Busy Box [bug -fix]

Wed May 17 01:43:44 UTC 2006

Hi Bernhard,

It's nice to have  your comments.   I have tried on several machines, and
all gives me the same error. After I conduct the patch I sent to you
yesterday, busybox works fine for me.

The snapshot I used was on May 08th, 2006. below is the information you
requested.  The development platform is a freshly installed Fedora Core 5.

gcc: 4.1.0
target: at91rm9200ek
arm-linux-gcc: 3.4.2
uClibc: snapshot 08May'06

Please check the attachment for the .config files I used.  Please feel free
to ask for more information.
