Avoiding "unused variable" warnings

I think I have seen it somewhere but forgot.

Is it possible to create a noop macro that makes compiler believe macro
arguments are used? I mean the case of debug macro that for debug off is
redefined as something like do { } while(0) but then if arguments are used
for debugging purposes only compiler emits warning. Some people do not like
it :)
