I tried using the info at
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccelng
/htm/msmod_18.asp

ie typedef struct __declspec(align(16))
{
    float f[4];
} __m128;

buut the MS compiler to which I have access doesn't support
__declspec(align())

Does VC7 not have __m128 intrinsic type?
