	cygwin         : ChangeLog errno.cc fhandler.cc fhandler.h 
	                 fhandler_tty.cc 

Log message:
	* errno.cc (errmap): Add mapping for ERROR_IO_INCOMPLETE.
	* fhandler.cc (fhandler_base::fcntl): Fix comment.
	(fhandler_base::wait_overlapped): Accept an optional len parameter.  Use the
	len parameter when WriteFile fails with ERROR_IO_PENDING.  Make debug output
	less alarming.
	(fhandler_base::write_overlapped): Pass len to wait_overlapped.
	* fhandler.h (fhandler_base::wait_overlapped): Add an optional argument
	denoting the number of characters intended to be written.
	* fhandler_tty.cc (fhandler_pty_master::close): Don't close archetype handles
	when cygwin is still initializing since the handles aren't actually opened at
	that point.
