        Frankly, I wasn’t even able to build Emacs as of 8dfff871bdf0
        (2015-03-18 14:49:55Z), although the error for me is different
        (MIMEd.  Please note that I do not bootstrap – I /always/ build
        in a freshly created build directory; lndir-ed.)  Going two
        commits back (to fd93edbb1cab) resolved the issue.
