1240 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
1241 for a.* when searching for executables, as this prevents users

1258 must not be anonymous.
1259 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
1260 for C++; this drops support for anonymous struct and union types,
1261 which were problematic anyway.
1262 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even

1280 with objects too. Document the restrictions on its use.
1281 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
1282 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
1283 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
1284 works but the latter doesn't, then it's a valid type.
1285 This lets people use function types and so forth.
1286 For C++ there doesn't seem to be a simple solution, so leave it alone.
1287 (AC_CHECK_SIZEOF): Allow argument to be a variable.
1288 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
1289 AC_CHECK_TYPE; that wasn't documented or necessary.

1341 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
1342 nonstandard grep R.E. escape sequences.

1350 2007-03-09 Stepan Kasal <kasal@ucw.cz>
1352 * doc/autoconf.texi (Specifying Names): `--host' does not

1460 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its

1466 $PATH_SEPARATOR is for the build system only.
1467 Report by Keith Marshall.
1469 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1471 * doc/autoconf.texi (Setting Output Variables): Mention that
1472 all non-NUL characters are ok in substituted values.
1473 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
1474 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
1475 carriage return for $AWK, needed for BSD awk.
1476 * tests/torture.at (Substitute and define special characters):
1477 Test all 8 bit non-NUL characters.
1478 Report against Automake by Patrick Welche.
1480 2007-01-15 Stepan Kasal <kasal@ucw.cz>
1482 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
1484 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1486 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
1487 early on the reader side, drop stderr of the input to avoid
1488 `broken pipe' error output; this may happen even with shell
1489 builtin `echo' of some bash versions. Reports by Ian Macdonald
1490 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
1492 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1494 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
1495 separate items of `ac_user_opts', to avoid long lines.
1496 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
1498 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1500 * doc/autoconf.texi: Fix some typos.
1502 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
1504 Fix some wording problems noted by Paolo Bonzini in:
1505 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
1506 * doc/autoconf.texi (Signed Overflow Examples): Give more
1507 discussion about the allow_superuser_privileges example,
1508 and change it a bit to make things clearer.
1509 (Optimization and Wraparound): Clarify whether the compiler
1510 will generate an infinite loop for the example derived from
1511 Autoconf's mktime test.
1512 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
1513 Also, clarify unsigned multiplication overflow.
1515 2007-01-04 Eric Blake <ebb9@byu.net>
1517 * bin/Makefile.am (RELEASE_YEAR): New macro.
1518 (edit): Use it to supply correct copyright year to scripts.
1519 * bin/autoconf.as (version): Use it.
1520 * bin/autoheader.in ($version): Likewise.
1521 * bin/autom4te.in ($version): Likewise.
1522 * bin/autoreconf.in ($version): Likewise.
1523 * bin/autoscan.in ($version): Likewise.
1524 * bin/autoupdate.in ($version): Likewise.
1525 * bin/ifnames.in ($version): Likewise.
1527 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
1529 * doc/autoconf.texi (Integer Overflow): Revised based on today's
1530 feedback. The most important changes document what happens when
1531 you convert an out-of-range value to a signed integer type, and
1532 say that (sum < a) != (b < 0) reliably detects overflow when sum =
1533 a + b.
1535 * doc/autoconf.texi (Integer Overflow): Greatly expand and
1536 rewrite, taking notions from the recent discussion on the gcc and
1537 autoconf mailing lists; please see
1538 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
1539 and follow the many links.
1540 (Integer Overflow Basics, Signed Overflow Examples):
1541 (Optimization and Wraparound, Signed Overflow Advice):
1542 (Signed Integer Division): New sections.
1544 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
1546 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
1547 preprocessor macro arguments in traced name.
1548 * doc/autoconf.texi (Defining symbols): Document longstanding
1549 support for AC_DEFINE-ing macros with arguments, and document
1550 behavior when the same variable has multiple AC_DEFINEs.
1551 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
1552 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
1553 macros directly, giving much shorter and simpler code.
1555 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
1557 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
1558 space before "$ac_configure_args" to prevent a 'config.status
1559 --recheck' failure if ac_configure_args doesn't contain a leading
1560 space. This works around a problem with the XEmacs configure.ac,
1561 which uses the (undocumented) ac_configure_args variable
1562 inconsistently with Autoconf.
1564 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
1566 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
1567 Include <limits.h>, and use its INT_MAX to rewrite the
1568 j loop so that it does not overflow 'int'. Problem reported by
1569 Ralf Wildenhues in
1570 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
1571 Play it safe by shifting left by 1 rather than multiplying by 2,
1572 as GCC is less likely to optimize this away when the value
1573 is signed (when it assumes overflow leads to undefined behavior).
1574 Also, don't assume time_t uses two's complement.
1576 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1578 * tests/torture.at (Substitute a 2000-byte string): Avoid using
1579 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
1580 dumps core on it. Report by Tim Rice.
1582 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1584 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
1585 --disable-option-checking to --help output even when
1586 AC_PRESERVE_HELP_ORDER is not used.
1587 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
1588 --with argument, rather than argument with [-.] replaced by
1589 underscores.
1590 * NEWS: Fix typo in previous change; the news was in the
1591 wrong section.
1593 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
1595 * NEWS: Warnings are now generated by default for unknown
1596 --enable-* and --with-* options.
1597 * doc/autoconf.texi (Option Checking): Renamed from
1598 (Configure Option Checking). Tighten up the wording a bit.
1599 (External Software, Package Options): Cross-reference to Option
1600 Checking, and use this to shorten our section.
1601 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
1602 "$x" to test "x$foo" != x.
1603 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
1604 Don't warn if $enable_option_checking is "no".
1605 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
1606 ac_unrecognized_opts to the empty string.
1607 Don't echo the unrecognized opts, as this might mishandle
1608 backslashes or leading -.
1609 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
1610 usage next to the other --disable-FEATURE options in the
1611 help string.
1613 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1615 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
1616 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
1617 Print warning for unrecognized --with and --enable options
1618 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
1619 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
1620 Disable option checking when subdirs are configured.
1621 (AC_OUTPUT): If warnings are enabled, print warning about
1622 unrecognized --with and --enable options at the end of
1623 the configure output (as well as at the beginning).
1624 * doc/autoconf.texi (Option Checking): New node.
1625 Document new option warning functionality.
1627 2006-12-16 Eric Blake <ebb9@byu.net>
1629 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
1630 * NEWS: Start news for current version.
1632 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
1634 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1635 Define HAVE_GETMNTENT to 1, not to the empty string.
1636 Problem originally reported by Jochen Friedrich in
1637 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
1639 This change prompted by a problem report by Andrey Simonenko in
1640 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
1641 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
1642 object-like macros only, in the traditional portable character
1643 set.
1644 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
1645 Warn about attempts to define things that are not identifiers.
1646 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
1647 awful hack that AC_DEFINEd macro names containing parentheses.
1649 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
1651 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
1652 too drastic, even if Texinfo in theory requires it for info mode.
1654 (config.status Invocation): Renamed back from Recreating a
1655 Configuration).
1656 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
1657 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
1659 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1661 * NEWS: Version 2.61a.
1663 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1664 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1666 * NEWS: Document changes with echo and printf, and the lack
1667 of limits on the total size of multi-line values of substituted
1668 variables, and the AC_FUNC_FSEEKO fix.
1670 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
1672 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
1673 Writing configure.ac.
1674 (Autoconf Input Layout): Renamed from configure.ac Layout.
1675 (Recreating a Configuration): Renamed from config.status Invocation.
1676 (Obsolete Recreation): Renamed from Obsolete config.status Use.
1677 (acconfig Header): Renamed from acconfig.h.
1678 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
1679 (Writing Testsuites): Renamed from Writing testsuite.at.
1680 (Autom4te Cache): Renamed from autom4te.cache.
1682 * BUGS: Remove mention of VPATH problem, since it's now documented
1683 not to be a bug in the Autoconf build procedure itself, but rather
1684 a problem with the proprietary `make' programs.
1686 * doc/autoconf.texi (Build Directories): Add a cross reference
1687 to VPATH and Make.
1689 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
1690 * doc/standards.texi: Sync from gnulib.
1692 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
1693 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
1694 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
1695 generated automatically.
1697 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
1699 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
1700 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
1701 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
1703 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1705 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
1706 `CEOF$ac_eof' special marker, the awk script cannot contain a
1707 line matching `^CEOF', so this is not needed any more.
1708 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
1709 special marker in the test.
1711 2006-12-06 Stepan Kasal <kasal@ucw.cz>
1713 * tests/tools.at (autom4te preselections): Use `find -newer';
1714 remove one of the sleeps.
1716 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
1717 more readable, using ...
1718 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
1720 * doc/autoconf.texi (autoheader Invocation): Do not double-
1721 quote the parameter of `AH_BOTTOM' in the example.
1723 2006-12-05 Stepan Kasal <kasal@ucw.cz>
1725 * doc/autoconf.texi (Configuration Headers): Remove the
1726 example with multiple input files.
1727 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
1728 multiple input files.
1730 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1732 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
1733 creating the awk substitution script, handle one input line at a
1734 time, so that the maximum length of a substituted (multi-line)
1735 value is not limited by the size of the sed pattern space.
1736 The trade-off is a slightly repetitive sed script.
1737 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
1738 can only have up to 7 characters, due to Solaris 10 /bin/sed.
1739 * tests/torture.at (Substitute a 2000-byte string): Increase the
1740 test with several long lines, they should not be caught by sed
1741 limits any more.
1743 * tests/tools.at (autom4te preselections): New test, to flag
1744 entries missing from autom4te.cfg.
1745 Report by David Byron <dbyron@hheld.com>.
1747 * tests/torture.at (Substitute a 2000-byte string): Actually use
1748 AC_PROG_AWK, so the last change works as intended.
1749 (Substitute and define special characters): Likewise.
1750 (Substitute a newline): Likewise.
1752 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
1753 instead of `awk' consistently.
1754 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
1755 * tests/torture.at (Torturing config.status): Test both the
1756 result of AC_PROG_AWK and plain awk.
1757 (Substitute a 2000-byte string): Likewise.
1758 (Substitute and define special characters): Likewise.
1759 (Substitute a newline): Likewise.
1761 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
1763 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
1764 can be assigned to a function pointer. Problem reported by
1765 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
1766 part of a patch by Ralf Wildenhues in that same bug report.
1768 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
1770 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
1771 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
1773 2006-12-01 Eric Blake <ebb9@byu.net>
1775 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
1776 cross-compiling from cygwin to mingw.
1777 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
1778 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
1779 to lib/autoconf/c.m4.
1781 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1783 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
1784 string for more reliable failure. Wrap the entire test that
1785 causes the broken Solaris printf to dump core, in a subshell,
1786 so the segmentation fault message is reliably suppressed.
1787 Fix shell expansion errors by using /usr/ucb/echo always;
1788 avoid an error on systems without it by another subshell.
1789 Avoid m4 expansion of `$1'. Set the zeroth argument of the
1790 subshell-$as_echo to `as_echo', for better error message.
1792 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1794 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
1795 `BASH_SOURCE' contain a newline, set them to empty, as they may
1796 not be unset.
1798 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
1800 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
1801 years and is too hard to maintain now. The last straw was
1802 reported by Jerker Baeck in
1803 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
1804 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
1805 * doc/autoconf.texi (Particular Functions): Move
1806 AC_FUNC_SETVBUF_REVERSED from here...
1807 (Obsolete Macros): ... to here. Say that it does nothing now.
1808 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
1809 Turn into (almost) a no-op.
1811 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
1812 (AC_C_VOLATILE):
1813 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
1814 These macros are obsolescent and new applications shouldn't need them.
1815 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
1816 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
1817 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
1818 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
1819 (AC_FUNC_VPRINTF): Likewise.
1820 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
1821 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
1822 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
1824 * doc/autoconf.texi (Setting Output Variables): Mention that
1825 @VAR1@VAR2 has unspecified behavior. Problem reported by
1826 Ralf Wildenhues.
1827 * NEWS: Mention this.
1829 * Makefile.am: Put only a single '#' into the copyright notice,
1830 so that it's also present in the output file. Standardize wording
1831 in makefile copyright notices to match GNU coding standards.
1832 * bin/Makefile.am: Likewise.
1833 * doc/Makefile.am: Likewise.
1834 * lib/Makefile.am: Likewise.
1835 * lib/freeze.mk: Likewise.
1836 * lib/autoconf/Makefile.am: Likewise.
1837 * lib/autoscan/Makefile.am: Likewise.
1838 * lib/autotest/Makefile.am: Likewise.
1839 * lib/m4sugar/Makefile.am: Likewise.
1840 * man/Makefile.am: Likewise.
1841 * tests/Makefile.am: Likewise.
1842 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
1843 one-line file.
1845 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1847 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
1848 in the sed script that mangles the awk script: delete up to the
1849 first exclamation mark only.
1850 * tests/torture.at (Substitute and define special characters):
1851 Test '!' too.
1853 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1855 Rewrite config files generation: avoid quadratic growth in
1856 the number of substituted variables by using awk instead of sed
1857 for the bulk of the substitutions.
1858 * NEWS: Mention this.
1859 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
1860 forbidden in the output (and thus input) file.
1861 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
1862 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
1863 generate just one large awk script for substitutions,
1864 eliminating much of the earlier complexity, while adding some
1865 new complexity. Only expand the substitution templates at
1866 configure time, for smaller configure script size. If
1867 _AC_SUBST_FILES are used, test 'awk' for working getline support
1868 at config.status time. If absent, interpolate through the
1869 shell. The awk script was written with much help
1870 from Paolo Bonzini and Paul Eggert.
1871 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
1872 (_AC_SED_FRAG_NUM): Likewise.
1873 (_AC_SUBST_CMDS): Renamed from...
1874 (_AC_SED_CMDS): ...this.
1875 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
1876 * tests/torture.at (Substitute a 2000-byte string): Also
1877 substitute a line with 1000 words, and a variable with several
1878 long lines.
1879 (Substitute and define special characters): Test awk special
1880 characters, and put substitution input strings `@foo@' in the
1881 output, to test that no recursion happens; test several other
1882 combinations from Paolo Bonzini.
1884 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
1886 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
1887 that replaced echo with AS_ECHO where this wasn't necessary.
1888 Problem reportd by Ralf Wildenhues.
1889 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
1890 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
1891 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
1893 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1895 * lib/freeze.mk (GREP): Removed, no need to initialize this.
1897 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
1899 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
1900 that traditional Awk lacks 3-arg "split". It has it.
1901 Mention that FS must be a single character, and a few other
1902 99-byte limits of traditional Awk.
1903 Mention that if (i in a) doesn't work with traditional Awk.
1905 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
1907 * tests/autotest.at (BSx641-newline in command):
1908 (BS-BS-newline in command, BSx640-newline in command):
1909 (Newline-CODE-BS-newline in command):
1910 (Single-quote-BS-newline in command):
1911 (Single-quote-newline-BS-newline in command):
1912 Use printf '%s\n' instead of echo, for portability to hosts
1913 where echo interprets backslashes. This will break on hosts
1914 that lack printf, but for now let's assume all such hosts
1915 are dead (if not, we should get reports of test failures).
1917 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
1919 'echo' has some portability problems, when given a first argument
1920 with a leading '-', or when given any argument containing '\'.
1921 Avoid using 'echo' in these cases.

1950 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):

1967 Don't set as_nl, since _AS_ECHO_PREPARE does that now.

2109 ./micro-suite -l and the title in micro-suite.log.
2110 (Backquote in a test title,
2111 Single-quote in a test title,
2112 Double-quote in a test title): Don't expect failure anymore.
2113 (Backslash in a test title): Put a non-whitespace character after the
2114 backslash so that Bourne shells might actually see it as an escape
2115 sequence.
2116 (Brackets in a test title,
2117 Pound in a test title,
2118 Comma in a test title,
2119 Quoted Macro in a test title,

2126 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
2127 The visible effect was a stray [] in the testsuite output.
2129 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2131 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
2132 `trap ... 0' inside a function, for AIX sh.
2134 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
2136 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
2137 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
2138 5363) simply issues a warning when dividing by zero at compile
2139 time. Problem reported by Elias Pipping.
2141 2006-10-26 Eric Blake <ebb9@byu.net>
2143 * THANKS: Update.
2144 * doc/autoconf.texi (Evaluation Macros): Improve the example to
2145 show effect on macros that expand with commas.
2146 Reported by Joel E. Denny.
2148 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):

2173 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
2174 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
2175 reported by Nelson H. F. Beebe for Coreutils 6.4.
2177 * tests/tools.at (autoconf --trace: user macros): Remove test
2178 for tracing multiline macros, since m4 1.4.7a uses a different
2179 way to number lines. Problem reported by Ralf Wildenhues.
2181 2006-10-24 Stepan Kasal <kasal@ucw.cz>
2183 * bin/autom4te.in (handle_m4): Do not redirect stdin to
2184 /dev/null since the heuristics for interactive behaviour was
2185 fixed in CVS m4.
2187 * bin/autom4te.in: With --force, always refresh the output
2188 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
2190 * bin/autoconf.as: Fix the verbose message at the end.
2192 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

2209 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
2210 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
2212 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2241 looking for special shell characters.
2242 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
2243 macro defined by AS_VAR_PUSHDEF before passing it as a
2244 parameter.

2255 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
2257 (Imported from Automake.)
2258 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
2259 which incorrectly sets the mode of an existing destination
2260 directory. In some cases the unpatched install-sh could do the
2261 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
2262 system. We hope this is rare in practice, but it's clearly worth
2263 fixing. Problem reported by Alex Unleashed in
2264 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
2265 Also, don't bother to check for -m bugs unless we're using -m;
2266 suggested by Stepan Kasal.

2303 * build-aux/texinfo.tex (\textdegree): New command.
2305 2006-08-12 Karl Berry <karl@gnu.org>

2312 2006-10-13 Stepan Kasal <kasal@ucw.cz>
2314 * doc/autoconf.texi (Autoheader Macros): Warn that the text
2315 added to the template can get mangled.
2317 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2319 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
2320 include the default headers, and redefine obstack_chunk_alloc

2327 by Ralf Wildenhues.
2329 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2343 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
2344 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
2345 Use a better substitute, by inspecting the output of "ls"
2346 rather than just using ":".
2347 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
2348 rather than AS_EXECUTABLE_P, since we needn't worry about
2349 non-regular files here.
2351 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
2352 due to configuration hassles with this. See Tonya Underwood's report

2367 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
2369 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
2371 * doc/autoconf.texi (Limitations of Usual Tools): Describe
2372 problems with mkdir -p -m.
2374 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
2376 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
2377 comment about ac_cpp_err; it was incorrect, and anyway
2378 ac_cpp_err is being removed below.
2379 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
2380 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
2381 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
2382 nobody uses it.
2383 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
2384 with werror_flag and conftest.err and so forth. This is more
2385 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
2386 and anyway the user shouldn't normally want to see this gorp logged.
2387 Problem reported by Ralf Wildenhues.
2388 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
2389 empty, not 'no', since the rest of the code uses 'test -z'.
2391 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
2393 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2394 Use a single call to AC_DO_TOKENS rather than multiple, for
2395 efficiency.
2396 (_AC_LINK_IFELSE): Test that resulting file is executable.
2397 Problem reported by mwoehlke in
2398 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
2400 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
2401 than creating a file to use with test -x; this is much faster.
2403 2006-10-02 Bruno Haible <bruno@clisp.org>
2405 * lib/autom4te.in (Automake-preselections): Add
2406 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
2408 2006-09-27 Stepan Kasal <kasal@ucw.cz>
2410 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
2411 standard error, `experr' should be used, not `expout'.
2413 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
2415 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
2416 fseeko testing program twice; just use the earlier result.
2417 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2418 Set cache var to 'unknown' (not 'no') if leaving the macro unset
2419 still doesn't let the program compile.
2420 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
2421 failed.
2423 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
2424 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
2425 include it, without including anything else.
2426 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
2427 expressions.
2428 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
2430 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2432 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
2433 `error.h', and include it, for a `error_at_line' prototype.
2434 Use a nonempty format string in the link test.
2435 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
2436 for a declaration of wait3.
2438 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
2440 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
2441 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
2442 can apply to constants too, and that it checks for macro defns.
2443 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
2444 and simply cast the identifier to void. This handles structure
2445 values. Problem reported by Ralf Wildenhues.

2448 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2518 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
2519 mistaken comment: the path has to be relative; do not use
2520 the path at runtime.
2522 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2524 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

2534 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
2535 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
2536 for the existence of the directory at configure-time. That's
2537 too late, anyway. Problem reported by Stefan Seefeld.
2539 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
2540 7.1.4 /usr/bin/posix/sh described by Tim Rice in
2541 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
2543 2006-09-11 Stepan Kasal <kasal@ucw.cz>
2545 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
2546 works with GNU M4 1.4.3 again; make the normalized form
2547 match the current m4 message; fix the description.
2548 * test/tools.at (autom4te cache): Adapt to the change.
2550 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
2552 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
2553 to catch glibc bug 2821
2554 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
2556 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
2557 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
2558 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
2559 assume C89.

2581 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
2582 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
2583 accept files with extension `.f'. For consistency, also prefer
2584 xlf over f77.
2585 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
2586 from last patch.

2607 except the first two arguments are reversed.
2608 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.

2657 deal with LEXLIB.
2658 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
2659 didn't work if some values were cached but not others. Test for
2660 broken lex libraries like native ia64-hp-hpux11.22; see
2661 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
2662 work around the problem by preferring an empty LEXLIB to -lfl or
2663 -ll. Let the user set LEXLIB='' to indicate no library needed.
2665 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
2666 * README: Likewise.

