Right! That is my problem you see... I have a rule to apply to prerequisites, I 
have to have it for other purposes.  


Target%: prerequisite0% prerequisite1%

prerequisite0%: ...


I need all these things, yet, I want the rule for target% to only apply if 
prerequisite0% actually exists.  I do not want to chain with the rule for 
prerequisite0%, I do want to chain with the rule for prerequisite1%.  

If I put target%:, I chain with both.  If I put target%::, I chain with none.  
I want to chain with exactly one of them.
