Well - we'll release our 12.04 based rollout this year (I know we're
late ;-) and it'll be at least supported for the next 2-3 years. This
change means we won't be able to do any LO updates after 4.3, not even
thinking of building a LO version for our old 10.04 based release, which
we'll support at least for another year.

Current master still builds on 12.04 (except for collada), so it seems
all used C++11 features are also supported by gcc 4.6. There is a
unsupported gcc-4.7 in universe (4.7.0-0ubuntu4) with a newer version
(4.7.2-0ubuntu3) in precise-updates,

Like Michael Stahl, I would be happy to see an update to CentOS 6 (gcc
4.4) to get KDE4 support in the TDF packages, but an update to gcc 4.7
would probably be a lot of trouble for us.

Just my 2 cent
