lib/autotest/general.m4 (AT_INIT): Suggest a title to the
10904 message to be sent.

10913 From Akinori Musha.
10915 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
10917 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
10918 translate \r\n to \n.
10920 2002-02-07 Akim Demaille <akim@epita.fr>
10922 Version 2.52h.
10924 2002-02-07 Akim Demaille <akim@epita.fr>
10926 Fix Autoconf PR/209.
10927 Also reported by Frank Denis.
10929 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
10931 2002-02-07 Akim Demaille <akim@epita.fr>
10933 Fix Autoconf PR/207:
10934 AC_PREFIX_PROGRAM fails with dashed program names
10936 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
10937 variable when looking for the prefix program.
10938 Now it also works for shell variables.
10940 2002-02-07 Akim Demaille <akim@epita.fr>
10942 * doc/autoconf.texi (Limitations of Builtins): More about
10943 case/esac.
10945 2002-02-06 Akim Demaille <akim@epita.fr>
10947 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
10948 case/esac, some shells don't support it.
10949 Reported by Zack Weinberg.
10950 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
10952 2002-02-06 Akim Demaille <akim@epita.fr>
10954 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
10955 sure not to introduce newlines in at_groups.
10956 * lib/autotest/Makefile.am (autotest.m4f): Typo.
10958 2002-02-06 Akim Demaille <akim@epita.fr>
10960 * tests/torture.at (Configuring subdirectories): Skip if aclocal
10961 is not available.
10963 2002-02-05 Paul Eggert <eggert@twinsun.com>
10965 * doc/autoconf.texi (Specific Compiler Characteristics):
10966 Describe HP-UX cc bug workaround more accurately.
10967 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
10968 not unsigned long.
10969 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
10970 cross-compilers, too. This undoes some of the most recent change
10971 to this file.
10973 2002-02-05 Akim Demaille <akim@epita.fr>
10975 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
10976 to make sure they are up to date when `check' is run.
10978 2002-02-05 Akim Demaille <akim@epita.fr>
10980 * doc/autoconf.texi (Making testsuite Scripts): Document
10981 package.m4.

10985 * lib/freeze.mk: New.
10987 2002-02-05 Akim Demaille <akim@epita.fr>
10989 Implement `autom4te --freeze'.
10991 * bin/autom4te.in (&freeze): New.
10992 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
10993 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
10995 2002-02-05 Akim Demaille <akim@epita.fr>
10997 * bin/autom4te.in (&parse_args): Implement `frozen files are
10998 optional are the sum of the previous files on the command line'.
10999 Also, pass `--reload-state=' on them, so...
11000 (handle_m4): don't.
11001 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
11002 (M4sh): Rely on M4sugar.
11003 (Autotest, M4sh, M4sugar): Use frozen files.
11005 2002-01-31 Akim Demaille <akim@epita.fr>
11007 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
11008 * doc/autoconf.texi (Initializing configure): Adjust.
11010 2002-01-30 Akim Demaille <akim@epita.fr>
11012 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
11013 alphanumeric to `-' instead of `_'.
11015 2002-01-30 Akim Demaille <akim@epita.fr>
11017 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
11018 for plain code, the other for cross-compilation code. The latter
11019 is now run with GCC only.
11020 * doc/autoconf.texi (Compilers and Preprocessors): New.
11022 2002-01-30 Akim Demaille <akim@epita.fr>
11024 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
11025 values.
11026 * doc/autoconf.texi (Initializing configure): Explain how to
11027 change AC_INIT default values.
11029 2002-01-29 Akim Demaille <akim@epita.fr>
11031 * tests/torture.at (Configuring subdirectories): Use configure.in,
11032 so that aclocal 1.4 works.
11033 Reported by Alexandre Duret-Lutz and Larry Schmitt.
11035 2002-01-28 Akim Demaille <akim@epita.fr>
11037 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
11038 needs an argument.
11040 2002-01-28 Akim Demaille <akim@epita.fr>
11042 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
11043 AUTOTEST_PATH *after* it was set.
11044 Don't put `.' in the PATH: the user should be precise and `./' if
11045 needed. In addition, given that the test suite does some `cd', if
11046 `.' is in the path, the `tested programs' sections will report
11047 programs found in the test suite's directory, while during the
11048 tests (performed in their own directory), these programs are no
11049 longer visible. In other words, the results is confusing and
11050 useless.
11051 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
11053 2002-01-24 Akim Demaille <akim@epita.fr>

11062 2002-01-24 Akim Demaille <akim@epita.fr>
11064 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
11065 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
11066 Bourne. Use /bin/sh.
11067 From Andreas Buening.
11069 2002-01-24 Akim Demaille <akim@epita.fr>
11071 * config/config.guess, config/config.sub, config/texinfo.tex:

11079 * config/missing.m4, config/sanity.m4, config/select.m4,
11080 * config/strip.m4: Remove, to ease sync'ing with any version of
11081 Automake.
11083 2002-01-24 Akim Demaille <akim@epita.fr>
11085 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
11086 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
11087 Reported by Geir Ove Myhr.
11089 2002-01-21 Akim Demaille <akim@epita.fr>
11091 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
11093 2002-01-21 Akim Demaille <akim@epita.fr>
11095 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
11096 message on invalid options.
11097 * bin/autom4te.in (parse_args): Don't use
11098 Autoconf::General::getopt with non valid options.
11100 2002-01-17 Jim Meyering <meyering@lucent.com>
11102 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
11103 $ac_cv_exeext so we don't use an old, invalid, cached value.
11105 2002-01-11 Akim Demaille <akim@epita.fr>
11107 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
11108 Meyering.

11114 2002-01-06 Akim Demaille <akim@epita.fr>
11116 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
11117 package.m4, since is really depends upon configure.ac, not
11118 configure.
11119 * doc/autoconf.texi (testsuite Scripts): Adjust.
11120 * tests/Makefile.am (package.m4): New.
11121 EXTRA_DIST it since its a source.
11123 2002-01-06 Akim Demaille <akim@epita.fr>
11125 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
11126 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
11127 and PACKAGE_BUGREPORT from here...
11128 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
11129 arguments.
11130 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
11131 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
11132 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
11133 * tests/tools.at (autoheader): Adjust.
11134 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.

