Thanks for the ping!

I have prepared some tweaks to the patch (see below).
Also, I have some doubts.  The prototype shows that it has no arguments
(void), but the text said that arguments, if any, are arch-specific.
Does any arch have arguments?  Should we use a variadic prototype (...)?

Please add the changes proposed below to your patch, tweak anything if
you consider it appropriate) and send it as v10.

Have a lovely day!
Alex
