6207 number is zero (ie no signal).
6209 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
6211 * run.c (main): Print out if the program raised a signal.

6235 generic. Also updated to only load relevant sections. Moved

6240 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
6242 * run.c (main): Always return sigrc at end.
