+ 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.
