Using gcc 4.5.2 20101125 (prerelease), the only additional issue is that
gcc45 doesn't like the unused "dummy" functions used as guards for
#ifndef <feature-we-want> in:
I'm guessing that the dummy function is needed for linking with some
non-gnu environments, but I'm outside my comfort zone with that guess.
I'm inclined to create a __GNUC__-guarded UNUSED function attribute for
those.
