Just found one workaround:
1. use flasm -d TestDemoLucky.swf > TestDemoLucky.flm
2. remove these code:
   push 'TestDemoLucky'
   getVariable
   not
   not
   branchIfTrue label11
3. flasm -a TestDemoLucky
Don't know how to do it in mtasc way.

The problem is that it's not compatible with Adobe AS2 compiler, which
never overwrite a class if it's already defined. This is why this jump
to the class end is needed.

Thanks, Nicolas.
So there's not any way/workaround to "check if defined" without a warning?

Currently no, although it would be possible to add a compilation flag
for this. The problem is that there is still other limitations in the
player bytecode, such as function size, which cannot be avoided.

Thank you for the tips.
Seems I have to forget about the scaring warnings. :)
