Nothing changed yet, we have to get it past Alexandre first. I'm not
really keen on how huge the patch has become, but I guess that's
portability for you :)

If the patch goes in, you will be able to compiled a Winelib app and run
it like so:


and put it in the path etc. The "wine" thing will be no
longer required, though it will still work.

No sorry. gdb has a lot of problems debugging even UNIX apps these
days :( I agree that it is awkward and we should do some work to make
gdb operational with Wine again at some point (probably means fixing gdb
bugs unfortunately).

No, this is unrelated to that work I'm afraid. You still need to borg
your program if it wants to use Wine.

Some good work was done in the winelib-in-midflight area, and I think
it's fair to say that we now know how it should be done. But there's a
big difference between having a patch that works, and having it
supported and in CVS.
