> “如果将源包也标准化，就可以” 是的。 对于没有标准化的旧zip的处理，只能保证生成逻辑上一致的zip包，而不会二进制完全一致。 而为了完全一致，需要将源包也标准化。 设计：当新zip包中的文件数据没有修改的时候，算法会直接从旧zip包中copy压缩好的源文件，从而节省重新压缩数据时耗费的时间。 注意：在zipdiff的时候，二进制不完全一致时会有一个输出提示。

我对QNX系统不熟悉，看起来有和linux类似的opendir readdir closedir函数组合； 是否能够合并两种代码分支，而在不同的API特性的情况下才做一些特殊处理（用_QNX_宏）？ （不是强制要求，现在看来分开可能更清晰）
