Jonathan,
Isn't that what Remi said? I believe his two solutions were
to be employed simultaneously, not as an "either/or" set of
options. It would certainly make sense.
Also, actually, including stddef.h brings the symbols into
the `std` namespace *and* the global namespace. See D.5 in 2003.
cstddef is indeed preferred, though.
