Maybe just some #ifndef's, combined with -D's in the GNUMakefile would

gnustep-make automatically adds -DGNUSTEP on the command line when
compiling for GNUstep.

So what I do, and what I guess most people are doing, is

#ifndef GNUSTEP
 /* Apple specific code */
 /* GNUstep specific code */

You don't need any autoconf or scripting, this should always work: if you compile GNUstep code using GNUstep, GNUstep is going to be defined; if you
compile for Apple (using GNUstep or PBX), GNUstep is not going to be

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"

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