[Boost-users] [ublas] warning on VC9 about checked iterators

Hello,

Using Boost 1.37.0, I compile the following program under VC9 (VS .NET
2008 Express Edition):

#include <boost/numeric/ublas/vector.hpp>

class Host
{
public:
        Host(const boost::numeric::ublas::bounded_vector<double,3>& normal) :
normal_(normal) {}
private:
        boost::numeric::ublas::bounded_vector<double,3> normal_;
};

int main()
{
        return 0;
}

and I get the following warning:

1>c:\boost\boost_1_37_0\boost\numeric\ublas\storage.hpp(337) : warning
C4996: 'std::copy': Function call with parameters that may be unsafe -
this call relies on the caller to check that the passed values are
correct. To disable this warning, use -D_SCL_SECURE_NO_WARNINGS. See
documentation on how to use Visual C++ 'Checked Iterators'

1>            N=3
1>        ]

Should I compile with -D_SCL_SECURE_NO_WARNINGS? Is there a fix coming
for ublas? What do others do?

Regards,

Pete
