Hi Kohei,

Sorry it is without --std=c++11 that every thing is fine.

The boost code manages to solve not having std::forward when compiled without the std=c++11 flag.

With --std=c++11 I get the compiler errors about missing std::forward.

I have tried all the boost macros that pertain to library features with no success. I did at the option BOOST_NO_CXX11_CONSTEXPR and this doesn't work either. The compiler is the full clang 3.4 and does support c++11 features such as constexpr. It is the library that is old.

std::printf("GLIBCXX: %d\n",__GLIBCXX__);

produces

GLIBCXX: 20070514

Below is the full source with all the macros I have on:
