This was used before, we still have some leftovers from it:
nscd/nscd.c:306:# ifndef __ASSUME_IN_NONBLOCK
resolv/res_send.c:1035:#ifndef __ASSUME_SENDMMSG
resolv/res_send.c:1081:#ifndef __ASSUME_SENDMMSG
resolv/res_send.c:1100:#ifndef __ASSUME_SENDMMSG
You have also cleanup some other assumes from Hurd: dup3 (b48061e1a534a242),
O_CLOEXEC (cef9b65376a04430), and accept4 (e92030239abb4038).
