Mostly C++11 support.

The main reason is that Apple has removed all gcc tools from recent Xcode, so although the SL build itself is fine and stable, you can't easily build new packages from sources on Mavericks+ using the SL build. There are also a few work-arounds for issues with Mavericks+ (AppNap, ...) that cannot be used in the SL build since the API didn't exist there.
