now wine is undergoing a big work on 64bit and i don't think that it
will take much to have it working. it has
configure options for 64bit builds but they sustain that 64bit code
need 64bit windows apps, that aren't
around. maybe you might try to compile it with -m64 instead of -m32,
but i don't know if it will work and even
if it works you'll then need native windows 64bit apps.
the other choice is to have a no-multilib 64bit system and build
another chroot for 32bit, in which to install only
the needed 32bit apps with only needed use flags. if you just use wine
you could pick a 32bit tar release from
funtoo, and build in that chroot only wine with stripped flags. you
shouldn't need so many packages for this.
then just adjust your server to the right output (usually running on
0:0) will do and will start your 32bit app in the
same screen as the one you're using (since usually xorg uses 0:0).
