Does it?  I thought it was already changed!

This approach has several problems, all related to the fact that
bison.simple is independent from the parser file:

- it may not exist
- it may not be at the same location
- it may belong to a different version of Bison (worst case IMO).

I, for one, have always had problems with this `feature'.  Flex does
what 1.5x does, and in practice, it is much more convenient.  In
particular because you may have errors due to yourself which trigger
problems in the bison.simple section.  A bad YYSTYPE is an example.
