[eigen] problem with operator() in development branch

[Bill Greene <w.h.greene@xxxxxxxxx>]

I'm running with a very recent version of Eigen from the development branch.
The following code snippet works fine with Eigen 2

  Eigen::MatrixXd a(1,2), b(2,1);
  a << 1, 2;
  b << 2, 3;
  double c = (a*b)(0,0);
  std::cout << "c=" << c << std::endl;

but I get a compilation error with VC++ 2008 and the development branch Eigen

d:\u_drive\src\eigen\dev_branch\eigen\eigen\src\core\densecoeffsbase.h(92)
: error C2248: 'Eigen::ProductBase<Derived,Lhs,Rhs>::coeff' : cannot
access private member declared in class
'Eigen::ProductBase<Derived,Lhs,Rhs>'
1>

Thanks.
