Reported by Arnold Robbins <arnold@skeeve.com>. * lib/setlocale_null.c (c11_threads_in_use, pthread_in_use): New macros, copied from lib/glthread/lock.h. (pthread_mutex_lock, pthread_mutex_unlock): Mark as weak. (setlocale_null_with_lock): If pthread_in_use() is false, use setlocale_null_unlocked directly. * m4/threadlib.m4 (gl_WEAK_SYMBOLS): New macro, extracted from gl_THREADLIB_BODY. Define HAVE_WEAK_SYMBOLS. (gl_THREADLIB_BODY): Invoke gl_WEAK_SYMBOLS. * m4/setlocale_null.m4 (gl_FUNC_SETLOCALE_NULL): Invoke gl_WEAK_SYMBOLS. Set LIB_SETLOCALE_NULL to empty if weak symbols are supported. * m4/duplocale.m4 (gl_FUNC_DUPLOCALE): Add comment.
