This updates the shipped file generated by flex to support the
explicit use of "---help---" and to emit warnings for unsupported
characters on top level statements.
As I could not find out which flex version was used to generate
the previous version, I used flex 2.5.35 from Ubuntu 14.04 - this
also leads to the big number of changed lines in this patch.
