Including boost/range/numeric.hpp causes compile errors without defining NDEBUG

[Naoki Yoshioka <yoshioka.naoki@…>]

Although boost::inner_product in boost/range/numeric.hpp calls a function template boost::distance for static asserting, the header file has no statement to include boost/range/distance.hpp. Therefore, for example, the following code cannot be compiled without -DNDEBUG option.

// test.cpp
#include <boost/range/numeric.hpp>

int main()
{
  int array[3] = {0, 1, 2};
  boost::accumulate(array, 0);

  return 0;
}

The errors are as follows;
