The private __align field makes it hard to construct an in6_addr.

rust-lang/libc#41 breaks the old code

Yeah for now I'd create instances with mem::uninitialized or mem::zeroed (as you would in C) and then set the fields manually. Unfortunately without a way to specify a custom alignment I don't know of a way around this :(

The good news though is that if we gain the ability to do so the code will be backwards compatible for when the private field is removed!
