for VC6 we'd generate the friend functions in the global namespace so they
can be found without koenig lookup but by the (disallowed) normal lookup
rules.

I think there is a way to generate the functions in boost::python for VC6
and look them up using a dispatching function template, but it hardly seems
worth it since it wouldn't work properly for GCC.