2808 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
2809 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
2810 this.
2812 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
2814 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
2815 problems with arg script text that doesn't end in newline, and
2816 with '-e a...'. Problems reported by Ralf Wildenhues.
2818 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
2820 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
2821 check for libXt by a check for libX11.
2823 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2825 * doc/autoconf.texi (config.status Invocation): Adjust according
2826 to last change.
2828 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2830 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
2831 --help' should mention that `--version' outputs configuration
2832 settings. Report by Bruno Haible.
2834 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
2836 Fix test suite failures reported by Pierre in
2837 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
2838 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
2839 the compiler created a file "b.out" when it didn't create anything
2840 at all.
2841 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
2842 Discard stderr too, when invoking the test script.
2844 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
2846 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
2847 in the restoring of the werror flag.
2849 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
2851 * doc/autoconf.texi (Volatile Objects): Be even a little
2852 less skeptical about "volatile", after discussion with
2853 Bruno Haible on bug-gnulib.
2854 (Limitations of Usual Tools): Warn about sed stripping
2855 leading white space from text. From Bruno Haible.
2857 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
2859 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
2860 compiler complains about it, even if things works after the
2861 complaint. Problem reported by Peter O'Gorman.
2863 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
2864 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
2865 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
2867 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
2869 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
2870 after -R regardless of host. Patrick Welche reports that this
2871 fixes things on NetBSD 3.99.
2873 * NEWS: Recommend M4 1.4.5.
2874 * README: Likewise.
2875 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
2876 * tests/tools.at (autom4te cache): Update wording of diagnostic
2877 to match M4 1.4.5.
2879 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
2881 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
2882 under AC_C_VOLATILE.
2883 (Volatile Objects): Be a little less skeptical about what
2884 "volatile" means. Derived from thoughts by Ben Pfaff in
2885 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
2887 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2889 * doc/autoconf.texi: Fix some typos.
2891 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
2893 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2894 more globally, since the 2006-06-30 patch didn't suffice. Problem
2895 reported by Keith Marshall. Also, don't bother with builddir2,
2896 since it shouldn't be needed any more.
2898 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
2900 * doc/autoconf.texi (Generic compiler characteristics):
2901 Document AC_COMPUTE_INT. Fix wrong statements on Default
2902 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
2904 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
2905 (_AC_COMPUTE_INT): Add obsoletion warnings.
2906 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
2907 AC_COMPUTE_INT.
2909 * NEWS: Document change.
2911 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
2913 * doc/autoconf.texi (Volatile Objects): New section.
2915 * NEWS: Document previous change.
2917 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
2919 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
2920 Require that long long int be at least 64 bits wide. C99 requires
2921 this and enough programs depend on it so we should check for it.
2922 Bruno Haible reports in
2923 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
2924 that long long int is 32 bits wide with some nonstandard compilers.
2925 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
2927 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
2929 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2930 to a nonexistent file, so that we don't have to worry about
2931 a local site configuration that doesn't use /usr/local.
2932 Problem reported by Keith Marshall in
2933 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
2935 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
2937 * doc/autoconf.texi: Be more consistent about using @acronym with
2938 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
2939 quite right (it talked about "OSF/Tru64", even though the
2940 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
2941 and it even mentioned "OSF 4"!) and at this point there's little
2942 reason to talk about OSF any more, since it died in 1994.
2943 (Specific Compiler Characteristics): Simplify example of
2944 negative-size array.
2945 (File Descriptors): Reorder to make the text flow better.
2946 Remove joke about "appreciate the various levels"; I didn't get it.
2947 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
2948 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
2949 (File Descriptors, Limitations of Usual Tools):
2950 Tone down the advice against renaming or removing open files.
2951 (Limitations of Usual Tools): Add a new section, on 'rm'.
2953 2006-06-26 Stepan Kasal <kasal@ucw.cz>
2955 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
2956 -lXt in LIBS, idea from Karsten Hopp; this was due since
2957 this change:
2959 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2960 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2961 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2962 (which belong to Xt, not X itself). See Debian bug 327655.
2964 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2966 * configure.ac (AC_INIT): Bump to 2.60a.
2967 * NEWS: Update.
2969 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2971 Version 2.60.
2973 * configure.ac, NEWS: Update.
2975 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2977 * config/texinfo.tex: Sync from upstream.
2979 * bin/autom4te.in (handle_traces): Transform the `@S|@'
2980 quadrigraph correctly in traces.
2982 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
2983 Fix typos.
2985 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
2986 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
2987 not defined.
2988 * doc/autoconf.texi (Changed Directory Variables): New node,
2989 to document the whole `datarootdir' business a bit better.
2990 * NEWS: Update.
2991 * tests/torture.at (datarootdir workaround): Extend test.
2992 Prompted by report by Alexandre Julliard.
2994 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
2996 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
2997 when using default mode of IBM C 6 for AIX. Problem and two-line
2998 fix reported by Larry Jones.
3000 2006-06-22 Alexandre Julliard <julliard@winehq.org>
3002 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
3003 about literal '${datarootdir}' if a definition is found in the
3004 output file.
3006 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
3008 * NEWS: Use "M4" rather than "m4" when appropriate.
3009 Problem reported by Eric Blake.
3010 * doc/autoconf.texi: Likewise.
3011 Use @acronym around BSD, GCC, and GNU when appropriate.
3012 (Why GNU M4): Renamed from "Why GNU m4".
3013 (Redefined M4 Macros): Mention that Posix
3014 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
3015 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
3016 to int.
3018 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3020 * bin/autom4te.in (handle_output): Do not forbid the empty
3021 pattern.
3022 * tests/tools.at (autoconf: the empty token): New test.
3024 2006-06-20 Stepan Kasal <kasal@ucw.cz>
3026 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
3027 calls, so that we do not care whether they are LIFO or FIFO;
3028 in the m4_wrap, do not check which diversion is the topmost
3029 one, just check that the stack is balanced at the end.
3030 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
3031 base diversion forever--pop the previous diversion before
3032 opening the new one; consequently, remove the m4_wrap call.
3033 * lib/autotest/general.m4 (AT_INIT): Likewise.
3034 * tests/m4sugar.at: Do not use
3035 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
3037 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
3038 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3040 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
3041 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
3042 Rework example of m4wrap token-pasting trouble so that it doesn't
3043 care whether it's LIFO or FIFO.
3044 Fix some "contrary to"s that are awkward in English.
3046 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3048 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
3049 to `yes' instead of `int$1_t' if the type is found, for more
3050 consistent configure output (where $1 is the number of bits).
3051 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
3052 Suggested by Bruno Haible.
3054 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
3055 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
3056 with system headers. Report by Bruno Haible.
3058 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3060 * config/config.guess, config/config.sub: Sync from upstream.
3062 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
3063 in order to avoid picking up an older installed frozen m4sh.m4f.
3064 Besides an outdated shell startup, this could have been created
3065 by an earlier M4 version with incompatible frozen file format.
3067 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
3069 * README: Recommend m4 1.4.4 instead of 1.4.3..
3070 * doc/autoconf.texi: Likewise.
3071 (Special Chars in Names): Say that $(.FOO) is portable, as
3072 suggested by Stepan Kasal.
3073 (Installation Directory Variables, Build Directories):
3074 (Automatic Remaking, Subdirectories, Fortran Compiler):
3075 (Making testsuite Scripts, Defining Directories):
3076 Quote variable usages better.
3077 (Making testsuite Scripts): Add clean-local rule to makefile
3078 snippet, by Eric Blake.
3079 (Installation Directory Variables): Fix table item font.
3080 Reword slightly to clarify. Generalize advice about
3081 not using special characters to include all file-related
3082 vars, not just VPATH.
3083 (Special Chars in Variables): Warn about special characters in
3084 $(srcdir) too.
3085 (Assignments): Clarify default-value example as suggested by
3086 Ralf Wildenhues in
3087 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
3088 (Special Shell Variables): Note leading ./ or ../, as suggested
3089 by Eric Blake.
3090 (Limitations of Builtins): Under cd, warn about CDPATH.
3091 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
3092 Ralf Wildenhues.
3094 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3096 * doc/autoconf.texi (Configuration Actions): Remove duplicate
3097 `@var', for texi2html.
3098 (Systemology): Some more word wrapping, for DVI output.
3099 (autom4te Invocation): The short option for `--melt' is `-M',
3100 not `-m'.
3102 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
3104 * doc/autoconf.texi: More formatting and English tweaks,
3105 many suggested by Ralf Wildenhues.
3106 Reword to avoid "@code{...}'s" and the like, since it's ugly
3107 with Emacs info mode. discontents -> woes.
3108 Put a few "will"s back. time stamp -> timestamp.
3109 side-effect -> side effect.
3111 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
3113 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
3114 Warn about $@ not persisting. Problem reported by Julien Danjou in
3115 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
3116 (Special Chars in Names): Renamed from Leading _ in Macro Names.
3117 Mention other special chars, too.
3119 2006-06-14 Eric Blake <ebb9@byu.net>
3121 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
3123 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
3125 * doc/autoconf.texi: Some systematic minor improvements, as
3126 follows. Use "makefile" when talking about makefiles
3127 generally (which might be named "makefile" or "Makefile" or even
3128 "foo.mk"), "Makefile" when talking about a specific makefile
3129 called "Makefile". This unclutters the text from weird quotes
3130 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
3131 values" rather than "@var{foo}s" and similar constructs containing
3132 "}s". Use "Make rules" rather than "Makefile rules". Minor
3133 English-language improvements. Change the prefix "sub-" to "sub"
3134 and "re-" to "re".
3135 Put blank lines around examples more consistently.
3136 Avoid "rather" and "very" as intensifiers.
3137 Avoid "will" as an auxiliary.
3138 (Limitations of Make): Split this node into....
3139 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
3140 (Leading _ in Macro Names, Backslash-Newline-Newline):
3141 (Backslash-Newline Comments, Long Lines in Makefiles):
3142 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
3143 (obj/ and Make, make -k Status, VPATH and Make):
3144 (VPATH and Double-colon, $< in Explicit Rules):
3145 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
3146 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
3147 New nodes, resulting from splitup of Limitations of Make.
3148 All cross-references changed. Raise the top node from
3149 a section to a chapter, and all subnodes accordingly.
3150 Redo the introductory wording to match the new organization.
3151 (Installation Directory Variables): Use an example that is
3152 closer to what Autoconf actually does. Mention that VPATH's
3153 value should not contain metacharacters or white space.
3154 (Fortran Compiler): Fix a VPATH bug in an example.
3155 (Leading _ in Macro Names): Mention that this problem is no longer
3156 of practical concern.
3157 (VPATH and Make): Reword the advice to make it clearer
3158 that Autoconf and Automake support VPATH in non-GNU make, but
3159 many packages have bugs in this area.
3160 ($< in Explicit Rules): Refer to Build Directories rather
3161 than using a (non-VPATH-safe) example.
3162 (Automatic Rule Rewriting): Mention the sort of disaster that
3163 can ensue with Solaris-style rule rewriting with VPATH.
3165 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3167 * doc/install.texi (Compilers and Options): Weaken the
3168 suggestion to use GNU make for VPATH builds.
3170 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
3171 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
3173 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
3174 in regular expression.
3176 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3178 * doc/autoconf.texi (Installation Directory Variables):
3179 Drop extra @samp from `@table @samp' item.
3180 (Limitations of Usual Tools): Comment fix.
3181 Do not nest @samp just to point to other table items.
3182 (Writing testsuite.at) <AT_CHECK>: The second argument to
3183 `@dvar' is already @samp'ed.
3184 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
3185 do not use @var in the second argument.
3187 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
3189 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
3190 $as_shell.exe too. Problem reported by Andreas Buening in
3191 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
3193 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3195 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
3196 `unused variable' compiler warning, for `-Wall -Werror'.
3197 Reported by Jaap Haitsma in
3198 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
3200 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
3202 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
3203 case the compiler dumps core. Problem reported for
3204 OpenServer 5.0.7 by Tim Rice in
3205 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
3206 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
3207 Likewise.
3209 2006-06-06 Tim Rice <tim@multitalents.net>.
3211 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
3212 "ERROR" only shows up in "make check" output if there is an
3213 error.
3215 2006-06-06 Eric Blake <ebb9@byu.net>
3217 * tests/tools.at (automatically allowed tokens): Fix typo.
3219 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3221 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
3223 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
3224 typically overflows on x86 CPUs, even though the C standard
3225 requires otherwise.
3227 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3229 * configure.ac (AC_INIT): Bump to 2.59e.
3230 * NEWS: Update.
3232 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3234 Version 2.59d.
3236 * config/texinfo.tex: Sync from upstream.
3238 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
3239 seen, invoke libtoolize with `--ltdl' argument.
3240 * lib/autom4te.in (Autoreconf-preselections): Adjust.
3241 * NEWS: Update.
3242 Suggested by Eric Blake.
3244 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3246 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
3247 reported by Ralf Wildenhues.
3248 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
3250 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3261 message issued by AC_REQUIRE.
3262 * tests/m4sugar.at: Check m4_require's error message.
3263 * tests/base.at: Check AC_REQUIRE's error message.
3264 * tests/local.at (AT_CHECK_M4): New macro, almost identical
3265 to...
3266 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
3267 AT_CHECK_M4.
3268 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
3269 `expout' as the last parameter.
3270 * tests/tools.at: Adapt to the above change.
3272 2006-06-04 Stepan Kasal <kasal@ucw.cz>
3274 * doc/autoconf.texi (Limitations of Usual Tools): Correct
3275 information about race-free implementations of mkdir.
3277 2006-06-04 Eric Blake <ebb9@byu.net>
3279 * bin/autoreconf.in (help): Document M4 environment variable.
3280 * bin/autoconf.as (Usage): Likewise.
3281 * bin/autom4te.in (help): Likewise.
3282 * doc/autoconf.texi (autom4te Invocation): Likewise.
3284 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
3286 * NEWS: GNU make now recommended for VPATH builds.
3287 Mention that some macros are now documented to be obsolescent.
3288 * doc/autoconf.texi:
3289 Prefer "current" to "modern" to describe
3290 currently-used (albeit perhaps old-fashioned) hosts.
3291 Mention which ancient features no longer need to be worried about.
3292 setgid -> set-group-ID
3293 setuid -> set-user-ID (these are the Posix terms)
3294 Fix some misuses of "only".
3295 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
3296 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
3297 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
3298 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
3299 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
3300 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
3301 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
3302 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
3303 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
3304 Mention that these macros are obsolescent.
3305 (Installation Directory Variables): shall -> should
3306 (File Descriptors): Mention that 0, 1, 2 might get reopened.
3307 Mention that it's now safe to use 3 and 4.
3308 (Limitations of Usual Tools): cp -r is now specified by Posix.
3309 Omit longwinded and obsolescent discussion of cp -f.
3310 Modernize discussion of expr, ls.
3311 (Limitations of Make): Modernize discussion of VPATH builds.
3312 Mention $? as a workaround in some cases.
3313 * doc/install.texi (Basic Installation):
3314 Mention "./configure; make; make install" first. Be more
3315 specific about why this file is generic. Remove unnecessary
3316 parens. Remove misleading "only". Remove obsolete advice
3317 about csh. Don't say "configure" takes awhile; say it
3318 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
3319 and CC=c99 rather than CC=c89, as these are blessed by current
3320 Posix. Recommend GNU make if doing a VPATH build.
3322 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
3324 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
3325 examples involving shell prompts.
3327 2006-06-02 Stepan Kasal <kasal@ucw.cz>
3328 and Paul Eggert <eggert@cs.ucla.edu>
3330 * doc/autoconf.texi (Here-Documents): Add details about the
3331 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
3332 use "here-documents" instead of "here documents".
3334 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3336 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
3338 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
3340 * doc/autoconf.texi (File System Conventions): Warn about ":"
3341 anywhere in directory names.
3343 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
3345 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
3346 about quoting the case statement, just in case.
3347 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
3348 was fixed in ksh93g; reported by Ralf Wildenhues.
3350 2006-05-31 Stepan Kasal <kasal@ucw.cz>
3352 * doc/autoconf.texi (System Services): Do not document
3353 overriding EXEEXT via ac_cv_exeext=ext.
3354 (Particular Programs) <AC_PROG_MKDIR_P>:
3355 Document that ${MKDIR_P} understands --.
3356 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
3357 comment.
3359 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3361 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
3362 argument with leading hyphen. Problem reported by Paul Eggert.
3364 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3366 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
3367 about quoting ac_try: quote all of it, if any of it seems suspicious.
3368 This means we don't have to worry about ${ or sed any more.
3369 Also, double-quote the case statement, to work around misuses via
3370 underquoting as reported by Ralf Wildenhues in
3371 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
3372 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
3373 undocumented and dangerous macro.
3374 Problem reported by Ralf Wildenhues in
3375 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
3377 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3379 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
3380 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
3381 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
3383 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3385 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
3386 since evidently some packages rely on the old, broken behavior.
3387 Problem reported by Ralf Wildenhues in
3388 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
3389 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
3390 pre-2006-05-26 definitions, but leave in the comments that
3391 these macros are dangerous and should not be used.
3392 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
3393 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
3394 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
3395 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
3396 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
3398 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
3400 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
3401 the use of 'tr', since this is our only use of 'tr'.
3403 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3404 and Paul Eggert <eggert@cs.ucla.edu>
3406 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
3407 Don't assume 'grep' works on long lines, since AIX grep doesn't.
3409 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3411 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
3412 the output file in the `${datarootdir}' test.
3414 2005-05-28 Stepan Kasal <kasal@ucw.cz>
3415 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3417 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
3418 mention of `datarootdir' in the input file(s), but literal
3419 `${datarootdir}' in the output file, and we haven't warned yet,
3420 then warn as well: the user may have (erroneously) used
3421 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
3422 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
3423 * tests/torture.at (datarootdir workaround): Extend this test.
3424 * NEWS: Update.
3426 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3427 and Paul Eggert <eggert@cs.ucla.edu>
3429 * doc/autoconf.texi (autoheader Invocation): The first argument to
3430 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
3431 alternatives and clear up the language a bit.
3433 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
3435 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
3436 ac_config_guess, ac_config_sub, ac_configure.
3437 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3438 Fix typo that prevented an unnecessary space from being removed.
3439 Problems reported by Ralf Wildenhues in:
3440 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
3442 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
3444 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
3445 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
3446 Don't use the term "thread-safe" to talk about mkdir race
3447 conditions, since the problem is more a process than a thread
3448 issue. Problem reported by Stepan Kasal in:
3449 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
3450 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
3451 the test for 'install' more closely. Look at MKDIR_P first.
3452 Look in the PATH, and at /opt/sfw/bin.
3453 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
3454 Don't bother to try mkdir -p, since we already check mkdir --version;
3455 just look at the version number. (There's no easy way to check
3456 for race-free implementations.)
3457 * tests/tools.at (autoconf: subdirectories): Adjust to above
3458 changes, since MKDIR_P now might end in "/mkdir -p".
3460 * doc/autoconf.texi (autoheader Invocation): Mention that the
3461 first arg of AC_DEFINE_UNQUOTED must be a literal.
3462 Problem reported by Ben Pfaff in
3463 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
3465 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
3466 * doc/autoconf.texi (Special Chars in Variables): New section.
3467 (Preset Output Variables): Warn about special chars in CPPFLAGS.
3468 (Installation Directory Variables): Quote $(datadir) better.
3469 (Limitations of Builtins): Describe some of eval's trickiness.
3471 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
3472 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
3473 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
3474 in front of every arg, not just trailing args. Quote apostrophes.
3475 (_AC_EVAL_ECHO): New macro.
3476 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
3477 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
3478 removed.
3479 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
3480 exposed by quoting of eval argument. Put the command on line line
3481 so it logs better.
3482 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
3483 (_AC_PATH_X, AC_PATH_X): Quote more safely.
3484 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
3485 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
3486 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
3487 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
3488 Use eval more safely.
3489 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
3490 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
3491 to be replaced.
3492 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
3493 lines, exposed by quoting of eval argument.
3495 2006-05-26 Stepan Kasal <kasal@ucw.cz>
3496 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3498 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
3499 initialization of `ac_cv_exeext', do not override it if it was
3500 already set, unless it was set to `no', for compatibility with
3501 Autoconf-2.13, and comment this.
3502 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
3503 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
3504 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
3505 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
3506 Document that this test may be overridden by setting
3507 `ac_cv_exeext'.
3509 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3511 Revert these two patches:
3513 2006-04-06 Eric Blake <ebb9@byu.net>
3514 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3515 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3516 2006-04-01.
3518 2006-04-01 Stepan Kasal <kasal@ucw.cz>
3519 Clean up _AC_COMPILER_EXEEXT* macros.
3520 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3521 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3522 ac_file to the name of the default output file and call
3523 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3524 initial `rm' of the candidate files...
3525 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3526 the same list in subsequent `rm' calls, and for the temporary
3527 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3528 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3529 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3530 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3531 no longer needed) by libtool. Make it a cache check.
3532 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3533 copied here by mistake.
3534 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3535 _AC_COMPILER_EXEEXT.
3536 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
3537 _AC_COMPILER_OBJEXT directly.
3538 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3540 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3542 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
3543 Fix description of how the buggy `sed' works.
3545 2006-05-25 Noah Misch <noah@cs.caltech.edu>
3547 Sync from Automake:
3549 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
3550 ENOLCK. Only mention `make -j' when applicable. Only raise
3551 fatal errors when `make -j' is involved. Improve error message.
3553 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3555 * doc/autoconf.texi (Here-Documents): We now know more about
3556 the variable expansion in here documents bug.
3557 Thanks to Tim Rice and Stepan Kasal.
3559 * doc/autoconf.texi (Making testsuite Scripts): Add an example
3560 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
3562 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3564 * tests/autotest.at (Multiline command from M4 expansion):
3565 No failure to be expected if the shell quotes newlines in
3566 commands in the `set -x' output. Report by Tim Rice.
3567 * THANKS: Update.
3569 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3571 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
3572 expansion in the here-documents used by config.status, as that
3573 runs afoul of the Korn shell version M-12/28/93d bug described in
3574 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
3575 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
3576 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
3578 2006-05-23 Jim Meyering <jim@meyering.net>
3580 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
3581 Fix typo introduced with 2006-04-02 change. It reversed the sense
3582 of the test.
3584 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3586 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
3587 ac_dB slightly, to save bytes in the script.
3588 Max out at 50 lines, rather than 96; this is more likely
3589 (though not guaranteed) to avoid obscure 'sed' failures.
3591 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3593 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
3594 `tr -d -' as bad option argument. Work around this by deleting
3595 an unrelated character.
3596 Report by Tim Rice <tim@multitalents.net>.
3598 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
3599 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3600 Stepan Kasal <kasal@ucw.cz>
3602 * doc/autoconf.texi (Particular Programs): Do not promise that
3603 we always prefer the GNU version of the program, and that we
3604 search according to PATH; both rules can have exceptions.
3605 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
3606 AC_PROG_SED. Move descriptions of limitations
3607 to the Limitations of Usual Tools section.
3608 (Limitations of Usual Tools) <sed>: Mention script length
3609 limitations with Solaris /usr/ucb/sed.
3610 <grep>: Fix wording for empty alternative. Mention that -c and
3611 -l should not be combined, and that -E and -F should not be
3612 combined.
3614 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3615 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3617 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
3618 limits in Solaris 8 /usr/ucb/sed by testing a long script.
3620 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3622 * doc/autoconf.texi (Defining Symbols): Literal parameter of
3623 AC_DEFINE is now passed to m4_pattern_allow.
3624 * NEWS: Mention that; likewise for AC_SUBST.
3625 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
3626 the parameter to m4_pattern_allow.
3627 * tests/tools.at: Add a check for that.
3629 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3631 * lib/autoconf/status.m4: Fix typos.
3633 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3635 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
3636 only the files that this macro generates.
3638 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3640 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
3641 the HP-UX sed limitation of 99 commands, labels do not count.
3642 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
3643 in the comment.
3644 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
3646 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3648 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3649 Import the following fix from coreutils:
3651 2006-01-13 Jim Meyering <jim@meyering.net>
3653 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
3654 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
3655 not double-quote uses of that variable, to accommodate the rare
3656 case in which getmntent is available in none of the libraries
3657 checked. This happens at least on FreeBSD 5.0.
3659 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
3661 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
3662 ac_config_guess, ac_config_sub, and ac_configure, since evidently
3663 some other programs unwisely rely on these undocumented vars.
3664 But put in warning comments about them.
3665 Problem reported by Ralf Wildenhues in
3666 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
3667 * NEWS: Document that these variables are intended to go away.
3669 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3671 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
3672 and set the language to C++ (analogous to the equivalent Fortran
3673 tests).
3675 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
3676 * doc/autoconf.texi (C++ Compiler): Document it.
3677 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
3678 * NEWS: Update.
3680 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
3682 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
3683 that caused config.status to generate 100-command sed scripts; the
3684 portable limit is 99.
3686 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3688 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
3689 variable `ac_d' instead of `d' to avoid infringing namespace.
3690 Report by Ralf Menzel.
3692 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
3694 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
3695 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
3696 * tests/tools.at (autoconf: subdirectories): New test, taken from
3697 the corresponding problem report by Ralf Wildenhues in:
3698 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
3700 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
3701 Quote some uses of shell variables if they might suffer unexpected
3702 globbing. This doesn't fix all instances of quoting problems that
3703 I found, just the easy ones that look safe.
3704 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
3705 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
3706 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
3707 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
3708 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
3709 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
3710 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
3711 Likewise.
3712 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
3713 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
3715 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3717 * bin/autoreconf.in ($help): Reword according to the manual.
3718 Suggested by Olly Betts.
3720 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
3721 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3723 * bin/autoreconf.in: Pass the directory argument to
3724 `require_configure_ac'. Fix comment.
3725 * tests/torture.at (Configuring subdirectories): Expose this.
3726 Reported by Olly Betts.
3728 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3730 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
3731 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
3732 Automake as follows:
3734 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
3735 `$configure_in' instead of `configure.in', to preserve
3736 directory component.
3738 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3740 * config/config.guess, config/config.sub, config/texinfo.tex,
3741 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
3743 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
3745 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
3746 test for C99 conformance; (bool) 0.5 is an integer constant
3747 expression, but (bool) -0.5 is not. Problem reported by Fedor
3748 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
3750 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
3752 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
3753 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
3754 Warn about obsolete install-sh files. Remove stray sentence
3755 fragment and fix cross reference.
3756 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
3757 install -d; this undoes the 2006-05-10 change.
3758 (MKDIR_P): Mark with AN_MAKEVAR.
3759 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
3760 that we don't require $INSTALL to be thread-safe. Move comments
3761 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
3762 of AC_PROG_INSTALL. Output a message saying that we're checking
3763 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
3764 MKDIR_P instead of AC_SUBST.
3765 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
3766 Special magic for MKDIR_P, too.
3767 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
3768 a dnl.
3769 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
3771 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
3773 Sync from Automake, as follows:
3775 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3776 * config/install-sh: Initialize IFS, so field splitting isn't
3777 turned off later.
3778 * config/mkinstalldirs: Likewise.
3779 * config/missing: Remove superfluous quotes. Replace all uses of
3780 `[' by `test', for consistency, and for..
3781 * config/missing (sed_minuso, sed_output): New variables.
3782 (autom4te, help2man, makeinfo): Use them. Unifies detection of
3783 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
3784 Fixes `missing' to detect `--output' for help2man. Fixes
3785 PR automake/483. Report by Dennis J. Linse.
3786 (autom4te): Document in `missing --help'.
3788 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3790 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
3791 * config/install-sh: Don't use 'path' to talk about file names,
3792 as per GNU coding standards. Close a race condition reported by Ralf
3793 Wildenhues and Stepan Kasal. There is still a race condition
3794 on hosts that predate Posix 1003.1-1992, but we can't help this.
3795 Don't mishandle weird characters like space on pre-Posix hosts.
3796 Invoke mkdir at most once per dir arg on pre-Posix hosts.
3797 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
3798 AC_PROG_MKDIR_P from AS_MKDIR_P.
3799 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
3800 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
3801 earlier editions are not (including Automake 1.8.3).
3802 Do not suggest mkinstalldirs for thread-safety.
3803 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
3804 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
3805 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
3806 presence of special characters and race conditions.
3807 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
3808 in Autoconf's name space.
3810 2006-05-10 Bruno Haible <bruno@clisp.org>
3811 and Paul Eggert <eggert@cs.ucla.edu>
3813 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
3814 from Automake with minor changes.
3815 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
3817 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3819 * config/install-sh: Update to Automake CVS version, as follows:
3820 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3821 * lib/install-sh: Simplify the expr implementation of dirname.
3822 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
3823 * lib/install-sh: Handle --, and diagnose unknown options.
3825 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3827 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
3828 `./autom4te' to create `./testsuite', since the `all' target
3829 will ensure its presence, but `installcheck' should not create
3830 the uninstalled wrappers.
3832 * tests/torture.at (Unusual Automake input files): Skip if we
3833 detect automake < 1.8.
3835 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3837 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
3838 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
3839 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
3840 * NEWS: Update.
3842 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3844 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
3845 munge (multiple) white space and other oddities.
3846 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
3847 single quotes in variable assignment.
3848 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
3849 and similar failures by adding multiple spaces, tabs, and other
3850 special characters.
3851 Report and different test suggested by Francesco Romani
3852 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
3854 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
3855 single quotes, we only need to search for single quotes; this
3856 both simplifies the search pattern, and makes us less
3857 susceptible to `echo' variations for arguments not containing
3858 single quotes.
3859 (_AC_ARG_VAR_VALIDATE): Likewise.
3861 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3863 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
3864 `$*' and IFS concatenation issue with traditional shells and
3865 bash-2.04. Report by Seanster@Seanster.com.
3867 2006-05-03 Bruno Haible <bruno@clisp.org>
3869 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
3870 precisely which Mac OS X versions have the od problem.
3872 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3874 * doc/autoconf.texi: Use @option systematically.
3876 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3877 and Bruno Haible <bruno@clisp.org>
3879 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
3880 about 'od'.
3881 (Integer Overflow): Mention the special case of integer division
3882 overflow.
3884 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3886 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
3887 traditional shells like the Solaris one that do not use the
3888 first IFS character for assembling `$*'.
3889 Prompted by a related report from autoconf_bug@nro.ca.
3891 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
3892 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3894 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
3895 Mention more problems with the -e option.
3897 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3899 * NEWS: Typo.
3900 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
3902 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
3903 in URLs to improve DVI formatted output (requires texinfo 4.6).
3904 (System Services, Systemology, Shellology): Likewise.
3905 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
3906 output.
3908 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
3909 continuous text.
3910 (Runtime): Fix macro argument names to match description:
3911 `action-if-found' -> `action-if-true' and similarly.
3912 (Obsolete Macros): Likewise.
3913 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
3914 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
3915 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
3917 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3919 * doc/autoconf.texi (Limitations of Make): Clean up markup.
3921 * ChangeLog: Typo.
3922 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
3923 DVI output.
3925 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3927 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
3928 /bin/sh set unsorted output.
3929 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
3930 * tests/local.at: Likewise.
3932 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
3934 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
3935 (Integer Overflow, Null Pointers, Buffer Overruns):
3936 (Floating Point Portability, Exiting Portably): New sections.
3937 (Writing Test Programs): Fix some langauge. Recommend exiting
3938 with status 1, not merely nonzero. Clarify exit declaration.
3939 (Run Time): Move C exit status stuff to new Exiting Portably section.
3940 (Systemology): Mention Posix and levenez. Update v7 reference.
3941 (Portable Shell): Mention the Posix shell.
3943 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3945 * bin/autoconf.as (me): Replace by as_me.
3947 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
3949 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
3950 since as_me isn't set yet.
3952 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3954 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
3955 a few minor bugs in this area.
3957 * doc/autoconf.texi (Programming in M4sh): Comment out the
3958 documentation of AS_BASENAME, for now.
3959 (Shell Substitutions): Do not use AS_DIRNAME in an example.
3960 (Limitations of Builtins) <basename>: Do not refer to
3961 AS_BASENAME.
3962 * bin/autoconf.as (me): Don't use AS_BASENAME.
3963 (dir): Remove the unused variable.
3964 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
3965 AS_DETECT_REQUIRED. All uses changed.
3966 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
3967 All uses changed.
3968 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
3969 (AS_BASENAME): Use "basename --" to protect against leading "-".
3970 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
3971 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
3972 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
3973 (_AS_DIRNAME_PREPARE): Likewise.
3974 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
3975 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
3976 (AS_DIRNAME): Use "dirname --".
3978 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3980 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
3981 of "run time" and "run-time" changed to "runtime", for consistency.
3982 * lib/autoconf/fortran.m4: Likewise (in comment).
3983 * lib/autoconf/functions.m4: Likewise.
3984 * lib/autoconf/general.m4: Likewise.
3985 * lib/autoconf/headers.m4: Likewise.
3987 * doc/autoconf.texi (Run Time): Document the exit status situation
3988 with more accuracy and detail.
3990 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3992 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
3993 Archive is not officially `GNU' any more. Update URL.
3994 (Defining Directories): Likewise
3995 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
3997 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3999 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
4000 newline from the `trap' code to finish `config.log'; the NetBSD
4001 /bin/sh resets the exit status after an empty command, as
4002 documented in doc/autoconf.texi.
4003 Reported by Dalibor Topic <robilad@kaffe.org>.
4005 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
4007 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
4008 Suggested by Bruno Haible.
4010 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
4012 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
4013 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
4014 Instead, just list the shells that we know work.
4015 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
4016 changed. Be more cautious about the _cv_ variable.
4017 * tests/tools.at (Syntax of the shell scripts): Check the
4018 _cv_ variable once, at first, to avoid an internal autoconf error
4019 when sh -n does not work.
4021 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4023 * lib/Autom4te/FileUtils.pm: Sync from Automake.
4025 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
4027 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
4028 use ">&-" since we're only 99.999% sure that this is portable,
4029 and since the MinGW bug is fixed in a different way.
4030 * lib/autotest/general.m4 (AT_INIT): Likewise.
4032 2006-04-16 Stepan Kasal <kasal@ucw.cz>
4034 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
4035 before opening config.log, to avoid hitting a bug on MinGW.
4037 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
4039 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
4040 AS_MESSAGE_LOG_FD before reopening it onto the log file.
4041 This works around a MinGW bug reported by Eric Paire.
4042 Make sure that all writes to the log file append to it,
4043 rather than possibly losing data.
4044 * lib/autotest/general.m4 (AT_INIT): Likewise.
4046 2006-04-14 Stepan Kasal <kasal@ucw.cz>
4048 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
4049 description.
4051 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4053 * NEWS: Update.
4055 * configure.ac (AC_INIT): Bump to 2.59d.
4057 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4059 Version 2.59c.
4061 * Makefile.maint (news-date-check): Do not require a leading `*'
4062 before the release date in NEWS.
4064 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4065 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4067 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
4068 the instantiated file do not contain the string 'datarootdir'
4069 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
4070 @mandir@, replace the reference '${datarootdir}' by the value.
4071 * tests/torture.at (datarootdir workaround): New test.
4072 * NEWS: Advertise this temporary fixup.
4073 Based on a patch by Bruno Haible, reported and analyzed by
4074 Paul Eggert and Noah Misch.
4076 2006-04-12 Eric Blake <ebb9@byu.net>
4078 * tests/autotest.at (Debugging a failed test): Fix comment.
4080 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4082 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
4083 all the changes since 2006-04-07.
4085 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4087 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
4088 succeeded, but `ln -s file dir' failed, take care to remove the
4089 leftover target before the next test, to prevent its spurious
4090 failure; also make sure `ln file dir' works before selecting it.
4091 Thanks to Keith Marshall for pointing this out.
4092 * THANKS: Update.
4094 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
4095 assignments in `at_debug_args', so that we put them correctly
4096 in the `run' script.
4097 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
4098 Reported by Eric Blake.
4100 2006-04-11 Eric Blake <ebb9@byu.net>
4102 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
4103 top-level tests after micro-suite has been run. Used in...
4104 (Debugging a successful test, Debugging script and environment),
4105 (Debugging a failed test): ...these new tests. The first of these
4106 is fixed by...
4107 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
4108 macro, split out from...
4109 (AT_INIT): ...here, so that using -d also generates a run script.
4110 Document that -d inhibits top-level logging.
4111 * doc/autoconf.texi (testsuite Invocation): Document that -d only
4112 inhibits top-level logging; debug scripts are created.
4114 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
4115 check.
4116 * tests/autotest.at (Empty test, Empty check): New test to check it.
4118 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
4119 from gcc.
4121 2006-04-10 Stepan Kasal <kasal@ucw.cz>
4123 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
4124 the files if a problem appears. Make the empty *.at files
4125 read-only, too. Proposed by Ralf Wildenhues.
4127 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4129 * config/Makefile.am: Add comment to force updated Makefile.in.
4131 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
4132 space only patch to this file, this patch causes the Makefile.in
4133 files that include freeze.mk to be updated, and thus have a
4134 newer time stamp again, which in turn makes a pristine CVS
4135 checkout have correct time stamps.
4137 * Makefile.maint (cvs-sv): New macro, to be used..
4138 (config.guess-url_prefix, config.sub-url_prefix)
4139 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
4140 point to CVS text checkout of Gnulib files.
4141 (copyright-check): Bump current year.
4142 (announcement): Do not hard-wire `./announce-gen'.
4143 (cvs-update): Propagate failures of `cvs' and `move-if-change'
4144 correctly.
4145 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
4146 `chmod +x'.
4147 (wget_files): Update config.guess, config.sub, texinfo.tex by
4148 `wget-update', now that their URLs work again.
4150 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4152 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
4153 Problem noted by Paul D. Smith.
4155 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4157 * doc/autoconf.texi: Remove unused words from word list.
4158 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
4159 .x-sc_trailing_space: New files.
4161 * doc/standards.texi: Sync from gnulib.
4163 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
4164 `LIBOBJDIR' as experimental.
4166 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
4167 with a target directory; it's internally implemented as `cp'
4168 anyway, but since Autoconf advertises the possibility to use
4169 a target directory when LN_S is `ln -s', we need to find out.
4170 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
4171 analyzed by Keith Marshall <keith.marshall@total.com>.
4173 * THANKS: Update.
4175 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4177 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
4178 confdefs.h as-is. In general, if it has backslash-newline or the
4179 like, then it doesn't work either to sort or to remove empty
4180 lines.
4182 2006-04-09 Stepan Kasal <kasal@ucw.cz>
4184 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
4186 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
4188 * lib/autom4te.in (Automake-preselections): Preselect
4189 _AM_SUBST_NOTMAKE.
4191 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
4193 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
4194 apostrophe within a single-quoted string, as this is the usual
4195 tradition and is easier to read than '"'"'. Don't rely on the
4196 shell treating "$/" like '$/'. Use a more-consistent indenting
4197 style for the trap.
4199 2006-04-09 Eric Blake <ebb9@byu.net>
4201 * tests/autotest.at (Backquote command substitution),
4202 (Multiline backquote command substitution): Remove mistaken
4203 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
4204 applied...
4205 (Parenthetical command substitution, Multiline parenthetical
4206 command substitution): here.
4208 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

