It's different from the case where a K&R definition was seen and thus
type information is present via that mechanism.  We don't want to
warn in that case.

As I suggested, the warning should just print "without a prototype"
but "prototype" here means that a definition before the call is
enough to make us happy (as opposed to -Wstrict-prototypes which
warns about function definitions without a previous prototype we
want to warn about calls to functions without a definition or a prototype).

Any better suggestion?
