	* Makefile.am, configure.ac, psx16/Makefile.am: Correct signal
	processing during pthread_join. We are supposed to unblock the thread
	waiting on a pthread_join(), dispatch the signal handler, account for
	it potentially overwriting errno, and then have the thread return to
	blocking within pthread_join().
	* psxeintr_join/.cvsignore, psxeintr_join/Makefile.am,
	psxeintr_join/init.c, psxeintr_join/psxeintr_join.doc,
	psxeintr_join/psxeintr_join.scn: New files.
