6485         (callback.o,targ-map.o): Delete, moved to Make-common.in.
6486         (gentmap,targ-vals.h,targ-map.c): Likewise.
6487         (run-autoconf): Delete.
6488         * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
6489         (common makefile fragment): Moved back into ...

6507         * (distclean):  Remove targ-vals.def.
6508
6509         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
6510         into here.  Makes insertion into makefiles easier.  Also, change
6511         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
6512         targ-map.o, and run are built.  They are now built in the
6513         individual simulator directories, taking sources from ../common as
6514         necessary.  This replaces the merging of libcommon.a into
6515         linsim.a, which was problematic for the WinGDB build process.
6516         * run.c:  Include config.h from . instead of ../common.

6548         Parse program name from argv[0] and use in error messages.
6549         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
6550         Add support for incomplete h8/300 termination indicators.
6551         (usage): Make more verbose.
6552         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
