Hi
Do not write a new C++ parser; it will take a very very long time to get
right.
You certainly need necessarily all of the C++ grammar and a good C++
preprocessor too.
You should re-use an existing C++ parser, (g++ if you refuse to invest
in a good commercial offering).
If you really insist on writing a parser use an LALR grammar and my C++
grammar, which is the only yaccable implementation
(http://www.parashift.com/c++-faq/yaccable-grammar.html). Read chapter 4
of my thesis
