Log Message:
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).

** 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:

  #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++/", "location.hh" would now include:

  #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.
