Whoops. I knew I missed something with that Dispatcher stuff back when I
prepared the sources for LGPL release. Thanks for the hint.
Please have a look at the Dispatcher.c file now where I have put explicit
Create/Delete function to generate/cleanup the subclasses stuff. That should
hopefully solve the MorphOS problem. Please give it a spin.

Hmm. I have to admit that I am not completly uptodate with how MorphOS is
dealing with that all today. Back when I wrote SDI_hook.h together with Dirk
Stoecker it was more or less the only way to do that.
But please feel free to propose a change here. What exactly would you change
in SDI_hook.h? Please show some examples prior to changing SDI_hook.h

Until that, I would better propose to revert the MakeHookWithData() stuff
Sebastian changed in SDI_hook.h. I guess he just missed that this
MakeHook()/MakeStaticHook() are only allowed directly after the closing
braces after a HOOKPROTO() definition. The current scheme doesn't allow to
have two MakeHook() followed each other.

So, either we revert the stuff or we copy&paste the export hooks and make
two out of them with removing the TRUE/FALSE h_Data alteration. Perhaps
probably that would be even better than reverting sebastian's change as we
would anyway change the ExportHook sooner or later.

Opinions?

cheers,
jens
