That is not actually in the standard GCC; it is in a forked GCC that
OpenBSD chooses to ship.
We (Immunix) are in the process of trying to make StackGuard (the
original) meet all of the criteria required for acceptance into GCC. At
the GCC Summit <http://www.gccsummit.org/2003/> in May, we presented a
StackGuard talk
<http://www.gccsummit.org/2003/view_abstract.php?talk=31> on that topic.
