Don't count pathless --extern options for unused-crate-dependencies warnings `--extern proc_macro` is used to add the proc_macro crate to the extern prelude for all procmacros. In general pathless `--extern` only references sysroot/standard libraries and so should be exempt from unused-crate-dependencies warnings. 2020-06-01 16:21:27 -07:00			`// Pathless --extern references don't count`
