Build failure on Windows 10 using vc12

Hi
After failing to build on OSX, I gave win10 a chance, however this results in:

Done Building Project "D:\d\fips-build\oryol\win64-vstudio-debug\fips-zlib_zlib\zlib.vcxproj" (default targets).

Done Building Project "D:\d\fips-build\oryol\win64-vstudio-debug\ALL_BUILD.vcxproj" (default targets) -- FAILED.


Build FAILED.

Are you living near a nuclear power plant or something? ;)

I think vc12 is Visual Studio 2013? This only has very limited C++11 support, which may explain the problems (see here: https://msdn.microsoft.com/en-us/library/hh567368.aspx). VS 2015 should work.

PS: hmm but in the Readme I'm mentioning VS 2013, so I guess it worked at some point. But since a few years I've only been testing with VS 2015 and 2017.

PPS: another reason could be missing VS 2013 updates, there have been 5 service packs, and if I remember right C++11 support improved a lot during that time.
