First, we've checked in the original source file as a separate file, I

... since you can refer to comments in the original source file IIRC.
Aha! Yes, I see. I've made that change.
Second, I think we've edited the compilation directory in the .S file,
and maybe other little details as well (I had to edit the files to avoid
'main' for some reason I cannot remember):

Ha ha. At least I didn't give away the farm! Alas, it isn't obvious to
me why 'main' would cause problems -- several .S files contain
references to that still.
I'm attaching the latest revision of this.
