No, back to this one please.  ;-)

Apparently, the changes you prepared for existing testcases did not get
committed, so I'm now seeing some FAILs there.  See also recent posts on
the <gcc-regression@gcc.gnu.org> mailing list:

    FAIL: gfortran.dg/gomp/associate1.f90   -O  (test for excess errors)
    FAIL: gfortran.dg/predcom-1.f   -O  (test for excess errors)
    FAIL: gfortran.dg/unconstrained_commons.f   -O  (test for excess errors)

And the following gets highlighted, too:

    FAIL: compiler driver --help=fortran option(s): "^ +-.*[^:.]$" absent from output: "  -Wdo-subscript              Warn about possibly incorrect subscripts in do loops"
    FAIL: compiler driver --help=warnings option(s): "^ +-.*[^:.]$" absent from output: "  -Wdo-subscript              Warn about possibly incorrect subscripts in do loops"
