The history here are PR 3130, 3131 and 3145, with 3145 not being completely
resolved yet. The bad thing is that compared to 3.0 we already have a
regression with 3.0.1, see
<http://gcc.gnu.org/ml/gcc-patches/2001-06/msg01636.html>.
Besides that I was able to compile a working (including arts)
qt-2.3.1/kde-2.1.1 setup (this means the
kdelibs/kdebase/kdenetwork/kdeutils packages) on powerpc-linux-gnu with
gcc-3.0, and a working kde-2.2beta1 (kdelibs/kdebase so far) with current
gcc-3.0.1 (with Jasons last patch to class.c reverted to get arts to link).
