Dear Wolfgang,
By the Way, another problem now. If I transfer UDP packets from my PC to my
board as "netperf -H 192.168.0.5 -t UDP_STREAM -l 30", a problem happens on
my ML403 board and ppc 405 as:

If I specify the time length shorter, e.g. -l 5, it will not happened.
This never happens when using TCP.
Can anyone tell me what's the reason and how to solve this? thanks for your
helping.

$ echo "ac_cv_func_setpgrp_void=yes" > config.cache
$ ./configure --host ppc CC=powerpc-405-linux-gnu-gcc --config-cache
