        * camel-search-private.c: Removed unwanted header.  It was never
        put in for a reason.  Stop fixing irrelevant warnings.

        (camel_ustrstrcase): Our own strstrcase impl for utf8 strings.
        (camel_ustrcasecmp): Ditto for strcasecmp.
        (camel_ustrncasecmp): And strncasecmp.
        (utf8_get): Simpler interface to utf8 string processing.
        (camel_search_header_match): Use the new things.

2001-02-05  Not Zed  <NotZed@Ximian.com>

        * camel-folder.c (get_summary): Removed some old variables/a small
        memleak.
        (free_summary): Removed old variables.

        * camel-mime-utils.c (header_raw_check_mailing_list): New utility
        function to get the mailing list (if any) that a set of headers
        came from.
