One proposed solution to this was to use a functioned called
mergesort().  A patch was provided that includes a compatibility
function for systems that don't include mergesort():

I just put a diff into the patches dir that implements the --md5 option
(extracted and cleaned up from a larger patch set that was sent to me by
Wolfgang Neuman):

As you'd expect, this tells rsync to use MD5 checksums instead of MD4.
