Thanks. I changed the map to:
typedef map<session_id, boost::function<long, Y*, X*> > MyMessageMap;
No errors but enough warnings to choke a horse. Have I just been nailed by
VC6SP4? If so, I think I'll just give up and map the session-ids to Y*s.

Thanks in advance for any suggestions.

Please respond
to Boost-Users
I think the best solution for you would be to put boost::function<short>'s
in your map. Look at the example in the bind documentation at
http://www.boost.org/libs/bind/bind.html#with_boost_function
