6200 number is zero (ie no signal).
6202 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
6204 * run.c (main): Print out if the program raised a signal.

6233 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
6235 * run.c (main): Always return sigrc at end.
6237 Tue Oct 10 12:03:13 1995 J.T. Conklin <jtc@rtl.cygnus.com>
