Then use #if 0 and not comments. The point is not to lose information/code
which is presently unused but would be potentially useful later on.

Also ... it would be good to dig in a bit deeper than "oh, variable unused,
let's remove it". There's a chance that it's also the indicator of a bug in the
code.

I would have removed all of those a year ago when I did the big clang analysis,
but didn't because I wasn't 100% sure they were *really* unused.

In case of doubt, I'd much prefer if you contacted the maintainers/authors of
those plugins to make sure those variables are really not needed.
