Yes, I'm not proposing that we implement them all at once, even if we
could find a list.  I was more interested in seeing whether there was
a uniform naming scheme and about how many there are.

I suppose the first thing to do is eliminate all the warn_* built-in
variables in favor of controlling warnings with warning [on|off] ID.
