I'd like to use numpy.distutils.cpuinfo to check if I can enable some
flags during compilation of Fortran code. The issue I face is that an
Opteron 254 does not have SSE3. So says /proc/cpuinfo. But in fact
_has_sse3() returns True on this paltform. But not _has_ssse3(). What
are the differences between both values ?

On a side note, is testing for sse4 in the pipeline ?