4238 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
4239 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
4240 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
4241 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
4242 (C Compiler): Move AC_C_LONG_DOUBLE to ...
4243 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
4244 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.

4265 New macros.
4267 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
4268 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
4270 2006-04-08 Stepan Kasal <kasal@ucw.cz>
4272 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
4273 of the warning introduced by the 2001-08-28 change.

4281 that contains braces.
4283 2006-04-07 Stepan Kasal <kasal@ucw.cz>
4285 Revert the patch from 2006-04-01 and only improve
4286 _AS_DETECT_BETTER_SHELL:
4288 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
4289 skip nonexistent directories.
4290 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
4291 only shell candidates which exist.
4292 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
4293 * lib/autotest/general.m4 (AT_INIT): No need to give three
4294 parameters to _AS_PATH_WALK.
4296 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
4297 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4299 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
4300 distinguish m4sugar macros.
4301 * tests/tools.at (autoupdating with aclocal and m4_include):
4302 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
4303 test case by Noah Misch <noah@cs.caltech.edu>.
4305 2006-04-07 Stepan Kasal <kasal@ucw.cz>
4307 Revert my change from 2006-03-17, in other words:
4308 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
4309 and DUALCASE=1.
4310 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
4311 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
4312 it is set.
4314 2006-04-07 Eric Blake <ebb9@byu.net>
4316 * doc/autoconf.texi (Programming in M4sh): Document that
4317 AS_MKDIR_P exits the script on failure.
4318 * lib/autotest/general.m4: Remove redundant AS_ERROR.
4320 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4322 * config/elisp-comp, config/install-sh, config/mdate-sh,
4323 config/missing, config/mkinstalldirs: Sync from Automake.
4325 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
4326 from Automake.
4328 * doc/make-stds.texi: Sync from gnulib.

4332 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4333 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced

4337 Eric Blake <ebb9@byu.net>,
4338 Paul Eggert <eggert@cs.ucla.edu>,
4339 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4341 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
4342 whether `set' quotes correctly: redirect stderr of the tested
4343 `set', and use a subshell, for Ultrix; use `sed' instead of
4344 `grep' for zsh `set' which may write binary output; match only
4345 at the beginning of a line, to avoid false positives.
4346 In order to avoid false positives by unrelated variables with
4347 multiline content, put the dump algorithm in a subshell and
4348 unset all variables containing newlines (except some which are
4349 special to the shell). Warn about cache variables that are
4350 unset.
4352 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4354 * config/config.guess, config/config.sub, config/texinfo.tex:

4362 (AC_ARG_VAR): Do test this now.
4363 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
4364 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
4365 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
4366 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
4368 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
4369 shell issue with double-quoted command substitutions of native
4370 commands.
4371 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
4372 Marshall.
4374 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

4382 (sc_tight_scope): Do not fail for non-existing `src' directory.
4383 (sc_changelog): Skip the Copyright footer.
4384 * lib/autoconf/lang.m4: Remove trailing space.
4386 * lib/autoconf/status.m4: More replacements to
4387 <tab><space> where this makes sense.
4389 2006-04-06 Stepan Kasal <kasal@ucw.cz>
4391 * tests/Makefile.am (maintainer-check-posix):
4392 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
4394 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
4395 ac_config_<foo>s again, sometimes normalized, sometimes not.
4396 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
4397 (AC_CONFIG_COMMANDS): Do not do so here.
4398 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
4399 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
4400 2005-07-25 rewrite. Noticed by Noah Misch.
4402 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
4403 _AC_PRESERVE_HELP_ORDER, ...
4404 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
4406 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
4407 inside m4_expand_once; it is redundant.
4409 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
4410 for --help from Cygnus `configure.'
4412 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
4414 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
4415 on a patch proposed by Ralf Wildenhues.
4417 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
4419 * lib/autoconf/status.m4: Replace <space>''<tab> with
4420 <tab><space> where this makes sense.
4422 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
4423 Noah Misch <noah@cs.caltech.edu>
4425 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
4426 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
4427 * doc/autoconf.texi (Help Formatting): New node.
4428 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
4430 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4432 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
4433 lib/autoconf/specific.m4, lib/autoconf/status.m4,
4434 lib/autoconf/types.m4, lib/autotest/general.m4,
4435 tests/mktests.sh, tests/torture.at: White space cleanup:
4436 remove some SPACE before TAB, or add quoting ('' or @&t@).
4438 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
4440 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
4442 2006-04-05 Eric Blake <ebb9@byu.net>
4444 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
4445 empty test suite works.
4446 * tests/autotest.at (Empty test suite): Remove xfail.
4448 2006-04-05 Noah Misch <noah@cs.caltech.edu>
4450 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
4451 TAGS to ac_config_<foo>s.
4452 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
4453 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
4454 normalizing it, consistent it with previous releases.
4455 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
4457 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
4459 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
4460 Use simplified args that Eric Blake originally suggested.
4462 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
4464 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
4465 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
4466 Use 'comm' rather than N instances of grep; this also fixes a bug
4467 whereby substrings were incorrectly matched, causing us to not
4468 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
4469 (exclude_list): Exclude empty macros.
4470 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
4472 Use awk rather than grep -E or egrep, to avoid
4473 portability problems with regular expressions containing newlines.

4475 Switch from grep to awk syntax.
4476 (ac_exclude_script): Renamed from ac_exclude_egrep.
4477 (au_exclude_script): Renamed from au_exclude_egrep.
4479 2006-04-04 Noah Misch <noah@cs.caltech.edu>
4481 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
4482 a subdirectory subject to Cygnus `configure'.
4483 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
4485 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
4486 report request when we have no AC_PACKAGE_BUGREPORT.
4488 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4490 * THANKS: Update.
4492 * tests/mktests.sh: Update copyright year in the header of the
4493 generated files.
4495 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
4496 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
4497 typedef'ed restricted pointer, to catch a compiler bug on
4498 HP-UX 11.x, and fix warnings so it passes with -Werror.
4499 (_AC_PROG_CC_C99): Likewise.
4500 Reported by Albert Chin <china@thewrittenword.com>.

4505 * bin/autoscan.in (subdirs): New global.
4506 (scan_file): Prune directories with configure{,.{ac,in,gnu}}.
4507 (output): Emit AC_CONFIG_SUBDIRS as needed.
4508 * tests/autoscan.at (autoscan): Remove XFAIL.
4510 2006-04-03 Noah Misch <noah@cs.caltech.edu>
4512 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use AC_MSG_NOTICE.
4514 2006-04-03 Eric Blake <ebb9@byu.net>
4516 * THANKS: Add myself.
4518 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4520 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
4521 to log, point to testsuite output tree.
4523 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
4525 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
4526 * doc/autoconf.texi (Function Portability): Mention that C++
4527 has trouble with 'exit'.
4528 (Guidelines): Test programs shouldn't use 'exit'.
4529 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
4530 Remove; all uses removed.
4531 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):
4532 Return from 'main' instead of calling 'exit'.
4533 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_CLOSEDIR_VOID):

4537 (AC_FUNC_SETPGRP, _AC_FUNC_STAT, AC_FUNC_STRTOD, AC_FUNC_STRERROR_R):
4538 (AC_FUNC_STRNLEN, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4539 (_AC_FUNC_FORK, _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4540 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Likewise.
4541 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4542 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.

4545 2006-04-02 Pavel Roskin <proski@gnu.org>
4547 * doc/autoconf.texi (AC_PATH_X): Update per 2005-08-26 change.
4549 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4551 Clean up _AC_COMPILER_EXEEXT* macros.
4553 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4554 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4555 ac_file to the name of the default output file and call
4556 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4557 initial `rm' of the candidate files...
4558 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4559 the same list in subsequent `rm' calls, and for the temporary
4560 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4561 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4562 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4563 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4564 no longer needed) by libtool. Make it a cache check.

5343 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
5344 by the function rather than ignoring it.
5345 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
5346 comparing its address. Intel's interprocedural optimization was
5347 outsmarting the old heuristic. Problem reported by

5365 Stepan Kasal <kasal@ucw.cz>
5367 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
5368 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
5369 make its content writable before removing it. Remove an errorneous
5370 comment from the end, where the logs of the failed tests are copied
5371 to the main log file.
5373 2005-09-27 Stepan Kasal <kasal@ucw.cz>

5380 problems if the testsuite were running too fast.
5382 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5384 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h

5396 suggested by Ben Elliston. Handle weird characters correctly.
5398 2005-09-06 Stepan Kasal <kasal@ucw.cz>
5400 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
5401 calls, so that the final expansion of this macro is shorter.
5402 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
5403 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
5404 the cleanup there. Use AS_VAR_* macros, to be more general.
5405 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
5407 * lib/autoconf/general.m4: Use AS_IF where appropriate.
5409 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

5427 2005-08-26 Stepan Kasal <kasal@ucw.cz>
5429 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
5430 in the example. Reported by Bruno Haible.
5431 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
5432 "if $undefined_var;" succeeds with my shell.
5434 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
5435 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
5436 but change the m4_divert_text to m4_divert_once.

5451 Stepan Kasal <kasal@ucw.cz>
5453 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
5454 first header appears, define AH_HEADER.
5455 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
5456 Update limitations about when to call AC_CONFIG_HEADERS.
5457 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
5458 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
5459 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
5460 ``Configuration Actions''; fix their index entries.
5462 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
5463 options correctly. Process N-M as M-N if M is smaller than N.
5464 Process ranges correctly so that N-N will run only N.
5465 Sort and uniquify the tests that will be run. If there is more
5466 than one test, reinsert the banners for the tests.

5472 before passing the macro name to AH_TEMPLATE.
5474 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status

5493 Prepend to LIBS, not append, in examples.
5495 2005-08-16 Stepan Kasal <kasal@ucw.cz>
5497 When building in place, set srcdir="."; suggested by Tim Van Holder.
5499 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
5500 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
5501 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
5502 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
5503 does not mean "no --srcdir option".
5505 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5507 * tests/autoscan.at (autoscan): New file.
5508 * tests/suite.at: Use it.
5509 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
5510 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
5512 * tests/autotest.at (Keywords): Test keywords combinations.
5514 2005-08-12 Stepan Kasal <kasal@ucw.cz>
5516 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
5517 add "2>&1"; gzip 1.2.4 prints help on stderr.
5519 2005-07-27 Stepan Kasal <kasal@ucw.cz>
5521 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
5522 was pushdef'ed twice while popped only once. Push it only once.
5523 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
5525 2005-07-26 Stepan Kasal <kasal@ucw.cz>
5527 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
5528 prefixed by mere "===", not "configure: === ".
5530 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
5532 * Makefile.maint: Update from Bison.
5534 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
5535 "<tab>" in comment, so that the point is understandable.
5537 2005-07-25 Stepan Kasal <kasal@ucw.cz>
5539 Rewrite substantial part of lib/autoconf/status.m4.
5540 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
5541 and CONFIG_COMMANDS are not processed in four separate loops.
5542 Instead, there is one main loop. This alows that the common code
5543 is expanded only once, thus config.status (and configure) is smaller.
5545 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
5546 the AC_LIST_FILES and cousins macros are no longer used.
5548 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
5549 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
5550 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
5551 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
5552 contain the initialization, nor the for loop, nor the associated
5553 commands; all these go to ...
5554 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
5555 _AC_OUTPUT_CONFIG_STATUS.
5556 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
5557 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
5558 (_AC_OUTPUT_FILE): The creation of the sed script ...
5559 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
5560 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
5561 _AC_OUTPUT_MAIN_LOOP.
5562 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
5563 _AC_CONFIG_COMMANDS): Use ...
5564 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
5565 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
5566 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
5567 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
5568 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
5569 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
5570 ... new macros.
5571 (_AC_CONFIG_UNIQUE): Update.
5572 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
5573 Replaced by this ...
5574 (_AC_LIST_TAGS): ... new common macro.
5575 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
5576 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
5577 (_AC_LIST_TAG_COMMANDS): ... new common macro.
5578 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
5579 this didn't belong to the `config commands' section.
5580 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
5581 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
5582 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
5583 to the `config commands' section either.
5584 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
5585 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
5587 ... and many changes to the comments nearby.
5589 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
5590 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
5591 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5592 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
5593 (#define header templates): The comment at the top of the generated
5594 header now includes the name(s) of the source file(s).
5596 Several unrelated small changes:
5598 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
5599 parameter to AC_DIAGNOSE.
5600 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
5601 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
5602 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
5603 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
5604 with AU::AC_OUTPUT.
5605 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
5606 in AC_OUTPUT doesn't double-quote it either.
5607 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
5608 parameters.
5610 2005-07-10 Stepan Kasal <kasal@ucw.cz>
5612 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
5613 versions of Portland Group compiler produce single- and double-quoted
5614 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
5615 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
5617 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
5619 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
5620 This is a corrected version of yesterday's patch.
5622 2005-07-07 Stepan Kasal <kasal@ucw.cz>
5624 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
5625 path, too; insert a "===" to emphasize the line.
5627 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
5628 ac_cv_build_alias to ac_build_alias.
5629 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
5631 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
5632 change eliminates it. Problem reported by Alexandre Duret-Lutz.
5633 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
5634 (AC_ARG_VAR): ... here.
5635 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
5636 target_alias.
5638 Keep a list of all precious variables and process them with one simple
5639 for loop, instead of expanding all commands, or, OTOH, complicated
5640 processing of output of "set".
5641 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
5642 variable names in new macro...
5643 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
5644 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
5645 a loop to assign all ac_env_* and ac_cv_env_* variables.
5646 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
5647 to INIT_PREPARE.
5648 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
5649 its value to shell variable ac_precious_vars and call
5650 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
5651 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
5652 _AC_ARG_VAR_VALIDATE.
5654 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
5655 and the AC_SUBSTs ...
5656 (AC_INIT): ... here.
5658 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
5659 the ac_subst_files section in config.log.
5661 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.

5670 Fix problems reported by Nicolas Joly.
5671 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
5672 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
5673 They are generated by the Tru64 v5.1B shell.
5675 2005-07-05 Stepan Kasal <kasal@ucw.cz>
5677 Fix my changes from 2005-07-01; reported by Noah Misch.
5678 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
5679 description, the macro now accepts only a single tag.
5680 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
5682 Fix cases when the varsions of Autoconf and Autotest don't match.
5683 Reported by Noah Misch.
5684 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
5685 at_top_builddir, for compatibility with older autotest.
5686 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
5687 is not set, use at_top_builddir, for compatibility with older
5688 versions of autoconf.
5690 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
5692 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
5693 Problem reported by Patrick Welche.
5695 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
5697 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
5698 sed substitution command, so that we allow | in program prefixes
5699 and program suffixes. (& is a problem anyway; we're not fixing
5700 that here.)
5701 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
5702 configure_input, top_builddir, srcdir, etc.
5703 * lib/autotest/general.m4 (AT_INIT): Likewise, for
5704 PATH_SEPARATOR in AUTOTEST_PATH.
5706 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
5708 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
5709 for loop over config.site files using `set', to allow
5710 directory names containing IFS characters.

5714 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
5715 directories with weird names. Apparently some people like living
5716 on the edge. However, improve the test that "pwd" actually does
5717 report a name for the working directory.

5720 2005-07-01 Stepan Kasal <kasal@ucw.cz>

5733 (Generic Functions): Mention the Gnulib project.
5734 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
5736 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
5737 document to output the default config_* lists to config.status.
5738 Don't recognize option --file, if the functionality is not there.
5739 Likewise for --header; moreover, recognize --he and --h as shortcuts
5740 for --help in that case.
5742 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
5743 matches the order of execution. No code changed.

5764 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
5765 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
5766 (AC_SUBST): Call it.
5767 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
5768 the directory specific variables; but don't call it for configure_input.
5770 2005-06-28 Derek Price <derek@ximbiot.com>
5772 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
5773 addition.
5775 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
5777 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
5778 directory have inherent problems with special characters like spaces,
5779 due to limitations in Make syntax. Problem reported by Alexandre
5780 Duret-Lutz.
5781 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
5782 Also, fix Tru64 porting problem with shell patterns,

5793 Fix some more shell quoting problems. Prompted by a bug report
5794 from Justace Clutter.
5795 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
5796 variable into diagnostic. Make the diagnostic an error, not a warning,
5797 because we really don't support spaces and suchlike in dir names.
5798 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
5799 Don't worry about backslashes in srcdir; it can't happen now.
5800 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
5801 Simplify ac_optarg handling.
5802 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

5810 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
5812 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
5813 that '\|' is not allowed in BREs; recommend using newline separated
5814 list of patterns instead of multiple -e options.
5816 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
5818 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

5824 2005-06-21 Stepan Kasal <kasal@ucw.cz>
5826 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
5827 b, t, r, w commands require single space, while : cannot have any.
5828 (Special Shell Variables): Fix sed code this in the example.
5829 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
5830 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
5832 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
5833 expand to the empty list. Don't use two pairs of m4_changequote,
5834 it's not necessary.
5836 2005-06-20 Derek Price <derek@ximbiot.com>
5838 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
5840 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
5842 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
5843 * doc/autoconf.texi:
5844 Don't mention Solaris versions so much, if a
5845 problem is common to all extant versions of Solaris. Say "SunOS
5846 4" instead of "SunOS" for SunOS 4.
5847 (awk): Mention more of the limitations of traditional Awk.
5848 (cat): Don't talk about cat -v.
5850 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
5852 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
5853 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
5854 but the implementation is entirely different and is designed
5855 to be compatible with glibc strverscmp.
5856 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
5858 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
5859 on Mac OS X 10.4 reported by Peter O'Gorman in:
5860 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
5861 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
5862 Use shell builtins rather than 'expr', to work around expr bug.
5864 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
5866 * doc/autoconf.texi: "filesystem" -> "file system".
5867 "behaviour" -> "behavior".
5868 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
5869 * lib/autoconf/general.m4: Omit blank after ":" sed command,
5870 as per POSIX.
5871 * lib/m4sugar/m4sh.m4: Likewise.

