-        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>.

-        (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,

+        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.

+
+        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.
