AIR classes don't compile with CompC

I’ve been using compc with ANT to compile some of my class files into SWC files. This all works well, until any of the classes to be compiled contain a reference to any of the AIR classes. At this point I start getting the following type of error:

col: 39 Error: Type was not found or was not a compile-time constant: NativeWindow.
col: 46 Error: Type was not found or was not a compile-time constant: File.
col: 23 Error: Definition flash.desktop:NativeApplication could not be found.

It only seems to be any of the AIR packages/classes that cause a problem, so I’m really hoping they are not just simply exempt from compilation.

If anyone knows how I can get around this, I would very much appreciate the help.

Thanks.
