If I'm not mistaken, llvm-gcc is based on GCC 4.2. MinGW-w64 only started
existing around GCC 4.3, with a working implementation at GCC 4.4 (with lots
of local patches required) and a vanilla (unpatched) implementation at GCC
4.5+. I think you're currently out of luck here. Why not try Clang itself
(if you don't need fortran or any other non-C family language of course)?
