Another alternative is to replace

    if (! noninteractive || initialized)

by

    if (! noninteractive)

at least on Cygwin.  That allows the bootstrap to complete without 
errors.  Assuming this doesn't cause other problems, we wouldn't have to 
worry about reintroducing bugs into (interactive) Cygwin Emacs.
