Compile error with boost 1.34

[Keir Mierle]

When compiling with boost 1.34, I get the following error:
namespace ublas = boost::numeric::ublas;
using ublas::range;

typedef ublas::matrix<double> mat;
typedef ublas::vector<double> vec;

typedef ublas::matrix_range<mat> submat;
typedef ublas::vector_range<vec> subvec;
typedef ublas::matrix_vector_range<mat> submatvec;
typedef ublas::identity_matrix<double> eye;

vec sphere_to_disk(const vec &P)
{
 double norm = norm_2(P);
 int n = P.size();

 double fudge, nx, sign;
 if (P[n-1] < 0.0)
  sign = -1;
 else
  sign = 1;

 nx = 2*acos(sign*P[n-1]/norm);
 if (nx != 0.) {
  fudge = sign*nx/norm/sin(nx/2);
 } else {
  fudge = 0.0;
 }

 vec R(n-1);
 for (int i=0; i<n-1; i++)
  R[i] = fudge*P[i];

 assert(norm_2(R) < M_PI + 1e-10);

 return R; // ERROR HERE????
}

Fixed by patching storage.hpp in Boost 1.34. Not sure if this patch will cause problems.
