* data/lalr1.java (Stack): Work around old verifiers that disallow
access to the private fields of an inner class, from the outer class.
We can make Stack's fields public because user code doesn't have access
to the instance of Stack used by parse().
* data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
Complain if the value does not match empty, "true" or "false".
* data/c++.m4: Adjust default definitions of %define variables.
* data/java.m4: Adjust default definitions of %define variables.
* doc/bison.texinfo (Decl Summary): Adjust the %define entry according
to above behavior.
* tests/input.at (Boolean %define variables): Test new behavior.
* NEWS: Mention java.
* TODO: Remove things that are done.

C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
under Other Languages.

b4_location_initial_line, p4_parse_param, b4_ints_in, b4_flag_if,
b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,
