 717     __WXOSX_OR_COCOA__ is a common define to wxOSX (Carbon or Cocoa) and wxCocoa ports under OS X.

 720     private base library (and thus __WXOSX_OR_COCOA__,__WXMAC__ and related defines are
 721     valid there), wxCocoa shares its library with other ports like wxGTK and wxX11.
 722
 723     To keep wx authors from screwing this up, only enable __WXOSX_OR_COCOA__ for wxCocoa when
 724     not compiling the base library.  We determine this by first checking if
 725     wxUSE_BASE is not defined.  If it is not defined, then we're not buildling
 726     the base library, and possibly not building wx at all (but actually building
 727     user code that's using wx). If it is defined then we must check to make sure
 728     it is not true.  If it is true, we're building base.
 729
 730     If you want it in the common darwin base library then use __DARWIN__.  You
 731     can use any Darwin-available libraries like CoreFoundation but please avoid
