The latest news about this version is probably that some Druids used it at

And this one is not supported either, I think.

This is only one problem with older version under C++; another is that the
C stack enlargement does not invoke the C++ copy constructors as it should.
Therefore, the proper thing is to use a C++ container.

There is a Bison beta that does just that:
    ftp://alpha.gnu.org/gnu/bison/  (bison-1.49x)
Try this one; compile with option -S c++.bison (or was it bison.c++?) or
something like that (to choose the right skeleton file.
