When I try to include both Boost.Range algorithms (in the current trunk 
version) and Boost.Algorithm, using a file such as the following:

#include <boost/algorithm/string.hpp>
#include <boost/range/algorithm.hpp>

I receive several errors about duplicate definitions.  I am using gcc 
4.1.2 on Linux.

./boost/range/algorithm/find.hpp:28: error: ¡template<class 
SinglePassRange, class Value> typename boost::range_iterator::type 
boost::find(SinglePassRange&, const Value&)¢ conflicts with previous using 
declaration ¡template<class RangeT, class FinderT> 
boost::iterator_range<typename boost::range_iterator<C>::type> 
boost::algorithm::find(RangeT&, const FinderT&)¢
./boost/range/algorithm/lexicographical_compare.hpp:28: error: 
¡template<class SinglePassRange1, class SinglePassRange2> bool 
boost::lexicographical_compare(const SinglePassRange1&, const 
SinglePassRange2&)¢ conflicts with previous using declaration 
¡template<class Range1T, class Range2T> bool 
boost::algorithm::lexicographical_compare(const Range1T&, const Range2T&)¢
./boost/range/algorithm/lexicographical_compare.hpp:42: error: 
¡template<class SinglePassRange1, class SinglePassRange2, class 
BinaryPredicate> bool boost::lexicographical_compare(const 
SinglePassRange1&, const SinglePassRange2&, BinaryPredicate)¢ conflicts 
with previous using declaration ¡template<class Range1T, class Range2T, 
class PredicateT> bool boost::algorithm::lexicographical_compare(const 
Range1T&, const Range2T&, PredicateT)¢

The using declarations mentioned in the error message are in files such as 
boost/algorithm/string/find.hpp.  Is there a workaround or easy fix for 
this?
