	PR 1855/cpukit
	* Makefile.am, configure.ac: 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.
