--- Comment #6 from Roger Wolff <R.E.Wolff at BitWizard dot nl> ---
So, I've added "-Wall" to my Makefile to get ALL warnings, giving me the
biggest chance of finding bugs through the compiler telling me you have a bug
on line X of file Y. 

So IMHO -Wnull-dereference should be part of -Wall. I'm not a compiler guy. I
just use the stuff. So now the question becomes: Why is that warning not part
of -Wall ?
