The arithmetic inserters are described in 31.7.6.3.2[ostream.inserters.arithmetic].Although the section starts with a listing of the inserters includingthe new ones:

operator<<(long long val );operator<<(unsigned long long val );

the text in paragraph 1, which describes the corresponding effectsof the inserters, depending on the actual type of val, does nothandle the typeslong long andunsigned long long.

[Alisdair: In addition to the (unsigned) long long problem, that whole paragraphmisses any reference to extended integral types supplied by theimplementation - one of the additions by core a couple of working papersback.]

Proposed resolution:

In 31.7.6.3.2[ostream.inserters.arithmetic]/1 change the third sentence
