--- Comment #6 from Martin Storsjö martin@martin.st --- (In reply to Erich E. Hoover from comment #5)
When you get a chance to retest, these issues should be fixed by staging commit 750044c08c49c7a117fcc911506a198969379144.
Thanks! This does seem to work correctly now. And with that in place, the vast majority of the libc++ std::filesystem tests now run correctly in Wine. There's one or a few issues left though, but the overall status seems to be that almost everything works as it should, at least the aspects that the std::filesystem tests look at (which might not be the whole picture).
