Build failure using clang5 and clang6 on Windows

[macdew]

Our project works fine with Visual Studio cl.exe, but when I use the LLVM clang-for-windows compiler, I get the following error:

  In file included from msgpack\2.1.5\include\msgpack.hpp:18:

          o.pack(std::get<0>(v));

Clang on linux and Mac work fine, I think this may be a combination of clang with the microsoft runtime/headers? The compiler shows a bunch of failed matches, including in C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include\tuple

This happens in Visual Studio 2015 (and Visual Studio 2017) when you install the clang compiler from llvm.org, then compile using the LLVM-vs2014 toolset.
