992 (autotools and whitespace in file names): Use them.
993 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
994 Cover more potentially problemtic file names. Use the new
995 functions.
997 Properly handle funny file names for headers in config.status.
998 The test suite did not cover this bug because the code was not
999 quoting properly the arguments of `rm -f' (which "fails" silently)
1000 as well as the arguments of `diff' (whose output was redirected to
1001 /dev/null so we couldn't see its error message).
1002 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
1003 file names passed to `rm' and `diff'.
1004 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1005 Add a regression test.

1101 regression in sourcing files.
1102 * tests/autotest.at (Using atlocal): New test to catch this.

1117 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
1118 detection...

1120 argument.
1121 <DEFAULTS>: Delay computation of variables based on $at_dir...

1123 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
1124 <PARSE_ARGS>: Parse new option.
1125 <HELP_TUNING>: Document it.
1126 * tests/autotest.at (Choosing where testsuite is run): New test
1127 for this feature.
1128 (Keywords and ranges): Add test for missing -k argument.
1129 * NEWS: Document this.
1130 * doc/autoconf.texi (testsuite Invocation): Likewise.

1145 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1147 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1148 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1149 mode, we change to the source directory, also set $ac_pwd so we
1150 do not go back to the build tree for the next config subdir.
1151 * tests/torture.at (Deep Package): Extend test to contain two
1152 config subdirs on the top level.
1154 Fix parallel `maintainer-check'.

1217 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1218 (m4_require): Avoid extra macro calls.
1220 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1222 * tests/torture.at (srcdir): Fix quoting.
1224 Do not pass top_srcdir to configure scripts in testsuite.
1225 * tests/autotest.at (srcdir propagation): Copy install-sh to
1226 source tree.
1227 (my only test): Drop setting of `top_srcdir'.
1228 * tests/base.at (Input/Output): Likewise.
1229 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1230 config.guess, and config.sub to test source tree.

1235 (Substitute a newline, datarootdir workaround): Likewise.
1236 (Define a newline): Adjust for linenumber changes in configure.ac.
1237 * tests/foreign.at (Libtool): Adjust comment to reflect changes.

1240 if `pwd` contains whitespace.
1242 Quote $abs_top_srcdir in tests.
1243 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
1244 * tests/tools.at (Syntax of the shell scripts): Likewise.
1246 * tests/m4sh.at (LINENO): Quote $0.
1248 Fix testsuite program wrapper for whitespace in `pwd`.
1249 The problem here is that the usual mantra is that command
1250 variables can contain arguments, thus we cannot just escape
1251 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1252 $top_builddir/tests directory early in $PATH, so that the
1253 wrappers are found by their plain name.
1254 * tests/wrapper.as: Put $testdir early in $PATH.
1255 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1257 Proper config.status --file/--header and $srcdir escaping.
1258 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
1259 characters in $ac_file_inputs.

1265 Fix Autotest for whitespace in `pwd`.

1268 Quote $at_group_dir.
1269 * tests/autotest.at (whitespace in absolute testdir): New test.
1271 * lib/autom4te.in: Quote @datadir@.
1273 Proper file name escaping in Autoconf programs and Perl modules.
1274 This includes escaping of characters special to the shell
1275 as well as special to Perl, e.g., leading `<' or `>'.
1276 For example, when $file starts with `>', `open ">$file"'
1277 wrongly tries to append to a different file.
1278 * bin/autoconf.as: Fix quoting for autom4te options.
1279 * lib/Autom4te/General.pm (shell_quote): New function, taken
1280 from coreutils, written by Jim Meyering.
1281 (mktmpdir): Use it.

1285 * bin/autoscan.in (main): Likewise.
1286 * bin/autoupdate.in (main): Likewise.
1287 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
1288 * bin/ifnames.in: Likewise, XFile usage fixes.
1289 * tests/tools.at (autom4te and whitespace in file names): Extend
1290 test. Test twice, with special characters allowed on w32, and the
1291 rest. Test leading and trailing whitespace, for `open_quote'.
1292 (autotools and whitespace in file names): New, analogous test.
1293 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1294 by Russ Allbery and Eric Blake.
1296 Sync from Automake.

1298 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1299 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1300 (update_file, contents): Use it.
1302 * Makefile.am (autom4te-update): Rewrite for git.
1304 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1306 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.

1318 When using older automake, don't downgrade build-aux/texinfo.tex.
1319 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1320 * doc/Makefile.am (TEXINFO_TEX): Add.
1322 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1324 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1325 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1326 #undef as this runs afoul of our new way of creating config.h.
1327 Problem reported by Jim Meyering in
1328 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

1332 Fix autom4te for unusual characters in input file names.
1333 * bin/autom4te.in (files_to_options): Quote active characters

1336 New test.
1338 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:

1341 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1343 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1344 `#AT_STOP_...' line at the end of each test.
1346 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1348 * lib/autotest/general.m4 (AT_INIT): For awk line number
1349 extraction script, ensure `$at_group' has a defined value
1350 even for the empty set, and properly quote its usage inside
1351 the awk script.
1353 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1355 * doc/autoconf.texi (Shell Functions): New chapter. Document
1356 IRIX sh $0 issue in functions, move content from ...
1357 (Portable Shell): ... here.
1358 (Shell Script Compiler): Note that shell functions are not
1359 totally unportable any more.

1370 Fix quoting.
1372 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1374 Fix IRIX testsuite debugging failures: $0 in functions.
1375 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1376 Do not use $0 inside a function, as IRIX sh will set that to the
1377 function name rather than the script invocation name.
1379 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1380 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1382 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1383 to extract test scripts.
1384 (AT_INIT): Extract and cache test script line numbers.
1386 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1388 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1389 subsequent fixups; the awk -> here-document conversion trashes
1390 performance too much with AIX sh.
1392 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1394 * tests/local.at: Do not test m4, perl with AT_TESTED.
1396 Diagnose and guard against write errors dealing with config.status.
1397 The general idea is this: all write failures from `configure'
1398 writing `config.status' are indicated by $ac_write_error, which
1399 is only checked at the end. This is safe because config.status
1400 code is not executed before the file is complete. Other write
1401 failures, be they inside config.status, or in sub shell/awk
1402 scripts spawned from configure or config.status, typically need
1403 earlier checking, as their results are used right afterwards.
1404 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1405 before writing config.status, check afterwards.
1406 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1407 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1408 Set `ac_write_error' for write failures to config.status. Barf
1409 upon write failures to temporary files.
1410 Adjust note about closing and reopening the here-document.
1411 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1412 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1413 reopening the here-document.
1414 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1415 Ensure `ac_write_error' does not escape into config.status.
1416 Also, add a couple of code paths not yet exercised in the test
1417 suite: a config file with input from stdin, and a config header
1418 output to stdout.
1419 Suggestion for catching write errors by Bruno Haible.
1421 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1423 Avoid error with Tru64 awk and testsuite lines with many words.
1424 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1425 reads the testsuite, set the field separator to an unusual value,
1426 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1427 even splits the input if $i, i>0, was never accessed in the script.
1429 Revert 2007-10-17 change.
1430 * TODO: Multiline args in config files and headers mean something
1431 different and are not fixed, see

1437 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1439 AC_*_TOOL does not canonicalize the prefix
1440 * doc/autoconf.texi (Generic Programs): Do not say that

1469 (AT_INIT): Pre-extract test groups into separate files.
1470 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
1471 Remove at-test-source files together with the $at_group_dir.
1472 * tests/autotest.at (Long test source lines): New test.
1474 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1477 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
1478 limitation.
1480 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
1482 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
1483 gnulib.
1485 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1487 * lib/autoconf/status.m4: Fix a couple of comment typos.
1489 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1491 2007-11-13 Jim Meyering <meyering@redhat.com>
1493 Clean up the rule to create "expr".
1494 * tests/Makefile.am (expr): Don't redirect directly to target.
1495 Redirect just once, not for each echo statement.
1496 Use $@, not literal "expr".
1498 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1500 Don't worry about preprocessor when testing long long.
1501 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1502 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1503 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1504 These no longer check for preprocessor flaws.
1505 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1506 Do not check for preprocessor flaws.
1508 2007-11-13 Jim Meyering <meyering@redhat.com>
1510 Adapt dependencies, now that a version change doesn't modify configure.ac
1511 * GNUmakefile: Remove "make clean" kludge.
1512 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1513 configure.ac.
1514 Don't redirect directly to target.
1515 Use $@, not literal "version.m4".
1517 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1519 * doc/autoconf.texi (Making testsuite Scripts): Document
1520 ":;{" shorthand as in previous patch.
1522 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1524 * doc/autoconf.texi (Limitations of Builtins): Document problem
1525 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1526 for the workaround.
1527 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1528 Use ":;{" shorthand.
1529 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1531 2007-11-12 Jim Meyering <meyering@redhat.com>
1533 Add more non-srcdir build support.
1534 * GNUmakefile (dummy): Split a long line.
1535 Add -v option to autoreconf invocation.
1537 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1538 * GNUmakefile (dummy): Remove INSTALL.
1540 Remove racy commands to build scripts in bin/ and tests/.
1541 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1542 are guaranteed to be built, remove the rules that tried to build
1543 them. Before, with a parallel build, these rules could lead to
1544 two processes writing tests/wrapper.in concurrently.
1546 Build in man/ only *after* building in bin/ and tests/.
1547 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1548 in both bin/ and tests/.
1550 Accommodate non-srcdir build-from-checkout.
1551 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1552 Use git's --git-dir=$srcdir/.git option.
1553 Add quotes, in case tarball_version_file contains shell meta-characters.
1554 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1555 * configure.ac: Pass "." to git-version-gen.
1557 Avoid spurious test failures due to version skew.
1558 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
1560 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1562 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
1563 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
1564 Remove conftest.dSYM directory.
1565 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1566 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
1567 Remove `conftest.*' recursively.
1568 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
1569 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1570 Likewise.
1571 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
1572 * THANKS: Update.

1575 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
1577 Fix typos in variable names.
1578 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
1580 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
1582 Document that $((expression)) is not portable.
1583 * doc/autoconf.texi (Shell Substitutions): Here.
1585 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1587 Ignore configure --help* errors due to LINENO-impaired shells.
1588 * tests/torture.at (Configuring subdirectories, Deep Package):
1589 In the --help* tests in read-only trees, make `.' temporarily
1590 writable again for the `stderr' file, and ignore errors due to
1591 the attempt to write configure.lineno.
1592 Report by Patrick Welche.
1594 2007-11-10 Jim Meyering <meyering@redhat.com>
1596 Generate package.m4 in build-dir, not srcdir.
1597 * tests/Makefile.am (package.m4): Adjust target.
1598 Don't redirect directly to $@.
1599 (CLEANFILES): Add package.m4.
1600 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1601 in $(srcdir).
1602 When running $(AUTOTEST), search "." before searching $(srcdir).
1604 Avoid a race condition that would make parallel "distclean" fail.
1605 * tests/Makefile.am (distclean-generic): Replace the default,
1606 automake-provided rule with an identical one, but with an additional
1607 dependency on distclean-local. Simply adding the dependency would
1608 cause automake not to emit the rule at all.
1609 * BUGS: Building with -jN works, now.
1611 Distribute git-version-gen.
1612 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1613 since GNUmakefile is distributed, and requires it for dist* rules.
1615 Remove two more generated files from version control.
1616 * INSTALL: Remove generated file.
1617 * lib/autoscan/autoscan.list: Remove generated file.
1619 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1621 * GNUmakefile (PATH): Remove stray apostrophes; they become
1622 part of PATH, which isn't wanted here.
1624 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1626 New config files output variable `top_build_prefix'.
1627 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1628 `top_build_prefix'.
1629 * doc/autoconf.texi (Preset Output Variables): Document it.
1630 * NEWS: Update.
1631 Report by Bob Friesenhahn.
1633 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1634 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1635 function, to parametrize arithmetic with expr vs. the shell.
1636 Use it where possible.
1637 Suggestion by Benoit Sigoure.
1639 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1641 Adjust the documentation of autotest WRT atlocal.
1642 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1643 when using Automake, to write a rule to produce atlocal, since it's
1644 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1645 distributed, not atconfig.in.
1647 2007-11-04 Eric Blake <ebb9@byu.net>
1649 Update list information.
1650 * README: Mention new autoconf-commit list.
1651 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.

1657 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
1659 * build-aux/.gitignore: Ignore mkinstalldirs.
1661 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
1663 2007-11-03 Jim Meyering <meyering@redhat.com>
1665 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1666 * build-aux/git-version-gen: This syncs from coreutils.
1668 Adjust the build procedure so "make check" works reliably.
1669 * README-hacking: Include an extra step between "make" and
1670 "make check" to ensure that the latter passes.
1672 Use just-built tools, when possible.
1673 * GNUmakefile (PATH): Set and export here, ...
1674 (dummy): ... rather than here.
1676 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1677 and Andreas Schwab <schwab@suse.de>
1679 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
1680 exit status bug.
1682 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1684 * configure.ac (AC_PREREQ): Require version 2.60, for
1685 AC_PROG_SED, AC_PROG_GREP.
1687 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
1688 and Jim Meyering <meyering@redhat.com>
1689 and Andreas Schwab <schwab@suse.de>
1690 and Eric Blake <ebb9@byu.net>
1692 Document a bug in GNU Bash with compound commands and redirections.
1693 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
1694 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
1695 workaround.
1697 2007-11-03 Eric Blake <ebb9@byu.net>
1699 Support m4 1.4.5 in testsuite.
1700 * tests/torture.at (Define a newline): Exclude line numbers in
1701 error message.
1702 Reported by Ralf Wildenhues.
1704 2007-11-03 Jim Meyering <meyering@redhat.com>
1706 Remove automake-provided files from version control.

1710 * build-aux/mdate-sh: Remove file.
1711 * build-aux/.gitignore: New file.
1712 Suggestion from Ralf Wildenhues.
1714 2007-11-03 Eric Blake <ebb9@byu.net>
1716 Adjust version comparison to account for git snapshot numbers.
1717 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
1718 component separator.
1719 * doc/autoconf.texi (Number processing Macros)
1720 <m4_version_compare>: Document this change.
1721 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
1723 2007-10-30 Bruno Haible <bruno@clisp.org>
1725 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
1726 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
1727 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
1728 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
1729 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
1730 Suggested by Paul Eggert.
1732 2007-10-28 Jim Meyering <meyering@redhat.com>
1734 * README-hacking: Autoconf, Automake, and Perl are required to build.
1735 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
1737 2007-10-28 Jim Meyering <meyering@redhat.com>
1739 README-hacking: Recommend running autoreconf -vi.
1740 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
1741 so that we use just-built tools when they're available.
1742 Suggestions from Ralf Wildenhues.
1744 2007-10-28 Jim Meyering <meyering@redhat.com>
1746 Make inter-release --version output more useful.
1748 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1749 which indicates that it is built using the 19th change set
1750 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1751 is a prefix of the commit SHA1.
1752 * build-aux/git-version-gen: New file.
1753 * configure.ac: Run it to set the version.
1754 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1755 * Makefile.am (dist-hook): Arrange so that .version appears only
1756 in distribution tarballs, never in a checked-out repository.
1757 * .gitignore: Add .version here, too. Just in case.
1758 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1759 not configure.ac, now that the version number changes automatically.
1761 Ensure that $(VERSION) is up to date for dist-related targets.
1762 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1763 git-version-gen doesn't match $(VERSION), but only for dist targets.
1765 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1767 Fix `Deep Package' failure with a configure script early in PATH

1797 problem reported by Bruno Haible in
1798 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
1800 2007-10-22 Eric Blake <ebb9@byu.net>
1802 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
1803 preprocessor.
1805 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
1807 Don't check for bug in HP-UX 11.00 cpp.
1808 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
1809 Use -1ull rather than -1u, since that causes problems with gnulib; see
1810 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
1812 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1828 escaping of backslash in here-documents.
1830 Fix `Deep Package' test failure on FreeBSD.

1832 unnecessarily. Do not try running `/bin/sh configure' with a
1833 configure script to be found in $PATH, if the shell does not do
1834 this resolution. Fixes test failure on FreeBSD.
1836 Fix config header generation with AIX awk.
1837 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
1838 script, use helper array D_is_set, as `" 0"' does not evaluate

1876 * lib/autotest/general.m4 (BANNERS): New named diversion.
1877 (TESTS_END): Diversion no longer used.
1878 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a

1880 array of banner text from a special diversion.
1881 <PARSE_ARGS_END>: No longer need awk to find banners.
1882 <TESTS>: Banners are no longer processed by main driver loop, so
1883 we no longer need case statement.
1884 (AT_BANNER): Rewrite to populate new diversion.
1885 (AT_SETUP): Each test invokes its own banner. No output is needed
1886 to the TESTS diversion.
1887 * doc/autoconf.texi (Writing Testsuites): Document slight
1888 semantics change.

1933 columns.
1934 (TEST_FUNCTIONS): Based on recent changes, rename...
1935 (TEST_GROUPS): ...to this.
1937 Reject FreeBSD m4.

2886 2007-06-03 Noah Misch <noah@cs.caltech.edu>,
2887 Bruno Haible <bruno@clisp.org>
2889 * lib/autoconf/c.m4 (AC_OPENMP): Use a simple loop instead of compiler

2912 2007-05-21 Paul Eggert <eggert@cs.ucla.edu>
2914 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp
2915 choice, since that's what we do with --enable-largefile etc.
2916 Redo indenting and assignments to simplify things a bit, and make
2917 the parens work with Emacs.
2919 * doc/autoconf.texi (Generic Compiler Characteristics): Fix typo
2920 in my previous change: AC_C_OPENMP -> AC_OPENMP. Reported by Bruno

2998 section titles and other comments; no code change.
3000 2007-05-01 Kevin Ryde <user42@zip.com.au>
3002 * doc/autoconf.texi (Particular Programs): Typo
3003 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
3005 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
3007 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
3008 'configure' will fail if the shell lacks proper support for shell
3009 functions. Suggested by RMS.
3011 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
3013 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
3014 about Solaris /bin/printf '%010000x' 123. Problem reported by
3015 Bruno Haible.
3017 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
3019 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
3020 for a.* when searching for executables, as this prevents users
3021 from having files like a.c. Problem reported by Ralf Wildenhues in:
3022 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
3023 This fixes a problem introduced on 2000-12-19.

3033 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
3034 AC_CHECK_TYPE, AC_CHECK_TYPES.
3035 * doc/autoconf.texi (Generic types): C types must be type-names
3036 (the C terminology), not type-ids (the C++ term). C++ types
3037 must not be anonymous.
3038 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
3039 for C++; this drops support for anonymous struct and union types,
3040 which were problematic anyway.
3041 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
3042 for C++.
3044 2007-04-12 Jim Meyering <jim@meyering.net>

3057 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
3058 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
3059 with objects too. Document the restrictions on its use.
3060 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3061 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3062 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3063 works but the latter doesn't, then it's a valid type.
3064 This lets people use function types and so forth.
3065 For C++ there doesn't seem to be a simple solution, so leave it alone.
3066 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3067 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3068 AC_CHECK_TYPE; that wasn't documented or necessary.
3070 2007-04-11 Stepan Kasal <kasal@ucw.cz>
3072 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

3115 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
3116 checks for unsigned long long int.
3118 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
3120 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
3121 nonstandard grep R.E. escape sequences.
3123 2007-03-17 Jim Meyering <jim@meyering.net>
3125 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
3126 (Limitations of Usual Tools): Also list \< and \>, and mention that
3127 HP-UX's grep, like the one from Solaris, does not support that syntax.
3129 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3131 * doc/autoconf.texi (Specifying Names): `--host' does not
3132 change the build type.
3134 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
3136 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN

3147 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
3148 universal binaries. Problem reported by Elias Pipping.
3150 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
3152 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.

3170 status of rm so we know when it failed.
3171 If cleaning of test dir failed before running the test, warn.
3172 Output the line separator in verbose mode before the warning
3173 to make clear the warning belongs to the following test.
3175 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>

3190 carriage return.
3191 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
3192 with traditional Awk and begin.
3193 * tests/torture.at (Limitations of Builtins): Document the problem

3198 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
3200 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
3201 input from /dev/null in awk test, so even Solaris /usr/bin/awk
3202 will not wait for input with a script containing only a BEGIN
3203 rule.
3205 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>

3227 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
3229 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
3230 latest version.
3231 (Shell Substitutions): Note problems with @{var:=value} etc.
3232 Add a new section for problems with @{#var} etc. Problem noted

3236 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3238 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3239 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3240 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3241 substitution will still be done by the special code.
3242 Report by Jim Meyering.
3244 * doc/autoconf.texi (File System Conventions): Mention that
3245 $PATH_SEPARATOR is for the build system only.

3263 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3265 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3266 early on the reader side, drop stderr of the input to avoid
3267 `broken pipe' error output; this may happen even with shell
3268 builtin `echo' of some bash versions. Reports by Ian Macdonald
3269 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3271 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3283 Fix some wording problems noted by Paolo Bonzini in:
3284 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3285 * doc/autoconf.texi (Signed Overflow Examples): Give more
3286 discussion about the allow_superuser_privileges example,
3287 and change it a bit to make things clearer.
3288 (Optimization and Wraparound): Clarify whether the compiler
3289 will generate an infinite loop for the example derived from
3290 Autoconf's mktime test.
3291 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3292 Also, clarify unsigned multiplication overflow.
3294 2007-01-04 Eric Blake <ebb9@byu.net>
3296 * bin/Makefile.am (RELEASE_YEAR): New macro.
3297 (edit): Use it to supply correct copyright year to scripts.
3298 * bin/autoconf.as (version): Use it.
3299 * bin/autoheader.in ($version): Likewise.
3300 * bin/autom4te.in ($version): Likewise.
3301 * bin/autoreconf.in ($version): Likewise.
3302 * bin/autoscan.in ($version): Likewise.
3303 * bin/autoupdate.in ($version): Likewise.
3304 * bin/ifnames.in ($version): Likewise.
3306 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3308 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3309 feedback. The most important changes document what happens when
3310 you convert an out-of-range value to a signed integer type, and
3311 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3312 a + b.
3314 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3315 rewrite, taking notions from the recent discussion on the gcc and
3316 autoconf mailing lists; please see
3317 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3318 and follow the many links.
3319 (Integer Overflow Basics, Signed Overflow Examples):
3320 (Optimization and Wraparound, Signed Overflow Advice):
3321 (Signed Integer Division): New sections.
3323 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3325 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3326 preprocessor macro arguments in traced name.
3327 * doc/autoconf.texi (Defining symbols): Document longstanding
3328 support for AC_DEFINE-ing macros with arguments, and document
3329 behavior when the same variable has multiple AC_DEFINEs.
3330 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3331 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3332 macros directly, giving much shorter and simpler code.
3334 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3336 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3337 space before "$ac_configure_args" to prevent a 'config.status
3338 --recheck' failure if ac_configure_args doesn't contain a leading
3339 space. This works around a problem with the XEmacs configure.ac,
3340 which uses the (undocumented) ac_configure_args variable
3341 inconsistently with Autoconf.
3343 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3345 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3346 Include <limits.h>, and use its INT_MAX to rewrite the
3347 j loop so that it does not overflow 'int'. Problem reported by
3348 Ralf Wildenhues in
3349 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3350 Play it safe by shifting left by 1 rather than multiplying by 2,
3351 as GCC is less likely to optimize this away when the value
3352 is signed (when it assumes overflow leads to undefined behavior).
3353 Also, don't assume time_t uses two's complement.
3355 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3357 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3358 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3359 dumps core on it. Report by Tim Rice.
3361 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3363 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3364 --disable-option-checking to --help output even when
3365 AC_PRESERVE_HELP_ORDER is not used.
3366 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3367 --with argument, rather than argument with [-.] replaced by
3368 underscores.
3369 * NEWS: Fix typo in previous change; the news was in the
3370 wrong section.
3372 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3374 * NEWS: Warnings are now generated by default for unknown
3375 --enable-* and --with-* options.
3376 * doc/autoconf.texi (Option Checking): Renamed from
3377 (Configure Option Checking). Tighten up the wording a bit.
3378 (External Software, Package Options): Cross-reference to Option
3379 Checking, and use this to shorten our section.
3380 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3381 "$x" to test "x$foo" != x.
3382 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3383 Don't warn if $enable_option_checking is "no".
3384 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3385 ac_unrecognized_opts to the empty string.
3386 Don't echo the unrecognized opts, as this might mishandle
3387 backslashes or leading -.
3388 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3389 usage next to the other --disable-FEATURE options in the
3390 help string.
3392 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3394 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3395 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3396 Print warning for unrecognized --with and --enable options
3397 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3398 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3399 Disable option checking when subdirs are configured.
3400 (AC_OUTPUT): If warnings are enabled, print warning about
3401 unrecognized --with and --enable options at the end of
3402 the configure output (as well as at the beginning).
3403 * doc/autoconf.texi (Option Checking): New node.
3404 Document new option warning functionality.
3406 2006-12-16 Eric Blake <ebb9@byu.net>
3408 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3409 * NEWS: Start news for current version.
3411 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3413 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3414 Define HAVE_GETMNTENT to 1, not to the empty string.
3415 Problem originally reported by Jochen Friedrich in
3416 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3418 This change prompted by a problem report by Andrey Simonenko in
3419 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3420 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3421 object-like macros only, in the traditional portable character
3422 set.
3423 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3424 Warn about attempts to define things that are not identifiers.
3425 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3426 awful hack that AC_DEFINEd macro names containing parentheses.
3428 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3430 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3431 too drastic, even if Texinfo in theory requires it for info mode.
3433 (config.status Invocation): Renamed back from Recreating a
3434 Configuration).
3435 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3436 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3438 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3440 * NEWS: Version 2.61a.
3442 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3443 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3445 * NEWS: Document changes with echo and printf, and the lack
3446 of limits on the total size of multi-line values of substituted
3447 variables, and the AC_FUNC_FSEEKO fix.
3449 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3451 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3452 Writing configure.ac.
3453 (Autoconf Input Layout): Renamed from configure.ac Layout.
3454 (Recreating a Configuration): Renamed from config.status Invocation.
3455 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3456 (acconfig Header): Renamed from acconfig.h.
3457 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3458 (Writing Testsuites): Renamed from Writing testsuite.at.
3459 (Autom4te Cache): Renamed from autom4te.cache.
3461 * BUGS: Remove mention of VPATH problem, since it's now documented
3462 not to be a bug in the Autoconf build procedure itself, but rather
3463 a problem with the proprietary `make' programs.
3465 * doc/autoconf.texi (Build Directories): Add a cross reference
3466 to VPATH and Make.
3468 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3469 * doc/standards.texi: Sync from gnulib.
3471 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3472 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3473 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3474 generated automatically.
3476 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3478 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3479 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3480 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3482 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3484 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3485 `CEOF$ac_eof' special marker, the awk script cannot contain a
3486 line matching `^CEOF', so this is not needed any more.
3487 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3488 special marker in the test.
3490 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3492 * tests/tools.at (autom4te preselections): Use `find -newer';
3493 remove one of the sleeps.
3495 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3496 more readable, using ...
3497 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3499 * doc/autoconf.texi (autoheader Invocation): Do not double-
3500 quote the parameter of `AH_BOTTOM' in the example.
3502 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3504 * doc/autoconf.texi (Configuration Headers): Remove the
3505 example with multiple input files.
3506 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3507 multiple input files.
3509 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3511 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3512 creating the awk substitution script, handle one input line at a
3513 time, so that the maximum length of a substituted (multi-line)
3514 value is not limited by the size of the sed pattern space.
3515 The trade-off is a slightly repetitive sed script.
3516 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3517 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3518 * tests/torture.at (Substitute a 2000-byte string): Increase the
3519 test with several long lines, they should not be caught by sed
3520 limits any more.
3522 * tests/tools.at (autom4te preselections): New test, to flag
3523 entries missing from autom4te.cfg.
3524 Report by David Byron <dbyron@hheld.com>.
3526 * tests/torture.at (Substitute a 2000-byte string): Actually use
3527 AC_PROG_AWK, so the last change works as intended.
3528 (Substitute and define special characters): Likewise.
3529 (Substitute a newline): Likewise.
3531 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3532 instead of `awk' consistently.
3533 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3534 * tests/torture.at (Torturing config.status): Test both the
3535 result of AC_PROG_AWK and plain awk.
3536 (Substitute a 2000-byte string): Likewise.
3537 (Substitute and define special characters): Likewise.
3538 (Substitute a newline): Likewise.
3540 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3542 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3543 can be assigned to a function pointer. Problem reported by
3544 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3545 part of a patch by Ralf Wildenhues in that same bug report.
3547 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3549 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3550 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3552 2006-12-01 Eric Blake <ebb9@byu.net>
3554 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3555 cross-compiling from cygwin to mingw.
3556 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3557 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3558 to lib/autoconf/c.m4.
3560 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3562 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3563 string for more reliable failure. Wrap the entire test that
3564 causes the broken Solaris printf to dump core, in a subshell,
3565 so the segmentation fault message is reliably suppressed.
3566 Fix shell expansion errors by using /usr/ucb/echo always;
3567 avoid an error on systems without it by another subshell.
3568 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3569 subshell-$as_echo to `as_echo', for better error message.
3571 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3573 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3574 `BASH_SOURCE' contain a newline, set them to empty, as they may
3575 not be unset.
3577 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3579 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3580 years and is too hard to maintain now. The last straw was
3581 reported by Jerker Baeck in
3582 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3583 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3584 * doc/autoconf.texi (Particular Functions): Move
3585 AC_FUNC_SETVBUF_REVERSED from here...
3586 (Obsolete Macros): ... to here. Say that it does nothing now.
3587 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3588 Turn into (almost) a no-op.
3590 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3591 (AC_C_VOLATILE):
3592 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3593 These macros are obsolescent and new applications shouldn't need them.
3594 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3595 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
3596 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
3597 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3598 (AC_FUNC_VPRINTF): Likewise.
3599 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3600 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3601 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3603 * doc/autoconf.texi (Setting Output Variables): Mention that
3604 @VAR1@VAR2 has unspecified behavior. Problem reported by
3605 Ralf Wildenhues.
3606 * NEWS: Mention this.
3608 * Makefile.am: Put only a single '#' into the copyright notice,
3609 so that it's also present in the output file. Standardize wording
3610 in makefile copyright notices to match GNU coding standards.
3611 * bin/Makefile.am: Likewise.
3612 * doc/Makefile.am: Likewise.
3613 * lib/Makefile.am: Likewise.
3614 * lib/freeze.mk: Likewise.
3615 * lib/autoconf/Makefile.am: Likewise.
3616 * lib/autoscan/Makefile.am: Likewise.
3617 * lib/autotest/Makefile.am: Likewise.
3618 * lib/m4sugar/Makefile.am: Likewise.
3619 * man/Makefile.am: Likewise.
3620 * tests/Makefile.am: Likewise.
3621 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
3622 one-line file.
3624 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3626 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3627 in the sed script that mangles the awk script: delete up to the
3628 first exclamation mark only.
3629 * tests/torture.at (Substitute and define special characters):
3630 Test '!' too.
3632 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3634 Rewrite config files generation: avoid quadratic growth in
3635 the number of substituted variables by using awk instead of sed
3636 for the bulk of the substitutions.
3637 * NEWS: Mention this.
3638 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3639 forbidden in the output (and thus input) file.
3640 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3641 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3642 generate just one large awk script for substitutions,
3643 eliminating much of the earlier complexity, while adding some
3644 new complexity. Only expand the substitution templates at
3645 configure time, for smaller configure script size. If
3646 _AC_SUBST_FILES are used, test 'awk' for working getline support
3647 at config.status time. If absent, interpolate through the
3648 shell. The awk script was written with much help
3649 from Paolo Bonzini and Paul Eggert.
3650 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3651 (_AC_SED_FRAG_NUM): Likewise.
3652 (_AC_SUBST_CMDS): Renamed from...
3653 (_AC_SED_CMDS): ...this.
3654 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3655 * tests/torture.at (Substitute a 2000-byte string): Also
3656 substitute a line with 1000 words, and a variable with several
3657 long lines.
3658 (Substitute and define special characters): Test awk special
3659 characters, and put substitution input strings `@foo@' in the
3660 output, to test that no recursion happens; test several other
3661 combinations from Paolo Bonzini.
3663 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3665 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3666 that replaced echo with AS_ECHO where this wasn't necessary.
3667 Problem reportd by Ralf Wildenhues.
3668 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3669 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3670 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3672 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3674 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3676 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3678 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3679 that traditional Awk lacks 3-arg "split". It has it.
3680 Mention that FS must be a single character, and a few other
3681 99-byte limits of traditional Awk.
3682 Mention that if (i in a) doesn't work with traditional Awk.
3684 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3686 * tests/autotest.at (BSx641-newline in command):
3687 (BS-BS-newline in command, BSx640-newline in command):
3688 (Newline-CODE-BS-newline in command):
3689 (Single-quote-BS-newline in command):
3690 (Single-quote-newline-BS-newline in command):
3691 Use printf '%s\n' instead of echo, for portability to hosts
3692 where echo interprets backslashes. This will break on hosts
3693 that lack printf, but for now let's assume all such hosts
3694 are dead (if not, we should get reports of test failures).
3696 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3698 'echo' has some portability problems, when given a first argument
3699 with a leading '-', or when given any argument containing '\'.
3700 Avoid using 'echo' in these cases.
3701 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
3702 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
3703 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3704 * lib/autotest/general.m4 (AT_INIT): Likewise.
3705 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
3706 argument might be unportable.

