Greetings Jacek,
Been following your user32 -> win32u work for a while now. Glad to see it done(?).
What's the goal behind this follow-up work?
AFAICT the aim is ensure no unix code depends on code which is (should be) built only as PE. Thus ultimately, wine will ship only the .dll files, without the accompanying .a archives. Seems like that will lead to some duplication, although if it's getting too much, guess one and move it under lib/foobar.
Does that sound about right, is there more to it?
Thanks Emil
