	* configure.ac: Added test for broken CMSG_FIRSTHDR macro
	  (relevant for Solaris 8 and unpatched Solaris 9, don't know
	  whether other platforms are affected).
	* zebra.h: Define ZCMSG_FIRSTHDR appropriately based on whether
	  config.h indicates HAVE_BROKEN_CMSG_FIRSTHDR (as determined
	  by the configure test program).
	* sockopt.c: (getsockopt_cmsg_data) Use ZCMSG_FIRSTHDR instead
	  of CMSG_FIRSTHDR.
	* rtadv.c: (rtadv_recv_packet,rtadv_send_packet) Use ZCMSG_FIRSTHDR
	  instead of CMSG_FIRSTHDR.
	* ripd.c: (rip_recvmsg) Use ZCMSG_FIRSTHDR instead of CMSG_FIRSTHDR.
	* ripngd.c: (ripng_recv_packet) Use ZCMSG_FIRSTHDR instead of
	  CMSG_FIRSTHDR.
