The symbols gai_cancel, gai_error, gai_suspend, getaddrinfo_a, __gai_suspend_time64 were moved using scripts/move-symbol-to-libc.py. For Hurd (which remains !PTHREAD_IN_LIBC), a few #define redirects had to be added because several pthread functions are not available under __. (Linux uses __ prefixes for most hidden aliases, and has to in some cases to avoid linknamespace issues.)
