This isn't just using GPL'ed headers, it's distributing GPL'ed
headers as part of the LLVM source tree.

Clearly we have to compile against kernel headers, but I don't know
what effects copying GPL'ed code into LLVM (and committing it there)
has on LLVM's license obligations.

Obviously, IANAL :).  You're saying the GPL doesn't restrict this
kind of copying?

Shouldn't LICENSE.TXT at least be updated?
