Summary:
In Microsoft C versions 5.1, 6.0, 6.0a, 6.0ax, and C/C++ version 7.0,
when comparing far pointers with the <, >, <=, or >= operators, the
two pointers must be in the same segment. The equality operator (==)
tests both segment and offset to prevent two pointers that have the
same offset, but different segments, from being considered equal.
The <, >, <=, and >= operators assume that the pointers share the same
segment because according to ANSI, pointers can only be compared for
precedence if they point to the same object. In a segmented
architecture such as Intel's, two pointers to the same object must
share the same segment value, unless the pointers are declared to
point to a huge object, in which case the pointers are handled using
32-bit arithmetic.
