 430         individual simulator directories, taking sources from ../common as
 431         necessary.  This replaces the merging of libcommon.a into

 433         * run.c:  Include config.h from . instead of ../common.

 467         Add support for incomplete h8/300 termination indicators.
 468         (usage): Make more verbose.
 469         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
