I've being trying to stop gcc using too many registers in another
project - with 24 available registers you'd think it would manage
not to spill locals to the stack! But no, the 'status function'
(which just copies info into a big buffer with a few local actions)
managed to generate temporaries all of its own!  In this case marking
the target buffer 'volatile' helped no end!
