Hm, good point, I don't know why I read putting .wine stuff into
vendor instead of the opposite.

Anyway, the way to use the binaries is to put them in some known
location, e.g. C:\local ($WINEPREFIX/drive_c/local for wine), and copy
the nosse/sse2/sse3 directories in there. For example:

C:\local\lib\yop\nosse
C:\local\lib\yop\sse2
...

This is then referred through env by the pavement script (see
https://github.com/numpy/numpy/blob/master/pavement.py#L143). Renaming
yop to atlas would be a good idea, don't know why I let that
non-descriptive name in there.

Manually, you can just do something like "ATLAS=C:\local\lib\yop\sse2
python setup.py build", but being careful about how env variables are
passed between shell and wine (don't remember the details). Note that
the nosse is not ATLAS, but straight netlib libs, which is why in that
case you need to use BLAS=... LAPACK=...

I would strongly suggest not to use openblas for this release, because
of all the issues related to CPU tuning. We could certainly update a
bit what we have in there, but building windows binaries is big enough
of a pain, that you don't want to do everything at once I think,
especially testing/building blas on windows is very time consuming.
