I assume that's what INSTALL_AS_USER is for: if you really want to
install as a non-root user, presumably to someplace besides the default.

OK, I see your concern now - environment pollution.  Initially, I did
try to have the su'ed make be passed only the same environment vars
as were given on the invoking make's command line, which should work the
same, and would let us use 'su -'.

But, although the man page makes it sound kind of like .MAKEFLAGS can do
that, it can't.  So, unfortunately, to even be able to go down this
route safely would require some modifications to make(1).  (btw Joerg:
have you tried my synch-make-with-FreeBSD-CURRENT patch yet?)

OK, I'll work on making it a warning message tonight.  Thanks for the
explanation.
