I did something very slightly incorrect, I think, though I don't
know what it was, because I got a working cross-port to freebsd
yesterday, on a box that had previously given me the stg_ap_v_ret
error. See yesterday's post of mine on that.
The i386-*-linux host is probably the best host, because of
header etc. compatibility. I always got a lot more pain when the
OS's were very different.

Try (or look at) the new hc-build script from cvs, Simon updated
that last night.
Also, see if there is anything in the building guide you might
have done slightly differently, as the build system is very fragile.
