Anything that is called "path" should be a list of directories, nopt a single file name (this is GNU, remember?). So try something like this: (setq find-function-source-path '("c:/projects/emacs/lisp/" "c:/projects/emacs/lisp/emacs-lisp/" "c:/projects/emacs/lisp/net/" ...)) (add more subdirectories instead of the ellipsis).
