I don't see an issue with it. I think I have seen some versions of ping
use a single binary for IPv4 and IPv6 and others use separate. I forget
which implementations do which. Perhaps the older ones use separate
binaries?  I'll have a look at merging them.

Also, I wonder if we can add some headers to gnulib. Currently Inetutils
has a "replacement" header for <netinet/ip_icmp.h>. This should be
available on BSD and GNU libc systems.

Likewise we check for arpa/{ftp.h,telnet.h,tftp.h} and define things if
they aren't available. Though those files have BSD licenses on them
which would likely mean messing with gnulib-tool...
