Yep, thats right. I actually managed to figure that part out after looking more
closely at what debug_tree was telling me. 

Now it finds the method index fine, but later gets "internal error in
check-init: tree code not implemented: record_type", which I guess means that I
cant stick the `iface' directly into lookup_arg.

Do I have to do something similar to what is done for "dtable"?:

  dtable = build1 (INDIRECT_REF, dtable_type, dtable);
  dtable = build (COMPONENT_REF, class_ptr_type, dtable,
		  lookup_field (&dtable_type, class_ident));
