 677     __WXOSX_OR_COCOA__ is a common define to wxOSX (Carbon or Cocoa) and wxCocoa ports under OS X.
 678
 679     DO NOT use this define in base library code.  Although wxMac has its own
 680     private base library (and thus __WXOSX_OR_COCOA__,__WXMAC__ and related defines are
 681     valid there), wxCocoa shares its library with other ports like wxGTK and wxX11.
 682
 683     To keep wx authors from screwing this up, only enable __WXOSX_OR_COCOA__ for wxCocoa when
 684     not compiling the base library.  We determine this by first checking if
 685     wxUSE_BASE is not defined.  If it is not defined, then we're not buildling
 686     the base library, and possibly not building wx at all (but actually building
 687     user code that's using wx). If it is defined then we must check to make sure
 688     it is not true.  If it is true, we're building base.
 689
 690     If you want it in the common darwin base library then use __DARWIN__.  You
 691     can use any Darwin-available libraries like CoreFoundation but please avoid
 692     using OS X libraries like Carbon or CoreServices.
