7201         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
7202         into here.  Makes insertion into makefiles easier.  Also, change
7203         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
7204         targ-map.o, and run are built.  They are now built in the
7205         individual simulator directories, taking sources from ../common as
7206         necessary.  This replaces the merging of libcommon.a into
7207         linsim.a, which was problematic for the WinGDB build process.
7208         * run.c:  Include config.h from . instead of ../common.

7241         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
7242         Add support for incomplete h8/300 termination indicators.
7243         (usage): Make more verbose.
7244         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
