OK, thanks, as trunk bzr 113206 I installed a change
to skip the gnulib tickling on Cygwin.

Although this should fix the bootstrap failure, I expect that
this reintroduces a bug into Cygwin Emacs, namely,
Emacs can sometimes lose track of subprocesses and/or kill off
unrelated processes; see Bug#12980 and Bug#8855.
Fixing this will require someone with access to Cygwin
and knowledge of how to debug threads under Cygwin,
neither of which I have.  Since the issue appears only
under Cygwin it could well be a Cygwin bug rather than an
Emacs or glib bug.

Another alternative is to replace

    if (! noninteractive || initialized)


    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.
