When would you ever /need/ to compare pointers to different objects?
For almost all C programmers, the answer is "never".  Pretty much the
only example people ever give of needing such comparisons is to
implement memmove() efficiently - but you don't need to implement
memmove(), because it is already in the standard library.  (Standard
library implementations don't need to be portable, and can rely on
extensions or other compiler-specific features.)

Somebody has to write memmove() and they want to use C to do it.
