Well, usual errors regarding to sizetype apply - you have to treat it
as sign-extending if you promote it to larger types (but I doubt that happens
or matters for ia64 as pointers should be DImode, right?).

But you should be able to spot code-gen differences and see where they
originate
from (the revision wasn't supposed to change code-gen though zero differences
wasn't really possible).

I'll wait for Erics investigation.  (ia64 is a dead architecture IMNSHO)
