OK, from looking at that patch I guess that if your src/lex.cc file
has the lines

  case EOB_ACT_END_OF_FILE:
          {
          if ( octave_wrap( ) )
                  return 0;

instead of

  case EOB_ACT_END_OF_FILE:
          {
          if ( octave_wrap( ) )
                  return EOF;

then it looks like the version of flex that you used to generate
lex.cc is the one that has been modified with the bad patch.
