That's basically the configuration I'm using thus far too, so if there are
problems with it, I'd like to know about them in case they're problems I'm
going to run into in the near future! Why is that configuration not working
for you? What sort of errors are you getting?

I'm using Visual C++ 2015 and clang 3.7.0, with everything set to 64-bit,
is that the same as you have?
