980 The test suite did not cover this bug because the code was not
981 quoting properly the arguments of `rm -f' (which "fails" silently)
982 as well as the arguments of `diff' (whose output was redirected to
983 /dev/null so we couldn't see its error message).
984 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the

1083 regression in sourcing files.
1084 * tests/autotest.at (Using atlocal): New test to catch this.

1104 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
1105 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
1106 <PARSE_ARGS>: Parse new option.
1107 <HELP_TUNING>: Document it.
1108 * tests/autotest.at (Choosing where testsuite is run): New test
1109 for this feature.
1110 (Keywords and ranges): Add test for missing -k argument.
1111 * NEWS: Document this.
1112 * doc/autoconf.texi (testsuite Invocation): Likewise.
1114 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1116 * build-aux/config.guess, build-aux/config.sub,
1117 build-aux/texinfo.tex: Sync from gnulib.
1118 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
1119 Likewise.
1121 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1123 * doc/autoconf.texi (Particular Programs): Do not mention the
1124 Autoconf version in which the AC_PROG_INSTALL change was done.
1125 Suggested by Paul Eggert.
1127 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1129 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1130 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1131 mode, we change to the source directory, also set $ac_pwd so we
1132 do not go back to the build tree for the next config subdir.
1133 * tests/torture.at (Deep Package): Extend test to contain two
1134 config subdirs on the top level.
1136 Fix parallel `maintainer-check'.
1137 * Makefile.am (maintainer-check-tests): Depend on `all'.

1168 check_SCRIPTS. Building the wrappers for `all' allows help2man
1169 to use them for the manpages.
1170 Report by Benoit Sigoure.

1185 Fix thinko in earlier patch - m4_join isn't defined yet.
1186 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1187 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1188 (m4_require): Use m4_do, not m4_join.
1190 Fix some whitespace tests on cygwin.
1191 * tests/tools.at (autom4te and whitespace in file names): Restore
1192 font-lock. Create $TMPDIR before it might be used.

1195 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1197 Optimize AC_REQUIRE.
1198 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1199 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1200 (m4_require): Avoid extra macro calls.
1202 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1204 * tests/torture.at (srcdir): Fix quoting.
1206 Do not pass top_srcdir to configure scripts in testsuite.
1207 * tests/autotest.at (srcdir propagation): Copy install-sh to
1208 source tree.
1209 (my only test): Drop setting of `top_srcdir'.
1210 * tests/base.at (Input/Output): Likewise.
1211 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1212 config.guess, and config.sub to test source tree.
1213 Drop AC_CONFIG_AUX_DIR setting.
1214 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1215 * tests/torture.at (Substitute a 2000-byte string): Drop
1216 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1217 (Substitute a newline, datarootdir workaround): Likewise.
1218 (Define a newline): Adjust for linenumber changes in configure.ac.
1219 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
1221 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
1222 if `pwd` contains whitespace.
1224 Quote $abs_top_srcdir in tests.
1225 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
1226 * tests/tools.at (Syntax of the shell scripts): Likewise.
1228 * tests/m4sh.at (LINENO): Quote $0.
1230 Fix testsuite program wrapper for whitespace in `pwd`.
1231 The problem here is that the usual mantra is that command
1232 variables can contain arguments, thus we cannot just escape
1233 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1234 $top_builddir/tests directory early in $PATH, so that the
1235 wrappers are found by their plain name.
1236 * tests/wrapper.as: Put $testdir early in $PATH.
1237 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1239 Proper config.status --file/--header and $srcdir escaping.
1240 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
1241 characters in $ac_file_inputs.
1242 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
1243 accordingly.
1244 * tests/torture.at (datarootdir workaround): Adjust.
1245 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
1247 Fix Autotest for whitespace in `pwd`.
1248 * lib/autotest/general.m4 (AT_INIT)
1249 <at_func_create_debugging_script, Driver Loop>:
1250 Quote $at_group_dir.
1251 * tests/autotest.at (whitespace in absolute testdir): New test.
1253 * lib/autom4te.in: Quote @datadir@.
1255 Proper file name escaping in Autoconf programs and Perl modules.
1256 This includes escaping of characters special to the shell
1257 as well as special to Perl, e.g., leading `<' or `>'.
1258 For example, when $file starts with `>', `open ">$file"'
1259 wrongly tries to append to a different file.
1260 * bin/autoconf.as: Fix quoting for autom4te options.
1261 * lib/Autom4te/General.pm (shell_quote): New function, taken
1262 from coreutils, written by Jim Meyering.
1263 (mktmpdir): Use it.
1264 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
1265 and open_quote.
1266 * bin/autoreconf.in (parse_args): Likewise.
1267 * bin/autoscan.in (main): Likewise.
1268 * bin/autoupdate.in (main): Likewise.
1269 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
1270 * bin/ifnames.in: Likewise, XFile usage fixes.
1271 * tests/tools.at (autom4te and whitespace in file names): Extend
1272 test. Test twice, with special characters allowed on w32, and the
1273 rest. Test leading and trailing whitespace, for `open_quote'.
1274 (autotools and whitespace in file names): New, analogous test.
1275 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1276 by Russ Allbery and Eric Blake.
1278 Sync from Automake.
1279 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
1280 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1281 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1282 (update_file, contents): Use it.
1284 * Makefile.am (autom4te-update): Rewrite for git.
1286 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1288 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1290 Fix copyright years.
1291 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1292 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.

1296 Manually resync with gnulib, since 'make cvs-update' no longer works.
1297 * build-aux/config.guess: New upstream version.
1298 * build-aux/config.sub: Likewise.
1300 When using older automake, don't downgrade build-aux/texinfo.tex.
1301 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1302 * doc/Makefile.am (TEXINFO_TEX): Add.
1304 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1306 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1307 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1308 #undef as this runs afoul of our new way of creating config.h.
1309 Problem reported by Jim Meyering in
1310 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
1312 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1314 Fix autom4te for unusual characters in input file names.
1315 * bin/autom4te.in (files_to_options): Quote active characters
1316 for the shell.
1317 * tests/tools.at (autom4te and white space in file names):
1318 New test.
1320 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1321 Document that Tru64 awk always splits $0.
1323 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1325 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1326 `#AT_STOP_...' line at the end of each test.
1328 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1330 * lib/autotest/general.m4 (AT_INIT): For awk line number
1331 extraction script, ensure `$at_group' has a defined value
1332 even for the empty set, and properly quote its usage inside
1333 the awk script.
1335 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1337 * doc/autoconf.texi (Shell Functions): New chapter. Document
1338 IRIX sh $0 issue in functions, move content from ...
1339 (Portable Shell): ... here.
1340 (Shell Script Compiler): Note that shell functions are not
1341 totally unportable any more.
1343 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1344 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1346 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
1347 extracting the line numbers of the last needed test.
1349 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1351 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1352 Fix quoting.
1354 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1356 Fix IRIX testsuite debugging failures: $0 in functions.
1357 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1358 Do not use $0 inside a function, as IRIX sh will set that to the
1359 function name rather than the script invocation name.
1361 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1362 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1364 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1365 to extract test scripts.
1366 (AT_INIT): Extract and cache test script line numbers.
1368 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1370 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1371 subsequent fixups; the awk -> here-document conversion trashes
1372 performance too much with AIX sh.
1374 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1376 * tests/local.at: Do not test m4, perl with AT_TESTED.
1378 Diagnose and guard against write errors dealing with config.status.
1379 The general idea is this: all write failures from `configure'
1380 writing `config.status' are indicated by $ac_write_error, which
1381 is only checked at the end. This is safe because config.status
1382 code is not executed before the file is complete. Other write
1383 failures, be they inside config.status, or in sub shell/awk
1384 scripts spawned from configure or config.status, typically need
1385 earlier checking, as their results are used right afterwards.
1386 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1387 before writing config.status, check afterwards.
1388 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1389 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1390 Set `ac_write_error' for write failures to config.status. Barf
1391 upon write failures to temporary files.
1392 Adjust note about closing and reopening the here-document.
1393 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1394 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1395 reopening the here-document.
1396 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1397 Ensure `ac_write_error' does not escape into config.status.
1398 Also, add a couple of code paths not yet exercised in the test
1399 suite: a config file with input from stdin, and a config header
1400 output to stdout.
1401 Suggestion for catching write errors by Bruno Haible.
1403 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1405 Avoid error with Tru64 awk and testsuite lines with many words.
1406 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1407 reads the testsuite, set the field separator to an unusual value,
1408 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1409 even splits the input if $i, i>0, was never accessed in the script.
1411 Revert 2007-10-17 change.
1412 * TODO: Multiline args in config files and headers mean something
1413 different and are not fixed, see

1419 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1421 AC_*_TOOL does not canonicalize the prefix
1422 * doc/autoconf.texi (Generic Programs): Do not say that

1427 Diagnose write errors in config.status instantiations.
1428 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)

1469 * lib/autoconf/status.m4: Fix a couple of comment typos.
1471 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1473 2007-11-13 Jim Meyering <meyering@redhat.com>
1475 Clean up the rule to create "expr".
1476 * tests/Makefile.am (expr): Don't redirect directly to target.
1477 Redirect just once, not for each echo statement.
1478 Use $@, not literal "expr".
1480 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1482 Don't worry about preprocessor when testing long long.
1483 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1484 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1485 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1486 These no longer check for preprocessor flaws.
1487 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1488 Do not check for preprocessor flaws.
1490 2007-11-13 Jim Meyering <meyering@redhat.com>
1492 Adapt dependencies, now that a version change doesn't modify configure.ac
1493 * GNUmakefile: Remove "make clean" kludge.
1494 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1495 configure.ac.
1496 Don't redirect directly to target.
1497 Use $@, not literal "version.m4".
1499 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1501 * doc/autoconf.texi (Making testsuite Scripts): Document
1502 ":;{" shorthand as in previous patch.
1504 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1506 * doc/autoconf.texi (Limitations of Builtins): Document problem
1507 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1508 for the workaround.
1509 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1510 Use ":;{" shorthand.
1511 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1513 2007-11-12 Jim Meyering <meyering@redhat.com>
1515 Add more non-srcdir build support.
1516 * GNUmakefile (dummy): Split a long line.
1517 Add -v option to autoreconf invocation.
1519 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1520 * GNUmakefile (dummy): Remove INSTALL.
1522 Remove racy commands to build scripts in bin/ and tests/.
1523 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1524 are guaranteed to be built, remove the rules that tried to build
1525 them. Before, with a parallel build, these rules could lead to
1526 two processes writing tests/wrapper.in concurrently.
1528 Build in man/ only *after* building in bin/ and tests/.
1529 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1530 in both bin/ and tests/.
1532 Accommodate non-srcdir build-from-checkout.
1533 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1534 Use git's --git-dir=$srcdir/.git option.
1535 Add quotes, in case tarball_version_file contains shell meta-characters.
1536 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1537 * configure.ac: Pass "." to git-version-gen.
1539 Avoid spurious test failures due to version skew.
1540 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
1542 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1544 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
1545 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
1546 Remove conftest.dSYM directory.
1547 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1548 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
1549 Remove `conftest.*' recursively.
1550 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
1551 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1552 Likewise.
1553 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
1554 * THANKS: Update.
1555 Report and analysis by Jeff Squyres and Peter O'Gorman.
1557 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
1559 Fix typos in variable names.
1560 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
1562 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
1564 Document that $((expression)) is not portable.
1565 * doc/autoconf.texi (Shell Substitutions): Here.
1567 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1569 Ignore configure --help* errors due to LINENO-impaired shells.
1570 * tests/torture.at (Configuring subdirectories, Deep Package):
1571 In the --help* tests in read-only trees, make `.' temporarily
1572 writable again for the `stderr' file, and ignore errors due to
1573 the attempt to write configure.lineno.
1574 Report by Patrick Welche.
1576 2007-11-10 Jim Meyering <meyering@redhat.com>
1578 Generate package.m4 in build-dir, not srcdir.
1579 * tests/Makefile.am (package.m4): Adjust target.
1580 Don't redirect directly to $@.
1581 (CLEANFILES): Add package.m4.
1582 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1583 in $(srcdir).
1584 When running $(AUTOTEST), search "." before searching $(srcdir).
1586 Avoid a race condition that would make parallel "distclean" fail.
1587 * tests/Makefile.am (distclean-generic): Replace the default,
1588 automake-provided rule with an identical one, but with an additional
1589 dependency on distclean-local. Simply adding the dependency would
1590 cause automake not to emit the rule at all.
1591 * BUGS: Building with -jN works, now.
1593 Distribute git-version-gen.
1594 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1595 since GNUmakefile is distributed, and requires it for dist* rules.
1597 Remove two more generated files from version control.
1598 * INSTALL: Remove generated file.
1599 * lib/autoscan/autoscan.list: Remove generated file.
1601 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1603 * GNUmakefile (PATH): Remove stray apostrophes; they become
1604 part of PATH, which isn't wanted here.
1606 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1608 New config files output variable `top_build_prefix'.
1609 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1610 `top_build_prefix'.
1611 * doc/autoconf.texi (Preset Output Variables): Document it.
1612 * NEWS: Update.
1613 Report by Bob Friesenhahn.
1615 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1616 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1617 function, to parametrize arithmetic with expr vs. the shell.
1618 Use it where possible.
1619 Suggestion by Benoit Sigoure.
1621 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1623 Adjust the documentation of autotest WRT atlocal.
1624 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1625 when using Automake, to write a rule to produce atlocal, since it's
1626 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1627 distributed, not atconfig.in.
1629 2007-11-04 Eric Blake <ebb9@byu.net>
1631 Update list information.
1632 * README: Mention new autoconf-commit list.
1633 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
1635 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1637 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
1639 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
1641 * build-aux/.gitignore: Ignore mkinstalldirs.
1643 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
1645 2007-11-03 Jim Meyering <meyering@redhat.com>
1647 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1648 * build-aux/git-version-gen: This syncs from coreutils.
1650 Adjust the build procedure so "make check" works reliably.
1651 * README-hacking: Include an extra step between "make" and
1652 "make check" to ensure that the latter passes.
1654 Use just-built tools, when possible.
1655 * GNUmakefile (PATH): Set and export here, ...
1656 (dummy): ... rather than here.
1658 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1659 and Andreas Schwab <schwab@suse.de>
1661 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
1662 exit status bug.
1664 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1666 * configure.ac (AC_PREREQ): Require version 2.60, for
1667 AC_PROG_SED, AC_PROG_GREP.
1669 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
1670 and Jim Meyering <meyering@redhat.com>
1671 and Andreas Schwab <schwab@suse.de>
1672 and Eric Blake <ebb9@byu.net>
1674 Document a bug in GNU Bash with compound commands and redirections.
1675 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
1676 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
1677 workaround.
1679 2007-11-03 Eric Blake <ebb9@byu.net>
1681 Support m4 1.4.5 in testsuite.
1682 * tests/torture.at (Define a newline): Exclude line numbers in
1683 error message.
1684 Reported by Ralf Wildenhues.
1686 2007-11-03 Jim Meyering <meyering@redhat.com>
1688 Remove automake-provided files from version control.

1690 * build-aux/install-sh: Remove file.
1691 * build-aux/missing: Remove file.
1692 * build-aux/mdate-sh: Remove file.
1693 * build-aux/.gitignore: New file.
1694 Suggestion from Ralf Wildenhues.
1696 2007-11-03 Eric Blake <ebb9@byu.net>
1698 Adjust version comparison to account for git snapshot numbers.
1699 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
1700 component separator.
1701 * doc/autoconf.texi (Number processing Macros)
1702 <m4_version_compare>: Document this change.
1703 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
1705 2007-10-30 Bruno Haible <bruno@clisp.org>
1707 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
1708 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
1709 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
1710 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
1711 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
1712 Suggested by Paul Eggert.
1714 2007-10-28 Jim Meyering <meyering@redhat.com>
1716 * README-hacking: Autoconf, Automake, and Perl are required to build.
1717 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
1719 2007-10-28 Jim Meyering <meyering@redhat.com>
1721 README-hacking: Recommend running autoreconf -vi.
1722 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
1723 so that we use just-built tools when they're available.
1724 Suggestions from Ralf Wildenhues.
1726 2007-10-28 Jim Meyering <meyering@redhat.com>
1728 Make inter-release --version output more useful.
1730 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1731 which indicates that it is built using the 19th change set
1732 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1733 is a prefix of the commit SHA1.
1734 * build-aux/git-version-gen: New file.
1735 * configure.ac: Run it to set the version.
1736 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1737 * Makefile.am (dist-hook): Arrange so that .version appears only
1738 in distribution tarballs, never in a checked-out repository.
1739 * .gitignore: Add .version here, too. Just in case.
1740 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1741 not configure.ac, now that the version number changes automatically.
1743 Ensure that $(VERSION) is up to date for dist-related targets.
1744 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1745 git-version-gen doesn't match $(VERSION), but only for dist targets.
1747 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1749 Fix `Deep Package' failure with a configure script early in PATH
1750 * tests/torture.at (Deep Package): Add `.' early in PATH.

1779 problem reported by Bruno Haible in
1780 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
1782 2007-10-22 Eric Blake <ebb9@byu.net>
1784 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
1785 preprocessor.
1787 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
1789 Don't check for bug in HP-UX 11.00 cpp.
1790 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
1791 Use -1ull rather than -1u, since that causes problems with gnulib; see
1792 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
1794 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1810 escaping of backslash in here-documents.
1812 Fix `Deep Package' test failure on FreeBSD.
1813 * tests/torture.at (Deep Package): Do not add `.' to $PATH
1814 unnecessarily. Do not try running `/bin/sh configure' with a
1815 configure script to be found in $PATH, if the shell does not do
1816 this resolution. Fixes test failure on FreeBSD.
1818 Fix config header generation with AIX awk.
1819 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
1820 script, use helper array D_is_set, as `" 0"' does not evaluate

1858 * lib/autotest/general.m4 (BANNERS): New named diversion.
1859 (TESTS_END): Diversion no longer used.
1860 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a

1862 array of banner text from a special diversion.
1863 <PARSE_ARGS_END>: No longer need awk to find banners.
1864 <TESTS>: Banners are no longer processed by main driver loop, so
1865 we no longer need case statement.
1866 (AT_BANNER): Rewrite to populate new diversion.
1867 (AT_SETUP): Each test invokes its own banner. No output is needed
1868 to the TESTS diversion.
1869 * doc/autoconf.texi (Writing Testsuites): Document slight
1870 semantics change.
1871 * tests/autotest.at (AT_BANNERS): Enhance test.

1898 understand --version won't try to behave interactively.

1917 (TEST_GROUPS): ...to this.
1919 Reject FreeBSD m4.

2894 2007-05-21 Paul Eggert <eggert@cs.ucla.edu>
2896 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp
2897 choice, since that's what we do with --enable-largefile etc.
2898 Redo indenting and assignments to simplify things a bit, and make
2899 the parens work with Emacs.
2901 * doc/autoconf.texi (Generic Compiler Characteristics): Fix typo
2902 in my previous change: AC_C_OPENMP -> AC_OPENMP. Reported by Bruno

2978 * lib/autoconf/lang.m4, lib/autoconf/c.m4,
2979 lib/autoconf/fortran.m4, lib/autoconf/erlang.m4: Cleanup of
2980 section titles and other comments; no code change.
2982 2007-05-01 Kevin Ryde <user42@zip.com.au>
2984 * doc/autoconf.texi (Particular Programs): Typo
2985 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
2987 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
2989 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
2990 'configure' will fail if the shell lacks proper support for shell
2991 functions. Suggested by RMS.
2993 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
2995 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
2996 about Solaris /bin/printf '%010000x' 123. Problem reported by
2997 Bruno Haible.
2999 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
3001 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
3002 for a.* when searching for executables, as this prevents users
3003 from having files like a.c. Problem reported by Ralf Wildenhues in:
3004 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
3005 This fixes a problem introduced on 2000-12-19.

3015 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
3016 AC_CHECK_TYPE, AC_CHECK_TYPES.
3017 * doc/autoconf.texi (Generic types): C types must be type-names
3018 (the C terminology), not type-ids (the C++ term). C++ types
3019 must not be anonymous.
3020 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
3021 for C++; this drops support for anonymous struct and union types,
3022 which were problematic anyway.
3023 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
3024 for C++.
3026 2007-04-12 Jim Meyering <jim@meyering.net>

3039 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
3040 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
3041 with objects too. Document the restrictions on its use.
3042 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3043 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3044 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3045 works but the latter doesn't, then it's a valid type.
3046 This lets people use function types and so forth.
3047 For C++ there doesn't seem to be a simple solution, so leave it alone.
3048 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3049 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3050 AC_CHECK_TYPE; that wasn't documented or necessary.
3052 2007-04-11 Stepan Kasal <kasal@ucw.cz>
3054 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

3073 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
3075 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
3076 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by

3097 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
3098 checks for unsigned long long int.
3100 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
3102 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
3103 nonstandard grep R.E. escape sequences.
3105 2007-03-17 Jim Meyering <jim@meyering.net>
3107 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
3108 (Limitations of Usual Tools): Also list \< and \>, and mention that
3109 HP-UX's grep, like the one from Solaris, does not support that syntax.
3111 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3113 * doc/autoconf.texi (Specifying Names): `--host' does not
3114 change the build type.
3116 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
3118 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN

3127 Problem reported by Paolo Bonzini in:
3128 http://lists.gnu.org/archive/html/autoconf-patches/2007-02/msg00024.html
3129 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
3130 universal binaries. Problem reported by Elias Pipping.
3132 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
3134 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
3135 * doc/autoconf.texi (C Compiler): Document this. There is a new
3136 extra argument ACTION-IF-UNIVERSAL.

3152 status of rm so we know when it failed.
3153 If cleaning of test dir failed before running the test, warn.
3154 Output the line separator in verbose mode before the warning
3155 to make clear the warning belongs to the following test.
3157 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>

3172 carriage return.
3173 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
3174 with traditional Awk and begin.
3175 * tests/torture.at (Limitations of Builtins): Document the problem

3180 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
3182 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
3183 input from /dev/null in awk test, so even Solaris /usr/bin/awk
3184 will not wait for input with a script containing only a BEGIN
3185 rule.
3187 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>

3211 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
3212 latest version.
3213 (Shell Substitutions): Note problems with @{var:=value} etc.
3214 Add a new section for problems with @{#var} etc. Problem noted

3218 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3220 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3221 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3222 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3223 substitution will still be done by the special code.
3224 Report by Jim Meyering.

3245 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3247 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3248 early on the reader side, drop stderr of the input to avoid
3249 `broken pipe' error output; this may happen even with shell
3250 builtin `echo' of some bash versions. Reports by Ian Macdonald
3251 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3253 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3265 Fix some wording problems noted by Paolo Bonzini in:
3266 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3267 * doc/autoconf.texi (Signed Overflow Examples): Give more
3268 discussion about the allow_superuser_privileges example,
3269 and change it a bit to make things clearer.
3270 (Optimization and Wraparound): Clarify whether the compiler
3271 will generate an infinite loop for the example derived from
3272 Autoconf's mktime test.
3273 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3274 Also, clarify unsigned multiplication overflow.
3276 2007-01-04 Eric Blake <ebb9@byu.net>
3278 * bin/Makefile.am (RELEASE_YEAR): New macro.
3279 (edit): Use it to supply correct copyright year to scripts.
3280 * bin/autoconf.as (version): Use it.
3281 * bin/autoheader.in ($version): Likewise.
3282 * bin/autom4te.in ($version): Likewise.

