Arbitrary precision representation for numeric constants?

Hello again,

Okay, maybe the tree node dump was too complicated. ;-)

So once more:

When I use fold() to multiply two `unsigned long long'
constants, the result does not get the "overflow" bit set
(even if it overflows).

Anything that can be done about this?
