PR 15933
Partially revert patch of 2004-06-05.
* files.c (search_cache): Remove pfile argument. Don't check
for file that would be found by "" or <> search here...
(_cpp_find_file): ...do it here, before calling find_file_in_dir.
Do not apply directory-of-current-file correction to files
found by this check. Rearrange code slightly.
