One solution is for 23.2 to provide an ns-compat.el library containing 
wrapper functions mapping the incompatible features
to their platform-independent replacements and emitting warnings to 
inform the user that they should change to use the platform-independent 
equivalents. Then in 23.3 or 24.1 we could remove this library from 
Emacs and require users to get it from elsewhere if they still want to 
use the incompatible features.
