Warning for external methods that don't have an implementation

I’m using pas2js and a major portion of my project references external JavaScript functions. So I’m faced with a large amount of warnings when I use ‘external name' syntax for procedures/functions.

The warnings I’m getting are 'Implementation is missing for <external_method_name>'.

The project compiles successfully, it’s just an annoyance to see 100’s of warnings with no known work-around.
