I ran into something like this a while back, and discovered it's related to the 
-Os switch, and in fact the problem goes away if you change it to -O3 (and 
probably -O2 also).  Of course, not many people are interested in a speed tuned 
version of Nut/OS.

However, I didn't have time to dig into the makefile tangle far enough to change 
the cflags for the file(s) it caused problems on, nor to find which specific 
optimisation flag caused the error.
