Should char_traits<char>::int_type be an int or unsigned long?

Actually the right place to look at is:

  // 21.1.4  char_traits specializations
  template<>
    struct char_traits<char>
    {
      typedef char              char_type;
      typedef unsigned int      int_type;
      typedef streampos         pos_type;
      typedef streamoff         off_type;
      typedef mbstate_t         state_type;

But it is broken as well.  The Standard says int_type is a typedef for
`int'.

V3 is wrong.  Thanks for the bug-report.
