 * Note: The values shown below as a comment for the __POSIX_VISIBLE values are
 * the ones FreeBSD traditionally used based on our reading of the POSIX
 * standards. However, glibc uses 199309 for all of them, even those many were
 * not defined there. To remain bug compatible with glibc means more software
 * that relied on the glibc behavior will compile easily on FreeBSD.
 *
 * Also, CLOCK_UPTIME_FAST is improperly visible temporarily for the lang/pocl
 * port until it can be updated properly. It incorrectly assumes that this was a
 * standard value. It will be moved back to the __BSD_VISIBLE section once the
 * issue is corrected.
