I think that all these things should be possible to fix so that the
binary is acceptable
for the official NumPy binary.

How exactly do you build the binaries? I wasn't able to find the info at:

http://www.lfd.uci.edu/~gohlke/pythonlibs/

Do you have some scripts to do that? Do you use PowerShell? Or you do
it by hand by mouse and clicks in Visual Studio somehow? If I can
figure out how to do these builds, I'll be happy to figure out how to
automate it and then we can try to figure out a solution that works
for NumPy.
