   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.

NetBSD make at least doesn't set $< in explicit rules; nor does POSIX
make.  This is documented and intentional.  The manual for FreeBSD
make doesn't say one way or another whether $< (alternatively spelled
${.IMPSRC}) is defined in explicit rules, or if it is what value it
has.  Attached is a transcript of an attempt to build Scheme48 using
NetBSD make.  The last make incantation happened after I changed $^ to
$< in the makefile, which, as you can see, had no effect.

(`pmake' is the name of the ancestor of FreeBSD make, NetBSD make,
OpenBSD make, and probably several others.  Its descendants are all
fairly similar to one another.  I don't know whether the original
pmake is still maintained separately.)
