[odb-users] MSVC Compiler Error C2872 when comipling a project using ODB with a polymorphic heirarchy

[Jordan J. Neuhart]

Boris,

Just out of curiosity, what did you have to do to fix this bug, just in
case I run into it again later?  

Thanks,
Jordan

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?
