You don't. Addresses are not portable at all, not even "rather".
I'm curious. Why do you need bitwise operations on addresses?
I did a lot of *eminently non-portable* bitwise operations on addresses
when I worked in avionics, so I know when to do them and when not to.
For the curious, the operations were in the low-level device driver for
a FLASH device, and in a bootloader.
