I think this patch is OK.  As you say, we could also change 
reference_binding or initialize_reference, but the general policy in the 
front end has been to resolve single OVERLOADs at the point of lookup. 
In fact, if we were you going to make a more substantial change here, it 
would probably be to have the USING_DECL record only a FUNCTION_DECL, 
rather than an OVERLOAD.

This is OK, too, though I would prefer using error_operand_p to the 
direct comparision with error_mark_node.  In this case, error_mark_node 
is probably correct -- but using error_operand_p for expressions is more 
mnemonic.

Thanks,
