This regression was introduced by the following patch:

 2003-09-16  Roger Sayle  <roger@eyesopen.com>

        * fold-const.c (tree_swap_operands_p): New function to determine
        the prefered ordering of operands.
        (fold): Numerous clean-ups.  Use tree_swap_operands_p when swapping
        operands to commutative, comparison or ternary operators.  Replace
        uses of TREE_SET_CODE with recursive call to fold.  Remove duplicate
        transformation of A ? B : C into !A ? C : B.