11142 * doc/autoconf.texi (Output): Improved wording regarding use of
11143 AC_OUTPUT.
11144 From Olly Betts.
11146 2001-12-18 Kevin Ryde <user42@zip.com.au>
11148 * doc/autoconf.texi (Function Portability): Add notes on sscanf
11149 sometimes needing writable input.
11151 2001-12-17 Jim Meyering <meyering@lucent.com>
11153 * doc/autoconf.texi (New Macros): Tweak wording.
11155 2001-12-14 Akim Demaille <akim@epita.fr>
11157 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
11158 trailing files, don't apply `-rf' to files which might not be
11159 created by configure (core, core.*, and *.core), but just `rm -f'.
11160 Suggested by Jonathan Kamens.
11162 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
11164 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
11166 2001-12-14 Akim Demaille <akim@epita.fr>
11168 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
11170 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
11172 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
11173 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
11174 abs_srcdir, top_srcpath to abs_top_srcdir.
11175 (_AC_OUTPUT_FILES): Adjust.
11176 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
11177 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
11178 * tests/wrappl.in, tests/wrapsh.in: Adjust.
11180 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
11182 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
11183 C/Fortran linking on HP/UX, by extracting the Fortran library
11184 search path from the LPATH line in the $F77 -v output.
11186 2001-12-12 Kevin Ryde <user42@zip.com.au>
11188 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
11189 forbidden file descriptors table.
11191 2001-11-26 Akim Demaille <akim@epita.fr>
11193 * bin/autoscan.in (%c_keywords): Build it at top level.
11194 Map to 1 in order to simplify its uses.
11196 2001-11-26 Akim Demaille <akim@epita.fr>
11198 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
11199 Remove $filepath, useless.
11200 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
11201 variables, they are really part of the tokens.
11202 Split the input line on spaces and then look for tokens.
11203 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
11204 because of `lex$U.$(OBJEXT)'.
11205 (&scan_files): Use "@list" instead of join.
11206 * doc/Makefile.am (CLEANFILES): Add *.fns.
11208 2001-11-26 Akim Demaille <akim@epita.fr>
11210 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
11211 Remove, replaced by...
11212 * tests/wrappl.in: Be common for all the Perl executables.
11213 In particular autoscan and autoheader want -I.
11214 * configure.ac: Adjust.
11215 * lib/autoscan/headers: errno.h is portable.
11217 2001-11-26 Akim Demaille <akim@epita.fr>
11219 * bin/autoscan.in (used): New.
11220 Use it.
11222 2001-11-26 Akim Demaille <akim@epita.fr>
11224 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
11225 directives.
11226 (&scan_sh_file): Remove a duplicate pattern.
11227 (&check_configure_ac): Use long options.
11228 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
11230 2001-11-26 Akim Demaille <akim@epita.fr>
11232 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
11233 Before, having a line containing the opening of a multi line
11234 comment made the whole line be ignored.
11236 2001-11-26 Akim Demaille <akim@epita.fr>
11238 * doc/autoconf.texi (Using an Autotest Test Suite): New.
11239 (testsuite Scripts): Be one of its subsection.
11240 (Autotest Logs): New.
11242 2001-11-26 Akim Demaille <akim@epita.fr>
11244 Test groups are now run two directories deeper.
11246 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
11247 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
11248 at_top_builddir.
11249 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
11250 top_srcdir, builddir and top_builddir.
11251 Use `at_*dir' relatively to the directory containing the
11252 suite, use `*dir' when relatively to the current group dir.
11254 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
11256 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
11257 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
11258 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
11259 spelling errors.
11261 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
11263 * doc/autoconf.texi (Using System Type): Add an example of `case
11264 $host' usage so people quit using `case $target' everywhere.
11266 2001-11-22 Akim Demaille <akim@epita.fr>
11268 * doc/autoconf.texi (Installation Directory Variables): Englishoes
11269 spotted by Jim Meyering.
11271 2001-11-16 Paul Eggert <eggert@twinsun.com>
11273 This patch implements a `long double' suggestion by Oliver Kiddle.
11275 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
11276 static, to catch errors if the value isn't known at compile-time
11277 and the compiler supports dynamic arrays. Change its name from
11278 `_array_' to `test_array' to avoid potential name clashes.
11279 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
11280 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
11281 better than double. Catch a bug in GCC 2.95.2 x86.
11282 * doc/autoconf.texi (C Compiler): Document the above.
11283 * NEWS: Likewise.
11285 2001-11-13 Akim Demaille <akim@epita.fr>
11287 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
11288 hand.
11289 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
11291 2001-11-13 Akim Demaille <akim@epita.fr>
11293 * lib/autotest/general.m4 (AT_INIT): After having run the test
11294 group, go back to the initial directory, not to at_suite_dir.
11296 2001-11-13 Akim Demaille <akim@epita.fr>
11298 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
11299 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
11300 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
11301 option.
11302 (AT_CHECK_CONFIGURE): Use absolute paths.
11303 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
11304 The problem is still the old one: there is no means in M4 (that I
11305 know about) to create a defining macro, because there is no means
11306 to create `$1' etc., therefore, the defining macro ``swallows''
11307 all the arguments meant to the defined macro.
11309 2001-11-13 Akim Demaille <akim@epita.fr>
11311 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
11312 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
11313 configure.ac.
11314 * tests/aclocal.m4: Remove, as it is no longer used.
11316 2001-11-13 Akim Demaille <akim@epita.fr>
11318 * lib/autotest/general.m4: Change `tests?' into `groups?' in
11319 variable names when referring to a single test group, or to
11320 `suite' when referring to the whole test suite.
11321 `at_last_test' is removed: m4 compute at_format itself.
11322 (at_stdout, at_stder1, at_stderr): New variables.
11323 (AT_CHECK): Use them.
11325 2001-11-13 Akim Demaille <akim@epita.fr>
11327 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
11328 in PATH.
11329 Create `testsuite.dir/003/run' instead of `testsuite.003'.
11330 Do it as soon as a test fails, don't wait till the end of the test
11331 suite.
11332 Don't remove $as_me.[0-9]*, since these files no longer exist.
11334 2001-11-13 Akim Demaille <akim@epita.fr>
11336 * tests/tools.at: Use absolute paths, since we are no longer run
11337 in place.
11339 2001-11-13 Akim Demaille <akim@epita.fr>
11341 Now that tests are running in their own private dir, there is no
11342 need to list the files to remove at the end of tests groups.
11344 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
11345 (AT_data_files, at_data_files): Remove.
11346 (AT_CLEANUP, AT_DATA): Simplify.
11347 (AT_INIT): Adjust.
11348 Remove the group dir if !debug && !failed.
