 * improve r12493 - use [http://pubs.opengroup.org/onlinepubs/009695399/functions/memmove.html memmove] instead of [http://pubs.opengroup.org/onlinepubs/009695399/functions/memcpy.html memcpy]
 * nor sure if it's really necessary in this case, but both the originally used [http://pubs.opengroup.org/onlinepubs/009695399/functions/bcopy.html bcopy] & [http://pubs.opengroup.org/onlinepubs/009695399/functions/memmove.html memmove] can deal with overlapping memory areas whereas the behaviour of [http://pubs.opengroup.org/onlinepubs/009695399/functions/memcpy.html memcpy] in this case is undefined.
