And if you use the GNUstep make package on OS X (and you know, Helge 
insists on that being ported to OS X every once in a while ;-) you're 
stuck! :-) Because you also need to identify the runtime, because 
GNUstep doesn't always mean GNU runtime.

I always define the following in every GNUmakefile of our packages:

ifeq "$(OBJC_RUNTIME_LIB)" "gnu"
ADDITIONAL_OBJCFLAGS += -DGNU_RUNTIME
endif

It would be nice and helpful if the GNUstep make package would define 
this automatically.

Cheers,
