I think I see the problem.  Try replacing this line from
leim/Makefile.in:

	    --eval "(update-leim-list-file \".\" \"${srcdir}\")" ; \

with this:

	    --eval "(update-leim-list-file \".\" (reveal-filename \"${srcdir}\"))" ; \

and also add the following function to subr.el:

(defun reveal-filename (file)
  "Produce the real file name for FILE.

On systems other than MS-Windows, just returns FILE.
On MS-Windows, converts /d/foo/bar form of file names
passed by MSYS Make into d:/foo/bar that Emacs can grok.

This function is called from lisp/Makefile."
  (when (and (eq system-type 'windows-nt)
	     (string-match "\\`/[a-zA-Z]/" file))
    (setq file (concat (substring file 1 2) ":" (substring file 2))))
  file)
