Test program for const warning bug

> the warning is correct, see http://c-faq.com/ansi/constmismatch.html

Thanks for this link. This does indeed confirm what I said, in much less words
than I needed. Moreover, it points out that the issue doesn't exist in C++.

However, it doesn't explain why the issue still present in C.

Any insights into this question?

If this is just to keep some paper-pushers happy, maybe we could keep the
current behavior as the default, but have a -W flag to make gcc mimic g++'s
behavior?
