It will be fairly complex, and will probably add a lot of different
constraints, I'm not sure it would really be an improvement over
winebuild. If you want a really transparent solution then it should
most likely be done directly at the linker/ld.so level.

They will still be a problem, you'll need to redo the resource
functions to deal with that. Other problems include at least ordinal
exports, separate dll namespaces, and initialization order. Then of
course you have all the binary compatibility problems with module
handles that don't point to the right structures etc.

If you really want to provide a seamless Unix source environment, you
pretty much need to give up on full binary compatibility, and do
something more like what TWIN was doing. But I don't think that's
where we want to go.
