Subject: * Locale patch from Faidon:   - Adds a locale setting to setup files.
   - Proper local time, if the locale configuration option is used.   -
 Support for UTF-8 (or ISO-8859-X) filenames in SVN. Before this patch,    
 commiting (or even rcs_updating) on repositories with UTF-8 filenames was    
 impossible.
