I took a look btw and figured out why this is - for __v4si it's usually defined in emmintrin.h and not xmmintrin.h so to stop it from being defined earlier it's defined in each function.

Given that emmintrin.h just #includes xmmintrin.h I'm just going to hoist the definition in xmmintrin.h and remove it from emmintrin.h.
