In the error message when a label was defined that had already been defined, put the location (source file, line number) of the original location.
Rationale: in large code bases with many blocks, it might be that a label has been defined really elsewhere and difficult to find even with search (if you don't expect it there). A hint where this label has been defined before would be very helpful