3286 * bin/ifnames.in ($version): Likewise.
3288 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3290 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3291 feedback. The most important changes document what happens when
3292 you convert an out-of-range value to a signed integer type, and
3293 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3294 a + b.
3296 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3297 rewrite, taking notions from the recent discussion on the gcc and
3298 autoconf mailing lists; please see
3299 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3300 and follow the many links.
3301 (Integer Overflow Basics, Signed Overflow Examples):
3302 (Optimization and Wraparound, Signed Overflow Advice):
3303 (Signed Integer Division): New sections.
3305 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3307 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3308 preprocessor macro arguments in traced name.
3309 * doc/autoconf.texi (Defining symbols): Document longstanding
3310 support for AC_DEFINE-ing macros with arguments, and document
3311 behavior when the same variable has multiple AC_DEFINEs.
3312 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3313 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3314 macros directly, giving much shorter and simpler code.
3316 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3318 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3319 space before "$ac_configure_args" to prevent a 'config.status
3320 --recheck' failure if ac_configure_args doesn't contain a leading
3321 space. This works around a problem with the XEmacs configure.ac,
3322 which uses the (undocumented) ac_configure_args variable
3323 inconsistently with Autoconf.
3325 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3327 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3328 Include <limits.h>, and use its INT_MAX to rewrite the
3329 j loop so that it does not overflow 'int'. Problem reported by
3330 Ralf Wildenhues in
3331 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3332 Play it safe by shifting left by 1 rather than multiplying by 2,
3333 as GCC is less likely to optimize this away when the value
3334 is signed (when it assumes overflow leads to undefined behavior).
3335 Also, don't assume time_t uses two's complement.
3337 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3339 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3340 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3341 dumps core on it. Report by Tim Rice.
3343 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3345 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3346 --disable-option-checking to --help output even when
3347 AC_PRESERVE_HELP_ORDER is not used.
3348 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3349 --with argument, rather than argument with [-.] replaced by
3350 underscores.
3351 * NEWS: Fix typo in previous change; the news was in the
3352 wrong section.
3354 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3356 * NEWS: Warnings are now generated by default for unknown
3357 --enable-* and --with-* options.
3358 * doc/autoconf.texi (Option Checking): Renamed from
3359 (Configure Option Checking). Tighten up the wording a bit.
3360 (External Software, Package Options): Cross-reference to Option
3361 Checking, and use this to shorten our section.
3362 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3363 "$x" to test "x$foo" != x.
3364 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3365 Don't warn if $enable_option_checking is "no".
3366 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3367 ac_unrecognized_opts to the empty string.
3368 Don't echo the unrecognized opts, as this might mishandle
3369 backslashes or leading -.
3370 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3371 usage next to the other --disable-FEATURE options in the
3372 help string.
3374 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3376 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3377 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3378 Print warning for unrecognized --with and --enable options
3379 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3380 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3381 Disable option checking when subdirs are configured.
3382 (AC_OUTPUT): If warnings are enabled, print warning about
3383 unrecognized --with and --enable options at the end of
3384 the configure output (as well as at the beginning).
3385 * doc/autoconf.texi (Option Checking): New node.
3386 Document new option warning functionality.
3388 2006-12-16 Eric Blake <ebb9@byu.net>
3390 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3391 * NEWS: Start news for current version.
3393 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3395 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3396 Define HAVE_GETMNTENT to 1, not to the empty string.
3397 Problem originally reported by Jochen Friedrich in
3398 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3400 This change prompted by a problem report by Andrey Simonenko in
3401 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3402 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3403 object-like macros only, in the traditional portable character
3404 set.
3405 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3406 Warn about attempts to define things that are not identifiers.
3407 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3408 awful hack that AC_DEFINEd macro names containing parentheses.
3410 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3412 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3413 too drastic, even if Texinfo in theory requires it for info mode.
3415 (config.status Invocation): Renamed back from Recreating a
3416 Configuration).
3417 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3418 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3420 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3422 * NEWS: Version 2.61a.
3424 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3425 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3427 * NEWS: Document changes with echo and printf, and the lack
3428 of limits on the total size of multi-line values of substituted
3429 variables, and the AC_FUNC_FSEEKO fix.
3431 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3433 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3434 Writing configure.ac.
3435 (Autoconf Input Layout): Renamed from configure.ac Layout.
3436 (Recreating a Configuration): Renamed from config.status Invocation.
3437 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3438 (acconfig Header): Renamed from acconfig.h.
3439 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3440 (Writing Testsuites): Renamed from Writing testsuite.at.
3441 (Autom4te Cache): Renamed from autom4te.cache.
3443 * BUGS: Remove mention of VPATH problem, since it's now documented
3444 not to be a bug in the Autoconf build procedure itself, but rather
3445 a problem with the proprietary `make' programs.
3447 * doc/autoconf.texi (Build Directories): Add a cross reference
3448 to VPATH and Make.
3450 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3451 * doc/standards.texi: Sync from gnulib.
3453 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3454 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3455 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3456 generated automatically.
3458 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3460 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3461 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3462 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3464 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3466 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3467 `CEOF$ac_eof' special marker, the awk script cannot contain a
3468 line matching `^CEOF', so this is not needed any more.
3469 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3470 special marker in the test.
3472 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3474 * tests/tools.at (autom4te preselections): Use `find -newer';
3475 remove one of the sleeps.
3477 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3478 more readable, using ...
3479 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3481 * doc/autoconf.texi (autoheader Invocation): Do not double-
3482 quote the parameter of `AH_BOTTOM' in the example.
3484 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3486 * doc/autoconf.texi (Configuration Headers): Remove the
3487 example with multiple input files.
3488 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3489 multiple input files.
3491 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3493 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3494 creating the awk substitution script, handle one input line at a
3495 time, so that the maximum length of a substituted (multi-line)
3496 value is not limited by the size of the sed pattern space.
3497 The trade-off is a slightly repetitive sed script.
3498 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3499 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3500 * tests/torture.at (Substitute a 2000-byte string): Increase the
3501 test with several long lines, they should not be caught by sed
3502 limits any more.
3504 * tests/tools.at (autom4te preselections): New test, to flag
3505 entries missing from autom4te.cfg.
3506 Report by David Byron <dbyron@hheld.com>.
3508 * tests/torture.at (Substitute a 2000-byte string): Actually use
3509 AC_PROG_AWK, so the last change works as intended.
3510 (Substitute and define special characters): Likewise.
3511 (Substitute a newline): Likewise.
3513 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3514 instead of `awk' consistently.
3515 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3516 * tests/torture.at (Torturing config.status): Test both the
3517 result of AC_PROG_AWK and plain awk.
3518 (Substitute a 2000-byte string): Likewise.
3519 (Substitute and define special characters): Likewise.
3520 (Substitute a newline): Likewise.
3522 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3524 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3525 can be assigned to a function pointer. Problem reported by
3526 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3527 part of a patch by Ralf Wildenhues in that same bug report.
3529 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3531 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3532 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3534 2006-12-01 Eric Blake <ebb9@byu.net>
3536 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3537 cross-compiling from cygwin to mingw.
3538 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3539 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3540 to lib/autoconf/c.m4.
3542 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3544 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3545 string for more reliable failure. Wrap the entire test that
3546 causes the broken Solaris printf to dump core, in a subshell,
3547 so the segmentation fault message is reliably suppressed.
3548 Fix shell expansion errors by using /usr/ucb/echo always;
3549 avoid an error on systems without it by another subshell.
3550 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3551 subshell-$as_echo to `as_echo', for better error message.
3553 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3555 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3556 `BASH_SOURCE' contain a newline, set them to empty, as they may
3557 not be unset.
3559 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3561 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3562 years and is too hard to maintain now. The last straw was
3563 reported by Jerker Baeck in
3564 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3565 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3566 * doc/autoconf.texi (Particular Functions): Move
3567 AC_FUNC_SETVBUF_REVERSED from here...
3568 (Obsolete Macros): ... to here. Say that it does nothing now.
3569 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3570 Turn into (almost) a no-op.
3572 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3573 (AC_C_VOLATILE):
3574 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3575 These macros are obsolescent and new applications shouldn't need them.
3576 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3577 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
3578 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
3579 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3580 (AC_FUNC_VPRINTF): Likewise.
3581 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3582 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3583 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3585 * doc/autoconf.texi (Setting Output Variables): Mention that
3586 @VAR1@VAR2 has unspecified behavior. Problem reported by
3587 Ralf Wildenhues.
3588 * NEWS: Mention this.
3590 * Makefile.am: Put only a single '#' into the copyright notice,
3591 so that it's also present in the output file. Standardize wording
3592 in makefile copyright notices to match GNU coding standards.
3593 * bin/Makefile.am: Likewise.
3594 * doc/Makefile.am: Likewise.
3595 * lib/Makefile.am: Likewise.
3596 * lib/freeze.mk: Likewise.
3597 * lib/autoconf/Makefile.am: Likewise.
3598 * lib/autoscan/Makefile.am: Likewise.
3599 * lib/autotest/Makefile.am: Likewise.
3600 * lib/m4sugar/Makefile.am: Likewise.
3601 * man/Makefile.am: Likewise.
3602 * tests/Makefile.am: Likewise.
3603 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
3604 one-line file.
3606 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3608 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3609 in the sed script that mangles the awk script: delete up to the
3610 first exclamation mark only.
3611 * tests/torture.at (Substitute and define special characters):
3612 Test '!' too.
3614 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3616 Rewrite config files generation: avoid quadratic growth in
3617 the number of substituted variables by using awk instead of sed
3618 for the bulk of the substitutions.
3619 * NEWS: Mention this.
3620 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3621 forbidden in the output (and thus input) file.
3622 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3623 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3624 generate just one large awk script for substitutions,
3625 eliminating much of the earlier complexity, while adding some
3626 new complexity. Only expand the substitution templates at
3627 configure time, for smaller configure script size. If
3628 _AC_SUBST_FILES are used, test 'awk' for working getline support
3629 at config.status time. If absent, interpolate through the
3630 shell. The awk script was written with much help
3631 from Paolo Bonzini and Paul Eggert.
3632 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3633 (_AC_SED_FRAG_NUM): Likewise.
3634 (_AC_SUBST_CMDS): Renamed from...
3635 (_AC_SED_CMDS): ...this.
3636 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3637 * tests/torture.at (Substitute a 2000-byte string): Also
3638 substitute a line with 1000 words, and a variable with several
3639 long lines.
3640 (Substitute and define special characters): Test awk special
3641 characters, and put substitution input strings `@foo@' in the
3642 output, to test that no recursion happens; test several other
3643 combinations from Paolo Bonzini.
3645 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3647 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3648 that replaced echo with AS_ECHO where this wasn't necessary.
3649 Problem reportd by Ralf Wildenhues.
3650 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3651 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3652 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3654 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3656 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3658 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3660 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3661 that traditional Awk lacks 3-arg "split". It has it.
3662 Mention that FS must be a single character, and a few other
3663 99-byte limits of traditional Awk.
3664 Mention that if (i in a) doesn't work with traditional Awk.
3666 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3668 * tests/autotest.at (BSx641-newline in command):
3669 (BS-BS-newline in command, BSx640-newline in command):
3670 (Newline-CODE-BS-newline in command):
3671 (Single-quote-BS-newline in command):
3672 (Single-quote-newline-BS-newline in command):
3673 Use printf '%s\n' instead of echo, for portability to hosts
3674 where echo interprets backslashes. This will break on hosts
3675 that lack printf, but for now let's assume all such hosts
3676 are dead (if not, we should get reports of test failures).
3678 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3680 'echo' has some portability problems, when given a first argument
3681 with a leading '-', or when given any argument containing '\'.
3682 Avoid using 'echo' in these cases.
3683 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
3684 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
3685 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3686 * lib/autotest/general.m4 (AT_INIT): Likewise.
3687 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
3688 argument might be unportable.
3689 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
3690 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
3691 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
3692 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
3693 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
3694 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
3695 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
3696 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
3697 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.

3703 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
3704 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.

3706 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
3707 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3708 * bin/autoconf.as: Redo verbose flag implementation, as the old
3709 scheme wouldn't work with AS_ECHO.
3710 * lib/autotest/general.m4 (AT_INIT): Likewise.
3711 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3712 Don't use ECHO_T, since ECHO_N is now reliable.
3713 * lib/autotest/general.m4 (AT_INIT): Likewise.
3714 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3715 rather than using a here-document to put the script into a file.
3716 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
3717 use AS_ECHO.
3718 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3719 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3720 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3721 bug, but we might as well stop using ECHO_N and ECHO_C internally.
3722 * lib/autotest/general.m4 (AT_SETUP): Likewise.
3723 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
3724 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3725 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
3726 operand, as AS_ECHO requires. Avoid double file name expansion.
3727 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3728 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3729 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3730 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3731 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3732 Double-quote strings that would otherwise contain M4 comments.
3733 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3735 * configure.ac (AC_INIT): Bump to 2.61a.
3736 * NEWS: Likewise.
3738 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3740 Version 2.61.
3742 * configure.ac (AC_INIT): Bump to 2.61.
3743 * NEWS: Likewise.
3745 * tests/autotest.at (Macro with backslash in a test title):
3746 Comment out for now, as this tests neither fails nor passes
3747 reliably. Problem reported by Ralf Wildenhues.
3749 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3751 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
3752 in previous change, which caused test failures.
3754 2006-11-16 Stepan Kasal <kasal@ucw.cz>
3756 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
3757 code for --enable, --disable, --with, and --without to...
3758 (_AC_INIT_PARSE_ENABLE): ... a new macro.
3759 * doc/autoconf.texi (Package Options):
3760 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
3762 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3764 Import these changes from config via gnulib:
3766 2006-11-15 Ben Elliston <bje@gnu.org>
3768 From Josselin Mouette <joss@debian.org>:

3789 Import this change from gnustandards via gnulib:
3791 2006-11-15 Karl Berry <karl@gnu.org>
3793 * standards.texi: core -> memory, throughout.
3794 (CPU Portability): show correct example of calling write
3795 on a char value; thanks to Paul Eggert for the code.
3796 Both of these suggestions from Eugene Y. Vasserman.
3799 Import these changes from texinfo via gnulib:
3801 2006-11-08 Karl Berry <karl@gnu.org>
3803 * build-aux/texinfo.tex (\dopdfimage): look for png, jpg/jpeg/JPG, and
3804 as well as pdf images, since they are supported in pdftex with
3805 no further ado.

3820 * doc/autoconf.texi (External Software): Document that AC_ARG_WITH's
3821 first argument may also contain dots.
3823 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
3825 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
3826 benefit of platforms like Solaris+GCC where it is common to have a
3827 non-working g++ installation.
3829 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3830 and Joel E. Denny <jdenny@ces.clemson.edu>
3831 and Paul Eggert <eggert@cs.ucla.edu>
3833 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs

3837 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3839 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set

3841 Imported from a similar patch to gnulib by Bruno Haible.
3843 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3845 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
3846 * doc/autoconf.texi (C Compiler): Document them.
3847 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
3848 New macros, taken from gnulib.
3850 2006-11-07 Paul Eggert <eggert@cs.ucla.edu>

3861 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
3862 and Stepan Kasal <kasal@ucw.cz>

3869 argument. Extend to check titles printed by ./micro-suite and
3870 ./micro-suite -l and the title in micro-suite.log.
3871 (Backquote in a test title,
3872 Single-quote in a test title,
3873 Double-quote in a test title): Don't expect failure anymore.
3874 (Backslash in a test title): Put a non-whitespace character after the
3875 backslash so that Bourne shells might actually see it as an escape
3876 sequence.
3877 (Brackets in a test title,
3878 Pound in a test title,
3879 Comma in a test title,
3880 Quoted Macro in a test title,
3881 Macro in a test title,

3885 Macro with backslash in a test title): New tests expected to fail.
3886 * tests/torture.at (#define header templates): M4-quote this title in
3887 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
3888 The visible effect was a stray [] in the testsuite output.
3890 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3892 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
3893 `trap ... 0' inside a function, for AIX sh.
3895 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3897 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3898 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3899 5363) simply issues a warning when dividing by zero at compile
3900 time. Problem reported by Elias Pipping.
3902 2006-10-26 Eric Blake <ebb9@byu.net>
3904 * THANKS: Update.
3905 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3906 show effect on macros that expand with commas.
3907 Reported by Joel E. Denny.
3909 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
3910 Also work with M4 1.4.8.
3912 2006-10-25 Paul Eggert <eggert@cs.ucla.edu>
3914 * doc/autoconf.texi (Slashes): Document Tru64 4.0 bug reported by
3915 Jim Meyering.
3917 2006-10-25 Stepan Kasal <kasal@ucw.cz>

3931 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
3933 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3934 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3935 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3936 reported by Nelson H. F. Beebe for Coreutils 6.4.
3938 * tests/tools.at (autoconf --trace: user macros): Remove test
3939 for tracing multiline macros, since m4 1.4.7a uses a different
3940 way to number lines. Problem reported by Ralf Wildenhues.
3942 2006-10-24 Stepan Kasal <kasal@ucw.cz>
3944 * bin/autom4te.in (handle_m4): Do not redirect stdin to
3945 /dev/null since the heuristics for interactive behaviour was
3946 fixed in CVS m4.
3948 * bin/autom4te.in: With --force, always refresh the output
3949 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
3951 * bin/autoconf.as: Fix the verbose message at the end.
3953 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

3969 AC_CACHE_CHECK_INT, since it's no longer public.
3970 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
3971 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
3973 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3975 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
3977 2006-10-19 Eric Blake <ebb9@byu.net>

3982 m4_mkstemp.
3983 * doc/autoconf.texi (Redefined M4 Macros): Document m4_mkstemp.

3999 2006-10-14 Stepan Kasal <kasal@ucw.cz>
4001 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
4002 looking for special shell characters.
4003 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4004 macro defined by AS_VAR_PUSHDEF before passing it as a
4005 parameter.
4006 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
4007 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

4016 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4018 (Imported from Automake.)
4019 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4020 which incorrectly sets the mode of an existing destination
4021 directory. In some cases the unpatched install-sh could do the
4022 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4023 system. We hope this is rare in practice, but it's clearly worth
4024 fixing. Problem reported by Alex Unleashed in
4025 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4026 Also, don't bother to check for -m bugs unless we're using -m;
4027 suggested by Stepan Kasal.
4029 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4031 Import this change from Automake:
4033 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
4034 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
4035 is enabled by default with gnu and gnits strictness.
4036 Report from Bruno Haible.
4038 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
4039 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
4040 gnu and gnits modes.
4042 Import this change from Config:
4044 2006-09-20 Ben Elliston <bje@gnu.org>
4045 * build-aux/config.sub (score, score-*): New.
4047 Import this change from Gnulib:
4049 2006-09-16 Karl Berry <karl@gnu.org>
4050 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4051 to avoid sectioning errors.
4053 Import these changes from Texinfo:
4055 2006-10-04 Karl Berry <karl@gnu.org>
4056 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
4057 (\quoteexpand): rename to \rquoteexpand.
4058 (\codequoteleft): new def, to look for @set codequotebacktick.
4059 (\lquoteexpand, \quoteexpand): new defs.
4060 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
4061 (\code): must use new \...Char values, since now ` is active.
4063 2006-08-26 Karl Berry <karl@gnu.org>
4064 * build-aux/texinfo.tex (\textdegree): New command.
4066 2006-08-12 Karl Berry <karl@gnu.org>
4067 * build-aux/texinfo.tex (error \box0): smaller font.
4069 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4071 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
4073 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4075 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4076 added to the template can get mangled.
4078 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4080 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4081 include the default headers, and redefine obstack_chunk_alloc
4082 and obstack_chunk_free. Fixes false failure with glibc.
4084 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4086 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
4087 for backward compatibility with Libtool 1.5.22. Problem reported
4088 by Ralf Wildenhues.
4090 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4092 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
4093 AC_PROG_CC.
4094 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
4096 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4098 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
4099 the NonStop platform.
4100 * doc/autoconf.texi (Posix Variants): Likewise.
4101 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4103 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4104 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4105 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4106 Use a better substitute, by inspecting the output of "ls"
4107 rather than just using ":".
4108 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4109 rather than AS_EXECUTABLE_P, since we needn't worry about
4110 non-regular files here.
4112 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4113 due to configuration hassles with this. See Tonya Underwood's report
4114 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
4115 * doc/autoconf.texi (Special Shell Variables): Likewise.
4117 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4118 Stepan Kasal <kasal@ucw.cz>

4121 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
4123 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4125 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4126 initialization which is not inherited through the environment
4127 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4128 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4130 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4132 * doc/autoconf.texi (Limitations of Usual Tools): Describe
4133 problems with mkdir -p -m.
4135 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4137 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4138 comment about ac_cpp_err; it was incorrect, and anyway
4139 ac_cpp_err is being removed below.
4140 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4141 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4142 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4143 nobody uses it.
4144 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4145 with werror_flag and conftest.err and so forth. This is more
4146 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4147 and anyway the user shouldn't normally want to see this gorp logged.
4148 Problem reported by Ralf Wildenhues.
4149 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4150 empty, not 'no', since the rest of the code uses 'test -z'.
4152 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4154 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4155 Use a single call to AC_DO_TOKENS rather than multiple, for
4156 efficiency.
4157 (_AC_LINK_IFELSE): Test that resulting file is executable.
4158 Problem reported by mwoehlke in
4159 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4161 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4162 than creating a file to use with test -x; this is much faster.
4164 2006-10-02 Bruno Haible <bruno@clisp.org>
4166 * lib/autom4te.in (Automake-preselections): Add
4167 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4169 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4171 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4172 standard error, `experr' should be used, not `expout'.
4174 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4176 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4177 fseeko testing program twice; just use the earlier result.
4178 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4179 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4180 still doesn't let the program compile.
4181 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4182 failed.
4184 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4185 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4186 include it, without including anything else.
4187 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4188 expressions.
4189 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
4191 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4193 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4194 `error.h', and include it, for a `error_at_line' prototype.
4195 Use a nonempty format string in the link test.
4196 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4197 for a declaration of wait3.
4199 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4201 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
4202 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
4203 can apply to constants too, and that it checks for macro defns.
4204 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
4205 and simply cast the identifier to void. This handles structure
4206 values. Problem reported by Ralf Wildenhues.
4207 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
4209 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4212 structure, and function symbols.
4214 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4216 * tests/semantics.at (AC_CHECK_MEMBERS): Also test with a struct
4217 member.

4306 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
4307 works with GNU M4 1.4.3 again; make the normalized form
4308 match the current m4 message; fix the description.

4317 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
4318 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
4319 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
4320 assume C89.

4342 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
4343 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
4344 accept files with extension `.f'. For consistency, also prefer
4345 xlf over f77.
4346 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
4347 from last patch.

4418 deal with LEXLIB.
4419 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
4420 didn't work if some values were cached but not others. Test for
4421 broken lex libraries like native ia64-hp-hpux11.22; see
4422 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
4423 work around the problem by preferring an empty LEXLIB to -lfl or
4424 -ll. Let the user set LEXLIB='' to indicate no library needed.
4426 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
4427 * README: Likewise.

4656 reported by Keith Marshall. Also, don't bother with builddir2,
4657 since it shouldn't be needed any more.
4659 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

4685 that long long int is 32 bits wide with some nonstandard compilers.

4688 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
4690 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4691 to a nonexistent file, so that we don't have to worry about
4692 a local site configuration that doesn't use /usr/local.

