Yes, there is, but it is more error prone (because then you are hiding
the warning instead of saying it is unused with a safeguard against any
use). I would not call this an hack, because __attribute__ is a well
known, well used gcc mechanism. For people not using gcc, it would not
change anything.

Maybe there are another more portable methods I am not aware of, though.
