The scoped_ptr is defined to be simple and to load as little as
possible the code using it. To uses all potimizations possible, it's
been designed in such a way that the struct pointed byt it must be
completely defined when the pointer is declared, so you should replace
the forward declaration "class C>Peer;"  with the full declaration
(typically, ibcluding its corresponding header
