Yeah; I deliberately left that callback weakly typed, because it seemed
that the alternative was to expect every caller to cast, which would
effectively disable any error checking you might hope to get anyway :-(

Agreed.  That extern is pretty bogus in itself...

-Wbad-function-cast might possibly be interesting, although I'm afraid
it would be likely to barf on some of our Datum<=>pointer conversions.
