* bus/services.c (bus_service_list_queued_owners):
        Add a pointer cast to fix compiler warning

        * dbus/dbus-dataslot.c (_dbus_data_slot_list_get):
        return a NULL instead of FALSE since the return type
        is not expecting a boolean

        * dbus/dbus-marshal-basic.c (_dbus_marshal_test):
        Remove unused variable

        * dbus/dbus-marshal-recursive-util.c (node_new):
        return a NULL instead of FALSE since the return type
        is not expecting a boolean

        * dbus/dbus-server-debug-pipe.c (_dbus_transport_debug_pipe_new):
        Send a NULL into _dbus_transport_new_for_fd instead of a FALSE
        because we are expecting a pointer not a boolean

        * dbus/dbus-sysdeps-util.c (_dbus_get_tmpdir):
        add void as the parameter so some compilers
        don't complain

        * dbus/dbus-transport-unix.c (_dbus_transport_new_for_domain_socket,
          _dbus_transport_new_for_tcp_socket):
        Send a NULL into _dbus_transport_new_for_fd instead of a FALSE
        because we are expecting a pointer not a boolean

        * test/shell-test.c (test_command_line):
        cast the second argument to _dbus_list_append to avoid compiler
        warnings

        * test/test-names.c (main): remove unused variable

        * test/test-service.c (check_hello_from_self_reply):
        Initialize echo_message and echo_reply to NULL

        * test/test-shell-service.c (handle_echo):
        Remove unused variable and cast the third parameter passed to
        dbus_connection_get_object_path_data to avoid compiler warrnings

        * test/name-test/test-names.c (clear_message_queue):
        Remove unused function

        * test/name-test/test-pending-call-dispatch.c:
        Fix format string in printf
