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

** 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.
