Gnu make manual suggestion to clarify $< in multiple rules:

[John Ulvr (julvr)]

In gnu make manual, I would like to suggesting adding the following text in the 
10.5.3 Automatic Variables section:


$<
   The name of the first prerequisite. If the target got its recipe from an 
implicit rule, this will be the first prerequisite added by the implicit rule 
(see Implicit Rules).  If the target is not from a non-implicit rule, this will 
be the first prerequisite of the rule containing the recipe if one exists, or 
alternatively the first prerequisite of the target named in any rules without 
recipes.


Thanks,

John