11349 * tests/atspecific.m4: Adjust.
11351 2001-11-13 Akim Demaille <akim@epita.fr>
11353 Start a new layout for Autotest: `testsuite' creates
11354 `testsuite.dir' in which the at-check-line etc. files are to be
11355 found, and `testsuite.dir/003' where the test group 3 is run.
11357 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
11358 at_check_line_file, at_format, at_test_normalized, at_group_dir
11359 are new variables.
11360 Create the directories.
11361 Use absolute paths for at- files.
11362 (AT_CHECK): Adjust.
11364 2001-11-11 Michael Matz <matz@kde.org>
11366 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
11367 (m4_car2): New.
11368 (m4_car): Properly quote arguments.
11370 2001-11-13 Akim Demaille <akim@epita.fr>
11372 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
11373 with stricter rules on LIBOBJS.
11375 2001-11-12 Paul Eggert <eggert@twinsun.com>
11377 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
11378 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
11379 __PROTOTYPES too.
11381 2001-11-12 Akim Demaille <akim@epita.fr>
11383 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
11385 2001-11-12 Akim Demaille <akim@epita.fr>
11387 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
11388 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
11389 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11390 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
11391 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
11392 specify to what the macro should be defined (typically to 1).
11394 2001-11-12 Akim Demaille <akim@epita.fr>
11396 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
11397 From Jim Meyering.
11399 2001-11-12 Akim Demaille <akim@epita.fr>
11401 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11402 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
11403 definition used by Automake where LEX is +/- "${missing} lex" and
11404 `missing' itself contains variables.
11406 2001-11-12 Akim Demaille <akim@epita.fr>
11408 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
11409 Now that M4sh pushes BODY, the comments were output at the end of
11410 the test suites.
11412 2001-11-08 Akim Demaille <akim@epita.fr>
11414 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
11415 that we can trace macros from aclocal.m4.
11416 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
11417 obsoleted, and redirect to the former anyway.
11418 Reported by Ralf Corsepius.
11420 2001-11-08 Akim Demaille <akim@epita.fr>
11422 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
11423 processed only if present.
11424 * tests/torture.at (Configuring subdirectories): Use autoreconf
11425 instead of successive calls to autoconf.
11426 Add a nonexistent subdirectory to exercise the patch above.
11427 Reported by Ralf Corsepius.
11429 2001-11-08 Kevin Ryde <user42@zip.com.au>
11431 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
11432 doesn't accept .S files.
11434 2001-11-07 Akim Demaille <akim@epita.fr>
11436 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
11437 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
11438 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
11439 * bin/autom4te.in (warn_forbidden): New.
11440 (handle_output): Use it.
11441 Read m4_pattern_forbid with messages.
11443 2001-11-05 Akim Demaille <akim@epita.fr>
11445 * bin/autom4te.in (--normalize): Remove.
11446 * lib/autom4te.in: Adjust.
11448 2001-11-05 Akim Demaille <akim@epita.fr>
11450 * tests/Makefile.am (testsuite): Rename this target as...
11451 ($(TESTSUITE)): this.
11452 From Nicolas Joly.
11454 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
11456 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
11457 the --prefix option, also remove it's argument.
11459 2001-11-05 Akim Demaille <akim@epita.fr>
11461 * doc/autoconf.texi (testsuite Invocation): Update.
11462 (Writing testsuite.at): Update.
11464 2001-11-03 Akim Demaille <akim@epita.fr>
11466 * doc/autoconf.texi: s/@code/@command/ where appropriate.
11468 2001-11-03 Akim Demaille <akim@epita.fr>
11470 * lib/Autom4te/General.pm: (&catfile, &canonfile)
11471 (&file_name_is_absolute): New, wrappers around routines from
11472 File::Spec.
11473 Use and export them.
11474 (&find_configure_ac): Optionally take a directory where to look at.
11475 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
11476 the arguments.
11477 Default @ARGV to `.', not find_configure_ac.
11478 (&autoreconf): Argument is a directory.
11479 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
11480 * doc/autoconf.texi (autoreconf Invocation): Update.
11482 2001-11-03 Akim Demaille <akim@epita.fr>
11484 * lib/Autom4te/General.pm (@export_vars, @export_subs)
11485 (@export_forward_subs): New.
11486 Add basename, dirname, and fileparse.
11487 (@EXPORT): Adjust.
11488 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
11489 Don't look for aclocal flags if we already know aclocal is not
11490 used.
11491 Move aclocal.m4t only if it exists.
11492 Reported by Ezra Peisach.
11494 2001-11-03 Akim Demaille <akim@epita.fr>
11496 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
11497 passed on command line, defaulting to ./configure.ac if present.
11498 (&maybe_autoreconf, File::Find): Remove, unused.
11499 (&autoreconf): If autoconf is not used, don't try to trace.
11501 2001-11-02 Akim Demaille <akim@epita.fr>
11503 * configure.ac: Bump to 2.52g.
11505 2001-11-02 Akim Demaille <akim@epita.fr>
11507 Version 2.52f.
11509 2001-11-02 Akim Demaille <akim@epita.fr>
11511 * config/config.guess, config/config.sub, doc/standards.texi:
11512 * config/lispdir.m4: Update from masters.
11513 * configure.ac: Bump to 2.52f.
11515 2001-11-02 Akim Demaille <akim@epita.fr>
11517 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
11518 Don't run aclocal when aclocal.m4 is not from aclocal.
11519 From Ezra Peisach.
11520 Don't run libtoolize and gettextize if --install is not given.
11522 2001-11-01 Paul Eggert <eggert@twinsun.com>
11524 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
11525 be invoked before _AS_LINENO_PREPARE.
11526 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
11527 than character ranges.
11529 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
11530 invoking AS_BASENAME. Set the locale variables to 'C' if
11531 possible, as POSIX requires this to get the traditional
11532 behavior.
11533 * doc/autoconf.texi (Special Shell Variables): Describe the above.
11535 2001-10-31 Paul Eggert <eggert@twinsun.com>
11537 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
11538 with {}, as that triggers a bug in Bash 2.05.
11540 (_AS_LINENO_PREPARE): Use Sed rather than
11541 Awk. Fix the sed prepass to work even if there are multiple
11542 instances of $LINENO on the same line. Do not substitute for
11543 other variables like $LINENOT. Do not check file dates; such a
11544 check is unreliable on sufficiently fast machines, and removing
11545 the check makes the code simpler and more reliable. Check for
11546 output and chmod failures.
11548 * doc/autoconf.texi (Special Shell Variables): Document
11549 the above.
11551 2001-10-31 Akim Demaille <akim@epita.fr>
11553 * tests/Makefile.am (atconfig): Remove this target, Automake
11554 handles it now.
11556 2001-10-31 Akim Demaille <akim@epita.fr>
11558 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
11559 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
11560 provided, while it is optional.
11561 * configure.ac: Adjust.
11563 2001-10-26 Paul Eggert <eggert@twinsun.com>
11565 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
11566 lib/Autom4te/Struct.pm:
11567 Require Perl 5.005_03 instead of just 5.005, as some tests fail
11568 with 5.005_02.

