Compiling 64 bit windows is now possible using cygwin?

[KilianB]

The wiki states:

The long story is that there is no native 64bit version of cygwin which I use to compile ATLAS
https://github.com/mikiobraun/jblas/wiki/Why-There-Is-No-64bit-Support-for-Windows

As far as I can tell cygwin now offers 64 bit support for windows https://cygwin.com/install.html and
http://math-atlas.sourceforge.net/atlas_install/node55.html as well as http://www.pulpgaming.com/2017/01/building-atlas-v3-10-3-for-x86-and-x64-on-windows-10-with-visual-studio/ are talking about building atlas for 64 bit.
I am not much of a c guy and so I might be missing something, but are we now able to compile a fitting version?

Edit: #93 I see that you mentioned not having much time to look into it

I've heard that 64bit compile works now, but never found the time to dig into it. Sorry.

Hi Kilian,

yes, it might be possible now, but I also don‘t have access to a good Windows machine. Mine is pretty old and has an AMD processor. Not sure compiling ATLAS there will result in good code...

In case anyone has access & capabilities I am happy to collaborate.

Best,

Mikio

I've recently started using openblas which has an easier compile process for Windows, and I got a new machine, so let me put this in the backlog.
