Useful, yes. Essential? Maybe yes, maybe no, depending on reorg.
And flow. It is information that's used in a lot of ways and I don't think
trying to figure out precisely the effect of having the wrong data is

There are two questions before us: (1) what to do for gcc 3.0, and
I'd like to just have all the routines in question support all the
forms that are in use now. We can clean it up later.
