 We now require a newer version of Boost. This has caused various build
 failures on different platforms. This is one of them:

 `boost::lexical_cast` fails compile on Solaris with SunStudio:

 Brief analysis:

 The copy constructor is indeed private, but I don't see why it would be
 used in this case. Is it trying to make a new non-const instance out of
 the const reference during lexical_cast<std::string,
 isc::dns::AbstractRRset> due to the guessed template argument being
 non-const?
