        * array.c (match_array_element_spec): If the length of an array is
        negative, adjust the upper limit to make it zero length.

        PR fortran/30660
        * resolve.c (pure_function, resolve_function): Initialize name to
        null to clear up build warnings.
        (resolve_fl_variable): Look at components explicitly to check for
        default initializer, rather than using gfc_default_initializer.
