5615 individual simulator directories, taking sources from ../common as
5616 necessary. This replaces the merging of libcommon.a into
5617 linsim.a, which was problematic for the WinGDB build process.

5665 number is zero (ie no signal).
5667 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
5669 * run.c (main): Print out if the program raised a signal.
