In principle, yes. In practice right now, no. Stephen Kitt has looked
into this and gave a comprehensive talk at this year's mini-debconf
(But I can't find a URL as I'm not sure that Sylvestre has actually
uploaded them anywhere). I think this pdf is the slides though:
It has the potential to be exceedingly slick and remove a whole load

Yes, but it needs some work. I'm sure Stephen would love some help :-)
I don't know if he's made any progress since feb.
The trickiest part is that, having demonstrated that this works, we
would have to change the definition of 'architecture independent' a
little to include 'posix/non-posix' which mostly means moving a lot of
libc stuff from arch-independent locations to arch-dependent
locations, and that might be a hard sell in Debian. It _should_ only
affect libc packaging, but work needs to be done to demonstrate
that. Everything else is straightforward, and indeed a simplification of the current state for any package that produces win32/64 libs.
