[SciPy-Dev] SSE instruction in arpack file - f2py issue?

[Ralf Gommers]

When checking the 0.8.0b1 superpacks I found a single file with SSE
instructions, sparse/linalg/eigen/arpack/_arpack.pyd. The only thing
possible explanation I found is that f2py can add SSE instructions by
default, as claimed here:
http://thread.gmane.org/gmane.comp.python.f2py.user/712/focus=6882. Is this
correct? Anyone have any other suggestions on where to look?

Thanks,
Ralf
