No, you need to do something like (one more thing I forgot to mention):
 lookup_arg = tree_cons (NULL_TREE, dtable,
 tree_cons (NULL_TREE, build_class_ref (IFACE),
 build_tree_list (NULL_TREE, IDX)));
build_class_ref takes a tree-node representing a type and turns it
into an expression that will evaluate to (the address of) the
Class for the type.
