My OP:

I have the following make file:

-------------------------------------------
all: something else

.PHONY: MakeAppleJuice MakeOrangeJuice MakeTomatoJuice

MakeAppleJuice:
	make_juice Apple.in.source  Apple.in.condition
				                    
MakeOrangeJuice:		                    
	make_juice Orange.in.source Orange.in.condition 
				                    
MakeTomatoJuice:		                    
	make_juice Tomato.in.source Tomato.in.condition 
-------------------------------------------

Is there anyway to combine the 3 rules into one? I hope there is, because
the 3 rules only different in what files they use and what juices then make
(but I still need the 3 phony targets).

I just tried "Empty Target Files" trick, 
http://www.gnu.org/software/autoconf/manual/make/Empty-Targets.html#Empty-Targets

-----------------------------------------------------------
$ cat Makefile 
make_juice := echo

all: something else

MakeJuice: $(wildcard *.in.source)
        $(make_juice) $? $(addsuffix .in.condition, $(patsubst %.in.source,%,$?))
        touch MakeJuice

$ make MakeJuice
echo Orange.in.source Tomato.in.source Orange.in.condition Tomato.in.condition
Orange.in.source Tomato.in.source Orange.in.condition Tomato.in.condition
touch MakeJuice

$ make MakeJuice
make: `MakeJuice' is up to date.
-----------------------------------------------------------

But that's different than my OP, because I need to deal with each juice
explicitly, and the command format is strictly 

 make_juice $*.in.source $*.in.condition 

So, is it possible to have such generic phony rule?

Thanks
