Eh? I'm fairly sure that if the macro is defined, standard containers
are replaced by their debug counterpart. This is all you need to do to
enable debugging (I have caught many bugs in my code just by defining
that macro).

In fact IIRC debugging containers are always available even if you do
not define the macro and you can access them by explicitly using the
__debug namespace (but I've never done that).
