Well, the reason I ask is because if there is a chance that the cpp has to
be regenerated, and if, thus, developers are expected to have the tool (flex)
as part of their development environment, I can't see any reason to keep the cpp
in the repository. (The only reason would have been not to require users to
have flex, but that contradicts the previous case.)

Thanks,