11573 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
11574 (_AS_LINENO_PREPARE): Use it instead of shell eval, since

11594 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
11595 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
11596 POSIX decided to standardize on the int flavor of strerror_r.
11597 Always do char* test, as there's no reason not to.
11598 Assign to a char* var, to catch strerror_r that returns int*.
11600 * doc/autoconf.texi (Particular Functions):

11667 (AS_BASENAME_SED): Do not assume GNU sed semantics.
11668 (AS_BASENAME): Use 'basename' if that works; then try 'expr';

11672 contains white space.
11673 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):

11908 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

12051 2001-09-22 Akim Demaille <akim@epita.fr>
12053 Rely on `$LINENO' when possible instead of `__oline__'.
12055 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
12056 `$LINENO' support replacement when not supported.
12057 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
12058 them explicitly to be sure they are not output before this section
12059 (via m4_require). Cosmetic only.
12060 * lib/autoconf/c.m4, lib/autoconf/general.m4,
12061 * lib/autoconf/programs.m4: Replace all the occurrences of
12062 `__oline__' with `$LINENO'.
12063 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
12065 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
12067 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
12068 character (u: -> ue) in a code comment.
12069 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
12070 it works.
12072 2001-09-21 Akim Demaille <akim@epita.fr>
12074 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
12075 Suggested by Jim Meyering.
12077 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12079 * lib/autoconf/programs.m4: Use extensions listed in
12080 $ac_executable_extensions when looking for programs.

12084 * lib/autoconf/general.m4: Fix a small Englisho.

12086 setting up ac_dir_suffix and ac_top_builddir.
12087 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
12089 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

12092 PATH_SEPARATOR.
12093 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
12094 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should

12096 * lib/autotest/general.m4: Replace occurrences of ':' in
12097 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
12099 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12101 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
12102 arguments. Fixed a typo.
12104 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12106 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

12109 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12111 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

12118 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12120 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
12121 already have $file). Set output files to binary mode (helps avoid
12122 CR issues on DOSish systems).
12124 2001-09-19 Akim Demaille <akim@epita.fr>
12126 * lib/autotest/general.m4: Englishoes.
12127 From Tim Van Holder and Alexey Mahotkin.
12129 2001-09-18 Paul Eggert <eggert@twinsun.com>
12131 * doc/autoconf.texi (Common Shell Constructs): New node,
12132 documenting AS_DIRNAME.
12133 (Limitations of Usual Tools): Refer to it when discussing dirname.
12134 Also, update discussion of POSIX standard to reflect latest draft.
12136 * lib/autoconf/c.m4:
12137 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
12139 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
12140 Do not pass a first argument with leading '-'
12141 to expr, by parenthesizing initial integers that might be negative.
12143 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
12144 now merely checks whether it is an error to pass an argument
12145 to getpgrp.
12147 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
12148 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
12149 whether it is a (compile-time) error to pass an argument to
12150 getpgrp. This simpler test supports the revised documentation,
12151 and is all that AC_FUNC_GETPGRP's users really need.
12153 2001-09-18 Akim Demaille <akim@epita.fr>
12155 * doc/autoconf.texi (Limitations of Make) <$<>: New.
12157 2001-09-18 Akim Demaille <akim@epita.fr>

