I've never heard of it not using it. Even if you run "clang -stdlib=libc++" on 10.7 with a super ancient compiler, you get (some of) C++11 by default. The only exception is this one: - https://trac.macports.org/ticket/53634 but that one has nothing to do with the stock compiler. > Lots more head-scratching along these lines… Any pointers would be > appreciated!
