Am I correct to assume that this should shut up warnings for the ifdef case?
Yes.
If so, it still seems to be a somewhat rude way to do it. How long will it take the gcc maintainers to produce a "warning: unused variable is used" warning? ;)
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
