Now wait...  I'm sure I SUPed those gcc changes once, if only to
stroke my ego 8-)  Maybe I just got a notification in source-changes,
and it went to a different branch?  Maybe I have no ability to
remember past events?  Maybe...

Perhaps someone should fix the source tree, and/or ping Mr. Kenner.

Cool!  I ran into a few hitches (as explained in a previous message) that
I hope you don't...  I *think* I thought about merging mul and add, but
figured other things I couldn't solve were more important and easier.
(Maybe I should have tried just a little harder...)
