Why not write a script  that would add #ifndef/#define/#endif into the
headers  from Apple?  (Well,  this would  not work  if some  source is
#including  twice  the  same  header  for some  reason,  like  some  C
programmers like to do. Perhaps that's  why they don't want to go back
to  #include at  Apple's,  otherwise it  would  be quite  easy to  sed
's/#import/#include/g' everywhere).


Otherwise, my first idea would  be to avoid using directly the headers
from Apple, but use some "compatibility" headers.

----------------(compatibility/Foundation/Foundation.h)-----------------
#ifndef compatibility_Foundation_Foundation_h
#define compatibility_Foundation_Foundation_h
#import </System/Library/Frameworks/Foundation.framework/Headers/Foundation.h>
#endif
------------------------------------------------------------------------

And  use -I$(somewhere)/compatibility  before  the foundation  include
that would then be shadowed.

Same for AppKit.
