Compile break when building with Microsoft STL using a different compiler then msvc

[ChristophStrehle]

When building with the Microsoft STL and a different compiler then the msvc I get the following compile break in std::vector:

1>..\MSVC\14.43.34808\include\vector(656,38): error : no matching conversion for static_cast from '_Alty' (aka 'AllocatorWithCleanup<unsigned char, false>') to '_Rebind_alloc_t<_Alty, _Container_proxy>' (aka 'AllocatorWithCleanup<std::_Container_proxy, false>')

This can be reproduced when building a simple program using cryptopp and clang-cl.
