4051	[range][string_algo] Conflict between algorithm names	Jeremiah Willcock	Marshall Clow	"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&)’

}}}

The using declarations mentioned in the error message are in files such as boost/algorithm/string/find.hpp."	Bugs	closed	Boost 1.43.0	algorithm	Boost Development Trunk	Problem	fixed
