Using .swc in Flash CS5

Question

I have a user who is having trouble using my library .swc in flash CS5.
I do not have CS5 to help him out much; but the .swc does work fine with mxmlc from the Flex SDK, as well as under flashdevelop using the Flex SDK. And although not this exact version of the .swc I have previously found it work fine under CS4 and have other users with CS3 who do not have any trouble.
under mxmlc, using the compiler options:
--include-libraries $(NAPE_BIN)/debug_nape.swc
There are no issues, and everything works as expected.
The error my user is receiving is about an undefined reference to a specific class contained in the .swc (DummyNapeMain)
This error appears also with mxmlc if I use the option --library-path instead of --include-libraries
I repeat the test case here if it will help to find a working configuration for CS5.
package {
     import flash.display.MovieClip;
     import flash.events.Event;
     import nape.util.*;
     import nape.space.*;
     import nape.phys.*;
     import nape.shape.*;
     import nape.geom.*;
     public class Main extends MovieClip {
          public function Main() {
               super();
               if(stage!=null)
                    addEventListener(Event.ADDED_TO_STAGE, init);
               else init(null);
          public function init(ev:Event):void {
               if(ev!=null) removeEventListener(Event.ADDED_TO_STAGE, init);
               haxe.init(null);
               var debug:Debug = new BitmapDebug(600,600,0x333333);
               addChild(debug.display);
               var space:Space = new Space(new Vec2(0,400));
               var walls:Body = new Body(BodyType.STATIC);
               walls.shapes.add(new Polygon(Polygon.rect(0,0,600,20)));              
               walls.shapes.add(new Polygon(Polygon.rect(0,600,600,-20)));              
               walls.shapes.add(new Polygon(Polygon.rect(0,0,20,600)));              
               walls.shapes.add(new Polygon(Polygon.rect(600,0,-20,600)));              
               walls.space = space;
               for(var i:int = 0; i<100; i++) {
                    var b:Body = new Body();
                    b.position.setxy(50+Math.random()*500,50+Math.random()*500);
                    b.shapes.add(new Polygon(Polygon.box(16,16)));
                    b.rotation = Math.random()*2*Math.PI;
                    b.space = space;
               addEventListener(Event.ENTER_FRAME, function (ev:Event):void {
                    space.step(1/60,10,4);
                    debug.clear();
                    debug.draw(space);
                    debug.flush();
the .swc is available at: https://github.com/deltaluca/nape/raw/master/bin/release/debug_nape.swc
Thank you.

I downloaded a CS5.5 trial to test this out myself.
The error does indeed happen with the test case;
my user found a hack to get around the error which is to do:
DummyNapeMain;
(just like that) to force the compiler to include it from the .swc and prevent the error occuring.
Why is there no way in Flash CS5/5.5 to have the entire .swc included without flash trying (and failing) to determine what does, and doesn't need to be included?
