It turns out that the only code that uses it is "pcap_lookupdev()",
a/k/a "pick some interface and give me its name"; "libpcap" itself
doesn't use it, it just exports it, "tcpdump" uses it only if you don't
explicitly tell it what device to use, and Ethereal doesn't use it at
all, so if it's broken, the only effect would be that you'd have to give
"tcpdump" a "-i" flag - it'd probably complain if you didn't.

Any idea what the right test should be to see whether to use SIOCGIFCONF
or OSIOCGIFCONF?  Is there a built-in ifdef we should use (e.g., AIX),
or do we need to put in, say, a configure-script test?