4696 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4698 * doc/autoconf.texi: Be more consistent about using @acronym with
4699 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4700 quite right (it talked about "OSF/Tru64", even though the
4701 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4702 and it even mentioned "OSF 4"!) and at this point there's little
4703 reason to talk about OSF any more, since it died in 1994.
4704 (Specific Compiler Characteristics): Simplify example of
4705 negative-size array.
4706 (File Descriptors): Reorder to make the text flow better.
4707 Remove joke about "appreciate the various levels"; I didn't get it.
4708 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4709 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4710 (File Descriptors, Limitations of Usual Tools):
4711 Tone down the advice against renaming or removing open files.
4712 (Limitations of Usual Tools): Add a new section, on 'rm'.
4714 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4716 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4717 -lXt in LIBS, idea from Karsten Hopp; this was due since
4718 this change:
4720 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4721 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4722 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4723 (which belong to Xt, not X itself). See Debian bug 327655.
4725 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4727 * configure.ac (AC_INIT): Bump to 2.60a.
4728 * NEWS: Update.
4730 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4732 Version 2.60.
4734 * configure.ac, NEWS: Update.
4736 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4738 * config/texinfo.tex: Sync from upstream.
4740 * bin/autom4te.in (handle_traces): Transform the `@S|@'
4741 quadrigraph correctly in traces.
4743 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
4744 Fix typos.
4746 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
4747 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4748 not defined.
4749 * doc/autoconf.texi (Changed Directory Variables): New node,
4750 to document the whole `datarootdir' business a bit better.
4751 * NEWS: Update.
4752 * tests/torture.at (datarootdir workaround): Extend test.
4753 Prompted by report by Alexandre Julliard.
4755 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4757 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4758 when using default mode of IBM C 6 for AIX. Problem and two-line
4759 fix reported by Larry Jones.
4761 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4763 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4764 about literal '${datarootdir}' if a definition is found in the
4765 output file.
4767 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4769 * NEWS: Use "M4" rather than "m4" when appropriate.
4770 Problem reported by Eric Blake.
4771 * doc/autoconf.texi: Likewise.
4772 Use @acronym around BSD, GCC, and GNU when appropriate.
4773 (Why GNU M4): Renamed from "Why GNU m4".
4774 (Redefined M4 Macros): Mention that Posix
4775 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4776 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4777 to int.
4779 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4781 * bin/autom4te.in (handle_output): Do not forbid the empty
4782 pattern.
4783 * tests/tools.at (autoconf: the empty token): New test.
4785 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4787 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4788 calls, so that we do not care whether they are LIFO or FIFO;
4789 in the m4_wrap, do not check which diversion is the topmost
4790 one, just check that the stack is balanced at the end.
4791 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4792 base diversion forever--pop the previous diversion before
4793 opening the new one; consequently, remove the m4_wrap call.
4794 * lib/autotest/general.m4 (AT_INIT): Likewise.
4795 * tests/m4sugar.at: Do not use
4796 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
4798 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
4799 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4801 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4802 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4803 Rework example of m4wrap token-pasting trouble so that it doesn't
4804 care whether it's LIFO or FIFO.
4805 Fix some "contrary to"s that are awkward in English.
4807 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4809 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4810 to `yes' instead of `int$1_t' if the type is found, for more
4811 consistent configure output (where $1 is the number of bits).
4812 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4813 Suggested by Bruno Haible.
4815 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4816 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4817 with system headers. Report by Bruno Haible.
4819 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4821 * config/config.guess, config/config.sub: Sync from upstream.
4823 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4824 in order to avoid picking up an older installed frozen m4sh.m4f.
4825 Besides an outdated shell startup, this could have been created
4826 by an earlier M4 version with incompatible frozen file format.
4828 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4830 * README: Recommend m4 1.4.4 instead of 1.4.3..
4831 * doc/autoconf.texi: Likewise.
4832 (Special Chars in Names): Say that $(.FOO) is portable, as
4833 suggested by Stepan Kasal.
4834 (Installation Directory Variables, Build Directories):
4835 (Automatic Remaking, Subdirectories, Fortran Compiler):
4836 (Making testsuite Scripts, Defining Directories):
4837 Quote variable usages better.
4838 (Making testsuite Scripts): Add clean-local rule to makefile
4839 snippet, by Eric Blake.
4840 (Installation Directory Variables): Fix table item font.
4841 Reword slightly to clarify. Generalize advice about
4842 not using special characters to include all file-related
4843 vars, not just VPATH.
4844 (Special Chars in Variables): Warn about special characters in
4845 $(srcdir) too.
4846 (Assignments): Clarify default-value example as suggested by
4847 Ralf Wildenhues in
4848 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4849 (Special Shell Variables): Note leading ./ or ../, as suggested
4850 by Eric Blake.
4851 (Limitations of Builtins): Under cd, warn about CDPATH.
4852 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4853 Ralf Wildenhues.
4855 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4857 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4858 `@var', for texi2html.
4859 (Systemology): Some more word wrapping, for DVI output.
4860 (autom4te Invocation): The short option for `--melt' is `-M',
4861 not `-m'.
4863 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4865 * doc/autoconf.texi: More formatting and English tweaks,
4866 many suggested by Ralf Wildenhues.
4867 Reword to avoid "@code{...}'s" and the like, since it's ugly
4868 with Emacs info mode. discontents -> woes.
4869 Put a few "will"s back. time stamp -> timestamp.
4870 side-effect -> side effect.
4872 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4874 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4875 Warn about $@ not persisting. Problem reported by Julien Danjou in
4876 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4877 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4878 Mention other special chars, too.
4880 2006-06-14 Eric Blake <ebb9@byu.net>
4882 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4884 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4886 * doc/autoconf.texi: Some systematic minor improvements, as
4887 follows. Use "makefile" when talking about makefiles
4888 generally (which might be named "makefile" or "Makefile" or even
4889 "foo.mk"), "Makefile" when talking about a specific makefile
4890 called "Makefile". This unclutters the text from weird quotes
4891 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4892 values" rather than "@var{foo}s" and similar constructs containing
4893 "}s". Use "Make rules" rather than "Makefile rules". Minor
4894 English-language improvements. Change the prefix "sub-" to "sub"
4895 and "re-" to "re".
4896 Put blank lines around examples more consistently.
4897 Avoid "rather" and "very" as intensifiers.
4898 Avoid "will" as an auxiliary.
4899 (Limitations of Make): Split this node into....
4900 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4901 (Leading _ in Macro Names, Backslash-Newline-Newline):
4902 (Backslash-Newline Comments, Long Lines in Makefiles):
4903 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4904 (obj/ and Make, make -k Status, VPATH and Make):
4905 (VPATH and Double-colon, $< in Explicit Rules):
4906 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4907 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4908 New nodes, resulting from splitup of Limitations of Make.
4909 All cross-references changed. Raise the top node from
4910 a section to a chapter, and all subnodes accordingly.
4911 Redo the introductory wording to match the new organization.
4912 (Installation Directory Variables): Use an example that is
4913 closer to what Autoconf actually does. Mention that VPATH's
4914 value should not contain metacharacters or white space.
4915 (Fortran Compiler): Fix a VPATH bug in an example.
4916 (Leading _ in Macro Names): Mention that this problem is no longer
4917 of practical concern.
4918 (VPATH and Make): Reword the advice to make it clearer
4919 that Autoconf and Automake support VPATH in non-GNU make, but
4920 many packages have bugs in this area.
4921 ($< in Explicit Rules): Refer to Build Directories rather
4922 than using a (non-VPATH-safe) example.
4923 (Automatic Rule Rewriting): Mention the sort of disaster that
4924 can ensue with Solaris-style rule rewriting with VPATH.
4926 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4928 * doc/install.texi (Compilers and Options): Weaken the
4929 suggestion to use GNU make for VPATH builds.
4931 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4932 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4934 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4935 in regular expression.
4937 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4939 * doc/autoconf.texi (Installation Directory Variables):
4940 Drop extra @samp from `@table @samp' item.
4941 (Limitations of Usual Tools): Comment fix.
4942 Do not nest @samp just to point to other table items.
4943 (Writing testsuite.at) <AT_CHECK>: The second argument to
4944 `@dvar' is already @samp'ed.
4945 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4946 do not use @var in the second argument.
4948 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4950 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4951 $as_shell.exe too. Problem reported by Andreas Buening in
4952 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
4954 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4956 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4957 `unused variable' compiler warning, for `-Wall -Werror'.
4958 Reported by Jaap Haitsma in
4959 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4961 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
4963 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4964 case the compiler dumps core. Problem reported for
4965 OpenServer 5.0.7 by Tim Rice in
4966 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
4967 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4968 Likewise.
4970 2006-06-06 Tim Rice <tim@multitalents.net>.
4972 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
4973 "ERROR" only shows up in "make check" output if there is an
4974 error.
4976 2006-06-06 Eric Blake <ebb9@byu.net>
4978 * tests/tools.at (automatically allowed tokens): Fix typo.
4980 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4982 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
4984 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
4985 typically overflows on x86 CPUs, even though the C standard
4986 requires otherwise.
4988 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4990 * configure.ac (AC_INIT): Bump to 2.59e.
4991 * NEWS: Update.
4993 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4995 Version 2.59d.
4997 * config/texinfo.tex: Sync from upstream.
4999 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5000 seen, invoke libtoolize with `--ltdl' argument.
5001 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5002 * NEWS: Update.
5003 Suggested by Eric Blake.
5005 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5007 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5008 reported by Ralf Wildenhues.
5009 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
5011 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5013 * THANKS: Update.
5015 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5017 * doc/autoconf.texi: Modernize some of the references to Solaris.
5019 2006-06-05 Stepan Kasal <kasal@ucw.cz>
5021 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5022 message issued by AC_REQUIRE.
5023 * tests/m4sugar.at: Check m4_require's error message.
5024 * tests/base.at: Check AC_REQUIRE's error message.
5025 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5026 to...
5027 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5028 AT_CHECK_M4.
5029 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5030 `expout' as the last parameter.
5031 * tests/tools.at: Adapt to the above change.
5033 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5035 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5036 information about race-free implementations of mkdir.
5038 2006-06-04 Eric Blake <ebb9@byu.net>
5040 * bin/autoreconf.in (help): Document M4 environment variable.
5041 * bin/autoconf.as (Usage): Likewise.
5042 * bin/autom4te.in (help): Likewise.
5043 * doc/autoconf.texi (autom4te Invocation): Likewise.
5045 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5047 * NEWS: GNU make now recommended for VPATH builds.
5048 Mention that some macros are now documented to be obsolescent.
5049 * doc/autoconf.texi:
5050 Prefer "current" to "modern" to describe
5051 currently-used (albeit perhaps old-fashioned) hosts.
5052 Mention which ancient features no longer need to be worried about.
5053 setgid -> set-group-ID
5054 setuid -> set-user-ID (these are the Posix terms)
5055 Fix some misuses of "only".
5056 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5057 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5058 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
5059 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
5060 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
5061 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
5062 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
5063 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
5064 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
5065 Mention that these macros are obsolescent.
5066 (Installation Directory Variables): shall -> should
5067 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5068 Mention that it's now safe to use 3 and 4.
5069 (Limitations of Usual Tools): cp -r is now specified by Posix.
5070 Omit longwinded and obsolescent discussion of cp -f.
5071 Modernize discussion of expr, ls.
5072 (Limitations of Make): Modernize discussion of VPATH builds.
5073 Mention $? as a workaround in some cases.
5074 * doc/install.texi (Basic Installation):
5075 Mention "./configure; make; make install" first. Be more
5076 specific about why this file is generic. Remove unnecessary
5077 parens. Remove misleading "only". Remove obsolete advice
5078 about csh. Don't say "configure" takes awhile; say it
5079 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5080 and CC=c99 rather than CC=c89, as these are blessed by current
5081 Posix. Recommend GNU make if doing a VPATH build.
5083 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5085 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5086 examples involving shell prompts.
5088 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5089 and Paul Eggert <eggert@cs.ucla.edu>
5091 * doc/autoconf.texi (Here-Documents): Add details about the
5092 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5093 use "here-documents" instead of "here documents".
5095 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5097 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5099 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5101 * doc/autoconf.texi (File System Conventions): Warn about ":"
5102 anywhere in directory names.
5104 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5106 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5107 about quoting the case statement, just in case.
5108 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5109 was fixed in ksh93g; reported by Ralf Wildenhues.
5111 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5113 * doc/autoconf.texi (System Services): Do not document
5114 overriding EXEEXT via ac_cv_exeext=ext.
5115 (Particular Programs) <AC_PROG_MKDIR_P>:
5116 Document that ${MKDIR_P} understands --.
5117 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5118 comment.
5120 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5122 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5123 argument with leading hyphen. Problem reported by Paul Eggert.
5125 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5127 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5128 about quoting ac_try: quote all of it, if any of it seems suspicious.
5129 This means we don't have to worry about ${ or sed any more.
5130 Also, double-quote the case statement, to work around misuses via
5131 underquoting as reported by Ralf Wildenhues in
5132 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5133 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5134 undocumented and dangerous macro.
5135 Problem reported by Ralf Wildenhues in
5136 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5138 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5140 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5141 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5142 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5144 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5146 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5147 since evidently some packages rely on the old, broken behavior.
5148 Problem reported by Ralf Wildenhues in
5149 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5150 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5151 pre-2006-05-26 definitions, but leave in the comments that
5152 these macros are dangerous and should not be used.
5153 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5154 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5155 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5156 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5157 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5159 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5161 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5162 the use of 'tr', since this is our only use of 'tr'.
5164 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5165 and Paul Eggert <eggert@cs.ucla.edu>
5167 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5168 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5170 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5172 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5173 the output file in the `${datarootdir}' test.
5175 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5176 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5178 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5179 mention of `datarootdir' in the input file(s), but literal
5180 `${datarootdir}' in the output file, and we haven't warned yet,
5181 then warn as well: the user may have (erroneously) used
5182 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5183 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5184 * tests/torture.at (datarootdir workaround): Extend this test.
5185 * NEWS: Update.
5187 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5188 and Paul Eggert <eggert@cs.ucla.edu>
5190 * doc/autoconf.texi (autoheader Invocation): The first argument to
5191 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5192 alternatives and clear up the language a bit.
5194 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5196 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5197 ac_config_guess, ac_config_sub, ac_configure.
5198 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5199 Fix typo that prevented an unnecessary space from being removed.
5200 Problems reported by Ralf Wildenhues in:
5201 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5203 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5205 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5206 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5207 Don't use the term "thread-safe" to talk about mkdir race
5208 conditions, since the problem is more a process than a thread
5209 issue. Problem reported by Stepan Kasal in:
5210 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5211 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5212 the test for 'install' more closely. Look at MKDIR_P first.
5213 Look in the PATH, and at /opt/sfw/bin.
5214 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5215 Don't bother to try mkdir -p, since we already check mkdir --version;
5216 just look at the version number. (There's no easy way to check
5217 for race-free implementations.)
5218 * tests/tools.at (autoconf: subdirectories): Adjust to above
5219 changes, since MKDIR_P now might end in "/mkdir -p".
5221 * doc/autoconf.texi (autoheader Invocation): Mention that the
5222 first arg of AC_DEFINE_UNQUOTED must be a literal.
5223 Problem reported by Ben Pfaff in
5224 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5226 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5227 * doc/autoconf.texi (Special Chars in Variables): New section.
5228 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5229 (Installation Directory Variables): Quote $(datadir) better.
5230 (Limitations of Builtins): Describe some of eval's trickiness.
5232 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5233 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5234 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5235 in front of every arg, not just trailing args. Quote apostrophes.
5236 (_AC_EVAL_ECHO): New macro.
5237 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5238 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5239 removed.
5240 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5241 exposed by quoting of eval argument. Put the command on line line
5242 so it logs better.
5243 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5244 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5245 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5246 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5247 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5248 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5249 Use eval more safely.
5250 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5251 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5252 to be replaced.
5253 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5254 lines, exposed by quoting of eval argument.
5256 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5257 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5259 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5260 initialization of `ac_cv_exeext', do not override it if it was
5261 already set, unless it was set to `no', for compatibility with
5262 Autoconf-2.13, and comment this.
5263 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5264 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5265 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5266 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5267 Document that this test may be overridden by setting
5268 `ac_cv_exeext'.
5270 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5272 Revert these two patches:
5274 2006-04-06 Eric Blake <ebb9@byu.net>
5275 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5276 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5277 2006-04-01.
5279 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5280 Clean up _AC_COMPILER_EXEEXT* macros.
5281 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5282 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5283 ac_file to the name of the default output file and call
5284 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5285 initial `rm' of the candidate files...
5286 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5287 the same list in subsequent `rm' calls, and for the temporary
5288 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5289 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5290 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5291 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5292 no longer needed) by libtool. Make it a cache check.
5293 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5294 copied here by mistake.
5295 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5296 _AC_COMPILER_EXEEXT.
5297 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5298 _AC_COMPILER_OBJEXT directly.
5299 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5301 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5303 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5304 Fix description of how the buggy `sed' works.
5306 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5308 Sync from Automake:
5310 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5311 ENOLCK. Only mention `make -j' when applicable. Only raise
5312 fatal errors when `make -j' is involved. Improve error message.
5314 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5316 * doc/autoconf.texi (Here-Documents): We now know more about
5317 the variable expansion in here documents bug.
5318 Thanks to Tim Rice and Stepan Kasal.
5320 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5321 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5323 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5325 * tests/autotest.at (Multiline command from M4 expansion):
5326 No failure to be expected if the shell quotes newlines in
5327 commands in the `set -x' output. Report by Tim Rice.
5328 * THANKS: Update.
5330 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5332 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5333 expansion in the here-documents used by config.status, as that
5334 runs afoul of the Korn shell version M-12/28/93d bug described in
5335 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5336 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5337 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5339 2006-05-23 Jim Meyering <jim@meyering.net>
5341 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5342 Fix typo introduced with 2006-04-02 change. It reversed the sense
5343 of the test.
5345 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5347 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5348 ac_dB slightly, to save bytes in the script.
5349 Max out at 50 lines, rather than 96; this is more likely
5350 (though not guaranteed) to avoid obscure 'sed' failures.
5352 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5354 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5355 `tr -d -' as bad option argument. Work around this by deleting
5356 an unrelated character.
5357 Report by Tim Rice <tim@multitalents.net>.
5359 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5360 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5361 Stepan Kasal <kasal@ucw.cz>
5363 * doc/autoconf.texi (Particular Programs): Do not promise that
5364 we always prefer the GNU version of the program, and that we
5365 search according to PATH; both rules can have exceptions.
5366 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5367 AC_PROG_SED. Move descriptions of limitations
5368 to the Limitations of Usual Tools section.
5369 (Limitations of Usual Tools) <sed>: Mention script length
5370 limitations with Solaris /usr/ucb/sed.
5371 <grep>: Fix wording for empty alternative. Mention that -c and
5372 -l should not be combined, and that -E and -F should not be
5373 combined.
5375 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5376 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5378 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5379 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5381 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5383 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5384 AC_DEFINE is now passed to m4_pattern_allow.
5385 * NEWS: Mention that; likewise for AC_SUBST.
5386 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5387 the parameter to m4_pattern_allow.
5388 * tests/tools.at: Add a check for that.
5390 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5392 * lib/autoconf/status.m4: Fix typos.
5394 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5396 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5397 only the files that this macro generates.
5399 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5401 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5402 the HP-UX sed limitation of 99 commands, labels do not count.
5403 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5404 in the comment.
5405 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5407 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5409 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5410 Import the following fix from coreutils:
5412 2006-01-13 Jim Meyering <jim@meyering.net>
5414 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5415 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5416 not double-quote uses of that variable, to accommodate the rare
5417 case in which getmntent is available in none of the libraries
5418 checked. This happens at least on FreeBSD 5.0.
5420 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5422 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5423 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5424 some other programs unwisely rely on these undocumented vars.
5425 But put in warning comments about them.
5426 Problem reported by Ralf Wildenhues in
5427 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5428 * NEWS: Document that these variables are intended to go away.
5430 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5432 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5433 and set the language to C++ (analogous to the equivalent Fortran
5434 tests).
5436 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5437 * doc/autoconf.texi (C++ Compiler): Document it.
5438 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5439 * NEWS: Update.
5441 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5443 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5444 that caused config.status to generate 100-command sed scripts; the
5445 portable limit is 99.
5447 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5449 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5450 variable `ac_d' instead of `d' to avoid infringing namespace.
5451 Report by Ralf Menzel.
5453 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5455 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5456 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5457 * tests/tools.at (autoconf: subdirectories): New test, taken from
5458 the corresponding problem report by Ralf Wildenhues in:
5459 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5461 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5462 Quote some uses of shell variables if they might suffer unexpected
5463 globbing. This doesn't fix all instances of quoting problems that
5464 I found, just the easy ones that look safe.
5465 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5466 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5467 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5468 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5469 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5470 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5471 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5472 Likewise.
5473 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5474 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5476 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5478 * bin/autoreconf.in ($help): Reword according to the manual.
5479 Suggested by Olly Betts.
5481 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5482 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5484 * bin/autoreconf.in: Pass the directory argument to
5485 `require_configure_ac'. Fix comment.
5486 * tests/torture.at (Configuring subdirectories): Expose this.
5487 Reported by Olly Betts.
5489 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5491 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5492 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5493 Automake as follows:
5495 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5496 `$configure_in' instead of `configure.in', to preserve
5497 directory component.
5499 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5501 * config/config.guess, config/config.sub, config/texinfo.tex,
5502 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5504 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5506 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5507 test for C99 conformance; (bool) 0.5 is an integer constant
5508 expression, but (bool) -0.5 is not. Problem reported by Fedor
5509 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5511 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5513 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5514 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5515 Warn about obsolete install-sh files. Remove stray sentence
5516 fragment and fix cross reference.
5517 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5518 install -d; this undoes the 2006-05-10 change.
5519 (MKDIR_P): Mark with AN_MAKEVAR.
5520 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5521 that we don't require $INSTALL to be thread-safe. Move comments
5522 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5523 of AC_PROG_INSTALL. Output a message saying that we're checking
5524 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5525 MKDIR_P instead of AC_SUBST.
5526 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5527 Special magic for MKDIR_P, too.
5528 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5529 a dnl.
5530 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5532 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5534 Sync from Automake, as follows:
5536 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5537 * config/install-sh: Initialize IFS, so field splitting isn't
5538 turned off later.
5539 * config/mkinstalldirs: Likewise.
5540 * config/missing: Remove superfluous quotes. Replace all uses of
5541 `[' by `test', for consistency, and for..
5542 * config/missing (sed_minuso, sed_output): New variables.
5543 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5544 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5545 Fixes `missing' to detect `--output' for help2man. Fixes
5546 PR automake/483. Report by Dennis J. Linse.
5547 (autom4te): Document in `missing --help'.
5549 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5551 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5552 * config/install-sh: Don't use 'path' to talk about file names,
5553 as per GNU coding standards. Close a race condition reported by Ralf
5554 Wildenhues and Stepan Kasal. There is still a race condition
5555 on hosts that predate Posix 1003.1-1992, but we can't help this.
5556 Don't mishandle weird characters like space on pre-Posix hosts.
5557 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5558 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5559 AC_PROG_MKDIR_P from AS_MKDIR_P.
5560 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5561 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5562 earlier editions are not (including Automake 1.8.3).
5563 Do not suggest mkinstalldirs for thread-safety.
5564 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5565 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5566 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5567 presence of special characters and race conditions.
5568 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5569 in Autoconf's name space.
5571 2006-05-10 Bruno Haible <bruno@clisp.org>
5572 and Paul Eggert <eggert@cs.ucla.edu>
5574 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5575 from Automake with minor changes.
5576 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5578 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5580 * config/install-sh: Update to Automake CVS version, as follows:
5581 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5582 * lib/install-sh: Simplify the expr implementation of dirname.
5583 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5584 * lib/install-sh: Handle --, and diagnose unknown options.
5586 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5588 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5589 `./autom4te' to create `./testsuite', since the `all' target
5590 will ensure its presence, but `installcheck' should not create
5591 the uninstalled wrappers.
5593 * tests/torture.at (Unusual Automake input files): Skip if we
5594 detect automake < 1.8.
5596 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5598 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5599 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5600 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5601 * NEWS: Update.
5603 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5605 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5606 munge (multiple) white space and other oddities.
5607 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5608 single quotes in variable assignment.
5609 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5610 and similar failures by adding multiple spaces, tabs, and other
5611 special characters.
5612 Report and different test suggested by Francesco Romani
5613 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5615 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5616 single quotes, we only need to search for single quotes; this
5617 both simplifies the search pattern, and makes us less
5618 susceptible to `echo' variations for arguments not containing
5619 single quotes.
5620 (_AC_ARG_VAR_VALIDATE): Likewise.
5622 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5624 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5625 `$*' and IFS concatenation issue with traditional shells and
5626 bash-2.04. Report by Seanster@Seanster.com.
5628 2006-05-03 Bruno Haible <bruno@clisp.org>
5630 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5631 precisely which Mac OS X versions have the od problem.
5633 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5635 * doc/autoconf.texi: Use @option systematically.
5637 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5638 and Bruno Haible <bruno@clisp.org>
5640 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5641 about 'od'.
5642 (Integer Overflow): Mention the special case of integer division
5643 overflow.
5645 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5647 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5648 traditional shells like the Solaris one that do not use the
5649 first IFS character for assembling `$*'.
5650 Prompted by a related report from autoconf_bug@nro.ca.
5652 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5653 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5655 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5656 Mention more problems with the -e option.
5658 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5660 * NEWS: Typo.
5661 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5663 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5664 in URLs to improve DVI formatted output (requires texinfo 4.6).
5665 (System Services, Systemology, Shellology): Likewise.
5666 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5667 output.
5669 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5670 continuous text.
5671 (Runtime): Fix macro argument names to match description:
5672 `action-if-found' -> `action-if-true' and similarly.
5673 (Obsolete Macros): Likewise.
5674 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5675 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5676 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5678 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5680 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5682 * ChangeLog: Typo.
5683 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
5684 DVI output.

5693 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
5695 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
5696 (Integer Overflow, Null Pointers, Buffer Overruns):
5697 (Floating Point Portability, Exiting Portably): New sections.
5698 (Writing Test Programs): Fix some langauge. Recommend exiting
5699 with status 1, not merely nonzero. Clarify exit declaration.
5700 (Run Time): Move C exit status stuff to new Exiting Portably section.
5701 (Systemology): Mention Posix and levenez. Update v7 reference.
5702 (Portable Shell): Mention the Posix shell.
5704 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5706 * bin/autoconf.as (me): Replace by as_me.
5708 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5710 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5711 since as_me isn't set yet.
5713 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5715 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5716 a few minor bugs in this area.
5718 * doc/autoconf.texi (Programming in M4sh): Comment out the
5719 documentation of AS_BASENAME, for now.
5720 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5721 (Limitations of Builtins) <basename>: Do not refer to
5722 AS_BASENAME.
5723 * bin/autoconf.as (me): Don't use AS_BASENAME.
5724 (dir): Remove the unused variable.
5725 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5726 AS_DETECT_REQUIRED. All uses changed.
5727 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
5728 All uses changed.
5729 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
5730 (AS_BASENAME): Use "basename --" to protect against leading "-".
5731 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
5732 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
5733 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
5734 (_AS_DIRNAME_PREPARE): Likewise.
5735 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
5736 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
5737 (AS_DIRNAME): Use "dirname --".
5739 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5741 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5742 of "run time" and "run-time" changed to "runtime", for consistency.
5743 * lib/autoconf/fortran.m4: Likewise (in comment).
5744 * lib/autoconf/functions.m4: Likewise.
5745 * lib/autoconf/general.m4: Likewise.
5746 * lib/autoconf/headers.m4: Likewise.
5748 * doc/autoconf.texi (Run Time): Document the exit status situation
5749 with more accuracy and detail.
5751 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5753 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5754 Archive is not officially `GNU' any more. Update URL.
5755 (Defining Directories): Likewise
5756 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5758 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5760 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5761 newline from the `trap' code to finish `config.log'; the NetBSD
5762 /bin/sh resets the exit status after an empty command, as
5763 documented in doc/autoconf.texi.
5764 Reported by Dalibor Topic <robilad@kaffe.org>.
5766 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5768 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5769 Suggested by Bruno Haible.
5771 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5773 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5774 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5775 Instead, just list the shells that we know work.
5776 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5777 changed. Be more cautious about the _cv_ variable.
5778 * tests/tools.at (Syntax of the shell scripts): Check the
5779 _cv_ variable once, at first, to avoid an internal autoconf error
5780 when sh -n does not work.
5782 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5784 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5786 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5788 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5789 use ">&-" since we're only 99.999% sure that this is portable,
5790 and since the MinGW bug is fixed in a different way.
5791 * lib/autotest/general.m4 (AT_INIT): Likewise.
5793 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5795 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5796 before opening config.log, to avoid hitting a bug on MinGW.
5798 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5800 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5801 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5802 This works around a MinGW bug reported by Eric Paire.
5803 Make sure that all writes to the log file append to it,
5804 rather than possibly losing data.
5805 * lib/autotest/general.m4 (AT_INIT): Likewise.
5807 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5809 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5810 description.
5812 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5814 * NEWS: Update.
5816 * configure.ac (AC_INIT): Bump to 2.59d.
5818 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5820 Version 2.59c.
5822 * Makefile.maint (news-date-check): Do not require a leading `*'
5823 before the release date in NEWS.
5825 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5826 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5828 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5829 the instantiated file do not contain the string 'datarootdir'
5830 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5831 @mandir@, replace the reference '${datarootdir}' by the value.
5832 * tests/torture.at (datarootdir workaround): New test.
5833 * NEWS: Advertise this temporary fixup.
5834 Based on a patch by Bruno Haible, reported and analyzed by
5835 Paul Eggert and Noah Misch.
5837 2006-04-12 Eric Blake <ebb9@byu.net>
5839 * tests/autotest.at (Debugging a failed test): Fix comment.
5841 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5843 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5844 all the changes since 2006-04-07.
5846 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5848 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5849 succeeded, but `ln -s file dir' failed, take care to remove the
5850 leftover target before the next test, to prevent its spurious
5851 failure; also make sure `ln file dir' works before selecting it.
5852 Thanks to Keith Marshall for pointing this out.
5853 * THANKS: Update.
5855 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5856 assignments in `at_debug_args', so that we put them correctly
5857 in the `run' script.
5858 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5859 Reported by Eric Blake.
5861 2006-04-11 Eric Blake <ebb9@byu.net>
5863 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5864 top-level tests after micro-suite has been run. Used in...
5865 (Debugging a successful test, Debugging script and environment),
5866 (Debugging a failed test): ...these new tests. The first of these
5867 is fixed by...
5868 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5869 macro, split out from...
5870 (AT_INIT): ...here, so that using -d also generates a run script.
5871 Document that -d inhibits top-level logging.
5872 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5873 inhibits top-level logging; debug scripts are created.
5875 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5876 check.
5877 * tests/autotest.at (Empty test, Empty check): New test to check it.
5879 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5880 from gcc.
5882 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5884 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5885 the files if a problem appears. Make the empty *.at files
5886 read-only, too. Proposed by Ralf Wildenhues.
5888 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5890 * config/Makefile.am: Add comment to force updated Makefile.in.
5892 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5893 space only patch to this file, this patch causes the Makefile.in
5894 files that include freeze.mk to be updated, and thus have a
5895 newer time stamp again, which in turn makes a pristine CVS
5896 checkout have correct time stamps.
5898 * Makefile.maint (cvs-sv): New macro, to be used..
5899 (config.guess-url_prefix, config.sub-url_prefix)
5900 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5901 point to CVS text checkout of Gnulib files.
5902 (copyright-check): Bump current year.
5903 (announcement): Do not hard-wire `./announce-gen'.
5904 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5905 correctly.
5906 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5907 `chmod +x'.
5908 (wget_files): Update config.guess, config.sub, texinfo.tex by
5909 `wget-update', now that their URLs work again.
5911 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5913 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5914 Problem noted by Paul D. Smith.
5916 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5918 * doc/autoconf.texi: Remove unused words from word list.
5919 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5920 .x-sc_trailing_space: New files.
5922 * doc/standards.texi: Sync from gnulib.
5924 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5925 `LIBOBJDIR' as experimental.
5927 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5928 with a target directory; it's internally implemented as `cp'
5929 anyway, but since Autoconf advertises the possibility to use
5930 a target directory when LN_S is `ln -s', we need to find out.
5931 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5932 analyzed by Keith Marshall <keith.marshall@total.com>.
5934 * THANKS: Update.
5936 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5938 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5939 confdefs.h as-is. In general, if it has backslash-newline or the
5940 like, then it doesn't work either to sort or to remove empty
5941 lines.
5943 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5945 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
5947 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
5949 * lib/autom4te.in (Automake-preselections): Preselect
5950 _AM_SUBST_NOTMAKE.
5952 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5954 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5955 apostrophe within a single-quoted string, as this is the usual
5956 tradition and is easier to read than '"'"'. Don't rely on the
5957 shell treating "$/" like '$/'. Use a more-consistent indenting
5958 style for the trap.
5960 2006-04-09 Eric Blake <ebb9@byu.net>
5962 * tests/autotest.at (Backquote command substitution),
5963 (Multiline backquote command substitution): Remove mistaken
5964 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
5965 applied...
5966 (Parenthetical command substitution, Multiline parenthetical
5967 command substitution): here.
5969 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5971 Import macros from gnulib (often changing their name).
5973 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
5974 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
5975 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

5981 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
5982 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
5983 The manual mentions Gnulib more prominently.
5984 * doc/autoconf.texi (Gnulib): New node.
5985 (Pointers): Add Gnulib URL.
5986 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
5987 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
5988 Gnulib section.
5989 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
5990 suggest a #define rather than a typedef for _Bool, and mention
5991 Gnulib rather than trying to substitute stdbool code.
5992 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
5993 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
5994 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
5995 AC_STRUCT_DIRENT_D_TYPE.
5996 (Particular Types): Mention stdint.h and inttypes.h as standard
5997 headers too.
5998 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
5999 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
6000 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
6001 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
6002 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6003 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6004 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
6005 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
6006 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
6007 (Coding Style). Don't mention m4_expand_once.
6008 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
6009 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
6010 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
6011 (AC_CHECK_FUNCS): Use it.
6012 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
6013 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
6014 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
6015 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.

6046 Revert the patch from 2006-04-01 and only improve
6047 _AS_DETECT_BETTER_SHELL:
6049 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6050 skip nonexistent directories.
6051 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6052 only shell candidates which exist.
6053 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6054 * lib/autotest/general.m4 (AT_INIT): No need to give three
6055 parameters to _AS_PATH_WALK.
6057 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
6058 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6060 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6061 distinguish m4sugar macros.
6062 * tests/tools.at (autoupdating with aclocal and m4_include):
6063 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6064 test case by Noah Misch <noah@cs.caltech.edu>.
6066 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6068 Revert my change from 2006-03-17, in other words:
6069 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
6070 and DUALCASE=1.
6071 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
6072 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
6073 it is set.
6075 2006-04-07 Eric Blake <ebb9@byu.net>
6077 * doc/autoconf.texi (Programming in M4sh): Document that
6078 AS_MKDIR_P exits the script on failure.
6079 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6081 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6083 * config/elisp-comp, config/install-sh, config/mdate-sh,
6084 config/missing, config/mkinstalldirs: Sync from Automake.
6086 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
6087 from Automake.
6089 * doc/make-stds.texi: Sync from gnulib.
6091 2006-04-06 Eric Blake <ebb9@byu.net>
6093 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6094 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced

6098 Eric Blake <ebb9@byu.net>,
6099 Paul Eggert <eggert@cs.ucla.edu>,
6100 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6102 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6103 whether `set' quotes correctly: redirect stderr of the tested
6104 `set', and use a subshell, for Ultrix; use `sed' instead of
6105 `grep' for zsh `set' which may write binary output; match only
6106 at the beginning of a line, to avoid false positives.
6107 In order to avoid false positives by unrelated variables with
6108 multiline content, put the dump algorithm in a subshell and
6109 unset all variables containing newlines (except some which are
6110 special to the shell). Warn about cache variables that are
6111 unset.
6113 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6115 * config/config.guess, config/config.sub, config/texinfo.tex:

6118 * tests/mktests.sh: Reword comments.
6120 * tests/mktests.sh: Only skip internal macros starting with
6121 `_AC_' or `__AC_'. Noted by Stepan Kasal.

6123 (AC_ARG_VAR): Do test this now.
6124 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
6125 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
6126 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
6127 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
6129 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
6130 shell issue with double-quoted command substitutions of native
6131 commands.

6133 Marshall.
6135 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

6150 2006-04-06 Stepan Kasal <kasal@ucw.cz>
6152 * tests/Makefile.am (maintainer-check-posix):
6153 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
6155 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
6156 ac_config_<foo>s again, sometimes normalized, sometimes not.
6157 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6158 (AC_CONFIG_COMMANDS): Do not do so here.
6159 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6160 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6161 2005-07-25 rewrite. Noticed by Noah Misch.
6163 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6164 _AC_PRESERVE_HELP_ORDER, ...
6165 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
6167 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
6168 inside m4_expand_once; it is redundant.
6170 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
6171 for --help from Cygnus `configure.'
6173 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

6183 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
6184 Noah Misch <noah@cs.caltech.edu>
6186 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
6187 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
6188 * doc/autoconf.texi (Help Formatting): New node.
6189 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
6191 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6193 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
6194 lib/autoconf/specific.m4, lib/autoconf/status.m4,
6195 lib/autoconf/types.m4, lib/autotest/general.m4,
6196 tests/mktests.sh, tests/torture.at: White space cleanup:
6197 remove some SPACE before TAB, or add quoting ('' or @&t@).
6199 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
6201 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
6203 2006-04-05 Eric Blake <ebb9@byu.net>
6205 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
6206 empty test suite works.
6207 * tests/autotest.at (Empty test suite): Remove xfail.
6209 2006-04-05 Noah Misch <noah@cs.caltech.edu>
6211 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
6212 TAGS to ac_config_<foo>s.
6213 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
6214 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
6215 normalizing it, consistent it with previous releases.
6216 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
6218 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
6220 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
6221 Use simplified args that Eric Blake originally suggested.
6223 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
6225 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6226 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
6227 Use 'comm' rather than N instances of grep; this also fixes a bug
6228 whereby substrings were incorrectly matched, causing us to not
6229 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
6230 (exclude_list): Exclude empty macros.
6231 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
6233 Use awk rather than grep -E or egrep, to avoid
6234 portability problems with regular expressions containing newlines.

6236 Switch from grep to awk syntax.
6237 (ac_exclude_script): Renamed from ac_exclude_egrep.
6238 (au_exclude_script): Renamed from au_exclude_egrep.
6240 2006-04-04 Noah Misch <noah@cs.caltech.edu>
6242 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
6243 a subdirectory subject to Cygnus `configure'.
6244 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
6246 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
6247 report request when we have no AC_PACKAGE_BUGREPORT.
6249 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6251 * THANKS: Update.

6254 generated files.
6256 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
6257 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
6258 typedef'ed restricted pointer, to catch a compiler bug on
6259 HP-UX 11.x, and fix warnings so it passes with -Werror.
6260 (_AC_PROG_CC_C99): Likewise.
6261 Reported by Albert Chin <china@thewrittenword.com>.
6262 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.

6277 * THANKS: Add myself.
6279 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6281 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
6282 to log, point to testsuite output tree.
6284 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
6286 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.

6291 Remove; all uses removed.
6292 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

6312 Clean up _AC_COMPILER_EXEEXT* macros.
6314 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6315 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6316 ac_file to the name of the default output file and call
6317 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6318 initial `rm' of the candidate files...
6319 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6320 the same list in subsequent `rm' calls, and for the temporary
6321 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6322 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6323 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6324 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6325 no longer needed) by libtool. Make it a cache check.
6326 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6327 copied here by mistake.
6328 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6329 _AC_COMPILER_EXEEXT.
6330 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
6331 _AC_COMPILER_OBJEXT directly.

6362 * lib/autoconf/general.m4 (_AC_INIT_VERSION): Emit script name and
6363 Autoconf version number despite a zero- or one-argument AC_INIT.
6365 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
6366 subordinate tools.
6367 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
6368 * doc/autoconf.texi (autoreconf Invocation): Document it.
6370 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
6371 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.
6373 2006-04-01 Eric Blake <ebb9@byu.net>
6375 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Allow use in shell lists.

