[Bug c++/19542] attribute(sentinel) has problems with C++ __null

__null is 0 of integer type, while attribute sentinel checks for 0 of pointer 
type. Remember this is not the same because it depends on the ABI: on some 
platforms, pushing a 0 of integer type into the stack for a call is different 
from pushing a 0 of pointer type. In fact, using __null for (eg) concat() is 
actually a real bug.
