The D3D11 renderer is now slightly faster than D3D9 on my Windows 8 machine (testsprite2 runs at 3400 FPS vs 3100 FPS)
This will need tweaking to fix the Windows RT build.

Fixes the version check for some functions that are only present with the MSVC 2013 CRT libraries.
I did my testing wrong and failed to see that 2012 doesn't have these functions. Microsoft implemented them in their upcoming 2013 version, though. The attached patch changes it to the check for the next version.
I also removed the HAVE_ITOA because that would require linking with oldnames.lib and it's easier to just let the SDL implementation take over.

Adds a condition so only the MSVC 2012 compiler defines the macros for the functions of its version.
Attaching a patch that adds a condition so that the HAVE_X supported by MSVC 2012 only get defined with that compiler. MSVC 2008 and 2010 will then build without any modification to the SDL source code.
Also moved HAVE_M_PI to a separate check. The Microsoft headers require _USE_MATH_DEFINES to be defined before they define the constants.
It's a long-dead platform, and we don't have any way to build for, test, or
maintain it, so there's no sense in doing acrobatics to support it.
If you need Windows CE support, use SDL 1.2. If you need Windows Phone support,
send SDL 2.0 patches for the newer Windows Mobile platform.
