I can't remember how my logic went. Should have written more of it
down.
Some day, I think we're going to need to do as Mark and Michael
suggested; stop using CORE_ADDR so indiscriminately as a convenient
integer type. In the mean time, perhaps everywhere that doesn't
define integer_to_address should get a better default, or the fallback
case in value_as_address should be changed, so that this is fixed
equally on other platforms.
