+    Use Eigen2's newer StdVector implementation if it is available.
+    
+    This should fix the build with libc++ (ie. recent versions of FreeBSD and OS
+    X at least), as Eigen2's default StdVector implementation reimplements
+    std::vector in an incompatible way.
+    
+    Defining EIGEN_USE_NEW_STDVECTOR makes Eigen >= 2.0.6 use the new
+    implementation that does not have these problems and is the default in
+    Eigen3.