6377 rm failed to remove it.
6379 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6381 * bin/autoupdate.in: Redefine m4_location so that warnings print
6382 the correct lines of the input file by subtracting..
6383 (_au__first_line): ..this new definition.
6385 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
6386 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
6387 Remove stray newline in output.
6388 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
6389 AC_DEFUN this for autoconf, including the obsoletion diagnose.
6390 Fixes autoupdating of code where the replacement output contains
6391 m4sugar macros.
6392 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
6393 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

6395 * tests/tools.at: Several new tests for all of this.
6396 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
6397 hairy details.
6398 The AC_LANG_SAVE issue was reported against Libtool by
6399 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
6400 Kristian Kvilekval <kris@cs.ucsb.edu>.
6402 2006-04-01 Stepan Kasal <kasal@ucw.cz>
6404 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
6405 switch all of them on and of when necessary. Fixes the bug when
6406 m4sugar macros (e.g., m4_define) were expanded after the first
6407 automatic update (e.g., after AC_PREREQ or AC_INIT).
6409 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

6427 in texinfo files outside of verbatim environments.
6428 (syntax-check-rules): Update.
6429 * doc/autoconf.texi (Configuration Headers): Conform to it.
6431 2006-03-30 Chris Pickett <cpicke@cs.mcgill.ca> (tiny change)
6433 * doc/autoconf.texi (autoreconf Invocation): Mention that -I for
6434 aclocal cannot be given on the command line.
6436 2006-03-29 Paul Eggert <eggert@cs.ucla.edu>
6438 * doc/autoconf.texi (Programming in M4sh): Mention AS_BASENAME.
6439 Give an example for AS_DIRNAME instead of referring to Posix..
6440 (File System Conventions): Put discussion of // versus / here, and
6441 modernize it a bit.
6442 (Limitations of Usual Tools): Add basename. Remove verbiage
6443 after dirname, since it got moved to the above sections.
6444 All this was inspired by a patch proposed earlier by Eric Blake.
6446 2006-03-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6448 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Quote

6450 * lib/autotest/general.m4 (AT_INIT): Likewise.
6451 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Likewise, for
6452 `$0', $as_me.
6454 2006-03-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6456 * bin/autoscan.in: The value of find_configure_ac should be
6457 checked for existence, so we don't barf over a nonexisting
6458 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
6460 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7046 Factor functionality to..
7047 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
7048 `AC_SUBST($1)' in the public version.
7049 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
7050 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

7075 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
7076 conftest.o, to see whether the compiler really obeys; rm the object
7077 file before and after the test and register it with ac_clean_files.
7078 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
7080 2005-10-21 Stepan Kasal <kasal@ucw.cz>

7098 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
7100 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
7101 AC_LANG_PROGRAM, fixing a typo. Don't give details about
7102 the inner workings of AC_LANG_FUNC_LINK_TRY.
7103 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7104 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7105 by the function rather than ignoring it.
7106 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7107 comparing its address. Intel's interprocedural optimization was
7108 outsmarting the old heuristic. Problem reported by
7109 Mikulas Patocka.
7111 2005-10-19 Stepan Kasal <kasal@ucw.cz>
7113 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

7120 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7122 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7123 before removing it (chmod -R u+rwx); there are three instances of this.
7125 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7126 Stepan Kasal <kasal@ucw.cz>
7128 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7129 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7130 make its content writable before removing it. Remove an errorneous
7131 comment from the end, where the logs of the failed tests are copied
7132 to the main log file.
7134 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7136 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7137 in case the computer is too quick. Double quote the configure.ac
7138 snippets.
7140 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7141 problems if the testsuite were running too fast.
7143 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7145 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7146 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7147 (which belong to Xt, not X itself). See Debian bug 327655.
7148 * NEWS: Mention this.
7150 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7152 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7154 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7156 * config/move-if-change: Don't output "$2 is unchanged";
7157 suggested by Ben Elliston. Handle weird characters correctly.
7159 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7161 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7162 calls, so that the final expansion of this macro is shorter.
7163 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7164 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7165 the cleanup there. Use AS_VAR_* macros, to be more general.
7166 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7168 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7170 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7172 2005-09-01 Stepan Kasal <kasal@ucw.cz>
7174 * doc/autoconf.texi (Configuration Headers): Add an index entry
7175 for AH_HEADER.
7177 2005-08-26 Pavel Roskin <proski@gnu.org>
7179 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
7180 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
7181 running xmkmf.
7183 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7185 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7186 The previous patch didn't work, so try a better one.
7188 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7190 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7191 in the example. Reported by Bruno Haible.
7192 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7193 "if $undefined_var;" succeeds with my shell.
7195 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7196 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7197 but change the m4_divert_text to m4_divert_once.
7199 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7201 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7202 Work around bug in Solaris /usr/xpg4/bin/awk.
7203 The bug is present in at least Solaris 8 through 10.
7205 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7207 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7208 some evil values and relying on the fact that $* concatenates the
7209 parameters by the first character from IFS.
7211 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7212 Stepan Kasal <kasal@ucw.cz>
7214 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7215 first header appears, define AH_HEADER.
7216 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7217 Update limitations about when to call AC_CONFIG_HEADERS.
7218 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7219 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7220 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7221 ``Configuration Actions''; fix their index entries.
7223 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7224 options correctly. Process N-M as M-N if M is smaller than N.
7225 Process ranges correctly so that N-N will run only N.
7226 Sort and uniquify the tests that will be run. If there is more
7227 than one test, reinsert the banners for the tests.
7228 * tests/autotest.at (Keywords): Unmark XFAIL.
7230 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7232 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7233 before passing the macro name to AH_TEMPLATE.
7235 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7236 now opens log after option processing; in particular, --version
7237 and --help do not touch config.log.
7239 * Makefile.maint: Revert the change from 2005-08-12.
7241 2005-08-22 Stepan Kasal <kasal@ucw.cz>
7243 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
7244 common code to...
7245 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
7247 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7249 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7250 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7251 Language cleanup.
7253 * doc/autoconf.texi (Defining Symbols, Changed Results):
7254 Prepend to LIBS, not append, in examples.
7256 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7258 When building in place, set srcdir="."; suggested by Tim Van Holder.
7260 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7261 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7262 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7263 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7264 does not mean "no --srcdir option".
7266 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7268 * tests/autoscan.at (autoscan): New file.
7269 * tests/suite.at: Use it.
7270 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7271 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7273 * tests/autotest.at (Keywords): Test keywords combinations.
7275 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7277 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7278 add "2>&1"; gzip 1.2.4 prints help on stderr.
7280 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7282 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7283 was pushdef'ed twice while popped only once. Push it only once.
7284 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7286 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7288 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
7289 prefixed by mere "===", not "configure: === ".

7293 * Makefile.maint: Update from Bison.
7295 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7296 "<tab>" in comment, so that the point is understandable.
7298 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7300 Rewrite substantial part of lib/autoconf/status.m4.
7301 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7302 and CONFIG_COMMANDS are not processed in four separate loops.
7303 Instead, there is one main loop. This alows that the common code
7304 is expanded only once, thus config.status (and configure) is smaller.
7306 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7307 the AC_LIST_FILES and cousins macros are no longer used.
7309 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7310 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7311 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7312 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7313 contain the initialization, nor the for loop, nor the associated
7314 commands; all these go to ...
7315 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7316 _AC_OUTPUT_CONFIG_STATUS.
7317 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7318 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7319 (_AC_OUTPUT_FILE): The creation of the sed script ...
7320 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7321 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7322 _AC_OUTPUT_MAIN_LOOP.
7323 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7324 _AC_CONFIG_COMMANDS): Use ...
7325 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7326 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7327 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7328 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7329 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7330 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7331 ... new macros.
7332 (_AC_CONFIG_UNIQUE): Update.
7333 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7334 Replaced by this ...
7335 (_AC_LIST_TAGS): ... new common macro.
7336 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7337 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7338 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7339 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7340 this didn't belong to the `config commands' section.
7341 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7342 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7343 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7344 to the `config commands' section either.
7345 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7346 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7348 ... and many changes to the comments nearby.
7350 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7351 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7352 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7353 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7354 (#define header templates): The comment at the top of the generated
7355 header now includes the name(s) of the source file(s).
7357 Several unrelated small changes:
7359 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7360 parameter to AC_DIAGNOSE.
7361 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7362 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7363 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7364 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7365 with AU::AC_OUTPUT.
7366 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7367 in AC_OUTPUT doesn't double-quote it either.
7368 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7369 parameters.
7371 2005-07-10 Stepan Kasal <kasal@ucw.cz>
7373 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
7374 versions of Portland Group compiler produce single- and double-quoted
7375 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
7376 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
7378 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7380 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7381 This is a corrected version of yesterday's patch.

7390 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
7392 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7393 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7394 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7395 (AC_ARG_VAR): ... here.
7396 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
7397 target_alias.
7399 Keep a list of all precious variables and process them with one simple
7400 for loop, instead of expanding all commands, or, OTOH, complicated
7401 processing of output of "set".

7406 a loop to assign all ac_env_* and ac_cv_env_* variables.
7407 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
7408 to INIT_PREPARE.
7409 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
7410 its value to shell variable ac_precious_vars and call
7411 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.

7436 2005-07-05 Stepan Kasal <kasal@ucw.cz>
7438 Fix my changes from 2005-07-01; reported by Noah Misch.

7453 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

7458 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
7459 sed substitution command, so that we allow | in program prefixes

7463 configure_input, top_builddir, srcdir, etc.
7464 * lib/autotest/general.m4 (AT_INIT): Likewise, for
7465 PATH_SEPARATOR in AUTOTEST_PATH.
7467 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

7475 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

7501 for --help in that case.
7503 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
7504 matches the order of execution. No code changed.

7526 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
7527 (AC_SUBST): Call it.
7528 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7529 the directory specific variables; but don't call it for configure_input.
7531 2005-06-28 Derek Price <derek@ximbiot.com>
7533 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7534 addition.
7536 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

7539 directory have inherent problems with special characters like spaces,
7540 due to limitations in Make syntax. Problem reported by Alexandre
7541 Duret-Lutz.
7542 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

7555 from Justace Clutter.
7556 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
7557 variable into diagnostic. Make the diagnostic an error, not a warning,
7558 because we really don't support spaces and suchlike in dir names.
7559 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7560 Don't worry about backslashes in srcdir; it can't happen now.

7587 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
7588 b, t, r, w commands require single space, while : cannot have any.
7589 (Special Shell Variables): Fix sed code this in the example.
7590 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
7591 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
7593 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
7594 expand to the empty list. Don't use two pairs of m4_changequote,
7595 it's not necessary.

7603 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
7604 * doc/autoconf.texi:
7605 Don't mention Solaris versions so much, if a
7606 problem is common to all extant versions of Solaris. Say "SunOS
7607 4" instead of "SunOS" for SunOS 4.
7608 (awk): Mention more of the limitations of traditional Awk.
7609 (cat): Don't talk about cat -v.
7611 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

7616 to be compatible with glibc strverscmp.
7617 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
7619 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

7625 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
7627 * doc/autoconf.texi: "filesystem" -> "file system".
7628 "behaviour" -> "behavior".

7651 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7652 -u, since it outputs chatter if the input files are the same.
7653 Problem reported by Ralf Menzel.
7655 2005-06-08 Derek Price <derek@ximbiot.com>
7657 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7658 renaming them since they are about to be redefined anyhow.
7660 2005-06-08 Derek Price <derek@ximbiot.com>
7662 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7663 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7664 Move m4_undefine to alphabetical order.
7666 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
7668 * README: Recommend GNU M4 1.4.3 or later.
7669 * doc/autoconf.texi (Introduction): Likewise.
7670 Reword to avoid some formatting glitches.
7671 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.

7673 Redo example output tp match current CVS snapshot.
7674 Use @example.org in email addresses when the examples
7675 might get inadvertently cut-and-pasted into user code.
7676 Remove example of autom4te usage that doesn't seem to work now.
7677 Use modern AC_INIT (except when the example is meant to be
7678 shown with Autoconf 2.13).
7679 Update ksh info for Solaris 9 and later.
7680 KB -> kB.
7681 Modernize description of Automake versions a bit.

7689 Reword to avoid some formatting glitches.
7690 * doc/installt.exi: Reword to avoid some formatting glitches.
7692 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7693 Tru64 ksh pattern matching bug. Reported against Libtool by
7694 Albert Chin <libtool@mlists.thewrittenword.com> and
7695 Nicolas Joly <njoly@pasteur.fr>.
7697 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7699 m4_cdr of one-member list was [[]] (one-member list containing an
7700 empty string) instead of [] (an empty list. Callers were skewed to
7701 match this misbehaviour. As a consequence of this:
7702 - m4_foreach([x], [], [foo]) expanded to `foo', while
7703 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7704 This bug has been fixed:
7706 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7707 expand to an empty string; print error msg if called without
7708 an argument list.
7709 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7710 misbehaviour; handle [] and [[]] correctly.

7718 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
7720 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7721 swallow records with more than 99 fields.
7722 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7723 parse the long line.
7725 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7727 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7728 swallow literals longer than 399. Reported by Ralf Wildenhues.

7734 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
7735 to gfortran, and make these the first two compiler names
7736 checked (following the general autoconf preference for gcc).
7738 2005-06-03 Stepan Kasal <kasal@ucw.cz>
7740 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
7741 (DISTCLEANFILES): Remove $(check_SCRIPTS).

7746 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
7747 expression of unbounded size when processing the --list
7748 option. This runs afoul of a limit of 399 bytes per regular
7749 expression on AIX. Problem reported by Ralf Wildenhues.

7760 2005-05-31 Dan Manthey <dan_manthey@partech.com>
7762 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7763 now contain newlines, and substituted files must be referenced on
7764 a line alone; the sed scripts to substitute them are now very
7765 different.
7766 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
7767 commands can be put in a sed script portably.
7768 * doc/autoconf.texi (Setting Output Variables): Document above

7780 * tests/local.at: Don't attempt to check for negated character
7781 classes in shell scripts. The test was too brittle.
7783 2005-05-25 Stepan Kasal <kasal@ucw.cz>
7785 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
7786 * doc/autoconf.texi (Limitations of Builtins): Document this
7787 limitation.
7789 2005-05-24 Stepan Kasal <kasal@ucw.cz>

7799 messages when ac_unique_file is not found.
7800 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
7801 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo

7817 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
7818 (ac_top_builddir): ... this ...
7819 (ac_top_build_prefix): ... to this; the old name is also kept, for
7820 backward compatibility.
7821 (ac_top_builddir_sub): New variable, without the trailing slash,
7822 always nonempty.
7823 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

7837 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7838 argument to m4_foreach. I guess it was necessary in the past,
7839 but I think it's a no-op now.
7841 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7843 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7844 ``cat <<_ACEOF'' commands to one.
7845 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
7846 * lib/autoconf/status.m4: On various places, use expr instead of
7847 ``echo|sed.''
7848 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
7849 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
7850 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
7851 a range.
7852 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
7853 the wrong patterns between ``case'' and ``esac.'' The previous
7854 code had false positives.
7856 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
7858 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
7859 as on 2005-05-02.
7860 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
7861 Mention LIBOBJDIR.

7904 check.
7905 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
7906 enough arguments, similarly as in m4_bpatsubsts.
7908 2005-05-12 Stepan Kasal <kasal@ucw.cz>
7910 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
7911 of absolute paths.
7913 2005-05-11 Stepan Kasal <kasal@ucw.cz>
7915 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
7916 for absolute directory names in one loop.
7917 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
7918 abbreviations of --version and --debug.
7920 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
7922 * doc/autoconf.texi (Autoconf Language): Be more precise about
7923 quoting rules. Problems noted by Stepan Kasal.
7924 Also, throughout this document, be more careful about white space.
7925 "blank", "white space", and "space" all have different meanings
7926 and we should be careful to say what we mean.
7928 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
7930 Fix C++ related problems reported by Werner Lemberg.
7931 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
7932 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
7933 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
7934 avoid problems with C++ and throw.
7935 * tests/compile.at: .cpp, not .cc.
7937 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
7939 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7941 * doc/autoconf.texi (Generic Functions): Typos.
7943 2005-05-02 Gary V. Vaughan <gary@gnu.org>
7945 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
7946 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
7947 set by latest automake.
7949 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7951 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
7952 outputs 0 on GNU/Linux these days.
7954 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
7956 * doc/autoconf.texi (Autoconf Language): Add more description
7957 about quoting heuristics.
7958 (Limitations of Builtins): Describe "set -" problems.
7960 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7962 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
7963 not newline.
7965 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
7966 by AC_DEFINE; it was a mistake.
7967 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
7969 2005-04-25 Stepan Kasal <kasal@ucw.cz>
7971 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
7973 2005-04-22 Stepan Kasal <kasal@ucw.cz>
7975 * doc/autoconf.texi (External Software): Quadrigraphs are not
7976 processed correctly in AS_HELP_STRING; avoid this in the examples.
7977 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7978 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7979 comment and reduce m4_default([foo], []) to [foo].
7980 (m4_strip): Update the explanation.
7982 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
7984 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
7985 Remove core.conftest.* too; it's generated by Tru64 5.1.
7986 Problem reported by Jennis Pruett.
7987 * lib/autoconf/functions.m4
7988 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
7989 Don't bother to remove core files; AC_RUN_IFELSE should do that
7990 for you.
7992 2005-04-19 Stepan Kasal <kasal@ucw.cz>
7994 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
7996 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>

8001 2005-04-15 Stepan Kasal <kasal@ucw.cz>
8003 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
8004 the comment.
8006 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
8008 * doc/autoconf.texi (External Software, Package Options): Add
8009 examples showing how to implement --with-* and --enable-* options.
8011 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8013 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
8014 as well as configure.in. Problem reported by Gregorio Guidi.
8016 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
8018 * doc/autoconf.texi (Particular Functions): Use gnulib's current
8019 pattern for alloca snippet.
8021 2005-04-04 Stepan Kasal <kasal@ucw.cz>
8023 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
8025 2005-04-01 Stepan Kasal <kasal@ucw.cz>
8027 * doc/autoconf.texi (Generic Programs): Fix a typo.
8029 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
8031 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
8032 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
8034 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8036 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8037 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8038 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8039 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8040 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8042 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8044 * NEWS: The configure command now warns you if you attempt to use
8045 a directory whose name contains a special character like space,
8046 newline, or "\".
8047 * doc/autoconf.texi (Installation Directory Variables): Allow
8048 "," in file names. Do not use \@; it's not a portable regexp.
8049 * bin/Makefile.am (edit): Likewise.
8050 * lib/Makefile.am (edit): Likewise.
8051 * tests/Makefile.am (edit): Likewise.
8052 * tests/semantics.at: Likewise.
8053 * tests/torture.at: Likewise.
8054 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
8055 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
8056 * doc/autoconf.texi (File System Conventions): Warn about
8057 unportable file names.
8058 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8059 (AC_INIT): Use it.
8060 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8061 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8062 ac_pwd, and quote srcdir.
8063 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8065 * doc/autoconf.texi: Fix some systematic formatting problems.
8066 ".)" needs a following @: if not at the end of a sentence, and
8067 similarly for "!)". "etc." should be preceded by a comma.
8068 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8070 2005-03-22 Bruno Haible <bruno@clisp.org>
8072 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8073 argument is often called 'build-aux'.
8075 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8077 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8078 macro AC_TRY_LINK is obsolete.
8079 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8080 `AC_CONFIG_FILES'.
8082 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8084 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8085 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8086 from a Common Lisp's `cl'.
8087 (AC_PROG_CXX): Behave according to the documentation: don't
8088 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8089 make the variable CCC precious; use `cl.exe', not `cl'.
8091 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8092 Alexandre Duret-Lutz <adl@gnu.org>
8094 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8095 /dev/null, as "configure" shouldn't read stdin, and this insulates
8096 us from problems (e.g., when testing for "cl"). Also, do this
8097 redirection before invoking "hostname" or "uname", and keep the
8098 original input stream available via...
8099 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8100 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8101 bother with "</dev/null" since it's now done at the top of
8102 'configure'.
8103 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8104 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8105 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8106 * doc/autoconf.texi (File Descriptor Macros): New section.
8107 (Printing Messages): Mention it.
8108 * tests/base.at (Input/Output): New test.
8110 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8112 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8113 newline if neither \c nor -n work, as that would output two
8114 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8116 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8118 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8119 This causes that any required macros inside will get before the if.
8120 * doc/autoconf.texi (autom4te.cache): A typo.
8122 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8124 Undo previous change, except keep the change to
8125 lib/autoconf/programs.m4 that replaced grep with shell
8126 pattern-matching. This is because net-snmp configure reads stdin.
8127 Reported by Noah Misch.
8129 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8131 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8132 from /dev/null, as "configure" shouldn't read stdin, and this
8133 insulates us from problems (e.g., when testing for "cl").
8134 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8135 before invoking "hostname" or "uname".
8136 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8137 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8138 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8139 "</dev/null" since it's now done at the top of 'configure'.
8140 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8141 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8142 Also, replace grep with shell pattern-matching, to save a process.
8144 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8146 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8147 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8148 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8149 compiler.
8151 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8153 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8154 grep -q isn't portable. Improve grep -s explanation.
8155 Problem reported by Dan Manthey.
8157 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8159 * doc/autoconf.texi (Special Shell Variables): Clarify
8160 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8162 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8164 * doc/autoconf.texi: Use @acronym for DJGPP.
8165 Fix some @code's that should have been @env's, and vice versa.
8166 Sort environment variable names.
8167 Mention that shells no longer inherit IFS.
8168 Don't recommend PATH_SEPARATOR=';' so strongly.
8169 Mention that $RANDOM might expand to the empty string.
8170 "symlink" and "soft link" -> "symbolic link".
8171 Improve mktemp description (reported by Bruno Haible).
8173 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8175 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8176 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8177 Likewise.
8178 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
8179 Likewise.
8181 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8183 * NEWS: Mention AT_COPYRIGHT.
8185 * tests/local.at (AT_CMP): Use diff directly on input files rather
8186 than copying them.
8188 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8189 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8191 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8192 and Paul Eggert <eggert@cs.ucla.edu>
8194 * tests/autotest.at (Empty test suite): New test.
8195 * tests/torture.at (Substitute and define special characters)
8196 (Substitute a 2000-byte string, Define to a 2000-byte string)
8197 (Substitute a newline, Define a newline): New tests.
8199 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8201 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
8202 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8203 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8204 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8205 (Standard regular expressions): New test.
8206 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8207 excess test name quoting.
8208 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8209 CPPFLAGS to `configure' instead of setting it in `configure'.
8211 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8212 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8213 on some platforms.
8215 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
8216 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
8218 * tests/local.at (AT_CMP): New macro.
8219 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
8220 (AC_SAVE_STATE): Move environment grep...
8221 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
8222 (AT_CONFIG_CMP): New macro.
8223 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
8224 * tests/c.at (Extensions): Do not exit early.
8225 * tests/atlocal.in: Inherit $GREP.
8227 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
8228 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
8230 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
8231 (AC_COPYRIGHT): Factor header comment portion out and move into...
8232 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
8233 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
8234 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
8235 --version output.
8236 * tests/local.at: Add Autoconf test suite copyright notice.
8237 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
8239 2005-02-04 Bruno Haible <bruno@clisp.org>
8240 and Paul Eggert <eggert@cs.ucla.edu>
8242 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
8244 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
8246 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
8247 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
8249 Try not to generated lines of unlimited length, as POSIX places a
8250 2047-byte limit on line length of portable text files.
8251 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
8252 Use newline as a separator, not space.
8253 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
8254 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
8255 space.
8257 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8259 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
8260 as_func_*. Add test to check whether positional parameters
8261 are restored after function return.
8263 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
8265 * doc/autoconf.texi (Special Shell Variables): Mention _,
8266 BIN_SH, DUALCASE. Say that variables other than "status" are safe
8267 if they contain a lower-case letter. The DUALCASE problem was
8268 reported by Ralf Wildenhues.
8270 * bin/autoconf.as: Don't exit with status 0 after write failure
8271 with --help or --version.
8272 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

8310 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8311 Update the long comment explaining it.
8313 m4_require no longer writes an ``is required by'' line to the
8314 execution stack. It contains only one bit of non-redundant
8315 information: that the macro was required, not called. And even
8316 this bit is useless in most situations: have you ever met a macro
8317 which both calls and requires the same macro?
8319 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8320 (_m4_defun_pro_outer): ... only via this macro, for the outermost

8323 (m4_expansion_stack_pop): Remove the misplaced comment.

8327 (_m4_require_call): Use it.
8328 * tests/m4sugar.at (m4_require): Expect output without the
8329 ``is required by'' messages.
8331 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8333 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
8334 rather than x for expr.
8336 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
8337 this is safe.
8338 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
8339 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

8352 support.
8353 * bin/autoheader.in: Pass $force to update_file so that
8354 config.h.in is always recreated when --force.

8358 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
8360 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
8362 * doc/autoconf.texi (Limitations of Builtins): Clarify that

8365 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
8367 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
8368 Warn about newline stripping in `` and $(). Update Solaris
8369 version to 9.

8371 X insulates us from future changes to Posix.
8372 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
8373 stripping.
8375 2005-01-19 Stepan Kasal <kasal@ucw.cz>
8377 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

8395 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
8397 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
8399 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

8421 (_m4_divert_n_stack): New macro; the expansion is
8422 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
8423 otherwise.
8424 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
8425 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8426 stored in _m4_divert_diversion or _m4_divert_dump.
8427 (m4_divert_pop): When the parameter is given, compare the symbolic
8428 name with the last diversion pushed on the stack. Previously, the
8429 current diversion was compared with the numeric value of the
8430 diversion given as the parameter.
8431 (m4_require): If the macro hasn't been expanded yet, call ...
8432 (_m4_require_call): this new macro.

8465 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

8467 not essential. Reported by Magnus Therning.
8468 * tests/torture.at (autoreconf.): New banner.
8469 (autoreconf and non-AC configure): Rename to `Non-Autoconf
8470 AC_CONFIG_SUBDIRS'.

