Bugzilla Bug 237893

ntp-4.2.4p5 was released August 18th, 2008.  Some highlights from the release
notes:

* [BUG 1051] Month off by one in leap second message written to clockstats
  file fixed.
* [Bug 841] Obsolete the "dynamic" keyword and make deferred binding
  to local interfaces the default.
  Emit a warning if that keyword is used for configuration.
* [Bug 993] Fix memory leak when fetching system messages.
* [Bug 987] Wake up the resolver thread/process when a new interface has
  become available.
* Startup code for original LinuxPPS removed.  LinuxPPS now conforms to
  the PPSAPI.
* [Bug 990] drop minimum time restriction for interface update interval.
* [Bug 977] Fix mismatching #ifdefs for builds without IPv6.
* Build system cleanup (make autogen-generated files writable).
* Fixes for ntpdate:
* [Bug 532] nptdate timeout is too long if several servers are supplied.
* [Bug 698] timeBeginPeriod is called without timeEndPeriod in some NTP tools.
* [Bug 857] ntpdate debug mode adjusts system clock when it shouldn't.
* [Bug 908] ntpdate crashes sometimes.
* [Bug 982] ntpdate(and ntptimeset) buffer overrun if HAVE_POLL_H isn't set
  (dup of 908).
* [Bug 997] ntpdate buffer too small and unsafe.
