Subject: Re: GPU support under Windows
Hello!
Thank you, if you had the time to do this we could test 7970 on Windows and
on Ubuntu (on bull@...nwall) and see the differences.
Unfortunately when I got john to build from cygwin I didn't note which
packages I needed to install, but if you want I could start from scratch
and make a list for you.
Thanks,
Daniel
