A16-0-1 Use #define for conditional file inclusion?

[kent.dorfman766]

I too have issue with the rules regarding the preprocessor directives in my line of work. Much of what I do is interfacing higher level algorithmic C++ code with POSIX API system functions, and my wrapper classes are about 90% non-compliant. Frequently running into violations surrounding the concept of "system frameworks" and reusable libraries. If I generate a shared utility library .so then I can pretty much guarantee that not ever class/method in it will be used in the target application.

The OP example is extremely relevant when designing platform portable code for multiple embedded environments.