8518 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
8519 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

8646 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

8733 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
8734 value of the #define--default to 1, iff the macro was called
8735 with exactly one parameter.
8737 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
8739 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
8740 "char c = '\200';" rather than "char c = 0x80;" as the
8741 latter doesn't conform to the strict C standard due to
8742 overflow on signed char hosts.
8744 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
8745 to -qlanglvl=ansi. We don't want to disable extensions.
8747 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
8749 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
8750 (Using Autotest, testsuite Scripts, Writing testsuite.at):

8801 simplify the examples and improve their quoting.
8803 2004-11-13 Stepan Kasal <kasal@ucw.cz>
8805 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
8806 the $1_found variable, don't test whether the file is executable;
8807 Both things are checked ...
8808 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
8809 the former ``test -f''.
8810 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
8812 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

8817 2004-11-10 Derek R. Price <derek@ximbiot.com>
8819 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
8820 limitations. Reorder paragraphs for clarity.
8822 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
8824 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
8825 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
8826 variants", "Unix", and some related minor wording fixups.
8828 (Shellology, Special Shell Variables): Document that the Zsh
8829 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks

8843 * doc/autoconf.texi (auindex): New macro.
8844 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
8845 Problem reported by Stepan Kasal.
8847 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
8849 Fix problems reported by Andreas Buening in:
8850 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
8851 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
8852 in test makefile.
8853 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
8854 readable; it's not true in OS/2-emx.
8856 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
8858 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
8859 "/usr/include", clear ac_x_includes instead of leaving it as "no"
8860 (trivial change). Problem and patch reported by Andrew Church in:
8861 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
8863 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

8868 Also, fix some minor spacing and punctuation bugs.
8870 2004-09-02 Akim Demaille <akim@epita.fr>
8872 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and

8888 * README: Add advice about m4 1.4.2.
8890 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
8891 texinfo.tex for now (done by hand now).
8892 * Makefile.maint (wget_files, cvs_files):
8893 Remove ansi2knr.c; nobody uses it.
8894 (ansi2knr.c-url_prefix): Remove.
8895 (cvs-update): Fix test for failure. I don't know why it ever
8896 worked...
8898 * doc/autoconf.texi: Update URLs, some of which went stale.
8899 Use @uref rather than @href.
8901 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
8902 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
8904 * config/config.guess, config/config.sub, config/elisp-comp,
8905 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
8906 doc/fdl.texi, doc/standards.texi: Sync with master copy.
8908 * NEWS, TODO, configure.ac, bin/autoscan.in,
8909 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
8910 doc/install.texi, lib/Autom4te/Configure_ac.pm,

8914 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
8915 tests/tools.at, tests/torture.at:
8916 Use "file name" rather than "filename" or "path",
8917 to be consistent with the terminology of the GNU coding standards.
8919 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
8921 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
8922 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
8923 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
8924 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
8926 More fixes to support spaces in the name of the build directory.
8927 This isn't a complete fix but it's an improvement.
8929 * bin/autoconf.as (autom4te_options): New var.
8930 Use it instead of appending to AUTOM4TE, so that we can allow
8931 spaces in the build directory's absolute name.
8932 * bin/autoheader.in ($autoconf): Allow spaces in file names.
8933 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
8934 AT_CHECK_NOESCAPE): Likewise.
8935 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
8936 main program): Likewise.
8938 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
8940 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
8941 From Ralf Corsepius in:
8942 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
8944 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
8946 * doc/autoconf.texi (Function Portability): Document isinf and
8947 and isnan. From a suggestion by Kevin Ryde.
8949 * lib/Autom4te/General.pm (END): Return correct exit status even
8950 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
8952 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
8954 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
8955 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
8956 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
8958 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
8960 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
8961 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
8962 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
8963 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
8964 * lib/autom4te.in (Automake-preselections): Preselect
8965 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
8967 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
8969 * lib/autom4te.in (Automake-preselections): Preselect
8970 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
8971 trace them.
8973 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
8975 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
8976 Tru64.
8977 * doc/autoconf.texi (Shellology): Mention BIN_SH.
8978 Document problem with "`""`" in pdksh POSIX mode.
8980 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
8982 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
8983 with pdksh, too. Problem reported by Patrick Welche via
8984 Gary V. Vaughan.
8985 * doc/autoconf.texi (Shellology): Note that set -o posix is
8986 useful for pkdsh, too.
8988 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
8990 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
8991 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
8992 Don't fail if ENV or BASH_ENV is readonly.
8993 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
8994 etc. are read only. Problem reported by Ludovic Courtes.
8996 2004-06-23 Noah Misch <noah@cs.caltech.edu>
8998 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
8999 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9000 (trivial change)
9002 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9004 * doc/autoconf.texi (File System Conventions): Warn about
9005 names like "aux". Problem reported by Eric Blake.
9007 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9008 by zero instead of array size, so that we can use any arithmetic
9009 constant expression (instead of requiring an integer constant
9010 expression). This allows us to test expressions like DBL_MAX <
9011 LDBL_MAX, which didn't conform to the C standard using the old
9012 method.
9013 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9014 now that we can do floating-point tests at compile time.
9016 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9018 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9019 and LDBL_EPSILON, as the resulting expression isn't an
9020 integer constant expression and violates the C standard.
9021 Problem reported by Nelson H. F. Beebe. Also, check
9022 for "L" suffix, and check that long double doesn't have
9023 worse range or precision than double, that mixed-mode
9024 arithmetic doesn't generate a diagnostic, that double
9025 constants fit in long double.
9027 2004-06-03 Kevin Ryde <user42@zip.com.au>
9029 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9030 malloc(0) and realloc(NULL,size).
9032 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9033 Bob Proulx.
9035 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9037 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9038 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9039 by Jim Meyering.
9041 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9043 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9044 can be rewritten using if-then-else. Suggested by Bruno Haible.
9046 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9048 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9049 Problem reported by Stepan Kasal.
9051 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9053 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9054 change). Patch reported by Ralf Wildenhues in
9055 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9057 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9058 function F exists if the compiler and linker let you compile an
9059 expression like (F != 0). Recent versions of GCC optimize away
9060 the reference to F in that case, since every function address must
9061 be nonzero, so the link succeeds even if F does not exist.
9062 Problem reported by Manu in
9063 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9065 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9066 "Unix". Many uses changed.
9067 (Limitations of Builtins): Explain better why the ! command isn't
9068 portable.
9070 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9072 * lib/autom4te.in (Automake-preselections): Preselect
9073 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9075 2004-05-19 Kevin Ryde <user42@zip.com.au>
9077 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9078 referencing AC_FUNC_STRERROR_R.
9080 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9081 note pessimistic assumption when cross compiling.
9083 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9085 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9086 (until 2004) invoked subcommands with sh -e, contra POSIX.
9087 Reported by Kevin Ryde.
9089 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9091 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9092 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9093 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9094 `test -f " /usr/bin/grep"', which _always_ failed.
9095 (AC_PROG_SED): Ditto bogus PATH fix.
9096 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9097 requires that grep correctly supports _multiple_ `-e' options, rather
9098 than stating only that grep should accept `-e'.
9100 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9102 Port to C99, which requires that 'exit' be declared.
9104 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9105 to ensure that stdlib.h is included.
9106 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9107 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9108 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9109 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9110 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9111 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9112 when using 'exit' in a test; C99 requires that 'exit' be declared.
9114 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9116 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9117 now prefers 'grep' implementations that accept -e.
9118 (Limitations of Usual Tools): Describe problems of traditional
9119 egrep and fgrep with long input lines, and of traditional grep
9120 with -e.
9121 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9122 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9123 All callers changed. Append /usr/xpg4/bin to the PATH, for
9124 Solaris.
9125 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9126 the user with complaints about multiple -e options.
9127 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9128 Define it with AC_PROG_GREP.
9129 * configure.ac (AC_PROG_GREP): Add.
9130 * lib/freeze.mk (GREP): New macro.
9132 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9134 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9135 a possible candidate only after all others fail, rather than
9136 consulting it first. This improves backward compatibility by
9137 better reflecting the way shell selection occurred in previous
9138 versions of Autoconf, and should help to avoid triggering latent
9139 problems in other packages, such as the one in Automake where zsh
9140 is not handled robustly:
9141 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9142 Although it is not Autoconf's responsibility to work around
9143 problems in Automake, it nevertheless makes sense to avoid
9144 introducing unnecessary incompatibilites.
9146 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9147 Gary V. Vaughan <gary@gnu.org>
9149 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9150 how deeply nested we are when a suitable tool is found, set the
9151 ac_path_TOOL_found flag.
9152 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9153 nested we are in this macro. Break out of all 3 nested loops if
9154 ac_path_TOOL_found is set.
9156 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9158 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9159 of the _AS_PATH_WALK loop too if GNU flavor is found.
9161 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9163 * doc/autoconf.texi (Limitations of Make): Update documentation
9164 for `$<'. New entry `Long lines', based on a report from Simon
9165 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9166 paragraph about DJGPP, based on a mail from Richard Dawe.
9168 2004-04-20 Paul Eggert <eggert@twinsun.com>
9170 * tests/c.at (C keywords): Don't assume that GCC supports
9171 "restrict" and "inline", as sufficiently-old GCC versions do not
9172 (also, GCC configured to be in pedantic C89 mode does not).
9173 Problem reported by Sumit Pandya in:
9174 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9176 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9177 consider -g to work if it generates warnings when plain compiles
9178 don't. Problem reported by Braden McDaniel in:
9179 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9181 * doc/autoconf.texi (Slashes): New section, to document a problem

9192 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9193 best tool so far counter rely on the tool path variable name to
9194 avoid checks for one tool being affected by the results of running
9195 the length check on a previous tool.
9197 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9198 match expression argument, as different greps have different
9199 regular expression flavours.
9200 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9201 literals.
9202 (AC_PROG_EGREP): Pass 'EGREP$'.
9203 (AC_PROG_GREP): Pass 'GREP$'.
9205 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>

9212 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9213 Types, Specific Compiler Characteristics, System Services,
9214 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9215 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9216 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9217 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

9230 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9231 now defines HAVE_DECL_TZNAME if it is declared, when
9232 HAVE_STRUCT_TM_TM_ZONE is not defined.
9233 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9234 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
9235 for HAVE_TZNAME.
9237 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
9239 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected

9251 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
9252 quoted -cmdline argument in Portland Group compiler (bug
9253 reported by Jeffrey J. Barteet).

9281 behavioral changes.
9282 * tests/mktests.sh: Do not generate tests for the
9283 new macros.
9284 * NEWS: Document these changes.
9286 * doc/autoconf.texi: Avoid macros with unbraced arguments,
9287 they make TeX hang up.

9292 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
9293 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
9294 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
9295 vowel.

9312 from the next generation of Libtool.
9313 * lib/autom4te.in (Autoreconf-preselections): Ditto.
9315 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9317 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
9318 is not always thread-safe. Report from Nathanael Nerode.
9320 2004-02-18 Paul Eggert <eggert@twinsun.com>
9322 Fix a dependencies problem, stemming from a Autoconf 2.59 build
9323 problem on QNX reported by Stephen Rasku in
9324 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
9326 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
9327 $(m4sh_m4f_dependencies); this removes a FIXME.
9328 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
9329 (MAINTAINERCLEANFILES): Split into pieces,
9330 one per related section. Add $(srcdir)/wrapper.in.
9332 2004-02-09 Paul Eggert <eggert@twinsun.com>
9334 * doc/autoconf.texi (Setting Output Variables): Emphasize that
9335 AC_SUBST provides no portable way to escape literal newlines.
9337 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9338 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9339 Darwin uses -lcrt2.o and there's little point to cataloging all
9340 the system variants. Partial fix reported by Andreas Waechter in:
9341 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

9357 the behavior of the third argument.
9358 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
9359 correctly the behavior of the third argument. Document
9360 what the three macros that AU_DEFUN defines do. Fix
9361 warning message when the third argument includes $0

9364 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
9365 Eric Sunshine <sunshine@sunshineco.com>
9366 Paul Eggert <eggert@twinsun.com>
9368 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

9370 parameter. Expand _AS_SHELL_FN_SPY.
9371 (AS_INIT_WITH_SHELL_FN): Removed.
9372 (_AS_SHELL_FN_SPY): New macro.
9373 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
9374 macros.
9375 (AS_SHELL_SANITIZE): Remove loop to find better shell
9376 and documentation for the parameter.

9380 (AS_REQUIRE_SHELL_FN): Require shell functions when
9381 it is used.
9382 (_AS_LINENO_WORKS): Put around braces, we do not
9383 trigger the bash bug anymore.
9384 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
9385 use AS_INIT_WITH_SHELL_FN.
9386 * bin/autoconf.in, tests/wrapper.in: Regenerated.
9388 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
9390 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

9394 (AU_DEFUN): Honor the third parameter, create autoupdate
9395 macros with AU_DEFINE.
9396 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
9397 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

9416 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
9417 2003 (except 1997) to the list of copyright years. This undoes
9418 the 2003-05-22 change, which removed the older years from the list.
9419 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
9421 2004-01-27 Gary V. Vaughan <gary@gnu.org>
9422 Albert Chin-A-Young <china@thewrittenword.com>

9432 _AC_PROG_GREP, and AC_PROG_SED.
9433 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
9434 longest input length accepted by a command.
9435 (AC_PROG_SED): Use it.
9436 * doc/autoconf.texi (Particular Programs): Document the changes.
9437 * NEWS: Updated.
9439 2004-01-27 Paul Eggert <eggert@twinsun.com>

9461 sources.
9463 2004-01-26 Paul Eggert <eggert@twinsun.com>
9465 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9466 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9467 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9468 not <inttypes.h>. Problem reported by Tim Mooney in
9469 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9470 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9471 Likewise.
9473 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9474 otherwise "make check" fails because it forbids cmp (I guess
9475 because cmp treats files as binary on DOS-like systems).
9477 * tests/mktests.sh: Update copyright date to 2004, since some tests
9478 have changed in 2004.
9480 2004-01-23 Gary V. Vaughan <gary@gnu.org>
9482 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
9483 non-truncating sed or gsed program in PATH.
9484 * tests/acprograms.at: Add it.

9486 * NEWS: Updated.
9488 2004-01-15 Paul Eggert <eggert@twinsun.com>
9490 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9491 -std1 disables some useful extensions on Tru64. Problem reported
9492 by N. Lichtmaier in
9493 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
9495 2004-01-14 Paul Eggert <eggert@twinsun.com>
9497 * doc/autoconf.texi (Programming in M4sh): Document that
9498 AS_MKDIR_P succeeds if the destination is a symbolic link
9499 to an existing directory.
9500 (Limitations of Usual Tools): Note that mkdir -p might not
9501 succeed on symlinks to directories.
9503 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9505 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
9506 * bin/autoheader.in: Grammar fix in message.
9507 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
9508 Test for dir before calling mkdir -p. (trivial changes)
9510 2004-01-13 Eric Blake <ebb9@byu.net>
9512 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
9513 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
9515 2004-01-10 Jim Meyering <jim@meyering.net>
9517 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
9519 2004-01-09 Paul Eggert <eggert@twinsun.com>
9521 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9522 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9523 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9524 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9525 AC_COMPILE_IFELSE, since we now assume our caller invokes
9526 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9527 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9528 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9529 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9531 2004-01-07 Paul Eggert <eggert@twinsun.com>
9533 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9534 `"'...'"`, as it's confusing (and I suspect it may not work on
9535 some platforms). The code was incorrect anyway, as it assumed
9536 that \$ evaluated to itself in that context. Reported by
9537 Alexandre Duret-Lutz.
9539 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9541 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
9542 and _LT_AC_TAGCONFIG.
9544 2004-01-06 Paul Eggert <eggert@twinsun.com>
9546 * doc/autoconf.texi (One Macro Call): Fix an incorrect
9547 example, and add more examples. Reported by Eric Sunshine.
9549 2004-01-05 Paul Eggert <eggert@twinsun.com>
9551 * doc/autoconf.texi (Limitations of Usual Tools):
9552 Remove warning against "rm -fr" introduced yesterday; it
9553 was a false alarm.
9555 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
9556 autoscan, autoupdate, ifnames): Don't use chmod -w.
9557 * lib/Makefile.am (autom4te.cfg): Likewise.
9558 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
9559 "chmod -w".

9562 Paolo Bonzini <bonzini@gnu.org>
9564 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
9565 by doing lineno substitution only on lines containing "$LINENO".
9567 2004-01-04 Paul Eggert <eggert@twinsun.com>
9569 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
9570 Use "rm -f" to remove conftest.sed, not plain "rm".
9571 Bug reported by David Relson in
9572 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
9574 * Makefile.am (autom4te-update):
9575 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
9576 * Makefile.maint (my-distcheck, do-po-update): Likewise.
9577 * doc/autoconf.texi (Guidelines): Likewise.

9587 Warn against "rm -fr".
9589 2004-01-03 Paul Eggert <eggert@twinsun.com>
9591 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9592 -c -o might not work. From a suggestion by Kevin Ryde.
9593 (C Compiler, Generating Sources, Limitations
9594 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9595 Don't put '-o' after non-options, as POSIX doesn't allow this.
9596 Mention that cc's name might be gcc or c89 or whatever.
9598 2004-01-04 Kevin Ryde <user42@zip.com.au>
9600 * doc/autoconf.texi: Add various further index entries.
9602 2003-12-29 Paul Eggert <eggert@twinsun.com>
9604 * bin/autoreconf.in (autoreconf_current_directory):
9605 Fix typo: mkdir without umask arg.
9607 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
9609 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9610 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
9611 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
9612 explanation clearer.
9614 2003-12-24 Andreas Schwab <schwab@suse.de>
9616 * doc/autoconf.texi (Default Includes): Fix misspelling of
9617 AC_INCLUDES_DEFAULT.
9619 2003-12-03 Paolo Bonzini <bonzini@gnu.org>

9664 (&sizes): New.
9665 Use them.
9666 No longer rely on Gnus to inline the list of signatures: compute
9667 them on the fly.
9669 2003-11-24 Akim Demaille <akim@epita.fr>
9671 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

9740 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

9876 cross test.
9878 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
9880 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
9881 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

9895 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
9897 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
9898 -mGLOB_options_string stuff for Intel ifc, which can cause
9899 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
9900 pattern-matching instead of grep.

9922 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
9923 cache variable instead of $G77 to decide whether to include -O2,
9924 since $G77 is specific to Fortran 77.

9928 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

9933 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
9934 arguments so that it can be used with syntax identical to
9935 AC_PROG_F77, and so that we can more easily decide to
9936 remove/deprecate the DIALECT optional argument in the future if it
9937 proves troublesome.
9938 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
9939 non-freeform-supporting compilers. Document freeform flags.

9943 * configure.ac: Look for emacs, not macs.

9946 2003-10-03 Akim Demaille <akim@epita.fr>
9948 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
9949 * bin/autoreconf.in (autoreconf_current_directory): Create the

9953 2003-10-03 Akim Demaille <akim@epita.fr>
9955 * configure.ac: Quotation and formatting changes.

9978 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.

10004 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10005 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
10006 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
10008 2003-09-26 Akim Demaille <akim@epita.fr>
10010 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10011 directory for AC_CONFIG_COMMANDS' first argument exists.
10012 This makes valid the invocation of _AC_SRCPATH that follows.
10013 Reported by Eric Sunshine.
10014 * doc/autoconf.texi (Configuration Commands): Adjust.
10016 2003-09-26 Akim Demaille <akim@epita.fr>

10019 Reported by Ralf Corsepius.
10021 2003-09-26 Akim Demaille <akim@epita.fr>
10023 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
10024 arguments.

10037 The test suite are sometimes assigning timings incorrectly.
10038 Reported by Henk Krus.
10039 Diagnosed by Nicolas Joly.
10041 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10042 AT_help_all.
10043 Instead of making AT_help a sequence of assignments to grow
10044 $at_help_all, just make AT_help_all be the growing contents of
10045 $at_help_all, and make a single assignment in...
10046 (AT_INIT): here.
10047 (at_times_skip): Flip the meaning and rename as...
10048 (at_times_p): this.
10049 (AT_INIT): When summarizing the test that ran, remove
10050 $at_times_file after use, and check it is present before trying to
10051 use it.

10059 (ifnames): chmod -w.
10060 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10061 executables, not bin/ executables! Otherwise all the magic needed
10062 to find non installed files is turned off. This caused a failure
10063 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10064 as found in its environment (sent by tests/autoreconf): pointing
10065 to bin/autom4te that could not find its files.
10066 * tests/mktests.sh: Force the replacement of generated files, for
10067 the sake of "mv" program that are interactive when overwriting a
10068 -w file.

10079 Trivial change to support GCC's configuration procedure.

10081 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
10082 about inconsistency if the preprocessor is set to give errors for
10083 any warning.

10138 Improve the accuracy of the wording about obsolescence.
10139 From a suggestion by Ian Lance Taylor in
10140 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
10142 2003-09-05 Paul Eggert <eggert@twinsun.com>
10144 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,

10160 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10162 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10164 Add support for newer Fortran dialects. The F77 interface is
10165 unchanged, and continues to support Fortran 77. New FC macros
10166 correspond to all the old F77 macros, with output variables FC,
10167 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10168 available dialect, but older dialects can be specified. There are
10169 new macros AC_FC_SRCEXT to set the source extension, and
10170 AC_FC_FREEFORM to accept free-form source files.

10200 Document problems with timestamp resolution that 'make', 'cp -p', and
10201 'touch -r' have.
10203 2003-08-27 Akim Demaille <akim@epita.fr>
10205 * tests/m4sugar.at (cross_warning): Make sure to enable the
10206 output, so that we can track spurious m4sugar output.
10207 * tests/local.at: Require 2.57.
10208 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that

10263 2003-08-22 Akim Demaille <akim@epita.fr>
10265 Output stack traces in warnings.
10267 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
10268 Replace the former...
10269 (m4_warn): Pass the call stack to _m4_warn.
10270 * bin/autom4te.in: Adjust to output the call stack.
10271 * tests/m4sugar.at (m4@&t@_warn): Adjust.
10273 2003-08-22 Akim Demaille <akim@epita.fr>
10275 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.

10280 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
10281 (&verbose): Remove.
10282 (&getopt): Adjust the note and verb channels, depending upon

10284 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
10285 * bin/autoupdate.in: Adjust.
10286 Use &verb, not &verbose.
10288 2003-08-21 Akim Demaille <akim@epita.fr>
10290 * bin/autoheader.in (&parse_args): Use &parse_warnings and
10291 &parse_WARNINGS.
10292 ($help): Use Autom4te::ChannelDefs::usage.
10293 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10294 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10296 2003-08-21 Akim Demaille <akim@epita.fr>
10298 First stab at preserving warnings between calls to autom4te,
10299 including when the cache is used.
10301 There are still several issues: (i) there are too many runs of m4
10302 (one for include, one for warnings, and some more), (ii) warnings
10303 spreading on several lines are not handled gracefully, (iii) the
10304 code meant to have the call stack display for errors does not work
10305 (its handling should move from m4 to autom4te).
10307 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10308 Use them.
10309 (@preselect): Add m4_warn.
10310 ($exit_status): Remove, use $exit_code.
10311 ($help): Use Autom4te::ChannelDefs::usage.
10312 (&handle_m4): No longer define the m4_warnings.
10313 At each run, extract and report the warnings.
10314 Always cache the result, including if the exit status is on
10315 failure, since if nothing changes, we should result in the same
10316 failure, hence we can use the cache.
10317 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10318 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10319 Remove.
10320 (m4_warn): Redefine as a do-nothing: it is its invocation that
10321 matters, as warnings are now reported via traces.
10322 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10323 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10324 the latter reveals calls to the former.
10326 Adjust the tests.
10328 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
10330 2003-08-21 Akim Demaille <akim@epita.fr>
10332 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
10333 Use them.
10335 2003-08-21 Akim Demaille <akim@epita.fr>
10337 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
10338 forward order.
10339 * lib/Autom4te/ChannelDefs.pm: Doc typos.
10340 (&parse_warnings): Accept a list of warning requests.
10341 (&usage): Return a string, not a side effect.
10342 (cross): New warning category.
10344 2003-08-21 Akim Demaille <akim@epita.fr>
10346 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
10347 (&require_configure_ac): Accept an optional directory argument.
10348 ($configure_ac): Remove.
10349 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
10350 (&catfile): Remove.
10351 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
10352 * bin/autoscan.in: Adjust.
10354 2003-08-20 Akim Demaille <akim@epita.fr>
10356 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
10357 Reported by Alexandre Duret-Lutz.
10359 2003-08-20 Akim Demaille <akim@epita.fr>
10361 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10362 * bin/autom4te: Adjust.
10363 In particular, be Autoconf tools are really silent when properly
10364 working, bind the verbosity of the 'note' channel to $verbose.
10365 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10366 (&xsystem, &contents): Remove, since they are exported by...
10367 * lib/Autom4te/FileUtils.pm: this.
10368 More perldoc.
10369 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
10370 * lib/Autom4te/FileUtils.pm: here.
10372 2003-08-20 Akim Demaille <akim@epita.fr>
10374 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
10375 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
10376 from CVS Automake.
10378 2003-08-20 Akim Demaille <akim@epita.fr>
10380 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
10381 (autom4te-update): New.
10382 * Makefile.cfg (update): Bind autom4te-update.
10384 2003-08-19 Derek Price <derek@ximbiot.com>
10386 * lib/autotest/general.m4: Comment various HELP_* diversions.

10390 package specific options and associated help.
10392 2003-08-19 Akim Demaille <akim@epita.fr>
10394 * config/announce-gen, Makefile.cfg: New.

10396 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
10398 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
10400 * lib/autom4te.in (Automake-preselections): Preselect
10401 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
10402 and m4_sinclude.
10404 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
10406 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...

10408 * doc/autoconf.texi (autom4te Invocation): Mention
10409 Autoconf-without-aclocal-m4.
10411 2003-08-18 Derek Price <derek@ximbiot.com>
10413 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
10414 RUN-IF-PASS optional arguments.

10423 STDOUT & STDERR arguments.
10425 2003-08-14 Derek Price <derek@ximbiot.com>
10427 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
10428 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
10429 shorter column three. Add DESCRIPTION to log file content.
10431 2003-08-13 Derek Price <derek@ximbiot.com>
10433 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
10434 output.

10438 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
10439 (AT_CHECK_NOESCAPE): Move core functionality to...
10440 (_AT_CHECK): ...this new macro.
10442 2003-08-07 Derek Price <derek@ximbiot.com>
10444 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
10445 (AT_CHECK_NOESCAPE): ...to this new macro.
10447 2003-07-31 Paul Eggert <eggert@twinsun.com>
10449 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
10450 in Bash 2.01. Problem reported by Brian Gough in
10451 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.

10455 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
10456 -lcrt1.o, for OS X. (trivial change)
10458 2003-07-07 Paul Eggert <eggert@twinsun.com>
10460 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
10461 inside '#ifndef __cplusplus'. Problem reported by
10462 Bob Friesenhahn.
10464 2003-07-06 Bill Clarke <llib@computer.org>
10466 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
10467 'long', not 'int', for benefit of Sun's recent C++ compilers
10468 (trivial change). See:
10469 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
10470 (This really should be 'intptr_t', not 'long', but that would
10471 take more work.)
10473 2003-06-25 Akim Demaille <akim@epita.fr>
10475 * lib/Makefile.am (autom4te.cfg): Make it read only.
10476 Depend on Makefile since it contains substitutions.
10477 From Paolo Bonzini.
10478 * lib/autom4te.in (args): Add local.at? for Autotest args.
10479 This change was made on autom4te.cfg which is generated.

10485 From Gareth McCaughan.
10487 2003-06-23 Akim Demaille <akim@epita.fr>
10489 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10490 not all of them. This fixes 1. the fact that when testing
10491 Autoconf there are many many config.log, 2. the incorrect use of
10492 top_srcdir to find config.log.
10493 Don't mix the detailed output of failed test with the summary of
10494 failures. Rather, append detailed log afterwards.
10496 2003-06-23 Akim Demaille <akim@epita.fr>
10498 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

10519 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
10520 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
10521 ensuring we add -std1 for full-ANSI.
10523 * doc/autoconf.texi (hdrindex): New macro.
10524 Add index entries for portability of various standard header files.
10526 2003-06-20 Akim Demaille <akim@epita.fr>
10528 * configure.ac: Bump to 2.57b.
10530 2003-06-20 Akim Demaille <akim@epita.fr>

10550 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
10552 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
10553 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
10554 (TEST_SCRIPT): New diversion.

10570 * NEWS, doc/autoconf.texi (Particular Functions),
10571 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
10572 is the inverse of localtime.
10574 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
10576 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
10577 (handle_exec_errors): New function. Work around $! being
10578 altered by WEXITSTATUS.
10579 (xqx, xsystem): Use handle_exec_errors.
10581 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
10583 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
10584 Do not call `_exit()', simply modify `$?'.
10585 (xsystem): Reset $! before running system, and check it afterward.
10586 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
10587 63 for version mismatches.
10589 2003-05-23 Akim Demaille <akim@epita.fr>
10591 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10592 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10593 the middle of a line).
10594 * lib/m4sugar/m4sugar.m4: Likewise.
10595 Remove useless spaces in comments.
10597 2003-05-23 Akim Demaille <akim@epita.fr>
10599 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
10600 exit 63, so that we (or Automake's "missing") can tell the
10601 difference with a plain failure.
10602 * doc/autoconf.texi (Notices): Adjust.
10604 2003-05-23 Akim Demaille <akim@epita.fr>
10606 * Makefile.am, bin/Makefile.am, config/Makefile.am,
10607 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
10608 White spaces cleanup.
10610 2003-05-22 Jim Meyering <jim@meyering.net>
10611 Paul Eggert <eggert@twinsun.com>
10613 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10614 Remove `#include <stdlib.h>' from the list; we should never
10615 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10616 resulting namespace pollution would cause other tests to fail.
10617 Configure scripts run with some older versions of g++ and HP's
10618 aCC would fail due to such an #include. Problems reported by
10619 Matthew Mueller in <http://bugs.debian.org/120704> and by
10620 Keith Bostic in
10621 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10622 In the test, use the test declaration before including <stdlib.h>,
10623 as that's closer to how it'll be used.
10625 2003-05-23 Akim Demaille <akim@epita.fr>
10627 * doc/autoconf.texi (Header Portability): ucred.h.
10628 From Ian Redfern.
10630 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10632 Overhaul Autotest's logging: generate separate log files
10633 in testsuite.dir/NNN/testsuite.log, and append them to
10634 testsuite.log instead of re-running the test verbosely.
10636 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10637 file descriptor, write 0 to at_status_file instead of setting
10638 at_status=0, initialize some new variables (at_status_file,
10639 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10640 to rerun the tests, instead append the at_group_log to the
10641 at_suite_log when a test fails.
10642 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10643 with the AS_MESSAGE_LOG_FD redirected to stdout.
10644 (AT_CLEANUP): save the output status in $at_status_file
10645 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10646 its original place.
10647 (AT_CHECK): since tests are run with a redirected stdout,
10648 and used to be re-run in verbose mode, turn some $at_verbose
10649 into echo, and don't redirect the output of testing stdout
10650 and stderr.
10652 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10653 the name of the debugging directory and information about
10654 its contents.
10656 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10658 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
10659 parameter.

10682 Suggested by Jim Meyering.
10684 2003-05-22 Akim Demaille <akim@epita.fr>
10686 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
10687 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
10688 Reported by Jim Meyering.
10690 2003-05-22 Akim Demaille <akim@epita.fr>
10692 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

10725 2003-05-17 Akim Demaille <akim@epita.fr>
10727 * lib/autoconf/functions.m4: Use the default includes so that
10728 memcmp be declared before being tested.
10729 Reported by Sander Niemeijer.

10748 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10749 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
10750 them uniform, and more robust to Perl special characters.
10751 Reported by Martin Mokrejs.
10753 2003-05-14 Akim Demaille <akim@epita.fr>

10771 and truncate.
10773 2003-05-06 Akim Demaille <akim@epita.fr>
10775 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10776 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10777 by aclocal.m4 is changed it might require the importing of another
10778 m4 extension file, i.e., aclocal must be run.
10780 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
10781 (&parse_args): Use --force with aclocal if required and supported.
10782 (&autoreconf_current_directory): Use &run_aclocal.
10784 2003-05-06 Akim Demaille <akim@epita.fr>

10789 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
10790 argument instead of a file name, so that the request file remains
10791 open during the whole autom4te run.
10792 ($icache_file): New.
10793 (&freeze): Lock the $icache_file.
10795 2003-04-29 Derek Price <derek@ximbiot.com>
10797 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
10798 seperator with m4_append_uniq(). It doesn't work.
10799 (AT_CLEANUP): Add `;' to end of at_help_all.
10800 (AT_INIT): Allow --keywords to be specified more than once. When
10801 grepping $at_help_all for keywords, use the field and keyword
10802 seperators to ensure a complete keyword match. Alter at_prev handling
10803 to support the new --keywords behavior.
10805 2003-04-27 Karl Berry <karl@freefriends.org>
10807 * doc/autoconf.texi: Make the dir entries in the autoconf manual
10808 align better with others. I also made some of the individual
10809 entries on one line, for brevity and to make it easier for me to
10810 sort my dir-example file in the Texinfo distribution :).
10812 2003-04-12 Jim Meyering <jim@meyering.net>

10850 New.
10851 Use them.
10852 * doc/Makefile.am (CLEANFILES): Adjust.
10853 (TEXI2DVI): Make it --batch.
10855 2003-03-31 Derek Price <derek@ximbiot.com>
10857 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
10858 which removed the main loop.
10859 Thanks to Akim Demaille.
10861 2003-03-29 Akim Demaille <akim@epita.fr>
10863 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Skip OS/2's install,

10865 From Ilya Zakharevich.
10867 2003-03-29 Akim Demaille <akim@epita.fr>
10869 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The

10877 header causes problems.
10879 2003-03-28 Akim Demaille <akim@epita.fr>
10881 * tests/torture.at (Configuring subdirectories): Require aclocal
10882 1.4, otherwise the test fails, as it does support configure.ac.
10883 This fixes the "test 40 failed" bug reports.
10885 2003-03-28 Akim Demaille <akim@epita.fr>
10887 * doc/autoconf.texi (C Compiler): `#line' portability.

