I sometimes need "cracker" classes in MSEide and MSEgui to fix bugs and make 
extensinsions for FCL classes in order to access private fields (examples 
TDataset, TParam, TField, TFiler, TReader, TWriter, TComponent).
Is it guaranteed that the local definitions have the same layout as the 
definition in the FCL unit?
