There is some backward compatibility code in the MD5DES and MD4DES
keyed hash implementation in our crypto library.  It appears to allow
validation of keyed MD5 or MD4 checksums where the sender did not
include a confounder.

The name macros controlling this compatibility code imply that they
were for the "Beta 5" release, which was more than 10 years ago.  Does
anyone still require this compatibility hack?
