ZooKeeper C客户端编译错误

编写zookeeper客户端程序出现以下编译错误：

/usr/local/include/zookeeper/recordio.h:76: error: expected unqualified-id before ‘__extension__’
/usr/local/include/zookeeper/recordio.h:76: error: expected ‘)’ before ‘__extension__’
/usr/local/include/zookeeper/recordio.h:76: error: expected unqualified-id before ‘)’ token

解决方法在http://blog.csdn.net/falcon2000/article/details/6895784

recordio.h:76 声明了htonll函数，其他文件可能对htonll做了宏定义，修改如下：

#ifndef htonll

int64_t htonll(int64_t v);

#endif
