  42 /* To hide the platform differences between MS Windows and Unix, I am
  43  * going to use the Microsoft way and #define the Microsoft-specific
  44  * functions to the unix way. Microsoft use a separate subsystem for sockets,
  45  * but Unix normally just use a filedescriptor on the same functions. It is
  46  * a lot easier to map back to the unix way with macros than going the other
  47  * way without side effect ;-)
