Additionally, flex.1 says the following:

       main   directs  flex  to  provide a default main() program
              for the scanner, which simply calls yylex().   This
              option implies noyywrap (see below).

My sense is that Vern is correct: The right thing to do is to not use
%option main if you want yywrap() to be under your control.
