Is struct assignment even _supposed_ to work?  I thought that was
"unwarranted chumminess with the compiler", to stretch the phrase a bit
beyond its original use.  (I've always been a bit depressed to see the
amount of code that just pointer-casts and struct-assigns structs out
of byte buffers, and have been careful to use bcopy myself.  Not
specifically for SIOCGIFCONF, but that's one example of an endemic
disease; other examples are things like routing socket messages.)
