Hi Christophe,

I had a look at it, it's mostly ppc32 code which I don't know well but
it looks like a very nice cleanup and it's good to be sharing the C
code here. All the common code changes look fine to me.

I'll take a closer look if you can rebase and repost the series I need
to create a tree and base 64e conversion on top of yours as they touch
the same common places.

Thanks,
Nick
