Can any experts in MWCW take a look at why libs/type_traits/extent_test.cpp fails all the tests? The implementation of the extent type trait is pretty simple, and Metrowerks is the only compiler that doesn't like it for some reason.

It doesn't differentiate between these two types of PTS structs... template <class T, std::size_t R> struct extent_imp<T[R],0> { BOOST_STATIC_CONSTANT(std::size_t, value = R); }; template <class T> struct extent_imp<T[], 0> { BOOST_STATIC_CONSTANT(std::size_t, value = 0); }; And it picks the second all the time for int[n][m] and int[][]. Don't know what can be done about it though.
