            Bug ID: 119301
           Summary: cobol FE uses get_current_dir_name unconditionally
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Keywords: build
          Severity: normal
          Priority: P3
         Component: cobol
          Assignee: iains at gcc dot gnu.org
          Reporter: iains at gcc dot gnu.org
  Target Milestone: ---

I think we can fix this by falling back to getcwd() which libiberty provides if
it's not available on $host.
