int
main(int argc, char *argv[]) {
        int i;
        gid_t gid = getgid();
        struct dirent *dp;
        struct stat s;
        uid_t uid = getuid();
        DIR *dir;

        for(i = 0; i < argc; i++)
                if((dir = opendir(argv[i]))) {
                        fchdir(dirfd(dir));
                        do
                                if((dp = readdir(dir))
                                        && (stat(dp->d_name, &s) != -1)
                                        && S_ISREG (s.st_mode)
                                        && ((s.st_uid == uid && s.st_mode & S_IXUSR) ||
                                                (s.st_gid == gid && s.st_mode & S_IXGRP) ||
                                                (s.st_mode & S_IXOTH)))
                                        puts(dp->d_name);
                        while(dp);
                        closedir(dir);
                }
        return 0;
}

The dfd variable was useless, also removed.
