Hi,
I'm using extended loop macro syntax (as stated in Guy L. Steele "common
lisp", second edition, section 26.3 p. 710)
(loop while (null res) do
(print max_depth)
(setq res (dfs initial_state final_state 1 max_depth))
(setq max_depth (+ max_depth 1)))
This piece of code runs correctly on CMU CL and on CLISP, but produce
the following error at GCL:
>Compiling stone-puzzle.lisp.
; (DEFUN IDS ...) is being compiled.
;; The variable WHILE is undefined.
;; The compiler will assume this variable is a global.
;; The variable DO is undefined.
;; The compiler will assume this variable is a global.
End of Pass 1.
End of Pass 2.
OPTIMIZE levels: Safety=0 (No runtime error checking), Space=0, Speed=3
Finished compiling stone-puzzle.lisp.
IMHO, GCL doesn't include extended loop macro.
Is it true?
Are there any more parts of CL that GCL doesn't include?

I think GCL implements most of CLtL1, and not much of the stuff that was
added in CLtL2.
There are public versions of the LOOP macro that you can download; check
the FAQ for pointers.

Not only that, but GCL stubbornly refuses to include in their standard
build, key CLtL2 additions which *are* available "out there". LOOP
being one of them as Barry points out. The other sore point is
DEFPACKAGE.
These are the problems that made me dump GCL in favor of CMUCL.
