fold-const.c (fold_checksum_tree <case 't'>): Only look at TREE_VALUES if the EXPR is an ENUMERAL_TYPE. 

2004-06-13  Andrew Pinski  <pinskia@physics.uc.edu>

        * fold-const.c (fold_checksum_tree <case 't'>): Only
        look at TREE_VALUES if the EXPR is an ENUMERAL_TYPE.
        Only look at TYPE_MIN_VALUE and TYPE_MAX_VALUE if
        EXPR is an INTEGERAL_TYPE or a scalar float type.
