Found the problem. For some reason gcl generates incorrect C code for
the following:
(defun max0 (x y &rest z)
(declare (integer x y))
(apply #'max x y z))
It doesn't like the declaration, so commenting it out allows gcl to
compile f2cl-lib.lisp. Hurray!
However, I now get warnings about INT being in the Lisp package and
not defined when compiling ifix, idfix, aint, etc. First, why is INT
in the Lisp package, and, second, why does gcl warn about this? Seems
to work ok, though.

I see that destructuring-bind is now in the LISP package, but it's not
exported so I've hacked around this by doing an import. No more
errors when compiling f2cl-lib.
Note, however, there are compiler warnings about do-arg-error-count
not being defined. Probably need to borrow the code from CMUCL or
create your own equivalent.

Camm's latest rev for this works beautifully. Although, I think it
ought to work the same was as floor/ceiling does instead of consing up
the result just so some lisp code and return it as tow values. I'll see
if I can't come up with a patch to implement this.
With these changes, I've successfully built maxima with gcl. Hurray!
