I tried that, but it did nothing.  Of course exit 1 works, but throws an
error, and exec exit 0 doesn't work either, throws an error.

Nothing, but the point is that draft is a modifier and it isn't clear
from that syntax that draft is a modifier and not a target.

The problem is that the 'gmake' recursion is done, but then returns and
runs the hhml again, so 'gmake draft html' calls "$(MAKE) html DRAFT=Y"
and on return from that, the html is called again and rebuilds, so it
isn't really draft.
