	[BZ #21804]
	* sysdeps/nptl/bits/thread-shared-types.h (__PTHREAD_SPINS_DATA)
	[__PTHREAD_MUTEX_LOCK_ELISION && __WORDSIZE == 64]: Remove
	trailing semicolon.
	(struct __pthread_mutex_s): Remove semicolon after
	__PTHREAD_COMPAT_PADDING_MID and __PTHREAD_COMPAT_PADDING_END.
	* sysdeps/hppa/nptl/bits/pthreadtypes-arch.h
	(__PTHREAD_COMPAT_PADDING_MID, __PTHREAD_COMPAT_PADDING_END): Add
	semicolon.
