I have a lot of C++ code in my .y file, and no problems. This is 1.875c 
- has this support been dropped since then?

But then, I can't immediately see why any C++ support is required, as 
long as you use the union/struct mechanism for passing data. My YYSTYPE 
is a struct which contains reference-counted classes. Maybe this is the 
confusion? Do you only need the C++ skeleton if your YYSTYPE is a real 
C++ class?

BTW, you don't even need Satya's 'extern "C"' declarations if you're 
using gcc; don't know about other compilers.
