            Bug ID: 90160
           Summary: missing quote in diagnostic
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: translation
          Assignee: unassigned at gcc dot gnu.org
          Reporter: roland.illig at gmx dot de
  Target Milestone: ---

From arm.c:

        error ("%s incompatible with %<-mword-relocations%>", flag);

The first %s is also a command line option and thus should be %qs.
