+ (not_equal_tm) [DEBUG]: Use isdst_differ here, too.
+
+ mktime: fix some integer overflow issues and sidestep the rest
+
+ This was prompted by a bug report by Benjamin Lindner for MinGW
+ <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00472.html>.
+ His bug is due to signed integer overflow (0 - INT_MIN), and I
+ I scanned through mktime.c looking for other integer overflow
+ problems, fixing all the bugs I found.
+
+ Although the C Standard says the resulting code is still not safe
+ in the presence of integer overflow, in practice it should be good
+ enough for all real-world two's-complement implementations, except
+ for debugging environments that deliberately trap on integer
+ overflow (e.g., gcc -ftrapv).
+
+ * lib/mktime.c (WRAPV): New macro.
+ (SHR): Also check that long_int and time_t shift right in the
+ usual way, before using the fast-but-unportable method.
+ (TYPE_ONES_COMPLEMENT, TYPE_SIGNED_MAGNITUDE): Remove, no longer
+ used. The code already assumed two's complement, so there's
+ no need to test for alternatives. All uses removed.
+ (TYPE_MAXIMUM): Don't rely here on overflow behavior not defined by
+ the C standard. Problem reported by Rich Felker in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00488.html>.
+ (twos_complement_arithmetic): Also check long_int and time_t.
+ (time_t_avg, time_t_add_ok, time_t_int_add_ok): New functions.
+ (guess_time_tm, ranged_convert, __mktime_internal): Use them.
+ (__mktime_internal): Avoid integer overflow with unary subtraction
+ in two instances where -1 - X is an adequate replacement for -X,
+ since the calculations are approximate.

+ include_next: do not check for standard headers like stddef.h
+
+ I found this problem when modifying Emacs to use gnulib.
+ I noticed that it added HAVE_STDDEF_H to config.h, even though
+ gnulib always assumes <stddef.h> exists as per README and this
+ symbol is unnecessary.
+ * m4/include_next.m4 (gl_NEXT_HEADERS): New macro, which does not

+ gl_CHECK_NEXT_HEADERS used to contain. This makes 'configure' run

+ (gl_CHECK_NEXT_HEADERS): Use it.
+ * m4/float_h.m4 (gl_FLOAT_H): For float.h, use gl_NEXT_HEADERS

+
+ strftime: remove dependencies on multibyte modules
+
+ strftime depended on mbrlen, mbsinit, and wchar, but these modules
+ are needed only if ! MULTIBYTE_IS_FORMAT_SAFE, and that is true
+ only if __osf__ is defined, and I suspect OSF doesn't need these
+ other modules. If my guess is wrong, we'll need to come up with a
+ variant of strftime that doesn't need the multibyte modules.
+
+ I discovered this problem when attempting modify Emacs to use the
+ strftime module. With the previous gnulib, this caused Emacs to
+ need 31 new files, ranging from lib/config.charset to
+ m4/wint_t.m4. This was overkill and I expect would be offputting
+ to the Emacs maintainers. After this change, only 6 new files are
+ needed, namely strftime.[ch], srtftime.m4, stdbool.in.h,
+ stdbool.m4, and tm_gmtoff.m4.
+
+ * lib/strftime.c (MULTIBYTE_IS_FORMAT_SAFE): Define to 1 always.
+ Suggested by Bruno Haible in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00238.html>.
+ * m4/strftime.m4 (gl_FUNC_STRFTIME): Do not require AC_TYPE_MBSTATE_T,
+ and do not check for wchar.h.
+ * modules/strftime (Files): Remove m4/mbstate_t.m4.
+ (Depends-on): Remove mbrlen, mbsinit, wchar.

+
+ openat, save-cwd: avoid xmalloc
+
+ This removes a direct (but undocumented) dependency of openat on
+ xalloc, along with an indirect dependency via save-cwd. It also
+ removes a dependency of save-cwd on xgetcwd, and thereby
+ indirectly on xalloc. This change causes the openat substitute
+ to fall back on save_cwd when memory is tight, and for save_cwd to
+ fail instead of dying when memory is tight, but that's good enough.
+
+ * lib/openat-proc.c: Include stdlib.h (for malloc), not
+ xalloc.h (for xmalloc).
+ (openat_proc_name): Use malloc, not xmalloc.
+ * lib/save-cwd.c (save_cwd): Use getcwd, not xgetcwd.
+ * modules/save-cwd (Files): Depend on getcwd, not xgetcwd.
+
+ openat: Increase OPENAT_BUFFER_SIZE from 512 to at least 1024
+ This avoids heap allocation for file names whose lengths are in
+ the range 512..1023, with the upper bound increasing to at most
+ 4031 depending on the platform's PATH_MAX. (We do not want
+ pathmax.h here as it might supply a non-constant PATH_MAX.)
+ * lib/openat-priv.h (SAFER_ALLOCA_MAX, SAFER_ALLOCA): New macros.
+ Perhaps they should be moved to malloca.h?
