- appeared between the quotes in a #include directive; it can be
- determined implicitly from the hash table location or explicitly
- from FILE->name.
-
- FILE is a structure containing details about the file that was
- found with that search, or details of how the search failed.
-
- START_DIR is the starting location of the search in the include
- chain. The current directories for "" includes are also hashed in
- the hash table and therefore unique. Files that are looked up
- without using a search path, such as absolute filenames and file
- names from the command line share a special starting directory so
- they don't cause cache hits with normal include-chain lookups.
-
- If START_DIR is NULL then the entry is for a directory, not a file,
- and the directory is in DIR. Since the starting point in a file
- lookup chain is never NULL, this means that simple pointer
- comparisons against START_DIR can be made to determine cache hits
- in file lookups.
-
- If a cache lookup fails because of e.g. an extra "./" in the path,
- then nothing will break. It is just less efficient as CPP will
- have to do more work re-preprocessing the file, and/or comparing
- its contents against earlier once-only files.