5873 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
5875 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
5876 (.x.1): Ignore the time stamp in the .TH line when deciding whether
5877 to update the man page. That way, we don't have to check in new
5878 man pages every month.
5880 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
5881 quotes and backslashes. Patch from Derek Price.
5883 2005-06-10 Derek Price <derek@ximbiot.com>
5885 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &
5886 AS_TR_SH.
5888 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
5890 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
5891 -u, since it outputs chatter if the input files are the same.
5892 Problem reported by Ralf Menzel.
5894 2005-06-08 Derek Price <derek@ximbiot.com>
5896 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
5897 renaming them since they are about to be redefined anyhow.
5899 2005-06-08 Derek Price <derek@ximbiot.com>
5901 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
5902 redefined M4 macros to this node. Document m4_include & m4_sinclude.
5903 Move m4_undefine to alphabetical order.
5905 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
5907 * README: Recommend GNU M4 1.4.3 or later.
5908 * doc/autoconf.texi (Introduction): Likewise.
5909 Reword to avoid some formatting glitches.
5910 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
5911 Clarify explanation of HP compiler bug.
5912 Redo example output tp match current CVS snapshot.
5913 Use @example.org in email addresses when the examples
5914 might get inadvertently cut-and-pasted into user code.
5915 Remove example of autom4te usage that doesn't seem to work now.
5916 Use modern AC_INIT (except when the example is meant to be
5917 shown with Autoconf 2.13).
5918 Update ksh info for Solaris 9 and later.
5919 KB -> kB.
5920 Modernize description of Automake versions a bit.
5921 Don't claim a future version of Autoconf is near.
5922 * doc/install.texi: Reword to avoid some formatting glitches.
5924 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5926 * doc/autoconf.texi: Add [] to examples, so that the manual
5927 follows its own advice about quoting better.
5928 Reword to avoid some formatting glitches.
5929 * doc/installt.exi: Reword to avoid some formatting glitches.
5931 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
5932 Tru64 ksh pattern matching bug. Reported against Libtool by
5933 Albert Chin <libtool@mlists.thewrittenword.com> and
5934 Nicolas Joly <njoly@pasteur.fr>.
5936 2005-06-06 Stepan Kasal <kasal@ucw.cz>
5938 m4_cdr of one-member list was [[]] (one-member list containing an
5939 empty string) instead of [] (an empty list. Callers were skewed to
5940 match this misbehaviour. As a consequence of this:
5941 - m4_foreach([x], [], [foo]) expanded to `foo', while
5942 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
5943 This bug has been fixed:
5945 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
5946 expand to an empty string; print error msg if called without
5947 an argument list.
5948 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
5949 misbehaviour; handle [] and [[]] correctly.
5951 2005-06-06 Stepan Kasal <kasal@ucw.cz>
5953 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
5954 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
5955 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
5957 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
5959 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
5960 swallow records with more than 99 fields.
5961 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
5962 parse the long line.
5964 2005-06-04 Stepan Kasal <kasal@ucw.cz>
5966 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
5967 swallow literals longer than 399. Reported by Ralf Wildenhues.
5968 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
5969 to workaround this limitation.
5971 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
5973 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
5974 to gfortran, and make these the first two compiler names
5975 checked (following the general autoconf preference for gcc).
5977 2005-06-03 Stepan Kasal <kasal@ucw.cz>
5979 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
5980 (DISTCLEANFILES): Remove $(check_SCRIPTS).
5981 (testsuite): Make sure autotest.m4f is up-to-date before using it.
5983 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
5985 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
5986 expression of unbounded size when processing the --list
5987 option. This runs afoul of a limit of 399 bytes per regular
5988 expression on AIX. Problem reported by Ralf Wildenhues.
5990 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
5992 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
5993 * doc/autoconf.texi (Particular Headers): Reword example
5994 for multiline stdbool replacement.
5995 (Setting Output Variables): Reword text a bit. Don't
5996 give all the details about |#_!!_#|.
5997 Reword description of line replacement.
5999 2005-05-31 Dan Manthey <dan_manthey@partech.com>
6001 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
6002 now contain newlines, and substituted files must be referenced on
6003 a line alone; the sed scripts to substitute them are now very
6004 different.
6005 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
6006 commands can be put in a sed script portably.
6007 * doc/autoconf.texi (Setting Output Variables): Document above
6008 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
6009 use of multiline substitution.
6010 * tests/torture.at: No longer expect substitution of newline to fail.
6012 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
6014 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
6015 From Ralf Menzel (trivial change).
6017 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
6019 * tests/local.at: Don't attempt to check for negated character
6020 classes in shell scripts. The test was too brittle.
6022 2005-05-25 Stepan Kasal <kasal@ucw.cz>
6024 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
6025 * doc/autoconf.texi (Limitations of Builtins): Document this
6026 limitation.
6028 2005-05-24 Stepan Kasal <kasal@ucw.cz>
6030 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
6031 common code; used in many places in the tree.
6032 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
6033 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
6035 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
6037 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
6038 messages when ac_unique_file is not found.
6039 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
6040 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
6041 commands, for consistency with AC_MSG_ERROR and such.
6043 * bin/autoconf.as: Make more use of "shift 2" in option processing.
6045 * bin/Makefile.am: Merge the two rules for creating scripts.
6047 2005-05-23 Stepan Kasal <kasal@ucw.cz>
6049 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
6050 obsolete; it was never documented.
6051 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
6053 2005-05-20 Stepan Kasal <kasal@ucw.cz>
6055 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
6056 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
6057 (ac_top_builddir): ... this ...
6058 (ac_top_build_prefix): ... to this; the old name is also kept, for
6059 backward compatibility.
6060 (ac_top_builddir_sub): New variable, without the trailing slash,
6061 always nonempty.
6062 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
6063 * doc/autoconf.texi (Configuration Actions): Rename
6064 ac_top_builddir to ac_top_build_prefix.
6065 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
6066 at_top_builddir to at_top_build_prefix.
6067 * lib/autotest/general.m4 (AT_INIT): Likewise.
6069 2005-05-20 Stepan Kasal <kasal@ucw.cz>
6071 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
6072 of confdefs.h .
6074 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6076 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
6077 argument to m4_foreach. I guess it was necessary in the past,
6078 but I think it's a no-op now.
6080 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6082 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
6083 ``cat <<_ACEOF'' commands to one.
6084 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
6085 * lib/autoconf/status.m4: On various places, use expr instead of
6086 ``echo|sed.''
6087 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
6088 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
6089 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
6090 a range.
6091 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
6092 the wrong patterns between ``case'' and ``esac.'' The previous
6093 code had false positives.
6095 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
6097 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
6098 as on 2005-05-02.
6099 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
6100 Mention LIBOBJDIR.

6140 2005-05-13 Stepan Kasal <kasal@ucw.cz>
6142 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
6143 check.
6144 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
6145 enough arguments, similarly as in m4_bpatsubsts.
6147 2005-05-12 Stepan Kasal <kasal@ucw.cz>
6149 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
6150 of absolute paths.
6152 2005-05-11 Stepan Kasal <kasal@ucw.cz>
6154 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
6155 for absolute directory names in one loop.
6156 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
6157 abbreviations of --version and --debug.
6159 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
6161 * doc/autoconf.texi (Autoconf Language): Be more precise about
6162 quoting rules. Problems noted by Stepan Kasal.
6163 Also, throughout this document, be more careful about white space.
6164 "blank", "white space", and "space" all have different meanings
6165 and we should be careful to say what we mean.
6167 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
6169 Fix C++ related problems reported by Werner Lemberg.
6170 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
6171 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
6172 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
6173 avoid problems with C++ and throw.
6174 * tests/compile.at: .cpp, not .cc.
6176 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
6178 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6180 * doc/autoconf.texi (Generic Functions): Typos.
6182 2005-05-02 Gary V. Vaughan <gary@gnu.org>
6184 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
6185 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
6186 set by latest automake.
6188 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
6190 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
6191 outputs 0 on GNU/Linux these days.
6193 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
6195 * doc/autoconf.texi (Autoconf Language): Add more description
6196 about quoting heuristics.
6197 (Limitations of Builtins): Describe "set -" problems.
6199 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6201 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
6202 not newline.
6204 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
6205 by AC_DEFINE; it was a mistake.
6206 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
6208 2005-04-25 Stepan Kasal <kasal@ucw.cz>
6210 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
6212 2005-04-22 Stepan Kasal <kasal@ucw.cz>
6214 * doc/autoconf.texi (External Software): Quadrigraphs are not
6215 processed correctly in AS_HELP_STRING; avoid this in the examples.
6216 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
6217 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
6218 comment and reduce m4_default([foo], []) to [foo].
6219 (m4_strip): Update the explanation.
6221 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
6223 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
6224 Remove core.conftest.* too; it's generated by Tru64 5.1.
6225 Problem reported by Jennis Pruett.
6226 * lib/autoconf/functions.m4
6227 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
6228 Don't bother to remove core files; AC_RUN_IFELSE should do that
6229 for you.
6231 2005-04-19 Stepan Kasal <kasal@ucw.cz>
6233 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
6235 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
6237 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
6238 Report from Horst Wente.
6240 2005-04-15 Stepan Kasal <kasal@ucw.cz>
6242 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
6243 the comment.
6245 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
6247 * doc/autoconf.texi (External Software, Package Options): Add
6248 examples showing how to implement --with-* and --enable-* options.
6250 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
6252 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
6253 as well as configure.in. Problem reported by Gregorio Guidi.
6255 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
6257 * doc/autoconf.texi (Particular Functions): Use gnulib's current
6258 pattern for alloca snippet.
6260 2005-04-04 Stepan Kasal <kasal@ucw.cz>
6262 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
6264 2005-04-01 Stepan Kasal <kasal@ucw.cz>

6268 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
6270 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
6271 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
6273 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6275 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
6276 Merge `-z option' as well for the benefit of Solaris link flags. Pass
6277 whole-archive (-zallextract, -zdefaultextract) options in the hope of
6278 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
6279 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
6281 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
6283 * NEWS: The configure command now warns you if you attempt to use
6284 a directory whose name contains a special character like space,
6285 newline, or "\".
6286 * doc/autoconf.texi (Installation Directory Variables): Allow
6287 "," in file names. Do not use \@; it's not a portable regexp.
6288 * bin/Makefile.am (edit): Likewise.
6289 * lib/Makefile.am (edit): Likewise.
6290 * tests/Makefile.am (edit): Likewise.
6291 * tests/semantics.at: Likewise.
6292 * tests/torture.at: Likewise.
6293 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
6294 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
6295 * doc/autoconf.texi (File System Conventions): Warn about
6296 unportable file names.
6297 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
6298 (AC_INIT): Use it.
6299 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
6300 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
6301 ac_pwd, and quote srcdir.
6302 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
6304 * doc/autoconf.texi: Fix some systematic formatting problems.
6305 ".)" needs a following @: if not at the end of a sentence, and
6306 similarly for "!)". "etc." should be preceded by a comma.
6307 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
6309 2005-03-22 Bruno Haible <bruno@clisp.org>
6311 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
6312 argument is often called 'build-aux'.
6314 2005-03-07 Stepan Kasal <kasal@ucw.cz>
6316 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
6317 macro AC_TRY_LINK is obsolete.
6318 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
6319 `AC_CONFIG_FILES'.
6321 2005-02-24 Stepan Kasal <kasal@ucw.cz>
6323 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
6324 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
6325 from a Common Lisp's `cl'.
6326 (AC_PROG_CXX): Behave according to the documentation: don't
6327 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
6328 make the variable CCC precious; use `cl.exe', not `cl'.
6330 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6331 Alexandre Duret-Lutz <adl@gnu.org>
6333 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
6334 /dev/null, as "configure" shouldn't read stdin, and this insulates
6335 us from problems (e.g., when testing for "cl"). Also, do this
6336 redirection before invoking "hostname" or "uname", and keep the
6337 original input stream available via...
6338 (AS_ORIGINAL_STDIN_FD): ... this new macro.
6339 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
6340 bother with "</dev/null" since it's now done at the top of
6341 'configure'.
6342 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
6343 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6344 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
6345 * doc/autoconf.texi (File Descriptor Macros): New section.
6346 (Printing Messages): Mention it.
6347 * tests/base.at (Input/Output): New test.
6349 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6351 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
6352 newline if neither \c nor -n work, as that would output two
6353 newlines. Prefer -n to \c. Reported by Stepan Kasal.
6355 2005-02-12 Stepan Kasal <kasal@ucw.cz>
6357 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
6358 This causes that any required macros inside will get before the if.
6359 * doc/autoconf.texi (autom4te.cache): A typo.
6361 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
6363 Undo previous change, except keep the change to
6364 lib/autoconf/programs.m4 that replaced grep with shell
6365 pattern-matching. This is because net-snmp configure reads stdin.
6366 Reported by Noah Misch.
6368 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
6370 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
6371 from /dev/null, as "configure" shouldn't read stdin, and this
6372 insulates us from problems (e.g., when testing for "cl").
6373 Suggested by Alexandre Duret-Lutz. Also, do this redirection
6374 before invoking "hostname" or "uname".
6375 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6376 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
6377 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
6378 "</dev/null" since it's now done at the top of 'configure'.
6379 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6380 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
6381 Also, replace grep with shell pattern-matching, to save a process.
6383 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
6385 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6386 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
6387 avoid thinking that Allegro Common Lisp's "cl" command is a C++
6388 compiler.
6390 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
6392 * doc/autoconf.texi (Limitations of Usual Tools): Document that

6486 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
6488 Try not to generated lines of unlimited length, as POSIX places a
6489 2047-byte limit on line length of portable text files.
6490 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
6491 Use newline as a separator, not space.

6494 space.

6549 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
6550 Update the long comment explaining it.
6552 m4_require no longer writes an ``is required by'' line to the
6553 execution stack. It contains only one bit of non-redundant
6554 information: that the macro was required, not called. And even
6555 this bit is useless in most situations: have you ever met a macro
6556 which both calls and requires the same macro?
6558 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
6559 (_m4_defun_pro_outer): ... only via this macro, for the outermost

6566 (_m4_require_call): Use it.
6567 * tests/m4sugar.at (m4_require): Expect output without the
6568 ``is required by'' messages.
6570 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
6572 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
6573 rather than x for expr.
6575 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
6576 this is safe.
6577 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
6578 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

6590 from masters, so that FileUtils.pm's update_file provide --force
6591 support.
6592 * bin/autoheader.in: Pass $force to update_file so that
6593 config.h.in is always recreated when --force.

6599 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
6601 * doc/autoconf.texi (Limitations of Builtins): Clarify that
6602 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
6604 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
6606 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
6607 Warn about newline stripping in `` and $(). Update Solaris
6608 version to 9.
6609 (Limitations of Builtins): Use expr "X...", not expr "x...", as
6610 X insulates us from future changes to Posix.
6611 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
6612 stripping.
6614 2005-01-19 Stepan Kasal <kasal@ucw.cz>

6632 ulongval to be static, to avoid unwanted GCC warning. Problem
6633 reported by Michael Jennings via Daniel Reed; see
6634 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
6636 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
6638 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

6660 (_m4_divert_n_stack): New macro; the expansion is
6661 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
6662 otherwise.
6663 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
6664 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
6665 stored in _m4_divert_diversion or _m4_divert_dump.
6666 (m4_divert_pop): When the parameter is given, compare the symbolic
6667 name with the last diversion pushed on the stack. Previously, the
6668 current diversion was compared with the numeric value of the
6669 diversion given as the parameter.
6670 (m4_require): If the macro hasn't been expanded yet, call ...
6671 (_m4_require_call): this new macro.

6704 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

6757 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
6758 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

6885 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

6950 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>

6953 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
6954 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.

6976 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
6978 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
6979 "char c = '\200';" rather than "char c = 0x80;" as the
6980 latter doesn't conform to the strict C standard due to
6981 overflow on signed char hosts.
6983 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
6984 to -qlanglvl=ansi. We don't want to disable extensions.

6988 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.

7084 Problem reported by Stepan Kasal.
7086 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>

7097 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
7098 "/usr/include", clear ac_x_includes instead of leaving it as "no"
7099 (trivial change). Problem and patch reported by Andrew Church in:
7100 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
7102 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

7107 Also, fix some minor spacing and punctuation bugs.

7132 Remove ansi2knr.c; nobody uses it.
7133 (ansi2knr.c-url_prefix): Remove.
7134 (cvs-update): Fix test for failure. I don't know why it ever
7135 worked...
7137 * doc/autoconf.texi: Update URLs, some of which went stale.
7138 Use @uref rather than @href.
7140 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure

7143 * config/config.guess, config/config.sub, config/elisp-comp,
7144 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
7145 doc/fdl.texi, doc/standards.texi: Sync with master copy.
7147 * NEWS, TODO, configure.ac, bin/autoscan.in,
7148 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
7149 doc/install.texi, lib/Autom4te/Configure_ac.pm,

7153 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
7154 tests/tools.at, tests/torture.at:
7155 Use "file name" rather than "filename" or "path",
7156 to be consistent with the terminology of the GNU coding standards.
7158 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
7160 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),

7166 This isn't a complete fix but it's an improvement.
7168 * bin/autoconf.as (autom4te_options): New var.
7169 Use it instead of appending to AUTOM4TE, so that we can allow
7170 spaces in the build directory's absolute name.
7171 * bin/autoheader.in ($autoconf): Allow spaces in file names.
7172 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

7193 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
7194 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
7195 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
7197 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>

7200 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
7201 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
7202 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
7203 * lib/autom4te.in (Automake-preselections): Preselect
7204 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
7206 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
7208 * lib/autom4te.in (Automake-preselections): Preselect
7209 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
7210 trace them.
7212 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
7214 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for

7222 with pdksh, too. Problem reported by Patrick Welche via
7223 Gary V. Vaughan.
7224 * doc/autoconf.texi (Shellology): Note that set -o posix is
7225 useful for pkdsh, too.
7227 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
7229 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
7230 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
7231 Don't fail if ENV or BASH_ENV is readonly.
7232 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,

7243 * doc/autoconf.texi (File System Conventions): Warn about
7244 names like "aux". Problem reported by Eric Blake.
7246 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
7247 by zero instead of array size, so that we can use any arithmetic
7248 constant expression (instead of requiring an integer constant
7249 expression). This allows us to test expressions like DBL_MAX <
7250 LDBL_MAX, which didn't conform to the C standard using the old
7251 method.
7252 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
7253 now that we can do floating-point tests at compile time.
7255 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
7257 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
7258 and LDBL_EPSILON, as the resulting expression isn't an
7259 integer constant expression and violates the C standard.
7260 Problem reported by Nelson H. F. Beebe. Also, check
7261 for "L" suffix, and check that long double doesn't have
7262 worse range or precision than double, that mixed-mode
7263 arithmetic doesn't generate a diagnostic, that double
7264 constants fit in long double.
7266 2004-06-03 Kevin Ryde <user42@zip.com.au>
7268 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
7269 malloc(0) and realloc(NULL,size).
7271 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
7272 Bob Proulx.
7274 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>

7282 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
7283 can be rewritten using if-then-else. Suggested by Bruno Haible.

7293 change). Patch reported by Ralf Wildenhues in
7294 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
7296 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
7297 function F exists if the compiler and linker let you compile an
7298 expression like (F != 0). Recent versions of GCC optimize away
7299 the reference to F in that case, since every function address must
7300 be nonzero, so the link succeeds even if F does not exist.
7301 Problem reported by Manu in
7302 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
7304 * doc/autoconf.texi (Systemology): Standardize on the spelling of
7305 "Unix". Many uses changed.
7306 (Limitations of Builtins): Explain better why the ! command isn't
7307 portable.
7309 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
7311 * lib/autom4te.in (Automake-preselections): Preselect
7312 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
7314 2004-05-19 Kevin Ryde <user42@zip.com.au>
7316 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
7317 referencing AC_FUNC_STRERROR_R.
7319 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
7320 note pessimistic assumption when cross compiling.
7322 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
7324 * doc/autoconf.texi (Limitations of Make): Note that BSD make
7325 (until 2004) invoked subcommands with sh -e, contra POSIX.
7326 Reported by Kevin Ryde.
7328 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
7330 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
7331 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
7332 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
7333 `test -f " /usr/bin/grep"', which _always_ failed.
7334 (AC_PROG_SED): Ditto bogus PATH fix.
7335 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
7336 requires that grep correctly supports _multiple_ `-e' options, rather
7337 than stating only that grep should accept `-e'.
7339 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
7341 Port to C99, which requires that 'exit' be declared.
7343 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
7344 to ensure that stdlib.h is included.
7345 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
7346 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
7347 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
7348 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
7349 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
7350 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
7351 when using 'exit' in a test; C99 requires that 'exit' be declared.
7353 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
7355 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
7356 now prefers 'grep' implementations that accept -e.
7357 (Limitations of Usual Tools): Describe problems of traditional
7358 egrep and fgrep with long input lines, and of traditional grep
7359 with -e.
7360 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
7361 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
7362 All callers changed. Append /usr/xpg4/bin to the PATH, for
7363 Solaris.
7364 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
7365 the user with complaints about multiple -e options.
7366 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
7367 Define it with AC_PROG_GREP.
7368 * configure.ac (AC_PROG_GREP): Add.
7369 * lib/freeze.mk (GREP): New macro.
7371 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
7373 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
7374 a possible candidate only after all others fail, rather than
7375 consulting it first. This improves backward compatibility by
7376 better reflecting the way shell selection occurred in previous
7377 versions of Autoconf, and should help to avoid triggering latent
7378 problems in other packages, such as the one in Automake where zsh
7379 is not handled robustly:
7380 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
7381 Although it is not Autoconf's responsibility to work around
7382 problems in Automake, it nevertheless makes sense to avoid
7383 introducing unnecessary incompatibilites.
7385 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
7386 Gary V. Vaughan <gary@gnu.org>
7388 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
7389 how deeply nested we are when a suitable tool is found, set the
7390 ac_path_TOOL_found flag.
7391 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
7392 nested we are in this macro. Break out of all 3 nested loops if
7393 ac_path_TOOL_found is set.
7395 2004-04-21 Gary V. Vaughan <gary@gnu.org>
7397 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
7398 of the _AS_PATH_WALK loop too if GNU flavor is found.
7400 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
7402 * doc/autoconf.texi (Limitations of Make): Update documentation
7403 for `$<'. New entry `Long lines', based on a report from Simon
7404 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
7405 paragraph about DJGPP, based on a mail from Richard Dawe.
7407 2004-04-20 Paul Eggert <eggert@twinsun.com>
7409 * tests/c.at (C keywords): Don't assume that GCC supports
7410 "restrict" and "inline", as sufficiently-old GCC versions do not
7411 (also, GCC configured to be in pedantic C89 mode does not).
7412 Problem reported by Sumit Pandya in:
7413 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
7415 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
7416 consider -g to work if it generates warnings when plain compiles
7417 don't. Problem reported by Braden McDaniel in:
7418 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
7420 * doc/autoconf.texi (Slashes): New section, to document a problem
7421 reported by Jim Meyering in:
7422 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
7424 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
7425 linker output files before linking, to work around IRIX 6 linker bug.
7426 Problem reported by Rainer Orth in:
7427 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
7429 2004-04-20 Gary V. Vaughan <gary@gnu.org>
7431 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
7432 best tool so far counter rely on the tool path variable name to
7433 avoid checks for one tool being affected by the results of running
7434 the length check on a previous tool.
7436 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
7437 match expression argument, as different greps have different
7438 regular expression flavours.
7439 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
7440 literals.
7441 (AC_PROG_EGREP): Pass 'EGREP$'.
7442 (AC_PROG_GREP): Pass 'GREP$'.
7444 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
7446 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
7447 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
7449 2004-03-29 Paul Eggert <eggert@twinsun.com>
7451 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
7452 Types, Specific Compiler Characteristics, System Services,
7453 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
7454 etc. consistently instead of 'long', 'short', 'unsigned' etc.
7455 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
7456 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
7457 Likewise.
7458 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
7459 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
7460 AC_TYPE_OFF_T): Likewise.
7461 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
7462 Likewise.
7464 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
7465 pacify libtool 1.5.2. Fix quoting problems in sed command.
7467 2004-03-28 Paul Eggert <eggert@twinsun.com>
7469 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
7470 now defines HAVE_DECL_TZNAME if it is declared, when
7471 HAVE_STRUCT_TM_TM_ZONE is not defined.
7472 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
7473 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
7474 for HAVE_TZNAME.
7476 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
7478 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
7479 superfluous backslashing of quotes (") in sed expressions;
7480 thanks to Paul Eggert.
7482 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
7484 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
7485 Fortran compiler is ifort, also added pghpf; thanks to Nelson
7486 H. F. Beebe for the bug report.
7488 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
7490 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
7491 quoted -cmdline argument in Portland Group compiler (bug
7492 reported by Jeffrey J. Barteet).
7494 2004-03-25 Kevin Ryde <user42@zip.com.au>
7496 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
7497 (Run Time): ... here, where it's now mentioned.
7499 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
7501 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
7502 inherits from language Autoconf-without-aclocal-m4.
7503 (Customizing autom4te): Adjust example; the cache must now be
7504 disabled for language Autoconf-without-aclocal-m4.
7506 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
7507 Nathanael Nerode <neroden@twcny.rr.com>

7515 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
7516 AC_CHECK_TARGET_TOOLS, and warn for future changes
7517 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
7518 AC_CHECK_TOOLS.
7519 (Specifying Names): Document the reason for these future
7520 behavioral changes.
7521 * tests/mktests.sh: Do not generate tests for the
7522 new macros.
7523 * NEWS: Document these changes.
7525 * doc/autoconf.texi: Avoid macros with unbraced arguments,
7526 they make TeX hang up.
7528 2004-03-15 Paul Eggert <eggert@bogus.example.com>
7530 * NEWS: New macro AC_CHECK_ALIGNOF.
7531 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
7532 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
7533 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
7534 vowel.
7535 (AC_CHECK_ALIGNOF): New macro.
7536 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
7537 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
7538 those for sizeof.
7540 2004-03-03 Paul Eggert <eggert@twinsun.com>
7542 * bin/Makefile.am (edit): Don't use $< in a context where
7543 POSIX doesn't require support for it. Use $@.in instead.
7544 Problem reported by Anthony N. Frasso in
7545 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
7546 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
7548 2004-02-23 Gary V. Vaughan <gary@gnu.org>
7550 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
7551 from the next generation of Libtool.
7552 * lib/autom4te.in (Autoreconf-preselections): Ditto.
7554 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7556 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
7557 is not always thread-safe. Report from Nathanael Nerode.
7559 2004-02-18 Paul Eggert <eggert@twinsun.com>
7561 Fix a dependencies problem, stemming from a Autoconf 2.59 build
7562 problem on QNX reported by Stephen Rasku in
7563 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
7565 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
7566 $(m4sh_m4f_dependencies); this removes a FIXME.
7567 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
7568 (MAINTAINERCLEANFILES): Split into pieces,
7569 one per related section. Add $(srcdir)/wrapper.in.
7571 2004-02-09 Paul Eggert <eggert@twinsun.com>
7573 * doc/autoconf.texi (Setting Output Variables): Emphasize that
7574 AC_SUBST provides no portable way to escape literal newlines.
7576 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
7577 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
7578 Darwin uses -lcrt2.o and there's little point to cataloging all
7579 the system variants. Partial fix reported by Andreas Waechter in:
7580 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
7581 for bug reported by Nelson H. F. Beebe in:

7584 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
7586 * doc/autoconf.texi (AU_DEFUN): Fix English,
7587 suggested by Paul Eggert.
7588 * lib/autoconf/autoupdate.m4: Correct reference to
7589 acobsolete.m4, suggested by Alexandre Duret-Lutz.
7591 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
7593 * bin/autoupdate.in: Define __file__ so that warnings
7594 refer to the correct file.
7595 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
7596 the behavior of the third argument.
7597 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
7598 correctly the behavior of the third argument. Document
7599 what the three macros that AU_DEFUN defines do. Fix
7600 warning message when the third argument includes $0
7601 (reported by Alexandre Duret-Lutz).
7603 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
7604 Eric Sunshine <sunshine@sunshineco.com>
7605 Paul Eggert <eggert@twinsun.com>
7607 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
7608 (AS_INIT): Output shell initialization there. Removed optional
7609 parameter. Expand _AS_SHELL_FN_SPY.
7610 (AS_INIT_WITH_SHELL_FN): Removed.
7611 (_AS_SHELL_FN_SPY): New macro.
7612 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
7613 macros.
7614 (AS_SHELL_SANITIZE): Remove loop to find better shell
7615 and documentation for the parameter.
7616 (_AS_DETECT_BETTER_SHELL): Move it here.
7617 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
7618 (_AS_RUN): Move it here, support testing with eval.
7619 (AS_REQUIRE_SHELL_FN): Require shell functions when
7620 it is used.
7621 (_AS_LINENO_WORKS): Put around braces, we do not
7622 trigger the bash bug anymore.
7623 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
7624 use AS_INIT_WITH_SHELL_FN.
7625 * bin/autoconf.in, tests/wrapper.in: Regenerated.
7627 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
7629 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
7630 * doc/autoconf.texi: Don't say that the third parameter
7631 is broken.
7632 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
7633 (AU_DEFUN): Honor the third parameter, create autoupdate
7634 macros with AU_DEFINE.
7635 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
7636 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

7643 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
7644 * lib/autoconf/status.m4: Remove FIXME.
7645 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
7646 that the macro is not present anymore in the updated
7647 configure.ac.
7648 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
7649 of autoupdate.
7651 2004-01-28 Paul Eggert <eggert@twinsun.com>

7654 copyright years.
7655 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
7656 2003 (except 1997) to the list of copyright years. This undoes
7657 the 2003-05-22 change, which removed the older years from the list.
7658 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
7660 2004-01-27 Gary V. Vaughan <gary@gnu.org>

7664 grep or ggrep program in PATH that accepts as long lines as
7665 possible.
7666 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
7667 AC_PROG_GREP.
7668 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
7669 egrep and fgrep respectively if $GREP -E/-F don't work.
7670 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
7671 _AC_PROG_GREP, and AC_PROG_SED.
7672 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
7673 longest input length accepted by a command.
7674 (AC_PROG_SED): Use it.
7675 * doc/autoconf.texi (Particular Programs): Document the changes.
7676 * NEWS: Updated.
7678 2004-01-27 Paul Eggert <eggert@twinsun.com>
7680 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

7682 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
7683 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
7685 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
7686 bin/autoconf.in, config/Makefile.in, config/config.guess,
7687 config/config.sub, config/install-sh, config/mdate-sh,

7700 sources.
7702 2004-01-26 Paul Eggert <eggert@twinsun.com>
7704 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
7705 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
7706 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
7707 not <inttypes.h>. Problem reported by Tim Mooney in
7708 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
7709 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
7710 Likewise.
7712 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
7713 otherwise "make check" fails because it forbids cmp (I guess
7714 because cmp treats files as binary on DOS-like systems).
7716 * tests/mktests.sh: Update copyright date to 2004, since some tests
7717 have changed in 2004.
7719 2004-01-23 Gary V. Vaughan <gary@gnu.org>
7721 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
7722 non-truncating sed or gsed program in PATH.
7723 * tests/acprograms.at: Add it.

