I think they meant http://www.ishani.org/web/articles/code/clangvsx/.

It's simply a plugin for Visual Studio, no more. If you want the same 
thing with Boost, simply configure a Makefile project in VS and have 
it invoke b2 toolset=clang. clang still cannot fully grok the STL 
shipped with Visual Studio and therefore uses Mingw's libstdc++ STL, 
though I should imagine the Dinkumware in VS2013 is probably the 
least customised STL Visual Studio has shipped in many years.

If you are happy to use clang as you would mingw, I've found it 
pretty good on Windows. Forget about substituting MSVC with clang 
though, they're not equivalent.

If you want a modern C++ 11 compiler on Windows, VS2013 Express is 
very good and free. I've been pleasantly surprised at its optimiser 
too, I'm seeing a nice speed bump of 15-20% when compiling C++ 11 
over VS2012, some of which is STL improvements, some is improved C++ 
11 rvalue reference support.
