991 The test suite did not cover this bug because the code was not
992 quoting properly the arguments of `rm -f' (which "fails" silently)
993 as well as the arguments of `diff' (whose output was redirected to
994 /dev/null so we couldn't see its error message).
995 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
996 file names passed to `rm' and `diff'.
997 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
998 Add a regression test.

1119 * tests/autotest.at (Choosing where testsuite is run): New test
1120 for this feature.
1121 (Keywords and ranges): Add test for missing -k argument.
1122 * NEWS: Document this.
1123 * doc/autoconf.texi (testsuite Invocation): Likewise.

1138 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1140 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1141 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1142 mode, we change to the source directory, also set $ac_pwd so we
1143 do not go back to the build tree for the next config subdir.

1145 config subdirs on the top level.
1147 Fix parallel `maintainer-check'.

1211 (m4_require): Avoid extra macro calls.
1213 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1215 * tests/torture.at (srcdir): Fix quoting.
1217 Do not pass top_srcdir to configure scripts in testsuite.
1218 * tests/autotest.at (srcdir propagation): Copy install-sh to
1219 source tree.
1220 (my only test): Drop setting of `top_srcdir'.
1221 * tests/base.at (Input/Output): Likewise.
1222 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1223 config.guess, and config.sub to test source tree.

1235 Quote $abs_top_srcdir in tests.
1236 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
1237 * tests/tools.at (Syntax of the shell scripts): Likewise.
1239 * tests/m4sh.at (LINENO): Quote $0.
1241 Fix testsuite program wrapper for whitespace in `pwd`.
1242 The problem here is that the usual mantra is that command
1243 variables can contain arguments, thus we cannot just escape
1244 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1245 $top_builddir/tests directory early in $PATH, so that the
1246 wrappers are found by their plain name.
1247 * tests/wrapper.as: Put $testdir early in $PATH.
1248 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1250 Proper config.status --file/--header and $srcdir escaping.
1251 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
1252 characters in $ac_file_inputs.

1261 Quote $at_group_dir.
1262 * tests/autotest.at (whitespace in absolute testdir): New test.
1264 * lib/autom4te.in: Quote @datadir@.
1266 Proper file name escaping in Autoconf programs and Perl modules.
1267 This includes escaping of characters special to the shell
1268 as well as special to Perl, e.g., leading `<' or `>'.
1269 For example, when $file starts with `>', `open ">$file"'
1270 wrongly tries to append to a different file.
1271 * bin/autoconf.as: Fix quoting for autom4te options.
1272 * lib/Autom4te/General.pm (shell_quote): New function, taken
1273 from coreutils, written by Jim Meyering.
1274 (mktmpdir): Use it.

1278 * bin/autoscan.in (main): Likewise.
1279 * bin/autoupdate.in (main): Likewise.
1280 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
1281 * bin/ifnames.in: Likewise, XFile usage fixes.
1282 * tests/tools.at (autom4te and whitespace in file names): Extend
1283 test. Test twice, with special characters allowed on w32, and the
1284 rest. Test leading and trailing whitespace, for `open_quote'.
1285 (autotools and whitespace in file names): New, analogous test.
1286 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1287 by Russ Allbery and Eric Blake.

1292 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1293 (update_file, contents): Use it.
1295 * Makefile.am (autom4te-update): Rewrite for git.
1297 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1299 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.

1311 When using older automake, don't downgrade build-aux/texinfo.tex.
1312 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1313 * doc/Makefile.am (TEXINFO_TEX): Add.
1315 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1317 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1318 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1319 #undef as this runs afoul of our new way of creating config.h.
1320 Problem reported by Jim Meyering in
1321 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

1325 Fix autom4te for unusual characters in input file names.
1326 * bin/autom4te.in (files_to_options): Quote active characters

1334 2007-11-24 Stepan Kasal <kasal@ucw.cz>

1337 `#AT_STOP_...' line at the end of each test.
1339 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1341 * lib/autotest/general.m4 (AT_INIT): For awk line number
1342 extraction script, ensure `$at_group' has a defined value
1343 even for the empty set, and properly quote its usage inside
1344 the awk script.
1346 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1348 * doc/autoconf.texi (Shell Functions): New chapter. Document
1349 IRIX sh $0 issue in functions, move content from ...
1350 (Portable Shell): ... here.
1351 (Shell Script Compiler): Note that shell functions are not
1352 totally unportable any more.

1365 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1367 Fix IRIX testsuite debugging failures: $0 in functions.
1368 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1369 Do not use $0 inside a function, as IRIX sh will set that to the
1370 function name rather than the script invocation name.
1372 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1373 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1375 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1376 to extract test scripts.
1377 (AT_INIT): Extract and cache test script line numbers.
1379 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1381 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1382 subsequent fixups; the awk -> here-document conversion trashes
1383 performance too much with AIX sh.
1385 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1387 * tests/local.at: Do not test m4, perl with AT_TESTED.
1389 Diagnose and guard against write errors dealing with config.status.
1390 The general idea is this: all write failures from `configure'
1391 writing `config.status' are indicated by $ac_write_error, which
1392 is only checked at the end. This is safe because config.status
1393 code is not executed before the file is complete. Other write
1394 failures, be they inside config.status, or in sub shell/awk
1395 scripts spawned from configure or config.status, typically need
1396 earlier checking, as their results are used right afterwards.
1397 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1398 before writing config.status, check afterwards.
1399 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1400 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1401 Set `ac_write_error' for write failures to config.status. Barf
1402 upon write failures to temporary files.
1403 Adjust note about closing and reopening the here-document.
1404 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1405 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1406 reopening the here-document.
1407 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1408 Ensure `ac_write_error' does not escape into config.status.
1409 Also, add a couple of code paths not yet exercised in the test
1410 suite: a config file with input from stdin, and a config header
1411 output to stdout.
1412 Suggestion for catching write errors by Bruno Haible.
1414 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1416 Avoid error with Tru64 awk and testsuite lines with many words.
1417 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1418 reads the testsuite, set the field separator to an unusual value,
1419 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1420 even splits the input if $i, i>0, was never accessed in the script.
1422 Revert 2007-10-17 change.
1423 * TODO: Multiline args in config files and headers mean something
1424 different and are not fixed, see

1469 Shell functions and variables may share a namespace.
1470 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
1471 limitation.
1473 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
1475 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
1476 gnulib.
1478 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1480 * lib/autoconf/status.m4: Fix a couple of comment typos.
1482 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1484 2007-11-13 Jim Meyering <meyering@redhat.com>
1486 Clean up the rule to create "expr".
1487 * tests/Makefile.am (expr): Don't redirect directly to target.
1488 Redirect just once, not for each echo statement.
1489 Use $@, not literal "expr".
1491 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1493 Don't worry about preprocessor when testing long long.
1494 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1495 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1496 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1497 These no longer check for preprocessor flaws.
1498 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1499 Do not check for preprocessor flaws.
1501 2007-11-13 Jim Meyering <meyering@redhat.com>
1503 Adapt dependencies, now that a version change doesn't modify configure.ac
1504 * GNUmakefile: Remove "make clean" kludge.
1505 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1506 configure.ac.
1507 Don't redirect directly to target.
1508 Use $@, not literal "version.m4".
1510 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1512 * doc/autoconf.texi (Making testsuite Scripts): Document
1513 ":;{" shorthand as in previous patch.
1515 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1517 * doc/autoconf.texi (Limitations of Builtins): Document problem
1518 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1519 for the workaround.
1520 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1521 Use ":;{" shorthand.
1522 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1524 2007-11-12 Jim Meyering <meyering@redhat.com>
1526 Add more non-srcdir build support.
1527 * GNUmakefile (dummy): Split a long line.
1528 Add -v option to autoreconf invocation.
1530 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1531 * GNUmakefile (dummy): Remove INSTALL.
1533 Remove racy commands to build scripts in bin/ and tests/.
1534 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1535 are guaranteed to be built, remove the rules that tried to build
1536 them. Before, with a parallel build, these rules could lead to
1537 two processes writing tests/wrapper.in concurrently.
1539 Build in man/ only *after* building in bin/ and tests/.
1540 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1541 in both bin/ and tests/.
1543 Accommodate non-srcdir build-from-checkout.
1544 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1545 Use git's --git-dir=$srcdir/.git option.
1546 Add quotes, in case tarball_version_file contains shell meta-characters.
1547 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1548 * configure.ac: Pass "." to git-version-gen.
1550 Avoid spurious test failures due to version skew.
1551 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
1553 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1555 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
1556 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
1557 Remove conftest.dSYM directory.
1558 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1559 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
1560 Remove `conftest.*' recursively.
1561 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
1562 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1563 Likewise.
1564 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
1565 * THANKS: Update.
1566 Report and analysis by Jeff Squyres and Peter O'Gorman.
1568 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
1570 Fix typos in variable names.
1571 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
1573 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
1575 Document that $((expression)) is not portable.
1576 * doc/autoconf.texi (Shell Substitutions): Here.
1578 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1580 Ignore configure --help* errors due to LINENO-impaired shells.
1581 * tests/torture.at (Configuring subdirectories, Deep Package):
1582 In the --help* tests in read-only trees, make `.' temporarily
1583 writable again for the `stderr' file, and ignore errors due to
1584 the attempt to write configure.lineno.
1585 Report by Patrick Welche.
1587 2007-11-10 Jim Meyering <meyering@redhat.com>
1589 Generate package.m4 in build-dir, not srcdir.
1590 * tests/Makefile.am (package.m4): Adjust target.
1591 Don't redirect directly to $@.
1592 (CLEANFILES): Add package.m4.
1593 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1594 in $(srcdir).
1595 When running $(AUTOTEST), search "." before searching $(srcdir).
1597 Avoid a race condition that would make parallel "distclean" fail.
1598 * tests/Makefile.am (distclean-generic): Replace the default,
1599 automake-provided rule with an identical one, but with an additional
1600 dependency on distclean-local. Simply adding the dependency would
1601 cause automake not to emit the rule at all.
1602 * BUGS: Building with -jN works, now.
1604 Distribute git-version-gen.
1605 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1606 since GNUmakefile is distributed, and requires it for dist* rules.
1608 Remove two more generated files from version control.
1609 * INSTALL: Remove generated file.
1610 * lib/autoscan/autoscan.list: Remove generated file.
1612 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1614 * GNUmakefile (PATH): Remove stray apostrophes; they become
1615 part of PATH, which isn't wanted here.
1617 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1619 New config files output variable `top_build_prefix'.
1620 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1621 `top_build_prefix'.
1622 * doc/autoconf.texi (Preset Output Variables): Document it.
1623 * NEWS: Update.
1624 Report by Bob Friesenhahn.
1626 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1627 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1628 function, to parametrize arithmetic with expr vs. the shell.
1629 Use it where possible.
1630 Suggestion by Benoit Sigoure.
1632 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1634 Adjust the documentation of autotest WRT atlocal.
1635 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1636 when using Automake, to write a rule to produce atlocal, since it's
1637 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1638 distributed, not atconfig.in.
1640 2007-11-04 Eric Blake <ebb9@byu.net>
1642 Update list information.
1643 * README: Mention new autoconf-commit list.
1644 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
1646 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1648 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
1650 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
1652 * build-aux/.gitignore: Ignore mkinstalldirs.
1654 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
1656 2007-11-03 Jim Meyering <meyering@redhat.com>
1658 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1659 * build-aux/git-version-gen: This syncs from coreutils.
1661 Adjust the build procedure so "make check" works reliably.
1662 * README-hacking: Include an extra step between "make" and
1663 "make check" to ensure that the latter passes.
1665 Use just-built tools, when possible.
1666 * GNUmakefile (PATH): Set and export here, ...
1667 (dummy): ... rather than here.
1669 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1670 and Andreas Schwab <schwab@suse.de>
1672 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
1673 exit status bug.
1675 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1677 * configure.ac (AC_PREREQ): Require version 2.60, for
1678 AC_PROG_SED, AC_PROG_GREP.
1680 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
1681 and Jim Meyering <meyering@redhat.com>
1682 and Andreas Schwab <schwab@suse.de>
1683 and Eric Blake <ebb9@byu.net>
1685 Document a bug in GNU Bash with compound commands and redirections.
1686 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
1687 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
1688 workaround.
1690 2007-11-03 Eric Blake <ebb9@byu.net>
1692 Support m4 1.4.5 in testsuite.
1693 * tests/torture.at (Define a newline): Exclude line numbers in
1694 error message.
1695 Reported by Ralf Wildenhues.
1697 2007-11-03 Jim Meyering <meyering@redhat.com>
1699 Remove automake-provided files from version control.

1702 * build-aux/missing: Remove file.
1703 * build-aux/mdate-sh: Remove file.
1704 * build-aux/.gitignore: New file.
1705 Suggestion from Ralf Wildenhues.
1707 2007-11-03 Eric Blake <ebb9@byu.net>
1709 Adjust version comparison to account for git snapshot numbers.
1710 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
1711 component separator.
1712 * doc/autoconf.texi (Number processing Macros)
1713 <m4_version_compare>: Document this change.
1714 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
1716 2007-10-30 Bruno Haible <bruno@clisp.org>
1718 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
1719 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
1720 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
1721 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
1722 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
1723 Suggested by Paul Eggert.
1725 2007-10-28 Jim Meyering <meyering@redhat.com>
1727 * README-hacking: Autoconf, Automake, and Perl are required to build.
1728 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
1730 2007-10-28 Jim Meyering <meyering@redhat.com>
1732 README-hacking: Recommend running autoreconf -vi.
1733 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
1734 so that we use just-built tools when they're available.
1735 Suggestions from Ralf Wildenhues.
1737 2007-10-28 Jim Meyering <meyering@redhat.com>
1739 Make inter-release --version output more useful.
1741 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1742 which indicates that it is built using the 19th change set
1743 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1744 is a prefix of the commit SHA1.
1745 * build-aux/git-version-gen: New file.
1746 * configure.ac: Run it to set the version.
1747 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1748 * Makefile.am (dist-hook): Arrange so that .version appears only
1749 in distribution tarballs, never in a checked-out repository.
1750 * .gitignore: Add .version here, too. Just in case.
1751 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1752 not configure.ac, now that the version number changes automatically.
1754 Ensure that $(VERSION) is up to date for dist-related targets.
1755 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1756 git-version-gen doesn't match $(VERSION), but only for dist targets.
1758 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1760 Fix `Deep Package' failure with a configure script early in PATH

1790 problem reported by Bruno Haible in
1791 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
1793 2007-10-22 Eric Blake <ebb9@byu.net>
1795 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
1796 preprocessor.
1798 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
1800 Don't check for bug in HP-UX 11.00 cpp.
1801 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
1802 Use -1ull rather than -1u, since that causes problems with gnulib; see
1803 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
1805 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1821 escaping of backslash in here-documents.
1823 Fix `Deep Package' test failure on FreeBSD.
1824 * tests/torture.at (Deep Package): Do not add `.' to $PATH
1825 unnecessarily. Do not try running `/bin/sh configure' with a
1826 configure script to be found in $PATH, if the shell does not do
1827 this resolution. Fixes test failure on FreeBSD.
1829 Fix config header generation with AIX awk.
1830 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
1831 script, use helper array D_is_set, as `" 0"' does not evaluate

1869 * lib/autotest/general.m4 (BANNERS): New named diversion.
1870 (TESTS_END): Diversion no longer used.
1871 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a

1873 array of banner text from a special diversion.
1874 <PARSE_ARGS_END>: No longer need awk to find banners.
1875 <TESTS>: Banners are no longer processed by main driver loop, so
1876 we no longer need case statement.
1877 (AT_BANNER): Rewrite to populate new diversion.
1878 (AT_SETUP): Each test invokes its own banner. No output is needed
1879 to the TESTS diversion.
1880 * doc/autoconf.texi (Writing Testsuites): Document slight
1881 semantics change.

1928 (TEST_GROUPS): ...to this.
1930 Reject FreeBSD m4.

2905 2007-05-21 Paul Eggert <eggert@cs.ucla.edu>
2907 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp
2908 choice, since that's what we do with --enable-largefile etc.
2909 Redo indenting and assignments to simplify things a bit, and make
2910 the parens work with Emacs.
2912 * doc/autoconf.texi (Generic Compiler Characteristics): Fix typo
2913 in my previous change: AC_C_OPENMP -> AC_OPENMP. Reported by Bruno

2991 section titles and other comments; no code change.
2993 2007-05-01 Kevin Ryde <user42@zip.com.au>
2995 * doc/autoconf.texi (Particular Programs): Typo
2996 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
2998 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
3000 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
3001 'configure' will fail if the shell lacks proper support for shell
3002 functions. Suggested by RMS.
3004 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
3006 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
3007 about Solaris /bin/printf '%010000x' 123. Problem reported by
3008 Bruno Haible.
3010 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
3012 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
3013 for a.* when searching for executables, as this prevents users
3014 from having files like a.c. Problem reported by Ralf Wildenhues in:
3015 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
3016 This fixes a problem introduced on 2000-12-19.

3026 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
3027 AC_CHECK_TYPE, AC_CHECK_TYPES.
3028 * doc/autoconf.texi (Generic types): C types must be type-names
3029 (the C terminology), not type-ids (the C++ term). C++ types
3030 must not be anonymous.
3031 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
3032 for C++; this drops support for anonymous struct and union types,
3033 which were problematic anyway.
3034 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
3035 for C++.
3037 2007-04-12 Jim Meyering <jim@meyering.net>

3050 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
3051 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
3052 with objects too. Document the restrictions on its use.
3053 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3054 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3055 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3056 works but the latter doesn't, then it's a valid type.
3057 This lets people use function types and so forth.
3058 For C++ there doesn't seem to be a simple solution, so leave it alone.
3059 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3060 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3061 AC_CHECK_TYPE; that wasn't documented or necessary.
3063 2007-04-11 Stepan Kasal <kasal@ucw.cz>
3065 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

3084 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
3086 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
3087 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
3088 default still has the problem. Problem reported by Bruce Korb.

3108 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
3109 checks for unsigned long long int.
3111 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
3113 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
3114 nonstandard grep R.E. escape sequences.
3116 2007-03-17 Jim Meyering <jim@meyering.net>
3118 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
3119 (Limitations of Usual Tools): Also list \< and \>, and mention that
3120 HP-UX's grep, like the one from Solaris, does not support that syntax.
3122 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3124 * doc/autoconf.texi (Specifying Names): `--host' does not
3125 change the build type.
3127 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
3129 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN

3140 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
3141 universal binaries. Problem reported by Elias Pipping.
3143 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
3145 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.

3163 status of rm so we know when it failed.
3164 If cleaning of test dir failed before running the test, warn.
3165 Output the line separator in verbose mode before the warning
3166 to make clear the warning belongs to the following test.
3168 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>

3183 carriage return.
3184 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
3185 with traditional Awk and begin.
3186 * tests/torture.at (Limitations of Builtins): Document the problem

3191 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
3193 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
3194 input from /dev/null in awk test, so even Solaris /usr/bin/awk
3195 will not wait for input with a script containing only a BEGIN
3196 rule.
3198 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
3200 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version

3220 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
3222 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
3223 latest version.
3224 (Shell Substitutions): Note problems with @{var:=value} etc.
3225 Add a new section for problems with @{#var} etc. Problem noted

3229 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3231 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3232 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3233 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3234 substitution will still be done by the special code.
3235 Report by Jim Meyering.
3237 * doc/autoconf.texi (File System Conventions): Mention that
3238 $PATH_SEPARATOR is for the build system only.

3256 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3258 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3259 early on the reader side, drop stderr of the input to avoid
3260 `broken pipe' error output; this may happen even with shell
3261 builtin `echo' of some bash versions. Reports by Ian Macdonald
3262 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3264 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3276 Fix some wording problems noted by Paolo Bonzini in:
3277 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3278 * doc/autoconf.texi (Signed Overflow Examples): Give more
3279 discussion about the allow_superuser_privileges example,
3280 and change it a bit to make things clearer.
3281 (Optimization and Wraparound): Clarify whether the compiler
3282 will generate an infinite loop for the example derived from
3283 Autoconf's mktime test.
3284 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3285 Also, clarify unsigned multiplication overflow.
3287 2007-01-04 Eric Blake <ebb9@byu.net>
3289 * bin/Makefile.am (RELEASE_YEAR): New macro.
3290 (edit): Use it to supply correct copyright year to scripts.
3291 * bin/autoconf.as (version): Use it.
3292 * bin/autoheader.in ($version): Likewise.
3293 * bin/autom4te.in ($version): Likewise.

3295 * bin/autoscan.in ($version): Likewise.
3296 * bin/autoupdate.in ($version): Likewise.
3297 * bin/ifnames.in ($version): Likewise.
3299 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3301 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3302 feedback. The most important changes document what happens when
3303 you convert an out-of-range value to a signed integer type, and
3304 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3305 a + b.
3307 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3308 rewrite, taking notions from the recent discussion on the gcc and
3309 autoconf mailing lists; please see
3310 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3311 and follow the many links.
3312 (Integer Overflow Basics, Signed Overflow Examples):
3313 (Optimization and Wraparound, Signed Overflow Advice):
3314 (Signed Integer Division): New sections.
3316 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3318 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3319 preprocessor macro arguments in traced name.
3320 * doc/autoconf.texi (Defining symbols): Document longstanding
3321 support for AC_DEFINE-ing macros with arguments, and document
3322 behavior when the same variable has multiple AC_DEFINEs.
3323 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3324 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3325 macros directly, giving much shorter and simpler code.
3327 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3329 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3330 space before "$ac_configure_args" to prevent a 'config.status
3331 --recheck' failure if ac_configure_args doesn't contain a leading
3332 space. This works around a problem with the XEmacs configure.ac,
3333 which uses the (undocumented) ac_configure_args variable
3334 inconsistently with Autoconf.
3336 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3338 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3339 Include <limits.h>, and use its INT_MAX to rewrite the
3340 j loop so that it does not overflow 'int'. Problem reported by
3341 Ralf Wildenhues in
3342 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3343 Play it safe by shifting left by 1 rather than multiplying by 2,
3344 as GCC is less likely to optimize this away when the value
3345 is signed (when it assumes overflow leads to undefined behavior).
3346 Also, don't assume time_t uses two's complement.
3348 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3350 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3351 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3352 dumps core on it. Report by Tim Rice.
3354 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3356 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3357 --disable-option-checking to --help output even when
3358 AC_PRESERVE_HELP_ORDER is not used.
3359 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3360 --with argument, rather than argument with [-.] replaced by
3361 underscores.
3362 * NEWS: Fix typo in previous change; the news was in the
3363 wrong section.
3365 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3367 * NEWS: Warnings are now generated by default for unknown
3368 --enable-* and --with-* options.
3369 * doc/autoconf.texi (Option Checking): Renamed from
3370 (Configure Option Checking). Tighten up the wording a bit.
3371 (External Software, Package Options): Cross-reference to Option
3372 Checking, and use this to shorten our section.
3373 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3374 "$x" to test "x$foo" != x.
3375 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3376 Don't warn if $enable_option_checking is "no".
3377 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3378 ac_unrecognized_opts to the empty string.
3379 Don't echo the unrecognized opts, as this might mishandle
3380 backslashes or leading -.
3381 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3382 usage next to the other --disable-FEATURE options in the
3383 help string.
3385 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3387 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3388 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3389 Print warning for unrecognized --with and --enable options
3390 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3391 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3392 Disable option checking when subdirs are configured.
3393 (AC_OUTPUT): If warnings are enabled, print warning about
3394 unrecognized --with and --enable options at the end of
3395 the configure output (as well as at the beginning).
3396 * doc/autoconf.texi (Option Checking): New node.
3397 Document new option warning functionality.
3399 2006-12-16 Eric Blake <ebb9@byu.net>
3401 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3402 * NEWS: Start news for current version.
3404 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3406 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3407 Define HAVE_GETMNTENT to 1, not to the empty string.
3408 Problem originally reported by Jochen Friedrich in
3409 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3411 This change prompted by a problem report by Andrey Simonenko in
3412 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3413 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3414 object-like macros only, in the traditional portable character
3415 set.
3416 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3417 Warn about attempts to define things that are not identifiers.
3418 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3419 awful hack that AC_DEFINEd macro names containing parentheses.
3421 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3423 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3424 too drastic, even if Texinfo in theory requires it for info mode.
3426 (config.status Invocation): Renamed back from Recreating a
3427 Configuration).
3428 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3429 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3431 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3433 * NEWS: Version 2.61a.
3435 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3436 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3438 * NEWS: Document changes with echo and printf, and the lack
3439 of limits on the total size of multi-line values of substituted
3440 variables, and the AC_FUNC_FSEEKO fix.
3442 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3444 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3445 Writing configure.ac.
3446 (Autoconf Input Layout): Renamed from configure.ac Layout.
3447 (Recreating a Configuration): Renamed from config.status Invocation.
3448 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3449 (acconfig Header): Renamed from acconfig.h.
3450 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3451 (Writing Testsuites): Renamed from Writing testsuite.at.
3452 (Autom4te Cache): Renamed from autom4te.cache.
3454 * BUGS: Remove mention of VPATH problem, since it's now documented
3455 not to be a bug in the Autoconf build procedure itself, but rather
3456 a problem with the proprietary `make' programs.
3458 * doc/autoconf.texi (Build Directories): Add a cross reference
3459 to VPATH and Make.
3461 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3462 * doc/standards.texi: Sync from gnulib.
3464 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3465 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3466 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3467 generated automatically.
3469 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3471 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3472 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3473 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3475 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3477 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3478 `CEOF$ac_eof' special marker, the awk script cannot contain a
3479 line matching `^CEOF', so this is not needed any more.
3480 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3481 special marker in the test.
3483 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3485 * tests/tools.at (autom4te preselections): Use `find -newer';
3486 remove one of the sleeps.
3488 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3489 more readable, using ...
3490 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3492 * doc/autoconf.texi (autoheader Invocation): Do not double-
3493 quote the parameter of `AH_BOTTOM' in the example.
3495 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3497 * doc/autoconf.texi (Configuration Headers): Remove the
3498 example with multiple input files.
3499 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3500 multiple input files.
3502 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3504 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3505 creating the awk substitution script, handle one input line at a
3506 time, so that the maximum length of a substituted (multi-line)
3507 value is not limited by the size of the sed pattern space.
3508 The trade-off is a slightly repetitive sed script.
3509 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3510 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3511 * tests/torture.at (Substitute a 2000-byte string): Increase the
3512 test with several long lines, they should not be caught by sed
3513 limits any more.
3515 * tests/tools.at (autom4te preselections): New test, to flag
3516 entries missing from autom4te.cfg.
3517 Report by David Byron <dbyron@hheld.com>.
3519 * tests/torture.at (Substitute a 2000-byte string): Actually use
3520 AC_PROG_AWK, so the last change works as intended.
3521 (Substitute and define special characters): Likewise.
3522 (Substitute a newline): Likewise.
3524 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3525 instead of `awk' consistently.
3526 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3527 * tests/torture.at (Torturing config.status): Test both the
3528 result of AC_PROG_AWK and plain awk.
3529 (Substitute a 2000-byte string): Likewise.
3530 (Substitute and define special characters): Likewise.
3531 (Substitute a newline): Likewise.
3533 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3535 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3536 can be assigned to a function pointer. Problem reported by
3537 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3538 part of a patch by Ralf Wildenhues in that same bug report.
3540 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3542 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3543 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3545 2006-12-01 Eric Blake <ebb9@byu.net>
3547 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3548 cross-compiling from cygwin to mingw.
3549 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3550 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3551 to lib/autoconf/c.m4.
3553 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3555 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3556 string for more reliable failure. Wrap the entire test that
3557 causes the broken Solaris printf to dump core, in a subshell,
3558 so the segmentation fault message is reliably suppressed.
3559 Fix shell expansion errors by using /usr/ucb/echo always;
3560 avoid an error on systems without it by another subshell.
3561 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3562 subshell-$as_echo to `as_echo', for better error message.
3564 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3566 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3567 `BASH_SOURCE' contain a newline, set them to empty, as they may
3568 not be unset.
3570 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3572 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3573 years and is too hard to maintain now. The last straw was
3574 reported by Jerker Baeck in
3575 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3576 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3577 * doc/autoconf.texi (Particular Functions): Move
3578 AC_FUNC_SETVBUF_REVERSED from here...
3579 (Obsolete Macros): ... to here. Say that it does nothing now.
3580 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3581 Turn into (almost) a no-op.
3583 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3584 (AC_C_VOLATILE):
3585 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3586 These macros are obsolescent and new applications shouldn't need them.
3587 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3588 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
3589 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
3590 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3591 (AC_FUNC_VPRINTF): Likewise.
3592 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3593 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3594 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3596 * doc/autoconf.texi (Setting Output Variables): Mention that
3597 @VAR1@VAR2 has unspecified behavior. Problem reported by
3598 Ralf Wildenhues.
3599 * NEWS: Mention this.
3601 * Makefile.am: Put only a single '#' into the copyright notice,
3602 so that it's also present in the output file. Standardize wording
3603 in makefile copyright notices to match GNU coding standards.
3604 * bin/Makefile.am: Likewise.
3605 * doc/Makefile.am: Likewise.
3606 * lib/Makefile.am: Likewise.
3607 * lib/freeze.mk: Likewise.
3608 * lib/autoconf/Makefile.am: Likewise.
3609 * lib/autoscan/Makefile.am: Likewise.
3610 * lib/autotest/Makefile.am: Likewise.
3611 * lib/m4sugar/Makefile.am: Likewise.
3612 * man/Makefile.am: Likewise.
3613 * tests/Makefile.am: Likewise.
3614 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
3615 one-line file.
3617 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3619 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3620 in the sed script that mangles the awk script: delete up to the
3621 first exclamation mark only.
3622 * tests/torture.at (Substitute and define special characters):
3623 Test '!' too.
3625 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3627 Rewrite config files generation: avoid quadratic growth in
3628 the number of substituted variables by using awk instead of sed
3629 for the bulk of the substitutions.
3630 * NEWS: Mention this.
3631 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3632 forbidden in the output (and thus input) file.
3633 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3634 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3635 generate just one large awk script for substitutions,
3636 eliminating much of the earlier complexity, while adding some
3637 new complexity. Only expand the substitution templates at
3638 configure time, for smaller configure script size. If
3639 _AC_SUBST_FILES are used, test 'awk' for working getline support
3640 at config.status time. If absent, interpolate through the
3641 shell. The awk script was written with much help
3642 from Paolo Bonzini and Paul Eggert.
3643 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3644 (_AC_SED_FRAG_NUM): Likewise.
3645 (_AC_SUBST_CMDS): Renamed from...
3646 (_AC_SED_CMDS): ...this.
3647 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3648 * tests/torture.at (Substitute a 2000-byte string): Also
3649 substitute a line with 1000 words, and a variable with several
3650 long lines.
3651 (Substitute and define special characters): Test awk special
3652 characters, and put substitution input strings `@foo@' in the
3653 output, to test that no recursion happens; test several other
3654 combinations from Paolo Bonzini.
3656 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3658 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3659 that replaced echo with AS_ECHO where this wasn't necessary.
3660 Problem reportd by Ralf Wildenhues.
3661 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3662 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3663 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3665 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3667 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3669 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3671 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3672 that traditional Awk lacks 3-arg "split". It has it.
3673 Mention that FS must be a single character, and a few other
3674 99-byte limits of traditional Awk.
3675 Mention that if (i in a) doesn't work with traditional Awk.
3677 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3679 * tests/autotest.at (BSx641-newline in command):
3680 (BS-BS-newline in command, BSx640-newline in command):
3681 (Newline-CODE-BS-newline in command):
3682 (Single-quote-BS-newline in command):
3683 (Single-quote-newline-BS-newline in command):
3684 Use printf '%s\n' instead of echo, for portability to hosts
3685 where echo interprets backslashes. This will break on hosts
3686 that lack printf, but for now let's assume all such hosts
3687 are dead (if not, we should get reports of test failures).
3689 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3691 'echo' has some portability problems, when given a first argument
3692 with a leading '-', or when given any argument containing '\'.
3693 Avoid using 'echo' in these cases.
3694 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
3695 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
3696 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3697 * lib/autotest/general.m4 (AT_INIT): Likewise.
3698 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
3699 argument might be unportable.
3700 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
3701 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.

