class.c (finish_struct_1): Use OVL_CURRENT on TREE_VEC_ELT.

	* class.c (finish_struct_1): Use OVL_CURRENT on TREE_VEC_ELT.
	* decl2.c (constructor_name_full): Likewise.
	* tree.c (mapcar): Add OVERLOAD support.
	* init.c (resolve_offset_ref): We must use basetype_path before we
	destroy it with a call to convert_pointer_to.
