To be more accurate - you should define the macros when you are building on a
MacOS/OPENSTEP system.  Otherwise your code loses the possibility of working
as efficiently with garbage collection under GNUstep.

Of course, if you are sure you will never want to use garbage collection
and/or you don't care about best possible performance, then using the retain
counting methods directly is fine.
