This is what the Bison generated parser normally does, passing  
through the input tokens fed to it each once.

The normal thing is to let the lexer (say generated by Flex) do such  
exclusions. It is common to do this with comments. These are then not  
fed to the parser at all, or perhaps as a single token of some post- 
processing is needed.
