	* files.c (file_hash_eq): Use filename_cmp
	instead of strcmp.
	(nonexistent_file_hash_eq): Likewise.
	(remap_filename): Likewise.
	Handle absolute DOS-path,
	(append_file_to_dir): Check for IS_DIR_SEPARATOR
	instead of slash.
	(read_name_map): Likewise.
	* linemap.c (linemap_add): Use filename_cmp
	instead of strcmp.
	* mkdeps.c (apply_vpath): Use filename_ncmp
	instead of strncmp.
	(deps_restore): Use filename_cmp instead of
	strcmp.
	* init.c (read_original_directory): Use
	IS_DIR_SEPARATOR instead of checking for slash.
