This undertaking has been successful, and it also uncovered
the serious mistakes corrected in "24f0cb05". Most recently
the implementation of "--ip-timestamp" proved to be a most
useful step forward, as it makes interesting probes possible.

As a next step I would like to collect code related to IP options
into a separate part, since "ping" as well as "traceroute" are
immediate consumers of such code. I would also refactor code
from "ping/ping_echo.c" into that construct. The most urgent
intention of mine is to implement Loose source record route,
LSRR, for "ping" as well as "traceroute". We need this!
It would also simplify the implementation of IP option Timestamp
in the "prespec" variation.

Two paths are available:

   * A new helper library "libip/libip.a".

   * Local object file "ping/libip.o", which would have
     to be included with "src/traceroute.o".

The first seems the best. Objections?

Best regards,
  Mats E A
