+ TYPE_MAXIMUM: avoid theoretically undefined behavior

+ * lib/mktime.c (isdst_differ): New function.

+ 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).
+
+ * 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.
+
+2011-01-29 Eric Blake <eblake@redhat.com>
+
+ mktime: avoid infinite loop
+ * m4/mktime.m4 (AC_FUNC_MKTIME): Avoid overflow on possibly-signed
+ type; behavior is still undefined but portable to all known targets.
+ Reported by Rich Felker.

+
+ mktime: avoid problems on NetBSD 5 / i386
+ * lib/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.
