In fact those files are there so in the future we could ease 
compatibility. 

GNUstep is not a Cocoa clone even though it tries to be compatible where 
it makes sense.  It has some useful extensions.  You may notice that the 
headers you find in GNUstepGUI are not part of AppKit on Cocoa.  Some of 
them should be considered private to GNUstep (they are needed for 
integration of the display backends or Gorm.) others are true 
extenstions.  When the need arises and someone is willing to do the 
work, you may be able to build a GNUstepGUI library or framework on top 
of Cocoa.  It would only contains the gui extensions of GNUstep but 
otherwise relies on AppKit.  This would make it easier for GNUstep based 
apps that use the extensions to run on Cocoa.

This has already been done for gnustep-base (ie. GNUstepBase) but it 
will take some work to cleanly do it for gnustep-gui.
