intstr() -- Creates a string consisting of the raw bits in the low
order "size" bytes of integer i.

This procedure is normally used for processing of binary data
to be written to a file.

Note that if large integers are supported, this procedure still
will not work for integers larger than the implementation defined
word size due to the shifting in of zero-bits from the left in the
right shift operation.
