Symptoms:
	PHCO_27633:
	( SR:8606269542 CR:JAGae33777 )
	Enhancement: This product update is a member of a set
	needed to enable a new mutex type which can be unlocked
	by a thread other than the owner. The full list of
	product updates required for this feature are PHCO_27632
	and PHCO_27633.

	PHCO_26914:
	( SR:8606237441 CR:JAGae06481 )
	An "unexpected symbol : spu_t" compilation error occurs when
	compiling a program using c89(1) or "cc -Aa" and where
	the program includes pthread.h.

Defect Description:
	PHCO_27633:
	( SR:8606269542 CR:JAGae33777 )
	Provide a way to restart mutex operation when a process
	owning a mutex terminates abnormally.

	Resolution:
	Provide a new mutex type PTHREAD_MUTEX_NO_OWNER_NP, which
	can be unlocked by a thread other than the owner.

	PHCO_26914:
	( SR:8606237441 CR:JAGae06481 )
	The "unexpected symbol : spu_t" error is caused by pthread.h
	incorrectly including HP-UX Processor Sets headers, in which
	some symbols are defined only if _HPUX_SOURCE is defined.

	Resolution:
	The solution is to appropriately conditionalize all HP-UX
	Processor Sets references in pthread.h.
