  53     __WXOSX__ is a common define to wxMac (Carbon) and wxCocoa ports under OS X.
  54
  55     DO NOT use this define in base library code.  Although wxMac has its own
  56     private base library (and thus __WXOSX__,__WXMAC__ and related defines are
  57     valid there), wxCocoa shares its library with other ports like wxGTK and wxX11.
  58
  59     To keep wx authors from screwing this up, only enable __WXOSX__ for wxCocoa when
  60     not compiling the base library.  We determine this by first checking if
  61     wxUSE_BASE is not defined.  If it is not defined, then we're not buildling
  62     the base library, and possibly not building wx at all (but actually building
  63     user code that's using wx). If it is defined then we must check to make sure
  64     it is not true.  If it is true, we're building base.
  65
  66     If you want it in the common darwin base library then use __DARWIN__.  You
  67     can use any Darwin-available libraries like CoreFoundation but please avoid
  68     using OS X libraries like Carbon or CoreServices.
