I did a similar report on emacs-devel:

http://lists.gnu.org/archive/html/emacs-devel/2013-06/msg00333.html

Now I have discovered that trunk rev. 112858 build fine while rev. 
112859 fails as described. These are the changes that have broken the 
bootstrap on Cygwin:

 3        Chain glib's SIGCHLD handler from Emacs's (Bug#14474).
 4        * process.c (dummy_handler): New function.
 5        (lib_child_handler): New static var.
 6        (handle_child_signal): Invoke it.
 7        (catch_child_signal): If a library has set up a signal handler,
 8        save it into lib_child_handler.
 9        (init_process_emacs): If using glib and not on Windows, 
tickle glib's
 10        child-handling code so that it initializes its private 
SIGCHLD handler.
 11        * syssignal.h (SA_SIGINFO): Default to 0.
 12        * xterm.c (x_term_init): Remove D-bus hack that I installed 
on May
 13        31; it should no longer be needed now.
