Thanks ... I fixed that ... though it's clearly harmless normally, as  
the macro is defined to the same thing twice and the compiler doesn't  
even warn when a macro is being defined to the same value twice.  If  
you are encountering compiler warnings/errors then I guess you must be  
redefining GSIArray yourself, which you probably shouldn't be doing.   
Maybe you want to look into using the new NSPointerArray class instead?
Obviously NSPointerArray is new, relatively untested code, but it's  
MacOS-X/Cocoa compatible.