12165 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
12166 correctly.
12167 Add test for AS_BASENAME.
12168 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
12169 added test. It now correctly handles /1/2/3/, returning '3' not ''.
12170 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
12171 * tests/base.at: Fixed the expected responses. The old ones were
12172 one line out...
12173 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
12174 the documentation claims it should (and how it behaved in 2.13).
12176 2001-09-18 Akim Demaille <akim@epita.fr>
12178 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
12179 the AC_CONFIG_COMMANDS invocation.
12180 This also solves the name clash problems.
12181 Don't set the package's ID.
12182 * lib/m4sugar/Makefile.am (version.m4): Revamp.
12183 No longer to be shipped.
12184 (version.in): Remove.
12185 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
12186 * lib/autoconf/status.m4: Adjust.
12187 Use `m4_PACKAGE_STRING'.
12188 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
12189 the only optional argument is the name of the test suite.
12190 Expect `package.m4' to define the package signature.
12191 * lib/autom4te.in (Autotest): Add `package.m4?'.
12192 * tests/Makefile.am (package.m4): New.
12193 * tests/suite.at: ifnames is a victim.
12195 2001-09-18 Akim Demaille <akim@epita.fr>
12197 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
12198 AC_LIBSOURCE, AC_CONFIG_FILES.
12199 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
12200 program version string doesn't match the package's.
12201 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
12202 after `(cached)'.
12204 2001-09-17 Paul Eggert <eggert@twinsun.com>
12206 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12207 Allow expression to return any value that can fit into unsigned long
12208 (not int, as before). Check for output errors.
12210 2001-09-17 Bruno Haible <haible@ilog.fr>
12212 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12213 Always include <stdio.h> and <stdlib.h>. Evaluate
12214 the expression in an extra function before these includes. Call
12215 fprintf "%d" only after ensuring the argument is of type 'int'.
12216 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
12218 2001-09-17 Paul Eggert <eggert@twinsun.com>
12220 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
12221 or CFLAGS=-O5. In that case, the linker has a relaxed view of
12222 fatal errors, and AC_CHECK_LIB causes it to include libraries even
12223 when they don't exist.
12225 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
12226 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
12227 need it.
12229 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
12230 version with the version used by fileutils 4.1, except use
12231 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
12232 we don't need it.
12234 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
12236 2001-09-13 Akim Demaille <akim@epita.fr>
12238 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
12239 _first_.
12240 Reported by Gerrit P. Haase.

12244 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

12264 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
12265 AT_tests_all for consistency.

12268 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
12270 2001-09-13 Akim Demaille <akim@epita.fr>
12272 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
12274 2001-09-13 Akim Demaille <akim@epita.fr>
12276 * lib/autotest/general.m4 (AT_INIT): Create and remove
12277 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
12278 test suites can cohabit.
12280 2001-09-13 Akim Demaille <akim@epita.fr>
12282 * tests/mktests.sh: Don't output banners for empty test files.
12284 2001-09-13 Akim Demaille <akim@epita.fr>
12286 Test suites can be run independently of configure.

12332 2001-09-10 Akim Demaille <akim@epita.fr>
12334 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

12367 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
12368 in addition, it introduces useless differences in logs.
12369 (AT_INIT): Let atconfig and atlocal be both optional.
12370 Adjust PATH computation.

12381 to avoid GCC warnings.
12382 From Uwe Seimet.
12384 2001-09-05 Akim Demaille <akim@epita.fr>
12386 * bin/autom4te.in: --language is -l, not -s.
12388 2001-09-05 Akim Demaille <akim@epita.fr>

12391 the maintainer is dumb enough to do that...
12393 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
12394 excellence in M4 quotation: consider `__file__' is active.

12427 New, extracted from main.
12428 Use IO::File wherever possible.
12429 (input.m4): Be constant, use -I instead of hard coding $tmp.