3708 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.

3712 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):

3725 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3726 * bin/autoconf.as: Redo verbose flag implementation, as the old
3727 scheme wouldn't work with AS_ECHO.
3728 * lib/autotest/general.m4 (AT_INIT): Likewise.
3729 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3730 Don't use ECHO_T, since ECHO_N is now reliable.
3731 * lib/autotest/general.m4 (AT_INIT): Likewise.
3732 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3733 rather than using a here-document to put the script into a file.
3734 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
3735 use AS_ECHO.
3736 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3737 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3738 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3739 bug, but we might as well stop using ECHO_N and ECHO_C internally.
3740 * lib/autotest/general.m4 (AT_SETUP): Likewise.
3741 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
3742 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3743 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
3744 operand, as AS_ECHO requires. Avoid double file name expansion.
3745 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3746 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3747 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3748 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3749 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3750 Double-quote strings that would otherwise contain M4 comments.
3751 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3753 * configure.ac (AC_INIT): Bump to 2.61a.
3754 * NEWS: Likewise.
3756 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3758 Version 2.61.
3760 * configure.ac (AC_INIT): Bump to 2.61.
3761 * NEWS: Likewise.
3763 * tests/autotest.at (Macro with backslash in a test title):
3764 Comment out for now, as this tests neither fails nor passes
3765 reliably. Problem reported by Ralf Wildenhues.
3767 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3769 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
3770 in previous change, which caused test failures.
3772 2006-11-16 Stepan Kasal <kasal@ucw.cz>
3774 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
3775 code for --enable, --disable, --with, and --without to...
3776 (_AC_INIT_PARSE_ENABLE): ... a new macro.
3777 * doc/autoconf.texi (Package Options):
3778 * NEWS: Document that AC_ARG_ENABLE allows dots, too.

3847 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3848 and Joel E. Denny <jdenny@ces.clemson.edu>

3857 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set

3859 Imported from a similar patch to gnulib by Bruno Haible.
3861 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3863 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
3864 * doc/autoconf.texi (C Compiler): Document them.
3865 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
3866 New macros, taken from gnulib.
3868 2006-11-07 Paul Eggert <eggert@cs.ucla.edu>

3879 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
3880 and Stepan Kasal <kasal@ucw.cz>

3887 argument. Extend to check titles printed by ./micro-suite and
3888 ./micro-suite -l and the title in micro-suite.log.
3889 (Backquote in a test title,
3890 Single-quote in a test title,
3891 Double-quote in a test title): Don't expect failure anymore.
3892 (Backslash in a test title): Put a non-whitespace character after the
3893 backslash so that Bourne shells might actually see it as an escape
3894 sequence.
3895 (Brackets in a test title,
3896 Pound in a test title,
3897 Comma in a test title,
3898 Quoted Macro in a test title,
3899 Macro in a test title,

3902 Macro with double-quote in a test title,
3903 Macro with backslash in a test title): New tests expected to fail.
3904 * tests/torture.at (#define header templates): M4-quote this title in
3905 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
3906 The visible effect was a stray [] in the testsuite output.
3908 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3910 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
3911 `trap ... 0' inside a function, for AIX sh.
3913 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3915 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3916 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3917 5363) simply issues a warning when dividing by zero at compile
3918 time. Problem reported by Elias Pipping.
3920 2006-10-26 Eric Blake <ebb9@byu.net>
3922 * THANKS: Update.
3923 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3924 show effect on macros that expand with commas.
3925 Reported by Joel E. Denny.
3927 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
3928 Also work with M4 1.4.8.

3942 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm

3949 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
3951 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3952 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3953 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3954 reported by Nelson H. F. Beebe for Coreutils 6.4.
3956 * tests/tools.at (autoconf --trace: user macros): Remove test
3957 for tracing multiline macros, since m4 1.4.7a uses a different
3958 way to number lines. Problem reported by Ralf Wildenhues.
3960 2006-10-24 Stepan Kasal <kasal@ucw.cz>
3962 * bin/autom4te.in (handle_m4): Do not redirect stdin to
3963 /dev/null since the heuristics for interactive behaviour was
3964 fixed in CVS m4.
3966 * bin/autom4te.in: With --force, always refresh the output
3967 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
3969 * bin/autoconf.as: Fix the verbose message at the end.
3971 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

3988 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
3989 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
3991 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3993 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
3995 2006-10-19 Eric Blake <ebb9@byu.net>
3997 * lib/m4sugar/m4sugar.m4 (m4_mkstemp): New macro.

3999 * lib/emacs/autoconf-mode.el (autoconf-font-lock-keywords): Color
4000 m4_mkstemp.
4001 * doc/autoconf.texi (Redefined M4 Macros): Document m4_mkstemp.

4017 2006-10-14 Stepan Kasal <kasal@ucw.cz>
4019 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
4020 looking for special shell characters.
4021 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4022 macro defined by AS_VAR_PUSHDEF before passing it as a
4023 parameter.
4024 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
4025 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

4034 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4036 (Imported from Automake.)
4037 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4038 which incorrectly sets the mode of an existing destination
4039 directory. In some cases the unpatched install-sh could do the
4040 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4041 system. We hope this is rare in practice, but it's clearly worth
4042 fixing. Problem reported by Alex Unleashed in
4043 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4044 Also, don't bother to check for -m bugs unless we're using -m;
4045 suggested by Stepan Kasal.
4047 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4049 Import this change from Automake:

4053 is enabled by default with gnu and gnits strictness.
4054 Report from Bruno Haible.
4056 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
4057 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
4058 gnu and gnits modes.
4060 Import this change from Config:
4062 2006-09-20 Ben Elliston <bje@gnu.org>
4063 * build-aux/config.sub (score, score-*): New.
4065 Import this change from Gnulib:
4067 2006-09-16 Karl Berry <karl@gnu.org>
4068 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4069 to avoid sectioning errors.
4071 Import these changes from Texinfo:
4073 2006-10-04 Karl Berry <karl@gnu.org>
4074 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
4075 (\quoteexpand): rename to \rquoteexpand.
4076 (\codequoteleft): new def, to look for @set codequotebacktick.

4078 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
4079 (\code): must use new \...Char values, since now ` is active.
4081 2006-08-26 Karl Berry <karl@gnu.org>
4082 * build-aux/texinfo.tex (\textdegree): New command.
4084 2006-08-12 Karl Berry <karl@gnu.org>
4085 * build-aux/texinfo.tex (error \box0): smaller font.
4087 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4089 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
4091 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4093 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4094 added to the template can get mangled.
4096 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4098 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4099 include the default headers, and redefine obstack_chunk_alloc
4100 and obstack_chunk_free. Fixes false failure with glibc.
4102 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4104 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
4105 for backward compatibility with Libtool 1.5.22. Problem reported
4106 by Ralf Wildenhues.
4108 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4110 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
4111 AC_PROG_CC.

4114 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4116 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
4117 the NonStop platform.
4118 * doc/autoconf.texi (Posix Variants): Likewise.
4119 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4121 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4122 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4123 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4124 Use a better substitute, by inspecting the output of "ls"
4125 rather than just using ":".
4126 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4127 rather than AS_EXECUTABLE_P, since we needn't worry about
4128 non-regular files here.
4130 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4131 due to configuration hassles with this. See Tonya Underwood's report
4132 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
4133 * doc/autoconf.texi (Special Shell Variables): Likewise.
4135 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4136 Stepan Kasal <kasal@ucw.cz>

4141 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4143 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4144 initialization which is not inherited through the environment
4145 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4146 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4148 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4150 * doc/autoconf.texi (Limitations of Usual Tools): Describe
4151 problems with mkdir -p -m.
4153 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4155 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4156 comment about ac_cpp_err; it was incorrect, and anyway
4157 ac_cpp_err is being removed below.
4158 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4159 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4160 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4161 nobody uses it.
4162 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4163 with werror_flag and conftest.err and so forth. This is more
4164 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4165 and anyway the user shouldn't normally want to see this gorp logged.
4166 Problem reported by Ralf Wildenhues.
4167 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4168 empty, not 'no', since the rest of the code uses 'test -z'.
4170 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4172 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4173 Use a single call to AC_DO_TOKENS rather than multiple, for
4174 efficiency.
4175 (_AC_LINK_IFELSE): Test that resulting file is executable.
4176 Problem reported by mwoehlke in
4177 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4179 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4180 than creating a file to use with test -x; this is much faster.
4182 2006-10-02 Bruno Haible <bruno@clisp.org>
4184 * lib/autom4te.in (Automake-preselections): Add
4185 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4187 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4189 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4190 standard error, `experr' should be used, not `expout'.
4192 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4194 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4195 fseeko testing program twice; just use the earlier result.
4196 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4197 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4198 still doesn't let the program compile.
4199 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4200 failed.
4202 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4203 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4204 include it, without including anything else.
4205 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4206 expressions.
4207 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
4209 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4211 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4212 `error.h', and include it, for a `error_at_line' prototype.
4213 Use a nonempty format string in the link test.
4214 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4215 for a declaration of wait3.
4217 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4219 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
4220 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
4221 can apply to constants too, and that it checks for macro defns.
4222 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
4223 and simply cast the identifier to void. This handles structure
4224 values. Problem reported by Ralf Wildenhues.
4225 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
4227 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4234 * tests/semantics.at (AC_CHECK_MEMBERS): Also test with a struct
4235 member.

4246 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): Avoid `gcc -Wall'
4247 warnings (uninitialized value).
4248 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
4249 present.
4250 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add

4324 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
4325 works with GNU M4 1.4.3 again; make the normalized form
4326 match the current m4 message; fix the description.

4335 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
4336 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
4337 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
4338 assume C89.

4360 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
4361 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
4362 accept files with extension `.f'. For consistency, also prefer
4363 xlf over f77.
4364 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug

4436 deal with LEXLIB.
4437 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
4438 didn't work if some values were cached but not others. Test for
4439 broken lex libraries like native ia64-hp-hpux11.22; see
4440 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
4441 work around the problem by preferring an empty LEXLIB to -lfl or
4442 -ll. Let the user set LEXLIB='' to indicate no library needed.
4444 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
4445 * README: Likewise.
4446 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

4643 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.

4692 * doc/autoconf.texi (Volatile Objects): New section.
4694 * NEWS: Document previous change.
4696 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4698 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4699 Require that long long int be at least 64 bits wide. C99 requires
4700 this and enough programs depend on it so we should check for it.
4701 Bruno Haible reports in
4702 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4703 that long long int is 32 bits wide with some nonstandard compilers.
4704 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
4706 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
4708 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4709 to a nonexistent file, so that we don't have to worry about
4710 a local site configuration that doesn't use /usr/local.
4711 Problem reported by Keith Marshall in
4712 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4714 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4716 * doc/autoconf.texi: Be more consistent about using @acronym with
4717 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4718 quite right (it talked about "OSF/Tru64", even though the
4719 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4720 and it even mentioned "OSF 4"!) and at this point there's little
4721 reason to talk about OSF any more, since it died in 1994.
4722 (Specific Compiler Characteristics): Simplify example of
4723 negative-size array.
4724 (File Descriptors): Reorder to make the text flow better.
4725 Remove joke about "appreciate the various levels"; I didn't get it.
4726 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4727 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4728 (File Descriptors, Limitations of Usual Tools):
4729 Tone down the advice against renaming or removing open files.
4730 (Limitations of Usual Tools): Add a new section, on 'rm'.
4732 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4734 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4735 -lXt in LIBS, idea from Karsten Hopp; this was due since
4736 this change:
4738 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4739 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4740 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4741 (which belong to Xt, not X itself). See Debian bug 327655.
4743 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4745 * configure.ac (AC_INIT): Bump to 2.60a.
4746 * NEWS: Update.
4748 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4750 Version 2.60.
4752 * configure.ac, NEWS: Update.
4754 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4756 * config/texinfo.tex: Sync from upstream.
4758 * bin/autom4te.in (handle_traces): Transform the `@S|@'
4759 quadrigraph correctly in traces.
4761 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
4762 Fix typos.
4764 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
4765 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4766 not defined.
4767 * doc/autoconf.texi (Changed Directory Variables): New node,
4768 to document the whole `datarootdir' business a bit better.
4769 * NEWS: Update.
4770 * tests/torture.at (datarootdir workaround): Extend test.
4771 Prompted by report by Alexandre Julliard.
4773 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4775 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4776 when using default mode of IBM C 6 for AIX. Problem and two-line
4777 fix reported by Larry Jones.
4779 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4781 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4782 about literal '${datarootdir}' if a definition is found in the
4783 output file.
4785 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4787 * NEWS: Use "M4" rather than "m4" when appropriate.
4788 Problem reported by Eric Blake.
4789 * doc/autoconf.texi: Likewise.
4790 Use @acronym around BSD, GCC, and GNU when appropriate.
4791 (Why GNU M4): Renamed from "Why GNU m4".
4792 (Redefined M4 Macros): Mention that Posix
4793 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4794 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4795 to int.
4797 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4799 * bin/autom4te.in (handle_output): Do not forbid the empty
4800 pattern.
4801 * tests/tools.at (autoconf: the empty token): New test.
4803 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4805 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4806 calls, so that we do not care whether they are LIFO or FIFO;
4807 in the m4_wrap, do not check which diversion is the topmost
4808 one, just check that the stack is balanced at the end.
4809 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4810 base diversion forever--pop the previous diversion before
4811 opening the new one; consequently, remove the m4_wrap call.
4812 * lib/autotest/general.m4 (AT_INIT): Likewise.
4813 * tests/m4sugar.at: Do not use
4814 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
4816 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
4817 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4819 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4820 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4821 Rework example of m4wrap token-pasting trouble so that it doesn't
4822 care whether it's LIFO or FIFO.
4823 Fix some "contrary to"s that are awkward in English.
4825 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4827 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4828 to `yes' instead of `int$1_t' if the type is found, for more
4829 consistent configure output (where $1 is the number of bits).
4830 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4831 Suggested by Bruno Haible.
4833 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4834 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4835 with system headers. Report by Bruno Haible.
4837 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4839 * config/config.guess, config/config.sub: Sync from upstream.
4841 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4842 in order to avoid picking up an older installed frozen m4sh.m4f.
4843 Besides an outdated shell startup, this could have been created
4844 by an earlier M4 version with incompatible frozen file format.
4846 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4848 * README: Recommend m4 1.4.4 instead of 1.4.3..
4849 * doc/autoconf.texi: Likewise.
4850 (Special Chars in Names): Say that $(.FOO) is portable, as
4851 suggested by Stepan Kasal.
4852 (Installation Directory Variables, Build Directories):
4853 (Automatic Remaking, Subdirectories, Fortran Compiler):
4854 (Making testsuite Scripts, Defining Directories):
4855 Quote variable usages better.
4856 (Making testsuite Scripts): Add clean-local rule to makefile
4857 snippet, by Eric Blake.
4858 (Installation Directory Variables): Fix table item font.
4859 Reword slightly to clarify. Generalize advice about
4860 not using special characters to include all file-related
4861 vars, not just VPATH.
4862 (Special Chars in Variables): Warn about special characters in
4863 $(srcdir) too.
4864 (Assignments): Clarify default-value example as suggested by
4865 Ralf Wildenhues in
4866 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4867 (Special Shell Variables): Note leading ./ or ../, as suggested
4868 by Eric Blake.
4869 (Limitations of Builtins): Under cd, warn about CDPATH.
4870 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4871 Ralf Wildenhues.
4873 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4875 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4876 `@var', for texi2html.
4877 (Systemology): Some more word wrapping, for DVI output.
4878 (autom4te Invocation): The short option for `--melt' is `-M',
4879 not `-m'.
4881 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4883 * doc/autoconf.texi: More formatting and English tweaks,
4884 many suggested by Ralf Wildenhues.
4885 Reword to avoid "@code{...}'s" and the like, since it's ugly
4886 with Emacs info mode. discontents -> woes.
4887 Put a few "will"s back. time stamp -> timestamp.
4888 side-effect -> side effect.
4890 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4892 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4893 Warn about $@ not persisting. Problem reported by Julien Danjou in
4894 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4895 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4896 Mention other special chars, too.
4898 2006-06-14 Eric Blake <ebb9@byu.net>
4900 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4902 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4904 * doc/autoconf.texi: Some systematic minor improvements, as
4905 follows. Use "makefile" when talking about makefiles
4906 generally (which might be named "makefile" or "Makefile" or even
4907 "foo.mk"), "Makefile" when talking about a specific makefile
4908 called "Makefile". This unclutters the text from weird quotes
4909 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4910 values" rather than "@var{foo}s" and similar constructs containing
4911 "}s". Use "Make rules" rather than "Makefile rules". Minor
4912 English-language improvements. Change the prefix "sub-" to "sub"
4913 and "re-" to "re".
4914 Put blank lines around examples more consistently.
4915 Avoid "rather" and "very" as intensifiers.
4916 Avoid "will" as an auxiliary.
4917 (Limitations of Make): Split this node into....
4918 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4919 (Leading _ in Macro Names, Backslash-Newline-Newline):
4920 (Backslash-Newline Comments, Long Lines in Makefiles):
4921 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4922 (obj/ and Make, make -k Status, VPATH and Make):
4923 (VPATH and Double-colon, $< in Explicit Rules):
4924 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4925 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4926 New nodes, resulting from splitup of Limitations of Make.
4927 All cross-references changed. Raise the top node from
4928 a section to a chapter, and all subnodes accordingly.
4929 Redo the introductory wording to match the new organization.
4930 (Installation Directory Variables): Use an example that is
4931 closer to what Autoconf actually does. Mention that VPATH's
4932 value should not contain metacharacters or white space.
4933 (Fortran Compiler): Fix a VPATH bug in an example.
4934 (Leading _ in Macro Names): Mention that this problem is no longer
4935 of practical concern.
4936 (VPATH and Make): Reword the advice to make it clearer
4937 that Autoconf and Automake support VPATH in non-GNU make, but
4938 many packages have bugs in this area.
4939 ($< in Explicit Rules): Refer to Build Directories rather
4940 than using a (non-VPATH-safe) example.
4941 (Automatic Rule Rewriting): Mention the sort of disaster that
4942 can ensue with Solaris-style rule rewriting with VPATH.
4944 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4946 * doc/install.texi (Compilers and Options): Weaken the
4947 suggestion to use GNU make for VPATH builds.
4949 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4950 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4952 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4953 in regular expression.
4955 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4957 * doc/autoconf.texi (Installation Directory Variables):
4958 Drop extra @samp from `@table @samp' item.
4959 (Limitations of Usual Tools): Comment fix.
4960 Do not nest @samp just to point to other table items.
4961 (Writing testsuite.at) <AT_CHECK>: The second argument to
4962 `@dvar' is already @samp'ed.
4963 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4964 do not use @var in the second argument.
4966 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4968 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4969 $as_shell.exe too. Problem reported by Andreas Buening in
4970 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
4972 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4974 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4975 `unused variable' compiler warning, for `-Wall -Werror'.
4976 Reported by Jaap Haitsma in
4977 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4979 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
4981 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4982 case the compiler dumps core. Problem reported for
4983 OpenServer 5.0.7 by Tim Rice in
4984 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
4985 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4986 Likewise.
4988 2006-06-06 Tim Rice <tim@multitalents.net>.
4990 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
4991 "ERROR" only shows up in "make check" output if there is an
4992 error.
4994 2006-06-06 Eric Blake <ebb9@byu.net>
4996 * tests/tools.at (automatically allowed tokens): Fix typo.
4998 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5000 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5002 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5003 typically overflows on x86 CPUs, even though the C standard
5004 requires otherwise.
5006 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5008 * configure.ac (AC_INIT): Bump to 2.59e.
5009 * NEWS: Update.
5011 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5013 Version 2.59d.
5015 * config/texinfo.tex: Sync from upstream.
5017 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5018 seen, invoke libtoolize with `--ltdl' argument.
5019 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5020 * NEWS: Update.
5021 Suggested by Eric Blake.
5023 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5025 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5026 reported by Ralf Wildenhues.
5027 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
5029 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5033 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5035 * doc/autoconf.texi: Modernize some of the references to Solaris.
5037 2006-06-05 Stepan Kasal <kasal@ucw.cz>
5039 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5040 message issued by AC_REQUIRE.
5041 * tests/m4sugar.at: Check m4_require's error message.
5042 * tests/base.at: Check AC_REQUIRE's error message.
5043 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5044 to...
5045 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5046 AT_CHECK_M4.
5047 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5048 `expout' as the last parameter.
5049 * tests/tools.at: Adapt to the above change.
5051 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5053 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5054 information about race-free implementations of mkdir.
5056 2006-06-04 Eric Blake <ebb9@byu.net>
5058 * bin/autoreconf.in (help): Document M4 environment variable.
5059 * bin/autoconf.as (Usage): Likewise.
5060 * bin/autom4te.in (help): Likewise.
5061 * doc/autoconf.texi (autom4te Invocation): Likewise.
5063 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5065 * NEWS: GNU make now recommended for VPATH builds.
5066 Mention that some macros are now documented to be obsolescent.
5067 * doc/autoconf.texi:
5068 Prefer "current" to "modern" to describe
5069 currently-used (albeit perhaps old-fashioned) hosts.
5070 Mention which ancient features no longer need to be worried about.
5071 setgid -> set-group-ID
5072 setuid -> set-user-ID (these are the Posix terms)
5073 Fix some misuses of "only".
5074 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5075 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5076 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
5077 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
5078 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
5079 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
5080 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
5081 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
5082 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
5083 Mention that these macros are obsolescent.
5084 (Installation Directory Variables): shall -> should
5085 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5086 Mention that it's now safe to use 3 and 4.
5087 (Limitations of Usual Tools): cp -r is now specified by Posix.
5088 Omit longwinded and obsolescent discussion of cp -f.
5089 Modernize discussion of expr, ls.
5090 (Limitations of Make): Modernize discussion of VPATH builds.
5091 Mention $? as a workaround in some cases.
5092 * doc/install.texi (Basic Installation):
5093 Mention "./configure; make; make install" first. Be more
5094 specific about why this file is generic. Remove unnecessary
5095 parens. Remove misleading "only". Remove obsolete advice
5096 about csh. Don't say "configure" takes awhile; say it
5097 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5098 and CC=c99 rather than CC=c89, as these are blessed by current
5099 Posix. Recommend GNU make if doing a VPATH build.
5101 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5103 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5104 examples involving shell prompts.
5106 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5107 and Paul Eggert <eggert@cs.ucla.edu>
5109 * doc/autoconf.texi (Here-Documents): Add details about the
5110 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5111 use "here-documents" instead of "here documents".
5113 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5115 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5117 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5119 * doc/autoconf.texi (File System Conventions): Warn about ":"
5120 anywhere in directory names.
5122 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5124 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5125 about quoting the case statement, just in case.
5126 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5127 was fixed in ksh93g; reported by Ralf Wildenhues.
5129 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5131 * doc/autoconf.texi (System Services): Do not document
5132 overriding EXEEXT via ac_cv_exeext=ext.
5133 (Particular Programs) <AC_PROG_MKDIR_P>:
5134 Document that ${MKDIR_P} understands --.
5135 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5136 comment.
5138 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5140 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5141 argument with leading hyphen. Problem reported by Paul Eggert.
5143 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5145 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5146 about quoting ac_try: quote all of it, if any of it seems suspicious.
5147 This means we don't have to worry about ${ or sed any more.
5148 Also, double-quote the case statement, to work around misuses via
5149 underquoting as reported by Ralf Wildenhues in
5150 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5151 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5152 undocumented and dangerous macro.
5153 Problem reported by Ralf Wildenhues in
5154 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5156 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5158 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5159 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5160 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5162 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5164 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5165 since evidently some packages rely on the old, broken behavior.
5166 Problem reported by Ralf Wildenhues in
5167 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5168 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5169 pre-2006-05-26 definitions, but leave in the comments that
5170 these macros are dangerous and should not be used.
5171 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5172 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5173 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5174 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5175 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5177 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5179 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5180 the use of 'tr', since this is our only use of 'tr'.
5182 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5183 and Paul Eggert <eggert@cs.ucla.edu>
5185 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5186 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5188 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5190 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5191 the output file in the `${datarootdir}' test.
5193 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5194 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5196 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5197 mention of `datarootdir' in the input file(s), but literal
5198 `${datarootdir}' in the output file, and we haven't warned yet,
5199 then warn as well: the user may have (erroneously) used
5200 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5201 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5202 * tests/torture.at (datarootdir workaround): Extend this test.
5203 * NEWS: Update.
5205 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5206 and Paul Eggert <eggert@cs.ucla.edu>
5208 * doc/autoconf.texi (autoheader Invocation): The first argument to
5209 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5210 alternatives and clear up the language a bit.
5212 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5214 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5215 ac_config_guess, ac_config_sub, ac_configure.
5216 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5217 Fix typo that prevented an unnecessary space from being removed.
5218 Problems reported by Ralf Wildenhues in:
5219 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5221 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5223 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5224 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5225 Don't use the term "thread-safe" to talk about mkdir race
5226 conditions, since the problem is more a process than a thread
5227 issue. Problem reported by Stepan Kasal in:
5228 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5229 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5230 the test for 'install' more closely. Look at MKDIR_P first.
5231 Look in the PATH, and at /opt/sfw/bin.
5232 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5233 Don't bother to try mkdir -p, since we already check mkdir --version;
5234 just look at the version number. (There's no easy way to check
5235 for race-free implementations.)
5236 * tests/tools.at (autoconf: subdirectories): Adjust to above
5237 changes, since MKDIR_P now might end in "/mkdir -p".
5239 * doc/autoconf.texi (autoheader Invocation): Mention that the
5240 first arg of AC_DEFINE_UNQUOTED must be a literal.
5241 Problem reported by Ben Pfaff in
5242 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5244 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5245 * doc/autoconf.texi (Special Chars in Variables): New section.
5246 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5247 (Installation Directory Variables): Quote $(datadir) better.
5248 (Limitations of Builtins): Describe some of eval's trickiness.
5250 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5251 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5252 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5253 in front of every arg, not just trailing args. Quote apostrophes.
5254 (_AC_EVAL_ECHO): New macro.
5255 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5256 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5257 removed.
5258 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5259 exposed by quoting of eval argument. Put the command on line line
5260 so it logs better.
5261 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5262 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5263 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5264 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5265 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5266 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5267 Use eval more safely.
5268 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5269 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5270 to be replaced.
5271 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5272 lines, exposed by quoting of eval argument.
5274 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5275 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5277 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5278 initialization of `ac_cv_exeext', do not override it if it was
5279 already set, unless it was set to `no', for compatibility with
5280 Autoconf-2.13, and comment this.
5281 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5282 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5283 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5284 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5285 Document that this test may be overridden by setting
5286 `ac_cv_exeext'.
5288 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5290 Revert these two patches:
5292 2006-04-06 Eric Blake <ebb9@byu.net>
5293 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5294 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5295 2006-04-01.
5297 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5298 Clean up _AC_COMPILER_EXEEXT* macros.
5299 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5300 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5301 ac_file to the name of the default output file and call
5302 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5303 initial `rm' of the candidate files...
5304 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5305 the same list in subsequent `rm' calls, and for the temporary
5306 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5307 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5308 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5309 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5310 no longer needed) by libtool. Make it a cache check.
5311 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5312 copied here by mistake.
5313 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5314 _AC_COMPILER_EXEEXT.
5315 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5316 _AC_COMPILER_OBJEXT directly.
5317 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5319 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5321 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5322 Fix description of how the buggy `sed' works.
5324 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5326 Sync from Automake:
5328 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5329 ENOLCK. Only mention `make -j' when applicable. Only raise
5330 fatal errors when `make -j' is involved. Improve error message.
5332 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5334 * doc/autoconf.texi (Here-Documents): We now know more about
5335 the variable expansion in here documents bug.
5336 Thanks to Tim Rice and Stepan Kasal.
5338 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5339 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5341 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5343 * tests/autotest.at (Multiline command from M4 expansion):
5344 No failure to be expected if the shell quotes newlines in
5345 commands in the `set -x' output. Report by Tim Rice.
5346 * THANKS: Update.
5348 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5350 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5351 expansion in the here-documents used by config.status, as that
5352 runs afoul of the Korn shell version M-12/28/93d bug described in
5353 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5354 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5355 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5357 2006-05-23 Jim Meyering <jim@meyering.net>
5359 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5360 Fix typo introduced with 2006-04-02 change. It reversed the sense
5361 of the test.
5363 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5365 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5366 ac_dB slightly, to save bytes in the script.
5367 Max out at 50 lines, rather than 96; this is more likely
5368 (though not guaranteed) to avoid obscure 'sed' failures.
5370 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5372 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5373 `tr -d -' as bad option argument. Work around this by deleting
5374 an unrelated character.
5375 Report by Tim Rice <tim@multitalents.net>.
5377 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5378 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5379 Stepan Kasal <kasal@ucw.cz>
5381 * doc/autoconf.texi (Particular Programs): Do not promise that
5382 we always prefer the GNU version of the program, and that we
5383 search according to PATH; both rules can have exceptions.
5384 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5385 AC_PROG_SED. Move descriptions of limitations
5386 to the Limitations of Usual Tools section.
5387 (Limitations of Usual Tools) <sed>: Mention script length
5388 limitations with Solaris /usr/ucb/sed.
5389 <grep>: Fix wording for empty alternative. Mention that -c and
5390 -l should not be combined, and that -E and -F should not be
5391 combined.
5393 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5394 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5396 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5397 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5399 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5401 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5402 AC_DEFINE is now passed to m4_pattern_allow.
5403 * NEWS: Mention that; likewise for AC_SUBST.
5404 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5405 the parameter to m4_pattern_allow.
5406 * tests/tools.at: Add a check for that.
5408 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5410 * lib/autoconf/status.m4: Fix typos.
5412 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5414 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5415 only the files that this macro generates.
5417 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5419 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5420 the HP-UX sed limitation of 99 commands, labels do not count.
5421 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5422 in the comment.
5423 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5425 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5427 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5428 Import the following fix from coreutils:
5430 2006-01-13 Jim Meyering <jim@meyering.net>
5432 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5433 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5434 not double-quote uses of that variable, to accommodate the rare
5435 case in which getmntent is available in none of the libraries
5436 checked. This happens at least on FreeBSD 5.0.
5438 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5440 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5441 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5442 some other programs unwisely rely on these undocumented vars.
5443 But put in warning comments about them.
5444 Problem reported by Ralf Wildenhues in
5445 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5446 * NEWS: Document that these variables are intended to go away.
5448 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5450 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5451 and set the language to C++ (analogous to the equivalent Fortran
5452 tests).
5454 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5455 * doc/autoconf.texi (C++ Compiler): Document it.
5456 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5457 * NEWS: Update.
5459 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5461 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5462 that caused config.status to generate 100-command sed scripts; the
5463 portable limit is 99.
5465 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5467 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5468 variable `ac_d' instead of `d' to avoid infringing namespace.
5469 Report by Ralf Menzel.
5471 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5473 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5474 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5475 * tests/tools.at (autoconf: subdirectories): New test, taken from
5476 the corresponding problem report by Ralf Wildenhues in:
5477 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5479 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5480 Quote some uses of shell variables if they might suffer unexpected
5481 globbing. This doesn't fix all instances of quoting problems that
5482 I found, just the easy ones that look safe.
5483 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5484 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5485 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5486 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5487 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5488 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5489 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5490 Likewise.
5491 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5492 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5494 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5496 * bin/autoreconf.in ($help): Reword according to the manual.
5497 Suggested by Olly Betts.
5499 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5500 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5502 * bin/autoreconf.in: Pass the directory argument to
5503 `require_configure_ac'. Fix comment.
5504 * tests/torture.at (Configuring subdirectories): Expose this.
5505 Reported by Olly Betts.
5507 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5509 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5510 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5511 Automake as follows:
5513 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5514 `$configure_in' instead of `configure.in', to preserve
5515 directory component.
5517 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5519 * config/config.guess, config/config.sub, config/texinfo.tex,
5520 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5522 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5524 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5525 test for C99 conformance; (bool) 0.5 is an integer constant
5526 expression, but (bool) -0.5 is not. Problem reported by Fedor
5527 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5529 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5531 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5532 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5533 Warn about obsolete install-sh files. Remove stray sentence
5534 fragment and fix cross reference.
5535 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5536 install -d; this undoes the 2006-05-10 change.
5537 (MKDIR_P): Mark with AN_MAKEVAR.
5538 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5539 that we don't require $INSTALL to be thread-safe. Move comments
5540 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5541 of AC_PROG_INSTALL. Output a message saying that we're checking
5542 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5543 MKDIR_P instead of AC_SUBST.
5544 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5545 Special magic for MKDIR_P, too.
5546 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5547 a dnl.
5548 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5550 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5552 Sync from Automake, as follows:
5554 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5555 * config/install-sh: Initialize IFS, so field splitting isn't
5556 turned off later.
5557 * config/mkinstalldirs: Likewise.
5558 * config/missing: Remove superfluous quotes. Replace all uses of
5559 `[' by `test', for consistency, and for..
5560 * config/missing (sed_minuso, sed_output): New variables.
5561 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5562 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5563 Fixes `missing' to detect `--output' for help2man. Fixes

