That article seems to have a good summary, yeah. Going through char *
fixes it, but honestly, I prefer the approach of breaking out the
aliased types into small (theoretically inline-able) functions. The
in_addr_to_sockaddr_storage function is actually a great example of how
to avoid aliasing issues - it handles the messy aliasing of the
sockaddr_storage struct so that the caller doesn't get bitten. Many
times you can write little wrappers like that.
