+       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.
