Re: [eigen] 3.2.10 released!

Thank you for the feedback, it's reassuring that it still works with MSVC2010 (thanks to your efforts). Regarding gcc 4.1, I would not waste time on it. It's really too old, and it always gave poor performance with Eigen.

Thanks for the great work. I just tested the default branch with MSVC2010, gcc 4.8.4, gcc 4.4.6 and gcc 4.1.2. Only gcc 4.1.2 fails:

Eigen/src/Core/util/Meta.h:410: error: no matching function for call to Eigen::internal::scalar_constant_op<double>::operator()(long int, long int) const
Eigen/src/Core/util/Meta.h:401: error: no matching function for call to Eigen::internal::scalar_constant_op<double>::operator()(long int) const
Eigen/src/Core/util/Meta.h:392: error: no matching function for call to Eigen::internal::scalar_identity_op<double>::operator()() const

I tried to fix it, but the obvious trivial fixes didn't work. I will have to lookup how boost.mpl (or rather boost/type_traits/details/has:binary_operator.hpp) does it. At least that is my current plan. I will try to post a patch with a fix today.
