Clean up _AC_COMPILER_EXEEXT* macros.
* lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
ac_file to the name of the default output file and call
_AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
initial `rm' of the candidate files...
(_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
the same list in subsequent `rm' calls, and for the temporary
redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
(_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
(_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
no longer needed) by libtool. Make it a cache check.
(_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
copied here by mistake.
(AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
_AC_COMPILER_EXEEXT.
* lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
_AC_COMPILER_OBJEXT directly.
* lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
* lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
ENOLCK. Only mention `make -j' when applicable. Only raise
fatal errors when `make -j' is involved. Improve error message.

runs afoul of the Korn shell version M-12/28/93d bug described in

Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
AC_PROG_SED. Move descriptions of limitations
to the Limitations of Usual Tools section.
(Limitations of Usual Tools) <sed>: Mention script length
limitations with Solaris /usr/ucb/sed.
<grep>: Fix wording for empty alternative. Mention that -c and
-l should not be combined, and that -E and -F should not be
combined.
AC_DEFINE is now passed to m4_pattern_allow.
* NEWS: Mention that; likewise for AC_SUBST.
* lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
the parameter to m4_pattern_allow.
* tests/tools.at: Add a check for that.

2006-01-13 Jim Meyering <jim@meyering.net>
Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
$ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
not double-quote uses of that variable, to accommodate the rare
case in which getmntent is available in none of the libraries
checked. This happens at least on FreeBSD 5.0.

some other programs unwisely rely on these undocumented vars.
But put in warning comments about them.
Problem reported by Ralf Wildenhues in

Warn about obsolete install-sh files. Remove stray sentence

(MKDIR_P): Mark with AN_MAKEVAR.
(AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
that we don't require $INSTALL to be thread-safe. Move comments
out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
of AC_PROG_INSTALL. Output a message saying that we're checking
mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
MKDIR_P instead of AC_SUBST.
* lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
Special magic for MKDIR_P, too.
* lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
a dnl.
* tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.

(autom4te): Document in `missing --help'.
* config/install-sh: Don't use 'path' to talk about file names,
as per GNU coding standards. Close a race condition reported by Ralf
Wildenhues and Stepan Kasal. There is still a race condition
on hosts that predate POSIX 1003.1-1992, but we can't help this.
Don't mishandle weird characters like space on pre-POSIX hosts.
Invoke mkdir at most once per dir arg on pre-POSIX hosts.
* doc/autoconf.texi (Programming in M4sh): Cross-reference to
AC_PROG_MKDIR_P from AS_MKDIR_P.

earlier editions are not (including Automake 1.8.3).
Do not suggest mkinstalldirs for thread-safety.
* lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the

We have to keep AS_DIRNAME since it was part of a stable Autoconf,
but AS_BASENAME doesn't have to be supported.

AS_VAR_SET_DIRNAME and AS_VAR_SET_BASENAME.
* doc/autoconf.texi (Programming in M4sh): Document this. All uses
changed. The newer interfaces are more reliable, as they allow
implementations that handle trailing newline correctly. For now,
we're in a freeze, so I did not include the more-reliable
implementations, but I wanted to correct the interface before 2.60
goes out.
