But, but. That would never happen to anyone (hides).

Yea, agreed. I also don't think we want to adopt all of C99 at once, but
rather do it piecemal. Feature by feature.

I'd worked on setting up a modern gcc (or was it clang?) with the
appropriate flags to warn about !C89 stuff some time back, but failed
because of configure bugs. I think Robert has committed most of the
fixes since, and I now actually could do the rest one of these days...
