The way it is related is that the CWG has introduced the concent of
linkage for type -- which did not exist in ARM and existed only for
function type in C++98/03 and the unnamed enum no longer has an
external linkage.  As I said on fr.comp.lang.c++, I brought the issue
to the C++ committee and I think the issue should not be closed.

The answer I gave you was much more detailed and accurate that what
you report here :-) -- in particular, the ocmpiler is attempting to do
overload resolution and it is in the phase of constructing the
overload set that the error appears.  But, the whole thing is confused
:-)
