  Right, works nicely.  Also I discovered about "make install.modules" in the
meantime, which helps, and now it just works:

$ zsh --login

(admin AT ubik)[1] ~
$ echo "Hello world from ZSH"
Hello world from ZSH

(admin AT ubik)[2] ~
$ exit

$ echo $?
0

  So, what I did was not suitable for upstream, but I'll leave you to work
that one out with them.  I ...

a) Deleted these lines from configure.ac and regnerated configure:

b)  Modified the build script to enable auto import.

  Everything built and runs ok, and the testsuite reports:
