* conform/conformtest.pl (checknamespace): Sort the output list.
	* sysdeps/generic/bits/poll.h (POLLWRBAND): New alias for POLLOUT.
	(POLLRDNORM, POLLRDBAND, POLLWRNORM, POLLWRBAND): Make these
	definitions conditional on [__USE_XOPEN].

	* sysdeps/mach/hurd/bits/fcntl.h (O_ASYNC, O_FSYNC, O_SYNC): Define
	these unconditionally, not only use [__USE_BSD], so as to match
	the sysdeps/unix/sysv/linux files.
