 Replying to [comment:17 akim.demaille@…]:
 > FWIW, I can see a significant difference bw the Ubuntu I have at hand,
 and the MacPorts: on the Ubuntu, clang used in C++11 mode does support
 C++11 with stdlibc++ (the one from GCC).  On Mountain Lion, when I use
 clang++ -std=c+11, it seems to use a pre-C++11 installation of libstdc++,
 so it does not support C++11.  So I have to pass -stdlib=libc++, which in
 turn breaks everything, since that's not the "system" C++ library.

 I assume Apple's libstdc++ is based on the one used in GCC 4.2.1, since
 that's the last version of GCC before the switch to GPLv3 which Apple
 appears to have decided as a company not to look at.

 > Can't MacPorts' deployments of clang be fixed so that they use the
 MacPorts' libstdc++?

 Please join the discussion on the mailing list that I mentioned above.
 However, we are unlikely to use libstdc++ on Mavericks even if it were
 possible; we are not here to second-guess Apple's decisions. What we are
 however discussing is whether we can switch Lion and Mountain Lion to
 libc++.
