        * dependency.c (gfc_check_argument_var_dependency): Use enum
        value instead of arithmetic vaue for 'elemental'.
        (check_data_pointer_types): New function.
        (gfc_check_dependency): Call check_data_pointer_types.
        * trans-array.h : Change fourth argument of
        gfc_conv_array_parameter to boolean.
        * trans-array.c (gfc_conv_array_parameter): A contiguous array
        can be a dummy but it must not be assumed shape or deferred.
        Change fourth argument to boolean. Array constructor exprs will
        always be contiguous and do not need packing and unpacking.
        * trans-expr.c (gfc_conv_procedure_call): Clean up some white
        space and change fourth argument of gfc_conv_array_parameter
        to boolean.
        (gfc_trans_arrayfunc_assign): Change fourth argument of
        gfc_conv_array_parameter to boolean.
        * trans-io.c (gfc_convert_array_to_string): The same.
        * trans-intrinsic.c (gfc_conv_intrinsic_loc): The same.
