+ pthread: check for pthread_create, not pthread_join
+ * m4/pthread.m4 (gl_PTHREAD_CHECK): Check for pthread_create, not
+ pthread_join. On FreeBSD 9, pthread_create is in libpthread but
+ pthread_join in libc. I hope this removes the need for all the
+ OSF/1 5.1 pthread_join business. Reported by Richard Yao in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2012-07/msg00042.html>.
