Could you start by documenting, say on Trac or GitHub Wiki, what needs to be done? As it stands, I'm not even clear 
which of zillion mingw flavours to install.

- Why do you need clang in PATH? Is the compiler not able to find other component relative to itself?

- If clang needs mingw, it seems reasonable to document that mingw must be in PATH, and that the user must add such
   settings on Windows?

- If one has mingw with both 32 and 64 bit support, can one use it with clang, with -m32 and -m64 options both working?
   (If not, that seems like a huge bug in clang)
