But if we port our code to some other system where INADDR_ANY is perhaps not a zero, we need to assign it to `sa.sin_addr.s_addr`. Most modern C compilers are clever enough to notice that INADDR_ANY is a constant. As long as it is a zero, they will optimize the entire conditional statement out of the code.help
