+       char *role = NULL;
+       char *range = NULL;
+       char *user = NULL;
+       char *type = NULL;
+       char *context = NULL;
+       unsigned int opts;

+       selinux_or_die();
+
+       opts = getopt32(argc, argv, "r:t:u:l:ch", &role, &type, &user, &range);
+
+       if (!role && !type && !user && !range) {
+               if (optind >= argc)
+                       bb_error_msg_and_die("must specify -c, -t, -u, -l, -r, or context");
+               context = argv[optind++];
+       }

Testing if(!(opt & MASK_role_type_user_range)) will result in smaller code.
