That won't help as-is, because it *does* have sigwait, just not with
the POSIX API. thread_test.c does this:
/* Test for POSIX.1c 2-arg sigwait() and fail on single-arg version */
#include <signal.h>
int sigwait(const sigset_t *set, int *sig);
which perhaps should be pulled out of there and moved to the
configure script proper.
