The source already had md5 (in libs/md5lib/) so MD5 wasn't a problem.
I've pulled a public domain implementation of md4 from dovecot, as it
looks like some other projects have done the same [1]. I spent some
time looking at restoring mhash on Windows but it's non trivial and
since all we use are those hashing functions it's not worth it.
