I think that I have done all I can to libgc. I cannot do the cthread stuff within the library, but there is pthread stuff there, for when we get pthreads. Sorry for the long delay, if I am not too late, please let me know if you are interested in this work.
Have built bigloo. This has a built in libgc, so it helped with the testing. The results are identical with the Hurd or Linux. http://kaolin.unice.fr/bigloo/bigloo.html The disadvantage is that it does not install the libgc headers and that it not a Debian package. I must learn more about this package now that it runs on the Hurd. I can post a patch to bigloo for the Hurd if you want. I am now going to transfer the libgc stuff into a new directory. I can either overwrite the source of the old Debian libgc package or I can copy the debian/rules to the new. I want to build a deb package that includes the libgc archive and headers. Chris