5565 (autom4te): Document in `missing --help'.
5567 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5569 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5570 * config/install-sh: Don't use 'path' to talk about file names,
5571 as per GNU coding standards. Close a race condition reported by Ralf
5572 Wildenhues and Stepan Kasal. There is still a race condition
5573 on hosts that predate Posix 1003.1-1992, but we can't help this.
5574 Don't mishandle weird characters like space on pre-Posix hosts.
5575 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5576 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5577 AC_PROG_MKDIR_P from AS_MKDIR_P.
5578 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5579 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5580 earlier editions are not (including Automake 1.8.3).
5581 Do not suggest mkinstalldirs for thread-safety.
5582 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5583 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5584 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5585 presence of special characters and race conditions.
5586 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5587 in Autoconf's name space.
5589 2006-05-10 Bruno Haible <bruno@clisp.org>
5590 and Paul Eggert <eggert@cs.ucla.edu>
5592 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5593 from Automake with minor changes.
5594 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5596 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5598 * config/install-sh: Update to Automake CVS version, as follows:
5599 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5600 * lib/install-sh: Simplify the expr implementation of dirname.
5601 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5602 * lib/install-sh: Handle --, and diagnose unknown options.
5604 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5606 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5607 `./autom4te' to create `./testsuite', since the `all' target
5608 will ensure its presence, but `installcheck' should not create
5609 the uninstalled wrappers.
5611 * tests/torture.at (Unusual Automake input files): Skip if we
5612 detect automake < 1.8.
5614 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5616 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5617 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5618 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5619 * NEWS: Update.
5621 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5623 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5624 munge (multiple) white space and other oddities.
5625 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5626 single quotes in variable assignment.
5627 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5628 and similar failures by adding multiple spaces, tabs, and other
5629 special characters.
5630 Report and different test suggested by Francesco Romani
5631 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5633 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5634 single quotes, we only need to search for single quotes; this
5635 both simplifies the search pattern, and makes us less
5636 susceptible to `echo' variations for arguments not containing
5637 single quotes.
5638 (_AC_ARG_VAR_VALIDATE): Likewise.
5640 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5642 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5643 `$*' and IFS concatenation issue with traditional shells and
5644 bash-2.04. Report by Seanster@Seanster.com.
5646 2006-05-03 Bruno Haible <bruno@clisp.org>
5648 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5649 precisely which Mac OS X versions have the od problem.
5651 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5653 * doc/autoconf.texi: Use @option systematically.
5655 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5656 and Bruno Haible <bruno@clisp.org>
5658 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5659 about 'od'.
5660 (Integer Overflow): Mention the special case of integer division
5661 overflow.
5663 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5665 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5666 traditional shells like the Solaris one that do not use the
5667 first IFS character for assembling `$*'.
5668 Prompted by a related report from autoconf_bug@nro.ca.
5670 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5671 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5673 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5674 Mention more problems with the -e option.
5676 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5678 * NEWS: Typo.
5679 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5681 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5682 in URLs to improve DVI formatted output (requires texinfo 4.6).
5683 (System Services, Systemology, Shellology): Likewise.
5684 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5685 output.
5687 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5688 continuous text.
5689 (Runtime): Fix macro argument names to match description:
5690 `action-if-found' -> `action-if-true' and similarly.
5691 (Obsolete Macros): Likewise.
5692 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5693 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5694 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5696 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5698 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5700 * ChangeLog: Typo.
5701 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
5702 DVI output.
5704 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5706 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
5707 /bin/sh set unsorted output.
5708 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
5709 * tests/local.at: Likewise.
5711 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
5713 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
5714 (Integer Overflow, Null Pointers, Buffer Overruns):
5715 (Floating Point Portability, Exiting Portably): New sections.
5716 (Writing Test Programs): Fix some langauge. Recommend exiting
5717 with status 1, not merely nonzero. Clarify exit declaration.
5718 (Run Time): Move C exit status stuff to new Exiting Portably section.
5719 (Systemology): Mention Posix and levenez. Update v7 reference.
5720 (Portable Shell): Mention the Posix shell.
5722 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5724 * bin/autoconf.as (me): Replace by as_me.
5726 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5728 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5729 since as_me isn't set yet.
5731 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5733 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5734 a few minor bugs in this area.
5736 * doc/autoconf.texi (Programming in M4sh): Comment out the
5737 documentation of AS_BASENAME, for now.
5738 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5739 (Limitations of Builtins) <basename>: Do not refer to
5740 AS_BASENAME.
5741 * bin/autoconf.as (me): Don't use AS_BASENAME.
5742 (dir): Remove the unused variable.
5743 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5744 AS_DETECT_REQUIRED. All uses changed.
5745 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
5746 All uses changed.
5747 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
5748 (AS_BASENAME): Use "basename --" to protect against leading "-".
5749 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
5750 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
5751 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
5752 (_AS_DIRNAME_PREPARE): Likewise.
5753 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
5754 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
5755 (AS_DIRNAME): Use "dirname --".
5757 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5759 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5760 of "run time" and "run-time" changed to "runtime", for consistency.
5761 * lib/autoconf/fortran.m4: Likewise (in comment).
5762 * lib/autoconf/functions.m4: Likewise.
5763 * lib/autoconf/general.m4: Likewise.
5764 * lib/autoconf/headers.m4: Likewise.
5766 * doc/autoconf.texi (Run Time): Document the exit status situation
5767 with more accuracy and detail.
5769 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5771 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5772 Archive is not officially `GNU' any more. Update URL.
5773 (Defining Directories): Likewise
5774 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5776 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5778 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5779 newline from the `trap' code to finish `config.log'; the NetBSD
5780 /bin/sh resets the exit status after an empty command, as
5781 documented in doc/autoconf.texi.
5782 Reported by Dalibor Topic <robilad@kaffe.org>.
5784 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5786 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5787 Suggested by Bruno Haible.
5789 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5791 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5792 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5793 Instead, just list the shells that we know work.
5794 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5795 changed. Be more cautious about the _cv_ variable.
5796 * tests/tools.at (Syntax of the shell scripts): Check the
5797 _cv_ variable once, at first, to avoid an internal autoconf error
5798 when sh -n does not work.
5800 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5802 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5804 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5806 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5807 use ">&-" since we're only 99.999% sure that this is portable,
5808 and since the MinGW bug is fixed in a different way.
5809 * lib/autotest/general.m4 (AT_INIT): Likewise.
5811 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5813 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5814 before opening config.log, to avoid hitting a bug on MinGW.
5816 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5818 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5819 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5820 This works around a MinGW bug reported by Eric Paire.
5821 Make sure that all writes to the log file append to it,
5822 rather than possibly losing data.
5823 * lib/autotest/general.m4 (AT_INIT): Likewise.
5825 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5827 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5828 description.
5830 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5832 * NEWS: Update.
5834 * configure.ac (AC_INIT): Bump to 2.59d.
5836 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5838 Version 2.59c.
5840 * Makefile.maint (news-date-check): Do not require a leading `*'
5841 before the release date in NEWS.
5843 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5844 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5846 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5847 the instantiated file do not contain the string 'datarootdir'
5848 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5849 @mandir@, replace the reference '${datarootdir}' by the value.
5850 * tests/torture.at (datarootdir workaround): New test.
5851 * NEWS: Advertise this temporary fixup.
5852 Based on a patch by Bruno Haible, reported and analyzed by
5853 Paul Eggert and Noah Misch.
5855 2006-04-12 Eric Blake <ebb9@byu.net>
5857 * tests/autotest.at (Debugging a failed test): Fix comment.
5859 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5861 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5862 all the changes since 2006-04-07.
5864 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5866 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5867 succeeded, but `ln -s file dir' failed, take care to remove the
5868 leftover target before the next test, to prevent its spurious
5869 failure; also make sure `ln file dir' works before selecting it.
5870 Thanks to Keith Marshall for pointing this out.
5871 * THANKS: Update.
5873 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5874 assignments in `at_debug_args', so that we put them correctly
5875 in the `run' script.
5876 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5877 Reported by Eric Blake.
5879 2006-04-11 Eric Blake <ebb9@byu.net>
5881 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5882 top-level tests after micro-suite has been run. Used in...
5883 (Debugging a successful test, Debugging script and environment),
5884 (Debugging a failed test): ...these new tests. The first of these
5885 is fixed by...
5886 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5887 macro, split out from...
5888 (AT_INIT): ...here, so that using -d also generates a run script.
5889 Document that -d inhibits top-level logging.
5890 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5891 inhibits top-level logging; debug scripts are created.
5893 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5894 check.
5895 * tests/autotest.at (Empty test, Empty check): New test to check it.
5897 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5898 from gcc.
5900 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5902 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5903 the files if a problem appears. Make the empty *.at files
5904 read-only, too. Proposed by Ralf Wildenhues.
5906 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5908 * config/Makefile.am: Add comment to force updated Makefile.in.
5910 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5911 space only patch to this file, this patch causes the Makefile.in
5912 files that include freeze.mk to be updated, and thus have a
5913 newer time stamp again, which in turn makes a pristine CVS
5914 checkout have correct time stamps.
5916 * Makefile.maint (cvs-sv): New macro, to be used..
5917 (config.guess-url_prefix, config.sub-url_prefix)
5918 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5919 point to CVS text checkout of Gnulib files.
5920 (copyright-check): Bump current year.
5921 (announcement): Do not hard-wire `./announce-gen'.
5922 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5923 correctly.
5924 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5925 `chmod +x'.
5926 (wget_files): Update config.guess, config.sub, texinfo.tex by
5927 `wget-update', now that their URLs work again.
5929 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5931 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5932 Problem noted by Paul D. Smith.
5934 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5936 * doc/autoconf.texi: Remove unused words from word list.
5937 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5938 .x-sc_trailing_space: New files.
5940 * doc/standards.texi: Sync from gnulib.
5942 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5943 `LIBOBJDIR' as experimental.
5945 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5946 with a target directory; it's internally implemented as `cp'
5947 anyway, but since Autoconf advertises the possibility to use
5948 a target directory when LN_S is `ln -s', we need to find out.
5949 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5950 analyzed by Keith Marshall <keith.marshall@total.com>.
5952 * THANKS: Update.
5954 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5956 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5957 confdefs.h as-is. In general, if it has backslash-newline or the
5958 like, then it doesn't work either to sort or to remove empty
5959 lines.
5961 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5963 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
5965 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
5967 * lib/autom4te.in (Automake-preselections): Preselect
5968 _AM_SUBST_NOTMAKE.
5970 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5972 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5973 apostrophe within a single-quoted string, as this is the usual
5974 tradition and is easier to read than '"'"'. Don't rely on the
5975 shell treating "$/" like '$/'. Use a more-consistent indenting
5976 style for the trap.
5978 2006-04-09 Eric Blake <ebb9@byu.net>
5980 * tests/autotest.at (Backquote command substitution),
5981 (Multiline backquote command substitution): Remove mistaken
5982 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
5983 applied...
5984 (Parenthetical command substitution, Multiline parenthetical
5985 command substitution): here.
5987 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5989 Import macros from gnulib (often changing their name).
5991 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
5992 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
5993 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
5994 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,
5995 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T,
5996 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
5997 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
5998 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
5999 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
6000 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
6001 The manual mentions Gnulib more prominently.
6002 * doc/autoconf.texi (Gnulib): New node.
6003 (Pointers): Add Gnulib URL.
6004 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
6005 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
6006 Gnulib section.
6007 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
6008 suggest a #define rather than a typedef for _Bool, and mention
6009 Gnulib rather than trying to substitute stdbool code.
6010 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
6011 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
6012 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
6013 AC_STRUCT_DIRENT_D_TYPE.
6014 (Particular Types): Mention stdint.h and inttypes.h as standard
6015 headers too.
6016 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
6017 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,

6062 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6064 Revert the patch from 2006-04-01 and only improve
6065 _AS_DETECT_BETTER_SHELL:
6067 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6068 skip nonexistent directories.
6069 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6070 only shell candidates which exist.
6071 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6072 * lib/autotest/general.m4 (AT_INIT): No need to give three
6073 parameters to _AS_PATH_WALK.
6075 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
6076 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6078 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6079 distinguish m4sugar macros.
6080 * tests/tools.at (autoupdating with aclocal and m4_include):
6081 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6082 test case by Noah Misch <noah@cs.caltech.edu>.
6084 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6086 Revert my change from 2006-03-17, in other words:
6087 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
6088 and DUALCASE=1.
6089 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
6090 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
6091 it is set.
6093 2006-04-07 Eric Blake <ebb9@byu.net>
6095 * doc/autoconf.texi (Programming in M4sh): Document that
6096 AS_MKDIR_P exits the script on failure.
6097 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6099 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6101 * config/elisp-comp, config/install-sh, config/mdate-sh,
6102 config/missing, config/mkinstalldirs: Sync from Automake.
6104 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
6105 from Automake.
6107 * doc/make-stds.texi: Sync from gnulib.
6109 2006-04-06 Eric Blake <ebb9@byu.net>
6111 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6112 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced

6118 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6120 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6121 whether `set' quotes correctly: redirect stderr of the tested
6122 `set', and use a subshell, for Ultrix; use `sed' instead of
6123 `grep' for zsh `set' which may write binary output; match only
6124 at the beginning of a line, to avoid false positives.
6125 In order to avoid false positives by unrelated variables with
6126 multiline content, put the dump algorithm in a subshell and
6127 unset all variables containing newlines (except some which are
6128 special to the shell). Warn about cache variables that are
6129 unset.
6131 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6133 * config/config.guess, config/config.sub, config/texinfo.tex:

6142 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
6143 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
6144 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
6145 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
6147 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
6148 shell issue with double-quoted command substitutions of native
6149 commands.

6170 * tests/Makefile.am (maintainer-check-posix):
6171 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
6173 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
6174 ac_config_<foo>s again, sometimes normalized, sometimes not.
6175 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6176 (AC_CONFIG_COMMANDS): Do not do so here.
6177 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6178 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6179 2005-07-25 rewrite. Noticed by Noah Misch.
6181 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6182 _AC_PRESERVE_HELP_ORDER, ...
6183 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
6185 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
6186 inside m4_expand_once; it is redundant.
6188 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
6189 for --help from Cygnus `configure.'
6191 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

6201 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
6202 Noah Misch <noah@cs.caltech.edu>
6204 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
6205 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
6206 * doc/autoconf.texi (Help Formatting): New node.
6207 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
6209 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6211 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
6212 lib/autoconf/specific.m4, lib/autoconf/status.m4,
6213 lib/autoconf/types.m4, lib/autotest/general.m4,
6214 tests/mktests.sh, tests/torture.at: White space cleanup:

6217 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
6219 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
6221 2006-04-05 Eric Blake <ebb9@byu.net>
6223 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
6224 empty test suite works.
6225 * tests/autotest.at (Empty test suite): Remove xfail.
6227 2006-04-05 Noah Misch <noah@cs.caltech.edu>

6230 TAGS to ac_config_<foo>s.
6231 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
6232 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
6233 normalizing it, consistent it with previous releases.
6234 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
6236 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
6238 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
6239 Use simplified args that Eric Blake originally suggested.
6241 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
6243 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6244 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
6245 Use 'comm' rather than N instances of grep; this also fixes a bug
6246 whereby substrings were incorrectly matched, causing us to not
6247 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
6248 (exclude_list): Exclude empty macros.
6249 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
6251 Use awk rather than grep -E or egrep, to avoid

6254 Switch from grep to awk syntax.
6255 (ac_exclude_script): Renamed from ac_exclude_egrep.
6256 (au_exclude_script): Renamed from au_exclude_egrep.
6258 2006-04-04 Noah Misch <noah@cs.caltech.edu>
6260 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
6261 a subdirectory subject to Cygnus `configure'.
6262 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
6264 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
6265 report request when we have no AC_PACKAGE_BUGREPORT.
6267 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6269 * THANKS: Update.

6272 generated files.
6274 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
6275 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
6276 typedef'ed restricted pointer, to catch a compiler bug on
6277 HP-UX 11.x, and fix warnings so it passes with -Werror.
6278 (_AC_PROG_CC_C99): Likewise.
6279 Reported by Albert Chin <china@thewrittenword.com>.
6280 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.

6295 * THANKS: Add myself.
6297 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6299 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
6300 to log, point to testsuite output tree.
6302 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
6304 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
6305 * doc/autoconf.texi (Function Portability): Mention that C++

6309 Remove; all uses removed.
6310 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

6330 Clean up _AC_COMPILER_EXEEXT* macros.
6332 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6333 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6334 ac_file to the name of the default output file and call
6335 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6336 initial `rm' of the candidate files...
6337 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6338 the same list in subsequent `rm' calls, and for the temporary
6339 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6340 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6341 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6342 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6343 no longer needed) by libtool. Make it a cache check.
6344 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6345 copied here by mistake.
6346 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6347 _AC_COMPILER_EXEEXT.
6348 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
6349 _AC_COMPILER_OBJEXT directly.

6381 Autoconf version number despite a zero- or one-argument AC_INIT.
6383 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
6384 subordinate tools.
6385 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
6386 * doc/autoconf.texi (autoreconf Invocation): Document it.
6388 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
6389 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.

6395 rm failed to remove it.
6397 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6399 * bin/autoupdate.in: Redefine m4_location so that warnings print
6400 the correct lines of the input file by subtracting..
6401 (_au__first_line): ..this new definition.
6403 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
6404 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
6405 Remove stray newline in output.
6406 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
6407 AC_DEFUN this for autoconf, including the obsoletion diagnose.
6408 Fixes autoupdating of code where the replacement output contains
6409 m4sugar macros.
6410 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
6411 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

6413 * tests/tools.at: Several new tests for all of this.
6414 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
6415 hairy details.
6416 The AC_LANG_SAVE issue was reported against Libtool by
6417 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
6418 Kristian Kvilekval <kris@cs.ucsb.edu>.
6420 2006-04-01 Stepan Kasal <kasal@ucw.cz>
6422 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
6423 switch all of them on and of when necessary. Fixes the bug when
6424 m4sugar macros (e.g., m4_define) were expanded after the first
6425 automatic update (e.g., after AC_PREREQ or AC_INIT).
6427 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

6974 (Coding Style): y is like s with respect to / and ,.
6975 (Limitations of Usual Tools): Document the weird restrictions
6976 that Posix has about { }. Use better quoting.

