FWIW, I've added support for this in https://github.com/kinetiknz/rusty-cheddar/commit/bb819e501c9031ce62e409029c4ea5b2c736b633. I assume @Sean1708 won't want to merge it because rusty-cheddar is being replaced with rusty-binder, but we (https://github.com/mozilla/mp4parse-rust) need this to fix...

You can use `Cheddar::insert_code` to insert the license text, for example see https://github.com/mozilla/mp4parse-rust/blob/master/mp4parse_capi/build.rs. The only (slight) down side is that it's inserted *after* the two C99 headers.