12431 Don't invoke `_au_disable', since ac was not loaded, but just

12434 2001-08-31 Akim Demaille <akim@epita.fr>

12459 2001-08-31 Akim Demaille <akim@epita.fr>
12461 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
12462 (testsuite Scripts): There is no such thing as `atconfig.in'.
12463 And actually one diagram is missing: test suite runtime.
12465 2001-08-31 Akim Demaille <akim@epita.fr>
12467 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
12468 inverse order.
12470 2001-08-31 Akim Demaille <akim@epita.fr>
12472 * bin/autoupdate.in (@include): `installcheck' revealed the path
12473 to m4sugar was lacking!
12475 2001-08-31 Akim Demaille <akim@epita.fr>
12477 * man/Makefile.am (.x.1): We really have to pass
12478 autom4te_perllibdir.
12480 2001-08-31 Akim Demaille <akim@epita.fr>
12482 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
12483 debug scripts, in particular passing explicitly listed tests to
12484 run is stupid.
12486 2001-08-31 Akim Demaille <akim@epita.fr>
12488 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
12489 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
12490 Use directly autom4te, not autoconf.
12491 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
12493 2001-08-31 Akim Demaille <akim@epita.fr>
12495 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
12496 * bin/autoheader.in (%symbol): Strip arguments of macros.
12498 2001-08-31 Akim Demaille <akim@epita.fr>
12500 * doc/autoconf.texi: Catch up -I, --include changes.
12502 2001-08-31 Akim Demaille <akim@epita.fr>
12504 * bin/autom4te.in (&parse_args): Die on unknown languages.
12505 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
12506 need for autoconf.
12507 Promote --include over --macrodir and other obsolete options.
12509 2001-08-31 Akim Demaille <akim@epita.fr>
12511 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
12512 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
12513 * bin/autom4te.in ($autoconf): Pass --force.
12514 `print $out' doesn't print `$_' but `$out'.
12515 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
12516 (autoheader): Pass --force since the test suite goes too fast for
12517 the time stamps.
12518 Adjust to the new autoheader messages.
12520 2001-08-31 Akim Demaille <akim@epita.fr>
12522 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
12523 Check the completeness of the #template.
12524 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
12525 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
12526 invocation.
12528 2001-08-31 Akim Demaille <akim@epita.fr>
12530 * lib/Autom4te/General.pm (&find_file, &update_file): New.
12531 * bin/autoupdate.in, bin/autoheader.in: Adjust.
12532 Drop AC_MACRODIR dead for real.
12533 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
12534 `autoheader: `config.hin' is created'.
12535 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
12537 2001-08-31 Akim Demaille <akim@epita.fr>
12539 * bin/autoheader.in: Rewrite in Perl.
12540 * tests/autoheader: Adjust.
12542 2001-08-31 Akim Demaille <akim@epita.fr>
12544 * bin/autoconf.in (--include, -I): New option.
12545 Map --localdir, --autoconf-dir onto it.
12546 Forward autom4te's options instead of interpreting them.
12547 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
12548 There is no such envvar since the inception of autom4te.cfg.
12549 * bin/autom4te.in (&parse_args): Uniquify `@include'.
12550 * bin/autoupdate.in: Adjust, and perform more control.
12551 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
12552 * tests/autoconf: Dittowise.
12554 2001-08-31 Akim Demaille <akim@epita.fr>
12556 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
12557 * bin/autom4te.in (&find_file): Support `FILE?' standing for
12558 optionally `FILE'.
12559 Use -e, not -f, since /dev/null for instance is OK.
12560 (&parse_args): Adjust.
12561 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
12563 2001-08-31 Akim Demaille <akim@epita.fr>
12565 * configure.ac: Also find tested executables in bin.
12566 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
12567 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
12568 installed peer executables, only PATH is allowed to resolve it.
12569 Pass `autoconf_dir' via options, not via invisible envvars.
12570 * lib/Autom4te/General.pm (&find_peer): Remove.
12571 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
12572 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
12573 * man/Makefile.am: Let help2man rely on PATH instead of trying to
12574 find the executables for it.
12575 * tests/Makefile.am: Major cleanup. Too lazy to document...
12576 * tests/atlocal.in: Remove all the obscure envvar manipulations.
12577 We only need PERL.
12578 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
12579 indeed related to running the test suite, while passing
12580 --autoconf-dir and others is related to running non installed
12581 Autoconf executables. So don't do that, leave it to...
12582 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
12583 * tests/autoscan: New.
12584 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
12585 refer to library files: rely on --language.
12587 2001-08-29 Akim Demaille <akim@epita.fr>
12589 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
12590 s/--set/--language/.
12592 2001-08-29 Akim Demaille <akim@epita.fr>
12594 * doc/autoconf.texi: Strip the @nodes.
12595 Suggested by Paul Eggert.
12596 (Initializing configure): Typo.
12598 2001-08-29 Akim Demaille <akim@epita.fr>
12600 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
12601 Suggested by Paul Eggert.
12603 2001-08-29 Akim Demaille <akim@epita.fr>
12605 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
12606 download in a tmp dir.
12608 2001-08-29 Akim Demaille <akim@epita.fr>
12610 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
12611 case insensitive OSes out there :(
12612 From Tim Van Holder.
12614 2001-08-29 Akim Demaille <akim@epita.fr>
12616 * lib/autom4te.in: New.
12617 * lib/Makefile.am (edit, autom4te.cfg): New.
12618 * bin/autom4te.in (BEGIN): Simplify.
12619 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
12620 (&load_configuration): New. Use it.
12621 (&parse_args): Support --mode, --set, and --melt.
12622 * bin/autoconf.in: Simplify and adjust.
12623 * tests/Makefile.am (AUTOMAKE): Use --set.
12624 * tests/atlocal.in: Adjust.
12625 * BUGS: distcheck and check are weak.
12627 2001-08-29 Akim Demaille <akim@epita.fr>
12629 * lib/autotest/general.m4: Use
12630 foo=`(command) 2>/dev/null`
12631 not
12632 foo=`command` 2>/dev/null
12633 (at-devnull): Rename as...
12634 (AT-devnull): this.
12635 (--clean): Remove AT-* files too.
12636 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
12637 Reported by Nicolas Joly.
12639 2001-08-28 Akim Demaille <akim@epita.fr>
12641 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
12642 quotes inside single quotes.
12643 Reported by Nicolas Joly.
12645 2001-08-28 Kevin Ryde <user42@zip.com.au>
12647 * doc/autoconf.texi (Function Portability): Mention C right shifts.
12649 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
12651 * lib/autotest/general.m4: Reword some messages.
12652 (AT_INIT): Check for the `times' builtin before using it.
12653 Support test ranges as arguments to the testsuite.
12654 Have -e imply -d as the help text suggested.
12656 2001-08-27 Akim Demaille <akim@epita.fr>
12658 * Makefile.maint: Formatting changes.
12659 (do-po-update, po-update, cvs-update, update): New targets.

12671 * lib/autotest/general.m4 (AT_INIT): Log the command line.
12672 Support `VAR=VAL' as arguments.
12673 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
12674 may be set via the command line.
12676 2001-08-27 Akim Demaille <akim@epita.fr>
12678 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
12679 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
12680 first the build dirs, then the src dirs.

12683 2001-08-27 Akim Demaille <akim@epita.fr>
12685 * lib/autotest/general.m4 (AT_INIT): Output the definition of
12686 at_data_files earlier.
12687 (--clean, -c): New option.
12688 * tests/Makefile.am: Use this option.
12690 2001-08-27 Akim Demaille <akim@epita.fr>
12692 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
12693 `ac_top_builddir' to mimic Automake's vocabulary, which much more
12694 readable.
12695 Adjust callers.
12696 * doc/autoconf.texi (Configuration Actions): Document the vars
12697 available in commands.
12698 Emphasize the risks of collisions in init-cmds.

12702 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
12703 (Initializing configure): this new node.
12705 2001-08-27 Akim Demaille <akim@epita.fr>

12718 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move
12719 to...

12721 * lib/autoconf/general.m4 (AH_OUTPUT, AH_VERBATIM)
12722 (_AH_VERBATIM_OLD, AH_TEMPLATE, _AH_TEMPLATE_OLD, AH_TOP, AH_BOTTOM):

12726 2001-08-27 Akim Demaille <akim@epita.fr>
12728 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
12729 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
12730 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
12731 -> ac_dir).
12732 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
12733 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
12735 2001-08-27 Akim Demaille <akim@epita.fr>
12737 * lib/autoconf/autoconf.m4 (AC_CONFIG_COMMANDS)

12760 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
12761 (AMTAR): Help automake define it.
12762 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
12763 needed, 1.5 can have a macro and a target with the same name.
12764 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
12765 * m4/strip.m4: New.

