Which imply that there is likely a compilation issue on your side, as 
the patch is disabling SSE2/3 versions of hadamard_ac.

I tested on my side, and to me hadamard_slowmod4 patch and updated msvc 
workspace are all that are necessary to have trunk version working on an 
SSE2 processor when compiling with msvc.
