For the original user, I would suggest checking column 7 in your
YY_INPUT() routine, and simply dropping the comments out (read
the next line instead)
To keep track of the column info in my flex scanner, I define the
flex macro YY_USER_ACTION to add the yyleng to my counter. This
gives the same effect as what you do above, but it does not have
to explictly appear in every code section.
