BOOST_NO_CXX11_AUTO_DECLARATIONS says that the compiler does not support 
automatic variable type deduction:

   auto x = 10;

You're using a template alias. The BOOST_NO_CXX11_TEMPLATE_ALIASES macro 
shows that the compiler lacks support for it, and it is defined for MSVC 
versions older than 12.

Boost.Config macros for C++11 features are described here:

Probably because the tests had not cycled by then?
