 Message        <Context> "<expression>", a 64-bit integer, is being
                cast to a 32-bit integer.  The cast might result in
                data loss.

 Description    On many platforms long integers are the same size as
                integers.  On this platform long integers are
                64-bits.  This cast could indicate a potential
                porting problem.

 User Action    Verify that no unexpected data can be lost by the
                cast.
