configure promise + new seg faults

[Stefan Böhringer]

Finally I tracked down my recent problems.

I figured that GSConfig.h was empty - and that I now have to run
configure in each of the core components. The promise of having to
configure only once in make seems to have gone. Such changes should be
clearly announced on the list IMHO.

With a current cvs checkout DO messages now result in segfaults. Does
anybody else see this as well?

Thanks,

        Stefan
