Ok, so you want to keep using the internal "index" to indicate the
array position in the register cache. I _did_ specifically ask
to use defines for index values in this case. You did not explain
why you ignored this. So now you'll have to explain 1) why you
ignored my request and 2) why you want to keep the code as is.

And, _please_, add a To: recipient to your patches. I am getting
tired having to handle the fallout.
