* memset: also update copyright yearsMike Frysinger2012-04-081-1/+1

* memset: fix define usage for shared libsMike Frysinger2012-04-071-1/+1
| | | | | | | The proper define to check "am I in a shared lib" is "SHARED", not "PIC". The two new memset_chk functions incorrectly depend on "PIC". Signed-off-by: Mike Frysinger <vapier@gentoo.org>
