Yes - on some platforms socklen_t is an int, and on others an unsigned int.  It appears in these cases 'int' has been written rather
than socklen_t. So this code will work on some setups, but complain on others.

I don't have time right now to fix this myself, but I've sent this mail to the developers list so hopefully one of them can pick
this up.
