For lending structure to data, when using clisp or gcl (free Lisp on
Unix), is CLOS well supported, or should I stick with the older
DEFSTRUCT. I would prefer to use CLOS, but if CLOS on clisp and/or
gcl is too buggy, please let me know.
I'm not looking for fancy features, just the best way to avoid nested
car (first) and cdr (rest) all over the place...

I don't know about clisp. kcl/gcl uses pcl as its clos, and it
can be kind of slow. In particular, it compiles some things on
the fly, and in kcl/gcl that means running the C compiler.
For many purposes, defstruct is still a good solution. You should
even be able to write methods that are specialized on structure
classes.
