Make sure you declar all templates before referring to them:

template <typename content> class ll;
template <tyepname content> class ll_iter;
template <typename content> class ll_element;

And then you declare

> template<class content> ll_element {
                         ^^ class keyword missing

>   friend ll_iter<content>;  
          ^^ I'd advise you to add class keywords here to, but I'm not
sure these are required.
