template< class Iterator >
typename reverse_iterator<Iterator>::difference_type 
    operator-( const reverse_iterator<Iterator>& lhs,
               const reverse_iterator<Iterator>& rhs );
 (until C++11) 
template< class Iterator1, class Iterator2 >
auto operator-( const reverse_iterator<Iterator1>& lhs,
                const reverse_iterator<Iterator2>& rhs ) -> decltype(rhs.base() - lhs.base());
 (since C++11)
