It says a lot that this document has to include things like this:
> Only cast if confident it's correct, otherwise investigate more. Casts will silence real problems if incorrectly used.
> Do not assume it is supposed to be an int.
> Do not simply cast to the "other side" of the error. Casts will silence warnings/errors, but that does not mean the cast is correct.
Besides the increasingly well-known footguns of old C code, we're always going to have problems if there isn't an inherent safety culture among the people maintaining open source projects, whether as upstream or a distributor.
