It's not going to work perfectly out of the box, especially since we are missing exception-handling support for MinGW.

If you're willing to dig into the guts of the compiler, debug issues, and write patches, that's great. I don't know if it's a day's worth of work or a month's worth of work. 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.
