I can take care of that and I'll post a speculative patch for it as I
don't have a gcc 4.6 at hand right now to test it my self.

ACK.

Before I can apply this patch we need to solve an issue with email
address. You used a RedHat one for this patch, but you are listed with
a Gnome one in the AUTHORS. This makes the syntax-check unhappy. We
can solve this by adding your RedHat address as an alias to the Gnome
on to the .mailmap file or use your RedHat as the mail one in the
AUTHORS files and add and alias the other way around to the .mailmap
file.

What way do you prefer?

Matthias
