 Message        <Context> "<expression>", a pointer to a 64-bit
                integer, is being cast to a pointer to a 32-bit
                integer.  This may lead to unintended results.

 Description    On many platforms long integers are the same size as
                integers, and casting a pointer to long int to a
                pointer to int is not a problem.  On this platform
                long integers are 64-bits.  This cast could indicate
                a potential porting problem.

 User Action    Verify that this is the intended behavior.
