Similar Strings - MySQL

Hey all, I'm trying to provide a feature to clean up duplicate data in a database I inherited. To do this, I'd like to have a Levenshtein String Distance UDF available, so that I can pick out duplicate names. The trouble is, the only UDFs I can find on the 'net are in source form - I'm on Windows (And targeting a Win32 MySql server), and have no C compiler available. Does anyone know of a binary version of these functions? The one available from this page looks interesting: http://empyrean.lib.ndsu.nodak.edu/~nem/mysql/udf/ Cheers, Nicholas Sherlock -- http://www.sherlocksoftware.org...

    Thanks, I'm slowly downloading Cygwin. In the meantime, I think I'll try
    to make a UDF in Delphi.
