+
+ * Makefile.in, gnulib.mk: Regenerate.
+ This merges the following fix from gnulib:
+
+ 2011-02-08 Bruno Haible <[email protected]>
+
+ Split large sed scripts, for HP-UX sed.
+
+2011-02-06 Paul Eggert <[email protected]>
+
+ gnulib: allow multiple gnulib generated replacements to coexist
+ This defines a few preprocessor symbols that should not affect Emacs.
+ * getopt.in.h, time.in.h, unistd.in.h: Regenerate
+ via "make sync-from-gnulib".
+
+ gnulib: undo previous change
+ The upstream _HEADERS change was backed out of gnulib (see the
+ same thread). Stay in sync with gnulib.
+
+ gnulib: adjust to upstream _HEADERS change
+ * Makefile.am (EXTRA_HEADERS, nodist_pkginclude_HEADERS):
+ New empty macros, to accommodate recent changes to gnulib. See
+ <http://lists.gnu.org/archive/html/bug-gnu2011-02/msg00068.html>.
+ * Makefile.in, ftoastr.h, getopt.in.h:
+ * gnulib.mk, ignore-value.h, stdbool.in.h, stddef.in.h:
+ * time.in.h, unistd.in.h:
+ Regenerate.
+
+2011-02-03 Paul Eggert <[email protected]>
+
+ allow C code to suppress warnings about ignored return values
+ * Makefile.in, gnulib.mk: Regenerate.
+ * ignore-value.h: New file.
+
+2011-01-31 Eli Zaretskii <[email protected]>
+
+ * makefile.w32-in (GNULIBOBJS): Add $(BLD)/strftime.$(O) and
+ $(BLD)/time_r.$(O).
+ ($(BLD)/dtoastr.$(O)): Depend on $(EMACS_ROOT)/src/s/ms-w32.h and
+ $(EMACS_ROOT)/src/m/intel386.h.
+ ($(BLD)/strftime.$(O)):
+ ($(BLD)/time_r.$(O)): Define prerequisites.
+

+
+ strftime: import from gnulib
+ * Makefile.in, gnulib.mk:
+ Regenerate.
+ * strftime.c, strftime.h, stdbool.in.h: New files,
+ imported from gnulib.
+ This incorporates many changes from gnulib, including simpler
+ handling of multibyte formats, porting to mingw32 and other
+ platforms, and support for higher-resolution time stamps.
+ Emacs does not yet use the higher-resolution interface.
+

+
+ gnulib: import mktime and move-if-change fixes from gnulib
+
+ * configure: Regenerate from the following.
+
+ 2011-01-30 Paul Eggert <[email protected]>
+
+ mktime: clarify long_int width checking
+ * mktime.c (long_int_is_wide_enough): Move this assertion to
+ the top level, to make it clearer that the assumption about
+ long_int width is being checked. See
+ <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00554.html>.
+
+ 2011-01-29 Paul Eggert <[email protected]>
+
+ TYPE_MAXIMUM: avoid theoretically undefined behavior
+ * intprops.h (TYPE_MINIMUM, TYPE_MAXIMUM): Do not shift a
+ negative number, which the C Standard says has undefined behavior.
+ In practice this is not a problem, but might as well do it by the book.
+ Reported by Rich Felker and Eric Blake; see
+ <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00493.html>.
+ * mktime.c (TYPE_MAXIMUM): Redo slightly to match the others.
+
+ mktime: #undef mktime before #defining it
+ * mktime.c (mktime) [DEBUG]: #undef mktime before #defining it.
+
+ mktime: systematically normalize tm_isdst comparisons
+ * mktime.c (isdst_differ): New function.
+ (__mktime_internal): Use it systematically for all isdst comparisons.
+ This completes the fix for libc BZ #6723, and removes the need for
+ normalizing tm_isdst. See
+ <http://sourceware.org/bugzilla/show_bug.cgi?id=6723>
+ (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).
+
+ * 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.
+
+ 2011-01-28 Paul Eggert <[email protected]>
+
+ mktime: avoid problems on NetBSD 5 / i386
+ * mktime.c (long_int): New type. This works around a problem
+ on NetBSD 5 / i386, where 'long int' and 'int' are both 32 bits
+ but time_t is 64 bits, and where I expect the existing code is
+ wrong in some cases.
+ (leapyear, ydhms_diff, guess_time_tm, __mktime_internal): Use it.
+ (ydhms_diff): Bring back the compile-time check for wide-enough
+ year and yday.
+
+ mktime: fix misspelling in comment
+ * mktime.c (__mktime_internal): Fix misspelling in comment.
+ This merges all recent glibc changes of importance.
