  Nope.  This is a bug.  Your original question only
mentioned zlib, which /does/ work as I described.
(And I know it works, because it's used by iostreams)
libjpeg.jam was unused, so it apparently didn't get
the same cleanup that I applied to bzip2 and zlib.
I'll try to fix this some time tomorrow along with
your other report and Peter's.
