net-tools编译问题的解决
net-tools是Linux下一个软件包，里面包含了很多网络工具，比如arp、ifconfig、ipmaddr、iptunnel、route、nameif、mii-tool等等。
具体参看如下链接：
http://net-tools.sourceforge.net/
http://net-tools.berlios.de/
http://en.wikipedia.org/wiki/Ifconfig
http://www.linuxfoundation.org/collaborate/workgroups/networking/net-tools
从sourceforge上下载最新的net-tools-1.60源码之后解压编译：
[root@localhost net-tools-1.60]# uname -a Linux localhost.localdomain 2.6.38.8 #4 SMP Mon Oct 31 20:49:48 CST 2011 x86_64 x86_64 x86_64 GNU/Linux [root@localhost net-tools-1.60]# ls ABOUT-NLS COPYING INSTALLING lib nameif.c po route.c TODO arp.c hostname.c intl.h Makefile netstat.c rarp.c RPM config.in ifconfig.c ipmaddr.c man nls README slattach.c configure.sh include iptunnel.c mii-tool.c plipconfig.c README.ipv6 statistics.c [root@localhost net-tools-1.60]# make config rm -f config.h Configuring the Linux net-tools (NET-3 Base Utilities)... ...

出错，打上补丁，gcc-3.4.patch补丁代码为：

编译还是出错：

再打补丁，net-tools-1.60-2.patch补丁代码为：
