A lot of the lowest level stuff is currently missing. If you don't
mind x64 assembly it's not impossible to do. We would need support
from gcc for the windows calling convention, and making it possible to
mix linux calling convention with windows calling convention. If you
are up to it just make it ignore the error for now, even if it causes
errors. A proof of concept "Hello, world!" would be a great
accomplishment at this point.
