NEWS:
** Executables
- autoreconf no longer changes the version of the gettext/po/intl
support files. It now adds the files the correspond to the
AM_GNU_GETTEXT_VERSION declared in configure.ac.
Warning: It now relies on the 'autopoint' program, which is part
of GNU gettext 0.11.4 and newer.
Please note that you need to have a GNU gettext version that
corresponds at least to the AM_GNU_GETTEXT_VERSION declared
in configure.ac. You can upgrade to newer GNU gettext versions,
though, without needing to change configure.ac.
- The -I DIR or --include=DIR option now appends DIR to the include path
instead of prepending; this is for consistency with other GNU tools.
The new -B DIR or --prepend-include=DIR option has the old behavior.
** Macros
- AC_OUTPUT
Now handles all the gory details about LIBOBJS and LTLIBOBJS.
Please, remove lines such as
# This is necessary so that .o files in LIBOBJS are also
# built via the ANSI2KNR-filtering rules.
LIBOBJS=`echo $LIBOBJS|sed 's/\.o /\$U.o /g;s/\.o$/\$U.o/'`
and read the `AC_LIBOBJ vs LIBOBJS' section. Do not define U in
your Makefiles either.
- AC_CONFIG_LINKS now makes copies if it can't make links.
- AC_FUNC_FNMATCH now tests only for POSIX compatibility, reverting to
Autoconf 2.13 behavior. The new macro AC_FUNC_FNMATCH_GNU also
tests for GNU extensions to fnmatch, and replaces fnmatch if needed.
- AC_FUNC_SETVBUF_REVERSED no longer fails when cross-compiling.
- AC_PROG_CC_STDC is integrated into AC_PROG_CC.
- AC_PROG_F77 default search no longer includes cf77 and cfg77.
- New macros
AC_C_BACKSLASH_A, AC_CONFIG_LIBOBJ_DIR, AC_GNU_SOURCE,
AC_PROG_EGREP, AC_PROG_FGREP, AC_REPLACE_FNMATCH,
AC_FUNC_FNMATCH_GNU, AC_FUNC_REALLOC, AC_TYPE_MBSTATE_T.
- AC_FUNC_GETLOADAVG
looks for getloadavg.c in the CONFIG_LIBOBJ_DIR.
- AC_FUNC_MALLOC
Now defines HAVE_MALLOC to 0 if `malloc' does not work, and asks
for an AC_LIBOBJ replacement.
** Bug fixes
- Spurious complaints from `m4_bmatch' about invalid regular
expressions are suppressed.
- Empty top_builddirs are properly handled.
- AC_CHECK_MEMBER works correctly when the member is an aggregate.
- AC_PATH_PROG
Now colon in the optional path arguments are properly handled.
** Improved portability
- Both Autoconf the package, and the scripts it produces, should run
more reliably with Zsh. Bear in mind it is the default Bourne shell
on Darwin.
- Autoconf and the scripts it produces no longer assume the existence of
the obsolescent commands egrep and fgrep.
** Documentation
- Limitations of Make
More of them.
- GNATS
The GNATS base has moved to
http://bugs.gnu.org/cgi-bin/gnatsweb.pl?database=autoconf
** Misc.
- config.log
Now contains the list of ouput variables and files (AC_SUBST,
AC_SUBST_FILES).

ChangeLog 3 Sep 2002 06:15:44 -0000 1.1991
**********************************************************************
2002-09-03 Akim Demaille <[EMAIL PROTECTED]>
Version 2.53c.
2002-09-02 Akim Demaille <[EMAIL PROTECTED]>
* bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
SITE_MACRO_DIR.
* configure.ac: Disable SITE_MACRO_DIR.
2002-09-02 Jim Meyering <[EMAIL PROTECTED]>
* doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
Also, tweak grammar: s/make sure to/be sure to/.
2002-09-02 Paul Eggert <[EMAIL PROTECTED]>
* doc/autoconf.texi (Limitations of Builtins): Explain why logical
directory names are generally preferable to physical names.
2002-09-02 Akim Demaille <[EMAIL PROTECTED]>
* lib/Autom4te/General.pm (&update_file): s/die/error/.
Reported by Raja R. Harinath.
* bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
* bin/autoupdate.in: Use error instead of die.
2002-09-01 Paul Eggert <[EMAIL PROTECTED]>
* tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
ordinary shell concatenation rather than echo+tr+sed command that
runs afoul of a long-line-related sed bug in Solaris 8.