3703 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
3704 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
3705 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
3706 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):

3717 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
3718 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3719 * bin/autoconf.as: Redo verbose flag implementation, as the old
3720 scheme wouldn't work with AS_ECHO.
3721 * lib/autotest/general.m4 (AT_INIT): Likewise.
3722 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3723 Don't use ECHO_T, since ECHO_N is now reliable.
3724 * lib/autotest/general.m4 (AT_INIT): Likewise.
3725 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3726 rather than using a here-document to put the script into a file.
3727 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
3728 use AS_ECHO.
3729 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3730 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3731 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3732 bug, but we might as well stop using ECHO_N and ECHO_C internally.
3733 * lib/autotest/general.m4 (AT_SETUP): Likewise.
3734 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
3735 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3736 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
3737 operand, as AS_ECHO requires. Avoid double file name expansion.
3738 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3739 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3740 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3741 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3742 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3743 Double-quote strings that would otherwise contain M4 comments.
3744 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3746 * configure.ac (AC_INIT): Bump to 2.61a.
3747 * NEWS: Likewise.
3749 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3751 Version 2.61.
3753 * configure.ac (AC_INIT): Bump to 2.61.
3754 * NEWS: Likewise.
3756 * tests/autotest.at (Macro with backslash in a test title):
3757 Comment out for now, as this tests neither fails nor passes
3758 reliably. Problem reported by Ralf Wildenhues.
3760 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3762 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
3763 in previous change, which caused test failures.
3765 2006-11-16 Stepan Kasal <kasal@ucw.cz>
3767 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
3768 code for --enable, --disable, --with, and --without to...
3769 (_AC_INIT_PARSE_ENABLE): ... a new macro.
3770 * doc/autoconf.texi (Package Options):
3771 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
3773 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3775 Import these changes from config via gnulib:
3777 2006-11-15 Ben Elliston <bje@gnu.org>
3779 From Josselin Mouette <joss@debian.org>:

3804 * standards.texi: core -> memory, throughout.
3805 (CPU Portability): show correct example of calling write
3806 on a char value; thanks to Paul Eggert for the code.
3807 Both of these suggestions from Eugene Y. Vasserman.
3810 Import these changes from texinfo via gnulib:

3850 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set

3852 Imported from a similar patch to gnulib by Bruno Haible.
3854 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3856 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

3880 argument. Extend to check titles printed by ./micro-suite and
3881 ./micro-suite -l and the title in micro-suite.log.
3882 (Backquote in a test title,
3883 Single-quote in a test title,
3884 Double-quote in a test title): Don't expect failure anymore.
3885 (Backslash in a test title): Put a non-whitespace character after the
3886 backslash so that Bourne shells might actually see it as an escape
3887 sequence.
3888 (Brackets in a test title,
3889 Pound in a test title,
3890 Comma in a test title,
3891 Quoted Macro in a test title,

3897 * tests/torture.at (#define header templates): M4-quote this title in
3898 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
3899 The visible effect was a stray [] in the testsuite output.
3901 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3903 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
3904 `trap ... 0' inside a function, for AIX sh.
3906 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3908 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3909 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3910 5363) simply issues a warning when dividing by zero at compile
3911 time. Problem reported by Elias Pipping.
3913 2006-10-26 Eric Blake <ebb9@byu.net>
3915 * THANKS: Update.
3916 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3917 show effect on macros that expand with commas.
3918 Reported by Joel E. Denny.
3920 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):

3942 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
3944 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3945 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3946 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3947 reported by Nelson H. F. Beebe for Coreutils 6.4.
3949 * tests/tools.at (autoconf --trace: user macros): Remove test
3950 for tracing multiline macros, since m4 1.4.7a uses a different
3951 way to number lines. Problem reported by Ralf Wildenhues.
3953 2006-10-24 Stepan Kasal <kasal@ucw.cz>
3955 * bin/autom4te.in (handle_m4): Do not redirect stdin to
3956 /dev/null since the heuristics for interactive behaviour was
3957 fixed in CVS m4.
3959 * bin/autom4te.in: With --force, always refresh the output
3960 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

3981 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
3982 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
3984 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3986 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
3988 2006-10-19 Eric Blake <ebb9@byu.net>

4010 2006-10-14 Stepan Kasal <kasal@ucw.cz>
4012 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
4013 looking for special shell characters.
4014 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4015 macro defined by AS_VAR_PUSHDEF before passing it as a
4016 parameter.
4017 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
4018 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

4027 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4029 (Imported from Automake.)
4030 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4031 which incorrectly sets the mode of an existing destination
4032 directory. In some cases the unpatched install-sh could do the
4033 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4034 system. We hope this is rare in practice, but it's clearly worth
4035 fixing. Problem reported by Alex Unleashed in
4036 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4037 Also, don't bother to check for -m bugs unless we're using -m;
4038 suggested by Stepan Kasal.
4040 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4042 Import this change from Automake:

4046 is enabled by default with gnu and gnits strictness.
4047 Report from Bruno Haible.
4049 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
4050 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
4051 gnu and gnits modes.
4053 Import this change from Config:
4055 2006-09-20 Ben Elliston <bje@gnu.org>

4058 Import this change from Gnulib:
4060 2006-09-16 Karl Berry <karl@gnu.org>
4061 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4062 to avoid sectioning errors.

4071 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
4072 (\code): must use new \...Char values, since now ` is active.
4074 2006-08-26 Karl Berry <karl@gnu.org>
4075 * build-aux/texinfo.tex (\textdegree): New command.
4077 2006-08-12 Karl Berry <karl@gnu.org>
4078 * build-aux/texinfo.tex (error \box0): smaller font.

4082 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
4084 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4086 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4087 added to the template can get mangled.
4089 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4091 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4092 include the default headers, and redefine obstack_chunk_alloc
4093 and obstack_chunk_free. Fixes false failure with glibc.
4095 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4097 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
4098 for backward compatibility with Libtool 1.5.22. Problem reported
4099 by Ralf Wildenhues.
4101 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4103 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
4104 AC_PROG_CC.

4107 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>

4112 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4114 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4115 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4116 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4117 Use a better substitute, by inspecting the output of "ls"
4118 rather than just using ":".
4119 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4120 rather than AS_EXECUTABLE_P, since we needn't worry about
4121 non-regular files here.
4123 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4124 due to configuration hassles with this. See Tonya Underwood's report
4125 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
4126 * doc/autoconf.texi (Special Shell Variables): Likewise.
4128 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4129 Stepan Kasal <kasal@ucw.cz>

4136 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4137 initialization which is not inherited through the environment
4138 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4139 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4141 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4143 * doc/autoconf.texi (Limitations of Usual Tools): Describe
4144 problems with mkdir -p -m.
4146 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4148 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4149 comment about ac_cpp_err; it was incorrect, and anyway
4150 ac_cpp_err is being removed below.
4151 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4152 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4153 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4154 nobody uses it.
4155 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4156 with werror_flag and conftest.err and so forth. This is more
4157 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4158 and anyway the user shouldn't normally want to see this gorp logged.
4159 Problem reported by Ralf Wildenhues.
4160 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4161 empty, not 'no', since the rest of the code uses 'test -z'.
4163 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4165 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4166 Use a single call to AC_DO_TOKENS rather than multiple, for
4167 efficiency.
4168 (_AC_LINK_IFELSE): Test that resulting file is executable.
4169 Problem reported by mwoehlke in
4170 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4172 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4173 than creating a file to use with test -x; this is much faster.
4175 2006-10-02 Bruno Haible <bruno@clisp.org>
4177 * lib/autom4te.in (Automake-preselections): Add
4178 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4180 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4182 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4183 standard error, `experr' should be used, not `expout'.
4185 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4187 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4188 fseeko testing program twice; just use the earlier result.
4189 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4190 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4191 still doesn't let the program compile.
4192 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4193 failed.
4195 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4196 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4197 include it, without including anything else.
4198 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4199 expressions.
4200 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
4202 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4204 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4205 `error.h', and include it, for a `error_at_line' prototype.
4206 Use a nonempty format string in the link test.
4207 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4208 for a declaration of wait3.

4213 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
4214 can apply to constants too, and that it checks for macro defns.
4215 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
4216 and simply cast the identifier to void. This handles structure
4217 values. Problem reported by Ralf Wildenhues.
4218 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
4220 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4307 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check

4317 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
4318 works with GNU M4 1.4.3 again; make the normalized form
4319 match the current m4 message; fix the description.

4328 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
4329 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
4330 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
4331 assume C89.

4353 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
4354 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
4355 accept files with extension `.f'. For consistency, also prefer
4356 xlf over f77.
4357 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug

4429 deal with LEXLIB.
4430 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
4431 didn't work if some values were cached but not others. Test for
4432 broken lex libraries like native ia64-hp-hpux11.22; see
4433 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
4434 work around the problem by preferring an empty LEXLIB to -lfl or
4435 -ll. Let the user set LEXLIB='' to indicate no library needed.
4437 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
4438 * README: Likewise.
4439 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

4636 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.

4667 reported by Keith Marshall. Also, don't bother with builddir2,
4668 since it shouldn't be needed any more.
4670 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