7064 Factor functionality to..
7065 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
7066 `AC_SUBST($1)' in the public version.
7067 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
7068 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

7116 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
7118 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
7119 AC_LANG_PROGRAM, fixing a typo. Don't give details about
7120 the inner workings of AC_LANG_FUNC_LINK_TRY.
7121 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7122 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7123 by the function rather than ignoring it.
7124 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7125 comparing its address. Intel's interprocedural optimization was
7126 outsmarting the old heuristic. Problem reported by
7127 Mikulas Patocka.
7129 2005-10-19 Stepan Kasal <kasal@ucw.cz>
7131 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

7138 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7140 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7141 before removing it (chmod -R u+rwx); there are three instances of this.
7143 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7144 Stepan Kasal <kasal@ucw.cz>
7146 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7147 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7148 make its content writable before removing it. Remove an errorneous
7149 comment from the end, where the logs of the failed tests are copied
7150 to the main log file.
7152 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7154 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7155 in case the computer is too quick. Double quote the configure.ac
7156 snippets.
7158 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7159 problems if the testsuite were running too fast.
7161 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7163 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7164 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7165 (which belong to Xt, not X itself). See Debian bug 327655.
7166 * NEWS: Mention this.
7168 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7170 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7172 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7174 * config/move-if-change: Don't output "$2 is unchanged";
7175 suggested by Ben Elliston. Handle weird characters correctly.
7177 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7179 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7180 calls, so that the final expansion of this macro is shorter.
7181 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7182 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7183 the cleanup there. Use AS_VAR_* macros, to be more general.
7184 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7186 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7188 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7190 2005-09-01 Stepan Kasal <kasal@ucw.cz>
7192 * doc/autoconf.texi (Configuration Headers): Add an index entry
7193 for AH_HEADER.
7195 2005-08-26 Pavel Roskin <proski@gnu.org>
7197 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
7198 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
7199 running xmkmf.
7201 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7203 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7204 The previous patch didn't work, so try a better one.
7206 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7208 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7209 in the example. Reported by Bruno Haible.
7210 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7211 "if $undefined_var;" succeeds with my shell.
7213 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7214 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7215 but change the m4_divert_text to m4_divert_once.
7217 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7219 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7220 Work around bug in Solaris /usr/xpg4/bin/awk.
7221 The bug is present in at least Solaris 8 through 10.
7223 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7225 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7226 some evil values and relying on the fact that $* concatenates the
7227 parameters by the first character from IFS.
7229 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7230 Stepan Kasal <kasal@ucw.cz>
7232 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7233 first header appears, define AH_HEADER.
7234 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7235 Update limitations about when to call AC_CONFIG_HEADERS.
7236 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7237 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7238 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7239 ``Configuration Actions''; fix their index entries.
7241 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7242 options correctly. Process N-M as M-N if M is smaller than N.
7243 Process ranges correctly so that N-N will run only N.
7244 Sort and uniquify the tests that will be run. If there is more
7245 than one test, reinsert the banners for the tests.
7246 * tests/autotest.at (Keywords): Unmark XFAIL.
7248 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7250 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7251 before passing the macro name to AH_TEMPLATE.
7253 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7254 now opens log after option processing; in particular, --version
7255 and --help do not touch config.log.
7257 * Makefile.maint: Revert the change from 2005-08-12.
7259 2005-08-22 Stepan Kasal <kasal@ucw.cz>
7261 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
7262 common code to...
7263 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
7265 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7267 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7268 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7269 Language cleanup.
7271 * doc/autoconf.texi (Defining Symbols, Changed Results):
7272 Prepend to LIBS, not append, in examples.
7274 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7276 When building in place, set srcdir="."; suggested by Tim Van Holder.
7278 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7279 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7280 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7281 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7282 does not mean "no --srcdir option".
7284 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7286 * tests/autoscan.at (autoscan): New file.
7287 * tests/suite.at: Use it.
7288 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7289 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7291 * tests/autotest.at (Keywords): Test keywords combinations.
7293 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7295 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7296 add "2>&1"; gzip 1.2.4 prints help on stderr.
7298 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7300 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7301 was pushdef'ed twice while popped only once. Push it only once.
7302 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7304 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7306 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

7311 * Makefile.maint: Update from Bison.
7313 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7314 "<tab>" in comment, so that the point is understandable.
7316 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7318 Rewrite substantial part of lib/autoconf/status.m4.
7319 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7320 and CONFIG_COMMANDS are not processed in four separate loops.
7321 Instead, there is one main loop. This alows that the common code
7322 is expanded only once, thus config.status (and configure) is smaller.
7324 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7325 the AC_LIST_FILES and cousins macros are no longer used.
7327 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7328 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7329 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7330 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7331 contain the initialization, nor the for loop, nor the associated
7332 commands; all these go to ...
7333 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7334 _AC_OUTPUT_CONFIG_STATUS.
7335 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7336 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7337 (_AC_OUTPUT_FILE): The creation of the sed script ...
7338 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7339 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7340 _AC_OUTPUT_MAIN_LOOP.
7341 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7342 _AC_CONFIG_COMMANDS): Use ...
7343 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7344 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7345 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7346 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7347 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7348 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7349 ... new macros.
7350 (_AC_CONFIG_UNIQUE): Update.
7351 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7352 Replaced by this ...
7353 (_AC_LIST_TAGS): ... new common macro.
7354 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7355 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7356 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7357 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7358 this didn't belong to the `config commands' section.
7359 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7360 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7361 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7362 to the `config commands' section either.
7363 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7364 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7366 ... and many changes to the comments nearby.
7368 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7369 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7370 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7371 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7372 (#define header templates): The comment at the top of the generated
7373 header now includes the name(s) of the source file(s).
7375 Several unrelated small changes:
7377 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7378 parameter to AC_DIAGNOSE.
7379 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7380 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7381 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7382 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7383 with AU::AC_OUTPUT.
7384 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7385 in AC_OUTPUT doesn't double-quote it either.
7386 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7387 parameters.

7410 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7411 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7412 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7413 (AC_ARG_VAR): ... here.

7425 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
7426 to INIT_PREPARE.
7427 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
7428 its value to shell variable ac_precious_vars and call
7429 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.

7469 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
7471 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

7476 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
7477 sed substitution command, so that we allow | in program prefixes

7481 configure_input, top_builddir, srcdir, etc.
7482 * lib/autotest/general.m4 (AT_INIT): Likewise, for
7483 PATH_SEPARATOR in AUTOTEST_PATH.
7485 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

7493 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
7494 directories with weird names. Apparently some people like living

7519 for --help in that case.
7521 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
7522 matches the order of execution. No code changed.

7544 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
7545 (AC_SUBST): Call it.
7546 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7547 the directory specific variables; but don't call it for configure_input.
7549 2005-06-28 Derek Price <derek@ximbiot.com>
7551 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7552 addition.
7554 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
7556 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
7557 directory have inherent problems with special characters like spaces,

7575 variable into diagnostic. Make the diagnostic an error, not a warning,
7576 because we really don't support spaces and suchlike in dir names.
7577 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7578 Don't worry about backslashes in srcdir; it can't happen now.

7606 b, t, r, w commands require single space, while : cannot have any.
7607 (Special Shell Variables): Fix sed code this in the example.
7608 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
7609 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
7611 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
7612 expand to the empty list. Don't use two pairs of m4_changequote,
7613 it's not necessary.
7615 2005-06-20 Derek Price <derek@ximbiot.com>
7617 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.

7621 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
7622 * doc/autoconf.texi:
7623 Don't mention Solaris versions so much, if a
7624 problem is common to all extant versions of Solaris. Say "SunOS
7625 4" instead of "SunOS" for SunOS 4.
7626 (awk): Mention more of the limitations of traditional Awk.
7627 (cat): Don't talk about cat -v.
7629 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

7659 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
7660 quotes and backslashes. Patch from Derek Price.

7665 AS_TR_SH.
7667 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
7669 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7670 -u, since it outputs chatter if the input files are the same.
7671 Problem reported by Ralf Menzel.
7673 2005-06-08 Derek Price <derek@ximbiot.com>
7675 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7676 renaming them since they are about to be redefined anyhow.
7678 2005-06-08 Derek Price <derek@ximbiot.com>
7680 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7681 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7682 Move m4_undefine to alphabetical order.
7684 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
7686 * README: Recommend GNU M4 1.4.3 or later.
7687 * doc/autoconf.texi (Introduction): Likewise.
7688 Reword to avoid some formatting glitches.
7689 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
7690 Clarify explanation of HP compiler bug.
7691 Redo example output tp match current CVS snapshot.
7692 Use @example.org in email addresses when the examples
7693 might get inadvertently cut-and-pasted into user code.
7694 Remove example of autom4te usage that doesn't seem to work now.
7695 Use modern AC_INIT (except when the example is meant to be
7696 shown with Autoconf 2.13).
7697 Update ksh info for Solaris 9 and later.
7698 KB -> kB.
7699 Modernize description of Automake versions a bit.

7710 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7711 Tru64 ksh pattern matching bug. Reported against Libtool by
7712 Albert Chin <libtool@mlists.thewrittenword.com> and
7713 Nicolas Joly <njoly@pasteur.fr>.
7715 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7717 m4_cdr of one-member list was [[]] (one-member list containing an
7718 empty string) instead of [] (an empty list. Callers were skewed to
7719 match this misbehaviour. As a consequence of this:
7720 - m4_foreach([x], [], [foo]) expanded to `foo', while
7721 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7722 This bug has been fixed:
7724 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7725 expand to an empty string; print error msg if called without
7726 an argument list.
7727 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7728 misbehaviour; handle [] and [[]] correctly.

7736 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
7738 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7739 swallow records with more than 99 fields.
7740 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7741 parse the long line.
7743 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7745 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7746 swallow literals longer than 399. Reported by Ralf Wildenhues.

7752 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
7753 to gfortran, and make these the first two compiler names

7758 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
7759 (DISTCLEANFILES): Remove $(check_SCRIPTS).
7760 (testsuite): Make sure autotest.m4f is up-to-date before using it.

7764 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
7765 expression of unbounded size when processing the --list
7766 option. This runs afoul of a limit of 399 bytes per regular
7767 expression on AIX. Problem reported by Ralf Wildenhues.

7778 2005-05-31 Dan Manthey <dan_manthey@partech.com>
7780 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7781 now contain newlines, and substituted files must be referenced on
7782 a line alone; the sed scripts to substitute them are now very
7783 different.
7784 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
7785 commands can be put in a sed script portably.
7786 * doc/autoconf.texi (Setting Output Variables): Document above

7799 classes in shell scripts. The test was too brittle.
7801 2005-05-25 Stepan Kasal <kasal@ucw.cz>
7803 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

7834 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
7835 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
7836 (ac_top_builddir): ... this ...
7837 (ac_top_build_prefix): ... to this; the old name is also kept, for
7838 backward compatibility.
7839 (ac_top_builddir_sub): New variable, without the trailing slash,
7840 always nonempty.
7841 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
7842 * doc/autoconf.texi (Configuration Actions): Rename
7843 ac_top_builddir to ac_top_build_prefix.
7844 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
7845 at_top_builddir to at_top_build_prefix.
7846 * lib/autotest/general.m4 (AT_INIT): Likewise.
7848 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7850 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
7851 of confdefs.h .
7853 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7855 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7856 argument to m4_foreach. I guess it was necessary in the past,
7857 but I think it's a no-op now.
7859 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7861 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7862 ``cat <<_ACEOF'' commands to one.
7863 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
7864 * lib/autoconf/status.m4: On various places, use expr instead of
7865 ``echo|sed.''
7866 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
7867 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
7868 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
7869 a range.
7870 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
7871 the wrong patterns between ``case'' and ``esac.'' The previous
7872 code had false positives.
7874 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
7876 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
7877 as on 2005-05-02.
7878 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
7879 Mention LIBOBJDIR.

7919 2005-05-13 Stepan Kasal <kasal@ucw.cz>
7921 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
7922 check.
7923 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
7924 enough arguments, similarly as in m4_bpatsubsts.
7926 2005-05-12 Stepan Kasal <kasal@ucw.cz>
7928 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
7929 of absolute paths.
7931 2005-05-11 Stepan Kasal <kasal@ucw.cz>
7933 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
7934 for absolute directory names in one loop.
7935 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
7936 abbreviations of --version and --debug.
7938 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
7940 * doc/autoconf.texi (Autoconf Language): Be more precise about
7941 quoting rules. Problems noted by Stepan Kasal.
7942 Also, throughout this document, be more careful about white space.
7943 "blank", "white space", and "space" all have different meanings
7944 and we should be careful to say what we mean.
7946 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
7948 Fix C++ related problems reported by Werner Lemberg.
7949 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
7950 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
7951 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
7952 avoid problems with C++ and throw.
7953 * tests/compile.at: .cpp, not .cc.
7955 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
7957 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7959 * doc/autoconf.texi (Generic Functions): Typos.
7961 2005-05-02 Gary V. Vaughan <gary@gnu.org>
7963 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
7964 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
7965 set by latest automake.
7967 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7969 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
7970 outputs 0 on GNU/Linux these days.
7972 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
7974 * doc/autoconf.texi (Autoconf Language): Add more description
7975 about quoting heuristics.
7976 (Limitations of Builtins): Describe "set -" problems.
7978 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7980 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
7981 not newline.
7983 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
7984 by AC_DEFINE; it was a mistake.
7985 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
7987 2005-04-25 Stepan Kasal <kasal@ucw.cz>
7989 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
7991 2005-04-22 Stepan Kasal <kasal@ucw.cz>
7993 * doc/autoconf.texi (External Software): Quadrigraphs are not
7994 processed correctly in AS_HELP_STRING; avoid this in the examples.
7995 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7996 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7997 comment and reduce m4_default([foo], []) to [foo].
7998 (m4_strip): Update the explanation.
8000 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8002 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
8003 Remove core.conftest.* too; it's generated by Tru64 5.1.
8004 Problem reported by Jennis Pruett.
8005 * lib/autoconf/functions.m4
8006 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8007 Don't bother to remove core files; AC_RUN_IFELSE should do that
8008 for you.
8010 2005-04-19 Stepan Kasal <kasal@ucw.cz>
8012 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
8014 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
8016 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
8017 Report from Horst Wente.
8019 2005-04-15 Stepan Kasal <kasal@ucw.cz>
8021 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
8022 the comment.
8024 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
8026 * doc/autoconf.texi (External Software, Package Options): Add
8027 examples showing how to implement --with-* and --enable-* options.
8029 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8031 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
8032 as well as configure.in. Problem reported by Gregorio Guidi.
8034 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
8036 * doc/autoconf.texi (Particular Functions): Use gnulib's current
8037 pattern for alloca snippet.
8039 2005-04-04 Stepan Kasal <kasal@ucw.cz>
8041 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
8043 2005-04-01 Stepan Kasal <kasal@ucw.cz>
8045 * doc/autoconf.texi (Generic Programs): Fix a typo.
8047 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
8049 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
8050 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
8052 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8054 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8055 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8056 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8057 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8058 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8060 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8062 * NEWS: The configure command now warns you if you attempt to use
8063 a directory whose name contains a special character like space,
8064 newline, or "\".
8065 * doc/autoconf.texi (Installation Directory Variables): Allow
8066 "," in file names. Do not use \@; it's not a portable regexp.
8067 * bin/Makefile.am (edit): Likewise.
8068 * lib/Makefile.am (edit): Likewise.
8069 * tests/Makefile.am (edit): Likewise.
8070 * tests/semantics.at: Likewise.
8071 * tests/torture.at: Likewise.
8072 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
8073 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
8074 * doc/autoconf.texi (File System Conventions): Warn about
8075 unportable file names.
8076 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8077 (AC_INIT): Use it.
8078 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8079 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8080 ac_pwd, and quote srcdir.
8081 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8083 * doc/autoconf.texi: Fix some systematic formatting problems.
8084 ".)" needs a following @: if not at the end of a sentence, and
8085 similarly for "!)". "etc." should be preceded by a comma.
8086 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8088 2005-03-22 Bruno Haible <bruno@clisp.org>
8090 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8091 argument is often called 'build-aux'.
8093 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8095 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8096 macro AC_TRY_LINK is obsolete.
8097 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8098 `AC_CONFIG_FILES'.
8100 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8102 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8103 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8104 from a Common Lisp's `cl'.
8105 (AC_PROG_CXX): Behave according to the documentation: don't
8106 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8107 make the variable CCC precious; use `cl.exe', not `cl'.
8109 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8110 Alexandre Duret-Lutz <adl@gnu.org>
8112 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8113 /dev/null, as "configure" shouldn't read stdin, and this insulates
8114 us from problems (e.g., when testing for "cl"). Also, do this
8115 redirection before invoking "hostname" or "uname", and keep the
8116 original input stream available via...
8117 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8118 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8119 bother with "</dev/null" since it's now done at the top of
8120 'configure'.
8121 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8122 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8123 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8124 * doc/autoconf.texi (File Descriptor Macros): New section.
8125 (Printing Messages): Mention it.
8126 * tests/base.at (Input/Output): New test.
8128 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8130 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8131 newline if neither \c nor -n work, as that would output two
8132 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8134 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8136 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8137 This causes that any required macros inside will get before the if.
8138 * doc/autoconf.texi (autom4te.cache): A typo.
8140 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8142 Undo previous change, except keep the change to
8143 lib/autoconf/programs.m4 that replaced grep with shell
8144 pattern-matching. This is because net-snmp configure reads stdin.
8145 Reported by Noah Misch.
8147 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8149 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8150 from /dev/null, as "configure" shouldn't read stdin, and this
8151 insulates us from problems (e.g., when testing for "cl").
8152 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8153 before invoking "hostname" or "uname".
8154 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8155 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8156 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8157 "</dev/null" since it's now done at the top of 'configure'.
8158 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8159 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8160 Also, replace grep with shell pattern-matching, to save a process.
8162 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8164 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8165 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8166 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8167 compiler.
8169 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8171 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8172 grep -q isn't portable. Improve grep -s explanation.
8173 Problem reported by Dan Manthey.
8175 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8177 * doc/autoconf.texi (Special Shell Variables): Clarify
8178 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8180 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8182 * doc/autoconf.texi: Use @acronym for DJGPP.
8183 Fix some @code's that should have been @env's, and vice versa.
8184 Sort environment variable names.
8185 Mention that shells no longer inherit IFS.
8186 Don't recommend PATH_SEPARATOR=';' so strongly.
8187 Mention that $RANDOM might expand to the empty string.
8188 "symlink" and "soft link" -> "symbolic link".
8189 Improve mktemp description (reported by Bruno Haible).
8191 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8193 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8194 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8195 Likewise.
8196 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
8197 Likewise.
8199 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8201 * NEWS: Mention AT_COPYRIGHT.
8203 * tests/local.at (AT_CMP): Use diff directly on input files rather
8204 than copying them.
8206 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8207 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8209 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8210 and Paul Eggert <eggert@cs.ucla.edu>
8212 * tests/autotest.at (Empty test suite): New test.
8213 * tests/torture.at (Substitute and define special characters)
8214 (Substitute a 2000-byte string, Define to a 2000-byte string)
8215 (Substitute a newline, Define a newline): New tests.
8217 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8219 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
8220 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8221 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8222 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8223 (Standard regular expressions): New test.
8224 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8225 excess test name quoting.
8226 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8227 CPPFLAGS to `configure' instead of setting it in `configure'.
8229 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8230 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8231 on some platforms.
8233 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
8234 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
8236 * tests/local.at (AT_CMP): New macro.
8237 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
8238 (AC_SAVE_STATE): Move environment grep...
8239 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
8240 (AT_CONFIG_CMP): New macro.
8241 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
8242 * tests/c.at (Extensions): Do not exit early.
8243 * tests/atlocal.in: Inherit $GREP.
8245 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
8246 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
8248 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
8249 (AC_COPYRIGHT): Factor header comment portion out and move into...
8250 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
8251 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
8252 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
8253 --version output.
8254 * tests/local.at: Add Autoconf test suite copyright notice.
8255 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
8257 2005-02-04 Bruno Haible <bruno@clisp.org>
8258 and Paul Eggert <eggert@cs.ucla.edu>
8260 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
8262 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
8264 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
8265 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

8328 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8329 Update the long comment explaining it.
8331 m4_require no longer writes an ``is required by'' line to the
8332 execution stack. It contains only one bit of non-redundant
8333 information: that the macro was required, not called. And even
8334 this bit is useless in most situations: have you ever met a macro
8335 which both calls and requires the same macro?
8337 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8338 (_m4_defun_pro_outer): ... only via this macro, for the outermost

8346 * tests/m4sugar.at (m4_require): Expect output without the
8347 ``is required by'' messages.
8349 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8351 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
8352 rather than x for expr.
8354 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
8355 this is safe.
8356 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.

8383 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
8385 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
8386 Warn about newline stripping in `` and $(). Update Solaris
8387 version to 9.

8391 stripping.
8393 2005-01-19 Stepan Kasal <kasal@ucw.cz>

8413 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
8415 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
8417 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

8440 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
8441 otherwise.
8442 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
8443 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8444 stored in _m4_divert_diversion or _m4_divert_dump.
8445 (m4_divert_pop): When the parameter is given, compare the symbolic
8446 name with the last diversion pushed on the stack. Previously, the
8447 current diversion was compared with the numeric value of the
8448 diversion given as the parameter.
8449 (m4_require): If the macro hasn't been expanded yet, call ...
8450 (_m4_require_call): this new macro.

8483 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

8536 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
8537 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

8727 * tests/Makefile.am (installcheck-local): Add check-local dependencies.
8729 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
8731 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
8732 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
8733 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
8734 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
8736 2004-12-07 Stepan Kasal <kasal@ucw.cz>
8738 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous
8739 patch: extra "-l"s.
8741 2004-12-06 Paul Eggert <eggert@cs.ucla.edu>
8743 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Check libc before
8744 looking elsewhere for getmntent. Problem reported by Mark D. Baushke.
8745 * doc/autoconf.texi (Particular Functions): Mention new behavior.
8747 2004-12-03 Stepan Kasal <kasal@ucw.cz>
8749 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
8750 out the common code to ...
8751 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
8752 value of the #define--default to 1, iff the macro was called
8753 with exactly one parameter.
8755 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
8757 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
8758 "char c = '\200';" rather than "char c = 0x80;" as the
8759 latter doesn't conform to the strict C standard due to
8760 overflow on signed char hosts.
8762 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
8763 to -qlanglvl=ansi. We don't want to disable extensions.
8765 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
8767 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
8768 (Using Autotest, testsuite Scripts, Writing testsuite.at):
8769 Reword slightly to avoid some English-language problems noted

8781 along with some nearby cruft.
8782 * doc/autoconf.texi (Libtool): Libtool can be used without
8783 Automake (not without Autoconf).
8784 (Introduction): Mention lists.gnu.org.
8785 * BUGS: Don't mention bugs.gnu.org.
8786 Remove mention of ancient libtool compatibility problem.
8787 * NEWS: Mention that bugs.gnu.org is kaput.
8788 * README: Likewise. Mention where mailing list archives can be found.
8790 2004-11-28 Stepan Kasal <kasal@ucw.cz>

8810 in my editing of the previous patch. Problem reported
8811 by Alexandre Duret-Lutz.
8813 2004-11-22 Stepan Kasal <kasal@ucw.cz>
8815 * doc/autoconf.texi (Autoconf Language): Explain that
8816 ``descriptions'' may not be double quotes.
8817 (Quotation Rule Of Thumb): Likewise.
8818 (Pretty Help Strings): Likewise; remove the wrong comment;
8819 simplify the examples and improve their quoting.
8821 2004-11-13 Stepan Kasal <kasal@ucw.cz>
8823 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
8824 the $1_found variable, don't test whether the file is executable;
8825 Both things are checked ...
8826 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
8827 the former ``test -f''.
8828 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
8830 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>
8832 * doc/autoconf.texi (Limitations of Usual Tools): Avoid cp -r;
8833 use cp -R instead.
8835 2004-11-10 Derek R. Price <derek@ximbiot.com>
8837 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
8838 limitations. Reorder paragraphs for clarity.
8840 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
8842 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
8843 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
8844 variants", "Unix", and some related minor wording fixups.
8846 (Shellology, Special Shell Variables): Document that the Zsh
8847 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
8848 to Alexandre Duret-Lutz for this info.

