These are now just Warnings. My thought was that maybe the new version
of cython raises a warning when it encounters the binary size mismatch
instead of the exception that it raised before.
(I think "from scipy import stats" or "from scipy import vonmises" (in
a fresh interpreter session) should show whether the cython problem is
solved.)
Just a guess,
(I will test tomorrow on XP)
