+       * src/parse-gram.y: Fix minor problems uncovered by lint.
+       (current_lhs, current_lhs_location): Now static.
+       (current_assoc): Remove unused variable.
+
+       Cleanups so that Bison-generated parsers have less lint.
+       * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
+       Prepend /*ARGSUSED*/, for lint's sake.
+       * data/glr.c (YYUSE): Properly parenthesize, and use an alternate
+       definition if 'lint' is defined.
+       (YYID): New macro (or function, if lint).
+       All uses of /*CONSTCOND*/0 replaced by YYID(0).
+       * data/yacc.c: Likewise.
+       * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
+       (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
+       * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
+       is C++ only.
+       * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
+       * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
+       Use YYID(0) rather than 0, for lint.
+       (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.
+       (yysyntax_error): Rewrite to avoid lint warnings about parenthesization.