8857 of putenv. Problem reported by Michael Wardle.
8859 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
8861 * doc/autoconf.texi (auindex): New macro.
8862 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
8863 Problem reported by Stepan Kasal.
8865 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
8867 Fix problems reported by Andreas Buening in:
8868 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
8869 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
8870 in test makefile.
8871 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
8872 readable; it's not true in OS/2-emx.
8874 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
8876 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
8877 "/usr/include", clear ac_x_includes instead of leaving it as "no"
8878 (trivial change). Problem and patch reported by Andrew Church in:
8879 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
8881 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
8883 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
8884 three args in examples. Problem reported by Frederik Fouvry in:
8885 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
8886 Also, fix some minor spacing and punctuation bugs.
8888 2004-09-02 Akim Demaille <akim@epita.fr>
8890 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
8891 "case" to restore ordering.
8892 Reported by Stepan Kasal.
8894 2004-08-26 Akim Demaille <akim@epita.fr>
8896 * doc/autoconf.texi: Minor typos and stylos.
8898 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
8900 * configure.ac (AC_INIT): Bump to 2.59c.
8902 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
8904 Version 2.59b.
8906 * README: Add advice about m4 1.4.2.
8908 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
8909 texinfo.tex for now (done by hand now).
8910 * Makefile.maint (wget_files, cvs_files):
8911 Remove ansi2knr.c; nobody uses it.
8912 (ansi2knr.c-url_prefix): Remove.
8913 (cvs-update): Fix test for failure. I don't know why it ever
8914 worked...
8916 * doc/autoconf.texi: Update URLs, some of which went stale.
8917 Use @uref rather than @href.
8919 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
8920 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
8922 * config/config.guess, config/config.sub, config/elisp-comp,
8923 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
8924 doc/fdl.texi, doc/standards.texi: Sync with master copy.
8926 * NEWS, TODO, configure.ac, bin/autoscan.in,
8927 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
8928 doc/install.texi, lib/Autom4te/Configure_ac.pm,

8932 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
8933 tests/tools.at, tests/torture.at:
8934 Use "file name" rather than "filename" or "path",
8935 to be consistent with the terminology of the GNU coding standards.
8937 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
8939 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
8940 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
8941 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
8942 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
8944 More fixes to support spaces in the name of the build directory.
8945 This isn't a complete fix but it's an improvement.
8947 * bin/autoconf.as (autom4te_options): New var.
8948 Use it instead of appending to AUTOM4TE, so that we can allow
8949 spaces in the build directory's absolute name.
8950 * bin/autoheader.in ($autoconf): Allow spaces in file names.
8951 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
8952 AT_CHECK_NOESCAPE): Likewise.
8953 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
8954 main program): Likewise.
8956 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
8958 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
8959 From Ralf Corsepius in:

8962 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
8964 * doc/autoconf.texi (Function Portability): Document isinf and
8965 and isnan. From a suggestion by Kevin Ryde.
8967 * lib/Autom4te/General.pm (END): Return correct exit status even
8968 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
8970 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
8972 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
8973 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
8974 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
8976 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
8978 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
8979 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
8980 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
8981 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
8982 * lib/autom4te.in (Automake-preselections): Preselect
8983 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
8985 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
8987 * lib/autom4te.in (Automake-preselections): Preselect
8988 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
8989 trace them.
8991 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
8993 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
8994 Tru64.
8995 * doc/autoconf.texi (Shellology): Mention BIN_SH.
8996 Document problem with "`""`" in pdksh POSIX mode.
8998 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
9000 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9001 with pdksh, too. Problem reported by Patrick Welche via
9002 Gary V. Vaughan.
9003 * doc/autoconf.texi (Shellology): Note that set -o posix is
9004 useful for pkdsh, too.
9006 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9008 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9009 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9010 Don't fail if ENV or BASH_ENV is readonly.
9011 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9012 etc. are read only. Problem reported by Ludovic Courtes.
9014 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9016 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9017 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9018 (trivial change)
9020 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9022 * doc/autoconf.texi (File System Conventions): Warn about
9023 names like "aux". Problem reported by Eric Blake.
9025 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9026 by zero instead of array size, so that we can use any arithmetic
9027 constant expression (instead of requiring an integer constant
9028 expression). This allows us to test expressions like DBL_MAX <
9029 LDBL_MAX, which didn't conform to the C standard using the old
9030 method.
9031 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9032 now that we can do floating-point tests at compile time.
9034 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9036 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9037 and LDBL_EPSILON, as the resulting expression isn't an
9038 integer constant expression and violates the C standard.
9039 Problem reported by Nelson H. F. Beebe. Also, check
9040 for "L" suffix, and check that long double doesn't have
9041 worse range or precision than double, that mixed-mode
9042 arithmetic doesn't generate a diagnostic, that double
9043 constants fit in long double.
9045 2004-06-03 Kevin Ryde <user42@zip.com.au>
9047 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9048 malloc(0) and realloc(NULL,size).
9050 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9051 Bob Proulx.
9053 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9055 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9056 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9057 by Jim Meyering.
9059 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9061 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9062 can be rewritten using if-then-else. Suggested by Bruno Haible.
9064 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9066 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9067 Problem reported by Stepan Kasal.
9069 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9071 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9072 change). Patch reported by Ralf Wildenhues in
9073 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9075 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9076 function F exists if the compiler and linker let you compile an
9077 expression like (F != 0). Recent versions of GCC optimize away
9078 the reference to F in that case, since every function address must
9079 be nonzero, so the link succeeds even if F does not exist.
9080 Problem reported by Manu in
9081 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9083 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9084 "Unix". Many uses changed.
9085 (Limitations of Builtins): Explain better why the ! command isn't
9086 portable.
9088 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9090 * lib/autom4te.in (Automake-preselections): Preselect
9091 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9093 2004-05-19 Kevin Ryde <user42@zip.com.au>
9095 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9096 referencing AC_FUNC_STRERROR_R.
9098 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9099 note pessimistic assumption when cross compiling.
9101 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9103 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9104 (until 2004) invoked subcommands with sh -e, contra POSIX.
9105 Reported by Kevin Ryde.
9107 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9109 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9110 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9111 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9112 `test -f " /usr/bin/grep"', which _always_ failed.
9113 (AC_PROG_SED): Ditto bogus PATH fix.
9114 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9115 requires that grep correctly supports _multiple_ `-e' options, rather
9116 than stating only that grep should accept `-e'.
9118 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9120 Port to C99, which requires that 'exit' be declared.
9122 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9123 to ensure that stdlib.h is included.
9124 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9125 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9126 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9127 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9128 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9129 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9130 when using 'exit' in a test; C99 requires that 'exit' be declared.
9132 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9134 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9135 now prefers 'grep' implementations that accept -e.
9136 (Limitations of Usual Tools): Describe problems of traditional
9137 egrep and fgrep with long input lines, and of traditional grep
9138 with -e.
9139 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9140 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9141 All callers changed. Append /usr/xpg4/bin to the PATH, for
9142 Solaris.
9143 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9144 the user with complaints about multiple -e options.
9145 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9146 Define it with AC_PROG_GREP.
9147 * configure.ac (AC_PROG_GREP): Add.
9148 * lib/freeze.mk (GREP): New macro.
9150 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9152 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9153 a possible candidate only after all others fail, rather than
9154 consulting it first. This improves backward compatibility by
9155 better reflecting the way shell selection occurred in previous
9156 versions of Autoconf, and should help to avoid triggering latent
9157 problems in other packages, such as the one in Automake where zsh
9158 is not handled robustly:
9159 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9160 Although it is not Autoconf's responsibility to work around
9161 problems in Automake, it nevertheless makes sense to avoid
9162 introducing unnecessary incompatibilites.
9164 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9165 Gary V. Vaughan <gary@gnu.org>
9167 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9168 how deeply nested we are when a suitable tool is found, set the
9169 ac_path_TOOL_found flag.
9170 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9171 nested we are in this macro. Break out of all 3 nested loops if
9172 ac_path_TOOL_found is set.
9174 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9176 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9177 of the _AS_PATH_WALK loop too if GNU flavor is found.
9179 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9181 * doc/autoconf.texi (Limitations of Make): Update documentation
9182 for `$<'. New entry `Long lines', based on a report from Simon
9183 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9184 paragraph about DJGPP, based on a mail from Richard Dawe.
9186 2004-04-20 Paul Eggert <eggert@twinsun.com>
9188 * tests/c.at (C keywords): Don't assume that GCC supports
9189 "restrict" and "inline", as sufficiently-old GCC versions do not
9190 (also, GCC configured to be in pedantic C89 mode does not).
9191 Problem reported by Sumit Pandya in:
9192 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9194 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9195 consider -g to work if it generates warnings when plain compiles
9196 don't. Problem reported by Braden McDaniel in:
9197 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9199 * doc/autoconf.texi (Slashes): New section, to document a problem
9200 reported by Jim Meyering in:

9208 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9210 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9211 best tool so far counter rely on the tool path variable name to
9212 avoid checks for one tool being affected by the results of running
9213 the length check on a previous tool.
9215 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9216 match expression argument, as different greps have different
9217 regular expression flavours.
9218 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9219 literals.
9220 (AC_PROG_EGREP): Pass 'EGREP$'.
9221 (AC_PROG_GREP): Pass 'GREP$'.
9223 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9225 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9226 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.

9230 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9231 Types, Specific Compiler Characteristics, System Services,
9232 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9233 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9234 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9235 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9236 Likewise.
9237 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

9246 2004-03-28 Paul Eggert <eggert@twinsun.com>
9248 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9249 now defines HAVE_DECL_TZNAME if it is declared, when
9250 HAVE_STRUCT_TM_TM_ZONE is not defined.
9251 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9252 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
9253 for HAVE_TZNAME.
9255 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
9257 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
9258 superfluous backslashing of quotes (") in sed expressions;

9263 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
9264 Fortran compiler is ifort, also added pghpf; thanks to Nelson
9265 H. F. Beebe for the bug report.
9267 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
9269 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
9270 quoted -cmdline argument in Portland Group compiler (bug
9271 reported by Jeffrey J. Barteet).
9273 2004-03-25 Kevin Ryde <user42@zip.com.au>
9275 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
9276 (Run Time): ... here, where it's now mentioned.

9280 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
9281 inherits from language Autoconf-without-aclocal-m4.

9296 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
9297 AC_CHECK_TOOLS.
9298 (Specifying Names): Document the reason for these future
9299 behavioral changes.
9300 * tests/mktests.sh: Do not generate tests for the
9301 new macros.
9302 * NEWS: Document these changes.
9304 * doc/autoconf.texi: Avoid macros with unbraced arguments,
9305 they make TeX hang up.
9307 2004-03-15 Paul Eggert <eggert@bogus.example.com>
9309 * NEWS: New macro AC_CHECK_ALIGNOF.
9310 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
9311 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
9312 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
9313 vowel.
9314 (AC_CHECK_ALIGNOF): New macro.
9315 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.

9319 2004-03-03 Paul Eggert <eggert@twinsun.com>
9321 * bin/Makefile.am (edit): Don't use $< in a context where
9322 POSIX doesn't require support for it. Use $@.in instead.
9323 Problem reported by Anthony N. Frasso in
9324 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
9325 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
9327 2004-02-23 Gary V. Vaughan <gary@gnu.org>
9329 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
9330 from the next generation of Libtool.
9331 * lib/autom4te.in (Autoreconf-preselections): Ditto.
9333 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9335 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
9336 is not always thread-safe. Report from Nathanael Nerode.
9338 2004-02-18 Paul Eggert <eggert@twinsun.com>
9340 Fix a dependencies problem, stemming from a Autoconf 2.59 build
9341 problem on QNX reported by Stephen Rasku in
9342 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
9344 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
9345 $(m4sh_m4f_dependencies); this removes a FIXME.
9346 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
9347 (MAINTAINERCLEANFILES): Split into pieces,
9348 one per related section. Add $(srcdir)/wrapper.in.
9350 2004-02-09 Paul Eggert <eggert@twinsun.com>
9352 * doc/autoconf.texi (Setting Output Variables): Emphasize that
9353 AC_SUBST provides no portable way to escape literal newlines.
9355 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9356 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9357 Darwin uses -lcrt2.o and there's little point to cataloging all
9358 the system variants. Partial fix reported by Andreas Waechter in:
9359 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
9360 for bug reported by Nelson H. F. Beebe in:

9366 suggested by Paul Eggert.
9367 * lib/autoconf/autoupdate.m4: Correct reference to
9368 acobsolete.m4, suggested by Alexandre Duret-Lutz.
9370 2004-02-02 Paolo Bonzini <bonzini@gnu.org>

9375 the behavior of the third argument.
9376 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
9377 correctly the behavior of the third argument. Document
9378 what the three macros that AU_DEFUN defines do. Fix
9379 warning message when the third argument includes $0

9382 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
9383 Eric Sunshine <sunshine@sunshineco.com>
9384 Paul Eggert <eggert@twinsun.com>
9386 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
9387 (AS_INIT): Output shell initialization there. Removed optional
9388 parameter. Expand _AS_SHELL_FN_SPY.
9389 (AS_INIT_WITH_SHELL_FN): Removed.
9390 (_AS_SHELL_FN_SPY): New macro.
9391 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
9392 macros.
9393 (AS_SHELL_SANITIZE): Remove loop to find better shell
9394 and documentation for the parameter.
9395 (_AS_DETECT_BETTER_SHELL): Move it here.

9397 (_AS_RUN): Move it here, support testing with eval.
9398 (AS_REQUIRE_SHELL_FN): Require shell functions when
9399 it is used.
9400 (_AS_LINENO_WORKS): Put around braces, we do not
9401 trigger the bash bug anymore.
9402 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
9403 use AS_INIT_WITH_SHELL_FN.
9404 * bin/autoconf.in, tests/wrapper.in: Regenerated.
9406 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
9408 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
9409 * doc/autoconf.texi: Don't say that the third parameter
9410 is broken.
9411 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
9412 (AU_DEFUN): Honor the third parameter, create autoupdate
9413 macros with AU_DEFINE.
9414 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
9415 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

9417 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
9418 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

9434 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
9435 2003 (except 1997) to the list of copyright years. This undoes
9436 the 2003-05-22 change, which removed the older years from the list.
9437 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
9439 2004-01-27 Gary V. Vaughan <gary@gnu.org>
9440 Albert Chin-A-Young <china@thewrittenword.com>

9444 possible.
9445 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
9446 AC_PROG_GREP.
9447 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available

9449 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
9450 _AC_PROG_GREP, and AC_PROG_SED.
9451 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
9452 longest input length accepted by a command.
9453 (AC_PROG_SED): Use it.
9454 * doc/autoconf.texi (Particular Programs): Document the changes.
9455 * NEWS: Updated.
9457 2004-01-27 Paul Eggert <eggert@twinsun.com>

9479 sources.
9481 2004-01-26 Paul Eggert <eggert@twinsun.com>
9483 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9484 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9485 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9486 not <inttypes.h>. Problem reported by Tim Mooney in
9487 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9488 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9489 Likewise.
9491 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9492 otherwise "make check" fails because it forbids cmp (I guess
9493 because cmp treats files as binary on DOS-like systems).
9495 * tests/mktests.sh: Update copyright date to 2004, since some tests
9496 have changed in 2004.
9498 2004-01-23 Gary V. Vaughan <gary@gnu.org>
9500 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
9501 non-truncating sed or gsed program in PATH.
9502 * tests/acprograms.at: Add it.

9504 * NEWS: Updated.
9506 2004-01-15 Paul Eggert <eggert@twinsun.com>
9508 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9509 -std1 disables some useful extensions on Tru64. Problem reported
9510 by N. Lichtmaier in
9511 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
9513 2004-01-14 Paul Eggert <eggert@twinsun.com>
9515 * doc/autoconf.texi (Programming in M4sh): Document that
9516 AS_MKDIR_P succeeds if the destination is a symbolic link
9517 to an existing directory.
9518 (Limitations of Usual Tools): Note that mkdir -p might not
9519 succeed on symlinks to directories.
9521 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9523 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
9524 * bin/autoheader.in: Grammar fix in message.
9525 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
9526 Test for dir before calling mkdir -p. (trivial changes)
9528 2004-01-13 Eric Blake <ebb9@byu.net>
9530 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
9531 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
9533 2004-01-10 Jim Meyering <jim@meyering.net>
9535 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
9537 2004-01-09 Paul Eggert <eggert@twinsun.com>
9539 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9540 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9541 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9542 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9543 AC_COMPILE_IFELSE, since we now assume our caller invokes
9544 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9545 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9546 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9547 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9549 2004-01-07 Paul Eggert <eggert@twinsun.com>
9551 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9552 `"'...'"`, as it's confusing (and I suspect it may not work on
9553 some platforms). The code was incorrect anyway, as it assumed
9554 that \$ evaluated to itself in that context. Reported by
9555 Alexandre Duret-Lutz.
9557 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9559 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
9560 and _LT_AC_TAGCONFIG.
9562 2004-01-06 Paul Eggert <eggert@twinsun.com>
9564 * doc/autoconf.texi (One Macro Call): Fix an incorrect
9565 example, and add more examples. Reported by Eric Sunshine.
9567 2004-01-05 Paul Eggert <eggert@twinsun.com>
9569 * doc/autoconf.texi (Limitations of Usual Tools):
9570 Remove warning against "rm -fr" introduced yesterday; it
9571 was a false alarm.
9573 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
9574 autoscan, autoupdate, ifnames): Don't use chmod -w.
9575 * lib/Makefile.am (autom4te.cfg): Likewise.
9576 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
9577 "chmod -w".

9580 Paolo Bonzini <bonzini@gnu.org>
9582 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
9583 by doing lineno substitution only on lines containing "$LINENO".
9585 2004-01-04 Paul Eggert <eggert@twinsun.com>
9587 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
9588 Use "rm -f" to remove conftest.sed, not plain "rm".
9589 Bug reported by David Relson in
9590 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
9592 * Makefile.am (autom4te-update):
9593 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
9594 * Makefile.maint (my-distcheck, do-po-update): Likewise.
9595 * doc/autoconf.texi (Guidelines): Likewise.

9604 * doc/autoconf.texi (Limitations of Usual Tools):
9605 Warn against "rm -fr".
9607 2004-01-03 Paul Eggert <eggert@twinsun.com>
9609 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9610 -c -o might not work. From a suggestion by Kevin Ryde.

9612 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9613 Don't put '-o' after non-options, as POSIX doesn't allow this.
9614 Mention that cc's name might be gcc or c89 or whatever.

9682 (&sizes): New.
9683 Use them.
9684 No longer rely on Gnus to inline the list of signatures: compute
9685 them on the fly.
9687 2003-11-24 Akim Demaille <akim@epita.fr>
9689 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can
9690 override some files.
9691 (Input): AC_CONFIG_AUX_DIR(aux) is a bad idea on DOS.
9692 From Debian Autoconf 2.58.
9694 2003-11-24 Akim Demaille <akim@epita.fr>

9738 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

9758 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

9894 cross test.
9896 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
9898 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
9899 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

9911 Problems reported by Eric Sunshine.
9913 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
9915 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
9916 -mGLOB_options_string stuff for Intel ifc, which can cause
9917 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
9918 pattern-matching instead of grep.

9940 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
9941 cache variable instead of $G77 to decide whether to include -O2,
9942 since $G77 is specific to Fortran 77.

9946 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

9949 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9951 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
9952 arguments so that it can be used with syntax identical to
9953 AC_PROG_F77, and so that we can more easily decide to
9954 remove/deprecate the DIALECT optional argument in the future if it
9955 proves troublesome.
9956 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
9957 non-freeform-supporting compilers. Document freeform flags.

9964 2003-10-03 Akim Demaille <akim@epita.fr>
9966 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
9967 * bin/autoreconf.in (autoreconf_current_directory): Create the

9971 2003-10-03 Akim Demaille <akim@epita.fr>
9973 * configure.ac: Quotation and formatting changes.

9996 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.

10022 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10023 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
10024 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
10026 2003-09-26 Akim Demaille <akim@epita.fr>
10028 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10029 directory for AC_CONFIG_COMMANDS' first argument exists.
10030 This makes valid the invocation of _AC_SRCPATH that follows.
10031 Reported by Eric Sunshine.
10032 * doc/autoconf.texi (Configuration Commands): Adjust.
10034 2003-09-26 Akim Demaille <akim@epita.fr>
10036 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
10037 Reported by Ralf Corsepius.
10039 2003-09-26 Akim Demaille <akim@epita.fr>
10041 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
10042 arguments.

10055 The test suite are sometimes assigning timings incorrectly.
10056 Reported by Henk Krus.
10057 Diagnosed by Nicolas Joly.
10059 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10060 AT_help_all.
10061 Instead of making AT_help a sequence of assignments to grow
10062 $at_help_all, just make AT_help_all be the growing contents of
10063 $at_help_all, and make a single assignment in...
10064 (AT_INIT): here.
10065 (at_times_skip): Flip the meaning and rename as...
10066 (at_times_p): this.
10067 (AT_INIT): When summarizing the test that ran, remove
10068 $at_times_file after use, and check it is present before trying to
10069 use it.

10077 (ifnames): chmod -w.
10078 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10079 executables, not bin/ executables! Otherwise all the magic needed
10080 to find non installed files is turned off. This caused a failure
10081 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10082 as found in its environment (sent by tests/autoreconf): pointing
10083 to bin/autom4te that could not find its files.
10084 * tests/mktests.sh: Force the replacement of generated files, for
10085 the sake of "mv" program that are interactive when overwriting a
10086 -w file.
10087 * config/install-sh: Upgrade from CVS Automake.
10089 2003-09-23 Paul Eggert <eggert@twinsun.com>

10097 Trivial change to support GCC's configuration procedure.

10157 From a suggestion by Ian Lance Taylor in
10158 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
10160 2003-09-05 Paul Eggert <eggert@twinsun.com>
10162 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,

10178 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10180 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10182 Add support for newer Fortran dialects. The F77 interface is
10183 unchanged, and continues to support Fortran 77. New FC macros
10184 correspond to all the old F77 macros, with output variables FC,
10185 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10186 available dialect, but older dialects can be specified. There are
10187 new macros AC_FC_SRCEXT to set the source extension, and
10188 AC_FC_FREEFORM to accept free-form source files.

10219 'touch -r' have.
10221 2003-08-27 Akim Demaille <akim@epita.fr>
10223 * tests/m4sugar.at (cross_warning): Make sure to enable the
10224 output, so that we can track spurious m4sugar output.
10225 * tests/local.at: Require 2.57.
10226 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that

10281 2003-08-22 Akim Demaille <akim@epita.fr>
10283 Output stack traces in warnings.
10285 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
10286 Replace the former...
10287 (m4_warn): Pass the call stack to _m4_warn.
10288 * bin/autom4te.in: Adjust to output the call stack.
10289 * tests/m4sugar.at (m4@&t@_warn): Adjust.

10299 (&verbose): Remove.

10308 * bin/autoheader.in (&parse_args): Use &parse_warnings and
10309 &parse_WARNINGS.
10310 ($help): Use Autom4te::ChannelDefs::usage.
10311 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10312 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10314 2003-08-21 Akim Demaille <akim@epita.fr>
10316 First stab at preserving warnings between calls to autom4te,
10317 including when the cache is used.
10319 There are still several issues: (i) there are too many runs of m4
10320 (one for include, one for warnings, and some more), (ii) warnings
10321 spreading on several lines are not handled gracefully, (iii) the
10322 code meant to have the call stack display for errors does not work
10323 (its handling should move from m4 to autom4te).
10325 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10326 Use them.
10327 (@preselect): Add m4_warn.
10328 ($exit_status): Remove, use $exit_code.
10329 ($help): Use Autom4te::ChannelDefs::usage.
10330 (&handle_m4): No longer define the m4_warnings.
10331 At each run, extract and report the warnings.
10332 Always cache the result, including if the exit status is on
10333 failure, since if nothing changes, we should result in the same
10334 failure, hence we can use the cache.
10335 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10336 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10337 Remove.
10338 (m4_warn): Redefine as a do-nothing: it is its invocation that
10339 matters, as warnings are now reported via traces.
10340 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10341 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10342 the latter reveals calls to the former.
10344 Adjust the tests.
10346 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
10348 2003-08-21 Akim Demaille <akim@epita.fr>
10350 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
10351 Use them.
10353 2003-08-21 Akim Demaille <akim@epita.fr>
10355 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
10356 forward order.
10357 * lib/Autom4te/ChannelDefs.pm: Doc typos.
10358 (&parse_warnings): Accept a list of warning requests.
10359 (&usage): Return a string, not a side effect.
10360 (cross): New warning category.
10362 2003-08-21 Akim Demaille <akim@epita.fr>
10364 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
10365 (&require_configure_ac): Accept an optional directory argument.
10366 ($configure_ac): Remove.
10367 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
10368 (&catfile): Remove.
10369 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
10370 * bin/autoscan.in: Adjust.
10372 2003-08-20 Akim Demaille <akim@epita.fr>
10374 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
10375 Reported by Alexandre Duret-Lutz.
10377 2003-08-20 Akim Demaille <akim@epita.fr>
10379 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10380 * bin/autom4te: Adjust.
10381 In particular, be Autoconf tools are really silent when properly
10382 working, bind the verbosity of the 'note' channel to $verbose.
10383 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10384 (&xsystem, &contents): Remove, since they are exported by...
10385 * lib/Autom4te/FileUtils.pm: this.
10386 More perldoc.
10387 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
10388 * lib/Autom4te/FileUtils.pm: here.
10390 2003-08-20 Akim Demaille <akim@epita.fr>
10392 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
10393 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
10394 from CVS Automake.
10396 2003-08-20 Akim Demaille <akim@epita.fr>
10398 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
10399 (autom4te-update): New.
10400 * Makefile.cfg (update): Bind autom4te-update.
10402 2003-08-19 Derek Price <derek@ximbiot.com>
10404 * lib/autotest/general.m4: Comment various HELP_* diversions.

10408 package specific options and associated help.
10410 2003-08-19 Akim Demaille <akim@epita.fr>

10416 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>

10426 * doc/autoconf.texi (autom4te Invocation): Mention
10427 Autoconf-without-aclocal-m4.
10429 2003-08-18 Derek Price <derek@ximbiot.com>
10431 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
10432 RUN-IF-PASS optional arguments.

10445 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
10446 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
10447 shorter column three. Add DESCRIPTION to log file content.
10449 2003-08-13 Derek Price <derek@ximbiot.com>
10451 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
10452 output.

10456 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
10457 (AT_CHECK_NOESCAPE): Move core functionality to...
10458 (_AT_CHECK): ...this new macro.
10460 2003-08-07 Derek Price <derek@ximbiot.com>
10462 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
10463 (AT_CHECK_NOESCAPE): ...to this new macro.
10465 2003-07-31 Paul Eggert <eggert@twinsun.com>
10467 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
10468 in Bash 2.01. Problem reported by Brian Gough in
10469 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.

10473 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore

10476 2003-07-07 Paul Eggert <eggert@twinsun.com>
10478 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
10479 inside '#ifndef __cplusplus'. Problem reported by
10480 Bob Friesenhahn.
10482 2003-07-06 Bill Clarke <llib@computer.org>
10484 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
10485 'long', not 'int', for benefit of Sun's recent C++ compilers
10486 (trivial change). See:
10487 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
10488 (This really should be 'intptr_t', not 'long', but that would
10489 take more work.)
10491 2003-06-25 Akim Demaille <akim@epita.fr>
10493 * lib/Makefile.am (autom4te.cfg): Make it read only.
10494 Depend on Makefile since it contains substitutions.
10495 From Paolo Bonzini.

10497 This change was made on autom4te.cfg which is generated.

10503 From Gareth McCaughan.
10505 2003-06-23 Akim Demaille <akim@epita.fr>
10507 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10508 not all of them. This fixes 1. the fact that when testing
10509 Autoconf there are many many config.log, 2. the incorrect use of
10510 top_srcdir to find config.log.
10511 Don't mix the detailed output of failed test with the summary of
10512 failures. Rather, append detailed log afterwards.
10514 2003-06-23 Akim Demaille <akim@epita.fr>
10516 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

10521 * tests/torture.at (#define header templates): Don't use quotes in
10522 C++ comments as it puzzles Emacs' sh font-lock-mode.
10524 2003-06-23 Akim Demaille <akim@epita.fr>
10526 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
10527 * lib/autom4te.cfg (args): Add local.at? for Autotest args.

10537 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
10538 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
10539 ensuring we add -std1 for full-ANSI.
10541 * doc/autoconf.texi (hdrindex): New macro.
10542 Add index entries for portability of various standard header files.
10544 2003-06-20 Akim Demaille <akim@epita.fr>
10546 * configure.ac: Bump to 2.57b.
10548 2003-06-20 Akim Demaille <akim@epita.fr>

10573 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
10574 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
10575 (AT_INIT): Support for expected failures.
10577 2003-06-02 Akim Demaille <akim@epita.fr>
10579 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space

10584 PODify.
10586 2003-05-28 Paul Eggert <eggert@twinsun.com>
10588 * NEWS, doc/autoconf.texi (Particular Functions),
10589 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
10590 is the inverse of localtime.
10592 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
10594 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
10595 (handle_exec_errors): New function. Work around $! being
10596 altered by WEXITSTATUS.
10597 (xqx, xsystem): Use handle_exec_errors.
10599 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
10601 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
10602 Do not call `_exit()', simply modify `$?'.
10603 (xsystem): Reset $! before running system, and check it afterward.
10604 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
10605 63 for version mismatches.
10607 2003-05-23 Akim Demaille <akim@epita.fr>
10609 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10610 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10611 the middle of a line).
10612 * lib/m4sugar/m4sugar.m4: Likewise.
10613 Remove useless spaces in comments.
10615 2003-05-23 Akim Demaille <akim@epita.fr>
10617 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
10618 exit 63, so that we (or Automake's "missing") can tell the
10619 difference with a plain failure.
10620 * doc/autoconf.texi (Notices): Adjust.
10622 2003-05-23 Akim Demaille <akim@epita.fr>
10624 * Makefile.am, bin/Makefile.am, config/Makefile.am,
10625 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
10626 White spaces cleanup.
10628 2003-05-22 Jim Meyering <jim@meyering.net>
10629 Paul Eggert <eggert@twinsun.com>
10631 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10632 Remove `#include <stdlib.h>' from the list; we should never
10633 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10634 resulting namespace pollution would cause other tests to fail.
10635 Configure scripts run with some older versions of g++ and HP's
10636 aCC would fail due to such an #include. Problems reported by
10637 Matthew Mueller in <http://bugs.debian.org/120704> and by
10638 Keith Bostic in
10639 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10640 In the test, use the test declaration before including <stdlib.h>,
10641 as that's closer to how it'll be used.
10643 2003-05-23 Akim Demaille <akim@epita.fr>
10645 * doc/autoconf.texi (Header Portability): ucred.h.
10646 From Ian Redfern.
10648 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10650 Overhaul Autotest's logging: generate separate log files
10651 in testsuite.dir/NNN/testsuite.log, and append them to
10652 testsuite.log instead of re-running the test verbosely.
10654 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10655 file descriptor, write 0 to at_status_file instead of setting
10656 at_status=0, initialize some new variables (at_status_file,
10657 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10658 to rerun the tests, instead append the at_group_log to the
10659 at_suite_log when a test fails.
10660 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10661 with the AS_MESSAGE_LOG_FD redirected to stdout.
10662 (AT_CLEANUP): save the output status in $at_status_file
10663 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10664 its original place.
10665 (AT_CHECK): since tests are run with a redirected stdout,
10666 and used to be re-run in verbose mode, turn some $at_verbose
10667 into echo, and don't redirect the output of testing stdout
10668 and stderr.
10670 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10671 the name of the debugging directory and information about
10672 its contents.
10674 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10676 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
10677 parameter.

10700 Suggested by Jim Meyering.
10702 2003-05-22 Akim Demaille <akim@epita.fr>
10704 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
10705 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
10706 Reported by Jim Meyering.
10708 2003-05-22 Akim Demaille <akim@epita.fr>
10710 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

10743 2003-05-17 Akim Demaille <akim@epita.fr>
10745 * lib/autoconf/functions.m4: Use the default includes so that
10746 memcmp be declared before being tested.
10747 Reported by Sander Niemeijer.
10748 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.

