specified. When both are specified, the bulk of the glue code is
generated using the 32-bit machine description, but structs are
laid out twice and the base class delegates between the 32-bit

which can access both 32-bit and 64-bit versions of the data
structures to be included in the same jar file. <P>
It is up to the end user to provide the appropriate opaque
definitions to ensure that types of varying size (longs and
pointers in particular) are exposed to Java in such a way that
changing the machine description does not cause different shared
glue code to be generated for the 32- and 64-bit ports.
