The extra parens are there to denote this as an archive build.  However
you have to remove the extra space after $(LIBVUTL); that wasn't there
in Jeremy's original file.

However, it's definitely possible that this is causing the problem in
any event.  Try the alternative below.

Also you might check with the current release of GNU make to see if it
works any better.

And finally, you should run "make -d" and see why make decides that the
pattern rule doesn't match.  It generates a lot of output but you should
be able to determine which prerequisite causes make to give up on it.

That won't work, because a pattern rule with no recipe just deletes the
pattern.  You have to write the prerequisite rule with a real target,
such as:

    $(TSTS): (INCS) $(LIBVUTL)($OBJS)) $(LIBVLIB)
