Thanks for providing the mandatory information about the host platform 
accidentally as part of the compiler error message... ;)

To my knowledge VBoxSDL never worked reasonably well on Darwin, so this 
doesn't get tested at all. Obviously it doesn't even build successfully, 
as there is no implementation of the GetWinId method for this platform.
