Now, to be clear, what nice things would gcc-4.5 bring to our users?
There is a complete list here [0], but those ones are, in my opinion,
very nice:
  - The new link time optimiser.
  - Improved C++0x support.
  - Plugins support.

My understanding is that lto in 4.5 is not quite there yet.  Not that
I've tried it or anything.

I don't share your understanding. I tried it for some builds.

Maybe it works on small things, but I heard it doesn't work very well
for stuff like mozilla. 4.6 is supposed to get better.

I'm certainly concerned about issues such as #593876 where the
stricter linking breaks existing code.  I'm not sure about the
rationale for this extra strictness, but it does cause
unwanted breakage by breaking existing assumptions about
indirect linking.

thanks for catching this. yes, this can be reverted. I intend to make this the default for squeeze+1. Bug report are filed for these failures, see
