Re: [eigen] eigen3 migration

[Benjamin Schindler <bschindler@xxxxxxxxxxx>]

Okay, after deleting millions of lines of code, I managed to reduce it
to this:

#define Success		   0	/* everything's okay */
#include <eigen3/Eigen/Core>

And this define comes from X.h, so it's rather standard

Cheers
Benjamin
