Cheers, that seems to work. Now, with the code:
 i = 1;
 for (meth = TYPE_METHODS (iface); ; meth = TREE_CHAIN (meth), i++)
 {
 if (meth == method)
 {
	 idx = build_int_2 (i, 0);
	 break;
	}
 if (meth == NULL_TREE)
 fatal ("internal error");
 }
I'm getting the "internal error". Debugging shows:
(gdb) p debug_tree (meth)
