 Generated Flex class name is yyFlexLexer by default. If we want to use more flex-generated
 classes we should name them differently. See scanner.l prefix option.

 Unfortunately the implementation relies on this trick with redefining class name
 with a preprocessor macro. See GNU Flex manual, "Generating C++ Scanners" section
