Update.

	* conform/data/sys/socket.h-data: Fix typos.  Correct getsockopt,
	recvfrom, send, and socketpair prototypes.  Add allow lines.
	* socket/sys/socket.h: Include <sys/uio.h>.
	Don't use fancy __SOCKADDR_ARG definition unless __USE_GNU.
	Fix type of second parameter of listen.
	Don't declare isfdtype unless __USE_MISC.
	* sysdeps/generic/listen.c: Fix type of second parameter of listen.
	* sysdeps/mach/hurd/listen.c: Likewise.
	* sysdeps/generic/bits/socket.h (struct sockaddr_storage): Define
	ss_family and __ss_family.
	* sysdeps/unix/sysv/aix/bits/socket.h: Likewise.
	* sysdeps/unix/sysv/linux/bits/socket.h: Likewise.
	(struct msghdr): Change type of msg_iovlen to int and type of
	msg_controllen to socklen_t.
	* sysdeps/unix/sysv/linux/alpha/bits/socket.h: New file.
	* sysdeps/unix/sysv/linux/ia64/bits/socket.h: New file.
	* sysdeps/unix/sysv/linux/sparc/sparc64/bits/socket.h: New file.
