There is nothing to correct, because nothing is wrong.  ANSI C does not put
limitations on the sizes of types other than that sizeof char <= sizeof short
<= sizeof int <= sizeof long.  (Actually, there _are_ actually some further
limitations, but they don't go to the level of specifying the byte-width of
these types.)

The solution is to use the type on the platform and compiler that is useful to
you.  In DJGPP (and most Unix systems), a short takes up two bytes.  In fact, a
short is two bytes on most DOS compilers that I'm familiar with, as well.

Also, an unsigned X is always the same size as a signed X (where X is one of
the above fundamental data types).
