	* sockopt.c (getsockopt_ipv4_ifindex): Document calling
	convention.  Beef up comments.  Handle the case where the cmsghdr
	has a zero controllen, or more specifically when the wanted option
	is not present.  This is needed for Solaris 8, and in general for
	any platform for which configure finds a method and it can fail.
	Mark some changes with XXX to be cleaned up post 0.98.
