	* posix/unistd.h [__USE_BSD] (ttyslot): Declare it.

	* posix/unistd.h [__USE_BSD] (L_SET, L_INCR, L_XTND): Define
 	unless L_SET already defined.
	* misc/sys/file.h (L_SET, L_INCR, L_XTND): Don't define if L_SET
 	already defined.

	Incorporated -lutil library from 4.4-Lite.
	* misc/Makefile (extra-libs, libutil-routines): New variables.
	* misc/login.c, misc/login_tty.c, misc/logout.c, misc/logwtmp.c,
	sysdeps/generic/pty.c: New files for -lutil incorporated from 4.4-Lite.

	Support simple, light-weight unwind-protect mechanism for longjmp.
	* setjmp/longjmp.c: Call _longjmp_unwind first thing.
	* sysdeps/mach/hurd/jmp-unwind.c: New file.
	* sysdeps/stub/jmp-unwind.c: New file.
	* sysdeps/i386/jmp_buf.h (_JMPBUF_UNWINDS): New macro.
	* sysdeps/mips/jmp_buf.h (_JMPBUF_UNWINDS): New macro.
	* setjmp/Makefile (routines): Add jmp-unwind.
	* hurd/hurd/userlink.h (struct hurd_userlink): Move `next' and
 	`prevp' members into new substructure `resource'; add another such
 	substructure `thread' and members `cleanup' (function ptr) and
 	`cleanup_data' (generic ptr).
	(_hurd_userlink_link, _hurd_userlink_unlink): Insert/remove LINK
	into the `_hurd_self_sigstate ()->active_resources' list via the
	`thread' substructure.
	* hurd/hurd/port.h (_hurd_port_cleanup): Declare it.
	(_hurd_port_locked_get): Set LINK->cleanup to _hurd_port_cleanup and
	LINK->cleanup_data' to the port extracted.
	* hurd/hurd/signal.h (struct hurd_sigstate): New member
	`active_resources'.
	* hurd/port-cleanup.c: New file.
	* hurd/Makefile (routines): Add port-cleanup.

	* malloc/malloc.c: Include errno.h.
