            Bug ID: 125558
           Summary: [17 Regression] -Wstrict-overflow= is not recognised,
                    should be ignored
           Product: gcc
           Version: 17.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: slyfox at gcc dot gnu.org
  Target Milestone: ---

Noticed as a build failure of `libselinux` against r17-1145-g9700bdca4d97e7
(did not bisect yet):

$ gcc/xgcc -B gcc -c a.c -Wstrict-overflow
$ gcc/xgcc -B gcc -c a.c -Wstrict-overflow=5
xgcc: error: unrecognized command-line option ‘-Wstrict-overflow=5’; did you
mean ‘-Wstrict-overflow=’?
