Got ya! :-)

I recently removed exactly that define from objc-gnu2next.h because the 
mapping doesn't hold.  GNU ObjC runtime's class_get_class_method expects 
a meta class where Apple's class_getClassMethod expects a class.  You 
could map it to:
#define class_getClassMethod (aClass, aSelector) \
   ( class_get_class_method ((aClass->isa), (aSelector)) )
but the reverse couldn't be mapped,
