For this specific type of problem (i.e., a false warning that trigger
-Werror failure), I suggested this:
http://bind10.isc.org/ticket/1671

If we want a more automatic way, we could detect the compiler bug with

AC_TRY_COMPILE([boost::numeric_cast<uint16_t>(length);])

but if it's only due to an internal patch to the compiler on a
particular version of particular OS, I'm not sure if it's worth the
additional hack in configure.ac.

We might also report it to FreeBSD.
