        * class.c (finish_struct_1): Skip down to the inner type in
        multidimensional arrays.  Ensures ctors will be made for types that

        * decl.c (last_dtor_insn): New to track the last compiler generated
        insn in a dtor.

        vtable setup all the time, if we can.

        * class.c (finish_struct_1): Delay delta fixups for virtual bases
        until after we have done the hard virtuals, to avoid a bogus `every
        virtual function must have a unique final overrider' for virtual
        functions that are only overridden by hard virtuals.

        * decl.c (push_namespace): Rewrite to use build_lang_decl, so we
        get a DECL_LANG_SPECIFIC node.
        * cp-tree.h (lang_decl_flags): Add new member `level'.
        (NAMESPACE_LEVEL): Don't use decl.arguments, instead use the

        * decl.c (poplevel): Handle the merging of subblocks of cleanups
        when finishing blocks that have already been created (usually due to
        the fixup goto code).  Fixes bad debugging information.

        * method.c (hack_identifier): Don't abort when we get a TREE_LIST

        (emit_thunk): Don't call assemble_external.
        (make_thunk): Create thunk as a FUNCTION_DECL so that it
        gets the right mode and ENCODE_SECTION_INFO works.
        
        * parse.y: Use mark_used.  Pass operator names to do_identifier.
        * lex.c (do_identifier): Handle operator names.

        * decl.c (lookup_tag): Return NULL_TREE if we don't find what we are

        * g++.c (WITHLIBC): New macro.
