:-)

It only occurs to me now (rather than when I first suggested this
change) that it changes behaviour for users who have replaced operator
new, but not replaced the nothrow_t version.

But I can't believe that anyone would replace operator new *just* to
alter the behaviour of std::ios pword/iword allocation, and the
precise form of allocation used is unspecified, so I don't think
anyone can reasonably be hurt by this change (and it's good for
people who want to build the library with -fno-exceptions).

OK for trunk, thanks.
