Yeah, sorry, I meant `used`, i.e. it is that one the one that
constraints the combination rather than `unused`.

>From a quick look at the links in `compiler_attributes.h`, `unused`
can also be applied to types, while `used` cannot -- it is another
difference, but your sentence above already implies it anyway. :)

Thanks for the correction!

Cheers,
