Subject Re: MD4/MD5 implementation is non-free
Date Mon, 16 Oct 2006 10:38:14 GMT
An argument has been made that the third-party MD4/MD5 code in APR 
(specifically, APR-util) is licensed such that it is not permissible to 
distribute modified works.

Could we get confirmation of this interpretation?  The license header 
reads as follows:
