Beg pardon, but did you examine the Newsgroups: line?  The System III/System
V (and, I believe, recent SunOS) "make", sometimes called "augmake", *does*
support this.  It's fairly limited, however; it only substitutes at the end
of words, and there are no wildcards.

I have noticed that *some* recursive substitutions fail; I don't know why.
It doesn't seem to matter whether substitutions are involved or not.  (I had
the biggest problem with imported environment variables.)