4692 Require that long long int be at least 64 bits wide. C99 requires
4693 this and enough programs depend on it so we should check for it.
4694 Bruno Haible reports in
4695 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4696 that long long int is 32 bits wide with some nonstandard compilers.
4697 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
4699 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
4701 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4702 to a nonexistent file, so that we don't have to worry about
4703 a local site configuration that doesn't use /usr/local.
4704 Problem reported by Keith Marshall in
4705 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4707 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4709 * doc/autoconf.texi: Be more consistent about using @acronym with
4710 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4711 quite right (it talked about "OSF/Tru64", even though the
4712 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4713 and it even mentioned "OSF 4"!) and at this point there's little
4714 reason to talk about OSF any more, since it died in 1994.
4715 (Specific Compiler Characteristics): Simplify example of
4716 negative-size array.
4717 (File Descriptors): Reorder to make the text flow better.
4718 Remove joke about "appreciate the various levels"; I didn't get it.
4719 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4720 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4721 (File Descriptors, Limitations of Usual Tools):
4722 Tone down the advice against renaming or removing open files.
4723 (Limitations of Usual Tools): Add a new section, on 'rm'.
4725 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4727 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4728 -lXt in LIBS, idea from Karsten Hopp; this was due since
4729 this change:
4731 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4732 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4733 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4734 (which belong to Xt, not X itself). See Debian bug 327655.
4736 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4738 * configure.ac (AC_INIT): Bump to 2.60a.
4739 * NEWS: Update.
4741 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4743 Version 2.60.
4745 * configure.ac, NEWS: Update.
4747 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4749 * config/texinfo.tex: Sync from upstream.
4751 * bin/autom4te.in (handle_traces): Transform the `@S|@'
4752 quadrigraph correctly in traces.
4754 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
4755 Fix typos.
4757 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
4758 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4759 not defined.
4760 * doc/autoconf.texi (Changed Directory Variables): New node,
4761 to document the whole `datarootdir' business a bit better.
4762 * NEWS: Update.
4763 * tests/torture.at (datarootdir workaround): Extend test.
4764 Prompted by report by Alexandre Julliard.
4766 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4768 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4769 when using default mode of IBM C 6 for AIX. Problem and two-line
4770 fix reported by Larry Jones.
4772 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4774 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4775 about literal '${datarootdir}' if a definition is found in the
4776 output file.
4778 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4780 * NEWS: Use "M4" rather than "m4" when appropriate.
4781 Problem reported by Eric Blake.
4782 * doc/autoconf.texi: Likewise.
4783 Use @acronym around BSD, GCC, and GNU when appropriate.
4784 (Why GNU M4): Renamed from "Why GNU m4".
4785 (Redefined M4 Macros): Mention that Posix
4786 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4787 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4788 to int.
4790 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4792 * bin/autom4te.in (handle_output): Do not forbid the empty
4793 pattern.
4794 * tests/tools.at (autoconf: the empty token): New test.
4796 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4798 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4799 calls, so that we do not care whether they are LIFO or FIFO;
4800 in the m4_wrap, do not check which diversion is the topmost
4801 one, just check that the stack is balanced at the end.
4802 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4803 base diversion forever--pop the previous diversion before
4804 opening the new one; consequently, remove the m4_wrap call.
4805 * lib/autotest/general.m4 (AT_INIT): Likewise.
4806 * tests/m4sugar.at: Do not use
4807 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
4809 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
4810 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4812 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4813 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4814 Rework example of m4wrap token-pasting trouble so that it doesn't
4815 care whether it's LIFO or FIFO.
4816 Fix some "contrary to"s that are awkward in English.
4818 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4820 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4821 to `yes' instead of `int$1_t' if the type is found, for more
4822 consistent configure output (where $1 is the number of bits).
4823 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4824 Suggested by Bruno Haible.
4826 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4827 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4828 with system headers. Report by Bruno Haible.
4830 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4832 * config/config.guess, config/config.sub: Sync from upstream.
4834 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4835 in order to avoid picking up an older installed frozen m4sh.m4f.
4836 Besides an outdated shell startup, this could have been created
4837 by an earlier M4 version with incompatible frozen file format.
4839 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4841 * README: Recommend m4 1.4.4 instead of 1.4.3..
4842 * doc/autoconf.texi: Likewise.
4843 (Special Chars in Names): Say that $(.FOO) is portable, as
4844 suggested by Stepan Kasal.
4845 (Installation Directory Variables, Build Directories):
4846 (Automatic Remaking, Subdirectories, Fortran Compiler):
4847 (Making testsuite Scripts, Defining Directories):
4848 Quote variable usages better.
4849 (Making testsuite Scripts): Add clean-local rule to makefile
4850 snippet, by Eric Blake.
4851 (Installation Directory Variables): Fix table item font.
4852 Reword slightly to clarify. Generalize advice about
4853 not using special characters to include all file-related
4854 vars, not just VPATH.
4855 (Special Chars in Variables): Warn about special characters in
4856 $(srcdir) too.
4857 (Assignments): Clarify default-value example as suggested by
4858 Ralf Wildenhues in
4859 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4860 (Special Shell Variables): Note leading ./ or ../, as suggested
4861 by Eric Blake.
4862 (Limitations of Builtins): Under cd, warn about CDPATH.
4863 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4864 Ralf Wildenhues.
4866 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4868 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4869 `@var', for texi2html.
4870 (Systemology): Some more word wrapping, for DVI output.
4871 (autom4te Invocation): The short option for `--melt' is `-M',
4872 not `-m'.
4874 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4876 * doc/autoconf.texi: More formatting and English tweaks,
4877 many suggested by Ralf Wildenhues.
4878 Reword to avoid "@code{...}'s" and the like, since it's ugly
4879 with Emacs info mode. discontents -> woes.
4880 Put a few "will"s back. time stamp -> timestamp.
4881 side-effect -> side effect.
4883 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4885 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4886 Warn about $@ not persisting. Problem reported by Julien Danjou in
4887 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4888 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4889 Mention other special chars, too.
4891 2006-06-14 Eric Blake <ebb9@byu.net>
4893 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4895 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4897 * doc/autoconf.texi: Some systematic minor improvements, as
4898 follows. Use "makefile" when talking about makefiles
4899 generally (which might be named "makefile" or "Makefile" or even
4900 "foo.mk"), "Makefile" when talking about a specific makefile
4901 called "Makefile". This unclutters the text from weird quotes
4902 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4903 values" rather than "@var{foo}s" and similar constructs containing
4904 "}s". Use "Make rules" rather than "Makefile rules". Minor
4905 English-language improvements. Change the prefix "sub-" to "sub"
4906 and "re-" to "re".
4907 Put blank lines around examples more consistently.
4908 Avoid "rather" and "very" as intensifiers.
4909 Avoid "will" as an auxiliary.
4910 (Limitations of Make): Split this node into....
4911 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4912 (Leading _ in Macro Names, Backslash-Newline-Newline):
4913 (Backslash-Newline Comments, Long Lines in Makefiles):
4914 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4915 (obj/ and Make, make -k Status, VPATH and Make):
4916 (VPATH and Double-colon, $< in Explicit Rules):
4917 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4918 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4919 New nodes, resulting from splitup of Limitations of Make.
4920 All cross-references changed. Raise the top node from
4921 a section to a chapter, and all subnodes accordingly.
4922 Redo the introductory wording to match the new organization.
4923 (Installation Directory Variables): Use an example that is
4924 closer to what Autoconf actually does. Mention that VPATH's
4925 value should not contain metacharacters or white space.
4926 (Fortran Compiler): Fix a VPATH bug in an example.
4927 (Leading _ in Macro Names): Mention that this problem is no longer
4928 of practical concern.
4929 (VPATH and Make): Reword the advice to make it clearer
4930 that Autoconf and Automake support VPATH in non-GNU make, but
4931 many packages have bugs in this area.
4932 ($< in Explicit Rules): Refer to Build Directories rather
4933 than using a (non-VPATH-safe) example.
4934 (Automatic Rule Rewriting): Mention the sort of disaster that
4935 can ensue with Solaris-style rule rewriting with VPATH.
4937 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4939 * doc/install.texi (Compilers and Options): Weaken the
4940 suggestion to use GNU make for VPATH builds.
4942 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4943 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4945 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4946 in regular expression.
4948 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4950 * doc/autoconf.texi (Installation Directory Variables):
4951 Drop extra @samp from `@table @samp' item.
4952 (Limitations of Usual Tools): Comment fix.
4953 Do not nest @samp just to point to other table items.
4954 (Writing testsuite.at) <AT_CHECK>: The second argument to
4955 `@dvar' is already @samp'ed.
4956 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4957 do not use @var in the second argument.
4959 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4961 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4962 $as_shell.exe too. Problem reported by Andreas Buening in
4963 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
4965 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4967 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4968 `unused variable' compiler warning, for `-Wall -Werror'.
4969 Reported by Jaap Haitsma in
4970 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4972 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
4974 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4975 case the compiler dumps core. Problem reported for
4976 OpenServer 5.0.7 by Tim Rice in
4977 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
4978 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4979 Likewise.
4981 2006-06-06 Tim Rice <tim@multitalents.net>.
4983 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
4984 "ERROR" only shows up in "make check" output if there is an
4985 error.
4987 2006-06-06 Eric Blake <ebb9@byu.net>
4989 * tests/tools.at (automatically allowed tokens): Fix typo.
4991 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4993 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
4995 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
4996 typically overflows on x86 CPUs, even though the C standard
4997 requires otherwise.
4999 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5001 * configure.ac (AC_INIT): Bump to 2.59e.
5002 * NEWS: Update.
5004 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5006 Version 2.59d.
5008 * config/texinfo.tex: Sync from upstream.
5010 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5011 seen, invoke libtoolize with `--ltdl' argument.
5012 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5013 * NEWS: Update.
5014 Suggested by Eric Blake.
5016 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5018 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5019 reported by Ralf Wildenhues.
5020 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
5022 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5024 * THANKS: Update.
5026 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5028 * doc/autoconf.texi: Modernize some of the references to Solaris.
5030 2006-06-05 Stepan Kasal <kasal@ucw.cz>
5032 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5033 message issued by AC_REQUIRE.
5034 * tests/m4sugar.at: Check m4_require's error message.
5035 * tests/base.at: Check AC_REQUIRE's error message.
5036 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5037 to...
5038 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5039 AT_CHECK_M4.
5040 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5041 `expout' as the last parameter.
5042 * tests/tools.at: Adapt to the above change.
5044 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5046 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5047 information about race-free implementations of mkdir.
5049 2006-06-04 Eric Blake <ebb9@byu.net>
5051 * bin/autoreconf.in (help): Document M4 environment variable.
5052 * bin/autoconf.as (Usage): Likewise.
5053 * bin/autom4te.in (help): Likewise.
5054 * doc/autoconf.texi (autom4te Invocation): Likewise.
5056 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5058 * NEWS: GNU make now recommended for VPATH builds.
5059 Mention that some macros are now documented to be obsolescent.
5060 * doc/autoconf.texi:
5061 Prefer "current" to "modern" to describe
5062 currently-used (albeit perhaps old-fashioned) hosts.
5063 Mention which ancient features no longer need to be worried about.
5064 setgid -> set-group-ID
5065 setuid -> set-user-ID (these are the Posix terms)
5066 Fix some misuses of "only".
5067 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5068 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5069 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
5070 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
5071 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
5072 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
5073 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
5074 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
5075 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
5076 Mention that these macros are obsolescent.
5077 (Installation Directory Variables): shall -> should
5078 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5079 Mention that it's now safe to use 3 and 4.
5080 (Limitations of Usual Tools): cp -r is now specified by Posix.
5081 Omit longwinded and obsolescent discussion of cp -f.
5082 Modernize discussion of expr, ls.
5083 (Limitations of Make): Modernize discussion of VPATH builds.
5084 Mention $? as a workaround in some cases.
5085 * doc/install.texi (Basic Installation):
5086 Mention "./configure; make; make install" first. Be more
5087 specific about why this file is generic. Remove unnecessary
5088 parens. Remove misleading "only". Remove obsolete advice
5089 about csh. Don't say "configure" takes awhile; say it
5090 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5091 and CC=c99 rather than CC=c89, as these are blessed by current
5092 Posix. Recommend GNU make if doing a VPATH build.
5094 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5096 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5097 examples involving shell prompts.
5099 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5100 and Paul Eggert <eggert@cs.ucla.edu>
5102 * doc/autoconf.texi (Here-Documents): Add details about the
5103 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5104 use "here-documents" instead of "here documents".
5106 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5108 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5110 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5112 * doc/autoconf.texi (File System Conventions): Warn about ":"
5113 anywhere in directory names.
5115 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5117 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5118 about quoting the case statement, just in case.
5119 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5120 was fixed in ksh93g; reported by Ralf Wildenhues.
5122 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5124 * doc/autoconf.texi (System Services): Do not document
5125 overriding EXEEXT via ac_cv_exeext=ext.
5126 (Particular Programs) <AC_PROG_MKDIR_P>:
5127 Document that ${MKDIR_P} understands --.
5128 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5129 comment.
5131 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5133 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5134 argument with leading hyphen. Problem reported by Paul Eggert.
5136 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5138 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5139 about quoting ac_try: quote all of it, if any of it seems suspicious.
5140 This means we don't have to worry about ${ or sed any more.
5141 Also, double-quote the case statement, to work around misuses via
5142 underquoting as reported by Ralf Wildenhues in
5143 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5144 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5145 undocumented and dangerous macro.
5146 Problem reported by Ralf Wildenhues in
5147 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5149 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5151 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5152 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5153 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5155 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5157 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5158 since evidently some packages rely on the old, broken behavior.
5159 Problem reported by Ralf Wildenhues in
5160 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5161 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5162 pre-2006-05-26 definitions, but leave in the comments that
5163 these macros are dangerous and should not be used.
5164 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5165 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5166 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5167 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5168 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5170 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5172 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5173 the use of 'tr', since this is our only use of 'tr'.
5175 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5176 and Paul Eggert <eggert@cs.ucla.edu>
5178 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5179 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5181 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5183 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5184 the output file in the `${datarootdir}' test.
5186 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5187 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5189 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5190 mention of `datarootdir' in the input file(s), but literal
5191 `${datarootdir}' in the output file, and we haven't warned yet,
5192 then warn as well: the user may have (erroneously) used
5193 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5194 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5195 * tests/torture.at (datarootdir workaround): Extend this test.
5196 * NEWS: Update.
5198 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5199 and Paul Eggert <eggert@cs.ucla.edu>
5201 * doc/autoconf.texi (autoheader Invocation): The first argument to
5202 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5203 alternatives and clear up the language a bit.
5205 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5207 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5208 ac_config_guess, ac_config_sub, ac_configure.
5209 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5210 Fix typo that prevented an unnecessary space from being removed.
5211 Problems reported by Ralf Wildenhues in:
5212 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5214 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5216 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5217 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5218 Don't use the term "thread-safe" to talk about mkdir race
5219 conditions, since the problem is more a process than a thread
5220 issue. Problem reported by Stepan Kasal in:
5221 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5222 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5223 the test for 'install' more closely. Look at MKDIR_P first.
5224 Look in the PATH, and at /opt/sfw/bin.
5225 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5226 Don't bother to try mkdir -p, since we already check mkdir --version;
5227 just look at the version number. (There's no easy way to check
5228 for race-free implementations.)
5229 * tests/tools.at (autoconf: subdirectories): Adjust to above
5230 changes, since MKDIR_P now might end in "/mkdir -p".
5232 * doc/autoconf.texi (autoheader Invocation): Mention that the
5233 first arg of AC_DEFINE_UNQUOTED must be a literal.
5234 Problem reported by Ben Pfaff in
5235 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5237 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5238 * doc/autoconf.texi (Special Chars in Variables): New section.
5239 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5240 (Installation Directory Variables): Quote $(datadir) better.
5241 (Limitations of Builtins): Describe some of eval's trickiness.
5243 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5244 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5245 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5246 in front of every arg, not just trailing args. Quote apostrophes.
5247 (_AC_EVAL_ECHO): New macro.
5248 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5249 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5250 removed.
5251 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5252 exposed by quoting of eval argument. Put the command on line line
5253 so it logs better.
5254 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5255 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5256 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5257 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5258 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5259 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5260 Use eval more safely.
5261 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5262 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5263 to be replaced.
5264 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5265 lines, exposed by quoting of eval argument.
5267 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5268 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5270 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5271 initialization of `ac_cv_exeext', do not override it if it was
5272 already set, unless it was set to `no', for compatibility with
5273 Autoconf-2.13, and comment this.
5274 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5275 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5276 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5277 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5278 Document that this test may be overridden by setting
5279 `ac_cv_exeext'.
5281 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5283 Revert these two patches:
5285 2006-04-06 Eric Blake <ebb9@byu.net>
5286 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5287 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5288 2006-04-01.
5290 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5291 Clean up _AC_COMPILER_EXEEXT* macros.
5292 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5293 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5294 ac_file to the name of the default output file and call
5295 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5296 initial `rm' of the candidate files...
5297 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5298 the same list in subsequent `rm' calls, and for the temporary
5299 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5300 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5301 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5302 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5303 no longer needed) by libtool. Make it a cache check.
5304 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5305 copied here by mistake.
5306 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5307 _AC_COMPILER_EXEEXT.
5308 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5309 _AC_COMPILER_OBJEXT directly.
5310 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5312 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5314 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5315 Fix description of how the buggy `sed' works.
5317 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5319 Sync from Automake:
5321 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5322 ENOLCK. Only mention `make -j' when applicable. Only raise
5323 fatal errors when `make -j' is involved. Improve error message.
5325 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5327 * doc/autoconf.texi (Here-Documents): We now know more about
5328 the variable expansion in here documents bug.
5329 Thanks to Tim Rice and Stepan Kasal.
5331 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5332 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5334 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5336 * tests/autotest.at (Multiline command from M4 expansion):
5337 No failure to be expected if the shell quotes newlines in
5338 commands in the `set -x' output. Report by Tim Rice.
5339 * THANKS: Update.
5341 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5343 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5344 expansion in the here-documents used by config.status, as that
5345 runs afoul of the Korn shell version M-12/28/93d bug described in
5346 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5347 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5348 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5350 2006-05-23 Jim Meyering <jim@meyering.net>
5352 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5353 Fix typo introduced with 2006-04-02 change. It reversed the sense
5354 of the test.
5356 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5358 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5359 ac_dB slightly, to save bytes in the script.
5360 Max out at 50 lines, rather than 96; this is more likely
5361 (though not guaranteed) to avoid obscure 'sed' failures.
5363 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5365 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5366 `tr -d -' as bad option argument. Work around this by deleting
5367 an unrelated character.
5368 Report by Tim Rice <tim@multitalents.net>.
5370 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5371 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5372 Stepan Kasal <kasal@ucw.cz>
5374 * doc/autoconf.texi (Particular Programs): Do not promise that
5375 we always prefer the GNU version of the program, and that we
5376 search according to PATH; both rules can have exceptions.
5377 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5378 AC_PROG_SED. Move descriptions of limitations
5379 to the Limitations of Usual Tools section.
5380 (Limitations of Usual Tools) <sed>: Mention script length
5381 limitations with Solaris /usr/ucb/sed.
5382 <grep>: Fix wording for empty alternative. Mention that -c and
5383 -l should not be combined, and that -E and -F should not be
5384 combined.
5386 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5387 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5389 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5390 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5392 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5394 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5395 AC_DEFINE is now passed to m4_pattern_allow.
5396 * NEWS: Mention that; likewise for AC_SUBST.
5397 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5398 the parameter to m4_pattern_allow.
5399 * tests/tools.at: Add a check for that.
5401 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5403 * lib/autoconf/status.m4: Fix typos.
5405 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5407 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5408 only the files that this macro generates.
5410 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5412 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5413 the HP-UX sed limitation of 99 commands, labels do not count.
5414 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5415 in the comment.
5416 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5418 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5420 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5421 Import the following fix from coreutils:
5423 2006-01-13 Jim Meyering <jim@meyering.net>
5425 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5426 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5427 not double-quote uses of that variable, to accommodate the rare
5428 case in which getmntent is available in none of the libraries
5429 checked. This happens at least on FreeBSD 5.0.
5431 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5433 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5434 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5435 some other programs unwisely rely on these undocumented vars.
5436 But put in warning comments about them.
5437 Problem reported by Ralf Wildenhues in
5438 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5439 * NEWS: Document that these variables are intended to go away.
5441 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5443 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5444 and set the language to C++ (analogous to the equivalent Fortran
5445 tests).
5447 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5448 * doc/autoconf.texi (C++ Compiler): Document it.
5449 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5450 * NEWS: Update.
5452 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5454 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5455 that caused config.status to generate 100-command sed scripts; the
5456 portable limit is 99.
5458 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5460 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5461 variable `ac_d' instead of `d' to avoid infringing namespace.
5462 Report by Ralf Menzel.
5464 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5466 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5467 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5468 * tests/tools.at (autoconf: subdirectories): New test, taken from
5469 the corresponding problem report by Ralf Wildenhues in:
5470 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5472 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5473 Quote some uses of shell variables if they might suffer unexpected
5474 globbing. This doesn't fix all instances of quoting problems that
5475 I found, just the easy ones that look safe.
5476 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5477 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5478 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5479 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5480 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5481 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5482 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5483 Likewise.
5484 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5485 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5487 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5489 * bin/autoreconf.in ($help): Reword according to the manual.
5490 Suggested by Olly Betts.
5492 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5493 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5495 * bin/autoreconf.in: Pass the directory argument to
5496 `require_configure_ac'. Fix comment.
5497 * tests/torture.at (Configuring subdirectories): Expose this.
5498 Reported by Olly Betts.
5500 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5502 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5503 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5504 Automake as follows:
5506 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5507 `$configure_in' instead of `configure.in', to preserve
5508 directory component.
5510 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5512 * config/config.guess, config/config.sub, config/texinfo.tex,
5513 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5515 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5517 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5518 test for C99 conformance; (bool) 0.5 is an integer constant
5519 expression, but (bool) -0.5 is not. Problem reported by Fedor
5520 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5522 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5524 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5525 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5526 Warn about obsolete install-sh files. Remove stray sentence
5527 fragment and fix cross reference.
5528 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5529 install -d; this undoes the 2006-05-10 change.
5530 (MKDIR_P): Mark with AN_MAKEVAR.
5531 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5532 that we don't require $INSTALL to be thread-safe. Move comments
5533 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5534 of AC_PROG_INSTALL. Output a message saying that we're checking
5535 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5536 MKDIR_P instead of AC_SUBST.
5537 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5538 Special magic for MKDIR_P, too.
5539 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5540 a dnl.
5541 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5543 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5545 Sync from Automake, as follows:
5547 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5548 * config/install-sh: Initialize IFS, so field splitting isn't
5549 turned off later.
5550 * config/mkinstalldirs: Likewise.
5551 * config/missing: Remove superfluous quotes. Replace all uses of
5552 `[' by `test', for consistency, and for..
5553 * config/missing (sed_minuso, sed_output): New variables.
5554 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5555 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5556 Fixes `missing' to detect `--output' for help2man. Fixes
5557 PR automake/483. Report by Dennis J. Linse.
5558 (autom4te): Document in `missing --help'.
5560 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5562 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5563 * config/install-sh: Don't use 'path' to talk about file names,
5564 as per GNU coding standards. Close a race condition reported by Ralf
5565 Wildenhues and Stepan Kasal. There is still a race condition
5566 on hosts that predate Posix 1003.1-1992, but we can't help this.
5567 Don't mishandle weird characters like space on pre-Posix hosts.
5568 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5569 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5570 AC_PROG_MKDIR_P from AS_MKDIR_P.
5571 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5572 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5573 earlier editions are not (including Automake 1.8.3).
5574 Do not suggest mkinstalldirs for thread-safety.
5575 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5576 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5577 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5578 presence of special characters and race conditions.
5579 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5580 in Autoconf's name space.
5582 2006-05-10 Bruno Haible <bruno@clisp.org>
5583 and Paul Eggert <eggert@cs.ucla.edu>
5585 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5586 from Automake with minor changes.
5587 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5589 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5591 * config/install-sh: Update to Automake CVS version, as follows:
5592 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5593 * lib/install-sh: Simplify the expr implementation of dirname.
5594 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5595 * lib/install-sh: Handle --, and diagnose unknown options.
5597 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5599 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5600 `./autom4te' to create `./testsuite', since the `all' target
5601 will ensure its presence, but `installcheck' should not create
5602 the uninstalled wrappers.
5604 * tests/torture.at (Unusual Automake input files): Skip if we
5605 detect automake < 1.8.
5607 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5609 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5610 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5611 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5612 * NEWS: Update.
5614 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5616 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5617 munge (multiple) white space and other oddities.
5618 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5619 single quotes in variable assignment.
5620 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5621 and similar failures by adding multiple spaces, tabs, and other
5622 special characters.
5623 Report and different test suggested by Francesco Romani
5624 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5626 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5627 single quotes, we only need to search for single quotes; this
5628 both simplifies the search pattern, and makes us less
5629 susceptible to `echo' variations for arguments not containing
5630 single quotes.
5631 (_AC_ARG_VAR_VALIDATE): Likewise.
5633 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5635 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5636 `$*' and IFS concatenation issue with traditional shells and
5637 bash-2.04. Report by Seanster@Seanster.com.
5639 2006-05-03 Bruno Haible <bruno@clisp.org>
5641 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5642 precisely which Mac OS X versions have the od problem.
5644 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5646 * doc/autoconf.texi: Use @option systematically.
5648 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5649 and Bruno Haible <bruno@clisp.org>
5651 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5652 about 'od'.
5653 (Integer Overflow): Mention the special case of integer division
5654 overflow.
5656 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5658 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5659 traditional shells like the Solaris one that do not use the
5660 first IFS character for assembling `$*'.
5661 Prompted by a related report from autoconf_bug@nro.ca.
5663 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5664 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5666 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5667 Mention more problems with the -e option.
5669 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5671 * NEWS: Typo.
5672 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5674 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5675 in URLs to improve DVI formatted output (requires texinfo 4.6).
5676 (System Services, Systemology, Shellology): Likewise.
5677 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5678 output.
5680 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5681 continuous text.
5682 (Runtime): Fix macro argument names to match description:
5683 `action-if-found' -> `action-if-true' and similarly.
5684 (Obsolete Macros): Likewise.
5685 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5686 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5687 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5689 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5691 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5693 * ChangeLog: Typo.
5694 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
5695 DVI output.
5697 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5699 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
5700 /bin/sh set unsorted output.
5701 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
5702 * tests/local.at: Likewise.
5704 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
5706 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
5707 (Integer Overflow, Null Pointers, Buffer Overruns):
5708 (Floating Point Portability, Exiting Portably): New sections.
5709 (Writing Test Programs): Fix some langauge. Recommend exiting
5710 with status 1, not merely nonzero. Clarify exit declaration.
5711 (Run Time): Move C exit status stuff to new Exiting Portably section.
5712 (Systemology): Mention Posix and levenez. Update v7 reference.
5713 (Portable Shell): Mention the Posix shell.
5715 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5717 * bin/autoconf.as (me): Replace by as_me.
5719 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5721 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5722 since as_me isn't set yet.
5724 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5726 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5727 a few minor bugs in this area.
5729 * doc/autoconf.texi (Programming in M4sh): Comment out the
5730 documentation of AS_BASENAME, for now.
5731 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5732 (Limitations of Builtins) <basename>: Do not refer to
5733 AS_BASENAME.
5734 * bin/autoconf.as (me): Don't use AS_BASENAME.
5735 (dir): Remove the unused variable.
5736 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5737 AS_DETECT_REQUIRED. All uses changed.
5738 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
5739 All uses changed.
5740 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
5741 (AS_BASENAME): Use "basename --" to protect against leading "-".
5742 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
5743 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
5744 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
5745 (_AS_DIRNAME_PREPARE): Likewise.
5746 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
5747 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
5748 (AS_DIRNAME): Use "dirname --".
5750 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5752 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5753 of "run time" and "run-time" changed to "runtime", for consistency.
5754 * lib/autoconf/fortran.m4: Likewise (in comment).
5755 * lib/autoconf/functions.m4: Likewise.
5756 * lib/autoconf/general.m4: Likewise.
5757 * lib/autoconf/headers.m4: Likewise.
5759 * doc/autoconf.texi (Run Time): Document the exit status situation
5760 with more accuracy and detail.
5762 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5764 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5765 Archive is not officially `GNU' any more. Update URL.
5766 (Defining Directories): Likewise
5767 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5769 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5771 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5772 newline from the `trap' code to finish `config.log'; the NetBSD
5773 /bin/sh resets the exit status after an empty command, as
5774 documented in doc/autoconf.texi.
5775 Reported by Dalibor Topic <robilad@kaffe.org>.
5777 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5779 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5780 Suggested by Bruno Haible.
5782 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5784 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5785 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5786 Instead, just list the shells that we know work.
5787 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5788 changed. Be more cautious about the _cv_ variable.
5789 * tests/tools.at (Syntax of the shell scripts): Check the
5790 _cv_ variable once, at first, to avoid an internal autoconf error
5791 when sh -n does not work.
5793 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5795 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5797 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5799 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5800 use ">&-" since we're only 99.999% sure that this is portable,
5801 and since the MinGW bug is fixed in a different way.
5802 * lib/autotest/general.m4 (AT_INIT): Likewise.
5804 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5806 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5807 before opening config.log, to avoid hitting a bug on MinGW.
5809 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5811 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5812 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5813 This works around a MinGW bug reported by Eric Paire.
5814 Make sure that all writes to the log file append to it,
5815 rather than possibly losing data.
5816 * lib/autotest/general.m4 (AT_INIT): Likewise.
5818 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5820 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5821 description.
5823 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5825 * NEWS: Update.
5827 * configure.ac (AC_INIT): Bump to 2.59d.
5829 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5831 Version 2.59c.
5833 * Makefile.maint (news-date-check): Do not require a leading `*'
5834 before the release date in NEWS.
5836 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5837 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5839 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5840 the instantiated file do not contain the string 'datarootdir'
5841 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5842 @mandir@, replace the reference '${datarootdir}' by the value.
5843 * tests/torture.at (datarootdir workaround): New test.
5844 * NEWS: Advertise this temporary fixup.
5845 Based on a patch by Bruno Haible, reported and analyzed by
5846 Paul Eggert and Noah Misch.
5848 2006-04-12 Eric Blake <ebb9@byu.net>
5850 * tests/autotest.at (Debugging a failed test): Fix comment.
5852 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5854 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5855 all the changes since 2006-04-07.
5857 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5859 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5860 succeeded, but `ln -s file dir' failed, take care to remove the
5861 leftover target before the next test, to prevent its spurious
5862 failure; also make sure `ln file dir' works before selecting it.
5863 Thanks to Keith Marshall for pointing this out.
5864 * THANKS: Update.
5866 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5867 assignments in `at_debug_args', so that we put them correctly
5868 in the `run' script.
5869 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5870 Reported by Eric Blake.
5872 2006-04-11 Eric Blake <ebb9@byu.net>
5874 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5875 top-level tests after micro-suite has been run. Used in...
5876 (Debugging a successful test, Debugging script and environment),
5877 (Debugging a failed test): ...these new tests. The first of these
5878 is fixed by...
5879 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5880 macro, split out from...
5881 (AT_INIT): ...here, so that using -d also generates a run script.
5882 Document that -d inhibits top-level logging.
5883 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5884 inhibits top-level logging; debug scripts are created.
5886 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5887 check.
5888 * tests/autotest.at (Empty test, Empty check): New test to check it.
5890 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5891 from gcc.
5893 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5895 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5896 the files if a problem appears. Make the empty *.at files
5897 read-only, too. Proposed by Ralf Wildenhues.
5899 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5901 * config/Makefile.am: Add comment to force updated Makefile.in.
5903 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5904 space only patch to this file, this patch causes the Makefile.in
5905 files that include freeze.mk to be updated, and thus have a
5906 newer time stamp again, which in turn makes a pristine CVS
5907 checkout have correct time stamps.
5909 * Makefile.maint (cvs-sv): New macro, to be used..
5910 (config.guess-url_prefix, config.sub-url_prefix)
5911 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5912 point to CVS text checkout of Gnulib files.
5913 (copyright-check): Bump current year.
5914 (announcement): Do not hard-wire `./announce-gen'.
5915 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5916 correctly.
5917 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5918 `chmod +x'.
5919 (wget_files): Update config.guess, config.sub, texinfo.tex by
5920 `wget-update', now that their URLs work again.
5922 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5924 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5925 Problem noted by Paul D. Smith.
5927 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5929 * doc/autoconf.texi: Remove unused words from word list.
5930 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5931 .x-sc_trailing_space: New files.
5933 * doc/standards.texi: Sync from gnulib.
5935 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5936 `LIBOBJDIR' as experimental.
5938 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5939 with a target directory; it's internally implemented as `cp'
5940 anyway, but since Autoconf advertises the possibility to use
5941 a target directory when LN_S is `ln -s', we need to find out.
5942 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5943 analyzed by Keith Marshall <keith.marshall@total.com>.
5945 * THANKS: Update.
5947 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5949 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5950 confdefs.h as-is. In general, if it has backslash-newline or the
5951 like, then it doesn't work either to sort or to remove empty
5952 lines.
5954 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5956 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
5958 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
5960 * lib/autom4te.in (Automake-preselections): Preselect
5961 _AM_SUBST_NOTMAKE.
5963 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5965 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5966 apostrophe within a single-quoted string, as this is the usual
5967 tradition and is easier to read than '"'"'. Don't rely on the
5968 shell treating "$/" like '$/'. Use a more-consistent indenting
5969 style for the trap.
5971 2006-04-09 Eric Blake <ebb9@byu.net>
5973 * tests/autotest.at (Backquote command substitution),
5974 (Multiline backquote command substitution): Remove mistaken
5975 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
5976 applied...
5977 (Parenthetical command substitution, Multiline parenthetical
5978 command substitution): here.
5980 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5982 Import macros from gnulib (often changing their name).
5984 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
5985 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
5986 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
5987 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,
5988 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T,
5989 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
5990 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
5991 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
5992 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
5993 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
5994 The manual mentions Gnulib more prominently.
5995 * doc/autoconf.texi (Gnulib): New node.
5996 (Pointers): Add Gnulib URL.
5997 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
5998 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
5999 Gnulib section.
6000 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
6001 suggest a #define rather than a typedef for _Bool, and mention
6002 Gnulib rather than trying to substitute stdbool code.
6003 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
6004 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
6005 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
6006 AC_STRUCT_DIRENT_D_TYPE.
6007 (Particular Types): Mention stdint.h and inttypes.h as standard
6008 headers too.
6009 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
6010 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
6011 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
6012 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
6013 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6014 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6015 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention

6057 Revert the patch from 2006-04-01 and only improve
6058 _AS_DETECT_BETTER_SHELL:
6060 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6061 skip nonexistent directories.
6062 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6063 only shell candidates which exist.
6064 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6065 * lib/autotest/general.m4 (AT_INIT): No need to give three
6066 parameters to _AS_PATH_WALK.
6068 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
6069 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6071 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6072 distinguish m4sugar macros.
6073 * tests/tools.at (autoupdating with aclocal and m4_include):
6074 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6075 test case by Noah Misch <noah@cs.caltech.edu>.
6077 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6079 Revert my change from 2006-03-17, in other words:
6080 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
6081 and DUALCASE=1.
6082 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
6083 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
6084 it is set.
6086 2006-04-07 Eric Blake <ebb9@byu.net>
6088 * doc/autoconf.texi (Programming in M4sh): Document that
6089 AS_MKDIR_P exits the script on failure.
6090 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6092 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6094 * config/elisp-comp, config/install-sh, config/mdate-sh,
6095 config/missing, config/mkinstalldirs: Sync from Automake.
6097 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
6098 from Automake.
6100 * doc/make-stds.texi: Sync from gnulib.

6104 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6105 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced

6111 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6113 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6114 whether `set' quotes correctly: redirect stderr of the tested
6115 `set', and use a subshell, for Ultrix; use `sed' instead of
6116 `grep' for zsh `set' which may write binary output; match only
6117 at the beginning of a line, to avoid false positives.
6118 In order to avoid false positives by unrelated variables with
6119 multiline content, put the dump algorithm in a subshell and
6120 unset all variables containing newlines (except some which are
6121 special to the shell). Warn about cache variables that are
6122 unset.
6124 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6126 * config/config.guess, config/config.sub, config/texinfo.tex:

6135 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
6136 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
6137 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
6138 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
6140 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
6141 shell issue with double-quoted command substitutions of native
6142 commands.

6163 * tests/Makefile.am (maintainer-check-posix):
6164 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
6166 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
6167 ac_config_<foo>s again, sometimes normalized, sometimes not.
6168 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6169 (AC_CONFIG_COMMANDS): Do not do so here.
6170 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6171 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6172 2005-07-25 rewrite. Noticed by Noah Misch.
6174 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6175 _AC_PRESERVE_HELP_ORDER, ...
6176 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
6178 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
6179 inside m4_expand_once; it is redundant.
6181 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
6182 for --help from Cygnus `configure.'
6184 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

6194 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
6195 Noah Misch <noah@cs.caltech.edu>
6197 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
6198 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
6199 * doc/autoconf.texi (Help Formatting): New node.
6200 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
6202 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6204 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
6205 lib/autoconf/specific.m4, lib/autoconf/status.m4,
6206 lib/autoconf/types.m4, lib/autotest/general.m4,
6207 tests/mktests.sh, tests/torture.at: White space cleanup:
6208 remove some SPACE before TAB, or add quoting ('' or @&t@).
6210 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
6212 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
6214 2006-04-05 Eric Blake <ebb9@byu.net>
6216 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
6217 empty test suite works.
6218 * tests/autotest.at (Empty test suite): Remove xfail.
6220 2006-04-05 Noah Misch <noah@cs.caltech.edu>

6223 TAGS to ac_config_<foo>s.
6224 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
6225 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
6226 normalizing it, consistent it with previous releases.
6227 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
6229 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
6231 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
6232 Use simplified args that Eric Blake originally suggested.
6234 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
6236 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6237 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
6238 Use 'comm' rather than N instances of grep; this also fixes a bug
6239 whereby substrings were incorrectly matched, causing us to not
6240 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
6241 (exclude_list): Exclude empty macros.
6242 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
6244 Use awk rather than grep -E or egrep, to avoid
6245 portability problems with regular expressions containing newlines.

6247 Switch from grep to awk syntax.
6248 (ac_exclude_script): Renamed from ac_exclude_egrep.
6249 (au_exclude_script): Renamed from au_exclude_egrep.
6251 2006-04-04 Noah Misch <noah@cs.caltech.edu>
6253 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
6254 a subdirectory subject to Cygnus `configure'.
6255 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
6257 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
6258 report request when we have no AC_PACKAGE_BUGREPORT.
6260 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6262 * THANKS: Update.

6265 generated files.
6267 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
6268 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
6269 typedef'ed restricted pointer, to catch a compiler bug on
6270 HP-UX 11.x, and fix warnings so it passes with -Werror.
6271 (_AC_PROG_CC_C99): Likewise.
6272 Reported by Albert Chin <china@thewrittenword.com>.
6273 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.

6288 * THANKS: Add myself.
6290 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6292 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
6293 to log, point to testsuite output tree.
6295 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
6297 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
6298 * doc/autoconf.texi (Function Portability): Mention that C++

6302 Remove; all uses removed.
6303 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

6323 Clean up _AC_COMPILER_EXEEXT* macros.
6325 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6326 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6327 ac_file to the name of the default output file and call
6328 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6329 initial `rm' of the candidate files...
6330 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6331 the same list in subsequent `rm' calls, and for the temporary
6332 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6333 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6334 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6335 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6336 no longer needed) by libtool. Make it a cache check.
6337 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6338 copied here by mistake.
6339 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6340 _AC_COMPILER_EXEEXT.
6341 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
6342 _AC_COMPILER_OBJEXT directly.

6373 * lib/autoconf/general.m4 (_AC_INIT_VERSION): Emit script name and
6374 Autoconf version number despite a zero- or one-argument AC_INIT.
6376 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
6377 subordinate tools.
6378 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
6379 * doc/autoconf.texi (autoreconf Invocation): Document it.
6381 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
6382 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.

6388 rm failed to remove it.
6390 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6392 * bin/autoupdate.in: Redefine m4_location so that warnings print
6393 the correct lines of the input file by subtracting..
6394 (_au__first_line): ..this new definition.
6396 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
6397 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
6398 Remove stray newline in output.
6399 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
6400 AC_DEFUN this for autoconf, including the obsoletion diagnose.
6401 Fixes autoupdating of code where the replacement output contains
6402 m4sugar macros.
6403 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
6404 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

6406 * tests/tools.at: Several new tests for all of this.
6407 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
6408 hairy details.
6409 The AC_LANG_SAVE issue was reported against Libtool by
6410 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
6411 Kristian Kvilekval <kris@cs.ucsb.edu>.
6413 2006-04-01 Stepan Kasal <kasal@ucw.cz>
6415 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
6416 switch all of them on and of when necessary. Fixes the bug when
6417 m4sugar macros (e.g., m4_define) were expanded after the first
6418 automatic update (e.g., after AC_PREREQ or AC_INIT).
6420 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

6445 aclocal cannot be given on the command line.
6447 2006-03-29 Paul Eggert <eggert@cs.ucla.edu>
6449 * doc/autoconf.texi (Programming in M4sh): Mention AS_BASENAME.
6450 Give an example for AS_DIRNAME instead of referring to Posix..
6451 (File System Conventions): Put discussion of // versus / here, and
6452 modernize it a bit.
6453 (Limitations of Usual Tools): Add basename. Remove verbiage
6454 after dirname, since it got moved to the above sections.
6455 All this was inspired by a patch proposed earlier by Eric Blake.
6457 2006-03-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6967 (Coding Style): y is like s with respect to / and ,.
6968 (Limitations of Usual Tools): Document the weird restrictions
6969 that Posix has about { }. Use better quoting.

