Thanks Steve, I tried that but I'm still getting no joy ...

Could it be that unsigned __int64 is not a class, but an integral data type?

I have two typedefs of unsigned __int64 type: TimeCode and FileSize. I'm 
assuming the compiler is smart enough to infer the difference.

I've changed my source according to the docs:

namespace boost
{
    namespace serialization
    {

        template<class Archive>
        void save(Archive & ar, const unsigned __int64& big, unsigned 
int version)
        {
            ar & sizeof(big);
            ar.save_binary(&big, sizeof(big));
        }

        template<class Archive>
        void load(Archive & ar, unsigned __int64& big, unsigned int version)
        {
            size_t size = sizeof(big);
            ar.load_binary(&big, size);
        }

    }
};

BOOST_SERIALIZATION_SPLIT_FREE(unsigned __int64)

And it still complains with
