I stumbled over this recently as well.  And I also think that the
warning is very unhelpful.  "should/not/be/needed.h" is marginally
better, I'd appreciate a comment in the source explaining the likely
issue(s) though.

This provides a clue:
<http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/8709/focus=8711>

For me (and in the case of the coreutils package), the following works
to fix the issue:
  cd $top_builddir
  make clean            # if this does not remove lib/wctype.h,
                        # then remove it manually.
  find . -name .deps | xargs rm -rf
  ./config.status       # to regenerate the depfiles
  make

Hmm, if wctype.h is still built then there is another bug as well.
But I cannot reproduce your issues (with CVS texinfo and gnulib) on
Debian GNU/Linux.

Cheers, and a happy New Year,