7057 Factor functionality to..
7058 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
7059 `AC_SUBST($1)' in the public version.
7060 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
7061 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

7109 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
7111 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
7112 AC_LANG_PROGRAM, fixing a typo. Don't give details about
7113 the inner workings of AC_LANG_FUNC_LINK_TRY.
7114 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7115 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7116 by the function rather than ignoring it.
7117 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7118 comparing its address. Intel's interprocedural optimization was
7119 outsmarting the old heuristic. Problem reported by
7120 Mikulas Patocka.
7122 2005-10-19 Stepan Kasal <kasal@ucw.cz>
7124 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

7131 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7133 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7134 before removing it (chmod -R u+rwx); there are three instances of this.
7136 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7137 Stepan Kasal <kasal@ucw.cz>
7139 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7140 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7141 make its content writable before removing it. Remove an errorneous
7142 comment from the end, where the logs of the failed tests are copied
7143 to the main log file.
7145 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7147 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7148 in case the computer is too quick. Double quote the configure.ac
7149 snippets.
7151 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7152 problems if the testsuite were running too fast.
7154 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7156 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7157 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7158 (which belong to Xt, not X itself). See Debian bug 327655.
7159 * NEWS: Mention this.
7161 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7163 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7165 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7167 * config/move-if-change: Don't output "$2 is unchanged";
7168 suggested by Ben Elliston. Handle weird characters correctly.
7170 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7172 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7173 calls, so that the final expansion of this macro is shorter.
7174 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7175 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7176 the cleanup there. Use AS_VAR_* macros, to be more general.
7177 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7179 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7181 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7183 2005-09-01 Stepan Kasal <kasal@ucw.cz>
7185 * doc/autoconf.texi (Configuration Headers): Add an index entry
7186 for AH_HEADER.
7188 2005-08-26 Pavel Roskin <proski@gnu.org>
7190 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
7191 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
7192 running xmkmf.
7194 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7196 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7197 The previous patch didn't work, so try a better one.
7199 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7201 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7202 in the example. Reported by Bruno Haible.
7203 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7204 "if $undefined_var;" succeeds with my shell.
7206 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7207 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7208 but change the m4_divert_text to m4_divert_once.
7210 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7212 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7213 Work around bug in Solaris /usr/xpg4/bin/awk.
7214 The bug is present in at least Solaris 8 through 10.
7216 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7218 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7219 some evil values and relying on the fact that $* concatenates the
7220 parameters by the first character from IFS.
7222 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7223 Stepan Kasal <kasal@ucw.cz>
7225 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7226 first header appears, define AH_HEADER.
7227 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7228 Update limitations about when to call AC_CONFIG_HEADERS.
7229 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7230 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7231 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7232 ``Configuration Actions''; fix their index entries.
7234 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7235 options correctly. Process N-M as M-N if M is smaller than N.
7236 Process ranges correctly so that N-N will run only N.
7237 Sort and uniquify the tests that will be run. If there is more
7238 than one test, reinsert the banners for the tests.
7239 * tests/autotest.at (Keywords): Unmark XFAIL.
7241 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7243 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7244 before passing the macro name to AH_TEMPLATE.
7246 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7247 now opens log after option processing; in particular, --version
7248 and --help do not touch config.log.
7250 * Makefile.maint: Revert the change from 2005-08-12.
7252 2005-08-22 Stepan Kasal <kasal@ucw.cz>

7255 common code to...
7256 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
7258 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7260 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7261 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7262 Language cleanup.
7264 * doc/autoconf.texi (Defining Symbols, Changed Results):
7265 Prepend to LIBS, not append, in examples.
7267 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7269 When building in place, set srcdir="."; suggested by Tim Van Holder.
7271 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7272 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7273 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7274 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7275 does not mean "no --srcdir option".
7277 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7279 * tests/autoscan.at (autoscan): New file.
7280 * tests/suite.at: Use it.
7281 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7282 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7284 * tests/autotest.at (Keywords): Test keywords combinations.
7286 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7288 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7289 add "2>&1"; gzip 1.2.4 prints help on stderr.
7291 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7293 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7294 was pushdef'ed twice while popped only once. Push it only once.
7295 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7297 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7299 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

7304 * Makefile.maint: Update from Bison.
7306 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7307 "<tab>" in comment, so that the point is understandable.
7309 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7311 Rewrite substantial part of lib/autoconf/status.m4.
7312 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7313 and CONFIG_COMMANDS are not processed in four separate loops.
7314 Instead, there is one main loop. This alows that the common code
7315 is expanded only once, thus config.status (and configure) is smaller.
7317 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7318 the AC_LIST_FILES and cousins macros are no longer used.
7320 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7321 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7322 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7323 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7324 contain the initialization, nor the for loop, nor the associated
7325 commands; all these go to ...
7326 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7327 _AC_OUTPUT_CONFIG_STATUS.
7328 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7329 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7330 (_AC_OUTPUT_FILE): The creation of the sed script ...
7331 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7332 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7333 _AC_OUTPUT_MAIN_LOOP.
7334 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7335 _AC_CONFIG_COMMANDS): Use ...
7336 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7337 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7338 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7339 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7340 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7341 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7342 ... new macros.
7343 (_AC_CONFIG_UNIQUE): Update.
7344 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7345 Replaced by this ...
7346 (_AC_LIST_TAGS): ... new common macro.
7347 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7348 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7349 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7350 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7351 this didn't belong to the `config commands' section.
7352 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7353 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7354 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7355 to the `config commands' section either.
7356 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7357 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7359 ... and many changes to the comments nearby.
7361 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7362 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7363 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7364 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7365 (#define header templates): The comment at the top of the generated
7366 header now includes the name(s) of the source file(s).
7368 Several unrelated small changes:
7370 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7371 parameter to AC_DIAGNOSE.
7372 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7373 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7374 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7375 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7376 with AU::AC_OUTPUT.
7377 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7378 in AC_OUTPUT doesn't double-quote it either.

7464 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

7474 configure_input, top_builddir, srcdir, etc.
7475 * lib/autotest/general.m4 (AT_INIT): Likewise, for
7476 PATH_SEPARATOR in AUTOTEST_PATH.
7478 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

7486 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

7544 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7545 addition.
7547 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

7569 because we really don't support spaces and suchlike in dir names.
7570 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7571 Don't worry about backslashes in srcdir; it can't happen now.

7600 (Special Shell Variables): Fix sed code this in the example.
7601 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
7602 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
7604 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
7605 expand to the empty list. Don't use two pairs of m4_changequote,
7606 it's not necessary.

7614 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
7615 * doc/autoconf.texi:
7616 Don't mention Solaris versions so much, if a
7617 problem is common to all extant versions of Solaris. Say "SunOS
7618 4" instead of "SunOS" for SunOS 4.
7619 (awk): Mention more of the limitations of traditional Awk.
7620 (cat): Don't talk about cat -v.

7653 quotes and backslashes. Patch from Derek Price.

7662 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7663 -u, since it outputs chatter if the input files are the same.
7664 Problem reported by Ralf Menzel.
7666 2005-06-08 Derek Price <derek@ximbiot.com>
7668 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7669 renaming them since they are about to be redefined anyhow.
7671 2005-06-08 Derek Price <derek@ximbiot.com>

7680 * doc/autoconf.texi (Introduction): Likewise.
7681 Reword to avoid some formatting glitches.

7684 Redo example output tp match current CVS snapshot.
7685 Use @example.org in email addresses when the examples
7686 might get inadvertently cut-and-pasted into user code.
7687 Remove example of autom4te usage that doesn't seem to work now.
7688 Use modern AC_INIT (except when the example is meant to be
7689 shown with Autoconf 2.13).
7690 Update ksh info for Solaris 9 and later.
7691 KB -> kB.

7703 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7704 Tru64 ksh pattern matching bug. Reported against Libtool by
7705 Albert Chin <libtool@mlists.thewrittenword.com> and
7706 Nicolas Joly <njoly@pasteur.fr>.
7708 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7710 m4_cdr of one-member list was [[]] (one-member list containing an
7711 empty string) instead of [] (an empty list. Callers were skewed to
7712 match this misbehaviour. As a consequence of this:
7713 - m4_foreach([x], [], [foo]) expanded to `foo', while
7714 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7715 This bug has been fixed:
7717 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7718 expand to an empty string; print error msg if called without
7719 an argument list.
7720 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7721 misbehaviour; handle [] and [[]] correctly.

7731 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7732 swallow records with more than 99 fields.
7733 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7734 parse the long line.
7736 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7738 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot

7751 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).

7771 2005-05-31 Dan Manthey <dan_manthey@partech.com>
7773 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7774 now contain newlines, and substituted files must be referenced on
7775 a line alone; the sed scripts to substitute them are now very
7776 different.

7792 classes in shell scripts. The test was too brittle.
7794 2005-05-25 Stepan Kasal <kasal@ucw.cz>
7796 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

7841 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7843 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
7844 of confdefs.h .
7846 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7848 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7849 argument to m4_foreach. I guess it was necessary in the past,
7850 but I think it's a no-op now.
7852 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7854 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7855 ``cat <<_ACEOF'' commands to one.
7856 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
7857 * lib/autoconf/status.m4: On various places, use expr instead of
7858 ``echo|sed.''
7859 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
7860 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
7861 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
7862 a range.
7863 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
7864 the wrong patterns between ``case'' and ``esac.'' The previous
7865 code had false positives.
7867 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
7869 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
7870 as on 2005-05-02.
7871 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
7872 Mention LIBOBJDIR.

7910 Update FSF postal mail address.
7912 2005-05-13 Stepan Kasal <kasal@ucw.cz>
7914 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
7915 check.
7916 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
7917 enough arguments, similarly as in m4_bpatsubsts.
7919 2005-05-12 Stepan Kasal <kasal@ucw.cz>
7921 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
7922 of absolute paths.
7924 2005-05-11 Stepan Kasal <kasal@ucw.cz>
7926 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
7927 for absolute directory names in one loop.
7928 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
7929 abbreviations of --version and --debug.
7931 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
7933 * doc/autoconf.texi (Autoconf Language): Be more precise about
7934 quoting rules. Problems noted by Stepan Kasal.
7935 Also, throughout this document, be more careful about white space.
7936 "blank", "white space", and "space" all have different meanings
7937 and we should be careful to say what we mean.
7939 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
7941 Fix C++ related problems reported by Werner Lemberg.
7942 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
7943 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
7944 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
7945 avoid problems with C++ and throw.
7946 * tests/compile.at: .cpp, not .cc.
7948 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
7950 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7952 * doc/autoconf.texi (Generic Functions): Typos.
7954 2005-05-02 Gary V. Vaughan <gary@gnu.org>
7956 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
7957 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
7958 set by latest automake.
7960 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7962 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
7963 outputs 0 on GNU/Linux these days.
7965 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
7967 * doc/autoconf.texi (Autoconf Language): Add more description
7968 about quoting heuristics.
7969 (Limitations of Builtins): Describe "set -" problems.
7971 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7973 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
7974 not newline.
7976 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
7977 by AC_DEFINE; it was a mistake.
7978 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
7980 2005-04-25 Stepan Kasal <kasal@ucw.cz>
7982 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
7984 2005-04-22 Stepan Kasal <kasal@ucw.cz>
7986 * doc/autoconf.texi (External Software): Quadrigraphs are not
7987 processed correctly in AS_HELP_STRING; avoid this in the examples.
7988 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7989 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7990 comment and reduce m4_default([foo], []) to [foo].
7991 (m4_strip): Update the explanation.
7993 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
7995 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
7996 Remove core.conftest.* too; it's generated by Tru64 5.1.
7997 Problem reported by Jennis Pruett.
7998 * lib/autoconf/functions.m4
7999 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8000 Don't bother to remove core files; AC_RUN_IFELSE should do that
8001 for you.
8003 2005-04-19 Stepan Kasal <kasal@ucw.cz>
8005 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
8007 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
8009 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.

8012 2005-04-15 Stepan Kasal <kasal@ucw.cz>
8014 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
8015 the comment.
8017 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
8019 * doc/autoconf.texi (External Software, Package Options): Add
8020 examples showing how to implement --with-* and --enable-* options.
8022 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8024 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
8025 as well as configure.in. Problem reported by Gregorio Guidi.
8027 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
8029 * doc/autoconf.texi (Particular Functions): Use gnulib's current
8030 pattern for alloca snippet.
8032 2005-04-04 Stepan Kasal <kasal@ucw.cz>
8034 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
8036 2005-04-01 Stepan Kasal <kasal@ucw.cz>
8038 * doc/autoconf.texi (Generic Programs): Fix a typo.
8040 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
8042 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
8043 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
8045 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8047 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8048 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8049 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8050 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8051 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8053 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8055 * NEWS: The configure command now warns you if you attempt to use
8056 a directory whose name contains a special character like space,
8057 newline, or "\".
8058 * doc/autoconf.texi (Installation Directory Variables): Allow
8059 "," in file names. Do not use \@; it's not a portable regexp.
8060 * bin/Makefile.am (edit): Likewise.
8061 * lib/Makefile.am (edit): Likewise.
8062 * tests/Makefile.am (edit): Likewise.
8063 * tests/semantics.at: Likewise.
8064 * tests/torture.at: Likewise.
8065 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
8066 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
8067 * doc/autoconf.texi (File System Conventions): Warn about
8068 unportable file names.
8069 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8070 (AC_INIT): Use it.
8071 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8072 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8073 ac_pwd, and quote srcdir.
8074 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8076 * doc/autoconf.texi: Fix some systematic formatting problems.
8077 ".)" needs a following @: if not at the end of a sentence, and
8078 similarly for "!)". "etc." should be preceded by a comma.
8079 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8081 2005-03-22 Bruno Haible <bruno@clisp.org>
8083 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8084 argument is often called 'build-aux'.
8086 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8088 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8089 macro AC_TRY_LINK is obsolete.
8090 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8091 `AC_CONFIG_FILES'.
8093 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8095 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8096 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8097 from a Common Lisp's `cl'.
8098 (AC_PROG_CXX): Behave according to the documentation: don't
8099 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8100 make the variable CCC precious; use `cl.exe', not `cl'.
8102 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8103 Alexandre Duret-Lutz <adl@gnu.org>
8105 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8106 /dev/null, as "configure" shouldn't read stdin, and this insulates
8107 us from problems (e.g., when testing for "cl"). Also, do this
8108 redirection before invoking "hostname" or "uname", and keep the
8109 original input stream available via...
8110 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8111 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8112 bother with "</dev/null" since it's now done at the top of
8113 'configure'.
8114 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8115 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8116 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8117 * doc/autoconf.texi (File Descriptor Macros): New section.
8118 (Printing Messages): Mention it.
8119 * tests/base.at (Input/Output): New test.
8121 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8123 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8124 newline if neither \c nor -n work, as that would output two
8125 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8127 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8129 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8130 This causes that any required macros inside will get before the if.
8131 * doc/autoconf.texi (autom4te.cache): A typo.
8133 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8135 Undo previous change, except keep the change to
8136 lib/autoconf/programs.m4 that replaced grep with shell
8137 pattern-matching. This is because net-snmp configure reads stdin.
8138 Reported by Noah Misch.
8140 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8142 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8143 from /dev/null, as "configure" shouldn't read stdin, and this
8144 insulates us from problems (e.g., when testing for "cl").
8145 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8146 before invoking "hostname" or "uname".
8147 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8148 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8149 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8150 "</dev/null" since it's now done at the top of 'configure'.
8151 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8152 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8153 Also, replace grep with shell pattern-matching, to save a process.
8155 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8157 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8158 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8159 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8160 compiler.
8162 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8164 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8165 grep -q isn't portable. Improve grep -s explanation.
8166 Problem reported by Dan Manthey.
8168 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8170 * doc/autoconf.texi (Special Shell Variables): Clarify
8171 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8173 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8175 * doc/autoconf.texi: Use @acronym for DJGPP.
8176 Fix some @code's that should have been @env's, and vice versa.
8177 Sort environment variable names.
8178 Mention that shells no longer inherit IFS.
8179 Don't recommend PATH_SEPARATOR=';' so strongly.
8180 Mention that $RANDOM might expand to the empty string.
8181 "symlink" and "soft link" -> "symbolic link".
8182 Improve mktemp description (reported by Bruno Haible).
8184 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8186 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8187 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8188 Likewise.
8189 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
8190 Likewise.
8192 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8194 * NEWS: Mention AT_COPYRIGHT.
8196 * tests/local.at (AT_CMP): Use diff directly on input files rather
8197 than copying them.
8199 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8200 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8202 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8203 and Paul Eggert <eggert@cs.ucla.edu>
8205 * tests/autotest.at (Empty test suite): New test.
8206 * tests/torture.at (Substitute and define special characters)
8207 (Substitute a 2000-byte string, Define to a 2000-byte string)
8208 (Substitute a newline, Define a newline): New tests.
8210 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8212 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
8213 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8214 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8215 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8216 (Standard regular expressions): New test.
8217 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8218 excess test name quoting.
8219 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8220 CPPFLAGS to `configure' instead of setting it in `configure'.
8222 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8223 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8224 on some platforms.
8226 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
8227 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
8229 * tests/local.at (AT_CMP): New macro.
8230 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
8231 (AC_SAVE_STATE): Move environment grep...
8232 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
8233 (AT_CONFIG_CMP): New macro.
8234 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
8235 * tests/c.at (Extensions): Do not exit early.
8236 * tests/atlocal.in: Inherit $GREP.
8238 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
8239 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
8241 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
8242 (AC_COPYRIGHT): Factor header comment portion out and move into...
8243 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
8244 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
8245 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
8246 --version output.
8247 * tests/local.at: Add Autoconf test suite copyright notice.
8248 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
8250 2005-02-04 Bruno Haible <bruno@clisp.org>
8251 and Paul Eggert <eggert@cs.ucla.edu>
8253 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
8255 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
8257 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
8258 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
8260 Try not to generated lines of unlimited length, as POSIX places a
8261 2047-byte limit on line length of portable text files.
8262 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
8263 Use newline as a separator, not space.
8264 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
8265 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
8266 space.
8268 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8270 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to

8282 with --help or --version.
8283 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

8321 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8322 Update the long comment explaining it.
8324 m4_require no longer writes an ``is required by'' line to the
8325 execution stack. It contains only one bit of non-redundant
8326 information: that the macro was required, not called. And even
8327 this bit is useless in most situations: have you ever met a macro
8328 which both calls and requires the same macro?
8330 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8331 (_m4_defun_pro_outer): ... only via this macro, for the outermost

8339 * tests/m4sugar.at (m4_require): Expect output without the
8340 ``is required by'' messages.
8342 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8344 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
8345 rather than x for expr.
8347 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
8348 this is safe.
8349 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
8350 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

8365 config.h.in is always recreated when --force.

8369 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
8371 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
8373 * doc/autoconf.texi (Limitations of Builtins): Clarify that
8374 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
8376 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
8378 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
8379 Warn about newline stripping in `` and $(). Update Solaris
8380 version to 9.

8382 X insulates us from future changes to Posix.
8383 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
8384 stripping.
8386 2005-01-19 Stepan Kasal <kasal@ucw.cz>
8388 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

8405 reported by Michael Jennings via Daniel Reed; see
8406 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
8408 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
8410 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
8411 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update

8432 (_m4_divert_n_stack): New macro; the expansion is
8433 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
8434 otherwise.
8435 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
8436 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8437 stored in _m4_divert_diversion or _m4_divert_dump.
8438 (m4_divert_pop): When the parameter is given, compare the symbolic
8439 name with the last diversion pushed on the stack. Previously, the
8440 current diversion was compared with the numeric value of the
8441 diversion given as the parameter.
8442 (m4_require): If the macro hasn't been expanded yet, call ...
8443 (_m4_require_call): this new macro.

8476 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

8478 not essential. Reported by Magnus Therning.
8479 * tests/torture.at (autoreconf.): New banner.
8480 (autoreconf and non-AC configure): Rename to `Non-Autoconf
8481 AC_CONFIG_SUBDIRS'.

8529 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
8530 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

8657 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

8722 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>

8725 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
8726 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
8727 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
8729 2004-12-07 Stepan Kasal <kasal@ucw.cz>
8731 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous
8732 patch: extra "-l"s.
8734 2004-12-06 Paul Eggert <eggert@cs.ucla.edu>
8736 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Check libc before
8737 looking elsewhere for getmntent. Problem reported by Mark D. Baushke.

8740 2004-12-03 Stepan Kasal <kasal@ucw.cz>
8742 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
8743 out the common code to ...
8744 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
8745 value of the #define--default to 1, iff the macro was called
8746 with exactly one parameter.
8748 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
8750 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
8751 "char c = '\200';" rather than "char c = 0x80;" as the
8752 latter doesn't conform to the strict C standard due to
8753 overflow on signed char hosts.
8755 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
8756 to -qlanglvl=ansi. We don't want to disable extensions.
8758 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
8760 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
8761 (Using Autotest, testsuite Scripts, Writing testsuite.at):
8762 Reword slightly to avoid some English-language problems noted

8808 * doc/autoconf.texi (Autoconf Language): Explain that
8809 ``descriptions'' may not be double quotes.
8810 (Quotation Rule Of Thumb): Likewise.
8811 (Pretty Help Strings): Likewise; remove the wrong comment;
8812 simplify the examples and improve their quoting.
8814 2004-11-13 Stepan Kasal <kasal@ucw.cz>
8816 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
8817 the $1_found variable, don't test whether the file is executable;
8818 Both things are checked ...
8819 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
8820 the former ``test -f''.
8821 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
8823 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

8826 use cp -R instead.
8828 2004-11-10 Derek R. Price <derek@ximbiot.com>
8830 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
8831 limitations. Reorder paragraphs for clarity.
8833 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
8835 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
8836 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
8837 variants", "Unix", and some related minor wording fixups.
8839 (Shellology, Special Shell Variables): Document that the Zsh
8840 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks

8852 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
8854 * doc/autoconf.texi (auindex): New macro.
8855 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
8856 Problem reported by Stepan Kasal.
8858 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
8860 Fix problems reported by Andreas Buening in:
8861 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
8862 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
8863 in test makefile.
8864 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
8865 readable; it's not true in OS/2-emx.
8867 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
8869 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
8870 "/usr/include", clear ac_x_includes instead of leaving it as "no"
8871 (trivial change). Problem and patch reported by Andrew Church in:
8872 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
8874 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
8876 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
8877 three args in examples. Problem reported by Frederik Fouvry in:

8879 Also, fix some minor spacing and punctuation bugs.
8881 2004-09-02 Akim Demaille <akim@epita.fr>
8883 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and

8897 Version 2.59b.
8899 * README: Add advice about m4 1.4.2.
8901 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
8902 texinfo.tex for now (done by hand now).
8903 * Makefile.maint (wget_files, cvs_files):
8904 Remove ansi2knr.c; nobody uses it.
8905 (ansi2knr.c-url_prefix): Remove.
8906 (cvs-update): Fix test for failure. I don't know why it ever
8907 worked...
8909 * doc/autoconf.texi: Update URLs, some of which went stale.
8910 Use @uref rather than @href.
8912 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
8913 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
8915 * config/config.guess, config/config.sub, config/elisp-comp,
8916 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
8917 doc/fdl.texi, doc/standards.texi: Sync with master copy.
8919 * NEWS, TODO, configure.ac, bin/autoscan.in,
8920 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
8921 doc/install.texi, lib/Autom4te/Configure_ac.pm,

8925 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
8926 tests/tools.at, tests/torture.at:
8927 Use "file name" rather than "filename" or "path",
8928 to be consistent with the terminology of the GNU coding standards.
8930 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
8932 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
8933 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
8934 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
8935 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
8937 More fixes to support spaces in the name of the build directory.
8938 This isn't a complete fix but it's an improvement.
8940 * bin/autoconf.as (autom4te_options): New var.
8941 Use it instead of appending to AUTOM4TE, so that we can allow
8942 spaces in the build directory's absolute name.
8943 * bin/autoheader.in ($autoconf): Allow spaces in file names.
8944 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
8945 AT_CHECK_NOESCAPE): Likewise.
8946 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
8947 main program): Likewise.
8949 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
8951 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
8952 From Ralf Corsepius in:

8955 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
8957 * doc/autoconf.texi (Function Portability): Document isinf and
8958 and isnan. From a suggestion by Kevin Ryde.
8960 * lib/Autom4te/General.pm (END): Return correct exit status even
8961 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
8963 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
8965 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
8966 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
8967 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
8969 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
8971 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
8972 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
8973 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
8974 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
8975 * lib/autom4te.in (Automake-preselections): Preselect
8976 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
8978 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
8980 * lib/autom4te.in (Automake-preselections): Preselect
8981 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
8982 trace them.
8984 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
8986 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
8987 Tru64.
8988 * doc/autoconf.texi (Shellology): Mention BIN_SH.
8989 Document problem with "`""`" in pdksh POSIX mode.
8991 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
8993 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
8994 with pdksh, too. Problem reported by Patrick Welche via
8995 Gary V. Vaughan.
8996 * doc/autoconf.texi (Shellology): Note that set -o posix is
8997 useful for pkdsh, too.
8999 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9001 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9002 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9003 Don't fail if ENV or BASH_ENV is readonly.
9004 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9005 etc. are read only. Problem reported by Ludovic Courtes.
9007 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9009 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9010 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9011 (trivial change)
9013 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9015 * doc/autoconf.texi (File System Conventions): Warn about
9016 names like "aux". Problem reported by Eric Blake.
9018 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9019 by zero instead of array size, so that we can use any arithmetic
9020 constant expression (instead of requiring an integer constant
9021 expression). This allows us to test expressions like DBL_MAX <
9022 LDBL_MAX, which didn't conform to the C standard using the old
9023 method.
9024 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9025 now that we can do floating-point tests at compile time.
9027 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9029 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9030 and LDBL_EPSILON, as the resulting expression isn't an
9031 integer constant expression and violates the C standard.
9032 Problem reported by Nelson H. F. Beebe. Also, check
9033 for "L" suffix, and check that long double doesn't have
9034 worse range or precision than double, that mixed-mode
9035 arithmetic doesn't generate a diagnostic, that double
9036 constants fit in long double.
9038 2004-06-03 Kevin Ryde <user42@zip.com.au>
9040 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9041 malloc(0) and realloc(NULL,size).
9043 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9044 Bob Proulx.
9046 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9048 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9049 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9050 by Jim Meyering.
9052 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9054 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9055 can be rewritten using if-then-else. Suggested by Bruno Haible.
9057 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9059 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9060 Problem reported by Stepan Kasal.
9062 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9064 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9065 change). Patch reported by Ralf Wildenhues in
9066 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9068 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9069 function F exists if the compiler and linker let you compile an
9070 expression like (F != 0). Recent versions of GCC optimize away
9071 the reference to F in that case, since every function address must
9072 be nonzero, so the link succeeds even if F does not exist.
9073 Problem reported by Manu in
9074 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9076 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9077 "Unix". Many uses changed.
9078 (Limitations of Builtins): Explain better why the ! command isn't
9079 portable.
9081 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9083 * lib/autom4te.in (Automake-preselections): Preselect
9084 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9086 2004-05-19 Kevin Ryde <user42@zip.com.au>
9088 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9089 referencing AC_FUNC_STRERROR_R.
9091 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9092 note pessimistic assumption when cross compiling.
9094 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9096 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9097 (until 2004) invoked subcommands with sh -e, contra POSIX.
9098 Reported by Kevin Ryde.
9100 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9102 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9103 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9104 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9105 `test -f " /usr/bin/grep"', which _always_ failed.
9106 (AC_PROG_SED): Ditto bogus PATH fix.
9107 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9108 requires that grep correctly supports _multiple_ `-e' options, rather
9109 than stating only that grep should accept `-e'.
9111 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9113 Port to C99, which requires that 'exit' be declared.
9115 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9116 to ensure that stdlib.h is included.
9117 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9118 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9119 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9120 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9121 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9122 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9123 when using 'exit' in a test; C99 requires that 'exit' be declared.
9125 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9127 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9128 now prefers 'grep' implementations that accept -e.
9129 (Limitations of Usual Tools): Describe problems of traditional
9130 egrep and fgrep with long input lines, and of traditional grep
9131 with -e.
9132 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9133 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9134 All callers changed. Append /usr/xpg4/bin to the PATH, for
9135 Solaris.
9136 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9137 the user with complaints about multiple -e options.
9138 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9139 Define it with AC_PROG_GREP.
9140 * configure.ac (AC_PROG_GREP): Add.
9141 * lib/freeze.mk (GREP): New macro.
9143 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9145 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9146 a possible candidate only after all others fail, rather than
9147 consulting it first. This improves backward compatibility by
9148 better reflecting the way shell selection occurred in previous
9149 versions of Autoconf, and should help to avoid triggering latent
9150 problems in other packages, such as the one in Automake where zsh
9151 is not handled robustly:
9152 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9153 Although it is not Autoconf's responsibility to work around
9154 problems in Automake, it nevertheless makes sense to avoid
9155 introducing unnecessary incompatibilites.
9157 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9158 Gary V. Vaughan <gary@gnu.org>
9160 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9161 how deeply nested we are when a suitable tool is found, set the
9162 ac_path_TOOL_found flag.
9163 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9164 nested we are in this macro. Break out of all 3 nested loops if
9165 ac_path_TOOL_found is set.
9167 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9169 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9170 of the _AS_PATH_WALK loop too if GNU flavor is found.
9172 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9174 * doc/autoconf.texi (Limitations of Make): Update documentation
9175 for `$<'. New entry `Long lines', based on a report from Simon
9176 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9177 paragraph about DJGPP, based on a mail from Richard Dawe.
9179 2004-04-20 Paul Eggert <eggert@twinsun.com>
9181 * tests/c.at (C keywords): Don't assume that GCC supports
9182 "restrict" and "inline", as sufficiently-old GCC versions do not
9183 (also, GCC configured to be in pedantic C89 mode does not).
9184 Problem reported by Sumit Pandya in:
9185 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9187 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9188 consider -g to work if it generates warnings when plain compiles
9189 don't. Problem reported by Braden McDaniel in:
9190 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9192 * doc/autoconf.texi (Slashes): New section, to document a problem

9201 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9203 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9204 best tool so far counter rely on the tool path variable name to
9205 avoid checks for one tool being affected by the results of running
9206 the length check on a previous tool.
9208 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9209 match expression argument, as different greps have different
9210 regular expression flavours.
9211 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9212 literals.
9213 (AC_PROG_EGREP): Pass 'EGREP$'.
9214 (AC_PROG_GREP): Pass 'GREP$'.
9216 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9218 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9219 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.

