I/O of custom objects in CINT?

Hello!

I've tried for some time now to create objects in CINT which can be put in
TTrees, but it didn't work out. Is there some general limitation on doing
that? Do strameable objects have to be compiled?

I derived my objects from TObject, used ClassDef and ClassImp macros
(copied from Rtypes.h because of the #include problem) and Streamer
methods created by rootcint.

If I load my files with ".L" I can use the classes and see the
descriptions with ".class". But if I add a branch to a tree with:
	myTree->Branch("mybranch", "TmyClass", &gMyClass, 320000, 0); 
then it is not visible (branch name is empty) with TTree::Print and
TTree::Write causes a segfault. 

The same works fine with ROOTs compiled classes.

I can give more details if needed. (System used: 1.03/03 on Linux)

Thanks
	Robert
