Re: [eigen] How do you link multiple versions (e.g. AVX vs SSE) of the same Eigen code?

I would expect EigenAVX::Vector4d to have an alignment of 32, and only 16 
for EigenSSE::Vector4d (I did not check), which would mean they really are 
different types and you cannot pass the second one to a function expecting 
the first. So I am not sure how you intend to "pass around Eigen objects".
