I have self compiled mingw-w64 toolchains for x64 and x86, and tested it on both.
Same for Linux x64 and x86 (The latter only compiled, not tested).

Just checked and Michael's problem comes from using Yasm 1.1.0 or older. I tested 
with 1.2.0 only so didn't notice anything.
Will try to fix it and send a new patch.
