The issue is not so much fairness, as meaningfulness of the
results. When people publish comparative timings, you sort
of assume that the subtext is:
"look and see which compiler is faster"
But if you don't take care to make the figures meaningful,
the true subtext is something like:
"here are some random non-comparable figures from which nothing
can be usefully deduced"
