Well, that's not quite the same thing; it hooks in through some kind
of preload rather than through the normal mechanism.  And I think that
is replacing ccache rather than distcc, but you could hook it in a the
same point.

It would probably not take a very big change to distcc to do it.  In
fact, it probably wouldn't take any change to distcc, you could do it
just by installing it with the right changes.  

I still don't understand why Benjamin thinks it would be a good idea.

I was talking to bje at lunchtime and realized that the cc1 technique
probably won't work with modern gcc versions, which may default to
using the integrated cpp.
