I'm using 3.4 ... but I wouldn't call 3.2 old.
I have an old (slow) machine with 3.0 on it, so I'm going to update it to the current GNUstep code from cvs, and try building and running your zillion test there.

Ok ... I had to hack the zillion code around a bit to get it to compile with gcc-3.0 (that compiler doesn't support forward declaration of protocols), but when I ran the resulting code it crashed. Looks like this is the old compiler bug of Protocol objects not being properly initialized by the compiler/runtime. I had thought that this was fixed by gcc-3.2 but it looks like that is not the case :-( Probably you need 3.3 or later.

I think it is possible to code an (ugly) hack to work around the problem into the NSDistantObjects code. I may do that after lunch.
