It does work, basically. AFAIK there are two problems with regard to KDE: 

1) The arts multiple inheritance bug. I was told this is fixed in
   gcc HEAD and that a separate patch will be provided with the next
   stable gcc release (3.0.3)

2) c++/3993 : rtti is broken when playing with dlopen. The rtti
   implementation relies on there being only one single instance of
   type_info objects (hence it can implement the == and before
   methods of type_info using address comparison) , which is accomplished 
   using weak symbols.  This is broken for some reason (ld bug?) , and it 
   hits us in a few places, like when using Blackie's regular expression 
   editor (results in failing assertions in khtml, klipper, kate,
   etc.) . (the workaround I locally use is to disable those quick rtti 
   methods and go back to the slower ones doing string comparison)
