It doesn't change the fact that glibc changed behavior on some CPUs
(which is also going to make tracking down memcpy bugs highly
irritating, since the behavior will be different depending on the CPU).
Any normal person writing code is going to write a memcpy that copies
up, whether a simple C loop or optimized assembly, so I really doubt
you'll find lots of architectures that are widely used in the Unix world
where people use the memcpy routine in the standard C library that does
