Re: [eigen] Sparse Matrices, CHOLMOD & Windows

Could you try with the devel branch. I've just commit a minor change which hopefully fix the issue. If that still does not work then one solution is to move the implementation to the class declaration.

A @utoronto.ca address? Nice, i'm at the math dept :) We should meet
if you have a nontrivial interest in eigen.

As for your question, sorry i dont have MSVC to test, I hope someone
else can be more useful. It looks like it's just a matter of making
trivial adjustments to make MSVC happy.