7725 * NEWS: Updated.
7727 2004-01-15 Paul Eggert <eggert@twinsun.com>
7729 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
7730 -std1 disables some useful extensions on Tru64. Problem reported
7731 by N. Lichtmaier in
7732 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
7734 2004-01-14 Paul Eggert <eggert@twinsun.com>
7736 * doc/autoconf.texi (Programming in M4sh): Document that
7737 AS_MKDIR_P succeeds if the destination is a symbolic link
7738 to an existing directory.
7739 (Limitations of Usual Tools): Note that mkdir -p might not
7740 succeed on symlinks to directories.
7742 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
7744 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

7758 2004-01-09 Paul Eggert <eggert@twinsun.com>
7760 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
7761 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
7762 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
7763 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
7764 AC_COMPILE_IFELSE, since we now assume our caller invokes
7765 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
7766 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
7767 of AC_RUN_IFELSE; this avoids the warning mentioned above.
7768 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
7770 2004-01-07 Paul Eggert <eggert@twinsun.com>
7772 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
7773 `"'...'"`, as it's confusing (and I suspect it may not work on
7774 some platforms). The code was incorrect anyway, as it assumed
7775 that \$ evaluated to itself in that context. Reported by
7776 Alexandre Duret-Lutz.
7778 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
7780 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

7794 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
7795 autoscan, autoupdate, ifnames): Don't use chmod -w.

7797 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
7798 "chmod -w".

7813 * Makefile.am (autom4te-update):

7824 srcdir): Likewise.
7825 * doc/autoconf.texi (Limitations of Usual Tools):
7826 Warn against "rm -fr".
7828 2004-01-03 Paul Eggert <eggert@twinsun.com>
7830 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
7831 -c -o might not work. From a suggestion by Kevin Ryde.
7832 (C Compiler, Generating Sources, Limitations
7833 of Usual Tools, Limitations of Make, Making testsuite Scripts):
7834 Don't put '-o' after non-options, as POSIX doesn't allow this.
7835 Mention that cc's name might be gcc or c89 or whatever.
7837 2004-01-04 Kevin Ryde <user42@zip.com.au>
7839 * doc/autoconf.texi: Add various further index entries.
7841 2003-12-29 Paul Eggert <eggert@twinsun.com>
7843 * bin/autoreconf.in (autoreconf_current_directory):
7844 Fix typo: mkdir without umask arg.
7846 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
7848 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
7849 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

7862 * tests/atlocal.in: Store the result here.

7888 functions work.
7889 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
7890 does not work.
7891 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

7910 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

8161 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
8162 cache variable instead of $G77 to decide whether to include -O2,

8215 * lib/Autom4te/XFile.pm: Use Errno.
8216 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
8217 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
8219 2003-09-30 Akim Demaille <akim@epita.fr>
8221 * config/announce-gen (&print_news_deltas): Extracted from...
8222 (&print_changelog_deltas): here.
8223 (&news_file): Rename as...
8224 (@news_file): this.
8226 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
8228 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
8229 have been created when invoking the compiler.

8240 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
8241 Problem reported by Lars J. Aas in
8242 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
8243 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
8244 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
8245 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
8247 2003-09-26 Akim Demaille <akim@epita.fr>
8249 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
8250 directory for AC_CONFIG_COMMANDS' first argument exists.
8251 This makes valid the invocation of _AC_SRCPATH that follows.
8252 Reported by Eric Sunshine.
8253 * doc/autoconf.texi (Configuration Commands): Adjust.
8255 2003-09-26 Akim Demaille <akim@epita.fr>
8257 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
8258 Reported by Ralf Corsepius.
8260 2003-09-26 Akim Demaille <akim@epita.fr>
8262 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
8263 arguments.
8264 Actually, use AU_ALIAS.
8265 From Bruno Haible.
8267 2003-09-26 Paul Eggert <eggert@twinsun.com>
8269 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
8270 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
8271 Problem reported by Eric Sunshine in:
8272 http://mail.gnu.org/archive/html/autoconf-patches/2002-12/msg00014.html
8274 2003-09-26 Akim Demaille <akim@epita.fr>
8276 The test suite are sometimes assigning timings incorrectly.
8277 Reported by Henk Krus.
8278 Diagnosed by Nicolas Joly.
8280 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
8281 AT_help_all.
8282 Instead of making AT_help a sequence of assignments to grow
8283 $at_help_all, just make AT_help_all be the growing contents of
8284 $at_help_all, and make a single assignment in...
8285 (AT_INIT): here.
8286 (at_times_skip): Flip the meaning and rename as...
8287 (at_times_p): this.
8288 (AT_INIT): When summarizing the test that ran, remove
8289 $at_times_file after use, and check it is present before trying to
8290 use it.
8292 2003-09-25 Akim Demaille <akim@epita.fr>
8294 Version 2.57d.
8296 * bin/Makefile.am (edit): Handle '@configure_input@'.
8297 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
8298 (ifnames): chmod -w.
8299 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
8300 executables, not bin/ executables! Otherwise all the magic needed
8301 to find non installed files is turned off. This caused a failure
8302 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
8303 as found in its environment (sent by tests/autoreconf): pointing
8304 to bin/autom4te that could not find its files.
8305 * tests/mktests.sh: Force the replacement of generated files, for
8306 the sake of "mv" program that are interactive when overwriting a
8307 -w file.
8308 * config/install-sh: Upgrade from CVS Automake.
8310 2003-09-23 Paul Eggert <eggert@twinsun.com>
8312 * doc/autoconf.texi (Limitations of Builtins): Document test -h
8313 versus test -L issues.
8315 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
8316 Paul Eggert <eggert@twinsun.com>
8318 Trivial change to support GCC's configuration procedure.
8319 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
8320 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
8321 about inconsistency if the preprocessor is set to give errors for
8322 any warning.
8323 * doc/autoconf.texi (C Compiler Characteristics): Document this.
8325 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
8327 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
8328 and XFile.pm from Automake.
8329 * lib/Autom4te/XFile.pm: Update from Automake.
8331 2003-09-12 Akim Demaille <akim@epita.fr>
8333 Version 2.57c.
8335 2003-09-12 Akim Demaille <akim@epita.fr>
8337 * config/config.guess, config/config.sub, config/missing,
8338 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
8339 from masters.
8341 2003-09-12 Akim Demaille <akim@epita.fr>
8343 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
8344 not asm/types.h.
8346 2003-09-11 Akim Demaille <akim@epita.fr>
8348 * doc/autoconf.texi (Header Portability): linux/random.h.
8349 From Peter Hendrickson.
8351 2003-09-10 Akim Demaille <akim@epita.fr>
8353 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
8354 willing to edit the output files.
8356 2003-09-10 Akim Demaille <akim@epita.fr>
8358 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
8359 and AC_FC_FREEFORM.
8360 * tests/mktests.sh: Skip AC_FC_SRCEXT.
8361 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
8363 2003-09-09 Akim Demaille <akim@epita.fr>
8365 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
8366 Reported by Gary Vaughan.
8367 * bin/autom4te.in (handle_m4): Likewise.
8369 2003-09-09 Akim Demaille <akim@epita.fr>
8371 * lib/Autom4te/FileUtils.pm (&update_file): Be sure not to leave
8372 trailing files.
8374 2003-09-07 Paul Eggert <eggert@twinsun.com>
8376 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
8377 Improve the accuracy of the wording about obsolescence.
8378 From a suggestion by Ian Lance Taylor in
8379 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
8381 2003-09-05 Paul Eggert <eggert@twinsun.com>
8383 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
8384 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
8386 2003-09-04 Akim Demaille <akim@epita.fr>
8388 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
8389 AC_FUNC_WAIT3.
8391 2003-09-04 Akim Demaille <akim@epita.fr>
8393 * bin/autom4te.in: Use &fatal where more appropriate than &error.
8394 (freeze): When exiting, use $exit_code.
8395 * lib/autoconf/fortran.m4: Comment changes.
8397 2003-09-04 Akim Demaille <akim@epita.fr>
8399 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
8401 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
8403 Add support for newer Fortran dialects. The F77 interface is
8404 unchanged, and continues to support Fortran 77. New FC macros
8405 correspond to all the old F77 macros, with output variables FC,
8406 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
8407 available dialect, but older dialects can be specified. There are
8408 new macros AC_FC_SRCEXT to set the source extension, and
8409 AC_FC_FREEFORM to accept free-form source files.
8411 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
8412 New macros.
8413 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
8414 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
8415 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
8416 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),
8417 AC_LANG_PROGRAM(Fortran), AC_LANG_CALL(Fortran),
8418 AC_LANG_PREPROC(Fortran), AC_LANG_COMPILER(Fortran),
8419 _AC_FC_DIALECT_YEAR, _AC_F95_FC, _AC_F90_FC, _AC_F77_FC,

8428 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
8429 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
8430 Rewrite in terms of the above.
8431 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
8432 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
8433 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
8434 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
8436 2003-09-02 Paul Eggert <eggert@twinsun.com>
8438 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
8439 Document problems with timestamp resolution that 'make', 'cp -p', and
8440 'touch -r' have.
8442 2003-08-27 Akim Demaille <akim@epita.fr>
8444 * tests/m4sugar.at (cross_warning): Make sure to enable the
8445 output, so that we can track spurious m4sugar output.
8446 * tests/local.at: Require 2.57.
8447 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
8448 are defaulted by AT_CHECK anyway.
8449 Use AT_CHECK_AUTOM4TE.
8450 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
8451 missing dnl.
8453 2003-08-27 Akim Demaille <akim@epita.fr>
8455 * bin/autoheader.in: Issue the "Using auxiliary..." message only
8456 when -Wobsolete is set.
8457 Set it on by default.
8458 Suggested by Klee Dienes.
8460 2003-08-27 Akim Demaille <akim@epita.fr>
8462 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More

8506 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
8507 Replace the former...
8508 (m4_warn): Pass the call stack to _m4_warn.
8509 * bin/autom4te.in: Adjust to output the call stack.
8510 * tests/m4sugar.at (m4@&t@_warn): Adjust.
8512 2003-08-22 Akim Demaille <akim@epita.fr>
8514 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
8515 * bin/autom4te.in: Adjust.

8519 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
8520 (&verbose): Remove.

8533 * lib/Autom4te/General.pm: Don't export error: you don't own it.
8535 2003-08-21 Akim Demaille <akim@epita.fr>
8537 First stab at preserving warnings between calls to autom4te,
8538 including when the cache is used.
8540 There are still several issues: (i) there are too many runs of m4
8541 (one for include, one for warnings, and some more), (ii) warnings
8542 spreading on several lines are not handled gracefully, (iii) the
8543 code meant to have the call stack display for errors does not work
8544 (its handling should move from m4 to autom4te).
8546 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
8547 Use them.
8548 (@preselect): Add m4_warn.
8549 ($exit_status): Remove, use $exit_code.
8550 ($help): Use Autom4te::ChannelDefs::usage.
8551 (&handle_m4): No longer define the m4_warnings.
8552 At each run, extract and report the warnings.
8553 Always cache the result, including if the exit status is on
8554 failure, since if nothing changes, we should result in the same
8555 failure, hence we can use the cache.
8556 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
8557 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
8558 Remove.
8559 (m4_warn): Redefine as a do-nothing: it is its invocation that
8560 matters, as warnings are now reported via traces.
8561 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
8562 the contents of m4_warn: make it _call_ m4_warn, so that tracing
8563 the latter reveals calls to the former.
8565 Adjust the tests.
8567 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
8569 2003-08-21 Akim Demaille <akim@epita.fr>
8571 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
8572 Use them.
8574 2003-08-21 Akim Demaille <akim@epita.fr>
8576 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
8577 forward order.
8578 * lib/Autom4te/ChannelDefs.pm: Doc typos.
8579 (&parse_warnings): Accept a list of warning requests.
8580 (&usage): Return a string, not a side effect.
8581 (cross): New warning category.
8583 2003-08-21 Akim Demaille <akim@epita.fr>
8585 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
8586 (&require_configure_ac): Accept an optional directory argument.
8587 ($configure_ac): Remove.
8588 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
8589 (&catfile): Remove.
8590 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
8591 * bin/autoscan.in: Adjust.
8593 2003-08-20 Akim Demaille <akim@epita.fr>
8595 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
8596 Reported by Alexandre Duret-Lutz.
8598 2003-08-20 Akim Demaille <akim@epita.fr>
8600 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
8601 * bin/autom4te: Adjust.
8602 In particular, be Autoconf tools are really silent when properly
8603 working, bind the verbosity of the 'note' channel to $verbose.
8604 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
8605 (&xsystem, &contents): Remove, since they are exported by...
8606 * lib/Autom4te/FileUtils.pm: this.
8607 More perldoc.
8608 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
8609 * lib/Autom4te/FileUtils.pm: here.
8611 2003-08-20 Akim Demaille <akim@epita.fr>
8613 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
8614 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

8641 and m4_sinclude.
8643 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
8645 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...

8664 2003-08-14 Derek Price <derek@ximbiot.com>
8666 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
8667 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
8668 shorter column three. Add DESCRIPTION to log file content.
8670 2003-08-13 Derek Price <derek@ximbiot.com>
8672 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
8673 output.
8675 2003-08-12 Derek Price <derek@ximbiot.com>
8677 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
8678 (AT_CHECK_NOESCAPE): Move core functionality to...
8679 (_AT_CHECK): ...this new macro.
8681 2003-08-07 Derek Price <derek@ximbiot.com>

8686 2003-07-31 Paul Eggert <eggert@twinsun.com>
8688 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
8689 in Bash 2.01. Problem reported by Brian Gough in
8690 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
8692 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
8694 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
8695 -lcrt1.o, for OS X. (trivial change)
8697 2003-07-07 Paul Eggert <eggert@twinsun.com>
8699 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
8700 inside '#ifndef __cplusplus'. Problem reported by
8701 Bob Friesenhahn.
8703 2003-07-06 Bill Clarke <llib@computer.org>
8705 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
8706 'long', not 'int', for benefit of Sun's recent C++ compilers
8707 (trivial change). See:
8708 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
8709 (This really should be 'intptr_t', not 'long', but that would
8710 take more work.)
8712 2003-06-25 Akim Demaille <akim@epita.fr>
8714 * lib/Makefile.am (autom4te.cfg): Make it read only.
8715 Depend on Makefile since it contains substitutions.
8716 From Paolo Bonzini.
8717 * lib/autom4te.in (args): Add local.at? for Autotest args.
8718 This change was made on autom4te.cfg which is generated.
8719 Reported by Raja R. Harinath.
8721 2003-06-25 Akim Demaille <akim@epita.fr>
8723 * doc/autoconf.texi (Header Portability): sys/mount.h.
8724 From Gareth McCaughan.
8726 2003-06-23 Akim Demaille <akim@epita.fr>
8728 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
8729 not all of them. This fixes 1. the fact that when testing
8730 Autoconf there are many many config.log, 2. the incorrect use of
8731 top_srcdir to find config.log.
8732 Don't mix the detailed output of failed test with the summary of
8733 failures. Rather, append detailed log afterwards.
8735 2003-06-23 Akim Demaille <akim@epita.fr>
8737 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
8738 always run: output config.log on $at_group_log.
8740 2003-06-23 Akim Demaille <akim@epita.fr>
8742 * tests/torture.at (#define header templates): Don't use quotes in
8743 C++ comments as it puzzles Emacs' sh font-lock-mode.
8745 2003-06-23 Akim Demaille <akim@epita.fr>
8747 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
8748 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
8749 * tests/atspecific.m4: Rename as...
8750 * tests/local.at: This.
8751 * tests/suite.at: Move the globals into...
8752 * tests/local.at: here.
8753 * tests/Makefile.am: Adjust.
8754 * doc/autoconf.texi (testsuite Scripts): Adjust.
8756 2003-06-21 Kevin Ryde <user42@zip.com.au>
8758 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
8759 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
8760 ensuring we add -std1 for full-ANSI.
8762 * doc/autoconf.texi (hdrindex): New macro.
8763 Add index entries for portability of various standard header files.
8765 2003-06-20 Akim Demaille <akim@epita.fr>
8767 * configure.ac: Bump to 2.57b.
8769 2003-06-20 Akim Demaille <akim@epita.fr>
8771 Version 2.57a.
8773 2003-06-20 Akim Demaille <akim@epita.fr>
8775 * bin/autom4te.in: Don't rely on $HOME being defined.
8776 Reported by Marc Espie as PR/233.
8778 2003-06-20 Akim Demaille <akim@epita.fr>
8780 * lib/autotest/general.m4: Use at_times_file only if used.
8781 From Nicolas Joly.
8783 2003-06-20 Akim Demaille <akim@epita.fr>
8785 * config/config.guess, config/config.sub, config/elisp-comp,
8786 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
8787 Update from masters.
8789 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
8791 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
8792 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
8793 (TEST_SCRIPT): New diversion.
8794 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
8795 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
8796 (AT_INIT): Support for expected failures.
8798 2003-06-02 Akim Demaille <akim@epita.fr>
8800 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
8801 changes.
8802 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
8803 Autoconf nor Automake.
8804 (&contents): New, from Automake.
8805 PODify.
8807 2003-05-28 Paul Eggert <eggert@twinsun.com>
8809 * NEWS, doc/autoconf.texi (Particular Functions),
8810 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
8811 is the inverse of localtime.
8813 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
8815 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
8816 (handle_exec_errors): New function. Work around $! being
8817 altered by WEXITSTATUS.
8818 (xqx, xsystem): Use handle_exec_errors.
8820 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
8822 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
8823 Do not call `_exit()', simply modify `$?'.
8824 (xsystem): Reset $! before running system, and check it afterward.
8825 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
8826 63 for version mismatches.
8828 2003-05-23 Akim Demaille <akim@epita.fr>
8830 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
8831 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
8832 the middle of a line).
8833 * lib/m4sugar/m4sugar.m4: Likewise.
8834 Remove useless spaces in comments.
8836 2003-05-23 Akim Demaille <akim@epita.fr>
8838 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
8839 exit 63, so that we (or Automake's "missing") can tell the
8840 difference with a plain failure.
8841 * doc/autoconf.texi (Notices): Adjust.
8843 2003-05-23 Akim Demaille <akim@epita.fr>
8845 * Makefile.am, bin/Makefile.am, config/Makefile.am,
8846 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
8847 White spaces cleanup.
8849 2003-05-22 Jim Meyering <jim@meyering.net>
8850 Paul Eggert <eggert@twinsun.com>
8852 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
8853 Remove `#include <stdlib.h>' from the list; we should never
8854 make confdefs.h include <stdlib.h> or <cstdlib>, because the
8855 resulting namespace pollution would cause other tests to fail.
8856 Configure scripts run with some older versions of g++ and HP's
8857 aCC would fail due to such an #include. Problems reported by
8858 Matthew Mueller in <http://bugs.debian.org/120704> and by
8859 Keith Bostic in
8860 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
8861 In the test, use the test declaration before including <stdlib.h>,
8862 as that's closer to how it'll be used.
8864 2003-05-23 Akim Demaille <akim@epita.fr>
8866 * doc/autoconf.texi (Header Portability): ucred.h.
8867 From Ian Redfern.
8869 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8871 Overhaul Autotest's logging: generate separate log files
8872 in testsuite.dir/NNN/testsuite.log, and append them to
8873 testsuite.log instead of re-running the test verbosely.
8875 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
8876 file descriptor, write 0 to at_status_file instead of setting
8877 at_status=0, initialize some new variables (at_status_file,
8878 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
8879 to rerun the tests, instead append the at_group_log to the
8880 at_suite_log when a test fails.
8881 (AT_SETUP): pipe the test case's output into at_tee_pipe,
8882 with the AS_MESSAGE_LOG_FD redirected to stdout.
8883 (AT_CLEANUP): save the output status in $at_status_file
8884 and restore it, redirect the AS_MESSAGE_LOG_FD back to
8885 its original place.
8886 (AT_CHECK): since tests are run with a redirected stdout,
8887 and used to be re-run in verbose mode, turn some $at_verbose
8888 into echo, and don't redirect the output of testing stdout
8889 and stderr.
8891 * lib/autotest/autoconf.texi (testsuite Scripts): Update
8892 the name of the debugging directory and information about
8893 its contents.
8895 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8897 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
8898 parameter.
8900 2003-05-22 Akim Demaille <akim@epita.fr>
8902 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4

8920 Whitespace clean up.
8921 Suggested by Jim Meyering.
8923 2003-05-22 Akim Demaille <akim@epita.fr>
8925 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed

8927 Reported by Jim Meyering.
8929 2003-05-22 Akim Demaille <akim@epita.fr>
8931 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

8962 AC_CHECK_HEADERS_NEW): New tests.
8964 2003-05-17 Akim Demaille <akim@epita.fr>
8966 * lib/autoconf/functions.m4: Use the default includes so that
8967 memcmp be declared before being tested.
8968 Reported by Sander Niemeijer.
8969 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
8970 * doc/autoconf.texi (Default Includes): Document
8971 AC_INCLUDES_DEFAULT.
8973 2003-05-17 Akim Demaille <akim@epita.fr>
8975 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
8976 * doc/autoconf.texi (Obsolete Macros): Adjust.
8977 Reported by Werner LEMBERG and Debian Bug 190886.
8979 2003-05-16 Akim Demaille <akim@epita.fr>
8981 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
8982 user name space clashes.
8983 Reported by Bruno Haible.
8985 2003-05-16 Akim Demaille <akim@epita.fr>
8987 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
8988 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
8989 them uniform, and more robust to Perl special characters.
8990 Reported by Martin Mokrejs.
8992 2003-05-14 Akim Demaille <akim@epita.fr>
8994 * tests/foreign.at (Libtool): Skip all Libtools pre 1.4.

8998 * doc/autoconf.texi (Header Portability): X11/extensions/scrnsaver.h,

9003 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Improve the
9004 message.
9005 From Matthias Andree.
9007 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
9009 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
9010 and truncate.
9012 2003-05-06 Akim Demaille <akim@epita.fr>
9014 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
9015 longer updates aclocal.m4 if useless, (ii) if a file m4_included
9016 by aclocal.m4 is changed it might require the importing of another
9017 m4 extension file, i.e., aclocal must be run.
9019 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
9020 (&parse_args): Use --force with aclocal if required and supported.
9021 (&autoreconf_current_directory): Use &run_aclocal.

9025 Lock autom4te's cache.
9027 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
9028 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
9029 argument instead of a file name, so that the request file remains
9030 open during the whole autom4te run.
9031 ($icache_file): New.
9032 (&freeze): Lock the $icache_file.
9034 2003-04-29 Derek Price <derek@ximbiot.com>
9036 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
9037 seperator with m4_append_uniq(). It doesn't work.
9038 (AT_CLEANUP): Add `;' to end of at_help_all.
9039 (AT_INIT): Allow --keywords to be specified more than once. When
9040 grepping $at_help_all for keywords, use the field and keyword
9041 seperators to ensure a complete keyword match. Alter at_prev handling
9042 to support the new --keywords behavior.
9044 2003-04-27 Karl Berry <karl@freefriends.org>
9046 * doc/autoconf.texi: Make the dir entries in the autoconf manual
9047 align better with others. I also made some of the individual
9048 entries on one line, for brevity and to make it easier for me to
9049 sort my dir-example file in the Texinfo distribution :).
9051 2003-04-12 Jim Meyering <jim@meyering.net>
9053 * NEWS: Mention the new macro.
9054 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.
9055 * doc/autoconf.texi (C Compiler): Describe AC_C_RESTRICT.
9056 * tests/c.at: Test AC_C_RESTRICT.

9067 From Ilya Zakharevich.
9069 2003-04-08 Akim Demaille <akim@epita.fr>
9071 * doc/autoconf.texi (Particular Headers): Some about sys/socket.h,
9072 net/if.h, stdlib.h.

9084 2003-04-01 Akim Demaille <akim@epita.fr>
9086 * doc/autoconf.texi (ac, at, ms): Rename these indexes as...
9087 (AC, AT, MS): these.
9088 (shortindexflag, @acindex, @ahindex, @asindex, @atindex, @msindex):
9089 New.
9090 Use them.
9091 * doc/Makefile.am (CLEANFILES): Adjust.
9092 (TEXI2DVI): Make it --batch.
9094 2003-03-31 Derek Price <derek@ximbiot.com>
9096 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
9097 which removed the main loop.
9098 Thanks to Akim Demaille.
9100 2003-03-29 Akim Demaille <akim@epita.fr>
9102 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Skip OS/2's install,
9103 that starts a GUI.
9104 From Ilya Zakharevich.
9106 2003-03-29 Akim Demaille <akim@epita.fr>
9108 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The
9109 documentation to read is Autoconf's.
9110 Suggested by Paul Eggert.
9112 2003-03-28 Akim Demaille <akim@epita.fr>
9114 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
9115 reading the section "Present But Cannot Be Compiled" when the
9116 header causes problems.
9118 2003-03-28 Akim Demaille <akim@epita.fr>
9120 * tests/torture.at (Configuring subdirectories): Require aclocal
9121 1.4, otherwise the test fails, as it does support configure.ac.
9122 This fixes the "test 40 failed" bug reports.
9124 2003-03-28 Akim Demaille <akim@epita.fr>
9126 * doc/autoconf.texi (C Compiler): `#line' portability.
9127 From Paul Eggert and Nelson H. F. Beebe.
9129 2003-03-27 Derek Price <derek@ximbiot.com>
9131 * lib/autotest/general.m4: Eliminate main loop and reorganize test
9132 layout in order to allow scripting around test groups.
9134 2003-03-27 Derek Price <derek@ximbiot.com>
9136 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
9137 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
9138 use new diversions in preparation for accepting new arguments and
9139 allowing scripting around tests.
9140 (OPTIONS,TAIL): Remove these diversions to make way for the ones above.
9142 2003-03-26 Derek Price <derek@ximbiot.com>

9152 2003-03-26 Derek Price <derek@ximbiot.com>
9154 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
9155 sense. Verbosify the diversion definitions comment.
9157 2003-03-26 Derek Price <derek@ximbiot.com>
9159 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to
9160 AS_PREPARE.
9162 2003-03-21 Eric Siegerman <eric_97@pobox.com>
9164 * doc/autoconf.texi (Present But Cannot Be Compiled):
9165 Grammar fixes and minor rewording. (trivial change)
9167 2003-03-06 Paul Eggert <eggert@twinsun.com>
9169 Work around a problem noted by Nelson H. F. Beebe with coreutils

9195 (Automake): Automake 1.5+ no longer requires special tools to be
9196 present on the developer's host.
9198 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>

9213 to cope with DOS-style absolute paths, when constructing
9214 ${ac_make}.
9216 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
9217 When constructing paths with IFS=:, quote the path. If we're
9218 constructing a DOS-style absolute path, we don't want to split it
9219 on the colon.
9221 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
9222 in description.

