// DllEntryPoint is responible for connecting to and disconnecting
// from the 16-bit DLL. This can also be done from an executable,
// by passing to xxxx_ThunkConnect32 a last parameter of
// DLL_PROCCESS_ATTACH on connect and DLL_PROCESS_DETACH on disconnet.
// Failure to disconnect from the 16-bit DLL leaves the 16-bit DLL in
// memory after the process has completed.
