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

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