For an example of a reentrant flex/bison parser, see
http://users.erols.com/blilly/mparse/index.html

Basically, you need to tell flex to generate a header file with the
macro definitions and function declarations, then you need to massage
it (see make.file in the package above) e.g. using sed to make it
play nicely with bison and gcc. Finally, you need to have the parser
#include the massaged header file at an appropriate point.
