There are versions of flex and bison that have been rewritten to be more 
C++-ish that are appropriately named flex++ and bison++. They are similar in 
capability to flex and bison, but instead generate C++ classes. The source is 
available here:

I've not used the tools myself, but a colleague used them to solve the 
problem with the globals.
