Its a nice try at the problem, but it doesn't work, for
the reason you noted.

The move-if-change saves the timestamp update so the compile
won't happen again, but it also leaves the header out-of-date
with respect to the sources it depends on.  Hence, the
mumble-stamp mumbo-jumbo.  The solution requires either
using check sum stamps for dependency analysis, or the
``dont-worry-about-this-dependency'' hint.  I really do not
want make rebuilding my generated sources, even if it 
does throw it away.
