[PATCH] work around bug in older bytecode verifiers

[Paolo Bonzini]

... but even not so old, as gcj 4.1.1 has this bug.

These disallow access to the private fields of an inner class, from the 
outer class.  In this case the inner class is the parse stack, the outer 
class is the Bison-generated parser.

However, we can make Stack's field public because user code doesn't have 
access to the instance of Stack used by parse().  I'll commit this as 
soon as the regression tests end.
