  19  * going to use the Microsoft way and #define the Microsoft-specific
  20  * functions to the unix way. Microsoft use a separate subsystem for sockets,
  21  * but Unix normally just use a filedescriptor on the same functions. It is
  22  * a lot easier to map back to the unix way with macros than going the other
  23  * way without side effect ;-)
