* login/utmp_file.c (pututline_file): Correctly decide whether
	LAST_ENTRY matches DATA.
	Don't depend on ut_id ever being set.
	(proc_utmp_eq): New function.
	(internal_getut_r): Renamed from internal_getutid_r.
	Use proc_utmp_eq.

	* login/logout.c (logout): Change type of entry to be DEAD_PROCESS.

	* sysdeps/mach/hurd/fcntlbits.h (O_NORW): New macro.
