	* include/pthread/pthread.h (pthread_exit): Add noreturn
	attribute.

	* sysdeps/generic/bits/condition.h (__PTHREAD_COND_INITIALIZER):
	Don't create a compound literal.
	* sysdeps/generic/bits/mutex.h (__PTHREAD_MUTEX_INITIALIZER):
	Don't create a compound literal.
	(pthread_mutex_init): Don't assign to *__MUTEX directly.
	Initialize an intermediate local variable and then copy the
	result.
	* sysdeps/generic/bits/rwlock.h (__PTHREAD_RWLOCK_INITIALIZER):
	Don't create a compound literal.
	(pthread_rwlock_init): Don't assign to *__RWLOCK directly.
	Initialize an intermediate local variable and then copy the
	result.
	* sysdeps/i386/bits/spin-lock.h (__SPIN_LOCK_INITIALIZER):
	Don't create a compound literal.

	* pthread/pt-alloc.c (initialize_pthread): Cast
	PTHREAD_MUTEX_INITIALIZER and PTHREAD_COND_INITIALIZER to create a
	compound literal.
	* tests/test-1.c (main): Use pthread_mutex_init, not
	PTHREAD_MUTEX_INIT for mutex initialization

	* sysdeps/generic/pt-barrier-init.c (pthread_barrier_init): Remove
	assert.  Copy ATTR if non-defaults are used.
	* sysdeps/generic/pt-cond-init.c (pthread_cond_init): Include
	<string.h>.  Remove assert.  Copy ATTR if non-defaults are used.
	* sysdeps/generic/pt-mutex-init.c (_pthread_mutex_init): Cast
	PTHREAD_MUTEX_INITIALIZER to create a compound literal.
	* sysdeps/generic/pt-rwlock-init.c: Include <string.h>.
	(_pthread_rwlock_init): Cast __PTHREAD_RWLOCK_INITIALIZER to
	create a compound literal.  Copy ATTR if non-defaults are used.

	* sysdeps/generic/pt-cond-timedwait.c
	(__pthread_cond_timedwait_internal): Check that ABSTIME->TV_NSEC
	is valid.  Don't shadow ERR.  Don't return before cleaning up.
	* sysdeps/generic/pt-mutex-timedlock.c (pthread_mutex_timedlock):
	Move after __pthread_mutex_timedlock_internal.  Check that
	ABSTIME->TV_NSEC is valid.
	* sysdeps/generic/pt-rwlock-timedrdlock.c
	(pthread_rwlock_timedrdlock): Move after.
	__pthread_rwlock_timedrdlock_internal.
	(__pthread_rwlock_timedrdlock_internal): Check that
	ABSTIME->TV_NSEC is valid.
	* sysdeps/generic/pt-rwlock-timedwrlock.c
	(pthread_rwlock_timedwrlock): Move after
	__pthread_rwlock_timedwrlock_internal.
	(__pthread_rwlock_timedwrlock_internal): Check that
	ABSTIME->TV_NSEC is valid.
	* sysdeps/generic/sem-timedwait.c (__sem_timedwait_internal):
	Check that TIMEOUT->TV_NSEC is valid before enqueuing the thread.

	* sysdeps/generic/pt-rwlock-rdlock.c
	(__pthread_rwlock_timedrdlock_internal): Fix declaration.

	* sysdeps/generic/pt-mutex-trylock.c (__pthread_mutex_trylock):
	Don't return EDEADLK.  POSIX does not allow it.

	* sysdeps/mach/pt-timedblock.c (__pthread_timedblock): Calculate
	the relative timeout without overflowing.

	* sysdeps/mach/hurd/i386/pt-setup.c (stack_setup): Cast THREAD.
