 686     __WXOSX_OR_COCOA__ is a common define to wxOSX (Carbon or Cocoa) and wxCocoa ports under OS X.
 687
 688     DO NOT use this define in base library code.  Although wxMac has its own
 689     private base library (and thus __WXOSX_OR_COCOA__,__WXMAC__ and related defines are
 690     valid there), wxCocoa shares its library with other ports like wxGTK and wxX11.
 691
 692     To keep wx authors from screwing this up, only enable __WXOSX_OR_COCOA__ for wxCocoa when
 693     not compiling the base library.  We determine this by first checking if
 694     wxUSE_BASE is not defined.  If it is not defined, then we're not buildling
 695     the base library, and possibly not building wx at all (but actually building
 696     user code that's using wx). If it is defined then we must check to make sure
 697     it is not true.  If it is true, we're building base.
 698
 699     If you want it in the common darwin base library then use __DARWIN__.  You
 700     can use any Darwin-available libraries like CoreFoundation but please avoid
 701     using OS X libraries like Carbon or CoreServices.