12778 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
12779 Adjust callers.
12780 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
12781 the name of the directory they're in, instead of the filename,
12782 since version.m4 is now in m4sugar, but m4_acversion must not be
12783 classified as an Autoconf macro.
12784 ($input_m4): Don't qualify the path to m4sugar.
12785 Rather, pass autoconf_dir to m4.
12786 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
12787 * tests/suite.at: Require 2.52c.
12789 2001-08-27 Akim Demaille <akim@epita.fr>

12801 of config.log on traps.
12802 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
12803 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
12804 for config.status'.
12805 Open the log as soon as possible.
12806 Use the same log introduction as configure's.
12808 2001-08-22 Paul Eggert <eggert@twinsun.com>
12810 * doc/autoconf.texi (Indices): New node.
12811 Move indices out of the top level menu and into this submenu.
12813 2001-08-22 Akim Demaille <akim@epita.fr>
12815 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
12816 AC_TRY_COMMAND.
12817 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.
12819 2001-08-22 Akim Demaille <akim@epita.fr>
12821 * lib/autoconf/general.m4 (AC_SHELL_PATH_WALK, AC_CHECK_PROG)

12858 * configure.ac (AT_CONFIG): Fix the path.
12859 * m4/atconfig.m4 (AT_CONFIG): Don't use EOF but ATEOF so that 2.52
12860 can be used.
12862 2001-08-20 Alexandre Duret-Lutz <duret_g@epita.fr>
12864 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
12865 program with AC_LANG_PROGRAM before feeding it to
12866 AC_COMPILE_IFELSE. Cleanup grep usage.
12868 2001-08-20 Akim Demaille <akim@epita.fr>
12870 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
12871 * NEWS, README, README-alpha, TODO, tests/README: This package is
12872 `Autoconf', not `autoconf' (the executable).
12874 2001-08-20 Akim Demaille <akim@epita.fr>
12876 Info readers seem to need `Index' in the index node title :(
12878 * doc/autoconf.texi: Reverse the 2001-08-15 change which
12879 simplified index node names.
12881 2001-08-20 Akim Demaille <akim@epita.fr>
12883 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
12884 arguments are not literals.
12885 * doc/autoconf.texi (Input) <AC_INIT>: Arguments must be literals.
12886 Specify the output variables, and macros defined.
12888 2001-08-20 Akim Demaille <akim@epita.fr>
12890 * doc/autoconf.texi (Examining Declarations) <AC_TRY_CPP>:
12891 (Examining Syntax) <AC_TRY_COMPILE>
12892 (Examining Libraries) <AC_TRY_LINK>
12893 (Test Programs) <AC_TRY_RUN>: These macros double quote some of
12894 their arguments.
12895 Reported by Werner Lemberg.
12897 2001-08-20 Akim Demaille <akim@epita.fr>
12899 * lib/autotest/general.m4 (AT_INIT): Compute top_builddir,
12900 top_srcdir and srcdir from at_topbuild_2_topsrc and at_testdir.

12925 Huh!?!?! There are still some user EOF tags used, which prevents
12926 their use in AC_CONFIG_COMMANDS for instance...
12928 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
12929 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

12992 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

13010 * doc/autoconf.texi: Work around Texinfo buglets.
13011 (Transformation Rules): One example is enough, users are expected
13012 to have their brains on. And BTW, use DESTDIR.
13013 (dvar): New macro. Use it.
13015 2001-08-17 Akim Demaille <akim@epita.fr>
13017 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

13057 value.

13065 (cvs-dist): depends upon it.
13067 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
13069 * tests/Makefile.am: Use a clean-local rule to remove
13070 autom4te.cache (it's a directory, not a file.
13071 * Makefile.am: Ditto (but maintainer-clean-local).
13073 2001-08-15 Akim Demaille <akim@epita.fr>
13075 * bin/autom4te.in (@m4_warning): New.
13076 (&handle_m4): Use it.
13077 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
13078 warnings are issued at each run.
13079 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
13080 is in the src tree.
13082 2001-08-15 Akim Demaille <akim@epita.fr>
13084 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
13085 don't waste time running `autoupdate --version' works.
13086 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
13088 2001-08-13 Akim Demaille <akim@epita.fr>
13090 * doc/autoconf.texi (ma): Rename this index as...

