 The following thread provides detailed background for the problem:
 http://thread.gmane.org/gmane.comp.lib.boost.devel/211127


 This patch simply replaces the usage of boost::range_value<Range>::type&
 with boost::range_reference<Range>::type in the implementation of
 select_first, select_second_mutable and select_second_const functors from
 boost::range_detail namespace. I did not run the regression tests, but I
 believe there's nothing to get broken here.
