>Description:
        make(1) manual page doesn't mention VPATH, which is specially processed 
variable. 
>How-To-Repeat:
        man make
>Fix:
        Add approximatly following passage to "Additional inbuilt variables":

        VPATH  Column-separated (":") lists of directories that make will
        search for files. The variable is supported for compatibility
        with old makes ONLY, use .PATH instead.
