which compilers do we want to support with KDE 4 ?

The ABI makes little practical difference for us at the source edge.
Nor for anyone using packages for their distro.  What is more important in 
terms of dealing with gcc < 3.4 is that it has a different C++ /parser/, 
which may mean some troubles with templates. But it's quite possible that 
it's workable --- we don't rely on templates that heavily.
