There is the macro YY_DECL_VARIABLES; if you define it in the header,
instead of in bison.simple, you probably can skip the double classes. --
One problem though is that the macro YYPURE that would be needed seems to
written into the .tab.cc file. So it would need some tweaking of the Bison
sources.
