    1 The file <prefix>/include/kdemacros.h is apparently generated by the CMake script <prefix>/share/apps/cmake/modules/FindKDE4Internal.cmake, where the KDE build tries to establish the compiler environment.  After my kdelibs4 @4.8.2_0 install, I found that no other libraries I compiled and built with #include kdemacros.h could be linked to applications code (I have a development version of KDE Games on Apple).  The reason was that GCC visibility of library classes and symbols was not available, because kdemacros.h did not have __KDE_HAVE_GCC_VISIBILITY defined.

    3 Macports 2.0.4, XCode 4.2.1 and OSX 10.7.4 are giving me the symbolic link /usr/bin/c++ -> llvm-g++-4.2  When I force definition of __KDE_HAVE_GCC_VISIBILITY in my CMakeLists.txt, everything compiles and links OK and works fine.  So I guess llvm-g++-4.2 is a GCC-like compiler, but is not being recognised as such.
