I am pretty sure that our MD5 algorithm is slightly modified.  I remember
when we put MD5 into Apache 1.3 we found that the BSD platforms had used a
modified MD5 algorithm.  I can't remember if we took theirs, or somebody
elses implementation.  I do remember that one of the reasons we don't just
wrap the platform MD5 algorithm, is so that we know the resoluts from our
MD5 algorithm are portable to other platforms.
