That the Emacs source directory is checked-out from arch -- e.g., it has
an {arch} subdirectory.  I could be totally wrong about the necessary
preconditions, of course. :-)

It also happens that I build in a separate build-directory, which might
affect things (my build dir = /home/m/miles/build/emacs/devo, source dir
= /srv/data/home/m/miles/src/emacs/devo).

Hmmm, also I wonder if the presence of things like {arch}/,,inode-sigs
affects things -- I notice that vc-arch.el tends to load files from
there when you visit a file checked out from arch.

   $ ls {arch}/,,inode-sigs

Any ideas on how to debug it?  I can reproduce the error in an
interactive emacs, by doing:

   $ cd /home/m/miles/build/emacs/devo/lisp
   $ wins='/home/m/miles/src/emacs/devo/lisp/. 
   $ ../src/bootstrap-emacs  --no-site-file --multibyte -l autoload --eval 
'(setq generated-autoload-file 
"/home/m/miles/src/emacs/devo/lisp/loaddefs.el")' -f batch-update-autoloads 

But I'm not sure how to get a lisp stack backtrace -- I tried adding the
command-line option --eval '(setq debug-on-error t) but it seems to have
no effect.  If I subsequently try to manually invoke the same command
inside the resulting emacs session (which is still running) it succeeds!
