True, but I often just stick the optimization flag in the Makefile
and don't bother to turn it off during testing. Anyhow, the question I
answered was why one might want to write a "useless" code fragment.
I agree that a compiler that optimizes such a fragment into nothingness
is not a problem if one can disable the optimization.
