Richard,
This is not quite correct (or, at best, is ambiguous). From my favorite C
manual ("C: A Reference Manual", by Harbison and Steele, 4th edition):
"The C language does not specify the range of integers that the integral types
will represent, except to say that type 'int' may not be smaller than 'short'
and 'long' may not be smaller than 'int'. Many implementations represent
characters in 8 bits, type 'short' in 16 bits, and type 'long' in 32 bits, with
type 'int' using either 16 or 32 bits depending on the implementation. ISO C
requires implementations to use at least these widths."
So, the sizes can be larger in any compliant compiler, and may be smaller in a
non-compliant (pre-ISO) compiler.

"int" is a tricky thing in C.
"long int" is a guaranteed 4-byte value.
"short int" is a guaranteed 2-byte value.
But "int" (unadorned by modifier) is the value that is most "natural" to the
processor.
