I would imagine you could do this using proper C with the Hi-Tech
compiler by using a union.  The Hi-Tech compiler uses "@" to locate
variables at specific hardware addresses; that's why you're getting the
"constant expected" error -- it's looking for a physical memory address.

Look at Hi-Tech's "bit" type.

All of the above is documented in the manual that's on the CD in the
"Features and Runtime Environment" section.
