It is in svn under http://www.crosswire.org/svn/jsword/trunk/common/
Test cases at http://www.crosswire.org/svn/jsword/trunk/common/src/
(note diff_patch_match.java in test is going away.)
For an example of how I use it see: http://www.crosswire.org/svn/
(This code will be moved to a better place. Right now this location
is a hack. So snag a copy soon.)
Wikipedia has lots of C code for the fundamental algorithms. So you
can use those to help you port it to C/C++.
If you do port it and add it to Sword, I'll be glad to maintain my
version and Sword's in parallel.
One of the things I hope to do is change the algorithm to difference
entire words rather than characters.
Also the performance is adequate in both time and space if it is used
a verse at a time and on no more than 50 or so verses.
There is one class in there that is not related to producing/using
diffs and that is Distance. I just added it to allow me to guess at a
module name from malformed input.
I'm probably going to do a bit more cleanup on it. (e.g. parameter
and variable name changes, add documentation, fix documentation, ...)
