My thought is that private inheritance maps quite naturally to the
current implementation; there is a private is-a relationship - the
linked list itself may be composed of types of different linked_ptr but
they are easily referenced polymorphically as linked_ptr_base.

I was considering making it protected inheritance as some of the
functions in linked_ptr_base could conceivably be useful to further
derived classes (as could the is-a relationship).  Do you have any
strong feelings on that?
