    fortran: Object types should be declared before use in NAMELIST.

    gcc/fortran/ChangeLog:

            PR fortran/98686
            * match.c (gfc_match_namelist): If BT_UNKNOWN, check for
            IMPLICIT NONE and and issue an error, otherwise set the type
            to its IMPLICIT type so that any subsequent use of objects will
            will confirm their types.
