-Wcast-align will warn about legitimate code.
Maybe there's some way to say "yes, I know that the pointer being cast
is appropriately aligned", or maybe some platforms say "yes, I know,
this is a struct sockaddr *, but those are aligned well enough for any
other socket address types", in which case we might be able to turn that
on by default in some cases.
