Oh, right. We do that largely so that the builds on our Tinderbox use the
stricter rules so we notice changes that cause problems. Maybe we should
reconsider this if we want it to be easy for people to build from source
RPMs and find some other way of making the Tinderbox RPM builds use the
stricter warnings as errors.

This warning is due to an error in the glibc headers as you say. The version
I have is glibc-devel-2.2-9, and it does not have this problem.
