The standard LR(1) state machine does not look deeper into the stack, but
the DR  does (I take it from the description given in the Bison lists).
Then just use say std::vector instead. The std::stack is just an adaptor
class.

Or it should be easy to merely require the use of an abstract class A,
which the user specifies. For example, the LR(1) algorithm would require A
to have A::push_back(), A::pop_back(), etc., and some other parser
algorithm may require extra class functions.
