It would be nice to get a warning for the code below when bar is used.
Using something documented as unused is likely a bug.
void
foo (int __attribute__((unused)) bar)
{
bar++;
}

I think there was another bug about this and it was closed because we use unused to mean it might be
unused not that it is just unused.

unused is really a marker for maybe unused and that is it.
