If GNUstep is going to such a direction that it adopts C APIs
that are supported by both Mac OS X and iOS (e.g., Core
Foundation, Core Graphics, Core Text and Image I/O), then many
parts of the code of the Mac port will become usable also in
GNUstep.  As a result of transition to 64-bit and Cocoa GUI, many
uses of C APIs in the Mac port already fall into this category.

Of course, there will remain some Mac OS X-specific parts, and as
it is shown by the current NS port status, practice will not
always work as in theory.
