That aside though, if the windows 32-bit dev tools support building
64-bit binaries (I have no idea if they do) then it should be as simple
as configuring with --with-target-bits=64. But so far all our
cross-compiling of this form has been on linux and only tested for
building 32-bit on a 64-bit host.
