A Common Lisp to C compiler by Heinz Knutzen, Ulrich Hoffman and Wolfgang Goerigk. CLiCC is meant to be used as a supplement to existing CLISP systems for generating portable applications. Target C code must be linked with the CLiCC run-time library to produce an executable. Version 0.6.2 conforms to a subset of Common Lisp and CLOS called CL_0 or CommonLisp_0 and based on CLtL1. It runs with Lucid Lisp, AKCL or CLISP. Work on CLtL2 and ANSI-CL conformance is in progress.
