Comment (by marshall):

 But I do believe that it has to be a "signed integer type"

 See [iterator.requirements.general]/p1; the last sentence:

     For every iterator type X for which equality is defined, there is a
 corresponding signed integer type called the difference type of the
 iterator.

 See also [basic.fundamental]/p2, which says:

     There are five standard signed integer types : “signed char”, “short
 int”, “int”, “long int”, and “long long int”.
