Hi,

Sorry for the n00b question, but I'm trying to serialize some unsigned 
__int64 member variables using boost::serialization.

I added the following to my header:

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

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

But the compiler still complains that it doesn't know how to handle that 
right-hand operand.

Is there something obvious here I'm missing?

Thanks