9223 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9224 Types, Specific Compiler Characteristics, System Services,
9225 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9226 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9227 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9228 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

9239 2004-03-28 Paul Eggert <eggert@twinsun.com>
9241 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9242 now defines HAVE_DECL_TZNAME if it is declared, when
9243 HAVE_STRUCT_TM_TM_ZONE is not defined.
9244 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9245 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
9246 for HAVE_TZNAME.
9248 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
9250 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected

9258 H. F. Beebe for the bug report.
9260 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
9262 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
9263 quoted -cmdline argument in Portland Group compiler (bug
9264 reported by Jeffrey J. Barteet).
9266 2004-03-25 Kevin Ryde <user42@zip.com.au>
9268 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
9269 (Run Time): ... here, where it's now mentioned.

9273 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
9274 inherits from language Autoconf-without-aclocal-m4.

9290 AC_CHECK_TOOLS.
9291 (Specifying Names): Document the reason for these future
9292 behavioral changes.
9293 * tests/mktests.sh: Do not generate tests for the
9294 new macros.
9295 * NEWS: Document these changes.
9297 * doc/autoconf.texi: Avoid macros with unbraced arguments,
9298 they make TeX hang up.

9303 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
9304 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
9305 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
9306 vowel.

9312 2004-03-03 Paul Eggert <eggert@twinsun.com>
9314 * bin/Makefile.am (edit): Don't use $< in a context where
9315 POSIX doesn't require support for it. Use $@.in instead.
9316 Problem reported by Anthony N. Frasso in
9317 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
9318 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.

9323 from the next generation of Libtool.
9324 * lib/autom4te.in (Autoreconf-preselections): Ditto.
9326 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9328 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
9329 is not always thread-safe. Report from Nathanael Nerode.
9331 2004-02-18 Paul Eggert <eggert@twinsun.com>
9333 Fix a dependencies problem, stemming from a Autoconf 2.59 build
9334 problem on QNX reported by Stephen Rasku in
9335 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
9337 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
9338 $(m4sh_m4f_dependencies); this removes a FIXME.
9339 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
9340 (MAINTAINERCLEANFILES): Split into pieces,
9341 one per related section. Add $(srcdir)/wrapper.in.
9343 2004-02-09 Paul Eggert <eggert@twinsun.com>
9345 * doc/autoconf.texi (Setting Output Variables): Emphasize that
9346 AC_SUBST provides no portable way to escape literal newlines.
9348 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9349 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9350 Darwin uses -lcrt2.o and there's little point to cataloging all
9351 the system variants. Partial fix reported by Andreas Waechter in:
9352 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
9353 for bug reported by Nelson H. F. Beebe in:

9368 the behavior of the third argument.
9369 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
9370 correctly the behavior of the third argument. Document
9371 what the three macros that AU_DEFUN defines do. Fix
9372 warning message when the third argument includes $0

9375 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
9376 Eric Sunshine <sunshine@sunshineco.com>
9377 Paul Eggert <eggert@twinsun.com>
9379 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
9380 (AS_INIT): Output shell initialization there. Removed optional
9381 parameter. Expand _AS_SHELL_FN_SPY.
9382 (AS_INIT_WITH_SHELL_FN): Removed.
9383 (_AS_SHELL_FN_SPY): New macro.
9384 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
9385 macros.
9386 (AS_SHELL_SANITIZE): Remove loop to find better shell
9387 and documentation for the parameter.
9388 (_AS_DETECT_BETTER_SHELL): Move it here.

9391 (AS_REQUIRE_SHELL_FN): Require shell functions when
9392 it is used.
9393 (_AS_LINENO_WORKS): Put around braces, we do not
9394 trigger the bash bug anymore.
9395 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
9396 use AS_INIT_WITH_SHELL_FN.
9397 * bin/autoconf.in, tests/wrapper.in: Regenerated.
9399 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
9401 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

9403 is broken.
9404 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
9405 (AU_DEFUN): Honor the third parameter, create autoupdate
9406 macros with AU_DEFINE.
9407 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
9408 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

9410 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
9411 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

9427 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
9428 2003 (except 1997) to the list of copyright years. This undoes
9429 the 2003-05-22 change, which removed the older years from the list.
9430 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
9432 2004-01-27 Gary V. Vaughan <gary@gnu.org>
9433 Albert Chin-A-Young <china@thewrittenword.com>

9439 AC_PROG_GREP.
9440 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available

9443 _AC_PROG_GREP, and AC_PROG_SED.
9444 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
9445 longest input length accepted by a command.
9446 (AC_PROG_SED): Use it.
9447 * doc/autoconf.texi (Particular Programs): Document the changes.
9448 * NEWS: Updated.
9450 2004-01-27 Paul Eggert <eggert@twinsun.com>

9472 sources.
9474 2004-01-26 Paul Eggert <eggert@twinsun.com>
9476 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9477 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9478 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9479 not <inttypes.h>. Problem reported by Tim Mooney in
9480 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9481 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9482 Likewise.
9484 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9485 otherwise "make check" fails because it forbids cmp (I guess
9486 because cmp treats files as binary on DOS-like systems).
9488 * tests/mktests.sh: Update copyright date to 2004, since some tests
9489 have changed in 2004.
9491 2004-01-23 Gary V. Vaughan <gary@gnu.org>
9493 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
9494 non-truncating sed or gsed program in PATH.
9495 * tests/acprograms.at: Add it.
9496 * doc/autoconf.texi (Particular Programs): Document it.
9497 * NEWS: Updated.
9499 2004-01-15 Paul Eggert <eggert@twinsun.com>
9501 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9502 -std1 disables some useful extensions on Tru64. Problem reported
9503 by N. Lichtmaier in
9504 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
9506 2004-01-14 Paul Eggert <eggert@twinsun.com>
9508 * doc/autoconf.texi (Programming in M4sh): Document that
9509 AS_MKDIR_P succeeds if the destination is a symbolic link
9510 to an existing directory.
9511 (Limitations of Usual Tools): Note that mkdir -p might not
9512 succeed on symlinks to directories.
9514 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9516 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
9517 * bin/autoheader.in: Grammar fix in message.
9518 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
9519 Test for dir before calling mkdir -p. (trivial changes)
9521 2004-01-13 Eric Blake <ebb9@byu.net>
9523 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
9524 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
9526 2004-01-10 Jim Meyering <jim@meyering.net>
9528 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
9530 2004-01-09 Paul Eggert <eggert@twinsun.com>
9532 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9533 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9534 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9535 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9536 AC_COMPILE_IFELSE, since we now assume our caller invokes
9537 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9538 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9539 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9540 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9542 2004-01-07 Paul Eggert <eggert@twinsun.com>
9544 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9545 `"'...'"`, as it's confusing (and I suspect it may not work on
9546 some platforms). The code was incorrect anyway, as it assumed
9547 that \$ evaluated to itself in that context. Reported by
9548 Alexandre Duret-Lutz.
9550 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9552 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
9553 and _LT_AC_TAGCONFIG.
9555 2004-01-06 Paul Eggert <eggert@twinsun.com>
9557 * doc/autoconf.texi (One Macro Call): Fix an incorrect
9558 example, and add more examples. Reported by Eric Sunshine.
9560 2004-01-05 Paul Eggert <eggert@twinsun.com>
9562 * doc/autoconf.texi (Limitations of Usual Tools):
9563 Remove warning against "rm -fr" introduced yesterday; it
9564 was a false alarm.
9566 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
9567 autoscan, autoupdate, ifnames): Don't use chmod -w.
9568 * lib/Makefile.am (autom4te.cfg): Likewise.
9569 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
9570 "chmod -w".

9573 Paolo Bonzini <bonzini@gnu.org>
9575 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
9576 by doing lineno substitution only on lines containing "$LINENO".
9578 2004-01-04 Paul Eggert <eggert@twinsun.com>
9580 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
9581 Use "rm -f" to remove conftest.sed, not plain "rm".
9582 Bug reported by David Relson in
9583 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
9585 * Makefile.am (autom4te-update):
9586 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
9587 * Makefile.maint (my-distcheck, do-po-update): Likewise.
9588 * doc/autoconf.texi (Guidelines): Likewise.

9595 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
9596 srcdir): Likewise.
9597 * doc/autoconf.texi (Limitations of Usual Tools):
9598 Warn against "rm -fr".
9600 2004-01-03 Paul Eggert <eggert@twinsun.com>
9602 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9603 -c -o might not work. From a suggestion by Kevin Ryde.
9604 (C Compiler, Generating Sources, Limitations
9605 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9606 Don't put '-o' after non-options, as POSIX doesn't allow this.
9607 Mention that cc's name might be gcc or c89 or whatever.
9609 2004-01-04 Kevin Ryde <user42@zip.com.au>
9611 * doc/autoconf.texi: Add various further index entries.
9613 2003-12-29 Paul Eggert <eggert@twinsun.com>
9615 * bin/autoreconf.in (autoreconf_current_directory):

9620 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9621 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

9675 (&sizes): New.
9676 Use them.
9677 No longer rely on Gnus to inline the list of signatures: compute
9678 them on the fly.
9680 2003-11-24 Akim Demaille <akim@epita.fr>
9682 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can
9683 override some files.
9684 (Input): AC_CONFIG_AUX_DIR(aux) is a bad idea on DOS.
9685 From Debian Autoconf 2.58.
9687 2003-11-24 Akim Demaille <akim@epita.fr>

9751 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

9887 cross test.
9889 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
9891 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
9892 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

9897 --help output.

9908 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
9909 -mGLOB_options_string stuff for Intel ifc, which can cause
9910 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
9911 pattern-matching instead of grep.

9933 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
9934 cache variable instead of $G77 to decide whether to include -O2,
9935 since $G77 is specific to Fortran 77.

9939 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

9944 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
9945 arguments so that it can be used with syntax identical to
9946 AC_PROG_F77, and so that we can more easily decide to
9947 remove/deprecate the DIALECT optional argument in the future if it
9948 proves troublesome.
9949 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
9950 non-freeform-supporting compilers. Document freeform flags.

9957 2003-10-03 Akim Demaille <akim@epita.fr>
9959 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
9960 * bin/autoreconf.in (autoreconf_current_directory): Create the

9964 2003-10-03 Akim Demaille <akim@epita.fr>
9966 * configure.ac: Quotation and formatting changes.

10015 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10016 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
10017 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
10019 2003-09-26 Akim Demaille <akim@epita.fr>
10021 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10022 directory for AC_CONFIG_COMMANDS' first argument exists.
10023 This makes valid the invocation of _AC_SRCPATH that follows.
10024 Reported by Eric Sunshine.
10025 * doc/autoconf.texi (Configuration Commands): Adjust.
10027 2003-09-26 Akim Demaille <akim@epita.fr>

10030 Reported by Ralf Corsepius.
10032 2003-09-26 Akim Demaille <akim@epita.fr>
10034 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
10035 arguments.

10048 The test suite are sometimes assigning timings incorrectly.
10049 Reported by Henk Krus.
10050 Diagnosed by Nicolas Joly.
10052 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10053 AT_help_all.
10054 Instead of making AT_help a sequence of assignments to grow
10055 $at_help_all, just make AT_help_all be the growing contents of
10056 $at_help_all, and make a single assignment in...
10057 (AT_INIT): here.
10058 (at_times_skip): Flip the meaning and rename as...
10059 (at_times_p): this.
10060 (AT_INIT): When summarizing the test that ran, remove
10061 $at_times_file after use, and check it is present before trying to
10062 use it.

10070 (ifnames): chmod -w.
10071 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10072 executables, not bin/ executables! Otherwise all the magic needed
10073 to find non installed files is turned off. This caused a failure
10074 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10075 as found in its environment (sent by tests/autoreconf): pointing
10076 to bin/autom4te that could not find its files.
10077 * tests/mktests.sh: Force the replacement of generated files, for
10078 the sake of "mv" program that are interactive when overwriting a
10079 -w file.

10090 Trivial change to support GCC's configuration procedure.
10091 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
10092 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
10093 about inconsistency if the preprocessor is set to give errors for
10094 any warning.
10095 * doc/autoconf.texi (C Compiler Characteristics): Document this.
10097 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

10100 and XFile.pm from Automake.

10150 From a suggestion by Ian Lance Taylor in
10151 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
10153 2003-09-05 Paul Eggert <eggert@twinsun.com>
10155 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,

10173 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10175 Add support for newer Fortran dialects. The F77 interface is
10176 unchanged, and continues to support Fortran 77. New FC macros
10177 correspond to all the old F77 macros, with output variables FC,
10178 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10179 available dialect, but older dialects can be specified. There are
10180 new macros AC_FC_SRCEXT to set the source extension, and
10181 AC_FC_FREEFORM to accept free-form source files.

10208 2003-09-02 Paul Eggert <eggert@twinsun.com>
10210 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
10211 Document problems with timestamp resolution that 'make', 'cp -p', and
10212 'touch -r' have.
10214 2003-08-27 Akim Demaille <akim@epita.fr>
10216 * tests/m4sugar.at (cross_warning): Make sure to enable the
10217 output, so that we can track spurious m4sugar output.
10218 * tests/local.at: Require 2.57.
10219 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
10220 are defaulted by AT_CHECK anyway.
10221 Use AT_CHECK_AUTOM4TE.
10222 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
10223 missing dnl.
10225 2003-08-27 Akim Demaille <akim@epita.fr>
10227 * bin/autoheader.in: Issue the "Using auxiliary..." message only

10274 2003-08-22 Akim Demaille <akim@epita.fr>
10276 Output stack traces in warnings.
10278 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
10279 Replace the former...
10280 (m4_warn): Pass the call stack to _m4_warn.
10281 * bin/autom4te.in: Adjust to output the call stack.
10282 * tests/m4sugar.at (m4@&t@_warn): Adjust.
10284 2003-08-22 Akim Demaille <akim@epita.fr>

10289 2003-08-21 Akim Demaille <akim@epita.fr>
10291 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
10292 (&verbose): Remove.
10293 (&getopt): Adjust the note and verb channels, depending upon
10294 --verbose.
10295 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
10296 * bin/autoupdate.in: Adjust.
10297 Use &verb, not &verbose.
10299 2003-08-21 Akim Demaille <akim@epita.fr>
10301 * bin/autoheader.in (&parse_args): Use &parse_warnings and
10302 &parse_WARNINGS.
10303 ($help): Use Autom4te::ChannelDefs::usage.
10304 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10305 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10307 2003-08-21 Akim Demaille <akim@epita.fr>
10309 First stab at preserving warnings between calls to autom4te,
10310 including when the cache is used.
10312 There are still several issues: (i) there are too many runs of m4
10313 (one for include, one for warnings, and some more), (ii) warnings
10314 spreading on several lines are not handled gracefully, (iii) the
10315 code meant to have the call stack display for errors does not work
10316 (its handling should move from m4 to autom4te).
10318 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10319 Use them.
10320 (@preselect): Add m4_warn.
10321 ($exit_status): Remove, use $exit_code.
10322 ($help): Use Autom4te::ChannelDefs::usage.
10323 (&handle_m4): No longer define the m4_warnings.
10324 At each run, extract and report the warnings.
10325 Always cache the result, including if the exit status is on
10326 failure, since if nothing changes, we should result in the same
10327 failure, hence we can use the cache.
10328 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10329 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10330 Remove.
10331 (m4_warn): Redefine as a do-nothing: it is its invocation that
10332 matters, as warnings are now reported via traces.
10333 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10334 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10335 the latter reveals calls to the former.
10337 Adjust the tests.
10339 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
10341 2003-08-21 Akim Demaille <akim@epita.fr>
10343 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
10344 Use them.
10346 2003-08-21 Akim Demaille <akim@epita.fr>
10348 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
10349 forward order.
10350 * lib/Autom4te/ChannelDefs.pm: Doc typos.
10351 (&parse_warnings): Accept a list of warning requests.
10352 (&usage): Return a string, not a side effect.
10353 (cross): New warning category.
10355 2003-08-21 Akim Demaille <akim@epita.fr>
10357 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
10358 (&require_configure_ac): Accept an optional directory argument.
10359 ($configure_ac): Remove.
10360 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
10361 (&catfile): Remove.
10362 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
10363 * bin/autoscan.in: Adjust.
10365 2003-08-20 Akim Demaille <akim@epita.fr>
10367 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
10368 Reported by Alexandre Duret-Lutz.
10370 2003-08-20 Akim Demaille <akim@epita.fr>
10372 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10373 * bin/autom4te: Adjust.
10374 In particular, be Autoconf tools are really silent when properly
10375 working, bind the verbosity of the 'note' channel to $verbose.
10376 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10377 (&xsystem, &contents): Remove, since they are exported by...
10378 * lib/Autom4te/FileUtils.pm: this.
10379 More perldoc.
10380 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
10381 * lib/Autom4te/FileUtils.pm: here.
10383 2003-08-20 Akim Demaille <akim@epita.fr>
10385 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
10386 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
10387 from CVS Automake.
10389 2003-08-20 Akim Demaille <akim@epita.fr>
10391 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
10392 (autom4te-update): New.
10393 * Makefile.cfg (update): Bind autom4te-update.
10395 2003-08-19 Derek Price <derek@ximbiot.com>
10397 * lib/autotest/general.m4: Comment various HELP_* diversions.

10401 package specific options and associated help.
10403 2003-08-19 Akim Demaille <akim@epita.fr>

10419 * doc/autoconf.texi (autom4te Invocation): Mention
10420 Autoconf-without-aclocal-m4.

10434 STDOUT & STDERR arguments.
10436 2003-08-14 Derek Price <derek@ximbiot.com>
10438 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
10439 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
10440 shorter column three. Add DESCRIPTION to log file content.
10442 2003-08-13 Derek Price <derek@ximbiot.com>
10444 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
10445 output.

10449 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
10450 (AT_CHECK_NOESCAPE): Move core functionality to...
10451 (_AT_CHECK): ...this new macro.
10453 2003-08-07 Derek Price <derek@ximbiot.com>
10455 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
10456 (AT_CHECK_NOESCAPE): ...to this new macro.
10458 2003-07-31 Paul Eggert <eggert@twinsun.com>
10460 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
10461 in Bash 2.01. Problem reported by Brian Gough in
10462 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
10464 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
10466 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
10467 -lcrt1.o, for OS X. (trivial change)
10469 2003-07-07 Paul Eggert <eggert@twinsun.com>
10471 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
10472 inside '#ifndef __cplusplus'. Problem reported by
10473 Bob Friesenhahn.
10475 2003-07-06 Bill Clarke <llib@computer.org>
10477 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
10478 'long', not 'int', for benefit of Sun's recent C++ compilers
10479 (trivial change). See:
10480 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
10481 (This really should be 'intptr_t', not 'long', but that would
10482 take more work.)
10484 2003-06-25 Akim Demaille <akim@epita.fr>
10486 * lib/Makefile.am (autom4te.cfg): Make it read only.
10487 Depend on Makefile since it contains substitutions.
10488 From Paolo Bonzini.
10489 * lib/autom4te.in (args): Add local.at? for Autotest args.
10490 This change was made on autom4te.cfg which is generated.
10491 Reported by Raja R. Harinath.

10496 From Gareth McCaughan.
10498 2003-06-23 Akim Demaille <akim@epita.fr>
10500 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10501 not all of them. This fixes 1. the fact that when testing
10502 Autoconf there are many many config.log, 2. the incorrect use of
10503 top_srcdir to find config.log.
10504 Don't mix the detailed output of failed test with the summary of
10505 failures. Rather, append detailed log afterwards.
10507 2003-06-23 Akim Demaille <akim@epita.fr>
10509 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

10514 * tests/torture.at (#define header templates): Don't use quotes in
10515 C++ comments as it puzzles Emacs' sh font-lock-mode.
10517 2003-06-23 Akim Demaille <akim@epita.fr>
10519 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
10520 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
10521 * tests/atspecific.m4: Rename as...

10530 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
10531 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
10532 ensuring we add -std1 for full-ANSI.
10534 * doc/autoconf.texi (hdrindex): New macro.
10535 Add index entries for portability of various standard header files.
10537 2003-06-20 Akim Demaille <akim@epita.fr>
10539 * configure.ac: Bump to 2.57b.
10541 2003-06-20 Akim Demaille <akim@epita.fr>

10545 2003-06-20 Akim Demaille <akim@epita.fr>
10547 * bin/autom4te.in: Don't rely on $HOME being defined.
10548 Reported by Marc Espie as PR/233.

10552 * lib/autotest/general.m4: Use at_times_file only if used.
10553 From Nicolas Joly.
10555 2003-06-20 Akim Demaille <akim@epita.fr>
10557 * config/config.guess, config/config.sub, config/elisp-comp,
10558 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
10559 Update from masters.
10561 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
10563 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
10564 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
10565 (TEST_SCRIPT): New diversion.
10566 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
10567 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
10568 (AT_INIT): Support for expected failures.
10570 2003-06-02 Akim Demaille <akim@epita.fr>
10572 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space

10577 PODify.
10579 2003-05-28 Paul Eggert <eggert@twinsun.com>
10581 * NEWS, doc/autoconf.texi (Particular Functions),
10582 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
10583 is the inverse of localtime.
10585 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
10587 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
10588 (handle_exec_errors): New function. Work around $! being
10589 altered by WEXITSTATUS.
10590 (xqx, xsystem): Use handle_exec_errors.
10592 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
10594 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
10595 Do not call `_exit()', simply modify `$?'.
10596 (xsystem): Reset $! before running system, and check it afterward.
10597 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
10598 63 for version mismatches.
10600 2003-05-23 Akim Demaille <akim@epita.fr>
10602 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10603 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10604 the middle of a line).
10605 * lib/m4sugar/m4sugar.m4: Likewise.
10606 Remove useless spaces in comments.
10608 2003-05-23 Akim Demaille <akim@epita.fr>
10610 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
10611 exit 63, so that we (or Automake's "missing") can tell the
10612 difference with a plain failure.
10613 * doc/autoconf.texi (Notices): Adjust.
10615 2003-05-23 Akim Demaille <akim@epita.fr>
10617 * Makefile.am, bin/Makefile.am, config/Makefile.am,
10618 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
10619 White spaces cleanup.
10621 2003-05-22 Jim Meyering <jim@meyering.net>
10622 Paul Eggert <eggert@twinsun.com>
10624 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10625 Remove `#include <stdlib.h>' from the list; we should never
10626 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10627 resulting namespace pollution would cause other tests to fail.
10628 Configure scripts run with some older versions of g++ and HP's
10629 aCC would fail due to such an #include. Problems reported by
10630 Matthew Mueller in <http://bugs.debian.org/120704> and by
10631 Keith Bostic in
10632 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10633 In the test, use the test declaration before including <stdlib.h>,
10634 as that's closer to how it'll be used.
10636 2003-05-23 Akim Demaille <akim@epita.fr>
10638 * doc/autoconf.texi (Header Portability): ucred.h.
10639 From Ian Redfern.
10641 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10643 Overhaul Autotest's logging: generate separate log files
10644 in testsuite.dir/NNN/testsuite.log, and append them to
10645 testsuite.log instead of re-running the test verbosely.
10647 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10648 file descriptor, write 0 to at_status_file instead of setting
10649 at_status=0, initialize some new variables (at_status_file,
10650 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10651 to rerun the tests, instead append the at_group_log to the
10652 at_suite_log when a test fails.
10653 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10654 with the AS_MESSAGE_LOG_FD redirected to stdout.
10655 (AT_CLEANUP): save the output status in $at_status_file
10656 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10657 its original place.
10658 (AT_CHECK): since tests are run with a redirected stdout,
10659 and used to be re-run in verbose mode, turn some $at_verbose
10660 into echo, and don't redirect the output of testing stdout
10661 and stderr.
10663 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10664 the name of the debugging directory and information about
10665 its contents.
10667 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10669 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
10670 parameter.

10692 Whitespace clean up.
10693 Suggested by Jim Meyering.
10695 2003-05-22 Akim Demaille <akim@epita.fr>
10697 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
10698 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
10699 Reported by Jim Meyering.
10701 2003-05-22 Akim Demaille <akim@epita.fr>
10703 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

10736 2003-05-17 Akim Demaille <akim@epita.fr>
10738 * lib/autoconf/functions.m4: Use the default includes so that
10739 memcmp be declared before being tested.
10740 Reported by Sander Niemeijer.
10741 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.

10759 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10760 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
10761 them uniform, and more robust to Perl special characters.
10762 Reported by Martin Mokrejs.
10764 2003-05-14 Akim Demaille <akim@epita.fr>

10782 and truncate.
10784 2003-05-06 Akim Demaille <akim@epita.fr>
10786 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10787 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10788 by aclocal.m4 is changed it might require the importing of another
10789 m4 extension file, i.e., aclocal must be run.
10791 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
10792 (&parse_args): Use --force with aclocal if required and supported.
10793 (&autoreconf_current_directory): Use &run_aclocal.

