Let me try to explain what I mean by saying "executable form".
Kaffe floads the necessary classes into memory when they are nedded.
They are stored in some kind of struct class and a method structure.

I would like to save these structures in a kind of include-file and 
integrate them into the executable.

Has anyone tried something like this or can you imagine something
similar ?
I do not have a filesystem, so that the classes cannot be loaded at
