(This code, which is being removed, used "," to avoid having to introduce
braces. There's another instance of this pattern a bit above.)

(Adding a brace here.)

"is now forced" sounds more like it describes this change/commit, rather
than this piece of code. Maybe this final sentence can be scrapped
entirely, since the forcing/translating/mapping is obvious from the code
anyway? The remainder of the comment goes into *why* and looks more
useful. Just my 2 cents.

Now there's no need to avoid introducing braces, so maybe split this
into two lines for a lower huh-factor?

  errno = err_win_to_posix(err);
  return -1;