9236 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
9237 to fix a mismatch between example and discussion.
9239 2003-02-24 Kevin Ryde <user42@zip.com.au>
9241 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
9242 format starting with "-".
9244 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9246 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
9247 is not portable inside Makefile.
9249 2003-02-20 Akim Demaille <akim@epita.fr>
9251 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
9252 compiler says yeah, but preproc says nope, compiler is right.
9253 Conversely, prompt the reader to send a bug report to the
9254 maintainers of the package, not of Autoconf.

9264 $ac_prefix_program.
9265 From Larry Jones.
9267 2002-12-23 Paul Eggert <eggert@twinsun.com>
9269 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
9270 innocuous variant befor including <limits.h> or <assert.h>. This
9271 works around a bug reported by Albert Chin: HP-UX 11i
9272 (and earlier versions) have a <limits.h> that declares
9273 gettimeofday and many other functions.
9275 2002-12-03 Paul Eggert <eggert@twinsun.com>
9277 Version 2.57.
9279 * NEWS, configure.ac: Update version.
9281 * doc/fdl.texi: Upgrade to FDL version 1.2.
9283 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
9284 nontrivially in main's body, so that f's external declaration is
9285 not optimized away in AIX. This should fix the bug reported by
9286 Martin Frydl in
9287 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
9289 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
9290 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
9291 defined, to support freestanding compilers. This should fix the
9292 bug reported by Momchil Velkov in
9293 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
9295 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
9296 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

9307 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
9308 \(.*\) match is too long and there is something more to be checked.
9309 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
9311 2002-11-15 Akim Demaille <akim@epita.fr>

9317 * config/move-if-change: Indenting changes.
9318 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
9319 * configure.ac (AM_INIT_AUTOMAKE): here.
9320 Require 1.7.1.
9322 2002-11-14 Akim Demaille <akim@epita.fr>
9324 Version 2.55.
9326 * config/config.guess, config/config.sub, config/install-sh:
9327 Update from masters.
9329 2002-11-14 Akim Demaille <akim@epita.fr>
9331 * Makefile.maint: Sync with Bison, i.e.:
9332 (po-check): Scan .l and .y files instead of the
9333 .c and the .h files that they generate. This fixes the bug
9334 reported by Tim Van Holder in:
9335 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
9336 Look for N_ as well as for _. Try to avoid matching #define for
9337 N_ and _.
9338 From Paul Eggert.
9340 2002-11-14 Akim Demaille <akim@epita.fr>
9342 * doc/autoconf.texi (C Compiler): Compiling several files at once.
9343 From Paul Eggert and Albert Chin-A-Young.
9345 2002-11-14 Akim Demaille <akim@epita.fr>
9347 * doc/autoconf.texi (C Compiler): Solitary backslashes.
9348 From Paul Eggert and Albert Chin-A-Young.
9350 2002-11-14 Kevin Ryde <user42@zip.com.au>
9352 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
9353 than assigning in main, to avoid HP cc +O3 optimizing it away.
9355 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
9357 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
9358 option. Process --recheck after parsing all options. Pass -q
9359 option to configure on --recheck.
9360 (AC_OUTPUT): Pass -q from configure to config.status.
9361 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
9362 arguments to record.
9363 * doc/autoconf.texi (config.status Invocation): Document
9364 config.status -q option.
9366 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

9369 Makefile.in if Makefile.am exists.

9371 output AC_CONFIG_FILES if no Makefiles were found.
9373 2002-11-07 Akim Demaille <akim@epita.fr>

9382 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
9383 declaration in extern "C" too.

9388 * tests/torture.at (Configuring subdirectories): Don't use grep
9389 -w.
9390 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
9391 Reported by Ezra Peisach.
9393 2002-11-05 Akim Demaille <akim@epita.fr>
9395 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
9396 Remove.
9397 We _have_ to stop using the old compatibility scheme that tried to
9398 avoid useless backslashes because Libtool 1.4.3 contains a
9399 AC_DEFINE([error_t], [int],
9400 [Define to a type to use for \`error_t' if it is not
9401 otherwise available.])
9402 We _have_ to quote the single quote and backslashes with \. The
9403 old compatibility scheme saw that ` was backslashed, and therefore
9404 did not quote the single quote. Hence before this patch, Autoconf
9405 was not compatible with Libtool.
9407 2002-11-04 Paul Eggert <eggert@twinsun.com>
9409 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
9410 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
9411 LC_NAME, LC_PAPER, LC_TELEPHONE.

9414 2002-11-04 Akim Demaille <akim@epita.fr>
9416 Version 2.54c.
9418 * Makefile.maint (update, cvs-update, po-update, do-po-update):

9420 * config/texinfo.tex: Update.
9422 2002-11-03 Akim Demaille <akim@epita.fr>
9424 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
9425 from...
9426 (&autoreconf): here.
9427 ($help, $make, &parse_args, &autoreconf_current_directory):
9428 Support -m/--make.
9429 * doc/autoconf.texi (autoreconf Invocation): Adjust.

9445 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
9447 2002-10-31 Akim Demaille <akim@epita.fr>
9449 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
9450 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
9451 Make variable, not a shell variable.
9452 Suggested by Bruno Haible.
9454 2002-10-31 Akim Demaille <akim@epita.fr>
9456 * bin/autom4te.in (load_configuration): Reject #args out of any
9457 language.
9459 2002-10-31 Akim Demaille <akim@epita.fr>
9461 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.

9473 Suggested by Tim van Holder.
9475 2002-10-29 Paul Eggert <eggert@twinsun.com>
9477 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
9478 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
9479 Problem reported by Bruno Haible.
9481 2002-10-29 Akim Demaille <akim@epita.fr>
9483 * doc/autoconf.texi (Header Templates): Put also in words what the
9484 pictures says to assist free style readers.
9485 (Customizing autom4te): s/--cache=/--cache /.
9487 2002-10-29 Akim Demaille <akim@epita.fr>
9489 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
9490 sys/wait.h.
9491 sparc_address_test returns void.
9492 Use it with an argument, as prototyped.
9493 From Bruno Haible.
9495 2002-10-29 Akim Demaille <akim@epita.fr>
9497 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

9503 * tests/torture.at (Deep Package): New test.

9509 * bin/autoreconf.in (&parse_args, $help): Support --warnings.
9510 * doc/autoconf.texi (Invoking autom4te): Rename as...

9714 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Avoid duplicates in
9715 `$ac_configure_args'.
9717 2002-10-22 Akim Demaille <akim@epita.fr>

9737 2002-10-22 Akim Demaille <akim@epita.fr>
9739 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
9740 are a few warnings.
9741 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
9742 Quote for Perl '' strings, not "".
9743 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
9744 strings.
9746 2002-10-22 Akim Demaille <akim@epita.fr>
9748 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
9749 characters is a syntax warning now.

9751 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):

9756 `@', to tickle Perl's lists.
9757 Reported by Carlos Velasco.
9759 2002-10-18 Akim Demaille <akim@epita.fr>
9761 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that

9771 2002-10-17 Akim Demaille <akim@epita.fr>
9773 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.
9774 Fixes the `AC_ARG_VAR' test failures.

9790 (ansi2knr.c-url_prefix): Remove.
9792 2002-10-16 Akim Demaille <akim@epita.fr>
9794 Because of caching, some files that no longer exist and are no
9795 longer required can still cause errors.
9796 Reported by Alexandre Duret-Lutz.
9798 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
9799 to frozen files in @ARGV, as @ARGV must remain being a list of
9800 files. Rather, at M4 call sites, use this...
9801 (&files_to_options): New function.
9802 (&freeze): Use &error.
9803 (&up_to_date): If a file that was included according to the cache
9804 is no longer there, then the output is out dated.
9805 (&main): Don't even check whether a file is up to date is anyway
9806 --force is given.
9807 * tests/tools.at (autom4te cache): New.
9809 2002-10-16 Akim Demaille <akim@epita.fr>
9811 * bin/autoconf.as: Kill dead options.
9812 * bin/autoupdate.in (&parse_args): Kill old options.
9813 * bin/autoreconf.in (&parse_args): Remove dead options.
9814 Factor some code.
9815 (&autoreconf): Report the directories we enter *and leave*, so
9816 that error messages can be easily located, and use GNU Make
9817 format, so that Emacs' compile mode understands us.
9818 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
9819 if some file was changed instead of `print'.
9820 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
9821 (&parse_args): Remove the dead options.
9822 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
9823 autoheader's quiet mode.

9828 2002-10-11 Akim Demaille <akim@epita.fr>

9831 check for compilability.
9833 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
9834 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

9836 (AC_CHECK_HEADER): this.
9838 * lib/autotest/general.m4 (AT_INIT): Include the failed test
9839 numbers in the Subject suggestion.

9851 2002-10-11 Akim Demaille <akim@epita.fr>
9853 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
9854 file name to enable parallel executions.
9855 From Sam Varshavchik.
9857 2002-10-08 Akim Demaille <akim@epita.fr>
9859 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
9860 aclocal invocation, as Gettext macros might not be visible to
9861 aclocal.
9862 Instead of blindly running autopoint, scan configure.ac (not the
9863 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
9864 Reported by Paul D. Smith.
9866 2002-10-08 Paul Eggert <eggert@twinsun.com>
9868 Work around problems found when POSIXLY_CORRECT=1 is set.
9869 None of this seems to have anything to do with POSIX, really,
9870 but it's how Perl getopt works.
9871 * bin/autom4te.in (parse_args): Configure GetOpt with
9872 "permute", too.
9873 * doc/autoconf.texi (Invoking autom4te):
9874 --warning -> --warnings.
9875 * lib/autom4te.in: --warning -> --warnings.
9877 2002-09-28 Akim Demaille <akim@epita.fr>

9894 2002-09-28 Akim Demaille <akim@epita.fr>
9896 * tests/torture.at (Configuring subdirectories): Be robust to
9897 users who use config.site to require for a cache: in this case,
9898 the two last configure runs, using two different sets of
9899 arguments, trigger a legitimate error.
9901 2002-09-28 Akim Demaille <akim@epita.fr>
9903 * tests/m4sh.at (Functions Support, Functions and return Support):
9904 New.

9912 * doc/autoconf.texi (Installation Directory Variables): Adjust.
9914 2002-09-28 Akim Demaille <akim@epita.fr>
9916 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
9917 (tm_zone): Move their rules to...
9918 * lib/autoconf/types.m4: here, using AN_ macros.
9919 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
9920 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
9921 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
9922 * lib/autoconf/programs.m4: here.
9923 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
9924 (ETAGS_FOR_AUTOCONF): New.
9925 Use it.
9927 2002-09-28 Akim Demaille <akim@epita.fr>

9932 that were listed in the original autoscan.list.

9934 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
9935 (.m4.m4f): Don't pass --prepend-include, since that's done by
9936 tests/autom4te itself.
9937 * lib/autoscan/Makefile.am: Include freeze.mk.
9938 (autoscan.list): New target --this file is no longer a source.
9939 (autoscan.pre): New file.

9944 Adjust all uses.
9945 (&init_tables): When --debug, report the list of rules to ease
9946 tracking changes in autoscan.list.
9947 * lib/autoscan/autoscan.list (function): Strip comments, sort.
9949 2002-09-28 Akim Demaille <akim@epita.fr>
9951 * lib/autoscan/functions, lib/autoscan/headers,
9952 * lib/autoscan/identifiers, lib/autoscan/makevars,
9953 * lib/autoscan/programs: Merge into...
9954 * lib/autoscan/autoscan.list: this.
9955 * bin/autoscan.in (&init_tables): Adjust.
9957 2002-09-28 Akim Demaille <akim@epita.fr>

9960 * lib/autoscan/identifiers, lib/autoscan/makevars,
9961 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
9962 `functions' line is now prefixed with `function:'.
9963 * bin/autoscan.in (&init_tables): Adjust.
9965 2002-09-28 Akim Demaille <akim@epita.fr>
9967 From now on, autoscan files must always map a macro name to a
9968 word: there is no `default' macro for autoscan.
9970 * bin/autoscan.in (&init_tables): Reject entries with no macro at
9971 all.
9972 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
9973 explicit.
9975 2002-09-28 Akim Demaille <akim@epita.fr>
9977 * bin/autoscan.in (%c_keywords): Remove.
9978 (&used): Keep only track of the words we might be interested in.
9979 (&output_kind): It is no longer needed to look for non active
9980 checks.
9982 2002-09-27 Akim Demaille <akim@epita.fr>

10009 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
10010 Reported by Ralf Corsepius.
10011 * doc/autoconf.texi (autoreconf Invocation): Likewise.
10013 2002-09-26 Akim Demaille <akim@epita.fr>
10015 Single suffix rules and seperated dependencies are not portable.
10017 * doc/autoconf.texi (Installation Directory Variables): Update.

10023 2002-09-25 Paul Eggert <eggert@twinsun.com>

10062 reading config.log when the compiler is rejected.
10063 Suggested by Guido Draheim.
10065 2002-09-13 Akim Demaille <akim@epita.fr>
10067 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
10068 (chdir_init) might hang when stat'ing mounted directories.
10069 Reported by Vance Shipley.
10071 2002-09-12 Akim Demaille <akim@epita.fr>
10073 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
10074 the lists.
10076 2002-09-12 Akim Demaille <akim@epita.fr>
10078 * doc/autoconf.texi (Defining Symbols): Present two different
10079 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the

10084 * doc/autoconf.texi: Review grammar and punctuation.

10089 grammatical typos.
10090 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
10091 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
10092 is obsolescent.
10094 2002-09-11 Akim Demaille <akim@epita.fr>
10096 * doc/autoconf.texi (Questions): Rename as...
10097 (FAQ): this.

10108 plain `@' is wanted.
10110 2002-09-09 Akim Demaille <akim@epita.fr>
10112 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
10113 `duplicates', since the algorithm was too naive and could keep
10114 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
10115 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
10116 Reported by Ralf Corsepius.
10117 * tests/torture.at (Configuring subdirectories): Exercise these
10118 cases.
10120 2002-09-09 Akim Demaille <akim@epita.fr>
10122 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
10123 looking for a replacement file.
10124 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
10125 directory is relative.
10126 * doc/autoconf.texi (Generic Functions): Clarify the replacement
10127 directory definition.
10128 Reported by Andreas Schwab and Jim Meyering.
10130 2002-09-06 Akim Demaille <akim@epita.fr>
10132 * doc/autoconf.texi (Setting Output Variables): Clarify what
10133 precious variables are.
10134 Suggested by Pontus Skoeld.
10136 2002-09-05 Akim Demaille <akim@epita.fr>
10138 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
10139 (ifnames, autoscan, autom4te): Since we don't only depend on
10140 configure.ac variables (such as VERSION etc.), but also on prefix
10141 and so forth, depend on Makefile, not configure.ac.
10142 Reported by Alexandre Duret-Lutz.
10143 * doc/autoconf.texi (Installation Directory Variables): Adjust.
10145 2002-09-05 Kevin Ryde <user42@zip.com.au>
10147 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
10148 doesn't seem to be confined to ia64, just say "some versions".
10150 2002-09-04 Akim Demaille <akim@epita.fr>
10152 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
10153 Automake 1.6c.

10157 2002-09-03 Paul Eggert <eggert@twinsun.com>
10159 * doc/autoconf.texi (Configuration Commands): Remove obsolete
10160 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
10161 Brinkmann.
10163 2002-09-03 Akim Demaille <akim@epita.fr>
10165 * configure.ac: Bump to 2.53d.
10166 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
10167 as of today, on Automake's team suggestion.
10169 2002-09-03 Akim Demaille <akim@epita.fr>
10171 Version 2.53c.
10173 2002-09-02 Akim Demaille <akim@epita.fr>
10175 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
10176 SITE_MACRO_DIR.
10177 * configure.ac: Disable SITE_MACRO_DIR.
10179 2002-09-02 Jim Meyering <meyering@lucent.com>
10181 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
10182 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
10183 Also, tweak grammar: s/make sure to/be sure to/.
10185 2002-09-02 Paul Eggert <eggert@twinsun.com>
10187 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
10188 directory names are generally preferable to physical names.
10190 2002-09-02 Akim Demaille <akim@epita.fr>
10192 * lib/Autom4te/General.pm (&update_file): s/die/error/.
10193 Reported by Raja R. Harinath.
10194 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
10195 * bin/autoupdate.in: Use error instead of die.
10197 2002-09-01 Paul Eggert <eggert@twinsun.com>
10199 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
10200 ordinary shell concatenation rather than echo+tr+sed command that
10201 runs afoul of a long-line-related sed bug in Solaris 8.
10203 * bin/autoheader.in (parse_args): --warning -> --warnings.
10205 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
10206 stdout, as traditional "ls" does.
10207 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
10208 _AC_COMPILER_EXEEXT_O): Likewise.
10209 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
10211 * bin/autoconf.as: Add --prepend-include option. This patch was
10212 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
10213 but bin/autoconf.in is generated automatically from bin/autoconf.as.
10215 * bin/autoconf.in, configure: Regenerate.
10217 * doc/autoconf.texi (Special Shell Variables): Mention
10218 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
10220 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
10221 MAILPATH and set PS1, PS2, PS4 to default values, to work
10222 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
10223 For LC_ALL etc, first try to set to "C" as POSIX requires and as
10224 the Autoconf documentation specifies; fall back to "unset" only if
10225 this fails. Use a shell for-loop for this rather than an m4 loop,
10226 to shorten the output script.
10228 2002-08-30 Paul Eggert <eggert@twinsun.com>
10230 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
10231 1003.1-2001's requirements for CDPATH. Give a simpler workaround
10232 for the CDPATH problem. Document PWD.
10233 (Limitations of Builtins): Document the problem that "cd $foo" and
10234 "ls $foo" may refer to different directories in shells conforming
10235 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
10236 example, since the old example is now out of date.
10238 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
10239 FOO" and "ls FOO" talk about different directories; this catches
10240 problems when POSIX 1003.1-2001 "cd" fails due to symlink
10241 spaghetti.
10243 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
10244 of rolling our own unset.
10245 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
10246 in practice we needn't worry about CDPATH if unset doesn't work.
10248 * Makefile.in, aclocal.m4, bin/Makefile.in,
10249 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
10250 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
10251 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
10252 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
10253 tests/Makefile.in: Regenerate with Automake 1.6.3.
10255 * config/config.guess, config/config.sub, config/mkinstalldirs:
10256 Update.
10258 * configure: Regenerate with self.
10260 2002-08-30 Kevin Ryde <user42@zip.com.au>
10262 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
10263 default output.
10265 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>

10268 failure.
10270 2002-08-29 Akim Demaille <akim@epita.fr>
10272 * lib/Autom4te/General.pm (&xqx): New.
10273 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
10274 hand, which is not portable.
10275 (&error): New.
10276 * bin/autom4te.in: Use them.
10277 Use &error instead of die.
10278 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
10279 Adjust.
10281 2002-08-17 Paul Eggert <eggert@twinsun.com>
10283 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
10284 default list of compilers to try, since it was long ago superseded
10285 by the ksh fc builtin. Suggested by Steven G. Johnson.
10287 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
10289 * doc/autoconf.texi (Invoking autom4te): End the option table,
10290 fixing a bug introduced by the previous patch.
10291 (Limitations of Make): Add a 'target lookup' subentry in the
10292 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
10294 2002-07-29 Mark D. Roth <roth@feep.net>
10296 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
10297 options and use $AUTOM4TE_PATH.
10298 * doc/autoconf.texi: Remove documentation of autom4te
10299 --include-envvar and --site-macro-subdir options and document
10300 use of $AUTOM4TE_PATH.
10301 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
10302 arguments from each language section.
10304 2002-07-29 Paul Eggert <eggert@twinsun.com>
10306 * doc/install.texi: Include copyright symbol in copyright notice.
10308 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
10309 Replace with:
10310 (AM_MAKEINFOFLAGS): New macro.
10311 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
10312 * Makefile.am (INSTALL): Use the new macros.
10313 Use -o rather than --output, since "missing" does not grok --output.
10315 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
10317 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
10318 comments do not always work. Never trust the exit status of
10319 `make -k'.
10321 2002-07-24 Kevin Ryde <user42@zip.com.au>
10323 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
10324 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
10326 2002-07-23 Paul Eggert <eggert@twinsun.com>
10328 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
10329 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
10330 apparently treats PATH="nonexistent" as if it contained ".".
10331 Bug reported by Stefan `Sec' Zehl.
10333 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10335 * doc/autoconf.texi (Limitations of Make): Mention the special

10352 2002-07-18 Akim Demaille <akim@epita.fr>
10354 Version 2.53b.
10356 2002-07-18 Akim Demaille <akim@epita.fr>

10495 of the cache should not depend on the name under which autom4te
10496 was installed.
10498 2002-06-07 Akim Demaille <akim@epita.fr>
10500 * tests/tools.at (autoconf: forbidden tokens, basic)

10601 This improves on an earlier suggestion by H. Peter Anvin.
10603 2002-05-16 Paul Eggert <eggert@twinsun.com>

10615 not for GNU extensions; this undoes part of the 2000-11-03 change,
10616 reverting to 2.13-compatible behavior.
10617 Add new optional argument DIR.
10618 (AC_FUNC_FNMATCH_GNU): New macro.
10620 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
10622 2002-05-08 Paul Eggert <eggert@twinsun.com>
10624 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
10625 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
10626 and it causes a 'test' syntax error if it fails.
10627 Bug reported by Stephen Gildea.
10629 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
10630 If prototypes are supported, use them to check this at compile-time,
10631 instead of trying to check it at run-time. If we must do a run-time
10632 check, assume that setvbuf is standard when cross-compiling, as
10633 nonstandard setvbuf occurs only on ancient and unlikely hosts.
10634 Bug reported by Paul D. Smith.
10636 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
10637 argument specifying location of getloadavg.c. This removes a
10638 FIXME. This idea was taken from Jim Meyering's implementation in
10639 textutils.
10640 * doc/autoconf.texi (Particular Functions): Document this.
10641 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
10642 that's what the code does; this fixes a bug reported by
10643 Paul D. Smith.
10645 2002-05-03 Akim Demaille <akim@epita.fr>
10647 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
10648 autopoint instead of gettextize.
10649 ($uses_alocal): Rename as...
10650 ($uses_aclocal): this.
10651 * doc/autoconf.texi (autoreconf Invocation): Adjust.
10652 Suggested by Bruno Haible.
10654 2002-05-03 Akim Demaille <akim@epita.fr>
10656 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
10658 2002-04-29 Paul Eggert <eggert@twinsun.com>
10660 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
10661 files to be 1 second older; just set them to be the same time.
10662 Also, sleep 1 second after the first aclocal, to work around
10663 problems with sub-second time stamps on the input files.
10665 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
10667 * doc/autoconf.texi: Mention "set -e -x" lossage
10668 under node "Limitations of Builtins".
10670 2002-04-29 Akim Demaille <akim@epita.fr>
10672 * doc/install.texi: Better wording for setting variables when
10673 running configure.
10674 From Christian Cornelssen.
10676 2002-04-29 Akim Demaille <akim@epita.fr>
10678 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
10679 of lack of $LINENO support, then the test will compare the $LINENO
10680 in testsuite vs. the lineno in the test file. This is wrong, of
10681 course.
10682 Be sure to protect it.
10683 Reported by Patrick Welche.
10685 2002-04-25 Akim Demaille <akim@epita.fr>
10687 * doc/autoconf.texi (Obsolete Macros): Typo.
10688 Reported by Vladimir Volovich.
10690 2002-04-25 Akim Demaille <akim@epita.fr>
10692 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
10693 than some of the input files, hence, on the second run of aclocal,
10694 if some of its input are younger, make them older.
10695 Suggested by Paul Eggert.
10697 2002-04-25 Akim Demaille <akim@epita.fr>
10699 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
10700 Thanks to Paul Eggert.
10702 2002-04-25 Akim Demaille <akim@epita.fr>
10704 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
10705 and ac_subst_vars be sh variables containing the list of
10706 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
10707 DEFAULT diversion.
10708 (_AC_INIT_PREPARE): Use them to log them.
10709 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
10710 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
10711 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
10712 _AC_SUBST_FILES and _AC_SUBST_VARS.
10713 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
10715 2002-04-24 Akim Demaille <akim@epita.fr>
10717 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
10718 autoheader, so that automake does not complain about a missing
10719 config.h.in that was to be created.
10721 2002-04-23 Akim Demaille <akim@epita.fr>
10723 * bin/autoheader.in (parse_args): --warning takes an argument.
10724 Fixes PR/220.
10726 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
10728 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
10729 and bb.out when cleaning up.
10731 2002-04-22 Akim Demaille <akim@epita.fr>
10733 Version 2.53a.
10735 2002-04-22 Akim Demaille <akim@epita.fr>

10739 2002-04-22 Akim Demaille <akim@epita.fr>
10741 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
10742 comma.
10743 Reported by Gregory Giannoni.
10745 2002-04-22 Akim Demaille <akim@epita.fr>
10747 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
10748 Fixes false failures on Darwin.

10773 Minor spelling and grammar fixes.
10775 * doc/autoconf.texi: Follow the outline suggested in the GNU
10776 Sample Texts sections of the Texinfo 4.2 manual. Most
10777 importantly, this makes sure that the copyright notices appear in
10778 all output formats. You probably need Texinfo 4.2 to generate
10779 the manual now.
10781 Fix some bugs when using "$@" when there might be zero positional
10782 arguments in cases where this matters.

10803 that is not portable to Zsh.
10805 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
10807 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
10808 from aclocal.m4 too.
10810 2002-04-12 Akim Demaille <akim@epita.fr>
10812 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
10814 2002-04-10 Akim Demaille <akim@epita.fr>
10816 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
10817 workaround for ${1+"$@"}.
10818 * doc/autoconf.texi (Shell Substitutions): Explain it.
10819 From Oliver Kiddle and Peter Stephenson.
10821 Have M4sh perform minimal shell sanitizing.
10823 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
10824 part into...
10825 (_AS_PREPARE): this new macro.
10826 (AS_PREPARE): New.
10827 (AS_INIT): Invoke AS_SHELL_SANITIZE.
10828 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
10830 Adjust Autoconf and Autotest.
10832 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
10833 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
10834 * lib/autotest/general.m4 (AT_INIT): Likewise.
10835 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10836 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
10837 AS_SHELL_SANITIZE.
10839 Use this M4sh to generate Autoconf's shell scripts.
10841 * tests/wrapsh.as: New, precursor of wrapsh.in.
10842 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
10843 on Autotest and M4sh.
10844 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
10845 (wrapsh.in): New target.
10846 * bin/autoconf.as: New, precursor of autoconf.in.
10847 (autoconf.in): New target.
10849 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
10851 * doc/autoconf.texi (Limitations of Make): Mention the issue
10852 with indented comments in rules.
10854 2002-04-09 Andreas Schwab <schwab@suse.de>
10856 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
10857 ac_top_builddir when setting ac_abs_top_builddir.
10859 2002-04-06 Kevin Ryde <user42@zip.com.au>
10861 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
10862 (Portable Shell): Cross reference to Systemology.
10864 2002-04-05 Akim Demaille <akim@epita.fr>
10866 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
10867 directories when descending in a SUBDIRS.

