FYI, the self-generated source code from the Unicode Character Database and some related algorithms were updated with latest official version of the standard (5.1), released in April 4, 2008.
BTW, I think would be good to write some documentation explanining how to use the build-aux/ programs to update the autogenerated Unicode source code. What do you think? A README.Unicode file in build-aux/ could contain those explanations.