13143 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
13145 * tests/semantics.at (AC_C_BIGENDIAN): New test.
13147 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
13149 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
13150 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
13151 * doc/autoconf.texi (C Compiler Characteristics): Update
13152 documentation for AC_C_BIGENDIAN.
13154 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
13156 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
13157 magic values from an object file when cross-compiling.
13158 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
13160 2001-08-10 Akim Demaille <akim@epita.fr>
13162 * bin/autom4te.in (&handle_output): Don't use `grep' with side
13163 effects.
13164 Suggested by Russ Allbery.
13166 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
13168 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
13169 current $prefix to the sub-configures.
13171 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
13173 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
13174 extension (needed on BeOS). Reported by Guido van Rossum.
13176 2001-08-09 Akim Demaille <akim@epita.fr>
13178 * bin/autom4te.in ($icache): Load it only if older than autom4te.
13180 2001-08-07 Akim Demaille <akim@epita.fr>
13182 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
13183 removed.
13184 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
13185 No need to remove the files before and after the each test, before
13186 each test and at the end of the suite is enough.
13187 Display only the children `times', not the shell's.
13188 If the test failed or was skipped, at-times is not available.
13190 2001-08-07 Akim Demaille <akim@epita.fr>
13192 Always produce testsuite.log, including when there are no
13193 failures. This helps getting information on skipped tests, and
13194 duration of the tests. Err, implement the latter btw.
13196 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
13197 Dump information on the first run of each test.
13198 (AT_CLEANUP): Create `at-times' containing the duration of the
13199 test group.
13201 2001-08-07 Akim Demaille <akim@epita.fr>
13203 The use of `dumpstat' revealed that `len' was used although it
13204 should not. m4_text_wrap was using it, but in the Autoconf world
13205 where it is legal. Hence (i) test M4sh in its own world, not
13206 Autoconf's, and (ii), ahem, fix the bug :)
13208 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
13209 does not like `' instead of [].
13210 (AT_INIT): Forbid `^_?AT_'.
13211 And don't output such tokens.
13212 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
13213 `script.as', and `autom4te.cache'.
13214 Remove `empty' and `macro' which are no longer used.
13215 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
13216 * tests/m4sugar.at: Use it.
13217 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
13219 2001-08-07 Akim Demaille <akim@epita.fr>
13221 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
13223 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
13225 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
13227 2001-08-04 Akim Demaille <akim@epita.fr>
13229 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
13230 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
13231 AC_TRY_LINK.
13232 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
13233 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
13234 (AC_F77_MAIN): Likewise.
13236 2001-08-04 Akim Demaille <akim@epita.fr>
13238 Don't rely on M4sugar outputting the patterns in files, since we
13239 might process the output _without_ running m4, hence without these
13240 files.
13242 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
13243 * bin/autom4te.in (@Request::includes): Remove, unused.
13244 (@Request::source): Rename as...
13245 (@Request::input): this.
13246 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
13247 (&handle_output): Fetch the patterns from the traces.
13248 `$forbidden' and `$allowed' are constant: use m//o.
13249 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
13250 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
13252 2001-08-04 Akim Demaille <akim@epita.fr>
13254 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
13255 autoconf', i.e., in addition to caching traces, cache the output.
13257 * bin/autom4te.in (Request::cache): Rename as...
13258 (Request::id): this.
13259 ($cache, $icache, $tcache, $ocache): New.
13260 (&handle_m4): Save M4 output in the cache instead of $tmp.
13261 (&handle_output): Adjust.
13262 (&up_to_date_p): Check that the output cache is up to date too.
13263 (top level): Run `&handle_m4' iff force or the cache is invalid.
13264 Run `&handle_output' if the output cache is more recent.
13266 2001-08-04 Akim Demaille <akim@epita.fr>
13268 * bin/autom4te.in ($force): New.
13269 (&parse_args, &print_usage): -f, --force is a new option.
13270 (&handle_output): CPP directives might have spaces after `#'.
13271 (&parse_args): The first file only can be frozen.
13273 2001-08-04 Akim Demaille <akim@epita.fr>
13275 Don't let autom4te compute the `include' traces several times:
13276 first check that the trace cache file is up to date, and then
13277 compare its timestamp with that of the output.
13279 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
13280 the preamble. Don't require 5.005 as Autom4te::General does it,
13281 and better yet (use `use', not `require'!).
13282 * lib/Autom4te/Struct.pm: Rename the last occurrences of
13283 Class::Struct as Autom4te::Struct.
13284 * lib/Autom4te/General.pm (File::stat): Use it.
13285 (&mtime): New, export it.
13286 * bin/autom4te.in: Use it.
13287 Declare `$req' is invalid if it is outdated.
13288 Don't declare it valid before saving it if something went wrong.
13290 2001-08-04 Akim Demaille <akim@epita.fr>
13292 Autom4te shall not encode Autoconf data, and preselecting traces
13293 must be proposed to the users.
13295 * bin/autom4te.in (@required_trace): Remove.
13296 (@preselect): New.
13297 (&parse_args, &print_usage): -p, --preselect is a new option.
13298 (&up_to_date_p): Adjust.
13299 * bin/autoconf.in: Preselect some Autoconf macros.
13301 2001-08-04 Akim Demaille <akim@epita.fr>
13303 * tests/tools.at (autoconf --trace: user macros): Check traces on
13304 macros invoked without arguments, and macros invoked with multiple
13305 lines arguments.
13307 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
13309 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
13310 arguments.
13312 2001-08-03 Akim Demaille <akim@epita.fr>
13314 * bin/autoconf.in ($@): Work around the usual sh bug.
13315 From Nicolas Joly.
13317 2001-08-03 Akim Demaille <akim@epita.fr>
13319 Clean up the handling of the M4 builtins tracing exception.
13321 * bin/autom4te.in (Request::request): Don't complete M4 builtins
13322 trace requests.
13323 (@m4_builtins): Rename as...
13324 (@m4_builtin): this.
13325 (%m4_builtin_alternate_name): New.
13326 (&parse_args): Complete the trace requests with alternate names.
13327 (&handle_traces): Hence no longer do it here.
13328 (&trace_requests): Remove, unused.
13330 2001-08-03 Akim Demaille <akim@epita.fr>
13332 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
13333 m4_if, and m4_wrap.
13335 2001-08-03 Akim Demaille <akim@epita.fr>
13337 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
13338 (m4_divert_pop): Dump the whole diversion stack when a diversion
13339 mismatch happens.
13340 * bin/autom4te.in (&handle_output): Remember of the first
13341 occurrence of a possibly undefined macro, not the last.
13342 Complain about the possibly undefined macros in the same order as
13343 the appear in the output.
13344 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
13345 * tests/tools.at (autoconf: forbidden tokens, basic)
13346 (autoconf: forbidden tokens, exceptions): No longer sort
13347 autoconf's stderr, as it is now deterministic.
13348 Check that `dnl' is caught.
13350 2001-08-01 Akim Demaille <akim@epita.fr>
13352 * configure.ac: Bump to 2.52c.
13354 2001-08-01 Akim Demaille <akim@epita.fr>
13356 Version 2.52b.
13358 * lib/Autom4te/Makefile.am (perllibdir): s/Autoconf/Autom4te/.

13364 2001-08-01 Akim Demaille <akim@epita.fr>
13366 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and

13764 compiler, not the preprocessor.
13765 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): No longer use

13767 the right thing.
13768 * Makefile.am (.m4.m4f): Emphasize M4 error messages and fail

13771 2001-07-03 Akim Demaille <akim@epita.fr>

13800 * aclang.m4 (AC_F77_DUMMY_MAIN): New macro to detect whether a
13801 dummy alternate main is required even if the user provides her own
13802 'main'.

13804 provide an alternate 'main' function name, using the 'main' from
13805 the Fortran libraries.
13806 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
13807 cross-language link tests can be performed successfully.
13808 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
13809 after $LIBS, for consistency; this should be the general rule since

13813 2001-06-29 Pavel Roskin <proski@gnu.org>
13815 * atgeneral.m4 (AT_CHECK): Add a newline to the end of
13816 at-stdout and at-stderr instead of removing the newline
13817 from the echo output, which is not guaranteed to work.
13819 2001-06-28 Jens Petersen <petersen@redhat.com>
13821 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to
