Sorry, but I couldn't really follow what he wrote.  My guess is that
he was writing about his own C++ template file, which is a different

The C++ code that is generated by Bison 2.0 does not use "default:"
here, and his remarks about Bison using "default:" to implement $$ =
$1 do not seem to apply to the templates shipped with Bison 2.0.

Perhaps in some later version of the template we'll use "default:"
along the lines that he suggests; at that point, of course we'll have
to remove the "default:break;" that I just added.  But in the meantime
I don't see how the "default:break;" could hurt, regardless of whether
we're using C or C++.
