I do not think that 6.6/9 is appropriate: What comes off this notation
is some integer type, it's for sure not an "address constant".
Address/pointer calculation is required to calculate that value,
though...

That sounds better:-) May I open a whishlist bug to get this
implemented?

However - I think leaving this to 6.6/10 isn't all that good. I'm
actually thinking about handing this one over to the C99 folks...

Or could this be a case for 6.6/6 - character constants?
