Out of curiosity, I just googled around and found some code samples: https://www.google.com/#q=David+Cutler+davec+site%3Apudn.com...
There's actual kernel code in here, reading this code could most likely prevent from working on WINE or ReactOS and who knows what else could apply under your jurisdiction.
It's funny that his code is right there for us to see, but we shouldn't see it!
