Following example fails on Intel C++ 7.0 and 8.0 (both Windows,
plugged into VC6 IDE, using old Dinkumware) and 1.31 RC1:

________________________________
#include <boost/type_traits/is_class.hpp>

int main()
{
    typedef const int an_array[10]; // remove const and it will compile
    bool b = ::boost::is_class<an_array>::value;

 return 0;
}
________________________________

with error:

It works with VC++6.5, it works with Intel C++ 7.0 and 8.0 _and_ Boost
1.30.2.
