Which is both appreciated and understandable. I suppose you agree
though that if you were to follow the model used for the kexec part,
things would quickly become unwieldy. Hence I would strongly
suggest considering to introduce Linux'es or a Linux-like configure
mechanism before continuing to make code conditionally compilable.
