Thanks for feedback @julliard and apologies for the missed authorship.
I believe the patch was Matijn Woudt (https://list.winehq.org/pipermail/wine-devel/2009-June/076173.html)
It seems this issue isn't as low hanging as I thought.
The latest messages from 2017 in Bugzilla indicated that the patch wasn't being applied properly so I thought it was a simple fix. I tested that the original error was resolved by the patch but it seems there are other issues to handle regardless of the original error being resolved.
