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/type_traits.hpp#L10-L11
is wrong ? (If it was set to 'true' for MSVC 10.0, and 'false' for MSVC
>= 11.0 , when it should in fact be 'true' for MSVC 11.0, too, this
might explain the error. But given that I'm not very familiar with MSVC,
this is pure speculation. I'd appreciate any help from some Windows
experts.)

Thanks,

Stefan
