Why is errno being set to 0?

The C APIs don't promise to clear errno on input; you have to do that yourself.

Why is errno's value then tested to see if it's not zero?

Looks like this have been that way since December 1999 when Fred added it.

Looks like a bug to me. It should be set just before confstr() is called.
