  16:  * which figures out the name of the local system.
  17:  * However, we do it by reading the file /usr/include/whoami.h.
  18:  * This avoids having to recompile uucp for each site and hence
  19:  * avoids having to distribute the source to uucp to people who
  20:  * have only binary licenses.
