Update to 3.0.2:

* Noteworthy changes in release 3.0.2 (2013-12-05) [stable]

** Bug fixes

*** Generated source files when errors are reported

  When warnings are issued and -Werror is set, bison would still generate
  the source files (*.c, *.h...).  As a consequence, some runs of "make"
  could fail the first time, but not the second (as the files were generated
  anyway).

  This is fixed: bison no longer generates this source files, but, of
  course, still produces the various reports (*.output, *.xml, etc.).

*** %empty is used in reports

  Empty right-hand sides are denoted by '%empty' in all the reports (text,
  dot, XML and formats derived from it).

*** YYERROR and variants

  When C++ variant support is enabled, an error triggered via YYERROR, but
  not caught via error recovery, resulted in a double deletion.

* Noteworthy changes in release 3.0.1 (2013-11-12) [stable]

** Bug fixes

*** Errors in caret diagnostics

  On some platforms, some errors could result in endless diagnostics.

*** Fixes of the -Werror option

  Options such as "-Werror -Wno-error=foo" were still turning "foo"
  diagnostics into errors instead of warnings.  This is fixed.

  Actually, for consistency with GCC, "-Wno-error=foo -Werror" now also
  leaves "foo" diagnostics as warnings.  Similarly, with "-Werror=foo
  -Wno-error", "foo" diagnostics are now errors.

*** GLR Predicates

  As demonstrated in the documentation, one can now leave spaces between
  "%?" and its "{".

*** Installation

  The yacc.1 man page is no longer installed if --disable-yacc was
  specified.

*** Fixes in the test suite

  Bugs and portability issues.
