Yes.

I prefer to do it this way instead of encasing the variable declaration into 
another #ifdef ... #endif section. This is used in many cases in the Linux 
kernel btw. Here the macro "__maybe_unsed" is defined to 
"__attribute__((unused))".

So what should I do now? Should I revert to another #ifdef in the variable 
declaration? Or is the current version ok?

Thanks.

Best regards,
Stefan
