Comment (by johnmaddock):

 If you add the following before including the Eigen headers does it fix
 things?

 {{{
 namespace boost { namespace multiprecision {

    template <class Backend, class tag, class A1, class A2, class A3, class
 A4>
    inline number<Backend, et_on> min(const number<Backend, et_on>& arg,
 const detail::expression<tag, A1, A2, A3, A4>& a)
    {
       number<Backend, et_on> t(a);
       return (std::min)(arg, t);
    }
    template <class tag, class A1, class A2, class A3, class A4, class

 A3, A4>& arg, const number<Backend, et_on>& a)
    {

       return (std::min)(arg, a);
    }
    template <class tag, class A1, class A2, class A3, class A4, class

       return (std::min)(arg, a);
    }
