The win64.mak files included with druntime and phobos depend upon "Microsoft Visual Studio 10.0\VC" and "Microsoft SDKs\Windows\v7.0A", neither of which seems to be readily available for download from Microsoft's site anymore.

I tried changing the paths to point to VS 14.0 and Windows SDK 7.1A, but the build failed:

> // druntime win64.mak:
> src\core\stdc\errno.c(12): fatal error C1083: Cannot open include file: 'errno.h': No such file or directory
> 
> // phobos win64.mak:
> adler32.obj : fatal error LNK1107: invalid or corrupt file: cannot read at 0x517

1. How can I get the build working on my own system?
2. Isn't it about time to upgrade to a newer version of these dependencies?
