* lib/strtod.c (strtod): Work around AIX bug of parsing p with no
exponent.

The POSIX folks admitted that codifying the behavior of GNU
getopt on a leading '+' in optstring is worthwhile, for writing
programs such as env(1) even when POSIXLY_CORRECT is not defined.
http://austingroupbugs.net/view.php?id=191
However, the ruling is an enhancement request for the next
version of POSIX, and is not binding on platforms that comply
with POSIX 2008, so it should only be enforced for getopt-gnu.
* tests/test-getopt.h (test_getopt): Strengthen tests of leading
'+' handling, when requesting extensions.
* tests/test-getopt_long.h (test_getopt_long): Strengthen test of
'W;' handling.
* m4/getopt.m4 (gl_GETOPT_CHECK_HEADERS): Detect glibc 2.11 bug.
* doc/posix-functions/getopt.texi (getopt): Document this.
* doc/glibc-functions/getopt_long.texi (getopt_long): Likewise.
* doc/glibc-functions/getopt_long_only.texi (getopt_long_only):
Likewise.
On MacOS 10.5 (Darwin 9.8.0), optind is incremented by 2 instead
of 1 in the case of a missing requirement on condensed options.
* m4/getopt.m4 (gl_GETOPT_CHECK_HEADERS): Reject MacOS botch of
optind when missing a required argument.
* doc/posix-functions/getopt.texi (getopt): Document the bug.
* doc/glibc-functions/getopt_long.texi (getopt_long): Likewise.
* doc/glibc-functions/getopt_long_only.texi (getopt_long_only):
Likewise.

Without a declaration, at least tar would core dump on 64-bit
FreeBSD because gcc only used 32 bits of the resulting pointer.
* m4/dirent_h.m4 (gl_DIRENT_H_DEFAULTS): New witness.
* m4/fdopendir.m4 (gl_FUNC_FDOPENDIR): Set it.
* modules/dirent (Makefile.am): Substitute it.
* lib/dirent.in.h (fdopendir): Supply missing FreeBSD
declaration.
* doc/posix-functions/fdopendir.texi (fdopendir): Document the
fix.

This module, like autoconf's AC_FUNC_UTIME_NULL macro, has been
unnecessary for years, and has been marked as obsolete for 10 months.
* modules/utime: Remove file.
* lib/utime.c: Remove file.
* m4/utime.m4: Remove file.
* m4/utimes-null.m4: Remove file.
* doc/posix-functions/utime.texi (utime): Remove reference to
the module. Move the sole "fixed by gnulib" item into the
"problems not fixed by Gnulib" list.
* MODULES.html.sh (func_all_modules): Remove reference to "utime".
Needed to silence compiler warnings such as:
test-gettimeofday.c:23: warning: initialization from incompatible pointer type
based on whether gettimeofday complies with POSIX or provides
the extension of struct timezone.
* m4/gettimeofday.m4 (gl_FUNC_GETTIMEOFDAY): Do better detection
of glibc extension signature, and define GETTIMEOFDAY_TIMEZONE.
* tests/test-gettimeofday.c: Use it to silence warning.
* doc/posix-functions/gettimeofday.texi (gettimeofday): Document
the issue.
