the bootstrap completed *without* errors!

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

Now Emacs trunk build OB... :)

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.

In more than six months, only one or two times Emacs, from trunk, closed
unexpectedly. Usually it is enough stable.

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.

perhaps... Cygwin "Creators" can help... ;-)

Just a note I forgot before...

I think the best way to start in fixing/clarifying this issue is to reproduce it with a simple test case in plain C.

In that case, Cygwin guys will know how to fix it or could clarify what is wrong etc.
