No, CLISP compiles to bytecode only, not to C.

No.

AKCL is a Common Lisp system that compiles to C, then uses the machine's
C compiler to compile to machine code, and AKCL can load such machine code
mudules into the running image.

CLiCC on the other hand can build stand-alone executables from Common Lisp
programs, again using the machine's C compiler.


The CLiCC README file:

    CLiCC is a Common Lisp to C Compiler.  It generates C-executables 
    from Common Lisp application programs. CLiCC is not a Common Lisp 
    system.  Hence it does  not  include any  program  development or 
    debugging support.  CLiCC is intended to  be used as an  addon to 
    existing Common Lisp systems for generating portable applications.
    
    CLiCC supports a subset of Common Lisp + CLOS, which we call CL_0
    (CommonLisp_0).  CL_0  is a strict and very large  subset of full
    Common Lisp + CLOS, without  (EVAL ...) and friends.  At present,
    CL_0 is based on CLtL1,  but  we  are  working towards  CLtL2 and
    ANSI-CL.
    
    The target language is a subset of C. CLiCC is adaptable to gene-
    rate ANSI-C or K&R-C by using a compiler option.  The generated C 
    code is compilable using  a conventional C compiler on the target 
    machine,  and must be  linked with the  CLiCC runtime library  in
    order to generate executables.

CLiCC runs in CLISP without any modification, but you need at least 8 MB RAM.
