+       Prepare for the possibility of a 2.5.1 release.
+       * NEWS (2.5.1): New heading.

+
+       Version 2.5.

+
+       Don't use IF_LINT in Bison sources.
+       It creates unnecessary differences between the sources that Bison
+       maintainers build and test (given that maintainers normally
+       configure with --enable-gcc-warnings) and the sources that Bison
+       users build.  Instead, use PACIFY_CC, which doesn't.  This change
+       fixes compiler warnings reported by Tys Lefering at
+       <http://lists.gnu.org/archive/html/bison-patches/2011-05/msg00004.html>.
+       * configure.ac: Don't AC_DEFINE lint regardless of the configure
+       options.  This change affects imported gnulib sources, where
+       IF_LINT still appears and depends on lint.
+       * src/scan-gram.l, src/scan-skel.l: Replace uses of IF_LINT with
+       PACIFY_CC.
+       * src/system.h (IF_LINT): Remove cpp macro.
+       (PACIFY_CC): New cpp macro.

+
+       Fix precedence for end token.
+       Since Bison 2.3b, which restored the ability of precedence
+       directives to assign user token numbers, doing so for user token
+       number 0 has produced an assertion failure.
+       * NEWS (2.5): Document fix.
+       * src/symtab.c (symbol_user_token_number_set): In the case of the
+       end token, don't decrement ntokens if it was never incremented.
+       * tests/regression.at (Token number in precedence declaration):
+       Extend.
