[Openmp-dev] OS definitions

That would seem to be the case since there are other places that have stuff like

#if (KMP_OS_LINUX && !KMP_OS_CNK)

Which is why I was proposing KMP_OS_DIALECT_CNK. (Or maybe KMP_LINUX_DIALECT_CNK would be even better).

Did you test that? As I recall, CNK pretends to be Linux, so KMP_OS_LINUX is already defined on CNK.
