I've been seeing that for some time with gcc 2.95.3, so it's not exactly
a new issue.  I've not seen it with modern versions, but I'm not sure
why not.  What it's unhappy about is the "errhint(hint)" calls, which
I agree with it are dangerous on their face.  Maybe you're 100% sure the
hint strings will never contain percent marks, but I'm not.
