I guess I would suggest we kind of stay out of the grammar at the
moment.  I really do have a partly done new recursive-descent parser,
which can do better error recover; it's waiting for the time and money
required to finish it.  I would expect that sometime within the next
few months, those resources will become available.

The bison grammar is quite fragile; sometimes even reasonable changes
cause things to break in odd ways.  I'm not commenting on your patch,
just on the general case. 

So, I have nothing to say about your patch; just a general
encouragement not to try to push the square LALR(1) into the round
hole of great parser for C++. :-)
