  89     __WXOSX_OR_COCOA__ is a common define to wxOSX (Carbon or Cocoa) and wxCocoa ports under OS X.
  90
  91     DO NOT use this define in base library code.  Although wxMac has its own
  92     private base library (and thus __WXOSX_OR_COCOA__,__WXMAC__ and related defines are
  93     valid there), wxCocoa shares its library with other ports like wxGTK and wxX11.
  94
  95     To keep wx authors from screwing this up, only enable __WXOSX_OR_COCOA__ for wxCocoa when
  96     not compiling the base library.  We determine this by first checking if
  97     wxUSE_BASE is not defined.  If it is not defined, then we're not buildling
  98     the base library, and possibly not building wx at all (but actually building
  99     user code that's using wx). If it is defined then we must check to make sure
 100     it is not true.  If it is true, we're building base.
 101
 102     If you want it in the common darwin base library then use __DARWIN__.  You
 103     can use any Darwin-available libraries like CoreFoundation but please avoid
 104     using OS X libraries like Carbon or CoreServices.
