[v3,22/24] libsupport: Add 64-bit time_t support for time functions
Checks
Commit Message
The patch adds redirections for xclock_gettime, xclock_settime,
timespec_add, timespec_sub, test_timespec_before_impl,
test_timespec_equal_or_after_impl, support_timespec_ns,
support_timespec_normalize, and support_timespec_check_in_range when
_TIME_BITS=64 is defined.

No regressions on x86_64 and i686 and reviewed resulting ABI for correctness.

OK. All occurrences of "64 bit" in v2 removed and fixed in v3.
