Nope.  

In mmotm, only the original patch plus your first fix is there:

$ curl -sO http://www.ozlabs.org/~akpm/mmotm/broken-out.tar.gz
$ tar -tavf broken-out.tar.gz |grep gcc-473

but in mmots, the additional ptch from me, plus another comment fixup
from you are also there:

$ curl -sO http://www.ozlabs.org/~akpm/mmots/broken-out.tar.gz
$ tar -tavf broken-out.tar.gz |grep gcc-473
