4552 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
4553 targ-map.o, and run are built. They are now built in the
4554 individual simulator directories, taking sources from ../common as
4555 necessary. This replaces the merging of libcommon.a into
4556 linsim.a, which was problematic for the WinGDB build process.

4604 number is zero (ie no signal).

4608 * run.c (main): Print out if the program raised a signal.
