Rule 2.5 unsued macro definition
#1
Hi,

I have the following code:

Code:
cfg.h:
/* uncomment next line if the feature is needed for your project */
/* #define activate_feature */

-----
feature.h:
#ifdef activate_feature

#ifdef protected_feature
/* limited visibility stuff */
[...]
#endif /* protected feature */

#endif /* activate feature */

-----

feature.c:
#define protected_feature

#include "cfg.h"
#include "feature.h"

#ifdef activate_feature
[...]
#endif /* activate feature */

The code is part of a library which is used in various projects which shall be MISRA2012 compliant.
Based on each project a different version of cfg.h is used which configures the project specific needs.
In projects where activate_feature is not defined I always got a claim from my code checking tool that the macro protected_feature is not used.
Is this really a violation of Rule 2.5 or is the code checker wrong?
If it is a violation how to handle code where parts a selected by conditional compiling?
