   Knowledge of how many languages should the preprocessor stage have?   
      
      
   I think that all parts of a compiler front end should follow the   
   specific language rules. Just for maintenance purposes.   
      
   If universal generator tools for lexer or parser are used then the   
   specific language grammar is the input to these tools.
