            Bug ID: 82711
           Summary: -Wignored-qualifiers could be moved into -Wextra
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: sylvestre at debian dot org
  Target Milestone: ---

Compiling Firefox, we fixed several warnings found by -Wignored-qualifiers

I wonder if this option should not be moved under -Wextra.
The extra const isn't hurting and in a way improves readability.
