We can add it in a NetBSD Source ifdef

I'm not sure why we use uint64_t. It could predate uintptr_t. What does=20
cvs blame say?

As a side issue, I'd expect that if we add a UINT64TOPTR(), we only need=20
to define it such that given void *p; p =3D=3D UINT64TOPTR(PTRTOUINT64(p)) =
.=20
i.e. it only needs to invert PTRTOUINT64().

Another issue might be to instead define UN_PTRTOUINT64(). :-)

Take care,
