Thanks again.  I missed those because they don't use
makeStringConst().  Looking again, it turns out "many productions" is
more like 15.

That's a bigger number, certainly, but it's still manageable.  It
wouldn't be hard to convert them to generate a const-in-a-cast.  In
fact with the addition of a makeCastStringConst(), I think the code
saving from A_Const->typename would be cancelled out.

If the only reason for keeping A_Const->typename around is the alleged
code saving (as indicated by the code comments), my offer to do away
with it is still on the table.
