Yes. I'm using newlib's printf and my cpu is
completely new one 
which is still under development. 

And I'm using
binutils-2.9.1
gcc-2.95.2
newlib-1.8.2
gdb-4.18.

I included <stdio.h> in my file. But it prints wrong.

So I guess the problem results from variable argument
things. 
What source can I start from? Can you give me a
pointer?
Thank you.
