Charles-François Natali <neolo...@free.fr> added the comment:
Here's a patch adding a configure-time check. Since the functions are
checked without being linked explicitely with pthread, it should do
the trick (I couldn't test it on OpenBSD though).
I also added a skipTest to test_posix.test_sched_priority().
