- * Note: ai_addrlen used to be a size_t, per RFC 2553.
- * In XNS5.2, and subsequently in POSIX-2001 and RFC 3493 it was
- * changed to a socklen_t.
- * To accomodate for this while preserving binary compatibility with the
- * old interface, we prepend or append 32 bits of padding, depending on

- * This should be deleted the next time the libc major number is
