//  If you've used another iterator type than std::string::iterator, you have to
//  instantiate the new_lexer_gen<> template for this iterator type too.
//  The reason is, that the library internally uses the new_lexer_gen<> 
//  template with a std::string::iterator. 
//
//  This is moved into a separate compilation unit to decouple the compilation
//  of the C++ lexer from the compilation of the other modules, which helps to 
//  reduce compilation time.
//
//  The template parameter(s) supplied should be identical to the first 
//  parameter supplied while instantiating the boost::wave::context<> template 
//  (see the file cpp.cpp).
