I have ported Boehm's conservative GC to pthreads. It needs exactly the same
information that you cite in your message. I am going to make this port
freely available on our FTP server today, or within the next couple of days.
You might like to look at the sources there to see how I extracted this
information.
[I will post an announcement to this list when the port is available.]
Regards,
Ian
