OK, it has been 48 hours and I haven't seen any objections. The newlib
patch has now been committed.

I agree with Marcus' suggestion that we put the more comprehensive patch
(which requires the newlib fix) on trunk and my original patch (which does
not) on the release branches.

I'll go ahead with that later today.

Thanks,
