如果你是在window环境下开发android，并关联到一些JNI的问题时，大家都得下载一个叫cygwin的软件，用这个软件我们就可以在windows环境下虚拟LINUX环境，从而对JNI进行编译，在安装cygwin时，有可能一些朋友会遇到下图这样的一个弹出窗口：
上面的内容如下：标题是Setup Alert ,内容是：This is the first time you've installed Cygwin 1.7.x. Please be advised that this is a major release. If you have not done so already , please check out the documentation athttp://cygwin.com/ to see how the upgrade could potentially affect any existing Cygwin installation.
If this is the first time you've installed Cygwin on this system ,then you can ignore this message.
之前我本人在安装cygwin时遇到这弹出窗口，都以为软件安装出错了，其实不然，
它的出现并不是说你的cygwin软件安装出错了，我们点击"确定"进入下一个界面，androidkaifa.com提示大家：它的出现对后面的软件安装不存在影响，
