Not done it - but should be doable - normal MS approach to L14N. From the links near the bottom, it looks like if you want or need a DllMain, you have to write and build it, as would be expected, so just don't do that! See what mintty and setup do with their resources in their build processes: See man dlltool(1), windres(1), -- Take care.
