Derivative works of Emily Short’s Bronze are permitted. @Marnix, the creator of the development system that was the topic of that thread, took advantage of this to make an XVAN port of Bronze.
- Archive of Bronze’s web page, including source code
- @Shin 's port of Bronze to I7 9.3/6M62 would be more convenient if you wanted to be able to compile it on a modern system
While looking up links for this, I found Emily Short answering this very question on her blog in 2018: IF Candidates for porting.
