+
+ * src/parse-gram.y: Fix minor problems uncovered by lint.
+ (current_lhs, current_lhs_location): Now static.

+
+ 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.

+ All uses of /*CONSTCOND*/0 replaced by YYID(0).
+ * data/yacc.c: Likewise.
+ * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
+ (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.

+ 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.
