Report this bug to IBM: the AIX headers are defining the structs wrong.
You can quote RFC 3493 - Basic Socket Interface Extensions for IPv6
section 3.10:

One simple addition to the sockets API that can help application
writers is the "struct sockaddr_storage". This data structure can
simplify writing code that is portable across multiple address
families and platforms. This data structure is designed with the
following goals.

- Large enough to accommodate all supported protocol-specific address
structures.
