The gcc maintainer (David O'Brien at the time) was unwilling to
support the burden of an external gcc patch which would need to be
re-integrated by him each time a new gcc version was imported.
Instead, we agreed that the best solution was to make a port that uses
this patch, which can be updated periodically as the SSP authors track
new gcc releases. Neither of us followed through on this though.
