llvm and clang are not a Windows-based tool suite. They are independent projects that implement a virtual machine environment and compiler infrastructure and a frontend to that system. Had you followed either of my links you would have noticed that.
As an aside, if you just want to compile on the command line (DOS shell) you can still use the Microsoft compiler without using the IDE (Visual Studio).
Token plug for ported GNU compilers.
Get the MinGW/MSYS if you're using Windows, but want to run on the command line. http://sourceforge.net/projects/mingw/files/
Grab the link near the upper middle that says "Looking for the latest version?"
