   Very good reading. Thank you! I notice that <netinet/tcp.h> is mentioned,
   but not <netinet/udp.h>, which seems awkward.

Yeah. :/

   Admittedly, I now appreciate Alfred's point of view, but I would
   like to understand better what impacts are circumvented by
   nourishing a private header like <libicmp/icmp.h>.

My main concern is that libicmp is something we can control, and
extend without fear of ending up on a b0rked system where something
will do something that we don't want to.

Indeed, I'd almost want to not depend on anything non-POSIX or
non-standardised in IU; but life is life... :-)
