This is what I get when I compile with your test:

Looks like it works perfect to me.  You are using Boost Trunk like I
stated in my first post in this thread, right?

You should still use this grammar though, it is the best:
        bk::generate(ostream_iterator<char>(cout),
                "Command line options not recognized:\n" <<
                ("  \"" << ba::string << '\"') % bk::eol
                ,vsTest);
And yes, I confirmed it compiles and runs as you want.
