If you routinely do a ``make build'' to test your code, I'm
surprised you don't see the advantage.

But if you only selectively rebuild your tree then I suppose it's
not as big a timesaver.

I think it would also be of value on the machines that make
snapshots.  If ccache is deemed reliable, snapshots could be built
much more quickly.
