  Changes v1.x to v2.x re-worked a number of the internal structures.
So I'm not surprised that some more warnins crept back in.

  That being said, v1.x had a *lot* of warnings.  v2.x has very, very, few.

  And unlike ISC DHCP, we won't build by default with -Werror.
Different versions of GCC have different opinions about warnings.  So
what works in the ISC development system results in build failures on my
system, for minor compiler warnings.
