The error is in this part ;

template <class T, class U, class B = operators_detail::empty_base<T> >
struct equality_comparable2 : B
{
     friend bool operator==(const U& y, const T& x) { return x == y; }
     friend bool operator!=(const U& y, const T& x) { return !static_cast<bool>(x == y); }
     friend bool operator!=(const T& y, const U& x) { return !static_cast<bool>(y == x); }
};

Any help please ?????
