     Type:  Bugs                     |      Status:  new         
Milestone:  Boost 1.35.0             |   Component:  accumulator 
  Version:  Boost Development Trunk  |    Severity:  Showstopper 
 Keywords:                           |  
-------------------------------------+--------------------------------------
 we discovered a conflict between the Interval and Accumulator library. The
 following code:
 {{{
 #!cpp
 #include <boost/numeric/interval.hpp>
 #include <boost/accumulators/accumulators.hpp>
 #include <boost/accumulators/statistics.hpp>
 }}}
 gives the error message:
 {{{
 /Users/troyer/src/boost/boost/accumulators/numeric/functional_fwd.hpp:205:
 error: declaration of template ‘template<class T> struct
 boost::numeric::empty’
 /Users/troyer/src/boost/boost/numeric/interval/utility.hpp:98: error:
 conflicts with previous declaration ‘template<class T, class Policies>
 bool boost::numeric::empty(const boost::numeric::interval<T, Policies>&)’
 }}}

 It seems that boost::numeric::empty is defined in both libraries.

 We think this needs to be resolved before the release goes out.
