True, but I can hardly think of a situation where this
might be a problem.

As far as I understood the requirement:

- Thread A (or an interrupt) posts an event.

- Thread B initiates something and wants to wait for
the event exactly caused by _this_ initiation, not any
previously posted one.

The most difficult situation is probably when the
event is posted by an interrupt. Thread B:

   NutEnterCritical
   NutEventBroadcast
   Initiate something
   NutEventWait
   NutExitCritical

Don't get me wrong. I'm not against additional API calls.
I'm just unable to see the requirement here and can't think
of a situation where NutEventBroadcast would hurt.

IMHO, NutEventClear would be a misleading name. Let's
consider NutEventClearSignaled.
