Yeah, Microsoft just uses everyone elses code, but Intel, SGI and Cambridge Uni prolly know about that code being used, unless Microsoft ran around looking for leaked code and hacking their allies (in Intel's case) corporate servers...
By the way Kintaro, don't ever mention that you've looked at that code to any open source project leaders. Most of them would no longer touch you with a ten foot pole. Happened to me when I downloaded it.
You probably shouldn't tell Microsoft either
