It looks like we falsely assume the compiler understands C++11 and thus use attempt to use std::integral_constant. Could it be that the conditional in https://github.com/boostorg/python/blob/develop/include/boost/python/detail/... is wrong ?

You should probably be checking BOOST_NO_CXX11_HDR_TYPE_TRAITS there unless you have a specific reason not to do so. Yes, but I think the error is because it doesn't understand the C++11 type alias. Better to use:

typedef std::integral_constant true_; typedef std::integral_constant false_;

According to MSDN, std::integral_constant was in Visual Studio 2008, which is Visual C++ 9.

OK, thanks. I have committed https://github.com/boostorg/python/commit/b9d0d974995d2ed6a7aeed877ee4d8ab0a... and will merge to master once the change cycles through a round of tests. (I have to admit that I find it extremely daunting to navigate the online test matrix. There are so many false positives that it's hard to spot actual failures.)
