4589 individual simulator directories, taking sources from ../common as
4590 necessary. This replaces the merging of libcommon.a into
4591 linsim.a, which was problematic for the WinGDB build process.

4639 number is zero (ie no signal).

4672 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
4674 * run.c (main): Always return sigrc at end.
4676 Tue Oct 10 12:03:13 1995 J.T. Conklin <jtc@rtl.cygnus.com>
