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

is enabled by default with gnu and gnits strictness.
Report from Bruno Haible.

Import these changes from Texinfo:
2006-10-04 Karl Berry <karl@gnu.org>
* build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

(\codequoteleft): new def, to look for @set codequotebacktick.
(\lquoteexpand, \quoteexpand): new defs.
(\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
(\code): must use new \...Char values, since now ` is active.

2006-08-12 Karl Berry <karl@gnu.org>

* lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
(_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
2006-10-11 Stepan Kasal <kasal@ucw.cz>
* lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
initialization which is not inherited through the environment
(_AS_BOURNE_COMPATIBLE): ... to this new macro.
(_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
shel scripts no longer export BIN_SH, due to configuration
hassles with this.
* lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH
or DUALCASE.
(_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
Use AS_EXECUTABLE_P rather than test -f.
(AS_SHELL_SANITIZE): Set DUALCASE.
(AS_EXECUTABLE_P): Just invoke as_executable_p.
(_AS_TEST_PREPARE): Default to test -f, rather than to nothing.
argument to `--prefix' for sub-configure scripts.
Pass `--silent' to sub-configure scripts.
* tests/torture.at (Configuring subdirectories): Add tests
for both changes.
* doc/autoconf.texi (Setting Output Variables): Fix example to
not show `--silent' being passed to a `configure' re-run.
* lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
for the existence of the directory at configure-time. That's
too late, anyway, and possibly the directory isn't part of the
distribution. Problem reported by Stefan Seefeld.
f90/f95 because the latter drivers of AIX Fortran 9.1 do not
accept files with extension `.f'. For consistency, also prefer
xlf over f77.
* doc/autoconf.texi (Fortran Compiler): Remove mention of bug
from last patch.
old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
except the first two arguments are reversed.
* doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
(Generic Compiler Characteristics): AC_COMPUTE_INT no longer
caches nor outputs a diagnostic. Suggested by Bruno Haible.
* lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
equivalent to the old AC_COMPUTE_INT.
(AC_COMPUTE_INT): No longer caches or reports. New signature.
All uses changed to AC_CACHE_CHECK_INT.
* tests/base.at (AC_CACHE_CHECK_INT): New test.
* tests/mktests.sh (ac_exclude_lsit): Add AC_CACHE_CHECK_INT.
and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
programs should use their Gnulib counterparts.
* doc/autoconf.texi (Particular Functions): Likewise.
(Macro Names, testsuite Invocation): Replace uses of these
obsolete macros with uses of non-obsolete macros.
* doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
for the default, which the user can override.
* lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
deal with LEXLIB.
(_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
didn't work if some values were cached but not others. Test for
broken lex libraries like native ia64-hp-hpux11.22; see
<http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
work around the problem by preferring an empty LEXLIB to -lfl or
-ll. Let the user set LEXLIB='' to indicate no library needed.
rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
-Wundef -Werror". Problem reported by David Fang in

S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
this.
"HP" and "HP-UX". Remove mention of OSF; the old version wasn't
quite right (it talked about "OSF/Tru64", even though the
operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
and it even mentioned "OSF 4"!) and at this point there's little
reason to talk about OSF any more, since it died in 1994.
(Specific Compiler Characteristics): Simplify example of
negative-size array.
(File Descriptors): Reorder to make the text flow better.
Remove joke about "appreciate the various levels"; I didn't get it.
Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
<http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
(File Descriptors, Limitations of Usual Tools):
Tone down the advice against renaming or removing open files.
(Limitations of Usual Tools): Add a new section, on 'rm'.

to document the whole `datarootdir' business a bit better.
* NEWS: Update.
* tests/torture.at (datarootdir workaround): Extend test.
Prompted by report by Alexandre Julliard.
Problem reported by Eric Blake.
* doc/autoconf.texi: Likewise.
Use @acronym around BSD, GCC, and GNU when appropriate.
(Why GNU M4): Renamed from "Why GNU m4".
(Redefined M4 Macros): Mention that Posix
m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
(Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
to int.
