This winterbreak i looked into this again, too. I was quite suprised that i had no problems with socket credentials, but it might still be a problem in other hurd distros.

I recently sent a patch for this and failed, problem is that you can't allocate memory inside an APC callback.
I think we should address this first before the other issues.

The interesting part of these patches were made by Andrew Nguyen some years ago, i already contacted him some days ago to ask how he wants to proceed with this, no response yet.

These are winelib apps and a bad indicator for functionality. I tried PowerPointViewer here for this reason and it installs and runs.
