void add_cpp_dir_path ( )

Add P to the chain specified by CHAIN.

static void add_env_var_paths ( )

static

Read ENV_VAR for a PATH_SEPARATOR-separated list of file names; and
   append all the names to the search path CHAIN.

void add_path ( )

Add PATH to the include chain CHAIN. PATH must be malloc-ed and
   NUL-terminated.

static

Free an element of the include chain, possibly giving a reason.

	)

Referenced by register_include_chains().

static void merge_include_chains ( )

static

Merge the four include chains together in the order quote, bracket,
   system, after.  Remove duplicate dirs (determined in
   system-specific manner).

   We can't just merge the lists and then uniquify them because then
   we may lose directories from the <> search path that should be
   there; consider -iquote foo -iquote bar -Ifoo -Iquux.  It is
   however safe to treat -iquote bar -iquote foo -Ifoo -Iquux as if
   written -iquote bar -Ifoo -Iquux.

		const char *	sysroot,
		const char *	iprefix,

	)

Exported function to handle include chain merging, duplicate
   removal, and registration with cpplib.

		struct cpp_dir *	head,
		struct cpp_dir *	system,
		struct cpp_dir *	join,
		int	verbose
	)

staticread

For each duplicate path in chain HEAD, keep just the first one.
   Remove each path in chain HEAD that also exists in chain SYSTEM.
   Set the NEXT pointer of the last path in the resulting chain to
   JOIN, unless it duplicates JOIN in which case the last path is
   removed.  Return the head of the resulting chain.  Any of HEAD,
   JOIN and SYSTEM can be NULL.

void split_quote_chain ( void )

Use given -I paths for #include "..." but not #include <...>, and
   don't search the directory of the present file for #include "...".
   (Note that -I. -I- is not the same as the default setup; -I. uses
   the compiler's working dir.)
