[slime-devel] Spawning child process: invalid argument / Emacs on W2K + SBCL 0.9.12

Unfortunately I currently need to hack on a Win2K box. I don't think it's my choice of CL impl; tried Clisp & SBCL 0.9.12. I added the requisite four lines to .emacs (which my Emacs, v21.3 can definitely see), but I keep getting: Spawning child process: invalid argument when I M-x slime . I get a little something, a menu bar ' SLIME' addition, when I M-x slime-mode; but no REPL, etc. I spent sometime mining GMANE for an answer, but I only saw a partially similar unanswered question by Peter Siebel. I must be doing something fundamentally wrong. pfd
