Compiling SDL 1.3 with mingw

So I’ve been trying to compile the CVS version of SDL 1.3 with codeblocks/mingw, It was saying that the precompiler commands were erroring so I deleted those, and now it is giving me lots of this error message
error: can’t convert between vector values of different size
in these files
emmintrin.h xmmintrin.h mmintrin.h
when I compile SDL.
Any help would be greatly appreciated
