Re: ITL 4.0.0-1 with MTL 2.1.2-21

You are right -- Somehow the change made in the classical gram schmidt
class was accidentally mixed with function get_data() required in
itl_to_BLAS interface.

Well, one quick way to fix is have following function:

template <class Vector, class VecRef, class Indexer>
typename Vector::value_type* 
get_data(const mtl::oned_part<Vector,VecRef,Indexer>& v) 
{
  typedef mtl::oned_part<Vector,VecRef,Indexer> V;
  V& vref = const_cast<V& >(v);
  return &(vref.get_ref(0));
}
