5556	Compilation error in boost::range with GCC 4.5	ru.elric@…	Neil Groves	"The following code:
{{{
#include <boost/range/algorithm.hpp>
#include <boost/range/algorithm_ext.hpp>

int main() {
  return 0;
}
}}}
produces the following compilation error:
{{{
$ g++ main.cpp
In file included from boost/range/algorithm_ext.hpp:20:0,
                 from cppmain.cpp:2:
boost/range/algorithm_ext/is_sorted.hpp: In function 'bool boost::range::is_sorted(const SinglePassRange&)':
boost/range/algorithm_ext/is_sorted.hpp:55:12: error: 'is_sorted' is not a member of 'boost::range::range_detail'
}}}

Note that changing include order makes the error go away. I believe it's due to a fact that one of the headers included by `<boost/range/algorithm.hpp>` defines a `boost::range::range_detail` namespace, which is then looked up for `is_sorted` implementation that is not there."
