	(struct lastlog) [__WORDSIZE == 64 && __WORDSIZE_COMPAT32]:
	Use int32_t for ll_time.
	(struct utmp) [__WORDSIZE == 64 && __WORDSIZE_COMPAT32]:
	Use int32_t instead of long int for ut_session.
	Use an anonymous struct with 32-bit fields for ut_tv.
	* sysdeps/gnu/bits/utmpx.h: Include <bits/wordsize.h>.
	(struct utmpx) [__WORDSIZE == 64 && __WORDSIZE_COMPAT32]: Do the same
	here as in utmp.h for `struct utmp'.

	* sysdeps/unix/sysv/linux/bits/socket.h (struct msghdr): Use size_t
	instead of int for msg_iovlen, instead of socklen_t for msg_controllen.
	Other than the previously incorrect sign of msg_iovlen, this is a
	no-op on 32-bit platforms.  On 64-bit platforms it makes this header
	match their layouts as well, so the following are now identical to it.
