--- Comment #8 from Thomas Faller <tfaller1 at gmx.de> ---
printf is not the problem. Due to gcc optimizations printf 
is optimized to a puts -> \n will be removed.

If I use the switch -fno-builtin-printf the whole line (including \n) is
printed.


The problem that nothing is printed should be a fwrite (called by puts) issue.
