SMCRoute v2.1.1

Changes

• When SIGHUP is received SMCRoute now touches its PID file as an
  acknowledgement. This is used by some process supervision daemons,
  like Finit, on system
  configuration changes to detect when a daemon is done. The mtime is
  set using the utimensat() function to ensure nanosecond resolution.

Fixes

• Fix issue #38: Minor memory leak at exit. The Valgrind tool warns
  that all memory is not freed when smcroute exits. On most modern
  UNIX systems, on platforms with MMU, this is not a problem, but on
  older systems, or uClinux, memory is not freed at program exit.
• Fix issue #39: Removing wildcard route at runtime does not work if no
  kernel routes have been set.
• Fix issue #44: IPv6 disabled by default, despite what configure says
  in its help text. Enabling it disables it ... fixed by enablig IPv6
  by default.
