As discussed on IRC, I've applied it to `wip' for now, but it makes two
tests fail on x86_64:

    mescc-lib/lib/tests/scaffold/16-cast 
    [2]19:47:07 janneke@drakenpad:~/src/mes/wip-x86_64

    mescc-lib/lib/tests/scaffold/17-compare-unsigned-le
    [1]19:45:39 janneke@drakenpad:~/src/mes/wip-x86_64 

Greetings,
Janneke
