If I saw this message from a tool, I wouldn't get what it means right away. Can you come up with an easier to read alternative? I can only suggest `multiple statement macro used without braces`, but maybe a more self-documenting message comes to your mind.

While I see your point, this doesn't seem worse to me:

    if (do_increment)
      INCREMENT_TWO(a, b); // `(b)++;` will always be executed.

Up to you though.
