Given that this patch (hopefully) fixes a problem in the current net-2.6.24
tree, I'm inclined to slip it into mainline immediately.
But I'd like a better description, please. Which "non-gcc parser" are we
talking about here? Something under ./scripts/. Well, please identify it,
and describe what the problem is, and how the proposed patch will address
it.
Let's cc Sam too, as I guess he's the guy whose code just broke.
Thanks.
(patch retained for cc'ees)
