--- Comment #4 from kargl at gcc dot gnu.org --- OK, How about WONTFIX? If the programmer fixes the issue reported in the "duplicate" error message, then the problem goes away. Amazing what an error message can convey! PS: The first duplicate error can be fixed by a trivial 3 character patch. The second duplicate error will probably take a significant rewrite of how labels are handle. Good luck.
