 813         targ-map.o, and run are built.  They are now built in the
 814         individual simulator directories, taking sources from ../common as
 815         necessary.  This replaces the merging of libcommon.a into
 816         linsim.a, which was problematic for the WinGDB build process.

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