PTRMISMATCH1

Message        <Context> the referenced type of the pointer value
               "<expression>" is "<type>", which is not compatible
               with "<target type>" because they differ by
               signed/unsigned attribute.

Description    In a pointer assignment, the type pointed to by the
               source pointer is different than the type pointed to
               by the destination pointer.  In this case the types
               differ because the signed/unsigned type attributes
               are different.

User Action    Correct the assignment to use compatible types.  This
               can be done by inserting a cast operand.
