So you are saying here that configure DOES find the timespec struct, correct?

Now I'm confused. If it does not exist, how did configure find it?

That (i.e. not to make assumptions) is exactly the purpose of
configure. If possible, it is nicer to have a feature-based test that
works on all platforms, than OS-specific checks (#ifdef WIN32 ...).
