But I see makeAConst as:static Node *makeAConst(Value *v){    Node *n;    switch (v->type)    {        case T_Float:
       n = makeFloatConst(v->val.str);            break;        case T_Integer:            n =
makeIntConst(v->val.ival);           break;        case T_String:        default:            n =
makeStringConst(v->val.str,NULL);            break;    }    return n;}
 

which uses makeStringConst().