* bin/autoheader.in (parse_args): --warning -> --warnings.
* bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
stdout, as traditional "ls" does.
* lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
_AC_COMPILER_EXEEXT_O): Likewise.
* doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
* bin/autoconf.as: Add --prepend-include option. This patch was
applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
but bin/autoconf.in is generated automatically from bin/autoconf.as.
* bin/autoconf.in, configure: Regenerate.
* doc/autoconf.texi (Special Shell Variables): Mention
ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
MAILPATH and set PS1, PS2, PS4 to default values, to work
around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
For LC_ALL etc, first try to set to "C" as POSIX requires and as
the Autoconf documentation specifies; fall back to "unset" only if
this fails. Use a shell for-loop for this rather than an m4 loop,
to shorten the output script.
2002-08-30 Paul Eggert <[EMAIL PROTECTED]>
* doc/autoconf.texi (Special Shell Variables): Mention POSIX
1003.1-2001's requirements for CDPATH. Give a simpler workaround
for the CDPATH problem. Document PWD.
(Limitations of Builtins): Document the problem that "cd $foo" and
"ls $foo" may refer to different directories in shells conforming
to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
example, since the old example is now out of date.
* lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
FOO" and "ls FOO" talk about different directories; this catches
problems when POSIX 1003.1-2001 "cd" fails due to symlink
spaghetti.
* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
of rolling our own unset.
(_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
in practice we needn't worry about CDPATH if unset doesn't work.
* Makefile.in, aclocal.m4, bin/Makefile.in,
config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
tests/Makefile.in: Regenerate with Automake 1.6.3.
* config/config.guess, config/config.sub, config/mkinstalldirs:
Update.
* configure: Regenerate with self.
2002-08-30 Kevin Ryde <[EMAIL PROTECTED]>
* doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
default output.
2002-08-29 Rainer Orth <[EMAIL PROTECTED]>
* bin/autom4te.in (Request::load): Correctly test for "do" read
failure.
2002-08-29 Akim Demaille <[EMAIL PROTECTED]>
* lib/Autom4te/General.pm (&xqx): New.
(&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
hand, which is not portable.
(&error): New.
* bin/autom4te.in: Use them.
Use &error instead of die.
* tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
Adjust.
2002-08-17 Paul Eggert <[EMAIL PROTECTED]>
* lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
default list of compilers to try, since it was long ago superseded
by the ksh fc builtin. Suggested by Steven G. Johnson.
2002-07-31 Alexandre Duret-Lutz <[EMAIL PROTECTED]>
* doc/autoconf.texi (Invoking autom4te): End the option table,
fixing a bug introduced by the previous patch.
(Limitations of Make): Add a 'target lookup' subentry in the
'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
2002-07-29 Mark D. Roth <[EMAIL PROTECTED]>
* bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
options and use $AUTOM4TE_PATH.
* doc/autoconf.texi: Remove documentation of autom4te
--include-envvar and --site-macro-subdir options and document
use of $AUTOM4TE_PATH.
* lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
arguments from each language section.
2002-07-29 Paul Eggert <[EMAIL PROTECTED]>
* doc/install.texi: Include copyright symbol in copyright notice.
* Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
Replace with:
(AM_MAKEINFOFLAGS): New macro.
* doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
* Makefile.am (INSTALL): Use the new macros.
Use -o rather than --output, since "missing" does not grok --output.
2002-07-25 Alexandre Duret-Lutz <[EMAIL PROTECTED]>
* doc/autoconf.texi (Limitations of Make): Escaped newlines in
comments do not always work. Never trust the exit status of
`make -k'.
2002-07-24 Kevin Ryde <[EMAIL PROTECTED]>
* autoconf.texi (Limitations of Make, Making testsuite Scripts):
Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
2002-07-23 Paul Eggert <[EMAIL PROTECTED]>
* lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
apparently treats PATH="nonexistent" as if it contained ".".
Bug reported by Stefan `Sec' Zehl.
2002-07-22 Alexandre Duret-Lutz <[EMAIL PROTECTED]>
* doc/autoconf.texi (Limitations of Make): Mention the special
handling of the obj/ directory by BSD make.
2002-07-20 Kevin Ryde <[EMAIL PROTECTED]>
* doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
backslashes.
2002-07-19 Akim Demaille <[EMAIL PROTECTED]>
* doc/autoconf.texi (Function Portability): `exit'.
(Programming in M4sh): Ethymology of M4sh.
2002-07-19 Akim Demaille <[EMAIL PROTECTED]>
* doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
