After reading Bug #48 on github, I tried to build the 64 bit version 
from git (commit #4983507) on Windows 10 so that I could compare it with 
the official 3.7.0.0 release. Unfortunately, it refuses to build with 
Visual Studio 2015 Community Edition.

I followed the compile instructions in /windows/readme.html to the 
letter. In the same directory as readme.html, the file readme.txt states,

> The Visual Studio 2010 projects should also build fine in Visual Studio 2015
> after automatic conversion, as has been tested with the Visual Studio 2015
> Community edition.

That is NOT the case. While the conversion process did complete 
successfully, actually trying to build POV-Ray failed. There were MANY 
warnings, but the errors that stopped the build were as follows:
