* 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.
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.
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example, since the old example is now out of date.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/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.
(&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.
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}'.
* 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.
* 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.
Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
apparently treats PATH="nonexistent" as if it contained ".".

bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,

New macro AC_GNU_SOURCE to define _GNU_SOURCE.
* NEWS: Document this.
* doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
* lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
(AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,

reverting to 2.13-compatible behavior.
Add new optional argument DIR.
(AC_FUNC_FNMATCH_GNU): New macro.

Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
that's what the code does; this fixes a bug reported by
Paul D. Smith.
If prototypes are supported, use them to check this at compile-time,
instead of trying to check it at run-time. If we must do a run-time
check, assume that setvbuf is standard when cross-compiling, as
nonstandard setvbuf occurs only on ancient and unlikely hosts.

Also, sleep 1 second after the first aclocal, to work around
problems with sub-second time stamps on the input files.

course.

(_AC_INIT_PREPARE): Use them to log them.

_AC_SUBST_FILES and _AC_SUBST_VARS.

Have M4sh perform minimal shell sanitizing.

part into...
(_AS_PREPARE): this new macro.
(AS_PREPARE): New.
(AS_INIT): Invoke AS_SHELL_SANITIZE.
* tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
Adjust Autoconf and Autotest.

* lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
Invoke _AS_PREPARE (not AS_PREPARE) in addition to

Use this M4sh to generate Autoconf's shell scripts.

* bin/autoconf.as: New, precursor of autoconf.in.
(autoconf.in): New target.
(_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
Use dnl, not the KILL diversion.
Extracted from...
(AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
(AC_CONFIG_LINKS): here.
Adjust.
Don't use the KILL diversion, as it kills spurious output, which
results in failures being hidden.
Use m4_defn where appropriate.
(AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
after the second argument.
Use m4_defn.
* lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
syntax, as it is provided by M4sugar.
* tests/torture.at (Multiple AC_CONFIG_FILES): New.
(_AC_COMPILER_EXEEXT_REJECT): New.
Also recognize *.bb and *.bbg as compilation byproducts.
(_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
(_AC_COMPILER_OBJEXT): Use them.
Fixes Debian #138666.
(Limitations of Usual Tools): Add mkdir section.
* lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
(AS_MKDIR_P): Require it. Use mkdir -p if available, falling
back on AS_DIRNAME to compute prefixes otherwise; this is
roughly what mkinstalldirs does. That way, we need not have
our own filename disassembler. The old disassembler did not
work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
* lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
Create at_test_all by a series of assignments,
not by a single assignment of a long string. The latter causes ksh
version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
presumably because of a buffer overrun.
and host is irrelevant.
(Specifying Names, Canonicalizing): Remove all references to the
backward compatibility hooks. Rather, collect them all into...
(Hosts and Cross-Compilation): this new section.
* doc/install.texi (System Type): Ditto.
* lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
that `--host' implies cross-compilation.
* lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
useless.
(_m4_foreach): Define the variant with immediate evaluation so
that it contains exactly the items, not an expression which
evaluation is the current item.
(m4_re_string, m4_re_word): Don't over quote them.
`foreach' loops immediately evaluate them.
* lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
$*. This is the n-th time I change my mind, but hopefully this is
the last...
(m4_lquote): New.
(m4_text_wrap): Use m4_foreach, which is finally correct _and_
efficient.
(m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
it was only a hack for m4_text_wrap.
(m4_car2): Remove, replaced by...
(m4_cdr): New.
(_m4_foreach): Adjust.
* lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
m4_bpatsubst for clarification.
AC_PREFIX_PROGRAM fails with dashed program names
* lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
variable when looking for the prefix program.
Now it also works for shell variables.
Describe HP-UX cc bug workaround more accurately.
* lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
not unsigned long.
* tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
cross-compilers, too. This undoes some of the most recent change
to this file.
