Apparently, the way it is implemented in Bison 2.3 interacts badly
with preprocessor tricks done in sqlbison.y, while it works well for
the implementation in Bison 2.4 and 2.5.
Concretely, the overall problem is that Bison 2.3 puts much (more) of
sqlbison.y in sqlbison.hxx, which is #included in sqlflex.l. This
makes conflicts / pollutes the namespace. There were two compile-time
errors:
1) aEmptyString defined twice. I renamed the one of sqlflex.l
