	cygwin         : ChangeLog sigproc.cc 

Log message:
	* sigproc.cc (pending_signals::retry): Declare new element.
	(pending_signals::pending): Force an additional loop through wait_sig by
	setting retry whenever this function is called.
	(sig_send): Reorganize to wait for SIGHOLD at bottom.  Always add signal to
	pending queue and work on whole queue rather than just the one signal.  Loop
	when sigq.retry is set.  Fix long-broken check for SIGCHLD after queued
	signals.
