+	* sysdeps/unix/sysv/linux/x86_64/bits/pthreadtypes.h: Define x32
+	__SIZEOF_PTHREAD_XXX_T.
+	(__pthread_internal_list): Check __x86_64__ instead of __WORDSIZE.
+	(pthread_mutex_t): Likewise.
+	(pthread_rwlock_t): Likewise.
+	(__PTHREAD_RWLOCK_INT_FLAGS_SHARED): New.  Defined if __x86_64__
+	is defined.