10766 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10767 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
10768 them uniform, and more robust to Perl special characters.
10769 Reported by Martin Mokrejs.
10771 2003-05-14 Akim Demaille <akim@epita.fr>

10791 2003-05-06 Akim Demaille <akim@epita.fr>
10793 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10794 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10795 by aclocal.m4 is changed it might require the importing of another
10796 m4 extension file, i.e., aclocal must be run.
10798 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
10799 (&parse_args): Use --force with aclocal if required and supported.
10800 (&autoreconf_current_directory): Use &run_aclocal.

10808 argument instead of a file name, so that the request file remains
10809 open during the whole autom4te run.
10810 ($icache_file): New.
10811 (&freeze): Lock the $icache_file.
10813 2003-04-29 Derek Price <derek@ximbiot.com>
10815 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
10816 seperator with m4_append_uniq(). It doesn't work.
10817 (AT_CLEANUP): Add `;' to end of at_help_all.
10818 (AT_INIT): Allow --keywords to be specified more than once. When
10819 grepping $at_help_all for keywords, use the field and keyword
10820 seperators to ensure a complete keyword match. Alter at_prev handling
10821 to support the new --keywords behavior.
10823 2003-04-27 Karl Berry <karl@freefriends.org>
10825 * doc/autoconf.texi: Make the dir entries in the autoconf manual
10826 align better with others. I also made some of the individual
10827 entries on one line, for brevity and to make it easier for me to
10828 sort my dir-example file in the Texinfo distribution :).
10830 2003-04-12 Jim Meyering <jim@meyering.net>

10871 (TEXI2DVI): Make it --batch.
10873 2003-03-31 Derek Price <derek@ximbiot.com>
10875 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
10876 which removed the main loop.
10877 Thanks to Akim Demaille.

10895 header causes problems.
10897 2003-03-28 Akim Demaille <akim@epita.fr>
10899 * tests/torture.at (Configuring subdirectories): Require aclocal
10900 1.4, otherwise the test fails, as it does support configure.ac.

10970 * doc/autoconf.texi (Limitations of Make): Remove the section
10971 about `$<' in inference rules, it was a bogus interpretation of
10972 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
10973 Tru64 make in the "target lookup" section.
10974 (Automake): Automake 1.5+ no longer requires special tools to be
10975 present on the developer's host.
10977 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>

11025 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
11026 is not portable inside Makefile.
11028 2003-02-20 Akim Demaille <akim@epita.fr>
11030 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
11031 compiler says yeah, but preproc says nope, compiler is right.
11032 Conversely, prompt the reader to send a bug report to the
11033 maintainers of the package, not of Autoconf.
11035 2003-02-20 Klee Dienes <kdienes@apple.com>
11037 * bin/autoreconf.in (autoreconf_current_directory): Properly
11038 handle an empty aclocal.m4.

11044 From Larry Jones.
11046 2002-12-23 Paul Eggert <eggert@twinsun.com>
11048 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11049 innocuous variant befor including <limits.h> or <assert.h>. This
11050 works around a bug reported by Albert Chin: HP-UX 11i
11051 (and earlier versions) have a <limits.h> that declares
11052 gettimeofday and many other functions.
11054 2002-12-03 Paul Eggert <eggert@twinsun.com>
11056 Version 2.57.
11058 * NEWS, configure.ac: Update version.
11060 * doc/fdl.texi: Upgrade to FDL version 1.2.
11062 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
11063 nontrivially in main's body, so that f's external declaration is
11064 not optimized away in AIX. This should fix the bug reported by
11065 Martin Frydl in
11066 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11068 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11069 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11070 defined, to support freestanding compilers. This should fix the
11071 bug reported by Momchil Velkov in
11072 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11074 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11075 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
11076 obsolete AC_CHECK_TYPE. The missing empty arg was reported
11077 by Simon Josefsson in
11078 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
11080 * Makefile.maint (www-gnu): New macro.
11081 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
11082 the location has moved.
11084 2002-12-02 Martin Frydl <martin@systinet.com>
11086 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
11087 \(.*\) match is too long and there is something more to be checked.
11088 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
11090 2002-11-15 Akim Demaille <akim@epita.fr>
11092 Version 2.56.
11094 * config/install-sh: chmod +x.
11095 From Paul Eggert.
11096 * config/move-if-change: Indenting changes.
11097 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
11098 * configure.ac (AM_INIT_AUTOMAKE): here.
11099 Require 1.7.1.
11101 2002-11-14 Akim Demaille <akim@epita.fr>
11103 Version 2.55.
11105 * config/config.guess, config/config.sub, config/install-sh:
11106 Update from masters.
11108 2002-11-14 Akim Demaille <akim@epita.fr>
11110 * Makefile.maint: Sync with Bison, i.e.:
11111 (po-check): Scan .l and .y files instead of the
11112 .c and the .h files that they generate. This fixes the bug
11113 reported by Tim Van Holder in:
11114 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11115 Look for N_ as well as for _. Try to avoid matching #define for
11116 N_ and _.
11117 From Paul Eggert.
11119 2002-11-14 Akim Demaille <akim@epita.fr>
11121 * doc/autoconf.texi (C Compiler): Compiling several files at once.
11122 From Paul Eggert and Albert Chin-A-Young.
11124 2002-11-14 Akim Demaille <akim@epita.fr>
11126 * doc/autoconf.texi (C Compiler): Solitary backslashes.
11127 From Paul Eggert and Albert Chin-A-Young.
11129 2002-11-14 Kevin Ryde <user42@zip.com.au>
11131 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11132 than assigning in main, to avoid HP cc +O3 optimizing it away.
11134 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
11136 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11137 option. Process --recheck after parsing all options. Pass -q
11138 option to configure on --recheck.
11139 (AC_OUTPUT): Pass -q from configure to config.status.
11140 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
11141 arguments to record.
11142 * doc/autoconf.texi (config.status Invocation): Document
11143 config.status -q option.
11145 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11147 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11148 Makefile.in if Makefile.am exists.
11149 (output): Strip `.am' from Makefiles. Don't
11150 output AC_CONFIG_FILES if no Makefiles were found.
11152 2002-11-07 Akim Demaille <akim@epita.fr>

11161 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
11162 declaration in extern "C" too.
11163 Reported by Roberto Bagnara.
11165 2002-11-06 Akim Demaille <akim@epita.fr>
11167 * tests/torture.at (Configuring subdirectories): Don't use grep
11168 -w.
11169 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
11170 Reported by Ezra Peisach.
11172 2002-11-05 Akim Demaille <akim@epita.fr>
11174 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11175 Remove.
11176 We _have_ to stop using the old compatibility scheme that tried to
11177 avoid useless backslashes because Libtool 1.4.3 contains a
11178 AC_DEFINE([error_t], [int],
11179 [Define to a type to use for \`error_t' if it is not
11180 otherwise available.])
11181 We _have_ to quote the single quote and backslashes with \. The
11182 old compatibility scheme saw that ` was backslashed, and therefore
11183 did not quote the single quote. Hence before this patch, Autoconf
11184 was not compatible with Libtool.
11186 2002-11-04 Paul Eggert <eggert@twinsun.com>
11188 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
11189 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
11190 LC_NAME, LC_PAPER, LC_TELEPHONE.

11193 2002-11-04 Akim Demaille <akim@epita.fr>
11195 Version 2.54c.
11197 * Makefile.maint (update, cvs-update, po-update, do-po-update):
11198 New.
11199 * config/texinfo.tex: Update.
11201 2002-11-03 Akim Demaille <akim@epita.fr>

11204 from...

11207 Support -m/--make.

11223 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
11224 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
11226 2002-10-31 Akim Demaille <akim@epita.fr>
11228 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
11229 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
11230 Make variable, not a shell variable.
11231 Suggested by Bruno Haible.
11233 2002-10-31 Akim Demaille <akim@epita.fr>
11235 * bin/autom4te.in (load_configuration): Reject #args out of any
11236 language.

11254 2002-10-29 Paul Eggert <eggert@twinsun.com>
11256 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
11257 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
11258 Problem reported by Bruno Haible.
11260 2002-10-29 Akim Demaille <akim@epita.fr>
11262 * doc/autoconf.texi (Header Templates): Put also in words what the
11263 pictures says to assist free style readers.

11513 * doc/autoconf.texi (Limitations of Usual Tools): Remove incorrect
11514 words about HP-UX cmp: it was actually a user-written cmp.
11516 2002-10-22 Akim Demaille <akim@epita.fr>
11518 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
11519 are a few warnings.
11520 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
11521 Quote for Perl '' strings, not "".
11522 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
11523 strings.
11525 2002-10-22 Akim Demaille <akim@epita.fr>
11527 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
11528 characters is a syntax warning now.
11529 (_AS_QUOTE): Accept $2 as list of characters to quote.
11530 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
11531 Quote for Perl, not sh.
11532 * bin/autoheader.in: When $debug, report the file which is
11533 `do'ne.
11534 * tests/tools.at (autom4te, autoheader): Exercise @bar, not merely
11535 `@', to tickle Perl's lists.
11536 Reported by Carlos Velasco.
11538 2002-10-18 Akim Demaille <akim@epita.fr>
11540 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that
11541 missing included files _are_ errors.
11542 Thanks to Alexandre Duret-Lutz.
11543 * tests/tools.at (autom4te cache): Adjust.
11544 * tests/atspecific.m4 (AT_CHECK_AUTOM4TE): New.

11555 * lib/freeze.mk (check-forbidden-patterns): New.
11556 * lib/autoconf/Makefile.am, lib/autotest/Makefile.am
11557 * lib/m4sugar/Makefile.am (check-local): Use it to catch `cmp'.
11558 * doc/autoconf.texi (Limitations of Usual Tools): HP-UX' cmp and
11559 /dev/null.
11560 Reported months ago by H. Merijn Brand.
11562 2002-10-17 Akim Demaille <akim@epita.fr>

11566 2002-10-16 Paul Eggert <eggert@twinsun.com>

11569 (ansi2knr.c-url_prefix): Remove.
11571 2002-10-16 Akim Demaille <akim@epita.fr>
11573 Because of caching, some files that no longer exist and are no
11574 longer required can still cause errors.
11575 Reported by Alexandre Duret-Lutz.
11577 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
11578 to frozen files in @ARGV, as @ARGV must remain being a list of
11579 files. Rather, at M4 call sites, use this...
11580 (&files_to_options): New function.
11581 (&freeze): Use &error.
11582 (&up_to_date): If a file that was included according to the cache
11583 is no longer there, then the output is out dated.
11584 (&main): Don't even check whether a file is up to date is anyway
11585 --force is given.
11586 * tests/tools.at (autom4te cache): New.
11588 2002-10-16 Akim Demaille <akim@epita.fr>
11590 * bin/autoconf.as: Kill dead options.
11591 * bin/autoupdate.in (&parse_args): Kill old options.
11592 * bin/autoreconf.in (&parse_args): Remove dead options.
11593 Factor some code.
11594 (&autoreconf): Report the directories we enter *and leave*, so
11595 that error messages can be easily located, and use GNU Make
11596 format, so that Emacs' compile mode understands us.
11597 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
11598 if some file was changed instead of `print'.
11599 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
11600 (&parse_args): Remove the dead options.
11601 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
11602 autoheader's quiet mode.

11607 2002-10-11 Akim Demaille <akim@epita.fr>
11609 No longer use CPP to check for the existing of headers: use CC to
11610 check for compilability.
11612 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
11613 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

11615 (AC_CHECK_HEADER): this.
11617 * lib/autotest/general.m4 (AT_INIT): Include the failed test
11618 numbers in the Subject suggestion.
11620 2002-10-11 Akim Demaille <akim@epita.fr>
11622 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.

11625 2002-10-11 Akim Demaille <akim@epita.fr>
11627 * tests/torture.at (AC_ARG_VAR): Have configure report the value
11628 of `precious'.
11630 2002-10-11 Akim Demaille <akim@epita.fr>
11632 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
11633 file name to enable parallel executions.
11634 From Sam Varshavchik.
11636 2002-10-08 Akim Demaille <akim@epita.fr>
11638 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11639 aclocal invocation, as Gettext macros might not be visible to
11640 aclocal.
11641 Instead of blindly running autopoint, scan configure.ac (not the
11642 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11643 Reported by Paul D. Smith.
11645 2002-10-08 Paul Eggert <eggert@twinsun.com>
11647 Work around problems found when POSIXLY_CORRECT=1 is set.
11648 None of this seems to have anything to do with POSIX, really,
11649 but it's how Perl getopt works.
11650 * bin/autom4te.in (parse_args): Configure GetOpt with
11651 "permute", too.
11652 * doc/autoconf.texi (Invoking autom4te):
11653 --warning -> --warnings.
11654 * lib/autom4te.in: --warning -> --warnings.
11656 2002-09-28 Akim Demaille <akim@epita.fr>
11658 * doc/autoconf.texi (autom4te.cache): New section.

11673 2002-09-28 Akim Demaille <akim@epita.fr>
11675 * tests/torture.at (Configuring subdirectories): Be robust to
11676 users who use config.site to require for a cache: in this case,
11677 the two last configure runs, using two different sets of
11678 arguments, trigger a legitimate error.
11680 2002-09-28 Akim Demaille <akim@epita.fr>
11682 * tests/m4sh.at (Functions Support, Functions and return Support):
11683 New.

11690 (autom4te): Specify that the sources are in the $srcdir.
11691 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11693 2002-09-28 Akim Demaille <akim@epita.fr>
11695 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
11696 (tm_zone): Move their rules to...
11697 * lib/autoconf/types.m4: here, using AN_ macros.
11698 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
11699 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
11700 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

11704 Use it.

11708 * lib/autoconf/autoscan.m4: New file.
11709 * lib/autoconf/autoconf.m4: Include it.
11710 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
11711 that were listed in the original autoscan.list.
11712 * lib/autoconf/headers.m4: Similarly with headers.
11713 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
11714 (.m4.m4f): Don't pass --prepend-include, since that's done by
11715 tests/autom4te itself.
11716 * lib/autoscan/Makefile.am: Include freeze.mk.
11717 (autoscan.list): New target --this file is no longer a source.
11718 (autoscan.pre): New file.
11720 2002-09-28 Akim Demaille <akim@epita.fr>
11722 * bin/autoscan.in (@kinds): Make them singular.
11723 Adjust all uses.
11724 (&init_tables): When --debug, report the list of rules to ease
11725 tracking changes in autoscan.list.
11726 * lib/autoscan/autoscan.list (function): Strip comments, sort.
11728 2002-09-28 Akim Demaille <akim@epita.fr>
11730 * lib/autoscan/functions, lib/autoscan/headers,
11731 * lib/autoscan/identifiers, lib/autoscan/makevars,
11732 * lib/autoscan/programs: Merge into...
11733 * lib/autoscan/autoscan.list: this.
11734 * bin/autoscan.in (&init_tables): Adjust.
11736 2002-09-28 Akim Demaille <akim@epita.fr>
11738 * lib/autoscan/functions, lib/autoscan/headers,
11739 * lib/autoscan/identifiers, lib/autoscan/makevars,
11740 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
11741 `functions' line is now prefixed with `function:'.
11742 * bin/autoscan.in (&init_tables): Adjust.
11744 2002-09-28 Akim Demaille <akim@epita.fr>
11746 From now on, autoscan files must always map a macro name to a
11747 word: there is no `default' macro for autoscan.
11749 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11750 all.
11751 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
11752 explicit.
11754 2002-09-28 Akim Demaille <akim@epita.fr>
11756 * bin/autoscan.in (%c_keywords): Remove.
11757 (&used): Keep only track of the words we might be interested in.
11758 (&output_kind): It is no longer needed to look for non active
11759 checks.

11784 (getwd): Trigger a warning.
11786 2002-09-26 Akim Demaille <akim@epita.fr>
11788 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
11789 Reported by Ralf Corsepius.
11790 * doc/autoconf.texi (autoreconf Invocation): Likewise.
11792 2002-09-26 Akim Demaille <akim@epita.fr>
11794 Single suffix rules and seperated dependencies are not portable.

11798 Separated Dependencies'.
11799 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11800 (ifnames, autoscan, autom4te): Un-factor into several rules.
11802 2002-09-25 Paul Eggert <eggert@twinsun.com>
11804 * BUGS (Interoperability bugs): New section. Mention libtool

11841 reading config.log when the compiler is rejected.
11842 Suggested by Guido Draheim.
11844 2002-09-13 Akim Demaille <akim@epita.fr>
11846 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
11847 (chdir_init) might hang when stat'ing mounted directories.
11848 Reported by Vance Shipley.
11850 2002-09-12 Akim Demaille <akim@epita.fr>
11852 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
11853 the lists.
11855 2002-09-12 Akim Demaille <akim@epita.fr>
11857 * doc/autoconf.texi (Defining Symbols): Present two different
11858 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the

11863 * doc/autoconf.texi: Review grammar and punctuation.

11868 grammatical typos.
11869 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
11870 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
11871 is obsolescent.
11873 2002-09-11 Akim Demaille <akim@epita.fr>
11875 * doc/autoconf.texi (Questions): Rename as...
11876 (FAQ): this.

11887 plain `@' is wanted.
11889 2002-09-09 Akim Demaille <akim@epita.fr>
11891 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
11892 `duplicates', since the algorithm was too naive and could keep
11893 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
11894 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
11895 Reported by Ralf Corsepius.
11896 * tests/torture.at (Configuring subdirectories): Exercise these
11897 cases.
11899 2002-09-09 Akim Demaille <akim@epita.fr>
11901 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when

11917 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11918 (ifnames, autoscan, autom4te): Since we don't only depend on
11919 configure.ac variables (such as VERSION etc.), but also on prefix
11920 and so forth, depend on Makefile, not configure.ac.
11921 Reported by Alexandre Duret-Lutz.
11922 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11924 2002-09-05 Kevin Ryde <user42@zip.com.au>
11926 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
11927 doesn't seem to be confined to ia64, just say "some versions".
11929 2002-09-04 Akim Demaille <akim@epita.fr>
11931 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
11932 Automake 1.6c.
11933 * Makefile.am (maintainer-clean-local): Remove.
11934 (MAINTAINERCLEANFILES): Remove COPYING.

11944 * configure.ac: Bump to 2.53d.
11945 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11946 as of today, on Automake's team suggestion.
11948 2002-09-03 Akim Demaille <akim@epita.fr>
11950 Version 2.53c.
11952 2002-09-02 Akim Demaille <akim@epita.fr>
11954 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and

11960 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11961 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11962 Also, tweak grammar: s/make sure to/be sure to/.
11964 2002-09-02 Paul Eggert <eggert@twinsun.com>
11966 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11967 directory names are generally preferable to physical names.
11969 2002-09-02 Akim Demaille <akim@epita.fr>
11971 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11972 Reported by Raja R. Harinath.
11973 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11974 * bin/autoupdate.in: Use error instead of die.
11976 2002-09-01 Paul Eggert <eggert@twinsun.com>
11978 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11979 ordinary shell concatenation rather than echo+tr+sed command that
11980 runs afoul of a long-line-related sed bug in Solaris 8.
11982 * bin/autoheader.in (parse_args): --warning -> --warnings.
11984 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11985 stdout, as traditional "ls" does.
11986 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11987 _AC_COMPILER_EXEEXT_O): Likewise.
11988 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11990 * bin/autoconf.as: Add --prepend-include option. This patch was
11991 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11992 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11994 * bin/autoconf.in, configure: Regenerate.
11996 * doc/autoconf.texi (Special Shell Variables): Mention
11997 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11999 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12000 MAILPATH and set PS1, PS2, PS4 to default values, to work
12001 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12002 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12003 the Autoconf documentation specifies; fall back to "unset" only if
12004 this fails. Use a shell for-loop for this rather than an m4 loop,
12005 to shorten the output script.
12007 2002-08-30 Paul Eggert <eggert@twinsun.com>
12009 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12010 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12011 for the CDPATH problem. Document PWD.
12012 (Limitations of Builtins): Document the problem that "cd $foo" and
12013 "ls $foo" may refer to different directories in shells conforming
12014 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12015 example, since the old example is now out of date.
12017 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12018 FOO" and "ls FOO" talk about different directories; this catches
12019 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12020 spaghetti.
12022 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12023 of rolling our own unset.
12024 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12025 in practice we needn't worry about CDPATH if unset doesn't work.
12027 * Makefile.in, aclocal.m4, bin/Makefile.in,
12028 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12029 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12030 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12031 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12032 tests/Makefile.in: Regenerate with Automake 1.6.3.
12034 * config/config.guess, config/config.sub, config/mkinstalldirs:
12035 Update.
12037 * configure: Regenerate with self.
12039 2002-08-30 Kevin Ryde <user42@zip.com.au>
12041 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12042 default output.
12044 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12046 * bin/autom4te.in (Request::load): Correctly test for "do" read
12047 failure.
12049 2002-08-29 Akim Demaille <akim@epita.fr>
12051 * lib/Autom4te/General.pm (&xqx): New.
12052 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12053 hand, which is not portable.
12054 (&error): New.
12055 * bin/autom4te.in: Use them.
12056 Use &error instead of die.
12057 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12058 Adjust.
12060 2002-08-17 Paul Eggert <eggert@twinsun.com>
12062 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12063 default list of compilers to try, since it was long ago superseded
12064 by the ksh fc builtin. Suggested by Steven G. Johnson.
12066 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12068 * doc/autoconf.texi (Invoking autom4te): End the option table,
12069 fixing a bug introduced by the previous patch.
12070 (Limitations of Make): Add a 'target lookup' subentry in the
12071 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12073 2002-07-29 Mark D. Roth <roth@feep.net>
12075 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12076 options and use $AUTOM4TE_PATH.
12077 * doc/autoconf.texi: Remove documentation of autom4te
12078 --include-envvar and --site-macro-subdir options and document
12079 use of $AUTOM4TE_PATH.
12080 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12081 arguments from each language section.
12083 2002-07-29 Paul Eggert <eggert@twinsun.com>
12085 * doc/install.texi: Include copyright symbol in copyright notice.
12087 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12088 Replace with:
12089 (AM_MAKEINFOFLAGS): New macro.
12090 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12091 * Makefile.am (INSTALL): Use the new macros.
12092 Use -o rather than --output, since "missing" does not grok --output.
12094 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12096 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12097 comments do not always work. Never trust the exit status of
12098 `make -k'.
12100 2002-07-24 Kevin Ryde <user42@zip.com.au>
12102 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12103 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12105 2002-07-23 Paul Eggert <eggert@twinsun.com>
12107 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12108 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12109 apparently treats PATH="nonexistent" as if it contained ".".
12110 Bug reported by Stefan `Sec' Zehl.
12112 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12114 * doc/autoconf.texi (Limitations of Make): Mention the special
12115 handling of the obj/ directory by BSD make.
12117 2002-07-20 Kevin Ryde <user42@zip.com.au>

12125 (Programming in M4sh): Ethymology of M4sh.
12127 2002-07-19 Akim Demaille <akim@epita.fr>
12129 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
12131 2002-07-18 Akim Demaille <akim@epita.fr>
12133 Version 2.53b.
12135 2002-07-18 Akim Demaille <akim@epita.fr>
12137 * config/config.guess, config/config.sub: Update.
12139 2002-07-18 Akim Demaille <akim@epita.fr>
12141 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
12142 Automake's parts.

12161 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
12162 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
12163 latter was not run.

12167 * lib/Autom4te/General.pm (find_file): Browse the directories in
12168 the order they are given.

12190 * lib/autom4te.in: Use --prepend-include instead of --include.
12191 * tests/wrapsh.in: Use --prepend-include instead of --include.
12193 2002-07-17 Akim Demaille <akim@epita.fr>

12229 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
12231 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
12232 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
12233 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
12234 so that Emacs setups GNU style for perl-mode and cperl-mode.
12236 2002-06-27 Paul Eggert <eggert@twinsun.com>
12238 * config/install-sh: Quote $src. Prefer || to test's -o option,
12239 as per "Limitations of Builtins".
12240 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
12241 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
12243 * tests/mktests.sh: Use grep instead of fgrep, as per
12244 "Limitations of Builtins".
12246 2002-06-15 Paul Eggert <eggert@twinsun.com>
12248 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
12249 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
12250 so that we consistently test the just-built programs.
12251 * tests/wrappl.as: Likewise.
12253 2002-06-12 Paul Eggert <eggert@twinsun.com>
12255 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
12256 name, so that symlinks to 'autoconf' work properly. Bug reported
12257 by Bruno Haible.
12258 * bin/autoheader.in (AUTOM4TE): Likewise.
12259 * bin/autoreconf.in (autoconf, autoheader): Likewise.
12260 * bin/autoscan.in (autom4te): Likewise.
12261 * bin/autoupdate.in (autom4te): Likewise.
12263 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
12264 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
12265 on Solaris 2.5.1.
12267 2002-06-11 Andreas Schwab <schwab@suse.de>
12269 * doc/autoconf.texi: Add more dir entries.
12271 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
12273 * bin/autom4te.in ($cache): Don't define using `$me', the name
12274 of the cache should not depend on the name under which autom4te
12275 was installed.
12277 2002-06-07 Akim Demaille <akim@epita.fr>
12279 * tests/tools.at (autoconf: forbidden tokens, basic)
12280 (autoconf: forbidden tokens, exceptions): Adjust to the change of
12281 words in autom4te.in.
12283 2002-06-07 Peter Eisentraut <peter_e@gmx.net>

12288 2002-06-07 Akim Demaille <akim@epita.fr>
12290 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
12291 rename as...
12292 (AC_REPLACE_FNMATCH): this.
12293 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
12294 AC_FUNC_FNMATCH_GNU.
12296 2002-06-07 Akim Demaille <akim@epita.fr>
12298 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
12299 Rosetta Stone for Unix.
12301 2002-06-07 Akim Demaille <akim@epita.fr>
12303 * bin/autom4te.in (warn_forbidden): When rejecting a token,
12304 suggest m4_pattern_allow.
12305 Suggested by Adam J. Richter.
12307 2002-06-07 Akim Demaille <akim@epita.fr>
12309 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
12310 ac_config_libobj_dir.
12311 (AC_CONFIG_LIBOBJ_DIR): New.
12312 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
12313 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
12314 Use ac_config_libobj_dir to find the replacement files.
12315 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
12316 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
12317 (AC_REPLACE_FNMATCH_GNU): these.
12318 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
12319 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
12320 * tests/mktests.sh (ac_exclude_list): Don't check
12321 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
12323 2002-06-06 Paul Eggert <eggert@twinsun.com>
12325 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
12326 if ln doesn't work.
12327 * NEWS: Likewise.
12328 * doc/autoconf.texi (Configuration Links): Likewise.
12329 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
12331 2002-06-05 Paul Eggert <eggert@twinsun.com>
12333 * config/config.guess, config/config.sub, config/texinfo.tex:
12334 Update from masters.
12336 2002-05-29 Paul Eggert <eggert@twinsun.com>
12338 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.

