Zoltan, consider your patch for parallel makes (the one which caused
unnecessary rebuilds).  The reason this caused extra rebuilds was that
dependencies went like

$(OBJS): proto

proto: FORCE
	# make prototypes

which behaved as if $(OBJS) depended on FORCE.  But we have other rules
like

init.o: zshpaths.h

zshpaths.h: FORCE
	# update zshpaths.h

that do not force rebuilds.  So I think you could get the effect you
wanted if you did something like

$(OBJS): .proto

.proto: FORCE
	# make prototypes

and included a .proto file in the distribution.  This system would have
the added benefit of totally confusing newcomers to the strange ways of
zsh Makefiles even more than they are already.
