Fun compiler fact: both GCC and clang rewrite x < C to x <= C-1 (for integers) as C-1 may require fewer bits to represent.

I would have thought that invoking a C compiler would be a solved problem. Looking at Rust's cc crate there's a remarkable long tail of corner cases to fix.
Exotic CPUs, microarchitectures, compiler differences, operating system differences, etc.
Today I learnt that `cargo fix` won't fix code with compiler errors by default, but you can override this!
$ cargo fix --broken-code --allow-dirty && cargo clippy --fix --allow-dirty
This incantation does exactly what I wanted :)
