Good idea. So I tried it, and indeed this patch 
 
2005-05-10  Nathan Sidwell  <nathan@codesourcery.com> 
 
	PR c++/20723 
	* pt.c (more_specialized_fn): Member functions are unordered wrt 
	non-members.  Conversion operators are unordered wrt other 
	functions. 
 
	PR c++/19203, implement DR 214 
	* call.c (joust): Use more_specialized_fn. 
	* cp-tree.h (DEDUCE_ORDER): Remove. 
	(more_specialized): Replace with ... 
	(more_specialized_fn): ... this. 
	* pt.c (maybe_adjust_types_for_deduction): Remove DEDUCE_ORDER 
	case. 
	(type_unification_real): Remove DEDUCE_ORDER case. 
	(more_specialized): Replace with ... 
	(more_specialized_fn): ... this.  Implement DR 214. 
	(most_specialized_instantiation): Use get_bindings_real directly. 
 
to the 4.0 branch has caused the problem. It may be conjectured that the 
corresponding patch broke the same thing on mainline. 
 
That's bad -- we now have a regression between 4.0.0 and 4.0.1 :-(
