48 * the ones FreeBSD traditionally used based on our reading of the POSIX

51 * that relied on the glibc behavior will compile easily on FreeBSD.
53 * Also, CLOCK_UPTIME_FAST is improperly visible temporarily for the lang/pocl
54 * port until it can be updated properly. It incorrectly assumes that this was a
55 * standard value. It will be moved back to the __BSD_VISIBLE section once the
