open4 will not work on Windows -- it is a Unix only library.For
Windows there is popen4.

It does the same thing ... but for Windows. Be forewarned that the
possibility of blocking the program on a full pipe is very possible on
the Windows platform. Ara and Tom Pollard had a good discussion about
this last Thanksgiving.
