Update: in the absence of SFINAE expression support, a number of type_traits are terminally broken, and this is one I'm afraid.

If this is unimplementable, then that's fine. What I find confusing is that regression tests for is_nothrow_move_assignable pass on this compiler: http://www.boost.org/development/tests/develop/developer/type_traits.html

The compiler has an __is_nothrow_assignable() built-in, which seems usable here. The standard says that is_nothrow_move_assignable<T> is the same as is_nothrow_assignable. Bo Persson
