C++11 is orthogonal.  It's the toolchain update that's the issue I'm
worried about.  We have this problem any time we need an upgrade, which
we will in the future to fully support C++11.

No it is not because we don't yet know which specific versions of
toolchains we're going to use.  In our case we need to know the exact
point release of gcc recommended for LLVM.  4.7.x is too vague.  We want
to make sure we're using the same compiler as the rest of the LLVM
community.

The clock has wait to start once we know specific versions.
