Indeed: I've just removed the Solaris 10 sections from there. Besides, as I've said this is not just a gcc problem: while you're using that version of coreutils on Solaris 10, you won't get any useful work done. Nobody can reasonably expect all affected projects to include a warning against that in its install docs.
