35		This means that we shouldn't rely on PIDs and file descriptors
36		being the same type, so we have to describe processes with a struct,
37	<	instead of the original int[3]. To keep things simple, we typedef
38	<	the posix pid_t on those systems that don't have it already.
33	<
34	<	Some older Windows systems use negative PIDs. Open_process() and
35	<	close_process() will convert those to positive values during
36	<	runtime, so that client modules can still use -1 as invalid PID.
37	>	instead of the original int[3]. For that purpose, we typedef a
38	>	platform independent RT_PID.
