I just checked my copy of K&R2.  It does indeed use different parameter
names in the declaration and in the definition.  I have no idea why; I
can't think of any good reason for it -- but as I've said it's perfectly
legal.  (It might have been useful as a way to illustrate that very
point, but there's no explicit mention of it.)
