[BusyBox] Re: login buggy also in 1.00pre5

Hi!

I wounder why I see the busybox mailinglist in the CC-header but not
any of your answers really make it to the list. Therefore I'm keeping
the full quote.

I have the problem also when running login from a shell or
from getty (here it hangs forever). So I think the telnet daemon
does not make a difference here. BTW I use the utelnetd that is
included in the Axis developer kit, which I see got included now
in busybox, but the sources are a little different.

Is there a way to compile one busybox applet standalone so I could
run it with debug symbols under gdbserver? Because I've already
got gdbserver I would not have to mess with getting strace/ltrace
compiled.
