__aligned(4) won't affect struct addrinfo since the sockaddr immediately
follows a socklen_t, which is 32 bits wide and has 32-bit alignment.  A
sockaddr_* allocated with malloc() will already be aligned, and so will
a sockaddr_* created on the stack.  The only problem is sockaddr_un,
because its size is not a multiple of 4, so if you allocate an array of
sockaddr_un, every other element will be misaligned.
