The bugs I had in mind were the omission of ",u". I guess the testing
was successful even if that was wrong. OK, I am willing to commit that
thing, I just had understood that you were going to test it once you
had your coco running again.

The fixes for the precomp misspelling and more have already been
pushed to the repo. Yes, precomp is disabled by default anyway.

The remaining part of that patch cluster (and what I meant by
unconfirmed changes) is the delay time in FDCDelay. The comments says
minimum 58 us but the current and suggested values make for much more.
I don't know how often this routine is called and if the extra delay
causes any performance drop.
