Update.
2003-01-13  Martin Schwidefsky  <schwidefsky@de.ibm.com>

	* sysdeps/unix/sysv/linux/s390/s390-32/pt-initfini.c: Avoid
	unterminated string literals.
	* sysdeps/unix/sysv/linux/s390/s390-64/pt-initfini.c: Likewise.

2003-01-13  Martin Schwidefsky  <schwidefsky@de.ibm.com>

	* sysdeps/unix/sysv/linux/s390/s390-32/sysdep-cancel.h
	(PSEUDO): Code reordering.  Move CENABLE and CDISABLE literals from
	PSEUDO_END to PSEUDO.
	(PSEUDO_END): Remove.
	(SINGLE_THREAD_P): Save an instruction.
	* sysdeps/unix/sysv/linux/s390/s390-32/vfork.S (__vfork): Add missing
	parameter to SINGLE_THREAD_P call.
	* sysdeps/unix/sysv/linux/s390/s390-64/sysdep-cancel.h (PSEUDO):
	Code reordering.
