Try dropping the ::type after result_of::size<T>,

    static const int N = boost::mpl::eval_if<
        bindings::has_static_size< double[10] >,
        bindings::result_of::size< double[10] >,
        boost::mpl::int_<0>
    >::type();

    std::cout << N << std::endl;

    static const int J = boost::mpl::eval_if<
        bindings::has_static_size< std::vector<double> >,
        bindings::result_of::size< std::vector<double> >,
        boost::mpl::int_<0>
    >::type();

    std::cout << J << std::endl;

this happens to compile and work on my system.
