This is a fairly annoying bug in VC++ where it complains about a bogus
ambiguity. The really nasty part is that it is situation dependent,
which is why we didn't pick this up with our tests.

Anyway, I've qualified the affected names which should work around
the problem. Can you give the bug fix a try and let me know if
there are still any problems?
