The function uffi-compat::%deref-pointer still calls
cffi::translate-type-from-foreign, but the method is no longer
available at least since the 31 may patch.
The same is true for %deref-pointer setf expander and
cffi::translate-type-to-foreign.
I tried to use cffi::translate-{from|to}-foreign and it seems to work.
