It's not in 4.3BSD either, and if __USE_MISC is intended to be 
restricted to those definitions (or those of similar vintage), then 
__USE_MISC would not be correct.

If __USE_MISC is free to involve, pretty much like __USE_GNU, then this 
is not a problem.  But it's not clear to me if this is the intent.
