* The [0-0] bracketed expression will work as expected, but it's
somewhat unusual :) Is it intentional?

* If it's a typo, are you okay if I replace it with a plain 0 on commit?

* Also, IIRC, Olaf considered pre-4.0 gcc releases as well (rejecting
them of course), which is sort of meant as part of "gcc-4.3 and
earlier". But, given your extensive testing with old distros (thanks for
that!), I think it's safe to ignore pre-4.0 gcc releases altogether.
