{\bf Caveat:} On machines where C's \code{long int} type has more than
-32 bits (such as the DEC Alpha or the HP Precision Architecture), it
+32 bits (such as the DEC Alpha), it
is possible to create plain Python integers that are longer than 32
bits. Since the current \code{marshal} module uses 32 bits to
transfer plain Python integers, such values are silently truncated.
