hmmm... sorry for raising more questions, but does it mean that
also ast_event_ie has the same restrictions as ast-event (cannot
be changed as it has to match the wire format) ?

in any case, if there is such a restriction (surely for struct ast_event,
possibly for struct ast_event_ie) then the definition should not
be here but in a common place so we make sure that chan_iax and
event.c use the same layout.
