The pattern used in xmmintrin.h is to put these typedefs inside the function that uses them, e.g.:

static inline __m128 __attribute__((__always_inline__, __nodebug__))
_mm_andnot_ps(__m128 a, __m128 b)
{
  typedef int __v4si __attribute__((__vector_size__(16)));
  return (__m128)(~(__v4si)a & (__v4si)b);
}