10870 2002-04-04 Andreas Schwab <schwab@suse.de>
10872 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
10873 contains no literal separators.
10875 2002-04-03 Akim Demaille <akim@epita.fr>
10877 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
10878 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
10879 Use dnl, not the KILL diversion.
10880 Extracted from...
10881 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
10882 (AC_CONFIG_LINKS): here.
10883 Adjust.
10884 Don't use the KILL diversion, as it kills spurious output, which
10885 results in failures being hidden.
10886 Use m4_defn where appropriate.
10887 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
10888 after the second argument.
10889 Use m4_defn.
10890 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
10891 syntax, as it is provided by M4sugar.
10892 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
10894 2002-04-03 Andreas Schwab <schwab@suse.de>
10896 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
10897 expanded if $# <= 2.
10899 * bin/autoreconf.in (autoreconf): Run automake after rerunning
10900 aclocal.

10907 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
10908 (_AC_COMPILER_OBJEXT): Use them.
10909 Fixes Debian #138666.
10911 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
10913 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
10915 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
10916 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
10917 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
10918 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
10919 (AC_C_CONST): Same.
10920 (AC_C_INLINE): Same.
10921 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
10922 * doc/autoconf.texi, NEWS: Document.
10923 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
10924 AC_C_CROSS.
10926 2002-04-02 Akim Demaille <akim@epita.fr>
10928 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
10929 _AS_MKDIR_P_PREPARE.
10931 2002-03-28 Kevin Ryde <user42@zip.com.au>
10933 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
10934 to avoid versions of HP C which don't allow that.
10936 2002-03-27 Paul Eggert <eggert@twinsun.com>
10938 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
10939 (AS_SHELL_SANITIZE): Invoke it.
10940 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
10942 2002-03-26 Akim Demaille <akim@epita.fr>
10944 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
10946 2002-03-26 Akim Demaille <akim@epita.fr>
10948 * doc/autoconf.texi (Introduction): The GNATS base moved.
10950 2002-03-25 Paul Eggert <eggert@twinsun.com>
10952 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
10953 as POSIX requires, as it doesn't work with Zsh.
10954 * doc/autoconf.texi (Assignments): Document the problem.
10956 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
10958 * doc/autoconf.texi (Limitations of Make): Mention more issue
10959 about VPATH, overriding of macros in sub-makes, and handling of
10960 SHELL.
10962 2002-03-21 Paul Eggert <eggert@twinsun.com>
10964 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
10965 problem with here-document buffer boundaries.
10967 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
10968 when reinvoking the shell, to work around problems with installers
10969 who put strange things like "cd" commands in their environments.
10971 2002-03-19 Akim Demaille <akim@epita.fr>
10973 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
10974 From Aaron Ucko.
10976 2002-03-19 Akim Demaille <akim@epita.fr>
10978 * bin/autoscan.in (scan_file): Specify the location in `&used'
10979 invocations.
10980 From Nicolas Joly.
10982 2002-03-19 Akim Demaille <akim@epita.fr>
10984 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
10985 From Nishio Futoshi.
10987 2002-03-19 Akim Demaille <akim@epita.fr>
10989 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
10991 2002-03-18 Paul Eggert <eggert@twinsun.com>
10993 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
10994 (Limitations of Usual Tools): Add mkdir section.
10996 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
10997 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
10998 back on AS_DIRNAME to compute prefixes otherwise; this is
10999 roughly what mkinstalldirs does. That way, we need not have
11000 our own filename disassembler. The old disassembler did not
11001 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
11003 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
11004 Create at_test_all by a series of assignments,
11005 not by a single assignment of a long string. The latter causes ksh
11006 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
11007 presumably because of a buffer overrun.
11009 2002-03-14 Paul Eggert <eggert@twinsun.com>
11011 * lib/autotest/general.m4 (at_times_skip):
11012 Renamed from at_times. Now a boolean.
11013 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
11014 says 'times: not found'.
11016 2002-03-14 Akim Demaille <akim@epita.fr>
11018 * bin/autoreconf.in (&study_gettextize): New.
11019 (&autoreconf): Handle newest gettextize.
11020 Rerun aclocal if needed.
11021 Suggested by Andreas Schwab.
11023 2002-03-13 Akim Demaille <akim@epita.fr>
11025 * doc/autoconf.texi (Special Shell Variables): More about IFS.

11029 * doc/autoconf.texi (Header Portability): New.
11030 Add information about stdint.h and inttypes.h from Paul Eggert.
11032 2002-03-13 Akim Demaille <akim@epita.fr>
11034 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
11035 -p'.
11036 From Bob Proulx.
11038 2002-03-12 Akim Demaille <akim@epita.fr>
11040 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
11041 m4_require.
11043 2002-03-11 Andreas Schwab <schwab@suse.de>
11045 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
11046 does not do it if --with-lispdir is given.
11048 2002-03-08 Akim Demaille <akim@epita.fr>
11050 Version 2.53.
11052 2002-03-08 Akim Demaille <akim@epita.fr>
11054 * doc/autoconf.texi (Subdirectories): Clarify that the
11055 subdirectory should exist.
11057 2002-03-08 Akim Demaille <akim@epita.fr>
11059 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
11061 2002-03-08 Akim Demaille <akim@epita.fr>
11063 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
11064 aliases the actual variables, and modifications of the former
11065 affect the latter.
11067 2002-03-08 Akim Demaille <akim@epita.fr>
11069 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
11070 because of C-c: have m4 output in tmp files, then mv them.
11072 2002-03-08 Akim Demaille <akim@epita.fr>

11087 2002-03-05 Akim Demaille <akim@epita.fr>
11089 Version 2.52i.
11091 2002-03-04 Akim Demaille <akim@epita.fr>
11093 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
11094 * lib/autoconf/general.m4 (AC_INIT): More informative error
11095 message for LIBOBJ.

11099 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
11100 parallel builds.
11102 2002-03-04 Akim Demaille <akim@epita.fr>
11104 * doc/autoconf.texi (Transforming Names): Equality between target
11105 and host is irrelevant.
11106 (Specifying Names, Canonicalizing): Remove all references to the
11107 backward compatibility hooks. Rather, collect them all into...
11108 (Hosts and Cross-Compilation): this new section.
11109 * doc/install.texi (System Type): Ditto.
11110 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
11111 that `--host' implies cross-compilation.
11113 2002-03-04 Akim Demaille <akim@epita.fr>
11115 * doc/autoconf.texi (Evaluation Macros): New.
11116 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
11117 useless.
11118 (_m4_foreach): Define the variant with immediate evaluation so
11119 that it contains exactly the items, not an expression which
11120 evaluation is the current item.
11121 (m4_re_string, m4_re_word): Don't over quote them.
11123 2002-03-04 Akim Demaille <akim@epita.fr>
11125 Instead of having stacking `shift's evaluated at the end, let
11126 `foreach' loops immediately evaluate them.
11128 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
11129 $*. This is the n-th time I change my mind, but hopefully this is
11130 the last...
11131 (m4_lquote): New.
11132 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
11133 efficient.
11134 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
11135 it was only a hack for m4_text_wrap.
11136 (m4_car2): Remove, replaced by...
11137 (m4_cdr): New.
11138 (_m4_foreach): Adjust.
11139 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
11140 m4_bpatsubst for clarification.
11142 2002-03-04 Akim Demaille <akim@epita.fr>
11144 * doc/autoconf.texi (Changequote is Evil): New.

11148 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
11149 on old systems like SunOS.

11173 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
11175 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
11176 translate \r\n to \n.
11178 2002-02-07 Akim Demaille <akim@epita.fr>
11180 Version 2.52h.
11182 2002-02-07 Akim Demaille <akim@epita.fr>
11184 Fix Autoconf PR/209.
11185 Also reported by Frank Denis.

11189 2002-02-07 Akim Demaille <akim@epita.fr>
11191 Fix Autoconf PR/207:
11192 AC_PREFIX_PROGRAM fails with dashed program names
11194 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
11195 variable when looking for the prefix program.
11196 Now it also works for shell variables.
11198 2002-02-07 Akim Demaille <akim@epita.fr>
11200 * doc/autoconf.texi (Limitations of Builtins): More about
11201 case/esac.

11205 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
11206 case/esac, some shells don't support it.
11207 Reported by Zack Weinberg.
11208 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
11210 2002-02-06 Akim Demaille <akim@epita.fr>
11212 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
11213 sure not to introduce newlines in at_groups.
11214 * lib/autotest/Makefile.am (autotest.m4f): Typo.
11216 2002-02-06 Akim Demaille <akim@epita.fr>
11218 * tests/torture.at (Configuring subdirectories): Skip if aclocal
11219 is not available.
11221 2002-02-05 Paul Eggert <eggert@twinsun.com>
11223 * doc/autoconf.texi (Specific Compiler Characteristics):
11224 Describe HP-UX cc bug workaround more accurately.
11225 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
11226 not unsigned long.
11227 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
11228 cross-compilers, too. This undoes some of the most recent change
11229 to this file.
11231 2002-02-05 Akim Demaille <akim@epita.fr>
11233 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
11234 to make sure they are up to date when `check' is run.
11236 2002-02-05 Akim Demaille <akim@epita.fr>
11238 * doc/autoconf.texi (Making testsuite Scripts): Document

11243 * lib/freeze.mk: New.
11245 2002-02-05 Akim Demaille <akim@epita.fr>
11247 Implement `autom4te --freeze'.
11249 * bin/autom4te.in (&freeze): New.
11250 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
11251 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
11253 2002-02-05 Akim Demaille <akim@epita.fr>
11255 * bin/autom4te.in (&parse_args): Implement `frozen files are
11256 optional are the sum of the previous files on the command line'.
11257 Also, pass `--reload-state=' on them, so...
11258 (handle_m4): don't.
11259 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
11260 (M4sh): Rely on M4sugar.
11261 (Autotest, M4sh, M4sugar): Use frozen files.
11263 2002-01-31 Akim Demaille <akim@epita.fr>
11265 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.

11273 2002-01-30 Akim Demaille <akim@epita.fr>
11275 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
11276 for plain code, the other for cross-compilation code. The latter
11277 is now run with GCC only.

11280 2002-01-30 Akim Demaille <akim@epita.fr>
11282 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
11283 values.
11284 * doc/autoconf.texi (Initializing configure): Explain how to
11285 change AC_INIT default values.
11287 2002-01-29 Akim Demaille <akim@epita.fr>

11290 so that aclocal 1.4 works.
11291 Reported by Alexandre Duret-Lutz and Larry Schmitt.
11293 2002-01-28 Akim Demaille <akim@epita.fr>
11295 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
11296 needs an argument.
11298 2002-01-28 Akim Demaille <akim@epita.fr>
11300 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
11301 AUTOTEST_PATH *after* it was set.
11302 Don't put `.' in the PATH: the user should be precise and `./' if
11303 needed. In addition, given that the test suite does some `cd', if
11304 `.' is in the path, the `tested programs' sections will report
11305 programs found in the test suite's directory, while during the
11306 tests (performed in their own directory), these programs are no
11307 longer visible. In other words, the results is confusing and
11308 useless.
11309 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
11311 2002-01-24 Akim Demaille <akim@epita.fr>
11313 Version 2.52g.

11318 * doc/autoconf.texi: Finally add Akim as an author.
11320 2002-01-24 Akim Demaille <akim@epita.fr>
11322 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
11323 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
11324 Bourne. Use /bin/sh.
11325 From Andreas Buening.
11327 2002-01-24 Akim Demaille <akim@epita.fr>
11329 * config/config.guess, config/config.sub, config/texinfo.tex:

11339 Automake.
11341 2002-01-24 Akim Demaille <akim@epita.fr>
11343 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
11344 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
11345 Reported by Geir Ove Myhr.
11347 2002-01-21 Akim Demaille <akim@epita.fr>
11349 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
11351 2002-01-21 Akim Demaille <akim@epita.fr>
11353 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
11354 message on invalid options.
11355 * bin/autom4te.in (parse_args): Don't use
11356 Autoconf::General::getopt with non valid options.
11358 2002-01-17 Jim Meyering <meyering@lucent.com>
11360 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
11361 $ac_cv_exeext so we don't use an old, invalid, cached value.
11363 2002-01-11 Akim Demaille <akim@epita.fr>
11365 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
11366 Meyering.

11368 limitation.
11369 (Particular Functions): Document AC_FUNC_STRNLEN.

11372 2002-01-06 Akim Demaille <akim@epita.fr>
11374 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
11375 package.m4, since is really depends upon configure.ac, not
11376 configure.
11377 * doc/autoconf.texi (testsuite Scripts): Adjust.
11378 * tests/Makefile.am (package.m4): New.
11379 EXTRA_DIST it since its a source.
11381 2002-01-06 Akim Demaille <akim@epita.fr>
11383 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
11384 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
11385 and PACKAGE_BUGREPORT from here...
11386 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
11387 arguments.
11388 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
11389 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
11390 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
11391 * tests/tools.at (autoheader): Adjust.
11392 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
11394 2002-01-06 Akim Demaille <akim@epita.fr>

11398 2002-01-03 Akim Demaille <akim@epita.fr>
11400 * doc/autoconf.texi (Output): Improved wording regarding use of
11401 AC_OUTPUT.
11402 From Olly Betts.
11404 2001-12-18 Kevin Ryde <user42@zip.com.au>
11406 * doc/autoconf.texi (Function Portability): Add notes on sscanf
11407 sometimes needing writable input.
11409 2001-12-17 Jim Meyering <meyering@lucent.com>
11411 * doc/autoconf.texi (New Macros): Tweak wording.
11413 2001-12-14 Akim Demaille <akim@epita.fr>
11415 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
11416 trailing files, don't apply `-rf' to files which might not be
11417 created by configure (core, core.*, and *.core), but just `rm -f'.
11418 Suggested by Jonathan Kamens.
11420 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
11422 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
11424 2001-12-14 Akim Demaille <akim@epita.fr>
11426 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
11428 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
11430 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
11431 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
11432 abs_srcdir, top_srcpath to abs_top_srcdir.

11435 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
11436 * tests/wrappl.in, tests/wrapsh.in: Adjust.
11438 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
11440 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
11441 C/Fortran linking on HP/UX, by extracting the Fortran library
11442 search path from the LPATH line in the $F77 -v output.
11444 2001-12-12 Kevin Ryde <user42@zip.com.au>
11446 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
11447 forbidden file descriptors table.
11449 2001-11-26 Akim Demaille <akim@epita.fr>
11451 * bin/autoscan.in (%c_keywords): Build it at top level.
11452 Map to 1 in order to simplify its uses.
11454 2001-11-26 Akim Demaille <akim@epita.fr>
11456 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
11457 Remove $filepath, useless.
11458 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
11459 variables, they are really part of the tokens.
11460 Split the input line on spaces and then look for tokens.
11461 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
11462 because of `lex$U.$(OBJEXT)'.
11463 (&scan_files): Use "@list" instead of join.
11464 * doc/Makefile.am (CLEANFILES): Add *.fns.
11466 2001-11-26 Akim Demaille <akim@epita.fr>
11468 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
11469 Remove, replaced by...
11470 * tests/wrappl.in: Be common for all the Perl executables.
11471 In particular autoscan and autoheader want -I.
11472 * configure.ac: Adjust.
11473 * lib/autoscan/headers: errno.h is portable.
11475 2001-11-26 Akim Demaille <akim@epita.fr>
11477 * bin/autoscan.in (used): New.
11478 Use it.
11480 2001-11-26 Akim Demaille <akim@epita.fr>
11482 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
11483 directives.
11484 (&scan_sh_file): Remove a duplicate pattern.
11485 (&check_configure_ac): Use long options.

11488 2001-11-26 Akim Demaille <akim@epita.fr>
11490 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
11491 Before, having a line containing the opening of a multi line
11492 comment made the whole line be ignored.
11494 2001-11-26 Akim Demaille <akim@epita.fr>
11496 * doc/autoconf.texi (Using an Autotest Test Suite): New.
11497 (testsuite Scripts): Be one of its subsection.
11498 (Autotest Logs): New.
11500 2001-11-26 Akim Demaille <akim@epita.fr>
11502 Test groups are now run two directories deeper.
11504 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
11505 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
11506 at_top_builddir.
11507 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
11508 top_srcdir, builddir and top_builddir.
11509 Use `at_*dir' relatively to the directory containing the
11510 suite, use `*dir' when relatively to the current group dir.
11512 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
11514 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
11515 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
11516 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
11517 spelling errors.
11519 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
11521 * doc/autoconf.texi (Using System Type): Add an example of `case
11522 $host' usage so people quit using `case $target' everywhere.
11524 2001-11-22 Akim Demaille <akim@epita.fr>
11526 * doc/autoconf.texi (Installation Directory Variables): Englishoes
11527 spotted by Jim Meyering.
11529 2001-11-16 Paul Eggert <eggert@twinsun.com>
11531 This patch implements a `long double' suggestion by Oliver Kiddle.
11533 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
11534 static, to catch errors if the value isn't known at compile-time
11535 and the compiler supports dynamic arrays. Change its name from
11536 `_array_' to `test_array' to avoid potential name clashes.
11537 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
11538 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
11539 better than double. Catch a bug in GCC 2.95.2 x86.
11540 * doc/autoconf.texi (C Compiler): Document the above.
11541 * NEWS: Likewise.
11543 2001-11-13 Akim Demaille <akim@epita.fr>
11545 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
11546 hand.
11547 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
11549 2001-11-13 Akim Demaille <akim@epita.fr>
11551 * lib/autotest/general.m4 (AT_INIT): After having run the test
11552 group, go back to the initial directory, not to at_suite_dir.
11554 2001-11-13 Akim Demaille <akim@epita.fr>
11556 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
11557 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
11558 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
11559 option.
11560 (AT_CHECK_CONFIGURE): Use absolute paths.
11561 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
11562 The problem is still the old one: there is no means in M4 (that I
11563 know about) to create a defining macro, because there is no means
11564 to create `$1' etc., therefore, the defining macro ``swallows''
11565 all the arguments meant to the defined macro.
11567 2001-11-13 Akim Demaille <akim@epita.fr>
11569 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
11570 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
11571 configure.ac.
11572 * tests/aclocal.m4: Remove, as it is no longer used.
11574 2001-11-13 Akim Demaille <akim@epita.fr>
11576 * lib/autotest/general.m4: Change `tests?' into `groups?' in
11577 variable names when referring to a single test group, or to
11578 `suite' when referring to the whole test suite.
11579 `at_last_test' is removed: m4 compute at_format itself.
11580 (at_stdout, at_stder1, at_stderr): New variables.
11581 (AT_CHECK): Use them.
11583 2001-11-13 Akim Demaille <akim@epita.fr>
11585 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
11586 in PATH.
11587 Create `testsuite.dir/003/run' instead of `testsuite.003'.
11588 Do it as soon as a test fails, don't wait till the end of the test
11589 suite.
11590 Don't remove $as_me.[0-9]*, since these files no longer exist.
11592 2001-11-13 Akim Demaille <akim@epita.fr>
11594 * tests/tools.at: Use absolute paths, since we are no longer run
11595 in place.
11597 2001-11-13 Akim Demaille <akim@epita.fr>
11599 Now that tests are running in their own private dir, there is no
11600 need to list the files to remove at the end of tests groups.
11602 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
11603 (AT_data_files, at_data_files): Remove.
11604 (AT_CLEANUP, AT_DATA): Simplify.
11605 (AT_INIT): Adjust.
11606 Remove the group dir if !debug && !failed.
11607 * tests/atspecific.m4: Adjust.
11609 2001-11-13 Akim Demaille <akim@epita.fr>
11611 Start a new layout for Autotest: `testsuite' creates
11612 `testsuite.dir' in which the at-check-line etc. files are to be
11613 found, and `testsuite.dir/003' where the test group 3 is run.
11615 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
11616 at_check_line_file, at_format, at_test_normalized, at_group_dir
11617 are new variables.
11618 Create the directories.
11619 Use absolute paths for at- files.
11620 (AT_CHECK): Adjust.
11622 2001-11-11 Michael Matz <matz@kde.org>
11624 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
11625 (m4_car2): New.
11626 (m4_car): Properly quote arguments.
11628 2001-11-13 Akim Demaille <akim@epita.fr>
11630 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
11631 with stricter rules on LIBOBJS.
11633 2001-11-12 Paul Eggert <eggert@twinsun.com>
11635 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
11636 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
11637 __PROTOTYPES too.
11639 2001-11-12 Akim Demaille <akim@epita.fr>
11641 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
11643 2001-11-12 Akim Demaille <akim@epita.fr>
11645 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
11646 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
11647 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11648 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
11649 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
11650 specify to what the macro should be defined (typically to 1).
11652 2001-11-12 Akim Demaille <akim@epita.fr>
11654 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
11655 From Jim Meyering.
11657 2001-11-12 Akim Demaille <akim@epita.fr>
11659 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11660 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
11661 definition used by Automake where LEX is +/- "${missing} lex" and
11662 `missing' itself contains variables.
11664 2001-11-12 Akim Demaille <akim@epita.fr>
11666 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
11667 Now that M4sh pushes BODY, the comments were output at the end of
11668 the test suites.
11670 2001-11-08 Akim Demaille <akim@epita.fr>
11672 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
11673 that we can trace macros from aclocal.m4.
11674 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
11675 obsoleted, and redirect to the former anyway.
11676 Reported by Ralf Corsepius.
11678 2001-11-08 Akim Demaille <akim@epita.fr>
11680 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
11681 processed only if present.
11682 * tests/torture.at (Configuring subdirectories): Use autoreconf
11683 instead of successive calls to autoconf.
11684 Add a nonexistent subdirectory to exercise the patch above.
11685 Reported by Ralf Corsepius.
11687 2001-11-08 Kevin Ryde <user42@zip.com.au>
11689 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
11690 doesn't accept .S files.
11692 2001-11-07 Akim Demaille <akim@epita.fr>
11694 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.

11696 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
11697 * bin/autom4te.in (warn_forbidden): New.
11698 (handle_output): Use it.
11699 Read m4_pattern_forbid with messages.
11701 2001-11-05 Akim Demaille <akim@epita.fr>
11703 * bin/autom4te.in (--normalize): Remove.
11704 * lib/autom4te.in: Adjust.
11706 2001-11-05 Akim Demaille <akim@epita.fr>
11708 * tests/Makefile.am (testsuite): Rename this target as...
11709 ($(TESTSUITE)): this.
11710 From Nicolas Joly.
11712 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
11714 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
11715 the --prefix option, also remove it's argument.
11717 2001-11-05 Akim Demaille <akim@epita.fr>
11719 * doc/autoconf.texi (testsuite Invocation): Update.
11720 (Writing testsuite.at): Update.
11722 2001-11-03 Akim Demaille <akim@epita.fr>
11724 * doc/autoconf.texi: s/@code/@command/ where appropriate.
11726 2001-11-03 Akim Demaille <akim@epita.fr>
11728 * lib/Autom4te/General.pm: (&catfile, &canonfile)
11729 (&file_name_is_absolute): New, wrappers around routines from
11730 File::Spec.
11731 Use and export them.
11732 (&find_configure_ac): Optionally take a directory where to look at.
11733 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
11734 the arguments.
11735 Default @ARGV to `.', not find_configure_ac.
11736 (&autoreconf): Argument is a directory.
11737 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
11738 * doc/autoconf.texi (autoreconf Invocation): Update.
11740 2001-11-03 Akim Demaille <akim@epita.fr>
11742 * lib/Autom4te/General.pm (@export_vars, @export_subs)
11743 (@export_forward_subs): New.
11744 Add basename, dirname, and fileparse.
11745 (@EXPORT): Adjust.
11746 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
11747 Don't look for aclocal flags if we already know aclocal is not
11748 used.
11749 Move aclocal.m4t only if it exists.
11750 Reported by Ezra Peisach.
11752 2001-11-03 Akim Demaille <akim@epita.fr>
11754 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
11755 passed on command line, defaulting to ./configure.ac if present.
11756 (&maybe_autoreconf, File::Find): Remove, unused.
11757 (&autoreconf): If autoconf is not used, don't try to trace.
11759 2001-11-02 Akim Demaille <akim@epita.fr>
11761 * configure.ac: Bump to 2.52g.
11763 2001-11-02 Akim Demaille <akim@epita.fr>
11765 Version 2.52f.
11767 2001-11-02 Akim Demaille <akim@epita.fr>
11769 * config/config.guess, config/config.sub, doc/standards.texi:
11770 * config/lispdir.m4: Update from masters.
11771 * configure.ac: Bump to 2.52f.
11773 2001-11-02 Akim Demaille <akim@epita.fr>
11775 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
11776 Don't run aclocal when aclocal.m4 is not from aclocal.
11777 From Ezra Peisach.
11778 Don't run libtoolize and gettextize if --install is not given.
11780 2001-11-01 Paul Eggert <eggert@twinsun.com>
11782 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
11783 be invoked before _AS_LINENO_PREPARE.
11784 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
11785 than character ranges.
11787 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
11788 invoking AS_BASENAME. Set the locale variables to 'C' if
11789 possible, as POSIX requires this to get the traditional
11790 behavior.
11791 * doc/autoconf.texi (Special Shell Variables): Describe the above.
11793 2001-10-31 Paul Eggert <eggert@twinsun.com>
11795 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
11796 with {}, as that triggers a bug in Bash 2.05.
11798 (_AS_LINENO_PREPARE): Use Sed rather than
11799 Awk. Fix the sed prepass to work even if there are multiple
11800 instances of $LINENO on the same line. Do not substitute for
11801 other variables like $LINENOT. Do not check file dates; such a
11802 check is unreliable on sufficiently fast machines, and removing
11803 the check makes the code simpler and more reliable. Check for
11804 output and chmod failures.
11806 * doc/autoconf.texi (Special Shell Variables): Document
11807 the above.
11809 2001-10-31 Akim Demaille <akim@epita.fr>
11811 * tests/Makefile.am (atconfig): Remove this target, Automake
11812 handles it now.
11814 2001-10-31 Akim Demaille <akim@epita.fr>
11816 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
11817 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
11818 provided, while it is optional.
11819 * configure.ac: Adjust.
11821 2001-10-26 Paul Eggert <eggert@twinsun.com>
11823 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
11824 lib/Autom4te/Struct.pm:
11825 Require Perl 5.005_03 instead of just 5.005, as some tests fail
11826 with 5.005_02.
11828 * doc/autoconf.texi (Special Shell Variables): Document some
11829 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
11831 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
11832 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
11833 eval $LINENO is not portable in practice.
11835 2001-10-24 Akim Demaille <akim@epita.fr>
11837 * lib/Autom4te/General.pm (backname): New.
11839 2001-10-24 Akim Demaille <akim@epita.fr>
11841 * m4/: Remove, merged into...
11842 * config/: here.
11844 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
11846 * doc/autoconf.texi (Shellology): Mention the problems with bash
11847 2.05's use of ANSI quoting in its `set' builtin.
11849 2001-10-22 Paul Eggert <eggert@twinsun.com>
11851 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
11852 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
11853 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
11854 POSIX decided to standardize on the int flavor of strerror_r.
11855 Always do char* test, as there's no reason not to.
11856 Assign to a char* var, to catch strerror_r that returns int*.
11858 * doc/autoconf.texi (Particular Functions):
11859 Document the above changes. Also, document the fact that
11860 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
11862 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
11864 2001-10-20 Akim Demaille <akim@epita.fr>
11866 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
11867 the executable was missing from the log.

