--- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> --- On second thoughts, we probably don't need to worry about SYS_clock_gettime_time64. We only use SYS_clock_gettime syscalls on old glibc systems where clock_gettime is in librt not libc, and those systems aren't going to get updated with the time64 version.
