    Update to 2.5.1:

    * Noteworthy changes in release 2.5.1 (2012-06-05) [stable]

    ** Future changes:

      The next major release will drop support for generating parsers in K&R C.

    ** yacc.c: YYBACKUP works as expected.

    ** glr.c improvements:

    *** Location support is eliminated when not requested:

      GLR parsers used to include location-related code even when locations were
      not requested, and therefore not even usable.

    *** __attribute__ is preserved:

      __attribute__ is no longer disabled when __STRICT_ANSI__ is defined (i.e.,
      when -std is passed to GCC).

    ** lalr1.java: several fixes:

      The Java parser no longer throws ArrayIndexOutOfBoundsException if the
      first token leads to a syntax error.  Some minor clean ups.

    ** Changes for C++:

    *** C++11 compatibility:

      C and C++ parsers use "nullptr" instead of "0" when __cplusplus is 201103L
      or higher.

    *** Header guards

      The header files such as "parser.hh", "location.hh", etc. used a constant
      name for preprocessor guards, for instance:

      #ifndef BISON_LOCATION_HH
      # define BISON_LOCATION_HH
      ...
      #endif // !BISON_LOCATION_HH

      The inclusion guard is now computed from "PREFIX/FILE-NAME", where lower
      case characters are converted to upper case, and series of
      non-alphanumerical characters are converted to an underscore.

      With "bison -o lang++/parser.cc", "location.hh" would now include:

      #ifndef YY_LANG_LOCATION_HH
      # define YY_LANG_LOCATION_HH
      ...
      #endif // !YY_LANG_LOCATION_HH

    *** C++ locations:

      The position and location constructors (and their initialize methods)
      accept new arguments for line and column.  Several issues in the
      documentation were fixed.

    ** liby is no longer asking for "rpl_fprintf" on some platforms.

    ** Changes in the manual:

    *** %printer is documented

      The "%printer" directive, supported since at least Bison 1.50, is finally
      documented.  The "mfcalc" example is extended to demonstrate it.

      For consistency with the C skeletons, the C++ parsers now also support
      "yyoutput" (as an alias to "debug_stream ()").

    *** Several improvements have been made:

      The layout for grammar excerpts was changed to a more compact scheme.
      Named references are motivated.  The description of the automaton
      description file (*.output) is updated to the current format.  Incorrect
      index entries were fixed.  Some other errors were fixed.

    ** Building bison:

    *** Conflicting prototypes with recent/modified Flex.

      Fixed build problems with the current, unreleased, version of Flex, and
      some modified versions of 2.5.35, which have modified function prototypes.

    *** Warnings during the build procedure have been eliminated.

    *** Several portability problems in the test suite have been fixed:

      This includes warnings with some compilers, unexpected behavior of tools
      such as diff, warning messages from the test suite itself, etc.

    *** The install-pdf target work properly:

      Running "make install-pdf" (or -dvi, -html, -info, and -ps) no longer
      halts in the middle of its course.
