Hi Kevin,
Unfortunately it looks like m32r doesn't have the io{read,write}32be
accessors. I don't know if any other architechture is affected by
that, but I've dropped the series from my tree for the time being.
There will need to be a solution, either to added the accessors to
m32r, or to not build that code if the accessors aren't there.
