Correct. lint isn't able to differentiate between sensible code and not. Which

maintaining a permanent patch against the file. I don't think it's too ugly to
not apply.

My apologies, I didn't notice this from forward-porting the patch.

Yes, all the public headers need to be compiled with Sun CC as well.
Unfortunately 'unused' is one of the GCC attributes they haven't implemented
yet.
