this should be reported upstream with a patch. There are forks which are still maintained and who likely will merge it.

I'm working on several bugs for this package, including this one.

The list of forks: https://techgaun.github.io/active-forks/index.html#lkundrak/dev86

I assume the jbruchon fork would be the best choice.

Created attachment 850368 [details, diff]
dev86-clang16.patch

I started this with the best of intentions but I don't think I can devote much more time to this.  Aside from the clang-16 issues, there were a number of bcc runtime parsing errors that I'm not inclined to debug. I've attached the clang-16 fixes if anyone wants to continue.
