	cygwin         : ChangeLog spawn.cc 

Log message:
	* spawn.cc (system_call_cleanup): Rename from pthread_cleanup.  Extend
	functionality.
	(system_call_cleanup::system_call_cleanup): Set up signals like system()
	requires.  Unblock previously-blocked signal handling.
	(system_call_cleanup::~system_call_cleanup): Restore signal handling after
	system().
	(child_info_spawn::worker): Put signals on hold and use system_call_cleanup
	class to set and restore signals rather than doing it prior to to running the
	program.  Remove the ill-conceived pthread_cleanup stuff.
