One of the very popular C compilers for CP/M used to not be smart enough to
optimize a post-increment with no side-effects. (At least, not be default.
It's been a while.)  So while this may have been a valid concern back in the
days of 64K address spaces, I would be surprised if any compilers written in
the last 5 years were thus limited.