10800 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
10801 argument instead of a file name, so that the request file remains
10802 open during the whole autom4te run.
10803 ($icache_file): New.
10804 (&freeze): Lock the $icache_file.
10806 2003-04-29 Derek Price <derek@ximbiot.com>
10808 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
10809 seperator with m4_append_uniq(). It doesn't work.
10810 (AT_CLEANUP): Add `;' to end of at_help_all.
10811 (AT_INIT): Allow --keywords to be specified more than once. When
10812 grepping $at_help_all for keywords, use the field and keyword
10813 seperators to ensure a complete keyword match. Alter at_prev handling
10814 to support the new --keywords behavior.
10816 2003-04-27 Karl Berry <karl@freefriends.org>
10818 * doc/autoconf.texi: Make the dir entries in the autoconf manual
10819 align better with others. I also made some of the individual
10820 entries on one line, for brevity and to make it easier for me to
10821 sort my dir-example file in the Texinfo distribution :).
10823 2003-04-12 Jim Meyering <jim@meyering.net>

10862 Use them.
10863 * doc/Makefile.am (CLEANFILES): Adjust.
10864 (TEXI2DVI): Make it --batch.
10866 2003-03-31 Derek Price <derek@ximbiot.com>
10868 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
10869 which removed the main loop.
10870 Thanks to Akim Demaille.
10872 2003-03-29 Akim Demaille <akim@epita.fr>

10888 header causes problems.
10890 2003-03-28 Akim Demaille <akim@epita.fr>
10892 * tests/torture.at (Configuring subdirectories): Require aclocal
10893 1.4, otherwise the test fails, as it does support configure.ac.

10896 2003-03-28 Akim Demaille <akim@epita.fr>
10898 * doc/autoconf.texi (C Compiler): `#line' portability.

10927 sense. Verbosify the diversion definitions comment.

10931 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to

10963 * doc/autoconf.texi (Limitations of Make): Remove the section
10964 about `$<' in inference rules, it was a bogus interpretation of
10965 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
10966 Tru64 make in the "target lookup" section.
10967 (Automake): Automake 1.5+ no longer requires special tools to be
10968 present on the developer's host.
10970 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
10972 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set

10988 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
10989 When constructing paths with IFS=:, quote the path. If we're
10990 constructing a DOS-style absolute path, we don't want to split it
10991 on the colon.
10993 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo

11008 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
11009 to fix a mismatch between example and discussion.
11011 2003-02-24 Kevin Ryde <user42@zip.com.au>
11013 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf

11021 2003-02-20 Akim Demaille <akim@epita.fr>
11023 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
11024 compiler says yeah, but preproc says nope, compiler is right.
11025 Conversely, prompt the reader to send a bug report to the
11026 maintainers of the package, not of Autoconf.
11028 2003-02-20 Klee Dienes <kdienes@apple.com>
11030 * bin/autoreconf.in (autoreconf_current_directory): Properly
11031 handle an empty aclocal.m4.

11037 From Larry Jones.
11039 2002-12-23 Paul Eggert <eggert@twinsun.com>
11041 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11042 innocuous variant befor including <limits.h> or <assert.h>. This
11043 works around a bug reported by Albert Chin: HP-UX 11i
11044 (and earlier versions) have a <limits.h> that declares
11045 gettimeofday and many other functions.
11047 2002-12-03 Paul Eggert <eggert@twinsun.com>
11049 Version 2.57.
11051 * NEWS, configure.ac: Update version.
11053 * doc/fdl.texi: Upgrade to FDL version 1.2.
11055 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
11056 nontrivially in main's body, so that f's external declaration is
11057 not optimized away in AIX. This should fix the bug reported by
11058 Martin Frydl in
11059 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11061 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11062 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11063 defined, to support freestanding compilers. This should fix the
11064 bug reported by Momchil Velkov in
11065 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11067 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11068 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
11069 obsolete AC_CHECK_TYPE. The missing empty arg was reported
11070 by Simon Josefsson in
11071 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
11073 * Makefile.maint (www-gnu): New macro.
11074 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
11075 the location has moved.
11077 2002-12-02 Martin Frydl <martin@systinet.com>
11079 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
11080 \(.*\) match is too long and there is something more to be checked.
11081 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
11083 2002-11-15 Akim Demaille <akim@epita.fr>
11085 Version 2.56.
11087 * config/install-sh: chmod +x.
11088 From Paul Eggert.
11089 * config/move-if-change: Indenting changes.
11090 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
11091 * configure.ac (AM_INIT_AUTOMAKE): here.
11092 Require 1.7.1.
11094 2002-11-14 Akim Demaille <akim@epita.fr>
11096 Version 2.55.
11098 * config/config.guess, config/config.sub, config/install-sh:
11099 Update from masters.
11101 2002-11-14 Akim Demaille <akim@epita.fr>
11103 * Makefile.maint: Sync with Bison, i.e.:
11104 (po-check): Scan .l and .y files instead of the
11105 .c and the .h files that they generate. This fixes the bug
11106 reported by Tim Van Holder in:
11107 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11108 Look for N_ as well as for _. Try to avoid matching #define for
11109 N_ and _.
11110 From Paul Eggert.
11112 2002-11-14 Akim Demaille <akim@epita.fr>
11114 * doc/autoconf.texi (C Compiler): Compiling several files at once.

11117 2002-11-14 Akim Demaille <akim@epita.fr>
11119 * doc/autoconf.texi (C Compiler): Solitary backslashes.
11120 From Paul Eggert and Albert Chin-A-Young.
11122 2002-11-14 Kevin Ryde <user42@zip.com.au>
11124 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11125 than assigning in main, to avoid HP cc +O3 optimizing it away.
11127 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
11129 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11130 option. Process --recheck after parsing all options. Pass -q
11131 option to configure on --recheck.
11132 (AC_OUTPUT): Pass -q from configure to config.status.
11133 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
11134 arguments to record.
11135 * doc/autoconf.texi (config.status Invocation): Document
11136 config.status -q option.
11138 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11140 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11141 Makefile.in if Makefile.am exists.
11142 (output): Strip `.am' from Makefiles. Don't
11143 output AC_CONFIG_FILES if no Makefiles were found.

11154 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
11155 declaration in extern "C" too.
11156 Reported by Roberto Bagnara.
11158 2002-11-06 Akim Demaille <akim@epita.fr>
11160 * tests/torture.at (Configuring subdirectories): Don't use grep
11161 -w.

11163 Reported by Ezra Peisach.
11165 2002-11-05 Akim Demaille <akim@epita.fr>
11167 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11168 Remove.
11169 We _have_ to stop using the old compatibility scheme that tried to
11170 avoid useless backslashes because Libtool 1.4.3 contains a
11171 AC_DEFINE([error_t], [int],
11172 [Define to a type to use for \`error_t' if it is not
11173 otherwise available.])
11174 We _have_ to quote the single quote and backslashes with \. The
11175 old compatibility scheme saw that ` was backslashed, and therefore
11176 did not quote the single quote. Hence before this patch, Autoconf
11177 was not compatible with Libtool.
11179 2002-11-04 Paul Eggert <eggert@twinsun.com>
11181 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
11182 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
11183 LC_NAME, LC_PAPER, LC_TELEPHONE.

11186 2002-11-04 Akim Demaille <akim@epita.fr>
11188 Version 2.54c.
11190 * Makefile.maint (update, cvs-update, po-update, do-po-update):

11192 * config/texinfo.tex: Update.

11197 from...

11200 Support -m/--make.

11216 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
11217 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
11219 2002-10-31 Akim Demaille <akim@epita.fr>
11221 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
11222 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
11223 Make variable, not a shell variable.
11224 Suggested by Bruno Haible.
11226 2002-10-31 Akim Demaille <akim@epita.fr>
11228 * bin/autom4te.in (load_configuration): Reject #args out of any
11229 language.

11247 2002-10-29 Paul Eggert <eggert@twinsun.com>
11249 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
11250 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
11251 Problem reported by Bruno Haible.
11253 2002-10-29 Akim Demaille <akim@epita.fr>
11255 * doc/autoconf.texi (Header Templates): Put also in words what the
11256 pictures says to assist free style readers.

11511 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
11512 are a few warnings.
11513 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
11514 Quote for Perl '' strings, not "".
11515 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
11516 strings.
11518 2002-10-22 Akim Demaille <akim@epita.fr>
11520 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
11521 characters is a syntax warning now.
11522 (_AS_QUOTE): Accept $2 as list of characters to quote.
11523 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
11524 Quote for Perl, not sh.
11525 * bin/autoheader.in: When $debug, report the file which is
11526 `do'ne.
11527 * tests/tools.at (autom4te, autoheader): Exercise @bar, not merely
11528 `@', to tickle Perl's lists.
11529 Reported by Carlos Velasco.
11531 2002-10-18 Akim Demaille <akim@epita.fr>
11533 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that
11534 missing included files _are_ errors.
11535 Thanks to Alexandre Duret-Lutz.
11536 * tests/tools.at (autom4te cache): Adjust.
11537 * tests/atspecific.m4 (AT_CHECK_AUTOM4TE): New.

11543 2002-10-17 Akim Demaille <akim@epita.fr>
11545 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.
11546 Fixes the `AC_ARG_VAR' test failures.
11547 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Don't use cmp.
11548 * lib/freeze.mk (check-forbidden-patterns): New.
11549 * lib/autoconf/Makefile.am, lib/autotest/Makefile.am
11550 * lib/m4sugar/Makefile.am (check-local): Use it to catch `cmp'.
11551 * doc/autoconf.texi (Limitations of Usual Tools): HP-UX' cmp and
11552 /dev/null.
11553 Reported months ago by H. Merijn Brand.
11555 2002-10-17 Akim Demaille <akim@epita.fr>
11557 * tests/tools.at (autoheader): Put randoms `@' to stress Perl.
11559 2002-10-16 Paul Eggert <eggert@twinsun.com>
11561 * Makefile.maint (wget_files): Remove ansi2knr.c.
11562 (ansi2knr.c-url_prefix): Remove.
11564 2002-10-16 Akim Demaille <akim@epita.fr>
11566 Because of caching, some files that no longer exist and are no
11567 longer required can still cause errors.
11568 Reported by Alexandre Duret-Lutz.
11570 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
11571 to frozen files in @ARGV, as @ARGV must remain being a list of
11572 files. Rather, at M4 call sites, use this...
11573 (&files_to_options): New function.
11574 (&freeze): Use &error.
11575 (&up_to_date): If a file that was included according to the cache
11576 is no longer there, then the output is out dated.
11577 (&main): Don't even check whether a file is up to date is anyway
11578 --force is given.
11579 * tests/tools.at (autom4te cache): New.
11581 2002-10-16 Akim Demaille <akim@epita.fr>
11583 * bin/autoconf.as: Kill dead options.
11584 * bin/autoupdate.in (&parse_args): Kill old options.
11585 * bin/autoreconf.in (&parse_args): Remove dead options.
11586 Factor some code.
11587 (&autoreconf): Report the directories we enter *and leave*, so
11588 that error messages can be easily located, and use GNU Make
11589 format, so that Emacs' compile mode understands us.
11590 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
11591 if some file was changed instead of `print'.
11592 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
11593 (&parse_args): Remove the dead options.
11594 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
11595 autoheader's quiet mode.

11600 2002-10-11 Akim Demaille <akim@epita.fr>
11602 No longer use CPP to check for the existing of headers: use CC to
11603 check for compilability.
11605 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
11606 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

11608 (AC_CHECK_HEADER): this.
11610 * lib/autotest/general.m4 (AT_INIT): Include the failed test
11611 numbers in the Subject suggestion.
11613 2002-10-11 Akim Demaille <akim@epita.fr>
11615 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
11616 Suggest using AC_CHECK_DECLS instead.
11618 2002-10-11 Akim Demaille <akim@epita.fr>
11620 * tests/torture.at (AC_ARG_VAR): Have configure report the value
11621 of `precious'.
11623 2002-10-11 Akim Demaille <akim@epita.fr>
11625 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
11626 file name to enable parallel executions.
11627 From Sam Varshavchik.
11629 2002-10-08 Akim Demaille <akim@epita.fr>
11631 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11632 aclocal invocation, as Gettext macros might not be visible to
11633 aclocal.
11634 Instead of blindly running autopoint, scan configure.ac (not the
11635 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11636 Reported by Paul D. Smith.
11638 2002-10-08 Paul Eggert <eggert@twinsun.com>
11640 Work around problems found when POSIXLY_CORRECT=1 is set.
11641 None of this seems to have anything to do with POSIX, really,
11642 but it's how Perl getopt works.
11643 * bin/autom4te.in (parse_args): Configure GetOpt with
11644 "permute", too.
11645 * doc/autoconf.texi (Invoking autom4te):
11646 --warning -> --warnings.
11647 * lib/autom4te.in: --warning -> --warnings.
11649 2002-09-28 Akim Demaille <akim@epita.fr>

11664 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
11666 2002-09-28 Akim Demaille <akim@epita.fr>
11668 * tests/torture.at (Configuring subdirectories): Be robust to
11669 users who use config.site to require for a cache: in this case,
11670 the two last configure runs, using two different sets of
11671 arguments, trigger a legitimate error.
11673 2002-09-28 Akim Demaille <akim@epita.fr>
11675 * tests/m4sh.at (Functions Support, Functions and return Support):
11676 New.

11683 (autom4te): Specify that the sources are in the $srcdir.
11684 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11686 2002-09-28 Akim Demaille <akim@epita.fr>
11688 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
11689 (tm_zone): Move their rules to...
11690 * lib/autoconf/types.m4: here, using AN_ macros.
11691 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
11692 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
11693 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
11694 * lib/autoconf/programs.m4: here.

11697 Use it.

11701 * lib/autoconf/autoscan.m4: New file.
11702 * lib/autoconf/autoconf.m4: Include it.
11703 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
11704 that were listed in the original autoscan.list.
11705 * lib/autoconf/headers.m4: Similarly with headers.
11706 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
11707 (.m4.m4f): Don't pass --prepend-include, since that's done by
11708 tests/autom4te itself.
11709 * lib/autoscan/Makefile.am: Include freeze.mk.
11710 (autoscan.list): New target --this file is no longer a source.
11711 (autoscan.pre): New file.
11713 2002-09-28 Akim Demaille <akim@epita.fr>
11715 * bin/autoscan.in (@kinds): Make them singular.
11716 Adjust all uses.
11717 (&init_tables): When --debug, report the list of rules to ease
11718 tracking changes in autoscan.list.
11719 * lib/autoscan/autoscan.list (function): Strip comments, sort.
11721 2002-09-28 Akim Demaille <akim@epita.fr>
11723 * lib/autoscan/functions, lib/autoscan/headers,
11724 * lib/autoscan/identifiers, lib/autoscan/makevars,

11726 * lib/autoscan/autoscan.list: this.
11727 * bin/autoscan.in (&init_tables): Adjust.
11729 2002-09-28 Akim Demaille <akim@epita.fr>
11731 * lib/autoscan/functions, lib/autoscan/headers,
11732 * lib/autoscan/identifiers, lib/autoscan/makevars,
11733 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
11734 `functions' line is now prefixed with `function:'.
11735 * bin/autoscan.in (&init_tables): Adjust.
11737 2002-09-28 Akim Demaille <akim@epita.fr>
11739 From now on, autoscan files must always map a macro name to a
11740 word: there is no `default' macro for autoscan.
11742 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11743 all.
11744 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
11745 explicit.
11747 2002-09-28 Akim Demaille <akim@epita.fr>
11749 * bin/autoscan.in (%c_keywords): Remove.
11750 (&used): Keep only track of the words we might be interested in.

11752 checks.

11779 2002-09-26 Akim Demaille <akim@epita.fr>

11782 Reported by Ralf Corsepius.
11783 * doc/autoconf.texi (autoreconf Invocation): Likewise.
11785 2002-09-26 Akim Demaille <akim@epita.fr>

11791 Separated Dependencies'.
11792 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11793 (ifnames, autoscan, autom4te): Un-factor into several rules.
11795 2002-09-25 Paul Eggert <eggert@twinsun.com>
11797 * BUGS (Interoperability bugs): New section. Mention libtool
11798 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
11800 2002-09-24 Paul Eggert <eggert@twinsun.com>
11802 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
11803 make handles suffix-rules differently from GNU make.

11834 reading config.log when the compiler is rejected.
11835 Suggested by Guido Draheim.
11837 2002-09-13 Akim Demaille <akim@epita.fr>
11839 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
11840 (chdir_init) might hang when stat'ing mounted directories.
11841 Reported by Vance Shipley.
11843 2002-09-12 Akim Demaille <akim@epita.fr>
11845 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not

11850 * doc/autoconf.texi (Defining Symbols): Present two different
11851 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the

11856 * doc/autoconf.texi: Review grammar and punctuation.

11861 grammatical typos.
11862 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
11863 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
11864 is obsolescent.
11866 2002-09-11 Akim Demaille <akim@epita.fr>
11868 * doc/autoconf.texi (Questions): Rename as...
11869 (FAQ): this.

11884 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
11885 `duplicates', since the algorithm was too naive and could keep
11886 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
11887 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
11888 Reported by Ralf Corsepius.
11889 * tests/torture.at (Configuring subdirectories): Exercise these
11890 cases.
11892 2002-09-09 Akim Demaille <akim@epita.fr>
11894 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when

11896 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
11897 directory is relative.

11910 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11911 (ifnames, autoscan, autom4te): Since we don't only depend on
11912 configure.ac variables (such as VERSION etc.), but also on prefix
11913 and so forth, depend on Makefile, not configure.ac.
11914 Reported by Alexandre Duret-Lutz.
11915 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11917 2002-09-05 Kevin Ryde <user42@zip.com.au>
11919 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
11920 doesn't seem to be confined to ia64, just say "some versions".
11922 2002-09-04 Akim Demaille <akim@epita.fr>
11924 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
11925 Automake 1.6c.
11926 * Makefile.am (maintainer-clean-local): Remove.
11927 (MAINTAINERCLEANFILES): Remove COPYING.

11937 * configure.ac: Bump to 2.53d.
11938 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11939 as of today, on Automake's team suggestion.
11941 2002-09-03 Akim Demaille <akim@epita.fr>
11943 Version 2.53c.
11945 2002-09-02 Akim Demaille <akim@epita.fr>
11947 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and

11953 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11954 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11955 Also, tweak grammar: s/make sure to/be sure to/.
11957 2002-09-02 Paul Eggert <eggert@twinsun.com>
11959 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11960 directory names are generally preferable to physical names.
11962 2002-09-02 Akim Demaille <akim@epita.fr>
11964 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11965 Reported by Raja R. Harinath.
11966 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11967 * bin/autoupdate.in: Use error instead of die.
11969 2002-09-01 Paul Eggert <eggert@twinsun.com>
11971 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11972 ordinary shell concatenation rather than echo+tr+sed command that
11973 runs afoul of a long-line-related sed bug in Solaris 8.
11975 * bin/autoheader.in (parse_args): --warning -> --warnings.
11977 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11978 stdout, as traditional "ls" does.
11979 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11980 _AC_COMPILER_EXEEXT_O): Likewise.
11981 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11983 * bin/autoconf.as: Add --prepend-include option. This patch was
11984 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11985 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11987 * bin/autoconf.in, configure: Regenerate.
11989 * doc/autoconf.texi (Special Shell Variables): Mention
11990 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11992 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
11993 MAILPATH and set PS1, PS2, PS4 to default values, to work
11994 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11995 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11996 the Autoconf documentation specifies; fall back to "unset" only if
11997 this fails. Use a shell for-loop for this rather than an m4 loop,
11998 to shorten the output script.
12000 2002-08-30 Paul Eggert <eggert@twinsun.com>
12002 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12003 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12004 for the CDPATH problem. Document PWD.
12005 (Limitations of Builtins): Document the problem that "cd $foo" and
12006 "ls $foo" may refer to different directories in shells conforming
12007 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12008 example, since the old example is now out of date.
12010 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12011 FOO" and "ls FOO" talk about different directories; this catches
12012 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12013 spaghetti.
12015 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12016 of rolling our own unset.
12017 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12018 in practice we needn't worry about CDPATH if unset doesn't work.
12020 * Makefile.in, aclocal.m4, bin/Makefile.in,
12021 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12022 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12023 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12024 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12025 tests/Makefile.in: Regenerate with Automake 1.6.3.
12027 * config/config.guess, config/config.sub, config/mkinstalldirs:
12028 Update.
12030 * configure: Regenerate with self.
12032 2002-08-30 Kevin Ryde <user42@zip.com.au>
12034 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12035 default output.
12037 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12039 * bin/autom4te.in (Request::load): Correctly test for "do" read
12040 failure.
12042 2002-08-29 Akim Demaille <akim@epita.fr>
12044 * lib/Autom4te/General.pm (&xqx): New.
12045 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12046 hand, which is not portable.
12047 (&error): New.
12048 * bin/autom4te.in: Use them.
12049 Use &error instead of die.
12050 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12051 Adjust.
12053 2002-08-17 Paul Eggert <eggert@twinsun.com>
12055 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12056 default list of compilers to try, since it was long ago superseded
12057 by the ksh fc builtin. Suggested by Steven G. Johnson.
12059 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12061 * doc/autoconf.texi (Invoking autom4te): End the option table,
12062 fixing a bug introduced by the previous patch.
12063 (Limitations of Make): Add a 'target lookup' subentry in the
12064 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12066 2002-07-29 Mark D. Roth <roth@feep.net>
12068 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12069 options and use $AUTOM4TE_PATH.
12070 * doc/autoconf.texi: Remove documentation of autom4te
12071 --include-envvar and --site-macro-subdir options and document
12072 use of $AUTOM4TE_PATH.
12073 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12074 arguments from each language section.
12076 2002-07-29 Paul Eggert <eggert@twinsun.com>
12078 * doc/install.texi: Include copyright symbol in copyright notice.
12080 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12081 Replace with:
12082 (AM_MAKEINFOFLAGS): New macro.
12083 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12084 * Makefile.am (INSTALL): Use the new macros.
12085 Use -o rather than --output, since "missing" does not grok --output.
12087 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12089 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12090 comments do not always work. Never trust the exit status of
12091 `make -k'.
12093 2002-07-24 Kevin Ryde <user42@zip.com.au>
12095 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12096 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12098 2002-07-23 Paul Eggert <eggert@twinsun.com>
12100 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12101 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12102 apparently treats PATH="nonexistent" as if it contained ".".
12103 Bug reported by Stefan `Sec' Zehl.
12105 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12107 * doc/autoconf.texi (Limitations of Make): Mention the special

12124 2002-07-18 Akim Demaille <akim@epita.fr>
12126 Version 2.53b.
12128 2002-07-18 Akim Demaille <akim@epita.fr>
12130 * config/config.guess, config/config.sub: Update.
12132 2002-07-18 Akim Demaille <akim@epita.fr>

12160 * lib/Autom4te/General.pm (find_file): Browse the directories in
12161 the order they are given.

12222 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
12224 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
12225 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,

12227 so that Emacs setups GNU style for perl-mode and cperl-mode.
12229 2002-06-27 Paul Eggert <eggert@twinsun.com>
12231 * config/install-sh: Quote $src. Prefer || to test's -o option,
12232 as per "Limitations of Builtins".
12233 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
12234 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
12236 * tests/mktests.sh: Use grep instead of fgrep, as per
12237 "Limitations of Builtins".
12239 2002-06-15 Paul Eggert <eggert@twinsun.com>
12241 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
12242 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
12243 so that we consistently test the just-built programs.
12244 * tests/wrappl.as: Likewise.
12246 2002-06-12 Paul Eggert <eggert@twinsun.com>
12248 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
12249 name, so that symlinks to 'autoconf' work properly. Bug reported
12250 by Bruno Haible.
12251 * bin/autoheader.in (AUTOM4TE): Likewise.
12252 * bin/autoreconf.in (autoconf, autoheader): Likewise.
12253 * bin/autoscan.in (autom4te): Likewise.
12254 * bin/autoupdate.in (autom4te): Likewise.
12256 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
12257 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
12258 on Solaris 2.5.1.
12260 2002-06-11 Andreas Schwab <schwab@suse.de>
12262 * doc/autoconf.texi: Add more dir entries.
12264 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
12266 * bin/autom4te.in ($cache): Don't define using `$me', the name
12267 of the cache should not depend on the name under which autom4te
12268 was installed.
12270 2002-06-07 Akim Demaille <akim@epita.fr>
12272 * tests/tools.at (autoconf: forbidden tokens, basic)
12273 (autoconf: forbidden tokens, exceptions): Adjust to the change of
12274 words in autom4te.in.
12276 2002-06-07 Peter Eisentraut <peter_e@gmx.net>

12281 2002-06-07 Akim Demaille <akim@epita.fr>
12283 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
12284 rename as...
12285 (AC_REPLACE_FNMATCH): this.
12286 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
12287 AC_FUNC_FNMATCH_GNU.
12289 2002-06-07 Akim Demaille <akim@epita.fr>
12291 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
12292 Rosetta Stone for Unix.
12294 2002-06-07 Akim Demaille <akim@epita.fr>
12296 * bin/autom4te.in (warn_forbidden): When rejecting a token,
12297 suggest m4_pattern_allow.
12298 Suggested by Adam J. Richter.
12300 2002-06-07 Akim Demaille <akim@epita.fr>
12302 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
12303 ac_config_libobj_dir.
12304 (AC_CONFIG_LIBOBJ_DIR): New.
12305 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
12306 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
12307 Use ac_config_libobj_dir to find the replacement files.
12308 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
12309 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)

12313 * tests/mktests.sh (ac_exclude_list): Don't check
12314 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
12316 2002-06-06 Paul Eggert <eggert@twinsun.com>
12318 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
12319 if ln doesn't work.
12320 * NEWS: Likewise.
12321 * doc/autoconf.texi (Configuration Links): Likewise.
12322 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
12324 2002-06-05 Paul Eggert <eggert@twinsun.com>
12326 * config/config.guess, config/config.sub, config/texinfo.tex:
12327 Update from masters.
12329 2002-05-29 Paul Eggert <eggert@twinsun.com>

12345 * doc/autoconf.texi (Particular Programs): Document them.
12346 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
12347 * NEWS: Likewise.
12349 2002-05-27 Paul Eggert <eggert@twinsun.com>
12351 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
12352 * NEWS, doc/autoconf.texi (Particular Types): Document it.
12353 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
12354 instead of AC_MBSTATE_T, which never existed.
12356 2002-05-23 Akim Demaille <akim@epita.fr>
12358 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
12359 version of Autoconf that is discussed.
12361 2002-05-22 Paul Eggert <eggert@twinsun.com>
12363 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
12364 from the default list of compilers to try. Suggested by
12365 Kate Hedstrom.
12366 * NEWS: Document the above.
12367 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
12369 2002-05-17 Paul Eggert <eggert@twinsun.com>
12371 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
12372 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
12373 This improves on an earlier suggestion by H. Peter Anvin.
12375 2002-05-16 Paul Eggert <eggert@twinsun.com>
12377 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12378 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12379 Both macros now accept an optional source-dir arg.
12380 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12382 * NEWS: Document this.
12383 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12385 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12386 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12387 not for GNU extensions; this undoes part of the 2000-11-03 change,
12388 reverting to 2.13-compatible behavior.
12389 Add new optional argument DIR.
12390 (AC_FUNC_FNMATCH_GNU): New macro.
12392 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
12394 2002-05-08 Paul Eggert <eggert@twinsun.com>
12396 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12397 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12398 and it causes a 'test' syntax error if it fails.
12399 Bug reported by Stephen Gildea.
12401 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12402 If prototypes are supported, use them to check this at compile-time,
12403 instead of trying to check it at run-time. If we must do a run-time
12404 check, assume that setvbuf is standard when cross-compiling, as
12405 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12406 Bug reported by Paul D. Smith.
12408 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12409 argument specifying location of getloadavg.c. This removes a
12410 FIXME. This idea was taken from Jim Meyering's implementation in
12411 textutils.
12412 * doc/autoconf.texi (Particular Functions): Document this.
12413 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12414 that's what the code does; this fixes a bug reported by
12415 Paul D. Smith.
12417 2002-05-03 Akim Demaille <akim@epita.fr>
12419 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12420 autopoint instead of gettextize.
12421 ($uses_alocal): Rename as...
12422 ($uses_aclocal): this.
12423 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12424 Suggested by Bruno Haible.
12426 2002-05-03 Akim Demaille <akim@epita.fr>
12428 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12430 2002-04-29 Paul Eggert <eggert@twinsun.com>
12432 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12433 files to be 1 second older; just set them to be the same time.
12434 Also, sleep 1 second after the first aclocal, to work around
12435 problems with sub-second time stamps on the input files.
12437 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12439 * doc/autoconf.texi: Mention "set -e -x" lossage
12440 under node "Limitations of Builtins".
12442 2002-04-29 Akim Demaille <akim@epita.fr>
12444 * doc/install.texi: Better wording for setting variables when
12445 running configure.
12446 From Christian Cornelssen.
12448 2002-04-29 Akim Demaille <akim@epita.fr>
12450 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12451 of lack of $LINENO support, then the test will compare the $LINENO
12452 in testsuite vs. the lineno in the test file. This is wrong, of
12453 course.
12454 Be sure to protect it.
12455 Reported by Patrick Welche.
12457 2002-04-25 Akim Demaille <akim@epita.fr>
12459 * doc/autoconf.texi (Obsolete Macros): Typo.
12460 Reported by Vladimir Volovich.
12462 2002-04-25 Akim Demaille <akim@epita.fr>
12464 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12465 than some of the input files, hence, on the second run of aclocal,
12466 if some of its input are younger, make them older.
12467 Suggested by Paul Eggert.
12469 2002-04-25 Akim Demaille <akim@epita.fr>
12471 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
12472 Thanks to Paul Eggert.
12474 2002-04-25 Akim Demaille <akim@epita.fr>
12476 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
12477 and ac_subst_vars be sh variables containing the list of
12478 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12479 DEFAULT diversion.
12480 (_AC_INIT_PREPARE): Use them to log them.
12481 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12482 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12483 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12484 _AC_SUBST_FILES and _AC_SUBST_VARS.
12485 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12487 2002-04-24 Akim Demaille <akim@epita.fr>
12489 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12490 autoheader, so that automake does not complain about a missing
12491 config.h.in that was to be created.
12493 2002-04-23 Akim Demaille <akim@epita.fr>
12495 * bin/autoheader.in (parse_args): --warning takes an argument.
12496 Fixes PR/220.
12498 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
12500 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
12501 and bb.out when cleaning up.
12503 2002-04-22 Akim Demaille <akim@epita.fr>

12511 2002-04-22 Akim Demaille <akim@epita.fr>
12513 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
12514 comma.
12515 Reported by Gregory Giannoni.
12517 2002-04-22 Akim Demaille <akim@epita.fr>
12519 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
12520 Fixes false failures on Darwin.

