Rick,

Try to use flex with ``-l'' option, from flex(1):

       -l     turns  on  maximum  compatibility with the original
              AT&T lex implementation.  Note that this  does  not
              mean  full compatibility.  Use of this option costs
              a considerable amount of performance, and it cannot
              be  used  with the -+, -f, -F, -Cf, or -CF options.
              For details on the compatibilities it provides, see
              the  section "Incompatibilities With Lex And POSIX"
              below.   This  option  also  results  in  the  name
              YY_FLEX_LEX_COMPAT being #define'd in the generated
              scanner.
