You're right, I apologize.  I totally missed the USG use of opterr and have
updated my code appropriately.  I am currently trying to get 4.3 to use
the correct code.

Not true.  The size difference between:

	main() { puts("foo"); }
and
	main() { write(0,"foo",3); }

is exactly zero.

Amen, I didn't know about it in January or I would have said something when
Berkeley asked to use mine.
