No, the C++ skeleton I made is only published in the Bison-Patches list. A
long time ago Akim Demaille put his students to write a C++ skeleton file,
which is the one you got with the distribution. But, as I could not get it
working, I wrote my own. Right now, nobody is working on the C++ issue.

But you need only this skeleton file if you use a semantic type with
non-POD data members; otherwise the compiling the C output as C++ will
suffice. In particular, if you use the Bison %union feature, then you can
compile C as C++.
