We're not writing POSIX applications here - this is a diagnostic tool so if we are running on linux we need to expose them. If we've got linux C libraries that don't provide feature macros for the fields in the linux_dirent eposed by readdir(3), then I guess we're stuck with having to play autoconf games, eh?
