[lkb] GNU clisp and generation

Hello!

I'm having some problems with generation in LKB, using the latest
06.03.05 version.
Running with GNU CLISP on FreeBSD.

Using TTY commands:
(do-parse-tty "Ola sover")
(do-generate-tty)

the result is:
Generating from parser edge 5
WARNING:
LOGIOR: NIL is not a INTEGER
No strings generated
NIL

This error does not appear on the latest Windows version (precompiled
with allegro) using exactly the same grammar. The system sometimes
complains about "LOGTEST: NIL is not a INTEGER" also.

I have little knowledge of LISP, so it would be nice if you could help
me here. Is this a compatibility issue?
