--- Comment #10 from Tim x@vaults.ca --- I did the above tests on two up-to-date Arch Linux systems many times, and never did manage to get it to work. However, I recently just had to install Arch on a new box and decided to retry this, and it worked!
It doesn't seem likely that I was missing a 32 bit host package on the old installs, which is somehow magically present in the new install. I wonder if there is some old wine configuration that persists (independent of instances) that could mess something up which the default configuration doesn't contain? I don't know, just a wild guess.
Anyhow, I just wanted to add a note here in case anyone looks, that I did get it to work at long last -- with a clean install of the entire operating system!
And thanks to Anastasius Focht for looking into it all those months ago.
