// taking no parameters and returning TInt. This is not really valid as a thread
// function which takes a TAny* parameter which we need.
//
// So the DLL entry-point WinsMain() is used to return a TInt representing the
// real thread function within the DLL. This is good as long as
// sizeof(TInt)>=sizeof(TThreadFunction).
