Hello,

running the test below, I see on glibc-2.17 armv5tel-linux:
----
Running net-db.test

;;; (err -11)
unexpected error code: -11 "System error"
FAIL: net-db.test: getaddrinfo: no name
----

I mention glibc 2.17 because I think it didn't fail with glibc 2.13.

Regards,
Lluís.

I went ahead and documented the missing errno value for EAI_SYSTEM.
