Thee warnings seem to be bogus.

"libbb/single_argv.c:13:17: warning: array subscript is above array bounds"

char* FAST_FUNC single_argv(char **argv)
{
        if (argv[1] && strcmp(argv[1], "--") == 0)
                argv++;
        if (!argv[1] || argv[2])
                bb_show_usage();
        return argv[1];
}

I don't see how gcc arrived to this conclusion.
