This avoids an unhelpful warning from a system header. Users can't
change the code to avoid the warning, and we don't want to change it
(because it needs to work for C++98 as well as later versions).

	PR c++/82039
	* include/ext/new_allocator.h (__gnu_cxx::new_allocator::allocate):
	Adjust null pointer constant to avoid warning

Tested powerpc64le-linux, committed to trunk.
