	Removed.
	* inet/rcmd.c: Remove __P.  Remove unused variables.
	(iruserfopen): Make first parameter const.
	(ruserok_sa): Return result of ruserok2_sa.
	(__checkhost_sa): Correctly iterate through results of getaddrinfo.
	* inet/rexec.c: Remove unused variables.  Other small cleanups.
	* inet/ruserpass.c: Remove __P.  Remove unused variables.
	(ruserpass): Check results of memory allocation.
	* include/netdb.h: Add prototype for ruserpass.
