It is a generated file.  If you really think it is necessary, you need
to patch its source, i.e., contrib/flex/src/parse.y, and regen the file.

However, I don't see much sense in automatically adding BSD license in
every generated file in the first place.  In fact, I think it should not
appear on generated file at all.  It may say something along the line of
"generated by flex" instead but IANAL.
