The -fbounded-pointers and -fbounds-check options
were introduced by Greg McGary
(See http://gcc.gnu.org/projects/bp/main.html );
I have taken over that work as the Secure Pointers
Project, at John Gilmore's request,
but it is certainly not ready for prime time,
as I'm still fighting glibc wars at present, to the tune
of about 100 outstanding "make check" errors, which I suspect
are largely due to problems with recent improvements to
locale support in glibc.

I'd suggest removing the options from GCC 3.0.
Greg's and John's opinions should drive this decision.