12545 Minor spelling and grammar fixes.
12547 * doc/autoconf.texi: Follow the outline suggested in the GNU
12548 Sample Texts sections of the Texinfo 4.2 manual. Most
12549 importantly, this makes sure that the copyright notices appear in
12550 all output formats. You probably need Texinfo 4.2 to generate
12551 the manual now.
12553 Fix some bugs when using "$@" when there might be zero positional
12554 arguments in cases where this matters.

12575 that is not portable to Zsh.
12577 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
12579 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
12580 from aclocal.m4 too.

12586 2002-04-10 Akim Demaille <akim@epita.fr>
12588 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
12589 workaround for ${1+"$@"}.
12590 * doc/autoconf.texi (Shell Substitutions): Explain it.
12591 From Oliver Kiddle and Peter Stephenson.
12593 Have M4sh perform minimal shell sanitizing.
12595 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
12596 part into...
12597 (_AS_PREPARE): this new macro.
12598 (AS_PREPARE): New.
12599 (AS_INIT): Invoke AS_SHELL_SANITIZE.
12600 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
12602 Adjust Autoconf and Autotest.
12604 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12605 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
12606 * lib/autotest/general.m4 (AT_INIT): Likewise.
12607 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
12608 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
12609 AS_SHELL_SANITIZE.
12611 Use this M4sh to generate Autoconf's shell scripts.
12613 * tests/wrapsh.as: New, precursor of wrapsh.in.
12614 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
12615 on Autotest and M4sh.
12616 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
12617 (wrapsh.in): New target.
12618 * bin/autoconf.as: New, precursor of autoconf.in.
12619 (autoconf.in): New target.
12621 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

12624 with indented comments in rules.
12626 2002-04-09 Andreas Schwab <schwab@suse.de>
12628 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
12629 ac_top_builddir when setting ac_abs_top_builddir.
12631 2002-04-06 Kevin Ryde <user42@zip.com.au>
12633 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
12634 (Portable Shell): Cross reference to Systemology.
12636 2002-04-05 Akim Demaille <akim@epita.fr>
12638 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
12639 directories when descending in a SUBDIRS.
12640 Reported by Ezra Peisach.
12642 2002-04-04 Andreas Schwab <schwab@suse.de>

12645 contains no literal separators.
12647 2002-04-03 Akim Demaille <akim@epita.fr>
12649 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
12650 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
12651 Use dnl, not the KILL diversion.
12652 Extracted from...
12653 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12654 (AC_CONFIG_LINKS): here.
12655 Adjust.
12656 Don't use the KILL diversion, as it kills spurious output, which
12657 results in failures being hidden.
12658 Use m4_defn where appropriate.
12659 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12660 after the second argument.
12661 Use m4_defn.
12662 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12663 syntax, as it is provided by M4sugar.
12664 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
12666 2002-04-03 Andreas Schwab <schwab@suse.de>
12668 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
12669 expanded if $# <= 2.
12671 * bin/autoreconf.in (autoreconf): Run automake after rerunning
12672 aclocal.

12679 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
12680 (_AC_COMPILER_OBJEXT): Use them.
12681 Fixes Debian #138666.
12683 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
12685 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
12687 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
12688 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
12689 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
12690 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
12691 (AC_C_CONST): Same.
12692 (AC_C_INLINE): Same.
12693 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
12694 * doc/autoconf.texi, NEWS: Document.
12695 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
12696 AC_C_CROSS.
12698 2002-04-02 Akim Demaille <akim@epita.fr>

12701 _AS_MKDIR_P_PREPARE.
12703 2002-03-28 Kevin Ryde <user42@zip.com.au>
12705 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12706 to avoid versions of HP C which don't allow that.
12708 2002-03-27 Paul Eggert <eggert@twinsun.com>
12710 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
12711 (AS_SHELL_SANITIZE): Invoke it.
12712 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
12714 2002-03-26 Akim Demaille <akim@epita.fr>
12716 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
12718 2002-03-26 Akim Demaille <akim@epita.fr>
12720 * doc/autoconf.texi (Introduction): The GNATS base moved.
12722 2002-03-25 Paul Eggert <eggert@twinsun.com>
12724 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12725 as POSIX requires, as it doesn't work with Zsh.
12726 * doc/autoconf.texi (Assignments): Document the problem.
12728 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12730 * doc/autoconf.texi (Limitations of Make): Mention more issue
12731 about VPATH, overriding of macros in sub-makes, and handling of
12732 SHELL.
12734 2002-03-21 Paul Eggert <eggert@twinsun.com>
12736 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12737 problem with here-document buffer boundaries.
12739 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12740 when reinvoking the shell, to work around problems with installers
12741 who put strange things like "cd" commands in their environments.
12743 2002-03-19 Akim Demaille <akim@epita.fr>
12745 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
12746 From Aaron Ucko.
12748 2002-03-19 Akim Demaille <akim@epita.fr>
12750 * bin/autoscan.in (scan_file): Specify the location in `&used'
12751 invocations.
12752 From Nicolas Joly.
12754 2002-03-19 Akim Demaille <akim@epita.fr>
12756 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
12757 From Nishio Futoshi.
12759 2002-03-19 Akim Demaille <akim@epita.fr>
12761 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
12763 2002-03-18 Paul Eggert <eggert@twinsun.com>
12765 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
12766 (Limitations of Usual Tools): Add mkdir section.
12768 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12769 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12770 back on AS_DIRNAME to compute prefixes otherwise; this is
12771 roughly what mkinstalldirs does. That way, we need not have
12772 our own filename disassembler. The old disassembler did not
12773 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12775 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12776 Create at_test_all by a series of assignments,
12777 not by a single assignment of a long string. The latter causes ksh
12778 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12779 presumably because of a buffer overrun.
12781 2002-03-14 Paul Eggert <eggert@twinsun.com>
12783 * lib/autotest/general.m4 (at_times_skip):
12784 Renamed from at_times. Now a boolean.
12785 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12786 says 'times: not found'.
12788 2002-03-14 Akim Demaille <akim@epita.fr>
12790 * bin/autoreconf.in (&study_gettextize): New.
12791 (&autoreconf): Handle newest gettextize.
12792 Rerun aclocal if needed.
12793 Suggested by Andreas Schwab.
12795 2002-03-13 Akim Demaille <akim@epita.fr>
12797 * doc/autoconf.texi (Special Shell Variables): More about IFS.

12801 * doc/autoconf.texi (Header Portability): New.
12802 Add information about stdint.h and inttypes.h from Paul Eggert.
12804 2002-03-13 Akim Demaille <akim@epita.fr>
12806 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
12807 -p'.
12808 From Bob Proulx.
12810 2002-03-12 Akim Demaille <akim@epita.fr>
12812 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
12813 m4_require.
12815 2002-03-11 Andreas Schwab <schwab@suse.de>
12817 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
12818 does not do it if --with-lispdir is given.
12820 2002-03-08 Akim Demaille <akim@epita.fr>
12822 Version 2.53.
12824 2002-03-08 Akim Demaille <akim@epita.fr>
12826 * doc/autoconf.texi (Subdirectories): Clarify that the
12827 subdirectory should exist.
12829 2002-03-08 Akim Demaille <akim@epita.fr>
12831 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
12833 2002-03-08 Akim Demaille <akim@epita.fr>
12835 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
12836 aliases the actual variables, and modifications of the former
12837 affect the latter.
12839 2002-03-08 Akim Demaille <akim@epita.fr>
12841 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
12842 because of C-c: have m4 output in tmp files, then mv them.
12844 2002-03-08 Akim Demaille <akim@epita.fr>
12846 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
12847 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
12848 * bin/ifnames.in: Copyright update.

12852 * doc/autoconf.texi (Invoking autom4te): New.
12854 2002-03-05 Akim Demaille <akim@epita.fr>
12856 * doc/autoconf.texi (Specifying Names): Clarification suggested by
12857 Kevin Ryde.
12859 2002-03-05 Akim Demaille <akim@epita.fr>
12861 Version 2.52i.
12863 2002-03-04 Akim Demaille <akim@epita.fr>
12865 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
12866 * lib/autoconf/general.m4 (AC_INIT): More informative error
12867 message for LIBOBJ.
12869 2002-03-04 Akim Demaille <akim@epita.fr>
12871 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
12872 parallel builds.
12874 2002-03-04 Akim Demaille <akim@epita.fr>
12876 * doc/autoconf.texi (Transforming Names): Equality between target
12877 and host is irrelevant.
12878 (Specifying Names, Canonicalizing): Remove all references to the
12879 backward compatibility hooks. Rather, collect them all into...
12880 (Hosts and Cross-Compilation): this new section.
12881 * doc/install.texi (System Type): Ditto.
12882 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12883 that `--host' implies cross-compilation.
12885 2002-03-04 Akim Demaille <akim@epita.fr>
12887 * doc/autoconf.texi (Evaluation Macros): New.
12888 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
12889 useless.
12890 (_m4_foreach): Define the variant with immediate evaluation so
12891 that it contains exactly the items, not an expression which
12892 evaluation is the current item.
12893 (m4_re_string, m4_re_word): Don't over quote them.
12895 2002-03-04 Akim Demaille <akim@epita.fr>
12897 Instead of having stacking `shift's evaluated at the end, let
12898 `foreach' loops immediately evaluate them.
12900 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12901 $*. This is the n-th time I change my mind, but hopefully this is
12902 the last...
12903 (m4_lquote): New.
12904 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12905 efficient.
12906 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12907 it was only a hack for m4_text_wrap.
12908 (m4_car2): Remove, replaced by...
12909 (m4_cdr): New.
12910 (_m4_foreach): Adjust.
12911 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12912 m4_bpatsubst for clarification.

12945 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
12947 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
12948 translate \r\n to \n.
12950 2002-02-07 Akim Demaille <akim@epita.fr>
12952 Version 2.52h.
12954 2002-02-07 Akim Demaille <akim@epita.fr>

12963 Fix Autoconf PR/207:
12964 AC_PREFIX_PROGRAM fails with dashed program names
12966 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
12967 variable when looking for the prefix program.
12968 Now it also works for shell variables.
12970 2002-02-07 Akim Demaille <akim@epita.fr>
12972 * doc/autoconf.texi (Limitations of Builtins): More about
12973 case/esac.

12977 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
12978 case/esac, some shells don't support it.
12979 Reported by Zack Weinberg.
12980 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
12982 2002-02-06 Akim Demaille <akim@epita.fr>
12984 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
12985 sure not to introduce newlines in at_groups.
12986 * lib/autotest/Makefile.am (autotest.m4f): Typo.
12988 2002-02-06 Akim Demaille <akim@epita.fr>
12990 * tests/torture.at (Configuring subdirectories): Skip if aclocal
12991 is not available.
12993 2002-02-05 Paul Eggert <eggert@twinsun.com>
12995 * doc/autoconf.texi (Specific Compiler Characteristics):
12996 Describe HP-UX cc bug workaround more accurately.
12997 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
12998 not unsigned long.
12999 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
13000 cross-compilers, too. This undoes some of the most recent change
13001 to this file.
13003 2002-02-05 Akim Demaille <akim@epita.fr>
13005 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
13006 to make sure they are up to date when `check' is run.
13008 2002-02-05 Akim Demaille <akim@epita.fr>
13010 * doc/autoconf.texi (Making testsuite Scripts): Document
13011 package.m4.

13015 * lib/freeze.mk: New.
13017 2002-02-05 Akim Demaille <akim@epita.fr>
13019 Implement `autom4te --freeze'.
13021 * bin/autom4te.in (&freeze): New.
13022 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
13023 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
13025 2002-02-05 Akim Demaille <akim@epita.fr>
13027 * bin/autom4te.in (&parse_args): Implement `frozen files are
13028 optional are the sum of the previous files on the command line'.
13029 Also, pass `--reload-state=' on them, so...
13030 (handle_m4): don't.
13031 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13032 (M4sh): Rely on M4sugar.
13033 (Autotest, M4sh, M4sugar): Use frozen files.
13035 2002-01-31 Akim Demaille <akim@epita.fr>
13037 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
13038 * doc/autoconf.texi (Initializing configure): Adjust.
13040 2002-01-30 Akim Demaille <akim@epita.fr>
13042 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
13043 alphanumeric to `-' instead of `_'.
13045 2002-01-30 Akim Demaille <akim@epita.fr>
13047 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
13048 for plain code, the other for cross-compilation code. The latter
13049 is now run with GCC only.

13055 values.

13063 Reported by Alexandre Duret-Lutz and Larry Schmitt.

13067 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13068 needs an argument.
13070 2002-01-28 Akim Demaille <akim@epita.fr>
13072 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13073 AUTOTEST_PATH *after* it was set.
13074 Don't put `.' in the PATH: the user should be precise and `./' if
13075 needed. In addition, given that the test suite does some `cd', if
13076 `.' is in the path, the `tested programs' sections will report
13077 programs found in the test suite's directory, while during the
13078 tests (performed in their own directory), these programs are no
13079 longer visible. In other words, the results is confusing and
13080 useless.
13081 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
13083 2002-01-24 Akim Demaille <akim@epita.fr>

13094 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
13095 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
13096 Bourne. Use /bin/sh.
13097 From Andreas Buening.
13099 2002-01-24 Akim Demaille <akim@epita.fr>
13101 * config/config.guess, config/config.sub, config/texinfo.tex:

13111 Automake.
13113 2002-01-24 Akim Demaille <akim@epita.fr>
13115 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
13116 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
13117 Reported by Geir Ove Myhr.
13119 2002-01-21 Akim Demaille <akim@epita.fr>
13121 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
13123 2002-01-21 Akim Demaille <akim@epita.fr>
13125 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13126 message on invalid options.
13127 * bin/autom4te.in (parse_args): Don't use
13128 Autoconf::General::getopt with non valid options.
13130 2002-01-17 Jim Meyering <meyering@lucent.com>
13132 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13133 $ac_cv_exeext so we don't use an old, invalid, cached value.
13135 2002-01-11 Akim Demaille <akim@epita.fr>
13137 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
13138 Meyering.

13140 limitation.

13144 2002-01-06 Akim Demaille <akim@epita.fr>
13146 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13147 package.m4, since is really depends upon configure.ac, not
13148 configure.
13149 * doc/autoconf.texi (testsuite Scripts): Adjust.
13150 * tests/Makefile.am (package.m4): New.
13151 EXTRA_DIST it since its a source.
13153 2002-01-06 Akim Demaille <akim@epita.fr>
13155 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13156 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13157 and PACKAGE_BUGREPORT from here...
13158 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13159 arguments.
13160 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13161 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13162 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13163 * tests/tools.at (autoheader): Adjust.
13164 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
13166 2002-01-06 Akim Demaille <akim@epita.fr>

13178 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13179 sometimes needing writable input.
13181 2001-12-17 Jim Meyering <meyering@lucent.com>
13183 * doc/autoconf.texi (New Macros): Tweak wording.
13185 2001-12-14 Akim Demaille <akim@epita.fr>
13187 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13188 trailing files, don't apply `-rf' to files which might not be
13189 created by configure (core, core.*, and *.core), but just `rm -f'.
13190 Suggested by Jonathan Kamens.
13192 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13194 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13196 2001-12-14 Akim Demaille <akim@epita.fr>
13198 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13200 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

13203 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13204 abs_srcdir, top_srcpath to abs_top_srcdir.
13205 (_AC_OUTPUT_FILES): Adjust.

13207 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13208 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13210 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13212 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13213 C/Fortran linking on HP/UX, by extracting the Fortran library
13214 search path from the LPATH line in the $F77 -v output.
13216 2001-12-12 Kevin Ryde <user42@zip.com.au>
13218 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13219 forbidden file descriptors table.
13221 2001-11-26 Akim Demaille <akim@epita.fr>
13223 * bin/autoscan.in (%c_keywords): Build it at top level.
13224 Map to 1 in order to simplify its uses.
13226 2001-11-26 Akim Demaille <akim@epita.fr>
13228 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13229 Remove $filepath, useless.
13230 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13231 variables, they are really part of the tokens.
13232 Split the input line on spaces and then look for tokens.
13233 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13234 because of `lex$U.$(OBJEXT)'.
13235 (&scan_files): Use "@list" instead of join.
13236 * doc/Makefile.am (CLEANFILES): Add *.fns.
13238 2001-11-26 Akim Demaille <akim@epita.fr>
13240 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13241 Remove, replaced by...
13242 * tests/wrappl.in: Be common for all the Perl executables.
13243 In particular autoscan and autoheader want -I.
13244 * configure.ac: Adjust.
13245 * lib/autoscan/headers: errno.h is portable.
13247 2001-11-26 Akim Demaille <akim@epita.fr>
13249 * bin/autoscan.in (used): New.
13250 Use it.
13252 2001-11-26 Akim Demaille <akim@epita.fr>
13254 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13255 directives.
13256 (&scan_sh_file): Remove a duplicate pattern.
13257 (&check_configure_ac): Use long options.
13258 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13260 2001-11-26 Akim Demaille <akim@epita.fr>
13262 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13263 Before, having a line containing the opening of a multi line
13264 comment made the whole line be ignored.
13266 2001-11-26 Akim Demaille <akim@epita.fr>
13268 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13269 (testsuite Scripts): Be one of its subsection.
13270 (Autotest Logs): New.
13272 2001-11-26 Akim Demaille <akim@epita.fr>
13274 Test groups are now run two directories deeper.
13276 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13277 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13278 at_top_builddir.
13279 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13280 top_srcdir, builddir and top_builddir.
13281 Use `at_*dir' relatively to the directory containing the
13282 suite, use `*dir' when relatively to the current group dir.
13284 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13286 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13287 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13288 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13289 spelling errors.
13291 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13293 * doc/autoconf.texi (Using System Type): Add an example of `case
13294 $host' usage so people quit using `case $target' everywhere.
13296 2001-11-22 Akim Demaille <akim@epita.fr>
13298 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13299 spotted by Jim Meyering.
13301 2001-11-16 Paul Eggert <eggert@twinsun.com>
13303 This patch implements a `long double' suggestion by Oliver Kiddle.
13305 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13306 static, to catch errors if the value isn't known at compile-time
13307 and the compiler supports dynamic arrays. Change its name from
13308 `_array_' to `test_array' to avoid potential name clashes.
13309 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13310 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13311 better than double. Catch a bug in GCC 2.95.2 x86.
13312 * doc/autoconf.texi (C Compiler): Document the above.
13313 * NEWS: Likewise.
13315 2001-11-13 Akim Demaille <akim@epita.fr>
13317 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13318 hand.
13319 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13321 2001-11-13 Akim Demaille <akim@epita.fr>
13323 * lib/autotest/general.m4 (AT_INIT): After having run the test
13324 group, go back to the initial directory, not to at_suite_dir.
13326 2001-11-13 Akim Demaille <akim@epita.fr>
13328 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13329 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13330 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13331 option.
13332 (AT_CHECK_CONFIGURE): Use absolute paths.
13333 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13334 The problem is still the old one: there is no means in M4 (that I
13335 know about) to create a defining macro, because there is no means
13336 to create `$1' etc., therefore, the defining macro ``swallows''
13337 all the arguments meant to the defined macro.
13339 2001-11-13 Akim Demaille <akim@epita.fr>
13341 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13342 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13343 configure.ac.
13344 * tests/aclocal.m4: Remove, as it is no longer used.
13346 2001-11-13 Akim Demaille <akim@epita.fr>
13348 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13349 variable names when referring to a single test group, or to
13350 `suite' when referring to the whole test suite.
13351 `at_last_test' is removed: m4 compute at_format itself.
13352 (at_stdout, at_stder1, at_stderr): New variables.
13353 (AT_CHECK): Use them.
13355 2001-11-13 Akim Demaille <akim@epita.fr>
13357 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13358 in PATH.
13359 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13360 Do it as soon as a test fails, don't wait till the end of the test
13361 suite.
13362 Don't remove $as_me.[0-9]*, since these files no longer exist.
13364 2001-11-13 Akim Demaille <akim@epita.fr>
13366 * tests/tools.at: Use absolute paths, since we are no longer run
13367 in place.
13369 2001-11-13 Akim Demaille <akim@epita.fr>
13371 Now that tests are running in their own private dir, there is no
13372 need to list the files to remove at the end of tests groups.
13374 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13375 (AT_data_files, at_data_files): Remove.
13376 (AT_CLEANUP, AT_DATA): Simplify.
13377 (AT_INIT): Adjust.
13378 Remove the group dir if !debug && !failed.
13379 * tests/atspecific.m4: Adjust.
13381 2001-11-13 Akim Demaille <akim@epita.fr>
13383 Start a new layout for Autotest: `testsuite' creates
13384 `testsuite.dir' in which the at-check-line etc. files are to be
13385 found, and `testsuite.dir/003' where the test group 3 is run.
13387 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13388 at_check_line_file, at_format, at_test_normalized, at_group_dir
13389 are new variables.
13390 Create the directories.
13391 Use absolute paths for at- files.
13392 (AT_CHECK): Adjust.
13394 2001-11-11 Michael Matz <matz@kde.org>
13396 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13397 (m4_car2): New.
13398 (m4_car): Properly quote arguments.
13400 2001-11-13 Akim Demaille <akim@epita.fr>
13402 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13403 with stricter rules on LIBOBJS.
13405 2001-11-12 Paul Eggert <eggert@twinsun.com>
13407 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13408 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13409 __PROTOTYPES too.
13411 2001-11-12 Akim Demaille <akim@epita.fr>
13413 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13415 2001-11-12 Akim Demaille <akim@epita.fr>

13420 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13421 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13422 specify to what the macro should be defined (typically to 1).
13424 2001-11-12 Akim Demaille <akim@epita.fr>
13426 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13427 From Jim Meyering.
13429 2001-11-12 Akim Demaille <akim@epita.fr>
13431 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13432 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13433 definition used by Automake where LEX is +/- "${missing} lex" and
13434 `missing' itself contains variables.
13436 2001-11-12 Akim Demaille <akim@epita.fr>
13438 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13439 Now that M4sh pushes BODY, the comments were output at the end of
13440 the test suites.
13442 2001-11-08 Akim Demaille <akim@epita.fr>
13444 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13445 that we can trace macros from aclocal.m4.
13446 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13447 obsoleted, and redirect to the former anyway.
13448 Reported by Ralf Corsepius.
13450 2001-11-08 Akim Demaille <akim@epita.fr>
13452 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13453 processed only if present.
13454 * tests/torture.at (Configuring subdirectories): Use autoreconf
13455 instead of successive calls to autoconf.
13456 Add a nonexistent subdirectory to exercise the patch above.
13457 Reported by Ralf Corsepius.
13459 2001-11-08 Kevin Ryde <user42@zip.com.au>
13461 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13462 doesn't accept .S files.

13470 (handle_output): Use it.
13471 Read m4_pattern_forbid with messages.
13473 2001-11-05 Akim Demaille <akim@epita.fr>
13475 * bin/autom4te.in (--normalize): Remove.
13476 * lib/autom4te.in: Adjust.
13478 2001-11-05 Akim Demaille <akim@epita.fr>
13480 * tests/Makefile.am (testsuite): Rename this target as...
13481 ($(TESTSUITE)): this.
13482 From Nicolas Joly.
13484 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13486 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13487 the --prefix option, also remove it's argument.
13489 2001-11-05 Akim Demaille <akim@epita.fr>
13491 * doc/autoconf.texi (testsuite Invocation): Update.
13492 (Writing testsuite.at): Update.

