Well, in the meantime we apparently have to live with it. Unless Will
is using some unreleased gcc version that nobody else is using and we
can just ignore it?

Yes, he is using gcc-7 that is unreleased. (It will be released April
next year.)

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.
