Turn on "require function prototypes", or whatever the warning option is
called in CodeWarrior. Notice all the warnings you get.
Look up _default argument promotions_ in your C reference book to see
why the absence of a prototype makes a huge difference when you're
trying have a parameter that's smaller than an int.
