15 * Wed Feb 8 12:51:48 1995, biro@yggdrasil.com (Ross Biro): allow all port
16 * numbers to be specified on the command line.
18 * Fri, 8 Mar 1996 18:01:39, Swen Thuemmler <swen@uni-paderborn.de>:
19 * Omit the call to connect() for Linux version 1.3.11 or later.
21 * Wed Oct 1 23:55:28 1997: Dick Streefland <dick_streefland@tasking.com>
22 * Implemented the "bg", "fg" and "retry" mount options for NFS.
24 * 1999-02-22 Arkadiusz Mi¶kiewicz <misiek@pld.ORG.PL>
25 * - added Native Language Support
27 * Modified by Olaf Kirch and Trond Myklebust for new NFS code,
30 * 2006-06-06 Amit Gud <agud@redhat.com>
31 * - Moved with modifcations to nfs-utils/utils/mount from util-linux/mount.
