Doesn't CLisp make exceptions if your project uses a compatibility layer?

This copyright does *not* cover user programs that run in CLISP and
third-party packages not part of CLISP, if
a) They only reference external symbols in CLISP's public packages
that define API also provided by many other Common Lisp implementations
(namely the packages COMMON-LISP, COMMON-LISP-USER, KEYWORD, CLOS,
GRAY, EXT), i.e. if they don't rely on CLISP internals and would as
well run in any other Common Lisp implementation. Or
b) They only reference external symbols in CLISP's public packages
that define API also provided by many other Common Lisp implementations
(namely the packages COMMON-LISP, COMMON-LISP-USER, KEYWORD, CLOS,
GRAY, EXT) and some external, not CLISP specific, symbols in
third-party packages that are released with source code under a
GPL compatible license and that run in a great number of Common Lisp
implementations, i.e. if they rely on CLISP internals only to the
extent needed for gaining some functionality also available in a
great number of Common Lisp implementations.
Such user programs are not covered by the term "derived work" used in
the GNU GPL. Neither is their compiled code, i.e. the result of compiling
them by use of the function COMPILE-FILE. We refer to such user programs
as "independent work".

A compatibility layer(like uffi or cffi) would be relying "on CLISP
internals only to the extent needed for gaining some functionality
also available in a great number of Common Lisp implementations",
would it not?
