Why does C2Rust produce so much incorrect code? Getting 5% wrong sounds terrible, for a 1:1 translation to unsafe Rust. What does it mis-translate?

> As for C2Rust, the 5% unsuccessful translations were due to compilation errors, the majority of them caused by unused imports.

I'm rather confused what that means, since unused imports cause warnings, not errors in Rust.
