That one doesn't compile for me. On line 402:

I get
no instance of overloaded function "boost::spirit::qi::parse" matches the argument list
You are running Boost Trunk? Compiles fine here in MSVC, and I last synced to trunk less then a week ago.
The problem is that parse takes its first argument by reference, and va.begin() is a temporary. If I take a copy of va.begin() and pass that it works fine. I don't see how this compiled in MSVC (does string::begin() return a non-const reference?), but anyway.
