Ok. I give up this futile list attempt, mainly because of the semantic 
problems that arise. A good general list ADT with type safety is hard to 
accomplish in a safe manner. My strategy was to create some sort of generic 
backend which could be wrapped with inline functions to provide type safety. 
But the polymorphism required can only be accomplished with void pointers, 
thus reference semantics is what's down the road. This may or may not work, 
but it could imply overall design changes on RSBAC, which was not the 
intended idea.

Template-like solutions using macros is a possibility, but I don't want to go 
there. 

So I hereby declare myself defeated by C's weak type system.
