Not yet.  It never occured to me that one would be needed because the
necessary setup was totally obvious.  Clearly I was mistaken.  :)

This seems right so far.

I haven't a clue why this would happen.  You _do_ have libc5-altdev and
altgcc installed, right?  Try using i486-linuxlibc1-gcc instead of -b
i486-linuxlibc1.  If that still dosen't work, mail me with the details
of what you're doing and I'll see what I can do.
