        * defs.h (struct continuation_arg): make 'data' a union, to avoid
        casting problems when int and pointer are not the  same size.
        * event-top.c (command_handler): use data as a union.
        (command_line_handler_continuation): ditto.
        * infcmd.c (step_1_continuation): use data as a union.  Re-indent.
        (step_once): ditto.  (finish_command_continuation): ditto.
        (finish_command): ditto.
        * breakpoint.c (until_break_command): use data as a union.
        (until_break_command_continuation): ditto.
        * utils.c (add_intermediate_continuation): fix typo in comment.