12351 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
12352 * doc/autoconf.texi (Particular Programs): Document them.
12353 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
12354 * NEWS: Likewise.
12356 2002-05-27 Paul Eggert <eggert@twinsun.com>
12358 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
12359 * NEWS, doc/autoconf.texi (Particular Types): Document it.
12360 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
12361 instead of AC_MBSTATE_T, which never existed.
12363 2002-05-23 Akim Demaille <akim@epita.fr>
12365 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
12366 version of Autoconf that is discussed.
12368 2002-05-22 Paul Eggert <eggert@twinsun.com>
12370 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
12371 from the default list of compilers to try. Suggested by
12372 Kate Hedstrom.
12373 * NEWS: Document the above.
12374 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
12376 2002-05-17 Paul Eggert <eggert@twinsun.com>
12378 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
12379 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
12380 This improves on an earlier suggestion by H. Peter Anvin.
12382 2002-05-16 Paul Eggert <eggert@twinsun.com>
12384 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12385 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12386 Both macros now accept an optional source-dir arg.
12387 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12389 * NEWS: Document this.
12390 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12392 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12393 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12394 not for GNU extensions; this undoes part of the 2000-11-03 change,
12395 reverting to 2.13-compatible behavior.
12396 Add new optional argument DIR.
12397 (AC_FUNC_FNMATCH_GNU): New macro.
12399 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
12401 2002-05-08 Paul Eggert <eggert@twinsun.com>
12403 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12404 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12405 and it causes a 'test' syntax error if it fails.
12406 Bug reported by Stephen Gildea.
12408 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12409 If prototypes are supported, use them to check this at compile-time,
12410 instead of trying to check it at run-time. If we must do a run-time
12411 check, assume that setvbuf is standard when cross-compiling, as
12412 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12413 Bug reported by Paul D. Smith.
12415 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12416 argument specifying location of getloadavg.c. This removes a
12417 FIXME. This idea was taken from Jim Meyering's implementation in
12418 textutils.
12419 * doc/autoconf.texi (Particular Functions): Document this.
12420 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12421 that's what the code does; this fixes a bug reported by
12422 Paul D. Smith.
12424 2002-05-03 Akim Demaille <akim@epita.fr>
12426 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12427 autopoint instead of gettextize.
12428 ($uses_alocal): Rename as...
12429 ($uses_aclocal): this.
12430 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12431 Suggested by Bruno Haible.
12433 2002-05-03 Akim Demaille <akim@epita.fr>
12435 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12437 2002-04-29 Paul Eggert <eggert@twinsun.com>
12439 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12440 files to be 1 second older; just set them to be the same time.
12441 Also, sleep 1 second after the first aclocal, to work around
12442 problems with sub-second time stamps on the input files.
12444 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12446 * doc/autoconf.texi: Mention "set -e -x" lossage
12447 under node "Limitations of Builtins".
12449 2002-04-29 Akim Demaille <akim@epita.fr>
12451 * doc/install.texi: Better wording for setting variables when
12452 running configure.
12453 From Christian Cornelssen.
12455 2002-04-29 Akim Demaille <akim@epita.fr>
12457 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12458 of lack of $LINENO support, then the test will compare the $LINENO
12459 in testsuite vs. the lineno in the test file. This is wrong, of
12460 course.
12461 Be sure to protect it.
12462 Reported by Patrick Welche.
12464 2002-04-25 Akim Demaille <akim@epita.fr>
12466 * doc/autoconf.texi (Obsolete Macros): Typo.
12467 Reported by Vladimir Volovich.
12469 2002-04-25 Akim Demaille <akim@epita.fr>
12471 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12472 than some of the input files, hence, on the second run of aclocal,
12473 if some of its input are younger, make them older.
12474 Suggested by Paul Eggert.
12476 2002-04-25 Akim Demaille <akim@epita.fr>
12478 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
12479 Thanks to Paul Eggert.
12481 2002-04-25 Akim Demaille <akim@epita.fr>
12483 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
12484 and ac_subst_vars be sh variables containing the list of
12485 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12486 DEFAULT diversion.
12487 (_AC_INIT_PREPARE): Use them to log them.
12488 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12489 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12490 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12491 _AC_SUBST_FILES and _AC_SUBST_VARS.
12492 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12494 2002-04-24 Akim Demaille <akim@epita.fr>
12496 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12497 autoheader, so that automake does not complain about a missing
12498 config.h.in that was to be created.
12500 2002-04-23 Akim Demaille <akim@epita.fr>
12502 * bin/autoheader.in (parse_args): --warning takes an argument.
12503 Fixes PR/220.
12505 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
12507 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
12508 and bb.out when cleaning up.
12510 2002-04-22 Akim Demaille <akim@epita.fr>
12512 Version 2.53a.
12514 2002-04-22 Akim Demaille <akim@epita.fr>

12518 2002-04-22 Akim Demaille <akim@epita.fr>
12520 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
12521 comma.
12522 Reported by Gregory Giannoni.
12524 2002-04-22 Akim Demaille <akim@epita.fr>
12526 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
12527 Fixes false failures on Darwin.

12536 2002-04-20 Paul Eggert <eggert@twinsun.com>

12552 Minor spelling and grammar fixes.
12554 * doc/autoconf.texi: Follow the outline suggested in the GNU
12555 Sample Texts sections of the Texinfo 4.2 manual. Most
12556 importantly, this makes sure that the copyright notices appear in
12557 all output formats. You probably need Texinfo 4.2 to generate
12558 the manual now.
12560 Fix some bugs when using "$@" when there might be zero positional
12561 arguments in cases where this matters.

12582 that is not portable to Zsh.
12584 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
12586 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
12587 from aclocal.m4 too.
12589 2002-04-12 Akim Demaille <akim@epita.fr>

12593 2002-04-10 Akim Demaille <akim@epita.fr>
12595 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
12596 workaround for ${1+"$@"}.
12597 * doc/autoconf.texi (Shell Substitutions): Explain it.
12598 From Oliver Kiddle and Peter Stephenson.
12600 Have M4sh perform minimal shell sanitizing.
12602 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
12603 part into...
12604 (_AS_PREPARE): this new macro.
12605 (AS_PREPARE): New.
12606 (AS_INIT): Invoke AS_SHELL_SANITIZE.
12607 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
12609 Adjust Autoconf and Autotest.
12611 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12612 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
12613 * lib/autotest/general.m4 (AT_INIT): Likewise.
12614 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
12615 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
12616 AS_SHELL_SANITIZE.
12618 Use this M4sh to generate Autoconf's shell scripts.
12620 * tests/wrapsh.as: New, precursor of wrapsh.in.
12621 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
12622 on Autotest and M4sh.
12623 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
12624 (wrapsh.in): New target.
12625 * bin/autoconf.as: New, precursor of autoconf.in.
12626 (autoconf.in): New target.
12628 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
12630 * doc/autoconf.texi (Limitations of Make): Mention the issue
12631 with indented comments in rules.
12633 2002-04-09 Andreas Schwab <schwab@suse.de>
12635 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
12636 ac_top_builddir when setting ac_abs_top_builddir.
12638 2002-04-06 Kevin Ryde <user42@zip.com.au>
12640 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
12641 (Portable Shell): Cross reference to Systemology.
12643 2002-04-05 Akim Demaille <akim@epita.fr>
12645 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
12646 directories when descending in a SUBDIRS.
12647 Reported by Ezra Peisach.
12649 2002-04-04 Andreas Schwab <schwab@suse.de>
12651 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
12652 contains no literal separators.
12654 2002-04-03 Akim Demaille <akim@epita.fr>
12656 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
12657 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
12658 Use dnl, not the KILL diversion.
12659 Extracted from...
12660 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12661 (AC_CONFIG_LINKS): here.
12662 Adjust.
12663 Don't use the KILL diversion, as it kills spurious output, which
12664 results in failures being hidden.
12665 Use m4_defn where appropriate.
12666 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12667 after the second argument.
12668 Use m4_defn.
12669 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12670 syntax, as it is provided by M4sugar.
12671 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
12673 2002-04-03 Andreas Schwab <schwab@suse.de>
12675 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
12676 expanded if $# <= 2.
12678 * bin/autoreconf.in (autoreconf): Run automake after rerunning
12679 aclocal.
12681 2002-04-03 Akim Demaille <akim@epita.fr>

12686 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
12687 (_AC_COMPILER_OBJEXT): Use them.
12688 Fixes Debian #138666.
12690 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
12692 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
12694 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
12695 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
12696 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
12697 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
12698 (AC_C_CONST): Same.
12699 (AC_C_INLINE): Same.
12700 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
12701 * doc/autoconf.texi, NEWS: Document.
12702 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
12703 AC_C_CROSS.
12705 2002-04-02 Akim Demaille <akim@epita.fr>

12708 _AS_MKDIR_P_PREPARE.
12710 2002-03-28 Kevin Ryde <user42@zip.com.au>
12712 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12713 to avoid versions of HP C which don't allow that.
12715 2002-03-27 Paul Eggert <eggert@twinsun.com>
12717 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
12718 (AS_SHELL_SANITIZE): Invoke it.
12719 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
12721 2002-03-26 Akim Demaille <akim@epita.fr>
12723 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
12725 2002-03-26 Akim Demaille <akim@epita.fr>
12727 * doc/autoconf.texi (Introduction): The GNATS base moved.
12729 2002-03-25 Paul Eggert <eggert@twinsun.com>
12731 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12732 as POSIX requires, as it doesn't work with Zsh.
12733 * doc/autoconf.texi (Assignments): Document the problem.
12735 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12737 * doc/autoconf.texi (Limitations of Make): Mention more issue
12738 about VPATH, overriding of macros in sub-makes, and handling of
12739 SHELL.
12741 2002-03-21 Paul Eggert <eggert@twinsun.com>
12743 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12744 problem with here-document buffer boundaries.
12746 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12747 when reinvoking the shell, to work around problems with installers
12748 who put strange things like "cd" commands in their environments.
12750 2002-03-19 Akim Demaille <akim@epita.fr>
12752 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
12753 From Aaron Ucko.
12755 2002-03-19 Akim Demaille <akim@epita.fr>
12757 * bin/autoscan.in (scan_file): Specify the location in `&used'
12758 invocations.
12759 From Nicolas Joly.
12761 2002-03-19 Akim Demaille <akim@epita.fr>
12763 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
12764 From Nishio Futoshi.
12766 2002-03-19 Akim Demaille <akim@epita.fr>
12768 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
12770 2002-03-18 Paul Eggert <eggert@twinsun.com>
12772 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
12773 (Limitations of Usual Tools): Add mkdir section.
12775 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12776 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12777 back on AS_DIRNAME to compute prefixes otherwise; this is
12778 roughly what mkinstalldirs does. That way, we need not have
12779 our own filename disassembler. The old disassembler did not
12780 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12782 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12783 Create at_test_all by a series of assignments,
12784 not by a single assignment of a long string. The latter causes ksh
12785 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12786 presumably because of a buffer overrun.
12788 2002-03-14 Paul Eggert <eggert@twinsun.com>
12790 * lib/autotest/general.m4 (at_times_skip):
12791 Renamed from at_times. Now a boolean.
12792 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12793 says 'times: not found'.
12795 2002-03-14 Akim Demaille <akim@epita.fr>
12797 * bin/autoreconf.in (&study_gettextize): New.
12798 (&autoreconf): Handle newest gettextize.
12799 Rerun aclocal if needed.
12800 Suggested by Andreas Schwab.
12802 2002-03-13 Akim Demaille <akim@epita.fr>
12804 * doc/autoconf.texi (Special Shell Variables): More about IFS.
12806 2002-03-13 Akim Demaille <akim@epita.fr>
12808 * doc/autoconf.texi (Header Portability): New.
12809 Add information about stdint.h and inttypes.h from Paul Eggert.
12811 2002-03-13 Akim Demaille <akim@epita.fr>
12813 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
12814 -p'.
12815 From Bob Proulx.
12817 2002-03-12 Akim Demaille <akim@epita.fr>
12819 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
12820 m4_require.
12822 2002-03-11 Andreas Schwab <schwab@suse.de>
12824 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
12825 does not do it if --with-lispdir is given.
12827 2002-03-08 Akim Demaille <akim@epita.fr>
12829 Version 2.53.
12831 2002-03-08 Akim Demaille <akim@epita.fr>
12833 * doc/autoconf.texi (Subdirectories): Clarify that the
12834 subdirectory should exist.
12836 2002-03-08 Akim Demaille <akim@epita.fr>
12838 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
12840 2002-03-08 Akim Demaille <akim@epita.fr>
12842 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
12843 aliases the actual variables, and modifications of the former
12844 affect the latter.
12846 2002-03-08 Akim Demaille <akim@epita.fr>
12848 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
12849 because of C-c: have m4 output in tmp files, then mv them.
12851 2002-03-08 Akim Demaille <akim@epita.fr>
12853 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
12854 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
12855 * bin/ifnames.in: Copyright update.

12861 2002-03-05 Akim Demaille <akim@epita.fr>
12863 * doc/autoconf.texi (Specifying Names): Clarification suggested by
12864 Kevin Ryde.
12866 2002-03-05 Akim Demaille <akim@epita.fr>
12868 Version 2.52i.
12870 2002-03-04 Akim Demaille <akim@epita.fr>
12872 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
12873 * lib/autoconf/general.m4 (AC_INIT): More informative error
12874 message for LIBOBJ.
12876 2002-03-04 Akim Demaille <akim@epita.fr>
12878 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
12879 parallel builds.
12881 2002-03-04 Akim Demaille <akim@epita.fr>
12883 * doc/autoconf.texi (Transforming Names): Equality between target
12884 and host is irrelevant.
12885 (Specifying Names, Canonicalizing): Remove all references to the
12886 backward compatibility hooks. Rather, collect them all into...
12887 (Hosts and Cross-Compilation): this new section.
12888 * doc/install.texi (System Type): Ditto.
12889 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12890 that `--host' implies cross-compilation.
12892 2002-03-04 Akim Demaille <akim@epita.fr>
12894 * doc/autoconf.texi (Evaluation Macros): New.
12895 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
12896 useless.
12897 (_m4_foreach): Define the variant with immediate evaluation so
12898 that it contains exactly the items, not an expression which
12899 evaluation is the current item.
12900 (m4_re_string, m4_re_word): Don't over quote them.
12902 2002-03-04 Akim Demaille <akim@epita.fr>
12904 Instead of having stacking `shift's evaluated at the end, let
12905 `foreach' loops immediately evaluate them.
12907 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12908 $*. This is the n-th time I change my mind, but hopefully this is
12909 the last...
12910 (m4_lquote): New.
12911 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12912 efficient.
12913 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12914 it was only a hack for m4_text_wrap.
12915 (m4_car2): Remove, replaced by...
12916 (m4_cdr): New.
12917 (_m4_foreach): Adjust.
12918 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12919 m4_bpatsubst for clarification.
12921 2002-03-04 Akim Demaille <akim@epita.fr>
12923 * doc/autoconf.texi (Changequote is Evil): New.

12927 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
12928 on old systems like SunOS.

12950 From Akinori Musha.
12952 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
12954 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
12955 translate \r\n to \n.
12957 2002-02-07 Akim Demaille <akim@epita.fr>
12959 Version 2.52h.
12961 2002-02-07 Akim Demaille <akim@epita.fr>
12963 Fix Autoconf PR/209.
12964 Also reported by Frank Denis.

12968 2002-02-07 Akim Demaille <akim@epita.fr>
12970 Fix Autoconf PR/207:
12971 AC_PREFIX_PROGRAM fails with dashed program names
12973 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
12974 variable when looking for the prefix program.
12975 Now it also works for shell variables.
12977 2002-02-07 Akim Demaille <akim@epita.fr>
12979 * doc/autoconf.texi (Limitations of Builtins): More about
12980 case/esac.

12984 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
12985 case/esac, some shells don't support it.
12986 Reported by Zack Weinberg.
12987 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
12989 2002-02-06 Akim Demaille <akim@epita.fr>
12991 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
12992 sure not to introduce newlines in at_groups.
12993 * lib/autotest/Makefile.am (autotest.m4f): Typo.
12995 2002-02-06 Akim Demaille <akim@epita.fr>
12997 * tests/torture.at (Configuring subdirectories): Skip if aclocal
12998 is not available.
13000 2002-02-05 Paul Eggert <eggert@twinsun.com>
13002 * doc/autoconf.texi (Specific Compiler Characteristics):
13003 Describe HP-UX cc bug workaround more accurately.
13004 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
13005 not unsigned long.
13006 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
13007 cross-compilers, too. This undoes some of the most recent change
13008 to this file.
13010 2002-02-05 Akim Demaille <akim@epita.fr>
13012 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
13013 to make sure they are up to date when `check' is run.
13015 2002-02-05 Akim Demaille <akim@epita.fr>
13017 * doc/autoconf.texi (Making testsuite Scripts): Document
13018 package.m4.
13020 2002-02-05 Akim Demaille <akim@epita.fr>
13022 * lib/freeze.mk: New.
13024 2002-02-05 Akim Demaille <akim@epita.fr>
13026 Implement `autom4te --freeze'.
13028 * bin/autom4te.in (&freeze): New.
13029 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
13030 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
13032 2002-02-05 Akim Demaille <akim@epita.fr>
13034 * bin/autom4te.in (&parse_args): Implement `frozen files are
13035 optional are the sum of the previous files on the command line'.
13036 Also, pass `--reload-state=' on them, so...
13037 (handle_m4): don't.
13038 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13039 (M4sh): Rely on M4sugar.
13040 (Autotest, M4sh, M4sugar): Use frozen files.
13042 2002-01-31 Akim Demaille <akim@epita.fr>
13044 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
13045 * doc/autoconf.texi (Initializing configure): Adjust.
13047 2002-01-30 Akim Demaille <akim@epita.fr>
13049 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
13050 alphanumeric to `-' instead of `_'.
13052 2002-01-30 Akim Demaille <akim@epita.fr>
13054 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
13055 for plain code, the other for cross-compilation code. The latter
13056 is now run with GCC only.

13059 2002-01-30 Akim Demaille <akim@epita.fr>
13061 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
13062 values.

13074 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13075 needs an argument.
13077 2002-01-28 Akim Demaille <akim@epita.fr>
13079 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13080 AUTOTEST_PATH *after* it was set.
13081 Don't put `.' in the PATH: the user should be precise and `./' if
13082 needed. In addition, given that the test suite does some `cd', if
13083 `.' is in the path, the `tested programs' sections will report
13084 programs found in the test suite's directory, while during the
13085 tests (performed in their own directory), these programs are no
13086 longer visible. In other words, the results is confusing and
13087 useless.
13088 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
13090 2002-01-24 Akim Demaille <akim@epita.fr>

13101 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
13102 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
13103 Bourne. Use /bin/sh.
13104 From Andreas Buening.
13106 2002-01-24 Akim Demaille <akim@epita.fr>
13108 * config/config.guess, config/config.sub, config/texinfo.tex:

13118 Automake.
13120 2002-01-24 Akim Demaille <akim@epita.fr>
13122 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
13123 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
13124 Reported by Geir Ove Myhr.
13126 2002-01-21 Akim Demaille <akim@epita.fr>
13128 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
13130 2002-01-21 Akim Demaille <akim@epita.fr>
13132 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13133 message on invalid options.
13134 * bin/autom4te.in (parse_args): Don't use
13135 Autoconf::General::getopt with non valid options.
13137 2002-01-17 Jim Meyering <meyering@lucent.com>
13139 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13140 $ac_cv_exeext so we don't use an old, invalid, cached value.
13142 2002-01-11 Akim Demaille <akim@epita.fr>
13144 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
13145 Meyering.

13147 limitation.

13151 2002-01-06 Akim Demaille <akim@epita.fr>
13153 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13154 package.m4, since is really depends upon configure.ac, not
13155 configure.
13156 * doc/autoconf.texi (testsuite Scripts): Adjust.
13157 * tests/Makefile.am (package.m4): New.
13158 EXTRA_DIST it since its a source.
13160 2002-01-06 Akim Demaille <akim@epita.fr>
13162 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13163 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13164 and PACKAGE_BUGREPORT from here...
13165 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13166 arguments.
13167 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13168 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13169 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13170 * tests/tools.at (autoheader): Adjust.
13171 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
13173 2002-01-06 Akim Demaille <akim@epita.fr>

13185 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13186 sometimes needing writable input.
13188 2001-12-17 Jim Meyering <meyering@lucent.com>
13190 * doc/autoconf.texi (New Macros): Tweak wording.
13192 2001-12-14 Akim Demaille <akim@epita.fr>
13194 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13195 trailing files, don't apply `-rf' to files which might not be
13196 created by configure (core, core.*, and *.core), but just `rm -f'.
13197 Suggested by Jonathan Kamens.
13199 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13201 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13203 2001-12-14 Akim Demaille <akim@epita.fr>
13205 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13207 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

13210 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13211 abs_srcdir, top_srcpath to abs_top_srcdir.

13214 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13215 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13217 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13219 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13220 C/Fortran linking on HP/UX, by extracting the Fortran library
13221 search path from the LPATH line in the $F77 -v output.
13223 2001-12-12 Kevin Ryde <user42@zip.com.au>
13225 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13226 forbidden file descriptors table.
13228 2001-11-26 Akim Demaille <akim@epita.fr>
13230 * bin/autoscan.in (%c_keywords): Build it at top level.
13231 Map to 1 in order to simplify its uses.
13233 2001-11-26 Akim Demaille <akim@epita.fr>
13235 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13236 Remove $filepath, useless.
13237 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13238 variables, they are really part of the tokens.
13239 Split the input line on spaces and then look for tokens.
13240 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13241 because of `lex$U.$(OBJEXT)'.
13242 (&scan_files): Use "@list" instead of join.
13243 * doc/Makefile.am (CLEANFILES): Add *.fns.
13245 2001-11-26 Akim Demaille <akim@epita.fr>
13247 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13248 Remove, replaced by...
13249 * tests/wrappl.in: Be common for all the Perl executables.
13250 In particular autoscan and autoheader want -I.
13251 * configure.ac: Adjust.
13252 * lib/autoscan/headers: errno.h is portable.
13254 2001-11-26 Akim Demaille <akim@epita.fr>
13256 * bin/autoscan.in (used): New.
13257 Use it.
13259 2001-11-26 Akim Demaille <akim@epita.fr>
13261 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13262 directives.
13263 (&scan_sh_file): Remove a duplicate pattern.
13264 (&check_configure_ac): Use long options.

13270 Before, having a line containing the opening of a multi line
13271 comment made the whole line be ignored.
13273 2001-11-26 Akim Demaille <akim@epita.fr>
13275 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13276 (testsuite Scripts): Be one of its subsection.
13277 (Autotest Logs): New.
13279 2001-11-26 Akim Demaille <akim@epita.fr>
13281 Test groups are now run two directories deeper.
13283 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13284 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13285 at_top_builddir.
13286 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13287 top_srcdir, builddir and top_builddir.
13288 Use `at_*dir' relatively to the directory containing the
13289 suite, use `*dir' when relatively to the current group dir.
13291 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13293 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13294 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13295 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13296 spelling errors.
13298 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13300 * doc/autoconf.texi (Using System Type): Add an example of `case
13301 $host' usage so people quit using `case $target' everywhere.
13303 2001-11-22 Akim Demaille <akim@epita.fr>
13305 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13306 spotted by Jim Meyering.
13308 2001-11-16 Paul Eggert <eggert@twinsun.com>
13310 This patch implements a `long double' suggestion by Oliver Kiddle.
13312 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13313 static, to catch errors if the value isn't known at compile-time
13314 and the compiler supports dynamic arrays. Change its name from
13315 `_array_' to `test_array' to avoid potential name clashes.
13316 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13317 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13318 better than double. Catch a bug in GCC 2.95.2 x86.
13319 * doc/autoconf.texi (C Compiler): Document the above.
13320 * NEWS: Likewise.
13322 2001-11-13 Akim Demaille <akim@epita.fr>
13324 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13325 hand.
13326 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13328 2001-11-13 Akim Demaille <akim@epita.fr>
13330 * lib/autotest/general.m4 (AT_INIT): After having run the test
13331 group, go back to the initial directory, not to at_suite_dir.
13333 2001-11-13 Akim Demaille <akim@epita.fr>
13335 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13336 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13337 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13338 option.
13339 (AT_CHECK_CONFIGURE): Use absolute paths.
13340 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13341 The problem is still the old one: there is no means in M4 (that I
13342 know about) to create a defining macro, because there is no means
13343 to create `$1' etc., therefore, the defining macro ``swallows''
13344 all the arguments meant to the defined macro.
13346 2001-11-13 Akim Demaille <akim@epita.fr>
13348 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13349 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13350 configure.ac.
13351 * tests/aclocal.m4: Remove, as it is no longer used.
13353 2001-11-13 Akim Demaille <akim@epita.fr>
13355 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13356 variable names when referring to a single test group, or to
13357 `suite' when referring to the whole test suite.
13358 `at_last_test' is removed: m4 compute at_format itself.
13359 (at_stdout, at_stder1, at_stderr): New variables.
13360 (AT_CHECK): Use them.
13362 2001-11-13 Akim Demaille <akim@epita.fr>
13364 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13365 in PATH.
13366 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13367 Do it as soon as a test fails, don't wait till the end of the test
13368 suite.
13369 Don't remove $as_me.[0-9]*, since these files no longer exist.
13371 2001-11-13 Akim Demaille <akim@epita.fr>
13373 * tests/tools.at: Use absolute paths, since we are no longer run
13374 in place.
13376 2001-11-13 Akim Demaille <akim@epita.fr>
13378 Now that tests are running in their own private dir, there is no
13379 need to list the files to remove at the end of tests groups.
13381 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13382 (AT_data_files, at_data_files): Remove.
13383 (AT_CLEANUP, AT_DATA): Simplify.
13384 (AT_INIT): Adjust.
13385 Remove the group dir if !debug && !failed.
13386 * tests/atspecific.m4: Adjust.
13388 2001-11-13 Akim Demaille <akim@epita.fr>
13390 Start a new layout for Autotest: `testsuite' creates
13391 `testsuite.dir' in which the at-check-line etc. files are to be
13392 found, and `testsuite.dir/003' where the test group 3 is run.
13394 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13395 at_check_line_file, at_format, at_test_normalized, at_group_dir
13396 are new variables.
13397 Create the directories.
13398 Use absolute paths for at- files.
13399 (AT_CHECK): Adjust.
13401 2001-11-11 Michael Matz <matz@kde.org>
13403 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13404 (m4_car2): New.
13405 (m4_car): Properly quote arguments.
13407 2001-11-13 Akim Demaille <akim@epita.fr>
13409 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13410 with stricter rules on LIBOBJS.
13412 2001-11-12 Paul Eggert <eggert@twinsun.com>
13414 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13415 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13416 __PROTOTYPES too.
13418 2001-11-12 Akim Demaille <akim@epita.fr>
13420 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13422 2001-11-12 Akim Demaille <akim@epita.fr>
13424 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13425 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13426 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13427 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13428 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13429 specify to what the macro should be defined (typically to 1).
13431 2001-11-12 Akim Demaille <akim@epita.fr>
13433 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13434 From Jim Meyering.
13436 2001-11-12 Akim Demaille <akim@epita.fr>
13438 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13439 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13440 definition used by Automake where LEX is +/- "${missing} lex" and
13441 `missing' itself contains variables.
13443 2001-11-12 Akim Demaille <akim@epita.fr>
13445 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13446 Now that M4sh pushes BODY, the comments were output at the end of
13447 the test suites.
13449 2001-11-08 Akim Demaille <akim@epita.fr>
13451 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13452 that we can trace macros from aclocal.m4.
13453 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13454 obsoleted, and redirect to the former anyway.
13455 Reported by Ralf Corsepius.
13457 2001-11-08 Akim Demaille <akim@epita.fr>
13459 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13460 processed only if present.
13461 * tests/torture.at (Configuring subdirectories): Use autoreconf
13462 instead of successive calls to autoconf.
13463 Add a nonexistent subdirectory to exercise the patch above.
13464 Reported by Ralf Corsepius.
13466 2001-11-08 Kevin Ryde <user42@zip.com.au>
13468 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13469 doesn't accept .S files.

