make zhcon 出错，提示OPEN_MAX设置太大，需设置成默认的64，如何修改？

slackware10.1 FULL安装。
make zhcon 出错，
make时出现错误，如下：
In file included from /usr/include/c++/3.3.4/backward/strstream:51,
from zhcon.cpp:23:

提示OPEN_MAX设置太大，需设置成默认的64，如何修改？
我看以前的帖子也有问过，但没解决。

我没找到 OPEN_MAX在哪里修改。
高手提示下。THANK

使用tgz安装解决。

在zhcon-0.2.3/src/下的inputclient.h和mouse.cpp中加入include <assert.h>
make时依然出错。
