I am unsure how to address the issue other than raising a PR. Being unable to bootstrap, certainly seems to be a blocking problem. Breaking the tree (and it seems that this issues has been known for a couple of weeks) and turning a blind eye seems to be rather unfriendly to other cwcontributors. PS: The description of --enable-maintainer-mode does not state that -Werror is added to the options. Why have an option that "regenerate[s] the Autoconf and Automake output files" if it cannot not be used?
