Lots of warnings during build

[jdm]

Every time I do cargo build or cargo run a screenful of warnings is printed out for that project. Is there a way to suppress this?

@gyorokpeter Could you include the actual warning output in this issue?

[gyorokpeter]

Normally it also includes some unused parameters, but I have already changed the code to suppress those locally, hoping that would be enough, but it wasn't.
