I checked in this patch (orignally posted January 23):
2002年02月22日 Per Bothner <per@bothner.com>
	* class.c: Change vtable to be more compatible with g++ v3 abi.
	(get_dispatch_table): Prepend offset-to-top (always 0) and
	type_info pointer (currently unimplemented hence NULL) to vtable.
	Specifically, prepend offset-to-top and typeinfo ptr (currently null).
	(make_class_data): Variable dtable_start_offset is sizeof 2 pointers.
	Adjust vtable pointers by dtable_start_offse - i.e. skip new words.
	(build_dtable_decl): Add declarations for new fields.
