I was working on some tests for the the boost components I've been working
on and came across this issue.

If an object is initialised with a class that is a sub class of another a
compiler error results, though I'm not sure if this is a specific problem
with VC6:

ie

#include ...

class c1 {
public:
    c1() {}
    class c2 {
    public:
        c2() {}
    };
    c2 t;
};

...

int main(int argc, char* argv[])
{
    c1 x;
    object o(x.t);
    return 0;
}

will result in:

boost\python\object_core.hpp(220) : error C2275: 'c1::c2' : illegal use of
this type as an expression
        test.cpp : see reference to function template instantiation
'__thiscall boost::python::api::object::boost::python::api::object(const
class c1::c2 &)' being compiled

Line 220 is the object constructor, but I'm not sure what part of it the
compiler is objecting to.
