Struct nc::msghdr_t

#[repr(C)]
pub struct msghdr_t {
    pub msg_name: usize,
    pub msg_namelen: i32,
    pub msg_iov: *mut iovec_t,
    pub msg_iovlen: size_t,
    pub msg_control: usize,
    pub msg_controllen: size_t,
    pub msg_flags: u32,
}

As we do 4.4BSD message passing we use a 4.4BSD message passing system, not 4.3. Thus msg_accrights(len) are now missing. They belong in an obscure libc emulation or the bin.
