C90 also has:

6.1.2.5 Types
    There are four signed integer types,
    designated as signed char, short int, int, and long int.

    For each of the signed integer types,
    there is a corresponding (but different) 
    unsigned integer type 
    (designated with the keyword unsigned) 
    that uses the same amount of storage 
    (including sign information) 
    and has the same alignment requirements.

    The type char, the signed and unsigned integer types, 
    and the enumerated types are collectively called integral types.

In C99, 
    6.2.5 Types
    17 The type char, the signed and unsigned integer types,
       and the enumerated types are collectively called integer types.