13500 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13501 (&file_name_is_absolute): New, wrappers around routines from
13502 File::Spec.
13503 Use and export them.
13504 (&find_configure_ac): Optionally take a directory where to look at.
13505 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13506 the arguments.
13507 Default @ARGV to `.', not find_configure_ac.
13508 (&autoreconf): Argument is a directory.
13509 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13510 * doc/autoconf.texi (autoreconf Invocation): Update.
13512 2001-11-03 Akim Demaille <akim@epita.fr>
13514 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13515 (@export_forward_subs): New.
13516 Add basename, dirname, and fileparse.
13517 (@EXPORT): Adjust.
13518 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13519 Don't look for aclocal flags if we already know aclocal is not
13520 used.
13521 Move aclocal.m4t only if it exists.
13522 Reported by Ezra Peisach.
13524 2001-11-03 Akim Demaille <akim@epita.fr>
13526 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13527 passed on command line, defaulting to ./configure.ac if present.
13528 (&maybe_autoreconf, File::Find): Remove, unused.
13529 (&autoreconf): If autoconf is not used, don't try to trace.
13531 2001-11-02 Akim Demaille <akim@epita.fr>
13533 * configure.ac: Bump to 2.52g.
13535 2001-11-02 Akim Demaille <akim@epita.fr>
13537 Version 2.52f.
13539 2001-11-02 Akim Demaille <akim@epita.fr>
13541 * config/config.guess, config/config.sub, doc/standards.texi:
13542 * config/lispdir.m4: Update from masters.
13543 * configure.ac: Bump to 2.52f.
13545 2001-11-02 Akim Demaille <akim@epita.fr>
13547 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13548 Don't run aclocal when aclocal.m4 is not from aclocal.
13549 From Ezra Peisach.
13550 Don't run libtoolize and gettextize if --install is not given.
13552 2001-11-01 Paul Eggert <eggert@twinsun.com>
13554 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13555 be invoked before _AS_LINENO_PREPARE.
13556 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13557 than character ranges.
13559 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13560 invoking AS_BASENAME. Set the locale variables to 'C' if
13561 possible, as POSIX requires this to get the traditional
13562 behavior.
13563 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13565 2001-10-31 Paul Eggert <eggert@twinsun.com>
13567 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13568 with {}, as that triggers a bug in Bash 2.05.
13570 (_AS_LINENO_PREPARE): Use Sed rather than
13571 Awk. Fix the sed prepass to work even if there are multiple
13572 instances of $LINENO on the same line. Do not substitute for
13573 other variables like $LINENOT. Do not check file dates; such a
13574 check is unreliable on sufficiently fast machines, and removing
13575 the check makes the code simpler and more reliable. Check for
13576 output and chmod failures.
13578 * doc/autoconf.texi (Special Shell Variables): Document
13579 the above.
13581 2001-10-31 Akim Demaille <akim@epita.fr>
13583 * tests/Makefile.am (atconfig): Remove this target, Automake
13584 handles it now.
13586 2001-10-31 Akim Demaille <akim@epita.fr>
13588 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13589 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13590 provided, while it is optional.
13591 * configure.ac: Adjust.
13593 2001-10-26 Paul Eggert <eggert@twinsun.com>
13595 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13596 lib/Autom4te/Struct.pm:
13597 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13598 with 5.005_02.
13600 * doc/autoconf.texi (Special Shell Variables): Document some
13601 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13603 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13604 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13605 eval $LINENO is not portable in practice.
13607 2001-10-24 Akim Demaille <akim@epita.fr>
13609 * lib/Autom4te/General.pm (backname): New.
13611 2001-10-24 Akim Demaille <akim@epita.fr>
13613 * m4/: Remove, merged into...
13614 * config/: here.
13616 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
13618 * doc/autoconf.texi (Shellology): Mention the problems with bash
13619 2.05's use of ANSI quoting in its `set' builtin.
13621 2001-10-22 Paul Eggert <eggert@twinsun.com>
13623 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13624 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13625 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13626 POSIX decided to standardize on the int flavor of strerror_r.
13627 Always do char* test, as there's no reason not to.
13628 Assign to a char* var, to catch strerror_r that returns int*.
13630 * doc/autoconf.texi (Particular Functions):
13631 Document the above changes. Also, document the fact that
13632 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13634 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13636 2001-10-20 Akim Demaille <akim@epita.fr>
13638 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
13639 the executable was missing from the log.

13643 * lib/Autom4te/General.pm (&update_file): If destination is
13644 unchanged, remove the source.
13645 (&up_to_date_p): Don't be verbose, be debug.
13646 * bin/autoreconf.in: No longer support --m4dir.
13647 (&autoreconf): Display the full path of the configure.ac we are
13648 studying.
13649 Trace it only once.
13650 Be sure to honor --force with gettextize.
13651 Always run aclocal.
13652 * doc/autoconf.texi: Adjust.
13654 2001-10-20 Akim Demaille <akim@epita.fr>
13656 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
13657 Remove, dead.
13658 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13659 `intl' is already present, as it refuses unless --force.
13660 (&parse_args): Use -I, --include instead of the old Autoconf
13661 options.
13662 ($localdir, $autoconf_dir): Remove.
13663 (@include): New.
13664 (&maybe_autoreconf): New, to preserve $_ for File::Find.
13666 2001-10-19 Jens Petersen <petersen@redhat.com>

13674 file in @configure_input@.
13675 Don't mention `automatically' in addition to `generated'.
13676 * tests/torture.at (#define header templates): Adjust.
13678 2001-10-19 Akim Demaille <akim@epita.fr>
13680 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
13681 comment, explain how to install automatic mode selection.
13682 From Russ Allbery.
13684 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
13686 * bin/autoreconf.in (autoreconf): Display the path to the
13687 configure.ac being studied.
13689 2001-10-18 Paul Eggert <eggert@twinsun.com>
13691 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
13692 long, to work around a bug in the HP C compiler version HP92453-01
13693 B.11.11.23709.GP.
13695 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
13696 (AS_BASENAME_EXPR): New macro.
13697 (AS_BASENAME_SED): Do not assume GNU sed semantics.
13698 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
13699 and fall back on 'sed' only if the other two fail. This makes
13700 AS_BASENAME act more like AS_DIRNAME.
13701 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
13702 contains white space.
13703 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
13704 Use AS_DIRNAME, since I think it's now DOS-friendly.
13705 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
13706 Allow "dirname //FOO" to return either / or //, as POSIX allows
13707 either behavior.

13711 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

13713 From Eric Sharkey.

13717 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

13812 2001-10-08 Akim Demaille <akim@epita.fr>
13814 Use `add-log-current-defun-function' for ChangeLog creation.

13836 * tests/tools.at (AT_DATA_FORBIDDEN): New.

13847 empty, and if we can find a shell that does support LINENO,
13848 then set CONFIG_SHELL to that shell and then re-execute
13849 ourselves with CONFIG_SHELL.
13851 2001-10-05 Paul Eggert <eggert@twinsun.com>
13853 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
13854 doesn't exist. Remove *.tmp, as a .tmp file is created during the
13855 build of $(TESTSUITE).
13857 2001-10-05 Akim Demaille <akim@epita.fr>
13859 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

13867 PATH_SEPARATOR before using it.
13868 Fix the absolute path case/esac pattern.
13869 Provide $0 as fallback for as_myself.
13870 Reported by Raja R Harinath.

13877 2001-10-05 Akim Demaille <akim@epita.fr>
13879 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): New, extracted from...
13880 (AS_SHELL_SANITIZE): here. Use it.
13881 (_AS_LINENO_PREPARE): Preserve the exit status of $0.lineno.
13882 From Paul Eggert.
13884 2001-10-04 Akim Demaille <akim@epita.fr>
13886 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable
13887 combination of Awk and sed to replace $LINENO.
13889 2001-10-02 Paul Eggert <eggert@twinsun.com>
13891 * doc/autoconf.texi (Limitations of Builtins): You can't use
13892 "source"; it's not portable. Remove confusing and
13893 somewhat-incorrect example involving "." and "/".
13895 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
13896 compatibility with POSIX shells.
13898 2001-10-02 Akim Demaille <akim@epita.fr>
13900 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
13901 instead of exec'ing to preserve $0 and $@.
13903 2001-10-01 Akim Demaille <akim@epita.fr>
13905 * tests/testsuite (AT_INIT) <at_pass_list>: New.
13906 Don't run twice the same test.
13908 2001-10-01 Akim Demaille <akim@epita.fr>
13910 * lib/autotest/general.m4 (AT_INIT) <--help>: Catch up with reality.
13911 No longer output the list of tests.

13915 Various small adjustments.
13917 2001-10-01 Akim Demaille <akim@epita.fr>
13919 * doc/autoconf.texi: Use @kbd for user input.

13924 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
13925 Don't use nested parenthesization. This patch was originally
13926 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
13927 but somehow it didn't get incorporated then.
13928 * doc/autoconf.texi (Limitations of Usual Tools):
13929 Clarify remark about sed and nested parenthesization.
13931 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
13932 Report an error if the size cannot be determined even though
13933 the type exists.
13934 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13935 Check for `expr' arithmetic overflow, and for compilation failure,
13936 and invoke a new argument $4 if either is discovered.
13937 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
13938 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
13940 2001-09-28 Akim Demaille <akim@epita.fr>

13946 2001-09-28 Akim Demaille <akim@epita.fr>
13948 * lib/autotest/general.m4 (AT_VICTIMS): Rename as...
13949 (AT_TESTED): this.
13950 (AT_INIT): More the wrapped section to where it will be expanded.
13951 Output `AT_tested' only when existing.
13952 Catch unexpanded PACKAGE_STRING and PACKAGE_BUGREPORT.
13954 2001-09-27 Akim Demaille <akim@epita.fr>
13956 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
13957 generates too many bug reports.
13959 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
13960 status when executing the ACTION-IF-FALSE.
13961 * tests/base.at (AC_TRY_*): Rename as...

13967 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC): Move to...
13968 * tests/c.at (Extensions, C keywords)
13969 (Broken/missing compilers, AC_PROG_CPP with warnings)
13970 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
13971 (AC_PROG_CPP requires AC_PROG_CC): here and...
13972 * tests/fortran.at (GNU Fortran 77): there.
13973 * doc/autoconf.texi (autoconf Invocation): Fix the example:
13974 AC_TRY_RUN is about compilation, not shell commands.
13975 (Test Programs): AC_TRY_RUN works as used to be advertised.
13977 2001-09-27 Akim Demaille <akim@epita.fr>
13979 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
13980 Raja R Harinath:
13981 Be sure to detect when $LINENO always returns the same value.
13982 Look for the original script, basename($0) is certainly not
13983 enough.
13984 Pass the CLI arguments to `$as_me.lineno'.
13986 2001-09-25 Akim Demaille <akim@epita.fr>
13988 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

13996 of --language now.
13998 2001-09-23 Akim Demaille <akim@epita.fr>
14000 * doc/autoconf.texi (Top): Wrap in @ifnottex.
14002 2001-09-23 Akim Demaille <akim@epita.fr>
14004 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
14005 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
14006 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
14007 builddir, buildpath, top_builddir, and top_buildpath.
14008 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
14009 the current directory.
14010 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
14011 variables *before* changing the current directory.
14012 Skip nonexistent dirs.

14014 variables.
14016 * lib/autotest/general.m4: Do not reset AT_victims.
14017 Don't compute at_srcdir nor at_top_srcdir.
14019 * tests/tools.at: Hence use top_srcdir.
14021 * tests/Makefile.am, tests/autoconf, tests/autoheader,
14022 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
14023 Remove.
14024 * tests/autoreconf.in, tests/wrappl.in, tests/autom4te.in,
14025 * tests/wrapsh.in, tests/autoupdate.in: New.
14026 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
14027 * configure.ac: Build the position independent wrappers.
14029 * man/Makefile.am: Now that test wrappers are position
14030 independent, use them and drop dark envvar magic.
14032 2001-09-23 Akim Demaille <akim@epita.fr>
14034 * doc/autoconf.texi (Common Shell Constructs): Rename as...
14035 (Programming in M4sh): this.
14036 Promote to @section.
14038 2001-09-23 Akim Demaille <akim@epita.fr>
14040 * lib/autotest/general.m4 (AT_INIT): Dump config.log last.

14052 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix shell
14053 over-escaping.

14063 (Autoconf): Adjust.
14065 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
14067 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,

14074 for $LINENO.
14076 2001-09-22 Akim Demaille <akim@epita.fr>
14078 * lib/autoconf/autotest.m4: Create `package.m4'.
14079 * tests/Makefile.am (package.m4): Remove.
14081 2001-09-22 Akim Demaille <akim@epita.fr>
14083 Rely on `$LINENO' when possible instead of `__oline__'.
14085 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
14086 `$LINENO' support replacement when not supported.
14087 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
14088 them explicitly to be sure they are not output before this section
14089 (via m4_require). Cosmetic only.
14090 * lib/autoconf/c.m4, lib/autoconf/general.m4,
14091 * lib/autoconf/programs.m4: Replace all the occurrences of
14092 `__oline__' with `$LINENO'.
14093 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
14095 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
14097 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
14098 character (u: -> ue) in a code comment.
14099 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
14100 it works.
14102 2001-09-21 Akim Demaille <akim@epita.fr>
14104 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
14105 Suggested by Jim Meyering.
14107 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14109 * lib/autoconf/programs.m4: Use extensions listed in
14110 $ac_executable_extensions when looking for programs.
14112 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14114 * lib/autoconf/general.m4: Fix a small Englisho.
14115 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
14116 setting up ac_dir_suffix and ac_top_builddir.
14117 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
14119 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14121 * doc/autoconf.texi (File System Conventions): Clarify the use of
14122 PATH_SEPARATOR.
14123 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
14124 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
14125 be used instead of ':'.
14126 * lib/autotest/general.m4: Replace occurrences of ':' in
14127 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14129 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14131 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14132 arguments. Fixed a typo.
14134 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14136 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14137 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14139 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14141 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
14142 * bin/autoupdate.in: Ditto.
14143 * bin/autoheader.in: Reworded a few comments.
14144 * bin/autoconf.in: Reworded help text for a few options.
14145 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
14146 * bin/autoscan.in, bin/autoupdate.in: Ditto.
14148 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14150 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14151 already have $file). Set output files to binary mode (helps avoid
14152 CR issues on DOSish systems).
14154 2001-09-19 Akim Demaille <akim@epita.fr>
14156 * lib/autotest/general.m4: Englishoes.
14157 From Tim Van Holder and Alexey Mahotkin.
14159 2001-09-18 Paul Eggert <eggert@twinsun.com>
14161 * doc/autoconf.texi (Common Shell Constructs): New node,
14162 documenting AS_DIRNAME.
14163 (Limitations of Usual Tools): Refer to it when discussing dirname.
14164 Also, update discussion of POSIX standard to reflect latest draft.
14166 * lib/autoconf/c.m4:
14167 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14169 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14170 Do not pass a first argument with leading '-'
14171 to expr, by parenthesizing initial integers that might be negative.
14173 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14174 now merely checks whether it is an error to pass an argument
14175 to getpgrp.
14177 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14178 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14179 whether it is a (compile-time) error to pass an argument to
14180 getpgrp. This simpler test supports the revised documentation,
14181 and is all that AC_FUNC_GETPGRP's users really need.
14183 2001-09-18 Akim Demaille <akim@epita.fr>
14185 * doc/autoconf.texi (Limitations of Make) <$<>: New.
14187 2001-09-18 Akim Demaille <akim@epita.fr>
14189 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
14190 `{}'.
14191 * lib/autotest/general.m4 (AT_INIT): Adjust.
14193 2001-09-18 Paul Wagland <paul@wagland.net>
14195 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14196 correctly.
14197 Add test for AS_BASENAME.
14198 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14199 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14200 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14201 * tests/base.at: Fixed the expected responses. The old ones were
14202 one line out...
14203 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14204 the documentation claims it should (and how it behaved in 2.13).
14206 2001-09-18 Akim Demaille <akim@epita.fr>
14208 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14209 the AC_CONFIG_COMMANDS invocation.
14210 This also solves the name clash problems.
14211 Don't set the package's ID.
14212 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14213 No longer to be shipped.
14214 (version.in): Remove.
14215 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14216 * lib/autoconf/status.m4: Adjust.
14217 Use `m4_PACKAGE_STRING'.
14218 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14219 the only optional argument is the name of the test suite.
14220 Expect `package.m4' to define the package signature.
14221 * lib/autom4te.in (Autotest): Add `package.m4?'.
14222 * tests/Makefile.am (package.m4): New.
14223 * tests/suite.at: ifnames is a victim.
14225 2001-09-18 Akim Demaille <akim@epita.fr>
14227 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14228 AC_LIBSOURCE, AC_CONFIG_FILES.
14229 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14230 program version string doesn't match the package's.
14231 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14232 after `(cached)'.
14234 2001-09-17 Paul Eggert <eggert@twinsun.com>
14236 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14237 Allow expression to return any value that can fit into unsigned long
14238 (not int, as before). Check for output errors.
14240 2001-09-17 Bruno Haible <haible@ilog.fr>
14242 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14243 Always include <stdio.h> and <stdlib.h>. Evaluate
14244 the expression in an extra function before these includes. Call
14245 fprintf "%d" only after ensuring the argument is of type 'int'.
14246 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14248 2001-09-17 Paul Eggert <eggert@twinsun.com>
14250 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14251 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14252 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14253 when they don't exist.
14255 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14256 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14257 need it.
14259 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14260 version with the version used by fileutils 4.1, except use
14261 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14262 we don't need it.
14264 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14266 2001-09-13 Akim Demaille <akim@epita.fr>
14268 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
14269 _first_.
14270 Reported by Gerrit P. Haase.
14272 2001-09-13 Akim Demaille <akim@epita.fr>
14274 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
14275 m4_defn'ing is valid.
14277 2001-09-13 Akim Demaille <akim@epita.fr>
14279 * lib/m4sugar/m4sugar.m4 (m4_append_uniq): New.
14280 * lib/autotest/general.m4 (AT_VICTIMS, AT_KEYWORDS, _AT_CLEANUP_FILE):
14281 Use it.
14283 2001-09-13 Akim Demaille <akim@epita.fr>
14285 * lib/m4sugar/m4sugar.m4 (_AS_QUOTE_IFELSE, _AS_BOX_INDIR): Use
14286 m4_match.
14287 (m4_re_escape): New.
14288 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER): Use it.
14289 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
14290 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
14291 Likewise.
14292 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
14293 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
14294 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
14295 AT_tests_all for consistency.
14296 Set at_victims.
14297 (AT_VICTIMS): Similar to AT_KEYWORDS.

14306 * lib/autotest/general.m4 (AT_INIT): Create and remove
14307 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

14421 the maintainer is dumb enough to do that...
14423 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14424 excellence in M4 quotation: consider `__file__' is active.
14426 And BTW, when invoking m4, pass the --include in the right order:
14427 the wrong one.
14429 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
14430 4m.

14457 New, extracted from main.
14458 Use IO::File wherever possible.
14459 (input.m4): Be constant, use -I instead of hard coding $tmp.
14460 Therefore be a quoted heredoc.
14461 Don't invoke `_au_disable', since ac was not loaded, but just
14462 `unm4.m4'.
14464 2001-08-31 Akim Demaille <akim@epita.fr>
14466 Version 2.52d.

14491 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
14492 (testsuite Scripts): There is no such thing as `atconfig.in'.
14493 And actually one diagram is missing: test suite runtime.
14495 2001-08-31 Akim Demaille <akim@epita.fr>
14497 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
14498 inverse order.
14500 2001-08-31 Akim Demaille <akim@epita.fr>
14502 * bin/autoupdate.in (@include): `installcheck' revealed the path
14503 to m4sugar was lacking!
14505 2001-08-31 Akim Demaille <akim@epita.fr>
14507 * man/Makefile.am (.x.1): We really have to pass
14508 autom4te_perllibdir.
14510 2001-08-31 Akim Demaille <akim@epita.fr>
14512 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

14518 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
14519 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
14520 Use directly autom4te, not autoconf.

14525 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

14545 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
14546 (autoheader): Pass --force since the test suite goes too fast for
14547 the time stamps.
14548 Adjust to the new autoheader messages.
14550 2001-08-31 Akim Demaille <akim@epita.fr>
14552 * bin/autoheader.in: Handle the acconfig.h etc. junk files.

14562 Drop AC_MACRODIR dead for real.
14563 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
14564 `autoheader: `config.hin' is created'.
14565 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
14567 2001-08-31 Akim Demaille <akim@epita.fr>
14569 * bin/autoheader.in: Rewrite in Perl.
14570 * tests/autoheader: Adjust.
14572 2001-08-31 Akim Demaille <akim@epita.fr>
14574 * bin/autoconf.in (--include, -I): New option.
14575 Map --localdir, --autoconf-dir onto it.
14576 Forward autom4te's options instead of interpreting them.
14577 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
14578 There is no such envvar since the inception of autom4te.cfg.
14579 * bin/autom4te.in (&parse_args): Uniquify `@include'.
14580 * bin/autoupdate.in: Adjust, and perform more control.

14584 2001-08-31 Akim Demaille <akim@epita.fr>
14586 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
14587 * bin/autom4te.in (&find_file): Support `FILE?' standing for
14588 optionally `FILE'.
14589 Use -e, not -f, since /dev/null for instance is OK.
14590 (&parse_args): Adjust.
14591 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
14593 2001-08-31 Akim Demaille <akim@epita.fr>
14595 * configure.ac: Also find tested executables in bin.
14596 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
14597 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
14598 installed peer executables, only PATH is allowed to resolve it.
14599 Pass `autoconf_dir' via options, not via invisible envvars.
14600 * lib/Autom4te/General.pm (&find_peer): Remove.
14601 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
14602 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
14603 * man/Makefile.am: Let help2man rely on PATH instead of trying to
14604 find the executables for it.
14605 * tests/Makefile.am: Major cleanup. Too lazy to document...
14606 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14607 We only need PERL.
14608 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14609 indeed related to running the test suite, while passing
14610 --autoconf-dir and others is related to running non installed
14611 Autoconf executables. So don't do that, leave it to...
14612 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
14613 * tests/autoscan: New.
14614 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
14615 refer to library files: rely on --language.

14619 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

14628 2001-08-29 Akim Demaille <akim@epita.fr>
14630 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
14631 Suggested by Paul Eggert.
14633 2001-08-29 Akim Demaille <akim@epita.fr>
14635 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
14636 download in a tmp dir.
14638 2001-08-29 Akim Demaille <akim@epita.fr>
14640 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

14657 2001-08-29 Akim Demaille <akim@epita.fr>
14659 * lib/autotest/general.m4: Use
14660 foo=`(command) 2>/dev/null`
14661 not
14662 foo=`command` 2>/dev/null
14663 (at-devnull): Rename as...
14664 (AT-devnull): this.
14665 (--clean): Remove AT-* files too.
14666 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.

14701 * lib/autotest/general.m4 (AT_INIT): Log the command line.

14722 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
14723 `ac_top_builddir' to mimic Automake's vocabulary, which much more
14724 readable.
14725 Adjust callers.
14726 * doc/autoconf.texi (Configuration Actions): Document the vars
14727 available in commands.
14728 Emphasize the risks of collisions in init-cmds.

15199 current $prefix to the sub-configures.
15201 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15203 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15204 extension (needed on BeOS). Reported by Guido van Rossum.
15206 2001-08-09 Akim Demaille <akim@epita.fr>
15208 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15210 2001-08-07 Akim Demaille <akim@epita.fr>
15212 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15213 removed.
15214 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15215 No need to remove the files before and after the each test, before
15216 each test and at the end of the suite is enough.
15217 Display only the children `times', not the shell's.
15218 If the test failed or was skipped, at-times is not available.
15220 2001-08-07 Akim Demaille <akim@epita.fr>
15222 Always produce testsuite.log, including when there are no
15223 failures. This helps getting information on skipped tests, and
15224 duration of the tests. Err, implement the latter btw.
15226 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15227 Dump information on the first run of each test.
15228 (AT_CLEANUP): Create `at-times' containing the duration of the
15229 test group.
15231 2001-08-07 Akim Demaille <akim@epita.fr>
15233 The use of `dumpstat' revealed that `len' was used although it
15234 should not. m4_text_wrap was using it, but in the Autoconf world
15235 where it is legal. Hence (i) test M4sh in its own world, not
15236 Autoconf's, and (ii), ahem, fix the bug :)
15238 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15239 does not like `' instead of [].
15240 (AT_INIT): Forbid `^_?AT_'.
15241 And don't output such tokens.
15242 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15243 `script.as', and `autom4te.cache'.
15244 Remove `empty' and `macro' which are no longer used.
15245 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15246 * tests/m4sugar.at: Use it.
15247 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15249 2001-08-07 Akim Demaille <akim@epita.fr>
15251 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.

15255 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15257 2001-08-04 Akim Demaille <akim@epita.fr>
15259 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15260 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15261 AC_TRY_LINK.
15262 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15263 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15264 (AC_F77_MAIN): Likewise.
15266 2001-08-04 Akim Demaille <akim@epita.fr>
15268 Don't rely on M4sugar outputting the patterns in files, since we
15269 might process the output _without_ running m4, hence without these
15270 files.
15272 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15273 * bin/autom4te.in (@Request::includes): Remove, unused.
15274 (@Request::source): Rename as...
15275 (@Request::input): this.
15276 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15277 (&handle_output): Fetch the patterns from the traces.
15278 `$forbidden' and `$allowed' are constant: use m//o.
15279 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15280 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15282 2001-08-04 Akim Demaille <akim@epita.fr>
15284 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15285 autoconf', i.e., in addition to caching traces, cache the output.
15287 * bin/autom4te.in (Request::cache): Rename as...
15288 (Request::id): this.
15289 ($cache, $icache, $tcache, $ocache): New.
15290 (&handle_m4): Save M4 output in the cache instead of $tmp.
15291 (&handle_output): Adjust.
15292 (&up_to_date_p): Check that the output cache is up to date too.
15293 (top level): Run `&handle_m4' iff force or the cache is invalid.
15294 Run `&handle_output' if the output cache is more recent.
15296 2001-08-04 Akim Demaille <akim@epita.fr>
15298 * bin/autom4te.in ($force): New.
15299 (&parse_args, &print_usage): -f, --force is a new option.
15300 (&handle_output): CPP directives might have spaces after `#'.
15301 (&parse_args): The first file only can be frozen.
15303 2001-08-04 Akim Demaille <akim@epita.fr>
15305 Don't let autom4te compute the `include' traces several times:
15306 first check that the trace cache file is up to date, and then
15307 compare its timestamp with that of the output.
15309 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15310 the preamble. Don't require 5.005 as Autom4te::General does it,
15311 and better yet (use `use', not `require'!).
15312 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15313 Class::Struct as Autom4te::Struct.
15314 * lib/Autom4te/General.pm (File::stat): Use it.
15315 (&mtime): New, export it.
15316 * bin/autom4te.in: Use it.
15317 Declare `$req' is invalid if it is outdated.
15318 Don't declare it valid before saving it if something went wrong.
15320 2001-08-04 Akim Demaille <akim@epita.fr>
15322 Autom4te shall not encode Autoconf data, and preselecting traces
15323 must be proposed to the users.
15325 * bin/autom4te.in (@required_trace): Remove.
15326 (@preselect): New.
15327 (&parse_args, &print_usage): -p, --preselect is a new option.
15328 (&up_to_date_p): Adjust.
15329 * bin/autoconf.in: Preselect some Autoconf macros.
15331 2001-08-04 Akim Demaille <akim@epita.fr>
15333 * tests/tools.at (autoconf --trace: user macros): Check traces on
15334 macros invoked without arguments, and macros invoked with multiple
15335 lines arguments.
15337 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
15339 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
15340 arguments.
15342 2001-08-03 Akim Demaille <akim@epita.fr>
15344 * bin/autoconf.in ($@): Work around the usual sh bug.
15345 From Nicolas Joly.
15347 2001-08-03 Akim Demaille <akim@epita.fr>
15349 Clean up the handling of the M4 builtins tracing exception.
15351 * bin/autom4te.in (Request::request): Don't complete M4 builtins
15352 trace requests.

15354 (@m4_builtin): this.
15355 (%m4_builtin_alternate_name): New.

15362 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,

15367 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
15368 (m4_divert_pop): Dump the whole diversion stack when a diversion
15369 mismatch happens.
15370 * bin/autom4te.in (&handle_output): Remember of the first
15371 occurrence of a possibly undefined macro, not the last.
15372 Complain about the possibly undefined macros in the same order as
15373 the appear in the output.
15374 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
15375 * tests/tools.at (autoconf: forbidden tokens, basic)

15377 autoconf's stderr, as it is now deterministic.
15378 Check that `dnl' is caught.
15380 2001-08-01 Akim Demaille <akim@epita.fr>
15382 * configure.ac: Bump to 2.52c.

15837 cross-language link tests can be performed successfully.
15838 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
15839 after $LIBS, for consistency; this should be the general rule since
