For conditional inclusion,C99 document says:
        Only the first group whose control condition evaluates to true
        (nonzero) is processed. If none of the conditions evaluates to true,
        and there is a #else directive, the group controlled by the #else is
        processed; lacking a #else directive, all the groups until the
        #endif are skipped.1
In my understanding,the skipped part should NOT be processed.
