Subject: 1998-07-24  Ben Elliston  <bje@cygnus.com>

	* pthread.h (SIG_BLOCK): Define if not already defined.
	(SIG_UNBLOCK): Likewise.
	(SIG_SETMASK): Likewise.
	(pthread_attr_t): Add signal mask member.
	(pthread_sigmask): Add function prototype.

	* signal.c (pthread_sigmask): Implement.

	* create.c: #include <string.h> to get a prototype for memcpy().
	(pthread_create): New threads inherit their creator's signal
	mask.  Copy the signal mask to the new thread structure.
