But if you just want to use the compiler, I suggest using one of the better-supported platforms and hoping that someone else is going to do the work to make Clang viable on MinGW.

OK, it sounds like waiting for some future version of clang on Windows 
with MingW is best. Good luck in making that happen. I will be a great 
boon for Windows programmers to be able to use clang under Windows and 
not just under Linux.
