Microsoft licensing Unix source code. Soon the four horsemen will appear. :)
But anyway, didn't Microsoft use FreeBSD Unix code in NT? So Microsoft is just trying to get legit and use Unix code without getting sued by SCO like IBM did. Obviously the next Windows will use some SCO Unix code in it. Too bad, I thought it was going to be re-written by scratch.
Shades of Xenix, Microsoft is dealing with SCO again!
