Another alternative would be autoconf check?
#if (defined (__unix__)                                                 \
     || (defined (__Apple__)                                            \
         && defined (__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__)     \
         && __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ >= 101000))
// Autoconf test?
#define HAVE_FSTATAT 1
#else
#define HAVE_FSTATAT 0
#endif

Your patch is fine, if you'd like to apply it.   I'd not noticed it go by :(
