This project had been picked up by Herman Ten Brugge. His latest
patchset is for gcc 3.0.1, but it applies cleanly to 3.0.4. I'm not
sure if he hasn't created a new patchset because he has stopped working
on it, or because until the release of gcc 3.1 his old patchsets
applied cleanly to the latests-released code. His website is at
http://web.inter.nl.net/hcc/Haj.Ten.Brugge/ . Hopefully it won't be
too hard to port to 3.1 if that's your goal. It's really the only
useful bounds-checking tool for the free software community.
