It is indeed an operator.  `operator' and `keyword' are not mutually
exclusive (although, as it happens, this is the only C keyword that is
also an operator).  (In Pascal, e.g., the keywords `div' and `mod' are
operators.)

I agree with the latter sentiment, although I see this as a relatively
minor issue.  (There are things that the draft seems to say that I find
even less obvious than this---e.g., Arthur Olson's observations on reserved
names.)
