        * dependency.c (gfc_check_argument_var_dependency): Add
        elemental check flag. Issue a warning if we find a dependency
        but don't generate a temporary. Add the case of an elemental
        function call as actual argument to an elemental procedure.

        Update call to gfc_check_argument_dependency.
        * trans-stmt.c (gfc_trans_call): Make call to
        gfc_conv_elemental_dependency unconditional, but with a flag
        whether we should check dependencies between variables.