10915 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
10916 sense. Verbosify the diversion definitions comment.
10918 2003-03-26 Derek Price <derek@ximbiot.com>
10920 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to

10935 #line directives.
10936 * lib/autoconf/lang.m4 (AC_LANG_SOURCE): Fix comment to match this.

10952 * doc/autoconf.texi (Limitations of Make): Remove the section
10953 about `$<' in inference rules, it was a bogus interpretation of
10954 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
10955 Tru64 make in the "target lookup" section.
10956 (Automake): Automake 1.5+ no longer requires special tools to be
10957 present on the developer's host.
10959 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
10961 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set

10975 ${ac_make}.
10977 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
10978 When constructing paths with IFS=:, quote the path. If we're
10979 constructing a DOS-style absolute path, we don't want to split it
10980 on the colon.
10982 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
10983 in description.
10985 2003-02-25 Pavel Roskin <proski@gnu.org>

10995 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
10997 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
10998 to fix a mismatch between example and discussion.
11000 2003-02-24 Kevin Ryde <user42@zip.com.au>
11002 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
11003 format starting with "-".
11005 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>

11008 is not portable inside Makefile.
11010 2003-02-20 Akim Demaille <akim@epita.fr>
11012 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
11013 compiler says yeah, but preproc says nope, compiler is right.
11014 Conversely, prompt the reader to send a bug report to the
11015 maintainers of the package, not of Autoconf.
11017 2003-02-20 Klee Dienes <kdienes@apple.com>
11019 * bin/autoreconf.in (autoreconf_current_directory): Properly
11020 handle an empty aclocal.m4.

11024 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Quote

11026 From Larry Jones.
11028 2002-12-23 Paul Eggert <eggert@twinsun.com>
11030 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11031 innocuous variant befor including <limits.h> or <assert.h>. This
11032 works around a bug reported by Albert Chin: HP-UX 11i
11033 (and earlier versions) have a <limits.h> that declares
11034 gettimeofday and many other functions.
11036 2002-12-03 Paul Eggert <eggert@twinsun.com>
11038 Version 2.57.
11040 * NEWS, configure.ac: Update version.
11042 * doc/fdl.texi: Upgrade to FDL version 1.2.
11044 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
11045 nontrivially in main's body, so that f's external declaration is
11046 not optimized away in AIX. This should fix the bug reported by
11047 Martin Frydl in
11048 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11050 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11051 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11052 defined, to support freestanding compilers. This should fix the
11053 bug reported by Momchil Velkov in
11054 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11056 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11057 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
11058 obsolete AC_CHECK_TYPE. The missing empty arg was reported
11059 by Simon Josefsson in
11060 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
11062 * Makefile.maint (www-gnu): New macro.
11063 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
11064 the location has moved.
11066 2002-12-02 Martin Frydl <martin@systinet.com>
11068 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
11069 \(.*\) match is too long and there is something more to be checked.
11070 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
11072 2002-11-15 Akim Demaille <akim@epita.fr>
11074 Version 2.56.

11080 * configure.ac (AM_INIT_AUTOMAKE): here.
11081 Require 1.7.1.
11083 2002-11-14 Akim Demaille <akim@epita.fr>

11088 Update from masters.
11090 2002-11-14 Akim Demaille <akim@epita.fr>
11092 * Makefile.maint: Sync with Bison, i.e.:
11093 (po-check): Scan .l and .y files instead of the
11094 .c and the .h files that they generate. This fixes the bug
11095 reported by Tim Van Holder in:
11096 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11097 Look for N_ as well as for _. Try to avoid matching #define for
11098 N_ and _.
11099 From Paul Eggert.
11101 2002-11-14 Akim Demaille <akim@epita.fr>
11103 * doc/autoconf.texi (C Compiler): Compiling several files at once.
11104 From Paul Eggert and Albert Chin-A-Young.
11106 2002-11-14 Akim Demaille <akim@epita.fr>
11108 * doc/autoconf.texi (C Compiler): Solitary backslashes.
11109 From Paul Eggert and Albert Chin-A-Young.
11111 2002-11-14 Kevin Ryde <user42@zip.com.au>
11113 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11114 than assigning in main, to avoid HP cc +O3 optimizing it away.
11116 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
11118 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11119 option. Process --recheck after parsing all options. Pass -q
11120 option to configure on --recheck.
11121 (AC_OUTPUT): Pass -q from configure to config.status.
11122 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
11123 arguments to record.
11124 * doc/autoconf.texi (config.status Invocation): Document
11125 config.status -q option.
11127 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11129 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11130 Makefile.in if Makefile.am exists.
11131 (output): Strip `.am' from Makefiles. Don't
11132 output AC_CONFIG_FILES if no Makefiles were found.

11143 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
11144 declaration in extern "C" too.
11145 Reported by Roberto Bagnara.
11147 2002-11-06 Akim Demaille <akim@epita.fr>
11149 * tests/torture.at (Configuring subdirectories): Don't use grep
11150 -w.

11152 Reported by Ezra Peisach.
11154 2002-11-05 Akim Demaille <akim@epita.fr>
11156 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11157 Remove.
11158 We _have_ to stop using the old compatibility scheme that tried to
11159 avoid useless backslashes because Libtool 1.4.3 contains a
11160 AC_DEFINE([error_t], [int],
11161 [Define to a type to use for \`error_t' if it is not
11162 otherwise available.])
11163 We _have_ to quote the single quote and backslashes with \. The
11164 old compatibility scheme saw that ` was backslashed, and therefore
11165 did not quote the single quote. Hence before this patch, Autoconf
11166 was not compatible with Libtool.
11168 2002-11-04 Paul Eggert <eggert@twinsun.com>
11170 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
11171 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
11172 LC_NAME, LC_PAPER, LC_TELEPHONE.

11175 2002-11-04 Akim Demaille <akim@epita.fr>
11177 Version 2.54c.

11181 * config/texinfo.tex: Update.

11186 from...
11187 (&autoreconf): here.

11189 Support -m/--make.

11206 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
11208 2002-10-31 Akim Demaille <akim@epita.fr>
11210 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
11211 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
11212 Make variable, not a shell variable.
11213 Suggested by Bruno Haible.
11215 2002-10-31 Akim Demaille <akim@epita.fr>
11217 * bin/autom4te.in (load_configuration): Reject #args out of any
11218 language.
11220 2002-10-31 Akim Demaille <akim@epita.fr>

11238 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
11239 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
11240 Problem reported by Bruno Haible.
11242 2002-10-29 Akim Demaille <akim@epita.fr>
11244 * doc/autoconf.texi (Header Templates): Put also in words what the

11513 Quote for Perl, not sh.
11514 * bin/autoheader.in: When $debug, report the file which is
11515 `do'ne.
11516 * tests/tools.at (autom4te, autoheader): Exercise @bar, not merely
11517 `@', to tickle Perl's lists.
11518 Reported by Carlos Velasco.
11520 2002-10-18 Akim Demaille <akim@epita.fr>
11522 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that
11523 missing included files _are_ errors.
11524 Thanks to Alexandre Duret-Lutz.
11525 * tests/tools.at (autom4te cache): Adjust.
11526 * tests/atspecific.m4 (AT_CHECK_AUTOM4TE): New.

11528 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
11529 Adjust.
11530 * tests/tools.at (autom4te): Now it does exit 1.
11532 2002-10-17 Akim Demaille <akim@epita.fr>
11534 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.
11535 Fixes the `AC_ARG_VAR' test failures.
11536 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Don't use cmp.
11537 * lib/freeze.mk (check-forbidden-patterns): New.
11538 * lib/autoconf/Makefile.am, lib/autotest/Makefile.am
11539 * lib/m4sugar/Makefile.am (check-local): Use it to catch `cmp'.
11540 * doc/autoconf.texi (Limitations of Usual Tools): HP-UX' cmp and
11541 /dev/null.
11542 Reported months ago by H. Merijn Brand.
11544 2002-10-17 Akim Demaille <akim@epita.fr>
11546 * tests/tools.at (autoheader): Put randoms `@' to stress Perl.
11548 2002-10-16 Paul Eggert <eggert@twinsun.com>
11550 * Makefile.maint (wget_files): Remove ansi2knr.c.
11551 (ansi2knr.c-url_prefix): Remove.
11553 2002-10-16 Akim Demaille <akim@epita.fr>
11555 Because of caching, some files that no longer exist and are no
11556 longer required can still cause errors.
11557 Reported by Alexandre Duret-Lutz.
11559 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
11560 to frozen files in @ARGV, as @ARGV must remain being a list of
11561 files. Rather, at M4 call sites, use this...
11562 (&files_to_options): New function.
11563 (&freeze): Use &error.
11564 (&up_to_date): If a file that was included according to the cache
11565 is no longer there, then the output is out dated.
11566 (&main): Don't even check whether a file is up to date is anyway
11567 --force is given.
11568 * tests/tools.at (autom4te cache): New.
11570 2002-10-16 Akim Demaille <akim@epita.fr>
11572 * bin/autoconf.as: Kill dead options.
11573 * bin/autoupdate.in (&parse_args): Kill old options.
11574 * bin/autoreconf.in (&parse_args): Remove dead options.
11575 Factor some code.
11576 (&autoreconf): Report the directories we enter *and leave*, so
11577 that error messages can be easily located, and use GNU Make
11578 format, so that Emacs' compile mode understands us.
11579 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
11580 if some file was changed instead of `print'.
11581 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
11582 (&parse_args): Remove the dead options.
11583 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
11584 autoheader's quiet mode.
11585 (AT_CHECK_AUTOUPDATE): Likewise.
11586 * tests/tools.at (autoupdate): Adjust.
11587 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
11589 2002-10-11 Akim Demaille <akim@epita.fr>
11591 No longer use CPP to check for the existing of headers: use CC to
11592 check for compilability.
11594 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
11595 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
11596 (_AC_CHECK_HEADER_NEW): Rename as...
11597 (AC_CHECK_HEADER): this.
11599 * lib/autotest/general.m4 (AT_INIT): Include the failed test
11600 numbers in the Subject suggestion.
11602 2002-10-11 Akim Demaille <akim@epita.fr>
11604 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
11605 Suggest using AC_CHECK_DECLS instead.
11607 2002-10-11 Akim Demaille <akim@epita.fr>
11609 * tests/torture.at (AC_ARG_VAR): Have configure report the value
11610 of `precious'.
11612 2002-10-11 Akim Demaille <akim@epita.fr>
11614 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
11615 file name to enable parallel executions.
11616 From Sam Varshavchik.
11618 2002-10-08 Akim Demaille <akim@epita.fr>
11620 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11621 aclocal invocation, as Gettext macros might not be visible to
11622 aclocal.
11623 Instead of blindly running autopoint, scan configure.ac (not the
11624 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11625 Reported by Paul D. Smith.
11627 2002-10-08 Paul Eggert <eggert@twinsun.com>
11629 Work around problems found when POSIXLY_CORRECT=1 is set.
11630 None of this seems to have anything to do with POSIX, really,
11631 but it's how Perl getopt works.
11632 * bin/autom4te.in (parse_args): Configure GetOpt with
11633 "permute", too.
11634 * doc/autoconf.texi (Invoking autom4te):
11635 --warning -> --warnings.
11636 * lib/autom4te.in: --warning -> --warnings.
11638 2002-09-28 Akim Demaille <akim@epita.fr>
11640 * doc/autoconf.texi (autom4te.cache): New section.
11642 2002-09-28 Akim Demaille <akim@epita.fr>

11652 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11653 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
11655 2002-09-28 Akim Demaille <akim@epita.fr>
11657 * tests/torture.at (Configuring subdirectories): Be robust to
11658 users who use config.site to require for a cache: in this case,
11659 the two last configure runs, using two different sets of
11660 arguments, trigger a legitimate error.
11662 2002-09-28 Akim Demaille <akim@epita.fr>
11664 * tests/m4sh.at (Functions Support, Functions and return Support):
11665 New.

11669 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and

11671 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
11672 (autom4te): Specify that the sources are in the $srcdir.
11673 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11675 2002-09-28 Akim Demaille <akim@epita.fr>
11677 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
11678 (tm_zone): Move their rules to...
11679 * lib/autoconf/types.m4: here, using AN_ macros.
11680 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
11681 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
11682 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
11683 * lib/autoconf/programs.m4: here.

11686 Use it.

11690 * lib/autoconf/autoscan.m4: New file.
11691 * lib/autoconf/autoconf.m4: Include it.
11692 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
11693 that were listed in the original autoscan.list.
11694 * lib/autoconf/headers.m4: Similarly with headers.
11695 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
11696 (.m4.m4f): Don't pass --prepend-include, since that's done by
11697 tests/autom4te itself.
11698 * lib/autoscan/Makefile.am: Include freeze.mk.
11699 (autoscan.list): New target --this file is no longer a source.
11700 (autoscan.pre): New file.
11702 2002-09-28 Akim Demaille <akim@epita.fr>
11704 * bin/autoscan.in (@kinds): Make them singular.
11705 Adjust all uses.
11706 (&init_tables): When --debug, report the list of rules to ease
11707 tracking changes in autoscan.list.
11708 * lib/autoscan/autoscan.list (function): Strip comments, sort.
11710 2002-09-28 Akim Demaille <akim@epita.fr>
11712 * lib/autoscan/functions, lib/autoscan/headers,
11713 * lib/autoscan/identifiers, lib/autoscan/makevars,
11714 * lib/autoscan/programs: Merge into...
11715 * lib/autoscan/autoscan.list: this.
11716 * bin/autoscan.in (&init_tables): Adjust.
11718 2002-09-28 Akim Demaille <akim@epita.fr>
11720 * lib/autoscan/functions, lib/autoscan/headers,
11721 * lib/autoscan/identifiers, lib/autoscan/makevars,
11722 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
11723 `functions' line is now prefixed with `function:'.
11724 * bin/autoscan.in (&init_tables): Adjust.
11726 2002-09-28 Akim Demaille <akim@epita.fr>
11728 From now on, autoscan files must always map a macro name to a
11729 word: there is no `default' macro for autoscan.
11731 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11732 all.
11733 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
11734 explicit.
11736 2002-09-28 Akim Demaille <akim@epita.fr>
11738 * bin/autoscan.in (%c_keywords): Remove.
11739 (&used): Keep only track of the words we might be interested in.
11740 (&output_kind): It is no longer needed to look for non active
11741 checks.
11743 2002-09-27 Akim Demaille <akim@epita.fr>
11745 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

11763 (&parse_args): Drop obsolete undocumented options.
11764 (&output_kind): Output warnings.
11765 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
11766 (getwd): Trigger a warning.
11768 2002-09-26 Akim Demaille <akim@epita.fr>
11770 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
11771 Reported by Ralf Corsepius.
11772 * doc/autoconf.texi (autoreconf Invocation): Likewise.
11774 2002-09-26 Akim Demaille <akim@epita.fr>
11776 Single suffix rules and seperated dependencies are not portable.

11780 Separated Dependencies'.
11781 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11782 (ifnames, autoscan, autom4te): Un-factor into several rules.
11784 2002-09-25 Paul Eggert <eggert@twinsun.com>
11786 * BUGS (Interoperability bugs): New section. Mention libtool
11787 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
11789 2002-09-24 Paul Eggert <eggert@twinsun.com>
11791 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
11792 make handles suffix-rules differently from GNU make.
11794 * bin/Makefile.am (SUFFIXES, .in): Remove.
11795 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):

11804 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
11806 2002-09-13 Paul Eggert <eggert@twinsun.com>
11808 * doc/autoconf.texi (Particular Headers): Remove obsolete
11809 reference to `struct timezone' in the description of
11810 AC_HEADER_TIME.
11812 2002-09-13 Akim Demaille <akim@epita.fr>
11814 Version 2.54.

11817 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
11818 * Makefile.am: Adjust.
11820 2002-09-13 Akim Demaille <akim@epita.fr>
11822 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
11823 reading config.log when the compiler is rejected.
11824 Suggested by Guido Draheim.
11826 2002-09-13 Akim Demaille <akim@epita.fr>
11828 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
11829 (chdir_init) might hang when stat'ing mounted directories.
11830 Reported by Vance Shipley.
11832 2002-09-12 Akim Demaille <akim@epita.fr>
11834 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
11835 the lists.
11837 2002-09-12 Akim Demaille <akim@epita.fr>
11839 * doc/autoconf.texi (Defining Symbols): Present two different
11840 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
11841 difference between 1 argument calls, and 2-3 argument calls.
11843 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
11845 * doc/autoconf.texi: Review grammar and punctuation.

11850 grammatical typos.
11851 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
11852 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
11853 is obsolescent.
11855 2002-09-11 Akim Demaille <akim@epita.fr>
11857 * doc/autoconf.texi (Questions): Rename as...
11858 (FAQ): this.

11873 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
11874 `duplicates', since the algorithm was too naive and could keep
11875 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
11876 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
11877 Reported by Ralf Corsepius.
11878 * tests/torture.at (Configuring subdirectories): Exercise these
11879 cases.
11881 2002-09-09 Akim Demaille <akim@epita.fr>
11883 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
11884 looking for a replacement file.
11885 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
11886 directory is relative.
11887 * doc/autoconf.texi (Generic Functions): Clarify the replacement

11899 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11900 (ifnames, autoscan, autom4te): Since we don't only depend on
11901 configure.ac variables (such as VERSION etc.), but also on prefix
11902 and so forth, depend on Makefile, not configure.ac.
11903 Reported by Alexandre Duret-Lutz.
11904 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11906 2002-09-05 Kevin Ryde <user42@zip.com.au>
11908 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
11909 doesn't seem to be confined to ia64, just say "some versions".
11911 2002-09-04 Akim Demaille <akim@epita.fr>
11913 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
11914 Automake 1.6c.
11915 * Makefile.am (maintainer-clean-local): Remove.
11916 (MAINTAINERCLEANFILES): Remove COPYING.
11918 2002-09-03 Paul Eggert <eggert@twinsun.com>

11922 Brinkmann.
11924 2002-09-03 Akim Demaille <akim@epita.fr>
11926 * configure.ac: Bump to 2.53d.
11927 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11928 as of today, on Automake's team suggestion.
11930 2002-09-03 Akim Demaille <akim@epita.fr>
11932 Version 2.53c.
11934 2002-09-02 Akim Demaille <akim@epita.fr>

11940 2002-09-02 Jim Meyering <meyering@lucent.com>
11942 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11943 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11944 Also, tweak grammar: s/make sure to/be sure to/.
11946 2002-09-02 Paul Eggert <eggert@twinsun.com>
11948 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11949 directory names are generally preferable to physical names.
11951 2002-09-02 Akim Demaille <akim@epita.fr>
11953 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11954 Reported by Raja R. Harinath.
11955 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11956 * bin/autoupdate.in: Use error instead of die.
11958 2002-09-01 Paul Eggert <eggert@twinsun.com>
11960 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11961 ordinary shell concatenation rather than echo+tr+sed command that
11962 runs afoul of a long-line-related sed bug in Solaris 8.
11964 * bin/autoheader.in (parse_args): --warning -> --warnings.
11966 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11967 stdout, as traditional "ls" does.
11968 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11969 _AC_COMPILER_EXEEXT_O): Likewise.
11970 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11972 * bin/autoconf.as: Add --prepend-include option. This patch was
11973 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11974 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11976 * bin/autoconf.in, configure: Regenerate.
11978 * doc/autoconf.texi (Special Shell Variables): Mention
11979 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11981 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
11982 MAILPATH and set PS1, PS2, PS4 to default values, to work
11983 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11984 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11985 the Autoconf documentation specifies; fall back to "unset" only if
11986 this fails. Use a shell for-loop for this rather than an m4 loop,
11987 to shorten the output script.
11989 2002-08-30 Paul Eggert <eggert@twinsun.com>
11991 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
11992 1003.1-2001's requirements for CDPATH. Give a simpler workaround
11993 for the CDPATH problem. Document PWD.
11994 (Limitations of Builtins): Document the problem that "cd $foo" and
11995 "ls $foo" may refer to different directories in shells conforming
11996 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
11997 example, since the old example is now out of date.
11999 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12000 FOO" and "ls FOO" talk about different directories; this catches
12001 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12002 spaghetti.
12004 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12005 of rolling our own unset.
12006 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12007 in practice we needn't worry about CDPATH if unset doesn't work.
12009 * Makefile.in, aclocal.m4, bin/Makefile.in,
12010 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12011 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12012 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12013 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12014 tests/Makefile.in: Regenerate with Automake 1.6.3.
12016 * config/config.guess, config/config.sub, config/mkinstalldirs:
12017 Update.
12019 * configure: Regenerate with self.
12021 2002-08-30 Kevin Ryde <user42@zip.com.au>
12023 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12024 default output.
12026 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>

12029 failure.
12031 2002-08-29 Akim Demaille <akim@epita.fr>
12033 * lib/Autom4te/General.pm (&xqx): New.
12034 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12035 hand, which is not portable.
12036 (&error): New.
12037 * bin/autom4te.in: Use them.
12038 Use &error instead of die.
12039 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12040 Adjust.
12042 2002-08-17 Paul Eggert <eggert@twinsun.com>
12044 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12045 default list of compilers to try, since it was long ago superseded
12046 by the ksh fc builtin. Suggested by Steven G. Johnson.
12048 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12050 * doc/autoconf.texi (Invoking autom4te): End the option table,
12051 fixing a bug introduced by the previous patch.
12052 (Limitations of Make): Add a 'target lookup' subentry in the
12053 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12055 2002-07-29 Mark D. Roth <roth@feep.net>
12057 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12058 options and use $AUTOM4TE_PATH.
12059 * doc/autoconf.texi: Remove documentation of autom4te
12060 --include-envvar and --site-macro-subdir options and document
12061 use of $AUTOM4TE_PATH.
12062 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12063 arguments from each language section.
12065 2002-07-29 Paul Eggert <eggert@twinsun.com>
12067 * doc/install.texi: Include copyright symbol in copyright notice.
12069 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12070 Replace with:
12071 (AM_MAKEINFOFLAGS): New macro.
12072 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12073 * Makefile.am (INSTALL): Use the new macros.
12074 Use -o rather than --output, since "missing" does not grok --output.
12076 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12078 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12079 comments do not always work. Never trust the exit status of
12080 `make -k'.
12082 2002-07-24 Kevin Ryde <user42@zip.com.au>
12084 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12085 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12087 2002-07-23 Paul Eggert <eggert@twinsun.com>
12089 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12090 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12091 apparently treats PATH="nonexistent" as if it contained ".".
12092 Bug reported by Stefan `Sec' Zehl.
12094 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12096 * doc/autoconf.texi (Limitations of Make): Mention the special

12113 2002-07-18 Akim Demaille <akim@epita.fr>
12115 Version 2.53b.
12117 2002-07-18 Akim Demaille <akim@epita.fr>
12119 * config/config.guess, config/config.sub: Update.

12149 * lib/Autom4te/General.pm (find_file): Browse the directories in
12150 the order they are given.

12211 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
12213 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
12214 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,

12216 so that Emacs setups GNU style for perl-mode and cperl-mode.
12218 2002-06-27 Paul Eggert <eggert@twinsun.com>
12220 * config/install-sh: Quote $src. Prefer || to test's -o option,
12221 as per "Limitations of Builtins".
12222 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
12223 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
12225 * tests/mktests.sh: Use grep instead of fgrep, as per
12226 "Limitations of Builtins".
12228 2002-06-15 Paul Eggert <eggert@twinsun.com>
12230 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
12231 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
12232 so that we consistently test the just-built programs.
12233 * tests/wrappl.as: Likewise.
12235 2002-06-12 Paul Eggert <eggert@twinsun.com>
12237 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
12238 name, so that symlinks to 'autoconf' work properly. Bug reported
12239 by Bruno Haible.
12240 * bin/autoheader.in (AUTOM4TE): Likewise.
12241 * bin/autoreconf.in (autoconf, autoheader): Likewise.
12242 * bin/autoscan.in (autom4te): Likewise.
12243 * bin/autoupdate.in (autom4te): Likewise.
12245 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
12246 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
12247 on Solaris 2.5.1.
12249 2002-06-11 Andreas Schwab <schwab@suse.de>
12251 * doc/autoconf.texi: Add more dir entries.
12253 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
12255 * bin/autom4te.in ($cache): Don't define using `$me', the name
12256 of the cache should not depend on the name under which autom4te
12257 was installed.
12259 2002-06-07 Akim Demaille <akim@epita.fr>
12261 * tests/tools.at (autoconf: forbidden tokens, basic)
12262 (autoconf: forbidden tokens, exceptions): Adjust to the change of
12263 words in autom4te.in.
12265 2002-06-07 Peter Eisentraut <peter_e@gmx.net>

12273 rename as...
12274 (AC_REPLACE_FNMATCH): this.
12275 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
12276 AC_FUNC_FNMATCH_GNU.
12278 2002-06-07 Akim Demaille <akim@epita.fr>
12280 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
12281 Rosetta Stone for Unix.
12283 2002-06-07 Akim Demaille <akim@epita.fr>
12285 * bin/autom4te.in (warn_forbidden): When rejecting a token,
12286 suggest m4_pattern_allow.
12287 Suggested by Adam J. Richter.
12289 2002-06-07 Akim Demaille <akim@epita.fr>
12291 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
12292 ac_config_libobj_dir.
12293 (AC_CONFIG_LIBOBJ_DIR): New.
12294 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
12295 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
12296 Use ac_config_libobj_dir to find the replacement files.
12297 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
12298 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
12299 (AC_REPLACE_FNMATCH_GNU): these.

12302 * tests/mktests.sh (ac_exclude_list): Don't check
12303 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
12305 2002-06-06 Paul Eggert <eggert@twinsun.com>
12307 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
12308 if ln doesn't work.
12309 * NEWS: Likewise.
12310 * doc/autoconf.texi (Configuration Links): Likewise.
12311 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
12313 2002-06-05 Paul Eggert <eggert@twinsun.com>
12315 * config/config.guess, config/config.sub, config/texinfo.tex:
12316 Update from masters.
12318 2002-05-29 Paul Eggert <eggert@twinsun.com>
12320 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.

