* 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

* To accomodate for this while preserving binary compatibility with the
* old interface, we prepend or append 32 bits of padding, depending on
* the (LP64) architecture's endianness.
*
* This should be deleted the next time the libc major number is
* incremented.
