[movitz-cvs] CVS update: movitz/losp/los0-gc.lisp
by Frode Vatvedt Fjeld 15 Jul '04

15 Jul '04

Update of /project/movitz/cvsroot/movitz/losp In directory common-lisp.net:/tmp/cvs-serv30689 Modified Files: los0-gc.lisp Log Message: Some pieces of los0-gc were (because of laziness) set up as part of the default system. This factors out los0-gc from the default system properly. Also, changed the signature and implementation of install-los0-consing a bit: It now takes the run-time-context object to install onto as an explicit (keyword) argument.
