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

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