11871 * lib/Autom4te/General.pm (&update_file): If destination is
11872 unchanged, remove the source.
11873 (&up_to_date_p): Don't be verbose, be debug.
11874 * bin/autoreconf.in: No longer support --m4dir.
11875 (&autoreconf): Display the full path of the configure.ac we are
11876 studying.
11877 Trace it only once.
11878 Be sure to honor --force with gettextize.
11879 Always run aclocal.
11880 * doc/autoconf.texi: Adjust.
11882 2001-10-20 Akim Demaille <akim@epita.fr>
11884 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
11885 Remove, dead.
11886 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
11887 `intl' is already present, as it refuses unless --force.
11888 (&parse_args): Use -I, --include instead of the old Autoconf
11889 options.
11890 ($localdir, $autoconf_dir): Remove.
11891 (@include): New.
11892 (&maybe_autoreconf): New, to preserve $_ for File::Find.
11894 2001-10-19 Jens Petersen <petersen@redhat.com>
11896 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

11901 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
11902 file in @configure_input@.
11903 Don't mention `automatically' in addition to `generated'.
11904 * tests/torture.at (#define header templates): Adjust.
11906 2001-10-19 Akim Demaille <akim@epita.fr>
11908 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
11909 comment, explain how to install automatic mode selection.
11910 From Russ Allbery.
11912 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
11914 * bin/autoreconf.in (autoreconf): Display the path to the
11915 configure.ac being studied.
11917 2001-10-18 Paul Eggert <eggert@twinsun.com>
11919 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
11920 long, to work around a bug in the HP C compiler version HP92453-01
11921 B.11.11.23709.GP.
11923 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
11924 (AS_BASENAME_EXPR): New macro.
11925 (AS_BASENAME_SED): Do not assume GNU sed semantics.
11926 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
11927 and fall back on 'sed' only if the other two fail. This makes
11928 AS_BASENAME act more like AS_DIRNAME.
11929 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
11930 contains white space.
11931 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
11932 Use AS_DIRNAME, since I think it's now DOS-friendly.
11933 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
11934 Allow "dirname //FOO" to return either / or //, as POSIX allows
11935 either behavior.
11937 2001-10-10 Akim Demaille <akim@epita.fr>
11939 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
11940 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
11941 From Eric Sharkey.

11945 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

11966 (&parse_args): Pass verbosity/debugging options to subtools when
11967 --debug, not when --verbose.
11968 * lib/autom4te.in (Autoreconf-preselections): New.
11969 (Autoconf): Use it.

12036 * lib/autoconf/general.m4 (AS_DEFUN, AC_DEFUN_ONCE, AC_BEFORE)
12037 (AC_REQUIRE, AC_PROVIDE, AC_PROVIDE_IFELSE): Be exact copy of the
12038 M4sugar peer, i.e., drop the `AC_PROVIDE_$1' broken marker.
12040 2001-10-08 Akim Demaille <akim@epita.fr>
12042 Use `add-log-current-defun-function' for ChangeLog creation.
12043 Suggested by Tom Tromey.
12045 * lib/emacs/autotest-mode.el (autotest-mode-map): New.
12046 (autotest-mode): Adjust.
12047 * lib/emacs/autoconf-mode.el (autoconf-mode-map): Modernize, map

12053 2001-10-08 Akim Demaille <akim@epita.fr>
12055 * lib/autoconf/general.m4 (_m4_divert(BODY)): Move to...
12056 * lib/m4sugar/m4sh.m4: here.
12057 (AS_INIT): Push the BODY diversion, set the #! /bin/sh line.
12058 * lib/autoconf/general.m4 (AC_PLAIN_SCRIPT) : Remove.
12059 (AT_INIT): Replace AC_PLAIN_SCRIPT with AS_INIT invocation,
12060 include handle the m4_pattern_*, no longer push the
12061 BODY diversion nor set the /bin/sh line, AS_INIT does it.
12062 * lib/autotest/general.m4 (AT_INIT): Likewise.
12063 * tests/base.at: Adjust the tests to use AS_INIT.
12064 * tests/tools.at (AT_DATA_FORBIDDEN): New.

12070 * doc/autoconf.texi (config.status Invocation):
12071 CONFIG_SHELL defaults to a shell that supports LINENO if available.

12074 shell does not support LINENO, and if CONFIG_SHELL is unset or
12075 empty, and if we can find a shell that does support LINENO,
12076 then set CONFIG_SHELL to that shell and then re-execute
12077 ourselves with CONFIG_SHELL.
12079 2001-10-05 Paul Eggert <eggert@twinsun.com>
12081 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
12082 doesn't exist. Remove *.tmp, as a .tmp file is created during the
12083 build of $(TESTSUITE).
12085 2001-10-05 Akim Demaille <akim@epita.fr>
12087 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

12096 Fix the absolute path case/esac pattern.
12097 Provide $0 as fallback for as_myself.
12098 Reported by Raja R Harinath.

12105 2001-10-05 Akim Demaille <akim@epita.fr>
12107 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): New, extracted from...
12108 (AS_SHELL_SANITIZE): here. Use it.
12109 (_AS_LINENO_PREPARE): Preserve the exit status of $0.lineno.
12110 From Paul Eggert.
12112 2001-10-04 Akim Demaille <akim@epita.fr>
12114 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable
12115 combination of Awk and sed to replace $LINENO.
12117 2001-10-02 Paul Eggert <eggert@twinsun.com>
12119 * doc/autoconf.texi (Limitations of Builtins): You can't use
12120 "source"; it's not portable. Remove confusing and
12121 somewhat-incorrect example involving "." and "/".
12123 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
12124 compatibility with POSIX shells.
12126 2001-10-02 Akim Demaille <akim@epita.fr>
12128 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
12129 instead of exec'ing to preserve $0 and $@.
12131 2001-10-01 Akim Demaille <akim@epita.fr>
12133 * tests/testsuite (AT_INIT) <at_pass_list>: New.
12134 Don't run twice the same test.
12136 2001-10-01 Akim Demaille <akim@epita.fr>
12138 * lib/autotest/general.m4 (AT_INIT) <--help>: Catch up with reality.
12139 No longer output the list of tests.

12143 Various small adjustments.
12145 2001-10-01 Akim Demaille <akim@epita.fr>
12147 * doc/autoconf.texi: Use @kbd for user input.

12152 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
12153 Don't use nested parenthesization. This patch was originally
12154 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
12155 but somehow it didn't get incorporated then.
12156 * doc/autoconf.texi (Limitations of Usual Tools):
12157 Clarify remark about sed and nested parenthesization.
12159 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
12160 Report an error if the size cannot be determined even though
12161 the type exists.
12162 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
12163 Check for `expr' arithmetic overflow, and for compilation failure,
12164 and invoke a new argument $4 if either is discovered.
12165 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
12166 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
12168 2001-09-28 Akim Demaille <akim@epita.fr>

12180 Catch unexpanded PACKAGE_STRING and PACKAGE_BUGREPORT.
12182 2001-09-27 Akim Demaille <akim@epita.fr>
12184 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
12185 generates too many bug reports.
12187 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
12188 status when executing the ACTION-IF-FALSE.
12189 * tests/base.at (AC_TRY_*): Rename as...

12196 * tests/c.at (Extensions, C keywords)
12197 (Broken/missing compilers, AC_PROG_CPP with warnings)
12198 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
12199 (AC_PROG_CPP requires AC_PROG_CC): here and...
12200 * tests/fortran.at (GNU Fortran 77): there.
12201 * doc/autoconf.texi (autoconf Invocation): Fix the example:
12202 AC_TRY_RUN is about compilation, not shell commands.
12203 (Test Programs): AC_TRY_RUN works as used to be advertised.
12205 2001-09-27 Akim Demaille <akim@epita.fr>
12207 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
12208 Raja R Harinath:
12209 Be sure to detect when $LINENO always returns the same value.
12210 Look for the original script, basename($0) is certainly not
12211 enough.
12212 Pass the CLI arguments to `$as_me.lineno'.
12214 2001-09-25 Akim Demaille <akim@epita.fr>
12216 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

12228 * doc/autoconf.texi (Top): Wrap in @ifnottex.
12230 2001-09-23 Akim Demaille <akim@epita.fr>
12232 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
12233 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
12234 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
12235 builddir, buildpath, top_builddir, and top_buildpath.
12236 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
12237 the current directory.
12238 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
12239 variables *before* changing the current directory.
12240 Skip nonexistent dirs.

12242 variables.
12244 * lib/autotest/general.m4: Do not reset AT_victims.
12245 Don't compute at_srcdir nor at_top_srcdir.
12247 * tests/tools.at: Hence use top_srcdir.
12249 * tests/Makefile.am, tests/autoconf, tests/autoheader,
12250 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
12251 Remove.
12252 * tests/autoreconf.in, tests/wrappl.in, tests/autom4te.in,
12253 * tests/wrapsh.in, tests/autoupdate.in: New.
12254 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
12255 * configure.ac: Build the position independent wrappers.
12257 * man/Makefile.am: Now that test wrappers are position
12258 independent, use them and drop dark envvar magic.
12260 2001-09-23 Akim Demaille <akim@epita.fr>
12262 * doc/autoconf.texi (Common Shell Constructs): Rename as...
12263 (Programming in M4sh): this.
12264 Promote to @section.
12266 2001-09-23 Akim Demaille <akim@epita.fr>
12268 * lib/autotest/general.m4 (AT_INIT): Dump config.log last.

12280 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix shell
12281 over-escaping.

12291 (Autoconf): Adjust.
12293 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
12295 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,
12296 * m4/install-sh.m4, m4/missing.m4, m4/sanity.m4, m4/strip.m4: Updated
12297 to match current versions from CVS Automake.

12302 for $LINENO.
12304 2001-09-22 Akim Demaille <akim@epita.fr>
12306 * lib/autoconf/autotest.m4: Create `package.m4'.
12307 * tests/Makefile.am (package.m4): Remove.
12309 2001-09-22 Akim Demaille <akim@epita.fr>
12311 Rely on `$LINENO' when possible instead of `__oline__'.
12313 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
12314 `$LINENO' support replacement when not supported.
12315 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
12316 them explicitly to be sure they are not output before this section
12317 (via m4_require). Cosmetic only.
12318 * lib/autoconf/c.m4, lib/autoconf/general.m4,
12319 * lib/autoconf/programs.m4: Replace all the occurrences of
12320 `__oline__' with `$LINENO'.
12321 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
12323 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
12325 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
12326 character (u: -> ue) in a code comment.
12327 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
12328 it works.
12330 2001-09-21 Akim Demaille <akim@epita.fr>
12332 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
12333 Suggested by Jim Meyering.
12335 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12337 * lib/autoconf/programs.m4: Use extensions listed in
12338 $ac_executable_extensions when looking for programs.
12340 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12342 * lib/autoconf/general.m4: Fix a small Englisho.
12343 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
12344 setting up ac_dir_suffix and ac_top_builddir.
12345 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
12347 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12349 * doc/autoconf.texi (File System Conventions): Clarify the use of
12350 PATH_SEPARATOR.
12351 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
12352 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
12353 be used instead of ':'.
12354 * lib/autotest/general.m4: Replace occurrences of ':' in
12355 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
12357 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12359 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
12360 arguments. Fixed a typo.
12362 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12364 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
12365 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
12367 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12369 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
12370 * bin/autoupdate.in: Ditto.
12371 * bin/autoheader.in: Reworded a few comments.
12372 * bin/autoconf.in: Reworded help text for a few options.
12373 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
12374 * bin/autoscan.in, bin/autoupdate.in: Ditto.
12376 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12378 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
12379 already have $file). Set output files to binary mode (helps avoid
12380 CR issues on DOSish systems).
12382 2001-09-19 Akim Demaille <akim@epita.fr>
12384 * lib/autotest/general.m4: Englishoes.
12385 From Tim Van Holder and Alexey Mahotkin.
12387 2001-09-18 Paul Eggert <eggert@twinsun.com>
12389 * doc/autoconf.texi (Common Shell Constructs): New node,
12390 documenting AS_DIRNAME.
12391 (Limitations of Usual Tools): Refer to it when discussing dirname.
12392 Also, update discussion of POSIX standard to reflect latest draft.
12394 * lib/autoconf/c.m4:
12395 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
12397 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
12398 Do not pass a first argument with leading '-'
12399 to expr, by parenthesizing initial integers that might be negative.
12401 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
12402 now merely checks whether it is an error to pass an argument
12403 to getpgrp.
12405 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
12406 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
12407 whether it is a (compile-time) error to pass an argument to
12408 getpgrp. This simpler test supports the revised documentation,
12409 and is all that AC_FUNC_GETPGRP's users really need.
12411 2001-09-18 Akim Demaille <akim@epita.fr>
12413 * doc/autoconf.texi (Limitations of Make) <$<>: New.
12415 2001-09-18 Akim Demaille <akim@epita.fr>
12417 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
12418 `{}'.
12419 * lib/autotest/general.m4 (AT_INIT): Adjust.
12421 2001-09-18 Paul Wagland <paul@wagland.net>
12423 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
12424 correctly.
12425 Add test for AS_BASENAME.
12426 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
12427 added test. It now correctly handles /1/2/3/, returning '3' not ''.
12428 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
12429 * tests/base.at: Fixed the expected responses. The old ones were
12430 one line out...
12431 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
12432 the documentation claims it should (and how it behaved in 2.13).
12434 2001-09-18 Akim Demaille <akim@epita.fr>
12436 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
12437 the AC_CONFIG_COMMANDS invocation.
12438 This also solves the name clash problems.
12439 Don't set the package's ID.
12440 * lib/m4sugar/Makefile.am (version.m4): Revamp.
12441 No longer to be shipped.
12442 (version.in): Remove.
12443 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
12444 * lib/autoconf/status.m4: Adjust.
12445 Use `m4_PACKAGE_STRING'.
12446 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
12447 the only optional argument is the name of the test suite.
12448 Expect `package.m4' to define the package signature.
12449 * lib/autom4te.in (Autotest): Add `package.m4?'.
12450 * tests/Makefile.am (package.m4): New.
12451 * tests/suite.at: ifnames is a victim.
12453 2001-09-18 Akim Demaille <akim@epita.fr>
12455 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
12456 AC_LIBSOURCE, AC_CONFIG_FILES.
12457 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
12458 program version string doesn't match the package's.
12459 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
12460 after `(cached)'.
12462 2001-09-17 Paul Eggert <eggert@twinsun.com>
12464 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12465 Allow expression to return any value that can fit into unsigned long
12466 (not int, as before). Check for output errors.
12468 2001-09-17 Bruno Haible <haible@ilog.fr>
12470 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12471 Always include <stdio.h> and <stdlib.h>. Evaluate
12472 the expression in an extra function before these includes. Call
12473 fprintf "%d" only after ensuring the argument is of type 'int'.
12474 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
12476 2001-09-17 Paul Eggert <eggert@twinsun.com>
12478 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
12479 or CFLAGS=-O5. In that case, the linker has a relaxed view of
12480 fatal errors, and AC_CHECK_LIB causes it to include libraries even
12481 when they don't exist.
12483 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,

12488 version with the version used by fileutils 4.1, except use

12646 2001-09-05 Akim Demaille <akim@epita.fr>
12648 Be ready to handle filenames as stupid as `dnl.at', for if even
12649 the maintainer is dumb enough to do that...
12651 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
12652 excellence in M4 quotation: consider `__file__' is active.
12654 And BTW, when invoking m4, pass the --include in the right order:
12655 the wrong one.
12657 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
12658 4m.

12685 New, extracted from main.
12686 Use IO::File wherever possible.
12687 (input.m4): Be constant, use -I instead of hard coding $tmp.
12688 Therefore be a quoted heredoc.
12689 Don't invoke `_au_disable', since ac was not loaded, but just
12690 `unm4.m4'.
12692 2001-08-31 Akim Demaille <akim@epita.fr>
12694 Version 2.52d.

12719 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
12720 (testsuite Scripts): There is no such thing as `atconfig.in'.
12721 And actually one diagram is missing: test suite runtime.
12723 2001-08-31 Akim Demaille <akim@epita.fr>
12725 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
12726 inverse order.
12728 2001-08-31 Akim Demaille <akim@epita.fr>
12730 * bin/autoupdate.in (@include): `installcheck' revealed the path
12731 to m4sugar was lacking!
12733 2001-08-31 Akim Demaille <akim@epita.fr>
12735 * man/Makefile.am (.x.1): We really have to pass
12736 autom4te_perllibdir.
12738 2001-08-31 Akim Demaille <akim@epita.fr>
12740 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

12746 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
12747 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
12748 Use directly autom4te, not autoconf.

12773 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
12774 (autoheader): Pass --force since the test suite goes too fast for
12775 the time stamps.
12776 Adjust to the new autoheader messages.
12778 2001-08-31 Akim Demaille <akim@epita.fr>
12780 * bin/autoheader.in: Handle the acconfig.h etc. junk files.

12792 `autoheader: `config.hin' is created'.
12793 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
12795 2001-08-31 Akim Demaille <akim@epita.fr>
12797 * bin/autoheader.in: Rewrite in Perl.

12800 2001-08-31 Akim Demaille <akim@epita.fr>

12803 Map --localdir, --autoconf-dir onto it.
12804 Forward autom4te's options instead of interpreting them.
12805 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
12806 There is no such envvar since the inception of autom4te.cfg.
12807 * bin/autom4te.in (&parse_args): Uniquify `@include'.
12808 * bin/autoupdate.in: Adjust, and perform more control.

12815 * bin/autom4te.in (&find_file): Support `FILE?' standing for
12816 optionally `FILE'.

12819 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
12821 2001-08-31 Akim Demaille <akim@epita.fr>
12823 * configure.ac: Also find tested executables in bin.
12824 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
12825 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
12826 installed peer executables, only PATH is allowed to resolve it.
12827 Pass `autoconf_dir' via options, not via invisible envvars.
12828 * lib/Autom4te/General.pm (&find_peer): Remove.
12829 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
12830 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
12831 * man/Makefile.am: Let help2man rely on PATH instead of trying to
12832 find the executables for it.
12833 * tests/Makefile.am: Major cleanup. Too lazy to document...
12834 * tests/atlocal.in: Remove all the obscure envvar manipulations.
12835 We only need PERL.
12836 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
12837 indeed related to running the test suite, while passing
12838 --autoconf-dir and others is related to running non installed
12839 Autoconf executables. So don't do that, leave it to...
12840 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
12841 * tests/autoscan: New.
12842 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
12843 refer to library files: rely on --language.

12847 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

12856 2001-08-29 Akim Demaille <akim@epita.fr>
12858 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
12859 Suggested by Paul Eggert.
12861 2001-08-29 Akim Demaille <akim@epita.fr>
12863 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
12864 download in a tmp dir.
12866 2001-08-29 Akim Demaille <akim@epita.fr>
12868 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

12891 (at-devnull): Rename as...
12892 (AT-devnull): this.
12893 (--clean): Remove AT-* files too.

12929 * lib/autotest/general.m4 (AT_INIT): Log the command line.

13401 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
13403 * tests/semantics.at (AC_C_BIGENDIAN): New test.
13405 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
13407 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
13408 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
13409 * doc/autoconf.texi (C Compiler Characteristics): Update
13410 documentation for AC_C_BIGENDIAN.
13412 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
13414 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
13415 magic values from an object file when cross-compiling.
13416 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
13418 2001-08-10 Akim Demaille <akim@epita.fr>
13420 * bin/autom4te.in (&handle_output): Don't use `grep' with side
13421 effects.
13422 Suggested by Russ Allbery.
13424 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
13426 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
13427 current $prefix to the sub-configures.
13429 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
13431 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
13432 extension (needed on BeOS). Reported by Guido van Rossum.
13434 2001-08-09 Akim Demaille <akim@epita.fr>
13436 * bin/autom4te.in ($icache): Load it only if older than autom4te.
13438 2001-08-07 Akim Demaille <akim@epita.fr>
13440 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
13441 removed.
13442 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
13443 No need to remove the files before and after the each test, before
13444 each test and at the end of the suite is enough.
13445 Display only the children `times', not the shell's.
13446 If the test failed or was skipped, at-times is not available.
13448 2001-08-07 Akim Demaille <akim@epita.fr>
13450 Always produce testsuite.log, including when there are no
13451 failures. This helps getting information on skipped tests, and
13452 duration of the tests. Err, implement the latter btw.
13454 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
13455 Dump information on the first run of each test.
13456 (AT_CLEANUP): Create `at-times' containing the duration of the
13457 test group.
13459 2001-08-07 Akim Demaille <akim@epita.fr>
13461 The use of `dumpstat' revealed that `len' was used although it
13462 should not. m4_text_wrap was using it, but in the Autoconf world
13463 where it is legal. Hence (i) test M4sh in its own world, not
13464 Autoconf's, and (ii), ahem, fix the bug :)
13466 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
13467 does not like `' instead of [].
13468 (AT_INIT): Forbid `^_?AT_'.
13469 And don't output such tokens.
13470 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
13471 `script.as', and `autom4te.cache'.
13472 Remove `empty' and `macro' which are no longer used.
13473 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
13474 * tests/m4sugar.at: Use it.
13475 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
13477 2001-08-07 Akim Demaille <akim@epita.fr>
13479 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
13481 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
13483 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
13485 2001-08-04 Akim Demaille <akim@epita.fr>
13487 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
13488 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
13489 AC_TRY_LINK.
13490 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
13491 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
13492 (AC_F77_MAIN): Likewise.
13494 2001-08-04 Akim Demaille <akim@epita.fr>
13496 Don't rely on M4sugar outputting the patterns in files, since we
13497 might process the output _without_ running m4, hence without these
13498 files.
13500 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
13501 * bin/autom4te.in (@Request::includes): Remove, unused.
13502 (@Request::source): Rename as...
13503 (@Request::input): this.
13504 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
13505 (&handle_output): Fetch the patterns from the traces.
13506 `$forbidden' and `$allowed' are constant: use m//o.
13507 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
13508 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
13510 2001-08-04 Akim Demaille <akim@epita.fr>
13512 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
13513 autoconf', i.e., in addition to caching traces, cache the output.
13515 * bin/autom4te.in (Request::cache): Rename as...
13516 (Request::id): this.
13517 ($cache, $icache, $tcache, $ocache): New.
13518 (&handle_m4): Save M4 output in the cache instead of $tmp.
13519 (&handle_output): Adjust.
13520 (&up_to_date_p): Check that the output cache is up to date too.
13521 (top level): Run `&handle_m4' iff force or the cache is invalid.
13522 Run `&handle_output' if the output cache is more recent.
13524 2001-08-04 Akim Demaille <akim@epita.fr>
13526 * bin/autom4te.in ($force): New.
13527 (&parse_args, &print_usage): -f, --force is a new option.
13528 (&handle_output): CPP directives might have spaces after `#'.
13529 (&parse_args): The first file only can be frozen.
13531 2001-08-04 Akim Demaille <akim@epita.fr>
13533 Don't let autom4te compute the `include' traces several times:
13534 first check that the trace cache file is up to date, and then
13535 compare its timestamp with that of the output.
13537 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
13538 the preamble. Don't require 5.005 as Autom4te::General does it,
13539 and better yet (use `use', not `require'!).
13540 * lib/Autom4te/Struct.pm: Rename the last occurrences of
13541 Class::Struct as Autom4te::Struct.
13542 * lib/Autom4te/General.pm (File::stat): Use it.
13543 (&mtime): New, export it.
13544 * bin/autom4te.in: Use it.
13545 Declare `$req' is invalid if it is outdated.
13546 Don't declare it valid before saving it if something went wrong.
13548 2001-08-04 Akim Demaille <akim@epita.fr>
13550 Autom4te shall not encode Autoconf data, and preselecting traces
13551 must be proposed to the users.
13553 * bin/autom4te.in (@required_trace): Remove.
13554 (@preselect): New.
13555 (&parse_args, &print_usage): -p, --preselect is a new option.
13556 (&up_to_date_p): Adjust.
13557 * bin/autoconf.in: Preselect some Autoconf macros.
13559 2001-08-04 Akim Demaille <akim@epita.fr>
13561 * tests/tools.at (autoconf --trace: user macros): Check traces on
13562 macros invoked without arguments, and macros invoked with multiple
13563 lines arguments.
13565 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
13567 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
13568 arguments.
13570 2001-08-03 Akim Demaille <akim@epita.fr>
13572 * bin/autoconf.in ($@): Work around the usual sh bug.
13573 From Nicolas Joly.
13575 2001-08-03 Akim Demaille <akim@epita.fr>
13577 Clean up the handling of the M4 builtins tracing exception.
13579 * bin/autom4te.in (Request::request): Don't complete M4 builtins
13580 trace requests.
13581 (@m4_builtins): Rename as...
13582 (@m4_builtin): this.
13583 (%m4_builtin_alternate_name): New.
13584 (&parse_args): Complete the trace requests with alternate names.
13585 (&handle_traces): Hence no longer do it here.
13586 (&trace_requests): Remove, unused.
13588 2001-08-03 Akim Demaille <akim@epita.fr>
13590 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
13591 m4_if, and m4_wrap.
13593 2001-08-03 Akim Demaille <akim@epita.fr>
13595 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
13596 (m4_divert_pop): Dump the whole diversion stack when a diversion
13597 mismatch happens.
13598 * bin/autom4te.in (&handle_output): Remember of the first
13599 occurrence of a possibly undefined macro, not the last.
13600 Complain about the possibly undefined macros in the same order as
13601 the appear in the output.
13602 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
13603 * tests/tools.at (autoconf: forbidden tokens, basic)

13605 autoconf's stderr, as it is now deterministic.
13606 Check that `dnl' is caught.
13608 2001-08-01 Akim Demaille <akim@epita.fr>
13610 * configure.ac: Bump to 2.52c.

13622 2001-08-01 Akim Demaille <akim@epita.fr>

13625 `die'.
13626 (&END): New.
13627 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
13628 `END', as `Autom4te::General::END' will be triggered.

13630 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

14062 provide an alternate 'main' function name, using the 'main' from
14063 the Fortran libraries.
14064 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
14065 cross-language link tests can be performed successfully.
14066 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
14067 after $LIBS, for consistency; this should be the general rule since

14074 at-stdout and at-stderr instead of removing the newline
14075 from the echo output, which is not guaranteed to work.

14145 2001-06-23 Akim Demaille <akim@epita.fr>
14147 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): Consider

14188 Automake), include the separator themselves.
14190 * acgeneral.m4 (AC_ARG_VAR): Be sure not to leave extra `;'.
14192 2001-06-19 Tim Van Holder <tim.van.holder@pandora.be>
