Of course I want to support them.. so nice to have stuff run on my 
iBook and PowerBook !

I think this is finer:

#if !defined (GNUSTEP) &&  (MAC_OS_X_VERSION_MAX_ALLOWED <= 
MAC_OS_X_VERSION_10_4)
#define sel_isEqual(selector1, selector2) (selector1 ==  selector2)
#endif

So it is just there for "old" MacOS and GNUstep and more modern MacOS 
are fine.
I wonder if the limit is 10.4 or 10.5, on 10.6 sel_isEqual works.

Thanks and have fun playing with Graphos :)
