--- Comment #8 from Manuel López-Ibáñez <manu at gcc dot gnu.org> 2012-11-19 16:50:34 UTC --- (In reply to comment #7) > Would that make sense in the grand scheme of things? The idea seems good. It would also handle comment #4 testcase. However, I am not sure how you would implement this. A different issue is why the macro unwinder cares about system-headers? See comment #3.
