2161         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in

2163         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
2164         targ-map.o, and run are built.  They are now built in the
2165         individual simulator directories, taking sources from ../common as
2166         necessary.  This replaces the merging of libcommon.a into
2167         linsim.a, which was problematic for the WinGDB build process.
2168         * run.c:  Include config.h from . instead of ../common.

2201         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
2202         Add support for incomplete h8/300 termination indicators.
2203         (usage): Make more verbose.
