Yes. The Linux case seems to work (there are lots of little differences
in the C ABIs between Darwin/Linux), but the Darwin case is pretty

I think that it's limited to :ADDRESS -> MACPTR (which is documented)
and to :SINGLE-FLOAT -> SINGLE-FLOAT and :DOUBLE-FLOAT -> DOUBLE-FLOAT

64-bit integers, but I don't think that this happens in practice.
