* 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.
expansion in the here-documents used by config.status, as that
runs afoul of the Korn shell version M-12/28/93d bug described in
the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
<http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
ac_dB slightly, to save bytes in the script.
Max out at 50 lines, rather than 96; this is more likely
(though not guaranteed) to avoid obscure 'sed' failures.
we always prefer the GNU version of the program, and that we
search according to PATH; both rules can have exceptions.
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.
the HP-UX sed limitation of 99 commands, labels do not count.
* lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
in the comment.
(_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
Import the following fix from coreutils:
2006-01-13 Jim Meyering <jim@meyering.net>
Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
$ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
not double-quote uses of that variable, to accommodate the rare
case in which getmntent is available in none of the libraries
checked. This happens at least on FreeBSD 5.0.
ac_config_guess, ac_config_sub, and ac_configure, since evidently
some other programs unwisely rely on these undocumented vars.
But put in warning comments about them.
Problem reported by Ralf Wildenhues in
<http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
* NEWS: Document that these variables are intended to go away.
lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
Automake as follows:
* lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
`$configure_in' instead of `configure.in', to preserve
directory component.
sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
Warn about obsolete install-sh files. Remove stray sentence
fragment and fix cross reference.
* lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
install -d; this undoes the 2006-05-10 change.
(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.
2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* config/install-sh: Initialize IFS, so field splitting isn't
turned off later.
* config/mkinstalldirs: Likewise.
* config/missing: Remove superfluous quotes. Replace all uses of
`[' by `test', for consistency, and for..
* config/missing (sed_minuso, sed_output): New variables.
(autom4te, help2man, makeinfo): Use them. Unifies detection of
`-o FILE', `--output FILE', `--output=FILE', stricter regex.
Fixes `missing' to detect `--output' for help2man. Fixes
PR automake/483. Report by Dennis J. Linse.
(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.
(Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
from mkdir. Mention that Autoconf 2.60 install-sh is safe but
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
presence of special characters and race conditions.
* tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
in Autoconf's name space.
* lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
from Automake with minor changes.
* doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
munge (multiple) white space and other oddities.
* tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
single quotes in variable assignment.
(AC_ARG_VAR, configure invocation): Adjust tests to expose this
and similar failures by adding multiple spaces, tabs, and other
special characters.
Report and different test suggested by Francesco Romani
<fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
single quotes, we only need to search for single quotes; this
both simplifies the search pattern, and makes us less
susceptible to `echo' variations for arguments not containing
single quotes.
(_AC_ARG_VAR_VALIDATE): Likewise.
traditional shells like the Solaris one that do not use the
first IFS character for assembling `$*'.
Prompted by a related report from autoconf_bug@nro.ca.
in URLs to improve DVI formatted output (requires texinfo 4.6).
(System Services, Systemology, Shellology): Likewise.
(Limitations of Usual Tools): Rewrite Mac OS X example for nicer
output.
