The C Users Group had a real nifty way of doing this with conditional
macros to either get the value macro or the message macro, but I
tossed it on my "neat-stuff-I-gotta-try" stack and can't find it
right now. I'll look for it for you if you want.
The thing that really struck me as neat about the method is that it is
very easy to keep the right error values with the right error messages.
