You're right about (a) and I agree with you about (b) in
priciple, but I have to disagree in this specific case because of
the nature of warnings in Vax C.  The fact that a warning was
issued is recorded in the object file and reiterated every time
you do anything with it like put it in a library or link to it.
Vax C has another category of messages (informational) which are
displayed, but not recorded in the object file which would be
more appropriate for this kind of message.
