4905	Implementation of boost::range::map_keys should use boost::range_reference	ru.elric@…	Neil Groves	"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."	Patches	closed	Boost 1.46.0	range	Boost 1.45.0	Optimization	fixed
