Sometimes the bootstrap hangs:

[...]
make[3]: ingresso nella directory "work/emacs/Work/lisp"
Compiling work/emacs/src/../lisp/emacs-lisp/map-ynp.el
make[3]: uscita dalla directory "work/emacs/Work/lisp"
make[3]: ingresso nella directory "work/emacs/Work/lisp"
Compiling work/emacs/src/../lisp/cus-start.el
WAIT WAIT WAIT...
IT HANGS

and I cannot break it with CTRL-C. To kill the "bootstrap-emacs" process 
I need to kill it with Windows task manager. The Cygwin "kill -9..." 
command doesn't help... it helps only to kill some "make" processes...
