Right, but the current MAKEALL output does not make it easy to sort this 
out. Maybe we could change MAKEALL to distinguish between error and 
warning counts (and produce LOG/*.MAKELOG, LOG/*.ERR and LOG/*.WARN 
accordingly).

Agreed. However, I'd prefer it if no ARM board produced any warning -- 
granted, here it *looks like* many of these warnings are inocuous, and 
any new toolchain might produce some more, but if we don't keep the 
warning count at zero, then a less inocuous warning could creep in 
unnoticed.

There you are, then. :)

Got it -- actually, it is not a compiler issue, but a library issue: CS 
does compile for big-endian as well as little-endian, but does not 
provide big-endian libs 
(<http://www.codesourcery.com/sgpp/lite/arm/portal/kbentry36>, at least 
as I understand it). Apparently ELDK4.2 does not either. Would ELDK5.0 
have them? I haven't gotten around to setting it up.

Done, with a few hour's delay.
