The current DDJ has a series of articles on this; the source came from
the BSD386 project.  It's available on Compuserve via "GO DDJ".  (I'm
quoting from memory here.)  I loaned my tapes out, so I can't verify it,
but I could swear I saw some boot loader code in there, in the MK42
source distribution.  Also, someone recently posted a nice boot loader
in comp.sources.unix.

Just use a shell script for CC that hunts for CPATH and LPATH as environment
variables; this and some mild editing should do the trick.
