Log Message:
Update to 2.6.4:

* Noteworthy changes in release 2.6.4 (2012-10-23) [stable]

  Bison 2.6.3's --version was incorrect.  This release fixes this issue.

* Noteworthy changes in release 2.6.3 (2012-10-22) [stable]

** Bug fixes

  Bugs and portability issues in the test suite have been fixed.

  Some errors in translations have been addressed, and --help now directs
  users to the appropriate place to report them.

  Stray Info files shipped by accident are removed.

  Incorrect definitions of YY_, issued by yacc.c when no parser header is
  generated, are removed.

  All the generated headers are self-contained.

** Header guards (yacc.c, glr.c, glr.cc)

  In order to avoid collisions, the header guards are now
  YY_<PREFIX>_<FILE>_INCLUDED, instead of merely <PREFIX>_<FILE>.
  For instance the header generated from

    %define api.prefix "calc"
    %defines "lib/parse.h"

  will use YY_CALC_LIB_PARSE_H_INCLUDED as guard.

** Fix compiler warnings in the generated parser (yacc.c, glr.c)

  The compilation of pure parsers (%define api.pure) can trigger GCC
  warnings such as:

    input.c: In function 'yyparse':
    input.c:1503:12: warning: 'yylval' may be used uninitialized in this
                              function [-Wmaybe-uninitialized]
       *++yyvsp = yylval;
                ^

  This is now fixed; pragmas to avoid these warnings are no longer needed.

  Warnings from clang ("equality comparison with extraneous parentheses" and
  "function declared 'noreturn' should not return") have also been
  addressed.
