            Bug ID: 81264
           Summary: fixincludes/fixincl.c fails on DEBUG build
           Product: gcc
           Version: 6.3.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: mario at emmenlauer dot de
  Target Milestone: ---

fixincludes/fixincl.c reads in line 1123:
              fprintf (stderr, z_failed, _ttyp, p_fixd->fix_name,       \
                       pz_fname, p_fixd->test_ct - test_ct);

The variable z_failed is undefined.

This is not a critical issue as it only appears if DEBUG is defined.
But AFAIK its still a bug, so I wanted to report it.
