Arguably, that's the sanest one: you can't expect the old C code to follow the rules of the new versions of the language. In a better world, each source file would start with something like
#pragma lang_ver stdc89
On the topic of the article, yeah, sticking anything other than 0 or 1 into C99 bool type is UB. Use ints.

Well, to be pedantic, the entire point of the C standard, and the standard body, is that you should expect it to work, as long as you're working within the standard!
Yeah, it’s only kicking the can down the road if you’re the actual maintainer of the software.
If you’re just a packager, it’s your job to get the package to build and work correctly; for your own sanity, you should be making minimal changes to the underlying code to facilitate that. Get it building with the old language version and file a bug report.
