GCObject? What's this? How to port?

[Philip Mötteli]

Hi


I made a first attempt to port GDL2 to MOSX. Apart from some cycled 
imports I have especially one problem: What are those GC objects? 
"Garbage Collectable", I think. But how should that map to the 
'Retain/Release' strategy of Cocoa?


Thanks for any pointer!
Phil
