Note that cxx6.0,1,2 have many problems. When I generate the binary tar files for this compiler, I always compile the graf/src/*.cxx in debug mode. Otimized code does not work. If you do not use the precompiled libraries from the CERn web site, and recompile teh code yourself, i stronly suggest to compile the graf classes in debug mode.
