No gcc-stuff anymore (cleaned via make delete-old)
>Description:
Compiling www/qt4-webkit fails with a lot of compiler errors on a most recent CURRENT box with GCC gone (CLANG only, libc++ only).

The initial error seems a commong compiler bug, while the second error (out of a bunch of errors selected as representatives) seems to be clearly a missing ext/xxx.h header vansihes from GNU GCC 4.2.