12333 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
12334 * doc/autoconf.texi (Particular Programs): Document them.
12335 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
12336 * NEWS: Likewise.
12338 2002-05-27 Paul Eggert <eggert@twinsun.com>
12340 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
12341 * NEWS, doc/autoconf.texi (Particular Types): Document it.
12342 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
12343 instead of AC_MBSTATE_T, which never existed.
12345 2002-05-23 Akim Demaille <akim@epita.fr>
12347 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
12348 version of Autoconf that is discussed.
12350 2002-05-22 Paul Eggert <eggert@twinsun.com>
12352 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
12353 from the default list of compilers to try. Suggested by
12354 Kate Hedstrom.
12355 * NEWS: Document the above.
12356 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
12358 2002-05-17 Paul Eggert <eggert@twinsun.com>
12360 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
12361 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
12362 This improves on an earlier suggestion by H. Peter Anvin.
12364 2002-05-16 Paul Eggert <eggert@twinsun.com>
12366 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12367 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12368 Both macros now accept an optional source-dir arg.
12369 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12371 * NEWS: Document this.
12372 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12374 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12375 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12376 not for GNU extensions; this undoes part of the 2000-11-03 change,
12377 reverting to 2.13-compatible behavior.
12378 Add new optional argument DIR.
12379 (AC_FUNC_FNMATCH_GNU): New macro.
12381 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
12383 2002-05-08 Paul Eggert <eggert@twinsun.com>
12385 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12386 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12387 and it causes a 'test' syntax error if it fails.
12388 Bug reported by Stephen Gildea.
12390 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12391 If prototypes are supported, use them to check this at compile-time,
12392 instead of trying to check it at run-time. If we must do a run-time
12393 check, assume that setvbuf is standard when cross-compiling, as
12394 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12395 Bug reported by Paul D. Smith.
12397 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12398 argument specifying location of getloadavg.c. This removes a
12399 FIXME. This idea was taken from Jim Meyering's implementation in
12400 textutils.
12401 * doc/autoconf.texi (Particular Functions): Document this.
12402 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12403 that's what the code does; this fixes a bug reported by
12404 Paul D. Smith.
12406 2002-05-03 Akim Demaille <akim@epita.fr>
12408 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12409 autopoint instead of gettextize.
12410 ($uses_alocal): Rename as...
12411 ($uses_aclocal): this.
12412 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12413 Suggested by Bruno Haible.
12415 2002-05-03 Akim Demaille <akim@epita.fr>
12417 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12419 2002-04-29 Paul Eggert <eggert@twinsun.com>
12421 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12422 files to be 1 second older; just set them to be the same time.
12423 Also, sleep 1 second after the first aclocal, to work around
12424 problems with sub-second time stamps on the input files.
12426 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12428 * doc/autoconf.texi: Mention "set -e -x" lossage
12429 under node "Limitations of Builtins".
12431 2002-04-29 Akim Demaille <akim@epita.fr>
12433 * doc/install.texi: Better wording for setting variables when
12434 running configure.
12435 From Christian Cornelssen.
12437 2002-04-29 Akim Demaille <akim@epita.fr>
12439 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12440 of lack of $LINENO support, then the test will compare the $LINENO
12441 in testsuite vs. the lineno in the test file. This is wrong, of
12442 course.
12443 Be sure to protect it.
12444 Reported by Patrick Welche.
12446 2002-04-25 Akim Demaille <akim@epita.fr>
12448 * doc/autoconf.texi (Obsolete Macros): Typo.
12449 Reported by Vladimir Volovich.
12451 2002-04-25 Akim Demaille <akim@epita.fr>
12453 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12454 than some of the input files, hence, on the second run of aclocal,
12455 if some of its input are younger, make them older.
12456 Suggested by Paul Eggert.
12458 2002-04-25 Akim Demaille <akim@epita.fr>
12460 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
12461 Thanks to Paul Eggert.
12463 2002-04-25 Akim Demaille <akim@epita.fr>
12465 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
12466 and ac_subst_vars be sh variables containing the list of
12467 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12468 DEFAULT diversion.
12469 (_AC_INIT_PREPARE): Use them to log them.
12470 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12471 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12472 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12473 _AC_SUBST_FILES and _AC_SUBST_VARS.
12474 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12476 2002-04-24 Akim Demaille <akim@epita.fr>
12478 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12479 autoheader, so that automake does not complain about a missing
12480 config.h.in that was to be created.
12482 2002-04-23 Akim Demaille <akim@epita.fr>
12484 * bin/autoheader.in (parse_args): --warning takes an argument.

12500 2002-04-22 Akim Demaille <akim@epita.fr>
12502 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
12503 comma.
12504 Reported by Gregory Giannoni.
12506 2002-04-22 Akim Demaille <akim@epita.fr>
12508 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
12509 Fixes false failures on Darwin.

12534 Minor spelling and grammar fixes.
12536 * doc/autoconf.texi: Follow the outline suggested in the GNU
12537 Sample Texts sections of the Texinfo 4.2 manual. Most
12538 importantly, this makes sure that the copyright notices appear in
12539 all output formats. You probably need Texinfo 4.2 to generate
12540 the manual now.
12542 Fix some bugs when using "$@" when there might be zero positional
12543 arguments in cases where this matters.

12566 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
12568 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

12578 workaround for ${1+"$@"}.
12579 * doc/autoconf.texi (Shell Substitutions): Explain it.
12580 From Oliver Kiddle and Peter Stephenson.
12582 Have M4sh perform minimal shell sanitizing.
12584 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
12585 part into...
12586 (_AS_PREPARE): this new macro.
12587 (AS_PREPARE): New.
12588 (AS_INIT): Invoke AS_SHELL_SANITIZE.
12589 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
12591 Adjust Autoconf and Autotest.
12593 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12594 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
12595 * lib/autotest/general.m4 (AT_INIT): Likewise.
12596 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
12597 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
12598 AS_SHELL_SANITIZE.
12600 Use this M4sh to generate Autoconf's shell scripts.
12602 * tests/wrapsh.as: New, precursor of wrapsh.in.
12603 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
12604 on Autotest and M4sh.
12605 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
12606 (wrapsh.in): New target.
12607 * bin/autoconf.as: New, precursor of autoconf.in.
12608 (autoconf.in): New target.
12610 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

12613 with indented comments in rules.
12615 2002-04-09 Andreas Schwab <schwab@suse.de>
12617 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
12618 ac_top_builddir when setting ac_abs_top_builddir.
12620 2002-04-06 Kevin Ryde <user42@zip.com.au>
12622 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
12623 (Portable Shell): Cross reference to Systemology.
12625 2002-04-05 Akim Demaille <akim@epita.fr>
12627 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
12628 directories when descending in a SUBDIRS.
12629 Reported by Ezra Peisach.
12631 2002-04-04 Andreas Schwab <schwab@suse.de>
12633 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
12634 contains no literal separators.
12636 2002-04-03 Akim Demaille <akim@epita.fr>
12638 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
12639 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
12640 Use dnl, not the KILL diversion.
12641 Extracted from...
12642 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12643 (AC_CONFIG_LINKS): here.
12644 Adjust.
12645 Don't use the KILL diversion, as it kills spurious output, which
12646 results in failures being hidden.
12647 Use m4_defn where appropriate.
12648 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12649 after the second argument.
12650 Use m4_defn.
12651 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12652 syntax, as it is provided by M4sugar.
12653 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
12655 2002-04-03 Andreas Schwab <schwab@suse.de>
12657 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not

12661 aclocal.

12668 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
12669 (_AC_COMPILER_OBJEXT): Use them.
12670 Fixes Debian #138666.
12672 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
12674 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
12676 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
12677 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
12678 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
12679 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
12680 (AC_C_CONST): Same.
12681 (AC_C_INLINE): Same.
12682 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
12683 * doc/autoconf.texi, NEWS: Document.
12684 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
12685 AC_C_CROSS.
12687 2002-04-02 Akim Demaille <akim@epita.fr>

12692 2002-03-28 Kevin Ryde <user42@zip.com.au>
12694 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12695 to avoid versions of HP C which don't allow that.
12697 2002-03-27 Paul Eggert <eggert@twinsun.com>
12699 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
12700 (AS_SHELL_SANITIZE): Invoke it.
12701 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
12703 2002-03-26 Akim Demaille <akim@epita.fr>
12705 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
12707 2002-03-26 Akim Demaille <akim@epita.fr>
12709 * doc/autoconf.texi (Introduction): The GNATS base moved.
12711 2002-03-25 Paul Eggert <eggert@twinsun.com>
12713 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12714 as POSIX requires, as it doesn't work with Zsh.
12715 * doc/autoconf.texi (Assignments): Document the problem.
12717 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12719 * doc/autoconf.texi (Limitations of Make): Mention more issue
12720 about VPATH, overriding of macros in sub-makes, and handling of
12721 SHELL.
12723 2002-03-21 Paul Eggert <eggert@twinsun.com>
12725 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12726 problem with here-document buffer boundaries.
12728 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12729 when reinvoking the shell, to work around problems with installers
12730 who put strange things like "cd" commands in their environments.
12732 2002-03-19 Akim Demaille <akim@epita.fr>
12734 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
12735 From Aaron Ucko.
12737 2002-03-19 Akim Demaille <akim@epita.fr>
12739 * bin/autoscan.in (scan_file): Specify the location in `&used'
12740 invocations.
12741 From Nicolas Joly.
12743 2002-03-19 Akim Demaille <akim@epita.fr>
12745 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
12746 From Nishio Futoshi.
12748 2002-03-19 Akim Demaille <akim@epita.fr>
12750 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
12752 2002-03-18 Paul Eggert <eggert@twinsun.com>
12754 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
12755 (Limitations of Usual Tools): Add mkdir section.
12757 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12758 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12759 back on AS_DIRNAME to compute prefixes otherwise; this is
12760 roughly what mkinstalldirs does. That way, we need not have
12761 our own filename disassembler. The old disassembler did not
12762 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12764 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12765 Create at_test_all by a series of assignments,
12766 not by a single assignment of a long string. The latter causes ksh
12767 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12768 presumably because of a buffer overrun.
12770 2002-03-14 Paul Eggert <eggert@twinsun.com>
12772 * lib/autotest/general.m4 (at_times_skip):
12773 Renamed from at_times. Now a boolean.
12774 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12775 says 'times: not found'.
12777 2002-03-14 Akim Demaille <akim@epita.fr>
12779 * bin/autoreconf.in (&study_gettextize): New.
12780 (&autoreconf): Handle newest gettextize.
12781 Rerun aclocal if needed.
12782 Suggested by Andreas Schwab.
12784 2002-03-13 Akim Demaille <akim@epita.fr>
12786 * doc/autoconf.texi (Special Shell Variables): More about IFS.

12791 Add information about stdint.h and inttypes.h from Paul Eggert.
12793 2002-03-13 Akim Demaille <akim@epita.fr>
12795 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
12796 -p'.
12797 From Bob Proulx.
12799 2002-03-12 Akim Demaille <akim@epita.fr>
12801 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
12802 m4_require.
12804 2002-03-11 Andreas Schwab <schwab@suse.de>
12806 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
12807 does not do it if --with-lispdir is given.
12809 2002-03-08 Akim Demaille <akim@epita.fr>
12811 Version 2.53.
12813 2002-03-08 Akim Demaille <akim@epita.fr>
12815 * doc/autoconf.texi (Subdirectories): Clarify that the
12816 subdirectory should exist.
12818 2002-03-08 Akim Demaille <akim@epita.fr>
12820 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
12822 2002-03-08 Akim Demaille <akim@epita.fr>
12824 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
12825 aliases the actual variables, and modifications of the former
12826 affect the latter.
12828 2002-03-08 Akim Demaille <akim@epita.fr>
12830 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
12831 because of C-c: have m4 output in tmp files, then mv them.
12833 2002-03-08 Akim Demaille <akim@epita.fr>
12835 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

12845 * doc/autoconf.texi (Specifying Names): Clarification suggested by
12846 Kevin Ryde.
12848 2002-03-05 Akim Demaille <akim@epita.fr>
12850 Version 2.52i.
12852 2002-03-04 Akim Demaille <akim@epita.fr>
12854 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
12855 * lib/autoconf/general.m4 (AC_INIT): More informative error
12856 message for LIBOBJ.
12858 2002-03-04 Akim Demaille <akim@epita.fr>
12860 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
12861 parallel builds.
12863 2002-03-04 Akim Demaille <akim@epita.fr>
12865 * doc/autoconf.texi (Transforming Names): Equality between target
12866 and host is irrelevant.
12867 (Specifying Names, Canonicalizing): Remove all references to the
12868 backward compatibility hooks. Rather, collect them all into...
12869 (Hosts and Cross-Compilation): this new section.
12870 * doc/install.texi (System Type): Ditto.
12871 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12872 that `--host' implies cross-compilation.
12874 2002-03-04 Akim Demaille <akim@epita.fr>
12876 * doc/autoconf.texi (Evaluation Macros): New.
12877 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
12878 useless.
12879 (_m4_foreach): Define the variant with immediate evaluation so
12880 that it contains exactly the items, not an expression which
12881 evaluation is the current item.
12882 (m4_re_string, m4_re_word): Don't over quote them.
12884 2002-03-04 Akim Demaille <akim@epita.fr>
12886 Instead of having stacking `shift's evaluated at the end, let
12887 `foreach' loops immediately evaluate them.
12889 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12890 $*. This is the n-th time I change my mind, but hopefully this is
12891 the last...
12892 (m4_lquote): New.
12893 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12894 efficient.
12895 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12896 it was only a hack for m4_text_wrap.
12897 (m4_car2): Remove, replaced by...
12898 (m4_cdr): New.
12899 (_m4_foreach): Adjust.
12900 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12901 m4_bpatsubst for clarification.
12903 2002-03-04 Akim Demaille <akim@epita.fr>
12905 * doc/autoconf.texi (Changequote is Evil): New.

12932 From Akinori Musha.
12934 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
12936 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
12937 translate \r\n to \n.
12939 2002-02-07 Akim Demaille <akim@epita.fr>
12941 Version 2.52h.
12943 2002-02-07 Akim Demaille <akim@epita.fr>

12952 Fix Autoconf PR/207:
12953 AC_PREFIX_PROGRAM fails with dashed program names
12955 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
12956 variable when looking for the prefix program.
12957 Now it also works for shell variables.
12959 2002-02-07 Akim Demaille <akim@epita.fr>
12961 * doc/autoconf.texi (Limitations of Builtins): More about
12962 case/esac.
12964 2002-02-06 Akim Demaille <akim@epita.fr>
12966 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
12967 case/esac, some shells don't support it.
12968 Reported by Zack Weinberg.
12969 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
12971 2002-02-06 Akim Demaille <akim@epita.fr>
12973 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
12974 sure not to introduce newlines in at_groups.
12975 * lib/autotest/Makefile.am (autotest.m4f): Typo.
12977 2002-02-06 Akim Demaille <akim@epita.fr>
12979 * tests/torture.at (Configuring subdirectories): Skip if aclocal
12980 is not available.
12982 2002-02-05 Paul Eggert <eggert@twinsun.com>
12984 * doc/autoconf.texi (Specific Compiler Characteristics):
12985 Describe HP-UX cc bug workaround more accurately.
12986 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
12987 not unsigned long.
12988 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
12989 cross-compilers, too. This undoes some of the most recent change
12990 to this file.
12992 2002-02-05 Akim Demaille <akim@epita.fr>
12994 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
12995 to make sure they are up to date when `check' is run.
12997 2002-02-05 Akim Demaille <akim@epita.fr>
12999 * doc/autoconf.texi (Making testsuite Scripts): Document
13000 package.m4.
13002 2002-02-05 Akim Demaille <akim@epita.fr>
13004 * lib/freeze.mk: New.
13006 2002-02-05 Akim Demaille <akim@epita.fr>
13008 Implement `autom4te --freeze'.
13010 * bin/autom4te.in (&freeze): New.
13011 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
13012 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
13014 2002-02-05 Akim Demaille <akim@epita.fr>
13016 * bin/autom4te.in (&parse_args): Implement `frozen files are
13017 optional are the sum of the previous files on the command line'.
13018 Also, pass `--reload-state=' on them, so...
13019 (handle_m4): don't.
13020 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13021 (M4sh): Rely on M4sugar.
13022 (Autotest, M4sh, M4sugar): Use frozen files.
13024 2002-01-31 Akim Demaille <akim@epita.fr>
13026 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
13027 * doc/autoconf.texi (Initializing configure): Adjust.
13029 2002-01-30 Akim Demaille <akim@epita.fr>
13031 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
13032 alphanumeric to `-' instead of `_'.
13034 2002-01-30 Akim Demaille <akim@epita.fr>
13036 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
13037 for plain code, the other for cross-compilation code. The latter
13038 is now run with GCC only.
13039 * doc/autoconf.texi (Compilers and Preprocessors): New.
13041 2002-01-30 Akim Demaille <akim@epita.fr>
13043 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
13044 values.
13045 * doc/autoconf.texi (Initializing configure): Explain how to
13046 change AC_INIT default values.
13048 2002-01-29 Akim Demaille <akim@epita.fr>
13050 * tests/torture.at (Configuring subdirectories): Use configure.in,
13051 so that aclocal 1.4 works.
13052 Reported by Alexandre Duret-Lutz and Larry Schmitt.
13054 2002-01-28 Akim Demaille <akim@epita.fr>
13056 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13057 needs an argument.
13059 2002-01-28 Akim Demaille <akim@epita.fr>
13061 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13062 AUTOTEST_PATH *after* it was set.
13063 Don't put `.' in the PATH: the user should be precise and `./' if
13064 needed. In addition, given that the test suite does some `cd', if
13065 `.' is in the path, the `tested programs' sections will report
13066 programs found in the test suite's directory, while during the
13067 tests (performed in their own directory), these programs are no
13068 longer visible. In other words, the results is confusing and
13069 useless.
13070 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
13072 2002-01-24 Akim Demaille <akim@epita.fr>
13074 Version 2.52g.
13076 2002-01-24 Akim Demaille <akim@epita.fr>
13078 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
13079 * doc/autoconf.texi: Finally add Akim as an author.
13081 2002-01-24 Akim Demaille <akim@epita.fr>
13083 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
13084 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
13085 Bourne. Use /bin/sh.
13086 From Andreas Buening.
13088 2002-01-24 Akim Demaille <akim@epita.fr>
13090 * config/config.guess, config/config.sub, config/texinfo.tex:
13091 Update from masters.
13093 2002-01-24 Akim Demaille <akim@epita.fr>

13097 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
13098 * config/missing.m4, config/sanity.m4, config/select.m4,
13099 * config/strip.m4: Remove, to ease sync'ing with any version of
13100 Automake.
13102 2002-01-24 Akim Demaille <akim@epita.fr>
13104 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
13105 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
13106 Reported by Geir Ove Myhr.
13108 2002-01-21 Akim Demaille <akim@epita.fr>
13110 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
13112 2002-01-21 Akim Demaille <akim@epita.fr>
13114 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13115 message on invalid options.
13116 * bin/autom4te.in (parse_args): Don't use
13117 Autoconf::General::getopt with non valid options.
13119 2002-01-17 Jim Meyering <meyering@lucent.com>
13121 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13122 $ac_cv_exeext so we don't use an old, invalid, cached value.
13124 2002-01-11 Akim Demaille <akim@epita.fr>
13126 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
13127 Meyering.
13128 * doc/autoconf.texi (Function Portability): Document the strnlen
13129 limitation.
13130 (Particular Functions): Document AC_FUNC_STRNLEN.

13133 2002-01-06 Akim Demaille <akim@epita.fr>
13135 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13136 package.m4, since is really depends upon configure.ac, not
13137 configure.
13138 * doc/autoconf.texi (testsuite Scripts): Adjust.
13139 * tests/Makefile.am (package.m4): New.
13140 EXTRA_DIST it since its a source.
13142 2002-01-06 Akim Demaille <akim@epita.fr>
13144 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13145 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13146 and PACKAGE_BUGREPORT from here...
13147 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13148 arguments.
13149 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13150 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13151 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13152 * tests/tools.at (autoheader): Adjust.
13153 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
13155 2002-01-06 Akim Demaille <akim@epita.fr>

13159 2002-01-03 Akim Demaille <akim@epita.fr>
13161 * doc/autoconf.texi (Output): Improved wording regarding use of
13162 AC_OUTPUT.
13163 From Olly Betts.
13165 2001-12-18 Kevin Ryde <user42@zip.com.au>
13167 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13168 sometimes needing writable input.
13170 2001-12-17 Jim Meyering <meyering@lucent.com>
13172 * doc/autoconf.texi (New Macros): Tweak wording.
13174 2001-12-14 Akim Demaille <akim@epita.fr>
13176 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13177 trailing files, don't apply `-rf' to files which might not be
13178 created by configure (core, core.*, and *.core), but just `rm -f'.
13179 Suggested by Jonathan Kamens.
13181 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13183 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13185 2001-12-14 Akim Demaille <akim@epita.fr>
13187 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13189 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13191 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13192 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13193 abs_srcdir, top_srcpath to abs_top_srcdir.
13194 (_AC_OUTPUT_FILES): Adjust.
13195 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13196 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13197 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13199 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13201 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13202 C/Fortran linking on HP/UX, by extracting the Fortran library
13203 search path from the LPATH line in the $F77 -v output.
13205 2001-12-12 Kevin Ryde <user42@zip.com.au>
13207 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13208 forbidden file descriptors table.
13210 2001-11-26 Akim Demaille <akim@epita.fr>
13212 * bin/autoscan.in (%c_keywords): Build it at top level.
13213 Map to 1 in order to simplify its uses.
13215 2001-11-26 Akim Demaille <akim@epita.fr>
13217 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13218 Remove $filepath, useless.
13219 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13220 variables, they are really part of the tokens.
13221 Split the input line on spaces and then look for tokens.
13222 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13223 because of `lex$U.$(OBJEXT)'.
13224 (&scan_files): Use "@list" instead of join.
13225 * doc/Makefile.am (CLEANFILES): Add *.fns.
13227 2001-11-26 Akim Demaille <akim@epita.fr>
13229 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13230 Remove, replaced by...
13231 * tests/wrappl.in: Be common for all the Perl executables.
13232 In particular autoscan and autoheader want -I.
13233 * configure.ac: Adjust.
13234 * lib/autoscan/headers: errno.h is portable.
13236 2001-11-26 Akim Demaille <akim@epita.fr>
13238 * bin/autoscan.in (used): New.
13239 Use it.
13241 2001-11-26 Akim Demaille <akim@epita.fr>
13243 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13244 directives.
13245 (&scan_sh_file): Remove a duplicate pattern.
13246 (&check_configure_ac): Use long options.
13247 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13249 2001-11-26 Akim Demaille <akim@epita.fr>
13251 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13252 Before, having a line containing the opening of a multi line
13253 comment made the whole line be ignored.
13255 2001-11-26 Akim Demaille <akim@epita.fr>
13257 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13258 (testsuite Scripts): Be one of its subsection.
13259 (Autotest Logs): New.
13261 2001-11-26 Akim Demaille <akim@epita.fr>
13263 Test groups are now run two directories deeper.
13265 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13266 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13267 at_top_builddir.
13268 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13269 top_srcdir, builddir and top_builddir.
13270 Use `at_*dir' relatively to the directory containing the
13271 suite, use `*dir' when relatively to the current group dir.
13273 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13275 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13276 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13277 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13278 spelling errors.
13280 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13282 * doc/autoconf.texi (Using System Type): Add an example of `case
13283 $host' usage so people quit using `case $target' everywhere.
13285 2001-11-22 Akim Demaille <akim@epita.fr>
13287 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13288 spotted by Jim Meyering.
13290 2001-11-16 Paul Eggert <eggert@twinsun.com>
13292 This patch implements a `long double' suggestion by Oliver Kiddle.
13294 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13295 static, to catch errors if the value isn't known at compile-time
13296 and the compiler supports dynamic arrays. Change its name from
13297 `_array_' to `test_array' to avoid potential name clashes.
13298 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13299 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13300 better than double. Catch a bug in GCC 2.95.2 x86.
13301 * doc/autoconf.texi (C Compiler): Document the above.
13302 * NEWS: Likewise.
13304 2001-11-13 Akim Demaille <akim@epita.fr>
13306 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13307 hand.
13308 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13310 2001-11-13 Akim Demaille <akim@epita.fr>
13312 * lib/autotest/general.m4 (AT_INIT): After having run the test
13313 group, go back to the initial directory, not to at_suite_dir.
13315 2001-11-13 Akim Demaille <akim@epita.fr>
13317 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13318 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13319 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13320 option.
13321 (AT_CHECK_CONFIGURE): Use absolute paths.
13322 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13323 The problem is still the old one: there is no means in M4 (that I
13324 know about) to create a defining macro, because there is no means
13325 to create `$1' etc., therefore, the defining macro ``swallows''
13326 all the arguments meant to the defined macro.
13328 2001-11-13 Akim Demaille <akim@epita.fr>
13330 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13331 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13332 configure.ac.
13333 * tests/aclocal.m4: Remove, as it is no longer used.
13335 2001-11-13 Akim Demaille <akim@epita.fr>
13337 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13338 variable names when referring to a single test group, or to
13339 `suite' when referring to the whole test suite.
13340 `at_last_test' is removed: m4 compute at_format itself.
13341 (at_stdout, at_stder1, at_stderr): New variables.
13342 (AT_CHECK): Use them.
13344 2001-11-13 Akim Demaille <akim@epita.fr>
13346 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13347 in PATH.
13348 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13349 Do it as soon as a test fails, don't wait till the end of the test
13350 suite.
13351 Don't remove $as_me.[0-9]*, since these files no longer exist.
13353 2001-11-13 Akim Demaille <akim@epita.fr>
13355 * tests/tools.at: Use absolute paths, since we are no longer run
13356 in place.
13358 2001-11-13 Akim Demaille <akim@epita.fr>
13360 Now that tests are running in their own private dir, there is no
13361 need to list the files to remove at the end of tests groups.
13363 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13364 (AT_data_files, at_data_files): Remove.
13365 (AT_CLEANUP, AT_DATA): Simplify.
13366 (AT_INIT): Adjust.
13367 Remove the group dir if !debug && !failed.
13368 * tests/atspecific.m4: Adjust.
13370 2001-11-13 Akim Demaille <akim@epita.fr>
13372 Start a new layout for Autotest: `testsuite' creates
13373 `testsuite.dir' in which the at-check-line etc. files are to be
13374 found, and `testsuite.dir/003' where the test group 3 is run.
13376 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13377 at_check_line_file, at_format, at_test_normalized, at_group_dir
13378 are new variables.
13379 Create the directories.
13380 Use absolute paths for at- files.
13381 (AT_CHECK): Adjust.
13383 2001-11-11 Michael Matz <matz@kde.org>
13385 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13386 (m4_car2): New.
13387 (m4_car): Properly quote arguments.
13389 2001-11-13 Akim Demaille <akim@epita.fr>
13391 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13392 with stricter rules on LIBOBJS.
13394 2001-11-12 Paul Eggert <eggert@twinsun.com>
13396 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13397 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13398 __PROTOTYPES too.
13400 2001-11-12 Akim Demaille <akim@epita.fr>
13402 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13404 2001-11-12 Akim Demaille <akim@epita.fr>
13406 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13407 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13408 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13409 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13410 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13411 specify to what the macro should be defined (typically to 1).
13413 2001-11-12 Akim Demaille <akim@epita.fr>
13415 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13416 From Jim Meyering.
13418 2001-11-12 Akim Demaille <akim@epita.fr>
13420 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13421 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13422 definition used by Automake where LEX is +/- "${missing} lex" and
13423 `missing' itself contains variables.
13425 2001-11-12 Akim Demaille <akim@epita.fr>
13427 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13428 Now that M4sh pushes BODY, the comments were output at the end of
13429 the test suites.
13431 2001-11-08 Akim Demaille <akim@epita.fr>
13433 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13434 that we can trace macros from aclocal.m4.
13435 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13436 obsoleted, and redirect to the former anyway.
13437 Reported by Ralf Corsepius.
13439 2001-11-08 Akim Demaille <akim@epita.fr>
13441 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13442 processed only if present.
13443 * tests/torture.at (Configuring subdirectories): Use autoreconf
13444 instead of successive calls to autoconf.
13445 Add a nonexistent subdirectory to exercise the patch above.
13446 Reported by Ralf Corsepius.
13448 2001-11-08 Kevin Ryde <user42@zip.com.au>
13450 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13451 doesn't accept .S files.

13459 (handle_output): Use it.
13460 Read m4_pattern_forbid with messages.
13462 2001-11-05 Akim Demaille <akim@epita.fr>
13464 * bin/autom4te.in (--normalize): Remove.
13465 * lib/autom4te.in: Adjust.
13467 2001-11-05 Akim Demaille <akim@epita.fr>
13469 * tests/Makefile.am (testsuite): Rename this target as...
13470 ($(TESTSUITE)): this.
13471 From Nicolas Joly.
13473 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13475 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13476 the --prefix option, also remove it's argument.
13478 2001-11-05 Akim Demaille <akim@epita.fr>
13480 * doc/autoconf.texi (testsuite Invocation): Update.
13481 (Writing testsuite.at): Update.

13489 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13490 (&file_name_is_absolute): New, wrappers around routines from
13491 File::Spec.
13492 Use and export them.
13493 (&find_configure_ac): Optionally take a directory where to look at.
13494 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13495 the arguments.
13496 Default @ARGV to `.', not find_configure_ac.
13497 (&autoreconf): Argument is a directory.
13498 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13499 * doc/autoconf.texi (autoreconf Invocation): Update.
13501 2001-11-03 Akim Demaille <akim@epita.fr>
13503 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13504 (@export_forward_subs): New.
13505 Add basename, dirname, and fileparse.
13506 (@EXPORT): Adjust.
13507 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13508 Don't look for aclocal flags if we already know aclocal is not
13509 used.
13510 Move aclocal.m4t only if it exists.
13511 Reported by Ezra Peisach.
13513 2001-11-03 Akim Demaille <akim@epita.fr>
13515 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13516 passed on command line, defaulting to ./configure.ac if present.
13517 (&maybe_autoreconf, File::Find): Remove, unused.
13518 (&autoreconf): If autoconf is not used, don't try to trace.
13520 2001-11-02 Akim Demaille <akim@epita.fr>
13522 * configure.ac: Bump to 2.52g.
13524 2001-11-02 Akim Demaille <akim@epita.fr>
13526 Version 2.52f.
13528 2001-11-02 Akim Demaille <akim@epita.fr>
13530 * config/config.guess, config/config.sub, doc/standards.texi:
13531 * config/lispdir.m4: Update from masters.
13532 * configure.ac: Bump to 2.52f.
13534 2001-11-02 Akim Demaille <akim@epita.fr>
13536 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13537 Don't run aclocal when aclocal.m4 is not from aclocal.
13538 From Ezra Peisach.
13539 Don't run libtoolize and gettextize if --install is not given.
13541 2001-11-01 Paul Eggert <eggert@twinsun.com>
13543 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13544 be invoked before _AS_LINENO_PREPARE.
13545 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13546 than character ranges.
13548 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13549 invoking AS_BASENAME. Set the locale variables to 'C' if
13550 possible, as POSIX requires this to get the traditional
13551 behavior.
13552 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13554 2001-10-31 Paul Eggert <eggert@twinsun.com>
13556 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13557 with {}, as that triggers a bug in Bash 2.05.
13559 (_AS_LINENO_PREPARE): Use Sed rather than
13560 Awk. Fix the sed prepass to work even if there are multiple
13561 instances of $LINENO on the same line. Do not substitute for
13562 other variables like $LINENOT. Do not check file dates; such a
13563 check is unreliable on sufficiently fast machines, and removing
13564 the check makes the code simpler and more reliable. Check for
13565 output and chmod failures.
13567 * doc/autoconf.texi (Special Shell Variables): Document
13568 the above.
13570 2001-10-31 Akim Demaille <akim@epita.fr>
13572 * tests/Makefile.am (atconfig): Remove this target, Automake
13573 handles it now.
13575 2001-10-31 Akim Demaille <akim@epita.fr>
13577 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13578 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13579 provided, while it is optional.
13580 * configure.ac: Adjust.
13582 2001-10-26 Paul Eggert <eggert@twinsun.com>
13584 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13585 lib/Autom4te/Struct.pm:
13586 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13587 with 5.005_02.
13589 * doc/autoconf.texi (Special Shell Variables): Document some
13590 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13592 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13593 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13594 eval $LINENO is not portable in practice.
13596 2001-10-24 Akim Demaille <akim@epita.fr>
13598 * lib/Autom4te/General.pm (backname): New.
13600 2001-10-24 Akim Demaille <akim@epita.fr>
13602 * m4/: Remove, merged into...
13603 * config/: here.
13605 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
13607 * doc/autoconf.texi (Shellology): Mention the problems with bash
13608 2.05's use of ANSI quoting in its `set' builtin.
13610 2001-10-22 Paul Eggert <eggert@twinsun.com>
13612 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13613 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13614 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13615 POSIX decided to standardize on the int flavor of strerror_r.
13616 Always do char* test, as there's no reason not to.
13617 Assign to a char* var, to catch strerror_r that returns int*.
13619 * doc/autoconf.texi (Particular Functions):
13620 Document the above changes. Also, document the fact that
13621 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13623 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13625 2001-10-20 Akim Demaille <akim@epita.fr>
13627 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
13628 the executable was missing from the log.

