Ahh, self-built? So it's not part of some experimental ARM distro
setup and this will be annoying lots of people?

If so, still think that we could just get rid of the ____ilog2_NaN()
thing as it's not _that_ important, but it's certainly not very
high-priority. Will can do it in his tree too for testing, and it can
remind people to get the gcc problem fixed.
