/* the ugly part below: many versions of gcc used to be completely buggy with respect to some intrinsics
The movehl_ps is fixed in mingw 3.4.5, but I found out that all the _mm_cmp* intrinsics were completely
broken on my mingw gcc 3.4.5 ...
Note that the bug on _mm_cmp* does occur only at -O0 optimization level
