I seem to remember writing a post recently that described how to test for 
libobjc2 and for the various optional features compiled with it.  The simplest 
thing to do is just #include <objc/runtime.h> and then see if 
__GNUSTEP_RUNTIME__ is defined.  If it is, skip all of the other checks and 
assume a modern runtime.  You can also use objc_has_capability()  to test for 
optional features, but since GNUstep doesn't currently use any of the optional 
features of libobjc2 this isn't a problem.
