Subject: i1998-07-22  Ben Elliston  <bje@cygnus.com>

	* attr.c (pthread_setstacksize): Update test of attr argument.
	(pthread_getstacksize): Likewise.
	(pthread_setstackaddr): Likewise.
	(pthread_getstackaddr): Likewise.
	(pthread_attr_init): No need to allocate any storage.
	(pthread_attr_destroy): No need to free any storage.

	* mutex.c (is_attr): Not likely to be needed; remove.
	(remove_attr): Likewise.
	(insert_attr): Likewise.

	* pthread.h (pthread_attr_t): Moved here from implement.h.

	* implement.h (_pthread_mutexattr_t): Moved to a public definition
	in pthread.h.  There was little gain in hiding these details.
	(_pthread_condattr_t): Likewise.
