Ok. That actually looks like a valid use of the C function argument
array passing semantics. It's rather much simpler than exposing the
pointers.

So I guess we don't really end up wanting to disallow this, and the
new gcc array sizeof warning is good enough.

Thanks for running the analysis so that I didn't have to look at it ;)
