            Bug ID: 106425
           Summary: implicit-int
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: muecker at gwdg dot de
  Target Milestone: ---

With C23 having auto, we should consider making -Wimplicit-int a hard error in
previous versions after C90 to catch invalid code that may change behavior.

At least where implicit int is combined with auto.
