searching for a BNF (for yacc) grammar of C++

Question

I found something similar here: Where can I find standard BNF or YACC grammar for C++ language?

But the download links don't work anymore, and I want to ask if somebody know where I can download it now?

Answer 1

C++ is not a context-free language and therefore cannot be accurately parsed using a parser like BNF or yacc. However, it is possible to parse a superset of the language with those tools, and then apply additional contextual processing to the parsed structure.

Looking here: http://www.parashift.com/c++-faq-lite/compiler-dependencies.html#faq-38.11, I found this: http://www.computing.surrey.ac.uk/research/dsrg/fog/CxxGrammar.y
