{ far pointer arithmetic tests }
{ far pointer arithmetic should work only on the offset,
without changing the segment }
{ this test is the same as tfarptr3, but with different numbers, designed to
expose buggy far pointer arithmetic, where the int16 int is treated as a
signed int and is sign extended to 32-bit and then added to the far pointer
as a 32-bit int }
