.RS 4
For any given actual character type, this definition is probably wrong\&. (Most of the member functions are likely to be right, but the int_type and state_type typedefs, and the eof() member function, are likely to be wrong\&.) The reason this class exists is so users can specialize it\&. Classes in namespace std may not be specialized for fundamental types, but classes in namespace __gnu_cxx may be\&.
