Conditional compilation with ifndef and || doesn't catch second case

You want:

#if !defined(INTERNATIONAL) && !defined(DEBUG)
    // neither defined - setup Crittercism
#else
    // one or both defined
#endif

Or you can do:

#if defined(INTERNATIONAL) || defined(DEBUG)
    // one or both defined
#else
    // neither defined - setup Crittercism
#endif
