+
+ Make mktime etc. compatible with __time64_t
+ Keep these functions compatible with Gnulib while adding
+ __time64_t support. The basic idea is to move private API
+ declarations from include/time.h to time/mktime-internal.h, since
+ the former file cannot easily be shared with Gnulib whereas the
+ latter can.
+ Also, do some other minor cleanup while in the neighborhood.
+ * include/time.h: Include stdbool.h, time/mktime-internal.h.
+ (__mktime_internal): Move this prototype to time/mktime-internal.h,
+ since Gnulib needs it.
+ (__localtime64_r, __gmtime64_r) [__TIMESIZE == 64]:
+ Move these macros to time/mktime-internal.h, since Gnulib needs them.
+ (__mktime64, __timegm64) [__TIMESIZE != 64]: New prototypes.
+ (in_time_t_range): New static function.
+ * posix/bits/types.h (__time64_t): Move to time/mktime-internal.h,
+ so that glibc users are not tempted to use __time64_t.
+ * time/mktime-internal.h: Rewrite so that it does both glibc
+ and Gnulib work. Include time.h if not _LIBC.
+ (mktime_offset_t) [!_LIBC]: Define for gnulib.
+ (__time64_t): New type or macro, moved here from
+ posix/bits/types.h.
+ (__gmtime64_r, __localtime64_r, __mktime64, __timegm64)

+ from include/time.h.
+ (__gmtime_r, __localtime_r, __mktime_internal) [!_LIBC]:

+ (__mktime_internal): New prototype, moved here from include/time.h.
+ * time/mktime.c (mktime_min, mktime_max, convert_time)
+ (ranged_convert, __mktime_internal, __mktime64):
+ * time/timegm.c (__timegm64):
+ Use __time64_t, not time_t.
+ * time/mktime.c: Stop worrying about whether time_t is floating-point.
+ (__mktime64) [! (_LIBC && __TIMESIZE != 64)]:
