Wrong. errno is in fact on most systems a hidden function call and the
C language does not have any provisions to say that a function call can
be eliminated because it always returns the same value and has no side
effects. We have such a feature in gcc but it's not evailable
everywhere.

And the fact that you don't make copies in APR anywhere does not mean
anything.
