5467

5469
5470 * Makefile.in (libcommon.a): Delete.
5471 (callback.o,targ-map.o): Delete, moved to Make-common.in.

5497 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5498 targ-map.o, and run are built. They are now built in the
5499 individual simulator directories, taking sources from ../common as
5500 necessary. This replaces the merging of libcommon.a into
5501 linsim.a, which was problematic for the WinGDB build process.
5502 * run.c: Include config.h from . instead of ../common.
5503 * Make-common.in: Remove. It's no longer necessary.

5575
5576 * run.c (main): Removed SH specific comments, so source is
