i have trouble with reading ublas matrix from input stream.

after quite long googling, i came to read the previous posting in this
mailing list:

After this posting, is there any progress with this??

in case you cannot read the above link. my problem in detail is as
following:
and the cause of problem is as stated in the link:
> STL shipped with VC2005 does not support
> extraction of numbers separated with anything but whitespace
so the size of matrix enclosed by [ and , ( as in [3,3]) cannot be read.
code:
#include <fstream>
#include <boost/numeric/ublas/matrix.hpp>
#include <boost/numeric/ublas/io.hpp>
namespace ub=boost::numeric::ublas;
int main(int argc, char* argv[])
{
ub::matrix<int> data;
data.resize(3,3);
for (int i=0 ; i<3 ; i++)
{
for (int j=0 ; j<3 ; j++)
{
data(i,j)=i*j;
}
}
std::ofstream ofs("data.txt");
ofs << data << "\n";
ofs.close();
ub::matrix<int> out;
std::ifstream ifs("data.txt");
ifs >> out;
std::cout << out << "\n";
return 0;
}
g++ on linux, this gives
[3,3]((0,0,0),(0,1,2),(0,2,4))
but with vc8.0 this gives
[0,0]()
