This actually is just a warning in VC7, and never came up in MinGW, so I
didn't pay much attention to it.  But why wouldn't it be able to cast, is it
a 32 or 64-bit system?

Could you modify your copy of identifiable.hpp, and replace:

    return reinterpret_cast<unsigned int>(p.get());

with

    return p.get() - (char*)0;

This may fix the problem (at least it removes the warning in vc71).
