* in which case using & (address-of) on it or taking sizeof()
* wouldn't go over too well.  (Those are not attempted
* now but in case someone thinks to change the below code
* to use addr.s_addr instead of addr, you have been warned.)
*
* Bad Assumption 3: the s_addr is the first field in
* an in_addr, or that its bytes are the first bytes in
* an in_addr.
*
* These bad assumptions are wrong in UNICOS which has
* struct in_addr { struct { u_long  st_addr:32; } s_da };
