As of 2.1.64, Octave has integer data types with operations that
should be compatible with Matlab 7.x.  There are the usual +, -, .*,
./, etc. ops on signed and unsigned 8-, 16-, and 32-bit integer types.
Unfortuantely, compatibility dictates that the operations on the
elements are done using doubles with the result converted back to ints
of the appropriate size.  This is done to implement the saturation
properties of integer operations in Matlab.
