关于proftpd 编译时出错，请高手看看先。。累了我两天了：（

徘徊边缘

软件版本：proftpd-1.2.8p  proftpd-1.2.9rc1  proftpd-1.2.9rc2  proftpd-1.2.9rc3都使用过，出现相同的问题。

但在之前编译其他软件如：apache..mysql..qmail.vpopmail 的时候却没有出现使何错误。
./configure时都出现这个错误。。

gcc已经安装
[root@localhost proftpd-1.2.8]# rpm -q gcc
gcc-3.2.2-5

glibc也已经安装
[root@localhost proftpd-1.2.8]# rpm -q glibc
glibc-2.3.2-11.9
