The "Microsoft Visual C++ Compiler for Python" is essentially the Visual
Studio 2008 compiler. PyOpenCL >=2015.2 uses the C++11 standard, which
this compiler does not support.
The options to build PyOpenCL for Python 2.7 on Windows are to 1)
downgrade to PyOpenCL 2015.1 or 2) use mingwpy compilers
<https://anaconda.org/carlkl/mingwpy>. Unfortunately the 64 bit build of
PyOpenCL 2015.2.x is not stable ATM.
According to [1] Visual Studio 2015 should be able to build PyOpenCL for
Python 3.5, but that will require more changes, e.g. on the variadic macros.

I've added an #include to perhaps help fix this in 5fcc15c. Let me know
if that makes things better.

It would be great if we'll be able to build pyopencl using "Microsoft Visual C++
Compiler for Python".
