OK, the configure test is:

AC_TRY_LINK([#include <pthread.h>],
[pthread_t th; pthread_join(th, 0);
pthread_attr_init(0); pthread_cleanup_push(0, 0);
pthread_create(0,0,0,0); pthread_cleanup_pop(0); ],
[acx_pthread_ok=yes], [acx_pthread_ok=no])

Seems we can't just jump in there and grab stderr so I added the
following code to CVS which should do the trick.
