As I have nearly finished with arts, and compiled kdelibs with 
-fvisibility patched gcc 3.4.2, I didn't notice any problems yet.
Some solution needed, because the current situtation breaks the compile 
process. The -fvisibility=hidden flag added, but the KDE_EXPORT macro 
not defined correctly.
What about passing a -DHAVE_HIDDEN_VISIBILITY option with the 
-fvisibility=hidden flag, this doesn't require config.h?
