1418         Partially revert patch of 2004-06-05.
1419         * files.c (search_cache): Remove pfile argument.  Don't check
1420         for file that would be found by "" or <> search here...
1421         (_cpp_find_file): ...do it here, before calling find_file_in_dir.
1422         Do not apply directory-of-current-file correction to files
1423         found by this check.  Rearrange code slightly.
