Yes, 4.2.1 is the latest we can use.
Also, I have no idea what version of Clang Michael is using on OSX. That
tag means nothing to me; for all I know that really could be back in Clang
2.1 days which makes this exercise pointless. We need to be comparing at a
minimum the very latest Clang to GCC 4.2.1. Further benchmarks against the
latest GCC is welcome, but we should care more about not having a huge
performance regression in comparison to what GCC 4.2.1 already provides us.
