We get a few warnings about unused items, because we no longer compile our `_start` function. To silence such unused code warnings, we can add the following to the top of our `main.rs`:
```
#![cfg_attr(test, allow(dead_code, unused_macros))]
#![cfg_attr(test, allow(dead_code, unused_macros, unused_imports))]
```
Like before, the `cfg_attr` attribute sets the passed attribute if the passed condition holds. Here, we set the `allow(…)` attribute when compiling in test mode. We use the `allow` attribute to disable warnings for the `dead_code` and `unused_macro` _lints_.