13632 * lib/Autom4te/General.pm (&update_file): If destination is
13633 unchanged, remove the source.
13634 (&up_to_date_p): Don't be verbose, be debug.
13635 * bin/autoreconf.in: No longer support --m4dir.
13636 (&autoreconf): Display the full path of the configure.ac we are
13637 studying.
13638 Trace it only once.
13639 Be sure to honor --force with gettextize.
13640 Always run aclocal.
13641 * doc/autoconf.texi: Adjust.
13643 2001-10-20 Akim Demaille <akim@epita.fr>
13645 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
13646 Remove, dead.
13647 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13648 `intl' is already present, as it refuses unless --force.
13649 (&parse_args): Use -I, --include instead of the old Autoconf
13650 options.
13651 ($localdir, $autoconf_dir): Remove.
13652 (@include): New.
13653 (&maybe_autoreconf): New, to preserve $_ for File::Find.
13655 2001-10-19 Jens Petersen <petersen@redhat.com>

13662 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
13663 file in @configure_input@.
13664 Don't mention `automatically' in addition to `generated'.
13665 * tests/torture.at (#define header templates): Adjust.
13667 2001-10-19 Akim Demaille <akim@epita.fr>
13669 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
13670 comment, explain how to install automatic mode selection.
13671 From Russ Allbery.
13673 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
13675 * bin/autoreconf.in (autoreconf): Display the path to the
13676 configure.ac being studied.
13678 2001-10-18 Paul Eggert <eggert@twinsun.com>
13680 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
13681 long, to work around a bug in the HP C compiler version HP92453-01
13682 B.11.11.23709.GP.
13684 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
13685 (AS_BASENAME_EXPR): New macro.
13686 (AS_BASENAME_SED): Do not assume GNU sed semantics.
13687 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
13688 and fall back on 'sed' only if the other two fail. This makes
13689 AS_BASENAME act more like AS_DIRNAME.
13690 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
13691 contains white space.
13692 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
13693 Use AS_DIRNAME, since I think it's now DOS-friendly.
13694 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
13695 Allow "dirname //FOO" to return either / or //, as POSIX allows
13696 either behavior.
13698 2001-10-10 Akim Demaille <akim@epita.fr>
13700 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
13701 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
13702 From Eric Sharkey.

13706 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
13707 m4_define, since...

13746 bother with $force since...

13801 2001-10-08 Akim Demaille <akim@epita.fr>
13803 Use `add-log-current-defun-function' for ChangeLog creation.
13804 Suggested by Tom Tromey.

13807 (autotest-mode): Adjust.

13823 * lib/autotest/general.m4 (AT_INIT): Likewise.
13824 * tests/base.at: Adjust the tests to use AS_INIT.
13825 * tests/tools.at (AT_DATA_FORBIDDEN): New.

13831 * doc/autoconf.texi (config.status Invocation):
13832 CONFIG_SHELL defaults to a shell that supports LINENO if available.
13834 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
13835 shell does not support LINENO, and if CONFIG_SHELL is unset or
13836 empty, and if we can find a shell that does support LINENO,
13837 then set CONFIG_SHELL to that shell and then re-execute
13838 ourselves with CONFIG_SHELL.
13840 2001-10-05 Paul Eggert <eggert@twinsun.com>
13842 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
13843 doesn't exist. Remove *.tmp, as a .tmp file is created during the
13844 build of $(TESTSUITE).
13846 2001-10-05 Akim Demaille <akim@epita.fr>

13857 Fix the absolute path case/esac pattern.
13858 Provide $0 as fallback for as_myself.

13869 (AS_SHELL_SANITIZE): here. Use it.
13870 (_AS_LINENO_PREPARE): Preserve the exit status of $0.lineno.
13871 From Paul Eggert.
13873 2001-10-04 Akim Demaille <akim@epita.fr>
13875 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable
13876 combination of Awk and sed to replace $LINENO.
13878 2001-10-02 Paul Eggert <eggert@twinsun.com>
13880 * doc/autoconf.texi (Limitations of Builtins): You can't use
13881 "source"; it's not portable. Remove confusing and
13882 somewhat-incorrect example involving "." and "/".
13884 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
13885 compatibility with POSIX shells.
13887 2001-10-02 Akim Demaille <akim@epita.fr>
13889 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
13890 instead of exec'ing to preserve $0 and $@.
13892 2001-10-01 Akim Demaille <akim@epita.fr>
13894 * tests/testsuite (AT_INIT) <at_pass_list>: New.
13895 Don't run twice the same test.

13913 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
13914 Don't use nested parenthesization. This patch was originally
13915 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
13916 but somehow it didn't get incorporated then.
13917 * doc/autoconf.texi (Limitations of Usual Tools):
13918 Clarify remark about sed and nested parenthesization.
13920 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):

13922 the type exists.
13923 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13924 Check for `expr' arithmetic overflow, and for compilation failure,
13925 and invoke a new argument $4 if either is discovered.
13926 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
13927 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
13929 2001-09-28 Akim Demaille <akim@epita.fr>

13937 * lib/autotest/general.m4 (AT_VICTIMS): Rename as...
13938 (AT_TESTED): this.
13939 (AT_INIT): More the wrapped section to where it will be expanded.
13940 Output `AT_tested' only when existing.
13941 Catch unexpanded PACKAGE_STRING and PACKAGE_BUGREPORT.
13943 2001-09-27 Akim Demaille <akim@epita.fr>
13945 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
13946 generates too many bug reports.
13948 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
13949 status when executing the ACTION-IF-FALSE.
13950 * tests/base.at (AC_TRY_*): Rename as...

13957 * tests/c.at (Extensions, C keywords)
13958 (Broken/missing compilers, AC_PROG_CPP with warnings)
13959 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
13960 (AC_PROG_CPP requires AC_PROG_CC): here and...
13961 * tests/fortran.at (GNU Fortran 77): there.
13962 * doc/autoconf.texi (autoconf Invocation): Fix the example:
13963 AC_TRY_RUN is about compilation, not shell commands.
13964 (Test Programs): AC_TRY_RUN works as used to be advertised.
13966 2001-09-27 Akim Demaille <akim@epita.fr>
13968 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
13969 Raja R Harinath:
13970 Be sure to detect when $LINENO always returns the same value.
13971 Look for the original script, basename($0) is certainly not
13972 enough.
13973 Pass the CLI arguments to `$as_me.lineno'.
13975 2001-09-25 Akim Demaille <akim@epita.fr>
13977 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

13985 of --language now.
13987 2001-09-23 Akim Demaille <akim@epita.fr>
13989 * doc/autoconf.texi (Top): Wrap in @ifnottex.
13991 2001-09-23 Akim Demaille <akim@epita.fr>
13993 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
13994 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
13995 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
13996 builddir, buildpath, top_builddir, and top_buildpath.
13997 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
13998 the current directory.
13999 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
14000 variables *before* changing the current directory.

14003 variables.
14005 * lib/autotest/general.m4: Do not reset AT_victims.
14006 Don't compute at_srcdir nor at_top_srcdir.
14008 * tests/tools.at: Hence use top_srcdir.
14010 * tests/Makefile.am, tests/autoconf, tests/autoheader,
14011 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
14012 Remove.
14013 * tests/autoreconf.in, tests/wrappl.in, tests/autom4te.in,
14014 * tests/wrapsh.in, tests/autoupdate.in: New.
14015 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
14016 * configure.ac: Build the position independent wrappers.
14018 * man/Makefile.am: Now that test wrappers are position
14019 independent, use them and drop dark envvar magic.
14021 2001-09-23 Akim Demaille <akim@epita.fr>
14023 * doc/autoconf.texi (Common Shell Constructs): Rename as...
14024 (Programming in M4sh): this.
14025 Promote to @section.

14052 (Autoconf): Adjust.
14054 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
14056 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,

14068 * tests/Makefile.am (package.m4): Remove.
14070 2001-09-22 Akim Demaille <akim@epita.fr>
14072 Rely on `$LINENO' when possible instead of `__oline__'.
14074 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
14075 `$LINENO' support replacement when not supported.
14076 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
14077 them explicitly to be sure they are not output before this section
14078 (via m4_require). Cosmetic only.
14079 * lib/autoconf/c.m4, lib/autoconf/general.m4,
14080 * lib/autoconf/programs.m4: Replace all the occurrences of
14081 `__oline__' with `$LINENO'.
14082 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
14084 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
14086 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
14087 character (u: -> ue) in a code comment.
14088 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
14089 it works.
14091 2001-09-21 Akim Demaille <akim@epita.fr>
14093 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
14094 Suggested by Jim Meyering.
14096 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14098 * lib/autoconf/programs.m4: Use extensions listed in
14099 $ac_executable_extensions when looking for programs.
14101 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14103 * lib/autoconf/general.m4: Fix a small Englisho.
14104 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
14105 setting up ac_dir_suffix and ac_top_builddir.
14106 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
14108 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14110 * doc/autoconf.texi (File System Conventions): Clarify the use of
14111 PATH_SEPARATOR.
14112 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
14113 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
14114 be used instead of ':'.
14115 * lib/autotest/general.m4: Replace occurrences of ':' in
14116 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14118 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14120 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14121 arguments. Fixed a typo.
14123 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14125 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14126 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14128 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14130 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
14131 * bin/autoupdate.in: Ditto.
14132 * bin/autoheader.in: Reworded a few comments.
14133 * bin/autoconf.in: Reworded help text for a few options.
14134 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
14135 * bin/autoscan.in, bin/autoupdate.in: Ditto.
14137 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14139 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14140 already have $file). Set output files to binary mode (helps avoid
14141 CR issues on DOSish systems).
14143 2001-09-19 Akim Demaille <akim@epita.fr>
14145 * lib/autotest/general.m4: Englishoes.
14146 From Tim Van Holder and Alexey Mahotkin.
14148 2001-09-18 Paul Eggert <eggert@twinsun.com>
14150 * doc/autoconf.texi (Common Shell Constructs): New node,
14151 documenting AS_DIRNAME.
14152 (Limitations of Usual Tools): Refer to it when discussing dirname.
14153 Also, update discussion of POSIX standard to reflect latest draft.
14155 * lib/autoconf/c.m4:
14156 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14158 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14159 Do not pass a first argument with leading '-'
14160 to expr, by parenthesizing initial integers that might be negative.
14162 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14163 now merely checks whether it is an error to pass an argument
14164 to getpgrp.
14166 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14167 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14168 whether it is a (compile-time) error to pass an argument to
14169 getpgrp. This simpler test supports the revised documentation,
14170 and is all that AC_FUNC_GETPGRP's users really need.
14172 2001-09-18 Akim Demaille <akim@epita.fr>
14174 * doc/autoconf.texi (Limitations of Make) <$<>: New.
14176 2001-09-18 Akim Demaille <akim@epita.fr>

14179 `{}'.
14180 * lib/autotest/general.m4 (AT_INIT): Adjust.
14182 2001-09-18 Paul Wagland <paul@wagland.net>
14184 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14185 correctly.
14186 Add test for AS_BASENAME.
14187 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14188 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14189 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14190 * tests/base.at: Fixed the expected responses. The old ones were
14191 one line out...
14192 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14193 the documentation claims it should (and how it behaved in 2.13).
14195 2001-09-18 Akim Demaille <akim@epita.fr>
14197 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14198 the AC_CONFIG_COMMANDS invocation.
14199 This also solves the name clash problems.
14200 Don't set the package's ID.
14201 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14202 No longer to be shipped.
14203 (version.in): Remove.
14204 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14205 * lib/autoconf/status.m4: Adjust.
14206 Use `m4_PACKAGE_STRING'.
14207 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14208 the only optional argument is the name of the test suite.
14209 Expect `package.m4' to define the package signature.
14210 * lib/autom4te.in (Autotest): Add `package.m4?'.
14211 * tests/Makefile.am (package.m4): New.
14212 * tests/suite.at: ifnames is a victim.
14214 2001-09-18 Akim Demaille <akim@epita.fr>
14216 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14217 AC_LIBSOURCE, AC_CONFIG_FILES.
14218 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14219 program version string doesn't match the package's.
14220 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14221 after `(cached)'.
14223 2001-09-17 Paul Eggert <eggert@twinsun.com>
14225 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14226 Allow expression to return any value that can fit into unsigned long
14227 (not int, as before). Check for output errors.
14229 2001-09-17 Bruno Haible <haible@ilog.fr>
14231 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14232 Always include <stdio.h> and <stdlib.h>. Evaluate
14233 the expression in an extra function before these includes. Call
14234 fprintf "%d" only after ensuring the argument is of type 'int'.
14235 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14237 2001-09-17 Paul Eggert <eggert@twinsun.com>
14239 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14240 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14241 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14242 when they don't exist.
14244 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14245 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14246 need it.
14248 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14249 version with the version used by fileutils 4.1, except use
14250 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14251 we don't need it.
14253 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14255 2001-09-13 Akim Demaille <akim@epita.fr>
14257 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
14258 _first_.
14259 Reported by Gerrit P. Haase.
14261 2001-09-13 Akim Demaille <akim@epita.fr>
14263 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
14264 m4_defn'ing is valid.
14266 2001-09-13 Akim Demaille <akim@epita.fr>
14268 * lib/m4sugar/m4sugar.m4 (m4_append_uniq): New.
14269 * lib/autotest/general.m4 (AT_VICTIMS, AT_KEYWORDS, _AT_CLEANUP_FILE):
14270 Use it.
14272 2001-09-13 Akim Demaille <akim@epita.fr>
14274 * lib/m4sugar/m4sugar.m4 (_AS_QUOTE_IFELSE, _AS_BOX_INDIR): Use
14275 m4_match.
14276 (m4_re_escape): New.
14277 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER): Use it.
14278 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
14279 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
14280 Likewise.
14281 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
14282 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
14283 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
14284 AT_tests_all for consistency.
14285 Set at_victims.
14286 (AT_VICTIMS): Similar to AT_KEYWORDS.
14287 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
14289 2001-09-13 Akim Demaille <akim@epita.fr>
14291 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
14293 2001-09-13 Akim Demaille <akim@epita.fr>
14295 * lib/autotest/general.m4 (AT_INIT): Create and remove
14296 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14297 test suites can cohabit.

14407 2001-09-05 Akim Demaille <akim@epita.fr>
14409 Be ready to handle filenames as stupid as `dnl.at', for if even
14410 the maintainer is dumb enough to do that...
14412 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14413 excellence in M4 quotation: consider `__file__' is active.
14415 And BTW, when invoking m4, pass the --include in the right order:
14416 the wrong one.
14418 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
14419 4m.

14443 CVS GNU M4 doesn't like `undefine(undefined)'.
14445 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
14446 New, extracted from main.
14447 Use IO::File wherever possible.
14448 (input.m4): Be constant, use -I instead of hard coding $tmp.
14449 Therefore be a quoted heredoc.
14450 Don't invoke `_au_disable', since ac was not loaded, but just
14451 `unm4.m4'.
14453 2001-08-31 Akim Demaille <akim@epita.fr>
14455 Version 2.52d.

14478 2001-08-31 Akim Demaille <akim@epita.fr>
14480 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
14481 (testsuite Scripts): There is no such thing as `atconfig.in'.
14482 And actually one diagram is missing: test suite runtime.
14484 2001-08-31 Akim Demaille <akim@epita.fr>
14486 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
14487 inverse order.
14489 2001-08-31 Akim Demaille <akim@epita.fr>
14491 * bin/autoupdate.in (@include): `installcheck' revealed the path
14492 to m4sugar was lacking!
14494 2001-08-31 Akim Demaille <akim@epita.fr>
14496 * man/Makefile.am (.x.1): We really have to pass
14497 autom4te_perllibdir.
14499 2001-08-31 Akim Demaille <akim@epita.fr>
14501 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
14502 debug scripts, in particular passing explicitly listed tests to
14503 run is stupid.
14505 2001-08-31 Akim Demaille <akim@epita.fr>
14507 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
14508 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
14509 Use directly autom4te, not autoconf.
14510 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
14512 2001-08-31 Akim Demaille <akim@epita.fr>
14514 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

14524 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
14525 need for autoconf.
14526 Promote --include over --macrodir and other obsolete options.
14528 2001-08-31 Akim Demaille <akim@epita.fr>
14530 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

14532 * bin/autom4te.in ($autoconf): Pass --force.
14533 `print $out' doesn't print `$_' but `$out'.
14534 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
14535 (autoheader): Pass --force since the test suite goes too fast for
14536 the time stamps.
14537 Adjust to the new autoheader messages.
14539 2001-08-31 Akim Demaille <akim@epita.fr>
14541 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
14542 Check the completeness of the #template.

14551 Drop AC_MACRODIR dead for real.
14552 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
14553 `autoheader: `config.hin' is created'.
14554 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
14556 2001-08-31 Akim Demaille <akim@epita.fr>
14558 * bin/autoheader.in: Rewrite in Perl.
14559 * tests/autoheader: Adjust.
14561 2001-08-31 Akim Demaille <akim@epita.fr>
14563 * bin/autoconf.in (--include, -I): New option.
14564 Map --localdir, --autoconf-dir onto it.
14565 Forward autom4te's options instead of interpreting them.
14566 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
14567 There is no such envvar since the inception of autom4te.cfg.
14568 * bin/autom4te.in (&parse_args): Uniquify `@include'.
14569 * bin/autoupdate.in: Adjust, and perform more control.

14573 2001-08-31 Akim Demaille <akim@epita.fr>
14575 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
14576 * bin/autom4te.in (&find_file): Support `FILE?' standing for
14577 optionally `FILE'.
14578 Use -e, not -f, since /dev/null for instance is OK.
14579 (&parse_args): Adjust.
14580 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
14582 2001-08-31 Akim Demaille <akim@epita.fr>
14584 * configure.ac: Also find tested executables in bin.
14585 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
14586 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
14587 installed peer executables, only PATH is allowed to resolve it.
14588 Pass `autoconf_dir' via options, not via invisible envvars.
14589 * lib/Autom4te/General.pm (&find_peer): Remove.
14590 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
14591 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
14592 * man/Makefile.am: Let help2man rely on PATH instead of trying to
14593 find the executables for it.
14594 * tests/Makefile.am: Major cleanup. Too lazy to document...
14595 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14596 We only need PERL.
14597 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14598 indeed related to running the test suite, while passing
14599 --autoconf-dir and others is related to running non installed
14600 Autoconf executables. So don't do that, leave it to...
14601 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
14602 * tests/autoscan: New.
14603 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
14604 refer to library files: rely on --language.
14606 2001-08-29 Akim Demaille <akim@epita.fr>
14608 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

14611 2001-08-29 Akim Demaille <akim@epita.fr>
14613 * doc/autoconf.texi: Strip the @nodes.
14614 Suggested by Paul Eggert.

14617 2001-08-29 Akim Demaille <akim@epita.fr>
14619 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
14620 Suggested by Paul Eggert.
14622 2001-08-29 Akim Demaille <akim@epita.fr>
14624 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
14625 download in a tmp dir.
14627 2001-08-29 Akim Demaille <akim@epita.fr>
14629 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

14641 * bin/autoconf.in: Simplify and adjust.
14642 * tests/Makefile.am (AUTOMAKE): Use --set.
14643 * tests/atlocal.in: Adjust.
14644 * BUGS: distcheck and check are weak.
14646 2001-08-29 Akim Demaille <akim@epita.fr>
14648 * lib/autotest/general.m4: Use
14649 foo=`(command) 2>/dev/null`
14650 not
14651 foo=`command` 2>/dev/null
14652 (at-devnull): Rename as...
14653 (AT-devnull): this.
14654 (--clean): Remove AT-* files too.
14655 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
14656 Reported by Nicolas Joly.

14690 * lib/autotest/general.m4 (AT_INIT): Log the command line.
14691 Support `VAR=VAL' as arguments.

14711 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
14712 `ac_top_builddir' to mimic Automake's vocabulary, which much more
14713 readable.
14714 Adjust callers.
14715 * doc/autoconf.texi (Configuration Actions): Document the vars
14716 available in commands.
14717 Emphasize the risks of collisions in init-cmds.

15199 2001-08-07 Akim Demaille <akim@epita.fr>
15201 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15202 removed.
15203 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15204 No need to remove the files before and after the each test, before
15205 each test and at the end of the suite is enough.
15206 Display only the children `times', not the shell's.
15207 If the test failed or was skipped, at-times is not available.
15209 2001-08-07 Akim Demaille <akim@epita.fr>
15211 Always produce testsuite.log, including when there are no
15212 failures. This helps getting information on skipped tests, and
15213 duration of the tests. Err, implement the latter btw.
15215 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15216 Dump information on the first run of each test.
15217 (AT_CLEANUP): Create `at-times' containing the duration of the
15218 test group.
15220 2001-08-07 Akim Demaille <akim@epita.fr>
15222 The use of `dumpstat' revealed that `len' was used although it
15223 should not. m4_text_wrap was using it, but in the Autoconf world
15224 where it is legal. Hence (i) test M4sh in its own world, not
15225 Autoconf's, and (ii), ahem, fix the bug :)
15227 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15228 does not like `' instead of [].
15229 (AT_INIT): Forbid `^_?AT_'.
15230 And don't output such tokens.
15231 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15232 `script.as', and `autom4te.cache'.
15233 Remove `empty' and `macro' which are no longer used.
15234 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15235 * tests/m4sugar.at: Use it.
15236 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15238 2001-08-07 Akim Demaille <akim@epita.fr>
15240 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.

15244 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15246 2001-08-04 Akim Demaille <akim@epita.fr>
15248 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15249 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15250 AC_TRY_LINK.
15251 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15252 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15253 (AC_F77_MAIN): Likewise.
15255 2001-08-04 Akim Demaille <akim@epita.fr>
15257 Don't rely on M4sugar outputting the patterns in files, since we
15258 might process the output _without_ running m4, hence without these
15259 files.
15261 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15262 * bin/autom4te.in (@Request::includes): Remove, unused.
15263 (@Request::source): Rename as...
15264 (@Request::input): this.
15265 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15266 (&handle_output): Fetch the patterns from the traces.
15267 `$forbidden' and `$allowed' are constant: use m//o.
15268 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15269 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15271 2001-08-04 Akim Demaille <akim@epita.fr>
15273 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15274 autoconf', i.e., in addition to caching traces, cache the output.
15276 * bin/autom4te.in (Request::cache): Rename as...
15277 (Request::id): this.
15278 ($cache, $icache, $tcache, $ocache): New.
15279 (&handle_m4): Save M4 output in the cache instead of $tmp.

15282 (top level): Run `&handle_m4' iff force or the cache is invalid.
15283 Run `&handle_output' if the output cache is more recent.
15285 2001-08-04 Akim Demaille <akim@epita.fr>
15287 * bin/autom4te.in ($force): New.
15288 (&parse_args, &print_usage): -f, --force is a new option.
15289 (&handle_output): CPP directives might have spaces after `#'.
15290 (&parse_args): The first file only can be frozen.
15292 2001-08-04 Akim Demaille <akim@epita.fr>
15294 Don't let autom4te compute the `include' traces several times:
15295 first check that the trace cache file is up to date, and then
15296 compare its timestamp with that of the output.
15298 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15299 the preamble. Don't require 5.005 as Autom4te::General does it,
15300 and better yet (use `use', not `require'!).
15301 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15302 Class::Struct as Autom4te::Struct.
15303 * lib/Autom4te/General.pm (File::stat): Use it.
15304 (&mtime): New, export it.
15305 * bin/autom4te.in: Use it.
15306 Declare `$req' is invalid if it is outdated.
15307 Don't declare it valid before saving it if something went wrong.
15309 2001-08-04 Akim Demaille <akim@epita.fr>
15311 Autom4te shall not encode Autoconf data, and preselecting traces
15312 must be proposed to the users.
15314 * bin/autom4te.in (@required_trace): Remove.
15315 (@preselect): New.
15316 (&parse_args, &print_usage): -p, --preselect is a new option.

15318 * bin/autoconf.in: Preselect some Autoconf macros.
15320 2001-08-04 Akim Demaille <akim@epita.fr>
15322 * tests/tools.at (autoconf --trace: user macros): Check traces on
15323 macros invoked without arguments, and macros invoked with multiple
15324 lines arguments.
15326 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
15328 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
15329 arguments.
15331 2001-08-03 Akim Demaille <akim@epita.fr>
15333 * bin/autoconf.in ($@): Work around the usual sh bug.
15334 From Nicolas Joly.
15336 2001-08-03 Akim Demaille <akim@epita.fr>
15338 Clean up the handling of the M4 builtins tracing exception.
15340 * bin/autom4te.in (Request::request): Don't complete M4 builtins
15341 trace requests.

15343 (@m4_builtin): this.
15344 (%m4_builtin_alternate_name): New.

15356 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
15357 (m4_divert_pop): Dump the whole diversion stack when a diversion
15358 mismatch happens.
15359 * bin/autom4te.in (&handle_output): Remember of the first
15360 occurrence of a possibly undefined macro, not the last.
15361 Complain about the possibly undefined macros in the same order as
15362 the appear in the output.
15363 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
15364 * tests/tools.at (autoconf: forbidden tokens, basic)

15366 autoconf's stderr, as it is now deterministic.
15367 Check that `dnl' is caught.
15369 2001-08-01 Akim Demaille <akim@epita.fr>
15371 * configure.ac: Bump to 2.52c.

15703 For some AWK, such as on HPUX 11, `xfoo' does not match `foo|^bar'.
15704 Reported by Michael Elizabeth Chastain.
15706 * autoconf.in: Refuse such AWK.
15707 * configure.in: Likewise.
15708 * Makefile.am (acversion.m4): Do not use move-if-change this file

15786 the right thing.
15787 * Makefile.am (.m4.m4f): Emphasize M4 error messages and fail
15788 earlier if there are.
15790 2001-07-03 Akim Demaille <akim@epita.fr>

15819 * aclang.m4 (AC_F77_DUMMY_MAIN): New macro to detect whether a
15820 dummy alternate main is required even if the user provides her own
15821 'main'.
15822 (AC_F77_MAIN): New macro to detect whether it is possible to
15823 provide an alternate 'main' function name, using the 'main' from
15824 the Fortran libraries.
15825 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
15826 cross-language link tests can be performed successfully.
15827 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
15828 after $LIBS, for consistency; this should be the general rule since
15829 the user may want to link to Fortran libraries that require $FLIBS.
15830 * doc/autoconf.texi: Document AC_F77_DUMMY_MAIN and AC_F77_MAIN.
15832 2001-06-29 Pavel Roskin <proski@gnu.org>
15834 * atgeneral.m4 (AT_CHECK): Add a newline to the end of
15835 at-stdout and at-stderr instead of removing the newline
15836 from the echo output, which is not guaranteed to work.
15838 2001-06-28 Jens Petersen <petersen@redhat.com>
15840 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to

15868 2001-06-25 Akim Demaille <akim@epita.fr>
15870 * autoscan.in (%macro): Now maps from word to list of macros.
15871 (&init_tables): Die when a word which is already handled by
15872 explicit macros is mapped to the default macro.
15873 (&print_unique): Remove, inlined in...
15874 (&output_kind): here.
15875 (File::Basename): Use it.

15906 2001-06-23 Akim Demaille <akim@epita.fr>
15908 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): Consider
