After transferring to GitHub I cloned the project locally and tried building it; I was able to compile "Demo 8" which is a minor bugfix from the generally-available "Demo 7" previously released on my website.
Maybe one day I'll figure out how to write a BSP tree builder and find a fix for "things" (scaling sprites) that get clipped incorrectly when straddling the boundaries between sectors, but for now at least the code is no longer just mouldering away on my hard disk drive.
