commit f6abd970284a06380cd9d905f43da104bd49fc95 (HEAD -> master, jolly/master)
Author: Samuel Thibault <samuel.thibault@ens-lyon.org>

hurd: Add WSTOPPED/WCONTINUED/WEXITED/WNOWAIT support [BZ #23091]

The new __proc_waitid RPC now expects WEXITED to be passed, allowing to
    properly implement waitid, and thus define the missing W* macros
    (according to FreeBSD values).
