Comment (by boost@…):

 I'm hesitant to reopen because I'm relatively new to boost, but I believe
 this is still a big issue, and will become even more annoying in the
 future if nothing is done. It is frustrating that it is such a hurdle to
 use modern features of the most important C++ library with a modern mature
 wide spread C++ compiler.

 Bumping `__GNUC_MINOR__` has been discussed and discarded by clang-dev
 http://lists.cs.uiuc.edu/pipermail/cfe-dev/2012-May/021510.html


 So what about an additional check using `__clang_major__` and
 `__clang_minor__`? This seems only consistent if you choose (for good
 reason) not to use `__GLIBCXX__`. Blaming this to be a bug in clang
 doesn't really help anyone either.

 P.S.:
 Even Jonathan Wakely advises against using `__GXX_EXPERIMENTAL_CXX0X__`
