Indeed it should, but I think we're Ok anyway. Here's the extract from
the SDK headers.

/** This is used instead of -1, since the* SOCKET type is unsigned.*/
#define INVALID_SOCKET  (SOCKET)(~0)
#define SOCKET_ERROR            (-1)


But it might be worthwhile going across all those places and setting
them to PGINVALID_SOCKET, and typedef that as well.
