	Huh?  Somehow, I've got the habit of indenting text by one TAB
	(= 8 spaces) whenever possible.  I had this habit as of at least
	January 2002 (just checked the mail archive), and probably for a
	couple years longer.

	It's not the Make language implementation per se, just the
	scripts.  Since Autoconf was designed, in part, to enforce GNU
	Coding Standards, and since Scheme48 uses Autoconf, I see it
	like going against the flow to try to make it the other way
	around.  The result is the same either way, though.

	It's a workhorse.  Workhorses are like that.

	At the very least, the Makefile works with pmake(1).  I'm not
	quite fluent in the various Makes, but I've got the impression
	that $< will work for with any modern Make.
