+ *  file_time() - get timestamp of file, if not done by file_dirscan()
+ *  file_archscan() - scan an archive for files
+ *
+ * File_dirscan() and file_archscan() call back a caller provided function
+ * for each file found.  A flag to this callback function lets file_dirscan()
+ * and file_archscan() indicate that a timestamp is being provided with the
+ * file.   If file_dirscan() or file_archscan() do not provide the file's
+ * timestamp, interested parties may later call file_time().
+ *
+ * 07/10/95 (taylor)  Findfirst() returns the first file on NT.
+ * 05/03/96 (seiwald) split apart into pathnt.c
