	cygwin         : ChangeLog fork.cc sigproc.cc 

Log message:
	* fork.cc (fork): Honor error return from sig_send.  Don't continue with fork
	if we couldn't suspend signals.
	* sigproc.cc (sig_send): Set sigCONT event when we see __SIGNOHOLD.
	(wait_sig): Remove holding_signals.  Create pipe with a buffer which will
	theoretically cause blocking if there is nothing reading on the pipe.  Wait for
	sigCONT at end of loop when we have a __SIGHOLD.
