Interesting. I wonder how compiler-dependent rule 10 is. Like, if I'm writing for a compiler that gives really bad and usually unhelpful warnings that make my code worse... but I suppose these are more very strict guidelines than rules.

That section explicitly addresses that question and says you should rewrite it in a way that avoids the warning, since "usually unhelpful" means "sometimes critical". It's certainly an uncompromising view but that's what you get when failure is disastrous.
