Here are the two reasons why one deals with this:

    1) Having put an exit() in the program, you should add
       /*NOTREACHED*/ right after it; this tells lint that you know
       what you are doing.

    2) If you do 1), as you should, getting the lint message means you
       screwed up: you didn't put an exit() or return where it
       belongs.

In short, if you are in the habit of ignoring this particular message,
you should change your habit. Always do 1) and, should you get the
message, investigate and fix the problem.
