The following patch solves the bad array type being picked up in the call_traits tests, leaving one test unsolved. It also confirms the workarounds are still needed for BCB2006. Note the minor case of switching order of T and const. This is due to a bug I only fully appreciated today. depending on order of add_const and add_ref, BCB will deduce 2 *different* types. int const & int & const The latter does not sound like a 'real' type to me, so I suggest always placing const before the type, rather than after, when dealing with template type-parameters - unless we have cases where this makes a real difference for conforming compilers. Rest of the patch should be straightforward.
