347*
348* Bad Assumption 2: the s_addr field is a simple type
c2654555 349* (such as an int, u_int32_t). It can be a bit field,
2528d3bc

350* in which case using & (address-of) on it or taking sizeof()
351* wouldn't go over too well. (Those are not attempted
352* now but in case someone thinks to change the below code
353* to use addr.s_addr instead of addr, you have been warned.)
354*
355* Bad Assumption 3: the s_addr is the first field in
356* an in_addr, or that its bytes are the first bytes in
357* an in_addr.
358*
359* These bad assumptions are wrong in UNICOS which has
