Argument mapping issue of awk

[Ondrej Zima]

Hi all,
I have one big problem using busybox with uClibc in embedded device with
mipsel architecture.
A creating some sh scripts where most used application is awk. I create
some scripts and they didn't works.

See following simple example:

echo "a b c" | awk '{ print "a="$1",b="$2",c="$3; }'

If I use it in my desktop Linux (Debian x86_64) the output is (as expected)

ondra at keltek:~$ echo "a b c" | awk '{ print "a="$1",b="$2",c="$3; }'
a=a,b=b,c=c

But if I make the same on my busybox device, the output is wrong

default at Venus:~# echo "a b c" | awk '{ print "a="$1",b="$2",c="$3; }'
a=,b=,c=

The mapping of arguments didn't works. And I don't know, what is wrong.
The uClibc or busybox or something other?
