  84     __WXOSX_OR_COCOA__ is a common define to wxOSX (Carbon or Cocoa) and wxCocoa ports under OS X.
  85
  86     DO NOT use this define in base library code.  Although wxMac has its own
  87     private base library (and thus __WXOSX_OR_COCOA__,__WXMAC__ and related defines are
  88     valid there), wxCocoa shares its library with other ports like wxGTK and wxX11.
  89
  90     To keep wx authors from screwing this up, only enable __WXOSX_OR_COCOA__ for wxCocoa when
  91     not compiling the base library.  We determine this by first checking if
  92     wxUSE_BASE is not defined.  If it is not defined, then we're not buildling
  93     the base library, and possibly not building wx at all (but actually building
  94     user code that's using wx). If it is defined then we must check to make sure
  95     it is not true.  If it is true, we're building base.
  96
  97     If you want it in the common darwin base library then use __DARWIN__.  You
  98     can use any Darwin-available libraries like CoreFoundation but please avoid
  99     using OS X libraries like Carbon or CoreServices.
