Hi,

Today has been one dumb mistake after another. I apologize.
I'll do it properly shall I:

The above was run as root.
I iterate again, this binary was cross compiled with g++, and has
proven to work when copied onto an linux i386 machine. This was all
done by my friend who uses linux. He tells me he used the -m32 switch
of g++ to do so.
I hope this is all the information this time.
