Hello,

Here, all tests compile with GCC 4.7.0.

However, I get the following warning:

boost-trunk/boost/numeric/ublas/storage.hpp:1755:9: warning: base
class ‘class boost::noncopyable_::noncopyable’ should be explicitly
initialized in the copy constructor

At the following line, there is the definition of the public
copy-constructor of the index_triple class.
Is it OK that this class, which inherits from boost::noncopyable,
defines a copy-constructor?

Cheers,
