Well, I'm typing this from kde3.0.3 compiled with gcc3.2 on a Debian stable 
system. It's running great, no crashes, no nothing. No artsd, though not 
because of artsd problems: I just don't want sound at work, in a remote-X 
situation, with no sound card on that workstation (or the X application 
server) =)

Yes. Better C++ support. 

It doesn't change THAT much for KDE itself. It's just plain better altogether, 
probably optimizes faster, and is supposed to be with a stable ABI.

Compilation itself is slower, and it's definately noticeable. I'd say half as 
fast, and I'd advise you to use --enable-final on everything you can (whole 
of KDE for example). 

Do the applications run faster? Not sure. They appear to, but then again, I 
went from KDE3.0.1-gcc-2.95-4 to KDE3.0.3-gcc-3.2 so part of the speedup 
might just be KDE bugfixes. (Or a lesser load on the application server, for 
that matter)

Not sure. The plan is for gcc to do most of what objprelink was doing, but I 
have no idea how far they got with that. Moreover, I seem to recall that you 
don't need to give a ./configure parameter anymore, one just installs 
objprelink and it should 'just work'. Can anyone confirm?

Whatever comes with 3.2, hopefully.

Quite true! =)

Have fun,
