The MPS GC is a commercial quality garbage collector that runs on Windows, FreeBSD, Linux and Mac OS X in both 32 and 64 bit configurations.

(For those who are interested in it for open source work, they're happy to talk about the licensing. They've been very generous with us for http://opendylan.org/ http://opendylan.org/ for example.)
