- * Playing games with sigreturn.   Check if calling sigreturn from a
- * signal handler screws anything up.
- *
- * Run with:
- *	-a:	use an alternate signal stack
- *
- *	-b:	call sigreturn from outside of a signal handler
- *		An error is OK
- *
- *	-c:	clobber the sigcontext before calling sigreturn
- *		the program should die
- *
- *	-f:	don't use sigreturn -- fall through the signal handler
- *		-c, and -i options ignored when used
- *
- *	-i:	call sigreturn from a function called by the signal handler
- *
