This is related, I think: I cannot run the test suite:

  $ make file-notify-tests.log
  make[1]: Entering directory `/d/gnu/git/emacs/trunk/test/automated'
  Compiling file-notify-tests.el

  In toplevel form:
  file-notify-tests.el:40:1:Error: Too many arguments to `defclass'
  Makefile:62: recipe for target `file-notify-tests.elc' failed
  make[1]: *** [file-notify-tests.elc] Error 1
