OK, I undestand that stuff well.  But is this macro defined in Cocoa's 
headers, too?
Otherwise, I feel the instruction above is applied to code written only 
for GNUstep,
not for code compatible with both GNUstep and Cocoa.

In addition, my question is about real incompatibility, not about any 
class/method found both in
GNUstep and Cocoa.  I seek for such a predefined macro that enables a 
conditional complication like

#if defined SOME_MACRO
   <GNUstep-proper code comes here>
#else
   <Cocoa-proper code comes here>
#endif

In other words, I seek for a macro which differentiate GNUstep headers 
and Cocoa ones,
not a macro which can be used to decide whether GNUstep's Cocoa API is 
used or not.
