Ok, I overlooked this part when I first read the mail, so I
manually made the change to put the fdtoiocb function into
its own file (since the patch didn't apply). Please take
a look. I did some sanity checks but nothing more yet.

I also removed the "initsp" constructor in crt0.s. I don't
remember why I turned the sp initialization into a
constructor, maybe some kind of mental derangement...
