Yes, you are correct and I was wrong. I just checked out the mingw-64
project and there has been a lot of activity the last couple month,
including a patch to build pthread-win32 in 64 bit mode.

I would really like to find the actual reason *why* the legal status of
the 64 bit MinGW port is murky (To my knowledge it has to do with taking
code from the MS Platform toolkit - but that is conjecture), so I guess
I will do the obvious thing and ask on the MinGW list :)

Sure, I do see your point.
Accidentally someone posted about
http://debian-interix.net/
on the sage-windows list today. It offers a gcc 4.2 toolchain and AFAIK
there is at least a patch set for ATLAS to make it work on Interix.