13475 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13476 * bin/autom4te.in (warn_forbidden): New.
13477 (handle_output): Use it.
13478 Read m4_pattern_forbid with messages.
13480 2001-11-05 Akim Demaille <akim@epita.fr>
13482 * bin/autom4te.in (--normalize): Remove.
13483 * lib/autom4te.in: Adjust.
13485 2001-11-05 Akim Demaille <akim@epita.fr>
13487 * tests/Makefile.am (testsuite): Rename this target as...
13488 ($(TESTSUITE)): this.
13489 From Nicolas Joly.
13491 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13493 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13494 the --prefix option, also remove it's argument.
13496 2001-11-05 Akim Demaille <akim@epita.fr>
13498 * doc/autoconf.texi (testsuite Invocation): Update.
13499 (Writing testsuite.at): Update.
13501 2001-11-03 Akim Demaille <akim@epita.fr>
13503 * doc/autoconf.texi: s/@code/@command/ where appropriate.
13505 2001-11-03 Akim Demaille <akim@epita.fr>
13507 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13508 (&file_name_is_absolute): New, wrappers around routines from
13509 File::Spec.
13510 Use and export them.
13511 (&find_configure_ac): Optionally take a directory where to look at.
13512 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13513 the arguments.
13514 Default @ARGV to `.', not find_configure_ac.
13515 (&autoreconf): Argument is a directory.
13516 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13517 * doc/autoconf.texi (autoreconf Invocation): Update.
13519 2001-11-03 Akim Demaille <akim@epita.fr>
13521 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13522 (@export_forward_subs): New.
13523 Add basename, dirname, and fileparse.
13524 (@EXPORT): Adjust.
13525 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13526 Don't look for aclocal flags if we already know aclocal is not
13527 used.
13528 Move aclocal.m4t only if it exists.
13529 Reported by Ezra Peisach.
13531 2001-11-03 Akim Demaille <akim@epita.fr>
13533 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13534 passed on command line, defaulting to ./configure.ac if present.
13535 (&maybe_autoreconf, File::Find): Remove, unused.
13536 (&autoreconf): If autoconf is not used, don't try to trace.
13538 2001-11-02 Akim Demaille <akim@epita.fr>
13540 * configure.ac: Bump to 2.52g.
13542 2001-11-02 Akim Demaille <akim@epita.fr>
13544 Version 2.52f.
13546 2001-11-02 Akim Demaille <akim@epita.fr>
13548 * config/config.guess, config/config.sub, doc/standards.texi:
13549 * config/lispdir.m4: Update from masters.
13550 * configure.ac: Bump to 2.52f.
13552 2001-11-02 Akim Demaille <akim@epita.fr>
13554 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13555 Don't run aclocal when aclocal.m4 is not from aclocal.
13556 From Ezra Peisach.
13557 Don't run libtoolize and gettextize if --install is not given.
13559 2001-11-01 Paul Eggert <eggert@twinsun.com>
13561 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13562 be invoked before _AS_LINENO_PREPARE.
13563 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13564 than character ranges.
13566 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13567 invoking AS_BASENAME. Set the locale variables to 'C' if
13568 possible, as POSIX requires this to get the traditional
13569 behavior.
13570 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13572 2001-10-31 Paul Eggert <eggert@twinsun.com>
13574 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13575 with {}, as that triggers a bug in Bash 2.05.
13577 (_AS_LINENO_PREPARE): Use Sed rather than
13578 Awk. Fix the sed prepass to work even if there are multiple
13579 instances of $LINENO on the same line. Do not substitute for
13580 other variables like $LINENOT. Do not check file dates; such a
13581 check is unreliable on sufficiently fast machines, and removing
13582 the check makes the code simpler and more reliable. Check for
13583 output and chmod failures.
13585 * doc/autoconf.texi (Special Shell Variables): Document
13586 the above.
13588 2001-10-31 Akim Demaille <akim@epita.fr>
13590 * tests/Makefile.am (atconfig): Remove this target, Automake
13591 handles it now.
13593 2001-10-31 Akim Demaille <akim@epita.fr>
13595 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13596 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13597 provided, while it is optional.
13598 * configure.ac: Adjust.
13600 2001-10-26 Paul Eggert <eggert@twinsun.com>
13602 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13603 lib/Autom4te/Struct.pm:
13604 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13605 with 5.005_02.
13607 * doc/autoconf.texi (Special Shell Variables): Document some
13608 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13610 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13611 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13612 eval $LINENO is not portable in practice.
13614 2001-10-24 Akim Demaille <akim@epita.fr>
13616 * lib/Autom4te/General.pm (backname): New.
13618 2001-10-24 Akim Demaille <akim@epita.fr>
13620 * m4/: Remove, merged into...
13621 * config/: here.
13623 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
13625 * doc/autoconf.texi (Shellology): Mention the problems with bash
13626 2.05's use of ANSI quoting in its `set' builtin.
13628 2001-10-22 Paul Eggert <eggert@twinsun.com>
13630 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13631 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13632 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13633 POSIX decided to standardize on the int flavor of strerror_r.
13634 Always do char* test, as there's no reason not to.
13635 Assign to a char* var, to catch strerror_r that returns int*.
13637 * doc/autoconf.texi (Particular Functions):
13638 Document the above changes. Also, document the fact that
13639 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13641 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13643 2001-10-20 Akim Demaille <akim@epita.fr>
13645 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
13646 the executable was missing from the log.

13650 * lib/Autom4te/General.pm (&update_file): If destination is
13651 unchanged, remove the source.
13652 (&up_to_date_p): Don't be verbose, be debug.
13653 * bin/autoreconf.in: No longer support --m4dir.
13654 (&autoreconf): Display the full path of the configure.ac we are
13655 studying.
13656 Trace it only once.
13657 Be sure to honor --force with gettextize.
13658 Always run aclocal.
13659 * doc/autoconf.texi: Adjust.
13661 2001-10-20 Akim Demaille <akim@epita.fr>
13663 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
13664 Remove, dead.
13665 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13666 `intl' is already present, as it refuses unless --force.
13667 (&parse_args): Use -I, --include instead of the old Autoconf
13668 options.
13669 ($localdir, $autoconf_dir): Remove.
13670 (@include): New.
13671 (&maybe_autoreconf): New, to preserve $_ for File::Find.
13673 2001-10-19 Jens Petersen <petersen@redhat.com>

13682 Don't mention `automatically' in addition to `generated'.
13683 * tests/torture.at (#define header templates): Adjust.
13685 2001-10-19 Akim Demaille <akim@epita.fr>
13687 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
13688 comment, explain how to install automatic mode selection.
13689 From Russ Allbery.
13691 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
13693 * bin/autoreconf.in (autoreconf): Display the path to the
13694 configure.ac being studied.
13696 2001-10-18 Paul Eggert <eggert@twinsun.com>
13698 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
13699 long, to work around a bug in the HP C compiler version HP92453-01
13700 B.11.11.23709.GP.
13702 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
13703 (AS_BASENAME_EXPR): New macro.
13704 (AS_BASENAME_SED): Do not assume GNU sed semantics.
13705 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
13706 and fall back on 'sed' only if the other two fail. This makes
13707 AS_BASENAME act more like AS_DIRNAME.
13708 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
13709 contains white space.
13710 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
13711 Use AS_DIRNAME, since I think it's now DOS-friendly.
13712 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
13713 Allow "dirname //FOO" to return either / or //, as POSIX allows
13714 either behavior.
13716 2001-10-10 Akim Demaille <akim@epita.fr>
13718 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

13720 From Eric Sharkey.

13724 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

13819 2001-10-08 Akim Demaille <akim@epita.fr>
13821 Use `add-log-current-defun-function' for ChangeLog creation.

13853 shell does not support LINENO, and if CONFIG_SHELL is unset or
13854 empty, and if we can find a shell that does support LINENO,
13855 then set CONFIG_SHELL to that shell and then re-execute
13856 ourselves with CONFIG_SHELL.
13858 2001-10-05 Paul Eggert <eggert@twinsun.com>
13860 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
13861 doesn't exist. Remove *.tmp, as a .tmp file is created during the
13862 build of $(TESTSUITE).
13864 2001-10-05 Akim Demaille <akim@epita.fr>
13866 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

13887 (AS_SHELL_SANITIZE): here. Use it.
13888 (_AS_LINENO_PREPARE): Preserve the exit status of $0.lineno.
13889 From Paul Eggert.
13891 2001-10-04 Akim Demaille <akim@epita.fr>
13893 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable
13894 combination of Awk and sed to replace $LINENO.
13896 2001-10-02 Paul Eggert <eggert@twinsun.com>
13898 * doc/autoconf.texi (Limitations of Builtins): You can't use
13899 "source"; it's not portable. Remove confusing and
13900 somewhat-incorrect example involving "." and "/".
13902 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
13903 compatibility with POSIX shells.
13905 2001-10-02 Akim Demaille <akim@epita.fr>
13907 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
13908 instead of exec'ing to preserve $0 and $@.
13910 2001-10-01 Akim Demaille <akim@epita.fr>
13912 * tests/testsuite (AT_INIT) <at_pass_list>: New.

13931 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
13932 Don't use nested parenthesization. This patch was originally
13933 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
13934 but somehow it didn't get incorporated then.
13935 * doc/autoconf.texi (Limitations of Usual Tools):
13936 Clarify remark about sed and nested parenthesization.
13938 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
13939 Report an error if the size cannot be determined even though
13940 the type exists.
13941 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13942 Check for `expr' arithmetic overflow, and for compilation failure,
13943 and invoke a new argument $4 if either is discovered.
13944 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
13945 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
13947 2001-09-28 Akim Demaille <akim@epita.fr>

13955 * lib/autotest/general.m4 (AT_VICTIMS): Rename as...
13956 (AT_TESTED): this.

13958 Output `AT_tested' only when existing.
13959 Catch unexpanded PACKAGE_STRING and PACKAGE_BUGREPORT.
13961 2001-09-27 Akim Demaille <akim@epita.fr>
13963 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
13964 generates too many bug reports.
13966 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
13967 status when executing the ACTION-IF-FALSE.
13968 * tests/base.at (AC_TRY_*): Rename as...

13975 * tests/c.at (Extensions, C keywords)
13976 (Broken/missing compilers, AC_PROG_CPP with warnings)
13977 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
13978 (AC_PROG_CPP requires AC_PROG_CC): here and...
13979 * tests/fortran.at (GNU Fortran 77): there.
13980 * doc/autoconf.texi (autoconf Invocation): Fix the example:
13981 AC_TRY_RUN is about compilation, not shell commands.
13982 (Test Programs): AC_TRY_RUN works as used to be advertised.
13984 2001-09-27 Akim Demaille <akim@epita.fr>
13986 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
13987 Raja R Harinath:
13988 Be sure to detect when $LINENO always returns the same value.
13989 Look for the original script, basename($0) is certainly not
13990 enough.
13991 Pass the CLI arguments to `$as_me.lineno'.
13993 2001-09-25 Akim Demaille <akim@epita.fr>
13995 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

14003 of --language now.
14005 2001-09-23 Akim Demaille <akim@epita.fr>
14007 * doc/autoconf.texi (Top): Wrap in @ifnottex.
14009 2001-09-23 Akim Demaille <akim@epita.fr>
14011 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
14012 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
14013 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
14014 builddir, buildpath, top_builddir, and top_buildpath.
14015 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
14016 the current directory.
14017 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
14018 variables *before* changing the current directory.

14021 variables.
14023 * lib/autotest/general.m4: Do not reset AT_victims.
14024 Don't compute at_srcdir nor at_top_srcdir.
14026 * tests/tools.at: Hence use top_srcdir.
14028 * tests/Makefile.am, tests/autoconf, tests/autoheader,
14029 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
14030 Remove.

14032 * tests/wrapsh.in, tests/autoupdate.in: New.
14033 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
14034 * configure.ac: Build the position independent wrappers.
14036 * man/Makefile.am: Now that test wrappers are position
14037 independent, use them and drop dark envvar magic.
14039 2001-09-23 Akim Demaille <akim@epita.fr>
14041 * doc/autoconf.texi (Common Shell Constructs): Rename as...
14042 (Programming in M4sh): this.

14070 (Autoconf): Adjust.
14072 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
14074 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,

14083 2001-09-22 Akim Demaille <akim@epita.fr>
14085 * lib/autoconf/autotest.m4: Create `package.m4'.
14086 * tests/Makefile.am (package.m4): Remove.
14088 2001-09-22 Akim Demaille <akim@epita.fr>
14090 Rely on `$LINENO' when possible instead of `__oline__'.
14092 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
14093 `$LINENO' support replacement when not supported.
14094 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
14095 them explicitly to be sure they are not output before this section
14096 (via m4_require). Cosmetic only.
14097 * lib/autoconf/c.m4, lib/autoconf/general.m4,
14098 * lib/autoconf/programs.m4: Replace all the occurrences of
14099 `__oline__' with `$LINENO'.

14102 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
14104 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
14105 character (u: -> ue) in a code comment.
14106 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
14107 it works.
14109 2001-09-21 Akim Demaille <akim@epita.fr>
14111 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
14112 Suggested by Jim Meyering.
14114 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14116 * lib/autoconf/programs.m4: Use extensions listed in
14117 $ac_executable_extensions when looking for programs.
14119 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14121 * lib/autoconf/general.m4: Fix a small Englisho.
14122 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
14123 setting up ac_dir_suffix and ac_top_builddir.
14124 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
14126 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14128 * doc/autoconf.texi (File System Conventions): Clarify the use of
14129 PATH_SEPARATOR.
14130 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
14131 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
14132 be used instead of ':'.
14133 * lib/autotest/general.m4: Replace occurrences of ':' in
14134 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14136 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14138 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14139 arguments. Fixed a typo.
14141 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14143 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14144 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14146 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14148 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
14149 * bin/autoupdate.in: Ditto.
14150 * bin/autoheader.in: Reworded a few comments.
14151 * bin/autoconf.in: Reworded help text for a few options.
14152 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
14153 * bin/autoscan.in, bin/autoupdate.in: Ditto.
14155 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14157 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14158 already have $file). Set output files to binary mode (helps avoid
14159 CR issues on DOSish systems).
14161 2001-09-19 Akim Demaille <akim@epita.fr>
14163 * lib/autotest/general.m4: Englishoes.
14164 From Tim Van Holder and Alexey Mahotkin.
14166 2001-09-18 Paul Eggert <eggert@twinsun.com>
14168 * doc/autoconf.texi (Common Shell Constructs): New node,
14169 documenting AS_DIRNAME.
14170 (Limitations of Usual Tools): Refer to it when discussing dirname.
14171 Also, update discussion of POSIX standard to reflect latest draft.
14173 * lib/autoconf/c.m4:
14174 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14176 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14177 Do not pass a first argument with leading '-'
14178 to expr, by parenthesizing initial integers that might be negative.
14180 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14181 now merely checks whether it is an error to pass an argument
14182 to getpgrp.
14184 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14185 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14186 whether it is a (compile-time) error to pass an argument to
14187 getpgrp. This simpler test supports the revised documentation,
14188 and is all that AC_FUNC_GETPGRP's users really need.
14190 2001-09-18 Akim Demaille <akim@epita.fr>
14192 * doc/autoconf.texi (Limitations of Make) <$<>: New.
14194 2001-09-18 Akim Demaille <akim@epita.fr>
14196 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
14197 `{}'.
14198 * lib/autotest/general.m4 (AT_INIT): Adjust.
14200 2001-09-18 Paul Wagland <paul@wagland.net>
14202 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14203 correctly.
14204 Add test for AS_BASENAME.
14205 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14206 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14207 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14208 * tests/base.at: Fixed the expected responses. The old ones were
14209 one line out...
14210 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14211 the documentation claims it should (and how it behaved in 2.13).
14213 2001-09-18 Akim Demaille <akim@epita.fr>
14215 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14216 the AC_CONFIG_COMMANDS invocation.
14217 This also solves the name clash problems.
14218 Don't set the package's ID.
14219 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14220 No longer to be shipped.
14221 (version.in): Remove.
14222 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14223 * lib/autoconf/status.m4: Adjust.
14224 Use `m4_PACKAGE_STRING'.
14225 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14226 the only optional argument is the name of the test suite.
14227 Expect `package.m4' to define the package signature.
14228 * lib/autom4te.in (Autotest): Add `package.m4?'.
14229 * tests/Makefile.am (package.m4): New.
14230 * tests/suite.at: ifnames is a victim.
14232 2001-09-18 Akim Demaille <akim@epita.fr>
14234 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14235 AC_LIBSOURCE, AC_CONFIG_FILES.
14236 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14237 program version string doesn't match the package's.
14238 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14239 after `(cached)'.
14241 2001-09-17 Paul Eggert <eggert@twinsun.com>
14243 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14244 Allow expression to return any value that can fit into unsigned long
14245 (not int, as before). Check for output errors.
14247 2001-09-17 Bruno Haible <haible@ilog.fr>
14249 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14250 Always include <stdio.h> and <stdlib.h>. Evaluate
14251 the expression in an extra function before these includes. Call
14252 fprintf "%d" only after ensuring the argument is of type 'int'.
14253 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14255 2001-09-17 Paul Eggert <eggert@twinsun.com>
14257 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14258 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14259 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14260 when they don't exist.
14262 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14263 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14264 need it.
14266 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14267 version with the version used by fileutils 4.1, except use
14268 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14269 we don't need it.
14271 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14273 2001-09-13 Akim Demaille <akim@epita.fr>
14275 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
14276 _first_.
14277 Reported by Gerrit P. Haase.
14279 2001-09-13 Akim Demaille <akim@epita.fr>
14281 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
14282 m4_defn'ing is valid.
14284 2001-09-13 Akim Demaille <akim@epita.fr>
14286 * lib/m4sugar/m4sugar.m4 (m4_append_uniq): New.
14287 * lib/autotest/general.m4 (AT_VICTIMS, AT_KEYWORDS, _AT_CLEANUP_FILE):
14288 Use it.
14290 2001-09-13 Akim Demaille <akim@epita.fr>
14292 * lib/m4sugar/m4sugar.m4 (_AS_QUOTE_IFELSE, _AS_BOX_INDIR): Use
14293 m4_match.
14294 (m4_re_escape): New.
14295 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER): Use it.
14296 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.

14313 * lib/autotest/general.m4 (AT_INIT): Create and remove
14314 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

14425 2001-09-05 Akim Demaille <akim@epita.fr>
14427 Be ready to handle filenames as stupid as `dnl.at', for if even
14428 the maintainer is dumb enough to do that...
14430 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14431 excellence in M4 quotation: consider `__file__' is active.
14433 And BTW, when invoking m4, pass the --include in the right order:
14434 the wrong one.
14436 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
14437 4m.

14464 New, extracted from main.
14465 Use IO::File wherever possible.
14466 (input.m4): Be constant, use -I instead of hard coding $tmp.
14467 Therefore be a quoted heredoc.
14468 Don't invoke `_au_disable', since ac was not loaded, but just
14469 `unm4.m4'.
14471 2001-08-31 Akim Demaille <akim@epita.fr>
14473 Version 2.52d.

14498 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
14499 (testsuite Scripts): There is no such thing as `atconfig.in'.
14500 And actually one diagram is missing: test suite runtime.
14502 2001-08-31 Akim Demaille <akim@epita.fr>
14504 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
14505 inverse order.
14507 2001-08-31 Akim Demaille <akim@epita.fr>
14509 * bin/autoupdate.in (@include): `installcheck' revealed the path
14510 to m4sugar was lacking!
14512 2001-08-31 Akim Demaille <akim@epita.fr>
14514 * man/Makefile.am (.x.1): We really have to pass
14515 autom4te_perllibdir.
14517 2001-08-31 Akim Demaille <akim@epita.fr>
14519 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

14525 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
14526 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
14527 Use directly autom4te, not autoconf.

14530 2001-08-31 Akim Demaille <akim@epita.fr>
14532 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

14552 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
14553 (autoheader): Pass --force since the test suite goes too fast for
14554 the time stamps.
14555 Adjust to the new autoheader messages.
14557 2001-08-31 Akim Demaille <akim@epita.fr>
14559 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
14560 Check the completeness of the #template.

14569 Drop AC_MACRODIR dead for real.
14570 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
14571 `autoheader: `config.hin' is created'.
14572 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
14574 2001-08-31 Akim Demaille <akim@epita.fr>
14576 * bin/autoheader.in: Rewrite in Perl.
14577 * tests/autoheader: Adjust.
14579 2001-08-31 Akim Demaille <akim@epita.fr>
14581 * bin/autoconf.in (--include, -I): New option.
14582 Map --localdir, --autoconf-dir onto it.
14583 Forward autom4te's options instead of interpreting them.
14584 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
14585 There is no such envvar since the inception of autom4te.cfg.
14586 * bin/autom4te.in (&parse_args): Uniquify `@include'.
14587 * bin/autoupdate.in: Adjust, and perform more control.

14591 2001-08-31 Akim Demaille <akim@epita.fr>
14593 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
14594 * bin/autom4te.in (&find_file): Support `FILE?' standing for
14595 optionally `FILE'.
14596 Use -e, not -f, since /dev/null for instance is OK.
14597 (&parse_args): Adjust.
14598 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
14600 2001-08-31 Akim Demaille <akim@epita.fr>
14602 * configure.ac: Also find tested executables in bin.
14603 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
14604 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
14605 installed peer executables, only PATH is allowed to resolve it.
14606 Pass `autoconf_dir' via options, not via invisible envvars.
14607 * lib/Autom4te/General.pm (&find_peer): Remove.
14608 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
14609 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
14610 * man/Makefile.am: Let help2man rely on PATH instead of trying to
14611 find the executables for it.
14612 * tests/Makefile.am: Major cleanup. Too lazy to document...
14613 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14614 We only need PERL.
14615 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14616 indeed related to running the test suite, while passing
14617 --autoconf-dir and others is related to running non installed
14618 Autoconf executables. So don't do that, leave it to...
14619 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
14620 * tests/autoscan: New.
14621 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
14622 refer to library files: rely on --language.

14626 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

14635 2001-08-29 Akim Demaille <akim@epita.fr>
14637 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
14638 Suggested by Paul Eggert.
14640 2001-08-29 Akim Demaille <akim@epita.fr>
14642 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
14643 download in a tmp dir.
14645 2001-08-29 Akim Demaille <akim@epita.fr>
14647 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

14664 2001-08-29 Akim Demaille <akim@epita.fr>
14666 * lib/autotest/general.m4: Use
14667 foo=`(command) 2>/dev/null`

14670 (at-devnull): Rename as...
14671 (AT-devnull): this.
14672 (--clean): Remove AT-* files too.
14673 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.

14708 * lib/autotest/general.m4 (AT_INIT): Log the command line.
14709 Support `VAR=VAL' as arguments.

14729 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
14730 `ac_top_builddir' to mimic Automake's vocabulary, which much more
14731 readable.
14732 Adjust callers.
14733 * doc/autoconf.texi (Configuration Actions): Document the vars
14734 available in commands.
14735 Emphasize the risks of collisions in init-cmds.

15193 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15194 magic values from an object file when cross-compiling.
15195 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15197 2001-08-10 Akim Demaille <akim@epita.fr>
15199 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15200 effects.
15201 Suggested by Russ Allbery.
15203 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15205 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15206 current $prefix to the sub-configures.
15208 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15210 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15211 extension (needed on BeOS). Reported by Guido van Rossum.
15213 2001-08-09 Akim Demaille <akim@epita.fr>
15215 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15217 2001-08-07 Akim Demaille <akim@epita.fr>
15219 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15220 removed.
15221 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15222 No need to remove the files before and after the each test, before
15223 each test and at the end of the suite is enough.
15224 Display only the children `times', not the shell's.
15225 If the test failed or was skipped, at-times is not available.
15227 2001-08-07 Akim Demaille <akim@epita.fr>
15229 Always produce testsuite.log, including when there are no
15230 failures. This helps getting information on skipped tests, and
15231 duration of the tests. Err, implement the latter btw.
15233 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15234 Dump information on the first run of each test.
15235 (AT_CLEANUP): Create `at-times' containing the duration of the
15236 test group.
15238 2001-08-07 Akim Demaille <akim@epita.fr>
15240 The use of `dumpstat' revealed that `len' was used although it
15241 should not. m4_text_wrap was using it, but in the Autoconf world
15242 where it is legal. Hence (i) test M4sh in its own world, not
15243 Autoconf's, and (ii), ahem, fix the bug :)
15245 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15246 does not like `' instead of [].
15247 (AT_INIT): Forbid `^_?AT_'.
15248 And don't output such tokens.
15249 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15250 `script.as', and `autom4te.cache'.
15251 Remove `empty' and `macro' which are no longer used.
15252 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15253 * tests/m4sugar.at: Use it.
15254 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15256 2001-08-07 Akim Demaille <akim@epita.fr>
15258 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15260 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15262 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15264 2001-08-04 Akim Demaille <akim@epita.fr>
15266 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15267 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15268 AC_TRY_LINK.
15269 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15270 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15271 (AC_F77_MAIN): Likewise.
15273 2001-08-04 Akim Demaille <akim@epita.fr>
15275 Don't rely on M4sugar outputting the patterns in files, since we
15276 might process the output _without_ running m4, hence without these
15277 files.
15279 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15280 * bin/autom4te.in (@Request::includes): Remove, unused.
15281 (@Request::source): Rename as...
15282 (@Request::input): this.
15283 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15284 (&handle_output): Fetch the patterns from the traces.
15285 `$forbidden' and `$allowed' are constant: use m//o.
15286 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15287 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15289 2001-08-04 Akim Demaille <akim@epita.fr>
15291 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15292 autoconf', i.e., in addition to caching traces, cache the output.
15294 * bin/autom4te.in (Request::cache): Rename as...
15295 (Request::id): this.
15296 ($cache, $icache, $tcache, $ocache): New.
15297 (&handle_m4): Save M4 output in the cache instead of $tmp.
15298 (&handle_output): Adjust.
15299 (&up_to_date_p): Check that the output cache is up to date too.
15300 (top level): Run `&handle_m4' iff force or the cache is invalid.
15301 Run `&handle_output' if the output cache is more recent.
15303 2001-08-04 Akim Demaille <akim@epita.fr>
15305 * bin/autom4te.in ($force): New.
15306 (&parse_args, &print_usage): -f, --force is a new option.
15307 (&handle_output): CPP directives might have spaces after `#'.
15308 (&parse_args): The first file only can be frozen.
15310 2001-08-04 Akim Demaille <akim@epita.fr>
15312 Don't let autom4te compute the `include' traces several times:
15313 first check that the trace cache file is up to date, and then
15314 compare its timestamp with that of the output.
15316 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15317 the preamble. Don't require 5.005 as Autom4te::General does it,
15318 and better yet (use `use', not `require'!).
15319 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15320 Class::Struct as Autom4te::Struct.
15321 * lib/Autom4te/General.pm (File::stat): Use it.
15322 (&mtime): New, export it.
15323 * bin/autom4te.in: Use it.
15324 Declare `$req' is invalid if it is outdated.
15325 Don't declare it valid before saving it if something went wrong.
15327 2001-08-04 Akim Demaille <akim@epita.fr>
15329 Autom4te shall not encode Autoconf data, and preselecting traces
15330 must be proposed to the users.
15332 * bin/autom4te.in (@required_trace): Remove.
15333 (@preselect): New.
15334 (&parse_args, &print_usage): -p, --preselect is a new option.
15335 (&up_to_date_p): Adjust.
15336 * bin/autoconf.in: Preselect some Autoconf macros.
15338 2001-08-04 Akim Demaille <akim@epita.fr>
15340 * tests/tools.at (autoconf --trace: user macros): Check traces on
15341 macros invoked without arguments, and macros invoked with multiple
15342 lines arguments.
15344 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
15346 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
15347 arguments.
15349 2001-08-03 Akim Demaille <akim@epita.fr>
15351 * bin/autoconf.in ($@): Work around the usual sh bug.
15352 From Nicolas Joly.
15354 2001-08-03 Akim Demaille <akim@epita.fr>
15356 Clean up the handling of the M4 builtins tracing exception.
15358 * bin/autom4te.in (Request::request): Don't complete M4 builtins
15359 trace requests.
15360 (@m4_builtins): Rename as...
15361 (@m4_builtin): this.
15362 (%m4_builtin_alternate_name): New.
15363 (&parse_args): Complete the trace requests with alternate names.
15364 (&handle_traces): Hence no longer do it here.
15365 (&trace_requests): Remove, unused.
15367 2001-08-03 Akim Demaille <akim@epita.fr>
15369 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
15370 m4_if, and m4_wrap.
15372 2001-08-03 Akim Demaille <akim@epita.fr>
15374 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
15375 (m4_divert_pop): Dump the whole diversion stack when a diversion
15376 mismatch happens.
15377 * bin/autom4te.in (&handle_output): Remember of the first
15378 occurrence of a possibly undefined macro, not the last.
15379 Complain about the possibly undefined macros in the same order as
15380 the appear in the output.
15381 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
15382 * tests/tools.at (autoconf: forbidden tokens, basic)

15384 autoconf's stderr, as it is now deterministic.
15385 Check that `dnl' is caught.
15387 2001-08-01 Akim Demaille <akim@epita.fr>
15389 * configure.ac: Bump to 2.52c.

15407 `END', as `Autom4te::General::END' will be triggered.
15408 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
15409 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

15844 cross-language link tests can be performed successfully.
15845 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
15846 after $LIBS, for consistency; this should be the general rule since
