ABCL doesn't yet know about the long form of defsetf, used in xref.lisp. Do clispers (the only users of xref in slime) have anything against the patch below? It seems to work in clisp, but I'm no defsetf expert, so I'd rather ask before committing.
Is it hard to implement defsetf? I've heard a good principle for Lisp implementors is to take these incompatibilities as a motivation to extend their Lisp rather than contorting programs to use CL subsets. :-)
