Re: move only types in standard containers

I'm trying to use a type that is moveable, but not copyable, in a
standard container, in this case an unordered_map. When I try to
insert it, I get complaints about a deleted copy constructor. I
thought that move only objects were supported in standard containers?

Here's my type:

struct session_t {
     session_t() : fd(make_unique_fd(0)) {}
     session_t(const session_t&) = delete;
     session_t& operator=(const session_t&) = delete;
     session_t(session_t&& session) : fd(move(session.fd)) {}
     session_t& operator=(session_t&& other) {
         if (this != &other) {
             fd = move(other.fd);
         }
         return *this;
     }

     unique_fd fd;
};

typedef unordered_map<int, session_t> session_map;

Heres where the error pops up:
map.insert(make_pair(*session.fd, move(session)));

Testing on GCC 4.4
