Geir Thomassen wrote, regarding networking/httpd.c line 1358

    Hello, I think the test for an unconfigured httpd is wrong in
    the CVS (busybox-unstable-20030620.tar.bz2)

    flg_deny_all is default 0

    Oops. You are right.

    Last patch rewroted to my new get_ularg() function for overcompensate size
    from this error found ;-)
