No objections from me -- I'm just happy someone went through the
trouble of fixing all the issues necessary to make PTR_PLUS work.
When I looked at what it would take to break out pointer arithmetic
from normal arithmetic it looked to be rather ugly.
I haven't followed PTR_PLUS development at all -- what specifically
spurred you to hack on this Andrew?
