Compare to this similar test in Nmap's scan_engine.cc:
if (scantype != CONNECT_SCAN && Targets[0]->ifType() == devt_loopback) {
log_write(LOG_STDOUT, "Skipping %s against %s because Windows does not support scanning your own machine (localhost) this way.\n", scantype2str(scantype), Targets[0]->NameIP());
return;
}
rndbit made a report--unfortunately we con't fix it, but we can make the
error message clearer.

This is a refactoring of target parsing that stores different types of
target specifications as different classes. The eventual intention is to
allow easy iteration over each specification for the purpose of IPv6
multicast host discovery.
Reworked the logging infrastructure to make it more flexible
and consistent.
Updated nmap, nping and ncat accordingly. Nsock log level can
now be adjusted at runtime by pressing d/D in nmap.
The exceptions are the calls in ncat/ncat_connect.c and
nping/EchoServer.cc. Ncat doesn't have an option for the interface, and
I think Nping's -e option is only meant to apply to probes, not to the
echo server listener.
This was an old library removed in r2811 and r2812, of which a few
traces remained.
I don't know the purpose of this in nbase_misc.c:
if(sd != 501) // Hack related to WinIP Raw Socket support
ioctlsocket (sd, FIONBIO, &one);
For some reason (probably by imitation of nmap_getservbyport), protocol
numbers, which are byte values 0–255, had htons called on them after
being read from nmap-protocols. On little-endian platforms, this turned
them into integers 0x0100, 0x0200, 0x0300, etc.
protocol_table is supposed to be an array of 256 linked lists, linking
all the protocol names of the same number. Because of the above htons
conversion, all protocols mapped to bucket 0 on lookup instead. Perhaps
in an attempt to work around this broken lookup, all protocols were
inserted into bucket 0 on init; all other buckets were empty. This
worked on little-endian platforms, but on big-endian platforms where
htons is a no-op, all protocol numbers but 0 mapped to an empty linked
list.
Remove all the htons stuff and just look things up by integers. Use the
same mapping on initial insertion and on lookup, so that the buckets are
acutally populated.
This was noticed by hejianet.

These aren't getting regenerated even with "aclocal --force"; I think
it's because there is nothing to put in them. Running "aclocal
--verbose" shows that all the required macros are in acinclude.m4 files:
aclocal: saw macro PCAP_IS_SUITABLE
aclocal: saw macro RECVFROM_ARG6_TYPE
aclocal: saw macro PCAP_IS_SUITABLE
aclocal: saw macro CHECK_IPV6_IPPROTO_RAW
aclocal: saw macro APR_FIND_APR
aclocal: ../acinclude.m4 is already included by configure.ac
