On the other hand, in a hairy C program of mine I have defined a counter

Not every problem is worth using a sledgehammer to deal with.
The alternative is then to do as I think Go has done, and turn unused
variables into errors. And then you need a way (like a pragma) to locally
disable this error when you are debugging (and this is not nice), or when you
generate code automatically (this is acceptable).
I've used pragmas to turn of warnings before. Sorry, but "bleh".
