Does Cygwin have a non-trivial definition of convert-standard-filename?
(If not, it needs one, but I'm not sure where to put it.  Any
suggestions?)

This fragment from files.el:make-auto-save-file-name:

            ;; Make sure auto-save file names don't contain characters
            ;; invalid for the underlying filesystem.
            (if (and (memq system-type '(ms-dos windows-nt))
                     ;; Don't modify remote (ange-ftp) filenames
                     (not (string-match "^/address@hidden:" result)))
                (convert-standard-filename result)

makes sure that invalid auto-save file names are never created on
DOS/Windows, but it doesn't catch Cygwin.

Make sure you search the archives of this list and of emacs-devel,
we had reports about Cygwin problems due to bugs in the Cygwin
runtime.  For example, see these messages:
