 329         targ-map.o, and run are built.  They are now built in the
 330         individual simulator directories, taking sources from ../common as
 331         necessary.  This replaces the merging of libcommon.a into
 332         linsim.a, which was problematic for the WinGDB build process.
 333         * run.c:  Include config.h from . instead of ../common.
