Determining procedure location programmatically?

Question

I have a 10g form that has a library attached. In the library there is a procedure that is defined both in the library and locally in the form with the same name. This worked ok in previous versions of Forms but according to Oracle Support there is a bug in 10g that causes Forms to get a 92101 error and the work around is to rename the procedure since there is no fix for the bug at the moment. However, for this application both procedures are needed since some of the forms have the procedure locally defined and others do not.
Is there any way to determine programmatically within a library whether a procedure exists locally? If so then I could rename the local procedure but call it from the library if it exists.

I don't think you can do this, but even if you can - it won't help you. You will still need procedure with the same name to be present in library for compilation.
You can try to use execute_trigger. Although, personally, I don't like this method.
In the form create user defined trigger instead of procedure.
In the library try something like this:
BEGIN
  copy('25','System.Message_Level');
  execute_trigger('form_user_def_trigg');  
  IF NOT FORM_SUCCESS then   
    library_procedure;
  END IF;   
  copy('0','System.Message_Level');      
END;
