An ATTRIBUTE_UNUSED shouldn't cause problems if the parameter is actually
used.  At least that's been my understanding.  I've always been under the
impression that it meant the varable/parameter *might* be unused, not that
is absolutely is unused and you can optimize based on that information.

Is that not the case?  Can someone verify?
